The cooled clean air passes through the drying filter element 7 to remove droplets and water vapor, and then the dry clean air is blown into the integrated distribution box through the connecting tube 8 for cooling operation. Through the above arrangement, it is convenient to effectively cool down the drawn external air and filter dust particles and droplets and water vapor, which can effectively ensure the cleanliness and dryness of the drawn air, thereby effectively avoiding the inside of the integrated distribution box When the dust filter 6 and the drying filter 7 need to be replaced, the corresponding rotating rod 19 is rotated first, and the rotating rod 19 drives the second bevel gear 20 to rotate, and the second bevel gear 20 drives the first bevel gear 18 to rotate, and the first bevel gear 18 drives the two-way screw rod 17 to rotate, and the two-way screw rod 17 drives the two slide bars 16 to slide in the chamber 15 and approach each other, and the slide bar 16 drives the clamping rod 14 to slide out of the corresponding clamping hole 13, so that the fixation of the cover plate 5 is released, and then the cover plate 5 is pulled out, so that the U-shaped frame 4 is driven to slide out of the second box body 2, so that the dust filter 6 or the drying filter 7 is taken out, and then it can be replaced. Through the above arrangement, the dust filter 6 and the drying filter 7 are quickly installed and disassembled, so that the dust filter 6 and the drying filter 7 are easily replaced, thereby ensuring the cleaning effect of dust and moisture in the external air.
