[0003] However, this technical solution still has deficiencies. In many areas, excessive intake of water with low hardness will cause the body to lack some trace elements. Therefore, at the working position of the water softener or the softening control valve, that is, while softening the water, a certain proportion of hard water can be appropriately mixed in to achieve the purpose of a moderate and balanced softness. However, the current mixing function of the control valve has the problem of unstable proportion of mixed hard water during long-term use. Summary of the Utility Model

In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0022] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. are usually based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description.

[0026] A self-locking type mixing valve structure of the present utility model, as Figures 1-5 shown, includes a valve body, end caps 1 and a base 7 provided at the upper and lower ends of the valve body, and a moving ceramic sheet 5 and a fixed ceramic sheet 6 provided inside the valve body. Through holes are provided on both the moving ceramic sheet 5 and the fixed ceramic sheet 6. Specifically, a water inlet communicating with the through hole on the fixed ceramic sheet 6 is provided on the base 7, and a flat washer 8 is also provided on the base 7. Water outlets are provided on both the left and right sides of the valve body, and both water outlets are connected to the through hole on the moving ceramic sheet 5.
[0027] A mixing water switch 2 is provided at the end cap 1. Specifically, the inside of the end cap 1 is hollow and sleeved outside the mixing water switch 2, and an indication mark corresponding to the state of the mixing water switch 2 is also provided on the end cap 1. The mixing water switch 2 is used to drive the rotation of the moving ceramic sheet 5. Specifically, the mixing water switch 2 is connected to the moving ceramic sheet 5 through a bracket 4. Through the rotation of the moving ceramic sheet 5, it is possible to realize the coincidence or non-coincidence of the through hole on the moving ceramic sheet 5 and the through hole on the fixed ceramic sheet 6 and the adjustment of the coincidence size. A self-locking component is also provided between the mixing water switch 2 and the end cap 1. The self-locking component includes a first gear ring provided on the outer periphery of the mixing water switch 2, a second gear ring provided inside the end cap 1 and meshing with the first gear ring, and a spring 3 provided between the mixing water switch 2 and the bracket 4. The spring 3 is used to press the first gear ring against the second gear ring for meshing.
[0028] The working principle of a self-locking type mixing valve structure of the present utility model is as follows:
[0029] When it is not necessary to mix raw water, press the mixing water switch 2 against the force of the spring 3 to disengage the first gear ring from the meshing limit of the second gear ring, and then rotate the mixing water switch 2 so that its arrow aligns with the "-" position on the end cap 1, as Figure 3 shown. At this time, the through hole on the moving ceramic sheet 5 and the through hole on the fixed ceramic sheet 6 are in a non-overlapping position. Release the mixing water switch 2, and under the action of the restoring force of the spring 3, the first gear ring and the second gear ring engage and are pressed tightly by the spring 3, that is, the mixing function is closed, as Figure 1 shown. The raw water enters from the upper water inlet, and because it is blocked, the raw water exits from the upper water inlet;
[0030] When it is necessary to mix in raw water, press the mixing water switch 2 against the force of the spring 3 to disengage the first gear ring from the meshing limit with the second gear ring, and then rotate the mixing water switch 2 so that its arrow aligns with the "+" position on the end cover 1 or the position between "+" and "-". At this time, the through holes on the moving porcelain piece 5 and the through holes on the fixed porcelain piece 6 are in a completely overlapping or partially overlapping state. As Figure 4 shown, the mixing water function is in a fully open, three-quarter open, half open or quarter open state, that is, the user controls the mixing ratio according to the size of the water outlet flow by the overlapping size of the through holes on the moving porcelain piece 5 and the through holes on the fixed porcelain piece 6. Release the mixing water switch 2, and under the action of the resilience of the spring 3, the first gear ring and the second gear ring are engaged and pressed by the spring 3, and then it can be stabilized at the required mixing water position. When the mixing water function is turned on, as Figure 2 shown, the raw water enters from the upper water inlet, and the raw water entering the valve body passes through the overlapping part of the through holes and exits from the water outlets on the left and right sides of the valve body.
[0031] In summary, a self-locking mixing valve structure provided by the present utility model has the advantages of simple structure, stable and reliable, convenient and effective, time-saving and labor-saving, has great market value, and is worthy of wide popularization and application.
[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
