TECHNICAL FIELD

[0001] The utility model relates to the technical field of gas monitoring, specifically to a greenhouse gas real -time monitoring device. BACKGROUND

[0002] Greenhouse gas refers to some gases in the atmosphere that can absorb long-wave radiation reflected by the ground and reemit radiation, such as water vapor, carbon dioxide, most refrigerants, etc. Their role is to make the earth's surface warmer, similar to the role of a greenhouse trapping solar radiation and heating the air inside the greenhouse.

[0003] A greenhouse gas monitoring device is provided in Chinese patent with publication number CN216411216U, which includes a device housing and a gas inlet pipe opened inside the device housing. The bottom end of the gas inlet pipe is provided with an air inlet. One side of the device housing is fixedly connected with an adjusting housing. The adjusting housing is internally provided with a mounting mechanism. The mounting mechanism includes a bidirectional screw rod.

[0004] The above device controls the bidirectional screw rod through a knob. By rotating the bidirectional screw rod, the distance between the two clamping blocks is changed, facilitating the installation of the monitoring device. The fixed suction cup makes the monitoring device more firmly installed. The two sides of the movable box are symmetrically fixedly connected with plug-in rods, which are L-shaped structures, facilitating the connection between the movable box and the pull-out cabinet, and facilitating the replacement of the filter cotton. The second filter screen is located below the filter cotton, which can screen the gas step by step, avoid dust and other impurities entering the gas inlet pipe, and be adsorbed on the monitoring device, affecting the use of the monitoring device.

[0005] However, the air entering through the filter screen and filter cotton is filtered and dusted. When the inhaled air is relatively humid, the probability of dust adhering to the filter cotton increases, resulting in a higher replacement frequency of the filter cotton. During the replacement process, in order to protect the detector, the detector is stopped, real-time detection is difficult, and the use effect is affected. Utility model content
