An atomizing device

Abstract

The application discloses an atomizing device, which comprises an oil tank assembly, an atomizing core assembly, a push rod assembly and a fixed sealing piece. The oil tank assembly is internally provided with a main oil storage tank and a vice oil storage tank in communication. The vice oil storage tank is communicated with the atomizing core assembly. The push rod assembly is slidably assembled along the axial direction of the oil tank assembly. The fixed sealing piece is arranged below the vice oil storage tank. When the push rod assembly slides downward to a preset position, the first sealing piece on the outer side of the push rod assembly is in contact with the fixed sealing piece, thereby closing the leakage gap at the lower end of the vice oil storage tank and synchronously ejecting the atomizing core assembly. The existing replaceable core atomizing device is prone to the problem of liquid leakage at the bottom gap when the atomizing core is replaced in the full liquid state, thereby causing oil waste, equipment pollution and even circuit damage. The atomizing device of the application realizes the replacement of the atomizing core without leakage in the full liquid state by means of the push rod linkage sealing structure, which blocks the leakage passage in advance before the atomizing core is ejected, so that the atomizing core can be replaced without pre-evacuating the oil tank liquid, thereby reducing the oil loss, improving the use cleanliness and safety and optimizing the atomizing core replacement operation.

Description

Technical Field

[0001] This invention relates to the field of electronic atomization equipment technology, and in particular to an atomization device. Background Technology

[0002] In the current electronic atomization device market, replaceable coil atomizers have become the mainstream product due to their lower operating costs and flexible consumable replacement. Conventional atomizers of this type typically feature a separate, sealed oil reservoir to store liquid atomizer fluid. This reservoir continuously supplies fluid to the coil chamber below via a fixed wicking channel, ensuring a stable supply of e-liquid to the coil. However, this existing design has an unavoidable flaw in practical use: when the coil is fully filled with fluid (a large amount of residual fluid) and the user needs to replace a worn-out coil, the wicking channel between the reservoir and the coil chamber remains completely open. Without a temporary isolation structure to block the oil path, during the process of disassembling and removing the old atomizer coil, the atomizing liquid inside the oil reservoir will continuously flow outward along the open oil guide channel. This not only causes a large amount of unused atomizing liquid to be directly wasted, but the leaked atomizing liquid will also contaminate the internal electrodes and circuit structure of the device, causing short circuits. At the same time, the leaked atomizing liquid will also contaminate the user's hands and surrounding items, making cleaning very cumbersome. The existing coil replacement atomizer structures in the industry cannot temporarily cut off the oil supply path to the atomizer side of the oil reservoir without damaging the overall oil reservoir sealing structure during the coil replacement operation. This problem has always limited the user experience of replacing atomizer coils when the liquid level is full. Summary of the Invention

[0003] The embodiments of the present invention provide an atomizing device that solves the technical problem that the atomizing liquid in the oil storage chamber is prone to leakage when the atomizing coil is replaced when the existing replaceable atomizing coil electronic atomizing structure is full.

[0004] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides an atomizing device, including an oil tank assembly, an atomizing core assembly, a push rod assembly, and a fixing seal. The oil tank assembly has a main oil storage tank and a secondary oil storage tank that communicate with each other. The secondary oil storage tank is connected to the atomizing core assembly. The push rod assembly is slidably mounted along the axial direction of the oil tank assembly. The fixing seal is disposed below the secondary oil storage tank. When the push rod assembly slides downward to a preset position, a first seal disposed on the outside of the push rod assembly can contact the fixing seal to seal the leakage gap between the lower end of the secondary oil storage tank and the atomizing core assembly, and simultaneously push out the atomizing core assembly.

[0005] Furthermore, the push rod assembly includes a push rod base, a connecting pipe, and a sealing mounting sleeve. The connecting pipe is fixedly sleeved on the outside of the push rod base, the sealing mounting sleeve is integrally formed on the lower end of the push rod base, the first sealing element is assembled on the outer wall of the sealing mounting sleeve, and the connecting pipe is slidably fitted with the inner wall of the oil tank assembly.

[0006] Furthermore, the first sealing element is an annular sealing ring, and an annular groove is provided on the outer wall of the sealing mounting sleeve. The annular sealing ring is fitted into the annular groove. The annular sealing ring can move axially with the push rod assembly. When the push rod assembly moves down to a preset position, the annular sealing ring and the fixed sealing element form an end face seal.

[0007] Furthermore, the push rod assembly has a first limiting position and a second limiting position relative to the oil tank assembly; when the push rod assembly is in the first limiting position, the first seal and the fixed seal are separated from each other, and the auxiliary oil tank can supply oil to the atomizing core assembly; when the push rod assembly is in the second limiting position, the first seal and the fixed seal are fitted together and sealed, and the push rod assembly can push out the atomizing core assembly.

[0008] Furthermore, the atomizing device also includes an air regulating ring, which is mounted on the upper end of the oil tank assembly and is rotatable around an axis.

[0009] Furthermore, the push rod assembly is provided with a limiting boss, the air regulating ring has an air regulating ring inlet and a notch, and the oil tank assembly has an oil tank inlet that matches the air regulating ring inlet. When the air regulating ring rotates to the first angle, the inner wall of the air regulating ring engages with the limiting boss to restrict the push rod assembly from sliding downward. When the air regulating ring rotates to the second angle, the notch matches the limiting boss, and the push rod assembly can slide downward axially. The overlapping area of ​​the air regulating ring inlet and the oil tank inlet can change the air intake volume.

[0010] Furthermore, a second seal is provided between the connection position of the gas regulating ring and the push rod base, and the second seal is used to seal the assembly gap between the gas regulating ring and the push rod base.

[0011] Furthermore, the side wall of the atomizing core assembly is provided with a liquid inlet groove, which connects the interior of the auxiliary oil storage tank with the atomizing core of the atomizing core assembly; in the assembled state of the atomizing core assembly, the liquid inlet groove and the inner side of the fixed seal form an annular leakage gap.

[0012] Furthermore, the sidewall of the oil tank assembly is equipped with an oil injection assembly, which is used to inject atomizing liquid into the main oil storage tank.

[0013] Furthermore, a fixing component is assembled at the bottom of the oil tank assembly. The fixing component includes a positioning bracket and a magnetic suction component. The positioning bracket is fixed at the bottom of the oil tank assembly, the magnetic suction component is embedded inside the positioning bracket, and the fixing seal is fixedly assembled on the inner side of the positioning bracket and corresponds to the lower end position of the auxiliary oil storage tank.

[0014] Compared with the prior art, the atomizing device of the present invention has at least the following beneficial effects: The atomizing device provided by this invention includes an oil tank assembly, an atomizing core assembly, a push rod assembly, and a fixing seal. The oil tank assembly has a main oil storage tank and a secondary oil storage tank that are connected internally. The secondary oil storage tank is connected to the atomizing core assembly. The push rod assembly is slidably mounted along the axial direction of the oil tank assembly. The fixing seal is located below the secondary oil storage tank. When the push rod assembly slides downward to a preset position, a first seal located on the outside of the push rod assembly can contact the fixing seal to seal the leakage gap between the lower end of the secondary oil storage tank and the atomizing core assembly, and simultaneously push out the atomizing core assembly. In existing electronic atomizing structures with replaceable atomizing cores, when the atomizing core is disassembled and replaced while the oil tank is full of atomizing liquid, an open gap appears at the bottom of the oil storage chamber during the process of the atomizing core detaching from the sealed position. The atomizing liquid in the chamber will quickly leak outward along the gap, which not only wastes the atomizing liquid, but the leaked liquid can also corrode the internal circuitry and contaminate the outer casing. This invention uses the downward pressing action of the push rod assembly to first seal the leakage channel at the bottom of the oil storage chamber by fitting the first sealing element and the fixed sealing element together, and then simultaneously pushes out the atomizing core. The oil passage is sealed before the atomizing core is removed from the assembly position, which fundamentally avoids the problem of leakage of atomizing liquid under the condition of full liquid core replacement. There is no need to empty the liquid in the oil tank in advance, which greatly optimizes the atomizing core replacement process.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This embodiment provides an atomizing device, such as Figures 1-8 As shown, the assembly includes an oil tank assembly 1, an atomizer core assembly 2, a push rod assembly 3, and a fixing seal 4. The oil tank assembly 1 has a main oil storage tank 11 and a secondary oil storage tank 12 that are connected to each other. The secondary oil storage tank 12 is connected to the atomizer core assembly 2. The push rod assembly 3 is slidably assembled along the axial direction of the oil tank assembly 1. The fixing seal 4 is located below the secondary oil storage tank 12. When the push rod assembly 3 slides down to a preset position, the first seal 31 located on the outside of the push rod assembly 3 can contact the fixing seal 4 to seal the leakage gap between the lower end of the secondary oil storage tank 12 and the atomizer core assembly 2, and simultaneously push out the atomizer core assembly 2.

[0023] The oil tank assembly 1 is the main supporting shell of this device. Its internal cavity is divided into a main oil storage tank 11 and a secondary oil storage tank 12, which are interconnected. The main oil storage tank 11 serves as a large-capacity storage chamber to hold the majority of the atomizing liquid. The secondary oil storage tank 12 is adjacent to the atomizer core assembly 2 and serves to buffer and store oil, directly supplying oil to the atomizer core. The atomizer core assembly 2 is vertically mounted at the bottom center of the oil tank assembly 1, and is connected to the internal oil passage of the secondary oil storage tank 12. The push rod assembly 3 passes through the center of the oil tank assembly 1 and slides vertically along the central axis of the oil tank assembly 1. The sliding trajectory is constrained by the inner wall of the oil tank and will not deviate radially. The fixed seal 4 is fixedly embedded in the bottom opening of the secondary oil storage tank 12 and surrounds the outside of the atomizer core assembly 2, forming an annular sealing reference surface. The first seal 31 is fixedly mounted on the lower outer wall of the push rod assembly 3 and will move up and down with the push rod assembly 3. When the push rod assembly 3 is pressed down to the preset end point of the stroke, the lower end face of the first seal 31 presses tightly against the fixed seal 4, completely sealing the original annular leakage gap between the two. At the same time, the bottom end face of the push rod assembly 3 presses down against the top of the atomizing core assembly 2, and pushes the atomizing core assembly 2 out from the bottom assembly position by axial thrust.

[0024] In existing electronic atomizing structures with replaceable atomizer coils, when the coil is removed and replaced while the tank is full of atomizer fluid, an open gap appears at the bottom of the tank as the coil detaches from its sealed position. This allows the atomizer fluid to leak rapidly outwards, wasting fluid and potentially corroding internal circuitry and contaminating the casing. This embodiment addresses this by using the downward pressure of the push rod assembly 3 to first seal the leakage channel at the bottom of the tank using the first seal 31 and the fixed seal 4, then simultaneously pushing the coil out. This seals the oil passage before the coil leaves its assembly position, fundamentally preventing leakage during full-fill replacement. It also eliminates the need to empty the tank beforehand, significantly optimizing the coil replacement process.

[0025] In a specific embodiment, the push rod assembly 3 includes a push rod base 32, a connecting pipe 33, and a sealing mounting sleeve 34. The connecting pipe 33 is fixedly sleeved on the outside of the push rod base 32, and the sealing mounting sleeve 34 is integrally formed on the lower end of the push rod base 32. The first sealing element 31 is assembled on the outer wall of the sealing mounting sleeve 34, and the connecting pipe 33 slides with the inner wall of the oil tank assembly 1 to form an axial sliding pair.

[0026] The push rod base 32 is the core load-bearing transmission rod of the push rod assembly 3. It is a hollow tubular structure with an airflow channel running vertically through it. The connecting pipe 33 is tightly fitted onto the middle section of the outer wall of the push rod base 32 using an interference fit. The two fit tightly without relative rotation or axial sliding. The outer surface of the connecting pipe 33 is clearance-fitted with the inner wall of the oil tank assembly 1. The two work together to form an axial sliding pair, restricting the push rod assembly 3 to reciprocate along the vertical axis and preventing tilting during sliding. The sealing mounting sleeve 34 and the push rod base 32 are integrally injection molded, forming an inseparable whole structure that eliminates the risk of oil leakage caused by splicing gaps. The sealing mounting sleeve 34 is located at the bottom of the push rod base 32 and is a dedicated mounting base for the first seal 31. The first seal 31 is assembled on the outer wall of the sealing mounting sleeve 34 and can move up and down synchronously with the entire push rod assembly, ensuring precise alignment with the fixed seal 4 for sealing during each press.

[0027] Specifically, the first sealing element 31 is an annular sealing ring, and the outer wall of the sealing mounting sleeve 34 is provided with an annular groove. The annular sealing ring is fitted into the annular groove. The annular sealing ring can move axially with the push rod assembly 3. When the push rod assembly 3 moves down to the preset position, the annular sealing ring and the fixed sealing element 4 form an end face seal.

[0028] The first sealing element 31 is a rubber annular sealing ring, suitable for long-term immersion of the atomizing liquid in such environments. A concave annular groove is formed around the outer periphery of the sealing mounting sleeve 34. The cross-sectional shape and size of the groove match the cross-section of the annular sealing ring. The annular sealing ring is completely embedded and contained within the groove, preventing circumferential flipping or axial detachment during push rod sliding, and also preventing excessive deformation failure due to compression. The annular sealing ring is completely fixed within the groove, maintaining perfectly synchronized axial displacement with the push rod assembly 3, with identical displacement stroke and start / stop times. When the push rod assembly 3 slides downwards to the preset limit position, the outer end of the annular sealing ring presses against the annular plane of the fixed sealing element 4. The rubber's own elastic deformation fills the tiny gap between the two end faces, forming a sealed end-face sealing structure, completely isolating the downward leakage path of the auxiliary oil reservoir 12.

[0029] In a specific embodiment, the push rod assembly 3 has a first limiting position and a second limiting position relative to the oil tank assembly 1; when the push rod assembly 3 is in the first limiting position, the first sealing member 31 and the fixed sealing member 4 are separated from each other, and the auxiliary oil storage tank 12 can supply oil to the atomizing core assembly 2; when the push rod assembly 3 is in the second limiting position, the first sealing member 31 and the fixed sealing member 4 are fitted and sealed, and the push rod assembly 3 can push out the atomizing core assembly 2.

[0030] The push rod assembly 3 is structurally limited to two extreme working positions within the oil tank assembly 1: the high position is the first limit position, and the low position is the second limit position. When the push rod assembly is in the first limit position, as... Figure 1 As shown, the entire unit is in a raised state. The first seal 31 follows the sealing mounting sleeve 34 away from the fixed seal 4 below, leaving sufficient flow space between the two sealing components. The bottom opening of the auxiliary oil storage tank 12 is fully open, allowing the atomizing liquid to flow smoothly to the atomizing core assembly 2, maintaining normal atomization and oil supply conditions. When the push rod assembly is manually pressed downwards, causing it to overcome the resistance of the limiting structure and descend to the second limiting position, as... Figure 3 and Figure 4 As shown, when the push rod reaches the end of its stroke and cannot move further, the first seal 31 tightly adheres to the surface of the fixed seal 4, completing the locking seal. At the same time, the bottom of the push rod assembly 3 extends to its limit position, just abutting against the atomizer core assembly 2, causing it to detach from the installation position. The two limit positions have clear functions: one corresponds to the normal working mode, and the other corresponds to the core replacement sealing mode. The position switching is simple and reliable.

[0031] In one embodiment, the atomizing device further includes an air regulating ring 5, which is mounted on the upper end of the oil tank assembly 1 and is rotatable around an axis. The air regulating ring 5 is a ring-shaped structural component that is rotatably fitted onto the upper end of the oil tank assembly 1. The entire ring is axially limited by the stepped structure at the upper end of the oil tank assembly, and can only rotate around the central axis of the device, without falling off vertically or moving axially.

[0032] Specifically, the push rod assembly 3 is provided with a limiting boss 35, the air regulating ring 5 has an air regulating ring inlet hole 51 and a notch 52, and the oil tank assembly 1 has an oil tank inlet hole 13 that matches the air regulating ring inlet hole 51. When the air regulating ring 5 rotates to the first angle, the inner wall of the air regulating ring 5 cooperates with the limiting boss 35 to restrict the push rod assembly 3 from sliding downward. When the air regulating ring 5 rotates to the second angle, the notch 52 matches the limiting boss 35, and the push rod assembly 3 can slide downward axially. The overlapping area of ​​the air regulating ring inlet hole 51 and the oil tank inlet hole 13 can change the air intake.

[0033] The limiting boss 35 is integrally formed on the upper outer wall of the push rod assembly 3, protruding radially outward, and moves up and down synchronously with the push rod assembly 3. The side wall of the air regulating ring 5 is respectively provided with a through air regulating ring inlet hole 51 and a hollow notch 52. The upper side wall of the oil tank assembly 1 is provided with an oil tank inlet hole 13. The opening position and diameter of the oil tank inlet hole 13 are adapted to the air regulating ring inlet hole 51. The overlapping area of ​​the two is the air intake channel.

[0034] When the air regulating ring 5 rotates to the first angle, the solid inner wall of the air regulating ring 5 without the notch is exactly on the downward movement path of the limiting boss 35, which will form a hard resistance to the limiting boss 35, thereby restricting the downward sliding of the entire push rod assembly and playing a protective effect against accidental contact and pressing. At this time, the overlapping area of ​​the air inlet 51 of the air regulating ring and the air inlet 13 of the oil tank changes synchronously, which can reduce the air intake or even completely close the air intake. When the air regulating ring 5 continues to rotate to the second angle, the notch 52 on the air regulating ring 5 is aligned with the limiting boss 35. The limiting boss 35 can be aligned and passes through the notch 52, and is no longer blocked by the inner wall of the air regulating ring. The push rod assembly unlocks the restriction on axial displacement. At this time, pressing the mouthpiece 8 can drive the push rod assembly 3 to move downward, completing the action of sealing the oil circuit and pushing out the atomizing core. At the same time, by relying on the change of the overlapping area of ​​the two air inlets, the air intake volume can be adjusted as needed to adapt to different atomization needs.

[0035] In a specific embodiment, a second sealing element 53 is provided between the connection position of the gas regulating ring 5 and the push rod base 32. The second sealing element 53 is used to seal the assembly gap between the gas regulating ring 5 and the push rod base 32.

[0036] The second sealing element 53 is an annular static sealing gasket, sandwiched between the inner top surface of the air regulating ring 5 and the upper stepped surface of the push rod base 32. It is clamped and fixed by the two components and will not rotate with the air regulating ring or move up and down with the push rod assembly 3. The inner and outer diameters of the second sealing element 53 are respectively fitted to the outer wall of the push rod base 32 and the inner wall of the air regulating ring 5, completely filling the annular gap created by their assembly. During the suction atomization process, it prevents the airflow from leaking out from the top assembly gap, ensuring that all the intake airflow enters the device from the preset air inlet, stabilizing the internal air pressure of the cavity, preventing air pressure imbalance from squeezing the atomized liquid inside the oil tank and causing leakage, while ensuring a stable atomized airflow concentration.

[0037] In a specific embodiment, such as Figure 8 As shown, the side wall of the atomizing core assembly 2 is provided with a liquid inlet groove 21, which connects the interior of the auxiliary oil storage tank 12 with the atomizing core of the atomizing core assembly 2; in the assembled state, the liquid inlet groove 21 and the inner side of the fixed seal 4 form an annular leakage gap.

[0038] The liquid inlet channel 21 is vertically formed on the outer circular surface of the side wall of the atomizing core assembly 2. The upper end of the channel connects to the oil storage space of the auxiliary oil storage tank 12, and the lower end extends to the position of the atomizing core inside the atomizing core assembly 2. It serves as a dedicated channel for transporting atomizing liquid, allowing the atomizing liquid in the auxiliary oil storage tank 12 to continuously wet the atomizing core. When the atomizing core assembly 2 is fully assembled, the outer wall of the atomizing core, the lower edge of the liquid inlet channel, and the inner ring wall of the fixing seal 4 form an annular leakage gap. This gap is the inevitable channel for atomizing liquid leakage in the prior art. Before the push rod assembly 3 is pressed down to seal, the atomizing liquid will flow outward along this gap. In this embodiment, the first seal 31 is pressed down to tighten the fixing seal 4, sealing the annular leakage gap and blocking the leakage channel from the source.

[0039] In one embodiment, the sidewall of the oil tank assembly 1 is equipped with an oil injection assembly 6, which is used to inject atomizing liquid into the main oil storage tank 11 and the auxiliary oil storage tank 12.

[0040] The oil filling assembly 6 is sealed and assembled on the outer wall of the oil tank assembly 1. Its opening is directly opposite the cavity of the main oil tank 11 or the auxiliary oil tank 12, serving as the sole atomizing liquid filling port for the entire device. It employs a plug or screw cap structure for opening and closing. After opening the oil filling assembly 6, the atomizing liquid can be directly poured into the larger main oil tank 11. Relying on the pre-set connecting channel between the main oil tank 11 and the auxiliary oil tank 12, the atomizing liquid flows into the auxiliary oil tank 12 by gravity to complete the replenishment, eliminating the need for separate oil filling of the two tanks. Closing the oil filling assembly 6 completely seals the filling port, preventing atomizing liquid evaporation and loss, while also preventing external dust and moisture from entering the oil tank and contaminating the atomizing liquid, ensuring the cleanliness of the supplied oil.

[0041] In one embodiment, the bottom of the oil tank assembly 1 is equipped with a fixing component 7. The fixing component 7 includes a positioning bracket 71 and a magnetic suction component 72. The positioning bracket 71 is fixed to the bottom of the oil tank assembly 1, the magnetic suction component 72 is embedded inside the positioning bracket 71, and the fixing seal 4 is fixedly assembled to the inner side of the positioning bracket 71 and corresponds to the lower end position of the auxiliary oil storage tank 12.

[0042] The positioning bracket 71 is locked and fixed to the bottom of the oil tank assembly 1 by snap-fit ​​or threaded fastening, serving as the load-bearing base for the entire bottom structure and providing a positioning reference for other parts. The magnetic component 72 is embedded in the pre-reserved slot inside the positioning bracket 71 by injection molding or press-fitting, relying on magnetic attraction to achieve quick alignment and adsorption assembly of the whole unit and the battery host, making disassembly and assembly convenient. The fixing seal 4 is press-fitted into the center inner ring of the positioning bracket 71, with precise vertical alignment to the bottom opening of the auxiliary oil tank 12. The position will not loosen or shift, and it can work stably with the first seal 31 for a long time to complete the end face seal, continuously ensuring the anti-leakage effect during the core replacement process.

[0043] In normal atomization operation, the push rod assembly 3 is in the first limit position, the first seal 31 is separated from the fixed seal 4, and the annular leakage gap at the lower end of the auxiliary oil tank 12 remains open. The atomizing liquid inside the main oil tank 11 is continuously replenished to the auxiliary oil tank 12 by gravity. The atomizing liquid in the auxiliary oil tank 12 continuously wets the atomizing core body through the liquid inlet groove 21 on the side wall of the atomizing core assembly 2, ensuring continuous oil supply and atomization. At this time, the air intake flow can be freely adjusted by rotating the air regulating ring 5 to change the overlapping area between the air intake hole 51 of the air regulating ring and the air intake hole of the oil tank, adapting to different atomization flavors. The air regulating ring 5 can be rotated to the locked or unlocked position according to usage needs. In daily use, it can be switched to the locked position to prevent accidental pressure.

[0044] Air regulating ring locking anti-accidental contact operation: Rotate the air regulating ring 5 to the first angle, so that the solid inner wall area of ​​the air regulating ring 5 is aligned with the downward path of the limiting boss 35 on the push rod assembly 3, such as... Figure 7 As shown, a rigid axial blocking limit is formed, preventing the limiting boss 35 from moving downwards, and locking the push rod assembly 3, preventing it from being pressed down or slid. This state is suitable for equipment carrying, storage, and standby conditions, and can completely avoid the problems of accidental core activation and oil leakage caused by accidentally pressing the push rod. At the same time, the overlapping area of ​​the air inlet is reduced or closed, which can achieve the effect of standby air control.

[0045] Full liquid, no leakage, coil replacement condition: When the atomizer coil needs to be replaced, first rotate the airflow regulating ring 5 to the second angle, so that the notch 52 on the airflow regulating ring 5 is precisely aligned with the limiting protrusion 35. Figure 5 and Figure 6As shown, the axial obstruction of the push rod assembly 3 by the air regulating ring 5 is released, allowing the limiting boss 35 to pass through the notch 52 and descend, giving the push rod assembly 3 a complete downward stroke. Then, the push rod assembly 3 is pressed down, and it descends axially along the oil tank assembly 1 to the second limiting position. During this process, the first seal 31 on the outer side of the push rod assembly 3 is pressed down and tightly fitted with the fixed seal 4, forming a complete end-face seal. This seals the annular leakage gap between the lower end of the auxiliary oil tank 12 and the atomizing core assembly 2, blocking the channel for leakage of atomizing liquid during core replacement. During the same downward stroke of sealing, the bottom end of the push rod assembly 3 simultaneously pushes the atomizing core assembly 2, ejecting it from the bottom assembly position. Afterward, a new atomizing core can be inserted from the bottom assembly position to complete the core replacement.

[0046] The entire coil replacement process is completed simultaneously during a single downward stroke: "first sealing to prevent leaks, then ejecting the coil for replacement." There's no need to empty the atomizing fluid from the oil tank beforehand, ensuring a clean, leak-free, and quick coil replacement even when the tank is full. After replacing the coil, release the push rod assembly 3. The push rod assembly 3 returns to its first limit position, releasing the seal and reconnecting the oil circuit. The device resumes normal atomization and oil supply. Rotating the air regulating ring 5 again will re-enter the locked anti-accidental-touch state or adjust the air intake to a suitable level, ensuring stable operation of the entire unit.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
