[0003] In order to ensure the cooling and lubrication of various engine components, an electronic oil pump is needed to provide power for the oil circulation. The electronic oil pump is powered by an internal motor to drive the impeller (inner and outer rotors) to drive the oil circulation to cool and lubricate related components. According to different customer needs, such as high assembly temperature, the oil pump is required to perform appropriate heat dissipation or filtering functions on the oil. However, the current oil pump inlet and outlet are directly connected, and the flowing oil cannot be filtered or cooled, which cannot meet actual needs. Therefore, it is necessary to improve it. Summary of the invention

When working, the oil enters the oil pump body from the oil inlet pipe, flows out through the oil outlet pipe after circulation, the oil passes through the buffer before entering the oil inlet pipe, the oil enters the oil inlet cavity from the oil inlet, and flows into the oil inlet pipe after passing through the buffer filter structure, when the oil circulates, the fins can cooperate with the shell to take away the heat of the oil, the oil flows out around the partition plate, and the oil can be cooled without affecting the flow resistance of the oil.

[0006] Preferably, the oil inlet is located on the same side as the oil inlet pipe, and the oil inlet is opened on the same side as the oil inlet pipe, so as to cooperate with the buffer filter structure to cool the oil.

[0007] Preferably, the fins are radially distributed, and the direction of the fins in the upper housing is tangent to the oil inlet. The fins are in the shape of a sheet structure, and the fins can be a straight plate or an arc plate structure. The direction of the fins in the upper housing is tangent to the oil inlet, which can effectively reduce the flow resistance of the oil and can cooperate with the flow direction of the oil to cool the oil.

[0008] Preferably, the buffer filter structure comprises a detachable partition installed between the upper shell and the lower shell, and an oil guide hole is opened on one side of the partition. The function of the partition is to divide the oil inlet cavity into two cavities and increase the distance of the oil. The oil enters the oil inlet cavity from the oil inlet and flows along the partition to the oil guide hole.
