[0029] The present application discloses an aerosol generating product, which is used in a heat-not-burn device and can generate aerosol for a user to inhale when heated.

[0030] The aerosol generating product includes an outer tube body 1 and an inner cylinder 2. The outer tube body 1 has a sealed end 12 and an open end 13. The internal space of the outer tube body 1 is divided into a filtering section, a cooling section and a accommodating section 14 in sequence along the length direction of the outer tube body 1. The end of the accommodating section 14 away from the filtering section is the open end 13 of the outer tube body 1, and a filter element 15 is arranged in the filtering section; the outer diameter of at least part of the inner cylinder 2 in its length direction is less than or equal to the inner diameter of the outer tube body 1, so that this part of the structure of the inner cylinder 2 can be inserted into the accommodating section 14 from the open end 13, and an aerosol matrix 24 is arranged in the inner cylinder 2. In the aerosol-generating product with this structural arrangement, the aerosol matrix 24 in the accommodating section 14 can generate aerosol when heated, and the aerosol is inhaled by the user after passing through the cooling section and the filtering section along the length direction of the outer tube body 1, which can meet the basic functional requirements of the aerosol-generating product; and in terms of assembly, the aerosol-generating product with this structural arrangement facilitates the separate production and long-term storage of the inner cylinder 2 and the outer tube body 1 as semi-finished products. When the finished product is produced, only the inner cylinder 2 and the outer tube body 1 need to be assembled as the two semi-finished products, which can simplify the assembly process of the finished product, i.e., the aerosol-generating product, and facilitate the quality control of the finished product.

[0031] Specifically, in some embodiments, please refer to Figures 1 to 3, the outer tube body 1 includes an outer tube, which is preferably made of a low-cost paper material to form an outer paper tube 11. The outer paper tube 11 is formed by rolling paper into a ring and then gluing it together. The paper can be high-transmittance paper, metallic paper or metallized paper, wherein the metallized paper can be double-sided metallized paper or single-sided metallized paper.

[0032] The outer paper tube 11 is opened at both ends in its length direction. The internal space of the outer paper tube 11 is divided into a filtering section, a cooling section and a accommodating section 14 along the length direction of the outer paper tube 11. The outer tube body 1 also includes a filter element 15, which is arranged in the filtering section and is relatively fixed to the outer paper tube 11; the filter element 15 is preferably filter cotton, and the filter cotton is arranged in a columnar structure. The outer diameter of the filter element 15 is equal to the inner diameter of the outer paper tube 11, or it can be slightly larger than the inner diameter of the outer paper tube 11. The filter element 15 is installed in the outer paper tube 11 and has an interference fit with the outer paper tube 11 to achieve relative fixation with the outer paper tube 11; in other embodiments, the outer diameter of the filter element 15 can also be smaller than the outer diameter of the outer paper tube 11, and the filter element 15 is fixed in the outer paper tube 11 by gluing to achieve relative fixation with the outer paper tube 11.

[0033] Of course, in other embodiments, the filter element 15 may also include a cylindrical filter paper tube and a smaller-sized granular filter structure. The granular filter structure is located in the cylindrical filter paper tube, and the cylindrical filter paper tube is sealed at both ends in its length direction. For example, the sealing of the ends of the cylindrical filter paper tube can be achieved by encapsulating high-permeability paper or other sheet structures with air holes; the granular filter structure can be cellulose particles, which are encapsulated in the cylindrical filter paper tube to form the filter element 15.

[0034] In some embodiments, please continue to refer to Figures 1 to 3, the filter section is located at one end of the outer paper tube 11 in the length direction, and the filter element 15 blocks the end opening of the outer paper tube 11 away from the accommodating section 14, so that the outer tube body 1 forms a structure with one end open and the other end sealed.

[0035] Of course, in other embodiments, the filter element 15 can also be located at a position biased towards the middle of the length direction of the outer paper tube 11; the outer tube body 1 also includes a sealing member, which adopts a plate-like structure, a sheet-like structure or a membrane-like structure. The sealing member can be a highly transparent paper. The sealing member can also be made of other materials or paper with holes, other materials such as cellulose sheets, plastics, silicone or other heat-resistant materials that can withstand high temperatures without producing odor. Of course, the sealing member is preferably a sheet-like paper material; the sheet-like sealing member is bonded to the end opening of the outer paper tube 11 away from the accommodating section 14 by gluing to form a sealed end of the outer tube body 1.

[0036] In some embodiments, please continue to refer to Figures 1 to 3, the filter element 15 is located at one end of the outer paper tube 11 in the length direction, and the size of the filter section in the length direction of the outer paper tube 11 is smaller than the length of the entire outer tube body 1, so as to reserve a cooling section and an accommodating section 14 in the outer tube body 1, and the end of the accommodating section 14 away from the filter section is the open end of the outer tube body 1.

[0037] The cooling section is located between the filtration section and the accommodating section 14. The cavity of the cooling section houses a multifunctional component, which is a material that performs cooling, aroma enhancement, filtration, and harm reduction functions. This material can be in the form of granules, powders, beads, pastes, or random filaments. Its purpose is to reduce the aerosol temperature while also enhancing its aroma and reducing harmful components in the aerosol.

[0038] In some embodiments, referring to Figures 1 and 2 , the multifunctional component includes a fragrance member 16 , which is disposed within the cooling section and has pores through which aerosols can pass. The fragrance member 16 is inserted into the outer paper tube 11 through the open end 13 of the outer tube 1 , where it can contact the filter 15 . The fragrance member 16 can generate fragrance at high temperatures, which can then travel through the pores in the fragrance member 16 toward the filter 15 and be inhaled by the user, thereby enhancing the user experience. The placement of the fragrance member 16 within the outer tube 1 also provides a cooling effect. The high-temperature aerosol generated by heating the inner cylinder 2 can travel along the outer paper tube 11, pass through the fragrance member 16, and after cooling, enter the filter 15 , thereby reducing the temperature of the aerosol at the filter 15 and facilitating inhalation by the user.

[0039] In some embodiments, please continue to refer to Figures 1 and 2. The flavoring element 16 includes a flavoring medium. The flavoring medium can be in the form of particles, powder, popping beads, paste or disordered filaments. The flavoring medium can be attached with essence. The essence can produce fragrance at high temperature and enhance the fragrance of the aerosol. The flavoring medium can also reduce harmful components in the aerosol. The material of the flavoring medium is selected from but not limited to diatomaceous earth, fragrance particles, active peptides, thermal conductive gel, hydrated salt cooling material, waxy material, etc. Preferably, the flavoring medium can include cellulose particles with gaps between them. The cellulose particles are attached with essence, and the essence can volatilize into fragrance at high temperature. The flavoring medium can also include a disordered filamentous structure of cellulose, and the essence is attached to the disordered filamentous structure of cellulose.

[0040] Alternatively, in other embodiments, the fragrance member 16 includes a cylindrical fragrance paper tube and a fragrance medium located within the cylindrical fragrance paper tube. High-transparency paper or other sheet-like structures with air holes are bonded to both ends of the cylindrical fragrance paper tube to seal the fragrance medium within the cylindrical fragrance paper tube and prevent the fragrance medium from leaking out of the opening of the outer tube body 1 when the outer tube body 1 is placed horizontally or tilted. The outer diameter of the cylindrical fragrance paper tube is equal to the inner diameter of the outer paper tube 11, or can be slightly larger than the inner diameter of the outer paper tube 11. The fragrance member 16 is installed in the cooling section of the outer paper tube 11 and has an interference fit with the outer paper tube 11. For example, the cylindrical fragrance paper tube can be slightly deformed to achieve an interference fit with the outer paper tube 11 to achieve relative fixation with the outer paper tube 11. In other embodiments, the outer diameter of the cylindrical fragrance paper tube can be smaller than the outer diameter of the outer paper tube 11, and the entire fragrance member 16 can be fixed within the outer paper tube 11 by gluing to achieve relative fixation with the outer paper tube 11.

[0041] In some embodiments, a fixing member 17 is provided in the accommodating section, and the fixing member 17 is fixedly connected to the tube wall of the outer paper tube 11 to limit the position of the inner cylinder 2 within the outer paper tube 11. Specifically, referring to FIG1 , the fixing member 17 has an outer peripheral surface adapted to the inner wall of the outer tube 1; the outer diameter of the fixing member 17 is equal to or slightly larger than the inner diameter of the outer paper tube 11, and the fixing member 17 and the outer paper tube 11 have an interference fit to achieve a fixed connection between the fixing member 17 and the tube wall of the outer paper tube 11; of course, the outer diameter of the fixing member 17 can also be slightly smaller than the inner diameter of the outer paper tube 11. After the fixing member 17 is installed in the outer paper tube 11, the fixing member 17 is fixed to the inner wall of the outer paper tube 11 by gluing to achieve a fixed connection between the fixing member 17 and the outer paper tube 11.

[0042] In some embodiments, the fixing member 17 is a plate-like structure, a sheet-like structure, or a columnar structure, and is provided with perforations for the aerosol to pass through along the length direction of the outer tube 1. The fixing member 17 can be a sheet-like structure made of cellulose material or a columnar structure with a smaller axial dimension, or the fixing member 17 can also be made of other materials that do not deform at high temperatures and do not produce odor. The fixing member 17 is located on the side of the flavoring member 16 facing away from the filter member 15 in the length direction of the outer tube 1. In the embodiment where the flavoring member 16 includes a granular flavoring medium, the fixing member 17 can be used to seal the outer tube 1 to prevent the granular flavoring medium in the outer tube 1 from leaking out of the open end 13. Of course, the main function of the fixing member 17 is to fix the position of the inner cylinder 2 in the length direction of the outer tube 1, so as to assist the heating teeth or heating needles in the heat-not-burn device to penetrate into the inner cylinder 2 and achieve heating of the aerosol matrix 24 in the inner cylinder 2.

[0043] In some embodiments, the length of the receiving section 14 in the outer tube 1 is greater than or equal to the length of the inner cylinder 2; the length of the aerosol-generating article in the length of the outer tube 1 is equal to the length of the outer tube 1. Specifically, referring to Figures 1 to 3, the length of the receiving section 14 in the length of the outer tube 1 is greater than or equal to the length of the inner cylinder 2, so that the inner cylinder 2 can be completely inserted into the outer tube 1 from the open end 13 of the outer tube 1. Furthermore, the length of the aerosol-generating article in the length of the outer tube 1 is equal to the length of the outer tube 1, that is, after the inner cylinder 2 and the outer tube 1 are assembled, one of the axial end faces of the inner cylinder 2 in the length direction is flush with the end face of the open end 13 of the outer tube 1. This can prevent the entire aerosol-generating article from being too long in the length of the outer tube 1 and prevent the entire inner cylinder 2 from falling out of the outer tube 1.

[0044] Of course, in some other embodiments, the size of the accommodating section 14 in the length direction of the outer tube body 1 may also be smaller than the length size of the inner cylinder 2, so that the inner cylinder 2 can be partially inserted into the outer tube body 1 and fixedly connected to the outer tube body 1. After the inner cylinder 2 and the outer tube body 1 are assembled in place, at least part of the inner cylinder 2 in its length direction is exposed outside the outer tube body 1; or in other embodiments, the size of the accommodating section 14 in the length direction of the outer tube body 1 is much larger than the length size of the inner cylinder 2. After the inner cylinder 2 and the outer tube body 1 are assembled in place, the inner cylinder 2 is completely inserted into the outer tube body 1, and the axial end face of the inner cylinder 2 facing the outside of the outer tube body 1 is located in the outer tube body 1, and has a certain distance from the end face of the open end 13 of the outer tube body 1. This can also ensure that the inner cylinder 2 is entirely located in the outer tube body 1, preventing the inner cylinder 2 from falling out of the outer tube body 1.

[0045] In some embodiments, the outer diameter of the portion of the inner cylinder 2 intended to be inserted into the outer tube 1 is slightly larger than or equal to the inner diameter of the outer tube 1, and the inner cylinder 2 and the outer tube 1 have an interference fit to ensure that the inner cylinder 2 is securely installed in the outer tube 1. In other embodiments, the outer diameter of the portion of the inner cylinder 2 intended to be inserted into the outer tube 1 can be slightly smaller than the inner diameter of the outer tube 1, so that the inner cylinder 2 can be secured in the outer tube 1 by gluing, thereby achieving secure installation in the outer tube 1.

[0046] The inner cylinder 2 includes a cylindrical shell 21, which has a gas passage for the aerosol to pass through along the length of the inner cylinder 2. The aerosol matrix 24 is located within the cylindrical shell 21. Specifically, in some embodiments, referring to Figures 1 and 2, the cylindrical shell 21 includes a cylindrical paper tube 22. The cylindrical paper tube 22 can be formed by rolling and gluing paper. The paper can be highly transparent paper, metallic paper, or metallized paper. The cylindrical shell 21 also includes a sealing paper 23. The sealing paper 23 is provided with ventilation holes, or the sealing paper 23 is highly transparent paper. The material of the sealing paper 23 can be the same as or different from that of the cylindrical paper tube 22. The sealing paper 23 is connected to the openings at both ends of the cylindrical paper tube 22 by gluing to seal the aerosol matrix 24 within the cylindrical shell 21 and prevent the aerosol matrix 24 from leaking out of the cylindrical shell 21.

[0047] Furthermore, the aerosol matrix 24 is in a granular and / or random filamentary form. Referring to Figures 1 and 2 , the aerosol matrix 24 can be a granular and / or random filamentary structure made from tobacco products. The aerosol matrix 24 is encapsulated within the cylindrical housing 21, with gaps between the granular and random filamentary structures to allow the generated aerosol to pass through.

[0048] In other embodiments, the inner cylinder 2 can also be a capsule structure, which is a capsule-style structure commonly found in pharmaceuticals. The inner cylinder 2 includes a cylindrical shell 21 and an aerosol matrix. The cylindrical shell 21 has a cavity for accommodating the aerosol matrix. The cylindrical shell 21 includes a first shell and a second shell arranged along its axial direction. The first shell is a cylindrical shell-like structure with one end sealed and the other end open. The material of the first shell is cellulose, plastic, silicone, or other heat-resistant materials that can withstand high temperatures without producing odor. Exemplarily, the first shell includes a cylindrical shell with two ends open. The cylindrical shell can be formed by winding and gluing paper. The paper can be high-transmittance paper, metallic paper, or metallized paper. The first shell also includes a sealing member, which can be sealing paper. The sealing paper is fixed to one end of the cylindrical shell by gluing to form the sealed end of the first shell. The sealing paper is provided with air holes or is high-transmittance paper to allow the aerosol to pass through. Alternatively, the cylindrical shell and the sealing member in other embodiments may also be made of high-temperature resistant plastic or silica gel, and the sealing member may be provided with a through-hole structure for the aerosol to pass through.

[0049] The second shell also has a structure with one end sealed and the other end open. The structure of the second shell may be the same as that of the first shell, or there may be certain differences. The open ends of the first shell and the second shell are inserted into each other and interference fit to form a cylindrical shell 21. The first shell and the second shell form a receiving cavity for accommodating the aerosol matrix. Alternatively, the first shell and the second shell are inserted into each other and fixed by gluing to form a cylindrical shell 21.

[0050] In some other embodiments, please refer to Figure 3, the inner cylinder 2 includes an aerosol matrix 24, and the tobacco product containing the aerosol matrix 24 is a single-layer or multi-layer sheet structure matrix. The single-layer or multi-layer sheet structure matrix containing the aerosol matrix 24 is rolled and bonded into a cylinder, and then cut into small sections according to the length size requirements of the inner cylinder 2 to form the entire inner cylinder 2.

[0051] In the present application, the outer tube body 1 and the inner cylinder 2 can be prefabricated to form a semi-finished product of an aerosol generating product. Please refer to Figures 1 to 3. The outer tube body 1 can be the third semi-finished product 33 as shown in Figure 1, or the fourth semi-finished product 34 as shown in Figure 1, or the fifth semi-finished product 35 as shown in Figure 2.

[0052] Continuing with Figures 1 to 3 , in some embodiments, when assembling the outer tube body 1 as a semi-finished aerosol-generating product, a filter 15 is inserted into the outer paper tube 11, sealing one end of the outer paper tube 11 to form the sealed end of the outer tube body 1 , thereby forming a fifth semi-finished product 35 . Based on the fifth semi-finished product 35 , if the aerosol-generating product has a flavoring function, a flavoring element 16 may be inserted into the outer paper tube 11 to form a fourth semi-finished product 34 . If the flavoring medium is granular, the fourth semi-finished product 34 must be stored to prevent the flavoring medium from escaping from the outer paper tube 11 . Based on the fourth semi-finished product 34 , if the aerosol-generating product is suitable for embedded heating teeth or heating needles, a fixing element 17 may be inserted into the outer paper tube 11 to securely connect the fixing element 17 to the outer paper tube 11 , thereby forming a third semi-finished product 33 . The fifth semi-finished product 35 , the fourth semi-finished product 34 , and the third semi-finished product 33 can all be stored and sold separately.

[0053] Continuing to refer to Figures 1 to 3, the inner cylinder 2, as a semi-finished product of the aerosol-generating article, can be the second semi-finished product 32 as shown in Figures 1 and 2, or can also be the first semi-finished product 31 as shown in Figure 3. In some embodiments, during the assembly process of the inner cylinder 2, a cylindrical paper tube 22 is first made, one end of the cylindrical paper tube 22 is sealed with a sealing member, and the aerosol matrix 24 is filled into the cylindrical paper tube 22 through the other end opening of the cylindrical paper tube 22. Finally, the cylindrical paper tube 22 is sealed again with a sealing member to seal the other end opening of the cylindrical paper tube 22, thereby forming the entire inner cylinder 2, that is, also forming the entire second semi-finished product 32. In other embodiments, during the assembly process of the inner cylinder 2, the sheet-like aerosol matrix 24 is rolled and bonded into a cylinder to form the entire first semi-finished product 31.

[0054] The above-mentioned semi-finished products can be prefabricated and stored before the assembly of the aerosol generating product, so that when there is a demand for the aerosol generating product, the two parts of the semi-finished products can be directly assembled. This can simplify the assembly process of the finished product, i.e., the aerosol generating product, and facilitate quality control during the assembly process of the aerosol generating product.

[0055] In addition, the semi-finished products formed by the outer tube body 1 in this application, such as the third semi-finished product 33 and the fifth semi-finished product 35, and the semi-finished products of the inner cylinder 2, such as the second semi-finished product 32 and the first semi-finished product 31, can be sold separately as products to expand the types of products sold.

[0056] The present application also discloses a heat-not-burn device that can generate an aerosol for inhalation by a user when heated. The heat-not-burn device includes the aerosol-generating article of any of the above embodiments.

[0057] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
