Description

Hair straightener with heating plate capable of being elastically bent and deformed

Technical Field

The invention relates to the technical field of beauty and hairdressing tools, in particular to a hair straightener.

Background

The hair straightener has wide application in the hairdressing industry and can be used for straightening hair. Since the heating plate of the existing hair straightener is usually made of rigid materials such as rigid metal, ceramic or a combination of the two, a rigid structure is formed. Sometimes, a spring or silica gel is arranged in the shell and used for supporting the bottom of the heating plate assembly, so that the heating plate assembly can move up and down or swing integrally when being stressed, but the whole heating plate is of a rigid structure, so that the clamping pressure of the hair straightener can not be too large when the puller pulls hair, and the situation that the hair is clamped and can not slide due to the large clamping pressure is avoided, and the user feels pain is caused. Simultaneously, the rigid board that generates heat can disperse the hair centre gripping when the centre gripping is pulled the hair, can not wrap up well, leads to the heat of the board that generates heat can not evenly transmit for the hair fast, causes to pull the efficiency reduction of sending out, and the effect is not good. Although some people try to design the heating plate into a deformable body, the pain feeling can be reduced to a certain degree, but the heating plate cannot generate controllable deformation matched with the hair pulling direction according to the hair pressure when the hair is pulled, so that the problems of poor wrapping performance and poor hair pulling effect on the hair cannot be solved.
