Description

TECHNICAL FIELD

[0001] The present application relates to the field of new tobacco technology, in particular to an aerosol generating article and a device used in conjunction therewith. BACKGROUND

[0002] Heat-not-burn cigarettes and electronic cigarettes are two new types of tobacco being developed in recent years, the main difference between the two is the type of aerosol generating article, heat-not-burn aerosol generating articles are solid materials such as cigarettes and tobacco, while electronic cigarettes are mainly aerosol generating articles such as oil and gel. However, the heating principles of the two are similar, both of which heat the aerosol generating article by electric heating or other heating methods to release the flavor components and other substances in the aerosol generating article. Since the aerosol generating article does not participate in combustion, it avoids the generation of a large amount of harmful components due to high-temperature pyrolysis at 900℃, thereby reducing harm to the body while providing satisfaction to consumers, and reducing environmental pollution. Therefore, it is favored by consumers.

[0003] The heating position is distinguished, the heating form of the aerosol generating article mainly includes internal heating, external heating and mixed heating, etc., and the heating mode is distinguished, the heating mode of the aerosol generating article can include resistance heating, electromagnetic heating, ultrasonic heating, infrared heating and other modes. The working principle of internal resistance heat-not-burn cigarettes is introduced below, taking the cigarette HEATSTICKS and the cigarette set IQOS launched by Philip Morris as an example. The cigarette set IQOS has a heating sheet inside, the heating sheet is provided with a resistance wire, when the consumer smokes, the cigarette is inserted into the cigarette set, the heating sheet pierces into the tobacco part of the cigarette, the switch of the cigarette set is started, the battery supplies power to the resistance of the heating sheet, the resistance wire is heated to bake the tobacco part of the cigarette, and the heating temperature of the heating sheet is about 300℃. During the heating process, nicotine, glycerol, propylene glycol, tobacco flavoring substances and the like are released in the form of aerosol for the consumer to smoke.

[0004] In existing heat-not-burn products, some aerosol generating devices are exclusive, and need to identify the legality of the aerosol generating article, that is, to identify whether the aerosol generating article is matched with the aerosol generating device. At present, only some aerosol generating devices have identification function, and most of them use optical identification method, that is, by scanning the optical information such as bar code, two-dimensional code and the like on the aerosol generating article to realize the identification of the legality of the aerosol generating device (some schemes also use the connection between the aerosol generating device and the handheld device, and identify the aerosol generating article through the mobile phone APP), but these methods have complex implementation process, cumbersome operation steps, and high implementation cost.

[0058] The present application is described in more detail by way of specific embodiments. Those skilled in the art will readily understand other advantages and objects of the present application from the description of the present application. Although the description of the present application will be introduced in connection with preferred embodiments, it is not intended to represent that the present application is limited to these embodiments alone. On the contrary, the description of the present application is intended to cover all possible alternatives, modifications and equivalents. In order to provide a thorough understanding of the present application, numerous specific details are described in the following description. The present application can be practiced without these details. In addition, well-known functions or constructions are not described in detail in order to avoid obscuring the present application. It should be understood that the embodiments in the present application and the features in the embodiments can be combined with each other under the condition of no conflict.

[0059] It should be noted that in the present specification, similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0060] The terms "first", "second", and the like are used only to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0061] In order to make the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0062] As shown in Figures 1 to 6 One embodiment of the present application provides an aerosol generating system, comprising: an aerosol generating article 100, a trigger portion 103 being provided on the aerosol generating article 100; and an aerosol generating device 200, the aerosol generating device 200 comprising an identification unit 1. The identification unit 1 comprises a moving assembly 10 movable between a first position and a second position, and an identification element 17, the identification element 17 being capable of identifying whether the moving assembly 10 is in the first position or in the second position. When the aerosol generating article 100 is received in the aerosol generating device 200, the trigger portion 103 causes the moving assembly 10 to be in a preset position, at which time the identification element 17 outputs an identification signal to cause the aerosol generating device 200 to heat the aerosol generating article 100. The preset position is the first position or the second position.

[0063] The scheme sets the trigger part 103 on the aerosol generating article 100, sets the corresponding recognition element 17 in the aerosol generating device, and uses the shape of the trigger part 103 to make the moving assembly 10 produce corresponding movement. Only when the aerosol generating article 100 is a legal aerosol generating article, the trigger part 103 will make the moving assembly 10 located at the preset position, at this time the recognition element 17 sends a corresponding recognition signal, so that the aerosol generating device heats the aerosol generating article 100. Compared with the existing optical recognition or handheld external device recognition, the scheme uses mechanical movement to trigger the recognition element 17. Since it does not involve complicated visual comparison or more program improvements, the recognition is simple, and the cost of the device is reduced.

[0064] For example, the recognition element 17 can be a micro switch. Specifically, the micro switch has a small contact spacing and a fast-moving mechanism, which is a contact mechanism that performs switching action with a specified stroke and a specified force. It is covered with a shell, and the outside has a transmission element. Because the contact spacing of its switch is relatively small, it is called a micro switch, also known as a sensitive switch. Specifically, external mechanical force acts on the action spring through the transmission element (such as a drive rod, a press pin, a button, a roller, etc.), and when the action spring moves to the critical point, it produces instantaneous action, so that the moving contact at the end of the action spring and the fixed contact are quickly connected or disconnected, to realize state change. When the force on the transmission element is removed, the action spring produces a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the spring, the reverse action is completed instantaneously.

[0065] Those skilled in the art can understand that in addition to the micro switch, the recognition element 17 can also be an optical coupling, a flat panel capacitor or other components. However, compared with optical coupling and other components, the micro switch involves a simpler subsequent signal output and processing process, and compared with other components, the use of the micro switch can further simplify other components in the aerosol generating device that cooperate with it, which is beneficial to simplify the structure of the aerosol generating device and reduce the cost of the device.

[0066] Specifically, the movement of the moving assembly 10 between the first position and the second position means that the upper end face of the moving assembly 10 (here, the upper end face is only relative to the Figure 2 and Figure 3The trigger portion 103 can be a protrusion, a groove, a bevel, a curved surface or other special-shaped surface provided on the surface of the aerosol generating article 100. The protrusion, groove, bevel, curved surface or other special-shaped surface provided on the surface of the aerosol generating article can make the moving assembly 10 locate at the preset position, and thus make the recognition element 17 emit the recognition signal. Alternatively, the trigger portion 103 can also be a recognition section connected with the aerosol generating substrate section, and the recognition section is provided with a protrusion, a groove, a bevel, a curved surface or other special-shaped surface. The protrusion, groove, bevel, curved surface or other special-shaped surface on the recognition section can trigger the recognition element 17 to emit the recognition signal, so as to realize the matching recognition between the aerosol generating article 100 and the aerosol generating device.

[0067] Specifically, the position of the recognition unit in the aerosol generating device is matched with the position of the trigger portion 103. Alternatively, the first position and the second position are positions close to and away from the recognition element 17, respectively. As shown in FIG. 1, Figure 2 For example, the recognition element 17 is a microswitch, Figure 2 (a) represents a schematic view of the moving assembly 10 at the second position, at which the moving assembly just contacts or still has a distance from the transmission element of the microswitch, and the microswitch is not triggered, so that the microswitch does not emit a signal or the processing module connected with the microswitch receives a low-level signal; Figure 2 (b) represents a schematic view of the moving assembly 10 at the first position, at which the moving assembly abuts against the transmission element of the microswitch, and the microswitch is triggered to output a high-level signal.

[0068] Specifically, for example, the trigger portion 103 is a protrusion. When the aerosol generating article 100 is received by the aerosol generating device, the protrusion on the surface of the aerosol generating article 100 abuts against the moving assembly 10 in the recognition unit 1, so that the moving assembly 10 moves to the preset position (at this time, the preset position is the first position) close to the recognition element 17, and thus the state of the recognition element 17 changes relative to the initial state when the aerosol generating article 100 is not received (for convenience of description below, the recognition element 17 can be defined as triggered), and at this time, the recognition element 17 emits the corresponding recognition signal, so that the aerosol generating device starts heating.

[0069] If the trigger portion 103 is a groove, the process is similar to the protrusion, but the final determination result is opposite to that of the protrusion. That is, when the trigger portion 103 is a groove, only after the aerosol generating article 100 is received, it is determined that the recognition unit is not triggered, and the aerosol generating device performs heating. That is, when the aerosol generating article 100 is received by the aerosol generating device, if the aerosol generating article 100 is a legal aerosol generating article, the position on the surface of the aerosol generating article 100 corresponding to the recognition unit is a groove. Therefore, the position of the moving assembly 10 is the same as the original position when the aerosol generating article 100 is not received, that is, the position of the moving assembly does not change at this time. The preset position at this time is the second setting away from the recognition element 17. At this time, the state of the recognition element 17 is the same as the initial state, and the recognition element 17 is not triggered. It will output an identification signal opposite to the identification signal when it is triggered, so that the aerosol generating device starts heating. That is, if the recognition element 17 emits a high-level signal when it is triggered, the recognition unit will emit a low-level signal when it is not triggered; conversely, if the recognition element 17 emits a low-level signal when it is triggered, the recognition unit will emit a high-level signal when it is not triggered. The identification signal can be a high-level signal or a low-level signal, which is set according to the type of trigger portion 103 and the type of recognition unit.

[0070] Specifically, the aerosol generating article can be a liquid. In such embodiments, the aerosol generating device further includes a liquid storage portion for storing the aerosol-forming liquid.

[0071] The liquid aerosol generating article can include nicotine. Further, the nicotine contained in the liquid aerosol generating article can be a nicotine salt base. The liquid aerosol generating article can further include a plant-based material. The liquid aerosol generating article can also include a tobacco-containing material containing volatile tobacco flavor compounds that are released from the aerosol generating article upon heating. The liquid aerosol generating article can include homogenized tobacco material, tobacco-free material, or homogenized plant-based material, etc.

[0072] The liquid aerosol generating article can include at least one aerosol former. An aerosol former is any suitable known compound or mixture of compounds that facilitates the formation of a dense and stable aerosol upon use and is substantially resistant to thermal degradation at the operating temperature of the system. Suitable aerosol formers are well known in the art and include, but are not limited to, polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate. The aerosol former can be a polyol or a mixture thereof, such as triethylene glycol, 1,3-butanediol, and glycerol. The liquid aerosol generating article can include other additives and ingredients, such as flavorings.

[0073] The aerosol generating article can include nicotine and at least one aerosol former. The aerosol former can be glycerol. The aerosol former can be propylene glycol. The aerosol former can include both glycerol and propylene glycol. For example, the aerosol generating article can have a nicotine concentration of between about 2% and about 10%.

[0074] While the above refers to a liquid aerosol generating article, it will be clear to the skilled person that other embodiments can use other forms of aerosol generating article. For example, the aerosol generating article can be a solid aerosol generating article, or the aerosol generating article can include both solid and liquid components. The aerosol generating article can include a tobacco-containing material, which contains volatile tobacco flavour compounds that are released from the substrate upon heating. The aerosol generating article can include a non-tobacco material. The aerosol generating article can further include an aerosol former. Examples of suitable aerosol formers are glycerol and propylene glycol.

[0075] If the aerosol generating article is a solid aerosol generating article, the solid aerosol generating article can include, for example, one or more of a powder, a granule, a pellet, a shard, a strand, a rod, or a sheet of material containing one or more of a herb leaf, a tobacco leaf, a tobacco rib, a reconstituted tobacco, a homogenised tobacco, an extruded tobacco, a cast leaf tobacco, and an expanded tobacco. The solid aerosol generating article can be in loose form, or can be provided in a suitable container or cartridge. Optionally, the solid aerosol generating article can contain additional tobacco or non-tobacco volatile flavour compounds that are released upon heating of the substrate. The solid aerosol generating article can also contain capsules, for example containing additional tobacco or non-tobacco volatile flavour compounds, and such capsules can melt during heating of the solid aerosol generating article.

[0076] In particular, homogenised tobacco refers to a material formed by agglomerating particulate tobacco. The homogenised tobacco can be in the form of a sheet. It can be formed by agglomerating particulate tobacco, which is obtained by grinding or otherwise comminuting one or both of tobacco lamina and tobacco stems. Alternatively or additionally, the sheet of homogenised tobacco material can include one or more of tobacco dust, tobacco fines, and other particulate tobacco by-products formed during, for example, handling, manipulation, and transportation of the tobacco. The sheet of homogenised tobacco material can include one or more inherent binders that are tobacco endogenous binders, one or more extrinsic binders that are tobacco exogenous binders, or a combination thereof, to help agglomerate the particulate tobacco; alternatively or additionally, the sheet of homogenised tobacco material can include other additives, including but not limited to tobacco and non-tobacco fibres, aerosol formers, humectants, plasticisers, flavourings, fillers, aqueous and non-aqueous solvents, and combinations thereof.

[0077] Optionally, the solid aerosol generating article can be provided on or embedded in a thermally stable carrier. The carrier can take the form of a powder, a granule, a pellet, a fragment, a fine rod, a rod or a sheet. Alternatively, the carrier can be a tubular carrier having a thin layer of solid substrate deposited on its inner surface or its outer surface or both. Such a tubular carrier can be formed from, for example, a paper or paper-like material, a non-woven carbon fibre mat, a low mass open mesh metallic screen or a perforated metallic foil or any other thermally stable polymeric substrate.

[0078] The solid aerosol generating article can also be deposited on the surface of the carrier in the form of, for example, a sheet, a foam, a gel or a slurry. The solid aerosol generating article can be deposited on the entire surface of the carrier or, alternatively, can be deposited in a pattern so as to provide for non-uniform flavour delivery during use.

[0079] Further, in the present application, the form of the heating element of each heating portion can be the same or different. The form of the heating element referred to herein includes not only the type of the heating element, but also the structure of the heating element, the setting position (end heating, internal heating, external heating, etc.) and the like. For example, one of the heating portions can adopt an internal resistance heating mode (such as a heating needle), while the other heating portion adopts an external electromagnetic heating mode (such as an electromagnetic heating tube), and of course other modes can also be adopted, which are not listed one by one herein.

[0080] Further, in the present application, the specific structure of each heating portion is not limited, and can be internal heating (such as a heating needle, a heating sheet, etc.), external heating (such as a heating tube, etc.), end heating (such as a heating disc placed at the end, etc.) or mixed heating of several modes above and the like.

[0081] Further, in the present application, the form of heating of the aerosol- generating article within each heating portion is not limited. For example, the heating element in the heating portion can be in the form of electrical resistance heating, preferably the electrical heating element comprises an electrically resistive material. Suitable electrically resistive materials include, but are not limited to, semiconductors such as doped ceramics, "conductive" ceramics (e.g. molybdenum disilicide), carbon, graphite, metals, metal alloys and composite materials made from ceramic and metallic materials. Such composite materials can comprise doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbides. Examples of suitable metals include titanium, zirconium, tantalum and platinum group metals. Examples of suitable metal alloys include stainless steel, Constantan, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminium-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys and iron-containing alloys, as well as nickel-, iron-, cobalt-based superalloys, stainless steel, iron-aluminium-based alloys and iron-manganese-aluminium-based alloys. In composite materials, the electrically resistive material can optionally be embedded in, encapsulated by or coated by an insulating material, or vice versa, depending on the kinetics of energy transfer and the desired external physico-chemical properties. The heating element can comprise a metal etched foil which acts as an insulator between two layers of inert material. In that case, the inert material can comprise a Kapton® or mica foil. Alternatively, the electric heating element can also be an infrared heating element, a photonic source or an inductive heating element, etc.

[0082] Further, the heating element can take any suitable form. For example, the electric heating element can take the form of a heating blade. The electric heating element can take the form of a sleeve or substrate with different electrically conductive portions or a resistive metal tube. If the aerosol-generating article is a liquid provided in a container, the container can incorporate a disposable heating element. One or more heating needles or rods which travel through the centre of the aerosol-generating article can be used. The electric heating element can be a disc (end) heating element or a combination of disc heating elements and heating needles or rods. The electric heating element can comprise a flexible sheet of material arranged to surround or partially surround the aerosol-generating article. Other possibilities include heating wires or filaments, for example Ni-Cr, platinum, tungsten or alloy wires, or heating plates. Optionally, the heating element can be deposited in or on a hard carrier material.

[0083] The heating element may include a heat sink or heat storage device, which includes a material that can absorb and store heat and then release the heat to the aerosol-generating article over time. The heat sink may be formed of any suitable material (such as a suitable metal or ceramic material). Preferably, the material has a high heat capacity (sensible heat storage material) or is a material that can absorb and then release heat through a reversible process (such as a high-temperature phase change). Suitable heat storage materials include silica gel, alumina, carbon, glass felt, glass fiber, minerals, metals or alloys (such as aluminum, silver or lead), and cellulose materials (such as paper). Other materials that release heat through reversible phase changes include paraffin, sodium acetate, naphthalene, wax, polyethylene oxide, metals, metal salts, eutectic salt mixtures or alloys.

[0084] The heat sink or heat storage device may be arranged so as to be in direct contact with the aerosol-generating article and may transfer the stored heat directly to the substrate. Alternatively, the heat stored in the heat sink or heat storage device may be transferred to the aerosol-generating article by means of a heat conductor (such as a metal tube).

[0085] The heating element may also heat the aerosol-generating article by conduction. The heating element may be at least partially in contact with the substrate or the carrier on which the substrate is deposited. The heat from the heating element may be conducted to the substrate through a heat conducting element.

[0086] As Figure 4 As shown, the aerosol-generating device 200 further includes a receiving cavity 30, which can receive at least part of the aerosol-generating article 100; an identification unit 1 is provided on the cavity wall 31 of the receiving cavity 30. The identification unit 1 is configured such that when the aerosol-generating article is placed in the receiving cavity 30, the triggering part 103 on the aerosol-generating article causes the identification component therein to be located at a preset position.

[0087] Exemplarily, as Figure 3 As shown, the moving component 10 includes a connecting rod 15, the first end of the connecting rod 15 is in contact with or connected to the identification element 17, and a gear structure 151 is provided on the connecting rod 15; the moving component 10 further includes:

[0088] An elastic component 16, sleeved on the connecting rod 15, one end of the elastic component 16 is in contact with or connected to the gear structure 151, and the other end of the elastic component 16 is fixed inside the aerosol-generating device 200;

[0089] Wherein, when the moving component 10 is in the first position, the elastic component 16 is in a compressed state; when the elastic component 16 is in a free state, the moving component 10 is partially located inside the receiving cavity 30. Specifically, the elastic component 16 may be a spring.

[0090] A through hole is provided on the cavity wall 31 of the receiving cavity 30, and the extending direction of the through hole is inclined or perpendicular to the extending direction of the receiving cavity 30.

[0091] Since the micro switch is generally at a distance from the accommodating cavity 30, the length of the connecting rod 15 needs to be reasonably set. However, due to the size of the space for setting the connecting rod 15, the connecting rod 15 can generally be in a strip shape. Considering the relationship between the setting length of the connecting rod 15 and its own rigidity, if it is too long, it may be accompanied by the risk of easy breakage of the connecting rod 15, affecting the service life of the device. Therefore, in some other embodiments, the end of the through hole close to the accommodating cavity 30 has a first limiting part extending into the interior of the through hole; the moving assembly 10 further comprises: a first touch piece 11, a second touch piece 13 and a second fixed cavity 14.

[0092] Specifically, the first touch piece 11 is arranged in the through hole and can move along the extension direction of the through hole, and the first limiting part is used to limit the first touch piece 11 from entering the accommodating cavity 30 completely, that is, when the elastic assembly is in a free state, the first touch piece 11 is partially located in the accommodating cavity 30; the second fixed cavity 14 is located on the side of the first touch piece 11 close to the connecting rod 15, and the interior of the second fixed cavity 14 has a second cavity extending through both ends thereof, the elastic assembly 16 is arranged in the second cavity, and the end of the second fixed cavity 14 close to the first touch piece 11 has a second limiting part extending into the interior of the second cavity; the second touch piece 13 is arranged in the second cavity and can move along the extension direction of the second cavity, and the second limiting part is used to limit the second touch piece 13 from completely leaving the second cavity, the second touch piece 13 is arranged in matching with the first touch piece 11, and one end of the second touch piece 13 is in contact with or connected to the connecting rod 15, and the second end of the connecting rod 15 is arranged in matching with the second touch piece 13.

[0093] That is, by arranging the second touch piece 13 in matching with the first touch piece 11, the setting space of the recognition assembly is reasonably considered, and the problem of easy damage caused by the overlong setting length of the connecting rod 15 is avoided.

[0094] Specifically, the shapes of the first touch piece 11 and the second touch piece 13 can be ellipsoid, cylinder, cube, arc-shaped protrusion and the like. In some embodiments of the present application, the shapes of the first touch piece 11 and / or the second touch piece 13 are spherical, more specifically, the first touch piece 11 and the second touch piece 13 can adopt spherical balls. The purpose of such arrangement is to reduce resistance and facilitate accurate placement of the aerosol generating article in the generating device, thereby facilitating further accurate recognition of the aerosol generating article.

[0095] Further, the recognition assembly 10 can further comprise a first fixed cavity 12, the first fixed cavity 12 having a first cavity extending through both ends thereof, a limiting portion being arranged at one end of the first fixed cavity 12 close to the accommodating cavity 30, and at least part of the first fixed cavity 12 being mounted in the through hole. The first touch member 11 is arranged in the first cavity and is movable along the extension direction of the first cavity. That is, the first touch member 11 is arranged in the first fixed cavity 12, and the first fixed cavity 12 is detachably mounted on the cavity wall 31 of the accommodating cavity 30. When the recognition unit 1 is damaged, the damaged recognition unit 1 and the first fixed cavity 12 in which the recognition unit 1 is arranged can be removed as a whole, so that the recognition unit 1 can be conveniently replaced, and the operation is simple.

[0096] When the recognition element is a micro switch, the first end of the connecting rod is in contact with or connected to the transmission element of the micro switch.

[0097] For example, when the first touch member 11 abuts against the protrusion of the aerosol generating article, the connecting rod 15 moves away from the accommodating cavity to trigger the micro switch, and at this time, the elastic assembly 16 is in a compressed state; when the elastic assembly 16 is in a free state, the first touch member 11 is partially located outside the first cavity.

[0098] Specifically, Figure 4 The direction of the arrow indicates the insertion direction of the aerosol generating article, the protrusion on the aerosol generating assembly is made of rigid material, and the elastic assembly 16 can be a spring. For example, Figure 8As shown, when the aerosol generating article is completely accommodated in the accommodation cavity 30 of the aerosol generating device, if the aerosol generating article can match the smoking set (i.e. the aerosol generating article is legal), at this time the rigid protrusion on the aerosol generating article will abut against the first touch element 11 in the recognition unit 1, and the first touch element 11 will drive the connecting rod 15 to move away from the accommodation cavity 30, so that the other end of the connecting rod 15 touches the transmission element of the micro switch, and the micro switch is triggered, so that the encoder 21 in the processing unit 2 can receive the signal sent by the micro switch, and the controller 22 controls the heating device to heat the aerosol generating article. Further, in this process, as the connecting rod 15 moves away from the accommodation cavity 30, the spring sleeved on the connecting rod 15 will be compressed, thereby generating a force to make the first touch element 11 move towards the accommodation cavity 30, but since the first touch element 11 abuts against the protrusion at this time, the first touch element 11 remains in this state. When the first touch element 11 does not abut against the protrusion, the first touch element 11 will not drive the connecting rod 15 to touch the transmission element of the micro switch due to the action of the spring, i.e. if the aerosol generating article is illegal, the protrusion on the aerosol generating article cannot match the recognition unit 1, and at this time the micro switch will not be triggered. The controller 22 cannot receive the recognition signal and will not control the heating device to heat the aerosol generating article. Alternatively, a display unit or a warning unit can be provided in the smoking set, and when the aerosol generating article is illegal, the controller 22 can control the display unit or the warning unit to send warning information.

[0099] Generally, one smoking set can be adapted to multiple different aerosol generating articles of the same brand, and different aerosol generating articles need to be matched with different heating curves due to different formulations, raw materials, processing techniques, etc. Therefore, in order to be able to identify the type of the aerosol generating article and select the heating parameters suitable for the type of the aerosol generating article, in some embodiments of the present application, the trigger part 103 can be arranged as protrusions or grooves arranged at intervals on the surface of the aerosol generating article, and the number of recognition units 1 is also arranged as multiple. Each recognition unit 1 can correspond to one protrusion or groove, so that the type of the aerosol generating article is identified by identifying the protrusion information or groove information (specifically, the arrangement position of the protrusion or groove) on the aerosol generating article, so as to select the appropriate heating parameters.

[0100] Specifically, the aerosol generating device further comprises a processing unit 2, and the trigger part 103 comprises multiple protrusions 1031 or grooves 1032 arranged at intervals on the surface of the aerosol generating article 100, and each protrusion 1031 or groove 1032 is arranged at a preset position on the surface of the aerosol generating article.

[0101] That is, as Figure 5As shown, in the embodiment of the present application, the trigger part 103 is an identification section with a plurality of protrusions 1031 on its surface, and the aerosol generating article is a cigarette, which is composed of a filter section 101 (which can be divided into one or more sections according to actual conditions, each section can have filtering, cooling, etc.), a tobacco section 102, and an identification section. The identification section is made of a material that is not easy to deform, such as metal, rigid plastic, paper material with appropriate thickness and hardness, and hard filter rod (such as high internal phase emulsion polymerization filter rod), etc. The identification section is centered on the central axis of the cigarette, and one or more annular protrusions 1031 are distributed around it. The position of the corresponding cigarette protrusion 1031 (cigarette identification area) in the smoking set also has one or more contact points (i.e. identification unit 1, which can be equal to or greater than the total number of protrusions 1031). When the cigarette is inserted into the smoking set, the protrusions 1031 of the cigarette come into contact with the first trigger part 11 (such as a ball bearing) in the smoking set. The protrusions 1031 on the identification section are partially transmitted to the keys (i.e. the transmission elements of the micro switch) of the identification unit 1 through the ball bearing, connecting rod 15, etc. of the identification unit 1, so that the keys are pressed down. The information of the pressed keys is transmitted to the subsequent processing module through the circuit; if there is no protrusion 1031 at the corresponding cigarette identification position, the keys are in a released state, and the information of the keys is also transmitted to the subsequent processing module through the circuit. After the information of all identification units 1 is collected, the information collection of the cigarette is completed.

[0102] With continued reference to Figure 4 , the number of identification units 1 is also multiple, and each identification unit 1 is arranged at a specified position on the cavity wall 31 of the accommodation cavity 30. Further, the number of identification units 1 is greater than or equal to the number of protrusions 1031 or grooves 1032, and each identification unit 1 is arranged at a specified position in the aerosol generating device 200 and at least part of the identification units 1 correspond to each protrusion 1031 or each groove 1032 on the surface of the aerosol generating article 100 when the aerosol generating article 100 is received in the aerosol generating device 200. That is, the number of identification units can be set in two forms: 1) the number of identification units 1 is equal to the number of protrusions 1031 (or grooves 1032), and each identification unit 1 corresponds to each protrusion 1031 (or groove 1032) on the aerosol generating device; 2) the number of identification units 1 is greater than the number of protrusions 1031 (or grooves 1032), and at least part of the identification units 1 can correspond to the protrusions 1031 (or grooves 1032) one by one.

[0103] Further, as Figure 1As shown, the processing unit 2 includes: an encoder 21, electrically connected to each identification element 17, for outputting corresponding digital signals according to the identification signals emitted by each identification element 17; and a controller 22, connected to the encoder 21, which internally stores codes and heating parameters corresponding to different types of aerosol-generated products. The controller 22 is used to compare the received digital signals with the codes stored internally to determine the heating parameters corresponding to the aerosol-generated products.

[0104] like Figure 9 As shown, during use, after the user inserts the aerosol-generating product into the smoking device, the device identifies the aerosol-generating product through the identification component and the identification program stored in the controller 22. If the identification information is legal, the device further identifies the category of the aerosol-generating product according to the identification program, selects the corresponding heating parameters (such as heating curve), and then starts heating to heat the aerosol-generating product. If the product is initially identified as an illegal aerosol-generating product, it will not be heated, and a warning message may be issued to the user.

[0105] Specifically, the number of protrusions 1031 or grooves 1032 on the surface of aerosol generating articles of the same category and the positions of the protrusions 1031 (or grooves 1032) are the same, while the positions of at least some of the protrusions 1031 (or grooves 1032) or the number of protrusions 1031 (or grooves 1032) or both the positions and the number of protrusions 1031 (or grooves 1032) are different on aerosol generating articles of different categories, so as to serve as identification features of the categories of aerosol generating articles. Taking cigarettes as an example, a certain smoking set is adapted to two different categories of cigarettes (No. 1 cigarette and No. 2 cigarette), and the positions of the marked protrusions on the No. 1 cigarette are different from those on the No. 2 cigarette, so the category of the cigarette can be determined by the difference in the positions of the marked protrusions. Specifically, the smoking set includes a plurality of identification units 1, and the positions of the identification units 1 on the cavity wall can detect all the marked protrusions on the No. 1 cigarette and the No. 2 cigarette. When the No. 1 cigarette is inserted into the smoking set, each identification unit 1 (specifically, the identification element 17 in the identification unit 1) at the corresponding position in the smoking set is triggered by each marked protrusion on the No. 1 cigarette, sends an analog signal to the encoder 21, and the encoder 21 converts the analog signals into a series of digital signals and transmits them to the controller 22 (for example, if the identification element 17 is triggered by the protrusion 1031, the single digital signal corresponding to the identification unit 1 is 1, and if the identification element 17 is not triggered by the protrusion, the single digital signal corresponding to the identification element 17 is 0), and the controller 22 compares the series of digital signals with the code stored in it to determine the category of the cigarette. For example, assume that the No. 1 cigarette and the No. 2 cigarette are each provided with four marked protrusions, three of which are provided at the same positions, and the remaining one is provided at a different position, so the identification units in the smoking set can be provided with five (identification unit C1, identification unit C2, …, identification unit C5) to identify the two types of cigarettes. For example, the four marked protrusions of the No. 1 cigarette are marked as protrusion A1, protrusion A2, protrusion A3, and protrusion A4, and the four marked protrusions of the No. 2 cigarette are marked as protrusion B1, protrusion B2, protrusion B3, and protrusion B4, wherein the positions of the protrusion A1, the protrusion A2, and the protrusion A3 of the No. 1 cigarette are the same as those of the protrusion B1, the protrusion B2, and the protrusion B3 of the No. 2 cigarette, respectively, and the position of the protrusion A4 of the No. 1 cigarette is different from that of the protrusion B4 of the No. 2 cigarette. The identification unit C1, the identification unit C2, and the identification unit C3 correspond to the protrusion A1, the protrusion A2, and the protrusion A3 (and the protrusion B1, the protrusion B2, and the protrusion B3), respectively, the identification unit C4 corresponds to the protrusion A4 of the No. 1 cigarette, and the identification unit C5 corresponds to the protrusion B4 of the No. 2 cigarette, so the two types of cigarettes can be identified by whether the identification elements in the identification units are triggered.Further, the two cigarettes correspond to different codes in the controller 22 of the smoking set respectively, the code corresponding to the No. 1 cigarette is 11110, and the code corresponding to the No. 2 cigarette is 11101. When the No. 1 cigarette is inserted into the smoking set, the recognition elements in the recognition units C1, C2, C3 and C4 are triggered by the corresponding protrusions, while the recognition element in the recognition unit C5 is not triggered, then the series of digital signals transmitted by the encoder 21 to the controller 22 is 11110, at this time, the controller 22 compares the digital signal with the codes stored in it, judges that the cigarette is the No. 1 cigarette, selects the heating parameters corresponding to the digital signal, and heats the No. 1 cigarette by using the heating parameters, which improves the efficiency of the smoking set in heating the cigarette, and further improves the taste of the generated aerosol. When the No. 2 cigarette is inserted into the smoking set, the recognition elements in the recognition units C1, C2, C3 and C5 are triggered by the corresponding protrusions, while the recognition element in the recognition unit C4 is not triggered, then the series of digital signals transmitted by the encoder 21 to the controller 22 is 11101, at this time, the controller 22 compares the digital signal with the codes stored in it, judges that the cigarette is the No. 2 cigarette, and then selects the corresponding heating parameters to heat the No. 2 cigarette by using the heating parameters.

[0106] Further, in order to further simplify the number of recognition units in the aerosol generating device, the number and position of the protrusions or grooves 1032 on each aerosol generating article can also be reasonably arranged to achieve the simplification of the number of recognition units. Still taking the aerosol generating article as a cigarette as an example, a plurality of protrusions can be arranged on the cigarette, and a certain smoking set is adapted to four different categories of cigarettes (No. 1 cigarette, No. 2 cigarette, No. 3 cigarette and No. 4 cigarette), and each of the No. 1 cigarette, No. 2 cigarette and No. 3 cigarette has four protrusions 1031, wherein the protrusions of the No. 1 cigarette are defined as protrusion A01, protrusion A02, protrusion A03 and protrusion A04; the protrusions of the No. 2 cigarette are defined as protrusion B01, protrusion B02, protrusion B03 and protrusion B04; the protrusions of the No. 3 cigarette are defined as protrusion C01, protrusion C02, protrusion C03 and protrusion C04. The No. 4 cigarette has five protrusions, which are defined as protrusion D01, protrusion D02, protrusion D03, protrusion D04 and protrusion D05. In order to further simplify the structure of the smoking set, the positions of the protrusions in the four types of cigarettes can be further processed so that only five recognition units 1 (the recognition elements in each recognition unit are defined as recognition element E01 to recognition element E05) need to be arranged in the smoking set to realize the recognition of the four types of cigarettes. There are many ways to arrange the protrusions, and only one of them is listed here. For example, the positions of the protrusions are arranged so that the recognition element E01 corresponds to the protrusion A01 of the No. 1 cigarette, the protrusion B01 of the No. 2 cigarette, the protrusion C01 of the No. 3 cigarette and the protrusion D01 of the No. 4 cigarette, respectively; the recognition element E02 corresponds to the protrusion A02 of the No. 1 cigarette, the protrusion C02 of the No. 3 cigarette and the protrusion D02 of the No. 4 cigarette, respectively; the recognition element E03 corresponds to the protrusion A03 of the No. 1 cigarette, the protrusion B02 of the No. 2 cigarette and the protrusion D03 of the No. 4 cigarette, respectively; the recognition element E04 corresponds to the protrusion A04 of the No. 1 cigarette, the protrusion B03 of the No. 2 cigarette, the protrusion C03 of the No. 3 cigarette and the protrusion D04 of the No. 4 cigarette, respectively; and the recognition element E05 corresponds to the protrusion B04 of the No. 2 cigarette, the protrusion C04 of the No. 3 cigarette and the protrusion D05 of the No. 4 cigarette, respectively. That is, the positions of the protrusion A01, the protrusion B01, the protrusion C01 and the protrusion D01 are the same; the positions of the protrusion A02, the protrusion C02 and the protrusion D02 are the same; the positions of the protrusion A03, the protrusion B02 and the protrusion D03 are the same; the positions of the protrusion A04, the protrusion B03, the protrusion C03 and the protrusion D04 are the same; and the positions of the protrusion B04, the protrusion C04 and the protrusion D05 are the same. Such arrangement can simplify the number of recognition elements in the smoking set and reduce the cost of the device.

[0107] The four types of cigarettes correspond to different codes in the controller 22 of the smoking set, the code corresponding to the first type of cigarette is 11110, the code corresponding to the second type of cigarette is 10111, the code corresponding to the third type of cigarette is 11011, and the code corresponding to the fourth type of cigarette is 11111. When the first type of cigarette is inserted into the smoking set, the recognition elements E01, E02, E03 and E04 are triggered by the corresponding protrusions, while the recognition element E05 is not triggered, then the series of digital signals transmitted by the encoder 21 to the controller 22 is 11110, at this time, the controller 22 compares the digital signal with the codes stored in it, judges that the cigarette is the first type of cigarette, selects the heating parameters corresponding to the digital signal, and heats the first type of cigarette using the heating parameters, which improves the efficiency of the smoking set in heating the cigarette, and further improves the taste of the generated aerosol. When the second type of cigarette is inserted into the smoking set, the recognition elements E01, E03, E04 and E05 are triggered by the corresponding protrusions, while the recognition element E02 is not triggered, then the series of digital signals transmitted by the encoder 21 to the controller 22 is 10111, at this time, the controller 22 compares the digital signal with the codes stored in it, judges that the cigarette is the second type of cigarette, and then selects the corresponding heating parameters to heat the second type of cigarette.

[0108] For example, the protrusions can be provided with a circular arc surface. For example, the protrusions on the aerosol generating article can be designed as ring-shaped protrusions to reduce the resistance when the aerosol generating article is inserted into the smoking set.

[0109] For example, as shown in Figure 5 and Figure 6 The trigger part 103 includes an identification section, and the surface of the identification section is provided with protrusions 1031 or grooves 1032, and the material of the trigger part 103 is a rigid material. That is, the trigger part 103 can be made of a material that is not easy to deform, such as metal, rigid plastic, paper material with appropriate thickness, and hard filter rod (such as high internal phase emulsion polymerization filter rod). Specifically, considering that metal materials are easy to dissipate heat, the trigger part 103 is preferably a non-metallic rigid material.

[0110] For example, if it is not necessary to identify the type of aerosol generating article, but only to identify whether the aerosol generating article is legal, a simpler way can also be used, for example, the trigger part 103 of the aerosol generating article is designed as a special shape. Figure 7One implementation form of an aerosol generating article is shown. Specifically, the aerosol generating article comprises, in sequence, a filter segment 101, a tobacco segment 102, and a trigger portion 103; wherein the trigger portion 103 is shaped to match the tobacco segment (such as a segment shape), and the end of the trigger portion 103 away from the tobacco segment 102 is provided with a bevel or a curved surface or a special-shaped surface; the rear end surface of the accommodating cavity 30 of the aerosol generating device matches the shape of the end of the trigger portion 103 away from the tobacco segment 102, and the recognition unit 1 is arranged on the rear end surface of the accommodating cavity 30.

[0111] That is, by designing the trigger portion 103 as a bevel, the interior of the smoking set is also designed as a bevel with the same angle, and when the bevel of the aerosol generating article matches the bevel of the interior of the smoking set, it is determined to be a legal aerosol generating article, otherwise it is an illegal aerosol generating article. This structure is relatively simple.

[0112] Correspondingly, one embodiment of the present application also provides an aerosol generating article 100 applied to the above-mentioned aerosol generating system, which has a proximal end and a distal end, and the aerosol generating article 100 comprises: an aerosol generating substrate portion and a trigger portion 103, the trigger portion 103 comprises one or more of the following: a protrusion 1031, a groove 1032, a bevel, a curved surface, and a special-shaped surface. Specifically, the proximal end is generally the mouth end, that is, the end used to contact the mouth of the consumer; the distal end is the end away from the mouth of the consumer, which is generally received in the aerosol generating device.

[0113] The skilled person will understand that the term "aerosol-generating article" is used herein to describe an article comprising an aerosol-forming substrate which can be heated to generate and deliver an aerosol to a consumer. The term "aerosol-forming substrate" denotes a substrate which is capable of releasing volatile compounds upon heating to generate an aerosol. During use, volatile compounds are released from the aerosol-forming substrate by heat transfer. The term "aerosol-generating substrate portion" denotes a portion which is made up of or comprises an aerosol-forming substrate which is capable of releasing volatile compounds upon heating to generate an aerosol. The aerosol-generating substrate portion can be a solid aerosol-generating substrate portion. The aerosol-generating substrate portion can comprise a tobacco-containing material which contains volatile tobacco flavour compounds which are released from the substrate upon heating. The aerosol-generating substrate portion can comprise a non-tobacco material. The aerosol-generating substrate portion can comprise an aerosol former. The aerosol former can comprise at least one of glycerol and propylene glycol. In embodiments in which the aerosol-generating substrate portion is a solid aerosol-generating substrate portion, the solid aerosol-generating substrate portion can comprise one or more of: a powder, a granule, a pellet, a shard, a cannelloni, a strip or a wafer, containing one or more of: a herbal leaf, a tobacco leaf, a tobacco ribbontobacco reconstitute, homogenised tobacco, extruded tobacco and expanded tobacco. The solid aerosol-generating substrate portion can be in loose form. The aerosol-generating substrate portion can comprise a rod of solid aerosol-generating substrate portion. The rod of solid aerosol-generating substrate portion can be wrapped in a wrapper. The wrapper can comprise paper.

[0114] Although reference has been made above to solid aerosol-generating articles, it will be clear to the skilled person that other embodiments can use other forms of aerosol-generating article. For example, the aerosol-generating article can be a liquid aerosol-generating article, or the aerosol-generating article can comprise both solid and liquid components.

[0115] The liquid aerosol-generating article can comprise nicotine. Further, the nicotine contained by the liquid aerosol-generating article can be a nicotine salt base. The liquid aerosol-generating article can also comprise a botanical material. The liquid aerosol-generating article can also comprise a tobacco-containing material containing volatile tobacco flavour compounds which are released from the aerosol-generating article upon heating. The liquid aerosol-generating article can comprise a homogenised tobacco material, a non-tobacco material or a homogenised botanical material, etc.

[0116] The liquid aerosol generating article can include at least one aerosol former. An aerosol former is any suitable known compound or mixture of compounds that facilitates the formation of a dense and stable aerosol upon use and is substantially resistant to thermal degradation at the operating temperature of the system. Suitable aerosol formers are well known in the art and include, but are not limited to, polyhydric alcohols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyhydric alcohols such as glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate. The aerosol former can be a polyhydric alcohol or a mixture thereof, such as triethylene glycol, 1,3-butanediol, and glycerol. The liquid aerosol generating article can include other additives and ingredients such as flavorants.

[0117] The aerosol generating article can include nicotine and at least one aerosol former. The aerosol former can be glycerol. The aerosol former can be propylene glycol. The aerosol former can include both glycerol and propylene glycol. For example, the aerosol generating article can have a nicotine concentration of between about 2% and about 10%.

[0118] Exemplarily, as shown in Figs. 1A and 1B, the aerosol generating article 100 includes a substrate portion 101 and a trigger portion 103. The substrate portion 101 is directly or indirectly connected to the trigger portion 103. The trigger portion 103 is configured to be recognized by the smoking set. Figure 5 and Figure 6 Exemplarily, as shown in Figs. 1A and 1B, the aerosol generating article 100 includes a substrate portion 101 and a trigger portion 103. The substrate portion 101 is directly or indirectly connected to the trigger portion 103. The trigger portion 103 is configured to be recognized by the smoking set.

[0119] Exemplarily, the trigger portion can be a protrusion or a groove directly provided on the surface of the aerosol generating article. Specifically, the protrusion or the groove can be provided on the surface of the substrate portion of the aerosol generating article, or on the surface of other components such as a filter segment, a cooling segment, etc., without limitation. The protrusion or the groove provided on the surface of the aerosol generating article can be annular, surrounding the surface of the aerosol generating article along the axis of the aerosol generating article, so as to reduce the resistance of the aerosol generating article when inserted into the smoking set, facilitating the insertion of the aerosol generating article.

[0120] Exemplarily, the number of the protrusions 1031 or the grooves 1032 is multiple, and each protrusion 1031 or groove 1032 is arranged on the surface of the aerosol generating article at a predetermined position.

[0121] Specifically, the material of the trigger portion 103 is a rigid material, i.e., the trigger portion 103 is made of a material that is not easy to deform, such as metal, rigid plastic, a paper material with a proper thickness and hardness, and a hard filter rod (such as a high internal phase emulsion polymerization filter rod), etc. This facilitates the recognition of the smoking set. Considering that metal materials are easy to dissipate heat, the trigger portion 103 can preferably be made of a rigid material other than metal.

[0122] Exemplarily, the aerosol generating substrate part is the tobacco segment 102; the cross-sectional shape of the triggering part 103 close to the proximal end matches the cross-sectional shape of the tobacco segment 102 close to the distal end; the tobacco segment 102 and the triggering part 103 are connected, and the bevel, the curved surface and / or the special-shaped surface are arranged at the position close to the distal end of the triggering part 103.

[0123] Exemplarily, the aerosol generating substrate part is the tobacco segment 102, and the aerosol generating article 100 further comprises the filter segment 101 at the proximal end.

[0124] As shown in Figure 7 , the aerosol generating article 100 can comprise the filter segment 101, the tobacco segment 102 and the triggering part 103 connected in sequence, and the bevel or the curved surface or the special-shaped surface is arranged at the end of the triggering part 103 away from the tobacco segment 102. Alternatively, as shown in Figure 5 and Figure 6 , the aerosol generating article 100 can be a cigarette, which is composed of the filter segment 101 (which can be divided into one or more segments according to the actual situation, and each segment can have the functions of filtering, temperature reduction, etc.), the tobacco segment 102 (i.e. the smoking segment) and the triggering part 103. The triggering part 103 comprises an identification segment, which is distributed around the center axis of the cigarette as the center, and one or more annular protrusions 1031 or grooves 1032.

[0125] Exemplarily, the triggering part 103 can be used to block the leakage of tobacco material in the tobacco segment 102; the triggering part 103 can make air flow into the tobacco segment 102.

[0126] That is, the triggering part 103 can be arranged at the distal end of the aerosol generating article to prevent the leakage of tobacco material in the tobacco segment. Moreover, the triggering part 103 can be made of a material easy to ventilate or at least one air flow channel is arranged in the triggering part to allow air to flow into the tobacco segment 102 without hindering the generated aerosol from flowing to the oral end of the consumer, thereby not causing negative effects on the smoking taste of the consumer.

[0127] The present scheme realizes the identification of the smoking set for the aerosol generating article by arranging the triggering part 103 on the aerosol generating article. The structure is simple, and the cost is low.
