The upper cavity channel b1 of the tank body is communicated with the lower valve holes f2, f3, f4, and the lower cavity channel b2 of the tank body is communicated with the lower valve holes f1, f5, f6.

[0027] In Figure 2In it, ceramic rings 7 that fit and seal are respectively provided on the upper and lower sides of the planetary gear open 8 and the planetary gear closed 11. A sealing ring 6 is provided below the ceramic ring 7, and they are respectively installed in the corresponding upper valve holes h1, h2, h3, h4, h5, h6 of the upper valve 4 and the lower valve holes f1, f2, f3, f4, f5, f6 of the lower valve 9.

[0028] In Figure 1 it, a first Hall sensor 14 and a second Hall sensor 15 are provided on the upper valve 4. When the first Hall sensor 14 and the second Hall sensor 15 receive the magnetic signal of the magnet 12 on the planetary gear closed 11, it is transmitted to the controller 16, and the controller 16 sends an instruction to stop the motor 1, and the control valve station switching ends. As Figure 7 shown, the models of the first Hall sensor 14 and the second Hall sensor 15 are T4102A. The model of the controller 16 selected in the present invention is the 15F408AS single-chip microcomputer. The P1.4 pin and P1.5 pin of the 15F408AS single-chip microcomputer are electrically connected to the first Hall sensor 14 and the second Hall sensor 15, and the P1.0 pin of the 15F408AS single-chip microcomputer is electrically connected to the motor 1.

The sun gear 10 simultaneously meshes with two planetary gear opens 8 and four planetary gear closed 11 to rotate. The two planetary gear opens 8 and four planetary gear closed 11 are the planetary gears. All the planetary gears rotate around the axis of the sun gear 10. When all the planetary gears rotate to the upper valve holes h1, h2, h3, h4, h5, h6, they stop, realizing the closing of the channels at the positions of the corresponding planetary gear closed 11 and the opening of the channels at the positions of the planetary gear open 8. The two planetary gear opens 8 and four planetary gear closed 11 mesh with the internal teeth c of the upper valve 4 during the rotation process. The model of the motor 1 is TH37JB32-c.

[0030] In the embodiment of the present invention, when the sun gear 10 rotates counterclockwise for switching, the control valve for the filtration process is realized, so as to realize backwashing, normal washing, and operation.
