Abstract
The invention relates to the technical field of water pumps, and discloses an electronic water pump. The electronic water pump comprises a pump cover (1), a front cover (2), a pump case (3) and a bottom cover (4) which are sequentially connected from top to bottom. A working cavity (5) is formed between the pump cover (1) and the front cover (2). An impeller (6) is arranged in the working cavity (5). A pump shaft (7) disposed at the center of the pump case (3) is arranged inside the pump case (3). The upper end of the pump shaft (7) is connected with the impeller (6) and further drives the impeller (6) to rotate synchronously. A center through hole (8) is formed in the middle of the pump shaft (7). The upper end of the center through hole (8) communicates with the working cavity (5), and the lower end of the center through hole (8) communicates with the inside of the pump case (3). A water inlet (9) which forms an integrated structure with the pump cover (1) is formed in the upper sideof the pump cover (1) and further communicates with the working cavity (5). According to the electronic water pump, radiation to a rotor by working media is reinforced by designing an internal circulation flow pass, and meanwhile impurities inside a shielding sleeve can be better discharged.
