[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0030] As shown in Figures 1, 2 and 8, an aerosol product 10 in a preferred embodiment of the present invention includes a solid smoke-generating segment 1, a sieving segment 2, and a paper tube 3. The solid smoke-generating segment 1 and the sieving segment 2 are spaced apart in the paper tube 3, and a cooling section 4 is formed between the solid smoke-generating segment 1 and the sieving segment 2. The cooling section 4 has an axially extending airway 411 that can temporarily store the aerosol generated by the solid smoke-generating segment 1.

[0031] Furthermore, the solid smoking segment 1 includes a columnar matrix body 11, on which micropores are scattered. The matrix body 11 includes a downstream end A and an upstream end B located at its axial ends, and the downstream end is opposite to the screening section 2, wherein the downstream end A and the upstream end B are named with reference to the aerosol flow direction. During the inhalation process, the aerosol generated by the solid smoking segment 1 is transported from upstream to downstream, the downstream end A is the near-lip end, and the upstream end B is the far-lip end.

[0032] Here, the paper tube 3 is a cardboard tube. Unlike the traditional method of using rolling paper, this embodiment uses the paper tube 3 as a connecting member of the aerosol product 10. At the same time, the solid smoke-generating segment 1 is an independent columnar segment and does not require filling. When assembling the aerosol product 10, it is only necessary to install the solid smoke-generating segment 1 and the sieving segment 2 into the two ends of the paper tube 3 respectively. Therefore, the manufacturing process of the aerosol product 10 is simplified and the manufacturing cost is reduced.

[0033] The matrix body 11 is provided with an air flow hole 12 extending along its axial direction. The air flow hole 12 at least passes through the downstream end A. The micropores are connected to each other and the air flow hole 12 to collect the aerosol in the micropores into the air flow hole 12 .

[0034] A through hole 31 is provided on the side wall of the paper tube 3 corresponding to the cooling part 4, connecting the air flow hole 12 and the air channel 411 between the screening section 2. When the user inhales, the external air can enter the cooling part 4 through the through hole 31 and mix with the aerosol in the cooling part 4 to reduce the temperature of the aerosol. The size of the through hole 31 can be set according to demand to adjust the amount of air entering to meet the cooling demand of reducing the temperature to an appropriate temperature, so as to conform to the user's inhalation habits and avoid the aerosol temperature being too high and burning the mouth.

[0035] Preferably, a plurality of through holes 31 are distributed around the side wall of the paper tube 3 corresponding to the cooling portion 4, so that external air can flow into the cooling portion 4 from different directions, so that the air and aerosol can be fully mixed, thereby improving the uniformity of cooling.

[0036] In addition, the cooling part 4 can also play the role of pre-storing aerosols. There will be a pause after the user's last inhalation. During this process, a part of the aerosol between the micropores of the matrix body 11 will naturally gather in the airflow holes 12 and be temporarily stored in the cooling part 4. During the puffing interval, it will naturally gather in the cooling part for temporary storage, which assists in cooling and increasing the smoke concentration. When the user smokes next time, the aerosol stored in the cooling part 4 will be inhaled first, and the new aerosol generated by the matrix body 11 will flow into the cooling part 4 for storage again with the airflow, which can also play the role of cooling the aerosol. During the puffing cycle, the aerosol generated by the solid smoking segment 1 can be prevented from being repeatedly heated and affecting the taste.

[0037] At the same time, in order to prevent the pre-stored aerosol from overflowing during the residence stage, the distance from the through hole 31 to the sieving section 2 can be made smaller than the distance from the through hole 31 to the solid smoking section 1, and the distance from the through hole 31 to the matrix body 11 can be made as large as possible. The aerosol stored between the through hole 31 and the solid smoking section 1 is not easy to overflow, and the air can be mixed with the pre-stored aerosol when flowing to the sieving section 2 and then flow to the sieving section 2.

[0038] Typically, the cross-section of the airflow hole 12 can be circular, elliptical, polygonal, or irregular. There can be one airflow hole 12, which can be a through hole or a blind hole. In other embodiments, there can be more than one airflow hole 12, wherein all airflow holes 12 can be through holes, all airflow holes 12 can be blind holes, or the matrix body 11 can be provided with both through holes 12 and blind holes 12. In the heat-not-burn aerosol product of this embodiment, the downstream end A of the airflow hole 12 opens opposite the sieving section 2, allowing the aerosol to flow from the airflow hole 12 to the cooling section 4 and the sieving section 2.

[0039] For example, as shown in FIG3 , the porosity of the micropores is 20%-80%, and the pore size is 50nm-20μm. The micropores are connected to each other and to the airflow holes 12 to collect the aerosols in the micropores to the airflow holes 12. After the solid smoking segment 1 is heated, the aerosol generated by the heating can enter the adjacent airflow holes 12 through the micropores and be collected. The aerosols generated at different positions flow into the cooling part 4 and mix to make the aerosol more uniform. Then, they flow from the airflow holes 12 to the cooling part 4. The cooling part 4 can play the role of centralized storage and cooling of the aerosols. When the user smokes, he will first inhale the aerosol in the cooling part 4. After the aerosol in the cooling part 4 is sucked away, the newly generated aerosol will flow back into the cooling part 4, which can effectively prevent the aerosol from flowing directly into the user's mouth, avoid burning the mouth, and at the same time, improve the taste of the aerosol.

[0040] Specifically, the solid smoking segment 1 is made by mixing tobacco fibers or other plant fibers, and then compressing and demolding to form an integrally formed solid smoking segment 1 .

[0041] In the first embodiment, as shown in FIG4 , the airflow hole 12 extends from the downstream end A to the upstream end B. The cross-sections of the airflow hole 12 at different axial positions include two or more external dimensions. As shown in the figure, the external dimensions here can refer to specific shapes, such as a circle at one end and a square at the other. In other embodiments, the cross-sectional shapes of the holes at different axial positions of the same airflow hole 12 can be any of a circle, a polygon, an ellipse, a polygonal star, an irregular shape, etc., to form the airflow hole 12, such as a square at one end and an ellipse at the other, or a polygon at one end and a polygonal star at the other. As shown in the figure, the term "different dimensions" can also refer to the same shape, allowing the airflow hole 12 to have different cross-sectional dimensions in the axial direction, such as a stepped airflow hole 12. When the aerosol enters the airflow hole 12 and flows, the aerosol flow rate can also change due to the change in the size of the airflow hole 12, thereby changing the aerosol flow rate within the airflow hole 12, mixing the aerosol, and improving the aerosol uniformity.

[0042] In the second embodiment, as shown in FIG5 , part of the air flow hole 12 may penetrate from the downstream end A to the upstream end B, and the cross-sectional shape of the air flow hole 12 gradually decreases from the downstream end A toward the upstream end B, forming a conical channel with a larger downstream end and a smaller upstream end.

[0043] In the third embodiment, as shown in FIG6 , part of the air flow hole 12 may penetrate from the downstream end A to the upstream end B, and the cross-sectional shape of the air flow hole 12 gradually increases from the downstream end A toward the upstream end B, forming a tapered channel with a small downstream end and a large upstream end.

[0044] In the fourth embodiment, as shown in Figure 7, part of the air flow hole 12 runs through the downstream end A to the upstream end B, and the cross-sectional shape of the part of the air flow hole 12 gradually decreases from the downstream end A to the upstream end B, and the cross-sectional shape of the part of the air flow hole 12 gradually increases from the downstream end A to the upstream end B.

[0045] Correspondingly, the airflow holes 12 of the various solid smoking segments 1 described above are identical, including their cross-sectional shapes and sizes. In other embodiments, the airflow holes 12 include two or more types, and the cross-sectional dimensions of the different types of airflow holes 12 vary. It is understood that the cross-sectional dimensions of the different types of airflow holes 12 may also vary, or the cross-sectional dimensions and dimensions of the different types of airflow holes 12 may vary, thereby forming a variety of airflow holes 12.

[0046] The outer surface of the matrix body 11 can be cylindrical or flat, such as ellipsoidal or square, to facilitate the production of aerosol products of corresponding shapes for users to hold in their mouths and inhale. During the use of the aerosol product, the aerosol is mixed and cooled to an appropriate temperature, with a more uniform taste, and reduced disturbances in the flow of the aerosol after generation.

[0047] In the above embodiment, the cooling portion 4 is a hollow cavity. That is, after the solid smoke generating segment 1 and the screening segment 2 are respectively installed at both ends of the paper tube 3, the solid smoke generating segment 1, the screening segment 2, and the paper tube 3 enclose an airway 411, without the need for additional components to form a cavity for storing aerosol.

[0048] It can be understood that, as shown in Figure 8, the aerosol product may also include a cooling component 41 arranged between the solid smoke-generating section 1 and the screening section 2. The cooling component 41 is provided with an air channel 411 connecting the air flow holes 12, the screening section 2, and the through hole 31. The air channel 411 can store aerosol and allow the aerosol to flow toward the screening section 2. External gas flows in through the through hole 31 and mixes with the aerosol to cool the aerosol.

[0049] In some embodiments, the air channel 411 may include one or more air channels. As shown in FIG9A , some of the air channels 411 may be located on the periphery of the cooling element 41, forming grooves on the outer peripheral surface of the cooling element 41. Some of the air channels 411 may also be through holes within the cooling element 41. Alternatively, air channels 411 may be provided on both the outer peripheral surface and the center of the cooling element 41. Alternatively, as shown in FIG9B , all air channels 411 may be through holes within the cooling element 41. When there are multiple air channels 411, air channels 411 may be provided in the center and on all four sides of the cooling element 41.

[0050] It can be understood that the above technical features can be used in any combination without limitation.

[0051] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
