Hair straightener heating element

Abstract

A hair straightener heating element comprises: a base, a working plate, a heating sheet, a thermal insulation sheet, and a silica gel pad. The base is provided with an accommodation groove thereon. The silica gel pad is arranged in the accommodation groove. The thermal insulation sheet is fitted into the silica gel pad. The heating sheet is arranged on the thermal insulation sheet. The working plate has an inverted “U” shape, and cooperates with the base to sandwich the heating sheet, the thermal insulation sheet and the silica gel pad between the working plate and the base. The heating sheet is attached and matches a bottom surface of the working plate. The heating element separates a frame and a working plate into two devices, and provides a good contact between a heating sheet and the working plate so as to be isolated from the frame. The heating sheet immediately conducts heat to the working plate, and rapidly raises the temperature of the working plate, thereby enhancing a heating rate.

What is claimed is: 
     
         1 . A hair straightener heating element, comprising a base, a working plate, a heating sheet, a thermal insulation sheet, and a silica gel pad; wherein the base is provided with an accommodation groove, the silica gel pad is disposed inside the accommodation groove, the thermal insulation sheet is fitted to the silica gel pad, the heating sheet is disposed on the thermal insulation sheet, the working plate has an inverted U shape and cooperates with the base to sandwich the heating sheet, the thermal insulation sheet, and the silica gel pad in between, and the heating sheet is attached and matches a bottom surface of the working plate. 
     
     
         2 . A hair straightener heating element, comprising a base, a working plate, a heating sheet, and a thermal insulation sheet; wherein the thermal insulation sheet is fitted to the base, the heating sheet is disposed on the thermal insulation sheet, the working plate cooperates with the base to sandwich the thermal insulation sheet and the heating sheet in between, and the heating sheet is attached and matches a bottom surface of the working plate. 
     
     
         3 . A hair straightener heating element, comprising the working plate, an outer fixture, a base, a silica gel pad, a heating sheet, and a thermal insulation sheet; wherein the base is fixed inside the outer fixture, the silica gel pad is disposed on the base, the thermal insulation sheet is disposed on the silica gel pad, the heating sheet is disposed on the thermal insulation sheet, the working plate is fitted inside the outer fixture with the upper surface of the working plate aligned with the upper surface of the outer fixture, the working plate cooperates with the base to sandwich the silica gel pad, the heating sheet, and the thermal insulation sheet in between, and the heating sheet is attached and matches a bottom surface of the working plate.
