Description

Technical Field

[0001] The present invention relates to smoking substitute systems and particularly, but not exclusively, to smoking substitute systems comprising heat not burn devices and methods of operating such devices in different operating modes. Background Art

[0002] Smoking tobacco is generally considered to expose the smoker to potentially harmful substances. It is generally believed that a large number of potentially harmful substances are produced by the burning of tobacco and / or the heat caused by the combustion of the tobacco and the components of the burned tobacco in the tobacco smoke itself.

[0003] Traditional combustible smoking articles, such as cigarettes, typically include a cylindrical tobacco rod consisting of tobacco shreds wrapped by a wrapper, and generally also include a cylindrical filter axially aligned in abutment with the wrapped tobacco rod. The filter generally includes a filter material surrounded by a plug wrap. The wrapped tobacco rod and the filter are connected together by a plugging paper band wrapped around the entire length of the filter and the adjacent portion of the wrapped tobacco rod. This type of traditional cigarette is used by lighting the end opposite to the filter and burning the tobacco rod. The smoker receives mainstream smoke into their mouth by inhaling at the mouth end or filter end of the cigarette.

[0004] It is known that the combustion of organic materials such as tobacco produces tar and other potentially harmful by-products. In order to avoid smoking tobacco, various smoking replacement systems (or "alternative smoking systems") have been proposed.

[0005] Such a smoking replacement system may form part of a nicotine replacement therapy for people wishing to stop smoking and overcome dependence on nicotine.

[0006] Smoking replacement systems include electronic systems that allow users to simulate the act of smoking by generating an aerosol (also called "vapor") that is drawn (inhaled) into the lungs through the mouth and then exhaled. The inhaled aerosol typically carries nicotine and / or flavorings without or with less odor and health risks associated with traditional smoking.

[0007] Typically, smoking alternative systems are intended to provide an alternative to the smoking habit while providing the user with an experience and satisfaction similar to that of traditional smoking and combustible tobacco products. Some smoking alternative systems use smoking alternative articles (also referred to as "consumables") that are designed to resemble traditional cigarettes and are in the form of a cylinder with a nozzle at one end.

[0008] The popularity and use of smoking replacement systems has grown rapidly over the past few years. Although initially marketed as an aid to help habitual smokers who wish to quit smoking, consumers increasingly view smoking replacement systems as an adjunct to a desired lifestyle.

[0009] There are many different kinds of smoking replacement systems, each using a different method of replacing smoking.

[0010] One method used in smoking replacement systems is the so-called heated tobacco ("HT") method, in which tobacco (rather than "e-liquid") is heated or warmed to release vapor. HT is also called "heat not burn" ("HNB"). The tobacco can be tobacco leaf or reconstituted tobacco. The vapor can contain nicotine and / or flavorings. In the HT method, the purpose is that the tobacco is heated but not burned, that is, the tobacco does not undergo combustion.

[0011] Typical HT smoking alternative system can comprise device and consumables.Consumables can comprise tobacco material.Device and consumables can be configured to be physically connected together.In use, heat can be transferred to tobacco material by the heating element of device, wherein the air flow through tobacco material makes the component in tobacco material be released as steam.Steam can also be formed by the carrier (this carrier can for example comprise propylene glycol and / or vegetable glycerine) in tobacco material and other volatile compounds released from tobacco.The steam released can be entrained in the air flow of suction through tobacco.

[0012] As the vapor passes through the consumable (entrained in the air flow) from the vaporization site to the outlet (eg, nozzle) of the consumable, the vapor cools and condenses to form an aerosol that the user breathes in. The aerosol will typically contain volatile compounds.

[0013] In HT smoking replacement systems, heating rather than burning tobacco materials is believed to result in less or less harmful compounds that are typically produced during smoking. Therefore, the HT method can reduce the odor and / or health risks that may be produced by burning, combustion and pyrolytic degradation of tobacco.

[0014] Currently available HT smoking substitute devices are usually shipped in a standby operating mode. In other words, HT smoking substitute devices may be provided with sufficient energy stored in an onboard battery so that they can be used once the user takes them out of their packaging. However, they may be accidentally activated during storage or transportation, thereby creating a safety hazard.

[0015] Improved designs of smoking substitute systems, particularly HT smoking substitute systems, may be needed to enhance the user experience and improve the functionality of HT smoking substitute systems.

[0016] In view of the above considerations, the present disclosure has been designed. Summary of the invention

[0017] In the most general case, the present invention relates to a heat not burn device configured to switch from a locked operating mode to an unlocked operating mode based on detecting the occurrence of a predetermined event or upon receiving a predetermined user input.

[0018] According to a first aspect of the present invention, a heat-not-burn device is provided, which is configured to switch from a locked operating mode to an unlocked operating mode based on detecting the occurrence of a predetermined event and / or after receiving a predetermined user input, wherein the heater of the heat-not-burn device is configured to be disabled during the locked operating mode and enabled during the unlocked operating mode.

[0019] By providing a heat not burn device in which the heater of the device remains disabled or deactivated in a lockout mode, accidental or inappropriate activation of the device can be avoided during storage and / or transportation of the device. A more versatile device is provided that intelligently keeps the heater of the device disabled when transporting and / or storing. Thus, even if the on button is inadvertently pressed during the lockout mode and / or when transporting the device, the device will not activate the heater.

[0020] In the locked operating mode, the device as a whole may not be disabled. In other words, when in the locked operating mode, the heater may be disabled, but the device may remain operational, for example, the controller and user interface of the device may remain operational. More specifically, in the locked operating mode, the battery of the device may not energize the heater via the controller.

[0021] Optional features will now be described. These may be applied alone or in any combination with any aspect.

[0022] Optionally, the device may include a controller configured to switch the device from a locked operating mode to an unlocked operating mode and enable the heater in the unlocked operating mode. For example, in the unlocked operating mode, the heater of the device may not be powered, and additional user input may be required to activate the heater of the device.

[0023] Optionally, the predetermined user input includes a predetermined sequence of user presses at a user interface of the device. The user interface may be a button, or may be other user interfaces, such as a switch and a touch-sensitive screen. The predetermined sequence of user presses may minimize the chance that the device switches from a locked operating mode to an unlocked operating mode due to random button presses during transportation / packaging of the device. For example, the predetermined sequence of user presses may be configured in a manner such that random presses on the user interface may not match the predetermined sequence of user presses. Thus, the device may intelligently prevent unintentional activation of the device during storage and / or transportation. For example, the predetermined sequence of user presses or button presses may be any of the following: (i) pressing a button a predetermined number of times, such as 5 times; (ii) pressing and holding a button within a predetermined time period, such as 3 seconds, or (iii) pressing a button a predetermined number of times, wherein during each button press, the button is held pressed within a predetermined time period.

[0024] Optionally, the predetermined user input comprises a predetermined movement of the device, wherein the device further comprises a motion sensor for detecting the predetermined movement. The motion sensor may be configured to sense movement or vibration of the device, whereby the controller may be configured to identify a pattern of the sensed movement and compare it with the predetermined movement. After the identified pattern of the sensed movement matches the predetermined movement, the controller may switch the device from the locked operating mode to the unlocked operating mode. The predetermined movement comprises, for example, one or more of a swirling movement, a waving movement or a swinging movement, and a movement in the longitudinal direction.

[0025] Optionally, the heater is configured to be activated in the unlocked operating mode after receiving a further user input at the device, and wherein the predetermined user input is different from the further user input. This may provide additional security to avoid unwanted activation of the heater. For example, even if the device is accidentally switched from the locked operating mode to the unlocked operating mode, the heater of the device may remain deactivated unless a further user input is entered at the device (e.g., at a user interface). The predetermined user input and the further user input may be entered at the same user interface, or they may be entered at different user interfaces.

[0026] Optionally, the predetermined event includes one or more of: i) establishing an electrical connection between the device and an external device, ii) relative movement between the cap of the device and the body of the device (e.g., wherein the cap of the device is lifted away from the device), and iii) engagement of a consumable with the device. This can provide the benefit of switching the device from a locked operating mode to an unlocked operating mode only by user intervention. In other words, none of these events will occur without physical user intervention during storage and / or transportation of the device, thereby further preventing the device from being accidentally activated.

[0027] For example, the relative movement comprises moving or lifting the cap away from the body of the device. Such movement may be detected by a micro switch or trigger disposed between the cap and the body of the device. For example, establishing the electrical connection comprises connecting the device to an external device such as a computing device or a power source. Advantageously, both of these predetermined events may indicate that a user has initiated use of the device, and thus upon detecting lifting of the cap and connection of the device to an external device or power source, the controller may switch the device from a locked operating mode to an unlocked operating mode.

[0028] For example, in some embodiments, the consumables may be packaged separately from the device during storage and transportation, so that when the device detects that the consumables are engaged with the device, such as when the consumables are inserted into a cavity of the device, the controller can determine the user's initial use of the device, and the controller can therefore switch the device from a locked operating mode to an unlocked operating mode.

[0029] Optionally, the device is configured to switch from the unlocked operating mode to the locked operating mode upon receipt of a second predetermined user input, the second predetermined user input being a second predetermined sequence of user presses at a user interface of the device, wherein the second predetermined user input is different from the predetermined user input. Advantageously, this may allow the user to re-initiate the locked operating mode, thereby preventing accidental activation of the heater. This may be particularly advantageous when the device is being transported, for example during daily transfers or when travelling on an aircraft.

[0030] The device may include an elongated body. The end of the elongated body may be configured to engage with an aerosol-forming article. For example, the body may be configured to engage with a heated tobacco (HT) consumable (or a heat-not-burn (HNB) consumable). The terms "heated tobacco" and "heat-not-burn" are used interchangeably herein to describe consumables of the heating-not-burning type (or interchangeably to describe a device used with such consumables). The device may include a cavity configured to accommodate at least a portion of the consumable (i.e., for engaging with the consumable). The aerosol-forming article may be a type that includes an aerosol precursor (e.g., carried by an aerosol-forming substrate).

[0031] The device may include a heater for heating the aerosol-forming article. The heater may include a heating element, which may be in the form of a rod extending from the body of the device. The heating element may extend from the end of the body configured to engage with the aerosol-forming article. In an embodiment, the heater of the device is configured to be disabled in the locked mode and enabled in the unlocked mode. Although the heater of the device is enabled in the unlocked operating mode, the heater of the device will still require additional user input to start.

[0032] The heater (and therefore the heating element) may be securely mounted to the body. The heating element may be elongated so as to define a longitudinal axis, and may, for example, have a substantially circular transverse profile (i.e. perpendicular to the longitudinal axis of the heating element) (i.e. the heating element may be substantially 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 in the shape of a tube (i.e. the heater may be a "tubular heater"). The heating element may take other forms (e.g., the heating element may have an elliptical transverse profile). The shape and / or size (e.g., diameter) of the transverse profile of the heating element may be substantially uniform over the entire length (or substantially the entire length) of the heating element.

[0033] The heating element may be 15 mm to 25 mm long, such as 18 mm to 20 mm long, such as about 19 mm long. The heating element may have a diameter of 1.5 mm to 2.5 mm, such as 2 mm to 2.3 mm in diameter, such as about 2.15 mm in diameter.

[0034] The heating element may be formed of ceramic. The heating element may include a core (e.g., a ceramic core) comprising Al2O3. The diameter of the core of the heating element may be 1.8 mm to 2.1 mm, for example 1.9 mm to 2 mm. The heating element may include an outer layer (e.g., an outer ceramic layer) comprising Al2O3. The thickness of the outer layer may be 160 μm to 220 μm, for example 170 μm to 190 μm, for example about 180 μm. The heating element may include a heating track that may extend longitudinally along the heating element. The heating track may be sandwiched between the outer layer and the core of the heating element. The heating track may contain tungsten and / or rhenium. The heating track may have a thickness of about 20 μm.

[0035] The heating element may be located in the cavity (of the device) and may extend from the interior base of the cavity toward the opening of the cavity (e.g., along the longitudinal axis). The length of the heating element (i.e., along the longitudinal axis of the heater) may be less than the depth of the cavity. Thus, the heating element may extend within only a portion of the length of the cavity. In other words, the heating element may not extend through (or beyond) the opening of the cavity.

[0036] The heating element may be configured to be inserted into an aerosol-forming article (e.g., a HT consumable) when the aerosol-forming article is contained in the cavity. In this regard, the distal end of the heating element (i.e., away from the base of the heating element mounted to the device) may include a tapered portion, which may facilitate insertion of the heating element into the aerosol-forming article. When the aerosol-forming article is contained in the cavity, the heating element may completely penetrate the aerosol-forming article. In other words, the entire length or substantially the entire length of the heating element may be contained in the aerosol-forming article.

[0037] The length of the heating element may be less than or substantially equal to the axial length of an aerosol-forming substrate that forms part of an aerosol-forming article (e.g., an HT consumable). Thus, when such an aerosol-forming article is engaged with the device, the heating element may only penetrate the aerosol-forming substrate, rather than other components of the aerosol-forming article. The heating element may penetrate the aerosol-forming substrate over substantially the entire axial length of the aerosol-forming substrate of the aerosol-forming article. Thus, when penetrated by the heating element, heat may be transferred from the heating element (e.g., the peripheral surface of the heating element) to the surrounding aerosol-forming substrate. In other words, 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).

[0038] In the case where the heater is a tubular heater, the heating element of the tubular heater may surround at least a portion of the cavity. When a portion of the aerosol-forming article is accommodated in the cavity, the heating element may surround that portion of the aerosol-forming article (i.e. so as to heat that portion of the aerosol-forming article). In particular, the heating element may surround an aerosol-forming substrate of the aerosol-forming article. In other words, when the aerosol-forming article is engaged with the device, the aerosol-forming substrate of the aerosol-forming article may be positioned adjacent to the 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.

[0039] The cavity may comprise a (e.g. circumferential) wall (or walls), and the (tubular) heating element may extend around at least a portion of the wall. In this way, the wall may be located between the inner surface of the heating element and the outer surface of the aerosol-forming article. The wall (or walls) of the cavity may be formed of a thermally conductive material (e.g. metal) to allow heat conduction from the heating element to the aerosol-forming article. Thus, heat may be conducted from the heating element through the cavity wall (or walls) to the aerosol-forming substrate of the aerosol-forming article contained in the cavity.

[0040] In some embodiments, the device may include a cap disposed at an end of the body, the cap being configured to engage with the aerosol-forming article. Where the device includes a heater having a heating element, the cap may at least partially enclose the heating element. The cap may be movable between an open position in which access to the heating element is provided and a closed position in which the cap at least partially encloses the heating element. The cap may be slidably engaged with the body of the device and may slide between an open position and a closed position.

[0041] The cap may define at least a portion of a cavity of the device. In other words, the cavity may be completely defined by the cap, or the cap and the body may each define a portion of the cavity. In the case where the cap completely defines the cavity, the cap may include a hole for accommodating a heating element in the cavity (when the cap is in a closed position). The cap may include an opening leading to the cavity. The opening may be configured to accommodate at least a portion of an aerosol-forming article. In other words, the aerosol-forming article may be inserted through the opening and into the cavity (so as to engage with the device).

[0042] The cap may be configured such that when the aerosol-forming article is engaged with the device (e.g. contained in the cavity), only a portion of the aerosol-forming article is contained in the cavity. In other words, a portion of the aerosol-forming article (not contained in the cavity) may protrude from the opening (i.e. extend beyond the opening). This (protruding) portion of the aerosol-forming article may be the terminal (e.g. mouth) end of the aerosol-forming article, which may be contained in the mouth of a user for the purpose of inhaling an aerosol formed by the device.

[0043] The device may include a power source or may be connected to a power source (e.g., a power source separate from the device). The power source may be electrically connected to the heater. In this regard, changing (e.g., switching) the electrical connection between the power source and the heater may affect the state of the heater. For example, switching the electrical connection between the power source and the heater may switch the heater between an on state and an off state. The power source may be a power storage device. For example, the power source may be a battery or a rechargeable battery (e.g., a lithium-ion battery).

[0044] 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. In some cases, the input connection may be used as a substitute for an internal power source (e.g., a battery or rechargeable battery). In other words, the input connection may be electrically connected to the heater (for providing power to the heater). Thus, in some forms, the input connection may form at least part of the power supply for the device.

[0045] Where the power source comprises a rechargeable power source (eg, a rechargeable battery), the input connection may be used to charge and recharge the power source.

[0046] The device may include a user interface (UI). In some embodiments, the UI may include an input mechanism for receiving operating commands from a user. The input mechanism of the UI may allow a user to control at least one aspect of the operation of the device. In some embodiments, the input mechanism may include a power button to switch the device between an on state and an off state. In an embodiment, the input mechanism of the UI may be configured to receive user input to switch the device from a locked operating mode to an unlocked operating mode. In one aspect, the user input for switching the device from a locked operating mode to an unlocked operating mode may be a predetermined sequence of button presses. In an example, the input mechanism may also include a touch screen input, etc.

[0047] In some embodiments, the UI may additionally or alternatively include an output mechanism to convey information to the user. In some embodiments, the output mechanism may be configured to indicate the current operating mode of the device to the user. For example, the output mechanism may be one of a tactile feedback mechanism, an audio feedback mechanism, and a visual feedback mechanism, configured to indicate to the user that the device is switched from a locked mode to an unlocked mode based on the detection of the occurrence of a predetermined event or after receiving a predetermined user input. In some embodiments, the output mechanism may include a light to indicate the status of the device (and / or aerosol-forming product) to the user. The status of the device (and / or aerosol-forming product) indicated to the user may include an indication of the working status of the heater. For example, the status may include whether the heater is in an off state or an on state. In some embodiments, the UI unit may include at least one of a button, a display, a touch screen, a switch, a light, etc. For example, the output mechanism may include one or more (e.g., two, three, four, etc.) light emitting diodes ("LEDs") that may be located on the body of the device.

[0048] The device may also include a suction sensor (e.g., an airflow sensor) that forms part of the input mechanism of the UI. The suction sensor may be configured to detect the end (i.e., the terminal (mouth) end) at which the user inhales the aerosol-forming article. The suction sensor may, for example, be a pressure sensor or a microphone. The suction sensor may be configured to generate a signal indicating a suction state. The signal may indicate that the user inhales (the aerosol from the aerosol-forming article), such that it is, for example, in the form of a binary signal. Alternatively or additionally, the signal may indicate the characteristics of the suction (e.g., the flow rate of the suction, the length of time of the suction, etc.).

[0049] The device may include a controller, or may be connected to a controller, which may be configured to control at least one function of the device. The controller may include, for example, a microcontroller that may be mounted on a printed circuit board (PCB). The controller may also include a memory, such as a non-volatile memory. The memory may include instructions that, when implemented, may cause the controller to perform certain tasks or steps of the method. In the case where the device includes an input connection, the controller may be connected to the input connection.

[0050] The controller is connected to the heater and is configured to control the operation of the heater (and, for example, a heating element). In some embodiments, the controller may be configured to switch the device from a locked operating mode to an unlocked operating mode, and enable the heater in the unlocked operating mode in response to receiving additional user input. The controller may be configured to control the vaporization of the aerosol-forming portion of the aerosol-forming article engaged with the device. The controller may be configured to control the voltage applied to the heater by the power supply. For example, the controller may be configured to switch between applying the full output voltage (of the power supply) to the heater and not applying a voltage to the heater. Alternatively or additionally, the control unit may implement a more complex heater control protocol.

[0051] The device may also include a voltage regulator to adjust the output voltage supplied by the power supply to form a regulated voltage. The regulated voltage may then be applied to the heater. In some embodiments, the voltage regulator may be used to control the voltage supply to the heater in a locked operating mode and an unlocked operating mode. For example, in the locked operating mode, the heater is not provided with any voltage, and in the unlocked mode, the heater is configured to receive a voltage from the power supply.

[0052] In some embodiments where the device includes a UI, the controller may be operably connected to one or more components of the UI. The controller may be configured to receive a command signal from an input mechanism of the UI. The controller may be configured to control the heater in response to the command signal. For example, the controller may be configured to receive "on" and "off" command signals from the UI, and in response, the heater may be controlled so as to be in a corresponding on or off state. In addition, the controller may be configured to receive a command for switching the device from a locked operating mode to an unlocked operating mode via a user input mechanism, and in response, indicate through an output mechanism that the unlocked operating mode is disabled based on the detection of the occurrence of a predetermined event or after receiving a predetermined user input.

[0053] The controller may be configured to send an output signal to a component of the UI. The UI may be configured to communicate information to the user via an output mechanism in response to such an output signal (received from the controller). For example, in the case where the device includes one or more LEDs, the LED may be operably connected to the controller. Therefore, the controller may be configured to control the illumination of the LED (e.g., in response to the output signal). For example, the controller may be configured to control the illumination of the LED according to the (e.g., on or off) state of the heater. In another example, the controller may be configured to control the illumination of an LED indicating that the device has been switched to an unlocked operating mode. In addition, the controller may be configured to indicate that the device has switched from a locked operating mode to an unlocked operating mode through other output mechanisms (e.g., a tactile sensor and an audio sensor, etc.).

[0054] Where the device comprises a sensor (e.g. a puff / airflow sensor), the controller may be operably connected to the sensor. The controller may be configured to receive a signal from the sensor (e.g. indicating a state of the device and / or an engaged aerosol-forming article). The controller may be configured to control an aspect of the heater or output mechanism based on the signal from the sensor.

[0055] The device may include a wireless interface configured to communicate wirelessly with an external device (e.g., via Bluetooth (e.g., Bluetooth low energy connection) or Wi-Fi). Similarly, the input connection may be configured as a wired connection with an external device to provide communication between the device and the external device.

[0056] The external device may be a mobile device. For example, the external device may be a smart phone, 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 connection or a wireless connection.

[0057] The wireless interface or wired interface can be configured to transmit signals between the external device and the controller of the device. At this point, the controller can control an aspect of the device in response to a signal received from the external device. Alternatively or additionally, the external device can respond to a signal received from the device (e.g., from the controller of the device).

[0058] In a second aspect, a system (e.g., a smoking replacement system) is provided, comprising a device according to the first aspect and an aerosol-forming article. The aerosol-forming article may comprise an aerosol-forming substrate at an upstream end of the aerosol-forming article. The article may be in the form of a smoking replacement article, such as a heated tobacco (HT) consumable (also known as a heat-not-burn (HNB) consumable).

[0059] As used herein, the terms "upstream" and "downstream" are intended to refer to the direction of flow of the vapor / aerosol, i.e. the downstream end of the article / consumable is the mouth end or outlet where the aerosol leaves the consumable for inhalation by the user. The upstream end of the article / consumable is the end opposite the downstream end.

[0060] The aerosol-forming substrate is capable of being heated to release at least one volatile compound that can form an aerosol.The aerosol-forming substrate may be located at the upstream end of the article / consumable product.

[0061] In order to generate an aerosol, the aerosol-forming substrate comprises at least one volatile compound which is intended to be vaporized / aerosolized and which, when inhaled, can provide a recreational and / or medical effect to the user. Suitable chemically and / or physiologically active volatile compounds include: nicotine, cocaine for medical effect, caffeine, opium and opioids for medical effect, theophylline and cathinones, kavalactones, mysticin, β-carboline alkaloids, salvinorin A, and any combination and / or synthetic substitutes functionally equivalent to the foregoing.

[0064] The tobacco may include one or more of tobacco leaves, tobacco stems, tobacco powder, tobacco dust, tobacco derivatives, expanded tobacco, homogenized tobacco, shredded tobacco, extruded tobacco, cut tobacco and / or reconstituted tobacco (eg, pulp-based or paper-based).

[0065] The aerosol-forming substrate may comprise collected homogenised (eg paper / pulp reconstituted) tobacco sheets or collected shreds / rods formed from such sheets.

[0066] The aerosol-forming substrate may comprise one or more additives selected from humectants, flavourings, fillers, aqueous / non-aqueous solvents and binders.

It may include menthol, liquorice, chocolate, fruit flavors (including, for example, citrus, cherry, etc.), vanilla, spices (e.g., ginger, cinnamon), and tobacco flavors. The flavoring agent may be uniformly dispersed throughout the aerosol-forming substrate, or may be provided in separate locations and / or varying concentrations throughout the aerosol-forming substrate.

[0068] The aerosol-forming substrate may be formed substantially cylindrically so that the article / consumable resembles a conventional cigarette. Its diameter may be from 5 mm to 10 mm, for example from 6 mm to 9 mm or from 6 mm to 8 mm, for example about 7 mm.

[0094] Aspects and embodiments of the present invention will now be discussed with reference to the accompanying drawings. Other aspects and embodiments will be apparent to those skilled in the art. All documents mentioned herein are incorporated herein by reference.

[0095] Figure 1A is a schematic diagram providing a general overview of a smoking replacement system 100. The system 100 comprises an alternative smoking device 101 and an aerosol-forming article in the form of a consumable 102, the consumable 102 comprising an aerosol precursor 103. The system is configured to vaporize the aerosol precursor 103 by heating the aerosol precursor 103 (so as to form a vapor / aerosol for inhalation by a user).

[0096] In the illustrated system, the heater 104 forms part of the consumable 102 and is configured to heat the aerosol precursor 103. In this variation, for example, when the consumable 102 is engaged with the device 101, the heater 104 may be electrically connected to a power source. The heat from the heater 104 vaporizes the aerosol precursor 103 to produce steam. The steam then condenses to form an aerosol, which is ultimately inhaled by the user. In some embodiments, the heater 104 is configured to be disabled in the locked operating mode and remain enabled in the unlocked operating mode.

[0097] The system 100 also includes a power source 105 that forms part of the device 101. In other embodiments, the power source 105 may be external to the device 101 (but connectable to the device 101). The power source 105 may be electrically connected to the heater 104 so that the power source 105 can supply power to the heater 104 (i.e., for the purpose of heating the aerosol precursor 103). Thus, control of the electrical connection of the power source 105 to the heater 104 provides control over the state of the heater 104. The power source 105 may be a power storage device, such as a battery or a rechargeable battery (e.g., a lithium-ion battery).

[0098] 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, such as a power outlet. The connector 106 can be used in place of the power source 105. In other words, the connector 106 can be electrically connected to the heater 104 to provide power to the heater 104. In such embodiments, the device may not include a power source, and the power source of the system may instead include the connector 106 and the external power source (the connector 106 provides an electrical connection to the external power source).

[0099] In some embodiments, where the power source 105 includes a rechargeable battery, the connector 106 can be used to charge and recharge the power source 105 .

[0100] The system 100 also includes a user interface (UI) 107. Although not shown, the UI 107 may include an input mechanism for receiving commands from a user. The input mechanism of the UI 107 allows the user to control at least one aspect of the operation of the system 100. The input mechanism may be, for example, in the form of a button, a touch screen, a switch, a microphone, etc.

[0101] UI 107 also includes an output mechanism for conveying information to the user. The output mechanism may, for example, include a light (eg, an LED), a display screen, a speaker, a vibration generator, and the like.

[0102] The system 100 also includes a controller 108 and a memory 109 operably connected to the controller 108, the controller 108 being configured to control at least one function of the device 101. In the illustrated embodiment, the controller 108 is a component of the device 101, but in other embodiments, the controller 108 can be separated from the device 101 (but can be connected to the device 101). The controller 108 is configured to switch the device from the locked operating mode to the unlocked operating mode based on the occurrence of a predetermined event detected or after receiving a predetermined user input. The controller 108 is configured to control the operation of the heater 104, for example, the controller can be configured to disable the heater 104 in the locked operating mode and enable the heater 104 in the unlocked operating mode. The controller 108 can also be configured to control the operation of the heater 104, for example, it can be configured to control the voltage applied to the heater 104 from the power supply 105. The controller 108 can be configured to switch the power supply to the heater 104 between an on state (in which the full output voltage of the power supply 105 is applied to the heater 104) and an off state (in which no voltage is applied to the heater 104). In addition, in an example, the controller 108 can be configured to provide power to the heater 104 in the unlocked mode after receiving additional user input, and conversely, the controller 108 is configured not to provide power to the heater 104 in the locked mode.

[0103] Although not shown, the system 100 also includes a voltage regulator that regulates the output voltage from the power supply 105 to form a regulated voltage. The regulated voltage can then be applied to the heater 104.

[0104] In addition to being connected to the heater 104, the controller 108 is operably connected to the UI 107. Thus, the controller 108 can receive input signals from the input mechanism of the UI 107. Similarly, the controller 108 can transmit output signals to the UI 107. In response, the output mechanism of the UI 107 can convey information to the user based on the output signal. The controller also includes a memory 109 as a non-volatile memory. The memory 109 includes instructions that, when implemented, cause the controller to perform certain tasks or steps of the method.

[0105] In addition, the system may further include a sensor 110 coupled to the controller 108 within the heat-not-burn device 101. The sensor 110 may be a motion sensor (not shown) mounted inside the device and configured to generate an input in response to detection of movement of the device 101. The controller 108 is configured to switch the device 101 from a locked operating mode to an unlocked operating mode in response to receiving the input from the sensor 110.

[0106] Figure 1B It is shown Figure 1ASchematic diagram of a variation of the smoking replacement system 100. Figure 1B In the system 100 ′ of , the heater 104 forms part of the device 101 rather than part of the consumable 102 . In this variation, the heater 104 may be electrically connected to the power source 105 .

[0107] Figure 2A and Figure 2B A heated tobacco (HT) smoking alternative system 200 is shown. The system 200 is about Figure 1A or Figure 1B The system 200 includes a HT device 201 and a HT consumable 202, wherein the HT device 201 is configured to switch from a locked operating mode to an unlocked operating mode upon detecting the occurrence of a predetermined event and / or upon receiving a predetermined user input. Figure 1A and Figure 1B Description applies to Figure 2A and Figure 2B system 200 and therefore will not be repeated.

[0108] The device 201 and the consumable 202 are configured such that the consumable 202 can be engaged with the device 201 . Figure 2A The device 201 and consumable 202 are shown in an engaged state, and Figure 2B The device 201 and consumable 202 are shown in a disengaged state.

[0109] The device 201 comprises a body 209 and a cap 210. In use, the cap 210 is engaged at the end of the body 209. Although not apparent in the drawings, 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.

[0110] The device 201 includes an output mechanism (forming part of the UI of the device 201) in the form of a plurality of light emitting diodes (LEDs) 211 arranged linearly along the longitudinal axis of the device 201 and on an outer surface of a body 209 of the device 201. A button 212 is also arranged on the outer surface of the body 209 of the device 201 and is axially spaced from the plurality of LEDs 211 (i.e., along the longitudinal axis).

[0111] Figure 2CShown is a detailed cross-sectional view of the consumables 202 of system 200. The consumables 202 are generally similar to cigarettes. In this regard, the consumables 202 have a diameter of 7mm and an axial length of 70mm in a roughly cylindrical shape. The consumables 202 include an aerosol-forming substrate 213, a terminal filter element 214, an upstream filter element 215, and a spacing element 216. In other embodiments, the consumables may also include a cooling element. The cooling element may exchange heat with the steam formed by the aerosol-forming substrate 213 to cool the steam, thereby promoting the condensation of the steam.

[0112] The aerosol-forming substrate 213 is substantially cylindrical and is located at the upstream end 217 of the consumable 202 and contains the aerosol precursor of the system 200. In this regard, the aerosol-forming substrate 213 is configured to be heated by the device 201 to release a vapour. The released vapour is then entrained in an airflow passing through the aerosol-forming substrate 213. The airflow is generated by the action of a user drawing on the downstream end 218 (i.e. the terminal end or mouth) of the consumable 202.

[0113] In the present embodiment, aerosol forms substrate 213 and comprises tobacco material, and the tobacco material can for example comprise any suitable part (for example leaf, stem, root, bark, seed and flower) of tobacco plant.Tobacco can comprise one or more tobacco leaf, tobacco stem, cigarette powder, cigarette end, tobacco derivative, expanded tobacco, homogenized tobacco, tobacco shred, extruded tobacco, shredded tobacco and / or reconstituted tobacco (for example pulp method reconstituted or paper method reconstituted).For example, aerosol forms substrate 213 and can comprise the fragment / strip of the collection of homogenized (for example paper method / pulp method reconstituted) tobacco sheet or the collection formed by such sheet.

[0114] To generate an aerosol, the aerosol-forming substrate 213 comprises at least one volatile compound that is intended to be vaporized / aerosolized and that can provide a recreational and / or medical effect to the user when inhaled. The aerosol-forming substrate 213 may also comprise one or more additives. For example, such additives may be in the form of humectants (e.g., propylene glycol and / or vegetable glycerin), flavoring agents, fillers, aqueous / non-aqueous solvents, and / or binders.

[0115] The terminal filter element 214 is also substantially cylindrical and is positioned 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 pore filter element having a hole 219 (e.g., for airflow) formed therethrough. The diameter of the hole 219 is 2 mm. The terminal filter element 214 is formed by a porous (e.g., monoacetate) filter material. As described above, the downstream end 218 of the consumable 202 (i.e., where the terminal filter 214 is positioned) forms the nozzle portion of the consumable 202 that the user inhales. The airflow is sucked from the upstream end 217 through the components of the consumable 202 and leaves the downstream end 218. The airflow is driven by the user inhaling the downstream end 218 (i.e., the nozzle portion) of the consumable 202.

[0116] The upstream filter element 215 is located between the aerosol-forming substrate 213 and the terminal filter element 214, and is axially adjacent to the aerosol-forming substrate 213. Similar to the terminal filter 214, the upstream filter element 215 is in the form of a hollow pore filter element, so that it has a hole 220 extending axially through it. In this way, the upstream filter 215 can be used as an airflow restrictor. The upstream filter element 215 is formed of a porous (e.g., monoacetate) filter material. The pores 220 of the upstream filter element 215 have a larger diameter (3 mm) than the terminal filter element 214.

[0117] The spacer 216 is in the form of a cardboard tube which defines a cavity or chamber between the upstream filter element 215 and the terminal filter element 214. The spacer 216 serves to allow cooling and mixing of the vapour / aerosol from the aerosol-forming substrate 213. The spacer has an outer diameter of 7 mm and an axial length of 14 mm.

[0118] Although not apparent in the drawings, the aerosol-forming substrate 213, the upstream filter 215 and the spacer 216 are surrounded by a paper wrap. The terminal filter 214 is surrounded by a tipping layer, which also surrounds a portion of the paper wrap (so as to connect the terminal filter 214 to the remaining components of the consumable 202). The upstream filter 215 and the terminal filter 214 are surrounded by other wrapping layers in the form of a filter plug wrap.

[0119] Now reviewing the device 201, Figure 2D Detailed view of an end portion of a device 201 configured to engage a consumable 202 is illustrated. The cap 210 of the device 201 includes an opening 221 ( Figure 2D 221 and cavity 222 are formed to accommodate at least a portion of consumable 202. During engagement of consumable 202 with device 201, a portion of consumable 202 is accommodated through opening 221 and enters cavity 222. After engagement (see Figure 2B ), the downstream end 218 of the consumable 202 protrudes from the opening 221 and therefore also from the device 201. The opening 221 includes laterally arranged notches 226. When the consumable 202 is accommodated in the opening 221, these notches 226 remain open and can, for example, be used to hold a cover to cover the end of the device 201.

[0120] Figure 2E A cross section is shown through a central longitudinal plane of the device 201. The device 201 is shown with a consumable 202 engaged therewith.

[0121] The device 201 includes a heater 204 including a heating element 223. The heater 204 forms part of the body 209 of the device 201 and is securely mounted to the body 209. In the illustrated embodiment, the heater 204 is a rod-shaped heater in which the heating element 223 has a circular transverse profile. In other embodiments, the heater may be in the form of a blade-shaped heater (e.g., a heating element having a rectangular transverse profile) or a tubular heater (e.g., a heating element having a tubular shape).

[0122] The heating element 223 of the heater 204 protrudes along the longitudinal axis from the inner base of the cavity 222 toward the opening 221. As is apparent from the drawings, the length of the heating element (i.e., along the longitudinal axis) is less than the depth of the cavity 222. In this way, the heating element 223 does not protrude from the opening 221 or extend beyond the opening 221.

[0123] When the consumable product 202 is contained in the cavity 222 (e.g. Figure 2E ), the heating element 223 penetrates the aerosol-forming substrate 213 of the consumable 202. In particular, when the heating element 223 is inserted therein, the heating element 223 extends over almost the entire axial length of the aerosol-forming substrate 213. Therefore, when the heater 204 is activated, heat is radially transferred from the outer peripheral surface of the heating element 223 to the aerosol-forming substrate 213.

[0124] The device 201 also includes an electronics cavity 224. A power source in the form of a rechargeable battery 205 (a lithium-ion battery) is located in the electronics cavity 224.

[0125] The device 201 includes a connector in the form of a USB port 206 (ie forming part of an I / O module of the device 201 ). Alternatively, the connector may be, for example, a micro USB port or a USB-C port. The USB port 206 may be used to charge the rechargeable battery 205 .

[0126] The device 201 includes a controller (not shown) located in the electronics cavity 224. The controller includes a microcontroller mounted on a printed circuit board (PCB). The USB port 206 is also connected to the controller 208 (ie, to the PCB and the microcontroller).

[0127] The controller 208 is configured to control at least one function of the device 201. For example, the controller 208 is configured to control the operation of the heater 204. Such control of the operation of the heater 204 can be achieved by the controller switching the electrical connection between the rechargeable battery 205 and the heater 204. For example, the controller 208 is configured to control the heater 204 in response to the user pressing the button 212. Pressing the button 212 can cause the controller to allow voltage (from the rechargeable battery 205) to be applied to the heater 204 (so as to cause the heating element 223 to heat).

[0128] In one aspect, the controller 208 is configured to switch the device 201 between two operating modes, namely a locked operating mode and an unlocked operating mode. In one embodiment, the controller 208 can be configured to switch the device 201 from the locked operating mode to the unlocked operating mode based on detecting the occurrence of a predetermined event or after receiving a predetermined user input. In one example, the predetermined user input for switching the device 201 from the locked operating mode to the unlocked operating mode can include a predetermined sequence of user presses or button presses on the button 212. For example, the predetermined sequence of button presses can be any of the following: (i) pressing the button 212 a predetermined number of times, such as 5 times; (ii) pressing and holding the button 212 within a predetermined time period, such as 3 seconds, or (iii) pressing the button 212 a predetermined number of times, wherein during each button press, the button 212 is kept pressed for a predetermined time period. The heater 204 of the device 201 remains disabled in the locked operating mode, for example, the heater 204 is not powered during the locked operating mode. Thus, when the controller 208 switches the device 201 from the locked mode of operation to the unlocked mode of operation, the controller 208 activates the heater 204 .

[0129] When the heater 204 is enabled during the unlocked operating state, it may not necessarily mean that the heater 204 is in an activated state (e.g., powered on), but it may also include a state in which the heater 204 is ready to receive power from a power source as long as a further user input for activating the heater 204 is received at the device 201. Therefore, in some embodiments, the heater 204 is activated only after the further user input is received from the device 201, e.g., via the UI. The predetermined user input for switching the device 201 from the locked operating mode to the unlocked operating mode is different from the further user input required to activate the heater 204 in the unlocked operating mode.

[0130] The controller 208 is also configured to switch the device 201 from the locked mode to the unlocked mode when a predetermined event (e.g., one or more predetermined conditions are met) is detected. For example, the controller 208 can be configured to switch the device 201 from the locked mode of operation to the unlocked mode of operation after detecting that the cap 210 of the device 201 is lifted off the device 201. This movement can be detected by an electronic or mechanical trigger disposed between the cap 210 and the device 201. In another example, the controller 208 can be configured to switch the device 201 from the locked mode of operation to the unlocked mode of operation after detecting that a connection is established between the device 201 and an external computing device (e.g., via a USB socket) or an external power source (e.g., a wall socket). In another example, the controller 208 can be configured to switch the device 201 from the locked mode of operation to the unlocked mode of operation after detecting that the consumables 202 are inserted in the cavity 222 of the device 201. This engagement can be detected by an electronic or mechanical trigger disposed in the cavity 222.

[0131] The predetermined event may include the occurrence of multiple events.For example, the controller 208 may be configured to switch the device 222 from the locked operating mode to the unlocked operating mode upon detecting both movement in the cap 210 and insertion of the consumable 202 in the cavity 222 .

[0132] In some embodiments, the controller 208 is configured to switch the device 201 from the locked operating mode to the unlocked operating mode in response to receiving an input from the sensor 110. The sensor 110 may be responsive to the detection of the movement of the device 201 and generate the input. In one example, the sensor 110 may be configured to generate the input when the device moves in a specific predetermined pattern. In another example, the controller 207 is configured to analyze and match the movement of the device with the predetermined pattern stored in the memory, thereby switching the device 201 from the locked operating mode to the unlocked operating mode when a positive match is registered. The predetermined movement includes, for example, one or more of a vortex movement, a waving movement or a swing movement and a longitudinal movement.

[0133] In another embodiment, the controller 208 is further configured to change from the unlocked operating mode to the locked operating mode, such as restarting the locked operating mode. In particular, the controller 208 restarts the locked operating mode in response to receiving a second predetermined user input (e.g., a second predetermined sequence of user presses at the UI). In an embodiment, the second predetermined user input that restarts the locked operating mode of the device 201 is different from the predetermined user input.

[0134] The controller 208 is also configured to control the LED 211 in response to (e.g., detecting) the state of the device 201 or the consumable 202. For example, the controller can control the LED to indicate whether the device 201 is in an on state or an off state (e.g., when the device is in an on state, one or more LEDs can be illuminated by the controller). In addition, the controller 208 can control the LED to indicate that the device 201 has switched from a locked operating mode to an unlocked operating mode, such as whether the device is in a locked operating state or an unlocked operating state. The device 201 also includes other output mechanisms, such as tactile sensors, audio sensors, etc., to provide tactile / audio feedback indicating that the device 201 has switched from a locked operating mode to an unlocked operating mode.

[0135] The device 202 also includes an input mechanism in the form of a suction sensor 225 (i.e., in addition to the button 212). The suction sensor 225 is configured to detect a user suction (i.e., inhalation) at the downstream end 218 of the consumable 202. The suction sensor 225 can, for example, be in the form of a pressure sensor, a flow meter, or a microphone. The suction sensor 225 is operably connected to the controller 208 in the electronics cavity 224, so that a signal from the suction sensor 225 indicating the suction state (i.e., suction or non-suction) forms an input to the controller 208 (and can therefore be responded to by the controller 208).

[0136] Figure 3 A flow chart illustrating a method for switching a device from a locked mode of operation to an unlocked mode of operation.

[0137] like Figure 3 As shown in , method 300 includes one or more blocks implemented by controller 208 of device 201. Method 300 can be described in the general context of controller-executable instructions. In general, controller-executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions that perform specific functions or implement specific abstract data types.

[0138] The order in which method 300 is described is not intended to be construed as limiting, and any number of the described method blocks may be combined in any order to implement method 300. Furthermore, individual blocks may be deleted from method 300 without departing from the scope of the subject matter described herein. Furthermore, method 300 may be implemented in any suitable hardware, software, firmware, or a combination thereof.

[0139] At block 301 , the controller 208 is configured to perform at least one of: receiving a predetermined user input or detecting the occurrence of a predetermined event required to switch the device from a locked mode of operation to an unlocked mode of operation.

[0140] In an exemplary embodiment, the predetermined user input to be received by the controller 208 for switching the device 201 from the locked operating mode to the unlocked operating mode may include a predetermined sequence of button presses. For example, the predetermined sequence of button presses may be any of the following: (i) pressing the button 212 a predetermined number of times, such as 5 times; (ii) pressing and holding the button 212 for a predetermined time period, such as 3 seconds, or (iii) pressing the button 212 a predetermined number of times, wherein during each button press, the button 212 is held pressed for a predetermined time period.

[0141] In another exemplary embodiment, the predetermined event for switching the device 201 from the locked operating mode to the unlocked operating mode may include multiple events or conditions. For example, the controller 208 may be configured to switch the device 201 from the locked operating mode to the unlocked operating mode after detecting that the cap 210 of the device 201 is lifted. In another example, the controller 208 may be configured to switch the device 201 from the locked operating mode to the unlocked operating mode after detecting that a connection is established between the device 201 and one of the external computing device and the external power supply. In another example, the controller 208 may be configured to switch the device 201 from the locked operating mode to the unlocked operating mode after detecting that the consumable 202 is inserted in the cavity 222 of the device 201. In box 302, the controller 208 detects whether (i) the user input matches the predetermined input stored in the memory 109, or (ii) whether the detected event matches the predetermined event previously registered / stored in the memory 109.

[0142] At block 303, the controller 208 moves along the "yes" path to switch the device from the locked mode of operation to the unlocked mode of operation. The method proceeds to block 303 only after confirming that (i) the received user input matches a predetermined user input stored in the memory 109, or (ii) the detected event matches a predetermined event registered / stored in the memory 109. The method then moves to block 304, where the controller 208 enables the heater 204 of the device 201.

[0143] However, in box 305, when (i) the user input does not match the predetermined user input stored in memory 109, or (ii) the detected event does not match the predetermined event registered / stored in memory 109, the controller 208 moves along the "no" path and does not switch the device from the locked operating mode to the unlocked operating mode.
