Description

[Technical field]

[0001]

[0001] The present invention relates to smoking substitution systems, and particularly, but not exclusively, to smoking substitution systems including devices, and aerosol-forming articles. [Background technology]

[0002]

[0002] Smoking tobacco is generally regarded as exposing the smoker to potentially harmful substances, which are generally believed to be produced in significant quantities through the burning of tobacco and / or the heat caused by the burning of tobacco, as well as through the constituents of burnt tobacco in the tobacco smoke itself.

[0003]

[0003] A conventional combustible smoking article, such as a cigarette, typically includes a cylindrical tobacco rod comprising strips of tobacco surrounded by a wrapper, and typically also includes a cylindrical filter axially aligned in abutting relationship with the rolled tobacco rod. The filter typically includes a filtration material circumscribed by a plug wrap. The rolled tobacco rod and the filter are held together by a rolled strip of tipping paper that circumscribes the entire length of the filter and adjacent portions of the rolled tobacco rod. This type of conventional cigarette is used by lighting the end opposite the filter to burn the tobacco rod. The smoker receives mainstream smoke into his or her mouth by drawing on the mouth or filter end of the cigarette.

[0004]

[0004] Combustion of organic materials, such as tobacco, is known to produce tar and other potentially harmful by-products. To avoid smoking tobacco, various smoking substitution systems (or "substitute smoking systems") have been proposed.

[0005]

[0005] Such smoking substitution systems can form part of a nicotine replacement therapy aimed at people wishing to quit smoking and overcome their dependence on nicotine.

[0006]

[0006] Smoking substitution systems include electronic systems that allow a user to simulate the act of smoking by producing an aerosol (also called "vapor") that is drawn into the lungs through the mouth (inhaled) and then exhaled. The inhaled aerosol typically has nicotine and / or flavorings without or with fewer odors and health risks associated with traditional smoking.

[0007]

[0007] Generally, smoking substitution systems are intended to provide a substitute for the habitual behavior of smoking while providing users with an experience and satisfaction similar to that experienced with traditional smoking and combustible tobacco products. Some smoking substitution systems use smoking substitution articles (also called "consumables") that are designed to resemble traditional cigarettes and are cylindrical in shape with a mouthpiece at one end.

[0008]

[0008] The popularity and use of smoking substitution systems has grown rapidly over the past few years. Although originally marketed as aids to assist habitual smokers wishing to quit smoking tobacco, consumers increasingly view smoking substitution systems as a desirable lifestyle accessory.

[0009]

[0009] There are several different categories of smoking proxy systems, each of which utilizes a different smoking proxy approach.

[0010]

[0010] One approach for smoking substitution systems is the so-called heated tobacco ("HT") approach, in which tobacco (not "e-liquid") is heated or warmed to release vapor. HT is also known as "heat-not-burn" ("HNB"). The tobacco may be leaf tobacco or reconstituted tobacco. The vapor may contain nicotine and / or flavorings. In the HT approach, the intention is that the tobacco is heated without being burned, i.e., the tobacco does not undergo combustion.

[0011]

[0011] A typical HT smoking substitution system may include a device and a consumable. The consumable may include tobacco material. The device and consumable may be configured to be physically coupled together. In use, heat may be applied to the tobacco material by a heating element of the device, and airflow through the tobacco material causes components in the tobacco material to be released as vapor. The vapor may also be formed from a carrier in the tobacco material (which may include, for example, propylene glycol and / or vegetable glycerin), as well as volatile compounds released from the tobacco. The released vapor may be entrained in the airflow drawn through the tobacco.

[0012]

[0012] As the vapor passes through the consumable (entrained in the airflow) from the point of evaporation to the outlet of the consumable (e.g., the mouthpiece), the vapor cools and condenses to form an aerosol for inhalation by the user. The aerosol typically contains volatile compounds.

[0013]

[0013] In HT smoking substitute systems, it is believed that heating, as opposed to burning, tobacco material results in fewer or lower amounts of more harmful compounds that are typically produced during smoking. As a result, the HT approach can reduce odor and / or health risks that can result through tobacco burning, tobacco combustion, and pyrolytic degradation.

[0014]

[0014] Another approach is the so-called "vaping" approach, in which a vaporizable liquid, usually called (and referred to herein as) "e-liquid," is heated by a heating device (referred to herein as an electronic cigarette or "e-cigarette" device) to produce an aerosol vapor that is inhaled by the user. E-liquid typically includes a base liquid, as well as nicotine and / or flavorants. Thus, the resulting vapor typically also contains nicotine and / or flavorants. The base liquid may include propylene glycol and / or vegetable glycerin.

[0015]

[0015] A typical e-cigarette device includes a mouthpiece, a power source (usually a battery), a tank for containing e-liquid, and a heating device. In use, electrical energy is supplied from the power source to the heating device, which heats the e-liquid to produce an aerosol (or "vapor"), which is inhaled by the user through the mouthpiece.

[0016]

[0016] E-cigarettes can be configured in a variety of ways. For example, there are "closed system" vaping smoking substitute systems, which typically have a sealed tank and a heating element. The tank is pre-filled with e-liquid and is not intended to be refilled by the end user. Some closed system vaping smoking substitute systems include a body including a power source, which is configured to be physically and electrically coupled to a consumable including a tank and a heating element. In this way, when the tank of the consumable is emptied, the consumable is disposed of. The body can be reused by connecting to a new replacement consumable. Some other closed system vaping smoking substitute systems are completely disposable and are intended for one-time use only.

[0017]

[0017] There are also "open" vaping smoking replacement systems, which typically have a tank configured to be refilled by the user. In this way, the entire device can be used multiple times.

[0018]

[0018] Improved designs of smoking substitution systems are needed to enhance the user experience and provide users with more versatility.

[0019]

[0019] The present disclosure has been devised in view of the above problems. Summary of the Invention

[0020]

[0020] Most generally, the present invention relates to a smoking substitution device capable of operating with both e-cigarettes and non-combustion heating consumables.

[0021]

[0021] According to the present invention, there is provided a smoking substitution device including one or more heaters for heating consumables and a controller configured to control the one or more heaters according to first and second heating modes, the first heating mode being for heating non-combustion heated consumables and the second heating mode being for heating e-cigarette consumables.

[0022]

[0022] By providing a smoking substitution device capable of operating in two different heating modes, the device can accommodate multiple consumable types. This means that a user does not need two different devices to accommodate non-combustion heating consumables and e-cigarette consumables (i.e., the device provides a mutual vaping experience). As discussed above, non-combustion heating consumables generally include solid tobacco leaves or reconstituted tobacco, and e-cigarette consumables include e-liquids (i.e., liquids) formed from a base liquid and nicotine and / or flavorants. In this regard, non-combustion heating consumables generally include a solid aerosol-forming substrate, and e-cigarette consumables generally include an aerosol-forming liquid contained, for example, in a tank.

[0023]

[0023] Optional features are described below, which may be applied alone or in any combination with any aspect.

[0024]

[0024] The first heating mode and the second heating mode may be operated by a single heater. That is, the controller may control the single heater differently depending on whether the heating mode is the first heating mode or the second heating mode. This may simplify maintenance of the device and minimize the cost of making the device.

[0025]

[0025] The heater may include first and second heating tracks for heating the consumable. The first and second tracks may be configured to heat to different temperatures (e.g., when the same voltage is applied to both tracks). The first and second tracks may be configured to heat at different rates (e.g., when the same voltage is applied to both tracks). The first and second tracks may be located in different regions of the heating element. The first and second tracks may be different shapes and / or sizes. The first and second tracks may be formed from different materials. The first and second tracks may be configured to have different impedances. Both tracks may be electrically connected to the same power source. Both tracks may be electrically connected to each other.

[0026]

[0026] The first heating track may be configured to directly contact the aerosol-forming substrate of the consumable. The second heating track may be configured to contact a heating element of the consumable, and thus the second heating track may be configured to indirectly heat the aerosol-forming substrate of the consumable.

[0027]

[0027] In a first heating mode, the first track may be active and the second track may be inactive. In a second heating mode, the first track may be inactive and the second track may be active. In other words, in each of the two heating modes, only one of the tracks may be active. Thus, each track may be configured to operate in one of the two heating modes. For example, the first track may be configured to heat a non-combustion heating consumable and the second track may be configured to heat an e-cigarette consumable (or vice versa).

[0028]

[0028] In one of the first and second heating modes, the first and second tracks may be active, and in the other of the first and second heating modes, the first track may be active and the second track may be inactive. In other words, in one heating mode, a single track may be active, and in the other heating mode, both tracks may be active. This may be preferred when one of the two heating modes requires more heating than the other, or when one of the two heating modes requires more rapid heating than the other. For example, in the second heating mode, both heating tracks may be active, and in the first heating mode, only one heating track may be active (or vice versa).

[0029]

[0029] The device may include a first and a second heater. In this case, in one of the first and second heating modes, the first and second heaters may be active, and in the other of the first and second heating modes, the first heater may be active and the second heater may be inactive. In other words, in one heating mode, only one of the heaters may be active, and in the other heating mode, both heaters may be active. As mentioned above, this may be preferable when one of the two heating modes requires more heating than the other, or when one of the two heating modes requires more rapid heating than the other. For example, in the second heating mode, both heaters may be active, and in the first heating mode, only one heater may be active (or vice versa).

[0030]

[0030] The device may include a first heater configured to operate according to a first heating mode and a second heater configured to operate according to a second heating mode. In this embodiment, the heaters may only operate separately (not simultaneously). The first and second heaters may be configured to heat to different temperatures (e.g., when the same voltage is applied to both heaters). The first and second heaters may be configured to heat at different rates (e.g., when the same voltage is applied to both heaters). The first and second heaters may be different shapes and / or sizes and / or have different arrangements of heater tracks. The first and second heaters may be formed from different materials. One of the first and second heaters may be an internal heater (e.g., inserted into the consumable) and the other of the first and second heaters may be an external heater (e.g., contacts the consumable but is not inserted into the consumable).

[0031]

[0031] The first heater may be configured to directly contact the aerosol-forming substrate of the consumable. The second heater may be configured to contact a heating element of the consumable, such that the second heater can indirectly heat the aerosol-forming substrate of the consumable.

[0032]

[0032] The device may include a consumable detection sensor for detecting a type of consumable engaged with the device. The controller may be configured to control one or more heaters in response to the detected consumable type. For example, the consumable detection sensor may be a switch or button that is activated by one consumable type but not another. Alternatively, the sensor may be an RFID reader or a barcode reader. In this regard, the consumable may be provided with a barcode or RFID tag for reading by the device. The sensor may detect the shape, size, and / or color of the consumable (e.g., by an optical sensor). The controller may switch between a first heating mode and a second heating mode depending on the detected consumable type.

[0033]

[0033] The device may include a user input module configured to receive a selection of a consumable type from a user. The user input module may form part of a user interface (UI) of the device. The controller may be configured to control one or more heaters in response to the selected consumable type. The input module may include, for example, a switch, a button, a touch screen, etc. When the input module includes a touch screen, a selection of two consumable types may be presented to the user, and the user may select the consumable type by touching an appropriate location on the screen. The controller may switch between a first mode and a second mode depending on the consumable type selected by the user.

[0034]

[0034] The user input module may allow the user to control further aspects of the operation of the device. For example, the user input module may include a power button for switching the device between an on and an off state. In some embodiments, the UI may additionally or alternatively include output means for communicating information to the user (i.e., may include a touch screen). The output means may be configured to indicate a current mode of the device (i.e., whether the heater is operating according to a first mode or a second mode). In some embodiments, the output means may also include a light for indicating a status of the device (and / or the aerosol-forming article) to the user. The status of the device (and / or the aerosol-forming article) indicated to the user may include a status indicative of the operation of the at least one heater (i.e., the mode of the at least one heater). The status may also include whether the heater is in an off or on state. The output means may include one or more (e.g., two, three, four, etc.) light-emitting diodes ("LEDs"), which may be located on the body of the device.

[0035]

[0035] The device may include a valve for controlling airflow through the consumable. For example, the device may include an inlet for supplying air to the consumable (i.e., when inhaled by a user). The valve may be located in a passageway connecting the inlet to the consumable. The valve may be configured to modify the airflow through the passageway (e.g., by changing the size of a portion of the passageway). The valve may include an actuator for modifying a position of the valve. The actuator may be controllable by a controller. The controller may cause the actuator to move the valve between a first position and a second position depending on whether the one or more heaters are operating according to a first heating mode or a second heating mode. For example, when the device is in the second mode (i.e., when heating an e-cigarette consumable), a greater airflow may be provided through the consumable. That is, the controller may be configured to move the valve to a first position in the first mode and to a second position in the second mode, and the valve may allow a greater airflow in the second position.

[0036]

[0036] The device may further include a puff sensor (e.g., an airflow sensor). The puff sensor may be configured to detect inhalation by a user through the consumable. The puff sensor may be, for example, a pressure sensor or a microphone. The puff sensor may be configured to generate a signal indicative of a puff state. The signal may indicate that a user has inhaled (aerosol from an aerosol-forming article), for example in the form of a binary signal. Alternatively, or in addition, the signal may indicate a characteristic of the inhalation (e.g., flow rate of the inhalation, length of time of the inhalation, etc.). The second heating mode may include controlling at least one heater in response to detection of inhalation by a user. For example, when in the second heating mode, the controller may activate at least one heater or a particular heating track only when inhalation is detected (or for a period during which inhalation is detected).

[0037]

[0037] In some embodiments, rather than modifying the airflow through the device via a valve, the e-cigarette and non-combustion heating consumables may be configured to allow different airflows to pass. For example, the consumables may include different opening sizes or other means for providing different airflows. In this case, the puff sensor may instead provide a means for detecting which type of consumable is engaged with the device. The puff sensor may detect characteristics of the airflow that may differ between different types of consumables. This information may be provided to the controller, and in response, the controller may switch between the first and second modes.

[0038]

[0038] The first heating mode may include activating at least one heater for a predetermined period of time. The first heating mode may include activating the heater for a predetermined maximum period of time. That is, the controller may be configured to deactivate the heater before the predetermined period of time is completed, for example if the user turns off the device.

[0039]

[0039] The device may include a body supporting the heater and a cap removably engageable with the body. The cap may be configured to receive a consumable such that when engaged with the body, the heater is capable of heating the consumable (e.g., by insertion into or contact with the consumable). The cap may be replaceable with a further (separate) cap. One of the caps may be configured to receive a non-combustion heating consumable and the other may be configured to receive an e-cigarette consumable.

[0040]

[0040] The body of the device may be elongated. An end of the elongated body may be configured to engage a consumable. The terms "heated tobacco" and "non-combustion heated" are used interchangeably herein to describe a type of consumable that is heated rather than combusted (or are used interchangeably to describe a device for use with such a consumable). The device may include a cavity configured to receive (i.e., engage) at least a portion of the consumable.

[0041]

[0041] The at least one heater may include a heating element, which may be in the form of a rod extending from the body of the device. Only one heating element is briefly described below, but as provided above, the device may include multiple heating elements, some or all of which may be as described below.

[0042]

[0042] At least one heater (and thus a heating element) may be rigidly attached to the body. The heating element may be elongated to define a longitudinal axis and may, for example, have a substantially circular transverse profile (i.e. transverse to the longitudinal axis of the heating element) (i.e. the heating element may be generally cylindrical). Alternatively, the heating element may have a rectangular transverse profile (i.e. the heater may be a "blade heater"). Alternatively, the heating element may be shaped like a tube (i.e. the heater may be a "tubular heater"). The heating element may take other shapes (e.g. the heating element may have an oval transverse profile). The shape and / or size (e.g. diameter) of the transverse profile of the heating element may be generally consistent over the entire length (or substantially the entire length) of the heating element.

[0043] The heating element may be 15mm to 25mm long, such as 18mm to 20mm long, such as about 19mm long. The heating element may have a diameter of 1.5mm to 2.5mm, such as a diameter of 2mm to 2.3mm, such as a diameter of about 2.15mm.

[0044]

[0044] The heating element may be formed from a ceramic. The heating element may include a core (e.g., a ceramic core) including Al2O3. The heating element core may have a diameter of 1.8 mm to 2.1 mm, such as 1.9 mm to 2 mm. The heating element may include an outer layer (e.g., an outer ceramic layer) including Al2O3. The outer layer may have a thickness of 160 μm to 220 μm, such as 170 μm to 190 μm, such as about 180 μm. As discussed above, the heating element may include one or more heating tracks, which may extend longitudinally along the heating element. The heating tracks may be sandwiched between the outer layer and the core of the heating element. The heating tracks may include tungsten and / or rhenium. The heating tracks may have a thickness of about 20 μm.

[0045]

[0045] The heating element may be located in a cavity (of the device) and may extend from an interior base of the cavity toward an opening of the cavity (e.g., along a longitudinal axis). The length of the heating element (i.e., the length of the at least one heater along the longitudinal axis) may be less than the depth of the cavity. Thus, the heating element may extend over only a portion of the length of the cavity. That is, the heating element may not extend through (or beyond) the opening of the cavity.

[0046]

[0046] When the at least one heater is configured to be inserted into the consumable, a distal end of the heating element of the at least one heater (i.e., distal from a base of the heating element that is attached to the device) may include a tapered portion to facilitate insertion of the heating element into the consumable. The heating element may fully penetrate the consumable when the consumable is received in the cavity. That is, the entire length or substantially the entire length of the heating element may be received in the consumable.

[0047]

[0047] The heating element may have a length less than or substantially the same as the axial length of the aerosol-forming substrate or aerosol-forming liquid (i.e. or tank) portion of the consumable. Thus, when such a consumable is engaged with the device, the heating element of the at least one heater may penetrate only the aerosol-forming substrate or tank, and not other components of the consumable. The heating element may penetrate the aerosol-forming substrate or tank over substantially the entire axial length of the aerosol-forming substrate or tank of the consumable. Thus, when penetrated by the heating element, heat may be transferred from the heating element (e.g., its outer circumferential surface) to the surrounding aerosol-forming substrate or aerosol-forming liquid. That is, heat may be transferred radially outward (in the case of a cylindrical heating element) or, for example, radially inward (in the case of a tubular heater).

[0048]

[0048] In case the at least one heater is for example an external tubular heater, the heating element of the tubular heater may surround at least a part of the cavity. When a part of the consumable is received in the cavity, the heating element may surround (i.e. heat) a part of the consumable. In particular, the heating element may surround the aerosol-forming substrate or the aerosol-forming liquid (tank) of the consumable. That is, when the consumable is engaged with the device, the aerosol-forming substrate or the tank of the aerosol-forming liquid of the consumable may be located adjacent to an inner surface of the (tubular) heating element. When the heating element is activated, heat may be transferred radially inwards from the inner surface of the heating element to heat the aerosol-forming substrate or the aerosol-forming liquid of the consumable.

[0049]

[0049] The cavity may include a (e.g., circumferential) wall (or walls) and the (tubular) heating element may extend around at least a portion of this wall. In this manner, the wall may be located between an inner surface of the heating element and an outer surface of the consumable. The wall (or walls) of the cavity may be formed from a thermally conductive material (e.g., metal) to allow for heat conduction from the heating element to the consumable. Thus, heat may be conducted from the heating element through the cavity wall (or walls) to an aerosol-forming substrate or aerosol-forming liquid of the consumable received in the cavity.

[0050]

[0050] In some embodiments, the heater may be configured to provide heat to a heating element of the consumable (without directly heating the aerosol-forming substrate or aerosol-forming liquid of the consumable). In such cases, at least one heater may include a heat transfer plate for contacting a corresponding heat transfer plate of the consumable. This heat transfer is suitable, for example, for an e-cigarette system where the consumable includes a tank that contains an aerosol-forming liquid (e.g., e-liquid).

[0051]

[0051] The cap may be disposed on an end of the body configured to engage the aerosol-forming article. The cap may at least partially enclose the at least one heater when engaged with the body. The cap may be movable between an open position, in which access to the heater is provided, and a closed position, in which the cap at least partially encloses the at least one heater. The cap may be slidably engaged with the body of the device and may be slidable between the open and closed positions.

[0052]

[0052] The cap may define at least a portion of the cavity of the device. That is, the cavity may be completely defined by the cap, or the cap and the body may each define a portion of the cavity. If the cap completely defines the cavity, the cap may include an opening for receiving at least one heater into the cavity (when the cap is in the closed position). The cap may include an opening to the cavity. The opening may be configured to receive at least a portion of the consumable. That is, the consumable may be inserted into the cavity (engaged to the device) through the opening. The opening and cavity may be configured to receive both e-cigarette consumables and non-combustion heating consumables.

[0053]

[0053] The cap may be configured such that when the consumable is engaged with the device (e.g., received in the cavity), only a portion of the consumable is received in the cavity. That is, a portion of the consumable (not received in the cavity) may protrude from the opening (i.e., extend beyond the opening). This (protruding) portion of the consumable may be the end (e.g., the mouth end) of the consumable, which may be received in the mouth of a user for the purpose of inhaling an aerosol formed by the device.

[0054]

[0054] The device may include a power source or may be connectable to a power source (e.g., a power source separate from the device). The power source may be electrically connectable to the at least one heater. In that regard, changing (e.g., toggling) the electrical connection of the power source to the at least one heater may affect the state of the at least one heater. For example, toggling the electrical connection of the power source to the at least one heater may toggle the at least one heater between an on state and an off state. The power source may be a power store. For example, the power source may be a battery or a rechargeable battery (e.g., a lithium ion battery).

[0055]

[0055] The device may include an input connection (e.g., a USB port, a Micro USB port, a USB-C port, etc.). The input connection may be configured to connect to an external power source, such as a power outlet. The input connection may in some cases be used as a substitute for an internal power source (e.g., a battery or a rechargeable battery). That is, the input connection may be electrically connectable to a heater (to provide power to the heater). Thus, in some forms, the input connection may form at least a portion of the power source of the device.

[0056]

[0056] If the power source includes a rechargeable power source (such as a rechargeable battery), the input connection may be used to charge and recharge the power source.

[0057]

[0057] The controller may include a microcontroller, which may be mounted, for example, on a printed circuit board (PCB). The controller may also include a memory, for example a non-volatile memory. The memory may include instructions that, when executed, cause the controller to perform certain tasks or steps of a method. If the device includes an input connection, the controller may be connected to the input connection.

[0058]

[0058] The controller may be configured to control the voltage applied by the power supply to the heater. For example, the controller may be configured to toggle between applying the full output voltage (of the power supply) to the heater and applying no voltage to the heater. Alternatively, or in addition, the control unit may implement a more complex heater control protocol (i.e., which may differ depending on the heating mode).

[0059]

[0059] The device may further include a voltage regulator for regulating the output voltage provided by the power supply to form a regulated voltage. The regulated voltage may then be applied to the heater.

[0060]

[0060] As discussed above, if the device includes a UI, the controller may be operatively connected to one or more components of the UI. The controller may be configured to receive command signals from an input means of the UI. The controller may be configured to control the heaters in response to the command signals. For example, in addition to controlling a mode of the at least one heater, the controller may be configured to receive "on" and "off" command signals from the UI and, in response thereto, control the at least one heater to a corresponding on or off state.

[0061]

[0061] The controller may be configured to send output signals to components of the UI. The UI may be configured to communicate information to a user via the output means in response to such output signals (received from the controller). For example, if the device includes one or more LEDs, the LEDs may be operably connected to the controller. The controller may thus be configured to control the illumination of the LEDs (e.g., in response to the output signals). For example, the controller may be configured to control the illumination of the LEDs in accordance with a state (e.g., on or off) of at least one heater and a mode of at least one heater.

[0062]

[0062] If the device includes a sensor (e.g., a puff / airflow sensor), the controller may be operatively connected to the sensor. The controller may be configured to receive a signal from the sensor (e.g., indicative of a state of the device and / or an engaged aerosol-forming article). The controller may be configured to control the heater, or a configuration of the output means, based on the signal from the sensor.

[0063]

[0063] The device may include a wireless interface configured to communicate wirelessly (e.g., via Bluetooth (e.g., a Bluetooth low energy connection) or WiFi) with an external device. Similarly, the input connection may be configured for a wired connection to an external device to provide communication between the device and the external device.

[0064]

[0064] The external device may be a mobile device. For example, the external device may be a smartphone, a tablet, a smart watch, or a smart car. An application (e.g., an app) may be installed on the external device (e.g., a mobile device). The application may facilitate communication between the device and the external device via a wired or wireless connection.

[0065]

[0065] The wireless or wired interface may be configured to communicate signals between an external device and a controller of the device. In this regard, the controller may control the configuration of the device in response to signals received from the external device. Alternatively, or in addition, the external device may respond to signals received from the device (e.g., the controller of the device).

The system may include further consumables. The system may include a non-combustion heating consumable and an e-cigarette consumable.

[0068]

[0068] As used herein, the terms "upstream" and "downstream" are intended to refer to the direction of vapor / aerosol flow, i.e., the downstream end of the article / consumable is the mouth end or outlet where the aerosol exits the consumable for inhalation by the user. The upstream end of the article / consumable is the end opposite the downstream end. Non-combustion heating consumables may include an aerosol-forming substrate.

[0069]

[0069] The aerosol-forming substrate is capable of being heated to release at least one volatile compound capable of forming an aerosol. The aerosol-forming substrate may be located at the upstream end of the article / consumable.

[0074]

[0074] The aerosol-forming substrate of a non-combustion heat-up consumable product may comprise a collecting sheet of homogeneous (eg, paper / slurry recon) tobacco, or a collecting strip / strip formed from such a sheet.

[0075]

[0075] The aerosol-forming substrate of the non-combustion heating consumable product may include one or more additives selected from humectants, flavoring agents, fillers, aqueous / non-aqueous solvents, and binders.

[0076]

[0076] The flavourings may be provided in solid or liquid form. The flavourings may include menthol, licorice, chocolate, fruit flavours (including, for example, citrus, cherry, etc.), vanilla, spices (e.g., ginger, cinnamon), and tobacco flavours. The flavourings may be uniformly dispersed throughout the aerosol-forming substrate or may be provided at discrete locations and / or at varying concentrations throughout the aerosol-forming substrate.

[0077]

[0077] The aerosol-forming substrate of the non-combustion heating consumable product may be formed in a substantially cylindrical shape such that the article / consumable resembles a conventional cigarette. The aerosol-forming substrate may have a diameter of 5-10 mm, such as 6-9 mm or 6-8 mm, for example about 7 mm. The aerosol-forming substrate may have an axial length of 10-15 mm, for example 11-14 mm, such as about 12 or 13 mm.

[0078]

[0078] The non-combustion heated consumable may include at least one filter element. A terminal filter element may be located at the downstream / mouth end of the article / consumable.

[0079]

[0079] The or at least one filter element (e.g., an end filter element) may be constructed from cellulose acetate or polypropylene tow. The at least one filter element (e.g., an end filter element) may be constructed from activated carbon. The at least one filter element (e.g., an end element) may be constructed from paper. The or each filter element may be at least partially (e.g., entirely) circumscribed by a plug wrap, e.g., a paper plug wrap.

[0080]

[0080] A terminal filter element (the downstream end of the article / consumable) can be joined to an upstream element to form the article / consumable by a circumscribing tipping layer, such as a tipping paper layer. The tipping paper can have an axial length greater than the axial length of the terminal filter element, such that the tipping paper completely circumscribing the terminal filter element and the wrap layer surrounding any adjacent upstream elements.

[0081]

[0081] In some embodiments, the non-combustion heated consumable product may include an aerosol cooling element adapted to cool the aerosol generated (by heat exchange) from the aerosol-forming substrate before it is inhaled by the user.

[0082]

[0082] The non-combustion heating consumable may include a spacer element that defines a space or cavity between the aerosol-forming substrate and the downstream end of the consumable. The spacer element may include a paper tube. The spacer element may be circumscribed by a (paper) wrap layer.

[0083]

[0083] The e-cigarette consumable may be configured to be received and retained in the cavity of the device (i.e., engaged with the device). The e-cigarette consumable may be retained by, for example, an interference fit, a threaded fastening, a bayonet fit, or a snap-engagement mechanism.

[0084]

[0084] The e-cigarette consumable may include a tank, which may define a reservoir for storage of an aerosol former. The aerosol former may be in the form of an e-liquid (stored in the reservoir).

[0085]

[0085] E-cigarette consumables may be "disposable" consumables. That is, when the e-liquid in the tank is depleted, the intention may be for the user to dispose of the entire consumable. Alternatively, the e-liquid may be the only part of the system that is truly "disposable". For example, the tank may be refillable with e-liquid, or another component of the system (internal to the device or external to the device, e.g., a refillable cartomizer) may define a reservoir for the e-liquid.

[0086]

[0086] As described above, the e-cigarette consumable may include a heating element configured to receive heat from a heater of the device to heat and vaporize the e-liquid. The e-cigarette consumable may include a porous wick that transfers the e-liquid from the tank to the heating element. The heating element of the e-cigarette consumable may be a heating filament wound (e.g., helically) around at least a portion of the porous wick, such that when the heating element is heated by the heater of the device, heat may be transferred from the heating element to the e-liquid transferred by the wick. This heat transfer may cause the e-liquid to vaporize, and the resulting vapor may be entrained in an airflow passing through the consumable.

[0087]

[0087] As discussed above, the e-cigarette consumable may further include one or more heater connectors that thermally connect a heater of the device to a heating element of the consumable. The heater connectors may be in the form of a thermally conductive element or contact (e.g., a metal plate) and may be located on a surface of the e-cigarette consumable that faces the device in use.

[0088]

[0091]

[0101] Aspects and embodiments of the present invention are discussed below with reference to the accompanying figures. Further aspects and embodiments will be apparent to those skilled in the art. All documents mentioned in this text are incorporated herein by reference.

[0092]

[0102] 1 is a schematic diagram providing a general overview of a smoking substitution system 100. The system 100 includes a substitute smoking device 101 and an aerosol-forming article in the form of a consumable 102, which includes an aerosol former 103. The system is configured to vaporize the aerosol former 103 by heating the aerosol former 103 (forming a vapor / aerosol for inhalation by a user).

[0093]

[0103] The heater 104 forms part of the device 101 and is configured to heat the aerosol formation body 103 of the consumable 102. The heater 104 is electrically connected to a power source 105. Heat from the heater 104 causes the aerosol formation body 103 to evaporate, producing vapour. The vapour then condenses to form an aerosol, which is ultimately inhaled by a user.

[0094]

[0104] The power source 105 may form part of the device 101 or may be located external to the device 101 (but connectable to the device 101). The power source 105 is electrically connected to the heater 104 such that it is able to provide power to the heater 104 (i.e., for heating the aerosol formation body 103). Thus, controlling the electrical connection of the power source 105 to the heater 104 provides control of the state of the heater 104. The power source 105 may be a power store, for example a battery or a rechargeable battery (e.g., a lithium ion battery).

[0095]

[0105] The system 100 further includes an I / O module that includes a connector 106 (e.g., in the form of a USB port, a Micro USB port, a USB-C port, etc.). The connector 106 is configured to connect to an external power source, e.g., a power outlet. The connector 106 may be used as a substitute for the power source 105; that is, the connector 106 may be electrically connectable to the heater 104 to provide electricity to the heater 104. In such an embodiment, the device may not include a power source, and instead the power source of the system may include the connector 106 and the external power source (with the connector 106 providing the electrical connection).

[0096]

[0106] In some embodiments, the connector 106 may be used to charge and recharge the power source 105 if the power source 105 includes a rechargeable battery.

[0097]

[0107] The system 100 also includes a user interface (UI) 107. Although not shown, the UI 107 may include input means for receiving commands from a user. The input means of the UI 107 allows a user to control at least one aspect of the operation of the system 100. The input means may be in the form of, for example, buttons, a touch screen, switches, a microphone, etc.

[0098]

[0108] The UI 107 also includes output means for communicating information to the user, which may include, for example, lights (e.g., LEDs), a display screen, a speaker, a vibration generator, etc.

[0099]

[0109] The system 100 further includes a controller 108 configured to control at least one function of the device 101. In the embodiment shown, the controller 108 is a component of the device 101, but in other embodiments, the controller 108 may be separate from (but connectable to) the device 101. The controller 108 may be configured to control the operation of the heater 104, for example, to control the voltage applied to the heater 104 from the power source 105. The controller 108 may be configured to toggle the supply of power to the heater 104 between an on state, in which the full output voltage of the power source 105 is applied to the heater 104, and an off state, in which no voltage is applied to the heater 104.

[0100]

[0110] Although not shown, the system 100 may also include a voltage regulator for regulating the output voltage from the power supply 105 to form a regulated voltage. The regulated voltage may then be applied to the heater 104.

[0101]

[0111] In addition to being connected to the heater 104, the controller 108 is operatively connected to the UI 107. Thus, the controller 108 can receive input signals from the input means of the UI 107. Similarly, the controller 108 can transmit output signals to the UI 107. In response, the output means of the UI 107 can convey information to a user based on the output signal. The controller 108 also includes a memory, which is a non-volatile memory. The memory includes instructions that, when executed, cause the controller to perform certain tasks or steps of a method.

[0102]

[0112] 2A and 2B show a smoking substitution system 200. The system 200 is an example of the system 100 described in relation to FIG. 1. The illustrated system 200 includes a device 201 and a consumable 202. As described further below, the device 201 is compatible with both non-combustion heating consumables and e-cigarette consumables. In this case, non-combustion heating consumables and e-cigarette consumables of similar shapes may be used with the device 201. The description of FIG. 1 above is also applicable to the system 200 of FIG. 2A and 2B and therefore will not be repeated.

[0103]

[0113] The device 201 and the consumable 202 are configured such that the consumable 202 can be engaged with the device 201. Figure 2A shows the device 201 and the consumable 202 in an engaged state, and Figure 2B shows the device 201 and the consumable 202 in a detached state.

[0104]

[0114] The device 201 includes a body 209 and a cap 210. In use, the cap 210 is engaged at an end of the body 209. Although not apparent from these figures, the cap 210 is movable relative to the body 209. In particular, the cap 210 is slidable and can slide along the longitudinal axis of the body 209. The cap 210 is configured to receive both non-combustion heating consumables and e-cigarette consumables. In other embodiments of the system, different caps may be attached to the device depending on whether the device is used with non-combustion heating consumables or e-cigarette consumables.

[0105]

[0115] The device 201 includes output means (forming part of the UI of the device 201) in the form of a plurality of light emitting diodes (LEDs) 211 arranged linearly on an outer surface of the body 209 of the device 201 along a longitudinal axis of the device 201. A button 212 is also arranged on the outer surface of the body 209 of the device 201 and is spaced axially (i.e. along the longitudinal axis) from the plurality of LEDs 211.

[0106]

[0116] 2C shows a detailed cross-sectional view of an exemplary non-combustion heating consumable 202 of the system 200. The non-combustion heating consumable 202 is generally similar to a cigarette. In that respect, the consumable 202 has a generally cylindrical shape with a diameter of 7 mm and an axial length of 70 mm. The consumable 202 includes an aerosol-forming substrate 213, a terminal filter element 214, an upstream filter element 215, and a spacer element 216. In other embodiments, the consumable can further include a cooling element. The cooling element can exchange heat with the vapor formed by the aerosol-forming substrate 213 to cool the vapor to facilitate condensation of the vapor.

[0107]

[0117] The aerosol-forming substrate 213 is substantially cylindrical, is located at the upstream end 217 of the consumable 202, and comprises the aerosol former of the system 200. At that point, the aerosol-forming substrate 213 is configured to be heated by the device 201 to emit a vapor. The emitted vapor is then entrained in an airflow passing through the aerosol-forming substrate 213. The airflow is created by the action of a user inhaling at the downstream end 218 (i.e., the distal or oral end) of the consumable 202.

[0108]

[0118] In this embodiment, the aerosol-forming substrate 213 includes a tobacco material, which may include, for example, any suitable part of a tobacco plant (e.g., leaves, stems, roots, husks, seeds, and flowers). The tobacco may include one or more of leaf tobacco, stem tobacco, tobacco powder, tobacco dust, tobacco derivatives, expanded tobacco, homogenized tobacco, cut tobacco, extruded tobacco, cut rag tobacco, and / or reconstituted tobacco (e.g., slurry recon or paper recon). For example, the aerosol-forming substrate 213 may include a collecting sheet of homogenous (e.g., paper / slurry recon) tobacco, or collecting strips / strips formed from such a sheet.

[0109]

[0119] To generate an aerosol, the aerosol-forming substrate 213 includes at least one volatile compound that is intended to be evaporated / aerosolized and that, when inhaled, can provide a recreational and / or medicinal effect to the user. The aerosol-forming substrate 213 can further include one or more additives. For example, such additives can be in the form of humectants (e.g., propylene glycol and / or vegetable glycerin), flavorings, fillers, aqueous / non-aqueous solvents, and / or binders.

[0110]

[0120] The terminal filter element 214 is also substantially cylindrical and is located at the downstream end 218 of the consumable 202, downstream of the aerosol-forming substrate 213. The terminal filter element 214 is in the form of a hollow filter element with holes 219 (e.g. for air flow) formed therein. The holes 219 have a diameter of 2 mm. The terminal filter element 214 is formed from a porous (e.g. monoacetate) filter material. As mentioned above, the downstream end 218 of the consumable 202 (i.e. where the terminal filter 214 is located) forms the mouthpiece portion of the consumable 202 into which the user inhales. Airflow is drawn from the upstream end 217, through the components of the consumable 202, and out the downstream end 218. The airflow is driven by the user inhaling at the downstream end 218 (i.e. the mouthpiece portion) of the consumable 202.

[0111]

[0121] The upstream filter element 215 is located axially adjacent to the aerosol-forming substrate 213, between the aerosol-forming substrate 213 and the terminal filter element 214. Like the terminal filter 214, the upstream filter element 215 is in the form of a hollow filter element, with holes 220 extending axially therethrough. In this manner, the upstream filter 215 can act as an airflow restrictor. The upstream filter element 215 is formed from a porous (e.g., monoacetate) filter material. The holes 220 of the upstream filter element 215 have a larger diameter (3 mm) than the terminal filter element 214.

[0112]

[0122] Spacer 216 is in the form of a paper tube and defines a cavity or chamber between upstream filter element 215 and terminal filter element 214. Spacer 216 acts to allow both cooling and mixing of the vapor / aerosol from aerosol-forming substrate 213. The spacer has an outer diameter of 7 mm and an axial length of 14 mm.

[0113]

[0123] Although it is not apparent from these figures, the aerosol-forming substrate 213, the upstream filter 215, and the spacer 216 are circumscribed by a paper wrap layer. The terminal filter 214 is circumscribed by a tip layer, which also circumscribes a portion of the paper wrap layer (to connect the terminal filter 214 to the remaining components of the consumable 202). The upstream filter 215 and the terminal filter 214 are circumscribed by a further wrap layer in the form of a plug wrap.

[0114]

[0124] 2D illustrates an exemplary e-cigarette consumable 202' for use with the device 201. As is evident from this figure, the e-cigarette consumable 202' includes a similar configuration to the non-combustion heating consumable 202 described above. The e-cigarette consumable 202' includes an aerosol former in the form of a tank 213' filled with e-liquid. The tank 213' includes a longitudinally extending passageway 230. The passageway 230 is in fluid communication with an inlet 231 and an outlet 232 of the consumable 202' such that air inhaled by a user at the outlet 232 is drawn from the inlet 231 through the passageway 230 (as indicated by the arrows).

[0115]

[0125] The consumable 202' further includes a recess 233 for receiving the heating element 223 of the device 201 (discussed further below). The recess 233 is lined with a heat transfer element 234 in the form of a metal tube. The heat transfer element 234 is connected to a heating filament (not shown) wrapped around a porous wick 235 and includes an opening (not shown) that allows air to flow from the inlet 231 to the passage 230. The porous wick 235 extends transversely across the passage 230 such that an end of the porous wick 235 is immersed in the e-liquid stored in the tank 213' and a central portion of the wick 235 is exposed to the air flowing through the passage 230. Thus, in operation, heat is transferred from the heating element 223 of the device to the porous wick 235 (via the heat transfer element 234). This causes the e-liquid held in the porous wick 235 to evaporate and become entrained in the air flowing through the passage 230. This air-entrained vapor later cools to form an aerosol, which is inhaled by the user.

[0116]

[0126] Referring again now to the device 201, FIG. 2E shows a detailed view of an end of the device 201 configured to engage a consumable 202 (either in the form of an e-cigarette consumable 202′ or in the form of a non-combustion heating consumable 202). The cap 210 of the device 201 includes an opening 221 to an interior cavity 222 defined by the cap 210 (as is more evident from FIG. 2D). The opening 221 and the cavity 222 are formed to receive at least a portion of the consumable 202. When the consumable 202 is engaged with the device 201, a portion of the consumable 202 is received through the opening 221 and into the cavity 222. After engagement (see FIG. 2B), the downstream end 218 of the consumable 202 protrudes from the opening 221 and thus from the device 201. The opening 221 includes a laterally disposed notch 226. When the consumable 202 is received in the opening 221 , these notches 226 remain open and may be used, for example, to hold a cover to cover the end of the device 201 .

[0117]

[0127] 2F shows a cross-sectional view taken at a central longitudinal plane through the device 201. The device 201 is shown engaged with a consumable 202 (in this case a non-combustion heated consumable 202).

[0118]

[0128] The device 201 includes a heater 204, which includes a heating element 223. The heater 204 forms part of the body 209 of the device 201 and is rigidly attached to the body 209. In the embodiment shown, the heater 204 is a rod heater and the heating element 223 has a circular transverse profile. In other embodiments, the heater may be in the form of a blade heater (e.g., a heating element having a rectangular transverse profile) or a tubular heater (e.g., a heating element having a tubular shape).

[0119]

[0129] The heating element 223 of the heater 204 protrudes from the interior base of the cavity 222 along the longitudinal axis towards the opening 221. As is evident from this view, the length of the heating element (i.e., the length along the longitudinal axis) is less than the depth of the cavity 222. In this manner, the heating element 223 does not protrude from or extend beyond the opening 221.

[0120]

[0130] When the consumable 202 is received in the cavity 222 (as shown in FIG. 2E ), the heating element 223 penetrates the aerosol-forming substrate 213 of the consumable 202. In particular, when inserted, the heating element 223 extends across substantially the entire axial length of the aerosol-forming substrate 213. Thus, when the heater 204 is activated, heat is transferred radially from the outer circumferential surface of the heating element 223 to the aerosol-forming substrate 213.

[0121]

[0131] The device 201 further includes an electronics cavity 224. Located in the electronics cavity 224 is a power source in the form of a rechargeable battery 205 (a lithium ion battery).

[0122]

[0132] The device 201 includes a connector (i.e., forming part of the IO module of the device 201) in the form of a USB port 206. For example, the connector may alternatively be, for example, a micro USB port or a USB-C port. The USB port 206 may be used to recharge the rechargeable battery 205.

[0123]

[0133] The device 201 includes a controller 208 located in the electronics cavity 224. The controller includes a microcontroller mounted on a printed circuit board (PCB). A USB port 206 is also connected to the controller 208 (i.e., connected to the PCB and to the microcontroller).

[0124]

[0134] As described further below, the controller 208 is configured to control at least one function of the device 202. For example, the controller 208 is configured to control the operation of the heater 204 (e.g., in a first and second heating mode). Such control of the operation of the heater 204 may be achieved by the controller toggling an electrical connection of the rechargeable battery 205 to the heater 204. For example, the controller 208 is configured to control the heater 204 in response to a user pressing a button 212. Pressing the button 212 may cause the controller to enable a voltage (from the rechargeable battery 205) to be applied to the heater 204 (heating the heating element 223).

[0125]

[0135] The controller is also configured to control the LEDs 211 in response to a (e.g., detected) state of the device 201 or the consumable 202. For example, the controller may control the LEDs to indicate whether the device 201 is in an on or off state (e.g., one or more of the LEDs may be illuminated by the controller when the device is in an on state).

[0126]

[0136] The device 201 includes a further input means (i.e., in addition to the button 212) in the form of a puff sensor 225. The puff sensor 225 is configured to detect when a user draws (i.e., inhales) on the downstream end 218 of the consumable 202. The puff sensor 225 may be in the form of a pressure sensor, a flow meter, or a microphone, for example. The puff sensor 225 is operatively connected to the controller 208 within the electronics cavity 224 such that a signal from the puff sensor 225 indicative of a puff state (i.e., inhalation or not inhalation) forms an input to (and may therefore be responded to by) the controller 208.

[0127]

[0137] 3 is a schematic diagram illustrating how various components of a device 301 (i.e., device 201, described above, etc.) may be operatively connected. The device 301 includes a controller 308 capable of controlling one or more heaters 323 of the device 301. In particular, the controller 308 is configured to control the heaters 323 according to one of two heating modes. The first heating mode is for heating a non-combustion heated consumable, and the second mode is for heating an e-cigarette consumable. Thus, the device 301 is capable of operating with both types of consumables.

[0128]

[0138] The controller 308 is configured to automatically and manually switch between these two modes. To automatically switch, the controller 308 is connected to a consumable type sensor 340. This sensor 340 is capable of detecting the type of consumable engaged with the device 301 (i.e., e-cigarette or non-combustion heating). The sensor 340 can take multiple forms including, for example, a barcode scanner, an RFID sensor, a light detector, a color detector, a mechanical switch / button. The sensor 340 provides a signal to the controller 308 indicative of the consumable type. The controller switches between the two heating modes based on this signal.

[0129]

[0139] Manual switching may be provided by a user input 341 forming part of the UI 342 of the device 301. The user input 341 may be in the form of a button, a switch or for example a touch screen. In this case, the user can select between two heating modes and a signal indicating the selection is provided from the user input 341 to the controller. This may be used to override an automatic selection made by the controller or may be used in the absence of an automatic selection.

[0130]

[0140] The controller 308 is operatively connected to a display 343 of the device 301 and can therefore control the display 343 to indicate (to a user) the current heating mode. When in the first heating mode, the controller 308 is configured to activate the one or more heaters 323 for a predetermined period of time (e.g., 4 minutes) upon receiving a "start" signal. This "start" signal is received by a user input 341. If at any time during the predetermined period a "stop" signal is received from the user input 341, the controller 308 deactivates the one or more heaters 323.

[0131]

[0141] In a second heating mode, the controller 308 is configured to activate the one or more heaters 323 in response to a signal received from a puff sensor 355 of the device 301. The puff sensor 355 may be in the form of, for example, a pressure sensor or an acoustic sensor, and is configured to detect inhalation by a user (i.e., through a mouthpiece of the device or consumable). In this second mode, the one or more heaters 323 are activated only when inhalation is detected.

[0132]

[0142] The controller 308 is further operatively connected to an airflow valve 345. This valve 345 controls the airflow to the consumables engaged to the device 301. The controller 308 is configured to move this valve 345 to different positions (i.e., to provide different airflow) in the first and second heating modes. In particular, the controller 308 is configured to control the valve 345 to allow a greater airflow in the second heating mode.

[0133]

[0143] As will be appreciated, control of the heater(s) 323 will depend on the nature of the heater(s) 323. For example, if multiple heaters 323 are present, different combinations of heaters 323 may be activated in the first and second heating modes. Additionally, the or each heater 323 may have multiple heating tracks, and different combinations of heating tracks may be activated in the first and second heating modes.

[0134]

[0144] Figures 4A and 4B show a further smoking substitution system 400. The system 300 is an example of the system 100 of Figure 1 and includes a device 401 adapted for e-cigarettes and non-combustion heating consumables. In this example, only the e-cigarette consumables 402 are shown and described. The description of Figure 1 above is also applicable to the system of Figures 4A and 4B and will not be repeated here.

[0135]

[0145] The device 401 and consumable 402 are configured such that the consumable 402 can be engaged to the device 401. Figure 4A shows the device 401 and consumable 402 in an engaged state, and Figure 4B shows the device 401 and consumable 402 in a disengaged state. During engagement, a portion of the consumable 402 is received in a cavity 422 of the device 401. The consumable 402 is held within the device 401 via an interference fit (although in other embodiments the device and consumable may be engaged by a threaded, bayonet fit, or snap-engagement mechanism).

[0136]

[0146] The e-cigarette consumable 402 includes a tank 427. The tank 427 defines a reservoir for storage of an aerosol former, which in this embodiment is in the form of an e-liquid.

[0137]

[0147] In this embodiment, the consumable 402 is a "disposable" consumable; that is, when the e-liquid in the tank 427 is depleted, the intention is for the user to dispose of the entire consumable 402. In other embodiments, the e-liquid (i.e., the aerosol former) may be the only part of the system that is truly "disposable." In such embodiments, the tank may be refillable with e-liquid, or the e-liquid may be stored in a non-consumable component of the system. For example, the e-liquid may be stored in a tank located within the device, or may be stored in another component that is itself not disposable (e.g., a refillable cartomizer).

[0138]

[0148] In the illustrated system 400, a heat transfer element is located within the consumable 402 and configured to heat and vaporize the e-liquid (stored in the tank 427). Although not shown, the heat transfer element provides heat to a porous wick via a resistive heating element. The porous wick transfers the e-liquid from the tank 427 to the heating element. The heating element is a heating filament that is spirally wound around a portion of the porous wick, so that when the heating element is heated, heat is transferred from the heating element to the e-liquid transferred by the wick. This heat transfer causes the e-liquid to evaporate, and the resulting vapor is entrained in the airflow passing through the consumable 402 (i.e., driven by the user inhaling at the downstream end 418 of the consumable 402). Between the evaporation point of the coil and the downstream end 418 (i.e., the mouth end), the vapor condenses into an aerosol that is then inhaled by the user.

[0139]

[0149] As with the previously described embodiments, device 401 includes a power source in the form of a rechargeable battery (not shown) and a connector in the form of a USB port (not shown). Device 401 further includes a controller (also not shown). The rechargeable battery, connector, and controller are similar to (and operate similarly to) the corresponding components of the embodiments described above with respect to Figures 2A-2F and 3.

[0140]

[0150] The consumable 402 includes a pair of heat transfer contacts 428 disposed on an end surface of the consumable 402 facing the device. The heat transfer contacts 428 form part of a heat transfer element such that heat received from a heater of the device 401 (when the consumable is engaged with the device) is transferred via the heat transfer contacts 428 to the heat transfer element.

[0141]

[0151] The device 401 includes output means in the form of a single light emitting diode ("LED") 411 (which forms part of the UI of the system 400). The LED 411 is operatively connected to the controller such that the controller can control the illumination of the LED 411. The controller is then configured to illuminate the LED when the heater 404 is activated.

[0142]

[0152] The device 401 also includes input means in the form of a puff sensor (not shown), which is the same as that described above with respect to the embodiment of Figures 2A-2F and 3.
