Then the uniform sampling detection component 7 and the automatic adsorption placement component 8 are lifted, and the small dry ice particle maker 401 is started to generate dry ice particles. The generated dry ice particles are transported to the pumping pump chamber 402 through the dry ice particle guide pipe 408. Then the pumping pump chamber 402 transports the dry ice particles to the dry ice particle injection end 407 through the top output end, and the rotating joint structure 403 adjusts the angle of the adjustment arm structure 404 so that the dry ice particle injection end 407 is aligned with the area to be cleaned by the uniform sampling detection component 7 and the automatic adsorption placement component 8. Combined with ultrasonic vibration, the dry ice particles can more effectively remove surface dirt and residues. After that, the pre-prepared dish sample after sampling detection is taken out from the placement fixing seat 12 through the external material collection structure to complete the entire detection process.
