Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods: Figures 1 to 7A novel three-way diverter valve is shown, comprising a valve body 1 with a cavity inside, in which a water diversion chamber 2 and a control chamber 3 are arranged from top to bottom, the water diversion chamber 2 is divided into two by a transversely arranged partition plate 20 to form an upper water chamber 21 and a lower water chamber 22, and the control chamber 3 is connected to the bottom of the lower water chamber 22; the valve body 1 comprises an upper shell 11, an intermediate shell 12 and a lower shell 13 stacked together from top to bottom, the upper water chamber 21 and the lower water chamber 22 are arranged in the upper shell 11 and the intermediate shell 12 respectively, the partition plate 20 is arranged on the top of the intermediate shell 12, and the control chamber 3 is arranged in the lower shell 13. Among them, a water inlet 4 connected to the upper water chamber 21 is arranged on the top of the upper shell 11, and an upper water outlet 23 connected to the upper water chamber 21 is arranged on the circumferential side wall of the upper shell 11. The intermediate housing 12 is connected to the upper water chamber 21 through a connecting hole 25 provided in the center of the partition plate 20. A lower water outlet 24 connected to the lower water chamber 22 is provided on the circumferential side wall of the intermediate housing 12. The water inlet end of the upper water outlet 23 is provided above the connecting hole 25 and coaxial with the connecting hole 25. A diverter plug 8 is movably provided in the connecting hole 25 and can be moved up and down to block the upper water outlet 23 or the connecting hole 25 respectively. A driving motor 6 that can drive the diverter plug 8 to move up and down is installed at the bottom of the lower housing 13. The motor shaft of the driving motor 6 extends into the bottom end of the control chamber 3. A connecting member 5 that converts the rotational force of the driving motor 6 into an up and down moving force is provided in the control chamber 3. The connecting member 5 is connected to the bottom end of the diverter plug 8.

[0027] Among them, Figures 2 to 7As shown in , the diverter plug 8 is in the shape of an “I”, the top of the diverter plug 8 is accommodated in the upper water chamber 21, the bottom of the diverter plug 8 is accommodated in the lower water chamber 22, and the top diameter of the diverter plug 8 is larger than the diameter of the connecting hole 25 and the water inlet end of the upper water outlet 23. A telescopic membrane 7 made of rubber material is transversely enclosed between the top of the control chamber 3 and the bottom of the lower water chamber 22, the bottom of the diverter plug 8 is connected to the telescopic membrane 7, and the top of the connecting member 5 abuts against the bottom of the telescopic membrane 7. When the diverter plug 8 in the shape of an “I” is pushed upward by the driving motor 6 through the connecting member 5, the top of the diverter plug 8 will block the water inlet end of the upper water outlet 23. At this time, the water flow entering from the water inlet 4 will enter the lower water chamber 22 from the upper water chamber 21 through the connecting hole 25, and finally be diverted out from the lower water outlet 24. When the diverter plug 8 is pulled downward by the driving motor 6 through the connecting member 5, the top of the diverter plug 8 will move downward away from the water inlet end of the upper water outlet 23 and block the connecting hole 25. In this way, the water flow entering the upper water chamber 21 from the water inlet 4 can only flow into the upper water outlet 23 from the water inlet end of the upper water outlet 23 and then be diverted out. It should be noted that in this embodiment, the telescopic membrane 7 includes a fixed disk 71 fixed between the top of the control chamber 3 and the bottom of the lower water chamber 22, a connecting block 72 is provided in the center of the fixed disk 71, and a deformable movable connecting part 74 is connected between the connecting block 72 and the fixed disk 71, and an embedding groove 73 is provided in the connecting block 72. The top of the embedding groove 73 is penetrated by a through hole 75 with a diameter smaller than that of the embedding groove 73. The bottom end of the diverter plug 8 passes through the through hole 75 and is clamped in the embedding groove 73.

[0028] In addition, since the driving motor 6 can only output a rotational force, it cannot directly push the telescopic membrane 7 upwards to make the diverter plug 8 move up and down. Therefore, a connecting member 5 for converting the rotational force of the driving motor 6 into an up and down moving force is provided in the control chamber 3 to make the diverter plug 8 move up and down. Figures 2 to 6As shown in , the connecting member 5 includes a tubular fixing member 51 provided in the control chamber 3, the top of the tubular fixing member 51 is closed, the bottom of the tubular fixing member 51 is open, the top of the tubular fixing member 51 is penetrated by a telescopic hole 52, a moving block 53 that can move up and down in the tubular fixing member 51 is movably provided in the tubular fixing member 51, the top of the moving block 53 is connected to a push rod 54 that can extend upward through the telescopic hole 52, the top of the push rod 54 is in contact with the center of the bottom surface of the telescopic membrane 7, and is used to push the connecting block 72 in the center of the telescopic membrane 7 upward, so that the diverter plug 8 can move upward. A reset spring 58 is sleeved on the push rod 54, the bottom end of the reset spring 58 is pressed against the top surface of the moving block 53, and the top end of the reset spring 58 is pressed against the top of the inner cavity of the tubular fixing member 51. A rotating block 61 is provided on the motor shaft of the driving motor 6, and a columnar matching cavity 55 is provided at the bottom of the moving block 53, which is concave upward. The rotating block 61 is movably embedded in the matching cavity 55, and a spiral groove 56 is symmetrically provided on the circumferential inner wall of the matching cavity 55, and a slider 57 that can be inserted into the corresponding spiral groove 56 is provided on the circumferential outer wall of the rotating block 61. Each slider 57 is a strip block with the same slope as the corresponding spiral groove 56. When the driving motor 6 is powered on and the motor shaft starts to rotate, the rotating block 61 will rotate synchronously with the motor shaft of the driving motor 6. At this time, the slider 57 on the rotating block 61 will squeeze the spiral groove 56 and drive the moving block 53 to move upward along the inner cavity of the tubular fixing member 51, so that the top rod 54 pushes the center of the bottom surface of the telescopic membrane 7 to realize the upward movement of the diverter plug 8. After the water entering the upper water cavity 21 from the water inlet 4 enters the lower water cavity 22 through the connecting hole 25, it is diverted out from the lower water outlet 24. When the driving motor 6 is powered off, the reset spring 58 pushes the moving block 53 to move downward along the inner cavity of the tubular fixing member 51. The top rod 54 leaves the center of the bottom surface of the telescopic membrane 7. After the telescopic membrane 7 loses its pushing force, the movable connection part 74 on it will deform and reset, thereby pulling the diverter plug 8 back downward. At this time, the top of the diverter plug 8 will cover the connecting hole 25 again, so that the water flow in the upper water cavity 21 will enter the upper water outlet 23 from the water inlet end of the upper water outlet 23 and flow out again.
