[0002] At present, the portable aerosol products on the market mainly adopt bottom heating. Specifically, the heat generated by the heat source at the bottom of the product is transferred to the medium to generate aerosol. The bottom heating of the product has the following problems. On the one hand, since the heat source is fixed at the bottom, the medium close to the heat source is repeatedly heated, which affects the taste and consistency of the user's suction; on the other hand, since the medium has poor heat conduction performance, the medium far from the heat source cannot be fully heated, resulting in low utilization rate of the medium.

DETAILED DESCRIPTION

[0039] Further scope of applicability of the present application will become apparent from the detailed description given hereinafter. However, it should be understood that the description and specific embodiments discussed hereinafter are intended for purposes of illustration only and are not intended to limit the scope of the present application. Embodiments of the present application will be described herein below with reference to the accompanying drawings. In the drawings, like reference numerals indicate like elements or components throughout the several views. In addition, the embodiments of the present application described below are merely exemplary and are not intended to limit the present application.

[0040] In the present application, unless explicitly defined and limited otherwise, a first feature is "on" or "under" a second feature can mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature "over", "above" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. The first feature "under", "below" and "underneath" the second feature can mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is horizontally lower than the second feature.

[0041] Referring to Figure 1 and Figure 2 , embodiments of the present application provide an aerosol generating device 100. The aerosol generating device 100 includes an aerosol generating article 10 and a heating initiation assembly 20. The heating initiation assembly 20 is configured to provide an initiation heat source for the aerosol generating article 10.

[0042] Specifically, the aerosol generating article 10 and the heating initiation assembly 20 can each have a cylindrical structure. The aerosol generating article 10 has a smaller diameter than the heating initiation assembly 20, and is disposed on top of the heating initiation assembly 20. The aerosol generating device 100, for example, is an electronic cigarette that can be used as a substitute for a conventional combustible cigarette. When the aerosol generating device 100 is in operation, the heating initiation assembly 20 provides an initiation heat source for the aerosol generating article 10, and the aerosol generating article 10 generates an aerosol for a user to inhale after being heated by the initiation heat source. The heating initiation assembly 20 includes, but is not limited to, a flame, an electric resistance, microwaves, electromagnetic waves, a laser, and the like.

[0043] Referring to Figure 3 , embodiments of the present application provide an aerosol generating article 10. The aerosol generating article 10 includes a medium layer 11 and a heating layer 13 disposed around the medium layer 11. The medium layer 11 is configured to generate an aerosol when heated. Please refer to Figure 4 and Figure 5 , the heating layer 13 includes a substrate 131 and an exothermic material 132 disposed on the substrate 131. The substrate 131 includes a load area 1311. The exothermic material 132 is located in the load area 1311 and is configured to generate heat required to heat the medium layer 11.

[0044] In the aerosol generating article 10 of this application embodiment, the substrate 131 includes a supporting region 1311, and the exothermic material 132 is located in the supporting region 1311. When the aerosol generating article 10 is heated, the heating reaction will slowly advance along the supporting region 1311 to achieve propulsive heating. On the one hand, it can effectively avoid the nearby medium layer 11 from being repeatedly heated, thereby improving the product's taste and consistency; on the other hand, it can prevent the distant medium layer 11 from not being fully heated, thereby improving the medium utilization rate.

[0045] Please refer to it again. Figure 3 In the embodiments of this application, the aerosol generating article 10 includes a medium section 10a and a filtration and cooling section 10b. The aforementioned medium layer 11 and heating layer 13 are both located in the medium section 10a, or in other words, the medium section 10a includes the medium layer 11 and the heating layer 13. The filtration and cooling section 10b is used to filter and cool the aerosol generated in the medium section 10a.

[0046] Specifically, the medium section 10a and the filtration and cooling section 10b are arranged along the direction from bottom to top of the aerosol generating article 10 (i.e., along the axial direction of the aerosol generating article 10). The bottom of the aerosol generating article 10 is the end of the aerosol generating article 10 closest to the heating start-up component 20. The medium section 10a is used to generate aerosol when heated, and the filtration and cooling section 10b is used to reduce the temperature of the aerosol and filter impurities inside the aerosol, so that the temperature is suitable and the taste is better when the user inhales. The medium section 10a and the filtration and cooling section 10b can also be cylindrical structures. The diameters of the medium section 10a and the filtration and cooling section 10b are equal, so that the overall outer contour of the aerosol generating article 10 formed by the medium section 10a and the filtration and cooling section 10b is relatively smooth and continuous, resulting in a better user experience.

[0047] Please see Figure 3 The aerosol generating article 10 (specifically, the medium segment 10a) may include a medium layer 11, a temperature control layer 12, a heating layer 13, and a heat insulation layer 14. That is to say, the medium segment 10a is a sandwich structure. The medium layer 11, the temperature control layer 12, the heating layer 13, and the heat insulation layer 14 may be arranged sequentially from the inside to the outside along the radial direction of the medium layer 11.

[0048] The medium layer 11 is used to generate aerosols when heated. The medium layer 11 may have a cylindrical structure. The medium layer 11 contains plant materials or compounds that can release aerosols when heated. The plant materials include, but are not limited to, tobacco, medicinal herbs, spices, etc. The compounds include, but are not limited to, volatile compounds containing nicotine.

[0049] The diameter of the dielectric layer 11 can range from 3mm to 5mm. This smaller diameter allows the dielectric layer 11 to be heated more effectively, improving dielectric utilization. The length of the dielectric layer 11 can range from 10mm to 50mm. This reasonable length setting helps ensure the effectiveness of the propulsive heating. Furthermore, the combination of the diameter and length ranges of the dielectric layer 11 allows for a more reasonable overall volume, enabling the generation of a sufficient amount of aerosol.

[0050] A temperature control layer 12 is located between the dielectric layer 11 and the heating layer 13. The temperature control layer 12 may be cylindrical and surrounds the dielectric layer 11. By changing the heat transfer performance of the temperature control layer 12, the heating temperature of the dielectric layer 11 can be controlled. In this embodiment, the temperature control layer 12 is used to control the heating temperature of the dielectric layer 11 between 250°C and 350°C, so that the heating temperature of the dielectric layer 11 is more suitable. The thickness of the temperature control layer 12 may be less than or equal to 2 mm, so that the diameter of the entire dielectric section 10a is smaller. There are two methods for temperature control of the temperature control layer 12: one is to use a high thermal conductivity material to evenly distribute heat; the other is to use a low thermal conductivity material to increase thermal resistance or store heat to control heat transfer. When the temperature control layer 12 uses a high thermal conductivity material, the material of the temperature control layer 12 may include materials such as aluminum foil. When the temperature control layer 12 uses a low thermal conductivity material, the material of the temperature control layer 12 may include at least one of carbon fiber, ceramic fiber, pre-oxidized fiber, or other heat-resistant materials.

[0051] The heating layer 13 is located between the temperature control layer 12 and the heat insulation layer 14. The heating layer 13 may be cylindrical and is disposed around the dielectric layer 11. The aforementioned heating start-up component 20 provides a start-up heat source for the aerosol generation product 10, specifically providing a start-up heat source for the heating layer 13 to initiate the exothermic reaction of the heating layer 13. The thickness of the heating layer 13 may range from 0.2 mm to 1 mm, so that the diameter of the entire dielectric section 10a is small while providing sufficient heat.

[0052] Please see Figure 4 and Figure 5 The heating layer 13 includes a substrate 131 and a heat-dissipating material 132 disposed on the substrate 131. The substrate 131 includes a supporting region 1311 and a plurality of blank regions 1322, which are separated by the supporting region 1311. The heat-dissipating material 132 is located in the supporting region 1311 and is used to generate the heat required for the heating medium layer 11.

[0053] Specifically, the heating layer 13 generates heat through the oxidation of the heat-releasing material 132 to heat the dielectric layer 11. The heat-releasing material 132 can be disposed on the side of the substrate 131 facing the dielectric layer 11, so that the heat generated by the heat-releasing material 132 can be more easily transferred to the dielectric layer 11 through the temperature control layer 12. The heat-releasing material 132 can be a metallic or non-metallic material. Metallic materials include, but are not limited to, magnesium, aluminum, iron, etc., and non-metallic materials include, but are not limited to, carbon, etc. All of the above materials can generate heat after oxidation, thereby heating the dielectric layer 11.

[0054] Please continue reading. Figure 4 and Figure 5 The substrate 131 can be divided into a supporting region 1311 and multiple blank regions 1322. The multiple blank regions 1322 are separated by the supporting region 1311, while the exothermic material 132 is located within the supporting region 1311. When the aerosol-generating product 10 is heated, the heating reaction slowly propagates along the supporting region 1311, similar to the smoldering of sandalwood or mosquito coils, thus achieving progressive heating. On one hand, the heat source can advance over time without repeatedly heating the medium layer 11, thereby improving the product's taste and consistency; on the other hand, the advancement of the heat source allows for more thorough heating of the medium layer 11, thereby improving the medium utilization rate.

[0055] In this embodiment, the substrate 131 serves to support the exothermic material 132. Since the exothermic material 132 has a high oxidation exothermic temperature, the substrate 131 can be made of at least one of carbon fiber, pre-oxidized fiber, ceramic fiber, quartz fiber, or other heat-resistant materials to achieve good temperature resistance. The area of ​​the supporting region 1311 within the substrate 131 can range from 20% to 70%. That is, the area of ​​the exothermic material 132 within the substrate 131 ranges from 20% to 70%. This ensures the utilization rate of the substrate 131's area while also guaranteeing a certain amount of blank area 1322 to facilitate push-type heating.

[0056] Please see Figure 4 to Figure 7 In one embodiment, the bearing region 1311 includes a heating activation region 13111 and a plurality of heating extension regions 13112 extending from and dispersedly disposed within the self-heating activation region 13111. The plurality of heating extension regions 13112 are distributed in a stripe pattern on the substrate 131 relative to the heating activation region 13111. The dispersed arrangement of the plurality of heating extension regions 13112 is, for example, such that the plurality of heating extension regions 13112 are spaced apart from each other (e.g., ...). Figure 5 As shown, it is not a single structure.

[0057] Specifically, the heating activation region 13111 may be located on the substrate 131 near the end of the heating activation assembly 20. Multiple heating extension regions 13112 extend from the same side of the heating activation region 13111 (e.g., ...). Figure 4 to Figure 7In this process, multiple heating extension regions 13112 extend downward from the heating start-up region 13111. When the heating start-up component 20 provides a starting heat source for the aerosol generating article 10, the heating start-up component 20 provides a starting heat source at the heating start-up region 13111, so that the exothermic material 132 located in the heating start-up region 13111 oxidizes to generate heat, and then gradually advances the heating to each heating extension region 13112, and reacts fully.

[0058] Multiple heating extension regions 13112 are arranged in parallel and spaced apart to provide reaction intervals for the exothermic material 132 (similar to the smoldering of sandalwood or mosquito coils). The multiple heating extension regions 13112 are of equal length and are also equally spaced to ensure that the exothermic material 132 is evenly distributed and that the heating progress along the multiple heating extension regions 13112 after the heating start-up region 13111 is relatively even.

[0059] Furthermore, such as Figure 4 and Figure 5 As shown, multiple heating extension regions 13112 can all be perpendicular to the heating start-up region 13111 (i.e., distributed as straight stripes). In this case, the blank regions 1322, complementary to the heating start-up region 13111 and the multiple heating extension regions 13112, can have a square structure, such as a rectangle, and be evenly spaced, making the manufacturing process relatively simple. Alternatively, as... Figure 6 and Figure 7 As shown, the multiple heating extension regions 13112 can all be inclined relative to the heating start region 13111 (i.e., diagonal stripe distribution, for example, with an inclination angle of 40 degrees, 50 degrees, 60 degrees, 70 degrees, etc., which are not limited here). At this time, the blank region 1322, which is complementary to the heating start region 13111 and the multiple heating extension regions 13112, can be a parallelogram structure and is evenly distributed. The effective length of the heating extension regions 13112 is relatively long, which is beneficial to extending the heating time.

[0060] Both of the above-mentioned striped distribution structures can achieve propulsive heating. Since the oxidation reaction of the heating layer 13 is usually at a high temperature (400℃~600℃), the heat source is dispersed by using a striped distribution structure. The heating intensity and time can be designed by changing the pattern and length of the bearing area 1311 (that is, changing the pattern and length of the distribution of the heat-releasing material 132).

[0061] Please see Figure 8 and Figure 9In one embodiment, the bearing region 1311 includes a heating activation region 13111 and heating extension regions 13112 extending from and dispersedly disposed within the self-heating activation region 13111. The heating activation region 13111 and the heating extension regions 13112 are distributed in a grid pattern on the substrate 131. The dispersed arrangement of the heating extension regions 13112 is, for example, such that there are grid gaps between the heating extension regions 13112 (e.g.,...). Figure 9 As shown, it is not a single structure.

[0062] Specifically, the heating activation area 13111 may be located at the end of the substrate 131 near the heating activation assembly 20. For example... Figure 8 and Figure 9 As shown, either the upper or lower end of the substrate 131 can serve as the heating start-up region 13111. When the heating start-up component 20 provides a starting heat source for the aerosol-generating article 10, the heating start-up component 20 provides a starting heat source at the heating start-up region 13111, causing the exothermic material 132 located in the heating start-up region 13111 to oxidize and generate heat, and then gradually advances the heating to the heating extension region 13112, where a full reaction occurs. At this time, the blank region 1322, which is complementary to the heating start-up region 13111 and the multiple heating extension regions 13112, can be a square structure, such as a rectangular structure, and is distributed in a matrix, making the manufacturing process relatively simple.

[0063] It should be noted that the style of the bearing area 1311 is not limited to the above-mentioned forms. It can be designed according to the required heating intensity and heating time to ensure that propulsion heating is achieved.

[0064] Please see Figure 3 A heat insulation layer 14 is disposed on the side of the heating layer 13 facing away from the medium layer 11. The heat insulation layer 14 may be cylindrical and is disposed around the heating layer 13. The heat insulation layer 14 is used to reduce the surface temperature of the aerosol generating device 100. The thickness of the heat insulation layer 14 may range from 0.2 mm to 2 mm, so that the diameter of the entire medium section 10a is small and it can have a good heat insulation effect. The heat insulation layer 14 may be formed using a papermaking process. The material of the heat insulation layer 14 may be a non-metallic material with low thermal conductivity, such as carbon fiber, pre-oxidized fiber, ceramic fiber, quartz fiber, or at least one of other heat-resistant materials, to have a good heat insulation effect.

[0065] The top and bottom of the aforementioned medium layer 11, temperature control layer 12, heating layer 13 and heat insulation layer 14 can be flush to facilitate connection with the filter cooling section 10b and the heating start-up component 20, respectively.

[0066] In summary, in the aerosol generating article 10 and aerosol generating apparatus 100 of this application, the substrate 131 includes a supporting region 1311, and the exothermic material 132 is located in the supporting region 1311. When the aerosol generating article 10 is heated and started, the heating reaction will slowly advance along the supporting region 1311, realizing propulsive heating. On the one hand, it can effectively avoid the nearby medium layer 11 from being repeatedly heated, thereby improving the product's taste and consistency; on the other hand, it can prevent the distant medium layer 11 from not being fully heated, thereby improving the medium utilization rate.
