The sliding switch water outlet device as claimed in claim 2, wherein the tubular body is configured as an outer housing for conducting the first/second function water outlet path that is selectively movable toward/away from the water inlet nozzle to produce an upward/downward sliding displacement.

7. The sliding switching outlet device according to claim 6, wherein the sliding member comprises a sliding piece and a guiding assembly through hole located at the middle of the sliding piece, and the switching shaft is provided at the upper portion thereof with a protrusion adapted to the guiding assembly through hole.

8. The sliding switch water outlet device as claimed in claim 7, wherein the number of the guide fitting through-holes and the protrusions is 2, and at the side of each guide fitting through-hole, in the counterclockwise/clockwise direction:

the rotary assembly groove is used for supporting the lug to rotate in the groove; and

and the stopping part is arranged at the circumferential position between the rotating assembly groove and the other guiding assembly through hole and is used for stopping the lug from rotating for a certain angle in the rotating assembly groove so that the sliding part is in butt fit with the switching shaft.

9. The sliding switching water outlet device according to claim 7, wherein the inner wall surface of the tubular body is provided with at least two symmetrical protruding grooves for fitting with the sliding piece and driving the sliding piece when the tubular body generates upward/downward sliding displacement, the inner wall surface of the tubular body is further provided with at least two limiting grooves, the lower portion of the water inlet member is provided with at least two protrusions, and the limiting grooves are used for guiding and limiting with the protrusions.

10. A kitchen faucet comprising a sliding switch water outlet device according to any one of claims 1 to 9, a water inlet passage externally connecting the water inlet member, a faucet valve element, and a faucet switch for controlling the operation of the faucet valve element to realize water supply and water cut-off to the water inlet passage and the sliding switch water outlet device.
