When the limit button 36 is pressed, one end of the limit rod 362 can move in the second arc groove 312. When one end of the limit rod 362 moves in the second arc groove 312, the knob 35 drives the rotating shaft 34 to rotate so that another shielding member 342 can only shield another photoelectric switch 33. In this way, the photoelectric switch 33 can send another signal to the control board 30, so that the control board 30 can open the first electromagnetic switch valve 11a alone, so that boiling water can be output; when the output of boiling water reaches the required amount, release the knob 35, and the knob 35 is reversed back to its original position through the torque of the torsion spring 38. In this case, if the limit button 36 is not pressed, boiling water cannot be output, which improves the safety of use and prevents people from being scalded by boiling water.

When hot water mixed with cold and hot water is to be used, the handle 41 is turned to rotate the valve core of the water mixing valve 4, and the mixed hot water can be output for use in cleaning.

In this embodiment, boiled water, ice water and soda water are output from the first water outlet hole 91 of the water outlet, and the mixed hot water is output from the second water outlet hole 92, so that drinking water and cleaning water are output separately to prevent mutual contamination. In addition, the output of boiled water is safer through the cooperation of the limit button 36 and the torsion spring 38, which improves the safety of use. The control panel 30 can also control the light emission of LEDs of different luminous colors in the LED halo 316 through different signals given by the two photoelectric switches 33, so that the LED halo 316 can also emit different colors of light when the output state of boiled water, ice water or soda water is different, which improves the intuitiveness and convenience of use; the positioning column 39 installed on the knob 34 is matched with the different positioning concave holes 315 on the arc-shaped positioning protrusion 314 in turn, which can also facilitate people to control the rotation angle and orientation of the knob 35.

The above is only a preferred embodiment of the present invention. Any equivalent changes made by those skilled in the art according to the claims shall fall within the protection scope of this case.
