Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette with separable e-liquid. Background Technology

[0002] Currently, in existing e-cigarettes, e-liquid is pre-filled into the reservoir using an automatic filling device before leaving the factory. The reservoir is then completely sealed. During filling, the strong impact of the automatic filling device causes some e-liquid to impact the atomizer tube, leading to leakage. Furthermore, pre-filling the reservoir means the e-cigarette will remain unused for extended periods during storage and transportation. This prolonged immersion of the atomizer tube and heating element in the reservoir causes corrosion, shortening their lifespan. Utility Model Content
