Description

Technical Field

[0002] Currently, in existing atomizing devices, the atomizer cover inside the e-liquid tank is basically connected to the atomizer base via threads or interference fit. Although these two connection methods are relatively convenient for assembly and disassembly, after the atomizer cover is assembled and connected to the atomizer base, there will be a tiny gap between the two at the connection point. When e-liquid is injected into the e-liquid tank, the e-liquid will slowly seep into the lower part of the atomizing chamber through the gap and then flow out through the ventilation channel, causing the atomizing device to leak. Furthermore, this leaked e-liquid can also enter the device used to power the atomizing device, causing a short circuit and thus leading to an unsafe accident. Utility Model Content
