The pointer 11 is installed to the valve knob 1 lower extreme, and the sharp one side of pointer 11 is the instruction limit, and the pilot wheel 2 is provided with first indicator 21 in the front, is provided with second indicator 22 in the reverse. The direction of the pointer 11 is matched with the first indicator 21 when the water mixing valve is used in the forward direction and matched with the second indicator 22 when the water mixing valve is used in the reverse direction according to the actual use requirement.
The valve core rod 31 of the valve core 3 is provided with an inclined surface at the top end, the inner center of the valve knob 1 is provided with a valve core hole matched with the valve core rod 31, the bottom end of the valve core hole is provided with an inclined surface bulge matched with the inclined surface, so that the valve core rod 31 and the valve knob 1 are mutually limited and fixed and do not generate relative displacement, and the valve knob 1 drives the valve core 3 to rotate in the inner cavity of the valve body 5 by a corresponding angle when rotating, thereby realizing flow control of water inlet and outlet.
Further, as shown in fig. six, the lower end of the valve core 3 is composed of a blocking surface 32 and an arc opening 33, and the arc opening 33 forms an arc structure protruding toward the blocking surface 32 at the junction with the blocking surface 32. Because the water inlet and the water outlet are all circular, the traditional straight opening can cause uneven change of flow when water flows through, thereby affecting temperature control. The arc opening 33 can enable the water inlet and outlet flow rate of the first water inlet 51, the second water inlet 52 and the mixed water outlet 53 to tend to linearly change when the valve core 3 rotates, and is more convenient for the mixed water valve to regulate temperature.

The sealing columns 41 at the upper end and the lower end are respectively provided with a compensation knob 411, the direction of a groove on the compensation knob 411 is consistent with that of the blocking piece 42, and the opening and closing state of the blocking piece 42 can be realized by rotating the compensation knob 411.
