DETECTION ACCURACY ENHANCING STRUCTURE OF PARTICLE DETECTING MODULE

Abstract: a detection accuracy enhancing structure of a particle detecting module is provided. a detection accuracy enhancing structure comprises an anti-scatter structure and two stray light suppression treatment structures. the anti-scatter structure is disposed in the gas-inlet groove of the base corresponding to a projection area of the laser component. the two stray light suppression treatment structures are respectively arranged in the light trapping region and the gas-inlet groove corresponding to the projection area of the laser component. when the light beam emitted from the laser component is reflected to the light trap region and the gas-inlet groove, the anti-scatter structure and the two stray light suppression treatment structures reduce a stray light directly reflected to the particulate sensor, so as to enhance the detection accuracy.
