When the water inlet 143 communicates with the first water outlet 151, the water flow passes through the water inlet 143, the first water outlet 151 and the shower pipe 92 in order to reach the top shower 91; when the water inlet 143 is communicated with the second water outlet 161, the water flow sequentially passes through the water inlet 143, the second water outlet 161 and the first hose 93 to reach the shower head 94; when the water inlet 143 is communicated with the third water outlet 162, the water flow sequentially passes through the water inlet 143, the third water outlet 162 and the second hose 95 to reach the spray gun 96; when the water inlet 143 communicates with the fourth water outlet 163, the water flows through the water inlet 143 and the fourth water outlet 163 in sequence to reach the water outlet pipe 97.

In an exemplary embodiment, as shown in fig. 2 and 3, the diverter cartridge 10 further includes a handle 72 and a barrel 71. The cylinder 71 is a cylinder and is fitted around the ring gear 42. The cylinder 71 is disposed coaxially with the ring gear 42. The cylinder 71 and the gear ring 42 are fixedly connected, and the cylinder 71 and the gear ring 42 can be in spline connection. The handle 72 is disposed outside the cylinder 71 and connected to the cylinder 71.

The gear ring 42 can be driven to rotate by the rotation of the pushing handle 72, so as to drive the rotating shaft 2 and the switching component 3 to rotate, thereby realizing the switching of the water path in the valve core. The cylinder 71 covers the first mounting hole 144, so that the faucet 80 has a more attractive appearance.

In an exemplary embodiment, as shown in FIG. 11, the number of teeth 421 on ring gear 42 is greater than the number of transmission teeth 23 on hollow shaft segment 21.

When the ring gear 42 drives the rotating shaft 2 to rotate through the planet gear 41, the rotating angle of the ring gear 42 is smaller than that of the rotating shaft 2. Thus, the gear ring 42 only needs to rotate the rotary shaft 2 by a small angle to drive the switching component 3 to rotate in place quickly.

In an exemplary embodiment, the number of teeth 421 on ring gear 42 is twice the number of transmission teeth 23 on hollow shaft section 21.

When the ring gear 42 rotates the rotating shaft 2 through the planetary gear 41, the rotating shaft 2 rotates twice as much as the ring gear 42. That is, the rotation shaft 2 makes two rotations when the ring gear 42 makes one rotation.

In the present embodiment, the switching member 3 needs to rotate 90 degrees when switching from the first position to the second position, needs to continue to rotate 90 degrees when switching from the second position to the third position, and needs to continue to rotate 90 degrees when switching from the third position to the fourth position. And every time the gear ring 42 rotates 45 degrees, the rotating shaft 2 can drive the switching component 3 to rotate 90 degrees, and the gear ring 42 only needs to rotate within the range of 135 degrees to complete the switching of the switching component 3 from the first position to the fourth position. Therefore, the handle 72 can be swung only within 135 degrees, and when the faucet 80 is mounted close to the wall and the water diversion valve core 10 is close to the wall, the handle 72 will not interfere with the wall.

In one exemplary embodiment, the planet gears 41 are each provided in two, and the first mounting holes 144 are also provided in two. Two first mounting holes 144 are provided at opposite sides of the first pipe section 141, respectively. Both first mounting holes 144 are flush with the gear teeth 23 on the hollow shaft section 21. The two planetary gears 41 are respectively disposed in the two first mounting holes 144, and the two planetary gears 41 are respectively located at opposite sides of the hollow shaft section 21.

When the two planetary gears 41 transmit the torque applied by the gear ring 42 to the hollow shaft section 21, the hollow shaft section 21 is stressed in a balanced manner and is not easy to be locked.

In an exemplary embodiment, as shown in fig. 9 and 10, the outer diameter of the first tube section 141 is smaller than the outer diameter of the second tube section 142. The diverter valve cartridge 10 also includes a pressure cap 43 and a wear washer 44. The pressure cap 43 is designed as a circular sleeve. The press cap 43 is fitted over the first pipe section 141. The press cap 43 is provided with external threads for threaded connection with the housing 85 of the faucet 80.

The inner diameter of the press cap 43 may be smaller than the outer diameter of the second pipe segment 142. The press cap 43 is located between the second pipe section 142 and the ring gear 42. A wear washer 44 is fitted over the pressure cap 43, and one end of the wear washer 44 facing the ring gear 42 abuts against the ring gear 42. As shown in fig. 10, the pressing cap 43 is further provided with a first stopper protrusion 431, and the first stopper protrusion 431 protrudes radially outward from the outer circumferential surface of the pressing cap 43. A first stop lug 431 is provided on the side of the wear washer 44 facing away from the ring gear 42. The first stop lug 431 abuts against the end of the wear washer 44 facing away from the ring gear 42. In this way, the wear-resistant washer 44 is interposed between the first stopper protrusion 431 and the ring gear 42 for reducing wear between the ring gear 42 and the press cap 43.

In an exemplary embodiment, as shown in fig. 8-10, the end cap 152 of the outlet connector 15 is further provided with a second limiting protrusion 155. The second stopper projection 155 projects radially outward from the edge of the end cap 152. A second stop lug 155 is provided at the end of the ring gear 42 facing away from the wear washer 44. The second limit bulge 155 and the anti-abrasion washer 44 can prevent the gear ring 42 from moving axially, and the gear ring 42 is prevented from being separated from the water diversion valve core 10.

In an exemplary embodiment, as shown in FIGS. 13 and 14, 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 142. 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.

As shown in fig. 13, the first rotating base 32 includes a first base 323 and a plurality of first bosses 324. The first base 323 is a substantially disk-shaped structure. The first base 323 is provided at the middle thereof with a second fitting hole 321. The shape of the second fitting hole 321 matches the shape of the cross-section of the solid shaft segment 22. The solid shaft segment 22 extends through the second assembly aperture 321.

The first boss 324 may be an arcuate boss. The first boss 324 is disposed on a side of the first base 323 adjacent to the first pad 311. The first boss 324 abuts against the first pad 311. 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 third 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. 10 and 14, 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, as shown in fig. 10 and 14, 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 section 142, 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 142, making it difficult for water to pass through the gap between the first gasket 311 and the second pipe segment 142.

In an exemplary embodiment, as shown in FIG. 14, opposite ends of the first rib 317 are connected 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 FIGS. 13 and 16, 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 16. The diameter of the second seal 35 is equal to the inner diameter of the second tube section 142. 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 second through hole 354 is provided on the second shim plate 351 to be 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.

As shown in fig. 13 and 15, the second rotation 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 rotary shaft 22, 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. 10 and 13, 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, as shown in fig. 10 and 13, the second gasket 35 further includes a second cylinder 355. The second cylinder 355 extends from the outer edge of the second pad 351 toward the second swivel base 34. The second cylinder 355 is disposed coaxially with the second sleeve 356. The outer peripheral surface of the second cylinder 355 abuts against the inner peripheral surface of the second pipe section 142, and the outward side wall of the second projection 344 abuts against the inner peripheral surface of the second cylinder 355. The second cylinder 355 strengthens the seal between the second shim plate 351 and the second tube segment 142, making it difficult for water to pass through the gap between the second shim plate 351 and the second tube segment 142.

In an exemplary embodiment, the second rib 357 is connected at opposite ends to the second sleeve 356 and the second cylinder 355, respectively. Thus, the second rib 357, the second sleeve 356, and the second cylinder 355 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, as shown in fig. 10, the water diverter cartridge 10 further includes two seal rings 6. The sealing ring 6 may be an O-ring 6. Two sealing rings 6 are sleeved on the hollow shaft section 21.

Two sealing rings 6 are distributed on opposite sides of the first mounting hole 144. This prevents water in the first pipe section 141 from leaking out of the first mounting hole 144.

In an exemplary embodiment, the hollow shaft segment 21 is further provided with a first annular groove 213 and a second annular groove 214. The first annular groove 213 and the second annular groove 214 are both arranged coaxially with the hollow shaft section 21. The two sealing rings 6 are partially inserted in the first annular groove 213 and the second annular groove 214, respectively.

The two sealing rings 6 are partially inserted into the first annular groove 213 and the second annular groove 214, respectively, to prevent the sealing rings 6 from moving axially in the hollow shaft section 21.

In an exemplary embodiment, as shown in fig. 10 and 17, the water distribution valve cartridge 10 further includes a ball stopper seat 51, a ball stopper 52, and a second elastic member 53. The ball seat 51 has a substantially circular disk shape. The ball seat 51 is disposed in the second tube section 142 and fixed to the second tube section 142. The ball seat 51 is disposed coaxially with the second tube section 142. The ball seat 51 is located between the first swivel seat 32 and the second swivel seat 34. The ball seat 51 and the second tube 142 may be snap-fit. The outer edge of the ball catch seat 51 is provided with a buckle 511, and the buckle 511 is clamped on the water inlet 143.

Through hole as shown in fig. 17, a fifth through hole 510 is formed at the middle portion of the ball striking base 51. The fifth via 510 is a via. The fifth through hole 510 has a diameter larger than the outer diameter of the first elastic member 33. The first resilient member 33 and the solid shaft segment 22 both extend through the fifth through hole 510. The ball seat 51 is recessed inwardly toward the end surface of the first rotating seat 32 to form four retaining grooves 512. The distances from the four limiting grooves 512 to the axis of the rotating shaft 2 are equal.

As shown in fig. 9, the first rotating base 32 is further provided with a blind mounting hole 325. The blind mounting hole 325 of the first swivel base 32 is located on a side of the first swivel base 32 facing the second swivel base 34. The blind mounting hole 325 extends in a direction parallel to the axis of the first rotating base 32.

The second elastic member 53 is disposed in the mounting blind hole 325. The second elastic member 53 may be a coil spring. The collision bead 52 has a substantially columnar structure. The axis of the collision bead 52 is parallel to the axis of the rotation shaft 2. As shown in fig. 17, the striking ball 52 includes a large diameter section 522 and a small diameter section 523. The large-diameter section 522 and the small-diameter section 523 are coaxially disposed, and one end of the large-diameter section 522 is connected to one end of the small-diameter section 523. The diameter of the large diameter section 522 is greater than the diameter of the small diameter section 523. The small diameter portion 523 of the collision bead 52 is inserted into the mounting blind hole 325, and the large diameter portion 522 of the collision bead 52 abuts against the collision bead seat 51. The second elastic member 53 is fitted over the small-diameter section 523. One end of the second elastic member 53 abuts against the end of the large-diameter section 522 facing the end of the small-diameter section 523, and the other end of the second elastic member 53 abuts against the bottom of the mounting blind hole 325. The end surface of the large diameter section 522 facing away from the small diameter section 523 is a spherical surface, which abuts against the ball striking seat 51.

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 132 of the partition plate 13, the large diameter portion 522 of the collision bead 52 is partially sunk into the first stopper groove 512. When the switch assembly 3 is rotated to the second position where the second through hole 354 of the second sealing gasket 35 is aligned with the second water outlet 161 of the base 16, the large diameter portion 522 of the collision ball 52 is partially sunk into the second limiting groove 512. When the switch assembly 3 is rotated to the third position where the second through hole 354 of the second sealing gasket 35 is aligned with the third water outlet 162 of the base 16, the large diameter portion 522 of the collision ball 52 is partially sunk into the third limiting groove 512. When the switch assembly 3 is rotated to the fourth position where the second through hole 354 of the second sealing gasket 35 is aligned with the fourth water outlet 163 of the base 16, the large diameter portion 522 of the collision bead 52 is partially sunk into the fourth limiting groove 512.

This makes the collision bead 52 capable of being inserted into the limit groove 512 when the switching member 3 is rotated to any one of the first position, the second position, the third position, and the fourth position, so that the switching member 3 is not easily rotated again, thereby locking the water diversion valve core 10.

After the collision bead 52 sinks into the limiting groove 512, the rotating shaft 2 applies a larger torque to the first rotating base 32, the spherical surface and the opening edge of the limiting groove 512 are mutually extruded, so that the opening edge of the limiting groove 512 applies an extrusion force to the collision bead 52, and the end surface of the collision bead 52, which abuts against the collision bead seat 51, is a spherical surface, so that the extrusion force has an axial component force which is directed to the bottom of the mounting blind hole 325. When the component force is larger than the elastic force applied by the second elastic member 53 to the collision bead 52, the collision bead 52 compresses the second elastic member 53, and the collision bead 52 can finally disengage from the limiting groove 512 to release the locking of the water diversion valve core 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. 10, two hooks 511 are provided on the ball seat 51, and the two hooks 511 are respectively provided on opposite sides of the ball seat 51.

The two buckles 511 symmetrically arranged on the ball striking seat 51 are respectively clamped on the two water inlets 143 symmetrically arranged on the second pipe section 142, and the ball striking seat 51 is more stably installed. Meanwhile, the two water inlets 143 are provided to allow water to enter simultaneously, so that the inflow rate of water can be increased.

In an exemplary embodiment, as shown in fig. 17, the ball striking base 51 is provided with a plurality of channels 513. The channel 513 is formed by an outer circumferential surface of the ball striking base 51 being depressed inward. The plurality of channels 513 are uniformly distributed on the outer edge of the ball striking base 51. The channel 513 extends in the axial direction of the ball striking seat 51. The channel 513 extends through the ball seat 51.

The water flow not only flows into the cavity between the second rotary seat 34 and the ball-contacting seat 51 along the fifth through hole 510 of the ball-contacting seat 51, but also flows into the cavity between the second rotary seat 34 and the ball-contacting seat 51 along the channels 513, so that the water flow of the second water outlet 161, the third water outlet 162 and the fourth water outlet 163 is increased.

In an exemplary embodiment, as shown in fig. 7, the base 16 is further provided with a second shaft hole 164, and the second shaft hole 164 is a blind hole. The second shaft hole 164 is provided at an end of the base 16 facing the partition 13. The second shaft hole 164 is disposed coaxially with the rotary shaft 2.
