Description

Handheld hair dryer

Technical Field

The utility model relates to the technical field of blowers, in particular to a non-handheld blower.

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. If only a small fan rotates and the heating wire is not heated, only wind is blown out and not heated.

The hair dryer is divided into handheld hair dryer and non-handheld hair dryer, and handheld hair dryer is convenient handheld, and the product of design is all compacter, and the inside main part of hair dryer is fan and heater, because in order to pursue smallly and light, the limited serious of volume of fan and heater.

In order to achieve enough air quantity and wind power, the rotating speed of the traditional blower is increased to 1-2 ten thousand rpm, and air flow blown by the blower must pass through the heating wire, and the air flow impacts the heating wire to cause partial air flow noise, so that the blower generates about 80dB of noise. In order to achieve higher hair drying efficiency and noise reduction, the blower is then upgraded, the rotating speed is further increased to be more than 10 ten thousand rpm, and the resonance frequency is increased to be higher than the human ear-imperceptible height, so that the noise reduction effect is achieved, the blower is further developed into a high-speed blower, and the noise can become sharp and harsher because of high noise frequency of the blower. Because of the limited volume, in order to achieve higher heat conversion rate, the design density of the heating wire is higher, the noise generated by the impact of air flow on the heating wire is also increased, the noise value of the existing high-speed blower is about 65dB, and the sound is sharp and harsher.

The solution of the handheld hair dryer is to integrate the hair dryer and the bracket, the main functional module of the hair dryer is concentrated in a small space close to hair, the layout and the volume of original hair dryer components are hardly changed, larger noise still exists, and the noise value is about 80 dB.
