[0043] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0044] Step 1: Fix the mounting plate 2 to the vent of the wall so that the vent is in communication with the inner cavity of the first ventilation duct 3. When supplying air to the clean room, start the first fan 8. Under the suction of the first fan 8, the air from the vent is transported into the second ventilation duct 5 through the first ventilation duct 3 and the connecting duct 4, and the air is discharged through one end of the second ventilation duct 5. During the transmission process, the air passes through the primary filter 62, the filter plate 12 and the filter cover 13 in sequence to filter and purify the air and prevent dust from entering the clean room.

[0045] Step 2: When cleaning the primary filter 62, the immersion water pump 66 is controlled to start. Under the suction force of the immersion water pump 66, water can be discharged into the water inlet pipe 63 through the water inlet pipe 64. The primary filter 62 is then sprayed with water through the nozzle to clean the primary filter 62, so as to clean a large amount of dust attached to one side of the primary filter 62. The dust is then allowed to flow into the sewage bucket 68 along with the water through the outlet pipe 67 and collected. By cleaning the primary filter 62, serious blockage of the primary filter 62 can be avoided, the air supply volume can be avoided, and the maintenance cost can be reduced.

[0046] Step 3: Start the first hydraulic cylinder 612. The first hydraulic cylinder 612 can pull the rack 613 downward, so that the rack 613 drives the gear 611 to rotate counterclockwise, thereby driving the rotating shaft 610 to rotate counterclockwise, so that the rotating shaft 610 drives the water spray pipe 63 to rotate counterclockwise, thereby expanding the cleaning range of the primary filter 62 and cleaning the primary filter 62 more thoroughly.

[0047] Step 4: By respectively starting the water spray pipe 63 and the heating pipe 614, the dryness and humidity of the air passing through the connecting pipe 4 can be controlled to adjust the dryness and humidity in the clean room. The ultraviolet sterilization lamp 616 can be started to sterilize and disinfect the air. The air can be further purified by passing through the activated carbon filter 617 to achieve a high degree of cleanliness.

[0048] Step 5: Press the pin 142 downward to cause the pin 142 to compress the spring 143 and move downward until the pin 142 is separated from the filter cover 13, thereby releasing the filter cover 13 from its fixed position and facilitating removal of the filter cover 13 for maintenance of the activated carbon filter 617 and one end of the second ventilation duct 5.

[0049] Step 6: When the air supply range needs to be increased, the second fan 71 is started. Under the blowing of the second fan 71, the air in the second ventilation duct 5 is separated through the connecting tube 72 and blown out to one side of the second ventilation duct 5, thereby increasing the pressure at the top end of the second ventilation duct 5, thereby increasing the air supply intensity at one end of the second ventilation duct 5 and allowing the air to be delivered farther;

[0050] Step seven: Start the second hydraulic cylinder 73. The second hydraulic cylinder 73 can push the push plate 77 to one side, so that the inner wall of the strip hole 78 pushes the strip rod 76, thereby rotating the rotating plate 75 and driving the baffle 74 to flip downward, so that the size of the air outlet on one side of the second ventilation duct 5 can be reduced by rotating the baffle 74, thereby increasing the pressure of the air at the air outlet, so that the air can be transported farther, thereby further expanding the air transportation range, which is conducive to wide promotion.
