Hair dryer (hair dryer) is a haircut tool invented at the end of 19. Modern hair dryer is a mechanical device, which speeds up the airflow by electric means, thus generating wind power and raising the air temperature. Hair dryers are mainly used for hair drying and styling, but they can also be used for local drying, heating and physical therapy in laboratories, physical therapy rooms, industrial production and artistic design.
According to the type of motor used, it can be divided into AC series excitation type, AC shielded pole type and DC permanent magnet type. Series-excited hair dryer has the advantages of large starting torque and high rotating speed, and is suitable for manufacturing high-power hair dryers. The disadvantage is that the noise is high, and the commutator has certain interference to telecommunication equipment.
The advantages of the hood-pole blower are low noise, long service life and no interference with telecommunication equipment, while the disadvantages are low rotating speed, poor starting performance and heavy weight. The advantages of permanent magnet hair dryer are light weight, high rotating speed, simple manufacturing process, low cost, good quality and low price.
