1. Shell. It protects internal parts and is also an external decorative part.

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

3. Electric heating element. The electric heating element of the hair dryer is made of electric heating wire and is installed at the air outlet of the hair dryer. The wind discharged by the motor is heated by the electric heating wire at the air outlet and becomes hot air and is sent out. Some hair dryers are equipped with a thermostat near the electric heating element. When the temperature exceeds a predetermined temperature, the circuit is cut off for protection.

4. Windshield. Some hair dryers have a circular windshield at the air inlet to adjust the air inlet volume. For hair dryers without a circular windshield, you can cover part of the air inlet with a piece of paper to adjust the air inlet volume.

If the air intake volume is small, the air blown out will be hotter; if the air intake volume is large, the air blown out will not be too hot. It should be noted that the air outlet cannot be blocked too much, otherwise the motor will be damaged or the heating element will be burned out due to excessive temperature.

5. Switch. Hair dryer switches generally have three positions: "hot air", "cold air", and "stop". White is commonly used to indicate "stop", red indicates "hot air", and blue indicates "cold air".

The hair dryer has no asbestos in its structure. Because asbestos fibers can cause diseases such as asbestosis and pleural mesothelioma, many countries have chosen to completely ban the use of this dangerous substance.

Working principle:

The hair dryer directly relies on the motor to drive the rotor to drive the fan blades to rotate. When the fan blades rotate, air is sucked in from the air inlet. The resulting centrifugal airflow is blown out from the front nozzle of the air dryer.

When the air passes through, if the heating wire on the heating bracket installed in the air nozzle is energized and heated, hot air will be blown out; if the selector switch does not enable the heating wire to be energized and heated, cold air will be blown out. . This is where the hair dryer is used for drying and shaping purposes.

The selector switch on the handle of the hair dryer is generally divided into three positions, namely, off position, cold air position, and hot air position, and is accompanied by indicator plates in white, blue, and red colors. Some hair dryers are also equipped with a motor speed control switch on the handle, which can be used to select the air volume and hot air temperature.

The back or side of the casing of various hair dryers is equipped with a rotatable circular air-adjusting hood. By rotating the hood to adjust the cross-section size of the air inlet, the delivered wind speed and the temperature of the hot air can be adjusted.
