It should be noted that, the detecting component 200, the dust filtering component 300 and the suction fan 400 are all installed in the chassis 100, and the detecting component 200, the dust filtering component 300 and the suction fan 400 are sequentially communicated, wherein the detecting component 200 is communicated with the air inlet 121, and the suction fan 400 is communicated with the suction fan 400. In this way, after the air at the blasting site is pumped into the detection assembly 200 through the air inlet hole 121 for detection, the air is filtered by the dust filtering assembly 300, and then is exchanged to the outside through the air outlet hole by the suction fan 400. The dust is filtered by the dust filtering component 300, so that the dust in the air is prevented from entering the suction fan 400 to damage the suction fan 400.
Specifically, the detection box 210 is installed in the chassis 100, for example, only a fixing leg is installed at the bottom of the detection box 210, and the fixing leg can be locked and fixed in the chassis 100 by a bolt.

Thus, when the air in the blasting site enters the detection box 210 from the air inlet hole 121, the laser emitter 240 emits laser to irradiate the air in the detection box 210, then dust in the air scatters the laser, and the scattered light is reflected under the action of the reflecting plate 230, so that the reflected light is received by the silicon photocell 220. The silicon photocell 220 is a photoelectric device, and the amount of dust in the air is different, so that the amount of light received by the silicon photocell 220 is finally changed, the current and the electromotive force of the silicon photocell 220 are changed, and the concentration of the dust in the air is calculated through a control system. Further, since the gas to be detected is introduced into the cartridge 210 and stays therein for a short time, dust is easily accumulated in the cartridge 210, and in order to facilitate cleaning and maintenance of the cartridge 210, the silicon photocell 220, the reflecting plate 230 and the laser emitter 240 are configured to be detachably mounted with respect to the cartridge 210.
