Description

[0001] This application claims priority to Chinese Patent Application No. 202311148972.0, entitled "AEROSOL GENERATING PRODUCT, PREPARATION METHOD, AND AEROSOL GENERATING SYSTEM" filed with the China National Intellectual Property Administration on September 5, 2023, which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] Embodiments of this application relate to the field of heat-not-burn aerosol generating technologies, and in particular, to an aerosol generating product, a preparation method, and an aerosol generating system.BACKGROUND

[0003] Tobacco is burnt to produce tobacco smoke during use of tobacco products (such as cigarettes and cigars). Attempts are made to replace these tobacco-burning products by manufacturing products that release compounds without being burnt. An example of the products is a heating apparatus that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products, and the non-tobacco products may or may not include nicotine. The U.S. patent US5479948A discloses a heating apparatus for transmitting a tape-type aerosol generating substrate to progressively transmit part of sections or positions of the aerosol generating substrate to a heating element for heating. The heating apparatus delivers a consistent amount of aerosol to consumers each time by heating the tape-type aerosol generating substrate in a transmission manner.SUMMARY

DETAILED DESCRIPTION

[0098] To facilitate the understanding of this application, this application is described in more detail below with reference to accompanying drawings and specific implementations.

[0099] An embodiment of this application provides an aerosol generating product, which can be heated to generate aerosol. In some embodiments, part or all of the aerosol generating product is intended to be consumed by a user by heating during use.

[0100] For example, FIG. 1 is a schematic diagram of an aerosol generating product 100 according to an embodiment. In this embodiment, the aerosol generating product 100 is basically configured in a sheet-like or block-like shape. For example, in some optional embodiments, the aerosol generating product 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 in FIG. 1, the aerosol generating product 100 is configured in a square shape. Alternatively, in still some other alternative embodiments, the aerosol generating product 100 is configured in a shape such as a circle, an ellipse, a trapezoid, or a polygon.

[0101] In some specific embodiments, the aerosol generating product 100 has a length of approximately 5 to 10 cm, a width of approximately 5 to 20 mm, and a thickness of 1 to 3 mm.

[0102] In some embodiments, areal density of the aerosol generating product 100 is 100 to 600 g / m 2< .

[0103] In some embodiments, tensile strength of the aerosol generating product 100 is greater than 1.5 kN / m.

[0104] In some embodiments, the aerosol generating product 100 is bendable, foldable, or windable. Therefore, in use, an external force can be applied to bend or wind the aerosol generating product 100 into a required shape for use, for example, into a shape of a barrel.

[0105] In the embodiment in FIG. 1, the aerosol generating product 100 has a laminated structure, and is configured to include a plurality of layers formed by lamination. For example, in FIG. 1, the aerosol generating product 100 includes: a functional layer 110, an aerosol generating substrate 120 and a substrate layer 130 that are arranged in a stacked or laminated manner.

[0106] In an embodiment, the substrate layer 130 is thermally conductive. In a specific embodiment, for example, the substrate layer 130 includes a metallic or non-metallic material with suitable high thermal conductivity. In a specific embodiment, the thermal conductivity of the substrate layer 130 is at least 25 W / m·K, preferably at least 80 W / m·K; in a specific embodiment, the substrate layer 130 may include copper, iron, aluminum, tin, stainless steel, or an alloy including at least one thereof. In a preferred embodiment, the substrate layer 130 includes an aluminum foil layer. In use, the substrate layer 130 may be directly or indirectly heated, for example, by thermal conduction or electromagnetic induction, and then the aerosol generating substrate 120 is heated to generate aerosol.

[0107] In use, by being heated on one side of the substrate layer 130 by the heating apparatus 300, the aerosol generating product 100 releases aerosol from the other side facing away from the substrate layer 130.

[0108] In some embodiments, the substrate layer 130 has a thickness of approximately 0.001 to 0.2 mm. In a more preferred embodiment, the substrate layer 130 has a thickness of approximately 0.01 to 0.05 mm.

[0109] In some embodiments, the substrate layer 130 is rigid or hard.

[0110] In some preferred embodiments, a surface of the substrate layer 130 facing or bonded to the aerosol generating substrate 120 is non-smooth. For example, the surface of the substrate layer 130 facing or bonded to the aerosol generating substrate 120 is rough. For example, the surface of the substrate layer 130 made of metal or alloy foil is surface-processed by at least one process such as corona, electrochemical etching, indentation, or sandblasting, thereby forming a rough surface, for example, a sandblasted surface, on the surface of the substrate layer 130. The rough surface of the substrate layer 130 is beneficial for maintaining a close bond with the aerosol generating substrate 120 and for preventing relative movement between the substrate layer 130 and the aerosol generating substrate 120 in a bonding surface thereof.

[0111] In some embodiments, the aerosol generating substrate 120 may be used to mean a substrate that can release a volatile compound that may form aerosol. The aerosol may be generated by heating the aerosol generating substrate 120 to release the volatile compound. In some common embodiments, the aerosol generating substrate 120 is or may include a solid at room temperature.

[0112] In some embodiments, the aerosol generating substrate 120 may include one or more of powers, particles, fragments, strips or sheets of one or more of vanilla leaves, tobacco leaves, homogenized tobacco, and expanded tobacco. Alternatively, the solid aerosol generating substrate 120 may include an additional tobacco or non-tobacco volatile tobacco aroma compound that is released when the substrate is heated.

[0113] 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 a leaf, a bark, a fiber tissue, a stem, a root, a petal, a fruit, and the like of a plant. For example, in a specific embodiment, the active substrate includes or is derived from one or more plant varieties or components, derivatives or extracts thereof, and the plant variety is tobacco. For example, in a 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 one of the following: tobacco leaves, tobacco vein segments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast leaf tobacco, and expanded tobacco.

[0114] In some optional embodiments, the aerosol generating substrate 120 further includes: a flavorant. The flavorant may include a volatile flavor component. For example, in a common embodiment, the flavorant may provide a flavor selected from menthol, lemon, vanilla, orange, wintergreen, cherry, and cinnamon. The flavorant may include a volatile tobacco flavorant compound that is released from the aerosol generating substrate 120 upon heating.

[0115] In some optional embodiments, the aerosol generating substrate 120 further includes: an aerosol forming agent or a smoke producing agent. The aerosol forming agent or smoke producing agent contributes to formation of dense and stable aerosol in use. In some specific embodiments, the aerosol forming agent or smoke producing agent is or includes at least one of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and the like.

[0116] In some optional embodiments, the aerosol generating substrate 120 further includes: a binder.

[0117] In some optional embodiments, the aerosol generating substrate 120 further includes: reinforcing fibers. Fiber strength of the reinforcing fibers is generally higher than that of tobacco plants in the active substrate, thereby enhancing strength and plasticity of the aerosol generating substrate 120 in use. For example, in some specific embodiments, the reinforcing fibers include at least one of softwood fibers, hardwood fibers, hemp or flax fibers, bamboo fibers, and the like.

[0118] In a specific embodiment, the aerosol generating substrate 120 includes: 65 to 90 wt% of the active substrate, 3 to 10 wt% of the reinforcing fibers, 0 to 5 wt% of the binder, 5 to 15 wt% of the flavorant, and 10 to 20 wt% of the aerosol forming agent or smoke producing agent.

[0119] Alternatively, in a further specific embodiment, the aerosol generating substrate 120 includes: 65 to 90 wt% of the active substrate, 3 to 10 wt% of the reinforcing fibers, 0 to 5 wt% of the binder, 5 to 15 wt% of the flavorant, and 15 to 40 wt% of the aerosol forming agent or smoke producing agent.

[0120] In some embodiments, areal density of the aerosol generating substrate 120 is 20 to 150 g / m 2< .

[0121] In some embodiments, the aerosol generating substrate 120 has a thickness of 0.1 to 0.6 mm. Moreover, in some embodiments, the thickness of the aerosol generating substrate 120 is greater than that of the substrate layer 130 and / or the functional layer 110. Alternatively, the thickness of the aerosol generating substrate 120 exceeds half a thickness of the aerosol generating product 100.

[0122] In some embodiments, moisture content in the aerosol generating substrate 120 is 6 to 14 wt%.

[0123] In some embodiments, the aerosol generating substrate 120 may include a plurality of sub-layers. For example, in some optional embodiments, the aerosol generating substrate 120 may include a first sub-layer and a second sub-layer arranged in a laminated or stacked manner. The first sub-layer may include the active substrate, the reinforcing fibers, the aerosol forming agent or smoke producing agent, and the like. The second sub-layer mainly includes the flavorant. Then, in use, the first sub-layer is configured to generate aerosol, and the second sub-layer is configured to adjust or alter properties of the aerosol, such as taste or flavor.

[0124] Alternatively, in some other embodiments, the aerosol generating substrate 120 including a plurality of sub-layers may include a first sub-layer and a second sub-layer arranged in a laminated or stacked manner. The first sub-layer may include the active substrate such as tobacco. The second sub-layer includes the flavorant, and any one or more of functional additives such as a binder, a moisture-proof agent, a mildew-proof agent, and an antibacterial agent. For example, the second sub-layer includes 0 to 20 wt% of the flavorant, 80 to 100 wt% of the binder, 0 to 0.2 wt% of the moisture-proof agent, 0 to 0.5 wt% of the mildew-proof agent, and 0 to 0.5 wt% of the antibacterial agent.

The antibacterial agent may be a metal oxide or a metal ion inorganic antibacterial agent.

[0126] In some other embodiments, the second sub-layer of the aerosol generating substrate 120 has a thickness of 0.001 to 0.1 mm. During preparation, the second sub-layer is applied to the substrate layer 130 in a manner such as spraying, brushing, or film transfer. Subsequently, the first sub-layer is bonded to a surface of the second sub-layer by roll-pressing or casting, or the like, thereby forming a multi-sub-layer aerosol generating substrate 120.

[0127] Alternatively, in still some alternative embodiments, the aerosol generating substrate 120 may include a gel and / or a paste. The gel may be defined as an essentially diluted, crosslinked system, which does not exhibit flow when in a steady state. The paste may be defined as a viscous fluid, for example, paste-like or slurry-like. For example, the paste may be a fluid which, at rest, has a dynamic viscosity greater than 1 Pa·S or 5 Pa·S or 10 Pa·S.

[0128] In some embodiments, the functional layer 110 is dense. The functional layer 110 is configured to cover a surface of the aerosol generating substrate 120 facing away from the substrate layer 130.

[0129] In an embodiment, the functional layer 110 includes at least one of a polylactic acid film, a PE film, a PET film, a PVDC film, a food wrap, a metal foil, and paper. In an aspect, the functional layer 110 is configured to isolate the surface of the aerosol generating substrate 120 facing away from the substrate layer 130 from the outside air, so as to prevent oxidization or absorption of moisture of the aerosol generating substrate 120.

[0130] In an embodiment, for example, as shown in FIG. 2, a first identifier 111 that is identifiable is provided on the functional layer 110. As shown in FIG. 2, the first identifier 111 may be arranged as an identifiable pattern. Alternatively, in some other alternative embodiments, the first identifier 111 is an identifiable color, texture, number, text, QR code, or the like.

[0131] In some embodiments, the first identifier 111 is used to provide an identification indication related to a unique property of the aerosol generating product 100. The user or the heating apparatus identifies the first identifier 111 to acquire the unique property of the aerosol generating product 100.

[0132] In some embodiments, the unique property of the aerosol generating product 100 includes various information of the aerosol generating product 100, for example, authenticity information, expiration date, and a place of origin. In some embodiments, the above various information of the aerosol generating product 100 can be acquired by using the first identifier 111, so that it can be determined whether the aerosol generating product 100 is genuine, when the aerosol generating product 100 has expired, and where the aerosol generating product 100 was manufactured. Therefore, the user may not unintentionally use a non-genuine aerosol generating product 100, an expired aerosol generating product 100, or an aerosol generating product 100 from an undesirable source position.

[0133] In some other embodiments, the unique property of the aerosol generating product 100 may include flavor of the flavorant included in the aerosol generating substrate 120, such as peach, mint, or orange.

[0134] In another example, in some embodiments, the unique property of the aerosol generating product 100 may include strength of nicotine included in the aerosol generating substrate 120, such as nicotine content.

[0135] In another example, in some embodiments, the unique property of the aerosol generating product 100 may include an optimal heating temperature of the aerosol generating substrate 120.

[0136] In an embodiment, for example, as shown in FIG. 2, several or more second identifiers 112 that are identifiable are arranged at intervals on the functional layer 110. In some embodiments, the second identifier 112 is used to prompt or identify a position when the aerosol generating product 100 is packaged or received in the heating apparatus for heating. Alternatively, in some other embodiments, the second identifier 112 is used to provide identification of a heating position or a heating region of the aerosol generating product 100. For example, in FIG. 2, 4 second identifiers 112 are arranged at an interval along a length direction on the functional layer 110, to divide the aerosol generating product 100 into five unit portions 113 arranged along the length direction, so that the user or the apparatus aligns a heat source or a heating element respectively with the five unit portions 113 for heating. Alternatively, the second identifier 112 is used to prompt or identify information of a position at which the aerosol generating product 100 can be heated.

[0137] Alternatively, in some other alternative embodiments, the first identifier 111 and / or the second identifier 112 are / is formed on or bonded to the surface of the aerosol generating substrate 120.

[0138] In some embodiments, the functional layer 110 is flexible.

[0139] In some embodiments, the functional layer 110 may be torn off, separated from, or removed from the aerosol generating substrate 120 of the aerosol generating product 100.

[0140] In some embodiments, the functional layer 110 made of an organic polymer material, for example, a polylactic acid film, has a thickness of 3 to 20 µm. Alternatively, in some other optional embodiments, the functional layer 110 made of a paper material has a thickness of 0.1 to 0.5 cm.

[0141] In some embodiments, a temperature resistance range of the functional layer 110 is 150 to 350°C.

[0142] For example, FIG. 3 is a schematic diagram of preparation of the aerosol generating product 100 having a laminated structure according to an embodiment. As shown in FIG. 3, the preparation includes: S10: laying the substrate layer 130 flat on a conveyor belt 1a, and driving, by using a mobile device such as the conveyor belt 1a, the substrate layer 130 to be conveyed along a predetermined direction; where the conveyor belt 1a provides conveying power in a pulley-driven manner by rotating wheels; S20: making a raw material forming the aerosol generating substrate 120 into slurry, and casting the slurry onto a surface of the substrate layer 130 along a conveying direction of the substrate layer 130 by using a casting device 2a, so as to form the aerosol generating substrate 120 bonded to the substrate layer 130; and S30: pressing the functional layer 110 onto the surface of the aerosol generating substrate 120 in a roll-pressing manner by using a pressing roller 3a, to obtain the aerosol generating product 100.

[0143] For example, FIG. 4 is a schematic diagram of preparation of the aerosol generating product 100 having a laminated structure according to another embodiment. As shown in FIG. 4, the aerosol generating product 100 is prepared by using a multi-stage roll-pressing process. Specifically, the preparing by using multi-stage roll-pressing includes: S10a: first making a raw material forming the aerosol generating substrate 120 into a sheet-like aerosol generating substrate 120 by using a first pressing roller 1b through a roll-pressing process; S20a: laying the substrate layer 130 flat on a conveyor belt 2b downstream of the first pressing roller 1b, and driving, by using the conveyor belt 2b, the substrate layer 130 to be conveyed together in a moving direction of the aerosol generating substrate 120, so that the substrate layer 130 is conveyed in a same direction as the sheet-like aerosol generating substrate 120; where the conveyor belt 2b provides conveying power in a pulley-driven manner by rotating wheels; S30a: laminating, through a roll-pressing process by using a second pressing roller 3b, the aerosol generating substrate 120 and the substrate layer 130, which are conveyed in the same direction; and S40a: pressing, through a roll-pressing process by using a third pressing roller 4b, the functional layer 110 onto the surface of the aerosol generating substrate 120, to obtain the aerosol generating product 100.

[0144] FIG. 5 is a schematic diagram of an aerosol generating system according to an embodiment. As shown in FIG. 5, the aerosol generating system includes: an aerosol generating product 100; and a heating apparatus 300, configured to receive and heat the aerosol generating product 100, to generate aerosol for a user to inhale.

[0145] As shown in FIG. 5, the heating apparatus 300 includes: a rechargeable cell 310, configured to supply power. a circuit board 32, such as a PCB or an FPC board, provided with a circuit; a heating mechanism 330, enclosing or defining a receiving cavity 340; in use, the aerosol generating product 100 being capable of being received in the receiving cavity 340 by using an opening 380 in a surface of the heating apparatus 300 for heating or removal; and a suction nozzle 350, in fluid communication with the receiving cavity 340 to allow the user to puff on, by using the suction nozzle 350, the aerosol generated by the aerosol generating product 100.

[0146] As shown in FIG. 5, the heating mechanism 330 includes a plurality of or several heating elements 331; and the several heating elements 331 may be arranged on a same side of the receiving cavity 340; and when the aerosol generating product 100 is received in the receiving cavity 340, the several heating elements 331 all face or adjoin the substrate layer 130 of the aerosol generating product 100.

[0147] In some embodiments, when the aerosol generating product 100 is received in the receiving cavity 340, the several or plurality of heating elements 331 can directly or indirectly heat the substrate layer 130 of the aerosol generating product 100.

[0148] Alternatively, in some other embodiments, the several or plurality of heating elements 331 may be exposed to the receiving cavity 340. Further, when the aerosol generating product 100 is received in the receiving cavity 340, the several heating elements 331 are in contact with or abut against the substrate layer 130 of the aerosol generating product 100, so that heat generated by the heating elements 331 is conducted to the aerosol generating substrate 120 by using the substrate layer 130.

[0149] According to the embodiment shown in FIG. 5, the several or plurality of heating elements 331 are discretely arranged, which, for example, are arranged in an array in FIG. 5. Correspondingly, the aerosol generating substrate 120 of the aerosol generating product 100 includes several or a plurality of substrate units 121 fitting the heating elements 331. When the aerosol generating product 100 is received in the receiving cavity 340, the substrate units 121 can be heated by using the corresponding heating elements 331 to separately generate aerosol. For example, in FIG. 5, the continuously arranged substrate units 121 may be approximately rectangle-shaped.

[0150] In some embodiments, the several or plurality of heating elements 331 are arranged to be independently connected to the circuit board 320, so that the circuit board 320 independently supplies power, thereby independently performing heating. For example, in some embodiments, the several or plurality of heating elements 331 can be separately activated, so that each heating element 331 can separately heat only the corresponding substrate unit 121.

[0151] In some embodiments, the circuit board 320 is configured to control the several or plurality of heating elements 331 to be heated sequentially one after another in a predetermined order. In some embodiments, the circuit board 320 is configured to control the several or plurality of heating elements 331 not to be heated simultaneously. Therefore, for example, when the user puffs, the circuit board 320 controls only one heating element 331 to be heated to generate aerosol satisfying a single puff.

[0152] In some embodiments, in each puff, an amount of total particulate matter (TPM) generated by the substrate units of the aerosol generating product 100 when heated under independent control of the circuit board 320 over the several heating elements 331 may be 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.

[0153] In some embodiments, the circuit board 320 controls a predetermined order of the several heating elements 331, which are activated sequentially one after another. Specifically, for example, when the user performs a first puff, the circuit board 320 supplies power to a leftmost first heating element 331 for heating, to generate aerosol for a single puff. When the user performs a next puff, the circuit board 320 supplies power to a leftmost second heating element 331 for heating, to generate aerosol for a single puff. The process is performed in sequence, until after all the heating elements 331 are heated, the substrate units of the aerosol generating product 100 have been fully consumed, and the user is prompted to replace the aerosol generating product 100 with a new one. In the foregoing implementations, separately activating the heating elements 331 in sequence instead of simultaneously activating and heating means minimally avoiding excessive consumption of the aerosol generating substrate, and reducing energy waste. Alternatively, in some other implementations, the several heating elements 331 are sequentially activated in a predetermined order along an array arrangement direction.

[0154] Alternatively, in some other alternative implementations, the circuit board 320 controls the several heating elements 331 to be separately activated sequentially contiguously along an arrangement direction of the heating elements 331. Alternatively, in some other alternative implementations, the circuit board 320 controls the several heating elements 331 to be separately activated sequentially in an intermittent or skipping manner.

[0155] For example, in some embodiments, the several or plurality of heating elements 331 can be sequentially powered, that is, powered once per user puff, thereby generating aerosol consistently based on each puff. Correspondingly, in some embodiments, each user puffing action can be sensed by using an airflow sensor, for example, a microphone or a MEMS sensor. The circuit board 320 sequentially supplies power to the several or plurality of heating elements 331 based on a sensing result of the airflow sensor. In a preferred implementation, the circuit board 320 controls the several heating elements 331 to be sequentially activated in a predetermined order according to a puffing action of the user. Moreover, in some other alternative implementations, the circuit board 320 controls sequential activation of the several heating elements 331 according to a predetermined interval. For example, the predetermined interval ranges from about 30 s to 300 s.

[0156] For example, in some other embodiments, the circuit board 320 controls the several heating elements 331 to be sequentially activated in a predetermined order, based on an operation input signal on the foregoing heating apparatus 300. For example, the heating apparatus 300 is provided with an input element. The input element may include an input element such as a switch button, a touch screen, or a knob, which can be operated by the user to generate an input signal. The circuit board 320 controls, based on an operation input signal formed by the user operating the input element, the several heating elements 331 to be sequentially activated in a predetermined order.

[0157] In some embodiments, the circuit board 320 controls the several heating elements 331 to be sequentially activated in a predetermined order, based on removal or replacement of the aerosol generating product 100. Specifically, in some embodiments, after the circuit board 320 controls the foregoing heating elements 331 to be sequentially activated, the user is prompted that the aerosol generating product 100 has been fully consumed, and the user is prompted to replace the aerosol generating product 100 with a new one.

[0158] In addition, in some embodiments, after it is detected that a new aerosol generating product 100 is re-received in the receiving cavity 340 of the heating apparatus 300, the heating elements 331 are sequentially reactivated in a predetermined order. The detection that the user replaces the aerosol generating product 100 with a new one may be performed by using a sensor. For example, an optical sensor or a pressure sensor, or the like is provided in a vapor generation apparatus, and is configured to sense that the aerosol generating product 100 is bonded into the receiving cavity 340 or removed from the receiving cavity 340, and determine, according to the bonding and the removal, replacement or consumption of the aerosol generating product 100 by the user.

[0159] In some embodiments, the circuit board 320 controls the foregoing heating elements 331 to be sequentially activated in a cyclic manner. For example, in some embodiments, a cycle is performed according to a predetermined number of times, for example, 10 times. Specifically, when a number of times of activation of the heating elements 331, and / or a number of times of puffing by the user, and / or a number of times of receiving of an input signal inputted by the input element reaches a preset number of times, a new cycle is entered to control the heating elements 331 to be activated sequentially.

[0160] In another example, in some embodiments, the cycle is performed according to removal or replacement of the aerosol generating product 100.

[0161] In some embodiments, the circuit board 320 controls the several heating elements 331 to be heated according to a same heating curve or heating temperature. For example, in some specific embodiments, the circuit board 320 controls the heating elements 331 to be heated at a temperature of 300°C.

[0162] Alternatively, in some other alternative embodiments, the circuit board 320 controls the several heating elements 331 to be heated according to different heating curves or heating temperatures. For example, in some implementations, the circuit board 320 controls the heating temperature of the several heating elements 331 to sequentially increase or sequentially decrease along a heating activation order.

[0163] For example, in some embodiments, the circuit board 220 is configured to sequentially activate the several or plurality of heating elements 331, so that no two spatially adjacent heating elements 331 are continuously activated. Advantageously, this can minimize preheating of the heating element 331, which can reduce a possibility of thermal decomposition of a plurality of adjacent substrate units 121.

[0164] For example, in some embodiments, the circuit board 220 is configured to supply electric power to the heating elements 331 according to a given power sequence, so that the heating elements 331 reach an operating temperature within a predetermined time. For example, each time the circuit board 220 supplies power to the heating elements 331, the heating elements 331 are caused to reach a temperature of approximately at least 200 degrees, or at least 300 degrees, or at least 400 degrees within 0.5 s, and stop after maintaining the temperature for approximately 2.5 s.

[0165] In some embodiments, the aerosol generating product 100 may further include: one or more color-variable state identifiers 122 bonded to or arranged on one or more substrate units 121 of the aerosol generating substrate 120. The color-variable state identifier 122 can change a color in response to heating of the corresponding substrate unit 121, so as to provide a use state in which the substrate unit 121 is not heated or has been heated. Alternatively, the color-variable state identifier 122 has a variable color, so as to provide a color indication associated with a state of whether the substrate unit 121 is heated.

[0166] For example, in some embodiments, the color-variable state identifier 122 is a graphic or pattern formed on the surface of the substrate unit 121 by printing or stamping with color-changing ink. When the substrate unit 121 is heated, the color-variable state identifier 122 can change a color, for example, from gray to yellow, thereby indicating a state in which the substrate unit 121 has been heated and used. The color-changing ink may be directly purchased in some embodiments.

[0167] Alternatively, in some other alternative embodiments, a material of the aerosol generating substrate 120 and / or the substrate unit 121 include / includes the foregoing color-changing ink and the like. Further, the aerosol generating substrate 120 and / or the substrate unit 121 are / is configured to form a color change when heated, so as to prompt the user of a color indication associated with a state of whether the aerosol generating substrate 120 and / or the substrate unit 121 are / is heated. For example, in this embodiment, the color-changing ink is added, by blending or mixing, to a raw material of the aerosol generating substrate 120 and / or the substrate unit 121 during preparation, so that there is a heating-triggered color-changing state indication of whether the aerosol generating substrate 120 and / or the substrate unit 121 are / is heated.

[0168] In some embodiments, the several or plurality of heating elements 331 may be heated by using any suitable method. For example, at least one or all of the several or plurality of heating elements 331 may include an infrared heating element, or a magnetic field generator for induction heat, or a resistive heating element, or a combination thereof.

[0169] In some embodiments, the several or plurality of heating elements 331 are planar heating elements. In addition, in some embodiments, the several or plurality of heating elements 331 are configured to be heating elements that are stamped, printed, etched, deposited or electroplated. In addition, in some embodiments, the several or plurality of heating elements 331 are configured as patterned heating elements, for example, heating elements with meandering, serpentine or spiral geometric patterns.

[0170] In some embodiments, when at least one or all of the several or plurality of heating elements 331 include a resistive heating element, the resistive heating element preferably includes a resistive material. A suitable resistance material includes, but is not limited to, conductive ceramic, carbon, graphite, metal, a metal alloy, and a composite material made of a ceramic material and a metal material. This composite material may include doped ceramic or non-doped ceramic. A suitable example of the doped ceramic includes doped silicon carbide. A suitable example of the metal includes titanium, zirconium, tantalum, and platinum group metals. A suitable example of the metal alloy includes at least one of constantan, stainless steel, a nickel-containing alloy, a cobalt-containing alloy, a chromium-containing alloy, an aluminum-containing alloy, a titanium-containing alloy, a zirconium-containing alloy, a hafnium-containing alloy, a niobium-containing alloy, a molybdenum-containing alloy, a tantalum-containing alloy, a tungsten-containing alloy, a tin-containing alloy, a gallium-containing alloy, a manganese-containing alloy, an iron-containing alloy, and a nickel-iron-cobalt-stainless steel based superalloy.

[0171] In some embodiments, when at least one or all of the several or plurality of heating elements 331 include an induction heating element, the several or plurality of heating elements 331 may include a magnetic field generator for induction heating. By generating a magnetic field, the substrate layer 130 of the aerosol generating product 100 is induced to be penetrated by the magnetic field, so as to generate heat, which in turn heats the substrate unit 121 of the aerosol generating substrate 120. For example, the several or plurality of heating elements 331 may include an induction coil, for example, a planar spiral coil, to generate a magnetic field. In use, the circuit board 220 may supply an alternating current to the several or plurality of heating elements 331 of the induction coil, so as to induce the substrate layer 130 to generate heat when penetrated by the magnetic field, which in turn heats the substrate unit 121 of the aerosol generating substrate 120. Then, correspondingly, in this embodiment, the substrate layer 130 is a sensitive metal or alloy that can be penetrated by a magnetic field to generate heat, such as grade 430 stainless steel, Permalloy, or the like.

[0172] Alternatively, in some other embodiments, the several or plurality of heating elements 331 are optical heating elements, which, for example, heat the aerosol generating product 100 by emitting infrared light, lasers, or the like.

[0173] FIG. 6 is a schematic diagram of an aerosol generating product 100a suitable for optical heating according to another embodiment. In this embodiment, the aerosol generating product 100a having a laminated structure includes: an aerosol generating substrate 120a, a substrate layer 130a, and a light-absorbing layer 140a arranged in a stacked or laminated manner.

[0174] In an embodiment, the light-absorbing layer 140a may include a light-absorbing material. Alternatively, the light-absorbing layer 140a has reflectivity of less than 20% for heating light rays such as infrared light or lasers emitted by the heating elements 331, thereby allowing most heating light to be absorbed by the light-absorbing layer 140a and then converted into thermal energy. Alternatively, in a more preferred embodiment, the light-absorbing layer 140a has reflectivity of less than 10% for heating light rays such as infrared light or laser beams emitted by the heating elements 331.

[0175] In the embodiment shown in FIG. 6, the heating elements 331 emit heating light rays towards the light-absorbing layer 140a, as indicated by arrows R1. The light-absorbing layer 140a absorbs and converts the light rays into thermal energy, which in turn heats the substrate layer 130, thereby ultimately heating the aerosol generating substrate 120.

[0176] 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, carbon, or the like, which is advantageous for absorbing the heating light rays. Alternatively, the light-absorbing layer 140a is or includes a carbon layer or a graphite layer.

[0177] FIG. 7 and FIG. 8 are schematic diagrams of an aerosol generating product 100b according to another embodiment. In this embodiment, the aerosol generating product 100b having a multilayer structure includes: a substrate layer 130b, which is, for example, thermally conductive metal or alloy foil as described above, such as aluminum foil; a support layer 150b, bonded onto the substrate layer 130b; the support layer 150b being configured to enhance mechanical strength of the aerosol generating product 100b, thereby enabling the aerosol generating product 100b to exhibit greater rigidity, so as to reduce or prevent bending or deformation of the sheet-like aerosol generating product 100b; and an aerosol generating substrate 120b, configured to generate aerosol when heated; the aerosol generating substrate 120b being bonded onto the substrate layer 130b, and being enclosed by or step in the support layer 150b.

[0178] In some embodiments, a thickness of the support layer 150b is greater than that of the substrate layer 130b, so that the support layer 150b has higher mechanical strength. For example, the thickness of the support layer 150b is approximately 0.2 mm to 3 mm.

[0179] In some embodiments, the support layer 150b includes paper. Alternatively, the support layer 150b includes a fiber layer. The support layer 150b includes fiber paper made of wood fibers, hemp fibers or flax fibers, bamboo fibers, or the like.

[0180] As shown in FIG. 7 and FIG. 8, the substrate layer 130b is a continuous sheet or thin layer; and the support layer 150b is a mesh-like thin layer. The support layer 150b has several holes 151b that are discretely arranged. The aerosol generating substrate 120b is arranged to include substrate units discretely arranged in the holes 151b of the support layer 150b. In some embodiments, several discrete substrate units of the aerosol generating substrate 120b can be sequentially and independently heated, thereby generating aerosol.

[0181] As shown in FIG. 8, the several substrate units of the aerosol generating substrate 120b are substantially square-shaped. Alternatively, in some other alternative embodiments, the several substrate units of the aerosol generating substrate 120b may be configured in a shape such as a circle, a polygon, a triangle, a star, a semi-circle, a heart, a cross, or a water drop.

[0182] In some embodiments, surface areas of exposed surfaces of the substrate units of the aerosol generating substrate 120b are 4 mm 2< to 1000 mm 2< . In some embodiments, thicknesses of the substrate units of the aerosol generating substrate 120b range from 0.1 mm to 10 mm. In some embodiments, weights of the substrate units of the aerosol generating substrate 120b are 5 mg to 50 mg. In some embodiments, spacing distances between the substrate units of the aerosol generating substrate 120b that are adjacent to each other are 0.1 mm to 20 mm.

[0183] In some embodiments, thermal conductivity of the support layer 150b is less than 2 W / m·K, to provide thermal insulation between the discretely arranged substrate units of the aerosol generating substrate 120b. Through the thermal insulation of the support layer 150b, it is advantageous for 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 ranges from 0.03 W / m·K to 0.07 W / m·K.

[0184] Alternatively, in some other embodiments, the first identifier 111 and the second identifier 112 may be arranged or formed on a surface of the support layer 150b in a manner such as printing or spraying.

[0185] Alternatively, in some other embodiments, a color-variable state identifier 122 may further be formed or arranged on surfaces of the several discrete substrate units of the aerosol generating substrate 120b, to provide a color indication associated with a state of whether the substrate units are heated.

[0186] Alternatively, in some other embodiments, the aerosol generating product 100b may further include a tearable or removable functional layer, such as a polylactic acid film, a PE film, a PET film, and the like. The functional layer covers an exposed surface of the support layer 150b and / or the aerosol generating substrate 120b, to prevent moisture absorption by the aerosol generating substrate 120b and the like.

[0187] As shown in FIG. 7 and FIG. 8, the surfaces of the 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 compared 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 specifically, for example, the surface of the support layer 150b is 1 to 3 mm higher than the surface of the aerosol generating substrate 120b.

[0188] In some embodiments, a ratio of an area of the aerosol generating substrate 120b including the several substrate units to an area of the aerosol generating product 100b is 0.3:1 to 0.8:1.

[0189] In some embodiments, the weight 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 area of the exposed surface of each substrate unit of the aerosol generating substrate 120b is approximately 9 mm2 to 800 mm2.

[0190] FIG. 9 is a schematic diagram of a preparation method for the aerosol generating product 100b in FIG. 7 and FIG. 8 according to an embodiment. In this embodiment, the preparation of the aerosol generating product 100b includes: S10b: bonding, by adhesive bonding and pressing, the mesh-like support layer 150b with holes 151b to the surface of the substrate layer 130b in a laminated manner, as indicated by an arrow P2 in FIG. 9; and S20b: making a raw material of the aerosol generating substrate 120b into pourable slurry 1200b, injecting or pouring the pourable slurry 1200b into the holes 151b of the support layer 150b by using an injection device 20b, such as an injector, and then performing drying and curing, to obtain the aerosol generating product 100b shown in FIG. 7 and FIG. 8.

[0191] In some embodiments, the aerosol generating product 100b prepared by injection or pouring of the pourable slurry 1200b approximately has a length of 3 cm to 10 cmm, a width of 1.2 cm to 8 cm, and a thickness of approximately 0.8 to 3 mm.

[0192] Alternatively, FIG. 10 is a schematic diagram of an aerosol generating product 100c according to another alternative embodiment. In this embodiment, the aerosol generating product 100c includes: a mesh-like support layer 150c, having several holes 151c; a thermally conductive substrate layer 130c, discretely arranged in the holes 151c of the support layer 150c; and an aerosol generating substrate 120c, including several substrate units discretely arranged in the holes 151c of the support layer 150c, and the substrate units being bonded onto the substrate layer 130c. In use, the substrate units of the aerosol generating substrate 120c can receive heat relative to the substrate layer 130c and be heated. In addition, thermal insulation between several or adjacent substrate units of the aerosol generating substrate 120c is provided by the support layer 150c. In addition, the substrate units of the aerosol generating substrate 120c and the substrate layer 130c are supported or retained by the support layer 150c.

[0193] In the aerosol generating product 100c in this embodiment, the substrate layer 130c is embedded into or located in the holes 151c of the support layer 150c. Alternatively, in some other embodiments, the support layer 150c is inserted into or embedded into the substrate layer 130c.

[0194] Alternatively, FIG. 11 is a schematic diagram of an aerosol generating product 100d according to another alternative embodiment. In this embodiment, the aerosol generating product 100d includes: a thermally conductive substrate layer 130d, which is, for example, made of the metal or alloy described above; a side surface of the substrate layer 130d being provided with several blind holes 131d discretely arranged; and an aerosol generating substrate 120d, including several substrate units discretely arranged in the blind holes 131d of the substrate layer 130d, and the substrate units being bonded onto the substrate layer 130d. In use, the substrate units of the aerosol generating substrate 120d can receive heat relative to the substrate layer 130d and be heated.

[0195] In the aerosol generating product 100d in this embodiment, the substrate units of the aerosol generating substrate 120d are respectively accommodated and retained in the blind holes 131d of the substrate layer 130d to be supported and respectively heated.

[0196] Alternatively, FIG. 12 is a schematic diagram of an aerosol generating product 100e according to another alternative embodiment. In this embodiment, the aerosol generating product 100e having a multilayer structure includes: a thermally conductive substrate layer 130e, which is, for example, made of the metal or alloy described above; an aerosol generating substrate 120e, formed on or bonded onto the substrate layer 130e; and a mesh-like support layer 150e, having several holes 151e discretely and equally arranged. The support layer 150e is bonded to the aerosol generating substrate 120e in a manner such as roll-pressing. By roll-pressing or pressing or the like, part of the support layer 150e is embedded into the aerosol generating substrate 120d from the surface of the aerosol generating substrate 120e. Moreover, at least part of the aerosol generating substrate 120e is embedded into the holes 151e of the support layer 150e, thereby defining substrate units located in the holes 151e.

[0197] Specifically, as shown in FIG. 12, the aerosol generating substrate 120e includes: a first portion 1210e, including a plurality of substrate units discretely located in the holes 151e of the support layer 150e; and a second portion 1220e, located between the support layer 150e and the substrate layer 130e; and configured to provide bonding between the support layer 150e and the substrate layer 130e.

[0198] Another embodiment of this application further provides an aerosol generating system. For example, as shown in FIG. 13 and FIG. 14, the aerosol generating system includes: an aerosol generating product 100f; and a heating apparatus 300f, configured to receive and heat the aerosol generating product 100f, to generate aerosol for a user to inhale. The heating apparatus 300f includes: a receiving cavity 340f, configured to receive the aerosol generating product 100f; and a heating mechanism 330f, at least partially enclosing or defining or adjoining the receiving cavity 340f. In use, the aerosol generating product 100f can be received in the receiving cavity 340f by using an opening 380f in a surface of the heating apparatus 300f for heating, as shown by an arrow P3 in FIG. 13.

[0199] According to the embodiments shown in FIG. 13 and FIG. 14, the aerosol generating product 100f basically has a multi-layer structure, and includes: a substrate layer 130f, a support layer 150f and an aerosol generating substrate 120f arranged in a laminated or stacked manner. The aerosol generating substrate 120f includes a plurality of substrate units discretely arranged. The support layer 150f is basically in a mesh shape, so as to enclose and separate the substrate units of the aerosol generating substrate 120f.

[0200] As shown in FIG. 13 and FIG. 14, the aerosol generating product 100f further includes: a retaining region 152f, configured such that when the aerosol generating product 100f is received in the receiving cavity 340f of the heating apparatus 300f, the heating apparatus 300f stably holds the aerosol generating product 100f in the receiving cavity 340f by clamping or abutting against the retaining region 152f. The substrate units of the aerosol generating substrate 120f avoid the retaining region 152f, or the substrate units of the aerosol generating substrate 120f do not exist in the retaining region 152f.

[0201] In the embodiments shown in FIG. 13 and FIG. 14, the retaining region 152f may be indicated or defined by a connecting structure arranged on the aerosol generating product 100f. For example, in FIG. 12 and FIG. 13, the retaining region 152f is provided with a connecting structure that may be connected to a retaining structure 341f on the heating apparatus 300f, thereby retaining the aerosol generating product 100f by forming a connection with the retaining structure 341f. For example, in some embodiments, the retaining structure 341f on the heating apparatus 300f is, for example, an extruded protrusion or a clamping rod. Correspondingly, the retaining region 152f is provided with a fitting indent or hole, or the like, to form a fit. Alternatively, in some other alternative embodiments, the retaining region 152f is formed or defined on the support layer 150f. Moreover, the retaining region 152f is arranged to have a color different from that of another part of the support layer 150f, so as to be identified or operated by the user.

[0202] As shown in FIG. 13 and FIG. 14, the retaining region 152f is close to two sides of the aerosol generating product 100f in a length direction. For example, the retaining region 152f includes a first retaining region arranged close to a first end of aerosol generating product 100f in the length direction, and a second retaining region arranged close to a second end of the aerosol generating product 100f in the length direction. Moreover, the several discrete substrate units of the aerosol generating substrate 120f are located between the first retaining region and the second retaining region.

[0203] Correspondingly, the retaining structure 341f on the heating apparatus 300f includes a first retaining structure arranged close to a first end of the receiving cavity 340f in the length direction and a second retaining structure arranged close to a second end of the receiving cavity 340f in the length direction.

[0204] In some embodiments, the retaining structure 341f is arranged facing away from the heating mechanism 330f in the receiving cavity 340f, so that the retaining structure 341f can extrude or fix the aerosol generating product 100f towards the heating mechanism 330f. In this way, the aerosol generating product 100f, mainly the substrate layer 130f, maintains contact with or conducts heat from the heating mechanism 330f.

[0205] As shown in FIG. 13 and FIG. 14, the heating mechanism 330f of the heating apparatus 300f further includes: a plurality of or several heating elements 331f. Moreover, the several heating elements 331f may be arranged on a same side of the receiving cavity 340f. In addition, when the aerosol generating product 100f is received in the receiving cavity 340f, the several heating elements 331f all face or adjoin the substrate layer 130f of the aerosol generating product 100f. Moreover, when the aerosol generating product 100f is received in the receiving cavity 340f, the several heating elements 331f are respectively aligned with the substrate units of the aerosol generating substrate 120f. Therefore, in use, the substrate units of the aerosol generating substrate 120f can be independently heated by the relative heating elements 331f.

[0206] Alternatively, in some embodiments, the several heating elements 331f are configured to be sequentially activated and heated one by one, thereby sequentially heating the substrate units of the aerosol generating substrate 120f one by one to generate aerosol.

[0207] Alternatively, in this embodiment, the aerosol generating product 100f further includes: one or more color-variable state identifiers, to be used to provide a color indication associated with a state of whether the substrate units of the aerosol generating substrate 120f are heated. In this embodiment, the one or more color-variable state identifiers are a color-variable pattern or an identifiable mark or the like that is formed on or bonded to the substrate units of the aerosol generating substrate 120f, so as to change a color in response to the heating of the substrate units of the corresponding aerosol generating substrate 120f, to provide a use state in which the substrate units of the aerosol generating substrate 120f are heated or have been heated. For example, in some embodiments, the color-variable state identifier is a graphic or pattern formed on the surface of the substrate unit by printing or stamping with color-changing ink. When the substrate unit is heated, the color-variable state identifier can change a color, for example, from gray to yellow, thereby indicating a use state in which the substrate unit has been heated.

[0208] FIG. 15 is a schematic diagram of an aerosol generating system according to an embodiment. In this embodiment, the aerosol generating system includes: an aerosol generating product 100g; and a heating apparatus 300g, configured to receive and heat the aerosol generating product 100g, to generate aerosol for a user to inhale.

[0209] As shown in FIG. 15, the aerosol generating product 100g includes: an operating portion 1100g and an aerosol generating portion 1200g. The operating portion 1100g and the aerosol generating portion 1200g are sequentially arranged along a width direction of the aerosol generating product 100g.

[0210] The aerosol generating portion 1200g is mainly configured to be received into a receiving cavity 340g of the heating apparatus 300g for heating to generate aerosol.

[0211] The operating portion 1100g is operated by the user, for example, by being gripped with fingers, so that the aerosol generating portion 1200g is received into the receiving cavity 340g or removed from the receiving cavity 340g. In addition, in use, the operating portion 1100g is not received inside the receiving cavity 340g of the heating apparatus 300g, or the operating portion 1100g is exposed outside the receiving cavity 340g of the heating apparatus 300g.

[0212] As shown in FIG. 15, for a sheet-like aerosol generating product 100g, a thickness of the operating portion 1100g is greater than that of the aerosol generating portion 1200g.

[0213] As shown in FIG. 15, the aerosol generating substrate 120g of the aerosol generating product 100g is arranged to be located in the aerosol generating portion 1200g and avoid the operating portion 1100g. Moreover, a retaining region 152g of the aerosol generating product 100g may be located on the aerosol generating portion 1200g and avoid the operating portion 1100g.

[0214] As shown in FIG. 15, a substrate layer 130g of the aerosol generating product 100g extends from the operating portion 1100g to the aerosol generating portion 1200g. Similarly, the support layer 150g of the aerosol generating product 100g extends from the operating portion 1100g to the aerosol generating portion 1200g.

[0215] As shown in FIG. 15, the receiving cavity 340g has a first side wall 3410g close to or adjacent to a heating mechanism 330g and / or a heating element 331g, and a second side wall 3420g facing away from the heating mechanism 330g and / or the heating element 331g. When the aerosol generating product 100g is received in the receiving cavity 340g, the aerosol generating product 100g abuts against or fits with the first side wall 3410g of the receiving cavity 340g. Moreover, there is a gap between the aerosol generating product 100g and the second side wall 3420g of the receiving cavity 340g, and the gap therebetween defines at least part of an aerosol output channel for outputting the aerosol generated by heating the aerosol generating substrate 120g.

[0216] FIG. 16 illustrates an aerosol generating system according to another embodiment. In this embodiment, the aerosol generating system includes: an aerosol generating product 100h, and a heating apparatus 300h.

[0217] The aerosol generating product 100h includes an operating portion 1100h and an aerosol generating portion 1200h. The aerosol generating portion 1200h is mainly configured to be received into a receiving cavity 340h of the heating apparatus 300h for heating to generate aerosol. The operating portion 1100h is operated by the user, for example, by being gripped with fingers, so that the aerosol generating portion 1200h is received into the receiving cavity 340h of the heating apparatus 300h or removed from the receiving cavity 340h of the heating apparatus 300h. In addition, in use, the operating portion 1100h is not received inside the receiving cavity 340h of the heating apparatus 300h, or the operating portion 1100h is exposed outside the receiving cavity 340h of the heating apparatus 300h.

[0218] The heating apparatus 300h includes: a heating mechanism 330h, adjoining or at least partially defining the receiving cavity 340h; the heating mechanism 330h including several or a plurality of heating elements 331h arranged along a longitudinal direction of the receiving cavity 30h, to heat the aerosol generating portion 1200h of the aerosol generating product 100h received in the receiving cavity 340h, to generate aerosol; an air inlet 360h, in airflow communication with the receiving cavity 340h, thereby allowing air to enter the receiving cavity 340h during puffing; and a suction nozzle 350h, in fluid communication with the receiving cavity 340h to allow the user to puff on, by using the suction nozzle 350h, the aerosol generated by the aerosol generating product 100h.

[0219] As shown in FIG. 16 to FIG. 18, the aerosol generating product 100h has a laminated structure or a multilayer structure. In addition, the aerosol generating product 100h includes: a thermally conductive substrate layer 130h, a support layer 150h, and an aerosol generating substrate 120h.

[0220] In this embodiment, the support layer 150h is provided with several holes 151h discretely arranged. The aerosol generating substrate 120h includes a plurality of substrate units discretely arranged in the holes 151h.

[0221] In the embodiments shown in FIG. 16 to FIG. 18, gaps exist between the substrate units of the aerosol generating substrate 120h and inner side walls of the holes 151h, for example, a gap d1 and a gap d2 shown in FIG. 18. The gap d1 and / or the gap d2 are / is approximately 1 to 2 mm. Further, gap spaces 153h exist between the substrate units of the aerosol generating substrate 120h and the inner side walls of the holes 151h, and the gap spaces 153h are approximately annular, surrounding the substrate units of the aerosol generating substrate 120h. In use, the aerosol generated by heating the substrate units of the aerosol generating substrate 120h is released into the gap spaces 153h, and then is delivered to the suction nozzle 350h with inhalation airflow, to be puffed on by the user.

[0222] As shown in FIG. 16 to FIG. 18, the aerosol generating product 100h includes a first side 11h and a second side 12h opposite each other along a width direction. The operating portion 1100h is close to or defines the first side 11h, and the aerosol generating portion 1200h is close to or defines the second side 12h. Moreover, the aerosol generating substrate 120h is located on the aerosol generating portion 1200h, and is relatively closer to the second side 12h. In addition, as shown in FIG. 16 to FIG. 18, the gap spaces 153h surrounding the substrate units of the aerosol generating substrate 120h are open on the second side 12h, so as to output the aerosol. For example, as shown by an arrow R2 in FIG. 18, the aerosol in the gap spaces 153h exit from the second side 12h, and is then delivered to the suction nozzle 350h with the airflow.

[0223] Alternatively, in some embodiments, the heating apparatus 300h further includes an airflow channel, which defines an airflow path from an air inlet 360h to the suction nozzle 350h through the receiving cavity 340h, so as to deliver the aerosol to the suction nozzle 350h. In some embodiments, when the aerosol generating product 100h is received in the receiving cavity 340h and is heated to generate aerosol, the airflow channel of the heating apparatus 300h flows at least partially through the second side 12h of the gap spaces 153h. Alternatively, in some embodiments, when the aerosol generating product 100h is received in the receiving cavity 340h and is heated to generate aerosol, the gap spaces 153h are in fluid communication with the airflow channel of the heating apparatus 300h.

[0224] In some embodiments, the gap spaces 153h are further configured to provide thermal insulation outside the substrate units of the aerosol generating substrate 120h, so as to prevent transfer of heat from the substrate units of the aerosol generating substrate 120h to other adjacent substrate units.

[0225] As shown in FIG. 16 to FIG. 18, a plurality of or several gap spaces 153h surrounding the substrate units of the aerosol generating substrate 120h are separated from each other and are not connected to each other.

[0226] Alternatively, FIG. 19 is a schematic diagram of an aerosol generating product 100j according to another alternative embodiment. In this embodiment, the aerosol generating product 100j includes: a substrate layer 130j; a support layer 150j, bonded onto the substrate layer 130j, and provided with several holes 151j discretely arranged; and an aerosol generating substrate 120j, including several or a plurality of substrate units arranged in the holes 151j, and capable of being heated by the substrate layer 130j to generate aerosol.

[0227] The aerosol generating product 100j further includes: gap spaces 153j surrounding the substrate units of the aerosol generating substrate 120j, to provide thermal insulation. Alternatively, the gap spaces 153j are used to accommodate the aerosol generated by heating the substrate units of the aerosol generating substrate 120j. The gap spaces 153j are defined between inner side walls of the holes 151j of the support layer 150j and the substrate units.

[0228] The aerosol generating product 100j further includes: an aerosol output channel 154j, communicated with the gap spaces 153j, to output the aerosol in the gap spaces 153j to the outside of the aerosol generating product 100j or the suction nozzle 350h of the heating apparatus 300h.

[0229] In this embodiment, the several or plurality of gap spaces 153j are in communication with each other by using the aerosol output channel 154j.

[0230] Alternatively, in some other alternative embodiments, a plurality of, for example, two, three, or more, aerosol output channels 154j may be provided. For example, FIG. 20 illustrates that in still another embodiment, a plurality of gap spaces 153k defined between the support layer 150k of the aerosol generating product 100k and the substrate units of the aerosol generating substrate 120k are communicated with each other by using two output channels 154k and output the aerosol.

[0231] Alternatively, FIG. 21 is a schematic diagram of a plurality of gap spaces 153m on a support layer 150m of an aerosol generating product 100m in still another alternative embodiment, which are respectively arranged on two sides of an aerosol output channel 154m, and are communicated to output aerosol.

[0232] Alternatively, in still another embodiment shown in FIG. 22, a plurality of gap spaces 153n on a support layer 150n of an aerosol generating product 100n solely output aerosol through respective connected aerosol output channels 154n, avoiding other gap spaces 153n.

[0233] In the foregoing embodiments, the aerosol output channel 154j / 154k / 154m / 154n is configured to extend flat; and width dimensions of the aerosol output channel 154j / 154k / 154m / 154n are substantially constant; and the aerosol output channel 154j / 154k / 154m / 154n is arranged to extend along a length or width direction of the aerosol generating product 100j / 100k / 100m / 100n. In still other alternative embodiments, the aerosol output channel 154j / 154k / 154m / 154n may be arranged to extend in a curved, bent or meandering manner, or may be arranged to extend, for example, in a sinusoidal, polyline, or curved manner; and the width dimensions of the aerosol output channel 154j / 154k / 154m / 154n are variable, which may, for example, at least partially increase or decrease.

[0234] Alternatively, FIG. 23 to FIG. 25 are schematic diagrams of an aerosol generating product 100p according to another alternative embodiment. In this embodiment, the aerosol generating product 100p having a multilayer structure includes: a substrate layer 130p; an aerosol generating substrate 120p, bonded onto the substrate layer 130p; and a support layer 150p, including a plurality of discrete support units. Each support unit is approximately in a shape of a frame having a central hole 151p. Each support unit of the support layer 150p is bonded to the aerosol generating substrate 120p in a pressing manner such as roll-pressing, and is at least partially embedded into the aerosol generating substrate 120p, as shown by arrows P3 in FIG. 23.

[0235] In the aerosol generating product 100p formed after lamination, the aerosol generating substrate 120p into which the support layer 150p is embedded includes: several substrate units 121p located in the holes 151p of the support units of the support layer 150p; and bare units 122p located between the support units of the support layer 150p. In use, both the substrate units 121p and the bare units 122p of the aerosol generating substrate 120p can be heated by the substrate layer 130p to generate aerosol. The aerosol generated by heating the substrate units 121p escapes directly from the surface and is then released from the holes 151p of the support units of the support layer 150p. The bare units 122p are released from between the support units of the support layer 150p by the generated aerosol.

[0236] FIG. 26 to FIG. 27 are schematic diagrams of an aerosol generating product 100q according to another alternative embodiment. In this embodiment, the aerosol generating product 100q is in an elongated sheet-like shape; and the aerosol generating product 100q includes: an operating portion 1100q and an aerosol generating portion 1200q sequentially arranged along a length direction. The aerosol generating portion 1200q is provided with an aerosol generating substrate 120q. The aerosol generating substrate 120q may include a plurality of discrete substrate units bonded onto the substrate layer 130q, thereby being heated by receiving heat from the substrate layer 130q to generate aerosol. The operating portion 1100q is configured to be gripped by fingers of a user to perform an operation, thereby receiving the aerosol generating product 100q in the receiving cavity 340q of the heating apparatus 300q for heating or removal.

[0237] As shown in FIG. 26 and FIG. 27, the aerosol generating product 100q further includes: a detectable identification element 160q, arranged to be located in the operating portion 1100q. The detectable identification element 160q may be a pattern, a graphic, a color, a QR code, or an identifiable mechanical structure, an electronic device, or the like arranged on the operating portion 1100q.

[0238] In some specific embodiments, the detectable identification element 160q may be a transparent pattern or coating that is printed or sprayed.

[0239] FIG. 28 and FIG. 29 are schematic diagrams of a heating apparatus 300q correspondingly fitting an aerosol generating product 100q. As shown in FIG. 28 and FIG. 29, the heating apparatus 300q includes: a receiving cavity 340q, configured to receive an aerosol generating portion 1200q of the aerosol generating product 100q; and a detection unit 370q, which is a detection device such as an optical sensor, a camera, or a color sensor. The detection unit 370q may be arranged close to an opening of a surface of the heating apparatus 300q, to detect the detectable identification element 160q of the aerosol generating product 100q, thereby determining that the aerosol generating product 100q is accurately received in the receiving cavity 340q or removed from the receiving cavity 340q.

[0240] In some specific embodiments, the detection unit 370q is a camera, which determines that the aerosol generating product 100q is accurately received in the receiving cavity 340q by identifying the detectable identification element 160q of a transparent pattern or coating.

[0241] As shown in FIG. 26 to FIG. 29, a receiving position indication 170q is arranged on a surface of the aerosol generating product 100q, for example, on the detectable identification element 160q. For example, in this embodiment, the receiving position indication 170q is used to prompt a visual indication to the user that the aerosol generating product 100q is correctly received in the receiving cavity 340q of the heating apparatus 300q. For example, in this embodiment, the receiving position indication 170q is an indication line that is formed by printing or stamping or the like. The indication line is substantially flush with an opening or a surface of the heating apparatus 300q when the aerosol generating product 100q is correctly received in the receiving cavity 340q of the heating apparatus 300q. Therefore, the user may determine, by viewing that the indication line is flush with the opening or the surface of the heating apparatus 300q, that the aerosol generating product 100q is correctly received in the receiving cavity 340q of the heating apparatus 300q.

[0242] For example, as shown in FIG. 28, when the user grips the operating portion 1100q of the aerosol generating product 100q by using fingers, to receive the aerosol generating portion 1200q in the receiving cavity 340q of the heating apparatus 300q in an operation direction shown by an arrow P4 in FIG. 28, the detection unit 370q detects existence of the detectable identification element 160q, thereby determining that the aerosol generating portion 1200q has been correctly received in the receiving cavity 340q of the heating apparatus 300q.

[0243] Correspondingly, the heating apparatus 300q is configured to: allow, when the detection unit 370q detects the existence of the detectable identification element 160q, supply of power to heating elements to heat the aerosol generating portion 1200q to generate aerosol; and prevent, when the detection unit 370q detects absence of the detectable identification element 160q, supply of power to the heating elements.

[0244] In the embodiments shown in FIG. 26 to FIG. 29, the operating portion 1100q of the aerosol generating product 100q is formed by extending the substrate layer 130q and the support layer 150q from the aerosol generating portion 1200q. Consequently, during preparation, there is a need to only reserve the substrate layer 130q and the support layer 150q to be sufficiently longer, with part thereof defining the operating portion 1100q.

[0245] In the embodiments shown in FIG. 26 to FIG. 29, the aerosol generating product 100q substantially sheet-like or block-like is asymmetric in at least one of a length direction and a width direction, which is advantageous for the user to identify a direction or provide fool proofing. For example, in the embodiments shown in FIG. 26 to FIG. 29, a left end of the aerosol generating product 100q along the length direction is a straight edge, and the left end along the length direction is an arc-shaped edge. As a result, the aerosol generating product 100q is asymmetric along the length direction.

[0246] Alternatively, FIG. 30 is a schematic diagram of an aerosol generating product 100r according to another alternative embodiment. In this embodiment, the aerosol generating product 100r includes: an operating portion 1100r and an aerosol generating portion 1200r. In this embodiment, the operating portion 1100r and the aerosol generating portion 1200r are respectively prepared and then bonded or mechanically connected to form a secure connection.

[0247] For example, in the embodiment shown in FIG. 30, the aerosol generating portion 1200r includes: a substrate layer 130r, a support layer 150r and an aerosol generating substrate 120r, which are obtained by the processes such as roll-pressing and pouring described above. The operating portion 1100r includes a detectable identification element 160r and a substrate 170r. For example, the substrate 170r is made of a material such as independent organic polymer plastic or metal, and the identification element 160r is a detectable pattern or coating or QR code or the like in an identifiable color that is formed on or bonded to the substrate 170r.

Therefore, in use, it is convenient for the user to identify positive and negative directions of the thickness direction of the aerosol generating portion 1200r by using a thickness difference between the two portions. For example, in the embodiment shown in FIG. 30, the user can determine an upper surface of the aerosol generating product 100r since an upper surface of the operating portion 1100r protrudes more in the thickness direction.

[0249] In some embodiments, the heating apparatus 300q has such an opening dimension that the aerosol generating portion 1200r of the aerosol generating product 100r can be inserted into or received in the receiving cavity 340q through the opening, and prevent the operating portion 1100r from being inserted into or received in the receiving cavity 340q through the opening.

[0250] Alternatively, FIG. 31 is a schematic diagram of an aerosol generating product 100s substantially sheet-like or block-like according to still another alternative embodiment. In this embodiment, a left end of a substrate layer 130s of an aerosol generating product 100s in a length direction protrudes more than the support layer 150s and / or the aerosol generating substrate 120s, so that the aerosol generating product 100s forms an asymmetry along the length direction, which is beneficial for the user to identify a direction or provide fool proofing.

Moreover, correspondingly, the receiving cavity of the heating apparatus may have a circular shape, so as to enable the aerosol generating portion 1200t to rotate around the virtual center O in the receiving cavity. In addition, correspondingly, the heating apparatus further includes a detection unit, for example, a detection device such as an optical sensor, a camera, or a color sensor, to detect the detectable identification element 160t of the operating portion 1100t, thereby determining that the aerosol generating portion 1200t is accurately received in the receiving cavity. For example, when the aerosol generating portion 1200t rotates to a position where the detection unit can detect the detectable identification element 160t on the operating portion 1100t, a prompt, such as vibration or light, is issued to prompt the user that the aerosol generating portion 1200t is accurately received in the receiving cavity.
