Abstract

A heating wire of an electronic atomizing device includes a central end, a distal end, and a plurality of spiral heating coils extending between the central end and the distal end. The plurality of spiral heating coils is coplanar and surrounds the central end. A mounting gap is formed between any two adjacent spiral heating coils in an extending direction of a reference line connecting the center end and the distal end. The widths of the mounting gaps gradually decrease along the extending direction of the reference line away from the central end. An electronic atomizing device including the aforementioned heating wire is further provided.
