When the air flows through the evaporator 24, the water vapor therein is cooled and reaches the saturation temperature and condenses into water droplets. At the same time, the first power component causes the pull rod 4 to pull the connecting plate 2 to move downward, and the spring 3 contracts, thereby causing the first connecting frame 22 and the second connecting frame 23 to drive the first brush 29 and the second brush 30 to move downward, so that the first brush 29 and the second brush 30 clean the water droplets on the evaporator 24 pipe and make the water droplets fall into the collection box 16.

[0031] In the present invention, it should be noted that two baffle rods 13 are rotatably connected to the outer wall of one side of the ventilation pipe 1, the rotation axis of the baffle rod 13 is in its middle position, and the top end of the baffle rod 13 is in contact with the collection box 16, and the bottom end of the baffle rod 13 is rotatably connected to a connecting rod 14, and a second magnetic block 20 is fixed to one side of the connecting rod 14 by bolts, and a first magnetic block 19 is fixed to the outer wall of one side of the ventilation pipe 1 by bolts, and the first magnetic block 19 is in contact with the second magnetic block 20.

At this time, the position of the moving connecting rod 14 is fixed. The first power assembly includes a guide rail 6, which is fixed to the upper surface of the ventilation pipe 1 by bolts. The upper surface of the ventilation pipe 1 is fixed with a cylinder 7 by bolts. One end of the piston rod of the cylinder 7 is fixed with a connector 5 by bolts, and the connector 5 slides along the guide rail 6. The guide rail 6 can guide the connector 5 so that it can move stably in a specified direction. The pull rod 4 The connecting head 5 is rotatably connected, and the cylinder 7 contracts to move the connecting head 5 along the guide rail 6, so that the pull rod 4 pulls the connecting plate 2 downward. The second power assembly includes an electric telescopic rod 11, which is fixed to the outer wall of one side of the ventilation pipe 1 by bolts. The extended end of the electric telescopic rod 11 is fixed with a rack 9 by bolts. One end of the baffle 12 passes through the ventilation pipe 1 and is keyed to a gear 10, and the gear 10 is meshed with the rack 9. The electric telescopic rod 11 is extended and retracted to move the rack 9, thereby causing the gear 10 to rotate. A water-absorbing cloth 31 is provided inside the collection box 16, and a plurality of drainage holes 32 are provided on one side of the collection box 16. When the collection box 16 is pulled out of the slot 26, the moisture in the collection box 16 is discharged from the collecting box 16. The humidity is automatically discharged from the drain hole 32. A humidity sensor 15 is fixed to the bottom outer wall of the ventilation pipe 1 by bolts. The detection end of the humidity sensor 15 passes through the bottom of the ventilation pipe 1. The humidity sensor 15 detects the humidity of the ventilation pipe 1. An elastic plate 28 is fixed to the top inner wall of the ventilation pipe 1 by bolts, and the bottom end of the elastic plate 28 contacts the baffle 12. When the baffle 12 blocks the air inlet 8, the bottom end of the baffle 12 pushes the elastic plate 28 to generate a bending deformation. The elastic plate 28 can guide the gas in the ventilation pipe 1. A handle 18 is fixed to the outer wall of one side of the collection box 16 by bolts, which is convenient for the staff to pull the first collection box 16. The water outlet and water inlet ends at the side of the evaporator 24 pass through the ventilation pipe 1.

[0032] Working principle of this embodiment: first, the bottom of the ventilation pipe 1 is connected to the external power equipment. When the air in the housing of the power equipment needs to be dehumidified, the humidity sensor 15 detects the humidity of the ventilation pipe 1. When the detected humidity is high, the first fan 27 is started, and the electric telescopic rod 11 is started. The electric telescopic rod 11 contracts to move the rack 9, so that the gear 10 drives the baffle 12 to rotate, and then the baffle 12 blocks the air inlet 8. At the same time, the bottom end of the baffle 12 pushes the elastic plate 28 to bend and deform, and the temperature in the ventilation pipe 1 is lowered through the evaporator 24. When the air flows through the evaporator 24, the water vapor in it is cooled to After reaching the saturation temperature, water droplets are condensed and the cylinder 7 is started at the same time. The cylinder 7 contracts to move the connecting head 5 along the guide rail 6, so that the pull rod 4 pulls the connecting plate 2 downward, and the spring 3 contracts, so that the first connecting frame 22 and the second connecting frame 23 drive the first brush 29 and the second brush 30 to move downward, so that the first brush 29 and the second brush 30 clean the water droplets on the evaporator 24 pipe, and the water droplets fall into the collection box 16 for collection. Since the partition 25 divides the horizontal part of the ventilation pipe 1 into two upper and lower spaces, the gas in the ventilation pipe 1 is circulated through the first fan 27, and the gas in the casing of the power equipment is dehumidified.
