[0045] Please refer to Figure 1 , Figure 1 is a three-dimensional structural schematic diagram of an electronic atomization device 10 provided by the present application.

[0046] The electronic atomization device 10 can be used for atomizing a liquid to be atomized. The electronic atomization device 10 includes an atomizer 20 and a main unit 30 which are connected to each other, and the main unit 30 supplies power to the atomizer 20. The atomizer 20 and the main unit 30 can be integrally provided or detachably connected, and can be designed according to specific needs. In this embodiment, the atomizer 20 and the main unit 30 are detachably provided.

[0047] Among them, the atomizer 20 is used to store the liquid to be atomized and atomize the liquid to be atomized to form an aerosol. The atomizer 20 can be specifically used in different fields, such as medical, electronic aerosol atomization devices, etc.; in a specific embodiment, the atomizer 20 can be used in an aerosol atomization device to atomize the liquid to be atomized and generate an aerosol for a smoker to inhale. The following embodiments are all based on this example; of course, in other embodiments; or applied to medical devices for treating upper and lower respiratory diseases to atomize medical drugs.

[0048] For the specific structure and function of the atomizer 20, reference can be made to the specific structure and function of the atomizer 20 involved in any of the following embodiments, and the same or similar technical effects can be achieved, which will not be elaborated here.

[0049] Please refer to Figure 2 , Figure 2 is Figure 1 a cross-sectional view of the electronic atomization device 10 along the A-A direction.

[0050] The main unit 30 includes a housing 31, a liquid supply component 32, a battery 33, a mounting bracket 34, and a control device (not shown in the figure). The control device can be, for example, a circuit board or a chip. Among them, the liquid supply component 32, the battery 33, the mounting bracket 34, and the control device are all arranged in the housing 31, and the liquid supply component 32, the control device, and the battery 33 are all arranged on the mounting bracket 34 to realize the installation and connection of the liquid supply component 32, the battery 33, and the control device.

[0051] The battery 33 is used to supply power to the atomizer 20 and the liquid supply component 32. The control device has a control circuit, and the control circuit is electrically connected to both the battery 33 and the liquid supply component 32 to control the battery 33 to supply power to the liquid supply component 32 and the atomizer 20, control the liquid supply component 32 to supply liquid to the atomizer 20, and control the atomizer 20 to atomize.

[0052] Specifically, the liquid supply component 32 is used to supply liquid to the atomizer 20. In this embodiment, the liquid supply component 32 is used to supply liquid to the atomizer 20 when the user inhales. For example, a suction detection element can be provided in the electronic atomization device 10, and the suction detection element is electrically connected to the control circuit. The suction detection element is used to detect the user's suction action. The suction detection element can be, for example, an airflow sensor, a microphone, or other detection elements.

[0053] The control circuit can detect the user's puffing state according to the user's puffing action. When the control circuit detects that the user starts puffing, it controls the liquid supply assembly 32 to supply liquid to the atomizer 20; when the control circuit detects that the user stops puffing, it controls the liquid supply assembly 32 to stop supplying liquid to the atomizer 20. By the above method, when the user does not puff, there is no liquid to be atomized in the buffer chamber 224 inside the atomizer 20, preventing the atomizer 20 from leaking liquid during carrying or transportation.

[0054] In other words, the electronic atomization device 100 is an instant liquid supply type. When the electronic atomization device 100 is in a non-working state, the buffer chamber 224 is basically in a vacant state, that is, there is very little liquid retained in it; when the electronic atomization device 100 is in a working state, the liquid supply assembly 32 instantaneously supplies a certain amount of liquid into the buffer chamber 224, and when the user stops puffing, there is very little liquid retained in the buffer chamber 224, so that the buffer chamber 224 can be basically kept in a vacant state due to the very small amount of liquid retained in it when in the non-working state.

[0055] Furthermore, the liquid supply assembly 32 includes a liquid injection tube 321, a liquid pumping pump 322 and an oil supply bottle 323. The liquid pumping pump 322 is connected to the oil supply bottle 323, and the liquid pumping pump 322 is also connected to the liquid injection tube 321 and is used to pump the atomization liquid stored in the oil supply bottle 323 to the liquid injection tube 321 to inject liquid into the atomizer 20 through the liquid injection tube 321.

[0056] The oil supply bottle 323 stores the atomization liquid. The oil supply bottle 323 can be made of metals such as aluminum and stainless steel, or can be made of plastic, as long as it can store the atomization liquid and does not react with the atomization liquid. The shape, size and position of the oil supply bottle 323 are not limited and can be designed according to needs. The oil supply bottle 323 in this embodiment is detachable to facilitate re-filling or replacement of the oil supply bottle 323 when the liquid storage in the oil supply bottle 323 is insufficient.

[0057] When the user puffs, the liquid injection tube 321 can also be used to detect whether the buffer chamber 224 of the atomizer 20 needs to be refilled. A liquid level detection device or a liquid level detection circuit can be integrated on the liquid injection tube 321. Furthermore, while injecting liquid, parameters such as the conductivity and hydraulic pressure of the liquid in the buffer chamber 224 of the atomizer 20 can also be detected, and then the liquid level value can be obtained and fed back to the control device. The control device can regulate the liquid supply assembly 32 to inject liquid into the atomizer 20 according to the fed-back liquid level signal; or, the liquid level detection circuit on the liquid injection tube 321 is open when the liquid level in the buffer chamber 224 is lower than a certain threshold, and then the control device can inject liquid into the buffer chamber 224 accordingly, such as injecting a certain amount of liquid or injecting liquid for a certain period of time; the liquid level detection circuit on the liquid injection tube 321 is conductive when the liquid level in the buffer chamber 224 reaches or is higher than a certain threshold.

[0058] The liquid extraction pump 322 is electrically connected to the control circuit of the controller. When the controller detects that the user starts to aspirate, it sends a control signal to the liquid extraction pump 322 to cause the liquid extraction pump 322 to inject liquid into the buffer chamber 224. Moreover, during the aspiration process, when the liquid level detector 321 detects that the liquid level in the buffer chamber 224 is lower than the first liquid level value, the liquid extraction pump 322 can control the liquid injection pipe 321 to inject liquid into the buffer chamber 224, and stop injecting liquid when the liquid level detector 321 detects that the liquid level in the buffer chamber 224 reaches the second liquid level value.

[0059] In other embodiments, the main body 30 may not include the above-mentioned liquid supply assembly 32, and it only provides energy to the atomizer 20 without supplying liquid. That is, the liquid supply assembly 32 can be provided independently of the main body 30. For example, the user can supply liquid manually.

[0060] Please refer to Figure 3 , Figure 3 FIG. 10 is a schematic perspective view of a three-dimensional structure of the main body 30 provided in this embodiment. Among them, in this embodiment, the mounting bracket 34 is installed inside the housing 31, and a receiving cavity 312 is formed in cooperation with the housing 31. The receiving cavity 312 is used to accommodate the atomizer 20 to realize the assembly of the atomizer 20 and the main body 30.

[0061] The liquid injection pipe 321 and the electrode 35 are also provided on the mounting bracket 34 and exposed to the receiving cavity 312. The electrode 35 is electrically connected to the battery 33. When the atomizer 20 is assembled in the receiving cavity 312, one end of the liquid injection pipe 321 exposed in the receiving cavity 312 can be inserted into the atomizer 20 to realize the liquid supply of the liquid injection pipe 321 to the atomizer 20, and at the same time, the electrode 35 is electrically connected to the atomizer 20 to realize the electrical connection between the atomizer 20 and the main body 30.

[0062] An air inlet groove 341 and an air inlet 3411 are provided on the mounting bracket 34. The air inlet 3411 communicates the air inlet groove 341 with the outside atmosphere. The air inlet groove 341 is exposed to the receiving cavity 312. When the atomizer 20 is assembled in the receiving cavity 312, the air inlet groove 341 is communicated with the air inlet hole 261 of the atomizer 20 so that air can enter the atomizer 20 through the air inlet groove 341.

[0063] An adjusting member 36 is also installed in the air inlet groove 341. The adjusting member 36 is used to adjust the size of the air inlet 3411, so as to control the size of the air flow entering the atomizer 20. The adjusting member 36 can completely close the air inlet 3411 or completely open the air inlet 3411. The structures of the air inlet groove 341, the air inlet 3411 and the adjusting member 36 are not limited and can be designed according to needs.

[0064] An airflow sensor 37 is also provided inside the mounting bracket 34. The airflow sensor 37 detects the airflow flowing through the air intake groove 341 through a detection hole provided in the air intake groove 341 to confirm whether the user is sucking the electronic atomization device 10. Specifically, when the airflow sensor 37 detects the flow of the airflow in the air intake groove 341, it can be confirmed that the user is sucking and using the electronic atomization device 10. Thereby, the control device sends a signal to supply power to the atomizer 20, and sends a signal to the liquid supply assembly 32 to control the liquid supply assembly 32 to supply liquid to the atomizer 20, so that the atomizer 20 atomizes the liquid to be atomized into an aerosol; when the airflow sensor 37 does not detect the flow of the airflow in the air intake groove 341, the control device sends a signal to stop power supply or maintain the state of power supply being stopped, and sends a signal to control the liquid supply assembly 32 to stop liquid supply or perform a back suction.

[0065] Please refer to Figure 4 , Figure 4 as Figure 2 the enlarged schematic view of B in. In this embodiment, an atomizer 20 is provided. The atomizer 20 includes a housing 21, a buffer assembly 22 and an atomization assembly 23. Among them, the buffer assembly 22 and the atomization assembly 23 are arranged inside the housing 21.

[0066] Specifically, a ventilation hole 212 is provided on the housing 21. The buffer assembly 22 and the atomization assembly 23 are both assembled inside the housing 21. The pressure relief channel 2212 on the buffer assembly 22 is communicated with the outside atmosphere through the ventilation hole 212 to reduce the pressure in the buffer cavity 224 through the pressure relief channel 2212 and the ventilation hole 212, which is beneficial to prevent the liquid in the atomizer 20 from entering the air flow channel 233 in the atomization assembly 23 due to too high pressure during the liquid injection process, resulting in liquid leakage during suction.

[0067] Furthermore, the buffer assembly 22 and the housing 21 cooperate to form a pressure relief cavity 211. The pressure relief cavity 211 is located between the pressure relief channel 2212 and the ventilation hole 212. The pressure relief channel 2212, the pressure relief cavity 211 and the ventilation hole 212 are communicated in sequence. The pressure relief cavity 211 can be used to accommodate and buffer the liquid discharged through the pressure relief channel 2212, avoiding waste and pollution caused by the liquid being discharged to the outside of the atomizer 20, and being beneficial to further prevent the liquid in the atomizer 20 from entering the air flow channel 233 due to pressurization.

[0068] In this embodiment, the buffer assembly 22 receives and stores the liquid to be atomized provided by the liquid injection tube 321 during the user's suction.

[0069] In other embodiments, for example, if the main unit 30 does not include the liquid supply assembly 32, the liquid to be atomized stored in the buffer assembly 22 can also be added manually.

[0070] Specifically, please refer to Figure 4 and Figure 5 , Figure 5A cross-sectional view of the buffer component 22 provided in this embodiment. The buffer component 22 is provided with an assembly hole 2211, a buffer chamber 224, and a pressure relief passage 2212. Both the assembly hole 2211 and the pressure relief passage 2212 communicate with the buffer chamber 224.

[0071] In this embodiment, the buffer component 22 includes a pressure relief member 221 and a base 222. The pressure relief member 221 is provided with an assembly hole 2211 and a pressure relief passage 2212. The base 222 is assembled to one end of the pressure relief member 221 close to the host 30, and the base 222 and the pressure relief member 221 cooperate to form the buffer chamber 224.

[0072] Specifically, a liquid storage tank 2216 is provided on the side of the pressure relief member 221 facing the base 222, and the base 222 covers the liquid storage tank 2216 to form the buffer chamber 224.

[0073] Optionally, a liquid storage tank 2216 is provided on the side of the base 222 facing the pressure relief member 221, and the pressure relief member 221 covers the liquid storage tank 2216 to form the buffer chamber 224; or, the buffer component 22 is an integral structural member, and a buffer chamber 224 is provided therein.

[0074] The pressure relief passage 2212 and the assembly hole 2211 are arranged in parallel on one side of the buffer chamber 224 and are respectively communicated with the bottom of the buffer chamber 224. The atomization component 23 is arranged in the assembly hole 2211, and the atomization component 23 is in contact with the buffer chamber 224 to absorb and atomize the liquid in the buffer chamber 224.

[0075] In this embodiment, the atomization component 23 is inserted through the buffer chamber 224; in other embodiments, a side wall of the atomization component 23 can also form a side wall of the buffer chamber 224, so that the liquid stored in the buffer chamber 224 can also be absorbed by the atomization component 23.

[0076] The pressure relief passage 2212 is in fluid communication with the buffer chamber 224 and the atomization component 23, that is, the liquid in the buffer chamber 224 can also be guided to the atomization component 23 through the pressure relief passage 2212 and be absorbed by the atomization component 23, and the pressure relief passage 2212 communicates with the atmosphere, so that the pressure relief passage 2212 has the function of relieving pressure when injecting liquid into the buffer chamber 224, and exporting the excess liquid when the liquid in the buffer chamber 224 is overloaded, so as to prevent the liquid in the buffer chamber 224 from entering the air flow passage 233 of the atomization component 23 due to pressurization.

[0077] The pressure relief passage 2212 is in communication with the buffer chamber 224 and is also in communication with the atmosphere, so as to discharge the gas in the buffer chamber 224 through the pressure relief passage 2212 when injecting liquid into the buffer chamber 224, thereby relieving the pressure of the buffer chamber 224; and when the liquid injection is overloaded, the pressure relief passage 2212 can also store the overloaded liquid, and further can direct the overloaded liquid to the atomizing assembly 23. If there is too much overloaded liquid, the liquid can also be discharged into the pressure relief chamber 211 to store the liquid in the pressure relief chamber 211. The liquid in the pressure relief chamber 211 can also be directed to the atomizing assembly 23 through the pressure relief passage 2212, and thus can be consumed by the atomizing assembly 23.

[0078] By venting and relieving the pressure of the buffer chamber 224, effectively preventing the buffer chamber 224 from pressurizing the liquid in the atomizing assembly 23 during the oil supply process, and further preventing the problem of suction liquid leakage caused by the liquid in the atomizing assembly 23 entering the air flow passage 233 due to pressurization.

[0079] In this application, fluid communication means that the fluid in the buffer chamber 224 can flow through the pressure relief passage 2212 to the other end of the atomizing assembly 23, and the fluid can be gas or liquid. By means of fluid communication between the buffer chamber 224 and the end of the atomizing assembly 23 outside the buffer chamber 224 through the pressure relief passage 2212, when the liquid in the buffer chamber 224 is overloaded, the excess liquid can be exported to the pressure relief passage 2212 and flow back from the pressure relief passage 2212 to the end of the atomizing assembly 23 outside the buffer chamber 224, improving the utilization rate of the liquid to be atomized and reducing the waste of the liquid to be atomized.

[0080] In other embodiments, the buffer assembly 22 can be filled with a liquid storage member to store the liquid to be atomized by using the liquid storage member; the atomizing assembly 22 is in communication with the buffer assembly 23, that is, the atomizing assembly 23 is in contact with the liquid storage member, and thus can absorb the liquid to be atomized in the liquid storage member. The pressure relief passage 2212 is also in communication with the liquid storage member and the atomizing assembly 23.

[0081] The liquid storage member can be absorbent cotton or absorbent paper, etc. That is, the liquid storage member can replace the above-mentioned buffer chamber 224, and thus there is no need to provide a buffer chamber 224 in the buffer assembly 22.

[0082] In one embodiment, please refer to Figure 4 and Figure 5 , the pressure relief passage 2212 includes a microporous portion 2212a, a first pressure relief groove 2212b and a second pressure relief groove 2212c. The first pressure relief groove 2212b and the second pressure relief groove 2212c are disposed on opposite sides of the microporous portion 2212a. One end of the first pressure relief groove 2212b is in communication with the buffer chamber 224, and the other end is in communication with the microporous portion 2212a; one end of the second pressure relief groove 2212c is in communication with the microporous portion 2212a, and the other end is in communication with the pressure relief chamber 211.

[0083] Specifically, the first pressure relief groove 2212b is arranged at the bottom of the liquid storage tank 2216, and the bottom of the first pressure relief groove 2212b is communicated with the microporous portion 2212a; the second pressure relief groove 2212c is arranged on the surface of the pressure relief member 221 away from the liquid storage tank 2216, and the bottom of the second pressure relief groove 2212c is communicated with the microporous portion 2212a. By arranging the first pressure relief groove 2212b and the second pressure relief groove 2212c, the amount of liquid contained in the pressure relief channel 2212 can be increased, which is conducive to guiding more excess liquid in the buffer cavity 224 to the pressure relief channel 2212, and preventing the problem of suction leakage caused by the pressurization of the atomization component 23 by the buffer cavity 224.

[0084] Specifically, the microporous portion 2212a is used to block the liquid in the buffer cavity 224 from passing through under normal pressure, that is, the liquid in the buffer cavity 224 cannot pass through the microporous portion 2212a under normal pressure. The microporous portion 2212a includes a plurality of micropores, which are capillary pores and have a strong capillary force, thereby preventing the liquid in the buffer cavity 224 from passing through the pressure relief channel 2212 under normal pressure.

[0085] During the suction process, when there is liquid in the buffer cavity 224, due to the small aperture of the micropores, even if the atomizer 20 is tilted during suction, the liquid in the buffer cavity 224 can remain in the buffer cavity 224 under the action of surface tension, and does not enter the second pressure relief groove 2212c. The micropore portion 2212a can block the liquid in the buffer cavity 224 from passing under normal pressure, and can prevent the liquid in the buffer cavity 224 from flowing to the end of the pressure relief channel 2212 away from the buffer cavity 224 due to the tilt when the atomizer 20 is tilted, thereby preventing the problem of the liquid detection element failing when detecting the liquid level in the buffer cavity 224 and supplying liquid to the buffer cavity 224 multiple times.

[0086] During the process of injecting liquid into the buffer chamber 224, the microporous portion 2212a can relieve pressure, and when the buffer chamber 224 is filled, under strong hydraulic pressure, the liquid can also be discharged through the microporous portion 2212a, thereby preventing the liquid in the buffer chamber 224 from entering the air flow channel 233 of the atomizer assembly 23 due to pressurization.

[0087] In other embodiments, the structure of the pressure relief channel 2212 may also include only the microporous portion 2212a and the second pressure relief groove 2212c, excluding the first pressure relief groove 2212b; the structure of the pressure relief channel 2212 may also include only the second pressure relief groove 2212c, excluding the first pressure relief groove 2212b and the microporous portion 2212a; the structure of the pressure relief channel 2212 may also include only the microporous portion 2212a, excluding the first pressure relief groove 2212b and the second pressure relief groove 2212c. The structure of the pressure relief channel 2212 may also be other structures, not limited to the structure provided in this embodiment.

The liquid accumulation member 223 is used to store the liquid discharged through the pressure relief passage 2212, and return the stored and locked liquid to the atomization assembly 23 for atomization by contacting the atomization assembly 23, so as to improve the utilization rate of the liquid and reduce the waste of the liquid.

[0091] The liquid accumulation member 223 can be a porous material and can absorb a large amount of liquid to be atomized. The material of the liquid accumulation member 223 can be, for example, absorbent cotton, porous ceramics, etc. In this embodiment, the material of the liquid accumulation member 223 is absorbent cotton.

[0092] A pressure relief hole 2231 is further provided in the liquid accumulation member 223. The pressure relief hole 2231 is located on the gas path of the pressure relief passage 2212, that is, the pressure relief hole 2231 can be used as a part of the pressure relief passage 2212. In this embodiment, one end of the pressure relief hole 2231 communicates with the second pressure relief groove 2212c, and the other end communicates with the pressure relief chamber 211, so that gas can pass through the liquid accumulation member 223, preventing the liquid accumulation member 223 from blocking the pressure relief passage 2212 due to liquid absorption and causing the inability to discharge excessive air pressure.

[0093] Optionally, the liquid accumulation member 223 and the side wall of the assembly groove 2213 cooperate to form a pressure relief hole 2231. The side wall of the liquid accumulation member 223 or the assembly groove 2213 is provided with a groove structure, and the liquid accumulation member 223 and the assembly groove 2213 cooperate to form the pressure relief hole 2231; alternatively, the pressure relief member 221 is provided with a pressure relief hole 2231, and the pressure relief hole 2231 communicates the second pressure relief groove 2212c with the pressure relief cavity 211.

[0094] By providing the liquid accumulation member 223 in the pressure relief channel 2212, the liquid flowing from the buffer cavity 224 to the pressure relief channel 2212 can be absorbed by the liquid accumulation member 223, preventing the liquid in the pressure relief channel 2212 from leaking out of the atomizer 20 through the vent hole 212 of the housing 31. Moreover, the liquid accumulation member 223 is also in contact with the atomization assembly 23, and the liquid accumulation member 223 can return the liquid to the atomization assembly 23, improving the utilization rate of the liquid to be atomized and preventing the waste of the liquid to be atomized.

[0095] Please refer to Figure 6 , further, in this embodiment, the liquid accumulation member 223 includes an embedding portion 2232 and an abutting portion 2233 provided on one side of the embedding portion 2232.

By configuring the liquid accumulation member 223 in the above structure, on the one hand, the embedding portion 2232 is disposed in the pressure relief channel 2212 and can absorb the liquid in the pressure relief channel 2212; on the other hand, by making the abutting portion 2233 abut against the atomization assembly 23, the liquid in the embedding portion 2232 can be guided to the side wall of the atomization assembly 23 through the abutting portion 2233, so as to realize the return of the liquid in the pressure relief channel 2212 to the atomization assembly 23, improving the utilization rate of the liquid to be atomized and preventing the waste of the liquid to be atomized. In other embodiments, the liquid accumulation member 223 may also only include the abutting portion 2233 or only include the embedding portion 2232, and is not limited to the above structural form.

[0096] Further, please refer to Figure 4 and Figure 7 , Figure 7 is a schematic structural diagram of the atomization assembly 23 provided by an embodiment of the present application. The atomization assembly 23 includes a liquid absorption member 231, a mounting member 232, a porous matrix 236, a heating member 234, and a connection lead 235. The mounting member 232 is in a cylindrical shape, the porous matrix 236 is also in a cylindrical shape and is assembled in the cylinder of the mounting member 232. The heating member 234 is disposed on the porous matrix 236, the connection lead 235 is electrically connected to the heating member 234, and the liquid absorption member 231 is disposed around the outside of the mounting member 232 and contacts the porous matrix 236 to conduct liquid to the porous matrix 236.

[0097] Among them, the porous matrix 236 can store and guide the liquid to be atomized. The material of the porous matrix 236 can be a porous ceramic, a cotton layer, a fiber layer or other porous materials. In this embodiment, the material of the porous matrix 236 is a porous ceramic. The shapes of both the porous matrix 236 and the mounting member 232 can be hollow tubular with both ends open, specifically but not limited to cylindrical. In this embodiment, the porous matrix 236 and the mounting member 232 are hollow cylindrical.

[0098] The internal space of the porous matrix 236 and the internal space of the mounting member 232 cooperate to form an air flow channel 233. One end of the air flow channel 233 far from the main body 30 is communicated with the air outlet channel 24 of the atomizer 20, and one end of the air flow channel 233 close to the main body 30 is communicated with the air inlet hole 261 of the atomizer 20. Thus, the air flowing into the air inlet hole 261 of the atomizer 20 can flow through the air flow channel 233 of the atomization assembly 23 and carry the aerosol atomized by the atomization assembly 23 out of the air outlet channel 24 of the atomizer 20.

[0099] The heating element 234 is arranged on the inner wall of the porous matrix 236. After being energized, the heating element 234 generates heat and heats the liquid to be atomized guided by the porous matrix 236 to generate aerosol. The connection lead 235 is electrically connected to the heating element 234 and the electrode 35 of the main body 30, so that the heating element 234 is electrically connected to the battery 33 and the control device of the main body 30. Thus, the battery 33 can provide power for the heating element 234, and the control circuit can control the heating duration, heating power, etc. of the heating element 234. The heating element 234 can be a thin film metal heating film, or a heating sheet, a heating mesh, a heating wire, etc. In this embodiment, the heating element is a metal heating film.

[0100] The liquid absorbing member 231 is used to store and guide the liquid to be atomized in the buffer cavity 224. The material of the liquid absorbing member 231 can be a porous ceramic, a cotton layer, a fiber layer or other porous materials. In this embodiment, the material of the liquid absorbing member 231 is a cotton layer.

[0101] One end of the mounting member 232 close to the base 222 is inserted into the base 222. The liquid absorbing member 231 is sleeved on the outer side walls of the porous matrix 236 and the mounting member 232. Moreover, there are a plurality of liquid inlet holes on the side wall of the mounting member 232. The liquid absorbing member 231 is in contact with the porous matrix 236 through the liquid inlet holes to guide the liquid in the liquid absorbing member 231 into the porous matrix 236.

[0102] Specifically, at least part of the liquid absorbing member 231 is in contact with at least part of the liquid accumulating member 223.

[0103] In this embodiment, one end of the liquid absorption member 231 close to the buffer cavity 224 is inserted into the buffer cavity 224, so that the liquid to be atomized in the buffer cavity 224 can flow into the liquid absorption member 231. The other end of the liquid absorption member 231 far from the buffer cavity 224, that is, the end of the liquid absorption member 231 close to the assembly groove 2213, contacts the abutting portion 2233 of the liquid accumulation member 223, so that the liquid in the pressure relief channel 2212 absorbed by the liquid accumulation member 223 can be guided into the liquid absorption member 231 of the atomization assembly 23, and then guided onto the heating element 234 of the porous substrate 236. Effectively, the liquid in the pressure relief channel 2212 is returned to the atomization assembly 23 and utilized, improving the utilization rate of the liquid to be atomized and preventing the waste of the liquid to be atomized.

[0104] Please refer to Figure 5 and Figure 6 , in one embodiment, the pressure relief member 221 is further provided with a liquid collection groove 2215. The liquid collection groove 2215 is arranged on the side wall of the assembly hole 2211 and surrounds the liquid absorption member 231 of the atomization assembly 23. Specifically, the liquid collection groove 2215 has the same height as the notch 2214 and is communicated with the assembly groove 2213 through the notch 2214. The inner diameter of the liquid collection groove 2215 can be larger than the inner diameter of the assembly hole 2211, so that there is a liquid collection cavity (not shown in the figure) between the inner wall of the liquid collection groove 2215 and the outer wall of the atomization assembly 23. Part of the liquid in the liquid accumulation member 223 can flow into the liquid collection cavity. The liquid collection cavity is arranged around the outer periphery of the atomization assembly 23, so that the liquid in the liquid accumulation member 223 can be quickly guided to the outer periphery of the liquid absorption member 231, which is beneficial to the uniform guiding of the liquid into the porous substrate 236.

[0105] Please refer to Figure 8 and Figure 9 , Figure 8 is Figure 2 the enlarged schematic view of the B position in Figure 9 and is the structural schematic view of the seal 25 provided in this embodiment. In one embodiment, the base 222 is provided with a first liquid injection hole 2221, and the first liquid injection hole 2221 is correspondingly arranged with the buffer cavity 224. The atomizer 20 further includes a seal 25 and a base 26. The base 26 is arranged on the side of the base 222 away from the pressure relief member 221, and the seal 25 is arranged between the base 26 and the pressure relief member 221 to seal the pressure relief assembly.

The seal 25 further includes a cover portion 252 which surrounds the periphery of the end of the second liquid injection hole 251 close to the first liquid injection hole 2221. The cover portion 252 seals the second liquid injection hole 251, and the cover portion 252 can be broken through to inject liquid into the buffer cavity 224 through the second liquid injection hole 251.

[0107] For example, the cover portion 252 can be pierced or lifted to connect the second liquid injection hole 251 and the first liquid injection hole 2221.

[0108] In this embodiment, the cover portion 252 is formed with a cut groove 253 at the end of the second liquid injection hole 251. For example, it can be a cross-shaped cut groove 253, or other shaped cut grooves 253, so that the cover portion 253 can be cut into multiple closed cover blocks 257. When no external force is applied to the cover portion 252, the multiple cover blocks 257 can automatically close to seal the end of the second liquid injection hole 251 close to the first liquid injection hole 2221, so as to prevent the liquid inside the atomizer 20 from leaking out of the atomizer 20 through each liquid injection hole. When an external force in the axial direction is applied to the liquid injection tube 321 on the cover portion 252, the cover portion 252 can be lifted by the liquid injection tube 321, that is, each cover block 257 is lifted to break the closed state, so that the liquid injection tube 321 can be inserted into the first liquid injection hole 2221 and the buffer cavity 224 through the second liquid injection hole 251, and then inject liquid into the buffer cavity 224.

[0109] In other embodiments, the cover portion 252 can also be integral, for example, it is a layer of film, and it can be pierced by the liquid injection tube 321 to pass through the second liquid injection hole 251.

[0110] By providing the cover portion 252 on the seal 25, it can effectively achieve that the liquid injection tube 321 can be smoothly inserted into the buffer cavity 224 of the atomizer 20 for liquid injection, and can seal the second liquid injection hole 251 after the liquid injection tube 321 is pulled out, effectively preventing the liquid from leaking out of the atomizer 20.

[0111] In one embodiment, a sealing rib 254 is further provided in the seal 25, and the sealing rib 254 is arranged on the inner side wall of the second liquid injection hole 251. The sealing rib 254 can be integrally formed with the second liquid injection hole 251, or can be arranged on the inner side wall of the second liquid injection hole 251 by means of glue, etc. For example, the sealing rib 254 can be a convex ring arranged around the inner side wall of the second liquid injection hole 251 for one week. During the process of supplying oil by inserting the oil supply tube into the atomizer 20, the sealing rib 254 can seal the periphery of the oil supply tube to prevent the liquid from leaking out of the atomizer 20 into the main unit 30 during the oil supply process, and further prevent phenomena such as short circuit of the main unit 30.

An opening 255 is provided in the seal 25, and the opening 255 is correspondingly arranged and communicated with the air flow channel 233 in the atomization assembly 23. An air inlet hole 261 is provided on the base 26. One end of the air inlet hole 261 of the base 26 is communicated with the air inlet groove 341 of the main body 30, and the other end is communicated with the opening 255 of the seal 25, so that the air inlet hole 261 is communicated with the air flow channel 233 of the atomization assembly 23, and air can enter the atomizer 20 from the air inlet hole 261 and carry the aerosol in the air flow channel 233 out from the air outlet channel 24.

[0113] Please refer to Figure 8 In one embodiment, a liquid collecting groove 262 is further provided on the base 26, and the liquid collecting groove 262 is located below the mounting hole 2222. When the aerosol generated in the atomization assembly 23 encounters cold air flow, condensate will be generated. The condensate flows along the atomization assembly 23 and the seal 25 to the liquid collecting groove 262 on the base 26. In order to reuse the condensate, a reflux portion 256 is further provided in the seal 25, and the reflux portion 256 is arranged in parallel with the opening 255 of the seal 25. In this embodiment, the reflux portion 256 is a reflux hole formed in the thickness direction of the seal 25. In other embodiments, the reflux portion 256 may also be a reflux groove, and the reflux groove may cooperate with the mounting member 232 to form a reflux hole.
