Description

Technical Field

[0001] The utility model belongs to the technical field of dust monitoring equipment, in particular to an online dust monitor. Background Art

[0002] A dust monitor is a dust monitoring instrument that uses microcomputer laser control to monitor dust and other particulate matter in the air. With the development of environmental protection and the improvement of people's environmental awareness, people have higher standards for air quality, so the application of dust monitors is becoming more and more extensive. It is suitable for monitoring the emission of particles, tornadoes, dust collectors or any dust prevention equipment. In real life, when a dust monitor monitors environmental dust, the monitoring probe on the instrument will be placed outside. Since most dust monitors do not have a cleaning mechanism, it is impossible to clean the dust attached to the surface of the monitoring probe. After a long period of monitoring, it will affect the accuracy of the data collected by the monitor, thereby reducing the monitoring effect.

[0003] A Chinese patent document (application publication number CN219245306U) discloses an online dust monitoring device, which includes a monitor, a monitoring probe and an antenna are provided on the top of the monitor, two positioning structures are provided on the top of the monitor, a same protective cover is movably provided on the two positioning structures, trapezoidal blocks are fixedly provided on both sides of the protective cover, a hoop is provided on the back of the monitor, and a mounting plate is fixedly provided on one side of the monitor.

[0004] It can be seen that the patent document cited above also has the same problem. Although it can complete the rapid disassembly and assembly of the protective cover and protect the display screen when the equipment is idle and not in use, preventing the equipment screen from being damaged by external impact, the monitor lacks a monitoring probe cleaning mechanism. When dust adheres to the surface of the monitoring probe during monitoring, it cannot be cleaned. After long-term monitoring, it will affect the accuracy of the data collected by the monitor, thereby reducing the monitoring effect. Utility Model Content
