when the wind speed is suddenly increased in use, the pressure generated by the air flow blows the filter screen (2) to move, when the filter screen (2) moves, the convenience of the filter screen (2) in moving can be improved by virtue of the first guide roller (12) and the second guide roller (13), meanwhile, the second stay rope (5) is driven to move by virtue of the filter screen (2), and the second stay rope (5) drives the blade (3) to swing by virtue of sliding contact between the second stay rope (5) and the guide pulley (7), so that the blade (3) swings upwards to be in a closed state, and damage to indoor articles caused by the increase of the wind speed is prevented;
the filter screen (2) drives the first guide roller (12) and the second guide roller (13) to rotate when moving, the second one-way bearing (11) is driven to rotate by the first guide roller (12) and the second guide roller (13), when the second one-way bearing (11) rotates, the rotating shaft (10) is driven to rotate in the first one-way bearing (9), the winding tube (14) is driven to move when the rotating shaft (10) moves, the third pull rope (22) is driven to move by the winding tube (14), the third pull rope (22) is wound on the winding tube (14), when the third pull rope (22) moves, the square frame (21) is driven to move upwards by the movement of the third pull rope (22), and the surface of the filter screen (2) is cleaned by the cleaning brush (23) in the square frame (21), and meanwhile, the guide wheel (24) is contacted with the filter screen (2) by the action of the guide wheel (24), so that the cleaning effect of the cleaning brush (23) is improved;
the rolling balls (19) arranged in the annular baffle ring (15) are in rolling contact with the slotted holes (20), and when the rolling balls (19) are in rolling contact with the slotted holes (20), the rolling balls (19) squeeze the second springs (18), and when the annular baffle ring (15) is not moving, the rolling balls (19) are positioned in the slotted holes (20) under the reset action of the second springs (18), so that the rolling balls (19) are prevented from moving, and the annular baffle ring (15) is fixed;
when the square frame (21) is pulled up to the limit, the rotating shaft (10) is driven to rotate continuously so that the ball (19) and the slot hole (20) are separated, at the moment, under the restoring force of the spring (16), the winding tube (14) can be quickly reversed, so that the third pull rope (22) is released, the cleaning structure is automatically moved downwards under the gravity to reset for convenient subsequent use, after the spring (16) is restored, the ball (19) can be clamped into the slot hole (20) again, so that the winding tube (14) and the rotating shaft (10) are kept stable again, and meanwhile, the ball (19) and the slot hole (20) are restored to the initial state;
when the wind speed is smaller, the second stay cord (5) is driven to move by virtue of the reset action of the first spring (6), and the blades (3) are enabled to swing downwards through the second stay cord (5), so that the inclination angle of the blades (3) is adjusted, the size of an air inlet in the frame body (1) is reduced, and the air inlet in the frame body (1) is reduced; and when no wind exists, the second pull rope (5) can be reset by the reset effect of the first spring (6), so that the blade (3) is restored to the initial state.
