The water inlet end of the cold water through hole 311 is circular, and the water inlet end of the hot water through hole 312 is comma-shaped with the opening gradually increasing or decreasing in size along the rotation direction of the opening control plate 32.
The outlet ends of the cold water through hole 311 and the hot water through hole 312 extend out of the casing 1 along the cold water outlet 12 and the hot water outlet 13 through the cold water pipe 33 and the hot water pipe 34, respectively.
The rotating shaft 35 comprises a first shaft body 351 and a second shaft body 352, corresponding seat body through holes 313 and sheet body through holes are respectively formed in the flow control seat 31 and the opening control sheet 32, one end of the second shaft body 352 extends into the seat body through holes 313 and is provided with a plug 3521, one end of the first shaft body 351 extends into the seat body through holes 313 after passing through the sheet body through holes and is connected with the plug 3521 in an inserting mode through an inserting port, and the first shaft body 351 is fixed with the opening control sheet 32.

The working process of the invention comprises the following steps:
referring to fig. 8, when the water diversion trench 321 is opposite to the cold water through hole 311, tap water can enter the water inlet pipeline through the water inlet 11 and then leave through the cold water conduit 33 after passing through the water diversion trench 321 and the cold water through hole 311 in sequence.
When the stepping motor 2 drives the rotation shaft 35 to rotate clockwise until the water diversion through-groove 321 is opposite to the side where the mouth of the hot water through-hole 312 is relatively large (as shown in fig. 9), tap water can enter the water inlet pipe through the water inlet 11 and then leave through the hot water guide pipe 34 after passing through the water diversion through-groove 321 and the hot water through-hole 312 in sequence. At this time, the flow rate of the hot water pipe is at a maximum state.
As the stepping motor 2 continues to drive the rotation shaft 35 to rotate clockwise, the mouth of the hot water through hole 312 aligned with the water diversion through groove 321 gradually decreases, so that the flow rate of the hot water pipeline gradually decreases. When the water diversion through-groove 321 is opposite to the side where the mouth of the hot water through-hole 312 is relatively small, the flow rate of the hot water pipe is in a minimum state.
When the stepper motor 2 drives the rotating shaft 35 to rotate so that the water diversion through groove 321 is not aligned with the cold water through hole 311 nor the hot water through hole 312, the lamination switching flow regulating device 3 is in a closed state.
In addition, in the process of driving the rotating shaft 35 to rotate by the stepping motor 2, the driving component 4 can also be utilized to drive the piston rod 51 to synchronously rotate. When the water diversion through-groove 321 is aligned with the cold water through-hole 311 or the hot water through-hole 312 (i.e., when the cold water pipe or the hot water pipe is opened), the water inlet pipe is also in an open state because a gap exists between the piston cap 53 and the tight cap 14. Referring to fig. 3 and 4, when the water diversion through-groove 321 is not aligned with the cold water through-hole 311 or the hot water through-hole 312 (i.e. when both the cold water pipe and the hot water pipe are closed), the opening device 5 moves along the length direction of the piston rod 51 under the interaction of the protrusion 15 and the arc-shaped groove 521 until the piston cap 53 abuts against the cap seat 14 and closes the water inlet pipe.
Embodiment two:
the opening device 5 controls the opening and closing of the water inlet valve device 7 by the coil 8.
Other embodiments are the same as the first embodiment.
Compared with the first embodiment, the embodiment is quite similar to the first embodiment in that two power sources (the stepping motor 2 and the coil) are adopted to respectively control the operation of the lamination switching flow regulating device 3 and the opening device 5, the structure is simpler, and only the cost is increased to a certain extent.
The above embodiments are illustrative of the present invention, and not limiting, and any simple modifications of the present invention fall within the scope of the present invention.
