Embodiment Construction
[0030] The invention will be described in detail below in conjunction with the accompanying drawings.
[0031] Such as Figure 1-3 As shown, a water pump control system includes a casing, a motor, and a water pump impeller 30 . The rotating shaft 10 of the motor is vertically arranged, and the water pump impeller 30 is set at the bottom of the rotating shaft. The bottom end of the rotating shaft 10 stretches into the water inlet chamber 40, and a cone-shaped clutch ring 11 is fixed at the free end at the bottom of the rotating shaft.
[0032] A drainage ring 50 is fixed on the inner bottom of the water inlet chamber 40 . The drainage ring 50 includes a cylindrical barrel 51 , an inverted cone ring 52 and a plane ring. The cylindrical barrel 51 is coaxial with the rotating shaft 10 . The cylindrical barrel 51 is coaxial with the inverted cone ring 52, the top edge of the cylindrical barrel 51 is sealed and fixed with the bottom edge of the inverted cone ring 52, the top edge ...
