Functions Of Various Parts Of Hair Dryer

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. Wind deflector. 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 electric heating element of some hair dryers is composed of two or three sections of electric heating wire, which is used to adjust the temperature and is controlled by a selector switch.
With the reform and gradual improvement of hair dryer performance, most hair dryers at home and abroad have a set of constant-temperature automatic electronic control components connected in series to the heating elements. It can automatically connect the circuit when the hair dryer is working normally and encounter special circumstances. (such as overheating of the electric heating element, etc.), the circuit will be automatically cut off. In the selection of materials for the outer shell of the hair dryer, the use of metal (such as copper or cold-rolled iron plate) materials in the past has been changed to the use of thermoplastic engineering materials (mainly polycarbonate, modified polystyrene, modified polypropylene, etc.) become.
