Engine oil filter assembly and assemble method and disassembly method thereof

Abstract

The invention discloses an engine oil filter assembly. The engine oil filter assembly comprises an engine oil filter and an installation base, wherein the engine oil filter is used for filtering engine oil, the installation base is used for supporting the engine oil filter, an oil return control mechanism is arranged inside a cavity of the installation base, the engine oil filter is installed on the oil return control mechanism through a connecting pipe, the oil return control mechanism comprises an oil return device body and a sealing face cavity, an oil outlet which is connected with a filtered engine oil outlet pipeline during installation of the engine oil filter is arranged on the oil return device body, an oil return opening which is connected with an oil return pipe during disassembly of the engine oil filter is arranged on the sealing face cavity, an oil return spring which is fixedly connected with the oil return device body is arranged inside the sealing face cavity, the top end of the oil return spring is connected with the oil return device body, and the bottom end of the oil return spring extends out of the sealing face cavity and presses against the bottom face of the cavity of the installation base. The invention also provides an assemble method and a disassembly method of the engine oil filter assembly. The engine oil filter assembly has the advantages of being simple in structure, reliable to operate and high in strength and is applicable to engine oil filtering and oil returning of the engine oil of various engine oil engines.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to a device for providing clean engine oil for components such as a vehicle engine and a disassembly method thereof, in particular to an engine oil filter assembly and an assembly method and a disassembly method thereof. Background technique [0002] With the development of engine technology, more and more oil filter oil return control mechanisms in the oil filter assembly appear in various models, and the oil return methods are also various. From the perspective of the form of the oil filter, there are generally two types: spin-on type and detachable type. At present, the oil filter oil return control mechanism used for the spin-on oil filter is mostly sealed with a sealing ring. The oil return control mechanism does not rotate with the rotation of the oil filter, but is connected to the oil filter through a spring. The action of the pipe (or oil filter) makes the oil return control mecha...

AI Technical Summary

Problems solved by technology

However, the body of the existing oil filter oil return control mechanism is mostly plastic, which is sealed by a sealing ring, and the aging of the oil return control mechanism is relatively fast; When the oil filter oil return control mechanism is aging and fails, the accompanying oil leakage phenomenon is not easy to be found, and it is easy to cause serious accidents

[0004] In addition, since the current oil filter oil return control mechanism mostly moves up and down to open or close the oil return port, this control method accelerates the wear of the sealing ring, and the life of the oil filter oil return control mechanism is relatively short

Due to the up and down movement of the oil filter control mechanism, when there is a lot of residual oil in the oil filter and the oil filter seat, the oil has no time to flow away from the oil return port, and there is a risk of overflowing from the edge of the oil filter seat. , is also prone to accidents
