Description

Technical Field

[0001] This application relates to the technical field of atomization, and particularly to aerosol generating products.

Background Art

[0002] A heat-not-burning (HNB) product is a type of aerosol generating product that heats an aerosol generating substrate (processed plant leaf products) but does not burn it. The heat-not-burning product heats the aerosol generating substrate at a high temperature to generate an aerosol, but not at a temperature high enough to burn the aerosol generating substrate, so that the aerosol required by the user can be formed.

[0003] The temperature reduction section of the heat-not-burning product can adjust the temperature of the aerosol flowing out of the suction port to an appropriate temperature by lowering the temperature of the aerosol. Here, most of the temperature reduction section is a hot air cooling and condensing component, that is, the effect of lowering the aerosol temperature is achieved by solid heat transfer. However, in the related art, the temperature reduction section has a slow heat dissipation rate and a poor temperature reduction effect, resulting in a poor user experience.

Embodiments for Carrying Out the Invention

[0018] In the present application, the orientation or positional relationship of the "extending direction" is based on the orientation or positional relationship shown in FIG. 2. It should be understood that these orientation terms are only for facilitating the description of the present application and simplifying the description, and do not indicate or suggest that the specified device or component must have a specific orientation and must be configured and operated in a specific orientation, and thus should not be understood as a limitation to the present application.

[0019] One embodiment of the present application provides an aerosol generating product. Referring to FIGS. 2 and 3, the aerosol generating product includes a medium stage part 10, a filtering stage part 40, and a temperature reduction stage part 20.

[0020] Here, the medium stage part 10 is an area where an aerosol generating substrate is mounted on the aerosol generating product. The aerosol generating substrate can be heated in the medium stage part 10 to generate an aerosol. During suction, when an external air flow passes through the medium stage part 10, the aerosol can flow together with the air flow.

[0021] The filtering stage part 40 can filter and reshape the aerosol, collect the aerosol, reduce the divergence phenomenon of the aerosol, and can also filter the debris generated during the heating of the aerosol generating substrate, thereby improving the user experience.

[0022] The temperature reduction stage part 20 has an air flow passage 20a. The temperature reduction stage part 20 is provided between the medium stage part 10 and the filtering stage part 40, and at least a first air flow path flowing through the air flow passage 20a is formed between the medium stage part 10 and the filtering stage part 40.

[0023] Specifically, during suction, the airflow passes sequentially through the medium stage 10, the airflow passage 20a, and the filtration stage 40.

[0024] Referring to Figures 8 and 9, the cooling step 20 includes a heat conductive member 21 and a main body 22 having an airflow passage 20a. The main body 22 has an outer surface and an inner surface located within the airflow passage 20a, and the heat conductive member 21 is provided on at least one of the outer surface and the inner surface of the main body 22.

[0025] Specifically, referring to Figures 8 and 9, the heat conductive member 21 may be provided only on the outer surface of the main body 22, or on the inner surface of the main body 22, or on both the outer and inner surfaces of the main body 22.

[0026] It should be explained that, depending on the actual situation, the main body 22 and the heat conductive member 21 may be integrally molded, or they may be separate structures.

[0027] Furthermore, depending on the actual situation, in addition to the medium stage 10, the cooling stage 20, and the filtration stage 40, other stages, such as a support stage 30, may be provided in the aerosol-generating product. The support stage 30 is provided between the cooling stage 20 and the filtration stage 40 to provide good support performance for the aerosol-generating product, thereby making the structure more stable.

[0028] The aerosol generating product of the embodiment of the present invention comprises a medium stage 10, a filtration stage 40, and a cooling stage 20 having an airflow passage 20a. The cooling stage 20 is provided between the medium stage 10 and the filtration stage 40, and a first airflow path flowing through at least the airflow passage 20a is formed between the medium stage 10 and the filtration stage 40. A heat conductive member 21 is provided on at least one of the outer surface and inner surface of the main body 22 of the cooling stage 20. Therefore, by providing the heat conductive member 21, the surface area of ​​the cooling stage 20 can be significantly increased. When the heat conductive member 21 is provided on the outer surface of the main body 22, the outer surface area of ​​the cooling stage 20 that comes into contact with the external environment can be greatly increased, accelerating energy exchange between the cooling stage 20 and the external environment. This improves the rate of heat dissipation from the cooling stage 20 to the aerosol in the airflow passage 20a, and therefore, a good cooling effect can be achieved. When a heat conductive member 21 is provided on the inner surface of the main body 22, the contact area between the cooling step 20 and the aerosol in the airflow passage 20a can be increased, accelerating the energy exchange between the cooling step 20 and the aerosol, making it easier for the cooling step 20 to transfer heat to the external environment, and thus enabling a good cooling effect. Understandably, when a heat conductive member 21 is provided on both the outer and inner surfaces of the main body 22, the surface area of ​​the cooling step 20 can be further increased, and thus the cooling effect of the cooling step 20 can be further improved.

[0029] The heat dissipation effect of the cooling stage 20 is related to the number, installation method, and specific shape of the heat conduction members 21. Here, the installation method and number of heat conduction members 21 are not limited. For example, the heat conduction members 21 are heat dissipation fins.

[0030] For example, referring to Figures 5 to 9, a plurality of heat conductive members 21 are provided on at least one of the outer surface and inner surface of the main body 22 at intervals in the circumferential direction, and each heat conductive member 21 extends along the extending direction of the cooling step 20.

[0031] Specifically, multiple heat conductive members 21 may be provided at intervals in the circumferential direction of the outer surface of the main body 22, multiple heat conductive members 21 may be provided at intervals in the circumferential direction of the inner surface of the main body 22, or heat conductive members 21 may be provided at intervals in the circumferential direction of both the outer and inner surfaces of the main body 22. The heat conductive members 21 are provided at intervals from each other to further increase the surface area of ​​the cooling step 20, thereby further improving the heat dissipation effect of the cooling step 20.

[0032] It should be explained that the structural shapes of the heat conductive members 21 provided on the outer surface and inner surface of the main body 22 may be the same or different.

[0033] For example, referring to Figure 6, the heat conductive member 21 includes a first heat conductive member 211 provided on the inner surface of the main body 22, and the first heat conductive member 211 is a rectangular parallelepiped.

[0034] As another example, referring to Figure 5, the first heat conductive member 211 has a first arcuate surface 211a and a second arcuate surface 211b, both curved in a direction toward each other, with one side of the first arcuate surface 211a and the second arcuate surface 211b located on the inner surface of the main body 22, and the other side of the first arcuate surface 211a and the second arcuate surface 211b having a common edge that is away from the main body 22.

[0035] Specifically, the first heat conduction member 211 is an arc-shaped heat conduction member. The first heat conduction member 211 employs an arc-shaped surface that bulges in the center, thereby increasing the surface area of ​​the first heat conduction member 211 and further improving the heat conduction effect. In addition, both sides of the first arc-shaped surface 211a and the second arc-shaped surface 211b are curved in directions toward each other, and the sides of the first arc-shaped surface 211a and the second arc-shaped surface 211b that are away from the main body 22 overlap, i.e., they are common sides, which facilitates energy exchange between the first heat conduction member 211 and the aerosol.

[0036] As yet another example, referring to Figure 7, the first heat conductive member 211 has a first end 2111 provided on the inner surface of the main body 22 and a second end 2112 facing the first end 2111, the width of the second end 2112 gradually decreasing in the direction away from the first end 2111.

[0037] Specifically, one end of the first heat conduction member 211 connected to the inner surface of the main body 22 is the first end 2111, and the other end of the first heat conduction member 211 away from the main body 22 is the second end 2112. The shape of the first end 2111 is not limited and may be a structure of equal width such as a rectangular parallelepiped. The width of the cross-section 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 structure in which the width gradually decreases, which facilitates the flow of aerosols in the airflow passage 20a.

[0038] In one embodiment, referring to Figures 8 and 9, the heat conduction member 21 includes a second heat conduction member 212 provided on the outer surface of the main body 22, and the width of the second heat conduction member 212 gradually decreases in the direction away from the main body 22. Therefore, energy exchange between the second heat conduction member 212 and the external environment can be facilitated.

[0039] In one embodiment, referring to Figures 1, 3, and 4, the aerosol generating product comprises a tubular body 50 having a lumen and an intake port 50a, and a medium stage 10, a cooling stage 20, and a filtration stage 40 are sequentially provided within the lumen, and at least a portion of the main body 22 is provided at a distance from the tubular body 50 to form a gap space 20b, and the gap space 20b communicates with the intake port 50a and the airflow passage 20a, respectively, forming a second airflow path between the intake port 50a and the filtration stage 40, through the gap space 20b and the airflow passage 20a.

[0040] Specifically, the intake port 50a communicates with the lumen. The aerosol-generating product includes two airflow paths. By providing two airflow paths, the intake volume of the aerosol-generating product can be increased, making it easier for the user to inhale.

[0041] The intake holes 50a are air inlets for external airflow to flow along the second airflow path. Their specific installation location and number are not limited. For example, multiple intake holes 50a are provided at intervals on the side wall of the pipe body 50.

[0042] The main body 22 may have a gap between it and the tube 50 throughout its entire area, or it may have a gap between it and the tube 50 in only a portion of its area.

[0043] In practice, the lower end of the aerosol-generating product further has an air inlet for external airflow to flow along the first airflow path.

[0044] In one specific embodiment, a heat conductive member 21 is provided on the outer surface of the main body 22, located within the spacing space 20b.

[0045] In other words, at least a portion of the heat conductive member 21 is provided within the gap space 20b. During suction, after the cooling step 20 exchanges energy with the aerosol, at least a portion of the heat can be transferred to the gap space 20b by the heat conductive member 21 provided within the gap space 20b. Therefore, the external airflow flowing into the second airflow path can be preheated, and the liquid penetration phenomenon caused by cooling and condensation in the medium step 10 and the cooling step 20 can be reduced.

[0046] In one embodiment, the cooling step 20 is integrally injection molded with at least one of graphite and a metallic material and an organic polymer material.

[0047] Specifically, the material of the cooling stage 20 may include graphite, a metallic material, and an organic polymer material, or it may only include graphite and an organic polymer material, or it may only include a metallic material and an organic polymer material.

[0048] Integral injection molding refers to the process of integrally molding an organic polymer material by mixing it with graphite and / or a metal material and then injecting, extruding, or pressing it. Therefore, the thermal conductivity of the cooling stage 20 can be increased, resulting in a good heat dissipation effect.

[0049] Here, the specific type of metallic material may be determined according to the actual situation. For example, the metallic material may include at least one of iron, aluminum, and copper. In other words, the metallic material may include one or more of iron, aluminum, and copper.

[0050] Furthermore, the organic polymer material includes at least one of the following: fibrous paper, silica gel, polylactic acid material (PLA), and polyadipic acid material (PBAT). In other words, the organic polymer material may be one or more of the above materials.

[0051] It should be explained that the structure of the cooling stage 20 itself has micropores, and during suction, a "liquid film" is formed on the inner surface of the main body 22, which can adsorb large aerosol molecules in the airflow passage 20a. As a result, the "graininess" experienced by the user during suction can be reduced, and therefore the user experience can be improved.

[0052] The ratio of the surface area of ​​the heat conductive member 21 to the surface area of ​​the cooling step 20 should be within an appropriate range so as not to impair the heat dissipation effect of the cooling step 20. It is desirable that it not be too small, and also desirable that it not be too large in order to prevent the installation of heat conductive members 21 from becoming too dense and affecting the efficiency of energy exchange between the cooling step 20 and aerosols or the external environment.

[0053] For example, the surface area of ​​the heat conductive member 21 is 40% or more of the surface area of ​​the cooling step 20, and 80% or less of the surface area of ​​the cooling step 20. For example, 40%, 60%, 70%, or 80%.

[0054] In one embodiment, the thermal conductivity of the cooling stage 20 is 2700 W / (m·K) or higher and 5300 W / (m·K) or lower. The cooling stage 20 has high thermal conductivity and therefore can rapidly transfer heat from the aerosol to the external environment. For example, the thermal conductivity of the cooling stage 20 is 2700 W / (m·K) or 5300 W / (m·K).

[0055] In one specific embodiment, the cooling step 20 has multiple heat conductive members 21 provided only on the inner surface of the main body 22, and the surface area of ​​the heat conductive members 21 is 40% or more and 70% or less of the surface area of ​​the cooling step 20. The thermal conductivity of the cooling step 20 is 3200 W / (m·K) or more and 4500 W / (m·K) or less. For example, 3200 W / (m·K), 4000 W / (m·K), or 4500 W / (m·K).

[0056] In one specific embodiment, multiple heat conductive members 21 are provided on the inner and outer surfaces of the main body 22, and the surface area of ​​the heat conductive members 21 is 60% or more and 80% or less of the surface area of ​​the cooling step 20. The thermal conductivity of the cooling step 20 is 3700 W / (m·K) or more and 4700 W / (m·K) or less. For example, 3700 W / (m·K), 4200 W / (m·K), or 4700 W / (m·K).
