DETAILED DESCRIPTION

[0013] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0014] As shown in Figure 1 , Figure 2 , Figure 3 , the multi-layer filtering oil filter comprises an oil filter body 1, an oil inlet hole 2, an oil outlet hole 3 and a sealing cover 4, the oil inlet hole 2 is provided with a first filter layer 5 for rough filtering, the oil filter body 1 is provided with an annular mounting seat 6 connected with the inner wall of the oil filter body 1, the mounting seat 6 is in a stepped structure, a filter funnel 7 for fine filtering is arranged on the lowermost layer of the mounting seat 6, an adsorption filter layer 8 for secondary filtering is arranged on the filter funnel 7, an annular pressing plate 9 for limiting the filter funnel 7 and the adsorption filter layer 8 is arranged on the adsorption filter layer 8, and the mounting seat 6 divides the oil filter body 1 into an upper cavity 10 and a lower cavity 11.

[0015] In use, lubricating oil enters through the oil inlet hole 2, is roughly filtered by the first filter layer 5 to screen out large impurities in the lubricating oil, then enters the upper cavity 10, and flows into the adsorption filter layer 8 from the upper cavity 10, because the lubricating oil has a certain adsorption property, the adsorption filter layer 8 is in a conical structure, and a magnetic attraction part 14 for adsorbing metal is arranged at the lower end of the adsorption filter layer 8, a plurality of inclined oil filter holes 15 are arranged on the adsorption filter layer 8, so that the lubricating oil adhering to the adsorption filter layer 8 flows downward, flows to the magnetic attraction part 14 through the oil filter holes 15, the metal chips in the lubricating oil are adsorbed on the magnetic attraction part 14, and finally flow into the filter funnel 7 for fine filtering and are discharged from the oil outlet hole 3.
