[0002] This application claims priority to Chinese Patent Application No. 202411653329.8, filed on November 18, 2024, entitled "Aerosol generating article and aerosol generating system comprising the article", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of aerosol generation technology, and in particular to an aerosol generating article and an aerosol generating system comprising the article. Background Technology

[0004] An aerosol generating article is an article capable of generating aerosols for a user to inhale when heated without combustion. In some exemplary prior art, an aerosol generating article includes a first rotating wheel, a strip wound into a disc shape on the first rotating wheel, an aerosol generating matrix disposed on the strip, and a second rotating wheel. The strip is connected to the second rotating wheel and can be gradually transferred from the first rotating wheel to the second rotating wheel under the rotation of the second rotating wheel. The aerosol generating matrix on the strip located between the first and second rotating wheels is exposed, so that during the process of the strip transferring from the first rotating wheel to the second rotating wheel, the aerosol generating matrix on the strip is sequentially exposed and sequentially passes through the heating component in the aerosol generating device to be heated to generate aerosols.

[0005] However, the conveyor belt is prone to jamming as it passes through the heating component, affecting the user experience.

[0085] Please refer to Figures 2-14. This application provides an embodiment of an aerosol generating article 1, which can be used in conjunction with an aerosol generating device 100 to generate aerosols.

[0086] Referring to Figure 1, this application provides an embodiment of an aerosol generation system. The aerosol generation system includes an aerosol generation device 100 and an aerosol generation article 1. The aerosol generation device 100 includes a heating component 2, which is used to heat the aerosol generation article 1 so that the aerosol generation matrix layer 11 in the aerosol generation article 1 generates aerosols.

[0087] Please refer to Figures 2-14. The aerosol generating article 1 includes a support component 12 and an aerosol generating matrix layer 11 disposed on the surface of the support component 12. During use, the aerosol generating matrix layer 11 can always remain on the surface of the support component 12.

[0088] In some embodiments, referring to Figures 5-13, the aerosol generation matrix layer 11 includes a plurality of discrete matrix layers 111 spaced apart from each other, and the plurality of discrete matrix layers 111 are arranged in discrete rings along the circumference of the support component 12.

[0089] The heating component 2 can heat multiple discrete matrix layers 111 in a preset order, causing the multiple discrete matrix layers 111 to generate aerosols in the preset order. The heating component 2 can heat one discrete matrix layer 111 before heating another discrete matrix layer 111, causing the other discrete matrix layer 111 to generate aerosols. The preset heating durations for at least two discrete matrix layers 111 can be equal. The preset heating power of the heating component 2 for at least two discrete matrix layers 111 can be equal.

[0090] As a typical example, the amount of aerosol generated by at least one discrete matrix layer 111 is sufficient to meet the user's need for at least one inhalation. For example, the amount of aerosol generated by each discrete matrix layer 111 is sufficient to meet the user's need for one inhalation, so that after one discrete matrix layer 111 has generated a complete aerosol, or after the user has completed one inhalation, or after the heating component 2 has heated one discrete matrix layer 111 for a preset time, the heating component 2 can then heat another discrete matrix layer 111, or another discrete matrix layer 111 can only be heated.

[0091] In this embodiment, the heating component 2 may include a resistance heating element, a radiation light source, and / or a sensor.

[0092] Resistance heating elements generate Joule heat when an electric current flows through them, and can heat aerosol-generated products primarily through heat conduction. Suitable resistance 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 metallic 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 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 nickel-, iron-, and cobalt-based superalloys, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys.

[0093] A radiation source is capable of emitting light, and the term "light" here should generally be interpreted broadly to include, for example, any of laser light, infrared light, visible light, and ultraviolet light. Typically, 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, a radiation source may include a light-emitting diode (LED) for generating visible light, for example, at a wavelength of about 405 nm. Alternatively, a radiation source may be a laser diode, or may 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.

[0094] The radiation source may include an infrared source. The infrared source can radiate infrared light with wavelengths from 0.75 μm to 1000 μm, preferably far-infrared light with wavelengths from 1.5 μm to 400 μm, and more preferably far-infrared light with wavelengths from 4 μm to 15 μm. The infrared source may include an infrared coating, which radiates infrared light when heated or when an electric current passes through it. The infrared coating can primarily heat the aerosol to form the matrix layer 11 through thermal radiation.

[0095] As used herein, the term "sensor" refers to a material capable of converting electromagnetic energy into heat. Eddy currents induced in the sensor when it is located within a changing electromagnetic field cause heating of the sensor. In such embodiments, the sensor is designed to engage with an aerosol generating device 100 including a magnetic field generator. The magnetic field generator generates a changing magnetic field to heat the sensor located within the changing magnetic field. In use, the sensor is located within the changing magnetic field generated by the magnetic field generator. The magnetic field generator is electrically connected to a power supply assembly, and the aerosol generating device 100 provides the magnetic field generator with a current that generates the changing magnetic field. The magnetic field generator may include one or more induction coils that generate the changing magnetic field, and the one or more induction coils may surround the sensor. In one embodiment, the aerosol generating device is capable of generating a changing magnetic field between 1 MHz and 30 MHz, for example, between 2 MHz and 10 MHz, or for example, between 5 MHz and 7 MHz. In one embodiment, the aerosol generating device is capable of generating a magnetic field with a field strength (H field) varying between 1 and 5 kA / m, for example between 2 kA / m and 3 kA / m, for example about 2.5 kA / m.

[0096] The receptor may include a metal or carbon. In one embodiment, the receptor may include a ferromagnetic material, such as ferritic, ferromagnetic steel, or stainless steel. In one embodiment, the receptor includes a nickel-iron alloy. In one embodiment, the receptor includes 400 series stainless steel, which includes grade 410, 420, or 430 stainless steel.

[0097] In some embodiments, the support component 12 includes a sensor 121, and the heating component 2 includes a magnetic field generator 21. Therefore, the heating component 2 can emit a changing magnetic field, causing the sensor 121 in the support component 12 to heat up. At least part of the heat generated by the sensor 121 in the support component 12 is used to heat the aerosol generation matrix layer 11, so that the aerosol generation matrix layer 11 generates aerosols.

[0098] Furthermore, the aerosol generation matrix layer 11 is disposed on the surface of the sensor 121 of the support component 12 so that the aerosol generation matrix layer 11 can absorb and utilize the heat generated by the sensor 121, which helps to reduce the power consumption of the heating component 2 and improve the energy utilization rate.

[0099] In some embodiments, the support component 12 includes a thermal conductor 121', and an aerosol generating matrix layer 11 is disposed on the surface of the thermal conductor 121' of the support component 2. The thermal 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 thermal conductors 121' include, but are not limited to: stainless steel, graphite, graphene, aluminum, copper, zinc, steel, silver, thermally conductive polymers, or any combination or alloy thereof.

[0100] In this embodiment, the heating component 2 may include a radiation light source 22.

[0101] The light emitted by the radiation source 22 can shine on the heat conductor 121', thereby heating the heat conductor 121' and increasing its temperature. Then, the heat conductor 121' releases heat to heat the aerosol generation matrix layer 11, causing the aerosol generation matrix layer 11 to generate aerosols.

[0102] Alternatively, the light emitted by the radiation source 22 can irradiate the aerosol generation matrix layer 11, thereby directly heating the aerosol generation matrix layer 11 and causing it to generate aerosols. Preferably, the aerosol generation matrix layer 11 is positioned facing the radiation source 22, and it can be located between the heat conductor 121' and the radiation source 22.

[0103] The heat conductor 121' has a high thermal conductivity, which helps to ensure that the aerosol generation matrix layer 11 disposed on its surface is heated uniformly.

[0104] In some embodiments, the aerosol generating matrix layer 11 is configured as a continuous ring along the circumference of the support component 12.

[0105] In some embodiments, referring to Figures 2-4, the sensor 121 or heat conductor 121' includes a tubular member 13, and the aerosol generating matrix layer 11 includes an annular matrix layer 112. The annular matrix layer 112 is disposed on the surface of the tubular member 13, and the annular matrix layer 112 extends in a continuous ring along the circumference of the tubular member 13.

[0106] As a typical example, the annular matrix layer 112 can be heated by the heating component 360° simultaneously, or the heating component 2 can heat the annular matrix layer 112 360° simultaneously.

[0107] Alternatively, as a typical example, the annular matrix layer 112 can be heated segment by segment or zone by zone by the heating component 2 in a preset order, so that the annular matrix layer 112 can generate aerosols segment by segment or zone by zone in a preset order.

[0108] In some embodiments, as shown in FIG5, the sensor 121 or heat conductor 121' includes a tubular member 13, and the aerosol generating matrix layer 11 includes a plurality of discrete matrix layers 111, which are disposed on the surface of the tubular member 13.

[0109] Multiple discrete matrix layers 111 are arranged in discrete rings along the circumference of the tubular member 13 at intervals. Alternatively, not shown, the multiple discrete matrix layers include multiple first discrete matrix layers and multiple second discrete matrix layers. The multiple first discrete matrix layers are arranged in discrete first rings along the circumference of the tubular member 13 at intervals, and the multiple second discrete matrix layers are arranged in discrete second rings along the circumference of the tubular member 13 at intervals. The first and second rings are arranged along the axial direction of the tubular member 13, and the first and second rings may be arranged along the same central axis as the tubular member 13. The first discrete matrix layers and the second discrete matrix layers are spaced apart axially.

[0110] In some embodiments, referring to Figures 6-13, the sensor 121 or heat conductor 121' includes a plurality of discrete components 14 spaced apart from each other. To ensure a defined positional relationship between the plurality of discrete components 14, the support assembly 12 further includes a tubular substrate 122, on which the plurality of discrete components 14 are held, and arranged in discrete rings along the circumference of the tubular substrate 122 at intervals from each other. The aerosol generating matrix layer 11 includes a plurality of discrete matrix layers 111, which are disposed one-to-one on the surfaces of the plurality of discrete components 14.

[0111] In some embodiments, the tubular substrate 122 is primarily made of an insulating material. The insulating material may include paper, such as cardboard. The insulating material may also include plastic materials, including but not limited to: PEEK, PI, PPS, PTFE, PA, PC, PMMA, and carbon fiber. The insulating material may also include inorganic materials, including but not limited to: ceramics, glass, or quartz. The insulating material may also include composite materials.

[0112] In some embodiments, the tubular substrate 122 includes a metallic material and an insulating layer disposed on the surface of the metallic material. The insulating layer may be an insulating coating, such as a glaze. The insulating layer may also be a metal oxide layer formed by the oxidation of the metallic material.

[0113] It should be noted that in some embodiments where the sensor 121 or heat conductor 121' includes a tubular member 13, as can be seen with reference to Figures 2-5, the support assembly 12 may also include a tubular base 122, and the tubular member 13 is held on the tubular base 122 and thus supported by the tubular base 122.

[0114] In some embodiments, the thermal conductivity of the tubular substrate 122 is less than that of the sensor 121 or the heat conductor 121'.

[0115] When the sensor 121 or heat conductor 121' includes a plurality of discrete components 14 spaced apart from each other, on the one hand, the spaced arrangement of two adjacent discrete components 14 results in a large thermal resistance between the two adjacent discrete components 14; on the other hand, the spaced arrangement of two adjacent discrete components 14 on a tubular substrate 122 with a small thermal conductivity helps to prevent heat from being transferred from one sensor 121 or heat conductor 121' to another sensor 121 or heat conductor 121', thereby reducing heat crosstalk between two adjacent sensor 121 or heat conductor 121'.

[0116] Furthermore, regardless of whether the sensor 121 or the heat conductor 121' includes multiple discrete components 14 spaced apart from each other, or whether the sensor 121 or the heat conductor 121' includes a tubular component 13, as long as the sensor 121 or the heat conductor 121' is held on a tubular substrate 122 with low thermal conductivity, it helps to increase the thermal resistance between the sensor 121 or the heat conductor 121' and the tubular substrate 122, thereby reducing the heat loss of the sensor 121 or the heat conductor 121' through the tubular substrate 122 and reducing the heat absorbed by the tubular substrate 122 from the sensor 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.

[0117] Furthermore, the thermal conductivity of the tubular substrate 122 is less than 10 W / (m•K). And / or, the specific heat capacity of the tubular substrate 122 is 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 substrate 122 with a higher specific heat capacity can effectively impede the rate at which heat is conducted through it, thereby helping to reduce thermal crosstalk between two adjacent sensor 121 or heat conductor 121'.

[0118] In some embodiments, the thickness of the sensor 121 or the heat conductor 121' is less than or equal to the thickness of the tubular substrate 122, thereby helping to reduce the heat consumed by the sensor 121 or the heat conductor 121' when it reaches the preset temperature, and helping to reduce the power consumption of the heating component 2 and improve the heating efficiency of the heating component 2.

[0119] The small thickness of the heat conductor 121' helps to quickly and evenly distribute heat on the heat conductor 121', and also allows the aerosol generation matrix layer 11 disposed on the heat conductor 121' to be heated evenly and quickly and generate aerosols.

[0120] The thickness D1 of the sensor 121 or the heat conductor 121' can satisfy: 0.02mm ≤ D1 ≤ 0.2mm. For example, D1 can be approximately equal to 0.1mm.

[0121] The tubular substrate 122 is used to support the sensor 121 or the heat conductor 121', so the tubular substrate 122 needs a certain stiffness. Preferably, the thickness D2 of the tubular substrate 122 satisfies: 0.05mm≤D2≤0.5mm. For example, D2 can be approximately equal to 0.1mm.

[0122] In some embodiments, referring to Figures 2-15, a window 1221 is provided on the tubular substrate 122. The sensor 121 or heat conductor 121' is held on the tubular substrate 122 and covers the window 1221, such that at least a portion of the sensor 121 or heat conductor 121' corresponds to the window 1221. This reduces the contact area between the sensor 121 or heat conductor 121' and the tubular substrate 122, helps to increase the thermal resistance between the sensor 121 or heat conductor 121' and the tubular substrate 122, and reduces the heat absorbed by the tubular substrate 122 from the sensor 121 or heat conductor 121'. Therefore, it can protect the tubular substrate 122 and prevent the tubular substrate 122 with low thermal conductivity and / or high specific heat capacity from being burned by the high temperature on the sensor 121 or heat conductor 121'. In some embodiments, when the tubular substrate 122 is made of paper, at least a partial corresponding window 1221 is provided for the sensor 121 or the heat conductor 121' to prevent the paper from being scorched and carbonized.

[0123] Preferably, the area of ​​the sensor 121 or the heat conductor 121' is slightly larger than the area of ​​the window 1221, so that the sensor 121 or the heat conductor 121' can be placed on the outside or inside of the tubular substrate 122 and can completely block the window 1221 to prevent aerosol from passing through the window 1221 and leaking.

[0124] Furthermore, the fact that the area of ​​the sensor 121 or the heat conductor 121' is larger than the area of ​​the window 1221 also helps to fix the sensor 121 or the heat conductor 121' to the tubular substrate 122 by means of adhesive, welding or fastening.

[0125] Of course, the sensor 121 or the heat conductor 121' can also be fixed to the tubular substrate 122 by insert injection molding.

[0126] In some embodiments, the ignition point or melting point of the sensor 121 or the heat conductor 121' is greater than the ignition point or melting point of the tubular substrate 122. This helps to expand the range of materials that can be selected for the tubular substrate 122 and reduce the manufacturing cost of the tubular substrate 122.

[0127] In some embodiments, referring to Figures 2-15, there are multiple windows 1221, and the multiple windows 1221 are arranged in discrete rings along the circumference of the tubular substrate 122 at intervals. Each window 1221 may be covered by a sensor 121 or a heat conductor 121', and / or each window 1221 may have an aerosol generation matrix layer 11 corresponding to it.

[0128] In the embodiments shown in Figures 4-13, the sensor 121 or heat conductor 121' includes a plurality of discrete components 14, which cover a plurality of windows 1221 in a one-to-one correspondence, and the surface of each discrete component 14 may be provided with a discrete matrix layer 111.

[0129] In the embodiments shown in Figures 2-5, the sensor 121 or heat conductor 121' includes a tubular member 13, which simultaneously covers multiple windows 1221, and an aerosol generation matrix layer 11 is disposed on the surface of the tubular member 13.

[0130] In some further embodiments, referring to Figures 2-4, the aerosol generating matrix layer 11 includes an annular matrix layer 112, which is disposed on the surface of the tubular member 13 and extends circumferentially along the tubular member 13 to form a continuous ring.

[0131] Alternatively, in some further embodiments, referring to FIG5, the aerosol generating matrix layer 11 includes a plurality of discrete matrix layers 111 spaced apart from each other. Each discrete matrix layer 111 is 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 primarily generate heat, or allows the radiation source 22 to primarily emit light corresponding to the window 1221.

[0132] 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.

[0133] In the embodiments shown in Figures 8 and 10, 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.

[0134] In some embodiments, referring to Figures 1, 7, 8, 13, and 14, the sensor 121 or the heat conductor 121 is disposed on the outer side or outer surface of the tubular substrate 122. In some embodiments, referring to Figures 3, 4, 9, 10, and 12, the sensor 121 or the heat conductor 121 is disposed on the inner side or inner surface of the tubular substrate 122.

[0135] In some embodiments, referring to Figures 11-13, the aerosol generation matrix layer 111 includes an inner aerosol generation matrix layer 113 and an outer aerosol generation matrix layer 114. The inner aerosol generation matrix layer 113 is disposed on the inner surface of the sensor 121 or the heat conductor 121', and the outer aerosol generation matrix layer 114 is disposed on the outer surface of the sensor 121 or the heat conductor 121'.

[0136] In some embodiments, the discrete matrix layer 111 includes an inner discrete matrix layer 111' and an outer discrete matrix layer 111''.

[0137] Example 1: Not shown, at least one inner discrete matrix layer 111' may be provided on the inner surface of the tubular member 13, and at least one outer discrete matrix layer 111'' may be provided on the outer surface of the tubular member 13.

[0138] Example 2: Referring to Figures 11-13, at least one inner discrete matrix layer 111' is provided on the inner surface of at least one discrete component 14, and at least one outer discrete matrix layer 111'' can be provided on the outer surface of the discrete component 14.

[0139] In some embodiments, not shown, the annular matrix layer 112 includes an inner annular matrix layer and an outer annular matrix layer. The inner annular matrix layer may be disposed on the inner surface of the tubular member 13, while the outer annular matrix layer may be disposed on the outer surface of the tubular structure 13.

[0140] It should be noted that when the aerosol-generating article 1 includes a tubular component 13, the tubular substrate 133 is optional rather than selected.

[0141] In some embodiments, as shown in FIG1, the aerosol generating apparatus 100 or the aerosol generating article 1 further includes a nozzle 3, which can be held in the mouth of a user, and the user can suck up the aerosol generated by the aerosol generating matrix layer 11 by sucking the nozzle 3.

[0142] When the aerosol generating article 1 includes a nozzle 3, when it is combined with the aerosol generating device 100, the nozzle 3 of the aerosol generating article 1 is exposed outside the aerosol generating device 100 for the user to hold in their mouth.

[0143] When the aerosol generating apparatus 100 includes a nozzle 3, the aerosol generating article 1 can be completely concealed inside the aerosol generating apparatus 100. Preferably, the aerosol generating apparatus 100 includes a nozzle 3.

[0144] In some embodiments, referring to FIG1, the aerosol generation system further includes an airflow channel 4, which connects the nozzle 3 and the aerosol generation matrix layer 11. The airflow channel 4 is used to guide the aerosol generated by the aerosol generation matrix layer 11 to the nozzle 3. Along the airflow direction, the nozzle 3 is located downstream of the aerosol generation matrix layer 11.

[0145] In some embodiments, referring to Figures 18 and 19, the heating assembly 2 includes a first heating assembly 23. When the aerosol generating article 1 is combined with the aerosol generating apparatus 100, the first heating assembly 23 is located inside the support assembly 12 and is thus surrounded by the support assembly 12. The first heating assembly 23 can heat the aerosol generating matrix layer 11 from the inside of the support assembly 12, causing the aerosol generating matrix layer 11 to generate aerosols.

[0146] When the aerosol generating matrix layer 11 is provided on the inner surface of the support component 12 (or the sensor 121 / heat conductor 121'), at least a portion of the airflow channel 4 is located between the inner surface of the support component 12 and the first heating component 23. Further, at least a portion of the airflow channel 4 may be located between the first heating component 23 and the aerosol generating matrix layer 11 disposed on the inner surface of the support component 12, thereby causing the first heating component 23 and the aerosol generating matrix layer 11 to be spaced apart.

[0147] When an aerosol generation matrix layer 11 is provided on the outer surface of the support component 12 (or the sensor 121 / heat conductor 121'), at least a portion of the airflow channel 4 is located outside the support component 12.

[0148] When the aerosol generation matrix layer 11 is present on both the outer and inner surfaces of the support component 12 (or the sensor 121 / heat conductor 121'), a portion of the airflow channel 4 is located on the outer side of the support component 12, and a portion of the airflow channel 4 is located on the inner side of the support component 12.

[0149] In some embodiments, referring to Figures 16 and 17, the heating component 2 includes a second heating component 24. When the aerosol generating article 1 is combined with the aerosol generating device 100, the second heating component 24 is located outside the support component, so that the second heating component 24 can heat the aerosol generating matrix layer 11 from the outside of the support component 12, so that the aerosol generating matrix layer 11 generates aerosol.

[0150] When the aerosol generating matrix layer 11 is provided on the outer surface of the support component 12 (or the sensor 121 / heat conductor 121'), at least a portion of the airflow channel 4 is located between the outer surface of the support component 12 and the second heating component 24. Further, at least a portion of the airflow channel 4 may be located between the second heating component 24 and the aerosol generating matrix layer 11 disposed on the outer surface of the support component 12, thereby causing the second heating component 24 and the aerosol generating matrix layer 11 to be spaced apart.

[0151] When the aerosol generation matrix layer 11 is provided on the inner surface of the support component 12 (or the sensor 121 / heat conductor 121), at least a portion of the airflow channel 4 is located inside the support component 12.

[0152] In some embodiments, the heating component 2 includes a first heating component 23 and a second heating component 24, which are located on opposite sides of the support component 12.

[0153] The first heating component 23 and the second heating component 24 can be the same heating component 2. For example, both the first heating component 23 and the second heating component 24 can include a magnetic field generator 21, or both the first heating component 23 and the second heating component 24 can include a radiation source 22. The first heating component 23 and the second heating component 24 can be different heating components. For example, one of the first heating component 23 and the second heating component 24 can include a magnetic field generator 21, and the other can include a radiation source 22.

[0154] When both a first heating component 23 and a second heating component 24 are present, the first heating component 23 and the second heating component 24 can be configured to work simultaneously or not at the same time.

[0155] In some embodiments, referring to Figures 16-21, the heating assembly 2 includes a radiation source 22 configured to emit light radially along the support assembly 12 to irradiate at least a portion of the aerosol generation matrix layer 11. Accordingly, the radiation source 22 may be located inside and / or outside the support assembly 12.

[0156] In some embodiments, referring to Figures 16 and 18, the illumination angle of the radiation source 22 in the circumferential direction of the support component 12 is less than 360°. Thus, the radiation source 22 cannot illuminate the annular matrix layer 112 in 360°, or simultaneously illuminate all discrete matrix layers 111 arranged in discrete annular shapes.

[0157] 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.

[0158] In the embodiments shown in Figures 2-13, 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 light 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.

[0159] Alternatively, in the embodiments shown in Figures 14 and 15, the support assembly 12 is configured 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.

[0160] 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°.

[0161] As another typical example, referring to Figures 17 and 19, there are multiple radiation light sources 22 arranged in discrete ring light sources. The multiple radiation light sources 22 are configured to emit light in a preset order to irradiate the aerosol generation matrix layer 11 in a preset order, thereby making full use of the aerosol generation matrix layer 11. This helps to ensure that the aerosol generation matrix layer 11 is fully irradiated by the light emitted by the radiation light sources 22 in the preset order, so that the aerosol generation matrix layer 11 can fully generate aerosols.

[0162] For example, multiple radiation sources 22 include multiple light-emitting diodes or laser diodes, which are arranged in a ring array. The diodes or diode groups (a diode group includes multiple diodes) in the array are controlled to emit light and extinguish in a preset order, so that the aerosol generation matrix layer 11 is irradiated by the light emitted by the radiation source 22 in a preset order.

[0163] Alternatively, for example, multiple radiation light sources 22 include multiple infrared coatings arranged in a ring, and the multiple infrared coatings are controlled to heat up sequentially in a preset order to radiate infrared light, so that the aerosol generation matrix layer is fully irradiated by the light emitted by the radiation light sources.

[0164] Alternatively, for example, multiple radiation sources 22 include annular infrared coatings, and different regions on the annular infrared coatings are controlled to heat up and radiate infrared light in a clockwise or counterclockwise direction in sequence, so that the aerosol generation matrix layer 11 is fully irradiated by the light emitted by the radiation sources 22 in a preset order.

[0165] Of course, multiple radiation sources 22 can also emit light simultaneously, thereby illuminating the support component 12 in 360°.

[0166] Multiple radiation sources 22 arranged in discrete ring shapes can be located inside the support assembly 12, thus being surrounded by the support assembly 12. Alternatively, multiple radiation sources 22 arranged in discrete ring shapes can be located outside the support assembly 12, thus surrounding the support assembly 12.

[0167] In some embodiments, the aerosol generating matrix layer 11 includes N discrete matrix layers 111, and the radiation source 22 has one or a group (a group of radiation sources 22 includes multiple radiation tubes 22), with one or a group of radiation sources 22 corresponding to a portion of the N discrete matrix layers 111. The aerosol generating article 1 is configured to rotate relative to the radiation source 22 M times, or the aerosol generating article 1 or the radiation source 22 is configured to rotate M times. Each time the aerosol generating article 1 or the radiation source 22 rotates, another portion of the N discrete matrix layers 111 replaces the original discrete matrix layer 111 corresponding to the radiation source 22. After the aerosol generating article 1 or the radiation source 22 rotates M-1 times, all N discrete matrix layers 111 have been irradiated by light emitted by the radiation source 22. After the aerosol generating article 1 or the radiation source 22 rotates M times, the aerosol generating article 1 or the radiation source 22 returns to its origin. Here, M and N are both integers greater than 1. M can be equal to N. M may not be equal to N.

[0168] In some embodiments, a plurality of radiation light sources 22 are arranged in a discrete ring along the circumference, and a plurality of discrete matrix layers 111 are arranged in a discrete ring along the circumference, with the plurality of radiation light sources 22 corresponding one-to-one with the plurality of discrete matrix layers 111. The plurality of radiation light sources 22 are configured to emit light sequentially in a clockwise or counterclockwise order, thereby irradiating the plurality of discrete matrix layers 111 sequentially.

[0169] In some embodiments, a plurality of radiation sources 22 are arranged in a discrete ring around the periphery, and the annular matrix layer 112 is located within the surrounding area of ​​the plurality of radiation sources 22, or the annular matrix layer 112 surrounds the plurality of radiation sources 22. The plurality of radiation sources 22 are configured to emit light sequentially in a clockwise or counterclockwise order, so that the area of ​​the annular matrix layer 112 is sequentially irradiated. Preferably, the plurality of radiation sources 22 are arranged in a uniformly distributed discrete ring.

[0170] In some embodiments, referring to Figures 20 and 21, the irradiation length of the radiation source 22 in the axial direction of the support component 12 is less than the axial extension length L of the aerosol generation matrix layer 11. Therefore, when the radiation source 22 emits light, a portion of the aerosol generation matrix layer 11 is located outside the illumination range in the axial direction.

[0171] As a typical example, the aerosol generating article 1 is configured to move relative to the radiation source 22 along the axial direction of the support assembly 12, so that the aerosol generating matrix layer 11 can be irradiated by the radiation source 22 in a preset sequence. This allows for full utilization of the aerosol generating matrix layer 11, and helps to ensure that the aerosol generating matrix layer 11 is fully irradiated by the light emitted by the radiation source 22, thereby enabling the aerosol generating matrix layer 11 to generate aerosols effectively.

[0172] The drive mechanism in the aerosol generating apparatus 100 can act on the positioning mechanism 1222 or the chamber, thereby driving the aerosol-generated article 1 to move axially relative to the radiation source 22. Alternatively, the drive mechanism in the aerosol generating apparatus 100 can act on the radiation source 22, thereby driving the radiation source 22 to move axially.

[0173] The radiation source 22 can be configured as a ring light source, positioned inside or outside the support component 12, allowing it to illuminate the support component 12 360°. Alternatively, multiple radiation sources 22 can be configured and arranged as discrete ring light sources, located inside or outside the support component 12, also illuminating it 360°. The driving mechanism then moves the support component 12 axially relative to the ring light sources or discrete ring light sources illuminating it 360°, ensuring that the aerosol generation matrix layer 11 is fully irradiated by the light emitted from the radiation sources 12 in a predetermined sequence.

[0174] As another typical example, referring to FIG21, there are multiple radiation light sources 22, which are arranged along the axial direction of the support assembly 12. The multiple radiation light sources 22 are configured to emit light in a preset order to irradiate the aerosol-generated matrix layer 111 in a preset order.

[0175] For example, multiple radiation sources 22 include multiple light-emitting diodes or laser diodes. These multiple diodes are arranged in a strip-shaped dot matrix along the axial direction of the support component. The diodes or diode groups (a diode group includes multiple diodes) in the dot matrix are controlled to emit light and extinguish in a preset order, so that the aerosol generation matrix layer 11 is fully irradiated by the light emitted by the radiation sources in a preset order.

[0176] Alternatively, for example, multiple radiation sources 22 may constitute multiple ring light sources or multiple discrete ring light sources. The multiple ring light sources and / or multiple discrete ring light sources are arranged along the axial direction of the support component 12. The multiple ring light sources and / or multiple discrete ring light sources are controlled to emit light and extinguish sequentially in one direction along the axial direction, so that the aerosol generation matrix layer 11 is fully irradiated by the light emitted by the radiation sources in a preset order.

[0177] Alternatively, for example, it may have multiple infrared coatings arranged along the axial direction of the support component, and these multiple infrared coatings heat up sequentially in a preset order to radiate infrared light, so that the aerosol generation matrix layer is fully irradiated by the light emitted by the radiation source.

[0178] Alternatively, for example, multiple radiation sources 22 include annular infrared coatings, on which different regions sequentially heat up and radiate infrared light in one axial direction, such that the aerosol generation matrix layer 11 is fully irradiated by the light emitted by the radiation sources in a predetermined order.

[0179] In some embodiments, when the heating component 2 includes a radiation light source 22, the support component 12 includes a heat conductor 121', and an aerosol generation matrix layer 11 is disposed on the surface of the heat conductor 121', with the heat conductor 121' and the radiation light source 22 located on opposite sides of the aerosol generation matrix layer 11. The heat conductor 121' can, on the one hand, maintain the aerosol generation matrix layer 11, and on the other hand, help to ensure uniform heating of the aerosol generation matrix layer 11. Simultaneously, it can also intercept the light emitted by the radiation light source 22, preventing the light emitted by the radiation light source 22 from passing through the window 1221 or the support component 12.

[0180] In some embodiments, the heating assembly 2 includes a magnetic field generator 21 for emitting a changing magnetic field, the support assembly 12 includes a sensor 121, and an aerosol generating matrix layer 11 is disposed on the surface of the sensor 121.

[0181] In some embodiments, the magnetic field coverage angle of the magnetic field generator 21 in the circumferential direction of the support component 12 is less than 360°. Therefore, the magnetic field emitted by the magnetic field generator 21 cannot cover the annular matrix layer 112 or the tubular receptor 121 360°, or simultaneously cover all discrete matrix layers 111 or discrete receptors 121 arranged in discrete annular shapes. It should be noted that the magnetic field not covering the receptor 121 or the aerosol generating matrix layer 11 means that the magnetic field strength in the uncovered areas of the receptor 121 or the aerosol generating matrix layer 11 is too low to cause the receptor 121 to generate heat that causes the corresponding aerosol generating matrix layer 11 to generate aerosols, while the magnetic field strength in the covered areas of the receptor 121 or the aerosol generating matrix layer 11 is high enough to cause the receptor 121 to generate heat that causes the corresponding aerosol generating matrix layer 11 to generate aerosols. Therefore, the sensor 121 in the area covered by the magnetic field emitted by the magnetic field generator 21 described in this application can generate heat to cause the aerosol generation matrix layer 11 corresponding to the sensor 121 to generate aerosols, and the remaining area is collectively referred to as the area not covered by the magnetic field emitted by the magnetic field generator 21.

[0182] As a typical example, the aerosol generating article 1 is configured to rotate relative to the magnetic field generator 21 so that the receptor 121 can be covered by the magnetic field emitted by the magnetic field generator 21 in a predetermined order. This allows for full utilization of the aerosol generating matrix layer 11, ensuring that the aerosol generating matrix layer 11 is adequately covered by the magnetic field emitted by the magnetic field generator 21, 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 generator 21. Preferably, the aerosol generating article 1 can rotate 360° relative to the generator 21.

[0183] The drive mechanism in the aerosol generating device 100 can act on the positioning mechanism 1222 or the chamber, thereby driving the aerosol generating product 1 to rotate relative to the magnetic field generator 21.

[0184] Alternatively, the magnetic field generator 21 is configured to be rotatable, and the rotation of the magnetic field generator 21 causes the magnetic fields emitted by the magnetic field generator 21 in a preset sequence to cover the aerosol generation matrix layer 11 and the receptor 121. For example, the drive mechanism in the aerosol generation apparatus 100 can act on the magnetic field generator 21, thereby driving the magnetic field generator 21 to rotate relative to the aerosol generation article 1. For example, the magnetic field generator 21 can be configured to rotate at least 270°. Preferably, the magnetic field generator 21 can rotate 360°.

[0185] As another typical example, referring to Figures 17 and 19, the magnetic field generator 21 has multiple units, which are arranged in discrete rings. The multiple magnetic field generators 21 are configured to operate in a preset order so that the magnetic field covers the aerosol generation matrix layer 11 and the receptor 121 in the preset order.

[0186] Multiple magnetic field generators 21 are arranged in discrete rings and can be located inside the support assembly 12, thus being surrounded by the support assembly 12. Multiple magnetic field generators 21 are also arranged in discrete rings and can be located outside the support assembly 12, thus surrounding the support assembly 12.

[0187] Of course, multiple magnetic field generators 21 can also emit magnetic fields simultaneously, so that the magnetic field can cover the support component 12 360°.

[0188] In some embodiments, the aerosol generating matrix layer 11 includes N discrete matrix layers 111, and the magnetic field generator 21 has one or a group (a group of magnetic field generators 21 includes multiple magnetic field generators 21), with one or a group of magnetic field generators 21 corresponding to a portion of the N discrete matrix layers 111. The aerosol generating article 1 is configured to rotate M times relative to the magnetic field generator 21, or the aerosol generating article 1 or the magnetic field generator 21 is configured to rotate M times. Each time the aerosol generating article 1 or the magnetic field generator 21 rotates, another portion of the N discrete matrix layers 111 replaces the original discrete matrix layer 111 corresponding to the magnetic field generator 21. After the aerosol generating article 1 or the magnetic field generator 21 rotates M-1 times, all N discrete matrix layers 111 are covered by the magnetic field emitted by the radiation source 22. After the aerosol generating article 1 or the magnetic field generator 21 rotates M times, the aerosol generating article 1 or the magnetic field generator 21 returns to its original position. Where M and N are both integers greater than 1. M can be equal to N. M can not be equal to N.

[0189] In some embodiments, a plurality of magnetic field generators 21 are arranged in a discrete ring along the circumference, and a plurality of discrete matrix layers 111 are arranged in a discrete ring along the circumference, with the plurality of magnetic field generators 21 corresponding one-to-one with the plurality of discrete matrix layers 111. The plurality of magnetic field generators 21 are configured to emit magnetic fields sequentially in a clockwise or counterclockwise order, thereby causing the plurality of discrete matrix layers 111 to be sequentially covered by magnetic fields.

[0190] 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.

[0191] In some embodiments, referring to Figures 20 and 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. Thus, 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] As another typical example, referring to FIG21, the magnetic field generator 21 has multiple magnetic field generators 21 arranged along the axial direction of the support assembly 12. The multiple magnetic field generators 21 are configured to operate in a preset order so that the magnetic field covers the sensor 121 in the preset order.

[0196] For example, a plurality of induction coils are arranged along the axial direction of the support assembly 12, and the induction coils in the plurality of induction coils are controlled to emit magnetic fields in a preset order, so that the sensor 121 can be covered by the magnetic field in the preset order in the axial direction.

[0197] Alternatively, for example, multiple magnetic field generators 21 may include multiple spiral induction coils or multiple disc induction coils, which are arranged along the axial direction of the support assembly 12. The multiple spiral induction coils or multiple disc induction coils are controlled to emit magnetic fields sequentially in one direction along the axial direction, so that the sensor 121 can be covered by the magnetic field in a preset order along the axial direction.

[0198] In some embodiments, the heating component 2 is spaced apart from the aerosol generating matrix layer 11 to prevent wear of the aerosol generating matrix layer 11 when the aerosol generating article 1 is joined with the aerosol generating device 100, or to prevent residue on the aerosol generating matrix layer 11 from adhering to the heating component 2 when the aerosol generating article 1 is removed from the aerosol generating device 100.

[0199] In some embodiments, the heating component 2 is spaced apart from the sensor 121 or the heat conductor 121'. This is to prevent wear on the heating component 2 when the aerosol generating article 1 is combined with the aerosol generating device 100, or to reduce the conduction of heat from the sensor 121 to the magnetic field generator 21 when the sensor 121 heats up.

[0211] 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.

[0212] If desired, the aerosol generating matrix layer may contain additional tobacco or non-tobacco volatile flavor compounds released when the aerosol generating matrix layer is heated. The aerosol generating matrix layer may also contain microcapsules, such as those containing additional tobacco or non-tobacco volatile flavor compounds, and these microcapsules may melt during heating of the solid aerosol generating matrix layer.

[0213] Preferably, the aerosol-generating matrix layer 11 is a tobacco sheet comprising tobacco material, fibers, binders, and an aerosol forming agent. Preferably, the tobacco sheet is a cast leaf. A cast leaf is a form of reconstituted tobacco formed from a pulp comprising tobacco particles, fiber particles, an aerosol forming agent, a binder, and, for example, a flavoring agent.

[0214] The tobacco particles may be in the form of tobacco dust having particles of about 30 micrometers to 250 micrometers, preferably about 30 micrometers to 80 micrometers or 100 micrometers to 250 micrometers, depending on the desired sheet thickness and the casting gap, wherein the casting gap typically defines the sheet thickness.

Fiber pellets may be selected based on the need for sufficient tensile strength to produce sheets and a low inclusion rate, for example, an inclusion rate between about 2% and 15%. Alternatively, fibers such as plant fibers may be used in conjunction with the aforementioned fiber pellets.
