[0034] Working Principle: In use, this invention first introduces air through the intake pipe 3, then filters it through the filter screen 8 in the processing box 1, and finally exhausts it through the outlet pipe 4. After a period of use, the filter screen needs to be disassembled and cleaned to improve subsequent filtration. When disassembling the filter screen, first remove the second fixing cylinder 147 from the limiting groove 17 and the second fixing groove 146, then remove the first fixing cylinder 145 from the second fixing groove 144, the first fixing groove 18, and the first fixing groove 143. Then, the filter screen 8 can be pulled out of the processing box 1 through the upper end of the second connecting plate 15. Simultaneously, the cleaning rollers 13 on both sides of the upper end of the filter screen 8 perform the first cleaning, scraping away impurities and dust on both sides. After removal, the filter screen 8 can be further cleaned to enhance subsequent filtration. Before cleaning and installing the filter screen 8, the controller first controls the electric telescopic rod to drive the scraper 20 to collect the impurities and dust scraped from the bottom of the processing box 1, making the dust... Dust is collected into the collection box 6 through the placement groove 11. When collecting dust, the movable plate 65 is first pulled out by the pull plate 66, so that the limiting fixing plate 67 is close to the side of the movable groove 64. The limiting fixing plate 67 can limit and fix the movable plate 65 to ensure that the movable plate 65 will not fall off. After the dust at the bottom of the treatment box 1 is collected, the movable plate 65 is fixed inside the sealing groove 63 by the pull plate 66. This can prevent the gas from being discharged from the placement groove 11 without filtration in the subsequent filtration process. After the collection box 6 is full, it can be disassembled and cleaned by the limiting device 7. When disassembling, first remove the threaded column 74 from the threaded groove 22 and the movable circular groove 73, and then remove the first limiting plate and the second limiting plate to remove the collection box 6. The impurities and dust inside the collection box 6 can then be treated. When installing the collection box 6, the operation is reversed. The connection method between the electric telescopic rod and the control button in this utility model is the prior art. The electric telescopic rod is also the prior art and will not be described in detail.
