The present application provides a cooling component 10 . Please refer to Figure 1 and Figure 2, Figure 1 is a schematic structural diagram of a cooling assembly provided in an embodiment of the present application; Figure 2 is an exploded perspective view of the cooling assembly provided in the embodiment of Figure 1. The cooling assembly 10 includes a cooling tube 11 , a first air-permeable sealing portion 12 and a cooling portion 13 . The cooling tube 11 includes a first end 111 and a second end 112 oppositely disposed, and the cooling tube 11 has a receiving space 113 passing through the first end 111 and the second end 112 . The first air-permeable sealing portion 12 is disposed on the first end 111 and is used to close the first end 111 . The cooling unit 13 is accommodated in the accommodation space 113 .

In this embodiment, the cooling assembly 10 is mainly used in heat-not-burn pods. The heat-not-burn pod will form a high-temperature aerosol after being heated, and the temperature is 200-380°C. The cooling component 10 is used to cool the high-temperature aerosol to a temperature suitable for smoking.

In this embodiment, the cooling tube 11 is a channel for circulating the aerosol, and the high-temperature aerosol flows through the cooling tube 11 , and the temperature of the aerosol is lowered through the cooling of the cooling tube 11 . The cooling pipe 11 is made of food-grade material, which can reduce or even not produce toxic substances when heated. For example, the material of the cooling pipe 11 may be, but not limited to, food grade materials such as white cardboard or kraft paper. Specifically, the cooling pipe 11 can be, but not limited to, white cardboard of 50-200 g/㎡, kraft paper of 50-200 g/㎡, and the like. In order to reduce the temperature of the high-temperature aerosol to a suitable suction temperature for the existing cooling tube 11, it is usually necessary to set the length of the cooling tube 11 longer. The cooling assembly 10 provided by this application, because the cooling part 13 The existence of , can improve the cooling capacity of the cooling assembly 10 , so the length of the cooling tube 11 of the present application can be set shorter than that of the existing cooling tube 11 . Specifically, the range of the length L1 of the cooling tube 11 is: 15mm≦L1≦22mm. In addition, in order to maintain the concentration of the aerosol and the sense of resistance to sucking the aerosol, the diameter D1 of the cooling tube 11 is in the range of: 6mm≦D1≦6.6mm. If the diameter D1 of the cooling tube 11 is too small, the resistance to sucking the aerosol is too large, and if the diameter D1 of the cooling tube 11 is too large, the concentration of the aerosol in the cooling tube 11 will be too high. Small, affecting the taste of the inhaled aerosol. Therefore, the range of the diameter D1 of the cooling tube 11 is: 6mm≦D1≦6.6mm, which can make the aerosol concentration in the cooling tube 11 full while ensuring low suction resistance.

It should be noted that the suction resistance refers to the resistance encountered when the aerosol is sucked into the cooling tube 11 and the aerosol is sucked out of the cooling tube 11 .

In this embodiment, the first air-permeable sealing portion 12 is used to close the first end 111 . When the cooling assembly 10 is set on a heat-not-burn cartridge, the first end 111 is set towards the smoking element, and the second end 112 is set towards the filter element. Therefore, the first air-permeable sealing portion 12 can prevent the cooling portion 13 from falling into the smoking article. The first air-permeable sealing part 12 is made of food-grade material, which can reduce or even eliminate the generation of poison when heated. For example, the material of the first air-permeable sealing part 12 may be, but not limited to, food-grade materials such as silk tissue paper, highly air-permeable paper, or butter paper. Specifically, the first air-permeable sealing part 12 may be, but not limited to, 10-50 g/m2 silk cotton paper, 10-50 g/m2 highly air-permeable paper, or 45-105 g/m2 butter paper. The diameter of the first air-permeable sealing part 12 is consistent with the diameter of the cooling pipe 11 , specifically, the diameter D2 of the first air-permeable sealing part 12 is in the range of: 6mm≦D2≦6.6mm. If the diameter of the first air-permeable sealing portion 12 is smaller than the diameter of the cooling pipe 11 , ie, D2<D1, the first air-permeable sealing portion 12 cannot completely seal the cooling pipe 11 . If the diameter of the first air-permeable sealing part 12 is larger than the diameter of the cooling pipe 11, that is, D2>D1, the first air-permeable sealing part 12 will partially protrude from the cooling pipe 11 in the circumferential direction, so that It affects the subsequent preparation and assembly of the cooling component 10 . Therefore, the diameter of the first air-permeable sealing part 12 is consistent with the diameter of the cooling tube 11, so that the first air-permeable sealing part 12 can completely seal the first end 111 without affecting the cooling assembly 10. Subsequent preparation and assembly. The first air-permeable sealing portion 12 may be, but not limited to, bonded to the first end 111 by food-grade materials such as edible glue.

Specifically, the cooling part 13 is a food-grade cooling material, which can reduce or even eliminate the generation of toxic substances when heated. In this embodiment, the cooling portion 13 can be in any shape. For example, the cooling portion 13 can be in the shape of granules, strips, or blocks, as long as the cooling portion 13 can be filled to In the cooling pipe 11, it is sufficient to play the role of cooling.

The cooling tube 11 has a The receiving space 113 of the first end 111 and the second end 112, the first air-permeable sealing part 12 is arranged on the first end 111, and is used to close the first end 111, and the cooling part 13 accommodates in the receiving space 113 . When the cooling assembly 10 is used in heat-not-burn pods, the high-temperature aerosol will enter the storage space 113 of the cooling tube 11 through the first end 111, flow through the cooling part 13, and flow from the first end 111. The two ends 112 flow out, and the cooling part 13 will be near the first end 111 due to its own weight. When the high-temperature aerosol circulates in the cooling tube 11, because the cooling part 13 can quickly absorb the The heat causes the temperature of the aerosol to drop rapidly. In addition, the cooling tube 11 has a certain length, and the heat of the aerosol will be dissipated into the air in the cooling tube 11 during the circulation process, and transferred to the outside of the cooling tube 11 through the cooling tube 11, Thereby the temperature of the aerosol is further reduced. Therefore, the cooling assembly 10 provided in the present application can quickly cool down the high-temperature aerosol.

When the cooling assembly 10 is set on a heat-not-burn cartridge, the first end 111 is set towards the smoking element, and the second end 112 is set towards the filter element. Therefore, the first air-permeable sealing portion 12 can prevent the cooling portion 13 from falling into the filter element. The second gas-permeable sealing part 14 is made of food-grade material, which can reduce or even eliminate the generation of poison when heated. For example, the material of the second air-permeable sealing part 14 may be, but not limited to, food-grade materials such as silk tissue paper, highly air-permeable paper, or butter paper. Specifically, the cooling pipe 11 can be, but not limited to, 10-50 g/㎡ silk cotton paper, 10-50 g/㎡ high air permeability paper or 45-105 g/㎡ butter paper, etc. The diameter of the second air-permeable sealing part 14 is consistent with the diameter of the cooling pipe 11 , specifically, the diameter D3 of the second air-permeable sealing part 14 is in the range of: 6mm≦D3≦6.6mm. If the diameter of the second air-permeable sealing portion 14 is smaller than the diameter of the cooling pipe 11 , ie, D3<D1, the second air-permeable sealing portion 14 cannot completely seal the cooling pipe 11 . If the diameter of the second air-permeable sealing part 14 is larger than the diameter of the cooling pipe 11, that is, D3>D1, the second air-permeable sealing part 14 will partially protrude from the cooling pipe 11 in the circumferential direction, so that It affects the subsequent preparation and assembly of the cooling component 10 . Therefore, the diameter of the second air-permeable sealing part 14 is consistent with the diameter of the cooling pipe 11, so that the second air-permeable sealing part 14 can completely seal the second end 112 without affecting the cooling assembly 10. Subsequent preparation and assembly. The second gas-permeable sealing portion 14 may be, but not limited to, bonded to the second end 112 by food-grade materials such as edible glue.
