[0002] A hair curler is a high-temperature electronic product used for curling hair. It mainly conducts heat to the surface of a tube body through a heating element, and the surface temperature is generally set to a certain temperature. After reaching a certain temperature through this heat, the hair curler curls the hair. Traditional hair curlers do not have the function of automatic curling. When in use, it often requires the user to wind the hair strand by strand around the heating tube body, which is rather laborious. And when perming the hair by oneself, it is even more troublesome. The use of the hair curler is not convenient enough, so the curling effect cannot be achieved well.

[0003] With the progress of technology, hair curlers with automatic curling functions have emerged. At the same time, to avoid the curling component scalding the human skin during use, a protective cover is generally provided on the outside of the curling component. For example, an automatic hair curler disclosed in a Chinese utility model patent (Publication No.: CN219020443U) includes a handle, a heating element, and a rotating member. The rotating member is arranged on the periphery of the heating element. A circuit board and a driving device for driving the rotating member to rotate around the heating element are provided in the handle. A power switch is provided on the handle.
