Abstract
The present disclosure provides a heating core for hot air gun use and a hot air gun. The heating core comprises: a mount support; and a heating wire arranged on the mount support; wherein the heating wire includes a close wound segment on a surface of which an insulating layer is provided, an interval between adjacent heating wires in the close wound segment is D, 0≤D≤2 mm. The hot gun comprises a housing in which a hot air device producing hot air is provided, the hot air device comprising a heating core; a hot air tube provided at a front end of the housing, inside the hot air tube being disposed the heating core, wherein: the heating core is the heating core for hot air gun use according to any technical solution above. By providing a close wound segment on the heating wire and arranging an insulating layer on the surface of the heating wire, the heating capacity of the heating wire in the local space is increased, the heating density of the local space is improved, and thus the air-out temperature, working effect, and working efficiency of the hot air gun may be dramatically improved.
