Abstract

The invention relates to the technical field of oil filters, and discloses an automatic internal cleaning engine oil filter. The automatic internal cleaning engine oil filter comprises a shell, a bypass valve is fixedly installed at one end of the interior of the shell, a containing opening is formed in the center of one end of the exterior of the bypass valve, a prestress convex top is fixedly installed at the center of one end of the exterior of the bypass valve, and a plurality of bypass openings are formed in the other end of the prestress convex top. After being filtered for the first time, engine oil flows into a gap between the strong magnet and the paper filter element and is magnetically adsorbed by the strong magnet, and metal particles contained in the engine oil are adsorbed to the strong magnet, so that the metal particles contained in the engine oil are removed for secondary filtering treatment, the multi-stage filtering treatment structure is added, impurities contained in engine oil are all filtered out, abrasion of the interior of the engine caused by the impurities such as metal particles is avoided, and the service life of the engine is prolonged.

Description

technical field

[0001] The invention relates to the technical field of engine oil filters, in particular to an engine oil filter for automatic internal cleaning. Background technique

[0002] Oil filter, also known as oil grid. It is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. The oil filter can be divided into full-flow type and split-flow type. The full-flow filter is connected in series between the oil pump and the main oil passage, so it can filter all the lubricating oil entering the main oil passage. The split-flow filter and The main oil passages are connected in parallel, and only part of the lubricating oil sent by the oil pump is filtered. When using the full-flow filter, there are the following problems: 1. Most of the existing oil filters are a single paper filter element filter structure, which is limited by the size of the filter holes of the paper filter element, and impurities...
