The first end of the wire groove 12 is connected to the central cavity 11, and the second end forms a first connecting port 13 on the side of the base 1.

[0035] The sensor body 3 is arranged corresponding to each wire groove 12. The sensor body 3 is fixedly mounted on the bracket 31. A first vertical groove 71 matching with the bracket 31 is processed on the base 1. The top of the first vertical groove 71 forms a socket, and the bottom is closed to form a limit end. The bracket 31 is inserted into the first vertical groove 71 so that it can be plugged and matched with the base 1 up and down, and has a sensor assembly position for the sensor body 3 to enter the wire groove 12. In this sensor assembly position, the detection end of the sensor is arranged in the direction of the first connecting port 13. And in this sensor assembly position, the bracket 31 is limited by the first vertical groove 71 to move downward relative to the base 1.

[0036] The side of the base 1 is processed with a first cavity 14 and a second cavity 15. The bottom surface of the first cavity 14 is processed with a second connecting port 16 connected with the central cavity 11. The aforementioned exhaust device is arranged in the first cavity 14 so as to be able to discharge the air in the first cavity 14 to the outside of the base 1. The aforementioned exhaust device includes a first assembly plate 51 and an exhaust fan 5 fixedly mounted on the first assembly plate 51.

When the sealing plate 2 is disassembled, the wire slot 12 and the central cavity 11 can be opened to facilitate the cleaning of dust and the like in the wire slot 12 and the central cavity 11. At the same time, the sensor body 3, the exhaust device and the display screen 4 components are all installed on the base 1 by plugging, without the need for fixing with screws, thereby simplifying the disassembly and assembly steps of each component. The modular design facilitates the disassembly and assembly of each connector, the disassembly and assembly of the sensor body 3, the disassembly and assembly of the exhaust device and the disassembly and assembly of the display screen 4 components, effectively improving the convenience of disassembly and assembly and having strong practicality.

[0043] When in use, the sealing plate 2 covers the central cavity 11 and the wire groove 12 at the sealing position, so that a gas flow channel is formed between the wire groove 12, the central cavity 11, and the first concave cavity 14. When the exhaust fan 5 is in operation, the outside air enters the wire groove 12 and the central cavity 11 in sequence through the first connecting port 13, then enters the first concave cavity 14 through the second connecting port 16, and then is discharged from the air outlet. The sensor body 3 is arranged in the wire groove 12 to monitor the harmful gas flowing in the air flow channel. When no environmental monitoring is performed, the first connecting port 13 can be closed to prevent dust, water vapor, etc. from entering the wire groove 12, and effectively protect the sensor body 3.
