rod 47 drives the first deflection rod 46 to rotate, the rotation of the first deflection rod 46 drives the cross rod 45 to move upwards, the cross rod 45 moves upwards from the bottom of the linear groove of the limit groove 42, meanwhile, the limit rod 43 is positioned above the cross rod 45 in the limit groove 42 and moves upwards along the linear groove until moving to the top of the linear groove, at the moment, the first deflection rod 46 continuously rotates, the limit rod 43 acts as a rotating fulcrum at the moment, the cross rod 45 rotates along the curved groove section of the limit groove 42 to drive the locating plate 44 to rotate, the rotation of the positioning plate 44 drives the cover plate 3 to rotate, so that the cover plate 3 is positioned outside the box body 1 and does not cover the air outlet 2, the rotation of the round rod 48 drives the second gear 14 to rotate, the rotation of the second gear 14 drives the first gear 13 to rotate, the rotation of the first gear 13 drives the rotation shaft 10 to rotate, one end of the ejector rod 15 away from the fixed plate 92 is abutted with the height of the chute 171 formed by the limiting plate 17 in the initial state, at the moment, the ejector rod 15 drives the moving plate 93, the connecting rod 95 and the cleaning pad 94 to move towards the direction close to the air outlet plate 11, the cleaning pad 94 is tightly attached to the surface of the air outlet plate 11, the first spring 16 is in a compressed state, the rotation of the rotation shaft 10 drives the moving block 91 and the fixing plate 92 to move, the ejector rod 15 is always abutted with the height of the chute 171, the cleaning pad 94 is always kept in close contact with the air outlet plate 11 to move along the air outlet plate 11, when the ejector rod 15 is moved to one side wall of the box body 1 along the sliding groove 103, the cleaning pad 94 exceeds the range of the groove 922, if the movement is continued, the cleaning pad 94 collides with the moving groove 102, the fixing plate 92 cannot enter into the space of the side wall of the box body 1 along the moving groove 102, the fixing plate 92 is positioned at two sides of the air outlet plate 11, the air outlet plate 11 cannot be normally opened, when the ejector rod 15 moves to the side wall of the box body 1 along the sliding groove 103, the chute 171 formed by the limiting rod 43 also reaches the junction between the low position and the high position, the ejector rod 15 is abutted against the low position of the chute 171, at the moment, the first spring 16 drives the moving plate 93 to move away from the air outlet plate 11, so as to drive the cleaning pad 94 to return to the groove 922, the fixed plate 92 can smoothly enter the side wall of the box body 1 through the moving groove 102, meanwhile, the fixed plate 92 continuously moves after moving to the side wall space of the box body 1 along the moving groove 102, at the moment, the second rack 22 arranged on the fixed plate 92 is meshed with the fourth gear 21 to drive the fourth gear 21 to rotate, the rotation of the fourth gear 21 drives the vertical rod 20 to rotate, and because the vertical rod 20 is in threaded fit connection with the first rack 19, the rotation of the vertical rod 20 drives the first rack 19 to move downwards to drive the third gear 18 to rotate, so that the air outlet plate 11 is switched from closed to open, after the fixed plate 92 drives the second rack 22 to enter the side wall space of the box body 1 along the moving groove 102, the second rack 22 is meshed with the fourth gear 21 to drive the fourth gear 21 to rotate, the fourth rotation finally drives the rotating rod 12 to rotate, the rotation of the rotating rod 12 drives the rotating ring 25 and the protruding block 26 to rotate in the rotating groove 105, the convex blocks 26 are respectively abutted with the push rods 27 at two sides in the rotating process so as to drive the push rods 27 to move in the direction away from the rotating rod 12, the pushing movement drives the baffle plate 23 to move so as to block the moving groove 102, at the moment, the second spring 24 is in a stretching state, after the air conditioner is used, the round rod 48 is reversely rotated, the second gear 14 is driven to rotate by the rotation of the round rod 48, the first gear 13 and the rotating shaft 10 are driven to rotate by the rotation of the second gear 14, the reverse rotation moving block 91 of the rotating shaft 10 moves in the direction approaching to each other from the side wall space of the box body 1, the fixed plate 92 and the second rack 22 are driven to move by the movement of the moving block 91, the second rack 22 moves to drive the fourth gear 21 to rotate reversely, so that the first rack 19 moves upwards to drive the third gear 18 to rotate reversely, so that the rotating rod 12 rotates reversely, the rotating rod 12 rotates reversely to drive the air outlet plate 11 to be converted into a closed state from an open state, the rotating rod 12 also drives the rotating ring 25 and the protruding block 26 to rotate, the pushing rod 27 loses contact due to the reverse rotation of the protruding block 26, the baffle 23 is driven to return to the accommodating groove 104 under the action of the second spring 24, the fixing plate 92 can move out of the inner wall space of the box body 1 along the moving groove 102, the cleaning pad 94 is driven to be closely attached with the air outlet plate 11 under the contact action of the chute 171, the air outlet plate 11 can be cleaned again.
