专利说明:

[001] The present invention relates to electrical systems in which a secondary device, which has a source of rechargeable electrical energy, is recharged by a primary device. In particular, the description refers to a system comprising a portable aerosol generating device that can be connected to a main power supply device.
[002] An example of such an electrical system having a portable device and a main charging device is an electrically operated smoking system. Electrically operated smoking systems significantly reduce secondary smoking when compared to lit-end smoking devices, while allowing the consumer to selectively activate the smoking system during the smoking experience. Electrically operated smoking systems typically include an aerosol generating device, having a housing for receiving an aerosol generating article or a smoking article, heating elements for generating an aerosol, a power source and a necessary electronic circuit. The circuit may, for example, be a circuit for controlling the heating and charging of the aerosol generating device. Having a portable device and primary charge device provides the advantage of a small aerosol generating device being the portable device that is easy to hold and use, but also the ability to quickly and conveniently recharge the aerosol generating device for repeated use .
[003] It is an objective of the invention to provide an intensified operation of this type of electrical system.
[004] According to a first aspect of the present description, an electrical system is provided comprising a primary device and a secondary device, wherein the primary device comprises: a source of electrical energy; a cavity configured to receive the secondary device; at least one electrical contact within the cavity configured to contact a corresponding contact on the secondary device, when the secondary device is in the cavity, the at least one electrical contact being electrically connected to the electrical power source; and a movable cover between a first position to keep the secondary device in contact with at least one electrical contact, and a second position in which the secondary device is free to move away from contact with at least one electrical contact.
[005] Such a system advantageously allows reliable and efficient charging of the secondary device through the guaranteed electrical contact between the primary device and the secondary device.
[006] The primary device is preferably configured to prevent power supply to the secondary device through at least one electrical contact, when the cover is not in the first position. To avoid supplying power to the secondary device when the cover is not in the first position, the use of the secondary device, when power is being supplied to the secondary device, can be avoided.
[007] The primary device can be configured to avoid power supply to the secondary device, ensuring a very high resistance between at least one electrical contact and the secondary device, when the cover is not in the first position. The primary device can be configured to avoid contact between at least one electrical contact and the secondary device, when the cover is not in the first position. The primary device can be configured to prevent a complete electrical connection being made between the primary device and the secondary device, when the cover is not in the first position. By complete electrical connection, it is meant that electricity is able to flow between the primary device and the secondary device.
[008] In an alternative, the cap preferably comprises a means of preventing power supply to the secondary device when the cap is not in the first position. Preferably, the energy prevention means comprises a switch. The switch can be a physical contact switch adapted to be closed when the cover is in the first position. The switch is in electrical connection with the power supply, and allows the power supply to the secondary device, when in the closed position. The switch is a blade switch, in which the blade switch is provided in the primary device adjacent to the cavity opening, and the activating magnet is provided in the cover. The magnet is positioned on the cover in such a way that, when the cover is in the first position, the magnet activates the blade switch allowing the power supply to the secondary device. Alternatively, a Hall Effect transducer can be used. In this alternative, the Hall Effect transducer is positioned in the primary device adjacent to the cavity opening. A magnet is provided in the cover in such a way that, when the cover is in the first position, the magnet activates the Hall effect transducer, enabling the supply of energy to the secondary device.
[009] Preferably, in the first position, the cover pushes the secondary device in contact with at least one electrical contact. By pushing the secondary device into contact with at least one electrical contact, the electrical resistance, between the contact and the secondary device, can be significantly reduced, thereby enabling the supply of energy to the secondary device.
[0010] As used here, the term ‘boosting’ or ‘boosting’ means that an energy is applied by one component to another component.
[0011] As used here, the term 'resilient element' refers to an element that can be deformed or deflected by an applied energy, but is able to return to its original position or state after the applied energy is removed. When a resilient element is deformed or deflected by an energy applied by a component moving towards the resilient element, the resilient element generates reactive energy that propels the component away from the resilient element. Examples of resilient elements include coil springs and cantilever springs.
[0012] Preferably, the electrical system still comprises at least one resilient element configured to propel the secondary device towards the cover, when the secondary device is positioned in the cavity. Preferably, the at least one resilient element is configured to propel the secondary device towards the lid, when the lid is in the first position. Preferably, the at least one resilient element is configured not to propel the secondary device towards the lid, when the lid is in the second position. The resilient element can be configured to propel the secondary device at least partially out of the cavity, when the lid is in the second position. By pushing the secondary device, at least partially, out of the cavity, the secondary device can be more easily removed from the primary device. The at least one electrical contact is preferably the at least one resilient element.
[0013] Preferably, the cavity is an elongated cavity extending from the top of the primary device. The length of the cavity, from its open end to its closed end, is preferably at least not as long as the secondary device.
[0014] Preferably, the electrical system still comprises a plurality of electrical contacts electrically connected to the source of electrical energy. The electrical system can comprise two electrical contacts, a first electrical contact being connected to the positive terminal of the power supply, and a second electrical contact being connected to the negative terminal of the power supply.
[0015] In an additional alternative, the power supply is prevented by providing a resilient mobile electrical contact, and a non-mobile electrical contact. The mobile electrical contact is configured to prevent the second non-mobile contact from engaging with the secondary device, when the cover is not in the first position. This prevents the formation of a complete electrical connection until the cover is closed.
[0016] The electrical contacts are preferably made of metal. Preferably, the metal used to make the electrical contacts is copper-beryllium. Preferably, at least a portion of the electrical contact is nickel-plated gold.
[0017] Preferably, the source of electrical energy comprises a rechargeable battery. Preferably, the primary device comprises means for receiving external electrical energy to recharge the rechargeable battery.
[0018] Preferably, the electrical supply device is configured to supply power to the secondary device in an appropriate manner to recharge a secondary battery in the secondary device.
[0019] The first position of the lid is preferably a closed position, and the second position of the lid is preferably an open position. When the lid is in a closed position, access to the secondary device is preferably substantially avoided. In addition, when the lid is in the closed position, preferably, the secondary device cannot be removed from the primary device.
[0020] Preferably, the primary device still comprises a housing, in which the lid is engaged for the housing in both the first and the second position.
[0021] The housing preferably comprises a front wall, a back wall, a back wall, a top wall, a first side wall and a second side wall.
[0022] The terms "front", "back", "top", "bottom", "side", "top", "bottom", "left", "right" and other terms used to describe relative positions of components of the primary device and secondary device, refer to the primary device in a vertical position with a cavity opening configured to receive the secondary device at the top end.
[0023] The term "longitudinal" refers to a direction from the bottom to the top or vice versa. The term "transverse" refers to a direction perpendicular to the longitudinal direction.
[0024] The primary device may be a substantially rectangular parallelepiped comprising two wider walls, spaced apart by two narrower side walls and top and bottom walls. The secondary device is preferably elongated.
[0025] The lid is preferably a hinged lid. Preferably, the hinge extends along the top of the housing from the front wall to the back wall. The hinge may comprise a spring configured to retain the cover in the first position. The joint may also comprise a damper configured to cushion the lid movement, when the lid is moved from the second position to the first position. Alternatively, the hinge may comprise a spring configured to hold the cap in the second position. In this alternative, the lid is preferably provided with means for retaining the lid in the first position, the retaining means being configured to provide sufficient energy to overcome the energy applied to the lid by the spring.
[0026] The retaining means may comprise at least one magnet and at least one corresponding ferrous element. The at least one magnet, being provided in the housing of the primary device, and the ferrous element being provided in the cap. Alternatively, the retaining means may be an arrangement-type hitch.
[0027] The joint cover can form the entire top of the housing. In this alternative, the hinge can be internal to the lid, and be an adjacent side wall of the housing.
[0028] Preferably, the secondary device is an electrically heated aerosol generating device. The aerosol generating device is designed to receive an aerosol generating article and be safe for the user during the smoking experience. A power supply is preferably provided in the secondary device and is adapted to heat the substrate, forming the aerosol to operate at the temperature before the generation of the aerosol begins. The energy supply in the secondary device is also adapted to maintain the temperature of the aerosol-forming substrate during aerosol generation. The source of electrical power in the primary device is preferably used to charge the secondary power supply, during a charging mode, when the secondary device is not in use.
[0029] The secondary device, in the form of an electrically heated aerosol generating device, is preferably of a size similar to, or slightly larger than, a lit cigarette. In this way, the secondary unit can be held between the user's fingers in a similar way to that of the lit cigarette.
[0030] Preferably, the secondary device comprises an electric heating element, and the primary device is configured to be able to supply energy to the secondary device when the lid is in the first position to heat the electric heating element to thermally release organic materials adhering to, or deposited on, the heating element. In use, an aerosol generating article is provided in the secondary device, in the form of an aerosol-forming substrate. When the aerosol generating article is removed from the secondary device, it can leave a residue in the heater of the secondary device, and by heating the electric heater to a temperature sufficient to release that organic residue, the heater can be cleaned. This operation can be performed by the user by activating a switch on the primary device, or after a predetermined number of charges from the secondary device, or another.
[0031] As used herein, an 'aerosol generating device' refers to a device that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol forming substrate may be part of an aerosol generating article, for example, part of a smoking article. An aerosol generating device may comprise one or more components used to supply energy from an energy supply to an aerosol-forming substrate to generate an aerosol. For example, an aerosol generating device can be a heated aerosol generating device. An aerosol generating device can be an electrically heated aerosol generating device or a gas heated aerosol generating device. An aerosol generating device may be a smoking device that interacts with an aerosol-forming substrate of an aerosol-generating article to generate an aerosol that is directly inhaled into the user's lungs through the user's mouth.
[0032] As used herein, the term 'aerosol-forming substrate' refers to a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds can be released by heating the aerosol-forming substrate. As an alternative to heating or combustion, in some cases, volatile compounds can be released by a chemical reaction or by a mechanical stimulus, such as ultrasound. An aerosol forming substrate can be solid or liquid or comprise both components, solid and liquid. An aerosol-forming substrate can be adsorbed, coated, impregnated or otherwise loaded onto a vehicle or support. An aerosol-forming substrate may conveniently be part of an aerosol-generating article or smoking article.
[0033] An aerosol-forming substrate may comprise nicotine. An aerosol-forming substrate may comprise tobacco, for example, it may comprise a tobacco-containing material, containing volatile tobacco flavor compounds, which are released from the aerosol-forming substrate upon heating. In preferred embodiments, an aerosol-forming substrate may comprise homogenized tobacco material, for example, reconstituted tobacco. An aerosol-forming substrate can comprise at least one aerosol former, such as propylene glycol or glycerin.
[0034] As used herein, the terms 'aerosol generating article' and 'smoking article' refer to an article comprising an aerosol-forming substrate that is capable of volatile release compounds that can form an aerosol. For example, an aerosol generating article may be a smoking article that generates an aerosol that is directly inhaled into the user's lungs through the user's mouth. An aerosol-generating article may be disposable. The term ‘aerosol generation article’ is generally used hereinafter.
[0035] Preferably an aerosol generating article is a heated aerosol generating article, which is an aerosol generating article comprising an aerosol forming substrate, which is intended to be heated instead of combustion in order to to release volatile compounds that can form an aerosol. The aerosol formed by heating the aerosol-forming substrate may contain less harmful constituents than would be produced by combustion or pyrolytic degradation of the aerosol-forming substrate. An aerosol generating article may be, or may comprise, a tobacco stick.
[0036] The presence of organic material or residue in a heating element can impair the user's experience when consuming aerosol-generating articles such as smoking articles. Thus, it may be preferred that the heater or heating elements of an aerosol generating device (i.e., a secondary device) are regularly cleaned. The primary device or the aerosol generating device may comprise an indicator that warns the user that the device must be subjected to a cleaning cycle. A controller located on the aerosol generating device or on the primary device, can determine when the device has to undergo a predetermined number of smoking cycles, without being subjected to a cleaning cycle, and can activate the indicator. If the user does not activate a cleaning cycle within a predetermined number of smoking cycles after the indicator has been activated, the user may be prevented from consuming additional items before a cleaning cycle is carried out. Such a cleaning cycle may need to be manually activated or may occur automatically when the aerosol generating device is loaded into the primary device after the cleaning need has been determined. By avoiding the operation of the aerosol generating device, when there is a need for cleaning, a more pleasant experience for the user can be distributed more consistently.
[0037] Preferably, the lid comprises at least one opening allowing the material to escape from the cavity, when the secondary device is in the cavity and the lid is in the first position. The opening is preferably configured to let out the released organic material. Providing at least one opening in a lid advantageously allows ventilation of the cavity, within the primary device, to reduce the formation of deposits.
[0038] Preferably, the secondary device is configured to operate in at least three modes. The at least three modes are preferably a way of charging, a way of cleaning, and a way of operating. The charging mode and the cleaning mode are preferably accessible only when the secondary device is inside the primary device and the lid is in the first position. The mode of operation, that is to say to generate aerosol, is preferably available only when the secondary device is not within the primary device.
[0039] Preferably, the secondary device comprises a rechargeable battery and the primary device is configured to supply power to the secondary device, in an appropriate manner to recharge the rechargeable battery in the secondary device, when the secondary device is in contact with at least an electrical contact.
[0040] Preferably, the secondary power supply is chargeable by the primary power supply, during charging mode, so that the secondary power supply is sufficiently charged to maintain the temperature of the aerosol forming substrate substantially at the temperature operational during smoking mode. If an ideal temperature is not reached afterwards, the quantity and quality of an aerosol generated during the operation of the device can be decreased. For example, different proportions of volatile elements can be generated when the heating element heats an aerosol-forming substrate to a lower temperature, compared to when the substrate is heated to an ideal temperature, and this can alter the flavor of the aerosol. In order to deliver a more ideal and consistent user experience, it may be preferred that the secondary device is operated only when the secondary power supply is in a fully charged condition. In the fully charged condition, the secondary energy supply will always be able to heat the aerosol-forming substrate to an ideal temperature. Since any operation of the secondary device will consume power from the secondary power supply, it may be preferred that the secondary device needs to be recharged before each operation. For example, an aerosol generating device may be required to be refilled after each act before another smoking article is consumed.
[0041] Insufficient charge can also result in an unsatisfactory user experience if the secondary device no longer has sufficient charge to heat the aerosol forming substrate for a period of time sufficient to exhaust or substantially empty any aerosol substrate. that can be formed. Thus, in one embodiment, the secondary device prevents the user from starting the operation of the device, unless sufficient energy is available to complete an aerosol generation cycle. For example, if the aerosol being generated is a smoking article including a tobacco-based aerosol forming substrate, the secondary device may not allow a smoking experience, unless sufficient energy is present to maintain the operating temperature for at least 6 minutes.
[0042] Preferably, electricity supply from the primary power supply to the at least one heating element, during a preheat mode, is controlled by the secondary circuit on the secondary device. The supply of electricity from the primary power supply, during charging mode, to charge the secondary power supply, can be controlled by the secondary circuit on the secondary device.
[0043] The secondary device can be locked into the cavity of the primary device in such a way that only a secondary device compatible with the primary device can be inserted into the cavity. For the purpose of enclosing the secondary device for the cavity of the primary device, the cavity can be provided with a specific non-regular shape, and the secondary device can be provided with a corresponding non-regular shape. In addition, to ensure that the secondary device is inserted into the cavity in the correct orientation, the non-regular shape is preferably non-rotationally symmetrical. As such, the secondary device can be inserted into the cavity in one orientation only.
[0044] The primary device can also comprise at least one contact configured to transfer data between the primary device and the secondary device. Preferably, the primary device still comprises at least two contacts configured to transfer data between the primary device and the secondary device. The primary device is preferably configured to only transfer data to, or receive data from, the secondary device when the cover is in the first position.
[0045] The at least one data transfer contact is preferably a resilient element. Preferably, the at least one data transfer contact is configured to avoid power supply to the secondary device, when the cover is not in the first position. The at least one resilient data transfer contact is preferably moved from a first neutral position, when the cover is in the second position, where the at least one electrical contact power supply is not engaged with the secondary device, to a second position deflected when the cover is in the first position, where the at least one electrical data contact and the at least one electrical power supply contact are both in electrical contact with the secondary device.
[0046] Data can be communicated between both the primary and secondary device, as well as from the primary device to a computer interface capable of being read by a computer, or another electronic device capable of transferring data to a computer or to the internet. Preferably, the data connection operates under an interface standard. An interface standard is a standard that describes one or more functional characteristics, such as a code conversion, line assignments, or protocol compatibility, or physical characteristics, such as electrical, mechanical, or optical characteristics, necessary to allow an exchange information between two or more systems or pieces of equipment. Examples of interface standards suitable for connecting communications include, but are not limited to, the Recommended Standard 232 (RS-232) family of standards; USB; Bluetooth; FireWire (a trade name of Apple, Inc for its IEEE 1394 interface), IrDA (Infrared Data Association - a communications standard for short-range data exchange using infrared light); Zigbee (a specification based on the IEEE 802.15.4 standard for wireless personal area networks) and other Wi-Fi standards.
[0047] In accordance with another aspect of the present description, an electrical system is provided comprising a primary device and a secondary device, wherein the primary device comprises: a source of electrical energy; a cavity configured to receive the secondary device; at least one electrical contact within the cavity configured to contact a corresponding contact on the secondary device, when the secondary device is in the cavity, the at least one electrical contact being electrically connected to the electrical power source; and a movable cap between a first position for holding the secondary device in the cavity, and a second position in which the secondary device is free to exit the cavity, where the cap comprises at least one opening that allows the material to escape from the cavity , when the cover is in the first position.
[0048] The cover can be held in the first position by mechanical means, such as a fastener, or by means of a magnetic latch. The cover can be retained in the first position by means of a spring-loaded closing energy. For example, the cover may have a hinge that incorporates a locking mechanism. It may be preferable for the lid to have a hinge that incorporates a cushioning mechanism to help prevent damage to the lid, while the lid moves between the first position and the second position. The cover can therefore have a hinge that incorporates a rotary damper or a barrier damper mechanism.
[0049] According to a still further aspect of the present description, an aerosol generating system comprising an aerosol forming substrate and an electrical system as described herein is provided. The secondary device is an aerosol generating device that is configured to receive the aerosol-forming substrate. The cap is prevented from moving to the first position, when the secondary device is in the cavity and the aerosol forming substrate is received in the secondary device.
According to a still further aspect of the present description, an aerosol generating device is provided, comprising a heating element for heating an aerosol-forming substrate to form an aerosol; a rechargeable battery attached to the heating element and configured to supply energy to the heating element; and a controller coupled to the rechargeable battery, the controller configured to prevent activation of the heating element, unless the rechargeable battery is charged above the level of the predetermined limit. The elements comprised in the aerosol generating device are preferably retained within a housing which also defines a substrate receiving chamber to receive and locate an aerosol forming substrate in the vicinity, or contact with the heating element. It may be advantageous for the aerosol forming substrate to be a component element of an aerosol generating article configured to be received in the substrate receiving cavity.
[0051] In an aerosol generation device, the controller is configured to prevent the heating element from operating for a predetermined period, after the heating element has been previously activated. Alternatively, or in addition, the controller can be configured to prevent the heating element from operating based on a rechargeable battery charge level or based on an amount of energy consumption following activation of the heating element. As discussed above, the quantity and quality of an aerosol, generated during operation, can be compromised if the charge levels of the rechargeable battery are not sufficient to apply a predetermined thermal cycle to the aerosol-forming substrate.
[0052] The primary device may include a display (for example, a digital display) indicating information for the user. For example, the display can indicate the consumption of the smoking article, energy use or other information. The display can also indicate when the secondary power supply is sufficiently charged to be used to consume a smoking article.
[0053] According to a still further aspect of the present description, an aerosol generating device is provided comprising: a heating element; a power source coupled to the heating element and configured to supply energy to the heating element; and a controller coupled to the heating element, the controller configured to control the power supply to the heating element, in a first way to perform an aerosol generation cycle, and a second way to perform a cleaning cycle, the controller further configured to monitor the operation of the device and to prevent power supply in a first mode following the performance of the limit number of consecutive aerosol generation cycles without performing a cleaning cycle. The elements comprised in the aerosol generating device are preferably kept within a housing, which also defines a substrate receiving chamber to receive and locate an aerosol forming substrate in close proximity or in contact with the heating element. It may be advantageous for the aerosol forming substrate to be a component element of an aerosol generating article, configured to receive in the cavity receiving substrate.
The aerosol-forming substrate preferably comprises a tobacco-containing material, containing volatile tobacco flavor compounds that are released from the substrate upon heating. Alternatively, the aerosol-forming substrate may comprise a non-tobacco material. Preferably, the aerosol forming substrate further comprises an aerosol former. Examples of suitable aerosol builders are glycerin and propylene glycol.
[0055] The aerosol forming substrate can be a solid substrate. The solid substrate may comprise, for example, one or more of: powder, granules, pellets, pieces, spaghetti, strips or leaves containing one or more of: herb leaf, tobacco leaf, tobacco streak fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco and expanded tobacco. Optionally, the solid substrate can contain volatile tobacco or non-tobacco flavor compounds, to be released by heating the substrate. Optionally, the solid substrate can be provided in, or embedded in, a thermally stable vehicle. The vehicle can take the form of powder, granules, pellets, pieces, spaghetti, strips or leaves. Alternatively, the vehicle can be a tubular vehicle having a thin layer of the solid substrate deposited on its inner surface, or on its outer surface, or on both its inner and outer surfaces. Such a tubular vehicle can be formed, for example, of a paper, or a paper-like material, a non-woven carbon fiber material, a low-mass open-mesh wire mesh, or perforated metal laminated paper or any other matrix of thermally stable polymer. The solid substrate can be deposited on the vehicle surface in the form of, for example, a sheet, foam, gel or slurry. The solid substrate can be deposited on the entire surface of the vehicle, or alternatively, it can be deposited in a pattern in order to provide a non-uniform flavor distribution during use. Alternatively, the vehicle can be a non-woven fabric or bundle of fibers into which the tobacco components have been incorporated. Nonwoven fabric or bundle of fibers may comprise, for example, carbon fibers, natural cellulose fibers, or fibers derived from cellulose.
[0056] The aerosol forming substrate may be a liquid substrate and the smoking article may comprise means for retaining the liquid substrate. The aerosol forming substrate can alternatively any other type of substrate, for example, a gas substrate, or any combination of various types of substrate.
The primary unit may include storage means for at least one aerosol generating article, such as a smoking article including a tobacco aerosol forming substrate. The storage means can include storage for used smoking articles, unused smoking articles or both. This is advantageous as the primary unit and the secondary unit together provide all the components required for smoking.
[0058] One aspect may provide an aerosol generating system comprising an aerosol generating device for consumption of an aerosol generating article, the aerosol generating device comprising a heating element and a rechargeable energy supply to energize the heating element, and a charging device for coupling to the aerosol generating device to recharge the power supply and cleaning the heating element, in which the system is configured to avoid the consumption of an aerosol generating article, when the aerosol generating device is coupled to the charging device. The aerosol generating device can be any aerosol generating device or any secondary device as described here. The charging device can be any charging device or primary device as described here. The aerosol generating article can be any aerosol generating article or smoking article as described here. The system may comprise a mechanical means to prevent consumption of an aerosol generating article, when the aerosol generating device is coupled to the loading device. For example, it may not be possible to activate the heating element when the aerosol generating device is coupled to the charging device, unless the aerosol generating device is included within the charging device by a lid. The lid is not able to close if the aerosol generating device is coupled to an aerosol generating article. The system may comprise electrical or software means to prevent consumption of an aerosol generating article, when the aerosol generating device is coupled to the charging device. For example, sensors can detect the presence of an aerosol generating article when the aerosol generating device is coupled to the charging device and a controller can then prevent the heating element from being activated.
[0059] One aspect may provide an aerosol generating device comprising a heating element and a power supply to enable the heating element, wherein the device is configured to prevent activation of the heating element, unless the supply of energy has a predetermined level greater than the available load to strengthen the heating element. It may be preferred that this heating element activation occurs only when the power supply is fully charged. The aerosol generating device can be any aerosol generating device, or any secondary device as described here.
[0060] One aspect may provide a method of delivering a consistent user experience to a consumer of an aerosol generating article, the article being consumed by heating in an aerosol generating device, comprising a heating element and a supply of energy to energize the heating element, the method comprising the steps of, determining the charge level of the energy supply, and triggering the heating element only, if the available charge exceeds a predetermined limit. The aerosol generating device can be any aerosol generating device or any secondary device as described here. The aerosol generating article can be any aerosol generating article or smoking article as described here.
[0061] One aspect may provide an aerosol generating system comprising an aerosol generating device for consumption of an aerosol generating article, the aerosol generating device comprising a heating element supplying rechargeable energy to power the cooling element. heating, and a charging device to attach to the aerosol generating device to recharge the power supply and clean the heating element, in which the system is configured in such a way that the user is prevented from consuming more than one number predetermined amount of articles generating aerosol without cleaning the heating element when the aerosol generating device is coupled to the loading device.
[0062] As used here, means more function characteristics can be expressed alternatively in terms of their corresponding structures.
[0063] Any characteristic related to one aspect can be applied to other aspects, in any appropriate combination. In particular, aspects of methods can be applied to aspects of the apparatus, and vice versa. In addition, any, any or all of the characteristics in one aspect can be applied to any, some or all of the characteristics in any other aspect, in any appropriate combination.
[0064] It should also be noted that particular combinations of the various aspects described and defined in any aspects of the invention, can be implemented or supplied or used independently.
[0065] The invention will be further described, by way of example only, with reference to the accompanying drawings in which: Figure 5 (a) and 1 (b) show a primary device and a secondary device respectively of an electrical system; Figure 6 shows the secondary device of Figure 1 (b) housed within the primary device of Figure 1 (a); Figure 7 shows a detailed view of an electrical contact of the primary unit shown in Figures 1 (a), of 2; and Figure 8 shows a top view of the primary device.
[0066] Figure 1 (a) shows a primary device 100. The primary device 100 in this example is a charging and cleaning unit for an electrically heated heating system. Figure 1 (b) shows a secondary device 102. The secondary device 102 in this example is an electrically heated aerosol generating device adapted to receive a smoking article 104, comprising an aerosol-forming substrate. Primary device 100 comprises a primary battery 106, control electronics 108, and electrical contacts 110 configured to supply electrical power to the secondary device, from battery 106, when the secondary device is in connection with electrical contacts 110. The device primary is configured to charge the secondary device using battery 106. The electrical contacts 110 are provided adjacent to the bottom of a cavity 112. The cavity is configured to receive the secondary device 102. A cap 114 is provided that is configured to secure the device secondary 102 inside the cavity 112 of the primary device 100. The components of the primary device 100 are housed within the housing 116. A cover 114 is coupled to the housing 116 by the hinge 118. The operation of the cover is described in further details below.
[0067] In addition, primary device 100 is provided with a series of three indicators 120, 122 and 124. Indicator 120 is provided to indicate the level of charge remaining in primary battery 106. Indicator 120 is configured to indicate the percentage of the remaining charge in the primary battery. For example, 100% would indicate that battery 106 is fully charged, and 50% would indicate that battery 106 is half charged.
[0068] The second indicator 122 is provided to indicate that the secondary device 102 is fully charged, and ready to be used to generate an aerosol. Indicator 122 only indicates this state of clearance once the secondary device is able to provide enough energy to provide the user with a complete smoking experience; for example, enough energy to aerosolize the entire aerosol forming substrate 104, or enough energy to generate a predetermined number of puffs. In this specific embodiment, the secondary device 102 cannot be operated unless the rechargeable battery 126 is fully charged.
[0069] The third indicator 124 is provided to indicate that the secondary device is being cleaned. The cleaning operation is described in further detail below.
[0070] The secondary device 102 comprises a rechargeable battery 126, secondary electronic controls 128 and electrical contacts 130. As described above, the rechargeable battery 126 of the secondary device 102 is configured to receive a power supply from the primary battery 106 when the electrical contacts 130 are in contact with the electrical contacts 110 of the primary device 100 and the cover is in the closed position. Secondary device 102 further comprises a cavity 132 configured to receive the aerosol generating article 104. A heater 134, in the form of, for example, a blade heater, is provided at the bottom of cavity 132. In use, the user activates secondary device 102, and power is supplied from battery 126 through electronic controls 128 to heater 134. The heater is heated to a standard operating temperature that is sufficient to generate an aerosol from the aerosol-forming substrate of the aerosol generating article 104. Secondary device components 102 are housed within housing 136.
[0071] The primary device is provided with four electrical contacts 110, two to supply power to the secondary device, and two to communicate data between the primary device and the secondary device. The data connection is configured to download data from the secondary device such as usage statistics, operational data information and the like. In addition, the data connection is configured to transfer data from the primary device to the secondary device such as operational protocols. Operational protocols may include power supply profiles to be used when power is supplied from the secondary power supply to the heater. The data can be communicated, from the secondary device 102, to the primary device 100 and stored in, for example, electronic controls 108. The data can then be communicated out of the primary device 100 via communication port 138 which can be connected to electronic controls 108.
[0072] Figure 2 shows the secondary device 102 housed within the cavity of the primary device 100. The lid 114 is shown in the closed position. In that closed position the cover is configured to act on the secondary device 102 in such a way that a good electrical connection is made between the primary device and the secondary device. As can be seen, the electrical contacts 130 of the secondary device are engaged with the electrical contacts 110 of the primary device. The electrical contacts 110 of the primary device are configured in such a way that they apply power to the secondary device when the cover is in the closed position. The electrical contacts 110 form resilient elements and, any opposite energies absent from the secondary device, are in a neutral position such that they are displaced from the bottom surface of the cavity 112; see Figure 1 (a).
[0073] The dimensions of the primary device are such that the lid will not close if a smoking article 104 is housed within the secondary device. In this way, the secondary device cannot be charged or cleaned when a smoking article is housed, as the lid cannot be moved to the closed position that would allow energy to be supplied to the secondary device. This can prevent the user from using the secondary device to generate an aerosol when the secondary device is being loaded or cleaned.
[0074] The lid 114 is provided with means for maintaining the lid in the closed position. The retaining means provide sufficient energy in such a way that the cap acts on the secondary device to deflect the electrical contacts from the position shown in Figure 1 (a) to the engaged position shown in Figure 2. The retaining means is a spring within the joint 118. Alternatively, or in addition, the cover may be provided with ferrous elements adapted to engage with magnets provided in the housing of the primary device.
[0075] Figure 3 shows a detailed view of the electrical contact 110 of the primary unit. As can be seen, the electrical contact 110 is in the form of a leaf spring that allows the electrical contact 110 to be resilient in order to provide sufficient energy for the secondary device, when the cover is in the closed position, to ensure a good electrical connection between the primary device and the secondary device. The electrical contact 110 is mounted to the primary device by the support 300. The support 300 is configured and such that the end of the extension 302 of the electrical contact remains substantially static, when the secondary device is engaged with the electrical contact 110, at the end of the contact 304 and deviated from the neutral position shown in Figure 1 (a). The extension end 302 is connected to the electronic controls via electrical wires, and thereby ensuring that the extension end 302, remaining substantially static during use, reduces the possibility that the connection will fail due to fatigue. As described above, the primary device is provided with four such electrical contacts; two for electricity, and two for data communication. The four electrical contacts are configured to provide a combined power of approximately 5N for the secondary device, when the secondary device is in the cavity and the cover is in the closed position. The cap retaining the medium is thus configured to provide approximately 7.5N of retention energy between the housing and the cap. The additional energy is provided to reduce the possibility of a lid opening if the lid is accidentally knocked by the user while loading, or cleaning, the secondary device.
[0076] Although a specific modality of the electrical contacts is provided here, it will be obvious to the person skilled in the art that any configuration of the electrical contacts can be used.
[0077] As described above, the primary device is also configured to perform a cleaning operation on the secondary device. The cleaning operation involves supplying sufficient electrical power to the secondary device to enable the heater 134 to be heated above its standard operating temperature to a cleaning temperature. The cleaning temperature is sufficient to release any remaining aerosol-forming substrate that may remain attached to the blade heater after the smoking article 104 has been removed from the secondary device 102. As shown in Figure 4, the cap 114 comprises a vent 400, which is configured to allow the released aerosol-forming substrate to leave the cavity, for example, in the form of an aerosol such as smoke. During the cleaning operation, the third indicator 124 is illuminated to inform the user that the secondary device is being cleaned. During this cleaning operation the user can be prevented from opening the cover to remove the secondary device.
[0078] Naturally, it should be understood that the specification is not intended to be restricted to the details of the above modalities which are described by way of example only.
