[0035] During operation, when the rotary dehumidifier is used, in order to ensure the normal operation of the rotary dehumidifier, a filter screen is usually set at the processing air inlet 11 and the regeneration air inlet 13. After the filter screen has been used for a period of time, the filter screen will be disassembled and cleaned, which requires shutdown, resulting in low cleaning efficiency and affecting the operation of the rotary dehumidifier. When the dehumidifier is in use, the surrounding environment is inevitably humid. Therefore, when the air humidity is high, the dust on the filter screen is wet and sticky, and there is a problem of difficulty in cleaning; therefore, an air flow filter unit 2 is set at the processing air inlet 11 and the regeneration air inlet 13, and the air flow filter unit 2 includes a No. 1 filter screen 23.

Similarly, when another No. 1 filter 23 needs to be cleaned, the No. 1 electromagnet 26 is energized, and the No. 1 filter 23 is switched again and then cleaned.

When the water is released, the No. 2 electromagnet 81 is energized, and the No. 2 electromagnet 81 can attract the No. 2 block 82, so the No. 2 spring 83 contracts, driving the I-shaped rod 84 to move toward the No. 1 telescopic rod 33, that is, the No. 1 block 7 It is fixedly connected to the No. 1 telescopic rod 33. When the No. 1 telescopic rod 33 is extended or retracted, the No. 1 piston 72 also moves back and forth in the No. 1 tube 32. Due to the arrangement of the No. 1 non-return valve 73 and the No. 2 non-return valve 74, the connecting pipe 75 continuously supplies water to the No. 1 box 21. Since the other end of the connecting pipe 75 branches into the No. 1 brush body 3 and is connected to each No. 1 channel 5, the clean water can also be sprayed directly towards the No. 1 filter screen 23 when entering the No. 1 box 21, further strengthening the cleaning of the No. 1 filter screen 23; of course, under normal circumstances, the No. 2 electromagnet 81 is powered off, the I-shaped rod 84 squeezes the inner wall of the No. 1 tube 32, the No. 1 block 7 is fixed to the No. 1 tube 32, and the extension and retraction of the No. 1 telescopic rod 33 does not affect the No. 1 block 7; the water inlet pipe 61 is connected to the water tank.
