AI Technical Summary

Technical Problem

When used, existing alcohol detectors are prone to poor airflow due to misalignment between the driver and the instrument, resulting in errors in detection results, and it is difficult to quickly clean up residual alcohol molecules, affecting the accuracy.

Method used

A back clip type alcohol detector is designed. By setting end air holes and side air holes on the main housing, and installing a trigger valve and fan inside, the fan actively sucks the gas blown by the driver, and through a specific air flow path and valve structure, alcohol detection and cleaning is achieved.

Benefits of technology

The design enables accurate alcohol detection when the driver's mouth is not aligned with the instrument, and quickly cleans up residual alcohol molecules by heating air, improving detection accuracy and cleaning efficiency.

Abstract

The invention relates to the field of alcohol detection, and discloses a back splint type alcohol detector which comprises a main shell, an end air hole is formed in the end of the main shell, a side air hole is formed in the side face of the main shell, an alcohol detection mechanism is installed in the main shell, the alcohol detection mechanism comprises a trigger valve, the trigger valve comprises a valve shell, and a valve element is arranged in the valve shell in a sleeved mode. A first side nozzle, a second side nozzle, a third side nozzle and a fourth side nozzle are arranged on the outer surface of the valve shell, a first valve groove and a second valve groove are formed in the outer circle face of the valve element, at the beginning, the first valve groove is used for communicating the first side nozzle with the second side nozzle, the second valve groove is used for communicating the third side nozzle with the fourth side nozzle, and after the valve element rotates by 90 degrees, the first valve groove is used for communicating the second side nozzle with the third side nozzle. The second valve groove is used for communicating the fourth side nozzle with the first side nozzle, the first side nozzle is communicated with the end air hole, the tail end of the second side nozzle is connected with a fan, the side air hole is communicated with the third side nozzle, and a detection assembly is arranged between the fourth side nozzle and the air outlet end of the fan.
