[0033] By providing the U-shaped brush 47 , the surfaces of the three valve leaves 3 can be cleaned, thereby preventing the valve leaves 3 from being affected by dust and debris contaminated after long-term use.

[0034] like Figure 2 As shown, a through groove 413 penetrating the air duct 1 is provided at the bottom of the air duct 1, and the through groove 413 is located directly below the three valve leaves 3. The left and right parts of the bottom end of the air duct 1 are fixedly connected with fixing plates 411, and the dust collecting frame 410 is clamped on the opposite surfaces of the two fixing plates 411.

[0035] By providing the dust collecting frame 410, the cleaned dust and the like can be collected uniformly, thereby preventing the dust from being discharged from the air outlet and polluting the indoor environment.

[0036] like Figure 4 As shown, the baffle structure 5 includes a mesh plate 51 , and the left and right parts of the top and the left and right parts of the bottom of the mesh plate 51 are both provided with locking holes 52 .

[0037] By providing the mesh plate 51 , the valve leaf 3 can be protected to prevent debris from passing through the mounting plate 2 and colliding with the valve leaf 3 to damage it.

[0042] The working principle of the utility model is as follows: when the ventilation and air conditioning is working, the first motor 44 is started first. Under the action of the transmission assembly 45, the first motor 44 drives the worm 43 to rotate, and then drives the three worm wheels 42 to rotate synchronously, thereby opening the three valve leaves 3. At the same time, the opening angle of the valve leaf 3 is controlled by controlling the rotation angle of the worm 43. When the valve leaf 3 is closed, the second motor 49 can be started to drive the reciprocating screw rod 48 to rotate. The rotation of the reciprocating screw rod 48 drives the U-shaped brush 47 to slide left and right, thereby achieving the cleaning effect of the valve leaf 3. The dust falls into the dust collecting frame 410, and then the dust collecting frame 410 can be removed by disassembling the buckle 412, and the dust and the like can be processed. When the grid plate 51 or the valve leaf 3 needs to be maintained, the traction rope 57 is lifted upward, and then the blocking block 56 is recovered to the inside of the blocking rod 54. At this time, the grid plate 51 can be removed. At the same time, under the action of the first elastic telescopic rod 53, the two blocking rods 54 slide to the side away from each other, and then slide to the inside of the left and right parts of the mounting plate 2, and the two ends of the outer wall of the traction rope 57 located at the upper end of the blocking rod 54 are respectively inserted into the two card grooves 58.
