Background
Current hair curlers consist of two parts: a handle and a heating tube. The handle is made of engineering plastics, the heating tube is provided with a spring clamp, and the heating tube consists of a hollow metal tube and a heating body filled in the hollow metal tube. The heating body starts to heat after being electrified, so that the surface of the heating tube reaches a high temperature of more than 200 ℃, hair is wound on the heating tube and clamped by the spring clamp, and keratin in the hair is denatured under the action of the high temperature, so that hair curling and shaping are realized. Belongs to heat setting.
The hair curlers of today have the following disadvantages:
1. the heating tube is at high temperature of 200 ℃ and is unavoidable and unhealthy for hair scalding;
2. the hair is wound on the heating tube manually in turn, and the hair can be shaped after the keratin in the hair is denatured by heating for a period of time, so that the repeated and tedious process needs to consume a great deal of time and physical strength of a user, is easy to fatigue the user, has low efficiency and is not humanized;
3. because the hair is wound on the metal heating tube, the heating tube is exposed for convenient operation, so that scalding cannot be prevented, the possibility of scalding hands and faces exists for a user, and the hair is unsafe;
4. spring clips for fixing hair sometimes leave creases in the hair, which can cause damage to the hair and are unsightly;
5. in order to maintain the high temperature of the heating tube, a large amount of electric energy is consumed, and the environment is not protected.
