The waterway switching device is arranged in a water tank of a closestool, water in the water tank is connected with two pipelines for different purposes, and the waterway switching device realizes automatic switching of two waterways. In the device body 10, the water inlet 111 is used for communicating with an external water source, and the external water source enters the device body 10 through the water inlet 111 and then enters the switching cavity 12. In this embodiment, the external water source is the water stored in the toilet tank pumped into the device body 10 by the water pump 30.

The switching cavity 12 is internally provided with a first water outlet 13 and a second water outlet 14, and the two water outlets are used by conveying water to different places through a water conveying pipeline, in the embodiment: the first water outlet 13 is connected to the brush ring line of the toilet bowl (only a small section is shown in the figure, specifically only a small section is shown connected to the first water outlet 13), through which line water is supplied to the toilet bowl brush ring, and the second water outlet 14 is connected to the flushing line of the toilet bowl (only a small section is shown in the figure, specifically only a small section is shown connected to the second water outlet 14), through which water is supplied to the toilet bowl flushing. The first water stop component 131 and the second water stop component 141 can respectively block the first water outlet 13 and the second water outlet 14, when the first water outlet 13/the second water outlet 14 are blocked, the outlet can not discharge water, otherwise, water can be discharged. Whether the first water stop component 131 and the second water stop component 141 block the first water outlet 13 and the second water outlet 14 is controlled by the switching component 20, specifically, the pontoon 21 is lifted to drive the switching link 22 to rotate (the middle part of the switching link is rotatably connected with the device body 10, and the connecting position of the switching link is a rotation point), so as to drive the first water stop component 131 to block the first water outlet 13 or drive the second water stop component 141 to block the second water outlet 14, for example: the buoy 21 rises to drive the switching connection to rotate, at the moment, the first water stopping component 131 seals the first water outlet 13, the second water outlet 14 is in an open state, the buoy 21 falls to drive the switching connection to rotate in the opposite direction, at the moment, the second water stopping component 141 seals the second water outlet 14, and the first water outlet 13 is in an open state.
