[0002] Heat Not Burning (HNB) products are a type of aerosol-generating products that heat an aerosol-generating substrate (treated plant leaf products) but do not cause it to burn. Heat Not Burning products generate aerosols by heating the aerosol-generating substrate at high temperatures, but the temperature is not high enough to cause the aerosol-generating substrate to burn, thereby forming the aerosol required by the user.

[0035] In this application, the "extension direction" orientation or position relationship is based on the attached Figure 2 It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0036] An embodiment of the present application provides an aerosol generating product, see Figure 2 and Figure 3 , including a medium section 10, a filtering section 40 and a cooling section 20.

[0037] The medium section 10 is the area where the aerosol generating product is installed with the aerosol generating substrate. The aerosol generating substrate can be heated in the medium section 10 to produce aerosol. During the inhalation process, when the external airflow passes through the medium section 10, the aerosol can flow with the airflow.

[0038] The filter section 40 can filter and shape the aerosol, aggregate the aerosol, reduce the phenomenon of aerosol dispersion, and filter out the debris generated by the aerosol generation matrix during heating, thereby improving the user experience.

[0039] The cooling section 20 has an air flow channel 20 a . The cooling section 20 is disposed between the medium section 10 and the filter section 40 . A first air flow path is formed between the medium section 10 and the filter section 40 , at least flowing through the air flow channel 20 a .

[0040] Specifically, during the suction process, the airflow will pass through the medium segment 10, the airflow channel 20a and the filter segment 40 in sequence.

[0041] See also Figure 3 The cooling section 20 includes a heat conducting member 21 and a main body 22 having an air flow channel 20a. The main body 22 has an outer surface and an inner surface located in the air flow channel 20a. The heat conducting member 21 is provided on at least one of the outer surface of the main body 22 and the inner surface of the main body 22.

[0042] Specifically, see Figure 8 and Fig. 9The heat conducting member 21 may be provided on only the outer surface of the main body 22 , or on the inner surface of the main body 22 , or on both the outer surface and the inner surface of the main body 22 .

[0043] It should be noted that, depending on different actual situations, the main body 22 and the heat conducting member 21 may be an integrally formed structure, or they may be separate structures.

[0044] In addition, according to actual conditions, in addition to the medium section 10, the cooling section 20 and the filtering section 40, the aerosol generating product may also be provided with other sections, such as a supporting section 30. The supporting section 30 is provided between the cooling section 20 and the filtering section 40, which can enable the aerosol generating product to have better supporting performance, thereby making the structure more stable.

[0045] The aerosol generating product of the embodiment of the present application comprises a medium section 10, a filter section 40 and a cooling section 20 having an air flow channel 20a. The cooling section 20 is arranged between the medium section 10 and the filter section 40. A first air flow path at least flowing through the air flow channel 20a is formed between the medium section 10 and the filter section 40. At least one of the outer surface of the main body 22 of the cooling section 20 and the inner surface of the main body 22 is provided with a heat conductive member 21. Thus, by providing the heat conductive member 21, the surface area of ​​the cooling section 20 can be greatly increased. In the case where the outer surface of the main body 22 is provided with the heat conductive member 21, the outer surface area of ​​the cooling section 20 in contact with the external environment can be greatly increased, so as to accelerate the energy exchange between the cooling section 20 and the external environment, thereby improving the heat dissipation rate of the cooling section 20 to the aerosol in the air flow channel 20a, and thus achieving a better cooling effect. When the heat conducting member 21 is provided on the inner surface of the main body 22, the contact area between the cooling section 20 and the aerosol in the airflow channel 20a can be increased to accelerate the energy exchange between the cooling section 20 and the aerosol, so that the cooling section 20 can transfer heat to the external environment, thereby achieving a better cooling effect. It can be understood that when the heat conducting member 21 is provided on both the outer surface and the inner surface of the main body 22, the surface area of ​​the cooling section 20 can be further increased, thereby further improving the cooling effect of the cooling section 20.

[0046] The heat dissipation effect of the cooling section 20 is related to the number, arrangement and specific shape of the heat conducting member 21. The arrangement and number of the heat conducting member 21 are not limited. For example, the heat conducting member 21 is a heat dissipation fin.

[0047] For example, see Figures 5 to 9 At least one of the outer surface of the main body 22 and the inner surface of the main body 22 is provided with a plurality of heat conducting members 21 at intervals along the circumferential direction, and each heat conducting member 21 extends along the extension direction of the temperature reduction section 20 .

[0048] Specifically, multiple heat-conducting members 21 may be arranged at intervals on the circumference of the outer surface of the main body 22, multiple heat-conducting members 21 may be arranged at intervals on the circumference of the inner surface of the main body 22, or multiple heat-conducting members 21 may be arranged at intervals on the circumference of the outer surface and the inner surface of the main body 22. The heat-conducting members 21 are arranged at intervals to further increase the surface area of ​​the cooling section 20, thereby further improving the heat dissipation effect of the cooling section 20.

[0049] It should be noted that the structural shapes of the heat conducting member 21 disposed on the outer surface of the main body 22 and the inner surface of the main body 22 may be the same or different.

[0050] For example, see Figure 6 The heat-conducting member 21 includes a first heat-conducting member 211 disposed on the inner surface of the main body 22 , and the first heat-conducting member 211 is a rectangular body.

[0051] For example, see Figure 5 The first heat conductor 211 has a first arc surface 211a and a second arc surface 211b bent in a direction approaching each other on both sides, one side of the first arc surface 211a and the second arc surface 211b is located on the inner surface of the main body 22, and the other side of the first arc surface 211a and the second arc surface 211b has a common edge facing away from the main body 22.

[0052] Specifically, the first heat-conducting member 211 is an arc-shaped heat-conducting member. The first heat-conducting member 211 adopts an arc surface with a convex middle portion to increase the surface area of ​​the first heat-conducting member 211, so as to further improve the heat-conducting effect. In addition, the first arc surface 211a and the second arc surface 211b are bent in a direction close to each other, and the side edges of the first arc surface 211a and the second arc surface 211b away from the main body 22 overlap, that is, a common edge, thereby facilitating energy exchange between the first heat-conducting member 211 and the aerosol.

[0053] For example, see Figure 7 The first heat conducting member 211 has a first end 2111 disposed on the inner surface of the main body 22 , and a second end 2112 opposite to the first end 2111 , and the width of the second end 2112 gradually decreases in a direction away from the first end 2111 .

[0054] Specifically, the end of the first heat-conducting member 211 connected to the inner surface of the main body 22 is the first end 2111, and the end of the first heat-conducting member 211 away from the main body 22 is the second end 2112. The shape of the first end 2111 is not limited, and it can be a structure of equal width, such as a rectangular body. The cross-sectional width of the second end 2112 gradually decreases in the direction away from the first end 2111. For example, the second end 2112 is a triangular prism structure. The second end 2112 adopts a structural form with a gradually decreasing width, which can facilitate the flow of aerosol in the airflow channel 20a.

[0055] In one embodiment, please refer to Figure 8 and Fig. 9 The heat conducting member 21 includes a second heat conducting member 212 disposed on the outer surface of the main body 22, and the width of the second heat conducting member 212 gradually decreases in a direction away from the main body 22. Thus, the second heat conducting member 21221 can facilitate energy exchange with the external environment.

[0056] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The aerosol generating product includes a tube body 50 having a tube cavity and an air inlet hole 50a, the medium section 10, the cooling section 20 and the filter section 40 are sequentially arranged in the tube cavity, and at least a part of the main body 22 is spaced apart from the tube body 50 to form a spacing space 20b, and the spacing space 20b is respectively connected to the air inlet hole 50a and the airflow channel 20a to form a second airflow path between the air inlet hole 50a and the filter section 40, flowing through the spacing space 20b and the airflow channel 20a.

[0057] Specifically, the air inlet 50a is connected to the tube cavity. The aerosol generating product includes two airflow paths. By providing two airflow paths, the air intake of the aerosol generating product can be increased, which can facilitate the user to inhale.

[0058] The air inlet 50a is an air inlet for the external air flow to flow along the second air flow path. The specific location and number of the air inlet 50a are not limited. For example, a plurality of air inlet 50a are arranged at intervals on the side wall of the tube body 50.

[0059] The main body 22 may be spaced apart from the tube body 50 in its entire region, or may be spaced apart from the tube body 50 in only a portion of its region.

[0060] In fact, the bottom end of the aerosol generating article also has an air flow inlet for the ambient air flow to flow along the first air flow path.

[0061] In a specific embodiment, a heat conducting member 21 is disposed on the outer surface of the main body 22 and is located in the separation space 20 b.

[0062] That is, at least part of the heat-conducting member 21 is disposed in the spacing space 20b. During the inhalation process, after the cooling section 20 exchanges energy with the aerosol, at least part of the heat can be transferred to the spacing space 20b through the heat-conducting member 21 disposed in the spacing space 20b. Thus, the external airflow flowing into the second airflow path can be preheated, thereby reducing the liquid seepage phenomenon caused by condensation at the medium section 10 and the cooling section 20.

[0063] In one embodiment, the cooling section 20 is formed by injection molding of at least one of graphite and metal materials and an organic polymer material.

[0064] Specifically, the material of the temperature-lowering section 20 may include graphite, metal material and organic polymer material, or may only include graphite and organic polymer material, or may only include metal material and organic polymer material.

[0065] Injection molding refers to the process of mixing organic polymer materials with graphite and / or metal materials and molding them in one piece through injection molding, extrusion, and pressing. Thus, the cooling section 20 can have a higher thermal conductivity and thus a better heat dissipation effect.

[0066] The specific type of the metal material can be determined according to actual conditions. For example, the metal material includes at least one of iron, aluminum and copper. In other words, the metal material can include one or more of iron, aluminum and copper.

[0067] In addition, the organic polymer material includes at least one of fiber paper, silica gel, polylactic acid material (PLA), and polyadipate material (PBAT). In other words, the organic polymer material can be one or more of the above materials.

[0068] It should be noted that the structure of the cooling section 20 itself has micropores. During the suction process, a "liquid film" will be formed on the inner surface of the main body 22, which can adsorb the aerosol macromolecules in the air flow channel 20a, thereby reducing the "granular feeling" during the user's suction process, thereby improving the user's experience.

[0069] The ratio of the surface area of ​​the heat conducting member 21 to the surface area of ​​the cooling section 20 should be within an appropriate range and should not be too small to avoid poor heat dissipation of the cooling section 20. It should also not be too large to prevent the heat conducting members 21 from being too densely arranged to affect the efficiency of energy exchange between the cooling section 20 and the aerosol or the external environment.

[0070] Exemplarily, the surface area of ​​the heat conducting member 21 is not less than 40% of the surface area of ​​the temperature reducing section 20 and not more than 80% of the surface area of ​​the temperature reducing section 20, such as 40%, or 60%, or 70%, or 80%.

[0071] In one embodiment, the thermal conductivity of the cooling section 20 is not less than 2700 W / (mK) and not more than 5300 W / (mK). The cooling section 20 has a high thermal conductivity, so it can quickly transfer the heat of the aerosol to the external environment. For example, the thermal conductivity of the cooling section 20 is 2700 W / (mK) or 5300 W / (mK).

[0072] In a specific embodiment, the temperature reduction section 20 is provided with a plurality of heat conducting members 21 only on the inner surface of the main body 22, and the surface area of ​​the heat conducting members 21 is not less than 40% of the surface area of ​​the temperature reduction section 20, and not more than 70% of the surface area of ​​the temperature reduction section 20. The thermal conductivity of the temperature reduction section 20 is not less than 3200 W / (mK) and not more than 4500 W / (mK), such as 3200 W / (mK), 4000 W / (mK) or 4500 W / (mK).

[0073] In a specific embodiment, a plurality of heat conducting members 21 are respectively disposed on the inner surface and the outer surface of the main body 22, and the surface area of ​​the heat conducting member 21 is not less than 60% of the surface area of ​​the cooling section 20, and not more than 80% of the surface area of ​​the cooling section 20. The thermal conductivity of the cooling section 20 is not less than 3700 W / (mK) and not more than 4700 W / (mK), such as 3700 W / (mK), 4200 W / (mK) or 4700 W / (mK).
