[0003] This invention relates to the field of atomization device technology, and in particular to an atomizer and its electronic atomization device. Background Technology

[0004] An atomizer is a device that atomizes e-liquid or other liquids, and it is widely used in electronic atomization devices and medical fields. In existing technologies, after storing e-liquid in an electronic atomizer, air bubbles are generated in the reservoir due to temperature changes in the cartridge. The thermal expansion and contraction of these bubbles can cause the e-liquid to be squeezed out of the reservoir and leak from the air intake at the bottom of the atomizer, affecting the overall atomization experience.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the electronic atomization device provided by the present invention; Figure 2 This is a schematic diagram of the atomizer in the electronic atomization device provided by the present invention; Figure 3 For is Figure 2 The enlarged three-dimensional structural diagram at point A is shown. The electronic atomizing device 100 provided in this embodiment includes an atomizer 10 and a main unit 20. The atomizer 10 and the main unit 20 are detachably connected. Specifically, the atomizer 10 includes a liquid reservoir 4, a mounting base 1, and an atomizing coil 2. A power supply component is provided inside the main unit 20. The atomizer 10 is plugged into one end port of the main unit 20 and connected to the power supply component inside the main unit 20 to supply power to the atomizing coil 2 in the atomizer 10. When the atomizer 10 needs to be replaced, it can be disassembled and a new atomizer 10 can be installed on the main unit 20, enabling the main unit 20 to be reused.

[0047] In another optional embodiment, the provided electronic atomizing device 100 includes a liquid storage tank 4, a mounting base 1, an atomizing core 2, and a power supply assembly. The liquid storage tank 4, mounting base 1, atomizing core 2, and power supply assembly are integrally formed and cannot be detached.

[0048] Of course, the electronic atomizing device 100 also includes other components found in existing electronic atomizing devices 100, such as microphones and brackets. The specific structure and function of these components are the same as or similar to those in the prior art, and can be found in the prior art for details, which will not be repeated here.

[0049] The atomizer 10 provided in the above embodiment includes a liquid storage chamber 4, a mounting base 1, and an atomizing core 2. The liquid storage chamber 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 action. The atomizing core 2 includes a porous substrate 21 and a heating element 22; the porous substrate 21 is in fluid communication with the liquid storage chamber 4 and adsorbs liquid from the liquid storage chamber 4 through capillary action, while the heating element 22 heats and atomizes the liquid in the porous substrate 21. The atomizing core 2 is located between the liquid storage chamber 4 and the leakage buffer structure 122; the leakage buffer structure 122 abuts against the porous substrate 21 and is used to receive and store liquid overflowing from the porous substrate 21.

[0050] The atomizer 10 also includes a seal 3, which is disposed between the mounting base 1 and the atomizing core 2. The seal 3 can be a sealing ring. The porous substrate 21 can be any one of porous ceramic or porous metal.

[0051] The porous substrate 21 is in communication with the liquid stored in the liquid storage tank 4 and adsorbs the liquid from the liquid storage tank 4 through capillary action. The heating element 22 is used to heat and atomize the liquid in the porous substrate 21. In one embodiment, the porous substrate 21 includes an oil transfer portion 211 and a protrusion 212 integrally formed on one side of the oil transfer portion 211. The leakage buffer structure 122 contacts the periphery of the side surface of the oil transfer portion 211 where the protrusion 212 is located. The surface of the protrusion 212 away from the oil transfer portion 211 is the atomizing surface 214, and the surfaces of the oil transfer portion 211 that are in contact with the e-liquid are all liquid absorption surfaces 213. The leakage buffer structure 122 contacts the edge of the side surface of the oil transfer portion 211 where the protrusion 212 is located. That is, the leakage buffer structure 122 is arranged to contact the edge of the oil transfer portion 211 and is spaced apart from the protrusion 212. This can prevent the high temperature of the heating element 22 on the atomizing surface 214 from damaging the leakage buffer structure 122. 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 a specific embodiment, the heating element 22 is electrically connected to an electrode, and one end of the electrode extends out of the base 121 and is connected to a power supply assembly. Specifically, the oil transfer part 211 and the protrusion 212 are integrally formed, and both the oil transfer part 211 and the protrusion 212 are made of porous materials. For example, the materials of the oil transfer part 211 and the protrusion 212 can be porous ceramics or porous metals, but are not limited to these two materials, as long as they can transfer the e-liquid in the liquid storage tank 4 to the heating element 22 for atomization through capillary action. The oil transfer part 211 only covers part of the leakage buffer structure 122. The capillary force of the porous substrate 21 is greater than that of the leakage buffer structure 122. When the heating element 22 heats and atomizes the liquid in the porous substrate 21, the liquid received by the leakage buffer structure 122 can flow back to the porous substrate 21 and be heated and atomized.

[0052] Mounting base 1 has an atomizing chamber 125, in which the atomizing core 2 is housed. A leakage buffer structure 122 is connected to the bottom of the atomizing chamber 125 and adsorbs the accumulated liquid at the bottom of the atomizing chamber 125 through capillary action. 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 has a liquid outlet 111 through which the liquid in the storage tank 4 flows to the porous substrate 21. The lower body 12 is provided with a leakage buffer structure 122. The porous substrate 21 includes a liquid absorption surface 213 and an atomizing surface 214. The liquid absorption surface 213 is connected to the liquid outlet 111. The heating element 22 is disposed on the atomizing surface 214. The porous substrate 21 is in contact with the leakage buffer structure 122.

[0053] When the pressure in the liquid storage chamber 4 increases, and the pressure in the liquid storage chamber 4 is greater than the pressure in the atomizing chamber 125, the pressure difference between the liquid storage chamber 4 and the atomizing chamber 125 squeezes the liquid in the liquid storage chamber 4 to the porous substrate 21, causing the porous substrate 21 to overflow with excess liquid. The leakage buffer structure 122 receives and locks in the overflowing excess liquid. When the pressure in the liquid storage chamber 4 decreases, and the pressure in the liquid storage chamber 4 is less than the pressure in the atomizing chamber 125, the pressure difference between the liquid storage chamber 4 and the atomizing chamber 125 causes the liquid in the leakage buffer structure 122 to flow back to the porous substrate 21 in contact with it through capillary action. The porous substrate 21 then returns the liquid in it to the liquid storage chamber 4.

[0054] In this embodiment, the upper seat 11 and the lower seat 12 are integrally formed. Alternatively, a slot 112 can be provided on the upper seat 11, and a clip 124 can be provided on the outer side wall of the lower seat 12 for engaging with the slot 112 on the upper seat 11, so that the lower seat 12 is fixedly connected to the upper seat 11.

[0055] The material of the leakage buffer structure 122 is a porous material, which can be a rigid porous material or a soft porous material.

[0056] The material of the leakage buffer structure 122 is a rigid porous material. To save space, the leakage buffer structure 122 can also be used to support the atomizing core 2. The rigid porous material is at least one of porous ceramics and porous metals, or other materials with supporting and liquid-absorbing capabilities.

[0057] Please see Figure 4 , Figure 4 This is a schematic diagram of the first embodiment of the leakage buffer structure provided by the present invention. In a 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 ceramics or porous metals, which have supporting and liquid-absorbing capabilities, and can therefore be used as supports for the atomizing core 2. It is understood that if the atomizing core 2 is fixed by other components, the sub-leakage buffers 1221 may not be used to support the atomizing core 2. When the pressure in the liquid storage chamber 4 is greater than the pressure in the atomizing chamber 125, the sub-leakage buffers 1221 can collect the e-liquid leaking from the porous substrate 21; when the pressure in the liquid storage chamber 4 is less than the pressure in the atomizing chamber 125, the e-liquid stored in the sub-leakage buffers 1221 can flow back to the porous substrate 21 in contact with it, thereby achieving effective utilization of the leaked e-liquid and enabling the leakage buffer structure 122 to achieve multiple cycles of collecting and returning e-liquid. The liquid absorption capacity of the porous material used to make the leakage buffer structure 122 is less than that of the porous material used to make the oil transfer part 211.

[0058] Please see Figure 5 , Figure 5This is a schematic 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 made of a rigid porous material. Specifically, the leakage buffer structure 122 includes a sub-leakage buffer 1221 and a connecting portion 1222 connecting the end of the sub-leakage buffer 1221 away from the porous substrate 21. The sub-leakage buffer 1221 and the connecting portion 1222 are made of porous materials, such as porous ceramics, porous metals, or other materials with supporting and liquid-absorbing capabilities. 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 e-liquid after condensation in the atomization chamber 125 formed by the leakage buffer structure 122 and the atomizing core 2, preventing the condensed e-liquid from leaking out through the air inlet 126.

[0059] Please see Figure 6 , Figure 6This is a schematic diagram of the third embodiment of the leakage buffer structure provided by the present invention. A base 12 has a main body 123, which includes a first sub-body 1231 and a second sub-body 1232, spaced apart and symmetrically arranged. The first sub-body 1231 and the second sub-body 1232 can be arranged parallel and perpendicularly to the base 121. In another optional embodiment, the first sub-body 1231 and the second sub-body 1232 can be arranged obliquely and symmetrically on the base 121, with the distance between the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121 being 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 materials of the first sub-body 1231 and the second sub-body 1232 are dense ceramic, dense metal, or glass, or other materials with supporting capabilities but no liquid absorption capabilities. In another specific embodiment, a leakage buffer structure 122 is disposed at the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121. The ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121 are connected to the oil transfer section 211 through the leakage buffer structure 122. The leakage buffer structure 122 can be a porous material with both supporting and liquid-absorbing capabilities. For example, the material of the leakage buffer structure 122 can be porous ceramic, porous metal, or other materials with supporting and liquid-absorbing capabilities. The leakage buffer structure 122 can collect the e-liquid leaking from the oil transfer section 211, and can also allow the e-liquid stored in the leakage buffer structure 122 to flow back to the oil transfer section 211 in contact with the leakage buffer structure 122, thereby achieving effective utilization of the stored e-liquid and realizing multiple cycles of collection and return of e-liquid. The material of the leakage buffer structure 122 can also be cotton, fiber, absorbent resin, or other materials with absorbent capabilities but no supporting capabilities. The liquid absorption capacity of the porous material used to make the leakage buffer structure 122 is less than that of the porous material used to make the oil transfer part 211.

[0060] 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 contacting the porous substrate 21 and the other end extending to the bottom of the atomizing chamber 125. The soft porous material is at least one of cotton, fiber, and resin, or it can be other materials that have liquid absorption capacity but lack support capacity.

[0061] Please see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the fourth embodiment of the leakage buffer structure provided by the present invention; Figure 8 yes Figure 7A top view of the provided leakage buffer structure. In one specific embodiment, the leakage buffer structure 122 is made of a soft porous material. The anti-leakage liquid absorption component 1227 is supported by the support portion 127, so that one end of the leakage buffer structure 122 contacts the porous substrate 21, and the other end extends to the bottom of the atomizing chamber 125. The support portion 127 includes a first sub-support 1271 and a second sub-support 1272. The first sub-support 1271 and the second sub-support 1272 are provided with a flow channel 1233, in which the leakage buffer structure 122 is provided. One end of the leakage buffer structure 122 contacts the oil transfer portion 211 in the porous substrate 21, and the other end extends to the base 121 of the lower seat 12. The flow channel 1233 can be a groove structure, and the groove size of the flow channel 1233 is larger than the size of the first capillary groove 1223. One end of the flow channel 1233 is open on the inner sidewall of the first sub-support 1271 and the second sub-support 1272, and the other end is open on the end face of the first sub-support 1271 and the second sub-support 1272 away from the base 121. The leakage buffer structure 122 filled in the flow channel 1233 is in contact with the oil transfer part 211. The cross-sectional dimension of the groove provided on the surface of the first sub-support 1271 and the second sub-support 1272 away from the base 121 is not less than the contact dimension between the oil transfer part 211 and the first sub-support 1271 and the second sub-support 1272. Specifically, the opening width of the flow channel 1233 at the end face of the first sub-support 1271 and the second sub-support 1272 in the direction of the line connecting the first sub-support 1271 and the second sub-support 1272 is not less than the contact width between the first sub-support 1271 and the second sub-support 1272 and the oil transmission part 211 in the direction of the line connecting the first sub-support 1271 and the second sub-support 1272. The leakage buffer structure 122 is disposed in 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 transmission part 211, and the other end extends between the first sub-support 1271 and the second sub-support 1272, or it can extend to the surface of the base 121. It can collect the condensate of the atomized e-liquid and prevent the atomized e-liquid from leaking out of the air inlet 126 provided on the base 121 after cooling and liquefaction, which would affect the user experience. When the pressure in the liquid storage chamber 4 decreases, the leakage buffer structure 122 can also redirect the collected e-liquid back to the oil transfer section 211 in contact with it through capillary action, thereby achieving effective utilization of the leaked liquid and enabling the leakage buffer structure 122 to collect and redirect e-liquid multiple times. The liquid absorption capacity of the leakage buffer structure 122 is less than that of the oil transfer section 211. Specifically, the liquid absorption capacity of the porous material used to make the leakage buffer structure 122 is less than that of the porous material used to make the oil transfer section 211. The leakage buffer structure 122 can be made of absorbent materials such as cotton, fiber, or absorbent resin.

[0062] When the temperature rises, the air bubbles in the e-liquid in the reservoir 4 expand, increasing the pressure in the reservoir 4. This causes the e-liquid in the atomizer core 2 to leak from the end of the oil transfer section 211 in the atomizer core 2. The leaked e-liquid flows to the leakage buffer structure 122 connected to the oil transfer section 211. The leakage buffer structure 122 collects the leaked e-liquid, and the e-liquid can permeate along the extension direction of the leakage buffer structure 122, preventing e-liquid from leaking out of the air inlet 126. When the temperature drops, the atomized e-liquid in the atomizing chamber 125 cools and forms e-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 air bubbles in the e-liquid in the storage tank 4 will shrink, reducing the pressure in the storage tank 4. As a result, due to the pressure difference between the inside and outside of the storage tank 4, the e-liquid collected and stored in the leakage buffer structure 122 flows along the direction of the leakage buffer structure 122 towards the oil transfer section 211 connected to the leakage buffer structure 122 through capillary action, thus realizing the effective utilization of the collected e-liquid.

[0063] Please see Figure 9 , Figure 9 This is a schematic diagram 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 disposed on the body 123. The first capillary groove 1223 can be disposed on any side surface of the body 123, and the opening can face 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 disposed on the surface of the base 121 near the upper seat 11 and is fixedly connected to the base 121. The body 123 can be disposed perpendicularly 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 part 211, such 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 part 211, while 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 the leaked liquid from the oil transfer section 211 and return the leaked liquid to the liquid storage tank 4, thereby preventing leakage and effectively utilizing the stored leaked liquid.

[0064] In this embodiment, the first sub-body 1231 and the second sub-body 1232 have multiple first capillary grooves 1223 on their sidewall surfaces near the atomizing chamber 125. These multiple side-by-side first capillary grooves 1223 form a leakage buffer structure 122. Specifically, the cross-section of the first capillary groove 1223 can be U-shaped, V-shaped, semi-circular, semi-elliptical, or C-shaped; its cross-sectional shape is not limited here, as long as it 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 atomizing core 2. This size refers to the width in the direction of the first sub-body 1231 and the second sub-body 1232.

[0065] The bottom of the atomizing chamber 125 is the surface of the base 121 connected to the leakage buffer structure 122. A second capillary groove 1224 is provided on the surface of the base 121 connected to the leakage buffer structure 122. The second capillary groove 1224 is disposed on the surface of the base 121 between the first sub-body 1231 and the second sub-body 1232, and communicates with the first capillary groove 1223. The first capillary groove 1223 and the second capillary groove 1224 form an L-shaped capillary groove structure. Specifically, the cross-sectional shape of the second capillary groove 1224 may be the same as or different from the cross-sectional shape of the first capillary groove 1223. There may be one second capillary groove 1224, meaning that one second capillary groove 1224 communicates with all the first capillary grooves 1223 on either the first sub-body 1231 or the second sub-body 1232. The number of second capillary grooves 1224 can be the same as the number of 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 allows e-liquid leaking from the end of the oil transfer section 211 to flow along the direction of its extension to the second capillary groove 1224, storing the leaked e-liquid and preventing it from leaking out of the air inlet 126 on the base 121. The second capillary groove 1224 can also collect condensate after the atomized e-liquid cools, preventing leakage from the air inlet 126 on the base 121 after liquefaction, thus affecting the user experience. The first capillary groove 1223 can also return the collected e-liquid to the oil transfer section 211 it contacts through capillary action, thereby achieving effective utilization of the collected leaked liquid. The liquid absorption capacity of the first capillary groove 1223 and the second capillary groove 1224 is less than that of the oil transfer section 211. Specifically, the liquid absorption capacity of the first capillary groove 1223 and the second capillary groove 1224 is less than that of the porous material used to make the oil transfer section 211.

[0066] In another specific embodiment, the leakage buffer structure 122 is also used to support the atomizing core 2. Specifically, to save space, the first sub-body 1231 and the second sub-body 1232, which are provided with the first capillary groove 1223, are also used to support the atomizing core 2. The ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121 are used to support the atomizing core 2. The oil transfer part 211 is provided at the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121, and a protrusion 212 provided on one side of the oil transfer part 211 is provided between the first sub-body 1231 and the second sub-body 1232.

[0067] Please see Figure 10 , Figure 10 This is a schematic diagram illustrating the phenomenon of the atomizer provided by the present invention during the heating process. As the temperature rises, the volume of air bubbles in the e-liquid in the reservoir 4 expands, increasing the pressure in the reservoir 4. This causes the e-liquid in the atomizer core 2 to leak from the end of the oil transfer section 211 in the atomizer core 2. The leaked e-liquid flows to the first capillary groove 1223 connected to the oil transfer section 211, where it is collected. The e-liquid can then flow along the first capillary groove 1223 on the first sub-body 1231 and the second sub-body 1232 to the second capillary groove 1224, where it is also collected, preventing the leaked e-liquid from leaking out of the air inlet 126. Please refer to [link to relevant documentation]. Figure 11 , Figure 11 This is a schematic diagram illustrating the cooling process of the atomizer provided by the present invention. As the temperature decreases, the atomized e-liquid in the atomization chamber 125, composed of the first sub-body 1231, the second sub-body 1232, the base 121, and the atomizing core 2, cools and forms e-liquid, which flows onto the base 121 and is collected through the second capillary groove 1224. Simultaneously, the volume of air bubbles in the e-liquid in the storage tank 4 decreases, reducing the pressure in the storage tank 4. Consequently, due to the pressure difference between the inside and outside of the storage tank 4, the e-liquid collected and stored in the first capillary groove 1223 and the second capillary groove 1224 flows along the first capillary groove 1223 away from the second capillary groove 1224 through capillary action to the oil transfer section 211 connected to the first capillary groove 1223. Since the oil transfer section 211 has a greater liquid absorption capacity than the first capillary groove 1223 and the second capillary groove 1224, the oil transfer section 211 can absorb the e-liquid and achieve effective utilization of the collected e-liquid.

[0068] Please see Figure 12 , Figure 12This is a schematic diagram of the sixth embodiment of the leakage buffer structure provided by the present invention. The leakage buffer structure 122 includes a body 123 and capillaries 1225 disposed on the body 123. A plurality of capillaries 1225 are provided on the first sub-body 1231 and the second sub-body 1232. One end of each capillary 1225 extends on the body 123 in a direction away from the bottom of the atomizing cavity 125 and contacts the porous substrate 21, while the other end extends in a direction close to the bottom of the atomizing cavity 125. Specifically, the cross-section of the capillary 1225 structure can be rectangular, triangular, circular, semi-circular, or elliptical; the shape of its cross-section is not limited here, as long as it facilitates drainage and collection. In an optional embodiment, the distribution width of the capillaries 1225 on the end faces of the first sub-body 1231 and the second sub-body 1232 that contact the porous substrate 21 is not less than the contact width between the first sub-body 1231 and the second sub-body 1232 and the porous substrate 21. The width is defined by the line connecting the first sub-body 1231 and the second sub-body 1232. A second capillary groove 1224 is provided on the surface of the base 121 connected to the body 123. The second capillary groove 1224 is disposed on the surface of the base 121 between the first sub-body 1231 and the second sub-body 1232, and communicates with the capillary pore 1225 structure. Specifically, the cross-sectional shape of the second capillary groove 1224 can be U-shaped, V-shaped, semi-circular, elliptical, or chamfered; its cross-sectional shape is not limited here, as long as it facilitates collection. The number of capillary pores 1225 can be one, meaning one second capillary groove 1224 communicates with all capillary pores 1225 on the first sub-body 1231 or the second sub-body 1232. The number of second capillary grooves 1224 can be the same as the number of capillary pores 1225, meaning one capillary pore 1225 communicates with a corresponding second capillary groove 1224. Leaked e-liquid can flow along the capillary pores 1225 to the second capillary groove 1224, where it is stored, preventing leakage from the air inlet 126 on the base 121. The second capillary groove 1224 also collects condensate from the cooled e-liquid, preventing leakage from the air inlet 126 after liquefaction, thus improving the user experience. The capillary pores 1225 can also channel the collected e-liquid back to the oil transfer section 211 through capillary action, effectively utilizing the collected liquid and extending the lifespan of the second capillary groove 1224. The liquid absorption capacity of the capillary pores 1225 and the second capillary groove 1224 is less than that of the oil transfer section 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 used to make the oil transfer section 211.

[0069] When the temperature rises, the air bubbles in the e-liquid in the reservoir 4 expand, increasing the pressure in the reservoir 4. This causes the e-liquid in the atomizer core 2 to leak from the end of the oil transfer section 211. The leaked e-liquid flows to the capillary pore 1225 connected to the oil transfer section 211, where it is collected. The e-liquid then flows along the capillary pore 1225 on the first sub-body 1231 and the second sub-body 1232 to the second capillary groove 1224, where it is also collected, preventing leakage from the air inlet 126. When the temperature drops, the atomized e-liquid in the atomizing chamber 125 cools and forms e-liquid, which flows onto the base 121 and is collected by the second capillary groove 1224. Simultaneously, the volume of air bubbles in the e-liquid in the storage tank 4 will shrink, reducing the pressure in the storage tank 4. Consequently, due to the pressure difference between the inside and outside of the storage tank 4, the e-liquid collected and stored in the capillary pores 1225 and the second capillary groove 1224 flows along the direction away from the second capillary groove 1224 through capillary action to the oil transfer section 211 connected to the capillary pores 1225. Since the oil transfer section 211 has a greater liquid absorption capacity than the capillary pores 1225 and the second capillary groove 1224, the oil transfer section 211 can absorb the e-liquid and achieve effective utilization of the collected e-liquid.

[0070] In another optional embodiment, the leakage buffer structure 122 includes a first capillary groove 1223 and a soft porous material, the soft porous material being filled in the first capillary groove 1223, and the liquid absorption capacity of both the first capillary groove 1223 and the soft porous material being less than the liquid absorption capacity of the porous substrate 21.

[0071] In another optional embodiment, the leakage buffer structure 122 includes capillary pores 1225 and a soft porous material. The capillary pores 1225 are filled with the soft porous material, and the liquid absorption capacity of both the capillary pores 1225 and the soft porous material is less than the liquid absorption capacity of the porous matrix 21.

[0072] The atomizer provided in this embodiment includes a liquid storage chamber for storing liquid; a mounting base including a leakage buffer structure with capillary action; and an atomizing core including a porous substrate and a heating element. The porous substrate is in fluid communication with the liquid storage chamber and adsorbs liquid from the liquid storage chamber through capillary action. The heating element heats and atomizes the liquid in the porous substrate. The atomizing core is located between the liquid storage chamber and the leakage buffer structure. The leakage buffer structure abuts against the porous substrate to receive liquid overflowing from the porous substrate. In the atomizer provided by this invention, the leakage buffer structure can collect liquid leaking from the liquid storage chamber, preventing leakage from the atomizer's air inlet. The leakage buffer structure and the atomizing core can, through capillary action, return the liquid stored in the leakage buffer structure to the atomizing core, achieving effective utilization of the leakage. Multiple cycles can further prevent atomizer leakage and improve the user experience.
