1, according to the way of use

There are hand-held and support hair dryers. The pedestal hair dryer can be placed on the table or hung on the wall, and you can blow your own hair.

2, according to the way of air supply

There are centrifugal hair dryers and axial hair dryers. The centrifugal type drives the fan blades to rotate, so that the air entering the hair dryer obtains inertial centrifugal force and continuously vents outward. Its disadvantage is that the exhausted wind does not flow through the motor, and the motor heats up. The advantage is that the noise is low. The axial flow motor drives the blades to rotate, and the air that enters the hair dryer flows axially, continuously venting outward. The advantage is that all of the discharged air flows through the motor, the motor has good cooling conditions, and the insulation is not easy to age; its disadvantage is that the noise is large.

3, according to the material used in the outer casing

There are metal hair dryers and plastic hair dryers. The metal hair dryer is rugged and can withstand higher temperatures. The plastic hair dryer has light weight and good insulation performance, but is easy to age and has poor high temperature resistance.

4, according to the structure principle

AC induction: low noise, but large size. AC series excitation: The number of revolutions is high, and the amount of air generated per unit time is also large.
