Specifically, the bottom cover 20 is a stepped column structure with a smaller diameter at the top and a larger diameter at the bottom, including a small diameter portion 27 located inside the lower port of the valve housing 10 and a large diameter portion 28 located outside the lower port of the valve housing 10. The small diameter portion 27 of the bottom cover 20 corresponds to its... The upper surface has several buckles 271 spaced around its outer periphery, and the valve housing 10 has corresponding slots 14 that cooperate with the buckles 271. The buckles 271 and slots 14 cooperate to securely install the bottom cover 20 on the valve housing 10.

[0037] like Figure 4 , Figure 6 , Figure 7 and Figure 11 As shown, the ceramic plate 50 is positioned on the small-diameter portion 27 of the bottom cover 20. A first water passage hole 51 is provided in the middle of the ceramic plate, and a first water inlet hole 52, a second water inlet hole 53, a third water inlet hole 54, a fourth water inlet hole 55, and a fifth water inlet hole 56 are evenly spaced around the outer periphery of the first water passage hole 51. A second water passage hole 21 is provided on the bottom cover 20 corresponding to the first water passage hole 51 to form a first water passage channel. A first mating hole 22, a second mating hole 23, a third mating hole 24, and a fourth mating hole 25 are provided on the bottom cover 20 corresponding to the first, second, third, and fourth water inlet holes 55 to form the first, second, third, and fourth water inlet channels, respectively.

In this embodiment, the elongated ceramic moving plate 40 is provided with a slot 42 at both ends. The linkage part 31 of the rotating shaft 30 is provided with a corresponding claw 311 for engaging in the slot 42. Thus, the linkage between the rotating shaft 30 and the ceramic moving plate 40 can be achieved by the engagement of the slots 42.

This facilitates the external power component to drive the rotating shaft 30 to rotate the ceramic moving plate 40 on the ceramic fixed plate 50, thereby controlling the valve core to switch between the water production state and the flushing state.

[0040] Compared with existing technologies, this utility model has a simple and reasonable structure. By rotating the shaft, the ceramic moving plate can be driven to rotate on the ceramic fixed plate, which can easily control the valve core to switch between water production and flushing states. When the ceramic moving plate is covering the first water passage and the fifth water inlet, external water flows into the valve core through the first, second, third, and fourth water inlets. At this time, the first water passage and the fifth water inlet, which are connected by the connecting groove on the ceramic moving plate, are in a closed state, and no wastewater is discharged. The valve core is in the water production state. When the ceramic moving plate is covering the first water passage and the first water inlet, external water enters the valve core through the second, third, and fourth water inlets. At this time, the first water passage and the first water inlet, which are connected by the connecting groove on the ceramic moving plate, are in a connected state. Wastewater is discharged through the channel formed by the first water passage and the second water passage. The valve core is in the flushing state. At the same time, the valve core of this utility model can realize various product water circuits by cooperating with different valve body shells, such as one flush with one valve head or three flushes with one valve head, which greatly saves development costs.

[0041] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
