Description

Noise-reducing electric hair drier

Technical Field

The utility model relates to the technical field of electric hair dryers, in particular to a noise-reduction electric hair dryer.

Background

The blower is composed of a group of electric heating wires and a small fan with high rotation speed. When the electric heating wire is electrified, heat is generated by the electric heating wire, and the air blown by the fan is changed into hot air through the electric heating wire. The hair dryer is mainly used for drying and shaping hair, but can also be used for local drying, heating and physiotherapy in the aspects of laboratories, physiotherapy rooms, industrial production, artists and the like. The resistance wire of the electric hair drier is spirally wound on the insulating sheet of the air outlet, and the fan is positioned between the resistance wire and the driving motor. And the volume of the fan is larger than the diameter of the air outlet. Thus, strong wind power generated by the fan can generate great flow velocity in a narrow air outlet, and high-speed air flow is blocked by the resistance wire to generate great noise.
