Multifunctional expiration type alcohol content detector

Abstract

The invention discloses a multifunctional expiration type alcohol content detector. The detector comprises an upper shell (1), a lower shell (2), a circuit board (3) and a power supply (4); an electrochemical sensor (5) is mounted on the inner side of the circuit board and between the upper shell and the lower shell; a traffic guidance light emitting stick (6) is sleeved on the outer side of the circuit board; and outer covers (8) are mounted at the outer ends of the upper shell and the lower shell through window breakers (7). In the lower shell, a trumpet (15) is mounted between the power supply and the electrochemical sensor; an end cover (16) is mounted at the outer end of the traffic guidance light emitting stick; and an illumination lamp is mounted on the end cover. The detector is capable of realizing the functions of alcohol detection, window breakage, traffic guidance, alarm whistle (voice prompt), patrol illumination, magnetic suction and the like through a same alcohol detection device during the traffic investigation, so as to bring convenience to the carrying and operation, remarkably improve the the working efficiency and leisurely confront the complicated situations of deforcement and the like.

Description

technical field [0001] The invention relates to an alcohol detector, in particular to a breath-type alcohol detector used by traffic police to detect drunk driving. Background technique [0002] At present, the alcohol detector (breath type) used by the traffic police is based on the fact that the breath alcohol tester contains an electrochemical sensor. When the alcohol molecules in the breath sample pass through the electrochemical sensor, the alcohol is converted into acetaldehyde. Since the release of electrons causes changes in the current of the electrochemical sensor, the microprocessor (circuit board) measures the current of the sensor, thereby quickly and accurately measuring the alcohol content in the breath, and converting it into the alcohol content in the blood. In duty tasks, in addition to the single facility and single function of the alcohol detector, in order to deal with complex situations such as car drivers who may resist law enforcement, it is necessary...

Problems solved by technology

In duty tasks, in addition to the single facility and single function of the alcohol detector, in order to deal with complex situations such as car drivers who may resist law enforcement, it is necessary to carry multiple facilities such as traffic batons and warning lighting horns at the same time. , operation brings inconvenience, and also affects work efficiency
