Technical Field
The utility model relates to a gaseous detection device, especially a carbon monoxide alarm device.
Background
Carbon monoxide (CO) gas is a colorless, odorless, non-irritating, toxic gas that cannot be sensed by the five sense organs, and can inhibit the oxygen carrying capacity of blood. The toxicity of carbon monoxide mainly affects the supply and utilization of oxygen, and the affinity of carbon monoxide with red blood cells is more than 300 times greater than that of oxygen with red blood cells, so that human tissues are lack of oxygen. After carbon monoxide gas is inhaled, carbon monoxide enters the lung and is combined with red blood cells in advance, so that the red blood cells lose the capability of transporting oxygen, and a plurality of organs of a human body are subjected to oxygen deficiency, so that tissues are damaged and even die. Generally, people can not be aware of the intoxication by accident, and often are in a coma state when being discovered, which leads to serious injury and even death. The carbon monoxide alarm device is characterized in that the carbon monoxide sensor senses the concentration of carbon monoxide gas in air and converts the carbon monoxide gas into an electric signal, and the magnitude of the electric signal is related to the concentration of carbon monoxide. The sensor of the traditional carbon monoxide alarm is directly exposed in the measuring environment and is easily polluted by moisture, smoke dust and the like, so that the measuring result and the precision are influenced.
