[0002] With increasing consumer health awareness, the tobacco industry is constantly responding to evolving consumer demands and accelerating the research and development and promotion of new tobacco products. Among these, heated non-combustible aerosol generation technology is widely regarded as a hope and direction for the sustainable development of the tobacco industry. In heated non-combustible aerosol generation technology, aerosol-generating products are placed in an aerosol-generating device, causing the aerosol-generating products to form aerosols.

[0003] However, in related technologies, when aerosol-generated products are inhaled by users, the aerosol inlet temperature is too high and the suction resistance is too great, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this application is to provide a quaternary aerosol generating product and an aerosol generating system, which at least solves the problems of excessively high aerosol inlet temperature and excessive suction resistance.

[0005] In a first aspect, embodiments of this application provide a quaternary aerosol generating article, the quaternary aerosol generating article comprising: a filter section, a first functional section, a second functional section, and a smoke generating section; the filter section, the first functional section, the second functional section, and the smoke generating section are arranged sequentially along the axial direction of the quaternary aerosol generating article, the second functional section is located at one end of the smoke generating section facing or away from the first functional section, and at least one section downstream of the smoke generating section is formed by the aggregation of pleated fiber sheets to form an aerosol channel.

[0006] In one embodiment, the second functional segment is a sealing segment; the sealing segment is connected to the end of the smoke-generating segment opposite to the first functional segment, and the sealing segment is formed by gathering together pleated fiber sheets.

[0007] In one embodiment, at least one of the filter segment, the first functional segment, and the second functional segment is provided with a fragrance-carrying substance, which is used to generate a fragrance-generating substance to mix with the aerosol generated by the smoke-generating segment.

[0008] In one embodiment, the fragrance-carrying substance includes at least one of fragrance-carrying beads, fragrance-carrying core wire, fragrance-carrying particles, and fragrance-carrying gel beads.

[0009] In one embodiment, at least one of the first functional segment and the second functional segment is provided with an air passage, the air passage connecting the smoke-generating segment and the filter segment, and the air passage is provided with a fragrance-carrying capsule.

[0010] In one embodiment, one of the first functional segment and the second functional segment, other than being formed by winding fiber sheets, includes a frame structure; the frame structure includes a first frame, a second frame, and a plurality of connecting strips, the first frame and the second frame being spaced apart along the axial direction of the quaternary aerosol-generated product, the plurality of connecting strips being located between the first frame and the second frame, and each connecting strip connecting the first frame and the second frame respectively, the plurality of connecting strips being spaced apart along the circumferential direction of the quaternary aerosol-generated product.

[0011] In one embodiment, a cooling hole is provided in at least one corresponding section of the outer casing between the filter section and the smoke-generating section, and the cooling hole is connected to the first functional section.

[0012] In one embodiment, at least one section between the filter section and the smoke-generating section is a cavity enclosed by the outer shell, and the cooling hole is opened at the corresponding part of the outer shell in the cavity.

[0013] In one embodiment, the smoke-generating section is provided with smoke-generating particles, and the end of the smoke-generating section facing away from the second functional section is covered with a shielding layer. The shielding layer is provided with a plurality of mesh holes, and the aperture of the mesh holes is smaller than the diameter of the smoke-generating particles.

[0014] In a second aspect, embodiments of this application provide an aerosol generation system, characterized in that the aerosol generation system includes an aerosol generation device and the quaternary aerosol generation product described in any one of the first aspects above;

[0015] The smoke-generating section is located in the aerosol generating device, which is used to heat the smoke-generating section.

[0016] In this embodiment, since at least one section downstream of the smoke-generating section is formed by the aggregation of wrinkled fiber sheets, there are gaps between adjacent layers of wrinkled fiber sheets along the radial direction of the quaternary aerosol generating product. These gaps effectively cool the aerosol generated by the quaternary aerosol generating product, preventing high aerosol inlet temperatures during user inhalation. Furthermore, these gaps act as channels for aerosol flow, preventing excessive suction resistance in the quaternary aerosol generating product. In other words, in this embodiment, by providing a filter section, users can inhale the quaternary aerosol generating product through the filter section. The fact that at least one section downstream of the smoke-generating section is formed by the aggregation of wrinkled fiber sheets creates gaps between the wrinkled fiber sheets, cooling the aerosol and preventing high aerosol inlet temperatures and excessive suction resistance in the aerosol generating product. In this embodiment of the application, the aerosol inlet temperature can be effectively reduced, and the absorption resistance of the quaternary aerosol product can be reduced.

Detailed Implementation

[0030] The terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise stated, "multiple" means two or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] like Figures 1 to 10 As shown, the quaternary aerosol generating product includes: a shell and a filter section 10, a first functional section 20, a second functional section, and a smoke generating section 40 enclosed within the shell.

[0034] The filter section 10, the first functional section 20, and the smoke-generating section 40 are arranged sequentially along the axial direction of the quaternary aerosol generating article. The second functional section is located at one end of the smoke-generating section 40 facing or away from the first functional section 20. At least one section downstream of the smoke-generating section 40 is formed by the aggregation of pleated fiber sheets to form an aerosol channel.

[0035] In this embodiment, since at least one section downstream of the smoke-generating section 40 is formed by the aggregation of pleated fiber sheets, after the pleated fiber sheets 001 are aggregated, there is a gap between adjacent layers of pleated fiber sheets 001 along the radial direction of the quaternary aerosol generating product. This gap allows the aerosol generated by the quaternary aerosol generating product to be effectively cooled, avoiding a high aerosol inlet temperature when the user inhales. Furthermore, the existence of this gap can serve as a channel for aerosol flow, preventing the problem of excessive suction resistance in the quaternary aerosol generating product. In other words, in this embodiment, by providing a filter section 10, the user can inhale the quaternary aerosol generating product through the filter section 10. At least one section downstream of the smoke-generating section 40 is formed by the aggregation of pleated fiber sheets, thereby creating gaps between the pleated fiber sheets 001 to cool the aerosol. This prevents the aerosol inlet temperature from being too high when the user inhales the quaternary aerosol generating product, and also avoids excessive suction resistance of the aerosol generating product. In other words, this embodiment effectively reduces the aerosol inlet temperature and the suction resistance of the quaternary aerosol generating product.

[0036] It should be noted that the outer shell can be made of cardboard tube, or it can be made of cigarette paper.

[0037] It should also be noted that the pleated fiber sheet 001 can be made from natural plants. For example, the pleated fiber sheet 001 can be made from tobacco substrate, or it can be made from other plants.

[0038] In addition, in the embodiments of this application, "gathering" can be regular or irregular winding, or it can be repeated folding, or it can be squeezed from all sides.

[0039] Additionally, in the embodiments of this application, such as Figure 4 and Figure 8 As shown, the second functional section may include a support section 30 or a sealing section 50. Additionally, the first functional section 20 may be a cooling section. Specifically, when the second functional section includes the support section 30, the support section 30 is located at the end of the smoke-generating section 40 facing the first functional section 20, i.e., the support section 30 is located between the first functional section 20 and the smoke-generating section 40; when the second functional section includes the sealing section 50, the sealing section 50 is located at the end of the smoke-generating section 40 away from the first functional section 20.

[0040] In addition, in the embodiments of this application, the pleated fiber sheet 001 can be pleated paper.

[0041] In addition, the filter section 10 mainly serves to transport and filter aerosols, allowing them to enter the user's mouth. The filter section 10 can be filled with filter material, including but not limited to paper filter rods, cotton filter rods, cellulose acetate, and cellulose propionate. The cotton filter rod can be formed from at least one of PP, PA, PET, non-woven fabric, and integral cotton.

[0042] In some embodiments, the first functional segment 20 and the support segment 30 can be an integral structure, that is, the first functional segment 20 and the support segment 30 are combined into one. Of course, the first functional segment 20 and the support segment 30 can also be two segments. In this regard, the embodiments of this application do not limit it.

[0043] Furthermore, the first functional segment 20 may be formed only by gathering pleated fiber sheets 001; the support segment 30 may be formed only by gathering pleated fiber sheets 001; the smoke-generating segment 40 may be formed only by gathering pleated fiber sheets 001; the first functional segment 20 and the support segment 30 may be formed by gathering pleated fiber sheets 001; the first functional segment 20 and the smoke-generating segment 40 may be formed by gathering pleated fiber sheets 001; the support segment 30 and the smoke-generating segment 40 may be formed by gathering pleated fiber sheets 001; and the first functional segment 20, the support segment 30, and the smoke-generating segment 40 may all be formed by gathering pleated fiber sheets 001.

[0044] In some embodiments, the smoke-generating section 40 is formed by aggregating a first fiber sheet, the first fiber sheet comprising tobacco material.

[0045] When the smoke-generating section 40 is formed by the aggregation of the first fiber sheet, in order to ensure that the smoke-generating section 40 can generate smoke, the first fiber sheet includes tobacco material, that is, the first fiber sheet is made of tobacco material. Thus, once the smoke-generating section 40 is heated, the smoke-generating section 40 can generate aerosol, so that when the user uses the quaternary aerosol generated product, the aerosol can enter the user's mouth, improving the user experience.

[0046] In some embodiments, the smoke-generating section 40 is not formed by the aggregation of the first fiber sheet. In this case, the smoke-generating section 40 may contain tobacco particles in particulate form. The tobacco particles may include several mixtures such as tobacco powder, PG, VG, tobacco extract, flavorings, adhesives, cellulose, nicotine or nicotine salts, etc. The mixture is made into small particles of different shapes by a granulation process to form tobacco particles.

[0047] Specifically, when preparing tobacco pellets, tobacco powder, blueberry and other plant powders can be selected, and smoke-generating agents, nicotine, PG solvent, plant extracts and flavorings can be added. The proportion of these ingredients should not exceed the proportion of solid plant powder. After mixing, an adhesive is added, the mixture is stirred, granulated, and dried. The drying temperature should not exceed 105°C to obtain tobacco pellets.

[0048] Additionally, in some embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, the second functional section is a sealing section 50; the sealing section 50 is connected to the end of the smoke-generating section 40 away from the first functional section 20, and the sealing section 50 is formed by the gathering of pleated fiber sheets 001. By setting the sealing section 50, the sealing section 50 can effectively seal the smoke-generating section 40, preventing the leakage of tobacco particles from the smoke-generating section 40. Furthermore, it allows the gap between two adjacent pleated fiber sheet layers in the radial direction of the quaternary aerosol generating product to serve as a gas channel. Thus, when the user inhales the quaternary aerosol generating product, gas can flow through this gas channel to the smoke-generating section 40, facilitating the generation of aerosols in the smoke-generating section 40.

[0049] In addition, such as Figures 1-2 , Figures 4-7 As shown, when the quaternary aerosol product does not include the sealing section 50, a sealing element 41 can be provided at the end of the smoke-generating section 40 away from the support section 30. The sealing element 41 covers the end of the smoke-generating section 40 away from the support section 30 to prevent the leakage of tobacco particles in the smoke-generating section 40. The sealing element 41 includes, but is not limited to, mesh cloth, mesh lines, sealing paper, etc.

[0050] In some embodiments, at least one of the filter section 10, the first functional section 20, and the second functional section is provided with a fragrance carrier 60. The fragrance carrier 60 is used to generate aroma-producing substances to mix with the aerosol generated by the smoke-generating section 40. With this arrangement, when a user inhales the quaternary aerosol-generated product, the aerosol or gas can flow through the fragrance carrier 60, allowing the aroma of the fragrance carrier 60 to enter the user's mouth along with the aerosol, thus allowing the user to experience different flavors. In other words, by providing the fragrance carrier 60, it can generate aroma-producing substances to mix with the aerosol generated by the smoke-generating section 40, enriching the aroma of the quaternary aerosol-generated product and thus improving the user experience of using the quaternary aerosol-generated product.

[0051] It should be noted that the fragrance-carrying substance 60 can be provided only in the filter section 10, only in the first functional section 20, only in the support section 30, or only in the sealing section 50. Of course, the fragrance-carrying substance 60 can also be provided in both the first functional section 20 and the support section 30, in both the filter section 10 and the first functional section 20, in both the support section 30 and the sealing section 50, in all three sections (filter section 10, first functional section 20, support section 30, and sealing section 50). This application does not limit the specific embodiment to this method.

[0052] In some embodiments, the fragrance carrier 60 may include at least one of fragrance-carrying beads, fragrance-carrying core threads, fragrance-carrying particles, and fragrance-carrying gel beads. Fragrance-carrying beads, fragrance-carrying core threads, fragrance-carrying particles, and fragrance-carrying gel beads are readily available and relatively inexpensive, and can reduce the cost of quaternary aerosol-generated products while enriching their fragrance.

[0053] It should be noted that the fragrance-carrying substance 60 may consist only of fragrance-carrying capsules; fragrance-carrying substance 60 may consist only of fragrance-carrying core wire; fragrance-carrying substance 60 may consist only of fragrance-carrying particles; fragrance-carrying substance 60 may consist only of fragrance-carrying gel beads; of course, fragrance-carrying substance 60 may also include fragrance-carrying capsules and fragrance-carrying particles, in which case the fragrance-carrying capsules and fragrance-carrying particles can be mixed; fragrance-carrying substance 60 may also include fragrance-carrying capsules, fragrance-carrying particles, and fragrance-carrying gel beads, in which case the fragrance-carrying capsules, fragrance-carrying particles, and fragrance-carrying gel beads can be mixed. Regardless of whether the fragrance-carrying gel beads are mixed with the fragrance-carrying capsules, or whether the fragrance-carrying capsules, fragrance-carrying gel beads, and fragrance-carrying particles are mixed, it is a physical mixing process, meaning that no chemical reaction occurs between these components.

[0054] In some embodiments, the first functional segment 20 and the second functional segment, other than being formed by winding fiber sheets, include a frame structure 100. The frame structure 100 includes a first frame 101, a second frame 102, and a plurality of connecting strips 103. The first frame 101 and the second frame 102 are spaced apart along the axial direction of the quaternary aerosol product. The plurality of connecting strips 103 are all located between the first frame 101 and the second frame 102, and each connecting strip 103 connects the first frame 101 and the second frame 102 respectively. The plurality of connecting strips 103 are spaced apart along the circumferential direction of the quaternary aerosol product.

[0055] Since the first frame 101 and the second frame 102 are spaced apart along the axial direction of the quaternary aerosol product, and multiple connecting strips 103 are located between the first frame 101 and the second frame 102, with each connecting strip 103 connecting both the first frame 101 and the second frame 102, a gap can be formed between adjacent frames, and the frames have a large internal space. Therefore, when the user inhales the quaternary aerosol product, the internal space of the frames can serve as a gas channel, allowing the aerosol to flow easily into the user's mouth. Furthermore, the first frame 101 and the second frame 102 can serve as a support structure, supporting the multiple connecting strips 103 to form the frame structure 100.

[0056] It should be noted that, in the first functional segment 20, the support segment 30, and the sealing segment 50, when the first functional segment 20 is formed by gathering pleated fiber sheets 001, at least one of the support segment 30 and the sealing segment 50 includes a frame structure 100. For example, the support segment 30 includes a frame structure 100, and the sealing segment 50 includes a frame structure 100; or both the support segment 30 and the sealing segment 50 include a frame structure 100. Similarly, when the support segment 30 is formed by gathering pleated fiber sheets 001, at this time, the first functional segment 20... At least one of the functional segment 20 and the sealing segment 50 includes a frame structure 100; when the sealing segment 50 is formed by gathering pleated fiber sheets 001, at least one of the first functional segment 20 and the support segment 30 includes a frame structure 100; when the first functional segment 20 and the support segment 30 are formed by gathering paper from pleated fiber sheets 001, the sealing segment 50 includes a frame structure 100; when the first functional segment 20 and the sealing segment 50 are formed by gathering pleated fiber sheets 001, the support segment 30 includes a frame structure 100.

[0057] It should also be noted that the shapes of the first frame 101 and the second frame 102 can be set according to actual needs. For example, the first frame 101 and the second frame 102 can both be annular, or the first frame 101 and the second frame 102 can both be hexagonal. In this regard, the embodiments of this application do not limit the scope of the application.

[0058] Additionally, in some embodiments, such as Figure 10 As shown, at least one section of the outer casing between the filter section 10 and the smoke-generating section 40 is provided with a cooling hole 201, which is connected to the first functional section 20.

[0059] Since at least one section of the outer shell between the filter section 10 and the smoke-generating section 40 has a cooling hole 201, and the cooling hole 201 is connected to the first functional section 20, when the user inhales the quaternary aerosol to generate the product, the cooling hole 201 can allow the gas outside the quaternary aerosol product to enter the interior of the first functional section 20, thereby ensuring that the first functional section 20 is effectively cooled.

[0060] It should be noted that there is a first functional section 20 and a second functional section between the filter section 10 and the smoke-generating section 40. The cooling hole 201 can be opened only in the outer shell corresponding to the first functional section 20, or only in the outer shell corresponding to the second functional section, or both the outer shell corresponding to the first functional section 20 and the outer shell corresponding to the second functional section can be opened with cooling holes 201.

[0061] In some embodiments, such as Figure 10 As shown, at least one section between the filter section 10 and the smoke-generating section 40 is a cavity 200 enclosed by the outer shell, and the cooling hole 201 is opened at the part of the outer shell corresponding to the cavity 200.

[0062] With this design, when the user aspirates the quaternary aerosol to generate the product, once the aerosol enters the cavity 200, the larger space of the cavity 200 can effectively cool the aerosol. Furthermore, the cooling hole 201 allows external gas to enter the cavity 200, further cooling the aerosol within it. In other words, by setting up the cavity 200, it helps cool the aerosol and lowers the inlet temperature of the aerosol entering the user's mouth.

[0063] It should be noted that, in the first functional segment 20, the support segment 30, and the sealing segment 50, when the first functional segment 20 is formed by gathering pleated fiber sheets 001, at least one of the support segment 30 and the sealing segment 50 includes a cavity 200. For example, the support segment 30 includes a cavity 200, and the sealing segment 50 includes a cavity 200; or both the support segment 30 and the sealing segment 50 include cavities 200. Similarly, when the support segment 30 is formed by gathering pleated fiber sheets 001, at this time, the first functional segment 20... At least one of the functional segment 20 and the sealing segment 50 includes a cavity 200; when the sealing segment 50 is formed by gathering together pleated fiber sheets 001, at least one of the first functional segment 20 and the support segment 30 includes a cavity 200; when the first functional segment 20 and the support segment 30 are formed by gathering together pleated fiber sheets 001, the sealing segment 50 includes a cavity 200; when the first functional segment 20 and the sealing segment 50 are formed by gathering together pleated fiber sheets 001, the support segment 30 includes a cavity 200.

[0064] Furthermore, the number of cooling holes 201 corresponding to the cavity wall of the cavity 200 can be set according to actual needs. For example, the number of cooling holes 201 can be 4, or for another example, the number of cooling holes 201 can be 6. The specific number of cooling holes 201 is not limited in this embodiment.

[0065] In some embodiments, the cavity 200 may be filled with a substance, which may include, but is not limited to, cooling materials, paper materials, cotton materials, etc. Specifically, the substance may include cotton filter rods, cellulose acetate, cellulose propionate, silicone filter rods, etc., wherein the cotton filter rods include, but are not limited to, PP, PA, PET, non-woven fabric, and integrated cotton.

[0066] In addition, in some embodiments, if the cavity 200 is filled with a substance, an air passage 300 can be provided in the substance so that the aerosol can flow through the air passage 300 to the filter section 10.

[0067] Additionally, in some embodiments, such as Figure 8 As shown, at least one of the first functional section 20 and the second functional section is provided with an airway 300. The airway 300 connects the smoke-generating section 40 and the filter section 10, and the airway 300 contains a flavor-carrying capsule. With this configuration, once the user inhales the quaternary aerosol-generated product, the aerosol can flow into the airway 300, then into the filter section 10, and finally into the user's mouth. In other words, by providing the airway 300, the aerosol can be easily delivered to the user's mouth. Furthermore, the presence of a flavor-carrying capsule within the airway 300 allows the aerosol to flow through the capsule when the user inhales the quaternary aerosol-generated product, thus enhancing the taste of the product.

[0068] Furthermore, the air passage 300 can extend along the axial direction of the quaternary aerosol-generated article. The shape of the cross-section of the air passage 300 can be set according to actual needs. For example, the cross-section of the air passage 300 can be a pentagon; a square; a rectangle; a triangle; a hexagon; or an octagon. The specific shape of the cross-section of the air passage 300 is not limited in this embodiment. The cross-section of the air passage 300 refers to a plane perpendicular to the axial direction of the quaternary aerosol-generated article.

[0069] It should be noted that the airway 300 can be set only in the first functional section 20, or only in the support section 30, or in both the first functional section 20 and the support section 30. In this case, the airway 300 in the first functional section 20 is connected to the airway 300 in the support section 30.

[0070] Additionally, in some embodiments, such as Figure 8 As shown, the smoke-generating section 40 contains smoke particles 401. The end of the smoke-generating section 40 facing away from the second functional section is covered with a shielding layer 70. The shielding layer 70 has multiple mesh openings, the diameter of which is smaller than the diameter of the smoke particles 401. With this design, when the user uses quaternary aerosol to generate products, the shielding layer 70 can effectively shield the smoke particles 401 in the smoke-generating section 40, thereby preventing the smoke particles 401 from flowing into the support section 30 or the first functional section 20. In other words, by setting the shielding layer 70, the leakage of smoke particles 401 from the smoke-generating section 40 can be effectively prevented.

[0071] In addition, in some embodiments, when the support section 30 includes a frame structure 100, the first frame 101 faces the smoke-generating section 40, and the second frame 102 is away from the smoke-generating section 40. Covering elements can be provided in both the first frame 101 and the second frame 102.

[0072] It should be noted that the shielding layer 70 may include, but is not limited to, mesh fabric, mesh lines, etc.

[0073] like Figure 11 As shown, this application provides an aerosol generation system, which includes an aerosol generation device 400 and a quaternary aerosol generation product in any of the above embodiments; the smoke generation section 40 is located in the aerosol generation device 400, and the aerosol generation device 400 is used to heat the smoke generation section 40.

[0074] The aerosol generating device 400 includes a device body 410 and a heating element 420. The device body 410 has a receiving space, and the heating element 420 is located in the receiving space. The smoke generating section 40 can be placed in the receiving space and heated by the heating element 420.

[0075] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.
