Problems solved by technology

Its shortcoming is that as long as there is alcohol in the car, the motor vehicle cannot be started, which is unacceptable to users and has no practicality; second, once the motor vehicle is started, drunk driving is still possible, and the real purpose of preventing drunk driving has not been achieved.

Embodiment Construction

[0010] Such as figure 1 , 2 As shown, the present invention includes an alcohol gas concentration detection, alarm, and breaker 1 and an alcohol gas concentration sensor 4. The alcohol gas concentration sensor 4 is electrically connected to the alcohol gas concentration detection, alarm, and breaker 1 signal input terminal. The alcohol gas concentration sensor 4 is fixed in the steering wheel 3 of the motor vehicle. The steering wheel 3 where the alcohol gas concentration sensor 4 is fixed has a detection vent. The steering wheel 3 at the detection vent is fixed with an air guide cup 5.

[0011] The air guide cup 5 has a flared opening, and the included angle of the flared opening is 30-60 degrees.

[0012] The material of the air guide cup 5 is a flexible material.

[0013] The model of the alcohol gas concentration sensor 4 is MQ-3.

[0014] Such as image 3 As shown, the alcohol gas concentration detection, alarm, and circuit breaker 1 includes single-chip microcomputer STC, indic...

Abstract

The invention relates to a motor vehicle drunk-driving-preventing device which comprises an alcohol gas concentration detection, alarm and breaking device and alcohol gas concentration sensors. The alcohol gas concentration sensors are connected with the signal input end of the alcohol gas concentration detection, alarm and breaking device and fixed inside a steering wheel of a motor vehicle. Detection gas holes are formed in the positions, where the alcohol gas concentration sensors are fixed, of the steering wheel. Gas guiding leather cups are fixed at the positions, where the detection gas holes are formed, of the steering wheel. The motor vehicle drunk-driving-preventing device is simple in structure, convenient to install and capable of truly achieving the drunk-driving-preventing aim.

Description

Technical field [0001] The invention relates to an anti-drunk driving device, which is particularly suitable for motor vehicles. Background technique [0002] With the development of the economy, people are engaged in more and more foreign affairs activities, because drunk driving has become a kind of helplessness, leading to frequent drunk driving accidents. To this end, there are a number of patent applications, such as the invention patent with application number 201110187675.8, which discloses an anti-drunk driving power-off device that uses an alcohol detection chip to determine whether the air in the cab contains alcohol to control the ignition circuit. One of its shortcomings is that as long as there is alcohol in the car, the motor vehicle cannot be started, which is unacceptable to users and has no practicality; second, once the motor vehicle is started, it can still be driven under the influence of alcohol, which does not achieve the real purpose of preventing drunk dri...
