Thick film heater structure of the electric hair curler

Abstract

The present application relates to an improved thick film stainless steel heater structure of the electric hair curler. And the technical problem the present application aims to settle is to provide a simple-structure, low-cost, fast-heating-up, insulating and high-voltage-resistant heater structure of the electric hair curler, which is more compact and stable, and has a simple production craft, a reliable performance, no lead and toxins, and a good insulating effect. Then the present application comprises a substrate equipped with a layer of an insulating thick film medium equipped with a layer of heating resistance equipped with an insulating coating layer, and the ends of the heating resistance are equipped with electrodes. For the stainless steel thick film heating component of the electric hair curler of the present application does not need printing and sintering many times and is prepared by just spraying an insulating layer on a surface of a curved stainless steel, the manufacture is easy, the power of the heater is stable, and the service life is long.
