[0002] Electronic atomizers, also known as e-cigarettes or vaporizers, are devices that generate vapor by heating liquid e-liquid to simulate the smoking experience. They mainly consist of a battery, an atomizer, e-liquid, and an airway. The battery provides power to the device, and the heating element in the atomizer heats the e-liquid with an electric current to generate vapor, which is then inhaled through the airway.
[0003] When using an electronic atomizer, the heating wire inside the atomizer heats the e-liquid, turning it into vapor for inhalation. However, traditional electronic atomizers either lack a filter or have an overly simple filter at the input end. When impurities or tar clog the filter, blockage occurs, affecting the flow of e-liquid. Furthermore, traditional electronic atomizers lack filter replacement functionality or the replacement method is overly complicated. Therefore, a multi-layer filtration structure for electronic atomizers is proposed to address these issues. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a multi-layer filter structure for an electronic atomizer, which aims to improve the problems of traditional electronic atomizers where the atomizer input end does not have a filter or has an overly simple filter. When impurities or tar clog the filter, blockage will occur, affecting the flow of e-liquid. Furthermore, traditional electronic atomizers do not have the function of replacing the filter or the replacement method is too complicated.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer filter structure for an electronic atomizer, comprising an atomizer body, an output end fixedly connected to the top of the atomizer body, an installation ring fixedly connected to the bottom of the atomizer body, a replacement component installed outside the installation ring, and a dustproof component installed outside the atomizer body.
[0006] The replacement component includes a collar, the inner side of which is slidably connected to the outside of the mounting ring.

[0008] The dustproof component includes a housing, which is fixedly connected to the outside of the atomizer body. A baffle is slidably connected to the inner wall of the housing. A second spring is fixedly connected to the top of the baffle. A sliding rod is sleeved inside the second spring. A fixing block is fixedly connected to the top of the sliding rod. A protective cover is fixedly connected to the outside of the fixing block.
[0009] As a further description of the above technical solution:
[0010] The rope is externally slidably connected inside the fixed ring, and the rope is internally fixedly connected to the outside of the slide plate.
[0011] As a further description of the above technical solution:
[0012] The outer side of the spring is fixedly connected to the inner wall of the fixed ring, and the outer side of the slide plate is slidably connected to the inner wall of the fixed ring.

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, when replacing the filter, the user manually rotates the rotating ring, and the rope on the inner wall of the rotating ring is pulled, which in turn drives the slide plate to slide along the inner wall of the fixed ring. During the movement of the slide plate, the compressed spring 1 accumulates elastic potential energy, and at the same time, the plug connected to the slide plate gradually retracts into the fixed ring, releasing the lock on the atomizer body. Then, the atomizer body is removed and a new filter is installed. After the body is pulled out and the filter is replaced, the rotating ring is released, the spring 1 releases its elastic force to push the slide plate back to its original position, and the plug automatically pops out and relocks. The whole operation is easy and convenient, greatly improving maintenance efficiency.
[0023] 2. In this utility model, by pulling the protective cover, the slide rod pulls the baffle to compress the second spring. Then, the protective cover is turned to the outside to open the output end. The reverse operation can cover the output end with the protective cover. This allows the output end to be covered by the protective cover when not in use, preventing impurities or dust from entering the output end and causing blockage inside the atomizer, generating resistance and affecting inhalation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1-4 The present invention provides an embodiment of an electronic atomizer multi-layer filter structure, comprising an atomizer body 1, an output end 2 fixedly connected to the top of the atomizer body 1, and an installation ring 3 fixedly connected to the bottom of the atomizer body 1. The atomizer body 1 is installed on the top of the electronic atomizer for atomizing e-liquid. The output end 2 is for convenient inhalation by the user. The installation ring 3 is used to cooperate with the plug rod 11 to fix the installation ring 4 on the collar 4, thereby fixing the atomizer body 1 and facilitating the replacement of the filter 5. A replacement component is installed on the outside of the installation ring 3, and a dustproof component is installed on the outside of the atomizer body 1.
[0032] The replacement components include a collar 4, which is slidably connected to the outside of a mounting ring 3. Multiple filter elements 5 are slidably connected inside the collar 4. A fixing ring 6 is fixedly connected to the outside of the collar 4. A rotating ring 7 is rotatably connected to the outside of the fixing ring 6. Four ropes 8 are fixedly connected to the inside of the rotating ring 7. A spring 9 is sleeved on the outside of the ropes 8. A slide plate 10 is fixedly connected to the inside of the spring 9. A rod 11 is fixedly connected to the inside of the slide plate 10. The collar 4 is used to fix itself to the top of the electronic atomizer via threads. The filter elements 5 are used to filter impurities in the e-liquid. The fixing ring 6 is used to connect and limit other parts. The rotating ring 7 encloses the fixing ring 6 and is connected to the ropes 8 for easy rotation. The ropes 8 are used to pull the slide plate 10 to move. The spring 9 is used to automatically reset the slide plate 10. The rod 11 can only move in a specified direction under the limitation of the fixing ring 6. It will not move or shake randomly. A sliding plate 10 is fixed on its outer side to prevent the insertion rod 11 from falling off due to exceeding its range of movement. The insertion rod 11 is used to fix the atomizer body 1 to the fixing ring 6 for easy replacement of the filter 5. The rope 8 is externally slidably connected to the inside of the fixing ring 6, and the inside of the rope 8 is fixedly connected to the outside of the sliding plate 10, so that when the rope 8 moves, it can pull the sliding plate 10 to move. The outside of the spring 9 is fixedly connected to the inner wall of the fixing ring 6 to keep the spring 9 stable. The sliding plate 10 is externally slidably connected to the inner wall of the fixing ring 6, and the insertion rod 11 is externally slidably connected to the inside of the fixing ring 6. The fixing ring 6 simultaneously restricts the movement direction of the sliding plate 10 and the insertion rod 11. The insertion rod 11 is externally slidably connected to the inside of the collar 4 to restrict the movement direction of the insertion rod 11. The insertion rod 11 is externally inserted into the inside of the mounting ring 3, thereby fixing the atomizer body 1.
[0033] Reference Figures 1-4 The dustproof assembly includes a housing 12, which is fixedly connected to the outside of the atomizer body 1. A baffle 13 is slidably connected to the inner wall of the housing 12. A second spring 14 is fixedly connected to the top of the baffle 13. A sliding rod 15 is sleeved inside the second spring 14. A fixing block 16 is fixedly connected to the top of the sliding rod 15. A protective cover 17 is fixedly connected to the outside of the fixing block 16. The housing 12 is used to connect and protect the internal parts. The baffle 13 is used to compress the second spring 14 and drive the sliding rod 15 to move. The second spring 14 is used to push the baffle 13 to reset. Rod 15 is used to drive the fixed block 16 to move, and the fixed block 16 is used to drive the protective cover 17 to move synchronously. The protective cover 17 is used to cover the output end 2 to prevent impurities from entering. The slide rod 15 is externally slidably connected to the inside of the outer shell 12 to limit the movement direction of the slide rod 15. The protective cover 17 is internally slidably connected to the outside of the output end 2 to prevent dust from entering. The bottom end of the slide rod 15 is fixedly connected to the upper side of the baffle 13 so that the baffle 13 and the slide rod 15 move synchronously. The second spring 14 is externally sleeved inside the outer shell 12 to keep the second spring 14 stable.
[0034] Working Principle: When the user prepares to use the e-cigarette, first open the protective cover. Pinch the protective cover 17 with your fingers and apply an upward pulling force. The protective cover 17 then moves the fixing block 16 together. The fixing block 16 is tightly connected to the slide rod 15. During the movement, the slide rod 15 is pulled by the force and pulls the baffle 13, which compresses the spring 14. At this time, the protective cover 17 can slide out from the outside of the output end 2. Then, rotate the slid-out protective cover 17 180° along the axial direction of the slide rod 15, so that it is deflected to the side of the atomizer body 1, fully exposing the output end 2. At this time, the e-cigarette is ready to use. During inhalation, after the e-liquid flows out of the storage chamber, it will flow through multiple filter sheets 5 in sequence. These filter sheets 5 use multi-layer composite filter material. The fine filter structure can effectively intercept impurities, particles, and sediments in the e-liquid. Only after being filtered and purified layer by layer will the e-liquid enter the atomizer body 1. In the body 1, the e-liquid is rapidly atomized into fine vapor by the heating wire for the user to inhale. After a period of use, the filter 5 will become clogged due to the adhesion of tar and impurities, hindering the smooth passage of e-liquid. At this time, the filter 5 needs to be replaced in time. When replacing, the user manually rotates the rotating ring 7, which drives the rope 8. The rope 8 pulls the slide plate 10 to compress the spring 9, which in turn drives the insert rod 11 into the fixing ring 6 until the insert rod 11 is completely separated from the mounting ring 3. At this time, the fixed state of the atomizer body 1 is released, and the user can easily pull the atomizer body 1 out of the collar 4, take out the old filter 5, and replace it with a new filter 5. Then, insert the mounting ring 3 into the collar 4, release the rotating ring 7, and under the limiting action of the fixing ring 6, the spring 9 quickly releases its elastic potential energy, pushes the slide plate 10, and quickly pushes out the insert rod 11, so that it is inserted into the mounting ring 3, and the atomizer body 1 is firmly fixed again. The whole replacement process is simple, labor-saving and efficient.
