A connecting plate 903 is fixedly connected to the surface of one end of the telescopic rod 902 close to the rotating drum 8, and the bearing plate 901 can support the telescopic rod 902.

[0030] Two sets of connecting rods 904 are hinged on the surface of one side of the connecting plate 903 away from the telescopic rod 902. The two sets of connecting rods 904 are symmetrically arranged with the center line of the connecting plate 903 as the symmetry axis. The ends of the two sets of connecting rods 904 away from the connecting plate 903 are hinged with clutch blocks 905. The outside of the two sets of clutch blocks 905 is provided with a rectangular frame 906. The two side surfaces of the rectangular frame 906 are provided with sliding holes adapted to the clutch blocks 905.

After cleaning, release the lever 909 to make the two clutch blocks 905 automatically disengage from the rotating drum 8, and the cleaning brush plates 1006 will automatically stop brushing.

[0035] In the present invention, when the fan 2 is started to rotate, the rotating rod 4 can be driven to rotate, and then the driven rod 6 can be driven to rotate synchronously through the synchronous belt 7, and then the rotating drum 8 can be driven to rotate. When the filter screen 3 is blocked by impurities such as dust, it is only necessary to manually slide the lever 909 along the rectangular groove 910 on the box body 1, and then cooperate with the bearing rod 911 in the box body 1 to make the lever 909 rotate, thereby driving the slider 908 to push the connecting plate 903 on the telescopic rod 902, pushing the telescopic rod 902 to extend in the direction of the rotating drum 8, and then the connecting plate 903 can make the two clutch blocks 905 slide out straight away from each other from the rectangular frame 906 through the two connecting rods 904. Until it comes into conflict with the anti-slip groove of the rotating drum 8, the clutch block 905, the rectangular frame 906, the connecting rod 904, the connecting plate 903, and the telescopic rod 902 can be rotated together with the driven rod 6. At the same time, when the telescopic rod 902 rotates, it will drive the half gear 1001 to rotate at the same time, and then engage with the tooth groove 1003 on the inner wall of the external bar frame 1002. The L-shaped guide plate 1004 is guided by the sliding groove on the box body 1, so that the bar frame 1002 can perform reciprocating linear motion, thereby driving the three sets of cleaning brush plates 1006 through the vertical plate 1005 to automatically clean the dust on the surface of the filter screen 3, without manual cleaning, and the operation is simple and quick.
