Alcohol detector with both rough and precise detection functions

Abstract

The invention discloses an alcohol detector with both rough and precise detection functions, relating to the field of alcohol detectors. The alcohol detector comprises a shell, wherein one end of theshell is provided with a concave arc support, the support is internally provided with a plurality of infrared emitters and a plurality of infrared reflective-type sensors, the surface of the shell isprovided with a display screen, the shell is internally provided with a controller, the infrared reflective-type sensors, the infrared emitters and the display screen are all electrically connected with the controller, one end, far from the support, of the shell is provided with a sampling tube, the shell is further internally provided with an alcohol sensor, one end of the sampling tube is communicated with the alcohol sensor, and the alcohol sensor is electrically connected with the controller. In the alcohol detector with both rough and precise detection functions, besides a breath detecting system, a set of rough detection system based on an infrared detection principle is arranged; rough detection is completed by detecting on an arm, and a detected target suspected of drunk driving isprecisely detected in breath only according to a rough detection result, so that time is saved, and detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of alcohol detectors, in particular to an alcohol detector which integrates rough checking and fine checking. Background technique [0002] Alcohol detector is a common equipment used by traffic police to investigate and deal with drunk driving. In the prior art, a single breath alcohol detector is generally used for detection. During the detection, the person to be tested is asked to blow air to the alcohol detector, and the alcohol concentration in the blood of the person to be tested is calculated by detecting the alcohol concentration in the blown gas. , so as to determine whether it is drunk driving or drunk driving. However, in the actual law enforcement process, due to the use of breath alcohol detectors for detection, some tested persons will resist behaviors due to hidden health concerns, which makes law enforcement difficult. In order to eliminate the above-mentioned hygienic concerns, in the prior art, di...

AI Technical Summary

Problems solved by technology

However, in the actual law enforcement process, due to the use of breath alcohol detectors for testing, some of the tested personnel will have resistance behaviors due to hidden health concerns, which makes law enforcement difficult.

In order to eliminate the above hygienic concerns, in the prior art, disposable blowpipes are often used in detection, but the installation and disassembly of disposable blowpipes are not convenient enough, and the traffic police have a large workload and waste a lot of time during drunk driving inspections.

Some people suspected of drinking and driving, in order to avoid punishment, use various methods when blowing, including fake blowing, inhaling, etc., and the alcohol test requires a certain amount of testing time. It will waste a lot of time and affect the inspection efficiency
