Problems solved by technology

[0005] But this kind of traditional machine oil filter device is when changing machine oil, and the inside of filter is full of machine oil, if install upwards, when unscrewing filter, machine oil can flow out from the hole in the middle of filter, to replace The oil brings troubles; at the same time, because the traditional oil filter device is an assembly of filter elements, check valves, bypass valves, and springs, it needs to be replaced as a whole; but only the filter element fails, and the overall replacement has caused Waste of resources, increased maintenance costs

Embodiment Construction

[0034] The core of the present invention is to provide an engine oil filter device. During disassembly, the internal oil flows into the engine body, so that the problem of oil leakage in the engine oil filter device does not occur, and the installation limitation of the oil filter device is eliminated. Another core of the present invention is to provide an engine comprising the above-mentioned oil filter device.

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] Please refer to Figure 2 to Figure 5 , figure 2 The general assembly drawing of the oil filter device provided by the present invention;

Abstract

The invention discloses an engine oil filtering device of an engine. The engine oil filtering device comprises a shell and a filter element. The shell is installed on an engine body of the engine. The filter element is arranged in an inner cavity of the shell. The shell is provided with an oil leakage channel communicating an inner cavity of the engine with the inner cavity of the shell. The oil leakage channel comprises a first channel and a second channel. The first channel is large in inner diameter and close to the filter element. The second channel is small in inner diameter and away from the filter element. A push rod is movably installed in the oil leakage channel in the axial direction. One end of the push rod is connected with the filter element in an abutting mode. The push rod comprises a protrusion portion. The protrusion portion is larger than other parts of the push rod in outer diameter. The side wall of the protrusion portion is attached to the inner wall of the second channel. In the detaching process of the engine oil filtering device, internal engine oil flows into the engine body of the engine, leakage of engine oil in the engine oil filtering device is avoided, and installing limitation of the engine oil filtering device is eliminated.

Description

technical field [0001] The invention relates to the technical field of prime movers, in particular to an engine oil filter device. The present invention also relates to an engine comprising the above-mentioned engine oil filter device. Background technique [0002] The various components in the engine need to be lubricated by engine oil to achieve normal work, but metal debris generated during the operation of the components, dust entering, carbon deposits oxidized at high temperatures, and some water vapor will continue to be mixed into the engine oil. The existence of these impurities It will shorten the service life of the engine oil and even affect the normal operation of the engine. In order to filter the impurities in the engine oil and prolong the service life of the engine oil, an oil filter device is usually installed in the engine. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a traditional oil filter device. [0004] The...
