[0033] Working principle: When the nitrogen dioxide in the air exceeds the standard, it will be detected by the sensor 3. At this time, the warning light 22 and the horn 23 will cooperate to alarm. After the nitrogen dioxide alarm has been used for a long time in a dusty scene, the surface used for detection on the rear side of the filter hole 2 and the front side of the sensor 3 will be covered with dust. At this time, the electric push rod 4 will push the connecting column 5 to move the two cleaning plates 10 to clean the filter hole 2 and the sensor 3 respectively. The cleaned dust will fall into the dust storage 13. While cleaning, the pushing spring 7 will push the connecting seat 8 to push the pushing rod 9, and the pushing rod 9 will also cooperate with the connecting rod 11 to make the cleaning plate 10 close to the object to be cleaned. By keeping the cleaning plate 10 close to the object to be cleaned at all times while cleaning the sensor 3 and the filter hole 2, the object can be moved more effectively. In order to remove dirt, dust and other pollutants, the cleaning efficiency is improved. When the dust in the dust container 13 needs to be cleaned, the top of the two lower pressure plates 16 on the far side is pressed by the same hand at the same time. While squeezing the push spring 2 19, the lower pressure plate 16 will pull the card column 18 out of the card slot 14 through the connecting ring 17. At this time, the dust container 13 will fall out from the inside of the alarm 1 and needs to be caught by hand in advance. When the internal cleaning of the dust container 13 is completed, the dust container 13 is reinserted into the interior of the alarm 1. At this time, release the hand pressing the two lower pressure plates 16, and the card column 18 will be pushed by the push spring 2 19 and the lower pressure plate 16 to re-engage with the card slot 14 to fix the dust container 13. By quickly disassembling the dust container 13, maintenance becomes more convenient, the maintenance time is shortened, and the maintenance work efficiency is improved.
