Technical field

The invention belongs to the technical field of electronic cigarettes and electric heated cigarettes, and particularly relates to a smoking device with a metal fiber sheet.

Background technique

At present, e-cigarette products based on electronic atomization technology have reached a technical bottleneck stage.
