An air inlet connector extending to the left end of the air inlet hole 11 is connected to the inner side wall of the air inlet hole 11. The air inlet connector is connected to the air outlet connector that has been installed on the left side, so that the gas at the air outlet connector can enter the air inlet connector. A partition plate 12 is provided in the left part of the main cabinet 10. The top surface, bottom surface, front side wall and rear side wall of the partition plate 12 are fixed to the corresponding inner side wall of the main cabinet 10. The partition plate 12 divides the main cabinet 10 into a filter chamber on the left and an adsorption main chamber on the right.

[0019] A centrifugal fan 20 is fixed on the inner wall of the adsorption main chamber. A central air inlet 121 is formed in the middle of the partition plate 12. The air outlet end of the centrifugal fan 20 is fixed on the inner wall of the right side plate of the main cabinet 10 and communicates with the air outlet 13 formed on the right side plate of the main cabinet 10. An air outlet connector 14 is fixed on the inner wall of the air outlet 13. The right end of the air outlet connector 14 extends out of the right end of the air outlet 13 and communicates with the air outlet 13. The air outlet connector 14 is connected to the exhaust connection pipe that has been installed on the right side of the main cabinet 10.

[0020] A filter housing 30 is inserted into the filter chamber, and the filter housing 30 cooperates with the filter chamber. The top surface of the filter housing 30 presses against the top surface of the filter chamber. The front and rear side walls of the filter housing 30 are in close contact with the front and rear side walls of the filter chamber. The upper and lower parts of the left side plate of the filter housing 30 are formed with through holes, which are aligned and connected with the corresponding air inlet holes 11. The middle part of the right side plate of the filter housing 30 is formed with a central through hole 31, which is connected and aligned with the central air inlet hole 121 of the partition plate 12. Filter mesh 32 is fixed on the inner side wall of the left side plate and the inner side wall of the right side plate of the filter housing 30, and the filter mesh 32 covers the corresponding through holes or the central through hole 31.

[0021] The bottom surface of the filter chamber extends out of the bottom plate of the main cabinet 10. A cover plate 40 is installed on the bottom surface of the bottom plate of the main cabinet 10. The top surface of the cover plate 40 presses against the bottom surface of the main cabinet 10 and covers the bottom surface of the filter chamber.

[0022] Furthermore, the filter housing 30 is filled with activated carbon particles.

[0023] Furthermore, the bottom surface of the bottom plate of the filter housing 30 is fixed with a gripping part 34, the bottom surface of the gripping part 34 presses against the top surface of the cover plate 40, the right end of the cover plate 40 is movably connected to the front and rear fixed connecting plates of the bottom of the main cabinet 10 through a hinge shaft, the front and rear of the middle part of the left side of the cover plate 40 are both formed with vertical screw holes, the left side of the left side plate of the main cabinet 10 directly above the left side of the cover plate 40 is fixed with an upper connecting block 15, the bottom surface of the upper connecting block 15 presses against the top surface of the left side of the cover plate 40, the screw part of the fixing bolt 16 is inserted into the corresponding vertical through hole formed on the upper connecting block 15 and screwed into the corresponding vertical screw hole, the upper part of the screw part of the fixing bolt 16 is fitted with a washer, the washer is clamped between the bottom surface of the rotating part of the fixing bolt 16 and the top surface of the upper connecting block 15.

[0024] Furthermore, a rectangular frame groove is formed on the bottom surface of the base plate of the main cabinet 10 around the bottom end of the filter chamber. The rectangular frame sealing strip 2 is nested in the rectangular frame groove, and the top surface of the cover plate 40 presses against the bottom surface of the rectangular frame sealing strip 2.

[0025] Furthermore, the outer side walls of the top and bottom of the filter housing 30 are formed with rectangular frame-shaped sealing grooves that surround the filter housing 30. The second sealing ring is nested in the corresponding sealing groove, and the outer side wall of the second sealing ring is in close contact with the inner side wall of the filter chamber.

[0026] In this embodiment, because it has two air inlet connectors, it can connect to two air outlet connectors. The centrifugal fan 20 operates, causing gas to enter through the air inlet connectors. After passing through the filter screen 32 on the left side of the filter housing 30 in the filter chamber, the gas enters the filter housing 30 and is adsorbed by the activated carbon particles inside, thus filtering out particulate matter such as dust. Then, it passes through the filter screen 32 on the right side (the pore size of the right filter screen 32 is smaller than that of the left filter screen 32, meaning the mesh size of the right filter screen 32 is larger than that of the left filter screen 32) and enters the main adsorption chamber. Finally, the centrifugal fan 20 discharges the gas from the air outlet connector 14 into the subsequent exhaust connector.

[0027] In this embodiment, after a certain period of use, the activated carbon granules need to be replaced and the filter screen 32 needs to be cleaned. At this time, simply rotate the fixing bolt 16 so that it is not connected to the cover plate 40. Then, the cover plate 40 will flip down. Then, hold the grip part 34 and pull the filter housing box 30 down to remove it from the filter chamber. The activated carbon granules can then be cleaned, rinsed and replaced. Simply open the bottom plate of the filter housing box 30 (which is fixed to the filter housing box 30 by bolts) to pour out and replace the activated carbon granules. At the same time, the filter screen 32 can also be disassembled for rinsing or replacement. Since the filter housing box 30 is removed from the main cabinet 10, it can be operated in a large space, making operation and replacement convenient and greatly improving the efficiency of replacement.

[0028] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
