This utility model relates to the field of fluid circulation system technology, specifically disclosing an electronic oil pump with an internal circulation flow control structure. The electronic oil pump includes a pump body with a cavity. The cavity is divided into an outer circulation cavity and an inner circulation cavity by a partition. The outer circulation cavity supplies oil to external oil-using equipment. The inner circulation cavity houses a motor and a controller, and the partition has an oil hole. The electronic oil pump also includes a one-way control unit located in the inner circulation cavity and connected to the partition. The one-way control unit covers the oil hole, enabling automatic adjustment of the oil flow channel opening based on oil pressure. The oil flow channel is the oil flow path formed by the oil hole and the one-way control unit. This solves the problem in the prior art where electronic oil pumps struggle to dynamically adjust the internal circulation flow according to actual operating conditions.
