[0078] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0079] The terms "first", "second", "third" in the present application are only used for descriptive purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship or movement condition between components, and if the specific posture (as shown in the drawings) changes, the directional indications also change accordingly.

For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0080] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with each other, unless otherwise explicitly stated.

[0081] It is appreciated that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. The terms "vertical", "horizontal", "left", "right", and the like as used herein are used for illustration only and do not in any way limit the position of the elements.

[0082] Referring to Figures 2-14 An embodiment of an aerosol generating article 1 is provided, which can be used in combination with an aerosol generating device 100, such that the aerosol generating article 1 generates an aerosol.

[0083] Referring to Figure 1 An embodiment of an aerosol generating system is provided, which includes an aerosol generating device 100 and an aerosol generating article 1, the aerosol generating device 100 including a heating assembly 2 for heating the aerosol generating article 1, such that the aerosol generating substrate layer 11 of the aerosol generating article 1 generates an aerosol.

[0084] Referring to Figures 2-14 The aerosol generating article 1 includes a support assembly 12 and an aerosol generating substrate layer 11 disposed on a surface of the support assembly 12, the aerosol generating substrate layer 11 being maintained on the surface of the support assembly 12 at all times during use.

[0085] In some embodiments, referring to Figures 5-13 The aerosol generating substrate layer 11 includes a plurality of discrete substrate layers 111 spaced apart from each other, the plurality of discrete substrate layers being arranged in a discrete annular shape along a circumferential direction of the support assembly.

[0086] The heating assembly 2 can heat the plurality of discrete substrate layers 111 in a preset order, such that the plurality of discrete substrate layers 111 generate aerosol in the preset order. The heating assembly 2 can heat another discrete substrate layer 111 after completing heating of one discrete substrate layer 111, such that the another discrete substrate layer 111 generates aerosol. The preset heating duration of the at least two discrete substrate layers 111 can be equal. The preset heating power of the heating assembly 2 to the at least two discrete substrate layers 111 can be equal.

[0087] As a typical example, the amount of aerosol generated by the at least one discrete substrate layer 111 can satisfy the requirement of at least one puff of a user. For example, the amount of aerosol generated by each of the discrete substrate layers 111 can satisfy the requirement of one puff of a user, such that after one discrete substrate layer 111 generates one puff of aerosol, or after a user completes one puff, or after the heating assembly 2 heats one discrete substrate layer 111 for a preset duration, the heating assembly 2 heats another discrete substrate layer 111, or the another discrete substrate layer 111 can be heated.

[0088] In this embodiment, the heating assembly 2 can include a resistive heating element, a radiation light source, and / or a susceptor.

[0089] The resistive heating element can generate Joule heat when current flows through it, and the resistive heating element can heat the aerosol generating article mainly by heat conduction. Suitable resistive heating elements include, but are not limited to, semiconductors such as doped ceramics, conductive ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic and metal materials. Such composite materials can 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 stainless steel, Constantan, 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 superalloys based on nickel, iron, and cobalt, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys.

[0090] The radiant light source is capable of emitting light, where the term "light" is to be interpreted broadly and includes, for example, any of laser light, infrared light, visible light, and ultraviolet light. In general, suitable wavelengths of light can include wavelengths from about 150 nm to about 1 mm. Particularly suitable wavelengths of light include wavelengths from about 350 nm to about 450 nm and from about 900 nm to about 960 nm. For example, the radiant light source can include a light emitting diode (LED) for generating visible light, for example, at a wavelength of about 405 nm. As an alternative, the radiant light source can be a laser diode, or can include at least one laser diode and at least one LED. In some embodiments, the laser diode emits light at a wavelength of about 940 nm.

[0091] The radiant light source can include an infrared light source. The infrared light source can radiate infrared light having a wavelength of 0.75 pm to 1000 pm, preferably far infrared light having a wavelength of 1.5 pm to 400 pm, more preferably far infrared light having a wavelength of 4 pm to 15 pm. The infrared light source can include an infrared coating capable of radiating infrared light when excited by heat or when current passes therethrough, and the infrared coating can heat the aerosol- generating substrate layer 11 mainly by thermal radiation.

[0092] As used herein, the term "susceptor" refers to a material that can convert electromagnetic energy into heat. When located within a varying electromagnetic field, eddy currents induced in the susceptor cause heating of the susceptor. In such embodiments, the susceptor is designed to interface with an aerosol-generating device that includes a magnetic field generator. The magnetic field generator generates a varying magnetic field to heat the susceptor located within the varying magnetic field. In use, the susceptor is located within the varying magnetic field generated by the magnetic field generator. Therein, the magnetic field generator is electrically connected to a power supply assembly that provides the magnetic field generator with electrical current to generate the varying magnetic field. The magnetic field generator can include one or more induction coils that generate the varying magnetic field, which can surround the susceptor. In an embodiment, the aerosol-generating device is capable of generating a varying magnetic field between 1 MHz and 30 MHz, for example, between 2 MHz and 10 MHz, for example, between 5 MHz and 7 MHz. In an embodiment, the aerosol-generating device is capable of generating a varying magnetic field having a field strength (H-field) between 1 and 5 kA / m, for example, between 2 kA / m and 3 kA / m, for example, about 2.5 kA / m.

[0093] Therein, the susceptor can include a metal or carbon. In an embodiment, the susceptor can include a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In an embodiment, the susceptor includes a nickel-iron alloy. In an embodiment, the susceptor includes a 400 series stainless steel, including a 410 grade or 420 grade or 430 grade stainless steel.

[0094] In some embodiments, the support assembly 12 comprises a susceptor 121, and the heating assembly 2 comprises a magnetic field generator 21, so that the heating assembly 2 is capable of emitting a varying magnetic field to heat the susceptor 121 in the support assembly 12, and the susceptor 121 in the support assembly 12 generates heat, at least part of which is used to heat the aerosol generating substrate layer 11, so that the aerosol generating substrate layer 11 generates aerosol.

[0095] Further, the aerosol generating substrate layer 11 is arranged on the surface of the susceptor 121 of the support assembly 12, so that the aerosol generating substrate layer 11 absorbs and utilizes the heat generated by the susceptor 121, which helps to reduce the power consumption of the heating assembly 2 and improve energy utilization.

[0096] In some embodiments, the support assembly 12 comprises a heat conductor 121', and the aerosol generating substrate layer 11 is arranged on the surface of the heat conductor 121' of the support assembly 2. The heat conductor 121' refers to a material with a thermal conductivity of at least 10 W / (m·k), preferably at least 40 W / (m·k), and more preferably at least 100 W / (m·k). Suitable heat conductors 121' include, but are not limited to, stainless steel, graphite, graphene, aluminum, copper, zinc, steel, silver, heat-conductive polymers, or any combination or alloy thereof.

[0097] In this embodiment, the heating assembly 2 can comprise a radiation light source 22.

[0098] The light emitted by the radiation light source 22 can be irradiated on the heat conductor 121', thereby heating the heat conductor 121' to increase the temperature of the heat conductor 121', and then the heat conductor 121' releases heat to heat the aerosol generating substrate layer 11, so that the aerosol generating substrate layer 11 generates aerosol.

[0099] Alternatively, the light emitted by the radiation light source 22 can be irradiated on the aerosol generating substrate layer 11, thereby directly heating the aerosol generating substrate layer 11, so that the aerosol generating substrate layer 11 generates aerosol. Preferably, the aerosol generating substrate layer 11 is arranged facing the radiation light source 22, and the aerosol generating substrate layer 11 can be located between the heat conductor 121' and the radiation light source 22.

[0100] The heat conductor 121' has high thermal conductivity, which helps to uniformly heat the aerosol generating substrate layer 11 arranged on its surface.

[0101] In some embodiments, the aerosol generating substrate layer 11 is arranged in a continuous annular shape along the circumference of the support assembly 12.

[0102] In some embodiments, reference can be made to Figures 2-4The susceptor 121 or the heat conductor 121' comprises a tubular member 13, and the aerosol generating substrate layer 11 comprises a plurality of discrete substrate layers 111 arranged on a surface of the tubular member 13.

[0103] As a typical example, the annular substrate layer 112 can be heated by the heating assembly 360° at the same time, or the heating assembly 2 can heat the annular substrate layer 112 360° at the same time.

[0104] Alternatively, as a typical example, the annular substrate layer 112 can be heated by the heating assembly 2 in segments or zones in a preset order, so that the annular substrate layer 112 can generate aerosol in segments or zones in a preset order.

[0105] In some embodiments, reference can be made to Figure 5 The susceptor 121 or the heat conductor 121' comprises a tubular member 13, and the aerosol generating substrate layer 11 comprises a plurality of discrete substrate layers 111 arranged on a surface of the tubular member 13.

[0106] The plurality of discrete substrate layers 111 are arranged in discrete annular shapes along the circumference of the tubular member 13 at intervals. Alternatively, not shown, the plurality of discrete substrate layers comprise a plurality of first discrete substrate layers and a plurality of second discrete substrate layers, the plurality of first discrete substrate layers are arranged in discrete first annular shapes along the circumference of the tubular member at intervals, and the plurality of second discrete substrate layers are arranged in discrete second annular shapes along the circumference of the tubular member at intervals. The first annular shape and the second annular shape are arranged along the axial direction of the tubular structure, and the first annular shape and the second annular shape can be arranged along the central axis of the tubular member. The first discrete substrate layers and the second discrete substrate layers are arranged at intervals along the axial direction.

[0107] In some embodiments, reference can be made to Figures 6-13 The susceptor 121 or the heat conductor 121' comprises a plurality of discrete members 14 arranged at intervals. In order to have a certain positional relationship between the plurality of discrete members 14, the support assembly 12 further comprises a tubular base 122, and the plurality of discrete members 14 are held on the tubular base 122 and arranged in discrete annular shapes along the circumference of the tubular base 122 at intervals. The aerosol generating substrate layer 11 comprises a plurality of discrete substrate layers 111 arranged one-to-one on the surfaces of the plurality of discrete members 14.

[0108] In some embodiments, the tubular base 122 is mainly made of an insulating material. The insulating material can include paper material, such as hardboard material. The insulating material can include plastic material, including but not limited to PEEK, PI, PPS, PTFE, PA, PC, PMMA, carbon fiber, and the like. The insulating material can include inorganic material, including but not limited to ceramic, glass, or quartz. The insulating material can also include composite material.

[0109] In some embodiments, the tubular base 122 includes a metal material and an insulating layer arranged on the surface of the metal material. The insulating layer can be an insulating coating, such as a glaze layer. The insulating layer can be a metal oxide layer formed by oxidation of the metal material.

[0110] It should be noted that in some embodiments in which the susceptor 121 or the heat conductor 121' includes the tubular member 13, the tubular member 13 can be arranged on the tubular base 122, and the tubular base 122 can support the tubular member 13. Figures 2-5 In some embodiments, the tubular base 122 can also include the tubular member 13, and the tubular member 13 can be arranged on the tubular base 122, and the tubular base 122 can support the tubular member 13.

[0111] In some embodiments, the thermal conductivity of the tubular base 122 is less than the thermal conductivity of the susceptor 121 or the heat conductor 121'.

[0112] In some embodiments in which the susceptor 121 or the heat conductor 121' includes a plurality of discrete members 14 arranged at intervals, on the one hand, the adjacent two discrete members 14 are arranged at intervals such that there is a large thermal resistance between the adjacent two discrete members 14, and on the other hand, the adjacent two discrete members 14 are kept at intervals on the tubular base 122 having a small thermal conductivity, which helps to prevent heat from being transferred from one susceptor 121 or heat conductor 121' to another susceptor 121 or heat conductor 121', thereby reducing the heat cross talk between the adjacent two susceptors 121 or heat conductors 121'.

[0113] In addition, whether the susceptor 121 or the heat conductor 121' includes a plurality of discrete members 14 arranged at intervals or the susceptor 121 or the heat conductor 121' includes the tubular member 13, as long as the susceptor 121 or the heat conductor 121' is kept on the tubular base 122 having a small thermal conductivity, it helps to increase the thermal resistance between the susceptor 121 or the heat conductor 121' and the tubular base 122, reduces the heat dissipation of the susceptor 121 or the heat conductor 121' through the tubular base 122, and reduces the heat absorbed by the tubular base 122 from the susceptor 121 or the heat conductor 121', which helps to reduce the power consumption of the heating assembly 2 and improve the heating efficiency of the heating assembly 2.

[0114] Further, the tubular base 122 has a thermal conductivity less than 10 W / (m·K). And / or, the tubular base 122 has a specific heat capacity at least 0.5 J / (g·K), for example, at least 0.7 J / (g·K), for example, at least 0.8 J / (g·K). The tubular base 122 with a higher specific heat capacity can effectively hinder the speed of heat conduction therethrough, thereby helping to reduce the heat cross-talk between two adjacent susceptors 121 or heat conductors 121'.

[0115] In some embodiments, the thickness of the susceptor 121 or the heat conductor 121' is less than or equal to the thickness of the tubular base 122, thereby helping to reduce the heat consumption of the susceptor 121 or the heat conductor 121' itself when reaching the preset temperature, and helping to reduce the power consumption and improve the heating efficiency of the heating assembly 2.

[0116] The heat conductor 121' has a smaller thickness, which helps to quickly and uniformly distribute heat on the heat conductor 121', and also allows the aerosol generating substrate layer 11 arranged on the heat conductor 121' to be uniformly and quickly heated and generate aerosol.

[0117] In some embodiments, the thickness D1 of the susceptor 121 or the heat conductor 121' can satisfy: 0.02 mm≤D1≤0.2 mm. For example, D1 can be about equal to 0.1 mm.

[0118] The tubular base 122 is used to support the susceptor 121 or the heat conductor 121', so the tubular base 122 needs a certain stiffness. Preferably, the thickness D2 of the tubular base 122 satisfies: 0.05 mm≤D2≤0.5 mm. For example, D2 can be about equal to 0.1 mm.

[0119] In some embodiments, the tubular base 122 can be made of paper, for example, a paper with a thickness less than 0.5 mm, for example, a paper with a thickness less than 0.3 mm, for example, a paper with a thickness less than 0.2 mm. Figures 2-15 In some embodiments, the tubular base 122 can be made of paper, for example, a paper with a thickness less than 0.5 mm, for example, a paper with a thickness less than 0.3 mm, for example, a paper with a thickness less than 0.2 mm.

[0120] Preferably, the area of the susceptor 121 or the heat conductor 121' is slightly larger than the area of the window 1221, so that the susceptor 121 or the heat conductor 121' can be arranged on the outside or the inside of the tubular base 122 and can completely cover the window 1221, preventing the aerosol from leaking through the window 1221.

[0121] Moreover, the area of the susceptor 121 or the heat conductor 121' being larger than the area of the window 1221 also helps to fix the susceptor 121 or the heat conductor 121' on the tubular base 122 by means of adhesion, welding or snap-fitting.

[0122] Of course, the susceptor 121 or the heat conductor 121' can also be fixed on the tubular base 122 by means of insert molding.

[0123] In some embodiments, the ignition point or the melting point of the susceptor 121 or the heat conductor 121' is greater than the ignition point or the melting point of the tubular base 122, which helps to expand the material selection range of the tubular base 122 and reduce the manufacturing cost of the tubular base 122.

[0124] In some embodiments, the window 1221 can have a plurality of windows 1221, and the plurality of windows 1221 are arranged in discrete annular shapes along the circumference of the tubular base 122 at intervals. Figures 2-15 In some embodiments, the window 1221 can have a plurality of windows 1221, and the plurality of windows 1221 are arranged in discrete annular shapes along the circumference of the tubular base 122 at intervals.

[0125] Figures 4-13 In some embodiments, the susceptor 121 or the heat conductor 121' can include a plurality of discrete members 14, and the plurality of discrete members 14 correspondingly cover the plurality of windows 1221.

[0126] In some embodiments, the susceptor 121 or the heat conductor 121' can include a tubular member 13, and the tubular member 13 simultaneously covers the plurality of windows 1221. Figures 2-5 In some embodiments, the aerosol generating substrate layer 11 can include an annular substrate layer 112, and the annular substrate layer 112 is arranged on the surface of the tubular member 13 and extends along the circumference of the tubular member 13 to form a continuous annular shape.

[0127] Figures 2-4 In some embodiments, the aerosol generating substrate layer 11 can include an annular substrate layer 112, and the annular substrate layer 112 is arranged on the surface of the tubular member 13 and extends along the circumference of the tubular member 13 to form a continuous annular shape.

[0128] In some embodiments, the aerosol generating substrate layer 11 can include an annular substrate layer 112, and the annular substrate layer 112 is arranged on the surface of the tubular member 13 and extends along the circumference of the tubular member 13 to form a continuous annular shape. Figure 5 ​​The aerosol generating matrix layer 11 includes a plurality of discrete matrix layers 111 spaced apart from each other. The plurality of discrete matrix layers 111 are all disposed on the surface of the tubular member 13, and each window 1221 has at least one discrete matrix layer 111 corresponding to it. This allows the receptor 121 corresponding to the window 1221 to be heated or the radiation source 22 to emit light mainly corresponding to the window 1221.

[0129] Preferably, the aerosol generating matrix layer 11 is disposed on the surface of the tubular member 13 corresponding to the window 1221. Alternatively, preferably, the aerosol generating matrix layer 11 is disposed on the surface of the tubular member 13 opposite to the window 1221, thereby helping to reduce the difficulty of assembling the tubular member 13 with the aerosol generating matrix layer 11 disposed thereon and the tubular substrate 122 with the window 1221.

[0130] In such Figure 8 and Figure 10 In the illustrated embodiment, the sensor 121 or heat conductor 121 is disposed on the tubular substrate 122 and blocks the window 1221 on the tubular substrate 122. Multiple discrete matrix layers 111 are disposed on the surface of the sensor 121 or heat conductor 121, and each discrete matrix layer 111 is located in one of the multiple windows 1221. In this embodiment, the sensor 121 or heat conductor 121 may include multiple discrete components 14, each discrete component 14 blocking one of the multiple windows 1221, and the multiple discrete matrix layers 111 may be disposed on the surface of the multiple discrete components 14 and located in one of the multiple windows 1221. Alternatively, in this embodiment, the sensor 121 or heat conductor 121 may be a tubular component 13, and multiple discrete matrix layers 111 are disposed on the surface of the tubular component 13, and each discrete matrix layer 111 is located in one of the multiple windows 1221.

[0131] In some embodiments, reference may be made to Figure 1 , Figure 7 , Figure 8 , Figure 13 and Figure 14 The sensor 121 or heat conductor 121 is disposed on the outer side or outer surface of the tubular substrate 122. In some embodiments, reference can be made to... Figure 3 , Figure 4 , Figure 9 , Figure 10 and Figure 12 The sensor 121 or the heat conductor 121 is disposed on the inner side or inner surface of the tubular substrate 122.

[0132] In some embodiments, reference may be made to Figures 11-13The aerosol-generating substrate layer 111 includes an inner aerosol-generating substrate layer 113 and an outer aerosol-generating substrate layer 114. The inner aerosol-generating substrate layer 113 is disposed on an inner surface of the susceptor 121 or the heat conductor 121'. The outer aerosol-generating substrate layer 114 is disposed on an outer surface of the susceptor 121 or the heat conductor 121'.

[0133] In some embodiments, the discrete substrate layer 111 includes an inner discrete substrate layer 111' and an outer discrete substrate layer 111".

[0134] Example 1: Not shown, the inner surface of the tubular member 13 can be provided with at least one inner discrete substrate layer 111', while the outer surface of the tubular member 13 can be provided with at least one outer discrete substrate layer 111".

[0135] Example 2: Referring to Figures 11-13 The inner surface of the at least one discrete member 14 is provided with at least one inner discrete substrate layer 111', while the outer surface of the at least one discrete member 14 can be provided with at least one outer discrete substrate layer 111".

[0136] In some embodiments, not shown, the annular substrate layer 112 includes an inner annular substrate layer and an outer annular substrate layer. The inner surface of the tubular member 13 can be provided with the inner annular substrate layer, while the outer surface of the tubular member 13 can be provided with the outer annular substrate layer.

[0137] It is noted that the tubular substrate 133 is optional when the aerosol-generating article 1 includes the tubular member 13.

[0138] In some embodiments, referring to Figure 1 The aerosol-generating device 100 or the aerosol-generating article 1 further includes a mouthpiece 3 for a user to hold in the mouth. The user can draw the aerosol generated by the aerosol-generating substrate layer 11 by drawing the mouthpiece 3.

[0139] When the aerosol-generating article 1 includes the mouthpiece 3, the mouthpiece 3 of the aerosol-generating article 1 is exposed outside the aerosol-generating device 100 when the aerosol-generating article 1 is combined with the aerosol-generating device 100 for a user to hold in the mouth.

[0140] When the aerosol-generating device 100 includes the mouthpiece 3, the aerosol-generating article 1 can be completely hidden inside the aerosol-generating device 100. It is preferred that the aerosol-generating device 100 includes the mouthpiece 3.

[0141] In some embodiments, referring to Figure 1The aerosol-generating system further includes an airflow passage 4 that communicates the mouthpiece 3 with the aerosol-generating substrate layer 11, the airflow passage 4 being configured to guide the aerosol generated by the aerosol-generating substrate layer 11 toward the mouthpiece 3. In the airflow direction, the mouthpiece 3 is positioned downstream of the aerosol-generating substrate layer 11.

[0142] In some embodiments, reference can be made to Figure 18 and Figure 19 The heating assembly 2 includes a first heating assembly 23 that is positioned inside the support assembly 12 when the aerosol-generating article 1 is combined with the aerosol-generating device 100, so that the first heating assembly 23 is surrounded by the support assembly 12. The first heating assembly 23 is configured to heat the aerosol-generating substrate layer 11 from the inside of the support assembly 12, so that the aerosol-generating substrate layer 11 generates the aerosol.

[0143] When the aerosol-generating substrate layer 11 is provided on the inner surface of the support assembly 12 (or the susceptor 121 / the heat conductor 121'), at least a portion of the airflow passage 4 is positioned between the inner surface of the support assembly 12 and the first heating assembly 23. Further, at least a portion of the airflow passage 4 can be positioned between the first heating assembly 23 and the aerosol-generating substrate layer 11 provided on the inner surface of the support assembly 12, so that the first heating assembly 23 is spaced apart from the aerosol-generating substrate layer 11.

[0144] When the aerosol-generating substrate layer 11 is provided on the outer surface of the support assembly 12 (or the susceptor 121 / the heat conductor 121'), at least a portion of the airflow passage 4 is positioned outside the support assembly 12.

[0145] When the aerosol-generating substrate layer 11 is provided on both the outer surface and the inner surface of the support assembly 12 (or the susceptor 121 / the heat conductor 121'), a portion of the airflow passage 4 is positioned outside the support assembly 12, and a portion of the airflow passage 4 is positioned inside the support assembly 12.

[0146] In some embodiments, reference can be made to Figure 16 and Figure 17 The heating assembly 2 includes a second heating assembly 24 that is positioned outside the support assembly 12 when the aerosol-generating article 1 is combined with the aerosol-generating device 100, so that the second heating assembly 24 is configured to heat the aerosol-generating substrate layer 11 from the outside of the support assembly 12, so that the aerosol-generating substrate layer 11 generates the aerosol.

[0147] When the aerosol generating substrate layer 11 is provided on the outer surface of the support assembly 12 (or the susceptor 121 / heat conductor 121'), at least a portion of the airflow passage 4 is located between the outer surface of the support assembly 12 and the second heating assembly 24. Further, at least a portion of the airflow passage 4 can be located between the second heating assembly 24 and the aerosol generating substrate layer 11 provided on the outer surface of the support assembly 12, so that the second heating assembly 24 is spaced apart from the aerosol generating substrate layer 11.

[0148] When the aerosol generating substrate layer 11 is provided on the inner surface of the support assembly 12 (or the susceptor 121 / heat conductor 121), at least a portion of the airflow passage 4 is located on the inner side of the support assembly 12.

[0149] In some embodiments, the heating assembly 2 comprises both the first heating assembly 23 and the second heating assembly 24, and the first heating assembly 23 and the second heating assembly 24 are located on opposite sides of the support assembly 12.

[0150] The first heating assembly 23 and the second heating assembly 24 can be the same heating assembly 2, for example, the first heating assembly 23 and the second heating assembly 24 can each comprise the magnetic field generator 21, or the first heating assembly 23 and the second heating assembly 24 can each comprise the radiation light source 22. The first heating assembly 23 and the second heating assembly 24 can be different heating assemblies, for example, one of the first heating assembly 23 and the second heating assembly 24 can comprise the magnetic field generator 21, and the other can comprise the radiation light source 22.

[0151] When both the first heating assembly 23 and the second heating assembly 24 are present, the first heating assembly 23 and the second heating assembly 24 can be configured to work simultaneously, or can be configured to work at different times.

[0152] In some embodiments, with reference to Figures 16-21 The heating assembly 2 comprises the radiation light source 22, which is configured to emit light along the radial direction of the support assembly 12 to irradiate at least a portion of the aerosol generating substrate layer 11. Based on this, the radiation light source 22 can be located on the inner side and / or the outer side of the support assembly 12.

[0153] In some embodiments, with reference to Figure 16 and Figure 18 The irradiation angle of the radiation light source 22 in the circumferential direction of the support assembly 12 is less than 360°. Thus, the radiation light source 22 cannot irradiate the annular substrate layer 112 at 360°, or cannot simultaneously irradiate all the discrete substrate layers 111 arranged in discrete annular shapes.

[0154] As a typical example, the aerosol generating article 1 is configured to rotate relative to the radiation source 22 so that the aerosol generating matrix layer 11 can be irradiated by the radiation source 22 in a predetermined sequence. This allows for full utilization of the aerosol generating matrix layer 11 and helps ensure that the aerosol generating matrix layer 11 is adequately irradiated by the light emitted by the radiation source 22, thereby enabling the aerosol generating matrix layer 11 to generate aerosols sufficiently. For example, the aerosol generating article 1 can be configured to rotate at least 270° relative to the radiation source 22. Preferably, the aerosol generating article 1 can rotate 360° relative to the radiation source 22.

[0155] In such Figures 2-13 In the illustrated embodiment, the support component 12 is constructed as a tubular structure with a circular cross-section, and a positioning mechanism 1222 is provided on the support component 12. The driving mechanism in the aerosol generating device 100 can act on the positioning mechanism 1222, thereby driving the aerosol generating article 1 to rotate relative to the radiation source 22. The positioning mechanism 1222 can be a through hole formed in the tubular component 13 or the tubular substrate 122. Multiple through holes can be provided, and these through holes can be symmetrically or evenly distributed on the tubular component 13 or the tubular substrate 122.

[0156] Alternatives, in such Figure 14 and Figure 15 In the illustrated embodiment, the support component 12 is constructed as a tubular structure with a polygonal cross-section. The inner wall of the chamber in the aerosol generating apparatus 100 for receiving the aerosol-generated article 1 can have the same shape as the outer surface of the tubular structure, thereby allowing the tubular structure to be non-rotatably disposed within the chamber. The drive mechanism in the aerosol generating apparatus 100 can drive the chamber to rotate, thereby driving the aerosol-generated article 1 to rotate relative to the radiation source 22.

[0157] Alternatively, the radiation source 22 is configured to be rotatable, so that the radiation source 22 irradiates the aerosol generation matrix layer 11 in a preset sequence. For example, the drive mechanism in the aerosol generation apparatus 100 can act on the radiation source 22, thereby driving the radiation source 22 to rotate relative to the aerosol generation article 1. For example, the radiation source 22 can be configured to rotate at least 270°. Preferably, the radiation source 22 can rotate 360°.

[0158] As another typical example, see [reference] Figure 17 and Figure 19The plurality of radiation light sources 22 are arranged in discrete ring-shaped light sources, and are configured to emit light in a predetermined order to irradiate the aerosol generating substrate layer 11 in the predetermined order, thereby enabling the aerosol generating substrate layer 11 to be fully utilized and enabling the aerosol generating substrate layer 11 to be fully irradiated with light emitted by the radiation light sources 22 in the predetermined order, thereby enabling the aerosol generating substrate layer 11 to sufficiently generate aerosol.

[0159] For example, the plurality of radiation light sources 22 include a plurality of light emitting diodes or laser diodes arranged in a ring-shaped dot matrix, and diodes or groups of diodes (a group of diodes includes a plurality of diodes) in the dot matrix are controlled to emit light and be turned off in the predetermined order, thereby enabling the aerosol generating substrate layer 11 to be fully irradiated with light emitted by the radiation light sources 22 in the predetermined order.

[0160] For example, the plurality of radiation light sources 22 include a plurality of infrared coating layers arranged in a ring shape, and the plurality of infrared coating layers are controlled to emit heat and thereby emit infrared light in the predetermined order, thereby enabling the aerosol generating substrate layer to be fully irradiated with light emitted by the radiation light sources.

[0161] For example, the plurality of radiation light sources 22 include a ring-shaped infrared coating layer, and different regions of the ring-shaped infrared coating layer are controlled to emit heat and thereby emit infrared light in the clockwise direction or the counterclockwise direction, thereby enabling the aerosol generating substrate layer 11 to be fully irradiated with light emitted by the radiation light sources 22 in the predetermined order.

[0162] Of course, the plurality of radiation light sources 22 can be simultaneously turned on to irradiate the support assembly 12 in 360°.

[0163] The plurality of radiation light sources 22 arranged in discrete ring-shaped light sources can be located inside the support assembly 12 to be surrounded by the support assembly 12. The plurality of radiation light sources 22 arranged in discrete ring-shaped light sources can be located outside the support assembly 12 to surround the support assembly 12.

[0164] In some embodiments, the aerosol generating substrate layer 11 comprises N discrete substrate layers 111, the radiation light source 22 has one or a group (a group of radiation light sources 22 comprises a plurality of radiation tubes 22), and one or the group of radiation light sources 22 corresponds to a part of the N discrete substrate layers 111. The aerosol generating article 1 is configured to be rotatable relative to the radiation light source 22 for M times, or the aerosol generating article 1 or the radiation light source 22 is configured to be rotatable for M times. Each time the aerosol generating article 1 or the radiation light source 22 rotates, another part of the N discrete substrate layers 111 replaces the original part of the N discrete substrate layers 111 corresponding to the radiation light source 22. After the aerosol generating article 1 or the radiation light source 22 rotates for M-1 times, all of the N discrete substrate layers 111 are irradiated by the light emitted by the radiation light source 22. After the aerosol generating article 1 or the radiation light source 22 rotates for M times, the aerosol generating article 1 or the radiation light source 22 returns to the original position. Wherein, M and N are both integers greater than 1. M can be equal to N. M can not be equal to N.

[0165] In some embodiments, the plurality of radiation light sources 22 are arranged in a discrete annular shape in the circumferential direction, the plurality of discrete substrate layers 111 are arranged in a discrete annular shape in the circumferential direction, and the plurality of radiation light sources 22 are arranged one-to-one corresponding to the plurality of discrete substrate layers 111. The plurality of radiation light sources 22 are configured to emit light in sequence in the clockwise or counterclockwise order, so that the plurality of discrete substrate layers 111 are irradiated in sequence.

[0166] In some embodiments, the plurality of radiation light sources 22 are arranged in a discrete annular shape in the circumferential direction, the annular substrate layer 112 is located in the surrounding range of the plurality of radiation light sources 22, or the annular substrate layer 112 surrounds the periphery of the plurality of radiation light sources 22. The plurality of radiation light sources 22 are configured to emit light in sequence in the clockwise or counterclockwise order, so that the area of the annular substrate layer 112 is irradiated in sequence. Preferably, the plurality of radiation light sources 22 are arranged in a discrete annular shape uniformly distributed.

[0167] In some embodiments, reference can be made to Figure 20 and Figure 21 The irradiation length of the radiation light source 22 in the axial direction of the support assembly 12 is less than the extension length L of the aerosol generating substrate layer 11 in the axial direction. Thus, when the radiation light source 22 emits light, part of the aerosol generating substrate layer 11 in the axial direction is located outside the irradiation range.

[0168] As a typical example, the aerosol generating article 1 is configured to be movable along the axial direction of the support assembly 12 relative to the radiation light source 22, so that the aerosol generating substrate layer 11 can be irradiated by the radiation light source 22 in a preset order. Thus, the aerosol generating substrate layer 11 can be fully utilized, and the aerosol generating substrate layer 11 can be fully irradiated by the light emitted by the radiation light source 22, so that the aerosol generating substrate layer 11 can fully generate aerosol.

[0169] The driving mechanism in the aerosol generating device 100 can act on the positioning mechanism 1222 or the cartridge, so as to drive the aerosol generating article 1 to move relative to the radiation light source 22 in the axial direction. Alternatively, the driving mechanism in the aerosol generating device 100 can act on the radiation light source 22, so as to drive the radiation light source 22 to move in the axial direction.

[0170] Among them, the radiation light source 22 can be arranged as a ring-shaped light source, and the ring-shaped light source can be located on the inner side or the outer side of the support assembly 12, so that the ring-shaped light source can irradiate the support assembly 12 at 360°. Alternatively, a plurality of radiation light sources 22 can be arranged, and the plurality of radiation light sources 22 can be arranged as discrete ring-shaped light sources, which can be located on the inner side or the outer side of the support assembly 12, so that the discrete ring-shaped light sources can irradiate the support assembly 12 at 360°. Thus, the driving mechanism drives the support assembly 12 to move relative to the ring-shaped light source or the discrete ring-shaped light source capable of irradiating the support assembly 12 at 360° in the axial direction, or drives the ring-shaped light source or the discrete ring-shaped light source capable of irradiating the support assembly 12 at 360° to move relative to the support assembly 12 in the axial direction, so that the aerosol generating substrate layer 11 can be fully irradiated by the light emitted by the radiation light source 12 in a preset order.

[0171] As another typical example, referring to Figure 21 , the radiation light source 22 has a plurality of radiation light sources 22 arranged along the axial direction of the support assembly 12, and the plurality of radiation light sources 22 are configured to emit light in a preset order to irradiate the aerosol generating substrate layer 111 in a preset order.

[0172] For example, the plurality of radiation light sources 22 include a plurality of light emitting diodes or laser diodes, and the plurality of diodes are arranged in a strip-shaped dot matrix along the axial direction of the support assembly. The diodes or diode groups (a diode group includes a plurality of diodes) in the dot matrix are controlled to emit light and turn off in a preset order, so that the aerosol generating substrate layer 11 can be fully irradiated by the light emitted by the radiation light source in a preset order.

[0173] For example, the plurality of radiation light sources 22 can constitute a plurality of annular light sources or a plurality of discrete annular light sources, and the plurality of annular light sources and / or the plurality of discrete annular light sources can be arranged in the axial direction of the support assembly 12 and controlled to emit light in sequence in one direction in the axial direction and to be turned off, so that the aerosol generating substrate layer 11 is sufficiently irradiated with light emitted from the radiation light sources in a predetermined order.

[0174] For example, a plurality of infrared coating layers can be provided, the plurality of infrared coating layers can be arranged in the axial direction of the support assembly, and the plurality of infrared coating layers can be controlled to emit heat in sequence in a predetermined order to radiate infrared light, so that the aerosol generating substrate layer is sufficiently irradiated with light emitted from the radiation light sources.

[0175] For example, the plurality of radiation light sources 22 can include an annular infrared coating layer, and different regions of the annular infrared coating layer can be controlled to emit heat and radiate infrared light in sequence in one direction in the axial direction, so that the aerosol generating substrate layer 11 is sufficiently irradiated with light emitted from the radiation light sources in a predetermined order.

[0176] In some embodiments, when the heating assembly 2 includes the radiation light source 22, the support assembly 12 includes a heat conductor 121', the aerosol generating substrate layer 11 is disposed on a surface of the heat conductor 121', and the heat conductor 121' and the radiation light source 22 are located on opposite sides of the aerosol generating substrate layer 11. The heat conductor 121' can serve to hold the aerosol generating substrate layer 11 and to help the aerosol generating substrate layer 11 be uniformly heated, and can also intercept light emitted from the radiation light source 22 to prevent the light from passing through the window 1221 or the support assembly 12.

[0177] In some embodiments, the heating assembly 2 includes a magnetic field generator 21 for emitting a varying magnetic field, and the support assembly 12 includes a susceptor 121, and the aerosol generating substrate layer 11 is disposed on a surface of the susceptor 121.

[0178] In some embodiments, the magnetic field generator 21 has a magnetic field coverage angle in the circumferential direction of the support assembly 12 less than 360°. Thus, the magnetic field emitted by the magnetic field generator 21 cannot cover the annular substrate layer 112 or the tubular susceptor 121 by 360°, or cannot simultaneously cover all the discrete substrate layers 111 arranged in discrete annular form or the discrete susceptors 121 by 360°. It should be noted that the magnetic field cannot cover the susceptor 121 or the aerosol generating substrate layer 11 means that the magnetic field intensity in the area of the susceptor 121 or the aerosol generating substrate layer 11 that is not covered by the magnetic field is small, and is not sufficient to cause the susceptor 121 to generate heat to cause the corresponding aerosol generating substrate layer 11 to generate aerosol. The magnetic field intensity in the area of the susceptor 121 or the aerosol generating substrate layer 11 that is covered by the magnetic field is large, and is sufficient to cause the susceptor 121 to generate heat to cause the corresponding aerosol generating substrate layer 11 to generate aerosol. Therefore, the susceptor 121 in the area covered by the magnetic field emitted by the magnetic field generator 21 can generate heat to cause the corresponding aerosol generating substrate layer 11 to generate aerosol, and the remaining area is collectively referred to as the area not covered by the magnetic field emitted by the magnetic field generator 21.

[0179] As a typical example, the aerosol generating article 1 is configured to be rotatable relative to the magnetic field generator 21 so that the susceptor 121 can be covered by the magnetic field emitted by the magnetic field generator 21 in a predetermined order. Thus, the aerosol generating substrate layer 11 can be fully utilized, and the aerosol generating substrate layer 11 can be fully covered by the magnetic field emitted by the magnetic field generator 21, thereby enabling the aerosol generating substrate layer 11 to fully generate aerosol. For example, the aerosol generating article 1 can be configured to be rotatable relative to the generator 21 by at least 270°. Preferably, the aerosol generating article 1 can be rotatable relative to the generator 21 by 360°.

[0180] The driving mechanism in the aerosol generating device 100 can act on the positioning mechanism 1222 or the cartridge, thereby driving the aerosol generating article 1 to rotate relative to the magnetic field generator 21.

[0181] Alternatively, the magnetic field generator 21 is configured to be rotatable, and the magnetic field emitted by the magnetic field generator 21 in a predetermined order by rotating the magnetic field generator 21 covers the aerosol generating substrate layer 11 and the susceptor 121. For example, the driving mechanism in the aerosol generating device 100 can act on the magnetic field generator 21, thereby driving the magnetic field generator 21 to rotate relative to the aerosol generating article 1. For example, the magnetic field generator 21 can be configured to be rotatable by at least 270°. Preferably, the magnetic field generator 21 can be rotatable by 360°.

[0182] As another typical example, reference can be made to Figure 17 and Figure 19The magnetic field generator 21 has a plurality of magnetic field generators 21 arranged in a discrete ring shape. The plurality of magnetic field generators 21 is configured to work in a preset order so that the magnetic field covers the aerosol generating substrate layer 11 and the susceptor 121 in the preset order.

[0183] The plurality of magnetic field generators 21 arranged in a discrete ring shape can be located inside the support assembly 12, thereby being surrounded by the support assembly 12. The plurality of magnetic field generators 21 arranged in a discrete ring shape can be located outside the support assembly 12, thereby surrounding the support assembly 12.

[0184] Of course, the plurality of magnetic field generators 21 can be configured to emit the magnetic field at the same time, thereby enabling the magnetic field to cover the support assembly 12 by 360°.

[0185] In some embodiments, the aerosol generating substrate layer 11 includes N discrete substrate layers 111, and the magnetic field generator 21 has one or a group of magnetic field generators 21 corresponding to a part of the N discrete substrate layers 111. The aerosol generating article 1 is configured to be rotated M times relative to the magnetic field generator 21, or the aerosol generating article 1 or the magnetic field generator 21 is configured to be rotated M times. Each time the aerosol generating article 1 or the magnetic field generator 21 is rotated, another part of the N discrete substrate layers 111 is replaced with the part of the N discrete substrate layers 111 corresponding to the magnetic field generator 21. After the aerosol generating article 1 or the magnetic field generator 21 is rotated M-1 times, all of the N discrete substrate layers 111 are covered by the magnetic field emitted by the radiation light source 22. After the aerosol generating article 1 or the magnetic field generator 21 is rotated M times, the aerosol generating article 1 or the magnetic field generator 21 returns to the original position. Here, M and N are each an integer greater than 1. M can be equal to N. M can not be equal to N.

[0186] In some embodiments, the plurality of magnetic field generators 21 is arranged in a discrete ring shape in the circumferential direction, the plurality of discrete substrate layers 111 is arranged in a discrete ring shape in the circumferential direction, and the plurality of magnetic field generators 21 is arranged corresponding to the plurality of discrete substrate layers 111 one by one. The plurality of magnetic field generators 21 is configured to emit the magnetic field in a clockwise or counterclockwise order, thereby enabling the plurality of discrete substrate layers 111 to be covered by the magnetic field one by one.

[0187] In some embodiments, a plurality of magnetic field generators 21 are arranged in a discrete ring around the periphery, with an annular matrix layer 112 located within the surrounding area of ​​the plurality of magnetic field generators 21, or the annular matrix layer 112 surrounds the periphery of the plurality of magnetic field generators 21. The plurality of magnetic field generators 21 are configured to emit magnetic fields sequentially in a clockwise or counterclockwise order, such that the region of the annular matrix layer 112 is sequentially covered by the magnetic field. Preferably, the plurality of magnetic field generators 21 are arranged in a uniformly distributed discrete ring.

[0188] In some embodiments, reference may be made to Figure 20 and Figure 21 The magnetic field coverage length of the magnetic field generator 21 in the axial direction of the support assembly 12 is less than the axial extension length L1 of the sensor 121. Therefore, when the magnetic field generator 21 emits a magnetic field, a portion of the sensor 121 in the axial direction is outside the coverage area of ​​the magnetic field.

[0189] As a typical example, the aerosol generating article 1 is configured to move relative to the magnetic field generator 21 along the axis of the support assembly 12 so that the receptor 121 can be covered by the magnetic field emitted by the magnetic field in a preset sequence.

[0190] The drive mechanism in the aerosol generating device 100 can act on the positioning mechanism 1222 or the chamber, thereby driving the aerosol generated article 1 to move axially relative to the magnetic field generator 21. Alternatively, the drive mechanism in the aerosol generating device 100 can act on the magnetic field generator 21, thereby driving the magnetic field generator 21 to move axially.

[0191] The magnetic field generator 21 can be configured as a spiral induction coil, positioned inside or outside the support assembly 12, so that the magnetic field emitted by the spiral induction coil can cover the support assembly 12 360°. Alternatively, multiple disc-shaped induction coils can be configured and arranged in discrete rings, positioned inside or outside the support assembly 12, so that the magnetic field emitted by the discrete rings can cover the support assembly 12 360°. The driving mechanism then drives the support assembly 12 to move axially relative to the induction coils that emit the magnetic field that covers the support assembly 12 360°, or drives the induction coils that emit the magnetic field that covers the support assembly 12 360° to move axially relative to the support assembly 12, ensuring that the aerosol generation matrix layer 11 is fully covered by the magnetic field emitted by the magnetic field generator 21 in a preset order.

[0192] As another typical example, see [reference] Figure 21The magnetic field generator 21 has a plurality of magnetic field generators 21 arranged in an axial direction of the support assembly 12, and the plurality of magnetic field generators 21 are configured to operate in a predetermined order so that the magnetic field covers the susceptor 121 in the predetermined order.

[0193] For example, the plurality of magnetic field generators 21 include a plurality of spiral inductive coils or a plurality of disc inductive coils arranged in the axial direction of the support assembly 12, and the plurality of spiral inductive coils or the plurality of disc inductive coils are controlled to sequentially emit the magnetic field in one direction in the axial direction so that the susceptor 121 is covered by the magnetic field in the predetermined order in the axial direction.

[0194] For example, the plurality of magnetic field generators 21 include a plurality of spiral inductive coils or a plurality of disc inductive coils arranged in the axial direction of the support assembly 12, and the plurality of spiral inductive coils or the plurality of disc inductive coils are controlled to sequentially emit the magnetic field in one direction in the axial direction so that the susceptor 121 is covered by the magnetic field in the predetermined order in the axial direction.

[0195] In some embodiments, the heating assembly 2 is spaced apart from the aerosol generating substrate layer 11 to prevent abrasion of the aerosol generating substrate layer 11 when the aerosol generating article 1 is combined with the aerosol generating device 100 or to prevent residue on the aerosol generating substrate layer 11 from adhering to the heating assembly 2 when the aerosol generating article 1 is removed from the aerosol generating device 100.

[0196] In some embodiments, the heating assembly 2 is spaced apart from the susceptor 121 or the heat conductor 121'. This prevents abrasion of the heating assembly 2 when the aerosol generating article 1 is combined with the aerosol generating device 100 or reduces the conduction of heat from the susceptor 121 to the magnetic field generator 21 when the susceptor 121 is heated.

[0208] As used herein, the term "aerosol generating matrix layer 11" refers to a substrate comprising an aerosol generating matrix capable of releasing volatile substances to form an inhalable aerosol. The aerosol generating matrix layer may include tobacco-containing material containing volatile tobacco flavor compounds that are released from the aerosol generating matrix upon heating. Specifically, the aerosol generating matrix layer may be a tobacco-containing aerosol generating matrix layer, preferably a solid tobacco-containing aerosol generating matrix layer. Alternatively, the aerosol generating matrix layer may include non-tobacco materials. The aerosol generating matrix layer may also include an aerosol forming agent. Examples of suitable aerosol forming agents are glycerol and propylene glycol.

[0209] The aerosol-generating substrate layer may, if desired, contain additional tobacco or non-tobacco volatile flavour compounds which are released upon heating of the aerosol- generating substrate layer. The aerosol-generating substrate layer may also contain micro- encapsulations, for example containing additional tobacco or non-tobacco volatile flavour compounds, and such micro-encapsulations can melt during heating of the solid aerosol- generating substrate layer.

[0210] Preferably, the aerosol-generating substrate layer 11 is a tobacco sheet comprising tobacco material, fibres, a binder and an aerosol former. Preferably, the tobacco sheet is a cast leaf.

[0211] The tobacco particles can be in the form of tobacco dust having a particle size of about 30 microns to 250 microns, preferably about 30 microns to 80 microns or 100 microns to 250 microns, depending on the desired sheet thickness and the casting gap, wherein the casting gap typically defines the thickness of the sheet.

Alternatively, fibres such as vegetable fibres can be used together with the fibre particles described above, or in the alternative, bamboo is included.
