Hair dryer for travel use manufacture

　　Composition of hair dryer

　　A hair dryer mainly consists of the following parts:

　　Shell: The shell of a hair dryer is usually made of plastic or metal, which serves to protect internal components and enhance aesthetics. The shell usually has air inlet and outlet, as well as various control switches and indicator lights.

　　Electric motor: The electric motor is the core component of a hair dryer, which drives the fan blades to generate airflow through rotation. The power of the electric motor determines the wind speed and intensity of the hair dryer.

　　Fan blades: Fan blades are installed on the shaft of the electric motor and rotate at high speed with the rotation of the motor, sucking air into the blower and accelerating it out.

　　Heating element: The heating element is usually composed of resistance wires and is located in the air duct of the hair dryer. When current passes through a resistance wire, the wire will generate heat, heating up the surrounding air and producing hot air.

　　Control switch: The control switch is used to adjust the wind speed and temperature of the hair dryer. Common control switches include wind speed adjustment switch, temperature adjustment switch, and power switch.

　　Power cord: The power cord is used to connect the hair dryer to a power outlet, providing power to the hair dryer.

　　In addition, some high-end hair dryers may also be equipped with other functional components such as negative ion generators, infrared emitters, etc., which can provide additional care and protection for hair.
