Description

TECHNICAL FIELD OF THE INVENTION

The present application generally relates to electronic cigarette, and more particularly, to an electronic cigarette and a method for manufacturing component thereof.

BACKGROUND OF THE INVENTION

Current electronic cigarettes generally utilize brass as material for cartridge. The main processing technology is turning. However, it is necessary to add more lead in the brass for better turning, which may affect human health. In addition, subsequent surface treatments such as gold electroplating or tin-cobalt alloy electroplating are required after turning, increasing the heavy metal content which may be absorbed into human body.
Plastic is also utilized for manufacturing cartridge. However, the plastic may melt due to its low melting point. Specifically, the atomizing process requires a temperature of 250° C.-300° C. but the melting point of plastic is generally around 250° C. As such, the plastic may melt if used improperly, causing other risks.
