Detailed Description

Referring to fig. 1 and 2, a first preferred embodiment of the present invention is shown, which comprises an outer casing 10, a motor 20 and an impeller 30.

The outer shell 10 comprises a left shell 11 and a right shell 12, the left shell 11 and the right shell 12 are spliced and fixed by ultrasonic welding without using a screw, a mounting cavity 101 and an air cavity 102 are formed by enclosing the left shell 11 and the right shell 12, an air inlet 103 and an air outlet 104 are formed in the outer shell 10, and the air inlet 103 and the air outlet 104 are both communicated with the air cavity 102; in this embodiment, the outer casing 10 is made of plastic, the air inlet 103 and the air outlet 104 are both formed by enclosing a left casing 11 and a right casing 12, and fixing posts 105 extend from inner walls of the left casing 11 and the right casing 12.

The motor 20 is clamped and fixed between the left shell 11 and the right shell 12, and the motor 20 is positioned in the mounting cavity 101; the peripheral side of the motor 20 has a heat dissipation hole 21, and the fixing post 105 is inserted into the heat dissipation hole 21 for fixing.

The impeller 30 is fixed on the output shaft 22 of the motor 20 and is driven by the motor 20 to rotate, the impeller 30 is located in the air cavity 102, in this embodiment, the air inlet 103 faces the impeller 30, and the air outlet 104 is located at the periphery of the impeller 30.
