[0013] The cylindrical impeller body of the utility model is made of high-strength PPO plastic. During the injection molding process, the impeller copper sleeve is inlaid with the processed impeller copper sleeve and then integrally injection molded. A concave plane is cut on the surface of the impeller copper sleeve.
