Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a leak-proof sealing structure for electronic cigarette atomizers. Background Technology
[0002] E-cigarettes are electronic products that mimic traditional cigarettes, possessing the same appearance, smoke, taste, and feel. They are powered by rechargeable lithium polymer batteries that drive an atomizer, heating e-liquid in a tank to vaporize nicotine and other substances for inhalation. The World Health Organization has conducted research on e-cigarettes and concluded that they are harmful to public health and are not a means of quitting smoking; therefore, they must be strictly regulated to prevent harm to adolescents and non-smokers. Currently available e-cigarettes all suffer from e-liquid leakage. When adding too much e-liquid to the atomizer chamber, it leaks between the atomizer and the chamber, affecting normal use and potentially damaging the device.
[0003] A leak-proof e-cigarette structure for electronic cigarettes, disclosed in publication number CN216493484U, includes a polymer battery body with a switch button on its outer wall, an atomizer at its top, and a sealing structure at its top. This sealing structure comprises a connecting ring, an upper sealing ring, and a lower sealing ring, with connecting mechanisms on its four outer sides. This invention, belonging to the field of electronic cigarettes, utilizes a sealing structure to achieve a tight seal between the atomizer and the atomizing chamber, preventing excessive e-liquid leakage. The connecting mechanisms connect the sealing structure between the atomizer and the atomizing chamber, facilitating installation and repair. The combined use of the sealing structure and connecting mechanisms improves the sealing performance between the atomizer and the atomizing chamber, preventing e-liquid leakage and ensuring normal user operation, thus preventing damage to the e-cigarette device.
[0004] While the aforementioned patent achieves a seal between the atomizer and the atomizing chamber through a designed sealing structure to prevent excessive e-liquid from leaking out, and includes a connecting mechanism to facilitate installation and repair, the device relies solely on an upper and lower sealing ring for leak prevention. This insufficient sealing performance is problematic because rubber sealing rings deform over time, gradually reducing the contact pressure with the mating surface. This creates tiny gaps in the previously tight seal, allowing e-liquid to leak through. Summary of the Invention
[0005] (a) Technical problems to be solved The purpose of this invention is to provide a sealing structure for a leak-proof atomizer in electronic cigarettes, which solves the problem in the background art where only upper and lower sealing rings are used for sealing, resulting in poor sealing performance. Furthermore, as the rubber sealing ring is used for a long time, its deformation capacity decreases, the contact pressure between the sealing ring and the mating surface gradually decreases, and tiny gaps appear in the originally tight sealing interface, allowing e-liquid to leak along the gaps.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for an electronic cigarette atomizer that prevents leakage, comprising a sealing element, a sealing groove inside the sealing element, an anti-leakage mechanism installed inside the sealing groove, an atomizer attached to the bottom of the sealing element, extension plates fixedly connected to both sides of the atomizer, a rotating joint fixedly connected to the surface of the extension plate, and a disassembly / removal mechanism rotatably connected to the surface of the rotating joint. The leak-proof mechanism includes an annular spring installed inside the sealing groove, with an upper sealing ring overlapping the top of the annular spring and a lower sealing ring overlapping the bottom of the annular spring. The disassembly and assembly mechanism includes a fixed rod rotatably connected to the surface of the rotary joint, a support spring fixedly connected inside the fixed rod, a telescopic rod fixedly connected to the top of the support spring, a limit block fixedly connected to the top of the telescopic rod, and a limit post inserted inside the limit block.
[0007] As a further embodiment of this utility model, a limiting groove is provided inside the fixed rod, and the telescopic rod is slidably connected inside the limiting groove. The limiting groove serves to limit the telescopic rod.
[0008] As a further embodiment of this utility model, an extension block is fixedly connected to the bottom of the limiting post, an atomizing chamber is fixedly connected to one side of the extension block, and a mouthpiece is fixedly connected to the top of the atomizing chamber. The extension block serves to support the limiting post.
[0009] As a further embodiment of this utility model, the atomizing chamber overlaps the top of the sealing element, and both sides of the atomizing chamber are fixedly connected with locking blocks. The locking blocks serve to fix the sealing element.
[0010] As a further embodiment of this utility model, the card block has a card slot inside, and a card plate is slidably connected inside the card slot. The card plate serves to connect the card slot.
[0011] As a further embodiment of this utility model, both sides of the sealing element are fixedly connected to limit plates, and the limit plates are provided with limit holes that are compatible with the snap-fit plate. The limit plates are designed to limit the snap-fit plate.
[0012] As a further embodiment of this utility model, a polymer battery cell body is installed at the bottom of the atomizer, and a switch button is provided on the surface of the polymer battery cell body. The switch button controls the atomizer to start.
[0013] This utility model provides a leak-proof sealing structure for an electronic cigarette atomizer, which has the following advantages: 1. The leak-proof atomizer sealing structure for electronic cigarettes features a leak-proof mechanism. During use, a seal is installed at the connection gap between the atomizing chamber and the atomizer. Upper and lower sealing rings are located at the top and bottom of the seal to seal the interface. In conjunction with the ring springs overlapping on one side of the upper and lower sealing rings, the continuous rebound potential energy of the ring springs actively replenishes the pressure of the sealing rings, which experience reduced deformation and contact pressure over time. This fills any tiny gaps that may appear at the sealing interface, preventing e-liquid leakage.
[0014] 2. The leak-proof atomizer sealing structure for electronic cigarettes, through the design of the disassembly and assembly mechanism, allows for quick disassembly of the seal by simply pulling the telescopic rod upwards to separate the limiting block at the top of the telescopic rod from the limiting post at the bottom. Then, the rotating joint at the bottom of the fixing rod is rotated, and finally, the atomizer at the bottom of the seal is moved to allow the snap-fit plates on both sides of the atomizer to be pulled out from the limiting plates on both sides of the seal. This eliminates the need for bolt installation and improves the disassembly and assembly efficiency for installers. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example
[0018] Please see Figures 1 to 4This utility model provides a technical solution: a tape coating thickness control device, including a sealing element 1. Limiting plates 11 are fixedly connected to both sides of the sealing element 1. Limiting holes for matching snap-fit plates 10 are opened inside the limiting plates 11. A sealing groove is opened inside the sealing element 1, and a leak-proof mechanism 2 is installed inside the sealing groove. The leak-proof mechanism 2 significantly improves the sealing reliability of the connection gap between the atomizing chamber 8 and the atomizer 3, completely avoiding the risk of e-liquid leakage. The atomizer 3 is attached to the bottom of the sealing element 1. A polymer battery cell body 13 is installed at the bottom of the atomizer 3. A switch button 14 is provided on the surface of the polymer battery cell body 13. Extension plates 4 are fixedly connected to both sides of the atomizer 3. Rotary joints 5 are fixedly connected to the surface of the extension plates 4. A disassembly and assembly mechanism 6 is rotatably connected to the surface of the rotary joints 5. The disassembly and assembly mechanism 6 eliminates the need for bolts. The installation method improves the installation efficiency of the installers. The leak-proof mechanism 2 includes an annular spring 201 installed inside the sealing groove. The top of the annular spring 201 is overlapped with an upper sealing ring 202, and the bottom of the annular spring 201 is overlapped with a lower sealing ring 203. The disassembly and assembly mechanism 6 includes a fixed rod 601 rotatably connected to the surface of the rotating joint 5. A limit groove is opened inside the fixed rod 601. A telescopic rod 603 is slidably connected inside the limit groove. A support spring 602 is fixedly connected inside the fixed rod 601. A telescopic rod 603 is fixedly connected to the top of the support spring 602. A limit block 604 is fixedly connected to the top of the telescopic rod 603. A limit post 605 is inserted inside the limit block 604. An extension block 7 is fixedly connected to the bottom of the limit post 605. An atomizing chamber 8 is fixedly connected to one side of the extension block 7. A mouthpiece 12 is fixedly connected to the top of the atomizing chamber 8. Furthermore, the atomizing chamber 8 is attached to the top of the sealing element 1. As the connecting carrier for oil storage and atomization, the precise attachment of the atomizing chamber 8 to the sealing element 1 lays the foundation for subsequent sealing reinforcement. It acts on the upper sealing ring 202 through its own gravity and subsequent locking force. Both sides of the atomizing chamber 8 are fixedly connected with locking blocks 9. The locking blocks 9 serve as the connecting and positioning carrier. Through precise alignment with the atomizing structure, they provide a stable sliding and locking reference for the locking plate 10. The locking blocks 9 have locking grooves inside, and the locking plate 10 is slidably connected inside the locking grooves. The locking plate 10 serves as a mechanical locking actuator, and the connection between the atomizing chamber 8 and the atomizing structure is realized through sliding.
[0019] In this invention, the working steps of the device are as follows: First step: When in use, a sealing element 1 is set at the connection gap between the atomizing chamber 8 and the atomizer 3, and an upper sealing ring 202 and a lower sealing ring 203 are set at the top and bottom of the sealing element 1 to seal the interface. In conjunction with the ring spring 201 overlapping on one side of the upper sealing ring 202 and the lower sealing ring 203, the continuous rebound potential energy of the ring spring 201 is used to actively replenish the pressure of the sealing ring, which has reduced deformation capacity and contact pressure as the usage time increases. The second step: When using it, simply pull the telescopic rod 603 upwards so that the limiting block 604 at the top of the telescopic rod 603 separates from the limiting post 605 at the bottom. Then rotate the rotating joint 5 at the bottom of the fixing rod 601, and finally move the atomizer 3 at the bottom of the seal 1 so that the snap-fit plates 10 on both sides of the atomizer 3 are pulled out from the limiting plates 11 on both sides of the seal 1. This completes the quick disassembly of the seal 1.
