[0006] When using a Z-shaped air duct in the present technical solution, when the fan body is working, it drives the air flow, so that the airflow flows inside the air duct body, and the electric push rod drives the connecting block to move toward the air duct body, so that the connecting pipe is separated from the seal between the air duct body and the air duct body. The staff manually rotates the screw, and the screw drives the connecting pipe to move vertically through the bearing and the slide rail, thereby achieving the purpose of lowering the use height of the fan body.

[0007] Preferably, the outer wall size of the air duct body is consistent with the outer wall size of the connecting pipe, and the air duct body is designed in an L-shape. The connecting pipe is connected to the interior of the air duct body.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention facilitates the maintenance of the fan body by arranging an electric push rod, a connecting block and a screw. When the fan body is working, it drives the air flow, thereby causing the airflow to flow inside the duct body. The electric push rod drives the connecting block to move toward the duct body, so that the connecting pipe is separated from the seal between the duct body and the duct body. The staff manually rotates the screw, and the screw drives the connecting pipe to move vertically through the bearing and the slide rail, thereby achieving the purpose of lowering the use height of the fan body, thereby facilitating the staff to maintain the fan body and improving the maintenance efficiency of the fan body.
