Description

Technical Field

[0001] The utility model belongs to the technical field of carbon monoxide detection, and in particular relates to a portable carbon monoxide detector. Background Art

[0002] Pure carbon monoxide is a colorless, odorless, non-irritating gas. Carbon monoxide easily combines with hemoglobin to form carboxyhemoglobin, which causes hemoglobin to lose its oxygen-carrying capacity and function, causing tissue asphyxiation and death in severe cases. Carbon monoxide is toxic to tissue cells throughout the body, especially the cerebral cortex.

[0003] Criminal investigation staff will encounter various special environments during their work. In some special environments, the concentration of carbon monoxide will become higher and higher over time, posing a huge threat to the lives of staff. Traditional detection equipment is limited to fixed-site installation, which is not flexible and inconvenient to bring into the investigation scene. In addition, the density of carbon monoxide is less than that of air. In an indoor environment with poor air circulation, carbon monoxide will accumulate in the upper part of the room in advance. Existing handheld detectors cannot detect the air at high places in the room in time. Therefore, we proposed a portable carbon monoxide detector to solve the above problems. Utility Model Content
