step two: when the ventilator needs to be cleaned after being used for a period of time, the electric telescopic rod (14) is firstly opened, the output end of the electric telescopic rod (14) extends out, and the arc-shaped cleaning brush (22) is pushed to be attached to the inner wall of the ventilation blade (3) and a gap between the two ventilation blades (3);
step three: then, a cleaning motor (8) is started, the output end of the cleaning motor (8) drives a transmission chain wheel (9) to rotate, the transmission chain wheel (9) drives a transmission chain (12) to rotate through an adjusting chain wheel (11), the transmission chain (12) drives a limiting block (19) to move from top to bottom, the limiting block (19) drives a sleeve (17) to move downwards through pressing a limiting plate (18), and the sleeve (17) extrudes a return spring (20) to deform;
step four: the sleeve (17) moves to drive the spring telescopic rod (15) to extrude and contract firstly, then the spring telescopic rod (15) is restored to deform in the process, the connecting rotary drum (13) is driven to rotate, the connecting rotary drum (13) drives the electric telescopic rod (14) to swing by less than ninety degrees, the electric telescopic rod (14) drives the arc-shaped cleaning brush (22) to clean a gap between the two ventilation blades (3) and the ventilation blades (3), and dust and attachments on the ventilation blades (3) are removed;
step five: the adjusting chain wheel (11) enables the lower end of the transmission chain (12) to be expanded, the limiting block (19) moves downwards while moving towards the edge of the limiting plate (18) in the process that the limiting block (19) gradually approaches the adjusting chain wheel (11) until the limiting block (19) releases the pressing on the limiting plate (18), the limiting plate (18) and the sleeve (17) are reset under the restoring force action of the reset spring (20), the arc-shaped cleaning brush (22) is reset along with the limiting block, and after the transmission chain (12) drives the limiting block (19) to move above the limiting plate (18) again, the limiting block (19) can drive the limiting plate (18) to move downwards again, so that the arc-shaped cleaning brush (22) can continuously move up and down to clean the ventilating vanes (3);
step six: after the cleaning work is finished, the cleaning motor (8) is closed, the sleeve (17) is kept at the upper end of the connecting main rod (4) under the restoring force action of the return spring (20), the electric telescopic rod (14) is controlled to return, and the arc-shaped cleaning brush (22) is driven to be far away from the ventilation blade (3) so as to treat the next cleaning work.
