an oil filter

Abstract

The present invention provides an engine oil filter, which includes a housing, a filter element arranged in the housing, and a controller. A base is provided in the housing, an oil inlet is provided on the base, and an oil outlet is provided on the side of the housing away from the base. The oil inlet is provided with a first backflow suppression device, and the oil outlet is provided with a second backflow suppression device; the filter element includes a first filter element and a second filter element, and the end of the first filter chamber near the oil inlet is provided with a slag discharge port; A filter element is provided with a detection device for detecting the thickness of the filter residue on the first filter element, the detection device is connected to the controller, the first filter chamber is provided with a cleaning device for cleaning the filter residue on the first filter element, and the controller is connected to the cleaning device. When the present invention is used, the engine oil enters the filter from the oil inlet, and is filtered through the first filter element and the second filter element in turn, which can effectively filter out impurities in the engine oil; the first backflow suppression device and the second backflow suppression device can effectively To prevent oil backflow, the filter residue on the first filter element can be quickly cleaned.

Description

technical field [0001] The invention relates to the technical field of engine oil filters, in particular to an engine oil filter. Background technique [0002] The main function of the engine oil is to minimize the impurities generated by friction of various components during operation, reduce energy loss and wear of parts. After the engine has been working for a long time, a large amount of iron filings and other abrasives will be produced, and these abrasives will enter the engine oil. Therefore, this part of the recycled engine oil must be filtered so that the recycled engine oil after removing impurities can be reused. At present, the engine oil used in automobile engines is generally filtered through a filter. Its function is to remove impurities such as dust, carbon deposits and soot particles in the engine oil, especially metal particles such as iron filings, so as to ensure that clean engine oil is supplied to the crankshaft, Connecting rods, camshafts, supercharger...

AI Technical Summary

Problems solved by technology

[0003] The filter element of the existing oil filter is generally a filter screen. When filtering the oil, the oil is passed into the filter screen, and the impurities are left on the bottom surface of the filter screen. During the filtering process, only the bottom surface of the filter screen To filter the engine oil, the filter area is small, and the bottom of the filter screen acts for a long time, the filter residue is not easy to remove, and it is easy to block, which affects its normal use
