At the bottom inside the housing 1, there is an air chamber 13 for supporting the filter absorber. At the top inside the housing 1, there is a pressing ring 4. On the inner side wall of the housing 1, there is an air outlet docking flange 12 and two filter absorber mounting brackets 11 respectively located on the upper and lower sides of the air outlet docking flange 12;

[0024] The pressing ring 4 is movably arranged at the top inside the housing 1 and can move axially to achieve pressing on the top of the filter absorber;

[0025] On the filter absorber mounting bracket 11, there is a ratchet tie-down strap 5, and the ratchet tie-down strap 5 is used for binding and fixing the filter absorber body.

[0026] In a preferred solution, the cross-section of the air chamber 13 at the bottom inside the housing 1 is in an "L" shape. There is a through hole 8 on the outer wall of the housing 1, and the through hole 8 communicates with the vertical part of the air chamber 13. The filter absorber is installed on the horizontal part of the air chamber 13. External air flow enters the air chamber 13 through the through hole 8 and enters the filter absorber after passing through the horizontal part of the air chamber 13.

[0027] In a preferred solution, a top support 9 is welded and fixed on the top inner surface of the housing 1. A threaded adjustment ring 10 is fixed on the top support 9. The pressing ring 4 is a structure with a threaded hole, and the pressing ring 4 is installed on the threaded adjustment ring 10 by threads. A handle for adjusting the position of the pressing ring 4 on the threaded adjustment ring 10 is arranged outside the pressing ring 4.

[0028] In a preferred solution, a cushion block 2 is arranged at the bottom of the pressing ring 4, and a buffer pad 3 is fixed on the bottom surface of the cushion block 2. When the pressing ring 4 presses and fixes the filter absorber, the buffer pad 3 contacts the top surface of the filter absorber.
