The invention discloses an alcohol tester, comprising an air inlet, an alcohol gas sensor, a first air outlet, a second air outlet, a single chip computer, a display, an exhausting pump, a cleaning unit and a power module, wherein the exhausting pump is arranged at the first air outlet and is connected with the single chip computer; the cleaning unit comprises a cleaning component, a flexible connection rod and a mini motor and is arranged at the second air outlet; the mini motor is connected with the single chip computer, the second air outlet is connected with the alcohol gas sensor, and a second electronic valve is arranged at the connection part of the second air outlet and the alcohol gas sensor and is connected with the single chip computer; the air inlet is connected with the alcohol gas sensor, and the single chip computer is connected with the display. The alcohol tester can immediately control the exhausting pump to test gas residual in the alcohol tester and control the cleaning unit to clean residual stain; therefore, the accuracy of a next test is ensured, and the sanitation of the next test is also ensured.
Description
technical field [0001] The invention relates to the field of alcohol testing, in particular to an alcohol testing device. Background technique [0002] At present, the test for drunk driving is directly related to the personal and property safety of residents and social public order. 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 are out of control and other symptoms. At present, almost all countries use breath alcohol testers to carry out on-site detection of drivers to determine whether the measured driver has drunk alcohol. Now there are many types on the market. With the development of technology, the function is getting stronger and the sensitivity is getting higher and higher. It can effectively assist the traffic police to spot check whether the driver is drinking or not. However...
