The second elastic member 43 is pushed against the push block 44 against the temperature control rod 31. More specifically, the control shaft 41 passes through the upper cover 11 for the user to control (can be equipped with a handle), and the first elastic member 33 and the second elastic member 43 are used for the temperature control rod. Both the push block 44 and the push block 44 are held against each other at any time, so that the temperature control rod 31 and the shutter 32 are held in a fixed position.

In addition, in order to increase the adhesion between the temperature control shaft body and the base, the two ceramic sheets 50 disposed in the base 20 may be further included. The two ceramic sheets 50 include a movable piece 51 and a fixing piece 52. The movable piece In conjunction with the bottom end of the inner body 13, the fixing piece 52 is interlocked with the base 20, and each of the ceramic sheets 50 is formed with a plurality of perforations to correspond to the water outlet 21, the hot water inlet 22 and the cold water inlet 23.

In addition, in order to facilitate assembly, the inner wall of the outer body 12 has a downward facing step surface 121 near the top end of the outer body 12. The inner body 13 is inserted into the outer body 12 from the lower end of the outer body 12 to be abutted. To the step surface 121.

Preferably, for the convenience of assembly, the base 20 covers the lower half of the outer body 12, and an outer cover 60 is interposed between the outer body 12 and the base 20 and The base 20 is fixed to each other.

In actual use, hot water and cold water respectively enter from the hot water inlet 22 and the cold water inlet 23, and the hot water sequentially passes through the first flow passage 101 and the first water inlet hole 131 to enter the chamber, and the cold water is sequentially followed. After the second flow passage 102 and the second water inlet hole 132 enter the chamber, the cold water and the hot water are mixed in the chamber, and finally discharged to the outside through the water outlet hole 21.

Moreover, the user can rotate the outer body 12 (via a handlebar, etc.) to make the water inlet and the flow path offset from each other to close the water source, thereby controlling the opening and closing of the water and the flow rate. In addition, the user can push the control knob 41 to push the temperature control rod 31 to change the blocking position of the shielding member 32, thereby adjusting the ratio of cold and hot water flow to achieve the effect of adjusting the water temperature.

Since the temperature control rod 31 is elongated by thermal expansion and becomes cold and contracted, when the temperature of the mixed water in the chamber is too high, the temperature control rod 31 is extended, and the shielding member 32 is moved downward to cover the first More of the water inlet hole 131, and more away from the second water inlet hole 132, so that the amount of hot water inflow increases and the amount of cold water inflow decreases, the effect of balancing the water temperature can be achieved, and vice versa.

Therefore, the composite water control shaft provided by the present invention has a simple structure, is easy to assemble and manufacture, and can achieve the functions of controlling the water, water volume and water temperature of the switch, and has the function of automatically balancing the water temperature, which is highly effective. .
