DETAILED DESCRIPTION

[0039] The following is a further description of the embodiments of the present application in conjunction with the accompanying drawings. The same or similar reference numerals in the accompanying drawings represent the same or similar elements or elements with the same or similar functions from beginning to end. In addition, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the present application.

[0040] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may 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, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] See also Figure 1 and Figure 2 The embodiment of the present application provides an aerosol generating device 100. The aerosol generating device 100 includes an aerosol generating article 10 and a heat-starting component 20. The heat-starting component 20 is used to provide a starting heat source for the aerosol generating article 10.

[0042] Specifically, the aerosol generating product 10 and the heating start component 20 can both be cylindrical structures. The diameter of the aerosol generating product 10 is smaller than the diameter of the heating start component 20, and the aerosol generating product 10 is arranged on the top of the heating start component 20. The aerosol generating device 100 is, for example, an electronic cigarette, which can be used as a substitute for traditional combustible cigarettes. When the aerosol generating device 100 is working, the heating start component 20 provides a starting heat source for the aerosol generating product 10, and the aerosol generating product 10 generates aerosol for the user to inhale after heating and starting. The heating start component 20 includes, but is not limited to, heating equipment such as open flame, resistance, microwave, electromagnetic, laser, etc.

[0043] See also Figure 3 The embodiment of the present application provides 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 used to generate aerosol when heated. Figure 4 and Figure 5 The heating layer 13 includes a substrate 131 and a heat release material 132 disposed on the substrate 131. The substrate 131 includes a bearing region 1311. The heat release material 132 is located in the bearing region 1311 and is used to generate heat required for heating the medium layer 11.

[0044] In the aerosol generating product 10 of the embodiment of the present application, the substrate 131 includes a bearing area 1311, and the exothermic material 132 is located in the bearing area 1311. When the aerosol generating product 10 is heated and started, the heating reaction will slowly advance along the bearing area 1311, thereby realizing push-type heating. On the one hand, it can effectively prevent the nearby medium layer 11 from being heated repeatedly, thereby improving the taste and consistency of the product; on the other hand, it can prevent the distant medium layer 11 from being insufficiently heated, thereby improving the medium utilization rate.

[0045] Please refer again Figure 3 In the embodiment of the present application, the aerosol generating article 10 includes a medium section 10a and a filtering and cooling section 10b. The aforementioned medium layer 11 and the 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 filtering and cooling section 10b is used to filter and cool the aerosol generated by the medium section 10a.

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

[0047] See also 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 insulating layer 14. That is, the medium segment 10a is a sandwich structure. The medium layer 11, the temperature control layer 12, the heating layer 13 and the heat insulating layer 14 may be arranged in sequence from the inside to the outside along the radial direction of the medium layer 11.

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

[0049] The diameter of the medium layer 11 may range from 3 mm to 5 mm. In this way, the diameter of the medium layer 11 is small, and the medium layer 11 is easier to be fully heated, which is conducive to improving the medium utilization rate. The length of the medium layer 11 may range from 10 mm to 50 mm. In this way, the length of the medium layer 11 is set more reasonably, which is conducive to ensuring the effect of push-type heating. In addition, by matching the diameter range and length range of the medium layer 11, the overall volume of the medium layer 11 can also be made more reasonable, so as to generate a sufficient amount of aerosol.

[0050] The temperature control layer 12 is located between the medium layer 11 and the heating layer 13. The temperature control layer 12 may be cylindrical, and the temperature control layer 12 is arranged around the medium layer 11. By changing the heat transfer performance of the temperature control layer 12, the heating temperature of the medium layer 11 can be controlled. In the embodiment of the present application, the temperature control layer 12 is used to control the heating temperature of the medium layer 11 at 250°C to 350°C, so that the heating temperature of the medium layer 11 is more appropriate. The thickness of the temperature control layer 12 may be less than or equal to 2mm, so that the diameter of the entire medium section 10a is smaller. There are two ways to control the temperature 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 heat storage 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 wire or other temperature-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 the heating layer 13 is arranged around the medium layer 11. The aforementioned heating start component 20 provides a start heat source for the aerosol generating product 10, specifically, provides a start heat source for the heating layer 13 to start 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 medium segment 10a is small and sufficient heat can be provided.

[0052] See also 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 bearing area 1311 and a plurality of blank areas 1322, and the plurality of blank areas 1322 are separated by the bearing area 1311. The exothermic material 132 is located in the bearing area 1311 and is used to generate heat required for heating the medium layer 11.

[0053] Specifically, the heating layer 13 generates heat by oxidizing the exothermic material 132 to heat the dielectric layer 11. The exothermic material 132 can be disposed on the side of the substrate 131 facing the dielectric layer 11, so that the heat generated by the exothermic material 132 can be more conveniently transferred to the dielectric layer 11 through the temperature control layer 12. The exothermic material 132 can be made of metal material or non-metal material. Metal materials include but are not limited to magnesium, aluminum, iron, etc., and non-metal 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 as a whole can be divided into a bearing area 1311 and a plurality of blank areas 1322. The plurality of blank areas 1322 are separated by the bearing area 1311, and the exothermic material 132 is located in the bearing area 1311. When the aerosol generating product 10 is heated and started, the heating reaction will slowly advance along the bearing area 1311, similar to the smoldering of sandalwood and mosquito coils, thereby achieving propulsive heating. On the one hand, the heat source can be advanced over time, and the medium layer 11 will not be repeatedly heated, thereby improving the taste and consistency of the product; on the other hand, the heat source advancement can make the medium layer 11 more fully heated, thereby improving the medium utilization rate.

[0055] In the embodiment of the present application, the function of the substrate 131 is to carry 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 silk, ceramic fiber, quartz fiber or other temperature-resistant materials to have good temperature resistance. The area of ​​the bearing area 1311 in the substrate 131 can be in the range of 20% to 70%. In other words, the area of ​​the exothermic material 132 in the substrate 131 is in the range of 20% to 70%. In this way, the utilization rate of the use area of ​​the substrate 131 can be ensured, and a certain blank area 1322 can also be ensured to facilitate push-type heating.

[0056] See also Figures 4 to 7 In one embodiment, the support area 1311 includes a heating start area 13111 and a plurality of heating extension areas 13112 extending from the heating start area 13111 and arranged in a dispersed manner. The plurality of heating extension areas 13112 are distributed on the substrate 131 in a stripe shape relative to the heating start area 13111. The plurality of heating extension areas 13112 are arranged in a dispersed manner, for example, the plurality of heating extension areas 13112 are spaced apart from each other (e.g., Figure 5 As shown, it is not a complete structure).

[0057] Specifically, the heating activation region 13111 may be located at the end of the substrate 131 near the heating activation component 20. A plurality of heating extension regions 13112 extend from the same side of the heating activation region 13111 (eg, Figures 4 to 7In the embodiment of the present invention, the plurality of heating extension regions 13112 all extend downward from the heating activation region 13111). When the heating activation component 20 provides a startup heat source for the aerosol generating article 10, the heating activation component 20 provides a startup heat source at the heating activation region 13111, so that the exothermic material 132 located in the heating activation region 13111 is oxidized to generate heat, and then gradually heated to each heating extension region 13112 and fully reacts.

[0058] The plurality of heating extension areas 13112 are arranged in parallel and spaced apart to provide reaction spacing gaps (similar to the smoldering of sandalwood and mosquito coils) for the exothermic material 132. The lengths of the plurality of heating extension areas 13112 are equal and the spacing between them is also equal, so that the exothermic material 132 is evenly distributed, and the heating advancement along the plurality of heating extension areas 13112 after the heating start area 13111 is also relatively balanced.

[0059] Furthermore, if Figure 4 and Figure 5 As shown, the plurality of heating extension areas 13112 may be perpendicular to the heating activation area 13111 (i.e., arranged in straight stripes). In this case, the blank area 1322 complementary to the heating activation area 13111 and the plurality of heating extension areas 13112 may be a square structure, such as a rectangular structure, and may be evenly spaced, and the manufacturing process is relatively simple. Alternatively, Figure 6 and Figure 7 As shown, the multiple heating extension areas 13112 can be inclined relative to the heating start area 13111 (i.e., distributed in oblique stripes, for example, the inclination angle is 40 degrees, 50 degrees, 60 degrees, 70 degrees, etc., which is not limited here). At this time, the blank area 1322 complementary to the heating start area 13111 and the multiple heating extension areas 13112 can be a parallelogram structure and distributed at equal intervals. The effective length of the heating extension area 13112 is longer, which is conducive to extending the heating time.

[0060] Both of the above-mentioned stripe-shaped distribution structures can realize push-type heating. Since the oxidation reaction of the heating layer 13 is usually at a high temperature (400°C to 600°C), a stripe-shaped distribution structure is used to disperse the heat source, and the intensity and time of heating can be designed by changing the style and length of the bearing area 1311 (that is, changing the style and length of the heat release material 132 distribution).

[0061] See also Figure 8 and Fig. 9In one embodiment, the bearing area 1311 includes a heating start area 13111 and a heating extension area 13112 extending from the heating start area 13111 and arranged in a dispersed manner. The heating start area 13111 and the heating extension area 13112 are distributed in a grid shape on the substrate 131. The heating extension area 13112 is dispersedly arranged, for example, there is a grid gap in the middle of the heating extension area 13112 (such as Fig. 9 As shown, it is not a complete structure)

[0062] Specifically, the heating start area 13111 may be located at the end of the substrate 131 close to the heating start component 20. Figure 8 and Fig. 9 As shown, the upper end or the lower end of the substrate 131 can be used as the heating start area 13111. When the heating start component 20 provides a starting heat source for the aerosol generating article 10, the heating start component 20 provides a starting heat source at the heating start area 13111, so that the exothermic material 132 located in the heating start area 13111 is oxidized to generate heat, and then gradually advances to heat the heating extension area 13112 and fully reacts. At this time, the blank area 1322 complementary to the heating start area 13111 and the plurality of heating extension areas 13112 can be a square structure, such as a rectangular structure, and is distributed in a matrix, and the manufacturing process is also relatively simple.

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

[0064] See also Figure 3 , the heat insulation layer 14 is arranged on the side of the heating layer 13 facing away from the medium layer 11. The heat insulation layer 14 can be cylindrical, and the heat insulation layer 14 is arranged 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 can range from 0.2 mm to 2 mm, so that the diameter of the entire medium section 10a is small and can have a better heat insulation effect. The heat insulation layer 14 can be formed by a papermaking process. The material of the heat insulation layer 14 can be selected from non-metallic materials with low thermal conductivity, such as carbon fiber, pre-oxidized silk, ceramic fiber, quartz fiber or at least one of other temperature-resistant materials, so as to have a better heat insulation effect.

[0065] The tops and bottoms of the medium layer 11, the temperature control layer 12, the heating layer 13 and the heat insulation layer 14 can be arranged flush with each other so as to be connected to the filtering and cooling section 10b and the heating start component 20 respectively.

[0066] In summary, in the aerosol generating product 10 and the aerosol generating device 100 of the embodiment of the present application, the substrate 131 includes a bearing area 1311, and the exothermic material 132 is located in the bearing area 1311. When the aerosol generating product 10 is heated and started, the heating reaction will slowly advance along the bearing area 1311 to achieve push-type heating. On the one hand, it can effectively prevent the nearby medium layer 11 from being heated repeatedly, thereby improving the taste and consistency of the product; on the other hand, it can prevent the distant medium layer 11 from being insufficiently heated, thereby improving the medium utilization rate.
