[0044] See also Figure 1 、 Figure 2 and Figure 3 , Figure 1 1 is a schematic structural diagram of the electronic atomization device provided by the present invention; Figure 2 1 is a schematic structural diagram of an atomizer in the electronic atomization device provided by the present invention; Figure 3 For Figure 2Schematic diagram of the enlarged three-dimensional structure at point A in the figure. The electronic atomization device 100 provided in this embodiment includes an atomizer 10 and a host 20. The atomizer 10 and the host 20 are detachably connected. Among them, the atomizer 10 specifically includes a liquid storage tank 4, a mounting seat 1 and an atomizing core 2. A power supply component is provided in the host 20, and the atomizer 10 is plugged into one end port of the host 20 and connected to the power supply component in the host 20 to supply power to the atomizing core 2 in the atomizer 10 through the power supply component. When the atomizer 10 needs to be replaced, the atomizer 10 can be disassembled and a new atomizer 10 can be installed on the host 20 to achieve the reuse of the host 20.

[0045] In another optional embodiment, the provided electronic atomization device 100 includes a liquid storage tank 4, a mounting base 1, an atomizer core 2, and a power supply assembly. The liquid storage tank 4, the mounting base 1, the atomizer core 2, and the power supply assembly are integrally arranged and cannot be detachably connected.

[0046] Of course, the electronic atomization device 100 also includes other components in the existing electronic atomization device 100, such as a microphone, a bracket, etc. The specific structures and functions of these components are the same or similar to those in the prior art. Please refer to the prior art for details and will not be repeated here.

[0047] The atomizer 10 provided in the above embodiment includes a liquid storage tank 4, a mounting base 1 and an atomizer core 2. The liquid storage tank 4 is used to store liquid; in this embodiment, the liquid is e-liquid. The mounting base 1 includes a leakage buffer structure 122 with capillary force. The atomizer core 2 includes a porous matrix 21 and a heating element 22; the porous matrix 21 is in fluid communication with the liquid storage tank 4 and absorbs the liquid from the liquid storage tank 4 through capillary force, and the heating element 22 heats the liquid in the atomized porous matrix 21. The atomizer core 2 is located between the liquid storage tank 4 and the leakage buffer structure 122; the leakage buffer structure 122 abuts against the porous matrix 21 and is used to receive and store liquid overflowing from the porous matrix 21.

[0048] The atomizer 10 further includes a seal 3, which is disposed between the mounting base 1 and the atomizing core 2. The seal 3 may be a sealing ring. The porous substrate 21 may be any one of porous ceramics and porous metals.

[0049] The porous matrix 21 communicates with the liquid stored in the liquid reservoir 4 and absorbs the liquid from the reservoir 4 through capillary action. The heating element 22 is used to heat the liquid in the atomized porous matrix 21. In one embodiment, the porous matrix 21 includes an oil transfer portion 211 and a raised portion 212 integrally formed on one side of the oil transfer portion 211. The leakage buffer structure 122 is in contact with the periphery of the surface of the oil transfer portion 211 on which the raised portion 212 is located. The surface of the raised portion 212 facing away from the oil transfer portion 211 is the atomizing surface 214, while the surface of the oil transfer portion 211 in contact with the e-liquid is the liquid absorbing surface 213. The leakage buffer structure 122 is in contact with the edge of the surface of the oil transfer portion 211 on which the raised portion 212 is located. That is, the leakage buffer structure 122 is arranged in contact with the edge of the oil transfer portion 211 and spaced apart from the raised portion 212. This prevents the leakage buffer structure 122 from being damaged by the high temperature of the heating element 22 on the atomizing surface 214. The atomizing surface 214 is provided with a heating element 22. Specifically, the heating element 22 can be a heating film or a heating circuit. In one embodiment, the heating element 22 is electrically connected to an electrode, one end of which extends through the base 121 and is connected to the power supply assembly. Specifically, the oil transfer portion 211 and the raised portion 212 are integrally formed, and both the oil transfer portion 211 and the raised portion 212 are made of porous materials. For example, the material of the oil transfer portion 211 and the raised portion 212 can be porous ceramic or porous metal, but is not limited to these two materials, as long as they can transfer the e-liquid in the liquid reservoir 4 to the heating element 22 for atomization through capillary action. The oil transfer portion 211 only partially covers the leakage buffer structure 122. The capillary force of the porous matrix 21 is greater than that of the leakage buffer structure 122. When the heating element 22 heats the liquid in the atomized porous matrix 21, the liquid received by the leakage buffer structure 122 can flow back into the porous matrix 21 and be heated and atomized.

[0050] The mounting base 1 has an atomizing chamber 125, in which the atomizing core 2 is housed. The liquid leakage buffer structure 122 is connected to the bottom of the atomizing chamber 125 and absorbs the accumulated liquid at the bottom of the atomizing chamber 125 through capillary force. The mounting base 1 includes an upper body 11 and a lower body 12. The lower body 12 includes a base 121. The upper body 11 is provided with a lower liquid hole 111. The liquid in the liquid storage tank 4 flows to the porous base 21 through the lower liquid hole 111. The liquid leakage buffer structure 122 is provided on the lower body 12. The porous base 21 includes a liquid absorption surface 213 and an atomizing surface 214. The liquid absorption surface 213 is connected to the lower liquid hole 111. The heating element 22 is provided on the atomizing surface 214. The porous base 21 is in contact with the liquid leakage buffer structure 122.

[0051] Among them, when the pressure of the liquid storage tank 4 increases, the pressure of the liquid storage tank 4 is greater than the pressure of the atomization chamber 125, and the pressure difference between the liquid storage tank 4 and the atomization chamber 125 squeezes the liquid in the liquid storage tank 4 to the porous matrix 21, causing excess liquid to overflow from the porous matrix 21, and the leakage buffer structure 122 receives and locks the overflowing excess liquid; when the pressure of the liquid storage tank 4 decreases, the pressure of the liquid storage tank 4 is less than the pressure of the atomization chamber 125, and the pressure difference between the liquid storage tank 4 and the atomization chamber 125 causes the liquid in the leakage buffer structure 122 to flow back to the porous matrix 21 in contact with it through capillary action, and the porous matrix 21 returns the liquid therein to the liquid storage tank 4.

[0052] In this embodiment, the upper body 11 and the lower body 12 are made as one piece, and a slot 112 can also be provided on the upper body 11. A clip 124 is provided on the outer wall of the lower body 12 for engaging with the slot 112 on the upper body 11 to fix the lower body 12 to the upper body 11.

[0053] The material of the leakage buffer structure 122 is a porous material, which can be a hard porous material or a soft porous material.

[0054] When the leakage buffer structure 122 is made of a hard porous material, in order to save space, the leakage buffer structure 122 can also be used to support the atomizer core 2. The hard porous material can be at least one of porous ceramics and porous metals, or other materials with supporting and liquid absorbing capabilities.

[0055] See also Figure 4 , Figure 4 This is a schematic diagram of the first embodiment of the leakage buffer structure provided by the present invention. In one specific embodiment, the leakage buffer structure 122 includes two spaced-apart sub-leakage buffers 1221. The sub-leakage buffers 1221 are made of a hard porous material, such as porous ceramic or porous metal, that has both support and liquid absorption capabilities. Therefore, they can serve as supports for the atomizer core 2. It is understood that if the atomizer core 2 is secured by other components, the sub-leakage buffers 1221 may not be used to support the atomizer core 2. When the pressure in the liquid reservoir 4 is greater than the pressure in the atomizer chamber 125, the sub-leakage buffers 1221 can collect liquid leaking from the porous matrix 21. When the pressure in the liquid reservoir 4 is less than the pressure in the atomizer chamber 125, the liquid stored in the sub-leakage buffers 1221 can flow back to the porous matrix 21 in contact with them, thereby effectively utilizing the leaked liquid and enabling the leakage buffer structure 122 to collect and recirculate liquid multiple times. The liquid absorption capacity of the porous material used to form the liquid leakage buffer structure 122 is smaller than that of the porous material used to form the oil transfer portion 211 .

[0056] See also Figure 5 , Figure 5A schematic structural diagram of the second embodiment of the leakage buffer structure provided by the present invention. In another specific embodiment, the leakage buffer structure 122 is U-shaped and the material is a hard porous material. Specifically, the leakage buffer structure 122 includes a sub-leakage buffer 1221 and a connecting portion 1222 connecting the sub-leakage buffer 1221 away from the end of the porous matrix 21. The material of the sub-leakage buffer 1221 and the connecting portion 1222 is a porous material, for example, it can be a material with supporting and liquid absorption capabilities such as porous ceramics and porous metals. The connecting portion 1222 is provided with a channel that matches the air inlet 126 provided on the base 121. The connecting portion 1222 is used to absorb the condensed smoke oil after the atomized smoke oil is condensed in the atomizing chamber 125 formed by the leakage buffer structure 122 and the atomizing core 2, to prevent the condensed smoke oil from leaking through the air inlet 126.

[0057] See also Figure 6 , Figure 6This is a schematic structural diagram of the third embodiment of the liquid leakage buffer structure provided by the present invention. A main body 123 is provided on the lower base 12, and the main body 123 includes a first sub-body 1231 and a second sub-body 1232. The first sub-body 1231 and the second sub-body 1232 are spaced apart and symmetrically arranged. The first sub-body 1231 and the second sub-body 1232 can be arranged parallel and perpendicular to the base 121. In another optional embodiment, the first sub-body 1231 and the second sub-body 1232 can be tilted and symmetrically arranged on the base 121, and the distance between the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121 is greater than the distance between the ends of the first sub-body 1231 and the second sub-body 1232 connected to the base 121. The material of the first sub-body 1231 and the second sub-body 1232 is dense ceramic, dense metal or glass material, or other materials with support capacity but no liquid absorption capacity. In another specific embodiment, the leakage buffer structure 122 is disposed at the ends of the first and second sub-bodies 1231, 1232, distal from the base 121. The ends of the first and second sub-bodies 1231, 1232, distal from the base 121, are connected to the oil transfer unit 211 via the leakage buffer structure 122. The leakage buffer structure 122 can be made of a porous material with both support and absorbency. For example, the material of the leakage buffer structure 122 can be porous ceramic, porous metal, or other materials with both support and absorbency. The leakage buffer structure 122 can collect liquid leaked from the oil transfer unit 211 within the leakage buffer structure 122, or it can return stored liquid within the leakage buffer structure 122 to the oil transfer unit 211 in contact with the leakage buffer structure 122, thereby effectively utilizing the stored liquid and enabling multiple cycles of collection and return of the liquid. The leakage buffer structure 122 can also be made of materials with absorbency but no support, such as cotton, fiber, or absorbent resin. The liquid absorption capacity of the porous material used to form the liquid leakage buffer structure 122 is smaller than that of the porous material used to form the oil transfer portion 211 .

[0058] The leakage buffer structure 122 is made of a soft porous material. The leakage buffer structure 122 is supported by a support portion, with one end of the leakage buffer structure 122 in contact with the porous base 21 and the other end extending to the bottom of the atomization chamber 125. The soft porous material is at least one of cotton, fiber, and resin, and may also be other materials that have liquid absorption capabilities but no support capabilities.

[0059] See also Figure 7 and Figure 8 , Figure 7 A schematic structural diagram of a fourth embodiment of the liquid leakage buffer structure provided by the present invention; Figure 8 yes Figure 7A top view of the leakage buffer structure is provided. In a specific embodiment, the material of the leakage buffer structure 122 is a soft porous material. The anti-leakage liquid absorbing member 1227 is supported by the support portion 127, so that one end of the leakage buffer structure 122 contacts the porous matrix 21, and the other end extends to the bottom of the atomization chamber 125. The support portion 127 includes a first sub-support member 1271 and a second sub-support member 1272. A guide channel 1233 is provided on the first sub-support member 1271 and the second sub-support member 1272, and the leakage buffer structure 122 is provided in the guide channel 1233. One end of the leakage buffer structure 122 contacts the oil transfer portion 211 in the porous matrix 21, and the other end extends to the base 121 of the lower seat 12. The guide channel 1233 can be a groove structure, and the groove size of the guide channel 1233 is larger than the size of the first capillary groove 1223. One end of the diversion channel 1233 is opened on the inner sidewall of the first and second sub-support members 1271 and 1272, and the other end is opened on the end surfaces of the first and second sub-support members 1271 and 1272 away from the base 121. The leakage buffer structure 122 filled in the diversion channel 1233 contacts the oil transfer portion 211. The cross-sectional dimensions of the grooves provided on the surfaces of the first and second sub-support members 1271 and 1272 away from the base 121 are no less than the contact dimension between the oil transfer portion 211 and the first and second sub-support members 1271 and 1272. Specifically, the opening width of the flow channel 1233 at the end surfaces of the first and second sub-support members 1271 and 1272, in the direction of the line connecting the first and second sub-support members 1271 and 1272, is no less than the contact width between the first and second sub-support members 1271 and 1272 and the oil transfer unit 211 in the direction of the line connecting the first and second sub-support members 1271 and 1272. A leakage buffer structure 122 is disposed within the flow channel 1233 and extends from the end of the flow channel 1233. One end of the leakage buffer structure 122 is connected to the oil transfer unit 211, and the other end extends between the first and second sub-support members 1271 and 1272, or alternatively, to the surface of the base 121. This structure collects condensed atomized liquid and prevents it from leaking out of the air inlet 126 provided on the base 121 after cooling and liquefaction, thereby affecting the user experience. When the pressure in the liquid storage tank 4 decreases, the leakage buffer structure 122 can also return the collected smoke liquid to the oil transfer unit 211 through capillary action, thereby effectively utilizing the leaked liquid and enabling the leakage buffer structure 122 to collect and return smoke liquid multiple times. The liquid absorption capacity of the leakage buffer structure 122 is less than that of the oil transfer unit 211. Specifically, the porous material comprising the leakage buffer structure 122 has a smaller absorption capacity than that of the porous material comprising the oil transfer unit 211. The leakage buffer structure 122 can be made of absorbent materials such as cotton, fiber, and absorbent resin.

[0060] When the temperature rises, the volume of bubbles in the liquid in the liquid storage tank 4 expands, increasing the pressure in the liquid storage tank 4, which in turn causes the liquid in the atomizer core 2 to leak out from the end of the oil transfer portion 211 of the atomizer core 2. The leaked liquid from the oil transfer portion 211 can flow to the leakage buffer structure 122 connected to the oil transfer portion 211. The leakage buffer structure 122 is used to collect the leaked liquid. The liquid can penetrate along the extension direction of the leakage buffer structure 122, preventing the liquid from leaking out of the air inlet 126. When the temperature drops, the atomized liquid in the atomization chamber 125 cools and forms liquid, which flows onto the base 121 and is collected by the leakage buffer structure 122 extending to the surface of the base 121. At the same time, the volume of the bubbles in the liquid storage tank 4 will shrink, which will reduce the pressure of the liquid storage tank 4. Furthermore, due to the pressure difference between the inside and outside of the liquid storage tank 4, the liquid collected and stored in the leakage buffer structure 122 will flow to the oil transfer part 211 connected to the leakage buffer structure 122 through capillary action along the leakage buffer structure 122 in the direction close to the oil transfer part 211, thereby realizing the effective utilization of the collected liquid.

[0061] See also Figure 9 , Figure 9 Schematic diagram of the structure of the fifth embodiment of the leakage buffer structure provided by the present invention. In a specific embodiment, the leakage buffer structure 122 includes a body 123 and a first capillary groove 1223 provided on the body 123. The first capillary groove 1223 can be provided on any side surface of the body 123, and the opening can be facing any direction, as long as it can absorb and store leakage. Preferably, the opening of the first capillary groove 1223 faces the atomizing chamber 125. The body 123 is provided on the surface of the base 121 close to the upper body 11 and is fixedly connected to the base 121. The body 123 can be arranged perpendicular to the surface of the base 121 and integrally formed. One end of the body 123 away from the base 121 contacts the oil transfer portion 211, so that the first capillary groove 1223 extends on the body 123 in a direction away from the bottom of the atomizing chamber 125 or the base 121 and contacts the oil transfer portion 211, and the other end extends in a direction close to the bottom of the atomizing chamber 125 or the base 121. The first capillary groove 1223 is used to store liquid leaked from the oil transfer portion 211 and return the leaked liquid to the liquid storage tank 4, thereby preventing liquid leakage and effectively utilizing the stored leaked liquid.

[0062] Among them, a plurality of first capillary grooves 1223 are provided on the side wall surfaces of the first sub-body 1231 and the second sub-body 1232 close to the atomization chamber 125. The plurality of first capillary grooves 1223 arranged side by side form a liquid leakage buffer structure 122. Specifically, the cross-section of the first capillary groove 1223 can be U-shaped, or V-shaped, semi-circular, semi-elliptical, or C-shaped. The shape of its cross-section is not limited here, as long as it is a shape that facilitates drainage and collection. In an optional embodiment, the size of the first capillary groove 1223 is not less than the contact size between the first capillary groove 1223 and the atomization core 2. Here, the size is the width in the direction of the first sub-body 1231 and the second sub-body 1232.

[0063] The bottom of the atomization chamber 125 is the surface of the base 121 connected to the liquid leakage buffer structure 122. A second capillary groove 1224 is provided on the surface of the base 121 connected to the liquid leakage buffer structure 122. The second capillary groove 1224 is provided on the surface of the base 121 between the first sub-body 1231 and the second sub-body 1232 and is connected to the first capillary groove 1223. The first capillary groove 1223 and the second capillary groove 1224 form a capillary groove in an L-shaped structure. Specifically, the cross-sectional shape of the second capillary groove 1224 can be the same as or different from the cross-sectional shape of the structure of the first capillary groove 1223. The number of the second capillary grooves 1224 can be one, that is, one second capillary groove 1224 is connected to all the first capillary grooves 1223 on the first sub-body 1231 or the second sub-body 1232. The number of the second capillary grooves 1224 can be the same as the number of the first capillary grooves 1223, that is, one first capillary groove 1223 is connected to a corresponding second capillary groove 1224. The first capillary groove 1223 can make the e-liquid leaked from the end of the oil transfer part 211 flow to the second capillary groove 1224 along the extending direction of the first capillary groove 1223, store the leaked e-liquid, and prevent the e-liquid from leaking out through the air inlet hole 126 provided on the base 121. Among them, the second capillary groove 1224 can also collect the condensate after the atomized e-liquid is cooled, and prevent the atomized e-liquid from leaking out through the air inlet hole 126 provided on the base 121 after cooling and liquefying, which affects the user experience. The first capillary groove 1223 can also reflux the collected e-liquid to the oil transfer part 211 in contact with it through capillary action, thereby realizing the effective utilization of the collected leaked liquid. Among them, the liquid absorption capacity of the first capillary groove 1223 and the second capillary groove 1224 is less than the liquid absorption capacity of the oil transfer part 211. Specifically, the liquid absorption capacity of the first capillary groove 1223 and the second capillary groove 1224 is less than the liquid absorption capacity of the porous material used to make the oil transfer part 211.

[0064] In another specific embodiment, the leakage buffer structure 122 also supports the atomizer coil 2. Specifically, to save space, the first sub-body 1231 and the second sub-body 1232, each provided with the first capillary groove 1223, also support the atomizer coil 2. The ends of the first and second sub-bodies 1231, 1232 facing away from the base 121 support the atomizer coil 2. The oil transfer portion 211 covers the ends of the first and second sub-bodies 1231, 1232 facing away from the base 121. A raised portion 212 provided on one side of the oil transfer portion 211 is disposed between the first and second sub-bodies 1231, 1232.

[0065] See 10, Figure 10 This is a schematic diagram of the phenomenon of the atomizer provided by the present invention during the heating process. As the temperature rises, the volume of the bubbles in the smoke oil in the liquid storage tank 4 will expand, increasing the pressure in the liquid storage tank 4, and thus causing the smoke oil in the atomizer core 2 to leak out from the end of the oil transfer portion 211 in the atomizer core 2. The smoke oil leaking from the end of the oil transfer portion 211 can flow to the first capillary groove 1223 connected to the oil transfer portion 211, and the leaked smoke oil is collected by the first capillary groove 1223. The smoke oil can flow along the first capillary groove 1223 provided on the first sub-body 1231 and the second sub-body 1232 to the second capillary groove 1224, and the leaked smoke oil is collected by the first capillary groove 1223 and the second capillary groove 1224, thereby preventing the leaked smoke oil from leaking out of the air inlet 126. Please refer to 11, Figure 11 This is a schematic diagram of the phenomenon occurring during the cooling process of the atomizer provided by the present invention. As the temperature decreases, the atomized tobacco liquid in the atomization chamber 125, which is composed of the first sub-body 1231, the second sub-body 1232, the base 121, and the atomizer core 2, cools to form tobacco liquid, which then flows onto the base 121 and is collected by the second capillary groove 1224. Simultaneously, the volume of bubbles in the tobacco liquid in the liquid reservoir 4 decreases, reducing the pressure in the reservoir 4. Consequently, due to the pressure differential between the inside and outside of the reservoir 4, the tobacco liquid collected and stored in the first capillary groove 1223 and the second capillary groove 1224 flows through capillary action along the first capillary groove 1223, away from the second capillary groove 1224, to the oil transfer portion 211 connected to the first capillary groove 1223. Because the liquid absorption capacity of the oil transfer portion 211 is greater than that of the first and second capillary grooves 1223 and 1224, the oil transfer portion 211 can absorb the tobacco liquid and effectively utilize the collected tobacco liquid.

[0066] See also Figure 12 , Figure 12Schematic diagram of the sixth embodiment of the liquid leakage buffer structure provided by the present invention. The liquid leakage buffer structure 122 includes a main body 123 and capillary pores 1225 provided on the main body 123. A plurality of capillary pores 1225 are provided on the first sub-body 1231 and the second sub-body 1232. One end of the capillary pore 1225 extends on the main body 123 in a direction away from the bottom of the atomization chamber 125 and contacts the porous matrix 21, and the other end extends in a direction close to the bottom of the atomization chamber 125. Specifically, the cross-sectional shape of the capillary pore 1225 structure can be rectangular, or triangular, circular, semi-circular, elliptical, and its cross-sectional shape is not limited herein, as long as it is a shape convenient for drainage and collection. In an optional embodiment, the distribution width of the capillary pores 1225 on the end faces of the first sub-body 1231 and the second sub-body 1232 contacting the porous matrix 21 is not less than the contact width between the first sub-body 1231 and the second sub-body 1232 and the porous matrix 21. This width is in the connection direction of the first sub-body 1231 and the second sub-body 1232. The surface of the base 121 connected to the main body 123 is provided with a second capillary groove 1224. The second capillary groove 1224 is provided on the surface of the base 121 between the first sub-body 1231 and the second sub-body 1232 and is connected to the capillary pore 1225 structure. Specifically, the cross-sectional shape of the second capillary groove 1224 can be U-shaped, or V-shaped, semi-circular, elliptical, C-shaped, and its cross-sectional shape is not limited herein, as long as it is a shape convenient for collection. The number of capillary pores 1225 can be one, that is, one second capillary groove 1224 is connected to all the capillary pores 1225 on the first sub-body 1231 or the second sub-body 1232. The number of the second capillary grooves 1224 can be the same as the number of the capillary pores 1225, that is, one capillary pore 1225 is connected to a corresponding second capillary groove 1224. The leaked e-liquid can flow along the capillary pores 1225 to the second capillary groove 1224 to store the leaked e-liquid and prevent the e-liquid from leaking out through the air inlet hole 126 provided on the base 121. Among them, the second capillary groove 1224 can also collect the condensate after the atomized e-liquid is cooled, and prevent the atomized e-liquid from leaking out through the air inlet hole 126 provided on the base 121 and affecting the user experience. The capillary pores 1225 can also reflux the collected e-liquid to the oil transmission part 211 in contact with it through capillary action, thereby realizing the effective utilization of the collected liquid leakage and prolonging the service time of the second capillary groove 1224. Among them, the liquid absorption capacity of the capillary pores 1225 and the second capillary groove 1224 is less than the liquid absorption capacity of the oil transmission part 211. Specifically, the liquid absorption capacity of the capillary pores 1225 and the second capillary groove 1224 is less than the liquid absorption capacity of the porous material made of the oil transmission part 211.

[0067] When the temperature rises, the bubbles in the liquid reservoir 4 expand, increasing the pressure in the reservoir 4 and causing the liquid in the atomizer core 2 to leak out from the end of the oil transfer portion 211 of the atomizer core 2. The leaked liquid can flow to the capillary pores 1225 connected to the oil transfer portion 211, where it is collected by the capillary pores 1225. The liquid can then flow along the capillary pores 1225 provided on the first and second sub-bodies 1231 and 1232 to the second capillary grooves 1224, where it is collected and prevented from leaking out of the air inlet 126. When the temperature drops, the atomized liquid in the atomizer chamber 125 cools and forms liquid, which then flows to the base 121 and is collected by the second capillary grooves 1224. At the same time, the volume of the bubbles in the smoke oil in the liquid storage tank 4 will shrink, causing the pressure in the liquid storage tank 4 to decrease. As a result, due to the pressure difference between the inside and outside of the liquid storage tank 4, the smoke oil collected and stored in the capillary pores 1225 and the second capillary grooves 1224 will flow through capillary action along the capillary pores 1225 away from the second capillary grooves 1224 to the oil transfer part 211 connected to the capillary pores 1225. Since the liquid absorption capacity of the oil transfer part 211 is greater than the liquid absorption capacity of the capillary pores 1225 and the second capillary grooves 1224, the oil transfer part 211 can absorb the smoke oil and realize the effective utilization of the collected smoke oil.

[0068] In another optional embodiment, the leakage buffer structure 122 includes a first capillary groove 1223 and a soft porous material, the soft porous material is filled in the first capillary groove 1223, and the liquid absorption capacity of the first capillary groove 1223 and the soft porous material is less than the liquid absorption capacity of the porous matrix 21.

[0069] In another optional embodiment, the leakage buffer structure 122 includes capillaries 1225 and a soft porous material. The capillaries 1225 are filled with the soft porous material. The liquid absorption capacity of the capillaries 1225 and the soft porous material is smaller than the liquid absorption capacity of the porous matrix 21.
