Description

Technical Field

[0001] This patent relates to the technical field of fuel dispensers, specifically a multi-layer protective anti-static device. Background Art

[0002] Gas stations refer to refueling stations that sell gasoline and motor oil for cars and other motor vehicles, usually for adding fuel oil, lubricants, etc. Static electricity is a static charge. When refueling vehicles at gas stations, the presence of static electricity makes the refueling process more dangerous. Therefore, anti-static equipment is needed to improve the safety of vehicle refueling.

[0003] However, the anti-static device of the refueling machine in the prior art only removes static electricity through water mist, but does not take into account the changes in airflow in the refueling environment. As a result, when wind blows in the environment, the airflow will drive the water mist to move, resulting in changes in the coverage area of ​​the water mist, thereby affecting the anti-static effect. Therefore, the prior art needs to be improved. Utility Model Content
