Description

Technical Field

[0001] The present invention relates to the technical field of breath alcohol concentration detection, in particular to a self-testing breath alcohol concentration detection device for intersections. Background Art

[0002] An alcohol tester is an instrument used to detect whether a person has consumed alcohol and the degree of alcohol consumed. It can be used by traffic police to detect the alcohol content of drivers during law enforcement, thereby effectively reducing the occurrence of major traffic accidents. It can also be used in other situations to detect the alcohol content in a person's exhaled breath to avoid casualties and significant property losses, such as in some high-risk areas where drunk drivers are prohibited from working. The idea of ​​not drinking and driving has been deeply rooted in people's hearts, but occasionally some unconscious people continue to drive after drinking, which leads to danger. Therefore, automatic alcohol detection devices are installed at the entrances of some urban roads. However, the current alcohol detectors need to be manually monitored at all times. Otherwise, the person being tested may blow slightly, causing the alcohol detector to not recognize whether he has been drinking, thus affecting the effectiveness of the automatic alcohol detection device.

[0012] The present invention has the following beneficial effects: The present invention fixes the telescopic component through a bottom plate. When the car driver needs to perform an alcohol test, the electric push rod is started to push the telescopic frame upward so that the alcohol detector can be moved to the height required by the car driver. At this time, the electric telescopic rod is started to push the telescopic frame to extend. The telescopic frame pushes the alcohol detector toward the driver when it is extended. When the alcohol detector moves to the driver's head, the driver can hold the pressure tube and pull the hose to extend. After the driver holds the arc-shaped air blowing nozzle in his mouth, an elastic bandage is put on the driver's head to fix the arc-shaped air blowing nozzle. At this time, the driver blows air into the interior of the arc-shaped air blowing nozzle, and the gas enters the interior of the alcohol detector through the fixing tube and the hose to perform alcohol testing, thereby improving the convenience of automatic alcohol testing.

[0013] In the present invention, the gas blown in by the driver enters the interior of the pressure tube, and the sealing block moves toward the outer end of the trachea by the pressure of the gas. The movement of the sealing block requires some air pressure as an aid. When the air pressure blown in by the driver is insufficient, the sealing block will not move. When the sealing block does not contact the pressure detector, the pressure detector will sound an alarm to remind the staff, so as to prevent the driver from evading alcohol detection by blowing lightly. When the driver stops blowing, the sealing block will enter the interior of the trachea through the elasticity of the elastic rod to seal the pressure tube so that the pressure tube can be used next time.

[0014] After the telescopic plate of the present invention is inserted into the interior of the jack frame through the positioning plate, the telescopic plate will limit the fixed tube through the circular hole frame, so that the fixed tube can limit the arc-shaped blowing nozzle through the circular hole frame, which is convenient for the driver to get the arc-shaped blowing nozzle for alcohol testing. When the telescopic frame is extended, it will push the telescopic plate to extend through the connection between the linkage plate and the circular hole frame, so that the telescopic plate can move synchronously with the pressure tube. After the driver finishes blowing, the positioning plate is inserted into the interior of the jack frame to contact with the stabilizing plate, and the jack frame is used to limit the pressure tube, which is convenient for its next use.

[0015] The pressure tube of the present invention is retracted and reset by the telescopic frame. When the end of the pressure tube corresponds to the rectangular frame, the electric rod is started to push the synchronization rod downward. When the synchronization rod moves downward, the rectangular frame is pushed to contact the surface of the arc-shaped air blowing nozzle. At this time, the telescopic frame continues to retract, and the rectangular frame will push the arc-shaped air blowing nozzle down, which is convenient for replacing the arc-shaped air blowing nozzle. The arc-shaped air blowing nozzle separated from the pressure tube will fall into the inside of the collection rack for storage, and the storage rack can store unopened arc-shaped air blowing nozzles for the convenience of the driver to replace them by himself.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
