After the mask has been in the detection box 1 for a certain period of time, observe whether there is dust on the surface of the filter 10 or the residual dust on the surface of the filter 10, so as to detect the mask.

When the first fan blade 16 rotates, the second rotating shaft 35 is driven to rotate, and the second rotating shaft 35 is driven to rotate at the same time by the large gear 36, so that the first rotating shaft 32 rotates in the middle of the rotating seat 31, and the first rotating shaft 32 is driven to rotate by the small gear 33 to make the second fan blade 34 rotate to blow air toward the mask position, so that the dust inside the detection box 1 flows toward the mask position, and the second fan blade 34 is driven to rotate by the fixed plate 3 and the mesh plate 37. For blocking protection, when the mask is undergoing dust detection, the heating lamp 41 is powered on and turned on to control the heating lamp 41 to heat the inside of the detection box 1. The heating lamp 41 is used to simulate mask detection at different temperatures. When the mask detection is completed, the dial plate 53 is moved to move the scraper 52, and the scraper 52 slides inside the slide rail 5 through the slider 51.
