Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of heat-not-burn aerosol generation, and in particular to an aerosol generating product, a preparation method and an aerosol generating system. Background Art

[0002] Smoking products (e.g., cigarettes, cigars, etc.) burn tobacco to produce tobacco smoke during use. People try to replace these tobacco-burning products by making products that release compounds without burning. Examples of such products are heating devices that release compounds by heating rather than burning materials. 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 the aerosol-generating substrate to a heating element for heating by transmitting a tape-like aerosol-generating substrate; such a heating device transmits and heats the tape-like aerosol-generating substrate to allow a consistent aerosol delivery amount to be accurately provided to consumers each time.

[0162] 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.

[0163] For example Figure 1A schematic diagram of an aerosol generating article 100 of an embodiment is shown; in this embodiment, the aerosol generating article 100 is basically configured to be in the shape of a sheet or a block. For example, in some optional embodiments, the aerosol generating article 100 has a length of about 1 to 100 cm, a width of 2 to 30 mm, and a thickness of about 0.1 to 6 mm. Figure 1 In some embodiments, the aerosol generating article 100 is configured to be square in shape; or in some other variations, the aerosol generating article 100 is configured to be circular, elliptical, trapezoidal, polygonal, etc.

[0164] 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.

[0165] In some embodiments, the aerosol-generating article 100 has an area density of 100 to 600 g / m 2 .

[0166] In some embodiments, the tensile strength of the aerosol-generating article 100 is greater than 1.5 kN / m.

[0167] In some embodiments, the aerosol generating article 100 can be bent or 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.

[0168] exist Figure 1 In the embodiment of the invention, the aerosol generating article 100 has a laminate structure and is constructed to include a plurality of layers formed by lamination. Figure 1 In the invention, the aerosol generating article 100 comprises:

[0169] The functional layer 110 , the aerosol generating substrate 120 , and the base layer 130 are arranged in a stacked or laminated manner.

[0188] Or in some other 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; the second sublayer may include flavors, and any one or more of functional additives such as adhesives, moisture-proofing agents, mildew-proofing agents, and antibacterial agents.

[0191] Alternatively, in yet other variations, the aerosol-generating substrate 120 may include a gel and / or a paste. A gel may be defined as a substantially dilute cross-linked system that does not exhibit flow when 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 has a dynamic viscosity greater than 1 Pa·S, 5 Pa·S, or 10 Pa·S when at rest.

[0192] 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 .

[0193] In one 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 preservative film, 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 away from the base layer 130 from the outside air to prevent the aerosol generating substrate 120 from being oxidized or hygroscopic.

[0194] In one embodiment, for example Figure 2 In the figure, a first identifiable mark 111 is arranged on the functional layer 110; Figure 2 As shown, the first identification 111 may be arranged into a recognizable pattern; or in some other variations, the first identification 111 is a recognizable color, pattern, number, text, QR code, etc.

[0195] In some embodiments, the first mark 111 is used to provide an identification indication related to the unique property of the aerosol-generating article 100. A user or a heating device obtains the unique property of the aerosol-generating article 100 by identifying the first mark 111.

[0196] In some embodiments, the unique properties of the aerosol-generating article 100 include various information of the aerosol-generating article 100, such as authenticity information, expiration date, and place of origin. In some embodiments, the various information of the aerosol-generating article 100 can be obtained through the first identifier 111, so that it can be determined whether the aerosol-generating article 100 is authentic, or when the aerosol-generating article 100 has expired and where the aerosol-generating article 100 was manufactured. Therefore, the user may not accidentally use an inauthentic aerosol-generating article 100, an expired aerosol-generating article 100, or an aerosol-generating article 100 from an unexpected source location.

[0197] In yet other embodiments, the unique properties of the aerosol-generating article 100 may include the taste of a flavorant contained in the aerosol-generating substrate 120 , such as peach flavor, mint flavor, or orange flavor.

[0198] As another example, in some embodiments, the unique properties of the aerosol-generating article 100 may include the strength of nicotine contained in the aerosol-generating substrate 120, such as the nicotine content.

[0199] 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 .

[0200] In one embodiment, for example Figure 2 In the figure, several or more identifiable second marks 112 are arranged at intervals on the functional layer 110; in some embodiments, the second marks 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. Or in some other embodiments, the second marks 112 are used to provide identification of the heating position or heating area of ​​the aerosol generating article 100; for example, Figure 2 In the embodiment, four second marks 112 are arranged at intervals along the length direction on the functional layer 110 to divide the aerosol generating article 100 into five unit parts 113 arranged along the length direction, so that the user or the device heats the five unit parts 113 by respectively aligning the heat source or the heating element. Alternatively, the second marks 112 are used to indicate or identify the position information of the aerosol generating article 100 that can be heated.

[0201] Or in some alternative embodiments, the first mark 111 and / or the second mark 112 is formed on or combined with the surface of the aerosol generating substrate 120 .

[0202] In some embodiments, the functional layer 110 is flexible.

[0203] In some embodiments, the functional layer 110 may be torn off or otherwise separated or removed from the aerosol-generating substrate 120 of the aerosol-generating article 100 .

[0204] 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 other optional embodiments, the thickness of the functional layer 110 made of a paper material is 0.1 to 0.5 cm.

[0205] In some embodiments, the temperature resistance range of the functional layer 110 is 150-350°C.

[0206] For example Figure 3 A schematic diagram showing the preparation of an aerosol generating article 100 having a laminate structure in one embodiment; Figure 3 As shown, the preparation includes:

[0207] S10, laying the base layer 130 flat on the conveyor belt 1a, and driving the base layer 130 to be conveyed in a predetermined direction by a mobile device such as the conveyor belt 1a; wherein the conveyor belt 1a is driven by a rotating wheel to provide a conveying power;

[0208] S20, preparing a slurry from 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;

[0209] S30, the functional layer 110 is pressed onto the surface of the aerosol generating substrate 120 by a pressing roller 3a, and the aerosol generating product 100 is obtained.

[0210] or Figure 4 A schematic diagram showing the preparation of an aerosol generating article 100 having a laminate structure according to another embodiment; Figure 4 As shown, the aerosol generating article 100 is prepared by a multi-stage rolling process. Specifically, the preparation of the multi-stage rolling process includes:

[0211] S10a, firstly, the raw material for forming the aerosol generating matrix 120 is formed into a sheet-shaped aerosol generating matrix 120 by a rolling process through a first pressing roller wheel 1b;

[0212] S20a, the base layer 130 is evenly laid on the conveyor belt 2b located downstream of the first roller wheel 1b, and the base layer 130 is driven by the conveyor belt 2b 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 to provide conveying power;

[0214] 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, so as to obtain the aerosol generating product 100.

[0215] Figure 5 A schematic diagram of an aerosol generating system according to an embodiment is shown; Figure 5 As shown, the aerosol generating system comprises:

[0216] an aerosol generating article 100;

[0217] The heating device 300 is used to receive the aerosol generating product 100 and heat it to generate an aerosol for the user to inhale.

[0218] according to Figure 5 As shown, the heating device 300 includes:

[0219] A rechargeable battery cell 310 for power supply;

[0220] The circuit board 32 is, for example, a PCB board or an FPC board, on which a circuit is arranged;

[0221] 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;

[0222] The nozzle 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 nozzle 350 .

[0223] exist Figure 5 As shown in the figure, 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.

[0224] In some embodiments, when the aerosol-generating article 100 is received in the receiving cavity 340 , the plurality of heating elements 331 can directly or indirectly heat the base layer 130 of the aerosol-generating article 100 .

[0225] 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 product 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 product 100, so that the heat generated by the heating elements 331 is conducted to the aerosol generating substrate 120 through the base layer 130.

[0226] according to Figure 5 In the illustrated embodiment, several or more heating elements 331 are discretely arranged; for example, Figure 5 In the embodiment, they are arranged in an array. Accordingly, the aerosol generating substrate 120 of the aerosol generating article 100 includes a plurality of substrate units 121 adapted to 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 the corresponding heating elements 331 to generate aerosols individually. For example, Figure 5 In the embodiment, the substrate units 121 which are continuously arranged may be approximately in a rectangular shape.

[0227] In some embodiments, several or more heating elements 331 are arranged to be independently connected to the circuit board 320, and then independently powered by the circuit board 320, so as to independently perform heating. For example, in some embodiments, several or more heating elements 331 are independently activatable; so that each heating element 331 can only heat the corresponding substrate unit 121 individually.

[0228] In some embodiments, the circuit board 320 is configured to control the heating of several or more heating elements 331 in a predetermined order, one after another. In some embodiments, the circuit board 320 is configured to control the heating of several or more heating elements 331 not to be heated at the same time; so that, for example, when the user takes a puff, the circuit board 320 only controls one heating element 331 to heat and generate an aerosol that satisfies one puff.

[0229] 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, and the amount of total particulate matter (TPM) generated 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.

[0230] In some embodiments, the circuit board 320 controls the predetermined order of the plurality of heating elements 331, which are started one after another in sequence. Specifically, for example: when the user takes the first puff, the circuit board 320 provides power to the first heating element 331 closest to the left for heating, generating an aerosol for one puff; when the user takes the next puff, the circuit board 320 provides power to the second heating element 331 closest to the left for heating, generating an aerosol for one puff; and this is performed sequentially until all the heating elements 331 are heated, the matrix unit of the aerosol generating product 100 has been puffed, and the user is prompted to replace the new aerosol generating product 100. In the above implementation, starting the heating elements 331 separately in sequence instead of starting the heating at the same time means minimizing the unnecessary consumption of the aerosol generating matrix and reducing the waste of energy. Or in some other implementations, the order in which the plurality of heating elements 331 are started in sequence in a predetermined order is performed along the array arrangement direction.

[0231] Or in some other implementation variations, the circuit board 320 controls the plurality of heating elements 331 to be started individually in sequence, without intervals along the arrangement direction of the heating elements 331. Or in some other implementation variations, the circuit board 320 controls the plurality of heating elements 331 to be started individually in sequence, with intervals or in jumps.

[0232] For example, in some embodiments, several or more heating elements 331 can be energized sequentially, that is, each time the user draws, they are energized once, so that aerosol is generated consistently based on each draw. Accordingly, in some embodiments, each user's draw action can be sensed by an airflow sensor such as a microphone or a MEMS sensor; the circuit board 320 sequentially energizes several or more heating elements 331 based on the sensing result of the airflow sensor. In a preferred implementation, the circuit board 320 controls several heating elements 331 to start sequentially in a predetermined order, which is performed according to the user's draw action. And in some other variations of the implementation, the circuit board 320 controls the sequential activation of several heating elements 331, which is performed according to a predetermined interval time; for example, the predetermined interval is between about 30 seconds and 300 seconds.

[0233] For example, in some other embodiments, the circuit board 320 controls the plurality of heating elements 331 to start in sequence according to a predetermined order based on the operation input signal on the above heating device 300. For example, the heating device 300 is provided with input elements, which may include switch buttons, touch operation screens, knobs and other input elements, which can be operated by users to generate input signals; the circuit board 320 controls the plurality of heating elements 331 to start in sequence according to a predetermined order based on the operation input signal formed by the user operating the input element.

[0234] In some embodiments, the circuit board 320 controls the plurality of heating elements 331 to start sequentially in a predetermined order, which is based on the removal or replacement of the aerosol generating article 100. Specifically, in some embodiments, after the circuit board 320 controls the above heating elements 331 to start sequentially, the user is prompted that the aerosol generating article 100 has been consumed, and the user is prompted to replace the aerosol generating article 100 with a new one.

[0235] And in some embodiments, when it is detected that a new aerosol generating article 100 is received again in the receiving chamber 340 of the heating device 300, the heating elements 331 are activated again in sequence according to a predetermined order. The detection of the user replacing a new aerosol generating article 100 can be detected by a sensor; for example, a light sensor or a pressure sensor is provided in the aerosol generating device to sense the aerosol generating article 100 being combined with or removed from the receiving chamber 340, and the user's replacement or consumption of the aerosol generating article 100 is determined based on the combination and removal.

[0236] In some embodiments, the circuit board 320 controls the above heating elements 331 to start sequentially, which is cyclic. For example, in some embodiments, the cycle is performed according to a predetermined number of times; for example, 10 times. Specifically, when the number of times the heating element 331 is started, and / or the number of times the user puffs, and / or the number of times the input signal received by the input element reaches a predetermined number of times, a new cycle is entered to control the heating elements 331 to start sequentially.

[0237] As another example, in some embodiments, the cycle is performed according to the removal or replacement of the aerosol-generating article 100 .

[0238] 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.

[0239] Or in some other embodiments, the circuit board 320 controls the heating of the plurality of heating elements 331 to heat 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 in sequence along the heating start sequence.

[0240] 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 the preheating of the heating elements 331, which can reduce the possibility of thermal decomposition of adjacent multiple substrate units 121.

[0241] For example, in some embodiments, the circuit board 220 is configured to sequentially supply power to the heating element 331 at a given power, so that the heating element 331 reaches the 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 about 200 degrees, or at least 300 degrees, or at least 400 degrees within 0.5 seconds, and stops after maintaining the temperature for about 2.5 seconds.

[0242] In a preferred embodiment, the aerosol generating article 100 may further include:

[0243] One or more color-changing status markers 122 are combined or arranged on one or more substrate units 121 of the aerosol generating substrate 120; the color-changing status markers 122 can change color in response to the heating of the corresponding substrate unit 121 to provide a use state in which the substrate unit 121 is not heated or has been heated; or, the color-changing status marker 122 has a changeable color to provide a color indication associated with the state of whether the substrate unit 121 is heated.

[0244] 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 by 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 purchased directly; in some embodiments,

[0245] Or in some other embodiments, the material of the aerosol generating substrate 120 and / or the substrate unit 121 includes the above color-changing ink, etc.; and then the aerosol generating substrate 120 and / or the substrate unit 121 is configured to change color when heated to prompt the user 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, so that the aerosol generating substrate 120 and / or the substrate unit 121 has a color-changing state indication of whether it is heated by heating.

[0246] 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, or a magnetic field generator for inductive heating, or a resistive heating element, or a combination thereof.

[0247] 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, embossed, etched, deposited or plated heating elements. In some embodiments, the plurality of heating elements 331 are configured as patterned heating elements, such as heating elements with meandering, meandering or spiral geometric shapes and the like.

[0248] In some embodiments, where at least one or all of the several or more heating elements 331 include a resistive heating element, the resistive heating element preferably includes 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 materials 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, stainless steel, and the like.

[0249] In some embodiments, when at least one or all of the plurality of heating elements 331 include induction heating elements, the plurality of heating elements 331 may include a magnetic field generator for induction heating, which generates a magnetic field to induce the substrate layer 130 of the aerosol generating article 100 to be penetrated by the magnetic field and generate heat, thereby heating the substrate unit 121 of the aerosol generating substrate 120. For example, the plurality of heating elements 331 may include an induction coil, such as a planar spiral coil, to generate a magnetic field. In 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 generate heat, thereby heating the substrate unit 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 the magnetic field and generate heat, such as 430 grade stainless steel, Permalloy, etc.

[0250] Alternatively, in some further 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.

[0251] Figure 6 A schematic diagram of an aerosol-generating article 100a suitable for light heating according to another embodiment is shown; in this embodiment, the aerosol-generating article 100a having a laminate structure comprises:

[0252] The aerosol generating substrate 120a, the base layer 130a and the light absorbing layer 140a are arranged in a stacked or laminated manner.

[0253] In an embodiment, the light absorbing layer 140a may include a light absorbing material; or, the reflectivity of the light absorbing layer 140a to the infrared light, laser, or other heating light emitted by the heating element 331 is less than 20%, so that most of the heating light is absorbed by the light absorbing layer 140a and converted into heat energy. Or in a more preferred embodiment, the reflectivity of the light absorbing layer 140a to the infrared light, laser, or other heating light emitted by the heating element 331 is less than 10%.

[0254] exist Figure 6 In the illustrated embodiment, 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 .

[0255] In some embodiments, the light absorbing layer 140a may have a black color, which is advantageous for absorbing light. For example, in some embodiments, the light absorbing layer 140a includes graphite or carbon, etc., which is advantageous for absorbing heating light. Or the light absorbing layer 140a is or includes a carbon layer or a graphite layer.

[0256] Figure 7 and Figure 8 A schematic diagram of an aerosol generating article 100b of yet another embodiment is shown; in this embodiment, the aerosol generating article 100b comprising a multi-layer structure comprises:

[0257] The base layer 130b, for example, the thermally conductive metal or alloy foil material described above, such as aluminum foil, etc.;

[0258] The support layer 150b is bonded to the base layer 130b; the support layer 150b is used to improve the mechanical strength of the aerosol generating article 100b, so that the aerosol generating article 100b can present a harder characteristic, so as to reduce or prevent the sheet-shaped aerosol generating article 100b from bending or deformation;

[0259] The aerosol generating substrate 120b is used to generate aerosol when heated; the aerosol generating substrate 120b is combined with the base layer 130b and is surrounded or placed in the support layer 150b.

[0260] 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.

[0261] 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 fiber, hemp fiber or flax fiber, bamboo fiber, etc.

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 spacing distance between adjacent substrate units of the aerosol-generating substrate 120b is between 0.1 mm and 20 mm.

[0265] In some embodiments, the thermal conductivity of the support layer 150b is less than 2 W / m·k, so as to provide thermal insulation between the discretely arranged substrate units of the aerosol generating substrate 120b; the thermal insulation of the support layer 150b is advantageous for preventing heat transfer to adjacent substrate units when one of the substrate units 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.

[0266] 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.

[0267] Alternatively, in some other embodiments, color-changeable state 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 associated with the state of whether the substrate unit is heated.

[0268] 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.

[0269] according to Figure 7 and Figure 8 As shown, the surfaces of several discrete substrate units of the aerosol-generating substrate 120b have a height difference with the surface of the support layer 150b; or, 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 concave 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.

[0270] 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.

[0271] In some embodiments, the mass of each substrate unit of the aerosol-generating substrate 120b is about 5 mg to 60 mg. In some embodiments, the thickness of each substrate unit of the aerosol-generating substrate 120b is about 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 about 9 mm. 2 ~800mm 2 .

[0272] Fig. 9 Shows Figure 7 and Figure 8 Schematic diagram of a method for preparing an embodiment of an aerosol generating article 100b; in this embodiment, the preparation of the aerosol generating article 100b includes:

[0273] S10b, the mesh support layer 150b having holes 151b is laminated and bonded to the surface of the base layer 130b by gluing and pressing. Fig. 9 As shown by the middle arrow P2;
