[0003] The nebulizer has a liquid storage tank for storing aerosol matrix and an atomizing core for heating and atomizing the aerosol matrix. The liquid storage tank of the existing nebulizer is usually directly connected to the liquid inlet end of the atomizing core. When the liquid storage tank is filled with liquid or the nebulizer is assembled and transported, the pressure inside the liquid storage tank changes, and the aerosol matrix in the liquid storage tank may leak from the atomizing core to the outer surface of the nebulizer, thereby affecting the experience of the nebulizer. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide an atomizer and an electronic atomization device, aiming to solve the problem of leakage of liquid in the liquid storage tank of the existing atomizer because the liquid storage tank is always connected to the atomization core.

[0007] The beneficial effects of the present application are: by controlling the atomizer seat to move between the first position and the second position relative to the shell, the relative position between the liquid storage tank and the liquid inlet is changed; when the atomizer seat is in the second position, the aerosol matrix in the liquid storage tank can flow smoothly into the liquid inlet, the liquid supply of the atomizer is stable, and the user can use it for normal inhalation; when the atomizer seat is in the first position, the liquid inlet is located outside the liquid storage tank, and the atomizer core is isolated from the liquid storage tank, which effectively reduces the leakage of the aerosol matrix in the liquid storage tank. In the first position, it is suitable for filling or transporting the atomizer, thereby improving product stability.

[0008] In some embodiments, the shell assembly includes a base disposed within the outer shell, and the bottom end of the air duct extends out of the atomizer seat and is connected to the base; when the atomizer seat moves from the first position to the second position, the atomizer seat moves toward the base until it is limited and engaged with the base.

[0009] By adopting the above technical solution, the bottom end of the air guide tube is connected to the base, and the air guide tube maintains a stable structure during the movement of the atomizer seat; the atomizer seat is limited and cooperates with the base in the second position, and the base can provide support force for the atomizer seat. In this position, the liquid inlet and the liquid storage tank are stably connected, and the atomizer can work stably to generate atomized gas.

[0010] In some embodiments, the bottom end of the atomizer seat is sleeved on the base, a limiting protrusion is provided on the side wall of the base, and a limiting groove is provided on the side wall of the atomizer seat; when the atomizer seat is in the first position, the bottom end of the atomizer seat is limitedly engaged with the limiting protrusion; when the atomizer seat is in the second position, the limiting protrusion is engaged with the limiting groove.

[0014] In some embodiments, the air guide tube is a hollow tube, and the diameter of the air guide tube at each position in the first direction is equal.

[0015] By adopting the above technical solution, the diameters of the air duct at various locations in the first direction do not differ. When the position between the air duct and the liquid storage tank changes, the volume of the liquid stored in the liquid storage tank does not change, so that no pressure changes occur inside the liquid storage tank, thereby preventing leakage.

[0016] In some embodiments, the atomizer further includes a nozzle assembly disposed at the top of the shell and a seal disposed between the nozzle assembly and the atomizer seat; the nozzle assembly is connected to the atomizer seat; the seal has an air hole connected between the air guide tube and the nozzle assembly, and the air guide tube is inserted into the air hole.

[0018] In some embodiments, the liquid storage tank penetrates the top of the atomizer seat along the first direction, so that a liquid injection port surrounding the air guide tube is formed at the top of the atomizer seat, and the sealing member seals the liquid injection port.

[0019] By adopting the above technical solution, all parts of the cross-section of the atomizer seat except the air guide tube can be injected with liquid, thereby maximizing the injection area, thereby achieving large-caliber injection, reducing the difficulty of injection, and reducing the occurrence of leakage during the injection process.

[0021] By adopting the above technical solution, in the first position, the atomizer core is separated from the liquid storage tank, that is, the core and liquid are separated to prevent leakage, and the atomizer does not generate atomized gas, so the air pipe and the sealing member may not be completely sealed; in the second position, the atomizer core is connected to the liquid storage tank, the atomizer can generate atomized gas, and the air guide tube and the convex ring are interference fit, thereby further improving the sealing between the air guide tube and the sealing member, effectively preventing air and liquid leakage.

[0022] In some embodiments, the protruding ring includes a middle portion and inclined portions formed at opposite ends of the middle portion; the middle portion extends along the first direction.

[0023] By adopting the above technical solution, the cross-section of the convex ring is trapezoidal, and a longer sealing section is provided between the air pipe and the sealing member through the middle portion, which is conducive to improving the sealing performance and reducing leakage.

[0024] In some embodiments, the sealing member is provided with at least one slot on the inner wall surface of the air hole, the bottom end of the slot passes through the sealing member along the first direction; and the top end of the slot is lower than the convex ring.

[0027] By adopting the above technical solution, the limiter has a good contact area with the sealing member through the abutment surface, so that the force is evenly dispersed, and then the limiter can provide better support, preventing the seal from being directly squeezed and contacted with the air duct, causing the air duct to scrape the seal.

[0028] In a second aspect, an embodiment of the present application provides an electronic atomization device, comprising a power supply assembly and the atomizer, wherein the power supply assembly is used to supply power to the atomizer. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Electronic atomization devices are used to atomize a liquid aerosol matrix into atomized gas and are widely used in fields such as e-cigarettes and medical treatments. Atomizers have a liquid reservoir for storing the aerosol matrix and an atomizer core for heating and atomizing the aerosol matrix. Existing atomizers typically have a liquid reservoir directly connected to the liquid inlet of the atomizer core. When the liquid reservoir is filled or during assembly and transportation, pressure changes occur within the reservoir, potentially causing the aerosol matrix in the reservoir to leak from the atomizer core onto the outer surface of the atomizer, affecting the atomizer experience.

[0059] Based on this, in order to solve the above problems, the present application designs an atomizer, which changes the relative position between the liquid storage tank and the liquid inlet by controlling the atomizer seat to move between a first position and a second position relative to the shell; when the atomizer seat is in the second position, the aerosol matrix in the liquid storage tank can flow smoothly into the liquid inlet, the atomizer liquid supply is stable, and can be used for normal inhalation by the user; when the atomizer seat is in the first position, the liquid inlet is located outside the liquid storage tank, and the atomizer core is isolated from the liquid storage tank, effectively reducing the leakage of the aerosol matrix in the liquid storage tank. In this first position, it is suitable for filling or transporting the atomizer, thereby improving product stability.

[0060] Please refer to Figure 2-4 、 Figure 5-Figure 7 , the embodiment of the present application provides a nebulizer 100, comprising a shell assembly 1, an atomizer seat 3 and an air guide tube 2; the shell assembly 1 comprises a shell 101; the atomizer seat 3 is movably arranged in the shell 101, and the atomizer seat 3 has a liquid storage tank 301 for storing aerosol matrix; the air guide tube 2 is arranged in the shell 101, and the air guide tube 2 is passed through the liquid storage tank 301; an atomizer core 4 is arranged in the air guide tube 2, and a liquid inlet 5 is provided on the side wall of the air guide tube 2 to connect the atomizer core 4 with the outside of the air guide tube 2; the atomizer seat 3 can move between a first position and a second position along a first direction X relative to the air guide tube 2; when the atomizer seat 3 is in the first position, the liquid inlet 5 is located outside the liquid storage tank 301; when the atomizer seat 3 is in the second position, the liquid inlet 5 is located inside the liquid storage tank 301 to connect the atomizer core 4 with the liquid storage tank 301.

[0061] As can be understood, the atomizer core 4 is located within the airway tube 2. The aerosol matrix in the liquid reservoir 301 is delivered to the atomizer core 4 through the liquid inlet 5. The atomizer core 4 heats and atomizes the aerosol matrix to generate an aerosol, which then passes through the airway tube 2. The liquid reservoir 301 is used to absorb / store the aerosol matrix. The liquid reservoir 301 can be a cavity, directly storing the aerosol matrix in the liquid reservoir 301; alternatively, a liquid reservoir cotton can be provided within the liquid reservoir 301, onto which the aerosol matrix is ​​absorbed.

[0062] refer to Figure 2 、 Figure 5 The first direction X is the longitudinal direction of the air duct 2, and the first direction X is the X direction in the figure. The air duct 2 is disposed within the housing 101 and passes through the atomizer seat 3. The atomizer seat 3 and the air duct 2 can be relatively displaced in the first direction X, thereby adjusting the position between the liquid inlet 5 and the liquid storage tank 301.

[0063] Specifically, the atomizer seat 3 can move along the first direction X in the housing 101, and the air duct 2 remains fixed; Figure 2-Figure 3 , when the atomizer seat 3 is in the first position, the liquid inlet 5 is located outside the liquid storage tank 301 to be separated from the liquid storage tank 301, and then the atomizer core 4 is separated from the liquid storage tank 301 at this time, and the atomizer core 4 will not come into contact with the liquid aerosol matrix. The liquid storage tank 301 is in an isolated state, which greatly reduces the leakage of the aerosol matrix in the liquid storage tank 301, is conducive to the injection or transportation of the atomizer 100, and improves the stability of the product; Figure 4-Figure 6 When the atomizer seat 3 is in the second position, the liquid storage tank 301 is connected to the liquid inlet 5, the aerosol matrix in the liquid storage tank 301 can flow smoothly from the liquid inlet 5 to the atomizer core 4, the liquid supply is stable, and the atomizer 100 can be used for normal inhalation by the user.

[0064] The atomizer seat 3 and the housing 101 may be connected by sleeve connection, sliding groove connection or other connection methods, so as to ensure that the atomizer seat 3 can move in the first direction X relative to the housing 101 .

[0065] The atomizer 100 of the present application changes the relative position between the liquid storage tank 301 and the liquid inlet 5 by controlling the atomizer seat 3 to move between the first position and the second position; when the atomizer seat 3 is in the second position, the aerosol matrix in the liquid storage tank 301 can flow smoothly into the liquid inlet 5, and the atomizer 100 has a stable liquid supply and can be used for normal inhalation by the user; when the atomizer seat 3 is in the first position, the liquid inlet 5 is located outside the liquid storage tank 301, and the atomizer core 4 is isolated from the liquid storage tank 301; the phenomenon of leakage of the aerosol matrix in the liquid storage tank 301 is effectively reduced. In the first position, it is suitable for filling or transporting the atomizer 100, thereby improving product stability.

[0066] refer to Figure 3 、 Figure 6 、 Figure 8 In some embodiments, the housing assembly 1 includes a base 102 disposed in the outer shell 101, and the bottom end of the air guide tube 2 extends out of the atomizer seat 3 and is connected to the base 102; when the atomizer seat 3 moves from the first position to the second position, the atomizer seat 3 moves toward the base 102 until it is limited and engaged with the base 102.

[0067] Specifically, the bottom end of the air duct 2 extends to the outside of the liquid storage tank 301 and is connected to the base 102. The air duct 2 and the base 102 can be connected by means of, but not limited to, plugging, sleeve connection, and snap connection, so that the air duct 2 maintains a stable structure in the shell 101 and effectively limits the deviation and shaking of the air duct 2 in the shell 101; that is, during the movement of the atomizer seat 3 relative to the air duct 2 between the first position and the second position, the air duct 2 maintains a stable structure.

[0068] The atomizer seat 3 is located above the base 102. When the atomizer seat 3 is in the second position, the base 102 and the atomizer seat 3 are limited and matched. The base 102 can provide support for the atomizer seat 3. The liquid inlet 5 and the liquid storage tank 301 remain stably connected, and the atomizer 100 can work stably to generate atomized gas.

[0069] In some embodiments, reference Figure 8 The bottom end of the atomizer seat 3 is sleeved on the outside of the base 102, and a limiting protrusion 1102 is provided on the side wall of the base 102; a limiting groove 1101 is provided on the side wall of the atomizer seat 3; when the atomizer seat 3 is in the first position, the bottom end of the atomizer seat 3 is limited and matched with the limiting protrusion 1102; when the atomizer seat 3 is in the second position, the limiting protrusion 1102 is clamped with the limiting groove 1101.

[0070] Specifically, when the atomizer seat 3 is in the first position, the bottom end of the atomizer seat 3 abuts against the limiting protrusion 1102, so that the atomizer seat 3 can stay in the first position; by applying a downward force to the atomizer seat 3 to move the atomizer seat 3 from the first position to the second position, when the atomizer seat 3 is in the second position, the limiting protrusion 1102 is engaged in the limiting groove 1101, and then the structure between the atomizer seat 3 and the base 102 remains stable, the liquid inlet 5 and the liquid storage tank 301 remain stably connected, and the atomizer 100 can continuously generate atomized gas.

[0071] refer to Figure 2-Figure 6 In some embodiments, the atomizer seat 3 includes a main body 302 and a support 303 provided at the bottom end of the main body 302 and protruding downward. The support 303 surrounds the air duct 2, and a liquid storage tank 301 is formed inside the main body 302; a sealing ring 6 is provided inside the support 303 at one end near the liquid storage tank 301 and is sleeved on the air duct 2.

[0072] It can be understood that the bottom end of the main body 302 is provided with a through hole (not shown), and the air guide tube 2 is passed through the through hole into the liquid storage tank 301. The bottom end of the air guide tube 2 is connected to the base 102, and then the atomizer seat 3 can move smoothly relative to the air guide tube 2 along the first direction X, thereby adjusting the relative position between the liquid inlet 5 and the liquid storage tank 301.

[0073] The support 303 is provided with a sealing ring 6 surrounding and covering the air guide tube 2, Figure 4 、 Figure 7 When the atomizer seat 3 is in the first position or the second position, the sealing ring 6 can form an effective seal on the bottom of the liquid storage bin 301 to prevent leakage and improve product stability.

[0074] refer to Figure 3 、 Figure 6 、 Figure 11 、 Figure 12 In some embodiments, the air duct 2 is a hollow tube, and the diameter of the air duct 2 at each position in the first direction X is equal.

[0075] Specifically, during the movement of the atomizer seat 3 between the first position and the second position, the relative position between the air duct 2 and the atomizer seat 3 changes in the first direction X, that is, the air duct 2 moves up and down relative to the liquid storage tank 301. It can be understood that the air duct 2 is disposed within the liquid storage tank 301, and the volume occupied by the air duct 2 within the liquid storage tank 301 will directly affect the volume of liquid stored in the liquid storage tank 301. Since the diameter of the air duct 2 at various locations along the first direction X is the same, and the ends of the air duct 2 cross the ends of the liquid storage tank 301 in both the first and second positions of the atomizer seat 3, the volume occupied by the air duct 2 within the liquid storage tank 301 does not change during the movement of the atomizer seat 3 in the first direction X, and the volume of liquid stored in the liquid storage tank 301 does not change, effectively reducing the pressure fluctuation within the liquid storage tank 301 and the occurrence of liquid leakage.

[0076] refer to Figure 1-Figure 3 、 Figure 5 、 Figure 10 、 Figure 11 In some embodiments, the atomizer 100 further includes a nozzle assembly 7 disposed at the top of the housing 101 and a seal 8 disposed between the nozzle assembly 7 and the atomizer seat 3; the nozzle assembly 7 is connected to the atomizer seat 3; the seal 8 has an air hole 801 connected between the air guide tube 2 and the nozzle assembly 7, and the air guide tube 2 is inserted into the air hole 801.

[0077] It can be understood that the nozzle assembly 7 is formed with a nozzle airway 701, and the nozzle assembly 7 is connected to the atomizer seat 3. The aerosol generated in the air guide tube 2 can smoothly pass through the nozzle airway 701 for inhalation by the user.

[0078] The nozzle assembly 7 and the atomizer seat 3 can be connected by a limited connection method such as a snap connection, a sleeve connection, or a plug connection, so that the nozzle assembly 7 and the atomizer seat 3 can move synchronously along the first direction X. Then, the user can directly hold the nozzle assembly 7 and move it along the first direction X to control the atomizer seat 3 to move between the first position and the second position, which is very easy to operate.

[0079] refer to Figure 1 、 Figure 2 、 Figure 5 In some embodiments, the bottom end of the nozzle assembly 7 is sleeved on the outside of the atomizer seat 3, and the nozzle assembly 7 and the atomizer seat 3 are locked and limited, and the two are firmly connected; the bottom end of the nozzle assembly 7 is sleeved on the inside of the shell 101, and when the atomizer seat 3 moves along the first direction X, the nozzle assembly 7 can perform telescopic movement relative to the shell 101.

[0080] The air guide tube 2 is inserted into the air hole 801 , and the sealing member 8 forms an effective seal between the nozzle assembly 7 and the atomizer seat 3 , effectively preventing air leakage during the gas circulation process.

[0081] refer to Figure 10 In some embodiments, the liquid storage tank 301 penetrates the top of the atomizer seat 3 along the first direction X, so that a liquid injection port 9 surrounding the air guide tube 2 is formed at the top of the atomizer seat 3, and the sealing member 8 seals the liquid injection port 9.

[0082] Specifically, the liquid storage tank 301 passes through the top of the atomizer seat 3, and the liquid filling port 9 is formed between the top of the atomizer seat 3 and the air guide tube 2. Then, the nozzle assembly 7 and the seal 8 only need to be removed from the top of the shell 101, and the liquid storage tank 301 can be filled with liquid through the liquid filling port 9.

[0083] It can be understood that the liquid storage tank 301 extends along the first direction and penetrates the top of the atomizer seat 3, so that the cross-sectional area of ​​the top of the atomizer seat 3, except for the air guide tube 2, can be filled with liquid, thereby maximizing the injection area, thereby achieving large-caliber liquid injection, reducing the difficulty of liquid injection, and reducing the occurrence of liquid leakage during the injection process. Preferably, the air guide tube 2 is located at the center of the liquid storage tank 301, which is more conducive to filling the liquid injection port 9.

[0084] refer to Figure 3 、 Figure 6 、 Figure 11 、 Figure 12 In some embodiments, the sealing member 8 is provided with a convex ring 12 on the inner wall surface of the air hole 801; when the atomizer seat 3 is in the first position, the air guide tube 2 and the convex ring 12 are separated in the first direction X; when the atomizer seat 3 is in the second position, the air guide tube 2 and the convex ring 12 are interference fit.

[0085] Understandably, reference Figure 3 、 Figure 11When the atomizer seat 3 is in the first position, the atomizer core 4 is separated from the liquid storage tank 301, that is, the core and liquid are separated to prevent leakage. At this time, the atomizer 100 is in a non-working state, and no atomized gas is generated in the air guide tube 2. Therefore, the air guide tube 2 and the sealing member 8 do not need to be completely sealed, and the air guide tube 2 can be inserted into the air hole 801 of the sealing member 8.

[0086] refer to Figure 6 、 Figure 12 、 Figure 13 By applying a downward force to the nozzle assembly 7, the atomizer seat 3 is driven downward from the first position relative to the housing 101 to the second position. The liquid reservoir 301 is connected to the atomizer core 4. At this point, the atomizer 100 can function normally, and the atomizer core 4 can generate atomized gas within the airway tube 2. In this second position, the nozzle assembly 7 moves downward relative to the airway tube 2 to create an interference fit between the airway tube 2 and the raised ring 12, further improving the seal between the airway tube 2 and the sealing member 8, effectively preventing air and liquid leakage.

[0087] refer to Figure 13 In some embodiments, the protruding ring 12 includes a middle portion 1201 and inclined portions 1202 formed at opposite ends of the middle portion 1201 , and the middle portion 1201 extends along the first direction X.

[0088] Specifically, the length of the middle portion 1201 aligns with the length of the air hole 801. Once the airway tube 2 is inserted into the air hole 801 and forms an interference fit with the protruding ring 12, the middle portion 1201 will be in close contact with the airway tube 2. Compared to the arc-shaped protruding ring structure of the prior art, the protruding ring 12 of the present application has a trapezoidal cross-section. The middle portion 1201 ensures a greater contact length between the protruding ring 12 and the airway tube 2, improving sealing and reducing leakage.

[0089] The inclined portions 1202 are chamfers or rounded corners formed at opposite ends of the middle portion 1201 , which facilitate the air duct 2 to pass smoothly through the annular protrusion 8 and prevent the air duct 2 from scraping the sealing member 8 .

[0090] refer to Figure 10 、 Figure 13 In some embodiments, the seal 8 has at least one groove 13 on the inner wall surface of the air hole 801 , and the bottom end of the groove 13 passes through the seal 8 along the first direction X; and the top end of the groove 13 is lower than the convex ring 12 .

[0091] It can be understood that during the process of sealing the sealing member 8 and sealing the liquid filling port 9, the sealing member 8 covers the liquid filling port 9, and the air guide tube 2 is inserted upward into the air hole 801. By providing the groove 13 on the inner wall surface of the air hole 801 of the sealing member 8, when the user completes the process of filling the liquid reservoir 301 with liquid and then covers the sealing member 8, although the sealing member 8 has a compression stroke that presses the liquid reservoir 301 downward, because the bottom end of the groove 13 penetrates the sealing member 8 downward, even if the air guide tube 2 is inserted into the air hole 801, the gas in the liquid reservoir 301 can still be discharged to the outside through the groove 13, thereby reducing the pressure change in the liquid reservoir 301 and preventing the occurrence of leakage.

[0092] It is understandable that the shape of the slot 13 can be, but is not limited to, a strip, an arc, or a curve, so that the gas in the liquid storage tank 301 can pass through the slot 13. The number of the slots 13 can also be one or more, which is not specifically limited here.

[0093] Specifically, the groove 13 is arranged between the convex ring 12 and the plug-in end 601, so that before the seal 8 and the air duct 2 form a complete seal, the gas in the liquid storage tank 301 can still be discharged through the groove 13; then, during the process of connecting the seal 8 with the main shell 101, before the seal 8 and the air duct 2 form a complete seal, the excess air in the liquid storage tank 301 will be discharged through the groove 13, reducing the pressure change in the liquid storage tank 301 and preventing leakage.

[0094] refer to Figures 9-12 In some embodiments, the nebulizer 100 further includes a limiting member 10 disposed at the top end of the air guide tube 2, and the top end of the limiting member 10 has a contact surface 1001 for contacting the sealing member 8; the limiting member 10 has a through hole 1002 extending along the first direction X.

[0095] Specifically, the stopper 10 is disposed at the top end of the air duct 2. During insertion of the air duct 2 into the seal 8, the stopper 10 prevents the top end of the air duct 2 from being pressed into contact with the seal 8. Due to the thin wall of the air duct 2, direct pressing contact between the top end of the air duct 2 and the seal 8 could easily damage the seal 8, or the air duct 2 could be inserted into the seal 8, damaging the structure of the seal 8. The top end of the stopper 10 has an abutment surface 1001. When the stopper 10 and the seal 8 come into contact with each other, the abutment surface 1001 provides a good contact area between the stopper 10 and the seal 8, evenly distributing the force. Consequently, the stopper 10 can effectively improve structural stability.

[0096] refer to Figure 9 、 Figure 10 In some embodiments, the outer edge of the top of the limiting member 10 is provided with a rounded corner, so that the outer edge of the top of the limiting member 10 is rounded, further improving the contact safety.

[0097] refer to Figure 11 、 Figure 12 The limiting member 10 has a through hole 1002 that penetrates the gas guide tube 2 and does not affect the gas flowability between the gas hole 801 of the sealing member 8.

[0098] refer to Figure 1-Figure 3 The present application also provides an electronic atomization device 200, comprising a power supply assembly and the above-mentioned atomizer 100, wherein the power supply assembly is used to supply power to the atomizer 100.

[0099] It can be understood that the atomizer 100 is specifically applied to the electronic atomization device 200 , and the power supply component includes a battery 201 electrically connected to the atomization core 4 , and the atomization core 4 is powered by the battery 201 .

[0100] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
