[0069] The moving plate 110 follows the sliding plate 800 and moves linearly relative to the static plate 120 under the pitching and tilting of the valve stem 200, forming four states. Figures 18 to 21 As shown, in the first state, the first water hole 1101 is connected to the cold water inlet hole 1203, the hot water inlet hole 1204 and the first water mixing hole 1201, and water flows out of the first water mixing hole 1201, that is, water flows out of the first water mixing outlet 1403; Figure 22 to Figure 25 As shown, the second state is that the second water hole 1102 is connected to the second water mixing hole 1202, and the first water hole 1101 is connected to the cold water inlet hole 1203 and the hot water inlet hole 1204, and the second water mixing hole 1202 discharges water, that is, the second water mixing outlet 1404 discharges water; Figure 26 to Figure 29 As shown, the third state is that the moving piece 110 partially covers the cold water inlet hole 1203 and the hot water inlet hole 1204, and the third mixed water outlet 103 discharges water; Figure 30 to Figure 31As shown, in the fourth state, the movable plate 110 blocks the cold water inlet hole 1203 and the hot water inlet hole 1204, and at the same time, the first water hole 1101 and the second water hole 1102 are staggered with the cold water inlet hole 1203 and the hot water inlet hole 1204 to close the water path. The movable plate 110 follows the sliding plate 800 and rotates relative to the static plate 120 under the rotation of the valve stem 200 to adjust the water flow area of ​​the cold water inlet hole 1203 and the hot water inlet hole 1204, thereby adjusting the water temperature of the mixed water.

[0070] The working process is as follows:

[0071] Initially, the valve core is in a closed waterway state. At this time, the free end 5022 is stuck in the corresponding closed state slot 8011. The valve stem 200 is pushed to the left to push the movable plate 110 to slide to the right. When the positioning bar 502 makes a sound, the free end 5022 is stuck in the corresponding first state slot 8011. The first water hole 1101 connects the cold water inlet hole 1203, the hot water inlet hole 1204 and the first mixing water hole 1201. Water flows out of the first mixing water hole 1201, which is the first mixing water. Water flows out of the outlet 1403; continue to push the valve stem 200 to the left, push the movable plate 110 to continue to slide to the right, when the sound of the positioning strip 502 is heard again, the free end 5022 is now inserted into the corresponding second state of the notch 8011, the second water hole 1102 is connected with the second mixing water hole 1202, and at the same time, the first water hole 1101 is connected with the cold water inlet hole 1203 and the hot water inlet hole 1204, and water flows out of the second mixing water hole 1202, that is, water flows out of the second mixing water outlet 1404.

[0072] At this time, the valve stem 200 is pushed rightward twice continuously to push the movable plate 110 to slide leftward. When the positioning bar 502 makes a second sound, the free end 5022 is reset to the notch 8011 corresponding to the closed state, and the water channel is closed.

[0073] The valve stem 200 is continuously pushed to the right, pushing the movable piece 110 to slide to the left, and when the positioning strip 502 makes a sound again, the free end 5022 is inserted into the corresponding notch 8011 of the third state, and the movable piece 110 partially covers the cold water inlet hole 1203 and the hot water inlet hole 1204, and water flows out of the third mixed water outlet 103 and the fourth mixed water outlet 1408. In actual use, the user can select the third mixed water outlet 103 or the fourth mixed water outlet 1408 to flow out water according to the installation position of the faucet.

[0074] At this time, the valve stem 200 is pushed to the left, pushing the movable plate 110 to slide to the right, and the water channel is closed.

[0075] The valve stem 200 is rotated in the first, second and third states of the valve core to drive the movable plate 110 to rotate together, thereby controlling the water inlet ratio of cold and hot water and adjusting the water outlet temperature.

[0076] In other embodiments, reference Fig.32 As shown, the valve stem 200 is provided with a limiting protrusion 203 for limiting the sliding of the movable plate 110 toward the second mixed water outlet 1404, that is, the second mixed water outlet 1404 cannot discharge water, and only the two mixed water outlets are switched, and the valve core is changed to a dual-function valve core.

[0077] The present embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
