Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette with an oil-leakage-proof structure. Background Technology
[0002] Electronic cigarettes are electronic products that mimic the appearance, smoke, taste, and feel of cigarettes. 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 the user to inhale. Electronic cigarettes mainly consist of four parts: e-liquid (containing nicotine, flavorings, and solvents such as propylene glycol), a heating system, a power source, and a filter. They produce aerosols with specific flavors through heating and vaporization for users to consume.
[0003] For example, an electronic cigarette with an oil-leakage-proof structure disclosed in application number 202110929954.0 uses a threaded battery connector to facilitate connection between the battery connector and the vaporizer, thereby simplifying installation and removal and improving efficiency. However, the filling hole of the above structure is side-mounted during use, which makes it prone to oil leakage, reducing its protection and oil-leakage-proof efficiency. Furthermore, it cannot effectively seal, leading to smoke leakage and reducing its sealing performance and usability. Therefore, we propose an electronic cigarette with an oil-leakage-proof structure. Summary of the Invention
