Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0025] An alcohol tester, the alcohol tester includes a housing, a circuit board is installed in the housing, an alcohol sensor and a display screen for displaying information are installed on the circuit board, and the housing includes The arc-shaped design of the diversion part is provided with a blowing hole and an air outlet hole on the diversion part. The alcohol sensor is arranged in the diversion part. Drain to the alcohol sensor and guide the discharge of gas very effectively, making operation and use very convenient. When in use, by blowing air from the blowing hole, the gas passes through the diversion part to make the gas pass through the alcohol sensor. The alcohol content is detected, and the detection result is displayed on the display screen, which is convenient for reading and recording the alcohol content value. It is very con...

Abstract

The invention discloses an alcohol tester. The alcohol tester comprises a shell; a circuit board is arranged in the shell; the circuit board is provided with an alcohol sensor and a display screen used for displaying information; the shell comprises a flow guide part with an arc design; blow holes and air outlets are formed in the flow guide part; the alcohol sensor is arranged in the flow guide part; by arc setting of the flow guide part, a to-be-tested gas is guided to the alcohol sensor very effectively, and is guided to be discharged very effectively, so that operation and use is very convenient.

Description

technical field [0001] The invention relates to the field of alcohol testing devices, in particular to an alcohol testing device. Background technique [0002] When the alcohol tester works, it uses the electrochemical principle to select the alcohol sensor, which is a test component sensitive to alcohol. When the alcohol sensor encounters alcohol molecules, its conductivity changes rapidly to generate a voltage or current signal. After the signal is amplified by the circuit, it is calculated with a dedicated integrated chip. The result of this change after processing is displayed on the tester. [0003] Using the feature of alcohol sensor, the alcohol tester can quickly detect the blood alcohol concentration of the human body after drinking. After the user tests, he can know whether the alcohol concentration in his body and blood exceeds the standard. When it exceeds the standard value, he warns the driver not to drive, which can be greatly improved. Reducing the occurrenc...
