AI Technical Summary

Technical Problem

The existing engine oil filter with multi-stage filtration function is not convenient to adsorb metal debris in lubricating oil, and metal debris can easily scratch the stacked filter paper, resulting in a reduced filter effect of stacked filter paper.

Method used

An oil filter including the first and second filter components is designed. The first filter component consists of a first stack of filter paper and a first annular magnet. The second filter component consists of a second stack of filter paper and a second annular magnet. The ring magnet absorbs iron filings in the lubricating oil to ensure that the iron filings do not scratch the filter paper.

Benefits of technology

The lubricant oil is filtered twice and the iron filings in the lubricant are adsorbed three times, which significantly improves the filtration effect, avoids the iron filings scratching the filter paper, and extends the service life of the filter.

Abstract

The utility model discloses an engine oil filter with a multi-stage filtering function, belongs to the technical field of engine oil filters, and solves the problems that an existing device is inconvenient to adsorb metal scraps in lubricating oil, the metal scraps are easy to scratch stacked filter paper, and then the filtering effect of the stacked filter paper is reduced. The middle of the inner wall of the outer shell is fixedly sleeved with a partition plate, the partition plate divides the left side and the right side of the interior of the outer shell into an oil inlet cavity and an oil outlet cavity, a first filtering assembly and a second filtering assembly are arranged in the oil inlet cavity and the oil outlet cavity correspondingly, and lubricating oil is filtered through the first filtering assembly and the second filtering assembly; the purposes of filtering the lubricating oil twice and adsorbing the scrap iron in the lubricating oil for three times are achieved, sufficient adsorption of the scrap iron in the lubricating oil is facilitated, the situation that the scrap iron scratches the first stack of filter paper or the second stack of filter paper is avoided, and the filtering effect of the first filtering assembly and the filtering effect of the second filtering assembly are improved.
