The detectors 92 are fixedly connected to the top two sides of the sealing frame 93.

[0040] When in use, the air duct 82 circulates gas to blow the activated carbon inside the activated carbon placement tube 81, causing the activated carbon to fall off for odor treatment, and the circuit board is taken out after drying. At this time, the telescopic body 74 drives the elastic cleaning member 72 to move horizontally to wipe the placement rack 52, and the positioner 75 detects the moving position of the elastic cleaning member 72 in real time. At the same time, the horizontal pushing member 94 pushes the scraper plate 91 inside the sealing frame 93 to concentrate the impurities inside the collection box 571. Embodiment 3
