a motor. A rotating shaft of the motor is connected to the wind
wheel, the wind wheel and the motor are disposed in the housing, an
air inlet is disposed at the bottom of the housing, and an air
outlet is disposed on one side of the housing. As the motor
rotates, air enters the housing via the air inlet, the rotating
shaft drives the wind wheel to rotate and generate airflow in the
housing, and then the airflow is discharged via the air outlet.

shaft 4 passes through the hole and is connected to the wind wheel
2 in the housing 1.
[0041] A bottom portion of the U-shaped supporter 5 is connected to
the housing 1 via a rivet 13.
[0042] A flange 18 is extended from the cavity 9 and connected to
the edge of the bottom plate 15.
[0043] A cooling fan 10 is disposed on the rotating shaft 4 and
between the motor 3 and the housing 1, whereby improving heat
