The two extreme positions, i.e. the docking outlet 33 is rotated to a first extreme position in which it docks with the second tapping outlet 23 and to a second extreme position in which it docks with the third tapping outlet 24.

Specifically, the first limiting portion 26 is a limiting block, the second limiting portion 34 is an arc-shaped strip, and when the rotating member 30 rotates to the limiting position, the end portion of the arc-shaped strip abuts against the limiting block. That is to say, when rotating to extreme position, the tip of arc strip can end on the stopper, can carry out the spacing cooperation of circumference like this. Of course, the present invention is also not limited to this, the second limiting portion 34 can also be set to two circumferentially spaced limiting blocks, and the central angle corresponding to the two limiting blocks is the same as the central angle corresponding to the first water diversion outlet 22 and the second water diversion outlet 23. The first limiting part 26 and the second limiting part 34 are simple in structure and good in limiting effect, reliability of the water diversion device 90 can be further guaranteed, and accuracy of user operation after switching can be guaranteed.
