A rubber ring 27 is fixedly fitted on the outer peripheral wall of the placement plate 15.

[0030] Among them, the two mounting slots 21 are located at the top and bottom of the placement slot 20 respectively, and both mounting slots 21 are connected to the placement slot 20. The rubber ring 27 fits into the placement slot 20. The moving plate 24 is slidably connected to the mounting slot 21. The positioning rod 25 and the positioning hole 25 are fitted with a clearance. The telescopic rod 23 consists of a sleeve and a moving rod. One end of the moving rod passes through and extends into the inside of the sleeve.

[0031] It should be noted that the air compressor pump 18 is a conventional device known to the public in the prior art, and its specific structure and working principle will not be described in detail in this article.

[0032] Specifically, pulling the movable plate 24 causes the positioning rod 25 to move, allowing it to enter the mounting groove 21. The sliding connection between the movable plate 24 and the mounting groove 21 supports the movable plate 24, improving its stability. Pushing the placement plate 15 allows it to enter the placement groove 20. The positioning rod 25 and the positioning hole 26 are on the same center line. The rubber ring 27 fits into the placement groove 20, supporting the placement plate 15 and improving its stability. Releasing the movable plate 24 causes the telescopic rod 23 to reset under the action of the spring 22. The movable plate 24 and the placement plate 15 fit together, and the positioning rod 25 is inserted into the positioning hole 26. Through the clearance fit between the positioning rod 25 and the positioning hole 26, the air intake pipe 16 is fixed to the first chamber 1. The air compressor pump 18 is started, and exhaust gas enters the air compressor pump 18 through the air intake pipe 16. The compressed exhaust gas is then discharged through the exhaust pipe 17.

[0033] In this embodiment, a filter assembly is provided between the first chamber 1 and the second chamber 4. The filter assembly includes a filter plate 7, which is placed inside the first chamber 1 and extends into the second chamber 4. A filter screen 12 is fixedly embedded on the left side of the filter plate 7. Positioning grooves 14 are provided on opposite sides of the first chamber 1 and the second chamber 4. A positioning block 13 with one end extending into the two positioning grooves 14 is fixedly connected to the bottom surface of the filter plate 7. A connecting groove 6 is provided on the left side of the second chamber 4, and a limiting chamber 5 is fixedly connected to the left side of the second chamber 4.

[0034] The positioning block 13 and the positioning groove 14 are fitted together. The first compartment 1 and the second compartment 4 are both cuboids that are hollow inside and missing one side. The limiting compartment 5 is an isosceles trapezoidal truncated cone that is hollow inside and missing both the left and right sides. The connecting groove 6 is covered by the limiting compartment 5.

[0035] Specifically, the filter plate 7 is placed inside the first chamber 1, and the positioning block 13 is inserted into the positioning groove 14 to restrict the filter plate 7. The second chamber 4 is fitted into the first chamber 1 to fix the filter plate 7. The exhaust gas passes through the filter screen 12, which filters impurities on the exhaust gas, and then enters the first chamber 1.

[0036] In this embodiment, a drive assembly is provided between the first compartment 1 and the second compartment 4. The drive assembly includes two fixing plates 19, which are fixedly connected to the top surfaces of the first compartment 1 and the second compartment 4, respectively. Mounting plates 11 are fixedly connected to the bottom surfaces of both the first compartment 1 and the second compartment 4.

[0037] The limiting rod 9 and the limiting hole 10 are fitted with a clearance, and the left side of the driving rod 2 is provided with a threaded hole. The screw 3 extends into the inside of the threaded hole and is threadedly connected to it.

[0038] Specifically, rotating the drive rod 2 causes it to rotate. Through the threaded connection between the drive rod 2 and the screw 3, and the clearance fit between the limiting rod 9 and the limiting hole 10, the screw 3 drives the second chamber 4 to move to the right through the fixing plate 19. The second chamber 4 and the first chamber 1 are in contact, which in turn causes the baffle 8 and the left mounting plate 11 to be in contact, thus fixing the filter plate 7.

[0039] The working principle of the above embodiments is as follows:

[0040] Pulling the movable plate 24 causes the positioning rod 25 to move, allowing it to enter the mounting groove 21. The sliding connection between the movable plate 24 and the mounting groove 21 supports the movable plate 24, improving its stability. Pushing the placement plate 15 allows it to enter the placement groove 20. The positioning rod 25 and the positioning hole 26 are aligned on the same center line. The rubber ring 27 fits into the placement groove 20, supporting the placement plate 15 and improving its stability. Releasing the movable plate 24 causes the telescopic rod 23 to reset under the action of the spring 22. The movable plate 24 and the placement plate 15 fit together, and the positioning rod 25 is inserted into the positioning hole 26. Through the clearance fit between the positioning rod 25 and the positioning hole 26, the air intake pipe 16 is fixed to the first chamber 1. The filter plate 7 is then placed into the first chamber. Inside chamber 1, positioning block 13 is inserted into positioning groove 14 to restrict filter plate 7. Rotating drive rod 2 causes it to rotate. Through the threaded connection between drive rod 2 and screw 3 and the clearance fit between limit rod 9 and limit hole 10, screw 3 drives second chamber 4 to move to the right through fixing plate 19. Second chamber 4 and first chamber 1 are in contact, thereby causing baffle 8 and left mounting plate 11 to be in contact, fixing filter plate 7. Air compressor pump 18 is started, and exhaust gas enters the interior of second chamber 4 through connecting groove 6. Exhaust gas passes through filter screen 12, which filters impurities on exhaust gas. Exhaust gas enters the interior of first chamber 1 through filter screen 12. Under the delivery of air inlet pipe 16, exhaust gas enters the interior of air compressor pump 18, and then is discharged through air outlet pipe 17.
