Abstract
A hair dryer includes a housing having an air inlet, an air outlet, a motor, an impeller having a plurality of blades, and a heating device. A motor fixing seat is mounted in the housing for securing the motor. The motor and the motor fixing seat are fixed in a distal end of an inner wall of the housing and located adjacent to the air inlet, and the impeller is located between the motor and the heating device. Thus, the motor only need to produce a much smaller pressure of air flow, so that the pressure of the air flow exerted on the impeller is very small, thereby producing a much smaller shear stress on the impeller, and thereby causing smaller noise.
