AI Technical Summary

Technical Problem

The existing electronic cigarette's battery cell is sealed inside the main unit and cannot be disassembled, leading to failure or inability to replace it after its lifespan, resulting in the main unit being scrapped; when the cartridge is inserted or removed from the adapter cavity, the magnet becomes loose or comes off, affecting the connection stability; the amount of e-liquid in the cartridge cannot be observed, causing the heating element to burn dry after the e-liquid is consumed.

Method used

The device features a detachable battery structure, with the magnet secured by screws. An observation window is provided on the main unit, allowing the cartridge and magnet to be freely inserted and removed. The e-liquid storage chamber is transparent and visible, and the atomizing tube is electrically connected to the heating element.

Benefits of technology

It enables the battery to be detachable and replaceable, prevents the magnet from becoming loose, allows the e-liquid level to be monitored, avoids dry burning, and improves the lifespan and user experience of e-cigarettes.

Abstract

This utility model discloses a multifunctional electronic cigarette, including a cartridge, a main unit, a battery cell, and a casing. The main unit has an adapter cavity, a receiving cavity, and a window corresponding to and communicating with the adapter cavity. The battery cell is detachably installed in the receiving cavity. The casing is fitted onto the main unit to cover the receiving cavity. The bottom wall of the adapter cavity is provided with a magnet and a screw for fixing the magnet. The cartridge is inserted into the adapter cavity corresponding to the window. The bottom of the cartridge is provided with an iron shell corresponding to the magnet. The cartridge is attracted to the iron shell by the magnet and can be freely inserted and removed in the receiving cavity. This utility model, by adopting the above technical solution, solves the problems of existing electronic cigarettes with replaceable cartridges, where the battery cell is sealed inside the main unit and cannot be removed, leading to the entire main unit becoming unusable due to the inability to replace it after a malfunction or reaching the end of its lifespan; the magnetic attraction when inserting or removing the cartridge in the adapter cavity pulls out the magnet along with it; and the lack of a window in the receiving cavity to observe the e-liquid level, causing the cartridge to dry-burn after the e-liquid is depleted.
