The fixing ring 22 can be fixed to the surface of the test chamber 1 by the fixing bracket 2. The interior of the rotating cover 9 is connected to the vent 4. The direction of communication with the outside is changed by the connecting tube 12. When one side of the vent 4 is against the wall, air can be injected into the test chamber 1 through the connecting tube 12. Inside the test chamber 1, the rotating cover 9 can be adjusted to multiple angles. By connecting the connecting pipe 12 to the protrusion 19, air can enter the interior of the test chamber 1 from other positions. The filter element 21 is fixed in the docking groove 20. When the filter element 21 needs to be cleaned or replaced, simply pull the rotating cover 9 out of the annular groove 3 and rotate it. The surface of the extension pipe 18 is provided with the protrusion 19, and the surface of the fixing ring 22 is provided with the groove 23.
