BLDC hair dryer manufacturer.Main components of hair dryer

　　Although there are many types of hair dryers, their structures are similar and similar. They are all composed of a shell, a handle, a physical electric motor, a fan blade, an electric heating element, a wind deflector, a switch, a power cord, and so on. The functions of each part of the hair dryer:

　　housing

　　It plays a protective role on internal components and is also an external decorative component.

　　Electric motor and fan blades

　　The motor is installed inside the casing, and the fan blades are installed on the shaft end of the motor. When the motor rotates, air is drawn in from the air inlet and blown out from the air outlet.

　　Electric heating element

　　The electric heating element of a hair dryer is wound with an electric heating wire and installed at the air outlet of the hair dryer. The air discharged by the motor is heated by the electric heating wire at the air outlet and converted into hot air to be sent out. Some hair dryers are equipped with thermostats near the heating elements, which cut off the circuit when the temperature exceeds the predetermined temperature to provide protection. Wind deflector

　　Some hair dryers have circular windshields at the air inlet to regulate the air intake. A hair dryer without a circular wind deflector can also adjust the air intake by covering a part of the air intake with a piece of paper. When the air intake is low, the air blown out is relatively hot, while when the air intake is high, the air blown out is not too hot. Please note that the air outlet should not be blocked too much, otherwise it may damage the motor or burn out the electric heating element due to excessive temperature.

　　switch

　　The hair dryer switch generally has three positions: "hot air", "cold air", and "stop". It is commonly used to indicate "stop" in white, "hot air" in red, and "cold air" in blue.

　　Some electric hair dryers have electric heating elements composed of two or three sections of electric heating wires, which are used to adjust the temperature and controlled by a selector switch.

　　Working principle: When the power is turned on, the motor drives the fan blades to rotate and sucks air in from the air inlet. After a simple working circuit principle, the working circuit principle is simple

　　Electric heating element heating,

　　After forming hot air, it blows out from the air outlet. Electric hair dryers usually adjust the temperature of the air supply by controlling the power on and off of the electric heating elements. When all the electric heating elements are powered on for heating, the hot air is blown out; When all the electric heating elements are powered off, cold air is blown out. The speed of the fan blades determines the air output, which is generally adjusted in two gears: soft wind and fast wind
