Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 , 2 Shown: a fully automatic piston-type sweat collection chamber, including a fingerprint reader 1, the fingerprint reader 1 is installed in a piston detector 2, the piston detector 2 is also installed with a screw-type piston 3, the The front portion of the piston detector 2 is a detection chamber 2a, and the rear portion is a motor chamber 2b. A motor 4 is installed in the motor chamber 2b. A gear 5 is fixed on the output shaft of the motor 4. The tooth surface of the gear 5 is in line with the The screw rods of the screw piston 3 are engaged, and the piston head of the screw piston 3 extends into the detection chamber 2a, and the piston head also coincides with the front opening of the detection chamber 2a, and the fingerprint reader 1 is fixed on the the lower bottom of the detection chamber 2a;

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 ofidentity.

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...
