    [0001] The present invention relates to an aerosol generating device for heating an aerosol forming substrate. Particularly, but not exclusively, the present invention relates to an electrically operated aerosol generating device for heating a liquid aerosol forming substrate.
    [0002] WO-A-2009/132793 describes an electrically heated smoke formation system. A liquid is stored in a liquid storage portion, and a capillary wick has a first end that extends into the liquid storage portion for contact with the liquid therein, and a second end that extends out of the portion. of liquid storage. A heating element heats the second end of the capillary wick. The heating element is in the form of a spirally wound electrical heating element in electrical connection with a power source, and surrounding the second end of the capillary wick. In use, the heating element can be activated by the user to turn on the power source. Suction on the mouthpiece by the user causes air to be drawn into the electrically heated smoke forming system over the capillary wick and heating element and subsequently into the user's mouth.
    [0003] It is an object of the present invention to improve the aerosol generation in an aerosol generating device or system.
    [0004] According to one aspect of the present invention, there is provided an aerosol generating system comprising an aerosol generating device in cooperation with a cartridge, the system comprising: a vaporizer for heating an aerosol forming substrate; at least one air intake; at least one air outlet, the air inlet and the air outlet being arranged to define an air flow path between the air inlet and the air outlet; and flow control means for adjusting the size of the at least one air inlet so as to control the air flow velocity in the air flow path.
    [0005] The aerosol generating system, comprising the aerosol generating device and the cartridge, is arranged to heat the aerosol forming substrate to form the aerosol. The aerosol generating cartridge or device may include the aerosol forming substrate or may be adapted to receive the aerosol forming substrate. As is known to those skilled in the art, an aerosol is a suspension of solid particles or liquid droplets in a gas, such as air. The aerosol generating system may further comprise an aerosol forming chamber in an air flow path between the at least one air inlet and the at least one air outlet. The aerosol formation chamber can help or facilitate aerosol generation.
    [0006] The flow control means allow a pressure drop at the air inlet to be adjusted. This affects the speed of airflow through the aerosol generating device and cartridge. Airflow velocity affects the average droplet size and droplet size distribution in the aerosol, which can in turn affect the user experience. Thus, flow control means are advantageous for a number of reasons. First, the flow control means allow the drag resistance (which is the pressure drop at the air inlet) to be adjusted, for example, according to the user's preference. Second, for a given aerosol forming substrate, the flow control means allows an average size range of aerosol droplets to be produced. The flow control means may be user operable to create an aerosol having droplet size characteristics that suit the user's preferences. Third, the flow control means allows a particular desired average aerosol droplet size to be produced for the selection of aerosol forming substrates. Thus, the flow control means allows the aerosol generating device and cartridge to be compatible with a variety of different aerosol forming substrates.
    [0007] Furthermore, the air flow velocity can also affect how much condensation forms within the aerosol generating device and cartridge, particularly within the aerosol forming chamber. Condensation can adversely affect liquid leakage from the aerosol generating device and cartridge. Thus, a further advantage of the flow control means is that they can be used to reduce liquid leakage. The distribution and average droplet size in the aerosol can also affect the appearance of any smoke. Thus, fourth, the flow control means can be used to adjust the appearance of any smoke from the aerosol generating device and cartridge, for example, according to user preference or according to the particular environment in which the aerosol generation system is being used.
    [0008] Preferably, the flow control means is user-operable. Thus, the user can select the size of at least one air inlet. This results in affecting the average droplet size and droplet size distribution. The desired aerosol can be selected by the user for a particular aerosol forming substrate or for selecting aerosol forming substrates usable with the aerosol generating device and cartridge. Alternatively, the flow control means may be operable by a manufacturer to select a desired size for the at least one air inlet.
    [0009] In a preferred embodiment, the flow control means comprises: a first member and a second member, the first and second members cooperating to define the at least one air inlet, wherein the first and second members are arranged to move with respect to each other so as to vary the size of the at least one air inlet.
    [00010] Preferably, the two members are sheet-shaped. Leaf-shaped members can be flat or curved. Preferably, the two flat members move with respect to each other by sliding over each other. Alternatively, the two flat members can move relative to each other along a thread, for example a screw thread.
    [00011] Preferably, the aerosol generating device comprises one of the first member and the second member, and the cartridge comprises the other of the first member and the second member. The aerosol generating device and the cartridge may each comprise a housing. Preferably, the first member and the second member form a part of the housing of each of the device and cartridge. The cartridge may comprise the nozzle piece. The housing can comprise any suitable material or a combination of materials. Examples of suitable materials include metals, alloys, plastics or composite materials containing one or more of said materials, or thermoplastics which are suitable for application in the food or pharmaceutical industry, for example polypropylene, polyetheretherketone (PEEK) and polyethylene. Preferably, the material is lightweight and not brittle.
    [00012] The first member can include an opening. The second member can include an opening. Preferably, the first member comprises at least a first opening and the second member comprises at least a second opening; the first and second openings together forming the at least one air inlet; and wherein the first and second members are arranged to move with respect to one another so as to vary the overlapping extent of the first opening and the second opening so as to vary the size of the at least one air inlet.
    [00013] If there is very little overlap between the first opening and the second opening, the resulting air intake will be provided with a small cross-sectional area. If there is a large amount of overlap between the first opening and the second opening, the resulting air intake will have a large cross-sectional area. The first opening can be provided with any suitable shape. The second opening can be provided with any suitable shape. The shapes of the first opening and the second opening can be the same or different. Any number of openings can be provided on the first member and on the second member. The number of openings in the first member may be different from the number of openings in the second member. Alternatively, the number of openings in the first member may be the same as the number of openings in the second member. In that case, each opening in the first member may align with the respective opening in the second member to form an air inlet. Thus, the number of air inlet portions can be the same as the number of openings in each of the first and second members. Additional air inlet portions may be provided having a fixed cross-sectional area, which are not adjustable by the flow control means.
    [00014] In one embodiment, the first member and the second member are rotationally movable relative to each other. In one embodiment, the first member and the second member are linearly movable relative to each other. In one embodiment, the first member and the second member pivot relative to each other so as to vary the size of the at least one air inlet; no linear motion is involved. In another embodiment, the first member and the second member move linearly relative to each other so as to vary the size of the at least one air inlet; there is no rotation. However, in another embodiment, the first member and the second member rotate and move linearly relative to each other, for example, by a screw thread. For example, if the first and second members form a part of the housing of the aerosol generating device and cartridge, the first and second members may be connectable by a screw thread to assemble the aerosol generating system. The screw thread may also allow the first and second members to move relative to one another, thereby providing the flow control means.
    [00015] Preferably, the cartridge includes the first member and the aerosol generating device includes the second member. In a preferred embodiment, the cartridge comprises a housing having a first sleeve comprising the first member and including at least a first opening, and the aerosol generating device comprises a housing having a second sleeve comprising the second member and including at least one second opening. , wherein the at least one first opening and the at least one second opening together form the at least one air inlet, and wherein the first sleeve and the second sleeve are rotatable with respect to one another so as to vary the extent of overlapping of the first opening and the second opening so as to vary the cross-sectional area of the air inlet. One of the first sleeve and the second sleeve can be an outer sleeve, and the other one of the first sleeve and the second sleeve can be an inner sleeve.
    [00016] The flow control means is for adjusting the size of the at least one air inlet. They allow the airflow velocity in the airflow path to be varied. Additionally, the at least one air outlet can be adjustable in size. This can allow drag resistance to be varied, for example, according to user preference.
    [00017] The at least one air inlet can form part of the cartridge or part of the aerosol generating device. If there is more than one air inlet, one or more of the air inlet portions may form part of the cartridge and one or more other of the air inlet portions may form part of the aerosol generating device. The flow control means can form part of the cartridge or the device. Alternatively, the flow control means can be formed by cooperation between the cartridge part and the device part. If the flow control means comprise a first member and a second member, not only the first but also the second member can be contained in the cartridge, or not only the first but also the second member can be contained in the device, or one of the the first and second members can be contained in the cartridge and the other of the first and second members can be contained in the device.
    [00018] If the first and second members comprise the outer and inner sleeves, the outer sleeve and the inner sleeve may form part of the device, or the outer sleeve and the inner sleeve may form part of the cartridge, or one of the outer sleeve and the inner sleeve may form part of the device and the other of the outer sleeve and the inner sleeve may form part of the cartridge.
    [00019] The aerosol forming substrate is capable of releasing volatile compounds that can form an aerosol. Volatile compounds can be released by heating the aerosol forming the substrate, or they can be released by a chemical reaction or mechanical stimulus. The aerosol forming substrate can contain nicotine. The aerosol forming substrate can be a solid aerosol forming substrate. The aerosol forming substrate preferably comprises a tobacco containing material containing volatile tobacco flavor compounds which are released from the substrate upon heating. The aerosol forming substrate may comprise a material other than tobacco. The aerosol forming substrate may comprise tobacco-containing material and non-tobacco-containing material. Preferably, the aerosol forming substrate further comprises an aerosol former. Examples of suitable aerosol formers are glycerin and propylene glycol.
    [00020] However, in a preferred embodiment, the aerosol forming substrate is a liquid aerosol forming substrate. The liquid aerosol forming substrate preferably has physical properties, for example boiling point and vapor pressure, suitable for use in the aerosol generating device and cartridge. If the boiling point is too high, it may not be possible to heat the liquid, but if the boiling point is too low, the liquid can heat up too quickly. The liquid preferably comprises a material containing volatile tobacco aroma tobacco-comprising compounds which are released from the liquid upon heating. Alternatively, or in addition, the liquid may comprise a material other than tobacco. The liquid can include aqueous solutions, non-aqueous solvents such as ethanol, plant extracts, nicotine, natural or artificial flavors or any combination of the foregoing. Preferably, the liquid additionally comprises an aerosol former which facilitates the formation of a dense, stable aerosol. Examples of suitable aerosol formers are glycerin and propylene glycol.
    [00021] If the aerosol forming substrate is a liquid substrate, the aerosol generating system may further comprise a storage portion for storing the liquid aerosol forming substrate. Preferably, the liquid storage portion is provided in the cartridge. An advantage of providing the storage portion is that the liquid in the liquid storage portion is protected from ambient air (by the fact that air cannot generally enter the liquid storage portion) and in some light modalities , so the risk of liquid degradation is significantly reduced. Furthermore, a high level of hygiene can be maintained. The liquid storage portion may not be able to be refilled. Thus, when the liquid in the liquid storage portion has used up, the aerosol generating system or cartridge is replaced. Alternatively, the liquid storage portion can be refilled. In that case, the aerosol generating system or cartridge can be replaced after a certain number of refills of the liquid storage portion. Preferably, the liquid storage portion is arranged to contain liquid for a predetermined number of puffs.
    [00022] The aerosol forming substrate may alternatively be any other type of substrate, for example a gas substrate, a gel substrate or any combination of the various substrate types.
    [00023] If the aerosol forming substrate is a liquid aerosol forming substrate, the aerosol generating system vaporizer may comprise a capillary wick to transport the liquid aerosol forming substrate by capillary action. The capillary wick may be provided in the aerosol generating device or in the cartridge, but preferably, the capillary wick is provided in the cartridge. Preferably, the capillary wick is arranged to be in contact with the liquid in the liquid storage portion. Preferably, the capillary wick extends into the liquid storage portion. In that case, in use, liquid is transferred from the liquid storage portion by capillary action in the capillary wick. In one embodiment, the liquid at one end of the capillary wick is vaporized by the heater to form a supersaturated vapor. Supersaturated vapor is mixed with and carried into the air stream. During flow, the vapor condenses to form the aerosol and the aerosol is carried toward a user's mouth. The aerosol forming liquid substrate has suitable physical properties, including surface tension and viscosity, which allow the liquid to be transported through the capillary wick by capillary action.
    [00024] The hair strand can be endowed with a fibrous or spongy structure. The capillary wick preferably comprises a bundle of capillaries. For example, the capillary wick may comprise a plurality of fibers or strands or other fine-hole tubes. Fibers or yarns can generally be aligned in the longitudinal direction of the aerosol generating system. Alternatively, the capillary wick may comprise a sponge-shaped or foam-shaped material formed into a rod shape. The rod shape can extend along the longitudinal direction of the aerosol generating system. The wick structure forms a plurality of small holes or tubes through which liquid can be transported by capillary action. The capillary wick can comprise any suitable material or combination of materials. Examples of suitable materials are capillary materials, for example a sponge material or foam material, ceramic- or graphite-based materials in the form of fibers or sintered powders, plastic materials or foamed metal, a fibrous material, for example, produced from spun or extruded fibers, such as cellulose acetate, polyester, or bonded polyolefin fibers, polyethylene, terylene or polypropylene, nylon or ceramic fibers. The capillary wick can be provided with adequate capillarity and porosity in order to be used with liquids of different physical properties. The liquid has physical properties, including, but not limited to, viscosity, surface tension, density, thermal conductivity, boiling point and vapor pressure, which allow the liquid to be transported through the capillary device by capillary action. The capillary wick must be suitable so that the required amount of liquid can be sent to the vaporizer.

The heater can heat the aerosol-forming substrate via conduction and can be at least partially in contact with the substrate, or a vehicle on which the substrate is deposited. Alternatively, heat from the heater can be conducted to the substrate via an intermediate heat-conducting element. Alternatively, the heater can transfer heat to incoming ambient air which is drawn through the aerosol generating system during use, which in turn heats the aerosol forming substrate by convection. In a preferred embodiment, the aerosol generating system is electrically operated and the vaporizer of the aerosol generating system comprises an electrical heater for heating the aerosol forming substrate.

The heating element or heating elements can be suitably arranged to most efficiently heat the aerosol forming substrate.
    [00029] The at least one electrical heating element preferably comprises an electrically resistive material. Suitable electrically resistive materials include, but are not limited to: semiconductors such as additive ceramics, electrically "conductive" ceramics (such as, for example, molybdenum disilicilide), carbon, graphite, metals, metal alloys, and composite materials produced from a ceramic material and a metallic material. Said composite materials may comprise additive ceramics or non-additive ceramics. Examples of suitable add-on ceramics include add-on silicon carbides.

Examples of suitable metal alloys include stainless steel, Constantan, alloys containing nickel-, cobalt-, chromium-, aluminum-titanium-zirconium-, hafnium-, niobium-, molybdenum-, tantalum-, tungsten-, tin-, gallium- , manganese- and iron-, and nickel-based superalloys, iron, cobalt, stainless steel, Timetal®, ferroaluminum-based alloys and iron-manganese-aluminum-based alloys. Timetal® is a registered chest of Titanium Metals Corporation, 1999 Broadway Suite 4300, Denver Colorado. In composite materials, the electrically resistive material can optionally be encapsulated or coated with an insulating material or vice versa, depending on the energy transfer kinetics and external physicochemical properties required. The heating element may comprise an engraved metal foil insulated between two layers of an inert material. In that case, the inert material may comprise Kapton®, an all-polyimide or mica sheet.

Alternatively, the at least one electrical heating element may take the form of an enclosure or substrate having different electro-conductive portions, or an electrically resistive metal tube. The liquid storage portion may incorporate a disposable heating element. Alternatively, if the aerosol-forming substrate is liquid, one or more needles or heating rods which travel through the liquid aerosol-forming substrate may also be suitable. Alternatively, the at least one electrical heating element may be a disc (end) heater or a combination of a disc heater with heating needles or rods. Alternatively, the at least one electrical heating element may comprise a flexible sheet of material. Other alternatives include a heating wire or filament, for example nickel-chromium (Ni-Cr), platinum, tungsten or alloy wire, or a heating plate. Optionally, the heating element can be deposited on or in a rigid vehicle material.

Suitable heat sensitive storage materials include silica gel, alumina, carbon, glass mat, fiberglass, minerals, a metal or an alloy such as aluminum, silver or lead, and a cellulose material. Other suitable materials that release heat through a reversible phase change include paraffin, sodium acetate, naphthalene, wax, polyethylene oxide, a metal, metal salt, a mixture of eutectic salts, or an alloy.
    [00033] The heat sink can be arranged so that it is directly in contact with the aerosol forming substrate and can transfer the stored heat directly to the substrate. Alternatively, heat stored in the heat sink or heat reservoir can be transferred to the aerosol-forming substrate by means of a heat conductor, such as a metal tube.

Ambient air can be heated before passing through the aerosol forming substrate. Alternatively, ambient air can first be drawn through the liquid substrate and then heated.
    [00036] The electric heater can be contained in the device or in the cartridge. Preferably, but not necessarily, the electric heater is contained in the same portion as the capillary wick.
    [00037] In a preferred embodiment, the aerosol forming substrate is a liquid aerosol forming substrate, the aerosol generating system comprises the storage portion for storing the liquid aerosol forming substrate, and the vaporizer of the aerosol system.

In one embodiment, the capillary wick has a first end and a second end, the first end extending into the liquid storage portion for contact with liquid therein and the electric heater being arranged to heat liquid at the second end. In another embodiment, the capillary wick may lie along the edge of the liquid storage portion. When the heater is activated, the liquid at the second end of the capillary wick is vaporized by the heater to form supersaturated vapor. Supersaturated vapor is mixed with and carried into the air stream. During flow, the vapor condenses to form the aerosol and the aerosol is carried toward a user's mouth.
    [00038] However, the present invention is not limited to heating vaporizers but can be used in aerosol generating systems in which the resulting vapor and aerosol is generated by a mechanical vaporizer, for example, but not limited to a piezo vaporizer or a atomizer using pressurized liquid.

When the heater is activated, the liquid at the second end of the capillary wick is vaporized by the heater to form supersaturated vapor.
    [00056] According to another aspect of the present invention, there is provided a method for varying the air flow velocity in an aerosol generating system comprising an aerosol generating device in cooperation with a cartridge, the aerosol generating system comprising a vaporizer for heating an aerosol forming substrate to form an aerosol, at least one air inlet, and at least one air outlet, the air inlet and air outlet being arranged to define an air flow path between the air inlet and the air outlet, the method comprising: adjusting the size of the at least one air inlet so as to vary the airflow velocity in the airflow path.
    [00057] Adjusting the size of the at least one air inlet varies the pressure drop across the air inlet. This affects the speed of airflow through the aerosol generating system and drag resistance. Airflow velocity affects the average droplet size and droplet size distribution in the aerosol, which can in turn affect the user experience.
    [00058] In one embodiment, the aerosol generating system comprises a first member and a second member, the first and second members cooperating to define the at least one air inlet, and wherein the step of adjusting the size of the at least an air inlet comprises moving the first and second members with respect to one another so as to vary the size of the at least one air inlet. One of the first and second members may be provided in the aerosol generating device, and the other of the first and second members may be provided in the cartridge.
    [00059] Additional features described in relation to one aspect of the present invention may be applicable to another aspect of the present invention. In particular, the additional features described in relation to the aerosol generating device may also be applicable to the cartridge.
    [00060] The present invention will be further described, by way of example only, with reference to the attached drawings, of which:
    [00061] Figure 1 shows an embodiment of an aerosol generating system according to the present invention; Figure 2 is a perspective view of portion of an aerosol generating system in accordance with the present invention, showing the air inlet portions in more detail; Figure 3 is a graph showing drag resistance as a function of the cross-section of the airflow path in an aerosol generating system; Figure 4 is a graph showing the effect of airflow coefficient on aerosol droplet size for a given aerosol forming substrate in an aerosol generating system; and Figure 5 is a graph showing the effect of airflow coefficient on aerosol droplet size for two alternative aerosol forming substrates in an aerosol generating system.
    [00062] Figure 1 shows an example of an aerosol generating system according to the present invention. In Figure 1, the system is an electrically operated smoking system having a storage portion. The smoking system 101 of Figure 1 comprises a cartridge 103 and a device 105. In the device 105, an electrical power source in the form of battery 107 and electrical circuit in the form of hardware 109 and puff detection system 111 is provided. cartridge 103, there is provided storage portion 113 containing liquid 115, a capillary wick 117 and a vaporizer in the form of heater 119. Note that the heater is only shown schematically in Figure 1. In the exemplary embodiment shown in Figure 1, a one end of the capillary wick 117 extends into the liquid storage portion 113 and the other end of the capillary wick 117 is surrounded by the heater 119. The heater is connected to the electrical circuit via connections 121, which can pass along the outside. of the liquid storage portion 113 (not shown in Figure 1). Cartridge 103 and device 105 each of which includes apertures which, when cartridge and device are assembled together, align to form air inlet portions 123. Flow control means (to be further described with reference to Figures 2 to 5) are provided, allowing the size of the air inlet portions 123 to be adjusted. Cartridge 103 additionally includes an air outlet 125, and an aerosol forming chamber 127. The air flow path from the air inlet portions 123 through the aerosol forming chamber 127 to the air outlet 125 is shown by the dotted arrows.
    [00063] In use, operation is as follows. Liquid 115 is transported by capillary action from the liquid storage portion 113 from the end of the wick 117 which extends into the liquid storage portion to the other end of the wick which is surrounded by the heater 119. When a user pulls on the aerosol generating system at the air outlet 125, ambient air is drawn through the air inlet portions 123 as shown by the dotted arrows. In the arrangement shown in Figure 1, the puff detection system 111 reads the puff and activates the heater 119. The battery 107 supplies electrical energy to the heater 119 to heat the end of the wick 117 surrounded by the heater. The liquid at that end of wick 117 is vaporized by heater 119 to create a supersaturated vapor. At the same time, the liquid being vaporized is replaced by additional liquid that moves along the wick 117 by capillary action. This is sometimes referred to as "pumping action". The supersaturated vapor created is mixed with and carried into the air stream from the air inlet portions 123. In the aerosol formation chamber 127, the vapor condenses to form an inhalable aerosol, which is carried towards the outlet 125 and into the user's mouth.
    [00064] In the modality shown in Figure 1, the hardware 109 and the puff detection system 111 are preferably programmable. Hardware 109 and puff detection system 111 can be used to manage the operation of the aerosol generation system.
    [00065] Figure 1 shows an example of an aerosol generating system according to the present invention. Many other examples are possible, however. The aerosol generating system simply needs to comprise an aerosol generating device and a cartridge and include a vaporizer for heating the aerosol forming substrate to form an aerosol, at least one air inlet, at least one air outlet, and flow control means (to be described below with reference to Figures 2 to 5) for adjusting the size of the at least one air inlet so as to control the air flow velocity in the air flow path from the air inlet. air to the air outlet. For example, the system does not need to be electrically operated. For example, the system does not need to be a smoking system. For example, the aerosol forming substrate need not be a liquid aerosol forming substrate. Furthermore, even if the aerosol forming substrate is a liquid aerosol forming substrate, the system may not include the hair swab. In that case, the system may include another mechanism for sending liquid for vaporization. Additionally, the system may not include a heater, in which case another device may be included to heat the aerosol forming substrate. For example, a puff detection system does not need to be provided. Instead, the system can operate by manual activation, for example, the user operating a key when a puff is performed. For example, the general shape and size of the aerosol generating system can be changed.
    [00066] As discussed above, in accordance with the present invention, the aerosol generating system includes flow control means to adjust the size of the at least one air inlet, so as to control the velocity of air flow in the pathway. of air flow through the aerosol generation system. An embodiment of the present invention, including the flow control means, will now be described with reference to Figures 2 to 5. The embodiment is based on the example shown in Figure 1, although it is applicable to other embodiments of the aerosol generating systems. Note that Figures 1 and 2 are schematic in nature. In particular, the components shown are not necessarily to scale either individually or in relation to one another.
    [00067] Figure 2 is a perspective view of the portion of the aerosol generating system of Figure 1, showing in more detail the air inlet portions 123. Figure 2 shows the cartridge 103 of the aerosol generating system 101 assembled with the device 105 of the aerosol generating system 101. The cartridge 103 and the device 105 each include openings which, when the cartridge and device are assembled together, align or partially align to form the inlet portions. air 123.
    [00068] In use, the cartridge 103 and the device 105 can be rotated with respect to each other as shown by the arrow. The overlapping extent of the sets of openings in the cartridge 103 and the device 105 define the size of the air inlet portions 123. The size of the air inlet portions 123 influences the velocity of air flow through the aerosol generating system 101, which in turn affects the aerosol droplet size. This will be further described with reference to Figures 3 to 5.
    [00069] Figure 3 is a graph showing drag resistance (pressure drop in Pascals (Pa)) as a function of the cross-section of the airflow path (mm2) in an aerosol generating system. As can be seen in Figure 3, the pressure drop increases as the cross section of the airflow path decreases. (Note that the relationship shown in Figure 3 is for a given flow coefficient, which is a combination of puff duration and puff volume). The relationship between the pressure drop dP and the cross-sectional area of the airflow path S2 follows an inverse parabolic relationship of the form dP = a/S2, where a is a constant. Thus, rotating the device 105 and the cartridge 103 with respect to each other to increase the size of the air inlet portions 123 in the aerosol generating system increases the cross-sectional area of the air flow path, which reduces drop. pressure or drag resistance. Rotating device 105 and cartridge 103 with respect to each other to decrease the size of the air inlet portions 123 in the aerosol generating system decreases the cross-sectional area of the air flow path, which increases the pressure drop or drag resistance.
    [00070] As already mentioned, the size of the air inlet portions 123 influences the velocity of air flow through the aerosol generating system 101. This, in turn, affects the droplet size in the aerosol as will now be described. It is known in the art that increasing the cooling coefficient in an aerosol generating system decreases the average droplet size in the resulting aerosol. The cooling coefficient is a combination of the temperature gradient between the vaporizer and the surrounding temperature and the velocity of local airflow to the vaporizer. The temperature gradient is determined and fixed by ambient conditions, so the cooling coefficient is mainly driven by the velocity of the local air flow through the aerosol generation system, in particular through the aerosol formation chamber at the location of the vaporizer . Thus, adjusting the air flow velocity through the aerosol forming chamber of the aerosol generating system allows for the generation of different types of aerosols for a given aerosol forming substrate.
    [00071] Figure 4 is a graph showing the effect of airflow coefficient (liters per minute) on aerosol droplet size (microns) for a given aerosol forming substrate in an aerosol generating system. It can be seen from Figure 4 that increasing the airflow coefficient through the aerosol generating system decreases the average aerosol droplet size. Conversely, decreasing the coefficient of airflow through the aerosol generating system increases the average droplet size in the resulting aerosol.
    [00072] Two points on the curve of Figure 4, A and B, have been marked. State A has a relatively low airflow coefficient through the aerosol generating system, resulting in a relatively large average droplet size in the resulting aerosol. This corresponds to a relatively large airflow path cross-sectional area, which results in a relatively low drag resistance, and thus a relatively low airflow coefficient. Thus, state A corresponds to the device 105 and the cartridge 103 of the aerosol generating system (see Figures 1 and 2) being rotated with respect to each other so as to result in a relatively large overlap between the openings in the device 105 and the cartridge 103. This results in a relatively large air inlet 123, for example 100% of the maximum air inlet size. In contrast, state B has a relatively high coefficient of airflow through the aerosol generating system, resulting in a relatively small average droplet size in the resulting aerosol. This corresponds to a relatively small cross-sectional area of the airflow path, which results in a relatively high drag resistance and thus a relatively high airflow coefficient. Thus, state B corresponds to the device 105 and the cartridge 103 of the aerosol generating system being rotated with respect to each other so as to result in a relatively small amount of overlap between the openings in the device 105 and the cartridge 103. This results. in a relatively small air inlet 123, for example, 40% of the maximum air inlet size.
    [00073] As shown in Figure 4, the present invention allows the size of the at least one air inlet to be adjusted so as to control the air flow velocity in the air flow path. This allows the generation of different types of aerosols (ie aerosols with different average droplet sizes and droplet size distribution) for a given aerosol forming substrate.
    [00074] Alternatively, adjusting the velocity of the air flow through the aerosol forming chamber of the aerosol generating system allows a desired aerosol droplet size to be produced for a variety of aerosol forming substrates. Figure 5 is a graph showing the effect of airflow coefficient (liters per minute) on aerosol droplet size (microns) for two alternative aerosol forming substrates 501, 503 in an aerosol generating system. As in Figure 4, for both aerosol forming substrates 501 and 503, increasing the airflow coefficient through the aerosol generating system decreases the average aerosol droplet size and decreases the airflow coefficient through the system of aerosol generation increases the average aerosol droplet size. For a given airflow coefficient, aerosol forming substrate 501 results in a smaller average aerosol droplet size than aerosol forming substrate 503.
    [00075] Two points A and B have been marked in Figure 5. A is on the curve for aerosol forming substrate 501. B is on the curve for aerosol forming substrate 503. In A and B the mean droplet size of resulting aerosol is the same. For state A, because of the properties of aerosol forming substrate 501, the air flow coefficient that results in that average aerosol droplet size is relatively low. This corresponds to a relatively large cross-sectional area of the airflow path, which results in a relatively low drag resistance, and thus a relatively low airflow coefficient. Thus, state A corresponds to the device 105 and the cartridge 103 of the aerosol generating system (see Figures 1 and 2) being rotated with respect to each other so as to result in a relatively large overlap between the openings in the device 105 and the cartridge 103. This results in a relatively large air inlet 123, for example 100% of the maximum air inlet size. For state B, however, because of the properties of aerosol forming substrate 503, the airflow coefficient that results in that average aerosol droplet size is relatively high. This corresponds to a relatively small cross-sectional area of the airflow path, which results in a relatively high drag resistance, and thus a relatively high airflow coefficient. Thus, state B corresponds to the device 105 and the cartridge 103 of the aerosol generating system being rotated with respect to each other so as to result in a relatively small overlap between the openings in the device 105 and the cartridge 103. This results in a relatively small air inlet 123, for example, 40% of the maximum air inlet size.
    [00076] As shown in Figure 5, the present invention allows the size of the at least one air inlet to be adjusted so as to control the air flow velocity in the air flow path. This allows the generation of a desired aerosol (which is having the desired average droplet size and droplet size distribution) for a variety of aerosol forming substrates.
    [00077] In the described mode, the rotation of the device 105 and the cartridge 103 with respect to each other provides a flow control means that allow the pressure drop in the air inlet portions 123 to be adjusted. This affects the speed of airflow through the aerosol generating system. Airflow velocity affects the average droplet size and droplet size distribution in the aerosol, which can in turn affect the user experience. Thus, the flow control means allow the drag resistance (which is pressure drop at the air inlet) to be adjusted, for example, according to the user's preference. Additionally, for a given aerosol forming substrate, the flow control means allows an average size range of aerosol droplets to be produced, and the desired aerosol can be selected by a user according to the user's preference. Also, the flow control means allows a particular desired average aerosol droplet size to be produced for the selection of aerosol forming substrates. Thus, the flow control means allows the aerosol generating system to be compatible with a variety of different aerosol forming substrates and the flow control means allows the user to select the desired properties of the aerosol for a number of different compatible aerosol forming substrates.
    [00078] In Figure 2, the flow control means are provided by rotating the device 105 and the cartridge 103 of the aerosol generating system relative to each other. However, the means of flow control need not be provided by the cooperation of the two portions of the system. Flow control means can be provided in device 105. Alternatively or additionally, flow control means can be provided in cartridge 103. In fact, the aerosol generating system need not comprise a separate cartridge and device. Additionally, in the embodiment of Figure 2, the size of the air inlet portions 123 is adjusted by varying the overlapping extent of the openings in the device 105 and the cartridge 103. However, the flow control means need not be formed by overlapping. two sets of openings. The flow control means can be provided by any other suitable mechanism. For example, the flow control means may be provided by a single opening having a movable shutter to open and close the opening. Additionally, in the embodiment of Figure 2, device 105 and cartridge 103 are swivel relative to one another. However, alternatively, device 105 and cartridge 103 may be movable linearly relative to each other, for example, by sliding. Alternatively, device 105 and cartridge 103 may be movable relative to one another by a combination of rotational and linear movement, for example by a screw thread. Additionally, any suitable number, arrangement and shapes of openings can be provided.
    [00079] Thus, according to the present invention, the aerosol generating system includes flow control means for adjusting the size of at least one air inlet so as to control the air flow velocity in the air flow path. air through the aerosol generation system. Aerosol generation system modalities and flow control means have been described with reference to Figures 2 to 5.
