A semi-enclosed heating element for an electronic cigarette

By designing a semi-enclosed heating element, the problems of complex structure and poor sealing of existing electronic cigarette heating chambers have been solved, resulting in improved sealing, faster oil intake and improved atomization performance. This reduces the risk of oil leakage and dry burning, and improves atomization uniformity and flavor consistency.

AI Technical Summary

Technical Problem

The heating chamber of existing electronic cigarettes has a through-hole structure, which results in a complex structure, poor sealing, slow oil intake, and affects atomization performance.

Method used

A semi-enclosed heating element is designed, with a certain thickness of "semi-enclosed" structure at the bottom of the heating cavity. The second surface of the main body directly contacts the oil cavity to form a sealing barrier, eliminating the need for additional seals, increasing the area of ​​the oil inlet hole, and simplifying the structure.

Benefits of technology

It improves sealing performance, reduces the risk of oil leakage, simplifies the assembly process, increases oil intake efficiency, ensures stable delivery of e-liquid, reduces the risk of dry burning, and improves atomization uniformity and flavor consistency.
