A switch valve includes a fixation portion and a water diversion plate, the fixation portion, a water diversion cavity connected to an inlet waterway, at least two diversion waterways, and a water diversion plate. A universal driving shaft is rotatably connected to the fixation portion and is inserted to the water diversion cavity. The driving mechanism is connected to the universal driving shaft. The water diversion plate and the universal driving shaft rotate synchronously. The bottom of the water diversion cavity is fixedly disposed with a first gear ring. The water diversion plate is fixedly disposed with a second gear ring which engages with the first gear ring. When the driving mechanism drives the water diversion plate to rotate in a preset angle, it slides along the universal driving shaft. The inlet waterway is switched to connect to the diversion waterways by the rotation of the water diversion plate.
