The disclosure relates to an electric liquid pump, comprising a pump housing, a motor connected to the pump housing, and an impeller housed in the pump housing and driven by the motor. The pump housing is provided with an inlet port and an outlet port. The impeller has an impeller inlet at the center thereof and an impeller outlet at a peripheral side thereof. The inlet port, the impeller inlet, the impeller outlet, and the outlet port are in flow connection sequentially. The inlet port comprises a columnar first segment and a second segment extending from the first segment. The second segment is close to the impeller inlet with a mouting seat formed therein. The impeller is sleeved on a rotation shaft. One end of the rotation shaft is engaged in the mounting seat. The impeller is rotatable relative to the mounting seat. The mounting seat is partially received in the impeller inlet. A gap between the mounting seat and an inner wall of the impeller inlet is defined as a flow passage for liquid.
