Then the lead screw 13 drives the driving thread block 15. By moving up or down, the driving thread block 15 can drive the cylinder 10 to perform upper air intake work or lower air outlet work. Because the air inlet device 7 and the air outlet device 8 are driven simultaneously, air intake and air outlet work can be carried out. In this way, the purpose of dry-wet separation can be achieved, and the situation of excessive water vapor in the test chamber can be prevented.

[0023] Furthermore, an operation screen 16, a control panel 17, and a flow meter 18 are respectively provided on the detection box body 2.
