Description

Technical Field

[0001] The utility model relates to the technical field of oil filters, in particular to an oil filter that can effectively remove metal particles. Background Technique

[0002] The oil filter is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles in the oil to protect the engine. During the operation of the engine, metal filings, dust, carbon deposits and colloidal precipitates oxidized at high temperature, water, etc. are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean, and extend its service life. The oil filter should have the properties of strong filtering ability, small flow resistance, and long service life.

[0003] For example, the authorized announcement number "CN204827593U" is an oil filter.

However, this filter is not convenient for disassembly, maintenance and repair; at the same time, the strong magnet is arranged inside the inner filter element. After the strong magnet adsorbs metal debris for a long time, it is easy to become congested, reducing the service life of this filter. Content of the Utility Model
