In an exemplary embodiment, as shown in FIGS. 16 and 17, the first gasket 31 includes a first pad 311 and a plurality of first ribs 317. The first pad 311 is configured as a substantially circular flat plate. The first pad 311 covers the partition 13. The diameter of the first gasket 31 is equal to the inner diameter of the second tube section 112. The first pad 311 is provided at a middle portion thereof with a first fitting hole 312. In this embodiment, the solid shaft segment 22 is generally semi-circular in cross-section, and the first assembly aperture 312 is shaped to match the cross-sectional shape of the solid shaft segment 22, with the solid shaft segment 22 extending through the first assembly aperture 312. The first through hole 314 is provided on the first shim plate 311, and is located outside the first fitting hole 312.

The first rib 317 is disposed on a side of the first pad 311 adjacent to the first rotating base 32. The first rib 317 is a bar-shaped protrusion. The number of first ribs 317 may be 4. The first ribs 317 are radially arranged around the first mounting hole 312.

The plurality of first bosses 324 are evenly distributed around the second fitting hole 321. The number of the first bosses 324 may be 4. The second through-hole 322 is provided on one of the first bosses 324. There is a gap between every two adjacent first protrusions 324, and each first rib 317 extends into one gap.

Since the first rib 317 extends into the gap between two adjacent first protrusions 324, when the rotating shaft 2 rotates the first rotating base 32, the first protrusions 324 drive the entire first sealing gasket 31 to rotate by pushing the first rib 317 to rotate.

In an exemplary embodiment, as shown in FIG. 17, the first gasket 31 further includes a first sleeve 316. The first sleeve 316 extends from the periphery of the first fitting hole 312 of the first shim plate 311 toward the first swivel 32. The first sleeve 316 may be a cylinder. The first sleeve 316 is fitted over the solid shaft section 22, and the inner circumferential surface of the first sleeve 316 is closely attached to the outer circumferential surface of the solid shaft section 22. The first sleeve 316 strengthens the seal between the first backing plate 311 and the solid shaft segment 22, making it difficult for water to pass through the gap between the first backing plate 311 and the solid shaft segment 22.

In an exemplary embodiment, the first gasket 31 further includes a first cylinder 315. The first cylinder 315 extends from the outer edge of the first pad 311 toward the first swivel 32. The first cylinder 315 is disposed coaxially with the first sleeve 316. The outer peripheral surface of the first cylinder 315 abuts against the inner peripheral surface of the second pipe segment 112, and the outward side wall of the first protrusion 324 abuts against the inner peripheral surface of the first cylinder 315. The first cylinder 315 enhances the seal between the first gasket 311 and the second pipe segment 112, making it difficult for water to pass through the gap between the first gasket 311 and the second pipe segment 112.

In an exemplary embodiment, opposite ends of the first rib 317 are coupled to the first sleeve 316 and the first cylinder 315, respectively. After the connection, the first rib 317, the first sleeve 316 and the first cylinder 315 correspond to reinforcing rib plates connected with each other, and the structural strength of the whole first gasket 31 is enhanced, so that the first gasket 31 is not easily deformed.

In one exemplary embodiment, as shown in FIG. 22, the second gasket 35 includes a second pad 351 and a plurality of second ribs 357. The second pad plate 351 is configured as a substantially circular flat plate. The second pad 351 is covered on the base 12. The diameter of the second gasket 35 is equal to the inner diameter of the second tube section 112. The middle portion of the second shim plate 351 is provided with a third fitting hole 352. In this embodiment, the solid shaft segment 22 is generally semi-circular in cross-section, and the third assembly aperture 352 is shaped to match the cross-sectional shape of the solid shaft segment 22, with the solid shaft segment 22 extending through the third assembly aperture 352. The third through hole 354 is provided on the second shim plate 351 and is located outside the third fitting hole 352.

The second rib 357 is disposed on a side of the second pad 351 adjacent to the second swivel mount 34. The second rib 357 is a bar-shaped protrusion. The number of the second ribs 357 may be 4. The plurality of second ribs 357 are radially distributed around the second fitting hole 321.

The second swivel base 34 includes a second base 343 and a plurality of second protrusions 344. The second base 343 is of a generally circular disk structure. The middle portion of the second base 343 is provided with a fourth fitting hole 341. The shape of the fourth fitting hole 341 matches the shape of the cross section of the solid shaft segment 22. The solid shaft segment 22 extends through the fourth assembly hole 341.

The second projection 344 may be an arcuate boss. The second protrusion 344 is disposed on a side of the second base 343 close to the second pad 351. The second protrusion 344 abuts against the second pad 351. The plurality of second protrusions 344 are uniformly distributed around the fourth fitting holes 341. The number of the second protrusions 344 may be 4. The fourth through-hole 342 is provided on one of the second bosses 344. There is a gap between every two adjacent second protrusions 344, and each second rib 357 extends into one gap.

Since the second rib 357 extends into the gap between two adjacent second protrusions 344, when the second rotary seat 34 is rotated by the shaft 2, the second protrusions 344 drive the entire second gasket 35 to rotate by pushing the second rib 357.

In an exemplary embodiment, as shown in FIG. 22, the second seal 35 further includes a second sleeve 356. The second sleeve 356 extends from the periphery of the third fitting hole 352 of the second shim plate 351 toward the second swivel base 34. The second sleeve 356 may be a cylinder. The second sleeve 356 is fitted over the solid shaft segment 22, with the inner circumferential surface of the second sleeve 356 abutting the outer circumferential surface of the solid shaft segment 22. The second sleeve 356 enhances the seal between the second backing plate 351 and the solid shaft segment 22, making it difficult for water to pass through the gap between the second backing plate 351 and the solid shaft segment 22.

In an exemplary embodiment, the second gasket 35 further includes a second cylinder 356. The second cylinder 356 extends from the outer edge of the second pad 351 toward the second turret 34.

The outer peripheral surface of the second cylinder 356 abuts against the inner peripheral surface of the second pipe segment 112, and the outward side wall of the second projection 344 abuts against the inner peripheral surface of the second cylinder 356. The second cylinder 356 enhances the seal between the second shim plate 351 and the second tube segment 112, making it difficult for water to pass through the gap between the second shim plate 351 and the second tube segment 112.

In an exemplary embodiment, the second rib 357 is connected at opposite ends to the second sleeve 356 and the second cylinder 356, respectively. After such connection, the second rib 357, the second sleeve 356, and the second cylinder 356 correspond to reinforcing ribs connected to each other, which enhances the overall structural strength of the second gasket 35, so that the second gasket 35 is not easily deformed.

In an exemplary embodiment, the valve cartridge 10 further comprises two first sealing rings 4. The first sealing ring 4 may be an O-ring. Two first sealing rings 4 are all sleeved on the hollow shaft section 21. The inner edge of the first seal ring 4 abuts against the outer peripheral surface of the hollow shaft section 21, and the outer edge of the first seal ring 4 abuts against the inner peripheral surface of the first pipe section 111. Two first sealing rings 4 are distributed on opposite sides of the strip groove 113. This prevents water in the first pipe section 111 from leaking out of the groove 113.

In an exemplary embodiment, as shown in fig. 4 and 8, two annular grooves 214 are also provided on the hollow shaft section 21. The annular groove 214 is arranged coaxially with the hollow shaft section 21. The two first sealing rings 4 are partially inserted into the two annular grooves 214, respectively.

The partial insertion of the first sealing ring 4 into the annular groove 214 prevents axial play of the first sealing ring 4 in the hollow shaft section 21.

In an exemplary embodiment, as shown in FIG. 18, a blind mounting hole 325 is provided at the top end of the first boss 324. The top surface of the first protrusion 324 is recessed away from the first pad 311 to form the blind mounting hole 325. The mounting blind hole 325 opens toward the first shim plate 311. As shown in fig. 16, the first pad 311 is further provided with a fifth through hole 313. The fifth through hole 313 and the mounting blind hole 325 are aligned with each other. The diameter of the fifth through hole 313 is the same as the diameter of the mounting blind hole 325.

As shown in fig. 3 and 4, the valve core 10 further includes a stopper pin 5 and a second elastic member 6. The second elastic member 6 is disposed in the mounting blind hole 325. The second elastic member 6 may be a coil spring. The stopper pin 5 has a substantially columnar structure. The axis of the stopper pin 5 is parallel to the axis of the rotating shaft 2, and as shown in fig. 20, the stopper pin 5 includes a large-diameter section 51 and a small-diameter section 52. The large-diameter section 51 and the small-diameter section 52 are coaxially disposed, and one end of the large-diameter section 51 is connected to one end of the small-diameter section 52. The diameter of the large-diameter section 51 is larger than that of the small-diameter section 52. The small-diameter section 52 of the stopper pin 5 is inserted into the mounting blind hole 325, and the large-diameter section 51 of the stopper pin 5 passes through the fifth through hole 313 to abut against the partition plate 13. The second elastic member 6 is fitted over the small-diameter section 52. One end of the second elastic element 6 abuts against the end of the large-diameter section 51 facing the end of the small-diameter section 52, and the other end of the second elastic element 6 abuts against the bottom of the mounting blind hole 325. The end surface of the large-diameter section 51 facing away from the small-diameter section 52 is a spherical surface, which abuts against the partition plate 13.

As shown in fig. 4, 3 grooves 132 are provided on a surface of the partition plate 13 facing the stopper pin 5. The distance from the 3 grooves 132 to the axis of the rotating shaft 2 is equal to the distance from the limit pin 5 to the axis of the rotating shaft 2.

When the switch assembly 3 is rotated to the first position where the first through hole 314 of the first sealing gasket 31 is aligned with the hole 133 of the partition plate 13, the large-diameter portion 51 of the stopper pin 5 is partially recessed into the first recess 132. When the switch assembly 3 is rotated to the second position where the third through hole 354 of the second sealing gasket 35 is aligned with the first water outlet 121 of the base 12, the large-diameter portion 51 of the stopper pin 5 is partially sunk into the second groove 132. When the switch assembly 3 is rotated to the third position where the third through hole 354 of the second sealing gasket 35 is aligned with the second water outlet 122 of the base 12, the large-diameter portion 51 of the stopper pin 5 is partially sunk into the third groove 132. This allows the restricting pin 5 to be inserted into the groove 132 when the switch block 3 is rotated to any one of the first, second and third positions, so that the switch block 3 is not easily rotated again, thereby locking the valve cartridge 10.

After the limit pin 5 sinks into the groove 132, the rotating shaft 2 applies a large torque to the first rotating seat 32, the spherical surface and the opening edge of the groove 132 are mutually pressed, so that the opening edge of the groove 132 applies a pressing force to the limit pin 5, and the pressing force has an axial component force which points to the bottom of the mounting blind hole 325 because the end surface of the limit pin 5, which abuts against the partition plate 13, is a spherical surface. When the component force is larger than the elastic force applied by the second elastic element 6 to the stopper pin 5, the stopper pin 5 compresses the second elastic element 6, and the stopper pin 5 can finally disengage from the groove 132 to unlock the valve element 10. In addition, start when carrying out the water route and feel great, can promote user experience.

In an exemplary embodiment, as shown in fig. 7, the base 12 is further provided with a second shaft hole 123, and the second shaft hole 123 is a blind hole. The second shaft hole 123 is provided at an end of the base 12 facing the partition 13. The second shaft hole 123 is coaxially disposed with the rotation shaft 2. The solid shaft segment 22 of the rotating shaft 2 is inserted into the second shaft hole 123 and is in clearance fit with the second shaft hole 123.

The end of the solid shaft section 22 facing away from the hollow shaft section 21 is constrained by the second shaft aperture 123, making the shaft 2 more smooth when rotating.

In an exemplary embodiment, as shown in FIG. 9, the shunt valve 101 further comprises a handle 9 and a third sleeve 8. The third sleeve 8 is a cylinder and is sleeved on the first pipe section 111. The third sleeve 8 can rotate around the first pipe section 111. The outward end of the toggle piece 7 is connected to the third sleeve 8. The driver 7 may be a screw, and the third sleeve 8 is provided with a threaded hole 81, and the driver 7 is screwed into the threaded hole 81 and inserted into the blind hole of the hollow shaft section 21. The handle 9 is arranged outside the third cylinder body and is connected with the third cylinder body.

Can drive through the rotation that pushes away handle 9 and dial piece 7 and slide along strip groove 113, and then drive pivot 2 and switching module 3 and rotate to realize the switching of the water route in the case 10. The third sleeve 8 covers the strip groove 113, making the shunt valve 101 more aesthetically pleasing.
