In order to realize the above functions, at least two or three valve cores need to be installed on the faucet, resulting in a large structure and volume of the faucet. Therefore, more and more integrated valve cores appear. For example, a multifunctional control valve and a shower disclosed in Chinese patent CN114060568B realizes the switching, flow rate adjustment, and temperature adjustment of water flow by rotating and pulling the handle bar, and realizes the switching of the water path by pressing the button. Although the above-mentioned structure integrates the functions of switching, flow rate adjustment, water temperature adjustment, and water path switching, at least two types of handles need to be provided, the internal structure is complex, and the valve core is large in size. When used by the user, the user needs to move to the button to operate the two handles when opening the water flow, adjusting the temperature, and switching the water path, which is not conducive to the use of the user. At the same time, the gear position is difficult to judge by pressing the button. In addition, the provision of the two handles also greatly limits the appearance of the faucet body. SUMMARY

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0039] Combination Figures 1 to 19 This embodiment provides a dual-outlet water control valve, including a valve body 1, a stationary plate 2, a moving plate 3, and a valve stem 4. Specifically, the valve body 1 is provided with a cold water inlet 11, a hot water inlet 12, a first water outlet 13, and a second water outlet 14. The stationary plate 2 is installed inside the valve body 1 and is provided with water passages that correspond one-to-one with each water inlet and water outlet. The moving plate 3 is fitted to the stationary plate 2 and is provided with a first mixing chamber 31 for communicating with the first water outlet 13 and a second mixing chamber 32 for communicating with the second water outlet 14. The valve stem 4 is sleeved on the valve body 1 and can swing and rotate relative to the valve body 1. The moving plate 3 and the valve stem 4 are linked. By driving the valve stem 4 to swing, the moving plate 3 is moved, thereby selecting one mixing chamber to communicate with the water inlet. By driving the valve stem 4 to rotate, the moving plate 3 can be rotated synchronously to adjust the overlapping area of ​​the two water inlets and the mixing chamber.

[0040] For example, refer to Figure 3 , Figure 4 and Figure 9 When in the closed position, both mixing chambers on the moving plate 3 are misaligned with the inlet hole, as shown in the reference. Figure 5 , Figure 6 and Figure 10 When the moving plate 3 moves from the closed position in the first direction, the first mixing chamber 31 connects with the inlet hole, and water flows out of the first outlet hole 13. The movement distance of the moving plate 3 can be controlled by adjusting the swing angle of the valve stem 4, thereby controlling the overlap area between the mixing chamber and the two inlet holes, and thus adjusting the water flow rate. Simultaneously, by driving the moving plate 3 to rotate, the overlap area between the cold water inlet hole 11 and the hot water inlet hole 12 and the mixing chamber can be adjusted, thereby adjusting the ratio of cold and hot water intake and regulating the outlet water temperature. (Refer to...) Figure 7 , Figure 8 and Figure 11When the moving piece 3 moves from the closed position to the second direction opposite to the first direction, the second water mixing cavity 32 is communicated with the water inlet hole, and the overlapping area of the water mixing cavity with the two water inlet holes can be controlled by controlling the moving distance, so as to adjust the water outlet flow rate, and the moving piece 3 is driven to rotate, so as to adjust the water temperature.

[0041] It should be noted that in the embodiment, only one handle is needed to realize the switching, flow rate adjustment, temperature adjustment and water path switching, so as to facilitate the user operation. When the water path is switched, the valve rod 4 drives the moving piece 3 to move in different directions, and the valve rod 4 swings in different directions correspondingly, and the swing angle is obvious, so that the user can judge the gear state. For example, when the valve rod 4 is in the vertical position, the moving piece 3 swings to the left when it moves in the first direction, and swings to the right when it moves in the second direction, so that each position is clear and distinct, and the user can prevent misoperation. The user can directly swing the valve rod 4 to the direction of the required gear before the water flow is opened, so as to directly open the water flow of the required gear, which is convenient and fast.

Further, the first water mixing cavity 31 is arranged in the middle part of the bottom surface of the moving piece 3, and the water inlet flow channel 321 and the water outlet flow channel 322 are arranged on both sides of the first water mixing cavity 31. While ensuring the water inlet and outlet cross sections of the first water mixing cavity 31 and the second water mixing cavity 32, the structure on the moving piece 3 is more compact, the volume of the moving piece 3 is reduced, and the overall volume of the valve core is further reduced, so as to avoid the influence of the large valve core structure on the appearance design of the faucet.
