Abstract
The utility model discloses a centrifugal fan air inlet adjustable device which comprises a machine shell, a motor, an air inlet and an air outlet, the motor is fixedly installed on the rear surface of the machine shell, the air inlet is fixedly installed on the front surface of the machine shell, the air outlet is fixedly installed on the surface of one side of the machine shell, and a rotating ring is movably arranged on the surface of the air inlet in a sleeved mode. And an adjusting plate is movably embedded in the air inlet. According to the adjustable device for the air inlet of the centrifugal fan, when the size of an air channel of the air inlet needs to be adjusted, the rotating ring is rotated, the gear ring is used for driving the gear of the air inlet to rotate when the rotating ring rotates, the adjusting plate moves up and down under the cooperation of the gear and the gear ring, and therefore the air inlet of the centrifugal fan is adjusted. When the centrifugal fan is used, the adjusting plate moving up and down is matched with the check block of the air inlet, the size of an air channel of the air inlet can be adjusted, and therefore when the centrifugal fan is used, the air inlet amount can be adjusted according to needs.
