Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an electronic atomizer that prevents leakage of e-liquid. Background Technology

[0002] Electronic atomizers, as a new type of tobacco product, have been widely used globally due to their convenience and adjustability. With increasing market demand, users are constantly raising their performance requirements for electronic atomizers, especially regarding e-liquid leakage prevention. A stable and reliable leak-proof structure has become crucial for improving product quality and user experience.

[0003] Currently, common leak-proof technologies for e-cigarettes mostly employ sealing rings, one-way valves, or simple wicking cotton structures. Sealing rings provide a physical seal at component connections, reducing the risk of e-liquid leakage; one-way valves utilize fluid pressure differences to allow e-liquid to flow in one direction for atomization; and wicking cotton relies on its own absorbency to absorb excess e-liquid and prevent spillage. While these structures provide some degree of leak prevention, their overall technical principles are relatively basic.

[0004] However, existing technologies struggle to effectively address leakage issues in e-cigarettes under complex conditions such as when they are stationary, inverted, or frequently inhaled. Due to the lack of a dynamic leak-proof mechanism, when the device is tilted or not in use, e-liquid can easily flow due to gravity or changes in internal pressure, causing leakage from the mouthpiece. This affects the user experience, can easily lead to short circuits in the device's internal circuitry, and poses a safety hazard. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electronic atomizer that prevents e-liquid leakage, aiming to improve the problem that traditional electronic cigarettes are prone to leakage due to e-liquid flow after being left still, upside down, or inhaled, and that the inhalation port is prone to contact with e-liquid, affecting the user experience.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic atomizer with leak-proof e-liquid, comprising a vapor rod, a power indicator light on the outer wall of the vapor rod, a mouthpiece on the top of the vapor rod, an assembly component on the inner wall of the vapor rod, an intake port on the outer wall of the mouthpiece, and an oil-proof component inside the mouthpiece;

[0007] The leak-proof component includes an oil-absorbing cotton, the outer wall of which is disposed inside the mouthpiece. An oil box is disposed on the lower side inside the mouthpiece. An atomizer body is fixedly connected to the lower surface of the oil box. A filter plate is disposed on the inner wall of the oil box. A spring is fixedly connected to the upper surface of the filter plate. An oil outlet pipe is fixedly connected to the upper side inside the oil box. An elastic column is fixedly connected to the upper surface of the oil-absorbing cotton. A sealing gasket is fixedly connected to one end of the elastic column. An isolation plate is attached to the upper surface of the sealing gasket.

[0008] Furthermore, the assembly includes a connecting rod, the outer wall of which is slidably connected to the inner wall of the cigarette rod, an arc-shaped platform 1 fixedly connected to the outer wall of the connecting rod, an arc-shaped platform 2 fixedly connected to one end of the connecting rod, a strong magnet 1 fixedly connected to the lower surface of the atomizer body, a strong magnet 2 fixedly connected to the inner wall of the cigarette rod, a slide cylinder fixedly connected to the inner wall of the cigarette rod, a slide column slidably connected to the inner wall of the slide cylinder, a limit block fixedly connected to the outer wall of the slide column, a spring 2 fixedly connected to the outer wall of the slide cylinder, a positioning plate fixedly connected to the lower surface of the mouthpiece, and a positioning groove opened on the upper side inside the cigarette rod.

[0009] Furthermore, the outer wall of the limiting block is slidably connected between the first arc-shaped platform and the second arc-shaped platform, and the limiting block is used to fix the connecting rod.

[0010] Furthermore, the outer wall of the positioning plate is slidably connected to the inside of the positioning groove, and the positioning plate and the positioning groove are used for positioning when assembling the mouthpiece and the cigarette rod.

[0011] Furthermore, the lower surface of the strong magnet is slidably connected to the upper surface of the second strong magnet, and the first strong magnet and the second strong magnet are used for initial fixation.

[0012] Furthermore, the oil outlet pipe is fixedly connected inside the suction nozzle, and the upper surface of the oil outlet pipe is disposed on the lower surface of the oil-absorbing cotton.

[0013] Furthermore, the elastic column is disposed between the oil-absorbing cotton and the sealing gasket, and the elastic column is used to push the oil-absorbing cotton and the sealing gasket.

[0014] Furthermore, the isolation plate is disposed on the upper side inside the suction nozzle.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the user inhales, the air pressure inside the mouthpiece decreases, the elastic column contracts and causes the sealing gasket to separate, the oil outlet tube opens and atomizes the e-liquid. After stopping inhalation, the air pressure returns to normal, the elastic column pushes the sealing gasket to block the oil path, and the oil-absorbing cotton absorbs the overflow oil to prevent leakage. This solves the problem that traditional electronic cigarettes are prone to leakage due to the flow of e-liquid after being left still, upside down, or inhaled, and the mouthpiece is prone to contact with e-liquid, affecting the experience. It achieves improved leakage prevention effect, avoids e-liquid contact with the user's mouth, improves safety and cleanliness, and ensures stable and leak-free atomization process.

[0025] 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.

[0026] Reference Figures 1-3 The present invention provides an embodiment of an electronic atomizer that prevents e-liquid leakage, comprising a smoke rod 1, a power indicator light 2 provided on the outer wall of the smoke rod 1, a mouthpiece 3 provided on the top of the smoke rod 1, an assembly component provided on the inner wall of the smoke rod 1, a suction port 4 opened on the outer wall of the mouthpiece 3, and an oil leakage prevention component provided inside the mouthpiece 3.

[0027] The leak-proof component includes an oil-absorbing cotton 16, which absorbs any small amount of e-liquid that may spill out during atomization, preventing un-atomized droplets from directly entering the mouthpiece 4 and improving the purity of the flavor. The outer wall of the oil-absorbing cotton 16 is located inside the mouthpiece 3. An oil box 10 is located on the lower side of the mouthpiece 3. An atomizer body 11 is fixedly connected to the lower surface of the oil box 10. A filter plate 12 is located on the inner wall of the oil box 10. A spring 13 is fixedly connected to the upper surface of the filter plate 12. An oil outlet pipe 14 is fixedly connected to the upper side of the inside of the oil box 10, connecting the oil box 10 and the mouthpiece 3 and controlling the e-liquid flow path. An elastic column 18 is fixedly connected to the upper surface of the oil-absorbing cotton 16. The elastic column 18 expands and contracts according to the air pressure changes inside the mouthpiece 3, driving the sealing gasket 17 to open or close the oil outlet pipe 14. A sealing gasket 17 is fixedly connected to one end of the elastic column 18. An isolation plate 15 is attached to the upper surface of the sealing gasket 17.

[0028] Specifically, when the user inhales, the air pressure inside the mouthpiece 3 decreases, and the pressure difference causes the elastic column 18 to contract, which in turn causes the sealing gasket 17 to separate from the isolation plate 15. The oil outlet pipe 14 opens, and the atomizer body 11 heats the e-liquid in the oil box 10 to atomize it. The atomized e-liquid is filtered through the oil outlet pipe 14 and then discharged from the mouthpiece 4. The oil absorbent cotton 16 absorbs the overflowing e-liquid to prevent it from flowing into the mouthpiece 4. After the user stops inhaling, the air pressure inside the mouthpiece 3 returns to normal, and the elastic column 18 pushes the sealing gasket 17 to re-adhere to the isolation plate 15, blocking the connection between the oil outlet pipe 14 and the mouthpiece 4, preventing e-liquid leakage and backflow when the device is stationary or inverted.

[0029] Reference Figures 1-5The assembly includes a connecting rod 7, whose outer wall is slidably connected to the inner wall of the vaporizer 1. An arc-shaped platform 19 is fixedly connected to the outer wall of the connecting rod 7, and an arc-shaped platform 20 is fixedly connected to one end of the connecting rod 7. A groove is formed on the outer wall of the connecting rod 7, which cooperates with a limiting block 21 to achieve mechanical engagement and fix the position of the connecting rod 7. A strong magnet 8 is fixedly connected to the lower surface of the atomizer body 11, and a strong magnet 9 is fixedly connected to the inner wall of the vaporizer 1. A slide cylinder 22 is fixedly connected to the inner wall of the vaporizer 1, and a sliding column 23 is slidably connected to the inner wall of the slide cylinder 22. A limiting block 21 is fixedly connected to the outer wall of the sliding column 23. By engaging the groove of the connecting rod 7, the axial and radial movement of the connecting rod 7 is restricted, preventing the assembly from loosening. A spring 24 is fixedly connected to the outer wall of the slide cylinder 22. The lower surface of the mouthpiece 3 is fixed... The device is connected to a positioning plate 5. A positioning groove 6 is provided on the upper side of the inside of the cigarette rod 1. The outer wall of the limiting block 21 is slidably connected between the first arc platform 19 and the second arc platform 20. The limiting block 21 is used to fix the connecting rod 7. The outer wall of the positioning plate 5 is slidably connected inside the positioning groove 6. The positioning plate 5 and the positioning groove 6 are used for positioning when the mouthpiece 3 is assembled with the cigarette rod 1. The lower surface of the first strong magnet 8 is slidably connected to the upper surface of the second strong magnet 9. The first strong magnet 8 and the second strong magnet 9 are used for the first fixation. The oil outlet pipe 14 is fixedly connected inside the mouthpiece 3. The upper surface of the oil outlet pipe 14 is set on the lower surface of the oil-absorbing cotton 16. The elastic column 18 is set between the oil-absorbing cotton 16 and the sealing gasket 17. The elastic column 18 is used to push the oil-absorbing cotton 16 and the sealing gasket 17. The isolation plate 15 is set on the upper side of the inside of the mouthpiece 3.

[0030] Specifically, when installing the mouthpiece 3, the positioning plate 5 is inserted into the positioning groove 6 of the e-cigarette rod 1 to complete the initial positioning and ensure the alignment of the parts. The inner slide cylinder 22, slide column 23 and spring 24 of the e-cigarette rod 1 form an elastic structure. Under the elastic force of spring 24, the limiting block 21 is inserted between the arc-shaped platform 19 and arc-shaped platform 20 of the connecting rod 7, fixing the connecting rod 7 and firmly installing the atomizer body 11. At the same time, the strong magnet 8 on the lower surface of the atomizer body 11 and the strong magnet 9 on the inner wall of the e-cigarette rod 1 are magnetically attracted to form a double fixing structure, which enhances the connection stability.

[0031] Working principle: When the user inhales, the air pressure inside the mouthpiece 3 decreases. Under the action of the air pressure difference, the elastic column 18 contracts, causing the sealing gasket 17 to separate from the isolation plate 15, and the oil outlet pipe 14 opens. At this time, the atomizer body 11 starts to work, heating the e-liquid in the oil box 10. The e-liquid is heated and atomized into mist, which is filtered through the oil outlet pipe 14 and the absorbent cotton 16 and discharged from the mouthpiece 4. Since the absorbent cotton 16 is located above the oil outlet pipe 14, it can absorb any small amount of e-liquid that may overflow in time, preventing the e-liquid from flowing directly into the mouthpiece 4. When the user stops vaping, the air pressure inside the mouthpiece 3 returns to normal, the elastic column 18 returns to its original state, and under its pre-tightening force, pushes the sealing gasket 17, so that the sealing gasket 17 re-fits tightly against the isolation plate 15, blocking the connection between the oil outlet pipe 14 and the mouthpiece 4. In this way, even if the electronic atomizer is in a static or inverted state, the e-liquid is difficult to leak through the oil outlet pipe 14, effectively preventing e-liquid backflow and leakage.

[0032] In addition, the mouthpiece 3 is initially positioned by the positioning plate 5 and the positioning groove 6 of the e-cigarette rod 1 to ensure accurate docking of the mouthpiece 3 and the e-cigarette rod 1. The sliding cylinder 22, sliding column 23 and spring 24 inside the e-cigarette rod 1 form an elastic structure. Under the action of spring 24, the limiting block 21 is inserted between the arc-shaped platform 19 and arc-shaped platform 20 of the connecting rod 7 to fix the connecting rod 7, thereby firmly installing the atomizer body 11 inside the e-cigarette rod 1. At the same time, the strong magnet 8 on the lower surface of the atomizer body 11 and the strong magnet 9 on the inner wall of the e-cigarette rod 1 are attracted by magnetic force to further enhance the connection stability and form a double fixing structure.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
