Technical Field

[0002] The embodiments of the present application relate to the technical field of heat-not-burn aerosol generation technology, and in particular to an aerosol generating product, a preparation method, and an aerosol generating system. Background Art

[0003] Smoking products (e.g., cigarettes, cigars, etc.) burn tobacco to produce tobacco smoke during use. People have tried to replace these tobacco-burning products by making products that release compounds without burning. An example of such a product is a heating device that releases compounds by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products, which may or may not contain nicotine. U.S. Patent No. 5,479,948A proposes a heating device that gradually transmits partial sections or positions of an aerosol-generating substrate to a heating element for heating by transmitting a magnetic tape-like aerosol-generating substrate; such a heating device transmits heat to a magnetic tape-like aerosol-generating substrate to allow a consistent aerosol delivery amount to be accurately provided to the consumer each time.

[0163] In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

[0164] One embodiment of the present application provides an aerosol-generating article that can generate an aerosol by being heated. In some embodiments, part or all of the aerosol-generating article is intended to be consumed by a user by being heated during use.

[0165] For example, FIG1 shows a schematic diagram of an aerosol-generating article 100 according to one embodiment. In this embodiment, the aerosol-generating article 100 is generally configured in a sheet or block shape. For example, in some alternative embodiments, the aerosol-generating article 100 has a length of approximately 1 to 100 cm, a width of 2 to 30 mm, and a thickness of approximately 0.1 to 6 mm. In the embodiment of FIG1 , the aerosol-generating article 100 is configured in a square shape; in other alternative embodiments, the aerosol-generating article 100 is configured in a circular, elliptical, trapezoidal, polygonal, or other shape.

[0166] In some specific embodiments, the aerosol-generating article 100 has a length of about 5 to 10 cm, a width of about 5 to 20 mm, and a thickness of 1 to 3 mm.

[0167] In some embodiments, the aerosol-generating article 100 has an areal density of 100 to 600 g / m 2 .

[0168] In some embodiments, the aerosol-generating article 100 has a tensile strength greater than 1.5 kN / m.

[0169] In some embodiments, the aerosol-generating article 100 can be bent, folded, or rolled; thus, during use, the aerosol-generating article 100 can be bent or rolled into a desired shape by applying external force, such as into a tube shape.

[0170] In the embodiment of Figure 1 , the aerosol-generating article 100 has a laminated structure and is constructed to include a plurality of layers formed by lamination. For example, in Figure 1 , the aerosol-generating article 100 includes:

[0171] The functional layer 110 , the aerosol-generating substrate 120 and the base layer 130 are arranged in a stacked or laminated manner.

[0172] In an embodiment, the base layer 130 is thermally conductive. In a specific embodiment, for example, the base layer 130 comprises a metal or non-metal material having a suitably high thermal conductivity. In a specific embodiment, the thermal conductivity of the base layer 130 is at least 25 W / m·K, preferably at least 80 W / m·K. In a specific embodiment, the base layer 130 may comprise copper, iron, aluminum, tin, stainless steel, or an alloy containing at least one of these. In a preferred embodiment, the base layer 130 comprises an aluminum foil layer. During use, the base layer 130 can be heated directly or indirectly, for example, by thermal conduction or electromagnetic induction, which in turn heats the aerosol-generating substrate 120 to generate aerosol.

[0173] In use, the aerosol-generating article 100 is heated on one side of the base layer 130 by the heating device 300 , so that aerosol is released from the other side facing away from the base layer 130 .

[0174] In some embodiments, the base layer 130 has a thickness of approximately 0.001 to 0.2 mm; in a more preferred embodiment, the base layer 130 has a thickness of approximately 0.01 to 0.05 mm.

[0175] In some embodiments, base layer 130 is rigid or stiff.

[0176] In some preferred embodiments, the surface of the base layer 130 facing or bonding to the aerosol-generating substrate 120 is non-smooth; for example, the surface of the base layer 130 facing or bonding to the aerosol-generating substrate 120 is rough; for example, the surface of the base layer 130 of the metal or alloy foil is surface-processed by at least one process such as corona, electrochemical etching, indentation, and frosting, so that the surface of the base layer 130 forms a rough surface, such as a frosted surface; the rough surface of the base layer 130 is beneficial for maintaining a close bond with the aerosol-generating substrate 120 and preventing the base layer 130 and the aerosol-generating substrate 120 from moving relative to each other within their bonding surface.

[0177] In some embodiments, aerosol-generating substrate 120 can be used to refer to a substrate capable of releasing volatile compounds that can form an aerosol. The volatile compounds can be released to form an aerosol by heating aerosol-generating substrate 120. In some typical embodiments, aerosol-generating substrate 120 is or can include a solid at room temperature.

[0178] In some embodiments, the aerosol-generating substrate 120 may include one or more of powder, particles, shredded strips, ribbons, or flakes of one or more of herb leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; or, the solid aerosol-generating substrate 120 may contain additional tobacco or non-tobacco volatile flavor compounds to be released when the substrate is heated.

[0179] In some specific embodiments, the aerosol-generating substrate 120 may include an active substrate; the active substrate includes or is derived from one or more plant products or components thereof; for example, in some specific embodiments, the active substrate includes plant leaves, bark, fibrous tissue, stems, roots, petals, fruits, etc.; for example, in one specific embodiment, the active substrate includes or is derived from one or more plant species or components, derivatives, or extracts thereof, and the plant species is tobacco. For example, in one specific embodiment, the active substrate includes a mixture of plants such as tobacco and Chinese herbal medicine. The active substrate may include tobacco or tobacco-containing materials; for example, the active substrate may include any of the following: tobacco leaves, tobacco leaf vein segments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast leaf tobacco, and expanded tobacco.

[0180] In some optional embodiments, the aerosol-generating substrate 120 further comprises a flavorant. The flavorant may comprise a volatile flavor component. For example, in typical embodiments, the flavorant may provide a flavor selected from menthol, lemon, vanilla, orange, wintergreen, cherry, and cinnamon. The flavorant may comprise a volatile tobacco flavorant compound that is released from the aerosol-generating substrate 120 upon heating.

[0181] In some optional embodiments, the aerosol-generating substrate 120 further includes an aerosol-forming agent or a smoke-generating agent, which facilitates the formation of a dense and stable aerosol during use. In some specific embodiments, the aerosol-forming agent or a smoke-generating agent is or includes at least one of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and the like.

[0182] In some optional embodiments, the aerosol generating matrix 120 further includes: an adhesive; the adhesive promotes the bonding of the components in the aerosol generating matrix 120 during use; for example, in some specific embodiments, the adhesive is or includes at least one of gum arabic, casein, dextrin, sodium carboxymethyl cellulose, starch, polyvinyl alcohol, guar gum, etc.

[0183] In some optional embodiments, the aerosol-generating substrate 120 further comprises reinforcing fibers. The reinforcing fibers generally have a fiber strength higher than that of the tobacco plant fibers in the active substrate, thereby enhancing the strength and plasticity of the aerosol-generating substrate 120 during use. For example, in some specific embodiments, the reinforcing fibers comprise at least one of softwood fibers, hardwood fibers, hemp fibers or flax fibers, bamboo fibers, and the like.

[0184] In a specific embodiment, the aerosol-generating matrix 120 includes: 65-90 wt% of active substrate, 3-10 wt% of reinforcing fiber, 0-5 wt% of binder, 5-15 wt% of flavor, and 10-20 wt% of aerosol former or smoke generator.

[0185] Or in another specific embodiment, the aerosol generating matrix 120 includes: 65-90 wt% of active substrate, 3-10 wt% of reinforcing fiber, 0-5 wt% of adhesive, 5-15 wt% of flavor, and 15-40 wt% of aerosol former or smoke generator.

[0186] In some embodiments, the surface density of the aerosol-generating substrate 120 is 20 to 150 g / m 2 .

[0187] In some embodiments, the thickness of the aerosol-generating substrate 120 is 0.1 to 0.6 mm. In some embodiments, the thickness of the aerosol-generating substrate 120 is greater than the thickness of the base layer 130 and / or the functional layer 110. Alternatively, the thickness of the aerosol-generating substrate 120 is greater than half the thickness of the aerosol-generating article 100.

[0188] In some embodiments, the water content of the aerosol-generating substrate 120 is 6-14 wt %.

[0189] In some embodiments, aerosol-generating substrate 120 may include multiple sublayers. For example, in some optional embodiments, aerosol-generating substrate 120 may include a first sublayer and a second sublayer in a laminated or stacked arrangement. The first sublayer may include an active substrate, reinforcing fibers, an aerosol-forming agent or a smoke-generating agent, etc., while the second sublayer primarily includes a flavoring agent. During use, the first sublayer is used to generate the aerosol, while the second sublayer is used to adjust or modify the aerosol's flavor or aroma.

[0190] Alternatively, in some embodiments, the aerosol-generating substrate 120 having multiple sublayers may include a first sublayer and a second sublayer in a laminated or stacked arrangement. The first sublayer may include an active substrate, such as tobacco, and the second sublayer may include a flavoring agent and one or more functional additives such as an adhesive, a moisture barrier, a mildew inhibitor, and an antimicrobial agent. For example, the second sublayer may include 0-20 wt% of flavoring agent, 80-100 wt% of adhesive, 0-0.2 wt% of moisture barrier, 0-0.5 wt% of mildew inhibitor, and 0-0.5 wt% of antimicrobial agent.

[0191] In this embodiment, the adhesive of the second sublayer includes at least one of gum arabic, casein, dextrin, sodium carboxymethyl cellulose, starch, polyvinyl alcohol, and guar gum; the moisture-proof agent may include at least one of dimethyl fumarate, anhydrous calcium chloride, and a super absorbent resin; the mildew-proof agent includes at least one of biphenyl, o-phenylphenol, 2-pyridinethiol-1-zinc oxide, ammonium persulfate, and calcium phosphate; and the antibacterial agent may be a metal oxide or metal ion inorganic antibacterial agent.

[0192] In some other embodiments, the thickness of the second sublayer of the aerosol generating matrix 120 is 0.001 to 0.1 mm; during preparation, the second sublayer is coated on the base layer 130 by spraying, brushing, film transfer, etc., and then the first sublayer is combined with the surface of the second sublayer by rolling or casting to form a multi-sublayer aerosol generating matrix 120.

[0193] Alternatively, in yet other variations, the aerosol-generating substrate 120 may comprise a gel and / or a paste. A gel may be defined as a substantially dilute, cross-linked system that does not exhibit flow in a steady state. A paste may be defined as a viscous fluid such as a paste or slurry; for example, a paste may be a fluid that, at rest, has a dynamic viscosity greater than 1 Pa·s, 5 Pa·s, or 10 Pa·s.

[0194] In some embodiments, the functional layer 110 is dense; the functional layer 110 is used to cover the surface of the aerosol-generating substrate 120 facing away from the base layer 130 .

[0195] In one embodiment, the functional layer 110 comprises at least one of a polylactic acid film, a PE film, a PET film, a PVDC film, a food wrap, a metal foil, a paper, etc. In one aspect, the functional layer 110 is used to isolate the surface of the aerosol-generating substrate 120 facing away from the base layer 130 from the outside air to prevent the aerosol-generating substrate 120 from being oxidized or absorbing moisture.

[0196] In one embodiment, for example as shown in FIG2 , a first identifiable mark 111 is arranged on the functional layer 110; as shown in FIG2 , the first mark 111 can be arranged into a identifiable pattern; or in some other variations, the first mark 111 is a identifiable color, pattern, number, text, QR code, etc.

[0197] In some embodiments, the first identifier 111 is used to provide an identification indication related to the unique properties of the aerosol-generating article 100. A user or a heating device obtains the unique properties of the aerosol-generating article 100 by identifying the first identifier 111.

[0198] In some embodiments, the unique properties of the aerosol-generating article 100 include various information about the aerosol-generating article 100, such as authenticity information, expiration date, and place of manufacture. In some embodiments, the various information about the aerosol-generating article 100 can be obtained through the first identifier 111, thereby determining whether the aerosol-generating article 100 is authentic, when the aerosol-generating article 100 has expired, and where the aerosol-generating article 100 was manufactured. As a result, users may not inadvertently use an inauthentic aerosol-generating article 100, an expired aerosol-generating article 100, or an aerosol-generating article 100 from an unexpected source location.

[0199] In yet other embodiments, the unique properties of the aerosol-generating article 100 may include the flavor of the flavorant contained in the aerosol-generating substrate 120 , such as peach flavor, mint flavor, or orange flavor.

[0200] As another example, in some embodiments, a unique property of the aerosol-generating article 100 may include the strength of nicotine contained in the aerosol-generating substrate 120 , such as the nicotine content.

[0201] As another example, in some embodiments, the unique properties of the aerosol-generating article 100 may include an optimal heating temperature of the aerosol-generating substrate 120 .

[0202] In one embodiment, such as shown in FIG2 , the functional layer 110 is provided with several or more identifiable second markings 112 at intervals. In some embodiments, the second markings 112 are used to indicate or identify the position of the aerosol-generating article 100 when it is packaged or received in a heating device for heating. Alternatively, in still other embodiments, the second markings 112 are used to identify the heating position or heating area of ​​the aerosol-generating article 100. For example, in FIG2 , four second markings 112 are arranged at intervals along the length of the functional layer 110 to divide the aerosol-generating article 100 into five unit sections 113 arranged along the length, so that a user or device can heat the aerosol-generating article 100 by aligning a heat source or heating element with each of the five unit sections 113. Alternatively, the second markings 112 are used to indicate or identify information such as the location of the aerosol-generating article 100 that can be heated.

[0203] Alternatively, in some alternative embodiments, the first mark 111 and / or the second mark 112 are formed on or combined with the surface of the aerosol-generating substrate 120 .

[0204] In some embodiments, the functional layer 110 is flexible.

[0205] In some embodiments, the functional layer 110 is tearable or separable or removable from the aerosol-generating substrate 120 of the aerosol-generating article 100 .

[0206] In some embodiments, the thickness of the functional layer 110 made of an organic polymer material, such as a polylactic acid film, is 3 to 20 micrometers. Alternatively, in some alternative embodiments, the thickness of the functional layer 110 made of a paper material is 0.1 to 0.5 cm.

[0207] In some embodiments, the temperature resistance range of the functional layer 110 is 150-350°C.

[0208] For example, FIG3 shows a schematic diagram of the preparation of an aerosol-generating article 100 having a laminated structure in one embodiment. As shown in FIG3 , the preparation includes:

[0209] S10, laying the base layer 130 evenly on the conveyor belt 1a, and driving the base layer 130 along a predetermined direction by a mobile device such as the conveyor belt 1a; wherein the conveyor belt 1a is driven by rotating wheels to provide transmission power;

[0210] S20, preparing a slurry of the raw materials for forming the aerosol generating matrix 120, and casting the slurry onto the surface of the base layer 130 along the conveying direction of the base layer 130 by the casting device 2a, so as to form the aerosol generating matrix 120 bonded to the base layer 130;

[0211] S30 , the functional layer 110 is pressed onto the surface of the aerosol-generating substrate 120 by a pressing roller 3 a , thereby obtaining the aerosol-generating product 100 .

[0212] Alternatively, FIG4 shows a schematic diagram of the preparation of an aerosol-generating article 100 having a laminated structure according to another embodiment. As shown in FIG4 , the aerosol-generating article 100 is prepared by a multi-stage rolling process. Specifically, the multi-stage rolling process includes:

[0213] S10a, firstly, the raw material for forming the aerosol generating matrix 120 is rolled by a first pressing roller 1b to form a sheet-shaped aerosol generating matrix 120;

[0214] S20a, the base layer 130 is evenly laid on the conveyor belt 2b located downstream of the first roller wheel 1b, and the conveyor belt 2b drives the base layer 130 to be conveyed along the moving direction of the aerosol-generating substrate 120, so that the base layer 130 and the sheet-shaped aerosol-generating substrate 120 are conveyed in the same direction; wherein the conveyor belt 2b is driven by a rotating wheel in a pulley manner to provide transmission power;

[0215] S30a, using the second pressing roller 3b to press the aerosol generating substrate 120 and the base layer 130 conveyed in the same direction together by a rolling process;

[0216] S40a, using the third pressing roller 4b to press the functional layer 110 onto the surface of the aerosol generating substrate 120 by a rolling process, thereby obtaining the aerosol generating product 100.

[0217] FIG5 shows a schematic diagram of an aerosol generating system according to an embodiment. As shown in FIG5 , the aerosol generating system includes:

[0218] an aerosol-generating article 100;

[0219] The heating device 300 is used to receive the aerosol-generating article 100 and heat it to generate an aerosol for inhalation by a user.

[0220] As shown in FIG5 , the heating device 300 includes:

[0221] a rechargeable battery cell 310 for power supply;

[0222] The circuit board 32 is, for example, a PCB board or an FPC board, on which a circuit is arranged;

[0223] The heating mechanism 330 surrounds or defines a receiving cavity 340 ; in use, the aerosol-generating article 100 can be received in the receiving cavity 340 through the opening 380 on the surface of the heating device 300 to be heated or removed;

[0224] The mouthpiece 350 is in fluid communication with the receiving chamber 340 , so as to allow a user to inhale the aerosol generated by the aerosol-generating article 100 through the mouthpiece 350 .

[0225] As shown in Figure 5, the heating mechanism 330 includes multiple or several heating elements 331; and, the several heating elements 331 can be arranged on the same side of the receiving cavity 340; and when the aerosol generating article 100 is received in the receiving cavity 340, the several heating elements 331 are all facing or adjacent to the base layer 130 of the aerosol generating article 100.

[0226] In some embodiments, when the aerosol-generating article 100 is received in the receiving cavity 340 , the one or more heating elements 331 can directly or indirectly heat the base layer 130 of the aerosol-generating article 100 .

[0227] Alternatively, in some other embodiments, several or more heating elements 331 may be exposed in the receiving cavity 340; and then, when the aerosol generating article 100 is received in the receiving cavity 340, several heating elements 331 are in contact with or against the base layer 130 of the aerosol generating article 100, so that the heat generated by the heating elements 331 is conducted to the aerosol generating substrate 120 through the base layer 130.

[0228] According to the embodiment shown in FIG5 , several or more heating elements 331 are discretely arranged; for example, in FIG5 , they are arranged in an array. Accordingly, the aerosol-generating substrate 120 of the aerosol-generating article 100 includes several or more substrate units 121 that are compatible with the heating elements 331. When the aerosol-generating article 100 is received in the receiving cavity 340, the substrate units 121 can be heated by corresponding heating elements 331 to individually generate aerosol. For example, in FIG5 , the continuously arranged substrate units 121 can be approximately rectangular in shape.

[0229] In some embodiments, several or more heating elements 331 are arranged to be independently connected to the circuit board 320, and are then independently powered by the circuit board 320, thereby independently performing heating. For example, in some embodiments, several or more heating elements 331 are individually activatable, so that each heating element 331 can heat only the corresponding substrate unit 121.

[0230] In some embodiments, the circuit board 320 is configured to control the heating of the plurality of heating elements 331 to be heated one after another in a predetermined order. In some embodiments, the circuit board 320 is configured to control the heating of the plurality of heating elements 331 to be heated at different times; for example, when a user takes a puff, the circuit board 320 controls only one heating element 331 to heat and generate aerosol sufficient for one puff.

[0231] In some embodiments, in each puff, the circuit board 320 controls several heating elements 331 to independently heat the substrate unit of the aerosol-generating article 100 to produce an amount of total particulate matter (TPM) of at least 1.5 mg, at least 1.7 mg, at least 2.0 mg, at least 2.5 mg, at least 3.0 mg, about 1.0 mg to about 5.0 mg, about 1.5 mg to about 4.0 mg, about 2.0 mg to about 4.0 mg or about 2.0 mg to about 3.0 mg, at least 3 mg to about 7 mg, about 4 mg to about 8 mg, and about 5 mg to about 10 mg.

[0232] In some embodiments, the circuit board 320 controls the predetermined order in which the plurality of heating elements 331 are activated one after another. Specifically, for example, during the user's first puff, the circuit board 320 provides power to the first heating element 331 closest to the left for heating, generating aerosol for one puff. During the user's next puff, the circuit board 320 provides power to the second heating element 331 closest to the left for heating, generating aerosol for one puff. This process continues until all heating elements 331 are heated, the substrate unit of the aerosol-generating article 100 has been puffed through, and the user is prompted to replace the aerosol-generating article 100. In the above embodiments, activating the heating elements 331 individually rather than simultaneously minimizes unnecessary consumption of the aerosol-generating substrate and reduces energy waste. Alternatively, in other embodiments, the order in which the plurality of heating elements 331 are activated in the predetermined order is along the direction of the array arrangement.

[0233] Alternatively, in some alternative implementations, the circuit board 320 controls the plurality of heating elements 331 to be activated individually and sequentially, without any interval along the arrangement direction of the heating elements 331. Alternatively, in some alternative implementations, the circuit board 320 controls the plurality of heating elements 331 to be activated individually and sequentially, with intervals or in a skipped manner.

[0234] For example, in some embodiments, several or more heating elements 331 can be energized sequentially, that is, energized once each time the user takes a puff, so that aerosol is consistently generated based on each puff. Accordingly, in some embodiments, each user's puff action can be sensed by an airflow sensor, such as a microphone or MEMS sensor; and the circuit board 320 sequentially energizes several or more heating elements 331 based on the sensing results of the airflow sensor. In a preferred embodiment, the circuit board 320 controls the sequential activation of several heating elements 331 in a predetermined order, which is based on the user's puff action. And in some other variations, the circuit board 320 controls the sequential activation of several heating elements 331 at predetermined intervals; for example, the predetermined interval is between approximately 30 seconds and 300 seconds.

[0235] For example, in some other embodiments, the circuit board 320 controls the plurality of heating elements 331 to be activated sequentially in a predetermined order based on the operation input signals on the heating device 300. For example, the heating device 300 is provided with input elements, which may include switch buttons, touch screens, knobs, and other input elements that can be operated by a user to generate input signals; the circuit board 320 controls the plurality of heating elements 331 to be activated sequentially in a predetermined order based on the operation input signals generated by the user operating the input elements.

[0236] In some embodiments, the circuit board 320 controls the plurality of heating elements 331 to be activated sequentially in a predetermined order, based on the removal or replacement of the aerosol-generating article 100. Specifically, in some embodiments, after the circuit board 320 controls the activation of the plurality of heating elements 331, the user is notified that the aerosol-generating article 100 has been consumed and is prompted to replace the aerosol-generating article 100 with a new one.

[0237] Furthermore, in some embodiments, upon detecting that a new aerosol-generating article 100 has been re-received into the receiving cavity 340 of the heating device 300, the heating elements 331 are reactivated sequentially according to a predetermined sequence. Detection of a user replacing an aerosol-generating article 100 with a new one can be performed using a sensor; for example, the aerosol-generating device can be provided with a light sensor or a pressure sensor to sense the engagement or removal of the aerosol-generating article 100 into or from the receiving cavity 340, and to determine the user's replacement or consumption of the aerosol-generating article 100 based on the engagement or removal.

[0238] In some embodiments, the circuit board 320 controls the sequential activation of the heating elements 331 in a cyclic manner. For example, in some embodiments, the cycle is repeated a predetermined number of times, such as 10 times. Specifically, when the number of activations of the heating elements 331, and / or the number of puffs taken by the user, and / or the number of input signals received by the input element, reaches a predetermined number, a new cycle is entered, controlling the sequential activation of the heating elements 331.

[0239] As another example, in some embodiments, the cycle is based on the removal or replacement of the aerosol-generating article 100 .

[0240] In some embodiments, the circuit board 320 controls the heating elements 331 to heat according to the same heating curve or heating temperature. For example, in some specific embodiments, the circuit board 320 controls the heating elements 331 to heat according to a temperature of 300°C.

[0241] Alternatively, in some alternative embodiments, the circuit board 320 controls the heating of the plurality of heating elements 331 to perform heating according to different heating curves or heating temperatures. For example, in some implementations, the circuit board 320 controls the heating temperatures of the plurality of heating elements 331 to increase or decrease sequentially along the heating start sequence.

[0242] For example, in some embodiments, the circuit board 220 is configured to sequentially activate several or more heating elements 331 so that no two spatially adjacent heating elements 331 are activated consecutively. Advantageously, this can minimize preheating of the heating elements 331, which can reduce the likelihood of thermal decomposition of adjacent substrate units 121.

[0243] For example, in some embodiments, the circuit board 220 is configured to sequentially supply power to the heating element 331 at a given power level, so that the heating element 331 reaches an operating temperature within a predetermined time. For example, each time the circuit board 220 supplies power to the heating element 331, the heating element 331 reaches a temperature of at least 200°C, at least 300°C, or at least 400°C within 0.5 seconds, maintains the temperature for approximately 2.5 seconds, and then stops.

[0244] In some embodiments, the aerosol-generating article 100 may further include:

[0245] One or more color-changing status indicators 122 are combined with or arranged on one or more substrate units 121 of the aerosol generating substrate 120; the color-changing status indicators 122 can change color in response to the heating of the corresponding substrate unit 121 to provide information on whether the substrate unit 121 is in an unheated or heated use state; or, the color-changing status indicator 122 has a changeable color to provide a color indication associated with whether the substrate unit 121 is heated.

[0246] For example, in some embodiments, the color-changing status mark 122 is a graphic or pattern printed or printed on the surface of the substrate unit 121 using color-changing ink. When the substrate unit 121 is heated, the color-changing status mark 122 can change color, for example, from gray to yellow, thereby indicating that the substrate unit 121 has been heated and used. The color-changing ink can be directly purchased; in some embodiments,

[0247] Alternatively, in some alternative embodiments, the material of the aerosol-generating substrate 120 and / or the substrate unit 121 includes the aforementioned color-changing ink, etc.; and the aerosol-generating substrate 120 and / or the substrate unit 121 is configured to change color when heated, thereby providing a user with a color indication related to whether the aerosol-generating substrate 120 and / or the substrate unit 121 is heated. For example, in this embodiment, the color-changing ink is added to the raw materials of the aerosol-generating substrate 120 and / or the substrate unit 121 during preparation by doping or mixing, thereby providing the aerosol-generating substrate 120 and / or the substrate unit 121 with a color-changing color indication upon heating.

[0248] In some embodiments, the plurality of heating elements 331 may be heated by any suitable method. For example, at least one or all of the plurality of heating elements 331 may include an infrared heating element, an inductively heated magnetic field generator, a resistive heating element, or a combination thereof.

[0249] In some embodiments, the plurality of heating elements 331 are planar heating elements. In some embodiments, the plurality of heating elements 331 are configured as printed, printed, etched, deposited, or electroplated heating elements. In some embodiments, the plurality of heating elements 331 are configured as patterned heating elements, such as heating elements with a meandering, zigzag, or spiral geometric pattern.

[0250] In some embodiments, when at least one or all of the plurality of heating elements 331 comprise a resistive heating element, the resistive heating element preferably comprises a resistive material. Suitable resistive materials include, but are not limited to, conductive ceramics, carbon, graphite, metals, metal alloys, and composite materials made of ceramic and metal materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include constantan, stainless steel, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-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 at least one of superalloys based on nickel, iron, cobalt, and stainless steel.

[0251] In some embodiments, where at least one or all of the plurality of heating elements 331 comprise induction heating elements, the plurality of heating elements 331 may comprise a magnetic field generator for induction heating, generating a magnetic field to induce the substrate layer 130 of the aerosol-generating article 100 to be penetrated by the magnetic field and to generate heat, thereby heating the substrate units 121 of the aerosol-generating substrate 120. For example, the plurality of heating elements 331 may comprise an induction coil, such as a planar spiral coil, to generate a magnetic field. During use, the circuit board 220 may provide an alternating current to the plurality of heating elements 331 of the induction coil, thereby inducing the substrate layer 130 to be penetrated by the magnetic field and to generate heat, thereby heating the substrate units 121 of the aerosol-generating substrate 120. Accordingly, in this embodiment, the substrate layer 130 is a receptive metal or alloy that can be penetrated by a magnetic field and generate heat, such as 430 grade stainless steel, Permalloy, etc.

[0252] Alternatively, in some other embodiments, the plurality of heating elements 331 are optical heating elements, for example, heating the aerosol-generating article 100 by emitting infrared light, laser, etc.

[0253] FIG6 shows a schematic diagram of an aerosol-generating article 100 a suitable for light heating according to another embodiment. In this embodiment, the aerosol-generating article 100 a having a laminated structure includes:

[0254] The aerosol-generating substrate 120a, the base layer 130a and the light-absorbing layer 140a are arranged in a stacked or laminated manner.

[0255] In an embodiment, the light absorbing layer 140a may comprise a light-absorbing material; alternatively, the light absorbing layer 140a may have a reflectivity of less than 20% for infrared light, laser light, or other heating light emitted by the heating element 331, thereby allowing most of the heating light to be absorbed by the light absorbing layer 140a and converted into heat energy. Alternatively, in a more preferred embodiment, the light absorbing layer 140a may have a reflectivity of less than 10% for infrared light, laser light, or other heating light emitted by the heating element 331.

[0256] In the embodiment shown in FIG. 6 , the heating element 331 emits light for heating toward the light absorbing layer 140 a , as indicated by arrow R1 ; the light absorbing layer 140 a absorbs the light and converts it into heat energy, which in turn heats the base layer 130 , thereby ultimately heating the aerosol generating substrate 120 .

[0257] In some embodiments, the light absorbing layer 140a may be black, which is advantageous for absorbing light. For example, in some embodiments, the light absorbing layer 140a includes graphite or carbon, which is advantageous for absorbing heating light. Alternatively, the light absorbing layer 140a is or includes a carbon layer or a graphite layer.

[0258] 7 and 8 show schematic diagrams of an aerosol-generating article 100b according to yet another embodiment. In this embodiment, the aerosol-generating article 100b comprising a multi-layer structure comprises:

[0259] The base layer 130b, such as the thermally conductive metal or alloy foil described above, such as aluminum foil;

[0260] The support layer 150b is bonded to the base layer 130b. The support layer 150b is used to enhance the mechanical strength of the aerosol-generating article 100b, thereby making the aerosol-generating article 100b more rigid and reducing or preventing bending or deformation of the sheet-shaped aerosol-generating article 100b.

[0261] The aerosol-generating substrate 120b is configured to generate aerosol when heated. The aerosol-generating substrate 120b is bonded to the base layer 130b and is surrounded or placed within the support layer 150b.

[0262] In some embodiments, the thickness of the support layer 150b is greater than that of the base layer 130b, so that the support layer 150b has a higher mechanical strength. For example, the thickness of the support layer 150b is about 0.2 mm to 3 mm.

[0263] In some embodiments, the support layer 150b comprises paper. Alternatively, the support layer 150b comprises a fiber layer; the support layer 150b comprises fiber paper made of wood fiber, hemp fiber, flax fiber, bamboo fiber, etc.

[0264] As shown in Figures 7 and 8, base layer 130b is a continuous sheet or layer; and support layer 150b is a mesh-like layer; support layer 150b has a plurality of discretely arranged pores 151b. Aerosol-generating substrate 120b is arranged to include substrate units within the discretely arranged pores 151b of support layer 150b. In some embodiments, the plurality of discrete substrate units of aerosol-generating substrate 120b can be heated sequentially and independently to generate an aerosol.

[0265] As shown in FIG8 , several substrate units of the aerosol generating substrate 120 b are basically square in shape; or in some other variations, several substrate units of the aerosol generating substrate 120 b may be configured into circular, polygonal, triangular, star-shaped, semicircular, heart-shaped, cross-shaped, teardrop-shaped, and the like.

[0266] In some embodiments, the surface area of ​​the exposed surfaces of the substrate elements of the aerosol-generating substrate 120b is 4 mm 2 ~1000mm 2 In some embodiments, the thickness of the substrate unit of the aerosol-generating substrate 120b is between 0.1 mm and 10 mm. In some embodiments, the weight of the substrate unit of the aerosol-generating substrate 120b is between 5 mg and 50 mg. In some embodiments, the distance between adjacent substrate units of the aerosol-generating substrate 120b is between 0.1 mm and 20 mm.

[0267] In some embodiments, the thermal conductivity of the support layer 150b is less than 2 W / m·K, thereby providing thermal insulation between discretely arranged substrate units of the aerosol-generating substrate 120b. The thermal insulation provided by the support layer 150b is advantageous in preventing heat transfer to adjacent substrate units when one substrate unit of the aerosol-generating substrate 120b is heated. For example, in a specific embodiment, the thermal conductivity of the support layer 150b is between 0.03 and 0.07 W / m·K.

[0268] Alternatively, in some other embodiments, the first logo 111 and the second logo 112 may be arranged or formed on the surface of the support layer 150b by printing or spraying.

[0269] Alternatively, in some further embodiments, color-changeable status marks 122 may be formed or arranged on the surfaces of several discrete substrate units of the aerosol-generating substrate 120b to provide color indications related to whether the substrate units are heated.

[0270] Alternatively, in some other embodiments, the aerosol-generating article 100b may further include a tearable or removable functional layer, such as a polylactic acid film, a PE film, a PET film, etc.; the functional layer covers the exposed surface of the support layer 150b and / or the aerosol-generating matrix 120b to prevent the aerosol-generating matrix 120b from absorbing moisture, etc.

[0271] As shown in Figures 7 and 8 , the surfaces of several discrete substrate units of the aerosol-generating substrate 120b have a height difference from the surface of the support layer 150b; alternatively, the surface of the aerosol-generating substrate 120b is not flush with the surface of the support layer 150b. Specifically, the surface of the aerosol-generating substrate 120b is recessed relative to the surface of the support layer 150b. For example, the surface of the support layer 150b is at least 0.5 mm higher than the surface of the aerosol-generating substrate 120b, and more specifically, the surface of the support layer 150b is 1 to 3 mm higher than the surface of the aerosol-generating substrate 120b.

[0272] In some embodiments, the area of ​​the aerosol-generating substrate 120b comprising a plurality of substrate units accounts for at least a ratio of 0.3:1 to 0.8:1 of the area of ​​the aerosol-generating article 100b.

[0273] In some embodiments, the mass of each substrate unit of the aerosol-generating substrate 120b is approximately 5 mg to 60 mg. In some embodiments, the thickness of each substrate unit of the aerosol-generating substrate 120b is approximately 0.1 mm to 0.6 mm. In some embodiments, the exposed surface area of ​​each substrate unit of the aerosol-generating substrate 120b is approximately 9 mm. 2 ~800mm 2 .

Furthermore, the substrate units of the aerosol-generating substrate 120c and the base layer 130c are supported or retained by the support layer 150c.

[0282] In the aerosol-generating article 100c of this embodiment, the base layer 130c is embedded in or located within the pores 151c of the support layer 150c. Alternatively, in some other embodiments, the support layer 150c is inserted into or embedded within the base layer 130c.

In use, the substrate units of the aerosol generating substrate 120d can receive heat from the base layer 130d and be heated.

[0286] In the aerosol-generating article 100d of this embodiment, the substrate units of the aerosol-generating substrate 120d are respectively accommodated and held in the blind holes 131d of the base layer 130d, and are supported and heated.

[0287] Alternatively, FIG12 shows a schematic diagram of an aerosol-generating article 100e according to another alternative embodiment; in this embodiment, the aerosol-generating article 100e having a multi-layer structure includes:

[0288] The thermally conductive base layer 130e is, for example, made of the metal or alloy described above;

[0290] The mesh support layer 150e has a plurality of discrete and equally arranged pores 151e; the support layer 150e is bonded to the aerosol-generating substrate 120e by rolling or other means; by rolling or pressing, the support layer 150e is partially embedded from the surface of the aerosol-generating substrate 120e into the aerosol-generating substrate 120d; and the aerosol-generating substrate 120e is at least partially embedded in the pores 151e of the support layer 150e, thereby defining the substrate units located within the pores 151e.

[0291] Specifically, as shown in FIG12 , the aerosol generating substrate 120e includes:

[0292] The first portion 1210e includes a plurality of matrix units discretely located within the pores 151e of the support layer 150e;

[0293] The second portion 1220e is located between the support layer 150e and the base layer 130e and is used to provide adhesion between the support layer 150e and the base layer 130e.

[0294] Another embodiment of the present application further provides an aerosol generating system, as shown in FIG13 and FIG14 , the aerosol generating system includes:

[0295] Aerosol-generating article 100f;

[0296] The heating device 300f is used to receive the aerosol-generating article 100f and heat it to generate an aerosol for the user to inhale. The heating device 300f includes:

[0297] a receiving chamber 340f for receiving the aerosol-generating article 100f;

[0298] The heating mechanism 330f at least partially surrounds, defines or is adjacent to the receiving cavity 340f; in use, the aerosol generating article 100f can be received in the receiving cavity 340f through the opening 380f on the surface of the heating device 300f and heated, as shown by arrow P3 in FIG13 .

[0299] According to the embodiment shown in FIG. 13 and FIG. 14 , the aerosol-generating article 100 f is essentially a multi-layer structure and includes:

[0300] The base layer 130f, the support layer 150f and the aerosol-generating substrate 120f; wherein the aerosol-generating substrate 120f includes a plurality of discretely arranged substrate units; the support layer 150f is substantially in a mesh shape for surrounding and separating the substrate units of the aerosol-generating substrate 120f.

[0301] As shown in FIG13 and FIG14 , the aerosol generating article 100f further includes:

[0302] The holding region 152f is used to stably hold the aerosol-generating article 100f in the receiving cavity 340f of the heating device 300f by clamping or abutting against the holding region 152f when the aerosol-generating article 100f is received in the receiving cavity 340f of the heating device 300f. The substrate units of the aerosol-generating substrate 120f avoid the holding region 152f, or there are no substrate units of the aerosol-generating substrate 120f on the holding region 152f.

[0303] In the embodiments shown in Figures 13 and 14 , the retaining region 152f may be indicated or defined by a connection structure disposed on the aerosol-generating article 100f. For example, in Figures 12 and 13 , the retaining region 152f is provided with a connection structure that can be connected to the retaining structure 341f on the heating device 300f, thereby retaining the aerosol-generating article 100f by forming a connection with the retaining structure 341f. For example, in some embodiments, the retaining structure 341f on the heating device 300f may be, for example, a pressing protrusion or a clamping rod; correspondingly, the retaining region 152f may be provided with a matching indentation or hole to facilitate the connection. Alternatively, in further alternative embodiments, the retaining region 152f may be formed or defined on the support layer 150f; and the retaining region 152f may be configured to have a different color than other portions of the support layer 150f, thereby facilitating user identification or manipulation.

[0304] As shown in Figures 13 and 14, the holding area 152f is close to both sides of the aerosol generating article 100f in the length direction; for example, the holding area 152f includes a first holding area arranged near the first end of the aerosol generating article 100f in the length direction, and a second holding area arranged near the second end of the aerosol generating article 100f in the length direction; and, several discrete substrate units of the aerosol generating substrate 120f are located between the first holding area and the second holding area.

[0305] Accordingly, the retaining structure 341f on the heating device 300f includes a first retaining structure arranged near a first end of the receiving cavity 340f in the longitudinal direction and a second retaining structure arranged near a second end of the receiving cavity 340f in the longitudinal direction.

[0306] In some embodiments, the retaining structure 341f is arranged in the receiving cavity 340f away from the heating mechanism 330f, so that the retaining structure 341f can squeeze or fix the aerosol generating article 100f toward the heating mechanism 330f; thereby, the aerosol generating article 100f, mainly the base layer 130f, remains in contact with or conducts heat to the heating mechanism 330f.

[0307] As shown in FIG13 and FIG14 , the heating mechanism 330f of the heating device 300f includes:

[0308] A plurality of heating elements 331f are provided; the plurality of heating elements 331f may be arranged on the same side of the receiving cavity 340f; and when the aerosol-generating article 100f is received in the receiving cavity 340f, the plurality of heating elements 331f are all oriented toward or adjacent to the base layer 130f of the aerosol-generating article 100f. When the aerosol-generating article 100f is received in the receiving cavity 340f, the plurality of heating elements 331f are respectively aligned with the substrate units of the aerosol-generating substrate 120f; thereby, in use, the substrate units of the aerosol-generating substrate 120f can be independently heated by the opposing heating elements 331f.

[0309] Alternatively, in some embodiments, the plurality of heating elements 331f are configured to sequentially start heating one by one, thereby sequentially heating the substrate units of the aerosol-generating substrate 120f one by one to generate aerosol.

[0310] Alternatively, in this embodiment, the aerosol-generating article 100f further comprises:

[0311] One or more color-changing status indicators are used to provide a color indication associated with whether the substrate unit of the aerosol-generating substrate 120f is heated. In an embodiment, the one or more color-changing status indicators are color-changing patterns or identifiable marks formed on or incorporated into the substrate unit of the aerosol-generating substrate 120f; such patterns change color in response to heating of the corresponding substrate unit of the aerosol-generating substrate 120f, thereby indicating whether the substrate unit of the aerosol-generating substrate 120f is in an unheated or heated state of use. For example, in some embodiments, the color-changing status indicator is a pattern or design printed or formed on the surface of the substrate unit using color-changing ink. When the substrate unit is heated, the color-changing status indicator changes color, for example, from gray to yellow, thereby indicating that the substrate unit has been heated for use.

[0312] FIG15 shows a schematic diagram of an aerosol generating system according to an embodiment. In this embodiment, the aerosol generating system comprises:

[0313] an aerosol-generating article 100 g; and,

[0314] The heating device 300g is used to receive the aerosol-generating product 100g and heat it to generate an aerosol for the user to inhale.

[0315] As shown in FIG15 , the aerosol-generating article 100 g includes:

[0316] The operating portion 1100g and the aerosol generating portion 1200g are arranged sequentially along the width direction of the aerosol generating article 100g;

[0317] The aerosol generating portion 1200g is mainly used to be received in the receiving cavity 340g of the heating device 300g for heating to generate aerosol;

[0318] The operating part 1100g is operated by the user, for example, by pinching it with fingers, so as to receive the aerosol generating part 1200g into the receiving cavity 340g or remove it from the receiving cavity 340g; and in use, the operating part 1100g is not received in the receiving cavity 340g of the heating device 300g, or the operating part 1100g is exposed outside the receiving cavity 340g of the heating device 300g.

[0319] As shown in FIG. 15 , for the sheet-shaped aerosol-generating article 100 g , the thickness of the operating portion 1100 g is greater than the thickness of the aerosol-generating portion 1200 g .

[0320] As shown in Figure 15, the aerosol-generating substrate 120g of the aerosol-generating article 100g is arranged to be located on the aerosol-generating part 1200g and avoid the operating part 1100g; and, the holding area 152g of the aerosol-generating article 100g can be on the aerosol-generating part 1200g and avoid the operating part 1100g.

[0321] 15 , the base layer 130g of the aerosol-generating article 100g extends from the operating portion 1100g to the aerosol-generating portion 1200g. Similarly, the support layer 150g of the aerosol-generating article 100g extends from the operating portion 1100g to the aerosol-generating portion 1200g.

[0322] 15 , the receiving chamber 340g has a first sidewall 3410g proximate to or adjacent to the heating mechanism 330g and / or the heating element 331g, and a second sidewall 3420g facing away from the heating mechanism 330g and / or the heating element 331g. When the aerosol-generating article 100g is received in the receiving chamber 340g, the aerosol-generating article 100g abuts against or fits against the first sidewall 3410g of the receiving chamber 340g. Furthermore, a gap exists between the aerosol-generating article 100g and the second sidewall 3420g of the receiving chamber 340g, defining at least a portion of an aerosol output channel for outputting the aerosol generated by the heated aerosol-generating substrate 120g.

[0323] FIG16 shows an aerosol generating system according to yet another embodiment, in which the aerosol generating system comprises:

[0324] Aerosol generating article 100h, and heating device 300h. Of which:

[0325] The aerosol generating product 100h includes an operating part 1100h and an aerosol generating part 1200h; the aerosol generating part 1200h is mainly used to be received in the receiving cavity 340h of the heating device 300h for heating to generate an aerosol; the operating part 1100h is operated by the user, for example, by pinching it with fingers, so as to receive the aerosol generating part 1200h into the receiving cavity 340h of the heating device 300h or remove it from the receiving cavity 340h of the heating device 300h; and in use, the operating part 1100h is not received in the receiving cavity 340h of the heating device 300h, or the operating part 1100h is exposed outside the receiving cavity 340h of the heating device 300h.

[0326] The heating device 300h comprises:

[0327] a heating mechanism 330h adjacent to or at least partially defining the receiving cavity 340h; the heating mechanism 330h includes a plurality of heating elements 331h arranged longitudinally along the receiving cavity 30h, for heating the aerosol-generating portion 1200h of the aerosol-generating article 100h received in the receiving cavity 340h to generate an aerosol;

[0328] The air inlet 360h is in airflow communication with the receiving chamber 340h, thereby supplying air into the receiving chamber 340h during suction;

[0329] The mouthpiece 350h is in fluid communication with the receiving chamber 340h, and is configured for a user to inhale the aerosol generated by the aerosol-generating article 100h through the mouthpiece 350h.

[0330] 16 to 18 , the aerosol-generating article 100h has a laminated structure or a multi-layer structure; and the aerosol-generating article 100h includes:

[0331] Thermally conductive base layer 130h, support layer 150h, and aerosol-generating substrate 120h.

[0332] In this embodiment, a plurality of discretely arranged holes 151h are arranged on the support layer 150h; the aerosol-generating substrate 120h includes a plurality of substrate units discretely arranged within the holes 151h.

[0333] In the embodiments shown in Figures 16 to 18 , there is a spacing between the substrate units of the aerosol-generating substrate 120h and the inner sidewalls of the aperture 151h, such as spacing d1 and spacing d2 shown in Figure 18 . Spacing d1 and / or spacing d2 are approximately 1-2 mm. Furthermore, a spacing space 153h is defined between the substrate units of the aerosol-generating substrate 120h and the inner sidewalls of the aperture 151h. Spacing space 153h is approximately annular and surrounds the substrate units of the aerosol-generating substrate 120h. During use, aerosol generated by the heated substrate units of the aerosol-generating substrate 120h is released into spacing space 153h and then delivered to the mouthpiece 350h along with the inhalation airflow for inhalation by the user.

[0334] As shown in Figures 16 to 18 , the aerosol-generating article 100h includes a first side 11h and a second side 12h that are opposite to each other along the width direction. The operating portion 1100h is adjacent to or bounds the first side 11h, and the aerosol-generating portion 1200h is adjacent to or bounds the second side 12h. Furthermore, the aerosol-generating substrate 120h is located within the aerosol-generating portion 1200h and is relatively closer to the second side 12h. Furthermore, as shown in Figures 16 to 18 , the spacing 153h surrounding the substrate units of the aerosol-generating substrate 120h is open on the second side 12h to facilitate aerosol delivery. For example, as indicated by arrow R2 in Figure 18 , aerosol within the spacing 153h exits the second side 12h and is delivered to the mouthpiece 350h along with the airflow.

[0335] Alternatively, in some embodiments, the heating device 300h further includes an airflow channel defining an airflow path from an air inlet 360h through the receiving cavity 340h to the mouthpiece 350h, thereby delivering the aerosol to the mouthpiece 350h. In some embodiments, when the aerosol-generating article 100h is received in the receiving cavity 340h and heated to generate an aerosol, the airflow channel of the heating device 300h at least partially flows through the second side 12h of the spacing space 153h. Alternatively, in some embodiments, when the aerosol-generating article 100h is received in the receiving cavity 340h and heated to generate an aerosol, the spacing space 153h and the airflow channel of the heating device 300h are in fluid communication.

[0336] In some embodiments, the spacing spaces 153h are further configured to provide thermal insulation outside the substrate units of the aerosol-generating substrate 120h to prevent heated substrate units of the aerosol-generating substrate 120h from transferring heat to adjacent substrate units.

[0337] As shown in Figures 16 to 18, the plurality or several spacing spaces 153h surrounding the substrate unit of the aerosol-generating substrate 120h are separated from each other and are not connected.

[0338] Alternatively, FIG. 19 shows a schematic diagram of an aerosol-generating article 100j according to another alternative embodiment; in this embodiment, the aerosol-generating article 100j comprises:

[0339] Base layer 130j;

[0340] a support layer 150 j , bonded to the base layer 130 j and provided with a plurality of discretely arranged holes 151 j ;

[0341] an aerosol-generating substrate 120 j comprising a plurality of substrate units disposed within the aperture 151 j and capable of being heated by the base layer 130 j to generate an aerosol;

[0342] The aerosol-generating article 100j further comprises:

[0343] The spacing space 153j surrounds the substrate unit of the aerosol generating substrate 120j to provide thermal insulation; alternatively, the spacing space 153j is used to accommodate the aerosol generated by heating the substrate unit of the aerosol generating substrate 120j; the spacing space 153j is defined between the inner side wall of the hole 151j of the support layer 150j and the substrate unit.

[0344] The aerosol-generating article 100j further comprises:

[0345] The aerosol output channel 154j is in communication with the spacing space 153j, thereby outputting the aerosol in the spacing space 153j to the outside of the aerosol generating article 100j or to the nozzle 350h of the heating device 300h.

[0346] In this embodiment, several or more spacing spaces 153j are connected to each other through aerosol output channels 154j.

[0347] Alternatively, in some alternative embodiments, the number of aerosol output channels 154j may be greater, such as two, three, or more. For example, FIG. 20 shows another embodiment in which a plurality of spacing spaces 153k defined between a support layer 150k of an aerosol-generating article 100k and substrate units of an aerosol-generating substrate 120k are connected via two aerosol output channels 154k to output aerosol.

[0348] Alternatively, FIG. 21 shows a schematic diagram of another variant embodiment in which a plurality of spacing spaces 153 m on a support layer 150 m of an aerosol generating article 100 m are arranged on both sides of the width of an aerosol output channel 154 m and connected to output aerosol.

[0349] Alternatively, in another embodiment shown in FIG. 22 , a plurality of spacing spaces 153 n on the support layer 150 n of the aerosol-generating article 100 n output aerosol independently through their respective connected aerosol output channels 154 n while avoiding other spacing spaces 153 n.

[0350] In the above embodiments, the aerosol output channels 154j / 154k / 154m / 154n are configured to extend straight, and the width of the aerosol output channels 154j / 154k / 154m / 154n is substantially constant, and the aerosol output channels 154j / 154k / 154m / 154n extend along the length or width of the aerosol-generating article 100j / 100k / 100m / 100n. In other alternative embodiments, the aerosol output channels 154j / 154k / 154m / 154n may extend in a curved, bent, or serpentine manner, or in a straight, zigzag, or arcuate manner, and the width of the aerosol output channels 154j / 154k / 154m / 154n may vary, for example, at least partially increase or decrease.

[0351] Alternatively, FIG. 23 to FIG. 25 show schematic diagrams of an aerosol-generating article 100 p according to another alternative embodiment. In this embodiment, the aerosol-generating article 100 p having a multi-layer structure includes:

[0352] Base layer 130p;

[0353] an aerosol-generating substrate 120p, bonded to a base layer 130p;

[0354] The support layer 150p includes a plurality of discrete support units; each support unit is roughly in the shape of a frame having a central hole 151p; each support unit of the support layer 150p is bonded to the aerosol generating matrix 120p by pressing such as rolling, and is at least partially embedded in the aerosol generating matrix 120p, as shown by arrow P3 in FIG23 .

[0355] In the aerosol-generating article 100p formed after lamination, the aerosol-generating substrate 120p embedded with the support layer 150p comprises:

[0356] A plurality of substrate elements 121p are located within the pores 151p of the support elements of the support layer 150p; and exposed elements 122p are located between the support elements of the support layer 150p. During use, both the substrate elements 121p and the exposed elements 122p of the aerosol-generating substrate 120p can be heated by the base layer 130p to generate aerosols. The aerosols generated by the heated substrate elements 121p escape directly from the surface and are then released from the pores 151p of the support elements of the support layer 150p. The aerosols generated by the exposed elements 122p are released from between the support elements of the support layer 150p.

[0357] 26 and 27 show schematic diagrams of an aerosol-generating article 100q according to yet another alternative embodiment. In this embodiment, the aerosol-generating article 100q is in the shape of an elongated sheet. The aerosol-generating article 100q includes:

[0358] An operating portion 1100q and an aerosol generating portion 1200q; wherein, an aerosol generating matrix 120q is arranged on the aerosol generating portion 1200q; the aerosol generating matrix 120q may include a plurality of discrete matrix units bonded to a base layer 130q, thereby being heated by receiving heat from the base layer 130q to generate an aerosol; the operating portion 1100q is used for operation by the user's fingers, etc., so as to receive the aerosol generating product 100q in the receiving cavity 340q of the heating device 300q for heating or removal.

[0359] As shown in FIG. 26 and FIG. 27 , the aerosol-generating article 100q further includes:

[0360] The detectable identification element 160q is arranged on the operating portion 1100q. The detectable identification element 160q can be a pattern, graphic, color, QR code, or an identifiable mechanical structure, electronic device, etc. arranged on the operating portion 1100q.

[0361] In some specific embodiments, the detectable identification element 160q can be a transparent pattern or coating that is printed or sprayed.

[0362] 28 and 29 show schematic diagrams of a heating device 300q adapted for use with the aerosol-generating article 100q. As shown in FIG. 28 and FIG. 29 , the heating device 300q comprises:

[0363] a receiving chamber 340q for receiving the aerosol-generating portion 1200q of the aerosol-generating article 100q;

[0364] The detection unit 370q, such as a detection device such as a light sensor, a camera, or a color sensor, can be arranged near an opening on the surface of the heating device 300q to detect the detectable identification element 160q of the aerosol-generating article 100q, thereby determining whether the aerosol-generating article 100q is accurately received in or removed from the receiving cavity 340q.

[0365] In some specific embodiments, the detection unit 370q is a camera, which determines whether the aerosol-generating article 100q is accurately received in the receiving cavity 340q by identifying the detectable identification element 160q of the transparent pattern or coating.

[0366] As shown in Figures 26 to 29 , a receiving position indicator 170q is disposed on the surface of the aerosol-generating article 100q, for example, on a detectable identification element 160q. For example, in this embodiment, the receiving position indicator 170q is a visual indicator that prompts a user that the aerosol-generating article 100q is correctly received in the receiving cavity 340q of the heating device 300q. For example, in this embodiment, the receiving position indicator 170q is an indicator line formed by printing or stamping. When the aerosol-generating article 100q is correctly received in the receiving cavity 340q of the heating device 300q, the indicator line is substantially flush with the opening or surface of the heating device 300q. Thus, the user can confirm that the aerosol-generating article 100q is correctly received in the receiving cavity 340q of the heating device 300q by confirming that the indicator line is flush with the opening or surface of the heating device 300q.

[0367] For example, as shown in Figure 28, when the user pinches the operating part 1100q of the aerosol generating product 100q with his fingers and receives the aerosol generating part 1200q into the receiving cavity 340q of the heating device 300q along the operating direction indicated by the arrow P4 in Figure 28; when the detection unit 370q detects the presence of the detectable identification element 160q, it is determined that the aerosol generating part 1200q has been correctly received in the receiving cavity 340q of the heating device 300q.

[0368] Accordingly, the heating device 300q is configured as follows:

[0369] When the detection unit 370q detects the presence of the detectable identification element 160q, power is allowed to be supplied to the heating element to heat the aerosol generating portion 1200q to generate aerosol. When the detection unit 370q detects the absence of the detectable identification element 160q, power is blocked from being supplied to the heating element.

[0370] In the embodiment shown in Figures 26 to 29, the operating portion 1100q of the aerosol-generating article 100q is formed by the base layer 130q and the support layer 150q extending from the aerosol-generating portion 1200q. Therefore, during manufacture, it is only necessary to leave the base layer 130q and the support layer 150q sufficiently longer, and to define the operating portion 1100q by a portion thereof.

[0371] In the embodiments shown in Figures 26 to 29 , the substantially sheet-like or block-like aerosol-generating article 100q is asymmetrical along at least one of its length or width, which is advantageous for user orientation or foolproofing. For example, in the embodiments shown in Figures 26 to 29 , the left end of the aerosol-generating article 100q along its length has a straight edge, while the left end along its length has a curved edge; thus, the aerosol-generating article 100q is asymmetrical along its length.

[0372] Alternatively, FIG30 shows a schematic diagram of an aerosol-generating article 100r according to another alternative embodiment; in this embodiment, the aerosol-generating article 100r comprises:

[0373] Operation portion 1100r and aerosol generating portion 1200r: In this embodiment, the operation portion 1100r and the aerosol generating portion 1200r are separately manufactured and then fastened together by bonding or mechanical connection.

[0374] For example, in the embodiment shown in Figure 30 , the aerosol-generating portion 1200r includes a base layer 130r, a support layer 150r, and an aerosol-generating matrix 120r, all of which are produced through the aforementioned rolling and casting processes. The operating portion 1100r includes a detectable identification element 160r and a substrate 170r. For example, the substrate 170r is made of a separate material such as organic polymer plastic or metal, and the identification element 160r is a detectable pattern, coating, or QR code with a recognizable color formed on or bonded to the substrate 170r.

[0375] According to the embodiment shown in FIG30 , the thickness of the operating portion 1100r is greater than that of the aerosol-generating portion 1200r, making the aerosol-generating portion 1200r asymmetric in the thickness direction, thereby providing foolproof identification. This facilitates user identification of the front and back directions of the aerosol-generating portion 1200r in the thickness direction by the difference in thickness. For example, in the embodiment shown in FIG30 , the user can identify the top surface of the aerosol-generating article 100r by the fact that the top surface of the operating portion 1100r in the thickness direction is more protruding.

[0376] In some embodiments, the heating device 300q has an opening size such that the aerosol-generating portion 1200r of the aerosol-generating article 100r can be inserted or received in the receiving cavity 340q through the opening, and prevents the operating portion 1100r from being inserted or received in the receiving cavity 340q through the opening.

[0377] Alternatively, Figure 31 shows a schematic diagram of another variant embodiment of a basically sheet-shaped or block-shaped aerosol-generating product 100s; in this embodiment, the base layer 130s of the aerosol-generating product 100s is more prominent at the left end in the longitudinal direction than the support layer 150s and / or the aerosol-generating matrix 120s, thereby making the aerosol-generating product 100s asymmetric along the longitudinal direction, which is beneficial for users to identify the direction or provide anti-foolproofing.

[0378] Based on the shape or structure of the aerosol-generating article 100s and the base layer 130s made of metal or alloy, another embodiment of the present application provides a heating device comprising a disconnected loop or two conductive elements. When the aerosol-generating article 100s is received in the heating device, a protruding portion of the base layer 130s at the left end in the longitudinal direction of the aerosol-generating article 100s is conductively connected to the loop or the two conductive elements, thereby maintaining electrical continuity in the loop or the two conductive elements. Furthermore, the heating device detects whether the loop or the two conductive elements are connected or disconnected to determine whether the aerosol-generating article 100s is received or removed from the heating device.

[0379] FIG32 shows a schematic diagram of an aerosol-generating article 100t according to yet another embodiment. In this embodiment, the aerosol-generating article 100t includes a substantially annular or circular aerosol-generating portion 1200t and an operating portion 1100t extending radially outward from the aerosol-generating portion 1200t.

[0380] The operating portion 1100t includes a detectable identification element 160t and a substrate 170t; for example, the substrate 170t is made of an independent material such as organic polymer plastic or metal, and the identification element 160t is a detectable pattern, coating, or QR code with a recognizable color formed on or bonded to the substrate 170t;

[0381] The aerosol generating portion 1200t includes a substrate (not shown in the figure) and a support layer 150t bonded to the substrate; the support layer 150t includes a plurality of portions circumferentially arranged around the aerosol generating portion 1200t, each portion having a hole 151t arranged therein; the aerosol generating substrate 120t includes a plurality of substrate units discretely arranged on a plurality of portions of the support layer 150t to generate aerosol by receiving heat from the substrate.

An operating portion 1100 t is configured to be gripped by a user's finger, for example, to provide an operation, thereby receiving the aerosol-generating portion 1200 t in the receiving cavity of the heating device. Furthermore, the user can operate the aerosol-generating portion 1200 t via the operating portion 1100 t, thereby driving the aerosol-generating portion 1200 t to rotate about a virtual center O within the receiving cavity. Accordingly, the receiving cavity of the heating device may be circular, thereby allowing the aerosol-generating portion 1200 t to rotate about the virtual center O within the receiving cavity. Accordingly, the heating device further includes a detection unit, such as a light sensor, a camera, a color sensor, or other detection device, for detecting a detectable identification element 160 t of the operating portion 1100 t, thereby confirming that the aerosol-generating portion 1200 t is accurately received in the receiving cavity. For example, when the aerosol generating part 1200t rotates to the point where the detection unit can detect the detectable identification element 160t of the operating part 1100t, a prompt such as vibration or light is issued to prompt the user that the aerosol generating part 1200t is accurately received in the receiving cavity.
