Among the figure: 1-gas collecting device, 11-negative pressure inlet device, 2-alcohol concentration tester, 3-controller, 4-relay, 5-switch, 6-digital display screen.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The device of driving when intoxicated that prevents that the utility model provides comprises:
Be used for the gas collecting device of the gas of collection automobilist exhalation, it is installed on the vehicle steering, and this gas collecting device is provided with the negative pressure inlet device;
For detection of the alcohol concentration tester of the alcohol concentration in the collected gas of gas collecting device, its input end is connected with the mouth of gas collecting device;
Be used for receiving the signal that the alcohol concentration tester is exported, and to its controller of handling back output control signal, its signal input part is connected with the signal output part of alcohol concentration tester;
Be used for receiving the signal that controller is exported, and make the path of circuit and the relay of the reaction of opening circuit according to this control signal, this relay is connected in the automobile oil supply circuit, and its signal input part links to each other with the signal output part of controller;
Be used for the path and the switch that opens circuit of the pull up circuit of control gas collecting device and alcohol concentration tester and controller, it is arranged in the key mouth of automobile starting switch.
Fig. 1 shows the structural representation that the utility model provides, and for convenience of explanation, this figure only provides the structure division relevant with the utility model.
Prevent that the device of driving when intoxicated from comprising:
Relay 4, it is series in the automobile oil supply circuit, the signal input part of relay 4 links to each other with the signal output part of controller 3, be used for receiving the signal that controller 3 is exported, and make the path of circuit and the reaction of opening circuit according to this control signal, the signal of the alcohol concentration in alcohol concentration tester 2 the gas that the gas collecting device that detects 1 is collected is passed to controller 3, if it is greater than setting value, then controller 3 is output signal, control relay 4 is made the reaction of opening circuit, cut off the automobile oil supply circuit, automobile can't be started because can not get fuel feeding because making automobile;
