Although the second recess 8 communicates with the first recess 5, the second recess 8 does not communicate with the first through hole 3 or the second through hole 4, so that in this case the water flow still only flows from the third through hole 7 to the third water outlet 17; when the movable valve plate 2 is located at the second rotation position, as shown in fig. 10, since the opening of the first groove 5 on the bonding surface is not intersected with the opening of the third through hole 7 on the bonding surface, the opening of the second groove 8 on the bonding surface is intersected with the opening of the first through hole 3 on the bonding surface and is not intersected with the opening of the second through hole 4 on the bonding surface, water flows through the first groove 5 and the second groove 8 after flowing from the water inlet 12 to the water inlet 6, and finally flows from the first through hole 3 to the first water outlet 13; when the movable valve plate 2 is at the third rotation position, as shown in fig. 11, the opening of the first groove 5 on the joint surface is not intersected with the opening of the third through hole 7 on the joint surface, the opening of the second groove 8 on the joint surface is intersected with the opening of the second through hole 4 on the joint surface and is not intersected with the opening of the first through hole 3 on the joint surface, so that water flows from the water inlet 12 to the water inlet 6, then flows through the first groove 5 and the second groove 8, and finally flows from the second through hole 4 to the second water outlet 14.

In this embodiment, since the bottom surface of the first groove 5 is provided with the water inlet 6, and the second groove 8 is always communicated with the first groove 5, when the valve plate 2 is rotated to be respectively located at the second rotation position or the third rotation position, the second groove 8 can be respectively communicated with the first through hole 3 and the second through hole 4, so that the two water outlets at the bottom can be switched; and when the movable valve plate 2 is positioned at the first transmission position, the first groove 5 can be communicated with the third through hole 7, and the second groove 8 is not communicated with any through hole, so that top water outlet is realized. Meanwhile, as the water inlet hole 6 is formed in the bottom surface of the first groove 5, water inlet at the side end is avoided, and the external waterway is convenient to butt joint, so that the complexity of the waterway structure is reduced, and the cost is reduced.

In this embodiment, since the movable valve plate 2 and the fixed valve plate 1 are generally made of ceramic, and for sealing, the bonding surfaces of the movable valve plate 2 and the fixed valve plate 1 need to be polished very smooth, so that a photoresist phenomenon can be generated, and further the movable valve plate 2 is prevented from rotating relative to the fixed valve plate 1. According to the embodiment, the third groove 9 is formed in the fixed valve plate 1 and the opening of the third groove faces the movable valve plate 2, so that the contact area between the movable valve plate 2 and the fixed valve plate 1 is reduced, and the obstruction of the photo-adhesive phenomenon to the rotation of the fixed valve plate 1 is further reduced.
