Please refer to Figures 9 to 14, press the button 800, the button 800 will drive the C-shaped circlip 600 to slide, and the end of the suspension rod or the barb will abut against the first inclined surface 1411, so that the suspension rod rotates to one side and moves along the first inclined surface 1411. An inclined surface 1411 moves downward. During this process, the button 800 drives the button seat 500 , the valve core shaft 200 and the sealing unit 300 to move downward. When the sealing unit 300 touches the port of a water diversion hole 120, the sealing unit 300 stops moving, the inner elastic body 400 is compressed, and the valve core shaft 200 continues to move downward. When the limit point is exceeded, the button 800 is released, the C-shaped circlip 600 resets, and the outer elastic body 700 releases its energy and moves upward so that the barb hooks into the first groove. The elastic force of the inner elastic body 400 is released, so that the sealing unit always closes the port of the water diversion hole to complete the switching of the water channel.

Please refer to FIG. 15 to FIG. 20 , when the button 800 is pressed, the button 800 drives the C-shaped snap ring 600 to rotate to the other side and move downward along the second inclined surface of the inclined seat 142 . During this process, the button 800 drives the button seat 500 and the valve core shaft 200 to move downward, the inner elastic body 400 is compressed, and the sealing unit 300 continues to close the water diversion hole. When the C-shaped circlip 600 is separated from the second inclined surface, the C The type circlip 600 returns to the guide surface 1412, the button 800 is released, and driven by the outer elastic body 700, the C-type circlip returns to a free state along the guide rail. The inner elastic body 400 drives the button, the button seat, and the spool shaft to move upward, and the elastic force of the inner elastic body is released. When the step 240 of the spool shaft contacts the sealing unit, the spool shaft drives the sealing unit to open the original water diversion hole and seal the other A split water hole, thus completing the switch.

According to the needs, the water outlet function part can be set as a shower in the two-divided waterway.

The above is only a preferred embodiment of the present invention, so the scope of the present invention cannot be limited accordingly, that is, the equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still be covered by the present invention within range.
