Description

Technical Field

[0001] The utility model relates to the technical field of harmful gas detection, in particular to a harmful gas detection device. Background Art

[0002] Harmful gases are gases that have adverse effects on human or animal health, or gases that, while not harmful to human or animal health, can cause discomfort and affect their well-being. Examples include NH3, H2S, and CO. High concentrations of harmful gases are common in certain work environments, such as tunnels, underground pipelines, mines, confined spaces, and even spaces undergoing renovations. To ensure the health of workers, timely detection of harmful gases in the work environment is essential.

[0003] Announcement No. (CN219715249U) discloses a chemical harmful gas detection device. The air suction pump is turned on, and the external gas is sucked into the interior of the conical tube through the Y-shaped air suction pipe and the U-shaped air pipe. Then, the water pump is turned on at this time, and the water inside the water tank is sprayed out of the nozzle through the water supply hard pipe and the water supply hose. The water sprayed from the nozzle dissolves with the gas, and the liquid flows into the colorimetric tube through the inner wall of the conical tube. Part of the liquid will flow into the U-shaped air pipe. The liquid flows to the bottom of the U-shaped air pipe and flows back into the interior of the conical tube through the reflux pipe. The staff can observe the color of the liquid in the colorimetric tube inside through the observation window on the surface of the closed door. The above device can only detect harmful gases at a specific height, and the detection range is small, which needs to be improved. Utility Model Content
