By installing the wind distribution assembly on the sleeve assembly, the installation cavity, the first air outlet and the first air passage are communicated in sequence. A part of the motor is located in the installation cavity and part of it passes through the outside of the wind distribution assembly. After a part of the motor passes through the first air outlet, it extends into the first air passage. When the motor starts, it can introduce external air flow from the first air inlet into the second air passage. The air flow introduced into the second air passage will continue to flow through the first air passage from the first air outlet and finally be output to the outside. Through the structural design of the wind distribution assembly and the sleeve assembly, the air flow can be effectively guided and distributed, improving the ventilation efficiency. The air flows through the second air passage of the motor, and the motor can be cooled by the air flow, improving the service life and performance of the motor. In addition, a part of the motor extends into the first air passage, further enabling the components to be compactly installed together, helping to reduce the volume and weight of the entire hair dryer and effectively improving the air outlet efficiency of the hair dryer.

The handle assembly 300 is arranged on the housing assembly 200, and the hair dryer is used by holding the handle assembly 300, making the use of the hair dryer more convenient. In addition, a control component can be installed on the handle assembly 300, so that when the user uses the hair dryer, it is convenient to control the start and stop of the motor 3 and the heating component 7 by manipulating the control component, which is convenient to use. The housing assembly 200 is provided with a second air inlet 2001. When the motor 3 starts, the outside air flow can be introduced from the second air inlet 2001 into the hair dryer air duct assembly 100 and then output to the outside, realizing the blowing function of the hair dryer. The overall structure of the hair dryer air duct assembly 100 is compact, making the ventilation efficiency of the hair dryer higher, and at the same time helping to reduce the overall volume of the hair dryer, which is convenient to carry.
