Description

Technical Field

[0001] This utility model belongs to the technical field of hazardous chemical detectors, and specifically relates to a hazardous chemical detection device. Background Technology

[0002] Hazardous gas detectors are devices used to detect leaks or the presence of hazardous chemicals. They are widely used in industries such as chemical, petroleum, and natural gas, as well as in emergency rescue and environmental monitoring. Common sensor types for hazardous gas detectors include electrochemical sensors, semiconductor sensors, infrared sensors, ion mobility spectrometry (IMS) sensors, and Raman spectroscopy sensors. Among them, electrochemical sensors are suitable for detecting toxic gases such as carbon monoxide and hydrogen sulfide; infrared sensors are commonly used to detect flammable gases.

[0003] Patent application number 202321904001.X discloses a hazardous chemical safety testing device, including a housing, a handle, and an air inlet. A display is fixed to the top center of the housing, and a control button is located on the right side of the display. A buzzer is located to the right of the control button. The handle is connected to the right side of the housing, and a power supply is located inside the handle. An air inlet is located on the left side of the housing, and a sampling pump is located inside the housing to the right of the air inlet. The sampling pump is connected to a light source heat exchange chamber through a sampling pipeline. A light source is located inside the light source heat exchange chamber, and a light chamber is connected to the bottom of the light source heat exchange chamber. A spectrometer is connected to the bottom of the light chamber.

[0004] The above-mentioned technical solution uses the air inlet to detect air containing hazardous chemicals, mainly relying on the natural diffusion of gas to contact the sensor. However, in relatively still environments such as indoors, the air is difficult to circulate and diffuse, affecting the detection effect. At the same time, when detecting pipes in narrow spaces, it is necessary to handheld the detector and extend it into the interior of the narrow space, which is not convenient for detection.
