Heating device for hair drier

Abstract

The invention discloses a heating device for a hair drier. The heating device comprises heating coils (2) and a mica plate (1); the heating coils (2) are folded into ripple shapes with the peak more than or equal to 5.0mm and are wound on the mica plate (1) alternatively by adopting a stepped, laminated and sloped arrangement manner. As the manner of deepening the ripples and arranging alternatively is adopted for the heating device for the hair drier, gaps, heat dissipation areas and windward sides among the heating coils are increased, therefore, the structure of the heating device is shortened, the cost is saved, the heat dissipation performance of the heating device is enhanced, and the phenomena that the hair driers are low in power, large in volume, overhigh in blast temperature and small in air volume, are heated to become red and cause coil collision are solved, so that the hair drier has the effects of being delicate in the product and strong in heat dissipation.

Description

technical field [0001] The invention relates to the field of hairdressing equipment, in particular to a heating device for a hair dryer. Background technique [0002] The heating device used for the existing hair dryer comprises a heating wire and a mica sheet. The general mica sheet is similar to a cylindrical shape, so that the coils wound by the heating wire are in a parallel state, and the heating wires are all in an overlapping state, so that the windward side The heat dissipation area is very small, resulting in unbalanced heat dissipation, often due to the conflict between the pursuit of product refinement and the contradiction between internal structural parts, resulting in a series of quality problems, such as small power, large volume, high air temperature, and air volume. A series of serious defects such as small size, redness, touch wire, etc. Contents of the invention [0003] (1) Technical problems to be solved [0004] The problem to be solved by the prese...
