A filter element 14 is disposed inside the filter housing 11. A hole is opened at the top of the filter housing 11 through which the filter element 14 can pass. The filter element 14 passes through the hole into the inside of the filter housing 11, and one end is placed at the port of the outlet pipe 12. The hole is sealed with a sealing cap, which is fixed to the top of the filter housing 11 by bolts.

[0026] The shifting assembly 2 includes a main body connecting pipe head 21 and an outer pipe connecting pipe head 22. The main body connecting pipe head 21 of the two shifting assemblies 2 is fixed to one end of the air inlet pipe 13 and the air outlet pipe 12, respectively. A flexible hose 23 or a corrugated telescopic tube is fixedly connected between the main body connecting pipe head 21 and the outer pipe connecting pipe head 22. A first mounting ring 24 is fixed on the outer surface of the main body connecting pipe head 21, and a second mounting ring 25 is fixed on the outer surface of the outer pipe connecting pipe head 22. An annular mounting groove 26 is provided on one side of the first mounting ring 24 and one side of the second mounting ring 25. A pull-out component is provided between the two annular mounting grooves 26. The pull-out component is used to pull the filter body 1 out of the installation area to prevent objects around the filter body 1 from hindering the operation of the filter body 1 during maintenance.

[0027] The pull-out component includes a connecting plate 27 and a telescopic plate 28 that rotate within two annular mounting slots 26 respectively. One end of the connecting plate 27 is fixed with a bracket plate 29 for supporting the main body connecting pipe head 21 and the filter body 1. The telescopic plate 28 is connected to the connecting plate 27 through the bracket plate 29.

[0028] The telescopic plate 28 includes a rotating plate 281 with the same shape and size as the connecting plate 27. An inner groove 282 is formed on the rotating plate 281. A hollow pull-out plate 283 slides inside the inner groove 282, and an inner connecting plate 284 slides inside the hollow pull-out plate 283. The number of hollow pull-out plates 283 can be set arbitrarily, but the total length of the hollow pull-out plates 283 and inner connecting plates 284 when fully extended cannot exceed the length of the flexible hose 23. If two or more hollow pull-out plates 283 are provided, it can allow these... Hollow pull-out plates 283 are slidably connected, just like the inner connecting plate 284 that slides inside the hollow pull-out plates 283. The bracket plate 29 and the inner connecting plate 284 are fixedly connected. Both the rotating plate 281 and the hollow pull-out plates 283 are threaded with small lead rods. Small holes are opened on the outer surfaces of both the hollow pull-out plates 283 and the inner connecting plate 284. The small lead rods are located at the edges of the rotating plate 281 and the hollow pull-out plates 283. The small holes on the hollow pull-out plates 283 and the inner connecting plate 284 are all located at the positions corresponding to the small lead rods when both are pulled out.

[0029] The outer surface of the second mounting ring 25 has three equally spaced screw holes 210, which are distributed on the 180-degree arc surface of the outer surface of the second mounting ring 25. A connecting piece 211 that fits against the outer surface of the second mounting ring 25 is fixed on one side of the rotating plate 281. A screw 212 with a diameter that matches the inner diameter of the screw hole 210 is threaded onto the connecting piece 211. Three double elastic balls 213 are fixed on the outer surface of the second mounting ring 25. The three double elastic balls 213 are respectively set at the corresponding positions of the three screw holes 210. Each double elastic ball 213 includes two individual elastic balls, which are symmetrically distributed on both sides of the screw hole 210. The outer surface of the connecting piece 211 has two positioning holes 214, which include two individual positioning holes with sizes that match the individual elastic balls.

[0030] When in use: Before maintenance, the filter body 1 can be pulled out according to the direction where there are no objects blocking the filter body 1, such as in front of or above the filter body 1. Avoid objects around the filter body 1 from hindering the maintenance operation. First, screw the screw 212 out of the corresponding screw hole 210, and deflect the bracket plate 29 to the direction in which the filter body 1 needs to be pulled out. The bracket plate 29 will drive the telescopic plate 28 and the connecting plate 27 to rotate together. At the same time, the connecting piece 211 will rotate. When the connecting piece 211 rotates, the resistance and stopping feeling after the double positioning hole 214 and the double elastic ball 213 are engaged can be used to judge whether the screw 212 is aligned with the screw hole 210. After alignment, screw the screw 212 into the corresponding screw hole 210 to fix the direction of the telescopic plate 28.

[0031] Then, the filter body 1 can be pulled along the sliding connection direction of the telescopic plate 28 and the inner connecting plate 284. The filter body 1 will pull the inner connecting plate 284 so that it slides out of the hollow pull-out plate 283. Then, the position of the inner connecting plate 284 is fixed by screwing the small screw into the small hole. The hollow pull-out plate 283 is then pulled out of the inner groove 282. Then, the position of the hollow pull-out plate 283 is fixed by screwing the small screw on the rotating plate 281 into the corresponding small hole. In this way, the filter body 1 can be pulled out of its original installation position for maintenance work, avoiding the narrow space from hindering the maintenance work of the staff and making it convenient to maintain the filter.
