The air receiving foot pedal 33 controls the amount of air entering the telescopic cylinder 31 to control the extension and contraction of the telescopic cylinder 31. The extension and contraction of the telescopic cylinder 31 drives the pressing frame 32 to move, thereby pressing the filter on the detection clamping plate 2.

[0030] The smoke generating device 4 includes a particle generator 41, a PAO oil generator 42 and a fan 43, and the particle generator 41 and the PAO oil generator 42 are connected to the fan 43 through a pipeline. The fan 43 is arranged at the air outlet 21. The particle generator 41 is used to generate particles, and the PAO oil generator 42 is used to generate smoke.
