Description

Technical Field

[0001] This utility model belongs to the technical field of alcohol detection instruments, and specifically relates to an alcohol detection instrument. Background Technology

[0002] A breathalyzer is an instrument used to detect whether a person has ingested alcohol and the amount of alcohol ingested. It can be used by traffic police to detect the amount of alcohol consumed by drivers, effectively reducing the occurrence of serious traffic accidents. It can also be used in other situations to detect the alcohol content in exhaled breath, preventing personal injury and significant property damage, such as in high-risk industries where employees are prohibited from working under the influence of alcohol.

[0003] Breathalyzers typically use semiconductor oxide sensors to detect alcohol vapor. When an oxide with N-type conductivity is exposed to the atmosphere, its resistance increases due to the adsorption of oxygen, reducing the number of electrons within it. If alcohol, a reducing gas, is present in the atmosphere, it reacts with the adsorbed oxygen, increasing the number of electrons within the oxide and causing its resistance to decrease. Breathalyzers analyze the alcohol concentration in the gas by measuring this change in resistance.

[0004] However, alcohol testing devices are easily dropped and damaged during use because users do not hold them securely.

[0005] This invention addresses the aforementioned problems by providing an alcohol detector that is designed to prevent it from falling off. Utility Model Content
