[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an oil filter.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The present invention discloses an oil filter, comprising an outer shell, a top cover is fixed on the top of the outer shell, an oil outlet penetrating the top cover is arranged on the top cover, oil inlets are evenly arranged on the top cover around the oil outlet, a filter element is fixed inside the outer shell, a bracket is fixed on the top of the filter element, a turntable rotatably connected to the bracket is arranged on the bracket, a plurality of guide plates are fixed on the turntable, a plurality of baffles are also fixed on the turntable, the baffles are arranged around the filter element, a partition is also fixed inside the outer shell, the partition is arranged around the filter element, a fixing plate is also fixed between the partition and the outer shell, a filter groove penetrating the partition is evenly arranged on the partition on one side of the fixing plate, and a plurality of inlets penetrating the partition are also evenly arranged on the partition. After the engine oil enters the housing through the oil inlet, it is filtered through the filter element. After the engine oil is filtered, it is supplied to the engine through the oil outlet. After the engine oil enters the housing, the engine oil contacts the guide plate spirally arranged on the turntable. The engine oil pushes the guide plate to move, so that the turntable rotates on the bracket. When the turntable rotates, the baffle rotates with the turntable, and impurities are blocked on the side of the baffle where the baffle contacts the partition. When the impurities move to the inlet position with the baffle, the impurities are pushed into the inlet. The impurities enter between the partition and the housing, which can effectively prevent impurities from adhering to the filter paper of the filter element, and can effectively extend the service life of the filter element.

[0008] Preferably, the guide plate is arranged on a turntable below the oil inlet, and the guide plate is spirally arranged on the turntable.

[0009] Preferably, the baffle is also evenly provided with filter holes penetrating the baffle.

[0010] Preferably, magnetic strips are fixed on the baffles, and the metal impurities are attracted by the magnetic strips, and the metal impurities are adsorbed on the magnetic strips, so as to prevent the metal impurities from piercing the filter paper on the filter element.

[0011] Preferably, a bottom plate is provided in the outer shell at the bottom of the filter element, and a spring is fixed in the outer shell below the bottom plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] When the device filters the engine oil, impurities in the engine oil can be pushed into the cavity between the partition plate and the shell for storage, which can effectively extend the service life of the engine oil filter. BRIEF DESCRIPTION OF THE DRAWINGS
