Fully automatic piston type fingerprint sweat collecting chamber

Abstract

The invention discloses a fully automatic piston type fingerprint sweat collecting chamber, comprising a fingerprint recognizer. The invention is characterized in that the recognizer is arranged in a piston type detector, the piston type detector is further provided with a screw type piston, the front part of the detector is a detecting chamber, the back part thereof is a motor room; the motor room is provided with an electric motor, an output shaft of the electric motor is fixed with a gear, the gear surface of the gear is articulated with a screw of the screw type piston, a piston head of the screw type piston enters the detecting chamber and is inosculated with the front end of the detecting chamber, the fingerprint recognizer is fixed on the lower part of the detecting chamber, the lateral wall of the detecting chamber is provided with gas path through holes which are connected to the air inlet of an alcohol detector, the air outlet thereof is communicated with an pump. The invention has the obvious effects that before driving, each driver is subjected to compulsory alcohol testing, so as to take preventive measures in advance while ensuring the driver is qualified in terms of identity.

Description

technical field [0001] The invention belongs to an alcohol content detection and identity verification system, in particular to a full-automatic piston type fingerprint sweat collection chamber for detecting the alcohol content in human volatilized sweat. Background technique [0002] Drunk driving is likely to cause traffic accidents, so it has always been one of the items strictly investigated by the traffic control department. The current method for detecting whether a driver is driving under the influence of alcohol is to determine whether the driver belongs to driving under the influence of alcohol by detecting the amount of alcohol contained in the driver's exhaled gas after the traffic police stopped the suspicious vehicle. This detection method is random and passive, and most drivers who drink and drive are not detected, and can only deal with the driver after the event, and cannot prevent beforehand, and the driver is prohibited from drinking and driving. At the sa...

AI Technical Summary

Problems solved by technology

This detection method is random and passive, and the vast majority of drunk driving drivers have not been detected, and the driver can only be dealt with after the event, and cannot be prevented in advance. Drivers are prohibited from drinking and driving

At the same time, this detection method requires the driver to blow air on the detection instrument with his mouth, which is likely to cause cross-infection and is unhygienic.

For a vehicle that uses a fingerprint reader to verify the driver's identity, it can only prevent the vehicle from being stolen, but it cannot confirm whether the driver is driving under the influence of alcohol, and there is no guarantee for the driving safety of the vehicle.

[0003] The defective of prior art is: can only detect the driver of a small part of drunk driving, and most of the drivers of drunk driving are all not checked, and the scope of inspection is very narrow, and the possibility of traffic accident is very big, and Unhygienic, easy to cause cross infection, poor humanization
