The outer peripheral surface of the stationary disc 15 abuts against the inner peripheral surface of the cylinder 12. A stationary disc 15 overlies the base 14. The end of the stationary plate 15 facing the base 14 is provided with a limiting aperture 154. The end of the base 14 facing the stationary plate 15 is provided with a stop rib 144. The stop ribs 144 are inserted into the stop holes 154 such that the stationary plate 15 cannot rotate relative to the base 14. The stationary disc 15 is further provided with a third through hole 152, a fourth through hole 153 and a first channel 151. The first channel 151 extends from the outer peripheral surface of the stationary disc 15 to an end surface of the stationary disc 15 facing away from the end of the base 14. The third through hole 152 and the fourth through hole 153 each extend vertically through the stationary plate 15. The third through hole 152 and the fourth through hole 153 are disposed off-center from the stationary disk 15. The first through hole 142 and the third through hole 152 on the base 14 are aligned such that the first through hole 142 and the third through hole 152 are connected. The second through hole 143 and the fourth through hole 153 on the base 14 are aligned such that the second through hole 143 and the fourth through hole 153 are connected.

As shown in fig. 5 and 6, the cylinder 12 is provided with a first water inlet 135, a second water inlet 136, a third water inlet 137 and a strip groove 134. A slot 134 is provided in a sidewall of the end of the cylinder 12 facing away from the base 14. A slot 134 extends through the sidewall of the cylinder 12. The grooves 134 extend in the circumferential direction of the cylinder 12. The first water inlet 135, the second water inlet 136 and the third water inlet 137 are all located on an end of the cylinder 12 near the base 14. The first water inlet 135, the second water inlet 136 and the third water inlet 137 all extend radially through the sidewall of the cylinder 12. The first water inlet 135 and the second water inlet 136 are equidistant from the base 14 and are each greater than the distance between the third water inlet 137 and the base 14. The third water inlet 137 is flush with the stationary disc 15, and the third water inlet 137 is aligned with an opening of the first passage 151 on the outer circumferential surface of the stationary disc 15. Thus, the third water inlet 137 is communicated with the first passage 151.

Thus, as shown in fig. 8, the cylinder 12 and the stationary plate 15 enclose a cylindrical cavity 11. The cylindrical cavity 11 comprises a first end 112 and a second end 111 opposite the first end 112, the first end 112 of the cylindrical cavity 11 being the end thereof facing away from the stationary disc 15, the second end 111 of the cylindrical cavity 11 being the end thereof adjacent to the stationary disc 15. The opening of the second end 112 of the cylinder 12 is the outlet 113 of the cylindrical cavity 11. The end face of the second end 111 of the cylindrical cavity 11 is the end face of the stationary disc 15 facing away from the end of the base 14.

As shown in fig. 12, 14 and 16, the housing 1 is further provided with a first outer water outlet flow passage 114, a second outer water outlet flow passage 115 and an outer water inlet flow passage 116, which are all communicated with the columnar cavity 11.

As shown in fig. 16, the second outer water outlet flow passage 115 includes a second through hole 143 on the base 14 and a fourth through hole 153 on the stationary plate 15. As shown in fig. 12, the outer water inlet flow passage 116 includes a third water inlet 137 on the cylinder 12 and a first channel 151 on the stationary plate 15.

As shown in fig. 9 and 10, the rotating column 2 includes a turntable 23, a first rotating sleeve 24, and a second rotating sleeve 25, which are sequentially connected. The turntable 23, the first rotating sleeve 24 and the second rotating sleeve 25 are connected together in sequence. The turntable 23 is substantially disc-shaped. The turntable 23 may be made of ceramic. The turntable 23 is disposed to rotate within the cylinder 12 and is disposed coaxially with the cylinder 12. As shown in FIG. 6, the turntable 23 is flush with the first and second water inlets 135, 136 on the cylinder 12. The turntable 23 is in clearance fit with the cylinder 12, and the turntable 23 can rotate around its own axis. The turntable 23 covers the side of the stationary disc 15 facing away from the base 14. As shown in fig. 18 and 19, the turntable 23 is provided with a second passage 232 and an inner water inflow passage 231. A second passageway 232 extends through opposite ends of the turntable 23. The opening of the second channel 232 at the end of the turntable 23 adjacent to the stationary disc 15 is offset from the axis of the turntable 23. The inner water inflow channel 231 extends from the end surface of the turntable 23 toward the stationary disk 15 onto the outer peripheral surface of the turntable 23. The inner water inlet channel 231 may be configured as a notch on the outer edge of the end of the turntable 23 facing the end of the stationary disc 15.

As shown in fig. 7 and 21, the first rotor 24 is a circular cylinder. A first sleeve 24 is disposed within the cylinder 12 and is disposed coaxially with the cylinder 12. The first sleeve 24 is in a clearance fit with the barrel 12. The first sleeve 24 is rotatable within the cylinder 12 about its own axis. One end of the first sleeve 24 is connected to the end of the turntable 23 facing away from the stationary disc 15. The first sleeve 24 has an inner bore 245 therein. The bore 245 extends axially through the first sleeve 24. The inner bore 245 of the first hub 24 communicates with the second passage 232 of the turntable 23.

As shown in fig. 12 and 22, the second rotor 25 is a circular cylinder. The second rotating sleeve 25 is disposed within the cylinder 12 and is disposed coaxially with the cylinder 12. The second sleeve 25 is in a clearance fit with the cylinder 12. The second rotating sleeve 25 can rotate around its own axis inside the cylinder 12. One end of the second sleeve 25 is connected to the end of the first sleeve 24 facing away from the turntable 23. The second sleeve 25 has an inner bore 258 therein, the bore 258 extending axially through the second sleeve 25. The inner bore 258 of the second sleeve 25 communicates with the inner bore 245 of the first sleeve 24. A first blind hole 253 is provided in the outer peripheral surface of the second sleeve 25, and the first blind hole 253 is aligned with the slot 134 in the barrel. The opening of the end of the second rotating sleeve 25 facing away from the first rotating sleeve 24 is a third water outlet 211.

As shown in fig. 9, the rotation column 2 includes a top end 21 and a bottom end 22 opposite to the top end 21. In this embodiment, the top end 21 of the rotating post 2 is the end near the second rotating sleeve 25, and the bottom end 22 of the rotating post 2 is the end near the turntable 23. The end face of the bottom end 22 of the rotating column 2 is the end face of the turntable 23 facing the stationary disc 15. An inner water inlet flow path 231 and an inner water outlet flow path 212 are formed on the rotary column 2. The inner water inlet flow passage 231 is provided on the turntable 23. The inner water outlet flow passage 212 comprises a second passage 232 of the turntable 23, an inner hole 245 of the first rotating sleeve 24 and an inner hole 258 of the second rotating sleeve 25 which are communicated in sequence.

As shown in fig. 4, the toggle member 36 has a straight bar shape. One end of the toggle member 36 is inserted into the first blind hole 253 of the second rotating sleeve 25, and the other end extends out of the cylinder 12 through the slot 134 in the cylinder 12.

The toggle piece 36 is pushed to slide along the strip groove 134 from the side surface of the shell 1, and the toggle piece 36 drives the rotary column 2 to rotate around the axis of the rotary column 2, so that the rotary column 2 switches the waterway in the water diversion valve core 10.

As shown in fig. 11 and 12, when the rotary column 2 rotates to the first position, the opening of the outer water inlet channel 116 on the end surface of the second end 111 of the cylindrical cavity 11 (i.e., the opening of the first channel 151 on the end surface of the stationary disc 15 facing the turntable 23) is aligned with the opening of the inner water outlet channel 212 on the rotary column 2 on the end surface of the bottom end 22 of the rotary column 2 (i.e., the opening of the second channel 232 on the end surface of the turntable 23 facing the stationary disc 15), and the third water inlet 137 and the third water outlet 211 are connected. The water flow can enter the water diversion valve core 10 from the third water inlet 137, then sequentially flows through the outer water inlet flow channel 116 and the inner water outlet flow channel 212, and finally flows out from the third water outlet 211 at the tail end of the inner water outlet flow channel 212. That is, the water flow enters from the third water inlet 137 and sequentially flows through the first passage 151, the second passage 232, the inner hole 245 of the first rotary sleeve 24 and the inner hole 258 of the second rotary sleeve 25, and finally flows out from the third water outlet 211. At this time, the inner water inlet flow path 231 of the rotary plate 23 is offset from the third through hole 152 and the fourth through hole 153 of the stationary plate 15, so that the rotary plate 23 blocks the water path between the first water inlet 135 and the first water outlet 145 and the water path between the second water inlet 136 and the second water inlet 146.

As shown in fig. 13 and 14, when the rotary column 2 rotates to the second position, the opening of the inner water inlet channel 231 on the rotary column 2 on the bottom surface of the rotary column 2 (i.e., the opening of the inner water inlet channel 231 on the rotary disk 23 on the end surface facing the stationary disk 15) is aligned with the opening of the first outer water outlet channel 114 on the housing 1 on the end surface of the second end 111 of the cylindrical cavity 11 (i.e., the opening of the third through hole 152 on the stationary disk 15 on the end surface facing the rotary disk 23) and the opening of the inner water inlet channel 231 on the rotary column 2 on the outer circumferential surface of the rotary column 2 is aligned with the first water inlet 135 on the housing 1, and the first water inlet 135 and the first water outlet 145 are connected. The water flow can enter the water diversion valve core 10 from the first water inlet 135, then sequentially flows through the inner water inlet flow channel 231 and the first outer water outlet flow channel 114, and finally flows out from the first water outlet 145 at the tail end of the first outer water outlet flow channel 114. That is, in the present embodiment, the water flow enters from the first water inlet 135 and sequentially flows through the inner water inlet flow channel 231, the third through hole 152 and the first through hole 142, and finally flows out from the first water outlet 145. At this time, the inner water inlet channel 231 on the turntable 23 is staggered with the fourth through hole 153 on the stationary disc 15, the first channel 151 on the turntable 23 is staggered with the second channel 232 on the stationary disc 15, the turntable 23 closes the second water inlet 136, and simultaneously blocks the water path between the third water inlet 137 and the third water outlet 211.

As shown in fig. 15 and 16, when the rotary column 2 rotates to the third position, the opening of the inner water inlet channel 231 on the rotary column 2 on the bottom surface of the rotary column 2 (i.e., the opening of the inner water inlet channel 231 on the rotary disk 23 on the end surface facing the stationary disk 15) is aligned with the opening of the second outer water outlet channel 115 on the housing 1 on the end surface of the second end 111 of the cylindrical cavity 11 (i.e., the opening of the fourth through hole 153 on the stationary disk 15 on the end surface facing the rotary disk 23) and the opening of the inner water inlet channel 231 on the rotary column 2 on the outer circumferential surface of the rotary column 2 is aligned with the second water inlet 136 on the housing 1, and the second water inlet 136 and the second water outlet 146 are connected. The water flow can enter the water diversion valve core 10 from the second water inlet 136, then sequentially flows through the inner water inlet flow channel 231 and the second outer water outlet flow channel 115, and finally flows out from the second water outlet 146 at the tail end of the second outer water outlet flow channel 115. That is, in the present embodiment, the water flow enters from the second water inlet 136 and sequentially flows through the inner water inlet flow channel 231, the fourth through hole 153 and the second through hole 143, and finally flows out from the second water outlet 146. At this time, the inner water inlet channel 231 on the turntable 23 is offset from the third through hole 152 on the stationary disk 15, and the first channel 151 on the turntable 23 is offset from the second channel 232 on the stationary disk 15. The turntable 23 blocks the waterway between the first water inlet 135 and the first water outlet 145 and the waterway between the third water inlet 137 and the third water outlet 211.

In the present embodiment, the first water inlet 135, the second water inlet 136, and the third water inlet 137 of the water diversion valve core 10 are all communicated with the water mixing valve core 42 through the water mixing flow passage 411. The mixing spool 42 simultaneously injects water to the first, second and third water inlets 135, 136 and 137 through the mixing water flow passage 411.

As shown in fig. 3, a water outlet pipe assembly 9 is also arranged below the tap 4. The outlet pipe assembly 9 includes a diverter joint 90, a first tubular 93 and a second tubular 94. The diverter sub 90 includes a tubular string 92 and a water outlet pipe 91. One end of the water outlet pipe 91 is connected to the outer circumferential surface of the pipe string 92. The upper end of the column 92 is connected to the housing 41 of the faucet 4. The pipe string 92 is located directly below the water diversion valve spool 10. The split joint 90 is provided with a first water outlet flow passage 95 and a second water outlet flow passage 96. The first outlet flow passage 95 extends from the upper end of the pipe string 92 to the end of the outlet pipe 91 facing away from the pipe string 92. The second outlet flow passage 96 extends axially through the tubular string 92.

One end of the first circular tube 93 is inserted into the housing 41 to be connected to the first water outlet 145 of the water diversion valve core 10, and the other end of the first circular tube 93 is inserted into the first water outlet flow passage 95 to be connected to the first water outlet flow passage 95. One end of the second circular tube 94 is inserted into the housing 41 to be communicated with the second water outlet 146 of the water diversion valve core 10, and the other end of the second circular tube 94 is inserted into the second water outlet flow passage 96 to be communicated with the second water outlet flow passage 96. The lower end of the tubular string 92 also has an interface for connection to the hose 6 such that the end of the second outlet flow passage 96 facing away from the second tubular 94 can be connected to the hose 6.

In this way, the first water outlet 145 is sequentially communicated with the water outlet pipe 91 through the first circular pipe 93 and the first water outlet flow channel 95, the second water outlet 146 is sequentially communicated with the shower head 8 through the second circular pipe 94, the second water outlet flow channel 96 and the hose 6, and the third water outlet 211 is communicated with the top shower 7 through the shower pipe 5 connected to the water diversion valve core 10.

When the first water inlet 135 is communicated with the first water outlet 145, water flows sequentially through the first water inlet 135 and the first water outlet 145 to reach the water outlet pipe 91; when the second water inlet 136 is communicated with the second water outlet 146, water flows sequentially through the second water inlet 136, the second water outlet 146 and the hose 6 to reach the shower head 8; when the third water inlet 137 is in communication with the third water outlet 211, water flows sequentially through the third water inlet 137, the third water outlet 211 and the shower pipe 5 to the top shower 7.

In one exemplary embodiment, as shown in fig. 8 and 24, the cylinder 12 includes a first tube segment 131, a second tube segment 132, and a third tube segment 133 that are coaxially disposed. The first pipe segment 131, the second pipe segment 132, and the third pipe segment 133 are connected together in sequence. The inner diameters of the first, second and third tube sections 131, 132, 133 decrease in sequence. The base 14 is disposed at an end of the first tube segment 131 facing away from the second tube segment 132. Both the stationary disc 15 and the turntable 23 are disposed within the first tube section 131.

As shown in fig. 7 and 21, the first sleeve 24 includes a first sleeve 241 and a first collar 242. The outer diameter of the first sleeve 241 is slightly smaller than the inner diameter of the second tube section 132. The first sleeve 241 extends from the first tube segment 131 into the second tube segment 132. A first collar 242 is provided on one end of the first sleeve 241 in the first tube segment 131. The first collar 242 protrudes radially outwardly from the outer circumferential surface of the first sleeve 241. The outer diameter of the first collar 242 is slightly smaller than the inner diameter of the first tube segment 131. The first collar 242 is sandwiched between the end face of the turntable 23 and the end face of the second tube section 132.

Because the first collar 242 is sandwiched between the end face of the turntable 23 and the end face of the second pipe section 132, the first sleeve 24 can only rotate about the axis and cannot move axially, preventing the first sleeve 24 from exiting the cylinder 12.

As shown in fig. 7 and 22, the second rotating sleeve 25 includes a second sleeve 251 and a second collar 257. The outer diameter of the second sleeve 251 is slightly smaller than the inner diameter of the third tube segment 133. The second sleeve 251 extends from the second tube segment 132 into the third tube segment 133. A second collar 257 is disposed on an end of the second sleeve 251 that is located in the second tube segment 132. The second collar 257 protrudes radially outward from the outer circumferential surface of the second sleeve 251. The outer diameter of the second collar 257 is slightly smaller than the inner diameter of the second tube section 132. The second collar 257 is sandwiched between the end face of the first sleeve 241 and the end face of the third tube segment 133.

Since the second collar 257 is sandwiched between the end face of the second collar 257 and the end face of the third pipe segment 133, the second sleeve 25 can only rotate about the axis and cannot move axially, preventing the second sleeve 25 from coming out of the cylinder 12.

In an exemplary embodiment, as shown in fig. 7, 22, 24, the second swivel 25 further comprises a connecting tube 252. The connecting tube 252 is a straight circular tube. The outer diameter of the connection tube 252 is smaller than the outer diameter of the second sleeve 251. The connection pipe 252 is disposed coaxially with the second sleeve 251. The connection pipe 252 is provided at an end of the second sleeve 251 facing the first sleeve 241. Two connecting holes 255 are symmetrically arranged on the connecting pipe 252. The connection holes 255 radially penetrate the wall of the connection tube 252. The outer diameter of the connection tube 252 is also smaller than the inner diameter of the first sleeve 241. The connection pipe 252 is inserted into the first sleeve 241.

As shown in fig. 7, 21 and 24, two pin grooves 243 are also provided on the inner wall of the first sleeve 241. The two pin grooves 243 are symmetrically disposed at one end of the first sleeve 241 near the second sleeve 251. The pin groove 243 extends from an end of the first sleeve 241 adjacent to the second sleeve 251 in a direction away from the second sleeve 251. The two pin grooves 243 are aligned with the two connection holes 255 of the connection pipe 252, respectively.

As shown in fig. 7 and 24, the rotation post 2 further includes a positioning pin 26. The positioning pin 26 is in a straight strip shape. The outer diameter of the locating pin 26 is smaller than the inner diameter of the connecting hole 255 and the width of the pin slot 243. The positioning pins 26 pass through the two connecting holes 255 in sequence. The two ends of the positioning pin 26 extend out of the connection pipe 252 and into the two pin grooves 243, respectively.

The positioning pin 26 connects the first sleeve 241 and the second sleeve 251 such that the second sleeve 251 rotates to rotate the first sleeve 241.

Further, as shown in fig. 19, the turntable 23 is further provided with a plurality of limit grooves 233. The number of the limit grooves 233 may be 4. The plurality of limit grooves 233 are uniformly distributed on an edge of the end of the turntable 23 facing the first rotating sleeve 24.

As shown in fig. 21, a plurality of limiting projections 244 are also provided on the first collar 242 of the first sleeve 24. The limit projection 244 projects from the first collar 242 toward the turntable 23. The plurality of spacing projections 244 are evenly distributed over the first collar 242. The number of the limit protrusions 244 is the same as the number of the limit grooves 233. The limit protrusions 244 are arranged in one-to-one correspondence with the limit grooves 233. The limit projection 244 is inserted into the limit groove 233 corresponding thereto.

Since the limiting protrusion 244 is inserted into the limiting groove 233, the first rotating sleeve 24 can drive the rotating disc 23 to rotate around its own axis.

Further, as shown in fig. 22 and 24, the outer peripheral surface of the first sleeve 241 is recessed radially inwardly to form a second blind hole 247. Is disposed in the first sleeve 241 adjacent to the first collar 242.

As shown in fig. 7, 23, 24, the water diversion valve core 10 further includes a shift pin 34 and an elastic member 33. The elastic member 33 is disposed in the second blind hole 247. The elastic member 33 may be a coil spring. The shift pin 34 has a substantially columnar structure. The axis of the shift pin 34 is perpendicular to the axis of the first sleeve 241, and the shift pin 34 includes a large diameter section 341 and a small diameter section 342. The large diameter section 341 and the small diameter section 342 are coaxially disposed, and one end of the large diameter section 341 is connected to one end of the small diameter section 342. The diameter of the large diameter section 341 is larger than the diameter of the small diameter section 342. The small diameter section 342 of the shift pin 34 is inserted into the second blind bore 247 and the large diameter section 341 of the shift pin 34 extends out of the second blind bore 247 against the second tube section 132. The elastic member 33 is fitted over the small diameter section 342. One end of the elastic member 33 abuts against an end of the large diameter section 341 facing one end of the small diameter section 342, and the other end of the elastic member 33 abuts against the bottom of the second blind hole 247. The end surface of the large diameter section 341 facing away from the small diameter section 342 is a spherical surface, which abuts against the second pipe section 132.

The second pipe segment 132 is provided with 3 shift grooves 138 on its inner peripheral wall. The shift position groove 138 extends from the second tube segment 132 toward one end of the first tube segment 131 in a direction away from the first tube segment 131. The 3 shift slots 138 are in the same plane perpendicular to the axis of the second tube segment 132.

When the rotation post 2 is rotated to the first position, the large diameter portion 341 of the shift pin 34 is partially caught in the first shift groove 138. When the rotation post 2 is rotated to the second position, the large diameter portion 341 of the shift pin 34 is partially caught in the second shift groove 138. When the rotation post 2 is rotated to the third position, the large diameter portion 341 of the shift pin 34 is partially caught in the third shift groove 138. This allows the shift pin 34 to be inserted into the shift groove 138 when the rotation column 2 is rotated to any one of the first position, the second position, and the third position, so that the rotation column 2 is not easily rotated again, thereby locking the state of the water diversion valve core 10.

After the gear pin 34 has been inserted into the gear groove 138, a large torque is applied to the rotary post 2, and the spherical surface of the gear pin 34 and the opening edge of the gear groove 138 are pressed against each other, so that the opening edge of the gear groove 138 applies a pressing force to the gear pin 34, which has an axial component force that is directed to the bottom of the second blind hole 247. When the component force is greater than the elastic force applied to the shift pin 34 by the elastic member 33, the shift pin 34 compresses the elastic member 33, and the shift pin 34 can finally be disengaged from the shift groove 138 to unlock the water diversion valve core 10. In addition, the arrangement can further enable the starting hand feeling to be larger when the water diversion valve core 10 is started, and user experience is improved.

In one exemplary embodiment, as shown in FIG. 4, the diverter valve cartridge 10 further includes a handle 37 and a barrel 38. The cylinder 38 is cylindrical and is sleeved on the third pipe section 133. The barrel 38 is in clearance fit with the third tube segment 133. The barrel 38 is rotatable about the third tube segment 133. The outwardly facing end of the toggle member 36 is connected to the barrel 38. The toggle member 36 may be a screw, preferably a countersunk screw, and the cylinder 38 is provided with a screw hole 381, and the toggle member 36 is screwed into the screw hole 381 to be inserted into the first blind hole 253 of the second rotator 25. The handle 37 is disposed outside the cylinder 38 and fixedly connected to the cylinder 38. The handle 37 is of flat plate construction, the handle 37 being parallel to the axis of the barrel 38.

The toggle piece 36 can be driven to slide along the strip groove 134 by the rotation of the pushing handle 37, so that the rotating column 2 is driven to rotate, and the switching of the waterway in the water diversion valve core 10 is realized. At the same time, the barrel 38 also covers the slot 134, making the appearance more aesthetically pleasing.

In an exemplary embodiment, as shown in fig. 7 and 10, the water diversion valve core 10 further includes two first sealing rings 31. The first seal ring 31 may be an O-ring seal. Both first sealing rings 31 are sleeved on the second sleeve 251. The inner edge of the first seal ring 31 abuts against the outer peripheral surface of the second sleeve 251, and the outer edge of the first seal ring 31 abuts against the inner peripheral surface of the third pipe section 133. Two first sealing rings 31 are distributed on opposite sides of the strip groove 134. This prevents water in the third tube segment 133 from leaking out of the strip groove 134.

In one exemplary embodiment, as shown in fig. 7 and 22, two first annular grooves 254 are also provided on the second sleeve 251. The first annular groove 254 is disposed coaxially with the second sleeve 251. Two first seal rings 31 are partially embedded in the two first annular grooves 254, respectively.

Partial embedding of the first seal ring 31 into the first annular groove 254 can avoid axial movement of the first seal ring 31 in the second sleeve 251.

In one exemplary embodiment, as shown in fig. 7 and 10, the water diversion valve core 10 further includes a second seal ring 35. The second sealing ring 35 is sleeved on the connecting pipe 252 and is clamped between the connecting pipe 252 and the first sleeve 241. The second seal ring 35 is used to seal the gap between the first rotor 24 and the second rotor 25.

In an exemplary embodiment, as shown in fig. 22, a second annular groove 256 is also provided on the connection tube 252. The second annular groove 256 is concavely formed by the outer circumferential surface of the connection pipe 252. The second annular groove 256 is disposed coaxially with the connecting tube 252. The inner edge portion of the second seal ring 35 is embedded in the second annular groove 256.

Since the second seal ring 35 is partially embedded in the second annular groove 256, the second annular groove 256 defines the position of the second seal ring 35 such that the second seal ring 35 does not move during use.

In one exemplary embodiment, as shown in fig. 7 and 10, the water diversion valve core 10 further includes a third seal 32. The third seal 32 is sandwiched between the first rotor 24 and the rotor disc 23. The third seal 32 is disposed coaxially with the first sleeve 24.

In one exemplary embodiment, as shown in fig. 7, a third annular groove 246 is provided on the end of the first rotor 24 facing the turntable 23. The third annular groove 246 is recessed from the end face of the first rotor 24 toward the turntable 23. A third annular groove 246 is located at the outer edge of the end face. One end portion of the third seal ring 32 is embedded in the third annular groove 246.

Since the third seal ring 32 is partially embedded within the third annular groove 246, the third annular groove 246 defines the position of the third seal ring 32 such that the third seal ring 32 does not move during use.

In an exemplary embodiment, as shown in fig. 7, 10, 25, the rotating column 2 further includes a gasket 16. The gasket 16 is sandwiched between the stationary plate 15 and the base 14. The gasket 16 includes two seal rings 161. Two seal rings 161 may be connected together. One seal ring 161 surrounds the first through hole 142 of the base 14, and the other seal ring 161 surrounds the second through hole 143 of the base 14. The gasket 16 serves to seal the gap between the stationary plate 15 and the base 14, thereby preventing water from oozing out from the ends of the first and second through holes 142 and 143 near the stationary plate 15.

As shown in fig. 17, a mounting groove 141 is also provided at an end of the base 14 facing the stationary plate 15. The mounting groove 141 surrounds the first through hole 142 and the second through hole 143. The shape of the mounting groove 141 matches the shape of the gasket 16.
