[0002] An e-cigarette is an electronic device designed to simulate the experience of smoking a cigarette. It uses vaporization technology to convert nicotine-containing e-liquid into vapor, which users can inhale instead of producing smoke through combustion like traditional cigarettes.
[0003] The battery tube, also known as the battery compartment cover, is a hollow cylindrical structure in an e-cigarette device used to house and secure a replaceable cylindrical lithium battery. It is a core component of mechanical mods or some replaceable battery e-cigarette devices, serving as both a structural shell and a means of electrical conduction and safety protection.
[0004] Existing battery tube bottom covers typically use a threaded structure to connect to the e-cigarette rod. However, during long-term use, the threads on the bottom cover are prone to wear and stripping due to repeated tightening and friction with the threads on the inner wall of the battery tube. This results in the bottom cover not being able to be tightened properly. To address this issue, the inventor has proposed an easy-to-install electronic cigarette battery tube bottom cover to solve the aforementioned technical problems. Utility Model Content
