Engine oil filter used for automobile engine

Abstract

The invention provides an engine oil filter used for an automobile engine. The engine oil filter comprises a shell, a bottom plate, a first filter element and a second filter element. A transverse partition plate divides the interior of the shell into a first filtering cavity and a second filtering cavity. The filter element is arranged in the first filtering cavity and comprises a first central pipe, a first filter paper set, a first end cover, a second end cover and a plurality of second central pipes. The multiple second central pipes are circumferentially distributed around the first central pipe with the first central pipe being the center. A plurality of filtering assemblies are arranged in each second central pipe at intervals in the vertical direction. Each filtering assembly comprises two filtering nets arranged oppositely. A plurality of magnet blocks are arranged between every two filtering nets. The second filtering element is arranged in the second filtering cavity. Metal impurities with various sizes are attached and filtered through of the multiple filtering assemblies in the second central pipes, so that the filtering pressure of the first filter paper set and a second filter paper set is reduced, the using periods of the first filter element and the second filter element are prolonged, and the filtering effects of the first filter element and the second filter element are improved.

Description

technical field [0001] The invention relates to the technical field of engine oil filters, in particular to an engine oil filter for automobile engines. Background technique [0002] The function of the oil filter is to filter the oil entering the main oil passage of the engine, so that the oil can reach a certain degree of cleanliness, and prevent the early abrasive wear of the moving parts in the engine due to impurities. When the engine is running, the oil with a certain pressure It enters the filter through the oil inlet hole, and after being filtered by the filter element assembly, it enters the lubricating mechanism of the engine through the oil outlet hole. But because this kind of oil filter can only filter out the impurities with larger particle size, it is difficult to filter out the wear impurities with smaller particle size, which also reduces the service life of the engine. Contents of the invention [0003] Based on the technical problems existing in the bac...
