In this embodiment, as shown in fig. 12 and 13, the angle Φ between the central symmetry plane (also called as "central axis plane", hereinafter the same) M1 of the first key set 412 and the central symmetry plane M2 of the second key set 413 in the axial projection is 45 0 . In other embodiments, for example, where the valve body has 2 or 3 water outlet openings in the first and second sealing surfaces, Φ may also have a value of 90 0 Or 60 0 . In other embodiments, the first key set 412 and the second key set 413 are not circumferentially offset by an angle, i.e., the central symmetry plane M1 of the first key set 412 and the central symmetry plane M2 of the second key set 413 are axially offsetThe included angle phi on the projection drawing is zero, and at this time, the structures of the first opening and closing piece and the second opening and closing piece cannot be the same, and the axial through holes of the first opening and closing piece and the second opening and closing piece need to be staggered by an angle phi on the axial projection drawing. In this way, when the rotating shaft drives the first opening and closing member and the second opening and closing member to rotate at the same time, different valve body fluid waterways can be selected to conduct or not conduct, so that the function of conducting fluid to the valve body water outlet hole from the first water inlet pipe 103 or the second water inlet pipe 203 is realized.
Referring to fig. 4, a driving member 500, preferably a stepper motor, is fixedly mounted at the front end of the valve body 300, and a motor shaft of the stepper motor is connected to the rotating shaft 410.

In the image of fig. 15, the first shutter 420 and the second shutter 430 rotate 22.5 ° in the clockwise direction, and reach a rotation phase of 22.5 °, at this time, the axial through hole 421 of the first shutter 420 is not aligned with the water outlet hole of the first sealing surface 310, and the axial through hole 431 of the second shutter 430 is not aligned with the water outlet hole of the second sealing surface 310, at this time, both ends of the shunt valve 32 are not conducted.
In the image of fig. 16, the first shutter 420 and the second shutter 430 continue to rotate 22.5 ° in the clockwise direction, reaching a rotation phase of 45 °, at which time the axial through hole 421 of the first shutter 420 aligns with the water outlet hole 312 of the first sealing surface 310, forming a fluid flow path from the first water inlet pipe 103 into the first water inlet chamber 101, through the axial through hole 421 of the first shutter 420 into the first sealing surface water outlet hole 312, and then into the water outlet pipe 332; the axial through hole 431 of the second opening and closing member 430 is not aligned with the water outlet hole of the second sealing surface 310, and fluid is not conducted.
It is contemplated that as the first and second shutters 420 and 430 continue to rotate in a clockwise direction, different rotational phases are reached, such as 67.5 °, 90 ° to 337.5 °, the water outlet openings of the two sealing surfaces of the valve body are selectively in communication or out of communication with the first and second water inlet chambers 101 and 201, respectively, to switch different fluid flow paths between the first or second water inlets of the first or second housings and the respective water outlet pipes of the valve body.
The design is changed as shown in fig. 17, and a two-inlet and one-outlet selection valve 32' of the prior art is adopted to connect a single-inlet and multiple-outlet water diversion valve 32″ in series to replace the two-inlet and multiple-outlet water diversion valve 32 in the embodiment of the invention, so that the same cleaning function can be realized, but the pipeline structure is more complex.
The foregoing examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
