[0002] With the vigorous development of the industrial manufacturing industry, various types of deflagration and explosion accidents have occurred frequently in petroleum, chemical, and dust explosion-related manufacturing companies due to poor management and ineffective safety precautions. With the popularization of explosion suppression and fire extinguishing technology, similar large-scale explosion disasters have been effectively avoided. The explosion suppression and fire extinguishing system can quickly and effectively extinguish the fire as soon as it occurs through the cooperation of the detection unit, control unit and execution unit, thereby suppressing and eliminating the occurrence of dangers and safety accidents such as combustion and explosion from the source.

[0003] In the explosion suppression and fire extinguishing system, smoke detectors, as the detection unit of the system, can detect fire promptly and effectively when it just occurs, and prevent fire by monitoring the concentration of smoke. Most common smoke detectors use infrared beam smoke detectors to detect fire in real time through the characteristic that light will be deflected under different smoke concentrations.

Since most smoke detectors are installed outside the device, they often do not have a certain protective structure, which causes the smoke detectors to be damaged, thereby affecting the detection accuracy of the explosion suppression and fire extinguishing system; 2. Most smoke detectors adopt an integrated structure. When the internal components are damaged, it is not easy to open the smoke detector to replace the internal components, resulting in reduced maintenance efficiency of the smoke detector, which in turn affects the detection effect of the explosion suppression and fire extinguishing system.
