[0027] A motor 6 is provided in the pump housing 1 , and the motor 6 is connected to a rotating shaft 7 to drive the internal parts to work.

[0028] Furthermore, the port on one side of the pump housing 1 is inserted into and fixedly connected to one side of the inner housing 3, and the inner housing 3 and the pump housing 1 share the same center line. At the same time, the outer end of the rotating connecting shaft 7 passes through the inner housing 3, and a clamping groove 301 is opened in the other side of the pump housing 1.

[0029] Furthermore, the blade-shaped water retaining ring 9 is rotatably connected to the clamping slot 301, and the outer side of the blade-shaped water retaining ring 9 is provided with fan blades.

After the motor 6 drives the rotating shaft 7 to rotate, the impeller assembly 11 rotates accordingly, thus forming the internal workings of the water pump.

[0039] Working principle:

[0040] A motor 6 is provided in the pump housing 1, and a rotating shaft 7 is provided in the motor 6.

A positioning ring block 10 is provided in the inner housing 3, and a mechanical seal 8 provided in the middle of the positioning ring block 10 is sleeved on the outside of the rotating shaft 7. When the impeller assembly 11 starts to work, water flow is generated inside, which is first blocked by the mechanical seal 8 to prevent water from flowing into the pump housing 1. However, during long-term use, a certain amount of moisture will overflow from the mechanical seal 8 to the direction of the motor 6. At this time, the fan-shaped water retaining ring 9 on the rotating shaft 7 will rotate, and wind will be generated inside to discharge the moisture outside the bearing in the motor 6 in time, thereby preventing the bearing from being damaged by condensed water.
