referring to fig. 5, at this time, the rotating member 33 is engaged with the first positioning groove (not shown) on the sleeve 31, so that the pushing member 32 retracts relative to the sleeve 31, the pushing member 32 further drives the first water outlet nozzle to a retracted position through the valve core 60, and the first water outlet 41 retracts into the housing 12 to be hidden, so that the sanitation of the first water outlet 41 is better. At this time, the valve core 10 is at the second position to close the first valve port 112 and open the second valve port 113, such that the first water inlet channel 111a is disconnected from the first water outlet 41, the second water inlet channel 111b is communicated with the second water outlet 51, and the water flow of the second water inlet channel 111b flows out downwards from the second water outlet 51.
Referring to fig. 4, in the state of fig. 5, the first water nozzle is pressed once, the first water nozzle drives the pushing member 32 to axially slide toward the left direction in the drawing through the valve core 60, the pushing member 32 further drives the rotating member 33 to axially slide toward the left direction in the drawing, when the rotating member 33 slides to lose the circumferential limit with the inner wall of the sleeve 31, under the action of the first ratchet 321 and the second ratchet 331, the rotating member 33 rotates by a predetermined angle to be engaged with the second positioning slot (not shown) on the sleeve 31, so that the pushing member 32 extends relative to the sleeve 31, the pushing member 32 further drives the first water nozzle to move from the retracted position of fig. 5 to the extended position of fig. 4 through the valve core 60, and the first water outlet 41 is exposed out of the housing 12. Meanwhile, the valve core 60 moves from the second position to the first position to open the first valve port 112 and close the second valve port 113, so that the first water inlet channel 111a communicates with the first water outlet 41, the second water inlet channel 111b is cut off from the second water outlet 51, and the water in the first water inlet channel 111a flows out from the first water outlet 41.
While the foregoing specification illustrates and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the precise forms disclosed herein and is not to be interpreted as excluding the existence of additional embodiments that are also intended to be encompassed by the present invention as modified within the spirit and scope of the invention as described herein. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
