The water-mixing valve core in this embodiment is embodied as a thermostatic valve core 6. 'therefore, the water-mixing valve may also be defined as the thermostatic valve 100. The thermostatic valve core 6 is a conventional technology, as described in the patent documents EP0936524A, ES6085984, ES20090314844A1, US20180364745A1, EP1235129A1, etc., which is not described herein.

The first water inlet 51 and the second water inlet 52 are respectively configured to be externally connected to water sources with different water temperatures, and are respectively arranged at radial positions of outer cavity walls of the two waterway switching cavities 54. 'the water-mixing valve core cavity 50 is configured to have a thermostatic valve core 6 disposed therein, and two first water-passing openings 5421 and two second water-passing openings 5422 are respectively provided in cavity -wall sections commonly used by the water-mixing valve core cavity 50 and the Iwo waterway switching cavities 54 in the axial direction, and each of the first water-passing openings 5421 is in fluid communication with a cold water inlet 61 of the thermostatic valve core 6, and each of the second water passages 5422 is in fluid communication with a hot water inlet 62 of the thermostatic valve core 6, and the water-mixing valve core cavity 50 is provided with at least one mixed water outlet 53, and the mixed water outlet 53 is configured to be in fluid communication with a water outlet 63 of the thermostatic valve core 6. The bottom of each of the waterway switching cavities 54 is provided with a water inlet channel 541, and the water inlet channels 541 of the two watenvay switching cavities 54 are respectively in communication with corresponding first water inlet 51 or second water inlet 52. Moreover, insertion ends of the two waterway switching cavities 54 are each provided with internal screw threads 542, and the housing 1 of the waterway switching valve core 10 is provided with external screw threads 15 at a position corresponding to the internal screw threads 542. The waterway switching valve core 10 is inserted into the waterway switching cavity 54 and is fixed by the threaded connection, so that the waterway switching valve core 10 is fixedly arranged inside the watenvay switching cavity 54, and also the upper water outlet 12 and the lower water outlet 13 of each of the watenvay switching valve core 10 arc respectively connected to the first water-passing opening 5421 and the second water-passing opening 5422 of the corresponding waterway switching cavity 54. The barrier wall 33 at the outer side of the movable sleeve 3 can be switched between the upper water outlet 12 and the lower water outlet 13 of the housing 1 as required, the water inlet 37 of each of the waterway switching valve cores 10 is in fluid communication with the water inlet channel 541 of the corresponding waterway switching cavity 54.
[0024] The user can adjust the upper and lower positions of the movable sleeve 3 in the housing 1 as required, so as to select the outer barrier wall 33 of the movable sleeve 3 to be located outside the upper water outlet 12 or the lower water outlet 13. Alien the outer barrier wall 33 of the movable sleeve 3 is located outside the upper water outlet 12, the water outflowing from the upper water outlet 12 is blocked, and the lower water outlet 13 is opened, then the water flow in the movable sleeve 3 flows out from the lower water outlet 13. On the contrary, when the outer barrier wall 33 of the movable sleeve 3 is located at the lower water outlet 13, the water outflowing from the lower water outlet 13 is blocked, and the upper water outlet 12 is opened, and the water flow in the movable sleeve 3 flows out from the upper water outlet 12.

The arrangement that the above water sources with different water temperatures flowing into the first water inlet 51 and the second water inlet 52 is defined as a forward watenvay arrangement; in this embodiment, the cold water inlet 61 of the thermostatic valve core 6 is located at an upper side to be in fluid communication with the upper water outlets 12 of the waterway switching valve cores 10 on the two sides, and the hot water inlet end 62 of the thermostatic valve core 6 is located at a lower side to be in fluid communication with the lower water outlets 13 of the watenvay switching valve cores 10 on the two sides. [0026] Tn this case, the movable sleeve 3 of the waterway switching valve core 10 in the left waterway switching cavity 54 is adjusted upwards, to allow the outer barrier wall 33 to be located at the upper water outlet 12, and since the outer barrier wall 33 is provided with sealing rings 32 at an upper position and a lower position, the two sealing rings 32 are closely matched with the housing 1, which effectively blocks the water flow from flowing out through the upper water outlet 12, and the hot water flows out from the lower water outlet 13 of the left waterway nvitching valve core 10, thereby entering the hot water inlet 62 of the thermostatic valve core 6 through the water outlet channel 5422 't he movable sleeve 3 of the waterway switching valve core 10 in the right watenvay switching cavity 54 is adjusted downward, so that the outer barrier wall 33 is located at the lower water outlet 13, and the two sealing nngs 32 block the water flow from flowing out through the lower water outlet 13. The cold water flows out from the upper water outlet 12 of the right waterway switching valve core 10, and then enters the cold water inlet 61 of the thermostatic valve core 6 through the water outlet channel 5421; after the cold water and hot water are mixed in the thermostatic valve core 6, the mixed water flows out via the water outlet 63 of dic thermostatic valve core 6 to the mixed water outlet 53 of the main body of the valve scat 5.
[0027] Tf the situation shown in Figure 7 is encountered, that is, the left side is the second water inlet 52, but the left side corresponds to the cold water source; the right side is the first water inlet 51, but the right side corresponds to the hot water source, contrary to the previous situation, the arrangement that the above water sources with different water temperatures flowing into the first water inlet 51 and the second water inlet 52 is defined as a reverse waterway arrangement. When this happens, it is generally because the pre-embedded tubes for connecting the cold water source and hot water source are arranged incorrectly, and if the movable sleeves 3 of the waterway switching valve cores 10 in the two watenvay switching cavities 54 are arranged in the manner described above, it may cause abnormal water How in the thermostatic valve core 6, that is, the hot water will enter the cold water inlet 61 of the thermostatic valve core 6 and cold water will enter the hot water inlet 62 of the thermostatic valve core 6.
[0028] In this case, just as shown in Figure 6 and Figure 7, the hexagonal wrench 7 is used to be inserted into the counterbore 24 of the adjustment rod 2, and the adjustment rod 2 is turned with the hexagonal wrench 7 to adjust the direction of the movable sleeve 3 in each of the waterway switching valve cores.
[0029] The movable sleeve 3 of the waterway switching valve core 10 n the left waterway switching cavity 54 is adjusted downwards, to allow the outer barrier wall 33 to be located at the lower water outlet 13, which effectively blocks the water flow from flowing out through the lower water outlet 13, and the cold water on the left flows out from the upper water outlet 12 of the left waterway switching valve core 10, thereby entering the cold water inlet 61 of the thermostatic valve core 6. The movable sleeve 3 of the waterway switching valve core 10 in the right waterway switching cavity 54 is adjusted upward, so that the outer barrier wall 33 is located at the upper water outlet 12, which blocks the water flow from flowing out through the upper water outlet 12, and the hot water flows out from the lower water outlet 13 of the right waterway switching valve core 10, and then enters the hot water inlet 62 of the thermostatic valve core 6. After the cold water and hot water are mixed in the thermostatic valve core 6, the mixed water flows out via the water outlet 63 of the thermostatic valve core 6 to the mixed water outlet 53 of the main body of the valve scat 5. As shown in Figure 7, the mixed water outlet 53 is provided with a switch valve core 8, and the switch valve core 8 is used to control water outflowing.
