When the position of the switching shaft 31 extending out of the housing 10 is pressed, the switching shaft 31 drives the reset shaft 32 to move axially inward against the elastic force of the reset elastic member 33, after the switching seat 20 rotates by a first angle under the cooperation of the second switching inclined surface of the reset shaft 32 and the third switching inclined surface 2511 of the switching sleeve 25, the third protrusion 321 of the reset shaft 32 slides into the second sliding groove 252 of the switching sleeve, and since the switching seat 20 rotates by the first angle, at this time, the first switching inclined surface 3111 of the switching shaft 31 corresponds to the fourth switching inclined surface 253 of the switching sleeve 25, the switching shaft 31 is continuously pressed, and after the switching seat 20 rotates by a predetermined angle, under the cooperation of the first switching inclined surface 3111 of the switching shaft 31 and the fourth switching inclined surface 253 of the switching sleeve 25, the switching seat 20 continues to rotate by a second angle in the same direction, the first angle plus the second angle is a predetermined angle for each rotation of the switching seat 20, the water outlet is switched from one water outlet 15 to another water outlet 15.
When the driving force applied to the switching shaft 31 is removed, the switching shaft 31 and the reset shaft 32 are reset under the action of the reset elastic member 33, so that the second protrusion 311 of the switching shaft 31 slides into the first sliding slot 1212, the third protrusion 321 of the reset shaft 32 slides out of the second sliding slot 252, and the second reset inclined surface 3211 of the reset shaft 32 is in abutting fit with the first reset inclined surface 12111 of the shaft sleeve 121, so that the reset shaft 32 is rotationally reset to a position where the second switching inclined surface 3212 of the reset shaft 32 corresponds to the third switching inclined surface 2511 of the switching sleeve 25, i.e., to the initial non-pressed position shown in fig. 2, and is ready for the next switching;
in this embodiment, after the third switching shaft 31 is pressed, the positions of the first through-flow hole 21 and the second through-flow hole 22 are switched, that is, the first through-flow hole 21 corresponds to the water inlet 14 as the water inlet of the switching seat 20 and the second through-flow hole 22 corresponds to the water outlet 15 as the water outlet of the switching seat 20 in the initial state, then, after the third switching shaft 31 is pressed, the second through-flow hole 22 corresponds to the water inlet 14 as the water inlet of the switching seat 20 and the first through-flow hole 21 corresponds to the water outlet 15 as the water outlet of the switching seat 20.
