The invention discloses an alcohol test device which comprises an alcohol test unit and a control assembly, wherein the alcohol test unit comprises one alcohol test sensor, an air inlet and an air outlet; the air outlet is respectively connected with a circulating type air exhaust component and a reciprocating type air exhaust component by a connecting pipe; a valve is arranged at the part of the connection pipe between the air outlet and the circulating type air exhaust component; when the circulating type air exhaust component works, the tested air flows into the circulating type air exhaust component through the valve; otherwise, the tested air can not flow into the circulating type air exhaust component through the valve; the circulating type air exhaust component and the reciprocating type air exhaust component are respectively connected with the control assembly in a control way. The alcohol test device only adopts one alcohol test sensor, so that a great deal of cost is saved, the volume of the device is reduced, and the failure rate is reduced; when the circulating type air exhaust component is used, the water vapor and the alcohol which are left on the sensor can be cleaned by the circulating type air exhaust component, so that the detection accuracy during a reciprocating type test can be further improved; the alcohol test device is high in practicality, and has market value and social benefit.
Description
technical field [0001] The invention relates to the technical field of alcohol testing, in particular to an alcohol testing device. Background technique [0002] From factories and enterprises to residents' families, the detection and monitoring of alcohol leakage and the monitoring of drunk driving are very important and indispensable to the personal and property safety of residents. With the rapid development of China's economy and the continuous improvement of people's living standards, all kinds of motor vehicles have become an indispensable part of people's lives, especially the emergence of private cars, which undoubtedly greatly improves the efficiency of people's life and work. The problem also follows, this is the problem of safety. Traffic accidents caused by drunk driving are due to the driver's excessive drinking, which causes the alcohol concentration in the human body to be too high, which paralyzes the nerves, causes the brain to respond slowly, and the limbs...
