Embodiment Construction

[0037] The following is attached Figure 1-7 The application is described in further detail.

[0038] The embodiment of the present application discloses an airless pump type alcohol tester.

[0039] refer to figure 1 , an airless pump type alcohol tester, comprising an airflow channel 1, the airflow channel 1 is arranged inside the alcohol tester, and is used to provide a path for the gas sample collected by the alcohol tester to flow into and out of the alcohol tester, and the airflow channel 1 is provided with a useful For the pumping assembly driven by the flow of the gas sample, the pumping assembly includes two one-way doors 21 fixed on the inner wall of the gas flow channel 1. The one-way door 21 is in the shape of a sheet and made of PET material. The doors 21 are all semicircular and symmetrically arranged. The one-way doors 21 in the airflow channel 1 are gradually inclined to the gas flow direction from the direction close to the inner wall of the airflow channel ...

Abstract

The invention relates to the technical field of law enforcement detection equipment, in particular to an air-pump-free type alcohol tester and a detection circuit, and aims to overcome the defects that in the prior art, when an air pump is used for extracting air for alcohol detection, the suction amount of air suction of the air pump is too large, too much air is easily sucked, and the error of an alcohol detection result is large. According to the technical scheme, the air-pump-free type alcohol tester comprises an airflow channel used for enabling air to circulate, an air pumping assembly used for pumping air is arranged in the airflow channel and comprises two symmetrically-arranged one-way doors, and the two one-way doors are fixed to the inner side wall of the airflow channel and are arranged to seal the airflow channel when the two one-way doors are static, the one-way doors are arranged to point to the air outlet from the air inlet of the airflow channel, the two one-way doors are each provided with a vibration generation element, and the product has the advantages that errors caused by the fact that a detection result is affected by air during alcohol detection are reduced, and the accuracy of the detection result is improved.

Description

technical field [0001] The application relates to the technical field of law enforcement detection equipment, in particular to an airless pump type alcohol tester and a detection circuit. Background technique [0002] Drunk driving refers to the behavior of a driver driving a vehicle on the road after drinking alcohol. According to the accident survey of the World Health Organization, about 50%-60% of traffic accidents are related to drunk driving. Drunk driving has been listed as a Leading cause of death in car accidents. [0003] In recent years, traffic police usually use alcohol tester to detect the alcohol content in the driver's exhaled breath as the basis for investigation and punishment when investigating and punishing drunk driving. The subject blows gas through the mouthpiece of the alcohol tester, and then analyzes the alcohol concentration through the alcohol detection module in the alcohol tester. [0004] At present, the alcohol detection module of a common a...
