Heat Gun Formed By Wave-type Heating Bodies

Abstract

Provided is a heat gun formed by wave-type heating bodies. The heat gun includes a housing assembly and a heating assembly mounted in the housing assembly, where an air supply assembly is fixedly mounted in the housing assembly. The heating wire is wound into a wave-type structure by dedicated equipment. Compared with a traditional slingshot-wire-type structure, the wave-type structure is capable of resisting deformation of the heating wire at a high temperature and in a process from a high temperature to a normal temperature such that defects caused by thermal expansion and contraction when the heating wire operates or stops can be avoided. After the wave-type structure of the heating wire is wound around a mica plate, a direction of the wave-type structure is exactly perpendicular to a direction of an air channel such that wind generated by a fan behind can blow out heat with maximum efficiency.
