Description

TECHNICAL FIELD

[0002] In the prior art, in the running process of the engine, impurities in the engine oil need to be filtered through the engine oil filter to avoid damage to the internal structure of the engine. The traditional engine generally uses a paper filter element type engine oil filter. The paper filter element type engine oil filter can at most filter out 60% of the impurities in the engine oil. However, in actual use, 40% of harmful impurities cannot be effectively filtered out by the paper filter element. Among the 40% of impurities, ferromagnetic impurities are the most. These ferromagnetic impurities circulate with the engine oil into various lubricating oil channels, which reduces the lubricating ability of the engine oil, increases the wear of parts, and even damages the engine. That is, the traditional engine oil filtering device is limited by the structure and cannot achieve good filtering effect, especially for ferromagnetic substances in the engine oil. If a better filtering effect is to be achieved, the traditional engine oil filtering device often increases many filtering devices, resulting in a large size, a complex structure, inconvenience for installation and use, and high cost, which does not meet the current increasingly stringent requirements for energy saving and environmental protection.
