[0002] Fuel pump is a professional term in the automotive parts industry. It is one of the basic components of the fuel injection system of electronic fuel injection vehicles and is mainly used in the transportation equipment industry. Located inside the vehicle's fuel tank, the fuel pump works when starting and the engine is running. If the engine stops and the ignition switch is still on, the control module turns off the power supply of the fuel pump to avoid accidental ignition. When the fuel pump sucks out the fuel in the car tank, an oil and gas coarse filter device is required to ensure the cleanliness of the gasoline supply. For example, as shown in a fuel pump oil and gas coarse filter device with Chinese patent application number CN201922375749.5, a threaded groove is opened on the side of the sealing cover, and the oil and gas filter element is located in the oil and gas filter cylinder, and one end of the oil and gas filter element is connected to the filter element interface, and the filter element interface is threadedly connected to the threaded groove. When there are many impurities in the oil and gas filter element, the oil and gas filter cylinder can be unscrewed, and then the oil and gas filter element can be removed from the filter element interface by rotating, and the oil and gas filter element can be directly replaced.

[0003] However, due to the threaded cooperation between the filter element interface and the sealing cover, the sealing cover is removed from the oil and gas filter cylinder to facilitate the removal of the filter element from the filter cylinder. In the process of replacing the filter element, it is not only time-consuming and laborious, but also not conducive to the use of the oil and gas coarse filtering device. Utility Model Content
