Referring to FIG. 9 to FIG. 14 , when the button 800 is pressed, the button 800 drives the C-type retaining spring 600 to slide, and the end of the first flying rod 621 or the barb top abuts against the first inclined surface 1411 , so that the flying rod rotates to one side, and Moving downward along the first inclined surface 1411. During this process, the button 800 drives the button holder 500, the spool shaft 200, and the sealing unit 300 to move downward. When the sealing unit 300 contacts the port of a water dividing hole 120, the sealing unit 300 stops moving, the inner elastic body 400 is compressed, and the spool shaft 200 continues to move downward. When the limit point is exceeded, the button 800 is released, the C-type retaining spring 600 is reset, and the outer elastic body 700 is released, and the upward movement causes the barb of the first flying rod 621 to be hooked to the first groove.

Referring to FIG. 15 to FIG. 20, when the button 800 is pressed again, the barb of the first suspended rod 621 is disengaged from the first groove. The C-shaped snap spring 600 rotates toward the other side such that the end of the second flying rod 6 or the barb top abutment 22 tilts the seat 142 and moves downward along the second inclined surface of the tilting seat 142. During this process, the button 800 drives the button base 500 and the spool shaft 200 to move downward, the inner elastic body 400 is compressed, and the sealing unit 300 continues to close the water dividing hole when the second flying rod 6 ends or the barb is separated from the second. After the inclined surface, the C-shaped retaining spring 600 is reset to the guiding surface 1412, and the button 800 is released. Under the driving of the outer elastic body 700, the C-shaped retaining spring returns to the free state along the guide rail. The inner elastic body 400 drives the button, the button seat and the valve core to move axially, and the elastic force of the inner elastic body is released. When the step 240 of the valve core shaft contacts the sealing unit, the valve core shaft drives the sealing unit to open the original water dividing hole, and seals another Divide the water hole to complete the switch.

According to the need, the water function can be set as a shower on the two-way waterway.

The above is only the preferred embodiment of the present invention, and thus the scope of the present invention is not limited thereto, that is, equivalent changes and modifications made in accordance with the scope of the invention and the contents of the specification should still be covered by the present invention. Within the scope.
