In this embodiment, the blower is mainly used for air drying hair and clothes. In other embodiments, the application scenario of the blowing device is not specifically limited.

Please refer to FIG. 29 , FIG. 30 and FIG. 31 , the handle device 410 includes a handle housing 411 and an airflow generator 412 . Wherein, the handle housing 411 has an accommodating cavity 4111 and an air inlet 4112 and an air outlet 4113 communicating with the accommodating cavity 4111, and an airflow generating part 412 is arranged in the accommodating cavity 4111, and the airflow generating part 412 is suitable for generating negative pressure to The fluid enters the accommodating cavity 4111 from the air inlet 4112, flows out from the air outlet 4113 to the outside of the handle housing 411, and then enters the air cylinder device 420 of the hair blowing device, so that the air cylinder device 420 can heat the fluid or Squirt directly.

In this embodiment, the ratio of the area of the air outlet 4113 to the area of the air outlet end of the airflow generating element 412 is less than or equal to 1.5-2.2, preferably 2. This setting can make the width of the flow path of the fluid in the accommodating cavity 4111, that is, the air outlet 4113 of the handle housing 411 is reduced relative to the air inlet end of the airflow generating part 412, which has a certain effect of gathering wind, thereby reducing the flow of the fluid. The flow resistance enables the fluid to quickly pass through the inside of the handle housing 411 to increase the air outlet efficiency. As an option, the width (that is, the lateral dimension) of the flow path of the fluid inside the handle housing 411 can be gradually reduced, which can achieve a better effect of collecting wind.

Specifically, the airflow generating element 412 includes a motor 4121 and an impeller 4122 that is shaft-connected to the motor 4121 of the motor 4121 . The impeller 4122 is arranged at the air inlet end, and can rotate under the driving force of the motor 4121 to drive the airflow around the impeller 4122 to accelerate the flow, thereby increasing the pressure of the surrounding airflow to enable the airflow to move in a directional manner, so that the airflow generating part 412 can transfer the fluid It enters into the accommodating cavity 4111 from the air inlet 4112 , and flows out from the air outlet 4113 to the outside of the handle housing 411 .

Referring to FIG. 31 and FIG. 33 , the airflow generating element 412 further includes a protective sleeve 4123 , and the protective sleeve 4123 includes a first annular sleeve 41231 .
