The air outlet slot in front of the test fan 6 is for exhausting air, and the air inlet slot behind the test fan 6 is for intake of air. During the movement of the test fan 6, the number of air inlet slots and air outlet slots changes. The closer the test fan 6 is to the inspection doors and windows, the fewer air outlet slots and the more air inlet slots there are. Therefore, the air intake volume is much greater than the air outlet volume. In addition, since the test fan 6 is closer to the inspection doors and windows, the greater the wind force on the inspection doors and windows, and vice versa, the smaller the wind force on the inspection doors and windows.
