Specifically, the three-way valve 351 is installed below the lower chamber 341B through the valve body 3511, so that the fluid inside the stirring chamber 341 can flow to different directions through the internal flow passage of the valve spool 3512, and the water outlet assembly 360 is detachably connected to the three-way valve 351.

The valve core 3512 is a round cake-shaped structure and comprises an arc curved surface and two round planes, the two round planes are respectively positioned on two sides of the arc curved surface to form the outer contour of the valve core 3512, and the valve core 3512 is matched with a cavity inside the valve body 3511. A first valve port, a second valve port and a third valve port are arranged on the arc curved surface of the valve core 3512, the first valve port and the second valve port are arranged oppositely and communicated to form a first flow passage 3501, and the first flow passage 3501 is radially arranged on the valve core 3512. The third valve port is located at one side of the first flow passage 3501 and is communicated with the first flow passage 3501 to form a second flow passage 3502, and the first flow passage 3501 and the second flow passage 3502 are arranged at a preset angle.

Moreover, the upper surface of the sealing member 3515 slightly protrudes out of the sealing groove 3516, that is, the thickness of the sealing member 3515 is slightly greater than the depth of the sealing groove 3516, so that when the valve spool 3512 is installed inside the valve body 3511, the edges of the first port, the second port and the third port can be completely sealed with the valve body 3511, and fluid or impurities cannot enter the assembly gap between the valve spool 3512 and the valve body 3511 through the edges of the first port, the second port and the third port of the valve spool 3512, so that the valve spool 3512 and the valve body 3511 are always kept in a clean and foreign-free state.
