The valve core 32 includes a rotating shaft 321, and the reversing valve plate 40 is assembled on the rotating shaft 321. The driving member 31 has a driving shaft 311, and the driving shaft 311 extends into the valve cavity 12 and is in transmission connection with the valve core 32. The driving member 31 drives the valve core 32 to rotate, and the reversing valve plate 40 rotates together with the valve core 32. A spring is sleeved on the valve core 32 to press the reversing valve plate 40 against the water passing valve plate 50 so that the water passing valve plate 50 and the reversing valve plate 40 are in contact. Preferably, the driving member 31 can be a motor.

[0039] See Figures 1 to 2 , in one embodiment, the reversing valve plate 40 includes a mounting hole 41 that cooperates with the rotating shaft 321 and a water passing hole 42 that is arranged through. The water passing hole 42 communicates with the water inlet part 11. The water passing hole 42 can be a fan-shaped axial through hole, and the distance between the water passing hole 42 and the rotation axis is adapted to the distance between the water passing valve plate 50 and the rotation axis.

[0040] See Figures 1 to 4 , in one embodiment, the water passing valve plate 50 includes a plurality of water passing holes and a limiting hole 57 that penetrate through the water inlet end and the water outlet end of the water passing valve plate 50. The limiting hole 57 has a clearance fit with the rotating shaft 321 of the valve core 32. The valve core 32 cannot drive the water passing valve plate 50 to rotate together, and the position of the water passing valve plate 50 relative to the cover 20 remains unchanged. A notch 51 for orientation and positioning can be provided at the water outlet end of the water passing valve plate 50.

[0041] Among them, at least four water through holes are configured as functional ports, and at least two water through holes are configured as self-cleaning ports 54 to meet the expansion of more washing and care functions. The water through valve plate 50 can group the water through holes for washing and caring for the same body part of the user into one functional group. For example, it can include a functional group for hip washing and a functional group for perineum washing. Preferably, one functional group is configured with at least two functional ports and at least one self-cleaning port 54. At least two functional ports are respectively configured as at least one first cleaning port 52 and at least one second cleaning port 53. The first cleaning port 52 and the second cleaning port 53 can adapt to different flow rates to meet different washing and care requirements for the same part.

[0042] See Figures 5 to 7 , in an embodiment, on the surface of the water inlet end of the water through valve plate 50, the functional group is provided with a first water guide groove 55 communicating with the first cleaning port 52, and the first water guide groove 55 extends to a position close to the second cleaning port 53 of the same functional group or close to the second water guide groove 56 communicating with the second cleaning port 53. When the reversing valve plate 40 rotates to the two-hole cold discharge position, the water through hole 42 simultaneously communicates with the first water guide groove 55 and the second cleaning port 53. When there is a cold discharge requirement, the reversing valve plate 40 can be controlled to rotate to this position, and cold water flows through the water through hole 42 to the second cleaning port 53 and the first water guide groove 55 simultaneously, and flows into the first cleaning port 52 along the first water guide groove 55. Therefore, cold water can be discharged simultaneously through the first cleaning port 52 and the second cleaning port 53 to speed up the discharge.

[0043] Preferably, a second water guide groove 56 is provided in each functional group, and the second water guide groove 56 communicates with the second cleaning port 53. The adjacent second water guide grooves 56 of different functional groups extend circumferentially towards each other. When the reversing valve plate 40 rotates to the four-hole cold discharge position, the water through hole 42 simultaneously communicates with two first water guide grooves 55 and two second water guide grooves 56. Based on the same principle as above, when the reversing valve plate 40 rotates to this position, cold water can be discharged simultaneously through the first cleaning ports 52 and the second cleaning ports 53 of two functional groups, with a total of four drainage ports, and the drainage speed is fast.

[0044] See Figure 1 , 2, 8, and 9.
