专利说明:

[001] The present invention relates to a smoking system having a liquid storage portion.
[002] WO 2007/078273 describes an electrical smoking system that uses a liquid as an aerosol-forming substrate. The liquid is stored in a container made of a porous material. The container communicates with a heating vaporizer, powered by a battery source, through a series of smaller openings. In use, the heater is activated by the user's mouth to turn on the battery power source. In addition, suction at the nozzle by the user causes air to be drawn through the porous container for the liquid, over the heating vaporizer, and at the nozzle and subsequently in a user's mouth.
[003] The prior art electric smoking heating systems, including the one mentioned above, have a number of advantages, but there is still room for improvement. It is therefore an objective of the invention to provide an improved smoking system.
[004] In accordance with a first aspect of the invention, a smoking system is provided comprising: a capillary wick for maintaining the liquid; at least one heater for heating the liquid in at least a portion of the capillary wick to form an aerosol; at least one air inlet, at least one air outlet and a chamber between the air inlet and air outlet, the air inlet, the air outlet and the chamber being arranged in order to define an air flow route from the air inlet to the air outlet through the capillary wick in order to conduct the aerosol to the air outlet; and at least one guide for channeling the air flow in the air flow route, in order to control the particle size in the aerosol.
[005] In use, when the heater is activated, the liquid in at least a portion of the capillary wick is vaporized by the heater to form a supersaturated vapor. Supersaturated steam is mixed with and transported in the air stream from at least one air inlet. During the flow, the vapor condenses to form an aerosol in the chamber, and the aerosol is transported to the air outlet in a user's mouth. In this specification, the relevant upstream and downstream positions are described in relation to the direction of the air flow as it is pulled from the air inlet to the air outlet.
[006] The smoking system according to the invention provides a number of advantages. Most significantly, at least one guide improves the air and aerosol flow through the smoking system. In particular, the management of air and aerosol flow through the smoking system by the guides allows any control of air flow upstream of the capillary wick or control of air and aerosol flow downstream of the capillary wick or both. The inventors have observed that air flow management, in particular the direction of the air flow and the speed of the air flow, allows the particle size in the resulting aerosol to be controlled and preferably reduced compared to known devices. This improves the smoking experience. In addition, the aerosol flow and air controller can reduce the amount of liquid condensation on the inner surface of the smoking system. Such condensation can leave the smoking system and cause inconvenience to the user. The air and aerosol flow controller can reduce such leakage. In addition, the air and aerosol flow controller can result in increased system efficiency and resulting energy savings.
[007] The liquid has physical properties, for example, a boiling point suitable for use in the smoking system: if the boiling point is too high, at least one heater will not be able to vaporize the liquid in the capillary wick, but , if the boiling point is too low, the liquid can vaporize even without at least one heater being activated. The liquid preferably comprises a tobacco-containing material comprising volatile tobacco flavor compound which is released from the liquid after heating. Alternatively, or in addition, the liquid may comprise a non-tobacco material. The liquid can include water, solvents, ethanol, plant extracts and natural or artificial flavors. Preferably, the liquid further comprises an aerosol former. Examples of suitable aerosol builders are glycerin and polypropylene glycol.
[008] In a preferred embodiment of the invention, the smoking system further comprises a liquid storage portion. Preferably, the capillary wick is arranged to be in contact with the liquid in the liquid storage portion. In this case, in use, the liquid is transferred from the liquid storage portion to the heater through the capillary action on the capillary wick. In one embodiment, the capillary wick has a first end and a second end, the first end extending to the liquid storage portion for contact with the liquid therein and at least one heater being arranged to heat the liquid at the second end. When the heater is activated, the liquid at the second end of the capillary wick is vaporized by the heater to form supersaturated steam.
[009] An advantage of this modality is that the liquid in the liquid storage portion is protected from oxygen (because oxygen cannot generally enter the liquid storage portion through the capillary wick) and, in some clear embodiments, from so that the risk of liquid degradation is significantly reduced. For this reason, a high level of hygiene can be maintained. Using a capillary wick extending between the liquid and the heater, it allows the structure of the system to be relatively simple. The liquid has physical properties, including viscosity, which allows the liquid to be transported through the capillary wick through the capillary action.
[0010] The liquid storage portion is preferably a container. Preferably, the liquid storage portion does not include any porous material, so that there is only the single capillary mechanism (the capillary wick) in the smoking system. This keeps the structure of the smoking system simple and the entire system low maintenance. Preferably, the container is opaque, thus limiting the degradation of the liquid through light. The liquid storage portion may not be refillable. Thus, when the liquid in the liquid storage portion has been used, the smoking system is replaced. Alternatively, the liquid storage portion may be refillable. In this case, the smoking system can be replaced after a certain number of refills of the liquid storage portion. Preferably, the liquid storage portion is arranged to hold the liquid for a predetermined number of breaths.
[0011] The capillary wick may have a fibrous structure or healthy sponge. For example, the capillary wick may comprise a plurality of fibers or threads. The fibers or threads can generally be aligned in the longitudinal direction of the smoking system. Alternatively, the capillary wick may comprise sponge-like material formed into a rod shape. The rod shape can extend along the longitudinal direction of the smoking system. The wick structure forms a plurality of smaller holes or tubes, through which the liquid can be transported to the heater, through the capillary action. The capillary wick can comprise any suitable material or combination of materials. Examples of suitable materials are ceramic or graphite-based materials in the form of sintered fibers or powders. The capillary wick can have any suitable capillarity and porosity in order to be used with different liquid physical properties such as density, viscosity, surface tension and vapor pressure. The capillary properties of the wick, combined with the properties of the liquid, ensure that the wick is always moist in the heating area. If the wick is dry, it can overheat, which can lead to thermal degradation of the liquid.
[0012] Preferably, at least one of the air flow guide channels controlling the air flow speed, that is, the air flow speed and the air flow direction. This may be directing the air flow in a particular direction. Alternatively or additionally, this can be by controlling the speed of the air flow. The speed of the airflow can be controlled by varying the cross-sectional area of the airflow route in order to take advantage of the Venturi Effect. Air flow through an increased constriction section at speed in order to satisfy the continuity equation. Similarly, air flow through the shortened widest section in speed.
[0013] Preferably, at least one guide is arranged so that the speed of the air flow over the wick is greater than the speed of the air flow upstream of the wick. This is preferably achieved by the guides defining a cross section of the air flow constricted on the wick, which will force the air flow to accelerate.
[0014] Preferably, at least one guide is arranged to control the particle size of the aerosol to have a diameter substantially less than 1.5 micro meters (μm). Even more preferably, at least one guide is arranged to control the particle size of the aerosol to have a diameter substantially less than 1.0 micro meters (μm).
[0015] In one embodiment, the smoking system still comprises a housing and at least one guide for channeling the air flow is provided by the internal shape of the housing. That is, the internal form of the assembly of the airflow channels. Preferably, the inner surface of the enclosure walls is shaped to form guides for the airflow channel. The guides provided by the inner shape of the wrapper can be provided upstream of the capillary wick. In this case, the channels guide the air flow from the air inlet to the capillary wick. Alternatively or in addition, the guides provided by the inner shape of the wrapper can be provided downstream of the capillary wick. In this case, the guide channels of the aerosol and the air flow from the capillary wick to the air outlet. In a preferred embodiment, the inner shape of the enclosure defines a tapered channel for the air outlet.
[0016] The internal shape of the wrapper can define a linear flow upstream or downstream of the capillary wick. The internal shape of the wrapper can define a wheelset, that is, rotation or spiral, flow upstream or downstream of the capillary wick. The inner shape of the wrapper can define any turbulent flow upstream or downstream of the capillary wick.
[0017] The smoking system can further comprise a housing and the internal shape of the housing can at least partially define the shape of the chamber. The size and shape of the chamber affects the air and aerosol flow from the capillary wick to the air outlet, which affects the process of aerosol formation. This affects the size of the aerosol particles. For example, if the chamber is small, this will encourage rapid movement of the aerosol particles towards the air outlet. On the other hand, if the chamber is larger, this may allow more time for the aerosol to form and flow to the air outlet. The chamber can surround the capillary wick or it can be downstream of the capillary wick. The position of the chamber relative to the capillary wick also affects the size of the aerosol particles. This is because it affects how quickly the vapor condenses to form the aerosol.
[0018] In one embodiment, the smoking system comprises an enclosure and the enclosure is formed internally downstream of the capillary wick to form a pendulum to trap larger aerosol particles. Larger aerosol particles can be those aerosol particles that have a diameter greater than about 1.5 micro meters. Alternatively, larger aerosol particles can be those aerosol particles that have a diameter greater than about 1.0 micro meters. Alternatively, larger aerosol particles can include those aerosol particles having other sizes. The greater inertia of the larger aerosol particles means that if the airflow route includes a sharp change in direction, the larger aerosol particles may not be able to change the direction quickly enough to remain in the airflow route and may instead of being held by the pendulum. The pendulum is preferably positioned to take advantage of the increased thrust of the larger aerosol particles.
[0019] The position of the pendulum, for example, relative to the capillary wick and heater and relative to the chamber, will affect the size and number of particles that are trapped. If the smoking system comprises a pendulum, at least one guide may include an acceleration nozzle for directing the aerosol towards the pendulum. The nozzle can define a decrease in the cross-sectional area of the airflow route in order to accelerate the aerosol for the pendulum. Larger aerosol particles become trapped on the pendulum, while smaller aerosol particles can deviate around the pendulum in the flow path.
[0020] In one embodiment, the smoking system still comprises an enclosure, and at least one guide for channeling the air flow is provided by one or more removable inserts contained in the enclosure. The one or more removable inserts may include a removable insert upstream of the capillary wick. In this case, the channel guides the air flow from the air inlet to the capillary wick and heater. Alternatively or in addition, the one or more removable inserts may include a removable insert downstream of the capillary wick. In this case, the channel guides the aerosol and air flow from the capillary wick and heater to the air outlet. One or more removable inserts can channel the air flow directly into the capillary wick and heater. One or more removable inserts can channel the air flow directly out of the capillary wick and heater.
[0021] One or more removable inserts can define a linear flow upstream or downstream of the capillary wick and heater. One or more removable inserts can define a wheelset, that is, rotation or spiral, flow upstream or downstream of the capillary wick. One or more removable inserts can define any turbulent flow upstream or downstream of the capillary wick.
[0022] The one or more removable inserts can at least partially define the shape of the chamber. This will generally be a combination with the inner shape of the wrapper, but that is not necessarily the case. The size and shape of the chamber affects the air and aerosol flow from the capillary wick and heater to the air outlet. This affects the size of the aerosol particles. The chamber can surround the capillary and heater wick or it can be downstream of the capillary and heater wick. The position of the chamber relative to the capillary wick and heater also affects the size of the aerosol particles.
[0023] In a preferred embodiment, the one or more removable inserts includes a removable insert surrounding the capillary wick and heater. In this case, preferably the removable insert defines the flow route directly to the capillary and heater wick and directly out of the capillary and heater wick. In a first embodiment, the capillary wick is elongated and the removable insert directs the airflow over the capillary wick in a direction substantially perpendicular to the longitudinal axis of the capillary wick and directs the airflow out of the capillary wick in a substantially direction parallel to the longitudinal axis of the capillary wick. Preferably, the smoking system comprises an elongated housing and the longitudinal axis of the capillary wick and the longitudinal axis of the housing is substantially parallel. In a second embodiment, the capillary wick is elongated and the removable insert directs the airflow to the capillary wick in a direction substantially perpendicular to the longitudinal axis of the capillary wick and directs the airflow out of the capillary wick in a subsurface direction. substantially perpendicular to the longitudinal axis of the capillary wick. In this case, the air flow to the capillary wick can be substantially perpendicular to the air flow out of the capillary wick. Alternatively, the airflow to the capillary wick can be substantially in the same direction as the airflow out of the capillary wick. Again, preferably, the smoking system comprises an elongated housing and the longitudinal axis of the capillary wick and the longitudinal axis of the housing is substantially parallel.
[0024] Preferably, at least one of the removable inserts comprises holes for channeling the air flow in it. The holes can be formed at the insertion by machining or, alternatively, by injection molding.
[0025] In one embodiment, at least one of the removable inserts is downstream from the capillary wick and comprises a pendulum to hold larger aerosol particles. Larger aerosol particles can be those aerosol particles that have a diameter greater than about 1.5 microns. Alternatively, larger aerosol particles can be those aerosol particles that have a diameter greater than about 1.0 micro meters. Alternatively, larger aerosol particles can include those aerosol particles having other sizes. The greater inertia of the larger aerosol particles means that if the airflow route includes a sharp change in direction, the larger aerosol particles may not be able to change the direction quickly enough to remain in the airflow route and may , instead of being held by the pendulum. The pendulum is preferably positioned to take advantage of the increased thrust of the larger aerosol particles.
[0026] For example, the removable insert may include a plate positioned downstream of the capillary wick to hold larger aerosol particles that come in contact with the plate. The plate can be positioned substantially perpendicular to the air flow path. The position of the pendulum, for example, relative to the capillary wick and heater and relative to the chamber, will affect the size and number of particles that are trapped.
[0027] If the smoking system comprises a pendulum, at least a guide may include an acceleration nozzle to direct the aerosol towards the pendulum. The nozzle can define a decrease in the cross-sectional area of the airflow route in order to accelerate the aerosol for the pendulum. Larger aerosol particles become trapped in the pendulum, while smaller aerosol particles can deviate around the pendulum in the flow path.
[0028] The one or more removable inserts can contain any of the liquid storage portion, the capillary wick and the heater. If a removable insert contains the liquid storage portion, the capillary wick and the heater, those parts of the smoking system can be removable from the housing as a single component. This can be useful for refilling or replacing the liquid storage portion, for example.
[0029] The guides can be provided by additional components positioned in the flow route. For example, the smoking system can also comprise pins, grids, perforated tubes, or any other component that can affect the flow path.
[0030] In one embodiment, the capillary wick is elongated and the guides are configured to channel the air flow upstream of the capillary wick in a direction substantially parallel to the longitudinal axis of the capillary wick. In this embodiment, the smoking system can be lengthened in shape, with the longitudinal axis of the capillary wick being substantially parallel to the longitudinal axis of the smoking system.
[0031] In one embodiment, the capillary wick is elongated and the guides are configured to channel the air flow downstream of the capillary wick in a direction substantially parallel to the longitudinal axis of the capillary wick. In this embodiment, the smoking system can be lengthened in shape, with the longitudinal axis of the capillary wick being substantially parallel to the longitudinal axis of the smoking system.
[0032] In one embodiment, the guides are configured to channel the air flow around the capillary wick in a spiral. In this case, air can enter the spiral in a tangential direction. Air can exit the spiral in a tangential direction. In this embodiment, the capillary wick can be elongated in shape and the spiral can have an axis that is substantially the longitudinal axis of the capillary wick. The smoking system can be elongated in shape, with the longitudinal axis of the capillary wick being substantially parallel to the longitudinal axis of the smoking system.
[0033] In one embodiment, the capillary wick is elongated and the guides are configured to channel the air flow to the capillary wick in a direction substantially perpendicular to the longitudinal axis of the capillary wick. In this embodiment, the smoking system can be lengthened in shape, with the longitudinal axis of the capillary wick being substantially parallel to the longitudinal axis of the smoking system.
[0034] Alternatively, the guides can be configured to channel the air flow to the capillary wick in an intermediate direction between the direction of the longitudinal axis of the capillary wick and the direction perpendicular to the longitudinal axis of the capillary wick. That is, the guides can channel the air flow to the capillary wick at a non-90 ° angle to the capillary wick, that is, in a diagonal direction.
[0035] In one embodiment, the capillary wick is elongated and the guides are configured to channel airflow outside the capillary wick in a direction substantially perpendicular to the longitudinal axis of the capillary wick. In this embodiment, the smoking system can be lengthened in shape, with the longitudinal axis of the capillary wick being substantially parallel to the longitudinal axis of the smoking system.
[0036] In one embodiment, the capillary wick is elongated and the guides are configured to channel the airflow out of the capillary wick in a direction substantially parallel to the longitudinal axis of the capillary wick. In this embodiment, the smoking system can be lengthened in shape, with the longitudinal axis of the capillary wick being substantially parallel to the longitudinal axis of the smoking system.
[0037] Alternatively, the guides can be configured to channel the airflow out of the capillary wick in an intermediate direction between the direction of the longitudinal axis of the capillary wick and the direction perpendicular to the longitudinal axis of the capillary wick. That is, the guides can channel the air flow out of the capillary wick at a non-90 ° angle to the capillary wick, that is, in a diagonal direction.
[0038] At least one heater can comprise a single heating element. Alternatively, at least one heater may comprise more than one heating element, for example, two, three, four, five, six or more heating elements. The heating element or heating elements can be arranged appropriately in order to vaporize the liquid more effectively in the capillary wick.
[0039] At least one heater preferably comprises an electric heating element. At least one heater preferably comprises an electrical resistive material. Suitable electrical resistive materials include, but are not limited to: semiconductors such as doped ceramics, electrical ceramic "conductors" (such as, for example, molybdenum disilicide), carbon, graphite, metals, metal alloys and made from materials composed of a ceramic material and a metallic material. Such composite materials may comprise doped or non-doped ceramics. Examples of suitable doped ceramics include doped silicon carbides. Examples of suitable materials include titanium, zirconium, tantalum and metals from the platinum group. Examples of suitable metal alloys include stainless steel, Constantan, nickel-, cobalt-, chromium-, aluminum- titanium- zirconium-, hafnium-, niobium-, molybdenum-, tantalum-, tungsten-, tin-, gallium-, manganese - and alloys containing iron, and super alloys based on nickel, iron, cobalt, stainless steel, Timetal® and alloys based on ferro-manganese-aluminum. Timetal® is a registered trademark of Titanium Metals Corporation, 1999 Broadway Suite 4300, Denver Colorado. In composite materials, the electrical resistive material can optionally be incorporated in encapsulated or coated with an insulating material or vice versa, depending on the energy transfer kinetics and the necessary external physicochemical properties.
[0040] At least one heater can take any suitable shape. For example, at least one heater can take the form of a heating blade. Alternatively, at least one heater can take the form of a coating or substrate having different portions of electrically conductive, or an electrical resistive metal tube. Alternatively, at least one heater can be a heater disk (end) or a combination of a heater disk with heating needles or rods. Alternatively, at least one heater can take the form of an etched metal sheet isolated between two layers of an inert material. In this case, the inert material can comprise Kapton, totally polyamide or mica sheet. Alternatively, at least one heater can take the form of a sheet of material, which can be wrapped around at least the portion of the capillary wick. Alternatively, at least one heater can take the form of an etched metal sheet folded around at least a portion of the capillary wick. The engraved metal sheet may comprise a metal sheet cut by a laser or by an electro-chemical process. The sheet can be made of any suitable material, for example, an alloy based on iron aluminum, an alloy based on iron manganese aluminum or Timetal®. The sheet may be rectangular in shape, or it may have a shaped shape that may form a coil-like structure when wrapped around the capillary wick. Other alternatives include a heating wire or filament, for example, a Ni-Cr, platinum, tungsten or alloy wire.
[0041] In a preferred embodiment, at least one heater comprises a coil of wire at least partially surrounding the capillary wick. In this embodiment, the wire is preferably a metal wire. Even more preferably, the wire is a metal alloy wire. The coil can extend totally or partially along the length of the capillary wick. The coil can extend totally or partially around the circumference of the capillary wick. In a preferred embodiment, the coil is not in contact with the capillary wick. This allows the coil to be heated to heat the capillary wick, but reduces waste by not spraying more liquid than necessary. This also reduces the amount of liquid that condenses on internal walls, thereby reducing cleaning requirements.
[0042] At least one heater can heat the liquid in the capillary wick by means of conduction. The heater can be at least partially in contact with the wick. Alternatively, heating from the heater can be conducted into the liquid by means of a heating conductive element. Alternatively, at least one heater can transfer heat to the incoming ambient air that is drawn through the smoking system during use, which in turn heats the liquid by convection. The ambient air can be heated before passing through the system. Alternatively, ambient air can be drawn through the wick first and then heating.
[0043] In one embodiment, the smoking system is an electric heating system for smoking. In this modality, the smoking system can also comprise a source of electrical energy. Preferably, the source of electrical energy comprises a cell contained in an enclosure. The source of electrical energy can be a lithium-ion battery or one of its variants, for example, the lithium-ion polymer battery. Alternatively, the power source can be a nickel metal hydride battery, a nickel cadmium battery, a lithium maganese battery, a lithium cobalt battery, or a fuel cell. Preferably, the electric smoking heating system is usable by a smoker until the energy in the feed cell is used. Alternatively, the electrical power source may comprise a generating circuit for a portion of the external charge. In this case, preferably the circuit, when loaded, provides power for a predetermined number of blows, after which the circuit must be reconnected to the external loading portion. An example of a suitable circuit is one or more capacitors or rechargeable batteries.
[0044] If the smoking system is an electrical smoking heating system, the smoking system may further comprise an electrical circuit. In one embodiment, the electrical circuit comprises a sensor to detect the air flow indicative of a user taking a breath. The sensor can be an electromechanical device. Alternatively, the sensor can be any of: a mechanical device, an optical device, an opto-mechanical device, a micro electromechanical system (MEMS) base sensor and an acoustic sensor. In this case, preferably, the electrical circuit is arranged to provide a pulse of electrical current to at least one heater when the sensor detects a user taking a breath. Preferably, the time period of the electric current pulse is predefined, depending on the desired amount of liquid to be vaporized. The electrical circuit is preferably programmable for this purpose.
[0045] Alternatively, the electrical circuit may comprise a switch operable manually by a user to initiate a blow. The time period of the electric current pulse is preferably predefined depending on the desired amount of liquid to be vaporized. The electrical circuit is preferably programmable for this purpose.
[0046] In one mode, at least one air inlet comprises two air intakes. Alternatively, there may be three, four, five or more air intakes. Preferably, if there is more than one air inlet, the air inlets are spaced around the housing. In a preferred embodiment, the electrical circuit comprises a sensor to detect the air flow indicative of a user taking a breath, and at least one air inlet upstream of the sensor.
[0047] Preferably, the smoking system still comprises an indicator blow to indicate when at least one heater is activated. In the mode in which the electrical circuit comprises a sensor to detect the air flow indicative of a user taking a breath, the indicator can be activated when the sensor detects air flow indicative of the user taking a breath. In the mode in which the electrical circuit comprises a manually operable switch, the indicator can be activated by the switch.
[0048] The electric smoking heating system may further comprise an atomizer including at least one heater. In addition, for a heating element, the atomizer can include one or more electromechanical elements such as piezoelectric elements. Additionally or alternatively, the atomizer can also include elements that use electrostatic, electromagnetic or pneumatic effects.
[0049] Preferably, the smoking system comprises a housing. The housing may comprise an outer layer and a nozzle. In this case, all components can be contained in any outer layer or in the nozzle. In the case of an electrical smoking heating system, preferably the electrical power source and the electrical circuit are contained in the outer layer. Preferably, the liquid storage portion, the capillary wick, at least one heater and the air outlet are contained in the nozzle. At least one air inlet can be provided in any outer layer or in the nozzle. The guides can be provided on either the outer layer or the nozzle or both the outer layer and the nozzle. Preferably, the nozzle is replaceable. Having an outer layer and a separate nozzle provides a number of advantages. First, if the replaceable nozzle contains at least one heater, the liquid storage portion and the wick, all elements that are potentially in contact with the liquid are changed when the nozzle is replaced. There will be no cross contamination in the outer layer between different nozzles, for example, those using different liquids. Also, if the nozzle is replaced at appropriate intervals, there is little chance that the heater will become clogged with liquid. Preferably, the outer layer and nozzle are arranged to removably lock together when compromised.
[0050] The wrapper can comprise any suitable material or combination of materials. Examples of suitable materials include metals, alloys, plastics or composite materials containing one or more of those materials, or thermoplastics that are suitable for food or pharmaceutical applications, for example, polypropylene, polyether (PEEK) and polyethylene. Preferably, the material is light and not fragile.
[0051] Preferably, the smoking system is portable. The smoking system can be comparable in size to a conventional cigar or cigarette.
[0052] According to a second aspect of the invention, a smoking system is provided comprising: a capillary wick for maintaining the liquid; at least one air inlet, at least one air outlet and a chamber between the air inlet and air outlet, the air inlet, the air outlet and the chamber being arranged in order to define an air flow route from the air inlet to the air outlet through the capillary wick in order to conduct the aerosol formed from the liquid to the air outlet; and at least one guide for channeling the air flow in the air flow route, in order to control particle size in the aerosol.
[0053] In this case, the smoking system may comprise an atomizer to create the aerosol. The atomizer may include one or more electromechanical elements such as piezoelectric elements. Additionally or alternatively, the atomizer can also include elements or use electrostatic, electromagnetic or pneumatic effects.
[0054] Features described in relation to one aspect of the invention may also be applicable to another aspect of the invention.
[0055] The invention will be further described, by way of example only, with reference to the drawings that follow in which:

[0067] Figures 12a to 12l show an eleventh mode of the smoking system according to the invention.
[0068] Figure 1 shows an example of a smoking system having a liquid storage portion. The smoking system 100 of figure 1 is an electric smoking heating system and comprises a housing 101 having one end of the nozzle 103 and one end of the body 105. At the end of the body, a source of electrical energy in the form is provided battery 107 and electrical circuit in the form of circuit 109 and a puff detection system 111. At the end of the nozzle, a liquid storage portion in the form of a cartridge 113 containing liquid 115, a capillary wick 117 and a filter element is provided. heating in the form of a heating coil 119. One end of the capillary wick 117 extends in the cartridge 113 and the other end of the capillary wick 117 is surrounded by the heating coil 119. The heating coil is connected to the electrical circuit through the connections 121. Housing 101 also includes an air inlet 123, an air outlet 125 at the end of the nozzle and an aerosol chamber forming chamber 127.
[0069] In use, the operation is as follows. The liquid 115 is transferred through the capillary action from the cartridge 113 from the end of the wick 117 which extends in the cartridge to the other end of the wick 117 which is surrounded by the heating coil. When a user calls the device at the air outlet 125, ambient air is drawn through the air inlet 123. In the arrangement in figure 1, the blowing detection system 111 detects the blowing and activates the heating coil 119. Battery 107 provides a power pulse to the heating coil 119 to heat the end of the wick 117 surrounded by the heating coil. The liquid in which the end of the wick 117 is vaporized by the heating coil 119 to create supersaturated steam. At the same time, the liquid being vaporized is replaced by the movement of the liquid still along the wick 117 through the capillary action. (This is sometimes referred to as the "pumping action".) The supersaturated vapor created is mixed with and transported in the air flow from the air inlet 123. In the aerosol forming chamber 127, the vapor condenses to form an aerosol that is transported to outlet 125 and into the user’s mouth.
[0070] In the embodiment of figure 1, circuit 109 and the blowing detection system 111 are preferably programmable. Circuit 109 and blowing detection system 111 can be used to manage the operation of the device. This, in conjunction with the physical design of the electric smoking heating system, can help with controlling the particle size in the aerosol.
[0071] The capillary wick can be made from a variety of porous or capillary materials and preferably has a known, predefined capillarity. Examples include materials based on graphite or ceramics in the form of fibers or sintered powders. Wicks of different porosities can be used to accommodate different liquid physical properties such as density, viscosity, surface tension and vapor pressure. The wick should be adequate so that the required quantities of liquid can be delivered to the heating coil.
[0072] Figure 1 shows an example of a smoking system that can be used with the present invention. Many other examples are usable with the invention, however. For example, the smoking system does not need to be operated electrically. For example, additional air intakes can be provided, for example, circumferential spacing around the enclosure. For example, a breath detection system does not need to be provided. Instead, the system could operate through manual operation, for example, the user operating a switch when a blow is taken. For example, the housing could comprise an outer layer and a separable nozzle. For example, the overall shape and size of the wrapper could be changed. For example, the liquid cartridge can be omitted and the capillary wick could simply be preloaded with liquid before use. Other variations are, of course, possible.
[0073] A number of embodiments of the invention will now be described, based on the example shown in figure 1. Components shown in figure 1 are not indicated again, in order to simplify the drawings. In addition, the blowing detection system 111 and connections 121 is not shown, again for simplicity. Note that figure 1 and the following figures 2a to 11l are schematic in nature. In particular, the components shown are not for any scale individually or relative to another.
[0074] Figures 2a, 2b and 2c show a first embodiment of the smoking system according to the invention. Figure 2a shows a cross-sectional view of the nozzle end of the first embodiment of the smoking system 200. In figure 2a, the smoking system 200 includes guides for channeling the air flow within the smoking system. In this embodiment, the guides are provided on the removable insert 201 and on the inner walls of the housing 203. The air flow is shown by dotted arrows.
[0075] The removable insert 201 extends across the entire cross section of the smoking system 200 and includes channels 205 for channeling the air flow between the air inlet and the capillary wick and heating coil. In this embodiment, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 201, although this need not be the case. The tapered channels 205 inward to direct the air flow generally in the direction of the longitudinal axis of the housing, but diagonally towards the capillary wick and heating coil.
[0076] In addition, the inner walls of the 203 housing is formed to form the aerosol forming the chamber 202 and provides guides for channeling the air and aerosol flow between the capillary wick and heating coil and the air outlet, through the aerosol forming the chamber 202. In this embodiment, the inner walls of the housing 203 are funneled towards the air outlet and thus direct the air and aerosol flow substantially in the direction of the longitudinal axis of the housing.
[0077] Figures 2b and 2c are cross sections along line A-A of figure 2a. Figures 2b and 2c show two alternative arrangements for channels 205 in removable insert 201. Although the cross section of the device is shown as circular in figures 2a, 2b and 2c, this need not be the case. In figure 2b, the entrance of each channel is circumferentially aligned with the exit of the channel. In figure 2c, channels 205 are twisted around the housing axis. That is, the entrance of each channel is displaced circumferentially with respect to the exit of the channel. Preferably, insert 201 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, in order to ensure that the insert is correctly positioned within the housing. smoking system. This can be important for electrical connections to the heating coil, for example.
[0078] The embodiment shown in figures 2a, 2b and 2c provides an axially substantial inlet air flow from the air inlet to the capillary wick and heating coil and an axially substantial outward air flow from from the capillary wick and the heating coil to the air outlet. Airflow management in this way has been found to improve aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The guides provided by inserting 201 the air flow channel in order to concentrate the air flow in the wick and heating element and in order to increase the turbulence. This decreases the size of the aerosol particle inhaled by a user. The guides provided by the internal walls of the 203 housing reduce the volume of the aerosol by forming the chamber 202 in the smoking system and therefore improve the flow of the aerosol to the air outlet. This improves the smoking experience. The arrangement of figure 2c encourages a rotated air flow to further improve aerosol formation.
[0079] A number of variations are possible in the smoking system of figures 2a, 2b and 2c. First, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (insert 201, as shown) or alternatively as an integral part of the housing or as a combination of both. Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the housing (housing formed by internal walls 203, as shown) or as a combination of both. Any number of channels 205 can be formed at insertion 201. The channels can be uniformly or non-uniformly circumferentially distributed around the insert. The channels can be arranged as several lines forming circles of different diameters. The channels can have a constant cross-sectional shape and area along their length, or a cross-sectional shape can vary along the length. Channels can include some channels having different cross-sectional shapes and areas from others. The channels can be formed on insertion by machining. Alternatively, the insert can be formed together with the channels through injection molding. The channels can be formed at any angle appropriate to the longitudinal axis of the enclosure. The inner walls of the housing 203 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber 202 within the smoking system.
[0080] Figures 3a and 3b show a second embodiment of the smoking system according to the invention. Figure 3a shows a cross-sectional view of the nozzle end of the second embodiment of the smoking system 250. In figure 3a, the smoking system 250 includes guides for channeling the air flow within the smoking system. In this embodiment, the guides are provided on the removable insert 251 and on the inner walls of the housing 253. The air flow is shown by dotted arrows.
[0081] The removable insert 251 extends across the entire cross section of the smoking system 250 and includes primary channels 255 and secondary channels 257 to channel the air flow between the air inlet and the capillary wick and heating coil. In this embodiment, channels 255, 257 are substantially tubular holes in the insert 251. In this embodiment, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 251, although this need not be the case. Like channels 205 shown in figures 2a, 2b and 2c, primary channels 255 in figures 3a and 3b tapered to direct the airflow inwardly generally in the direction of the longitudinal axis of the wrapper, but diagonally to the capillary wick and heating coil. In figures 3a and 3b, the secondary channels 257 extend generally parallel to the longitudinal axis of the housing. Secondary channels 257 are closest to the outside of the smoking system. This creates a secondary air flow that substantially exceeds the wick. This secondary air flow therefore carries fewer drops of aerosol than the air flow that is close to the wick. This secondary, relatively dry, airflow close to the inner walls can reduce the amount of condensation forming on the inner walls. This can reduce leakage.
[0082] In addition, the inner walls of the casing 253 are formed to form the aerosol forming the chamber 252 and provide guides for channeling the air and aerosol flow between the capillary wick and heating coil and the air outlet, through the aerosol forming the chamber 252. In this embodiment, the inner walls of the casing 253 are tapered towards the air outlet and thus direct the air and flow of the aerosol substantially in the direction of the longitudinal axis of the casing.
[0083] Figure 3b is a cross section along line A '' - A '' 'of figure 3a. Although the cross section of the device is shown as circular in figures 3a and 3b, this need not be the case. Referring to Figure 3b, the insert 251 comprises primary channels 255 and secondary channels 257. In figure 3b, the input of each primary channel 255 is circumferentially aligned with the outlet of the channel, as in figure 2a. However, primary channels 255 can be twisted around the housing axis, as in figure 2b. In figure 3b, the secondary channels 257 extend in the direction of the longitudinal axis of the housing. However, one or more of the secondary channels 257 can be angled to the longitudinal axis of the housing. Secondary channels 257 are closer to the enclosure than primary channels 255. Thus, the airflow through secondary channels 257 is outward from the airflow through primary channels 255. In figure 3b, the entry of each secondary channel 257 is circumferentially aligned with the outlet of the channel. However, the secondary channels 257 can alternatively be twisted around the axis of the housing. Preferably, insert 251 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned inside the smoking system. This can be important for electrical connections to the heating coil, for example.
[0084] The modality shown in figures 3a and 3b provides an axially substantial inlet air flow from the air inlet to the capillary wick and heating coil and an axially substantial outward air flow from the wick capillary and heating coil for the air outlet. In addition, the embodiment shown in figures 3a and 3b provides an additional axially substantial inlet air flow from the air inlet to the capillary wick and heating coil and an additional axially substantial outward air flow from the capillary wick and heating coil for the air outlet. The additional air flow is to the outside of the smoking system. Because the additional air flow is less close to the heating coil, it tends to carry less e-rosol. Thus, it can contribute to improving the characteristics of the aerosol and reducing condensation. Airflow management in this way has been found to improve aerosol formation within the smoking system. The guides provided by inserting the airflow channel 251 in order to concentrate airflow in the wick and heating element and in order to increase the turbulence. This decreases the size of the aerosol particle inhaled by a user. It also provides an additional air flow that can reduce condensation forming in the smoking system. The guides provided by the inner walls of the housing 253 reduce the volume of the aerosol forming the chamber 252 in the smoking system and therefore improve the flow of the aerosol to the air outlet. This improves the smoking experience.
[0085] A number of variations are possible in the smoking system of figures 3a and 3b. First, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (insert 251, as shown) or alternatively as an integral part of the housing or as a combination of both. Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the wrapper (wrapper formed inner walls 253, as shown) or as a combination of both. Any number of channels 255, 257 can be formed at insertion 201. The channels can be uniformly or non-uniformly distributed circumferentially around the insertion. The channels can be arranged as several lines forming circles of different diameters. The channels can have a constant cross-sectional shape and area along their length, or the cross-sectional shape can vary along the length. The channels can include some channels having different shapes of the cross section and areas from the others. The channels can be formed on insertion by machining. Alternatively, the insert can be formed together with the channels through injection molding. The channels can be formed at any angle appropriate to the longitudinal axis of the enclosure. The inner walls of the casing 253 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber 252 within the smoking system.
[0086] Figures 4a and 4b show a third embodiment of the smoking system according to the invention. Figure 4a shows a cross-sectional view of the nozzle end of the second embodiment of the smoking system 300. In figure 4a, the smoking system 300 includes guides for channeling the air flow within the smoking system. In this embodiment, the guides are provided on the removable insert 301 and on the inner walls of the enclosure 303. The air flow is shown by dotted arrows.
[0087] Like the removable insert 201 in figures 2a, 2b and 2c, removable insert 301 extends across the entire cross section of the smoking system. However, in this embodiment, it also extends upstream than insert 201. Removable insert 301 includes channels 305 for channeling the air flow between the air inlet and the capillary wick and heating coil. The channels 305 extend in the direction of the longitudinal axis of the enclosure at its upstream end, then tapered into its downstream end. The channels 305 direct the air flow generally in the direction of the longitudinal axis of the casing initially, then diagonally to the capillary wick and heating coil. In this embodiment, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 301, although this need not be the case.
[0088] In addition, the inner walls of the casing 303 are formed to form the aerosol forming the chamber 302 and to provide guides for channeling the air and flow of the aerosol between the capillary wick and heating coil and the air outlet, through the aerosol forming the chamber 302. In this embodiment, the inner walls of the casing 303 are tapered towards the air outlet and thus direct the air and flow of the aerosol substantially in the direction of the longitudinal axis of the casing.
[0089] Figure 4b is a cross section along line B-B of figure 4a. Although the cross section of the device is shown to be circular in figures 4a and 4b, this need not be the case. Referring to figure 4b, insert 301 comprises channels 305. Around the circumference of insert 301 there are several contact zones 307 for contacting the interior of the enclosure. That is, the channels are formed by mounting the insert in the housing. Preferably, insert 301 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, in order to ensure that the insert is correctly positioned within of the smoking system. This can be important for electrical connections to the heating coil, for example.
[0090] The embodiment shown in figures 4a and 4b provides an axially substantial inlet air flow from the air inlet to the capillary wick and heating coil and an axially substantial outward air flow from the wick capillary and heating coil for the air outlet. Airflow management in this way has been found to improve aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The guides provided by inserting 301 channel the air flow in order to concentrate air flow in the wick and heating element and in order to increase the turbulence. This decreases the size of the aerosol particle inhaled by a user. The guides provided by the inner walls of the casing 303 reduce the volume of the aerosol forming the chamber 302 in the smoking system and therefore improve the flow of the aerosol to the air outlet. This improves the smoking experience.
[0091] A number of variations are possible in the smoking system of figures 4a and 4b. First, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (insert 301, as shown) or alternatively as an integral part of the assembly or as a combination of both. Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the assembly (inner shell walls 303, as shown) or as a combination of both. Any number of channels 305 can be formed at insertion 301. The channels can be uniformly or non-uniformly distributed circumferentially around the insertion. The channels can be arranged as several lines forming circles of different diameters. The channels can have a constant cross-sectional shape and area along their length, or the cross-sectional shape can vary along the length. Channels can include some channels having different cross-sectional shapes and areas from others. The channels can be formed on insertion by machining. Alternatively, the insert can be formed together with the channels through injection molding. The channels can be formed at any angle appropriate to the longitudinal axis of the enclosure. As in figure 2c, the channels can be twisted around the housing axis in order to encourage a rotated air flow. The inner walls of the casing 303 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber 302 within the smoking system.
[0092] Figure 5 shows a fourth embodiment of the fuel system according to the invention. Figure 5 shows a cross-sectional view of the nozzle end of the third embodiment of the smoking system 400. In figure 5, the smoking system 400 includes guides for channeling the air flow within the smoking system. In this mode, the guides are provided through the removable insert 401, through the inner walls of the housing 403 and the pendulum 405. The air flow is shown by dotted arrows.
[0093] The removable insert 401 is similar to the removable insert 301 shown in figures 4a and 4b and extends across the entire cross section of the smoking system 400. The removable insert 401 includes channels 407 for channeling the air flow between the air inlet and capillary wick and heating coil. The channels 407 extend in the direction of the longitudinal axis of the enclosure at its upstream end, then tapered into its downstream end. The 407 channels direct the air flow generally in the direction of the longitudinal axis of the casing initially, then diagonally towards the capillary wick and heating coil. In this embodiment, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 401, although this need not be the case. Preferably, insert 401 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned within the housing. smoking system. This can be important for electrical connections to the heating coil, for example. The insert could alternatively take the shape shown in figure 2a or another suitable shape.
[0094] In addition, the inner walls of the casing 403 and pendulum 405 provide guides for channeling the flow of the aerosol between the capillary wick and heating coil and the air outlet. The inner walls of the housing 403 and pendulum 405 also form the aerosol forming the chamber 402. In this embodiment, the inner walls of the housing are formed in order to direct the flow away from the heating coil in the radial direction, that is, substantially perpendicular to the longitudinal axis of the enclosure. Pendulum 405 comprises a removable insert that can be positioned in the center of the device, supported by the walls of the enclosure (see dotted lines). Pendulum 405 allows larger aerosol particles to be attached to its upstream side. This produces a filtering effect and reduces the average particle size. This is shown schematically in figure 5. Then, the inner walls of the housing 403 and pendulum 405 direct the air flow towards the air outlet.
[0095] The embodiment shown in figure 5 provides an axially substantial inlet air flow from the air inlet to the capillary wick and heating coil and an air flow radially substantially downstream from the capillary wick and heating coil . It has been found that managing airflow in this way improves aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The guides provided by the insertion 401 of the air flow channel in order to concentrate the air flow in the wick and heating element and in order to increase the turbulence. This decreases the size of the aerosol particle inhaled by a user. The guides provided by the inner walls of the 403 housing and pendulum allow larger aerosol particles to be trapped and prevented from exiting through the air outlet. The arrangement allows the capillary wick and heating coil to be supplied with fresh, unsaturated air in order to decrease the particle size of the aerosol. This improves the smoking experience.
[0096] A number of variations are possible in the smoking system in figure 5. First, although the cross section of the device is shown as circular in figure 5, this need not be the case. Second, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (insertion 401, as shown) or alternatively as an integral part of the housing or as a combination of both. Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure or as a combination of both (inner enclosure wall 403 combined with removable pendulum 405, as shown). Any number of channels 407 can be formed at insertion 401. The channels can be uniformly or non-uniformly distributed circumferentially around the insertion. The channels can be arranged on the different lines forming circles of different diameters. The channels can have a constant cross-sectional shape and area along their length, or the cross-sectional shape can vary along the length. Channels can include some channels having different cross-sectional shapes and areas from others. The channels can be formed on insertion by machining. Alternatively, the insert can be formed with the channels through injection molding. The channels can be formed at any angle appropriate to the longitudinal axis of the enclosure. As in figure 2c, the channels can be twisted around the housing axis in order to encourage a rotated air flow. The inner walls of the casing 403 and pendulum 405 can be formed and adequate size for the desired volume and shape of the aerosol forming the chamber 402 within the smoking system. The pendulum 405 can be formed in any suitable shape and is preferably designed in conjunction with the housing formed by inner walls 403, in order to channel the air and aerosol flow as desired.
[0097] Figures 6a and 6b show a fifth embodiment of the smoking system according to the invention. Figure 6a shows a cross-sectional view of the nozzle end of the fourth embodiment of the smoking system 500. In figure 6a, the smoking system 500 includes guides for channeling the air flow within the smoking system. In this embodiment, the guides are provided by the removable insert 501, the inner walls of the housing 503 and the pendulum 505.
[0098] The removable insert 501 is similar to the removable insert 201 shown in figures 2a, 2b and 2c and extends through the entire cross section of the smoking system 500 and includes channels 507 for channeling the air flow between the inlet air and the capillary wick and heating coil. In this embodiment, the liquid cartridge, the capillary wick and heating coil all form parts of the removable insert 501, although this need not be the case. The conical channels 507 inward to direct the air flow generally towards the longitudinal axis of the housing, but diagonally towards the capillary wick and heating coil. Preferably, insert 501 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned inside the smoking system. This can be important for electrical connections to the heating coil, for example. The insert could alternatively take the shape shown in figures 4a and 5 or another suitable shape.
[0099] In addition, the inner wall wrappers 503 are tapered inward to form the aerosol forming the chamber 502. The inner walls of the wrapper 503 together with the pendulum 505 provide guides for channeling the flow of the aerosol between the capillary wick and coil heating and the air outlet. In this embodiment, the inner walls of the casing 503 are formed in order to form a nozzle to direct and accelerate the air flow substantially in the axial direction.
[00100] Pendulum 505 is located directly downstream of the aerosol forming the chamber. Figure 6b is a cross section along line C-C of figure 6a. The 505 pendulum acts to spread larger aerosol particles and therefore provides a filtering effect. Pendulum 505 comprises a plate 505a that can be positioned in the center of the enclosure, supported on the walls of the enclosure by supports 505b. The plate 505a acts to stop the larger aerosol particles from escaping the aerosol forming the chamber 502.
[00101] The modality shown in figures 6a and 6b provides an accelerated, axially directed airflow substantially downstream of the capillary wick and heating coil. Airflow management in this way has been found to improve aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The guides provided by the insert 501 channel the air flow in order to concentrate the air flow in the wick and heating element and in order to increase the turbulence. This decreases the size of the aerosol particle inhaled by a user. The shape of the conical nozzle provided by the inner walls of the casing 503 accelerates the aerosol downstream to the pendulum 505 and the plate 505a of the pendulum 505 bars the larger aerosol particles to prevent them from escaping through the air outlet. The arrangement allows the capillary wick and heating coil to be supplied with fresh, unsaturated air in order to decrease the particle size of the aerosol. It also allows any larger aerosol particles that form to be filtered out of the stream. This improves the smoking experience.
[00102] A number of variations are possible in the smoking system of figures 6a and 6b. First, even though the cross section of the device is shown as circular in figures 6a and 6b, this need not be the case. Second, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (insert 501, as shown) or alternatively as an integral part of the housing or as a combination of both. Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure or as a combination of both (inner enclosure wall 503 combined with removable pendulum 505, as shown). Any number of channels 507 can be formed at insertion 501. The channels can be uniformly or non-uniformly distributed circumferentially around the insertion. The channels can be arranged as several lines forming circles of different diameters. The channels can have a constant cross-sectional shape and area along their length, or the cross-sectional shape can vary along the length. Channels can include some channels having different cross-sectional shapes and areas from others. The channels 507 can be twisted around the housing axis to provide a rotated air flow. The channels can be formed on insertion by machining. Alternatively, the insert can be formed together with the channels through injection molding. The channels can be formed at any angle appropriate to the longitudinal axis of the enclosure.
[00103] The inner walls of the casing 503 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber 502 within the smoking system and for the desired acceleration of the aerosol for the pendulum 505. The pendulum can be formed by machining or injection molding. The shape and size of the pendulum plate 505a can be varied. The distance between the downstream end of the aerosol forming the chamber 502 and the pendulum plate can be varied.
[00104] Figures 7a to 7e shows a sixth embodiment of the smoking system according to the invention. Figures 7a to 7e each show a cross-sectional view of the nozzle end of the fifth embodiment of the smoking system. In each of figures 7a to 7e, the smoking system includes guides for channeling the air flow within the smoking system. The air flow is shown by dotted arrows.
[00105] Figure 7a shows a first arrangement of the smoking system 600. In figure 7a, the guides are provided by the removable insert 601 and the inner walls of the housing 603. The removable insert 601 extends only through the center of the smoking system. 600, thus directing the air flow between the air inlet and the capillary wick and heating coil to the outside of the circumference of the device. The removable insert 601 is formed so that, in the capillary wick and heating coil, the air flow is directed towards the capillary wick and heating coil in a substantially radial direction, that is, substantially perpendicular to the longitudinal axis of the housing. In figures 7a to 7e, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 601, although this need not be the case.
[00106] In addition, the inner walls of the 603 housing provide guides for channeling the air and aerosol flow between the capillary wick and heating coil and the air outlet. The inner walls of the casing 603 also define the aerosol forming the chamber 602. In this embodiment, the inner walls of the casing 603 are formed in order to direct the air and flow of the aerosol substantially in the direction of the longitudinal axis of the casing.
[00107] Figure 7b shows a second arrangement of the 600 'smoking system. The arrangement shown in figure 7b is identical to that shown in figure 7a except that an additional insert 605 is provided in the smoking system 600 'of figure 7b. The additional insert 605 provides additional guides for directing the air flow. Insert 605 is a ribbed insert surrounding the capillary wick and heating coil. It is formed in order to direct the air flow to the capillary wick and heating coil in a substantially radial direction, that is, substantially perpendicular to the longitudinal axis of the envelope.
[00108] Figure 7c shows a third arrangement of the 600 ’’ smoking system. The arrangement shown in figure 7c is identical to that shown in figure 7a except that an additional insert 607 is provided in the smoking system 600 '' of figure 7c. Additional insert 607 provides additional guides for directing airflow. Insert 607 is a grid insert comprising a tube having a number of longitudinally spaced holes. The insert 607 surrounds the capillary wick and heating coil and directs the air flow through the holes in the grid and towards the capillary wick and heating coil in a substantially radial direction, that is, substantially perpendicular to the longitudinal axis of the housing.
[00109] Figure 7d shows a fourth layout of the 600 ’’ ’smoking system. The arrangement shown in figure 7d is identical to that shown in figure 7a except that an additional insert 609 is provided in the smoking system 600 '' '' of figure 7d. Additional insert 609 provides additional guides for directing airflow. Insert 609 is a grooved insert comprising a solid cylindrical tube having a number of channels formed in the radial direction. The insert 609 surrounds the capillary wick and heating coil and directs the air flow through the radial channels and towards the capillary wick and heating coil in a substantially radial direction, that is, substantially perpendicular to the longitudinal axis of the housing.
[00110] Figure 7e shows a fifth layout of the 600 ’’ ’’ ’smoking system. The arrangement shown in figure 7e is identical to that shown in figure 7a except that an additional insert 611 is provided in the smoking system 600 '' '' '' of figure 7e. The additional 611 insert provides additional guides for directing the air flow. Insert 611 is a grooved insert comprising a solid tapered tube having a number of channels formed in the radial direction. The insert 611 surrounds the capillary wick and heating coil and directs the air flow through the radial channels and towards the capillary wick and heating coil in a substantially radial direction, that is, substantially perpendicular to the longitudinal axis of the housing.
[00111] The modalities shown in figure 7a to 7e provide an air flow directed radially substantially towards the capillary wick and heating coil and an air flow and aerosol directed radially substantially downstream of the capillary wick and heating coil. Airflow management in this way has been found to improve aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The guides provided by the insert 601, and the additional insert 605, 607, 609, 611 are shown, channel the air flow as to direct the air flow to the capillary wick and heating coil in a substantially radial direction. This provides the capillary wick and heating coil with fresh, unsaturated air, which decreases the size of the aerosol particle inhaled by a user. The guides provided by the inner walls of the housing 603 reduce the volume of the cavity in the smoking system and therefore improve aerosol flow to the air outlet. This improves the smoking experience.
[00112] A number of variations are possible in the smoking system of figures 7a to 7e. First, even though the cross section of the device is shown as circular in figures 7a to 7e, this need not be the case. Second, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (inserts 601, 605, 607, 609 and 611, as shown) or alternatively as an integral part of the housing or as a combination of both. Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure (inner enclosure walls 603, as shown) or as a combination of both. The insert 601 is shown without channels, although longitudinal channels to the outside of the insert can be provided. In addition, if channels are provided, the insert can extend across the entire cross section of the housing. Any channel configuration can be provided. The channels can be twisted around the housing axis in order to encourage a swirling air flow. The channels in the inserts 601, 605, 609, 611 and the holes in the insert 607 can be formed by machining. Alter-natively, the insertion can be formed with channels or holes already formed, through injection molding. Any number of holes or channels can be formed in inserts 605, 607, 609, 611. Preferably, insert 601 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) inside the enclosure walls to ensure that the insert is correctly positioned within the smoking system. This can be important for electrical connections to the heating coil, for example. The inserts 605, 607, 609, 611 can also be provided with such a locating or protruding pin. The inner walls of the casing 603 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber within the smoking system.
[00113] Figures 8a to 8c shows a seventh embodiment of the smoking system according to the invention. Figure 8a shows a cross-sectional view of the nozzle end of the sixth embodiment of the smoking system 700. In figure 8a, the smoking system 700 includes guides for channeling the air flow within the smoking system. In this embodiment, the guides are provided by the removable insert 701 and the walls of the enclosure 703. The air flow is shown by dotted arrows.
[00114] The removable insert 701 is similar to the removable insert 601 shown in figures 7a to 7e and extends only through the center of the smoking system 700, thus directing the air flow between the air inlet and the capillary wick and coil heating element to the outside of the circumference of the device. In figure 8a, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 701, although this need not be the case.
[00115] In addition, the inner walls of the 703 housing provide guides for channeling the flow of the aerosol into the capillary wick and heating coil, and between the capillary wick and heating coil and the air outlet. The inner walls of the wrapper 703 also define the aerosol forming the chamber 702. In this embodiment, the walls of the wrapper 703 are formed so that the inlet of the air flow to the capillary wick and heating coil is directed in an upstream channel 705 tangential for the circular cross section of the device and the circular cross section of the aerosol forming the chamber 702.
[00116] Figure 8b is a cross section along line D-D of figure 8a. In figure 8a the inner walls of the casing 703 are formed so that the channel 705 provides an air flow to the capillary wick and heating coil that is in the tangential direction. This produces a spiral airflow around the capillary wick and heating coil for the air outlet.
[00117] Figure 8c is a cross section also along the D-D line showing an alternative arrangement, in which two channels 705, 705 ’for the capillary wick and heating coil are provided. Both channels direct the air flow in the tangential direction and together it produces a spiral air flow around the capillary wick and the heating coil to the air outlet. Additional upstream tangential channels could also be provided.
[00118] The embodiment shown in figures 8a, 8b and 8c provides an air flow directed tangentially substantially to the capillary wick and heating coil and a spiral air flow substantially around the capillary wick and the heating coil and from from the capillary wick and heating coil to the air outlet. It has been found that managing airflow in this way improves aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The formed inner walls 703 of the housing, together with the insert 701 directs the air flow in order to supply fresh, unsaturated air to the capillary wick and heating coil. Once the airflow targets the capillary wick and heating coil, they are immediately evacuated to the air outlet. This decreases the size of the aerosol particle inhaled by a user. The spiral airflow around the capillary wick and heating coil increases turbulence and reduces the particle size of the aerosol. The size of the tangential channel or channels and their relative position to the longitudinal axis of the influence of the airflow device around the capillary wick and heating coil and therefore the characteristics of the aerosol. In addition, the centrifugal forces in the spiral airflow can allow larger aerosol particles to impact and be trapped on the outer walls of the aerosol forming the chamber 702. This is shown schematically in figure 8a. The arrangement of figure 8c further improves the formation of the aerosol by providing a better distribution of the flow within the aerosol forming the chamber.
[00119] A number of variations are possible in the smoking system of figures 8a, 8b and 8c. The cross section of the device is preferably circular, so that channel 705 can define the tangential air flow. However, other shapes of the cross section are also possible, since some species of the upstream tangential channel can be defined. More than one air inlet (in the enclosure) can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure or as a combination of both (removable insert 701 combined with enclosure-shaped walls 703, as shown). Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the housing (inner walls in the form of housing 703, as shown) or as a combination of both. Insert 701 is shown without channels, although longitudinal channels to the outside of insert 701 can be provided. In addition, if channels are provided, the insert can extend across the entire cross section of the housing. Any channel configuration can be provided. The channels can be twisted around the housing axis in order to encourage a swirling air flow. Any channels in insert 701 can be formed by machining. Alternatively, the insert can be formed with channels or holes already formed, through injection molding. Insert 701 may comprise a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned within the smoke. This can be important for electrical connections to the heating coil, for example. The inner walls of the casing 703 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber within the smoking system. This affects the flow of the spiral aerosol around the capillary wick and the heating coil and therefore the characteristics of the aerosol. The tangential channels 705, 705 'can be positioned at any height along the capillary wick and can have any suitable cross section. Figures 9a to 9c show an eighth embodiment of the smoking system according to the invention. Figure 9a shows a cross-sectional view of the nozzle end of the seventh embodiment of the smoking system 800. In figure 9a, the smoking system 800 includes guides for channeling the air flow within the smoking system. In this mode, the guides are provided by the removable insert 801, in the walls in the form of an enclosure 803 and by the pendulum 807. The air flow is shown by dotted arrows.
[00120] Removable insert 801 is similar to removable insert 601 shown in figures 7a to 7e and removable insert 701 shown in figure 8a and extends only through the center of the smoking system 800, thus directing the air flow between the inlet of air and the capillary wick and heating coil to the outside of the circumference of the device. In figure 9a, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 801, although this need not be the case.
[00121] In addition, the inner walls of the 803 enclosure provide guides for channeling the air flow to the capillary wick and heating coil. In this embodiment, the walls of the enclosure 803 are formed so that the airflow inlet to the capillary wick and heating coil is directed through an upstream channel 805 tangential to the circular cross section of the device and the circular cross section of the aerosol forming the 802 camera.
[00122] In addition, an 807 pendulum is provided at the end downstream of the capillary wick and heating coil. The pendulum provides guides for channeling the air flow away from the capillary wick and heating coil and to the air outlet. The pendulum 807 in conjunction with the inner walls of the enclosure, also defines the aerosol forming the 802 chamber. The air flow is directed away from the capillary wick and heating coil in the radial direction in the downstream channel 809, that is, substantially perpendicular to the longitudinal axis of the enclosure. Pendulum 807 allows larger aerosol particles to be trapped on its upstream side. This is shown schematically in figure 9a. The inner walls of the casing 803 can be tapered to direct the air flow to the air outlet, although this is not shown in figure 9a.
[00123] Figure 9b is a cross section along the EE line of figure 9a showing upstream channel 805. The walls of housing 803 are formed so that channel 805 provides an air flow to the capillary wick and heating coil that is in the tangential direction. This produces a spiral airflow around the capillary wick and heating coil.
[00124] Figure 9c is a cross section along the FF line of figure 9a showing the downstream channel 809. The pendulum 807 and walls of the enclosure 803 cooperate so that the channels 809 provide an air flow away from the capillary wick and heating coil that is in the radial direction substantially. That is, downstream of the spiral airflow around the capillary wick and heating coil, the aerosol flow is directed in the radial direction and then towards the air outlet.
[00125] The embodiment shown in figures 9a, 9b and 9c provides an air flow directed tangentially substantially to the capillary wick and heating coil, a spiral air flow substantially around the capillary wick and heating coil and a flow of air directed radially substantially away from the capillary wick and heating coil to the air outlet. It has been found that managing airflow in this way improves aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The internal walls of the casing 803 formed, together with the insert 801, direct the air flow in order to supply fresh, unsaturated air to the capillary wick and heating coil. This decreases the size of the aerosol particle inhaled by a user. The spiral airflow around the capillary wick and heating coil increases turbulence and reduces aerosol particle size. Larger aerosol particles can also become trapped in the internal walls of the aerosol forming the 802 chamber due to centrifugal forces. This is shown schematically in figure 9a. The radially directed outlet airflow means that once the airflow is aimed at the capillary wick and heating coil they are immediately evacuated to the air outlet. Additional upstream tangential channels can be provided (as in figure 8c, for example) which can provide a better flow distribution within the aerosol forming the chamber. The size of the tangential channel or channels and their relative position to the longitudinal axis of the device influences the air flow around the capillary wick and heating coil and, for this reason, the characteristics of the aerosol. In addition, the pendulum can allow larger aerosol particles to impact your upstream wall. This is shown schematically in figure 9a.
[00126] A number of variations are possible in the smoking system of figures 9a, 9b and 9c. The cross section of the device is preferably circular, so that channel 805 can define a tangential air flow. However, other shapes of the cross section are also possible, since an upstream tangential channel can be defined. More than one air inlet (in the enclosure) can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure or as a combination of both (removable insert 801 combined with enclosure-shaped walls 803, as shown) . Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure or as a combination of both (enclosure-shaped walls intern 803 combined with pendulum 807, as shown). Insert 801 is shown without channels, although longitudinal channels to the outside of insert 801 can be provided. In addition, if channels are provided, the insert can extend across the entire cross section of the housing. Any channel configuration can be provided. The channels can be twisted around the housing axis in order to encourage a swirling air flow. Any channels in insert 801 can be formed by machining. Alternatively, the insert can be formed with channels or holes already formed, through injection molding. Insert 801 may comprise a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned within the housing. smoking system. This is important for electrical connections to the heating coil, for example. The inner walls of the casing 803 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber within the smoking system. This affects the flow of the aerosol in a spiral around the capillary wick and heating coil and therefore the characteristics of the aerosol. The tangential channel 805 can be positioned at any time along the capillary wick and can have any suitable cross section. Any number of 809 radial channels can be provided. The pendulum 807 can be formed in any suitable shape and is preferably designed in conjunction with the inner casing walls 803, in order to channel the air flow as desired.
[00127] Figures 10a to 10d shows a ninth embodiment of the smoking system according to the invention. Figure 10a shows a cross-sectional view of the nozzle end of the eighth embodiment of the smoking system 900. In figure 10a, the smoking system 900 includes guides for channeling the air flow within the smoking system. In this embodiment, the guides are provided on the removable insert 901 and on the walls in the form of an enclosure 903. The air flow is shown by dotted arrows.
[00128] Removable insert 901 is similar to removable inserts 601, 701 and 801 and extends only through the center of the smoking system 900, thus directing the air flow between the air inlet and the capillary wick and heating coil to the outside of the envelope circumference. In figure 10a, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 901, although this need not be the case.
[00129] In addition, the inner walls of enclosure 903 provide guides for channeling the flow of the aerosol into the capillary wick and heating coil and outside the capillary wick and heating coil. In this embodiment, the walls of the enclosure 903 are formed so that the inlet of air flow to the capillary wick and heating coil is directed through an upstream channel 905 tangential to the circular cross section of the enclosure and the circular cross section of the aerosol forming chamber 902. In addition, the walls of the enclosure 903 are formed so that the outflow of air from the capillary wick and heating coil is directed through a channel downstream 907 also tangential to the circular cross section of the enclosure and the circular cross section of the aerosol forming the chamber 902. In addition, the walls of the shell 903 are formed to provide a pendulum surface 909 downstream of the capillary wick and heating coil. Surface 909 can allow larger aerosol particles to be trapped. This is shown schematically in figure 10a. The inner walls of the enclosure also define the aerosol forming the chamber 902. The inner walls of the enclosure 903 can be tapered to direct the air flow to the air outlet, although this is not shown in figure 10a.
[00130] Figure 10b is a cross section along the line GG of figure 10a showing upstream channel 905. The walls of enclosure 903 are formed so that channel 905 provides an air flow to the capillary wick and heating coil that is in the tangential direction. This produces a spiral airflow around the capillary wick and heating coil.
[00131] Figure 10c is a cross section along the HH line of figure 10a showing the channel downstream 907. The walls of the enclosure 903 are formed so that the channel 907 provides an air flow away from the capillary wick and coil heating element that is in the tangential direction. That is, after the air is spiraling around the capillary wick and heating coil, it is directed in the tangential direction and then towards the air outlet.
[00132] Figure 10d shows an alternative cross section along the line H-H of figure 10a, also showing downstream channel 907 '. In figure 10c, channel 907 is on the same side of the device as channel 905. In figure 10d, channel 907 'is on the opposite side of the device as channel 905.
[00133] The embodiment shown in figures 10a, 10b, 10c and 10d provides an air flow directed tangentially substantially to the capillary wick and heating coil, a spiral air flow substantially around the capillary wick and heating coil and a air flow directed tangentially substantially out of the capillary wick and heating coil and then to the air outlet. It has been found that managing airflow in this way improves aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The formed inner walls 903 of the housing, together with the insert 901 direct the air flow in order to supply fresh, unsaturated air to the capillary wick and heating coil. This decreases the size of the aerosol particle inhaled by a user. The spiral airflow around the capillary wick and heating coil increases turbulence and reduces aerosol particle size. Larger aerosol particles can also become trapped in the internal walls of the aerosol forming the chamber 902 due to centrifugal forces. This is shown schematically in figure 10a. The tangentially directed outlet airflow means that once the airflow has circulated through the capillary wick and heating coil, it is immediately evacuated to the air outlet. An additional tangent upstream or downstream channel can be provided which can provide better flow distribution within the aerosol forming the chamber. The size of the tangential channels and their relative position to the longitudinal axis of the device influence the air flow around the capillary wick and heating coil and therefore the characteristics of the aerosol.
[00134] A number of variations are possible in the smoking system of figures 10a, 10b, 10c and 10d. The cross section of the device is preferably circular, so that channels 905 and 907 can define a tangential air flow. However, other shapes of the cross section are also possible since the tangential channels can be defined. More than one air inlet (in the enclosure) can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure or as a combination of both (removable insert 901 combined with enclosure-shaped walls 903, as shown) . Similarly, the guides downstream of the capillary wick and heating coil can be formed as one or more removable portions or alternatively as an integral part of the enclosure (enclosure-shaped walls 903, as shown) or as a combination of both. Insert 901 is shown without channels, although longitudinal channels to the outside of insert 901 can be provided. In addition, if channels are provided, the insert can extend across the entire cross section of the housing. Any channel configuration can be provided. The channels can be twisted around the housing axis in order to encourage a swirling air flow. Any channels in insert 901 can be formed by machining. Alternatively, the insert can be formed with channels or holes already formed, through injection molding. Insert 901 may comprise a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned within the system smoke. This is important for electrical connections to the heating coil, for example. The inner walls of the casing 903 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber within the smoking system. This affects the flow of the aerosol in a spiral around the capillary wick and heating coil and therefore the characteristics of the aerosol. The tangential channels 905, 907 can be positioned at any height along the capillary wick and can have any suitable cross section. Any tangential number upstream and downstream channel can be provided.
[00135] Figures 11a to 11d show a tenth modality of the smoking system according to the invention. Figure 11a shows a cross-sectional view of the smoking system including removable insert 1001. Figure 11b is a cross section along line B-B of figure 11a, showing the end of the nozzle only. Figure 11c is a cross section along line C-C of figure 11a, showing the end of the nozzle only. In figures 11a, 11b and 11c, the smoking system 1000 includes guides for channeling the air flow within the smoking system. The air flow is shown by dotted arrows.
[00136] The removable insert 1001 is shown in the cross section in figure 11a. The insert includes channels upstream 1003 for channeling air flow from the air inlet to the capillary wick and heating coil and channel downstream 1005 for channeling the air flow away from the capillary wick and heating coil to the air outlet. Channels 1003 and 1005 are substantially perpendicular to one another and also substantially perpendicular to the longitudinal axis of the enclosure.
[00137] Figure 11b shows a cross section along B-B of figure 11a and Figure 11c shows a cross section along C-C of figure 11a. As seen in figures 11b and 11c, in this embodiment, the guides are provided by removable insert 1001 and removable insert 1007. Removable insert 1007 is similar to removable inserts 601, 701, 801 and 901 and extends only through the center of the system to smoke 1000, thus directing the air flow between the air inlet and the capillary wick and heating coil to the outside of the circumference of the enclosure. In figures 11b and 11c, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 1007, although this need not be the case. The removable insert 1001 is positioned around the capillary wick and heating coil. The removable insert 1001 extends across the entire cross section of the device.
[00138] Because figure 11b shows a cross section along B-B of figure 11a, Figure 11b shows the air flow upstream of the capillary wick and heating coil. As shown in figures 11a and 11b, channels 1003 direct the air flow to the capillary wick and heating coil in a substantially radial direction, that is, substantially perpendicular to the longitudinal axis of the housing.
[00139] Because figure 11c shows a cross section along C-C of figure 11a, Figure 11c shows the air flow downstream of the capillary wick and heating coil. As shown in figures 11a and 11c, channels 1005 direct airflow away from the capillary wick and heating coil in a substantially radial direction. In addition, channels 1005 define the aerosol forming the chamber 1002.
[00140] The walls of the enclosure may additionally be conical at the air outlet, although this is not shown in figures 11b and 11c.
[00141] Figure 11d shows an alternative arrangement for the removable insert 1001 '. In this embodiment, the insert includes four channels upstream 1003 'to channel the air flow from the air inlet to the capillary wick and heating coil. As in figure 11a, the insert also includes two channels downstream 1005 'to channel the air flow away from the capillary wick and heating coil to the air outlet. Channels 1003 'and 1005' are substantially perpendicular to the longitudinal axis of the enclosure. The channels are directed in the radial direction. Although two upstream channels 1003 are shown in figure 11a and four upstream channels 1003 'are shown in figure 11d, any suitable number of upstream channels can be provided, all in the radial direction and substantially perpendicular to the longitudinal axis of the enclosure . Similarly, although two downstream channels 1005, 1005 'are shown in figures 11a and 11d, any suitable number of downstream channels can be provided, all in the radial direction and substantially perpendicular to the longitudinal axis of the enclosure.
[00142] The modalities shown in figures 11a to 11d provide an air flow directed radially substantially to the capillary wick and heating coil and an air flow directed radially substantially out of the capillary wick and heating coil. Airflow management in this way has been found to improve aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The guides provided by the inserts 1007 and 1001 channel the air flow as to direct the air flow to the capillary wick and heating coil in a substantially radial direction. This provides the capillary wick and heating coil with fresh, unsaturated air, which decreases the size of the aerosol particle inhaled by a user. The guides provided by the insert 1001 channel the air flow as to direct the air flow out of the capillary wick and heating coil in a substantially radial direction and also to reduce the volume of the aerosol forming the chamber 1002 in the smoking system. This improves the flow from the aerosol to the air outlet. This improves the smoking experience.
[00143] A number of variations are possible in the smoking system from figures 11a to 11d. First, although the cross section of the device is shown to be circular in figures 11a to 11d, this need not be the case. Second, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (inserts 1001 and 1007, as shown) or alternatively as an integral part of the housing or as a combination of both. Similarly, the guides downstream of the capillary wick and heating cap can be formed as one or more removable portions (insertion 1001, as shown) or alternatively as an integral part of the housing or as a combination of both. Insert 1007 is shown without channels, although longitudinal channels to the outside of the insert can be provided. In addition, if channels are provided, the insert can extend across the entire cross section of the housing. Any channel configuration can be provided. The channels can be twisted around the housing axis in order to encourage a swirling air flow. The channels in insert 1007 can be formed by machining. Alternatively, the insert can be formed with channels or holes already formed, through injection molding. Preferably, insert 1007 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned within the housing. smoking system. This is important for electrical connections to the heating coil, for example.
[00144] Any suitable configuration of channels can be provided at insertion 1001. The channels can be uniformly or non-uniformly distributed circumferentially around the insertion. The channels can have a constant cross-sectional shape and area along their length, or the cross-sectional shape can vary along the length. Channels can include some channels having different cross-sectional shapes and areas from others. The channels in insert 1001 can be formed by machining. Alternatively, the insert can be formed with channels or holes already formed, through injection molding. Preferably, insert 1001 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned within the housing. smoking system. This is important for electrical connections to the heating coil, for example. Channels 1005 can be formed appropriately for the desired volume and shape of the aerosol forming the chamber within the smoking system.
[00145] Figures 12a to 12n shows an eleventh embodiment of the smoking system according to the invention. In each of figures 12a to 12n, the smoking system includes guides for channeling the air flow within the smoking system. The air flow is shown by dotted arrows.
[00146] Figure 12a shows a first arrangement of the smoking system 1100, and figure 12b is a cross section along line J-J of figure 12a. In figures 12a and 12b, the guides are provided by the removable insert 1101, the second removable insert 1103 and the inner casing walls 1105. The removable insert 1101 extends only through the center of the smoking system 1100, thus directing the flow of air between the air inlet and the capillary wick and heating coil to the outside of the envelope circumference. In figure 12a, the liquid cartridge, the capillary wick and the heating coil all form parts of the removable insert 1101, although this need not be the case.
[00147] The second removable insert 1103 is formed so that the air flow is directed through the capillary wick and heating coil in a substantially perpendicular direction. That is, the air flow is substantially perpendicular to the longitudinal axis of the envelope and to the capillary wick. The second removable insert 1103 provides an upstream channel 1107 on one side of the insert and a downstream channel 1109 on the other side of the insert. When the insert is positioned around the capillary wick and heating coil, the air flow for this reason directs through the capillary wick and heating coil. The insert 1103 also defines the aerosol forming the chamber 1102.
[00148] In addition, the inner walls of the 1005 housing provide guides for channeling the air and aerosol flow between the capillary wick and heating coil and the air outlet. In this embodiment, the inner wall casings 1105 are tapered towards the air outlet in order to direct the air and flow from the aerosol to the air outlet.
[00149] Figure 12c shows a second arrangement of the smoking system 1100 'and Figure 12d is a cross section along the line K-K of figure 12c. The arrangement shown in figures 12c and 12d is identical to that shown in figures 12a and 12b except that the second removable insert 1103 includes a disturbing 1111 surrounding the capillary wick and heating coil. In this embodiment, the disruptive 1111 comprises a cylindrical tube surrounding the capillary wick and heating coil, with holes to direct the air flow and away from the capillary wick and heating coil. This provides additional turbulence in the aerosol forming the chamber 1102.
[00150] Figure 12e shows another type of removable insertion 1103 '. The modality shown in figure 12e is identical to that shown in figure 11b except that the aerosol forming the chamber is formed with restrictions 1117 for the downstream side. Restrictions 1117 provide turbulence and, in particular, allow airflow to reach the downstream side of the capillary wick and heating coil.
[00151] Figure 12f shows another removable insertion mode 1103 ’’. The embodiment shown in figure 12f provides two upstream channels 1107a and 1107b on opposite sides of the insert and two downstream channels 1109a and 1109b on opposite sides of the insert. Airflow is directed from upstream channel 1107a, directly through the capillary wick and heating coil, to downstream channel 1109b. At the same time, air flow is directed in the opposite direction from upstream channel 1107b, directly through the capillary wick and heating coil, to downstream channel 1109a. This provides additional turbulence. In figure 12f, the aerosol forming the chamber is formed with divisions 1119. This prevents or reduces the flow from upstream channel 1107a to downstream channel 1109a and from upstream channel 1107b to downstream channel 1109b. In figure 12f, the aerosol forming the chamber is formed with restrictions 1117 'for each downstream side, although restrictions 1117' can be omitted. Restrictions 1117 'provide turbulence and, in particular, allow airflow to reach the downstream side of the capillary wick and heating coil.
[00152] Figure 12g shows another layout of the smoking system. In figure 12g, only the liquid cartridge, the capillary wick and the heating coil are shown for clarity. Figure 12h is a cross section, similar to the cross sections in figures 12b, 12d, 12e and 12f, but showing the disposition of figure 12g. In figures 12g and 12h, two pins 1119, 1121 are supplied in the air flow through the capillary wick and heating coil. The pins direct the flow of air and further provides turbulence in the aerosol forming the chamber. In the modality shown in figures 12g and 12h, the pins are the connection pins for the heating coil, pin 1119 being the positive connection, pin 1121 being the negative connection. However, this need not be the case.
[00153] Figure 12i shows an alternative version for the layout shown in figure 12g. In figure 12i, pins 1119 ', 1121' are formed as flags. Pin 1119 'has a portion of pin 1119a at its base and a wide blade portion 1119b at its top. Similarly, pin 1121 'has a portion of pin 1121a at its base and a wide blade portion 1121b at its upper part. This provides better direction of air flow through the capillary wick and heating coil. Figure 12j shows another alternative version for the arrangement shown in figure 12g. In figure 12j, the pins are formed as large heating blades 1119 ’’, 1121 ’’. Again, this provides better direction of airflow through the capillary wick and heating coil.
[00154] Figures 12k and 12l show two alternative arrangements for the pins shown in figures 12i and 12j. Figure 12k is a cross section, similar to the cross sections in figures 12b, 12d, 12e, 12f and 12h. As shown in figure 12k, the blade portions of the pins can be in a straight line towards the downstream direction, that is, towards the downstream channel 1109. Figure 12l is a cross section, similar to the cross sections in figures 12b, 12d , 12e, 12f, 12h and 12k. As shown in figure 12l, the blade portions of the pins can be curved and directed in the downstream direction, that is, towards the downstream channel 1109.
[00155] The modalities shown in figures 12a to 12l provide an air flow directed radially substantially to the capillary wick and heating coil and an air flow directed radially substantially out of the capillary wick and heating coil. In particular, the air flow is directed through the capillary wick and heating coil. Airflow management in this way has been found to improve aerosol formation within the smoking system. Airflow management can also reduce condensation and consequently leakage. The guides provided by inserts 1101 and 1103 of the air flow channel as for directing the air flow to the capillary wick and heating coil in a substantially radial direction. This provides the capillary wick and heating coil with fresh, unsaturated air, which decreases the size of the aerosol particle inhaled by a user. The guides provided by insert 1103 channel the air flow as to direct the air flow out of the capillary wick and heating coil in a substantially radial direction and also to reduce the volume of the aerosol forming the chamber in the smoking system. This improves the flow from the aerosol to the air outlet. In addition, in the air flow, additional components can be provided to increase turbulence. This improves the smoking experience.
[00156] A number of variations are possible in the smoking system from figures 12a to 12l. First, although the cross section of the device is shown as circular in figures 12a to 12l, this need not be the case. Second, more than one air inlet can be provided. The guides upstream of the capillary wick and heating coil can be formed as one or more removable portions (inserts 1101 and 1103, as shown) or alternatively as an integral part of the housing or as a combination of both. Similarly, the guides downstream of the capillary wick and heating cap can be formed as one or more removable portions or alternatively as an integral part of the enclosure or as a combination of both (insert 1103 and enclosure-shaped walls 1105 , as shown). Insert 1101 is shown without channels, although longitudinal channels to the outside of the insert can be provided. In addition, if channels are provided, the insert can extend across the entire cross section of the housing. Any channel configuration can be provided. The channels can be twisted around the housing axis in order to encourage a swirling air flow. The channels in insert 1101 can be formed by machining. Alternatively, the insert can be formed with channels or holes already formed, through injection molding. Preferably, insert 1101 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) within the walls of the enclosure, to ensure that the insert is correctly positioned within the housing. smoking system. This can be important for electrical connections to the heating coil, for example.
[00157] Any suitable channel configuration can be provided in insert 1103 including any suitable number of channels upstream and any suitable number of channels downstream. The channels can have a constant cross-sectional shape and area along their length, or the cross-sectional shape can vary along the length. Channels can include some channels having different cross-sectional shapes and areas from others. The channels in insert 1103 can be formed by machining. Alternatively, the insert can be formed with channels or holes already formed, through injection molding. Preferably, insert 1103 comprises a locating or protruding pin (not shown) on its outer surface to cooperate with a recess (also not shown) on the inside of its enclosure walls, in order to ensure that the insert is correctly positioned inside the smoking system. The insert 1103 can be formed appropriately for the desired volume of the aerosol forming the chamber within the smoking system.
[00158] The pins shown in figures 12g to 12l can have suitable shapes in order to direct the air flow through the capillary wick and the heating element as desired. In addition, even though the pins are shown as the connections for the heating coil, this need not be the case.
[00159] A large number of modalities have been described and it should be understood that the characteristics described in the list for one modality can also be applied to the other modality, where appropriate. The scope of the present invention is defined with reference to the claims that follow.
