Referring to fig. 17 and 18, the three-way valve assembly 350 includes: the three-way valve 351 includes a valve body 3511, a valve core 3512 and a sealing assembly disposed between the valve body 3511 and the valve core 3512, the valve core 3512 being rotatably mounted inside the valve body 3511, and a drive control mechanism 352 for controlling the valve core 3512 to rotate inside the valve body 3511.

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

The valve core 3512 is in a cake-shaped structure and comprises an arc curved surface and two circular planes, the two circular planes are respectively positioned at 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 in the valve body 3511. The valve core 3512 is provided with a first valve port, a second valve port and a third valve port on the arc curved surface, the first valve port and the second valve port are oppositely arranged and communicated to form a first flow channel 3501, and the first flow channel 3501 is radially arranged on the valve core 3512. The third valve port is located at one side of the first flow channel 3501 and communicates with the first flow channel 3501 to form a second flow channel 3502, and the first flow channel 3501 is disposed at a predetermined angle to the second flow channel 3502.

Then, three openings are also provided on the valve body 3511, a first opening 3503, a second opening 3504 and a third opening 3505, wherein the first opening 3503 is an inflow opening of the three-way valve 351, the second opening 3504 is a liquid outlet of the three-way valve 351, the third opening 3505 is a water outlet of the three-way valve 351, the first opening 3503 is communicated with the inside of the stirring cavity 341, the second opening 3504 is communicated with the water outlet assembly 360, and the third opening 3505 is communicated with the waste water pipe.

The sealing assembly includes four sets of gaskets 3513 and sealing rings 3514 that are stacked, wherein the four sets of gaskets 3513 are orthogonally disposed on the arc curved surface of the valve core 3512, specifically, the four sets of gaskets 3513 and sealing rings 3514 are disposed between the valve core 3512 and the first opening 3503 of the valve body 3511, between the second opening 3504 of the valve body 3511, and between the valve core 3512 and the inner wall of the valve body 3511, respectively.

The four groups of gaskets 3513 are all attached to the arc curved surface of the valve core 3512, and the valve core 3512 can be attached to the four groups of gaskets 3513 all the time when rotating, so that when the valve port of the valve core 3512 is communicated with the opening of the valve body 3511, the valve port edge of the valve core 3512 and the valve body 3511 are kept in a sealing and blocking state, and fluid or impurities are prevented from entering a gap between the valve core 3512 and the valve body 3511. And four groups of sealing rings 3514 can be respectively compressed by corresponding gaskets in the axial direction, so that the movement of the valve core 3512 in the cavity of the valve body 3511 is smoother, and meanwhile, the sealing performance between the valve core 3512 and the valve body 3511 can be ensured.

For example, when the first flow passage 3501 or the second flow passage 3502 communicates with the first opening 3503, since the joint of the circular arc curved surface of the valve body 3512 and the gasket 3513 is always tightly sealed, fluid or foreign matter cannot enter the gap between the valve body 3511 and the valve body 3512 from the joint, and at the same time, the seal ring 3514 is located between the gasket 3513 and the first opening 3503 for sealing the gap between the gasket 3513 and the first opening 3503.

With the above design, the fit clearance between the valve core 3512 and the valve body 3511 can be 0.05mm, making it difficult for fluid or impurities (e.g., juice) to enter between the valve core 3512 and the valve body 3511, preventing fouling between the valve core 3512 and the valve body 3511.

As shown in fig. 19 and 20, optionally, the sealing assembly further includes a sealing member 3515, where the sealing member 3515 is mounted on the valve core 3512 and can rotate with the valve core 3512 in the valve body 3511, so that when the valve core 3512 rotates, the edge of the valve port and the valve body 3511 are kept in a sealing and blocking state all the time, so as to prevent fluid or impurities from entering a gap between the valve core 3512 and the valve body 3511, and the sealing member 3515 is in an integrated structure.

The seal 3515 fits into the seal groove 3516, and the seal 3515 is mounted in a mosaic to the seal groove 3516 and applies a tightening force to the valve cartridge 3512 such that the seal 3515 is secured within the seal groove 3516.

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 core 3512 is installed inside the valve body 3511, the edges of the first valve port, the second valve port and the third valve port can be completely sealed with the valve body 3511, and fluid or impurities cannot enter the assembly gap between the valve core 3512 and the valve body 3511 through the edges of the first valve port, the second valve port and the third valve port of the valve core 3512, so that a clean and foreign matter-free state is always maintained between the valve core 3512 and the valve body 3511.

It will be appreciated that in some other embodiments, the second seal grooves 3516B may be omitted, the seal 3515 may be adapted to the first seal grooves 3516A, one first seal groove 3516A may be fitted with one seal 3515, and an upper surface of each seal 3515 may slightly protrude from the corresponding first seal groove 3516A, such that two circular planar edges of the valve core 3512 may be completely sealed with an inner sidewall of the valve body 3511, preventing fluid from entering an assembly gap between the two circular planar edges of the valve core 3512 and the valve body 3511.

When the valve core 3512 rotates in the cavity of the valve body 3511, the three-way valve 351 can be caused to be in a predetermined operating state, which can include a standby state, a stirring/washing state, and a drinking state.
