AI Technical Summary

Technical Problem

Existing e-cigarette technologies face issues with high-viscosity e-liquid causing poor ventilation due to low fluidity, leading to increased battery energy consumption and vent channel blockage from e-liquid drawn by inhalation resistance.

Method used

An atomization assembly with a housing assembly featuring a vent channel isolated from the atomization tank, where the heating element is positioned between the e-liquid and atomization tanks, and an air channel wall is partially located in the atomization tank to transfer heat, ensuring smooth e-liquid flow and preventing e-liquid from entering the vent channel.

Benefits of technology

This design maintains e-liquid fluidity without additional power consumption, prevents vent channel blockage, and simplifies the assembly structure while ensuring smooth ventilation and reduced energy costs.

Abstract

An atomization assembly includes a housing assembly and a heating element. The housing assembly is formed with an e-liquid tank and an atomization tank spaced apart from each other. The housing assembly is further formed with an air inlet channel and a vent channel. The air inlet channel is in communication with the atomization tank. The vent channel is in communication with the e-liquid tank. The atomization tank is isolated from the vent channel. The housing assembly includes an air channel wall forming the vent channel. The air channel wall is at least partially located in the atomization tank.
