Description

Technical Field

[0001] This utility model belongs to the field of electronic cigarette technology, and in particular relates to an electronic cigarette with waterproof and dustproof functions. Background Technology

[0002] Electronic cigarettes (also known as electronic nicotine delivery systems, or ENDS for short) are devices that heat a liquid to produce an aerosol for users to inhale. Electronic cigarettes are powered by batteries and heat a liquid (e-liquid) containing nicotine, flavorings and other chemicals, turning it into an aerosol (not real "vapor"), which users inhale through a mouthpiece.

[0003] Current electronic cigarettes typically seal the mouthpiece with a cap to achieve waterproofing and dustproofing. However, repeated insertion and removal of the cap can loosen the fit between the cap and the mouthpiece, allowing the cap to easily detach and for dirt to enter the mouthpiece's inner hole and be inhaled. Furthermore, when e-liquid leaks from the atomizing chamber onto the inner wall of the mouthpiece, it can be inhaled, thus affecting human health. Therefore, we propose an electronic cigarette with waterproof and dustproof functions. Utility Model Content

[0053] Example 7:

[0054] This embodiment provides an electronic cigarette with waterproof and dustproof functions. In addition to the technical solutions of the above embodiments, it also has the following technical features: the outer wall of the mouthpiece 9 is provided with a slot 20, which can engage with the left end of the first sealing push plate 2; the top of the upper cover 1 and the outer shell 3 are both provided with through holes, which are aligned vertically with the mouthpiece 9.

[0055] The nozzle 9 can be limited by the engagement of the first sealing push plate 2 and the slot 20.

[0056] Working principle: When the electronic cigarette needs to be used, first push the first sealing push plate 2 to the right and compress the second spring 21, so that the through hole at the top of the cover 1 is opened. Then, push the second sealing push plate 4 upward, so that the second sealing push plate 4 drives the liquid tank 6, the inner shell 8 and the mouthpiece 9 to move upward together. When the upper end of the mouthpiece 9 passes through the through hole, the first sealing push plate 2 is released. Then, the first sealing push plate 2 will press tightly against the right side wall of the mouthpiece 9 under the pressure of the second spring 21. Continue to push the second sealing push plate 4. After the guide rod 14 abuts against the inner wall of the inner shell 8, the first spring 21 is compressed. Spring 15 causes guide rod 14 to drive sealing block 17 downward along the inner wall of inner shell 8 until sealing seat 16 separates from sealing block 17. It stops when the left end of first sealing push plate 2 is aligned with slot 20. First sealing push plate 2 restricts the downward movement of suction nozzle 9. Then, air is sucked in through the upper end of suction nozzle 9, creating a negative pressure in the upper cavity of inner shell 8. This causes gas in the lower space to be transported to the upper cavity through the inner hole of microporous vent tube 19. At this time, airflow sensor 18 detects the airflow and transmits the signal to circuit board 12. Then, circuit board 12 controls heating wire. Heating is performed by the heating wire 11. The e-liquid in the reservoir 6 is drawn to the wicking cotton 10 through the absorbent cotton tube 13, so that the heating wire 11 can heat and atomize the e-liquid on the wicking cotton 10. Finally, the atomized e-liquid is delivered to the mouth through the mouthpiece 9. When the e-cigarette is no longer needed, the first sealing push plate 2 can be pushed to the right to separate it from the slot 20. Then, the second sealing push plate 4 can be pushed down to retract the mouthpiece 9 into the outer shell 3. During the separation of the guide rod 14 from the inner wall of the outer shell 3, the compressed first spring 15 will return to its original state and push upward. The guide rod 14 is moved so that the sealing block 17 and the sealing seat 16 are re-fitted, thereby sealing the lower port of the mouthpiece 9 and preventing e-liquid from flowing into the inner wall of the mouthpiece 9. When the first sealing push plate 2 is pushed to the leftmost end of the bottom groove of the upper cover 1, the first sealing push plate 2 will seal the through hole on the upper cover 1 to prevent the mouthpiece 9 from being contaminated by external dirt. The tight fit between the first sealing push plate 2 and the sealing gasket 5 can improve the sealing performance and provide a waterproof effect. The tight fit between the sealing gasket 5 on the second sealing push plate 4 and the outer shell 3 can improve the sealing performance at the opening on the right side of the outer shell 3.

[0057] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
