[0002] Smoke monitoring: through the monitoring of smoke density, the content of smoke in the air in a specific area can be intuitively understood, so as to judge whether the area is in a clean, light pollution, moderate pollution or heavy pollution state, so as to fully understand the advantages and disadvantages of ambient air quality. For example, according to the relevant air quality standards, when the smoke density is within a certain range, it can be determined that the air quality is good, and exceeding a certain threshold means that the air quality is poor, providing basic data support for subsequent further analysis and response measures.

[0003] The existing detection device has a simple structure, which is designed in an open structure, so that the air flows into the monitoring cavity during the flow process, and then is detected by the optical element of the sensor. The open structure design is prone to dust entering and accumulating, affecting the sensitivity and accuracy of the element. For example, if the optical lens in the laser scattering smoke monitor is covered with dust, the light propagation and scattering will change, resulting in deviation of the measurement result. In view of this, we propose a smoke and dust monitoring device in ambient air. SUMMARY

[0007] Preferably, the adjusting mechanism is composed of a push plate and an assembly box, an electric telescopic rod is arranged in the assembly box, and the outer end of the electric telescopic rod is fixed on the push plate.

[0008] Preferably, the front end opening of the box body is provided with a butt joint on both sides, and a fixed shaft is arranged in the butt joint.

[0009] Preferably, the inside opening door is designed as a double-opening type, a sleeve is fixed to the outside of the inside opening door, the sleeve is rotatably sleeved on the fixed shaft, a coil spring is arranged in the sleeve, and the coil spring is connected between the sleeve and the fixed shaft.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1. This utility model features an inward-opening door that seals the detection chamber opening at the front of the housing. When not in use, the device is in a relatively closed state, preventing external dust and rain from entering the detection chamber and thus avoiding any impact on the optical components of the laser scattering sensor. This ensures the accuracy of monitoring during use. The device is activated in stages. By activating the electric telescopic rod, the push plate is retracted to the opening of the assembly box. A coil spring then causes the inward-opening door to deflect inward into the detection chamber, allowing outside air to enter. The laser scattering sensor then detects the dust content. This staged opening and closing design extends the device's lifespan and prevents the accumulation of large amounts of dust from reducing detection accuracy.

[0015] 2. This utility model also features a box design with adjustment mechanisms on both sides. When the push plate of the adjustment mechanism is pushed outward, it causes the retracted inner door to open outward, simultaneously pushing the dust-laden airflow in the detection chamber outward during the opening process. After the box is completely closed, the dust content in the detection chamber is greatly reduced, ensuring the accuracy of continuous operation of the device. When the push plate is retracted, the inner door is driven to retract inward by a coil spring, and the inner door pushes the airflow in the detection chamber out from the side. At this time, the external airflow is guided to flow into the detection chamber, realizing the filling of the detection chamber by the external airflow, which facilitates dust detection and reduces the difficulty of operation.
