Oil filter

Abstract

The invention relates to an oil filter, and belongs to the field of filters. The oil filter comprises a cylindrical shell body, a lower end cover is arranged at the lower end of the cylindrical shell body, a bypass valve is arranged on the lower end cover, the bypass valve is sealed in the shell body through a lower shell body, an upper end cover is arranged at the other end of the cylindrical shell body, a check valve is arranged on the upper end cover, the check valve is sealed in the shell body through an upper shell body, an engine oil outlet is formed in the middle of the upper shell body, an engine oil inlet is formed around the engine oil outlet, and the position of the engine oil inlet corresponds to the position of the check valve. A filter core is arranged in the shell body, a keel frame is arranged at the hollow position of the filter core, one end of the keel frame is in sealing connection with the upper end cover, the other end of the keel frame is in sealing connection with the lower end cover, the keel frame is a modular keel frame, a concave spigot and a convex spigot which are of the same specification are formed in the head end and the tail end of each module respectively, the adjacent modules are in cooperation through the concave spigots and the convex spigots, filter holes are formed in the keel frame, the shell body and the lower shell body are integrally formed, and are made of transparent plastic materials, and high efficiency and environmental protection are achieved.

Description

technical field [0001] The invention relates to an engine oil filter, which belongs to the field of filters. Background technique [0002] During the working process of the engine, metal wear debris, dust, carbon deposits and colloidal deposits oxidized at high temperatures, 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 prolong its service life. The end caps of the commonly used filters are iron caps, which are easy to scratch. The process requires multiple riveting, spot welding, and gluing, and the exterior needs to be painted, which pollutes the air, is inefficient and labor-intensive, and wastes a lot of time. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is to provide an efficient and environment-friendly engine oil filter. ...
