Hair dryer structure

.
The working principle of hair dryer: hair dryer is directly driven by the motor to drive the rotor to drive the rotation of the wind blade.During the rotation of the air blades, air is drawn in through the air inlet and the centrifugal airflow formed is blown out of the front nozzle of the air cylinder.The heating wire is energized to become hot, and when the air passes through the heating wire on the heating bracket installed in the air nozzle, it blows out hot air; if you choose the heating wire is not energized to heat, it blows out cold air.In this way to achieve the purpose of drying.
