Description

Technical Field

[0001] The utility model relates to the field of ethanol detection equipment, in particular to a high-precision handheld ethanol detector. Background Art

[0002] The working principle of the ethanol detector is mainly to detect alcohol gas in the air through a gas sensor, and to detect the alcohol content by measuring the level change of the circuit. When the gas sensor cannot detect alcohol, the level added to a certain pin is low; when the gas sensor detects alcohol, its internal resistance becomes low, so that the level of a certain pin becomes high. The display driver determines the number of LEDs to be lit in sequence according to the level of a certain pin. The higher the alcohol content, the greater the number of diodes to be lit.

[0003] When the tester uses a handheld ethanol detector to detect whether the person being tested has been drinking, the person being tested needs to blow air into the testing area with his mouth. When blowing air from the mouth, the gas blown out will be accompanied by a large amount of saliva and breath. After multiple tests, the tested area will be contaminated with a large amount of saliva. The saliva contaminated on the testing area will accumulate for a long time and adhere to the surface of the tested area, which will not only affect the hygiene of the testing instrument, but also cause the detection accuracy of the testing area to decrease, and even lead to the transmission of some diseases. For this reason, we propose a high-precision handheld ethanol detector. Utility Model Content
