Background technique

The hair curler is a handheld electronic product used to perm the hair. Its main components are a handle and a heating curling rod. The temperature is controlled by a circuit. The heating rod is generally composed of metal materials. The commonly used metal materials are iron pipes or aluminum pipes. A heating element is implanted inside the metal pipe. Through the control of the circuit, the heating element can be heated to 200-220°; while the traditional curling iron is greatly affected by the environment due to the exposure of the heating element. The temperature of the curling iron is difficult to control, so that the hair is not heated evenly, the molding speed is slow, the durability of the shape is not long, the hairstyle effect is not natural, and the heating device is exposed outside, when it is used by hand, it is easy to cause accidents to the human body and its In addition, traditional automatic hair curlers generally use three-phase DC brushless motors, and DC brushless motors use sensors and electronic commutators built in the motor. The control part is complex and reliability is concerned. still relatively low.
