About the knowledge of the hair dryer, introduced the structure of the hair dryer, mainly composed of mica sheet, electric heating element, motor, blade, shell, switch, handle and other parts, with the motor, electric heating element as the main components, the following to understand. The hair dryer is composed of mica sheet, electric heating element, motor, blade, shell, switch, handle and other parts.
The hair dryer is mainly composed of a shell, a motor, a blade and a heating element.
1, shell
The shell of the hair dryer is the structure protection layer, but also the appearance of the parts, the requirements of beautiful shape, light weight, generally made of metal sheet after the surface of chrome plating or engineering plastic pressing.
2, motor
Permanent magnet motor and series motor with high speed, mostly used for axial flow hair dryer; The induction motor has low speed and is mostly used for centrifugal hair dryer.
3, the blades
Generally made of sheet metal or plastic, it is required to have large air volume, high efficiency and small wind damage.
4. Electric heating element
Generally with nickel chromium wire wrapped in porcelain or mica bracket, most of the electric heating elements are equipped with overheating protection device, and can adjust the heating temperature.
The new type of hair dryer generally uses PTC element as electric heating element, itself has overheating protection function.
