[0012] Beneficial effects

[0013] The utility model provides a hair dryer motor with a noise reduction structure. Compared with the prior art, it has the following beneficial effects:

[0014] For the hair dryer motor with the noise reduction structure, by setting a diversion plate, a noise reduction cover and a sound insulation board, etc., and using the connection between the fixing plate and the hair dryer housing, the installation and fixation of the motor are realized. When the motor body drives the blade to rotate, the generated air flow enters through the noise reduction cover, which is convenient for noise reduction protection of the air inlet. The sound absorption board can eliminate noise. At the same time, round holes are opened on the noise reduction cover, so it has a certain noise reduction function, realizing double protection. And after the air flow enters the motor cover, it is guided by multiple diversion plates, so that the air flow forms a certain swirl in the motor cover, reducing the impact noise, and using the sound insulation board to protect the motor cover to prevent the noise of the motor from being transmitted outward, reducing the noise pollution during the use of the hair dryer.
