[0006] In some embodiments, the atomizer includes:

[0007] A liquid storage tank having the liquid storage cavity and a liquid passage communicating with the liquid storage cavity;

[0008] The atomizing chamber includes an atomizing shell and the atomizing assembly. The atomizing shell has a buffer chamber and an atomizing chamber separated by a partition. The partition has a second liquid hole. The atomizing shell has a plug-in part with a first liquid hole. The plug-in part is connected to the liquid passage hole to connect the liquid storage chamber and the buffer chamber.

[0009] In some embodiments, the volume of the buffer chamber is smaller than the volume of the liquid storage chamber, and the volume of the buffer chamber is 0.5 mL to 2.5 mL.

[0010] In some embodiments, the atomizing chamber further includes a cavity seat, a base, and a liquid suction element. The cavity seat is installed inside the atomizing housing and connected to the partition. The cavity seat and the atomizing housing define the buffer chamber. The cavity seat has an inclined surface that guides the aerosol matrix to flow toward the second liquid hole. The base is connected to the bottom of the atomizing housing and is used to fix the cavity seat in conjunction with the atomizing housing. The liquid suction element is installed on the base and is disposed corresponding to the atomizing assembly.

[0011] In some embodiments, the liquid storage chamber includes a liquid storage shell, a vent pipe seat, and a sealing seat. The vent pipe seat is connected to the liquid storage shell and together defines the liquid storage cavity. The sealing seat includes a sealing post, which is inserted into the liquid passage hole of the vent pipe seat, and the insertion part is used to be inserted into the sealing post.

[0012] In some embodiments, the sealing seat includes a sealing sheet disposed in the through hole of the sealing post, the sealing sheet sealing the liquid passage hole before being damaged; the insertion portion is used to pierce the sealing sheet and connect to the liquid passage hole.

[0018] The beneficial effects of this application are as follows: Unlike the prior art, this application discloses an electronic atomizing device and its atomizer. In this application, the aerosol matrix is ​​stored in a divided liquid storage chamber and a buffer chamber, with only the buffer chamber directly supplying liquid to the atomizing component, while the liquid storage chamber does not directly supply liquid to the atomizing component. Therefore, when storing the same volume of aerosol matrix as existing products, the hydraulic pressure and impact force generated by the buffer chamber on the atomizing component and its connections is greatly reduced, effectively lowering the risk of leakage in the atomizer provided in this application.

[0027] This application provides an electronic atomizing device 300, see reference. Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the electronic atomizing device provided in this application.

[0028] The electronic atomizing device 300 includes a main unit 200 and an atomizer 100. The main unit 200 is connected to the atomizer 100 and supplies power to the atomizer 100.

[0029] The electronic atomizing device 300 can be used to atomize aerosol matrices such as e-liquid, medicinal liquid, or nutrient solution, that is, to atomize liquid aerosol matrices into aerosols for users to inhale. The main unit 200 can be detachably connected to the atomizer 100 and supply power to the atomizer 100, thus allowing the atomizer 100 to be replaced; alternatively, the main unit 200 and the atomizer 100 can be integrated into one unit and supply power to the atomizer 100. The atomizer 100 stores and atomizes the aerosol matrix to form an aerosol for the user to inhale.

[0030] The main unit 200 includes an electrically connected control element and a battery. The control element is also used to electrically connect to the atomizer 100 to identify the status information of the atomizer 100 and control the power supply to the atomizer 100 based on the identified status information.

[0031] See Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of an embodiment of the atomizer provided in this application. Figure 3 yes Figure 2 The diagram shows a cross-sectional view of the atomizer in which the liquid storage chamber and the atomizing chamber are separated.

[0032] The atomizer 100 includes a liquid storage chamber 101, a buffer chamber 201, and an atomizing chamber 202. The liquid storage chamber 101 and the buffer chamber 201 are connected through a first liquid hole, and the buffer chamber 201 and the atomizing chamber 202 are connected through a second liquid hole 203. The atomizer 100 includes an atomizing component 22 disposed in the atomizing chamber 202. The liquid storage chamber 101 supplies liquid to the buffer chamber 201 through the first liquid hole, and the buffer chamber 201 supplies liquid to the atomizing component 22 through the second liquid hole 203.

[0033] The atomizer 100 can be a one-piece structure, which includes a liquid storage chamber 101, a buffer chamber 201, and an atomization chamber 202. The liquid storage chamber 101 is used to store the aerosol matrix, and the aerosol matrix in the liquid storage chamber 101 is separated from the atomization component 22 by the buffer chamber 201. That is, the liquid aerosol matrix in the atomizer 100 is stored in two chambers, which can effectively reduce the hydraulic pressure or liquid impact force at the atomization component 22, thereby effectively reducing the risk of leakage of the atomizer 100 during transportation and use.

[0034] Analysis revealed that existing atomizers often leak due to excessive hydraulic pressure within the cavity or excessive impact force exerted by the aerosol matrix on the atomizing component 22 and its connections. In this application, the aerosol matrix is ​​stored in separate cavities, and only the buffer cavity 201 directly supplies liquid to the atomizing component 22, while the storage cavity 101 does not directly supply liquid to the atomizing component 22. Therefore, when storing the same capacity of aerosol matrix as existing products, the hydraulic pressure and impact force generated by the buffer cavity 201 on the atomizing component 22 and its connections are greatly reduced, effectively lowering the risk of leakage in the atomizer 100 provided in this application.

[0035] In this embodiment, the atomizer 100 has a split structure. The atomizer 100 includes a detachably connected liquid storage chamber 10 and an atomizing chamber 20. The liquid storage chamber 10 is used to store a large volume of aerosol matrix, and the atomizing chamber 20 is used to temporarily store a small volume of aerosol matrix and can perform atomization treatment on the aerosol matrix.

[0036] The liquid storage chamber 10 has a liquid storage cavity 101 and a liquid passage hole 102 communicating with the liquid storage cavity 101; the atomizing chamber 20 includes an atomizing shell 21 and an atomizing component 22. The atomizing shell 21 is provided with a buffer cavity 201 and an atomizing cavity 202 separated by a partition 210. The atomizing component 22 is installed in the atomizing cavity 202. The partition 210 is provided with a second liquid hole 203. The atomizing shell 21 is provided with a plug-in part 212. The plug-in part 212 is provided with a first liquid hole. The plug-in part 212 is connected to the liquid passage hole 102 to communicate with the liquid storage cavity 101 and the buffer cavity 201. The buffer cavity 201 supplies liquid to the atomizing component 22 through the second liquid hole 203. The diameter of the second liquid hole 203 is larger than the diameter of the first liquid hole.

[0037] The aerosol matrix in the storage chamber 101 flows into the buffer chamber 201 through the first liquid hole in the insertion part 212. The aerosol matrix in the buffer chamber 201 then enters the atomizing component 22 through the second liquid hole 203 and can be heated and atomized by the atomizing component 22. As the atomizing component 22 continuously consumes the aerosol matrix, the aerosol matrix in the buffer chamber 201 gradually decreases, and the storage chamber 101 automatically replenishes it to ensure continuous atomization.

[0038] When the aerosol matrix in the reservoir 101 is depleted, the user can easily disassemble and replace the reservoir 10, for example, by refilling the reservoir 10 with the aerosol matrix or by replacing it with a new reservoir 10, thus enabling quick and convenient use. Moreover, since the reservoir 101 does not contain the atomizing component 22, its replacement cost is lower.

[0039] Specifically, in conjunction with reference Figure 2 and Figure 3 The liquid storage chamber 10 includes a liquid storage shell 11, a vent pipe seat 12, a sealing seat 13, and a fixing cover 14. The vent pipe seat 12 connects to the liquid storage shell 11 and together defines the liquid storage chamber 101. The sealing seat 13 includes a flexible pad 132 and a sealing post 134 disposed on the flexible pad 132. The sealing post 134 is inserted into the liquid passage hole 102 of the vent pipe seat 12. The flexible pad 132 is located on one side of the vent pipe seat 12. The fixing cover 14 covers the open end of the liquid storage shell 11 and covers the flexible pad 132. The insertion part 212 is used to insert into the sealing post 134.

[0040] The liquid storage shell 11 has a suction nozzle 110. The venting tube base 12 includes a venting tube 120 and a base 122. One end of the venting tube 120 is connected to the base 122, and the other end of the venting tube 120 is connected to the suction nozzle 110. The base 122 is sealed to the open end of the liquid storage shell 11. The base 122 is provided with a liquid passage hole 102. The venting tube 120 is connected to the outside atmosphere through the suction nozzle 110. The base 122 is provided with a plug-in cavity 124 that connects to the venting tube 120. The plug-in cavity 124 is used to connect to the atomizing component 22 of the atomizing chamber 20 so that the aerosol generated by the atomizing component 22 can be delivered to the user's mouth through the venting tube 120 and the suction nozzle 110.

[0041] The base 122 may have one, two, three, or four liquid passage holes 102 to improve the liquid supply efficiency and liquid supply balance to the atomizing chamber 20; the number of sealing columns 134 is the same as the number of liquid passage holes 102, and the number of sealing columns 134 is the same as the number of plug-in parts 212, and they can all be adapted; for example, when there are at least two liquid passage holes 102, when outside air enters the buffer chamber 201 during use, the air in the buffer chamber 201 is conducted to the liquid storage chamber 101 through the liquid passage holes 102, so that one liquid passage hole 102 conducts aerosol matrix and the other liquid passage hole 102 conducts air, thereby making the aerosol matrix supply during the atomization process stable and good.

[0042] The sealing seat 13 is made entirely of soft silicone material to ensure excellent sealing performance and prevent leakage of the aerosol matrix. The sealing post 134 fits tightly with the liquid passage 102 to enhance the connection stability and sealing performance with the insertion part 212. A sealing plate 136 is also provided inside the through hole of the sealing post 134. Before being damaged, the sealing plate 136 seals the liquid passage 102, ensuring that the aerosol matrix does not leak during transportation and storage. When the insertion part 212 is inserted into the sealing post 134, the sealing plate 136 is damaged, the liquid passage 102 is unobstructed, and the aerosol matrix in the liquid storage chamber 101 can flow smoothly into the buffer chamber 201.

[0043] In other embodiments, a sealing sheet 136 may be formed directly in the liquid passage 102. For example, if the base 122 itself is made of a flexible material, the sealing seat 13 described above can be omitted.

[0044] The flexible pad 132 makes the connection between the fixed cover 14 and the liquid storage shell 11 tighter and more secure. The flexible pad 132 has a through hole corresponding to the position of the insertion cavity 124 and is used to seal the gap between the insertion cavity 124 and the components on the atomizing chamber 20.

[0045] The fixing cover 14 is connected to the liquid storage shell 11 by a snap-fit ​​structure, and is provided with a first clearance opening corresponding to the liquid passage hole 102 and a second clearance opening corresponding to the insertion cavity 124. The edge of the first clearance opening is connected with a plurality of elastic pieces 142 that flip up into the sealing column 134. When the insertion part 212 is inserted into the sealing column 134, the elastic pieces 142 can open inward in a timely manner and can be hooked to the outer wall of the insertion part 212. Therefore, the elastic pieces 142 can effectively prevent the insertion part 212 from falling off and ensure that the liquid storage chamber 10 and the atomizing chamber 20 are firmly connected.

[0046] The outer wall of the plug part 212 is provided with a boss 213 that matches the elastic piece 142. After the boss 213 passes through the elastic piece 142, the elastic piece 142 rebounds and stops on the platform of the boss 213, which further enhances the connection stability and prevents the atomizing chamber 20 and the liquid storage chamber 10 from accidentally separating during use.

[0047] When the connected atomizing chamber 20 and liquid storage chamber 10 are separated, the structure of the elastic sheet 142 will be destroyed to ensure a smooth separation process.

[0048] Continue reading Figure 2 and Figure 3The atomizing chamber 20 also includes a cavity seat 23, a base 24, and a liquid suction component 25. The cavity seat 23 is installed inside the atomizing housing 21 and connected to the partition 210. The cavity seat 23 and the atomizing housing 21 define a buffer chamber 201. The cavity seat 23 is provided with an inclined surface 230 to guide the aerosol matrix to flow to the second liquid hole 203. The base 24 is connected to the bottom of the atomizing housing 21 and is used to fix the cavity seat 23 in conjunction with the atomizing housing 21. The liquid suction component 25 is installed on the base 24 and is set corresponding to the atomizing assembly 22.

[0049] The atomizing housing 21 includes an outer shell 211, a plug-in portion 212, and a partition 210. The plug-in portion 212 is located at the end of the outer shell 211 facing the liquid storage chamber 10. The partition 210 connects the outer shell 211 and divides the internal space of the outer shell 211 into two spaces, which are respectively used to form a buffer chamber 201 and an atomizing chamber 202. The atomizing chamber 202 formed by the partition 210 has a part located in the outer shell 211 and another part located on the side of the outer shell 211 facing the liquid storage chamber 10. The atomizing component 22 is embedded in the atomizing chamber 202. The structure formed by the partition 210 is also used to insert into the plug-in cavity 124. Therefore, part of the atomizing component 22 can be set outside the outer shell 211, reducing the space occupied inside the outer shell 211. This makes the overall design of the atomizing chamber 20 more compact, reduces space waste, and saves material costs.

[0050] The cavity seat 23 is embedded in the outer shell 21 and has a plug groove that matches the end of the partition 210 to prevent leakage of the buffer cavity 201 defined by the cavity seat 23 and the atomizing shell 21. The plug groove design ensures a tight fit between the cavity seat 23 and the partition 210, improving the sealing and reliability of the overall structure.

[0051] The cavity of the cavity seat 23 is roughly a conical cavity. The insertion groove is located on the bottom surface of the conical cavity. The inclined surface 230 is the side surface of the conical cavity that connects to the bottom surface. The design of the inclined surface 230 allows the aerosol matrix in the buffer cavity 201 to flow smoothly to the second liquid hole 203 under the action of gravity. The second liquid hole 203 is close to the bottom surface of the conical cavity.

[0052] The base 24 is connected to the open end of the atomizing housing 21 and abuts against the bottom of the cavity seat 23 to ensure its stable positioning. The liquid suction component 25 is located between the base 24 and the cavity seat 23, used to absorb condensate generated at the atomizing assembly 22 or leaked liquid from the buffer chamber 201, preventing leakage to the main unit 200 below. The liquid suction component 25 is made of a high-efficiency liquid-absorbing material to ensure that condensate and leaked liquid can be quickly absorbed.

[0053] A conductive electrode is also installed on the base 24. The conductive electrode is electrically connected to the atomizing component 22 and is used to form a closed loop with the circuit system of the main unit 200.

[0054] The base 24 is also equipped with magnetic poles, which cooperate with the magnetic induction element of the main unit 200 to ensure that the atomizer 100 and the main unit 200 are precisely aligned.

[0055] In this application, the diameter of the second liquid hole 203 is larger than the diameter of the first liquid hole on the plug-in portion 212, forming a diameter difference between the two. The relatively larger diameter of the second liquid hole 203 facilitates the rapid flow of the aerosol matrix in the buffer chamber 201 into the atomizing component 22, reducing the risk of the atomizing component 22 clogging due to insufficient liquid supply. The relatively smaller diameter of the first liquid hole on the plug-in portion 212 allows for appropriate control of the liquid supply flow rate into the buffer chamber 201, reducing the risk of leakage due to excessive flow rate or excessive hydraulic pressure, and ensuring a stable and efficient liquid supply process.

[0056] When the atomizing component 22 is operating, the aerosol matrix in the buffer chamber 201 decreases due to continuous atomization by the atomizing component 22, and the aerosol matrix in the liquid storage chamber 101 is replenished to the buffer chamber 201 through the through hole in the insertion part 212. When the aerosol matrix in the liquid storage chamber 101 is consumed to a certain extent, due to the aperture difference between the second liquid hole 203 and the insertion part 212, the air pressure in the buffer chamber 201 may be lower than atmospheric pressure or even form a negative pressure. The low-pressure environment of the buffer chamber 201 can, on the one hand, prompt the liquid storage chamber 101 to supply liquid to it, and on the other hand, promote the passage of outside air through the atomizing component. 22 enters the buffer chamber 201 in an attempt to restore the air pressure balance within the buffer chamber 201, so that outside air can smoothly enter the buffer chamber 201. Of course, outside air can also enter the liquid storage chamber 101 through the insertion part 212. The speed of entering the liquid storage chamber 101 is relatively slower. Therefore, the low-pressure environment of the buffer chamber 201, the liquid supply of the liquid storage chamber 101, and the entry of outside air can ultimately achieve a dynamic balance, thereby maintaining a stable supply of aerosol matrix to the atomizing component 22, ensuring continuous and efficient atomization effect, and effectively preventing leakage from the buffer chamber 201.

[0057] In this application, by setting the aperture difference between the second liquid hole 203 and the first liquid hole on the insertion part 212, a low-pressure environment is cleverly formed in the buffer chamber 201 during the liquid supply process. Then, by utilizing the pressure difference between the low-pressure environment and the external atmospheric pressure, the atomizer 100 provided in this application can ensure smooth liquid supply and prevent leakage, thereby improving the overall performance of the atomizer 100, ensuring a better user experience during use, and clearly feeling the uniformity and persistence of the atomization effect. It also avoids atomization interruption caused by unstable liquid supply, making the equipment operation more stable.

[0058] In this embodiment, the diameter of the second liquid hole 203 is 0.3mm to 3.5mm, and the diameter of the first liquid hole on the insertion part 212 is 0.2mm to 3.0mm. For example, the diameter of the second liquid hole 203 is 0.3mm, and the diameter of the first liquid hole on the insertion part 212 is 0.2mm, with a diameter difference of 0.1mm. This allows for precise control of the liquid flow rate from the liquid storage chamber 10 to the atomizing chamber 20, ensuring efficient operation of the atomizing component 22 while effectively reducing the risk of leakage.

[0059] Optionally, the diameter of the second liquid hole 203 is 0.5 mm, and the diameter of the first liquid hole on the insertion part 212 is 0.3 mm; or, the diameter of the second liquid hole 203 is 1.0 mm, and the diameter of the first liquid hole on the insertion part 212 is 0.6 mm; or, the diameter of the second liquid hole 203 is 2.2 mm, and the diameter of the first liquid hole on the insertion part 212 is 1.5 mm; or, the diameter of the second liquid hole 203 is 3.5 mm, and the diameter of the first liquid hole on the insertion part 212 is 3.0 mm. By using different combinations of hole diameters, the liquid supply speed and air intake balance can be precisely adjusted to ensure that the atomizer 100 can work stably and efficiently in different usage scenarios, and effectively avoid liquid leakage.

[0060] In this embodiment, the volume of the buffer chamber 201 is smaller than the volume of the storage chamber 101, and the volume of the buffer chamber 201 is 0.5 mL to 2.5 mL. The volume of the buffer chamber 201 ensures sufficient contact between the aerosol matrix and the atomizing component 22, and also makes the pressure changes within the buffer chamber 201 more sensitive, thus transmitting the pressure changes to the storage chamber 101, thereby allowing the aerosol matrix in the storage chamber 101 to be promptly guided into the buffer chamber 201.

[0061] Optionally, the volume of the buffer chamber 201 can be 0.5 mL, 0.8 mL, 2.0 mL, 1.5 mL, 2.0 mL or 2.5 mL.

[0062] See also Figure 3 and Figure 4 ,in Figure 4 yes Figure 3 The diagram shows the exploded structure of the atomizing component in the atomizer.

[0063] The atomizing component 22 includes an atomizing core 220 and a liquid storage component 223 sleeved on the outside of the atomizing core 220. The liquid storage component 223 covers the second liquid hole 203 and is used to conduct the aerosol matrix to the atomizing core 220.

[0064] The liquid storage component 223 can be made of materials such as polyester fiber, polypropylene fiber, non-woven fabric or cotton, and has excellent liquid absorption and conduction capabilities. The liquid storage component 223 absorbs liquid from the buffer chamber 201 through the second liquid hole 203 and can stably and smoothly transfer the aerosol matrix to the atomizing core 220.

[0065] The liquid storage component 223 is provided with a perforation 224, and the atomizing core 220 is inserted through the perforation 224 and installed together in the atomizing chamber 202. The liquid storage component 223, the atomizing core 220 and the partition 210 are all tightly fitted. The liquid storage component 223 is also arranged around the atomizing core 220. Therefore, the liquid storage component 223 can effectively wrap the atomizing core 220 and supply liquid evenly.

[0066] The atomizing core 220 has a cylindrical structure and may include a sleeve, a liquid-guiding cotton located inside the sleeve, and a heating element disposed inside the liquid-guiding cotton. The sleeve has through holes on its wall to allow the aerosol matrix to be guided from the liquid storage component 223 to the liquid-guiding cotton and rapidly heated by the heating element. Alternatively, the atomizing core 220 may include a porous substrate and a heating element disposed within the porous substrate. The porous substrate may be made of porous ceramic or porous glass, and the heating element may be a heating film or a heating wire.

[0067] In this embodiment, the liquid storage component 223 is also used to conduct outside air to the second liquid hole 203 so that it enters the buffer cavity 201 through the second liquid hole 203.

[0068] In other words, the second liquid hole 203 has both liquid and air passage functions. When a low-pressure environment is formed in the buffer chamber 201, outside air can be introduced. This allows the low-pressure environment of the buffer chamber 201, the liquid supply of the liquid storage chamber 101, and the entry of outside air to achieve a dynamic balance. This ensures that the aerosol matrix is ​​smoothly transported to the atomizing core 220 and effectively prevents leakage from the buffer chamber 201, thereby ensuring the stability and efficiency of the atomization process.

[0069] The liquid storage component 223 has a columnar structure, which can be elliptical or prismatic, etc. The wall thickness of the liquid storage component 223 in the first direction A is less than the wall thickness in the second direction B. The first direction A is the direction from the atomizing core 220 toward the second liquid hole 203, and the second direction B is perpendicular to the first direction A.

[0070] Here, the wall thickness of the liquid reservoir 223 refers to the wall thickness from the inner wall surface of the perforation 224 along the first direction A or the second direction B to the outer surface of the liquid reservoir 223.

[0071] The liquid storage component 223 has a smaller wall thickness in the first direction A to shorten the liquid guiding path from the second liquid hole 203 to the atomizing core 220, facilitating the rapid introduction of the aerosol matrix into the atomizing core 220 via the second liquid hole 203 and improving the liquid supply efficiency. Simultaneously, the aerosol matrix entering through the second liquid hole 203 is also guided to a portion of the liquid storage component 223 located in the second direction B. The liquid storage component 223 has a larger wall thickness in the second direction B, thus storing more aerosol matrix in a larger area. This enhances the continuous liquid supply capability of the liquid storage component 223 to the atomizing core 220. Even if the aerosol matrix in the liquid storage chamber 101 experiences insufficient liquid supply due to factors such as low air pressure, a stable liquid supply to the atomizing core 220 can be maintained for a period of time, ensuring the continuity and efficiency of the atomization process. This period can also be used to allow air to enter through the second liquid hole 203 to improve the low air pressure within the chamber, thereby ensuring continuous liquid supply during the atomization process.

[0072] The structure of the liquid storage component 223 cleverly combines the balance of liquid guiding, liquid storage and air guiding. By optimizing the wall thickness distribution, it shortens the liquid guiding path and air intake path, and improves the liquid storage capacity, ensuring that the liquid supply can still be maintained when the air pressure fluctuates, effectively ensuring the working stability of the atomizing core 220.

[0073] In this embodiment, the partition plate 210 is provided with two second liquid holes 203 spaced apart along the first direction A, so as to further improve the uniform liquid guiding and gas guiding effect of the second liquid holes 203. The two second liquid holes 203 can better take into account both liquid guiding and gas guiding capabilities.

[0074] Unlike existing technologies, this application discloses an electronic atomizing device and its atomizer. By incorporating a liquid storage chamber and an atomizing chamber within the atomizer, the diameter of the second liquid orifice is larger than the diameter of the orifice in the insertion part. The insertion part connects the atomizing chamber to the liquid storage chamber. The second liquid orifice connects the buffer chamber and the atomizing component. The relatively larger diameter of the second liquid orifice facilitates the rapid flow of the aerosol matrix from the buffer chamber into the atomizing component, reducing the risk of coil clogging due to insufficient liquid supply. The relatively smaller diameter of the orifice in the insertion part allows for appropriate control of the liquid flow rate into the buffer chamber, reducing the risk of leakage due to excessive flow rate or hydraulic pressure, ensuring a stable and efficient liquid supply process. The hole between the second liquid orifice and the insertion part... The diameter difference also allows a low-pressure environment to be formed in the buffer chamber during liquid supply. This low-pressure environment in the buffer chamber can, on the one hand, encourage the liquid storage chamber to supply liquid to it, and on the other hand, it can also promote the entry of outside air into the buffer chamber through the atomizing component in an attempt to restore the air pressure balance in the buffer chamber. Thus, the low-pressure environment in the buffer chamber, the liquid supply in the liquid storage chamber, and the entry of outside air can ultimately achieve a dynamic balance, thereby maintaining a stable supply of aerosol matrix to the atomizing component, ensuring continuous and efficient atomization, and effectively preventing liquid leakage in the buffer chamber, thus ensuring the stability and efficiency of the atomization process.
