Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0025] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connected" and "coupled" in this application include both direct and indirect connections unless otherwise specified.

[0026] An embodiment of the present application provides an aerosol-generating product, which is used to be connected to a heating device 80 so as to be heated by the heating device 80 to generate an aerosol.

[0027] Reference Figures 1 to 5 As shown, the aerosol generating article includes a filter section 10, a sealing section 50 and a smoke-generating section 40, the filter section 10 is located at the downstream end of the aerosol generating article, the sealing section 50 is located at the upstream end of the aerosol generating article, and the smoke-generating section 40 is located between the filter section 10 and the sealing section 50; the smoke-generating section 40 includes a first aerosol generating matrix 41, and the first aerosol generating matrix 41 is used to generate aerosol; the sealing section 50 includes a first breathable wrapping portion 51 and a first flavoring matrix 52 combined with the first breathable wrapping portion 51, the first flavoring matrix 52 is used to receive heat conducted by the first aerosol generating matrix 41 to generate a first flavoring substance, and the first flavoring substance is suitable for increasing the concentration and / or aroma of the aerosol.

[0028] In the embodiment of the present application, the downstream end of the aerosol generating article and the upstream end of the aerosol generating article are relative to the flow direction of the aerosol, and the downstream end of the aerosol generating article is closer to the user.

[0029] The filter segment 10 is used for filtering and is made of filter material, and the filter material can be selected according to the use requirements. For example, the filter segment 10 is made of cellulose acetate tow, or one or more products of breathable materials such as polylactic acid fiber, polyethylene, etc.

[0030] The sealing section 50 is used to seal the upstream end of the aerosol-generating article to prevent the substance in the smoking section 40 (such substance being the first aerosol-generating substrate 41 ) from falling out of the aerosol-generating article.

[0031] The first air-permeable wrapping portion 51 in the sealing section 50 is made of a breathable material. Air can enter the smoking section 40 through the first air-permeable wrapping portion 51, allowing the aerosol generated by the first aerosol-generating substrate 41 in the smoking section 40 to be released from the filter section of the aerosol-generating article along with the air drawn into the aerosol-generating article. The first air-permeable wrapping portion 51 also prevents the first flavoring substrate 52 from falling out of the aerosol-generating article.

[0032] In the embodiment of the present application, the first aerosol generating matrix 41 in the smoking section 40 is used to generate aerosol, and the first flavoring matrix 52 in the sealing section 50 is heated by the heat conducted by the first aerosol generating matrix 41 and produces a first flavoring substance. The first flavoring substance produced by the first flavoring matrix 52 is suitable for increasing the concentration and / or aroma of the aerosol generated by the first aerosol generating matrix 41, thereby effectively improving the sensory quality of the aerosol generating product.

[0033] In one embodiment, the first breathable wrapping portion 51 and the first flavoring matrix 52 are stacked. The stacking of the first breathable wrapping portion 51 and the first flavoring matrix 52 may have a variety of specific structures. For example, along the length direction of the aerosol generating article (i.e., the direction from the upstream end to the downstream end), or along the radial direction of the aerosol generating article, the first breathable wrapping portion 51 and the first flavoring matrix 52 are alternately stacked in sequence. For another example, the first breathable wrapping portion 51 and the first flavoring matrix 52 are stacked and then rolled or folded. For example, along the length direction of the aerosol generating article, or along the length direction of the aerosol generating article, the first breathable wrapping portion 51 and the first flavoring matrix 52 are staggered, at least two layers of the first breathable wrapping portion 51 are connected, and at least two layers of the first flavoring matrix 52 are connected, etc., and are formed by pressing.

[0034] In one embodiment, the first breathable wrapping portion 51 wraps around the first flavoring matrix 52. The first breathable wrapping portion 51 can have a variety of specific structures for wrapping the first flavoring matrix 52. For example, the first breathable wrapping portion 51 may be embedded with multiple first flavoring matrices 52. For example, the first breathable wrapping portion 51 may be wrapped around the periphery of the first flavoring matrix 52. In another example, the first breathable wrapping portion 51 may be formed with a placement cavity, and the first flavoring matrix 52 may be mounted within the placement cavity.

[0035] In one embodiment, the first breathable wrapping portion 51 is at least partially located at the end of the sealing section 50 facing away from the filter section 10. In this case, the first breathable wrapping portion 51 can effectively prevent substances in the smoke-generating section 40 (e.g., the first aerosol-generating matrix 41) and substances in the sealing section 50 (e.g., the first flavor-enhancing matrix 52) from falling out of the aerosol-generating article. In particular, the portion of the first breathable wrapping portion 51 located at the end of the sealing section 50 facing away from the filter section 10 can effectively prevent substances in the smoke-generating section 40 and the sealing section 50 from falling out of the aerosol-generating article. Furthermore, when the heating needle 82 or heating sheet is removed from the aerosol-generating article, the first breathable wrapping portion 51 cleans the heating needle 82 or heating sheet, thereby achieving a self-cleaning effect. This effectively prevents substances in the aerosol-generating article from adhering to the heating needle 82 or heating sheet after repeated use, which could cause a burnt odor in the aerosol-generating article and affect its sensory quality. Moreover, since the first breathable wrapping portion 51 is made of breathable material, the material density of the first breathable wrapping portion 51 is relatively small, which also facilitates the insertion or removal of the heating needle 82 or the heating sheet into or out of the aerosol generating product.

[0036] In one embodiment, the first flavor enhancing matrix 52 includes a tobacco or non-tobacco solid matrix. In this case, the first flavor enhancing matrix 52 can generate an aerosol or a substance that can enhance the aroma of the aerosol generated by the first aerosol generating matrix 41, thereby effectively improving the sensory quality of the aerosol generating product.

[0037] In one embodiment, the first flavoring substrate 52 includes a second aerosol-generating substrate, and the first flavoring substance is a corresponding aerosol. For example, when the first flavoring substrate 52 contains a tobacco component, the first flavoring substance is a nicotine-containing aerosol; when the first flavoring substrate 52 contains a non-tobacco component, the first flavoring substance is a nicotine-free aerosol. The second aerosol-generating substrate is also used to generate an aerosol. The aerosol generated by the second aerosol-generating substrate mixes with the aerosol generated by the first aerosol-generating substrate 41 to increase the concentration of the aerosol, thereby improving the sensory quality of the aerosol-generating product.

[0038] In another embodiment, the first flavoring substrate 52 includes a first flavor-generating substrate, such as a volatilized or decomposed fragrance, and the first flavoring substance is a flavored aerosol. Specifically, the first flavor-generating substrate is used to generate a flavored aerosol. This flavored aerosol mixes with the aerosol generated by the first aerosol-generating substrate 41 to enhance the flavor of the aerosol generated by the first aerosol-generating substrate 41, thereby improving the sensory quality of the aerosol-generating product.

[0039] It is understood that the second aerosol-generating substrate and the first flavor-generating substrate can be mixed and disposed within the sealing section 50 , while increasing the concentration and flavor of the aerosol generated by the first aerosol-generating substrate 41 to enhance the sensory quality of the aerosol-generating product.

[0040] In one embodiment, each first flavoring matrix 52 is in at least one of the following forms: filaments, flakes, granules, or threads, depending on the specific application requirements. That is, the first flavoring matrix 52 can be in one form or a mixture of multiple forms.

[0041] Specifically, for example, the second aerosol-generating substrate is in at least one of a filament, a flake, a granular, and a thread-like shape. For another example, the first flavor-generating substrate is in at least one of a filament, a flake, a granular, and a thread-like shape.

[0042] In one embodiment, the first aerosol generating substrate 41 may also be in at least one of a filamentous, flake-like, granular, and linear shape, which may be configured according to specific usage requirements.

[0043] In one embodiment, the aerosol generating article further includes an isolation segment 60 located between the filter segment 10 and the smoke-generating segment 40 and connected to the smoke-generating segment 40. The isolation segment 60 includes a second breathable wrapping portion 61 and a second flavoring matrix 62 combined with the second breathable wrapping portion 61. The second flavoring matrix 62 is used to receive heat conducted by the first aerosol generating matrix 41 to generate a second flavoring substance. The second flavoring substance is suitable for increasing the concentration and / or aroma of the aerosol.

[0044] In the embodiment of the present application, the second breathable wrapping portion 61 in the isolation section 60 is made of a breathable material. The aerosol generated by the first aerosol-generating substrate 41 in the smoking section 40 passes through the isolation section 60 along with the air drawn into the aerosol-generating article, carrying the second flavoring substance along with it, and is ultimately released from the filter section 10. The second breathable wrapping portion 61 also prevents the second flavoring substance 62 from migrating and potentially affecting the quality of the aerosol-generating article. The material and construction of the second breathable wrapping portion 61 can be the same as those of the first breathable wrapping portion 51.

[0045] Because isolation segment 60 includes a second flavoring matrix 62, heat transferred from first aerosol-generating matrix 41 heats second flavoring matrix 62 and produces a second flavoring substance. This second flavoring substance is suitable for increasing the concentration and / or aroma of the aerosol generated by first aerosol-generating matrix 41, thereby effectively improving the sensory quality of the aerosol-generating product. The form and composition of second flavoring matrix 62 can be similar to first flavoring matrix 52. For example, second flavoring matrix 62 can be in the form of filaments, flakes, granules, or threads, and can be composed of a tobacco or non-tobacco solid matrix.

[0046] In one embodiment, the first breathable wrapping portion 51 is a fluffy fibrous member; the aerosol-generating article further includes a tubular body 70 that wraps the filter section, the sealing section, and the smoke-generating section. The fluffy fibrous member is compressively sealed within the tubular body 70. In the above-described structure of this embodiment of the present application, the fluffy fibrous member can elastically plug the upstream end of the tubular body 70, making sealing the upstream end simpler and more convenient. Furthermore, there is no need to use adhesives for sealing, which can also save adhesive costs and process steps.

[0047] In one embodiment, the second breathable wrapping portion 61 is a fluffy fiber member that is compressibly sealed within the tube body 70. The second breathable wrapping portion 61 eliminates the need for adhesives, offering advantages such as simple and convenient assembly, and saving adhesive costs and process steps. Compared to sealing methods using sealing paper, aerosol-generating products sealed with fluffy fiber members offer more flexible assembly methods. The fiber member can be elastically inserted into one end of the tube body 70, followed by the material for the smoke-generating segment 40, the support segment 30, the filter segment 10, and so on. Alternatively, the filter segment 10 can be installed into one end of the tube body 70 first, followed by the support segment 30 from the other end, followed by the material for the smoke-generating segment 40, and finally, the fiber member can be inserted to seal the tube body.

[0048] In one embodiment, the first breathable wrapping portion 51 includes at least one of cotton fiber pieces, polypropylene material pieces, polyamide material pieces, polyethylene terephthalate material pieces, non-woven fabrics, one-piece cotton, acetate fiber material pieces, propionate fiber material pieces, and cellulose material pieces.

[0049] Polypropylene components are made from polypropylene (PP). Polyamide components are made from polyamide (PA). Polyethylene terephthalate components are made from polyethylene terephthalate (PET). Non-woven fabrics are made from polyester and polyester fibers. The integrated cotton is a microfiber material with a high porosity.

[0050] In the embodiment of the present application, when the first breathable wrapping portion 51 comprises at least one of a cotton fiber member, a polypropylene material member, a polyamide material member, a polyethylene terephthalate material member, a non-woven fabric, a one-piece cotton member, an acetate fiber material member, a propionate fiber material member, and a cellulose material member, the first breathable wrapping portion 51 is a breathable material member, and air can enter the smoking section 40 through the first breathable wrapping portion 51. For example, when the first breathable wrapping portion 51 comprises multiple material members, the multiple material members can be stacked in an orderly manner or randomly contacted together to form a predetermined shape.

[0051] In one embodiment, the second breathable wrapping portion 61 also includes at least one of cotton fiber parts, polypropylene material parts, polyamide material parts, polyethylene terephthalate material parts, non-woven fabrics, one-piece cotton, acetate fiber material parts, propionate fiber material parts, and cellulose material parts. Please refer to the above description for details.

[0052] In one embodiment, referring to Figure 2 As shown, the aerosol-generating product further includes a hollow tube body 70, a cooling section 20, and a support section 30. Along the length of the aerosol-generating product, the filter section 10, the cooling section 20, the support section 30, the smoke-generating section 40, and the sealing section 50 are sequentially arranged within the tube body 70. The tube body 70 has sufficient hardness and wraps and supports the filter section 10, the cooling section 20, the support section 30, the smoke-generating section 40, and the sealing section 50 to prevent them from deforming. The present embodiment of the application does not specifically limit the material of the tube body 70. For example, the tube body 70 may be a paper tube made of cigarette paper, or an aluminum foil tube. The support section 30 provides support and position limiting functions. For example, when the heating needle 82 or heating sheet is inserted into the aerosol-generating product, it prevents the smoke-generating section 40 from moving toward the filter section 10.

[0053] In one embodiment, referring to Figure 3 As shown, the aerosol-generating article further comprises a hollow tube body 70, a cooling section 20, and a support section 30. The tube body 70 is a thick paper tube with a wall thickness of no less than 0.15 mm to maintain sufficient strength. Along the length of the aerosol-generating article, the tube body 70 is sequentially provided with a filter section 10, a cooling section 20, a support section 30, an isolation section 60, a smoke-generating section 40, and a sealing section 50.

[0054] In the aerosol-generating product in the embodiment of the present application, the first aerosol-generating matrix 41 in the smoking section 40 is used to generate an aerosol, and the first flavoring matrix 52 in the sealing section 50 receives heat conducted by the first aerosol-generating matrix 41 to generate a first flavoring substance. The first flavoring substance is suitable for increasing the concentration and / or aroma of the aerosol generated by the first aerosol-generating matrix 41, thereby effectively improving the sensory quality of the aerosol-generating product. In addition, the sealing section 50 can effectively prevent the substance in the smoking section 40 (such as the first aerosol-generating matrix 41) from falling out of the aerosol-generating product. When the heating needle 82 or the heating sheet is pulled out of the aerosol-generating product, the sealing section 50 cleans the heating needle 82 or the heating sheet to achieve the purpose of self-cleaning, further improving the sensory quality of the aerosol-generating product.

[0055] The present application also provides an aerosol generating system, referring to Figure 2-Figure 5As shown, the aerosol generating system includes a heating device 80 and an aerosol generating product as described above; the heating device 80 is provided with a heating element; the heating element only heats the smoking section 40, so that the first aerosol generating matrix 41 in the smoking section 40 is heated to generate aerosol; the heat conducted from the first aerosol generating matrix 41 to the sealing section 50 can heat the first flavoring matrix 52 in the sealing section 50 to generate a first flavoring substance, which is suitable for increasing the concentration and / or aroma of the aerosol.

[0056] Specifically, refer to Figure 4 and Figure 5 As shown, the heating device 80 is provided with a receiving chamber 81 , and a portion of the aerosol generating article is assembled in the receiving chamber 81 , wherein at least a portion of the filter segment 10 in the aerosol generating article is exposed in the receiving chamber 81 .

[0057] During the heating process of the smoking segment 40 in the aerosol-generating article, a temperature difference exists between the smoking segment 40, the heating element, and the sealing segment 50, causing the sealing segment 50 to be heated. When the sealing segment 50 is heated indirectly by the energy of the heating element (primarily by heat conducted by the first aerosol-generating substrate 41), the first flavoring substrate 52 within the sealing segment 50 produces a first flavoring substance, thereby increasing the concentration and / or aroma of the aerosol.

[0058] In the aerosol generating system of the embodiment of the present application, the heating element only heats the smoking section 40, causing the first aerosol generating matrix 41 in the smoking section 40 to generate aerosol; the heat generated by the heating of the smoking section 40 causes the first flavoring matrix 52 in the sealing section 50 to be heated to generate a first flavoring substance, and the first flavoring substance increases the concentration and / or aroma of the aerosol, thereby effectively improving the sensory quality of the aerosol generating product.

[0059] In one embodiment, the heating device is provided with a accommodating cavity 81; the heating element is at least partially located in the accommodating cavity 81, and the portion of the heating element located in the accommodating cavity 81 is inserted into the sealing section 50 and the smoking section 40 in sequence, and only the portion of the heating element located in the smoking section 40 is used for heating.

[0060] In the above structure of the embodiment of the present application, the heating element is a heating needle 82 or a heating plate.

[0061] In the embodiment of the present application, only the portion of the heating needle 82 or the heating sheet (i.e., the heating element) located within the smoking section 40 is used for heating, and the portion of the heating needle 82 or the heating sheet located within the sealing section 50 is not used for heating. That is, the heating needle 82 or the heating sheet only heats the smoking section 40 but not the sealing section 50. When the heating needle 82 or the heating sheet extends out of the smoking section 40 away from the sealing section 50, the portion of the heating needle 82 or the heating sheet extending out of the smoking section 40 is also not used for heating.

[0062] There are many ways to achieve the above structure, which are not specifically limited in the embodiments of the present application. For example, the non-heating portion of the heating needle 82 or the heating sheet can be wrapped with an insulating layer 84 of insulating material, such as polyetheretherketone (PEEK), vacuum insulation tubes, aerogel insulation materials, etc. For another example, the portion of the heating needle 82 or the heating sheet that contacts the sealing section 50 is treated to reduce resistance, such as by coating it with a precious metal (such as silver). After the resistance of the heating needle 82 or the heating sheet is reduced, the heat generated is very small or basically no heat is generated.

[0063] When the aerosol generating system in the embodiment of the present application is used, taking the heating needle 82 as an example, the process is as follows:

[0064] The aerosol generating article is pushed into the accommodating chamber 81, and the heating needle 82 first contacts the surface of the sealing section 50 facing away from the smoking section 40. By applying force to the aerosol generating article, the heating needle 82 sequentially penetrates the sealing section 50 and the smoking section 40 until the surface of the sealing section 50 facing away from the smoking section 40 contacts the bottom of the accommodating chamber 81, thereby preventing the aerosol generating article from being pushed further in. At this point, the heated portion of the heating needle 82 contacts the smoking section 40. Figure 4 FIG. 8 is a schematic diagram of the heating needle 82 inserted into the aerosol generating article.

[0065] The heating needles 82 heat the smoke-generating segment 40, causing the first aerosol-generating substrate 41 in the smoke-generating segment 40 to generate aerosol. Simultaneously, the sealing segment 50 is indirectly heated by the energy of the heating needles 82 (primarily by heat conducted from the first aerosol-generating substrate 41), causing the first flavoring substrate 52 in the sealing segment 50 to produce a first flavoring substance. This first flavoring substance, along with the aerosol generated by the first aerosol-generating substrate 41, flows out of the filter segment 10.

[0066] After use, the aerosol-generating article is removed from the accommodating chamber 81. The sealing section 50 effectively prevents the substance within the smoke-generating section 40 (e.g., the first aerosol-generating substrate 41) from falling out of the aerosol-generating article. The sealing section 50 also cleans the heating needle 82 when it is removed from the aerosol-generating article, effectively preventing the substance within the aerosol-generating article from adhering to the heating needle 82 after repeated use, which could cause a burnt odor in the aerosol-generating article and affect its sensory quality.

[0067] Therefore, each time the aerosol generating system is used, the sealing section 50 can automatically clean the heating needle 82 by wiping.

[0068] In another embodiment, the heating element is arranged around the circumference of the accommodating cavity and surrounds the periphery of the smoking segment, so as to heat only the smoking segment.

[0069] Further, refer to Figure 5As shown, the heating element is a circumferential heating element 83, which is arranged around the axis of the accommodating cavity 81. The circumferential heating element 83 at least corresponds to the smoking section 40, and the portion of the circumferential heating element 83 corresponding to the smoking section 40 is used for heating.

[0070] When the aerosol generating system in the embodiment of the present application is used, the process is as follows:

[0071] The aerosol generating product is pushed into the accommodating chamber 81 until the surface of the sealing section 50 facing away from the smoking section 40 contacts the bottom of the accommodating chamber 81, thereby preventing the aerosol generating product from being pushed in further. Figure 5 shown.

[0072] The peripheral heating element 83 heats the smoking segment 40, causing the first aerosol-generating substrate 41 in the smoking segment 40 to generate aerosol. Simultaneously, the sealing segment 50 is indirectly heated by the energy of the peripheral heating element 83 (primarily by heat conducted from the first aerosol-generating substrate 41). The first flavoring substrate 52 in the sealing segment 50 produces a first flavoring substance, which, along with the aerosol generated by the first aerosol-generating substrate 41, flows out of the filtering segment 10.

[0073] When the aerosol-generating product further includes an isolation segment 60, the isolation segment 60 is indirectly heated using the energy of the peripheral heating element 83 (mainly the heat conducted by the first aerosol-generating matrix 41), and the second flavoring matrix 62 in the isolation segment 60 produces a second flavoring substance. The second flavoring substance flows out of the filter segment 10 together with the aerosol generated by the first aerosol-generating matrix 41, thereby further increasing the concentration and / or aroma of the aerosol generated by the first aerosol-generating matrix 41, thereby further improving the sensory quality of the aerosol-generating product.

[0074] To adapt the heating method of the heating needles 82 and the peripheral heating element 83 of the aerosol generating system, the diameter of the aerosol-generating article can be adjusted accordingly. For example, the diameter of the aerosol-generating article adapted for the heating needles 82 can be slightly larger, such as 6.50mm-7.50mm. Alternatively, the diameter of the aerosol-generating article adapted for the peripheral heating element 83 can be slightly smaller, such as 4.0mm-6.0mm, to facilitate rapid smoke generation and improve thermal efficiency.
