One end of the spring 10 is fixedly connected to the valve body 8, and the other end is fixedly connected to the valve core 9. A limit ring 11 is fixedly connected to the valve body 8. A first key 4 is provided at the top of the second cam 18, and a second key 24 is provided inside the second impeller 14. Both the first key 4 and the second key 24 are located at the output end of the motor 1. A first sealing ring 3 is installed on the upper surface of the motor 1, and the first sealing ring 3 is located on the lower surface of the first housing 21. A second sealing ring 3 is installed on the upper surface of the first housing 21. Three sealing rings 17 are provided, with the third sealing ring 17 located on the lower surface of the second housing 22. A second sealing ring 15 is installed on the upper surface of the second housing 22 and is located on the lower surface of the top housing 19. A connecting post 23 is fixedly connected to the outer wall of the first housing 21 and is fixedly connected to the outer wall of the second housing 22.

[0019] Working principle: When using this invention for water conveyance, firstly, when the motor 1 is controlled to rotate clockwise, it drives the second impeller 14 to rotate. Water flows into the limiting ring 11 from the inlet pipe 20. The rotor floats outward, causing the first impeller 7 on the output end of the motor 1 to engage with the first cam 2, and the third impeller 16 to disengage from the second cam 18. The first impeller 7 rotates, and the third impeller 16 does not rotate. Water is then discharged outward through the one-way valve of the first outlet pipe 12, and no water is discharged from the second outlet pipe 13. When a circuit needs to be changed, the motor 1 can be controlled to rotate counterclockwise, causing the rotor to float inward. This causes the first impeller 7 on the output end of the motor 1 to disengage from the first cam 2, and the third impeller 16 to engage with the second cam 18. The third impeller 16 rotates, and the first impeller 7... If 7 does not rotate, the first outlet pipe 12 will not discharge water, and the water will be discharged outward through the one-way valve of the second outlet pipe 13. The one-way valve is composed of valve body 8, valve core 9, and spring 10. The first sealing ring 3 is used to improve the sealing at the connection between motor 1 and first housing 21. The first key 4 on the output end of motor 1 fixes the second cam 18. The blocking ring 5 and fixing ring 6 play a limiting role. The second sealing ring 15 is used to improve the sealing at the connection between the first outlet pipe 12 and second outlet pipe 13. The third sealing ring 17 is used to improve the sealing at the connection between top shell 19 and second housing 22. The connecting post 23 of the first housing 21 is used to connect the second housing 22. The second key 24 is used to fix the second impeller 14 on the output end of motor 1.
