Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and in particular to an aerosol generating product. Background Art

[0002] Heat-not-burn aerosol-generating substrates utilize a special heat source to generate aerosols, a novel atomizing medium that utilizes a special heat source. During heating, the various substances within them evaporate to produce an aerosol, meeting user needs. Heat-not-burn aerosol-generating substrates produce no open flames during use, making them environmentally friendly and providing a positive user experience. They also reduce the harmful substances produced by the high-temperature decomposition of conventional atomizing media during combustion, thereby minimizing harm to the user.

[0003] Some existing aerosol-generating products incorporate a plug at the air inlet to prevent charring and scattered solids from being released during heating. However, this plug introduces new challenges. Specifically, the plug is made of a porous material, typically acetate fiber, which has a low melting point and melts at high temperatures. This deformation can block the airflow and even produce odor, negatively impacting user experience and potentially harming health. Utility Model Content

[0040] See also Figure 1 An embodiment of the present application provides an aerosol-generating product 100, which can be inserted into an aerosol-generating device. A heating element is provided in the aerosol-generating device, which can heat the aerosol-generating product 100 to generate aerosol for a user to take.

[0041] In the following embodiments, the aerosol-generating article 100 has a cylindrical structure, and the cross-section of the aerosol-generating article 100 is circular. It is understood that the shape of the aerosol-generating article 100 is not limited thereto. In other embodiments, the cross-section of the aerosol-generating article 100 may also be a regular or irregular shape, such as an ellipse or a rectangle.

[0042] like Figure 2 As shown, the aerosol-generating article 100 includes a body 20 and a packaging member 40. The packaging member 40 is formed of a wrapping material such as paper, tin foil, or aluminum foil. The packaging member 40 circumferentially wraps around the outer periphery of the body 20 to maintain the shape of the body 20. The body 20 includes a matrix section 21, a cooling section 22, an air passage section 23, and a filter section 24, which are arranged in sequence along the axial direction.

[0043] The matrix segment 21 has a solid cylindrical structure and can be formed from a plant-based solid matrix containing a specific aroma, such as a filament, sheet, granular, powdered, or cylindrical form, or from other types of ordered or disordered solid aerosol-generating matrices. Heating the matrix segment 21 generates an aerosol for the user to consume. It is understood that the material forming the matrix segment 21 is not limited. The matrix segment 21 can be formed from a single material or a mixture of multiple materials in varying proportions. Other substances can also be added to the matrix segment 21 to produce aerosols with different compositions and flavors to meet the varying needs of the user.

[0044] The cooling section 22 is located at one end of the matrix section 21. The cooling section 22 is a hollow cylindrical structure with both ends open. A first airflow channel 22a extending axially is formed within the cooling section 22. One end of the first airflow channel 22a is connected to the matrix section 21, and the other end is connected to the airway section 23. The cooling section 22 is used to guide the aerosol generated by the matrix section 21 and cool the aerosol flowing through the first airflow channel 22a to a temperature range suitable for user use. In some embodiments, the cooling section 22 can be formed from one or more heat exchange materials such as cellulose acetate, polylactic acid, resin, silica gel, or plant polysaccharides. It will be appreciated that the materials forming the cooling section 22 are not limited thereto and can be configured as needed to meet different cooling requirements.

[0045] The airway section 23 is located at one end of the cooling section 22 away from the matrix section 21. The airway section 23 is a hollow cylindrical structure with openings at both ends. A second airflow channel 23a extending axially is formed in the airway section 23. One end of the second airflow channel 23a is connected to the first airflow channel 22a, and the other end is connected to the filter section 24.

[0046] Please combine Figure 1 and Figure 2 As shown, further, the packaging 40 wrapped around the airway section 23 is provided with at least one auxiliary air inlet hole 40a, which connects the external environment with the second air flow channel 23a. The air from the external environment can enter the second air flow channel 23a through the auxiliary air inlet hole 40a, thereby effectively increasing the air intake volume and the total ventilation rate in the airway section 23. When the user inhales through the filter section 24, it is easier to bring out the effective substances produced by the matrix section 21, thereby having better suction consistency and effectively improving the user experience.

[0047] In a preferred embodiment, the packaging member 40 covering the air passage section 23 is provided with a plurality of auxiliary air inlet holes 40a. These auxiliary air inlet holes 40a are arranged circumferentially and spaced apart. Therefore, air from the external environment can evenly enter the second air flow channel 23a through the plurality of auxiliary air inlet holes 40a. It will be appreciated that the shape, number, and arrangement of the auxiliary air inlet holes 40a can be customized to meet different air intake requirements.

[0048] The filter section 24 is a solid cylindrical structure located at the end of the airway section 23 away from the cooling section 22. It is used to filter the aerosol, thereby improving its purity. In some embodiments, the material of the filter section 24 may include one or more of acetate fiber, polypropylene fiber, paper filter rod, regenerated aerosol generating matrix, polylactic acid fiber, resin, plant polysaccharide, silica gel, and ceramic. It is understood that the material of the filter section 24 is not limited to this and can be customized to meet different filtration requirements.

[0049] As described in the background, current aerosol-generating products feature an open-ended matrix segment. During heating, substances within the matrix segment inevitably leak into the aerosol-generating device. If not promptly cleaned, repeated heating can lead to contamination and shortened lifespan of the aerosol-generating device. Furthermore, the heated aerosol, which fills the aerosol-generating device, condenses and forms condensate and a large amount of viscous charred material, which is difficult to clean. This long-term effect seriously impairs the functionality of the aerosol-generating device and, in turn, the user experience.

[0050] Please continue reading Figure 2 To address the aforementioned issues, the body 20 of the aerosol-generating article 100 of the present application further includes a blocking member 25. This blocking member 25 is located at the end of the matrix segment 21 away from the cooling segment 22. The blocking member 25 blocks and absorbs solid matter and condensate generated during the heating process of the matrix segment 21. However, the blocking member 25 generally has a low melting point and melts in high-temperature environments. This melting can cause the blocking member 25 to deform and block the air path, resulting in increased aerosol concentration and even the production of unpleasant odors.

[0051] To address the above-mentioned problem, the main body 20 of the aerosol-generating product 100 of the present application further includes a first thermal insulation layer 26 , which covers at least a portion of the outer surface of the sealing member 25 and is located between the sealing member 25 and the packaging member 10 . The first thermal insulation layer 26 is used to prevent heat from being transferred to the sealing member 25 .

[0052] In this way, since at least part of the outer surface of the sealing member 25 is covered with the first thermal insulation layer 26 that can block heat transfer, the heat generated by the heating element and / or the heat of the heated matrix segment 21 can be effectively reduced from being transferred to the sealing member 25, thereby preventing the sealing member 25 from being overheated, melting and deforming, and producing odor.

[0053] It is understandable that, depending on the heating method and the required thermal insulation effect, the coverage area of ​​the first thermal insulation layer 26 can also be adjusted accordingly to achieve the optimal thermal insulation effect.

[0054] In some embodiments, the first thermal insulation layer 26 covers at least a portion of the sidewalls of the blocking member 25 and a portion of the end surface of the blocking member 25 facing the matrix segment 21. Thus, the first thermal insulation layer 26 covering the sidewalls of the blocking member 25 can be used to prevent heat from being transferred radially to the blocking member 25, and the first thermal insulation layer 26 covering the end surface of the blocking member 25 facing the matrix segment 21 can be used to prevent heat from being transferred axially to the blocking member 25.

[0055] In other embodiments, the first thermal insulation layer 26 only covers at least a portion of the side wall of the sealing member 25, while the end surface of the sealing member 25 facing the matrix segment 21 is not covered with the first thermal insulation layer 26. Therefore, the first thermal insulation layer 26 is mainly used to prevent heat from being transferred radially to the sealing member 25.

[0056] In some other embodiments, the first thermal insulation layer 26 only covers a portion of the end surface of the sealing member 25 facing the matrix segment 21, and the side wall of the sealing member 25 is not covered by the first thermal insulation layer 26. Therefore, the first thermal insulation layer 26 is mainly used to prevent heat from being transferred axially to the sealing member 25.

[0057] Specifically, in some embodiments, the aerosol generating device performs circumferential heating on the aerosol generating article 100 , and the heating element circumferentially surrounds the aerosol generating article 100 , so that the heat generated by the heating element is transferred radially toward the blocking member 25 .

[0058] like Figure 2 and Figure 3 As shown, in one embodiment, in the aerosol generating product 100 applied to the above-mentioned circumferentially heated aerosol generating device, the first thermal insulation layer 26 is a hollow cylindrical structure with both ends open, and the first thermal insulation layer 26 circumferentially surrounds the side wall of the sealing member 25 to completely cover all areas of the side wall of the sealing member 25.

[0059] In this way, the heat generated by the heating element can be blocked by the first heat insulating layer 26 , thereby preventing the heat generated by the heating element from being transferred radially toward the blocking member 25 , thereby effectively preventing the blocking member 25 from being overheated and melting.

[0060] like Figure 5 and Figure 6 As shown, in another embodiment, in the aerosol generating product 100 applied to the above-mentioned circumferentially heated aerosol generating device, a portion of the first thermal insulation layer 26 is in the form of a hollow cylindrical structure, circumferentially surrounding the side wall of the blocking member 25 to completely cover all areas of the side wall of the blocking member 25, and another portion of the first thermal insulation layer 26 is in the form of a circular ring, covering the edge of one end face of the blocking member 25 facing the matrix segment 21.

[0061] In this way, the heat generated by the heating element and the heat of the heated matrix segment 21 can be blocked by the first thermal insulation layer 26, thereby more effectively preventing the blocking member 25 from overheating and melting. Furthermore, because only the edge of the end surface of the blocking member 25 facing the matrix segment 21 is covered by the first thermal insulation layer 26, while it blocks heat transfer, it does not block external airflow from passing through the blocking member 25 into the matrix segment 21.

[0062] In some embodiments, the aerosol generating device performs central heating on the aerosol generating article 100 , and the heating element is inserted into the matrix segment 21 axially through the blocking member 25 , so that the heat generated by the heating element is transferred axially toward the blocking member 25 through the matrix segment 21 .

[0063] like Figure 8As shown, in the aerosol-generating article 100 used in the aforementioned centrally heated aerosol-generating device, a portion of the first thermal insulation layer 26 covers at least a portion of the sidewalls of the blocking member 25 and at least a portion of the sidewalls of the matrix segment 21, and a portion of the first thermal insulation layer 26 covers a portion of the end surface of the blocking member 25 facing the matrix segment 21. This effectively prevents heat from the matrix segment 21 from being transferred outward, thereby improving heating efficiency, and also effectively prevents heat from the heated matrix segment 21 from being transferred axially to the blocking member 25.

[0064] like Figure 8 and Figure 9 As shown, specifically in one embodiment, the longitudinal cross-section of the first thermal insulation layer 26 is "H"-shaped, a portion of the first thermal insulation layer 26 is cylindrical in structure, circumferentially surrounding the side wall of the blocking member 25 and the side wall of the matrix segment 21, thereby completely covering all areas of the side wall of the blocking member 25 and the side wall of the matrix segment 21, and another portion of the first thermal insulation layer 26 is annular in shape, so as to cover the edge of one end face of the blocking member 25 facing the matrix segment 21.

[0065] Please refer again Figure 2 In some embodiments, the aerosol generating article 100 further includes a second thermal insulation layer 27, which covers at least a portion of the outer surface of the cooling section 22, thereby effectively reducing heat transfer to the cooling section 22 and effectively lowering the temperature of the cooling section 22, thereby achieving a better cooling effect.

[0066] It can be understood that the coverage area of ​​the second thermal insulation layer 27 can be adjusted according to different heating methods and required thermal insulation effects.

[0067] In some embodiments, the second thermal insulation layer 27 covers at least a portion of the sidewalls of the cooling segment 22 and a portion of the end surface of the cooling segment 22 facing the matrix segment 21. Thus, the second thermal insulation layer 27 covering the sidewalls of the cooling segment 22 can be used to block heat from being transferred radially to the cooling segment 22, and the second thermal insulation layer 27 covering the end surface of the cooling segment 22 facing the matrix segment 21 can be used to block heat from being transferred axially to the cooling segment 22.

[0068] In other embodiments, the second thermal insulation layer 27 only covers at least a portion of the side wall of the cooling section 22, while the end surface of the cooling section 22 facing the matrix section 21 is not covered by the second thermal insulation layer 27. Therefore, the second thermal insulation layer 27 is mainly used to prevent heat from being transferred radially to the cooling section 22.

[0069] In some other embodiments, the second thermal insulation layer 27 only covers the end surface of the cooling section 22 facing the matrix section 21, but does not cover the side wall of the cooling section 22. Therefore, the second thermal insulation layer 27 is mainly used to prevent heat from being transferred axially to the cooling section 22.

[0070] like Figure 2and Figure 4 As shown, in one embodiment, in an aerosol generating product 100 used in an aerosol generating device with circumferential heating, the second thermal insulation layer 27 is a hollow cylindrical structure with both ends open, and the second thermal insulation layer 27 circumferentially surrounds the side wall of the cooling section 22 to completely cover the side wall of the cooling section 22.

[0071] In this way, the heat generated by the heating element can be blocked by the second heat insulation layer 27 , thereby preventing the heat generated by the heating element from being transferred radially toward the cooling section 22 , thereby effectively reducing the temperature of the cooling section 22 .

[0072] like Figure 5 、 Figure 7 as well as Figure 8 As shown, in another embodiment, in an aerosol generating product 100 of an aerosol generating device that is simultaneously applied to circumferential heating and central heating, a portion of the second thermal insulation layer 27 is in the shape of a hollow cylinder, circumferentially surrounding the side wall of the cooling section 22 to completely cover all areas of the side wall of the cooling section 22, and another portion of the second thermal insulation layer 27 is in the shape of a ring, covering all areas of an end face of the cooling section 22 facing the matrix section 21 (i.e., the second thermal insulation layer 27 circumferentially surrounds the first airflow channel 23a).

[0073] In this way, the heat generated by the heating element and the heat of the heated substrate segment 21 can be blocked by the second thermal insulation layer 27, and the airflow and aerosol can pass through the second thermal insulation layer 27 and smoothly enter the first airflow channel 22a.

[0074] Furthermore, the first and second insulation layers 26, 27 can be formed from food-grade insulation materials that are resistant to high temperatures, have low thermal conductivity (less than 0.04 W / (m·K)), and have low air permeability. In a preferred embodiment, the first and second insulation layers 26, 27 are formed from polyimide. It is understood that the materials forming the first and second insulation layers 26, 27 are not limited thereto and can be selected as needed. Furthermore, the materials forming the first and second insulation layers 26, 27 can be the same or different.

[0075] See also Figure 2 、 Figure 3 as well as Figure 4 In one embodiment of the present application, the aerosol-generating article 100 is used in a circumferentially heated aerosol-generating device. The first thermal insulation layer 26 is cylindrically shaped and surrounds the sidewall of the blocking member 25. The second thermal insulation layer 27 is cylindrically shaped and surrounds the sidewall of the blocking member 25. These layers effectively prevent heat generated by the heating element from being transferred axially to the blocking member 25 and the cooling section 22.

[0076] See also Figure 5 、 Figure 6 as well as Figure 7In one embodiment of the present application, the aerosol generating article 100 is applied to a circumferentially heated aerosol generating device. A portion of the first thermal insulation layer 26 is in a cylindrical structure to surround the side wall of the blocking member 25, and another portion of the first thermal insulation layer 26 is in an annular shape to surround the edge of one end face of the blocking member 25 facing the matrix segment 21. A portion of the second thermal insulation layer 27 is in a cylindrical shape to surround the side wall of the cooling segment 22, and another portion of the second thermal insulation layer 27 is in an annular shape to surround one end face of the cooling segment 22 facing the matrix segment 21. Therefore, on the one hand, it can effectively prevent the heat generated by the heating element from being transferred radially to the blocking member 25 and the cooling segment 22, and on the other hand, it can also prevent the heat of the heated matrix segment 21 from being transferred axially to the blocking member 25 and the cooling segment 22.

[0077] See also Figure 8 and Figure 9 In one embodiment of the present application, the aerosol generating article 100 is applied to a centrally heated aerosol generating device. A portion of the first thermal insulation layer 26 is cylindrically shaped to surround the side wall of the blocking member 25 and the side wall of the matrix segment 21, and another portion of the first thermal insulation layer 26 is annularly shaped to surround the edge of one end face of the blocking member 25 facing the matrix segment 21. A portion of the second thermal insulation layer 27 is cylindrically shaped to surround the side wall of the cooling segment 22, and another portion of the second thermal insulation layer 27 is annularly shaped to surround one end face of the cooling segment 22 facing the matrix segment 21. Therefore, on the one hand, energy loss can be reduced, and on the other hand, heat from the heated matrix segment 21 can be prevented from being transferred axially to the blocking member 25 and the cooling segment 22.

[0078] The aerosol generating article 100 described above can effectively reduce the heat transferred to the blocking member 25 by providing the first heat insulating layer 26, thereby slowing down or eliminating the problem of the blocking member 25 melting due to high temperature, and effectively preventing the generation of odor.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
