[0075] A water outlet system according to embodiments of the present disclosure will now be described. The water outlet system can include a valve device. The water outlet system can also include a body. The body can be provided with a waterway structure. The valve device can be mounted to the body and in communication with the waterway structure. The waterway structure introduces hot water and cold water to the valve device and directs water outlet of the valve device to at least one water outlet mechanism. The water outlet mechanism can include, but is not limited to, a water outlet faucet, a shower head, a top spray, or a spray gun.

[0076] Please refer to Figures 1 to 3 、 Figures 5 to 12 、 Figure 16 and Figure 17 together, the valve device includes a valve core 10 and a valve body 20. The valve core 10 includes a housing mechanism 11 and a rotating mechanism 12. The housing mechanism 11 is provided with a first water inlet flow channel 100, a second water inlet flow channel 200, a first water outlet flow channel 301, and a second water outlet flow channel 302. One of the first water inlet flow channel 100 and the second water inlet flow channel 200 is arranged to introduce hot water into the valve core 10, and the other is arranged to introduce cold water into the valve core 10. In embodiments of the present disclosure, the first water inlet flow channel 100 introduces hot water into the valve core 10, and the second water inlet flow channel 200 introduces cold water into the valve core 10.

[0077] The rotating mechanism 12 includes a rotating assembly 121 and a pressure balance assembly 122. The rotating assembly 121 is at least partially accommodated in the housing mechanism 11. The rotating assembly 121 is provided with a mounting space 400. The rotating assembly 121 is provided with a first port 401 and a second port 402 in communication with the mounting space 400. The rotating assembly 121 is arranged to be rotatable about a first direction relative to the housing mechanism 11, to simultaneously communicate or disconnect with the first water inlet flow channel 100 and the second water inlet flow channel 200, and to communicate or separate the first port 401 from the first water outlet flow channel 301 and the second port 402 from the second water outlet flow channel 302. The first direction is parallel to the direction indicated by arrow X in Figure 2 .

[0078] The pressure balance assembly 122 is mounted in the mounting space 400, separates the first port 401 from the second port 402, and communicates between the first water inlet flow channel 100 and the first port 401 and between the second water inlet flow channel 200 and the second port 402. The pressure balance assembly 122 is arranged to adapt to the water pressure change of the water supplied to the first water inlet flow channel 100 and the second water inlet flow channel 200, and to adjust the flow area between the first water inlet flow channel 100 and the first port 401 and between the second water inlet flow channel 200 and the second port 402.

[0079] As Figure 7a and Figure 7bAs shown, the rotating assembly 121 is in its initial position. The rotating assembly 121 is disconnected from both the first water inlet channel 100 and the second water inlet channel 200 (×). Neither hot water nor cold water can enter the rotating assembly 121, and water flows out through the first and second water outlet channels 301 and 302. The valve core 10 is in a closed state. At this point, the first port 401 and the first water outlet channel 301, as well as the second port 402 and the second water outlet channel 302, can be connected or isolated.

[0080] like Figure 8a and Figure 8b As shown, the rotating assembly 121 rotates to the first position relative to the housing mechanism 11, and the rotating assembly 121 is connected to the first water inlet channel 100 and the second water inlet channel 200 at the same time, so that hot water and cold water enter the pressure balance assembly 122 at the same time, so that the pressure balance assembly 122 adapts to the water pressure changes of the water supplied to the first water inlet channel 100 and the second water inlet channel 200, and adjusts the flow area between the first water inlet channel 100 and the first port 401 and between the second water inlet channel 200 and the second port 402, thereby automatically adjusting the amount of hot water discharged from the first port 401 and the amount of cold water discharged from the second port 402, so that the outlet water temperature of the valve device fluctuates less, achieving a constant temperature effect. At this time, the first port 401 is separated from the first water outlet channel 301 by the blockage of the housing mechanism 11, and the second port 402 is connected to the second water outlet channel 302. Hot water is blocked and can only enter the first water outlet channel 301 in a small amount, while cold water can smoothly enter the second water outlet channel 302. In the pressure balancing assembly 122, a small amount of hot water is discharged, causing the hot water to be in a pressure-retaining state and the cold water to be in a pressure-releasing state, making the water pressure generated by the hot water greater than the water pressure generated by the cold water. The pressure balancing assembly 122 can reduce the flow area between the first water inlet channel 100 and the first port 401, while increasing the flow area between the second water inlet channel 200 and the second port 402, completely opening the area between the second water inlet channel 200 and the second port 402, and achieving the maximum flow rate of cold water outflow. This allows the water temperature to be adjusted at the rear end of the pressure balancing assembly 122, avoiding a low water flow rate when the water outlet is adjusted to cold water.

[0081] like Figure 9a and Figure 9bAs shown, the rotating assembly 121 continues to rotate relative to the housing mechanism 11 to the second position, the rotating assembly 121 is in communication with the first water inlet channel 100 and the second water inlet channel 200 at the same time, so that hot water and cold water enter the pressure balance assembly 122 at the same time. At this time, the first port 401 is in communication with the first water outlet channel 301, and the second port 402 is in communication with the second water outlet channel 302. Hot water can enter the first water outlet channel 301. Cold water can enter the second water outlet channel 302 and form warm water after mixing, so that the valve core 10 is in a warm water outlet state. In the pressure balance assembly 122, hot water and cold water are in a pressure relief state, so that the pressure balance assembly 122 adapts to the water pressure change of the water supplied to the first water inlet channel 100 and the second water inlet channel 200, adjusts the flow area between the first water inlet channel 100 and the first port 401 and between the second water inlet channel 200 and the second port 402, and then automatically adjusts the amount of hot water discharged by the first port 401 and the amount of cold water discharged by the second port 402, so that the water temperature fluctuation of the valve device is small, and the constant temperature effect is achieved.

[0082] As shown in Figure 10a and Figure 10b , the rotating assembly 121 continues to rotate relative to the housing mechanism 11 to the third position, the rotating assembly 121 is in communication with the first water inlet channel 100 and the second water inlet channel 200 at the same time, so that hot water and cold water enter the pressure balance assembly 122 at the same time, so that the pressure balance assembly 122 adapts to the water pressure change of the water supplied to the first water inlet channel 100 and the second water inlet channel 200, adjusts the flow area between the first water inlet channel 100 and the first port 401 and between the second water inlet channel 200 and the second port 402, and then automatically adjusts the amount of hot water discharged by the first port 401 and the amount of cold water discharged by the second port 402, so that the water temperature fluctuation of the valve device is small, and the constant temperature effect is achieved. At this time, the second port 402 is separated from the second water outlet channel 302 by plugging of the housing mechanism 11, and the first port 401 is in communication with the first water outlet channel 301. Cold water is blocked and can only enter the second water outlet channel 302 in a small amount, while hot water can smoothly enter the first water outlet channel 301. In the pressure balance assembly 122, a small amount of cold water is discharged, causing the cold water to be in a pressure holding state and the hot water to be in a pressure relief state, so that the water pressure formed by the cold water is greater than the water pressure formed by the hot water, the pressure balance assembly 122 can reduce the flow area between the second water inlet channel 200 and the second port 402, and increase the flow area between the first water inlet channel 100 and the first port 401, so that the first water inlet channel 100 and the first port 401 are completely open, realizing the maximum flow of the hot water outlet state. Thus, the water temperature is adjusted after the pressure balance assembly 122, avoiding the small flow of the outlet water when the outlet water is adjusted to hot water.

[0083] The rotating assembly 121 can continue to rotate relative to the housing mechanism 11 to the initial position, or can rotate reversely to the initial position.

[0084] By implementing the embodiments of the present disclosure, the following beneficial effects can be achieved:

[0085] The valve core 10 can be applied to the valve device and the water outlet system. In addition to the functions of controlling the water outlet flow, the water temperature and keeping the water temperature constant, the valve core 10 can also prevent the hot and cold water from intermingling and has the temperature adjustment function. Specifically, the valve core 10 includes the housing mechanism 11 provided with the first water inlet channel 100, the second water inlet channel 200, the first water outlet channel 301 and the second water outlet channel 302, and the rotating mechanism 12 including the rotating assembly 121 and the pressure balance assembly 122. The rotating assembly 121 is provided with the mounting space 400, and the pressure balance assembly 122 is mounted in the mounting space 400. The rotating assembly 121 is provided with the first port 401 and the second port 402 in communication with the mounting space 400. One of the first water inlet channel 100 and the second water inlet channel 200 is arranged to introduce hot water into the valve core 10, and the other is arranged to introduce cold water into the valve core 10.

[0086] During the rotation of the rotating assembly 121 relative to the housing mechanism 11, the rotating assembly 121 can be in communication or disconnected with the first water inlet channel 100 and the second water inlet channel 200 at the same time, so that the different types of water (hot water and cold water) are controlled at the front end of the pressure balance assembly 122, and a one-way valve is not needed to prevent the hot and cold water from intermingling.

[0087] During the rotation of the rotating assembly 121 relative to the housing mechanism 11, the first port 401 can be in communication or disconnected with the first water outlet channel 301, and the second port 402 can be in communication or disconnected with the second water outlet channel 302, so as to adjust the water temperature. Moreover, the water temperature adjustment position is at the rear end of the pressure balance assembly 122, which can avoid the small water outlet flow when the water outlet is adjusted to cold water or hot water.

[0088] In the exemplary embodiments, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 11 and Figure 12 , the rotating assembly 121 includes the rotating piece 1211. The housing mechanism 11 is provided with the connecting hole 500, and the rotating piece 1211 is partially matched with the connecting hole 500 and is rotatably connected with the housing mechanism 11 through the connecting hole 500.

[0089] ​Thus, the connection hole 500 can increase the connection area between the rotating member 1211 and the housing mechanism 11, improve the stability of the rotating member 1211 relative to the housing mechanism 11, and enable the housing mechanism 11 to limit the movement of the rotating member 1211 along the radial direction of the rotating member 1211, thereby ensuring the accuracy of the rotating positions of the first port 401, the second port 402, and the pressure balance assembly 122, and improving the accuracy of the pressure balance assembly 122 in automatically adjusting the water flow rates of the first port 401 and the second port 402.

[0090] In the embodiments of the present disclosure, the rotating member 1211 is partially exposed to the housing mechanism 11 from the connection hole 500, so as to be driven to rotate relative to the housing mechanism 11. The circumferential outer wall of the part of the rotating member 1211 exposed to the housing mechanism 11 can be provided with a rotation-stopping plane 12111, so as to facilitate the rotation-stopping connection between the rotating member 1211 and the driving structure. In addition, the rotating member 1211 and the driving structure can also be connected by a threaded connection, a clamping connection, a plug-in connection, or a welding connection. The rotating member 1211 has a stepped shaft section, which can form a limiting connection with the housing mechanism 11, so that part of the stepped shaft section is exposed to the housing mechanism 11 from the connection hole 500, and another part of the stepped shaft section is limited by the housing mechanism 11, so as to avoid the separation of the rotating member 1211 from the housing mechanism 11 through the connection hole 500. A first sealing ring 30 is further arranged between the stepped shaft section and the hole wall of the connection hole 500 formed by the housing mechanism 11, so as to avoid the overflow of different types of water (hot water and cold water) between the stepped shaft section and the hole wall. At least one of the stepped shaft section and the housing mechanism 11 is provided with a mounting groove for mounting the first sealing ring 30, so as to ensure the position accuracy of the first sealing ring 30. The first sealing ring 30 forms a radial seal between the stepped shaft section and the hole wall, reduces the axial end face seal of the valve core 10, avoids the rotation of the rotating mechanism 12 relative to the housing mechanism 11 due to the excessive extrusion deformation of the first sealing ring 30 caused by the axial end face seal, and avoids the poor sealing performance and water leakage caused by the insufficient extrusion deformation of the first sealing ring 30 caused by the axial end face seal, thereby increasing the failure rate of the valve core 10.

[0091] In the exemplary embodiments, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 11 , Figure 12 , Figure 16 and Figure 17The rotating member 1211 is provided with a first limiting portion 12112, and the housing mechanism 11 is provided with a second limiting portion 111. The first limiting portion 12112 and the second limiting portion 111 at least partially overlap in the circumferential direction of the first direction. During rotation of the rotating member 1211 relative to the housing mechanism 11, the first limiting portion 12112 can abut against the second limiting portion 111 to limit the angle range of rotation of the rotating member 1211 relative to the housing mechanism 11. The first limiting portion 12112 and the second limiting portion 111 are both protruding structures and extend in the first direction. In the embodiment of the present disclosure, the number of first limiting portions 12112 is two and they are arranged at intervals in the circumferential direction of the first direction. The number of second limiting portions 111 is two and they are arranged at intervals in the circumferential direction of the first direction, so that during the limitation of the angle range of rotation of the rotating member 1211 relative to the housing mechanism 11, the two first limiting portions 12112 and the two second limiting portions 111 abut against each other one by one, thereby ensuring the stability of the limitation of the angle range of rotation of the rotating member 1211 relative to the housing mechanism 11.

[0092] The rotating member 1211 is partially sleeved with a limiting ring 1213 outside the housing mechanism 11, and the first limiting portion 12112 is arranged on the side of the limiting ring 1213 facing the housing mechanism 11. The second limiting portion 111 is arranged on the side of the housing mechanism 11 facing the limiting ring 1213. The limiting ring 1213 is rotationally connected with the rotating member 1211. For example, the circumferential outer side of the rotating member 1211 has an outer straight tooth surface 12113 extending in the first direction, and the inner side of the limiting ring 1213 has an inner straight tooth surface 12131 extending in the first direction. The outer straight tooth surface 12113 and the inner straight tooth surface 12131 are inserted in the first direction, so that the limiting ring 1213 is rotationally connected with the rotating member 1211. In addition, the limiting ring 1213 can be detachably connected with the rotating member 1211. After the relative position of the rotating member 1211 and the housing mechanism 11 is adjusted, the limiting ring 1213 is rotationally connected with the rotating member 1211 to limit the angle range of rotation of the rotating member 1211 relative to the housing mechanism 11.

[0093] In the exemplary embodiments, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 11 , the mounting space 400 and the rotating member 1211 both extend in the first direction, and the axis of the mounting space 400 is collinear with the axis of the rotating member 1211. One end of the mounting space 400 is exposed to the rotating member 1211 and communicates with the first port 401. In this way, the pressure balance assembly 122 and the rotating mechanism 12 are coaxially arranged, which facilitates the waterway design of the first water inlet flow channel 100, the second water inlet flow channel 200, the first water outlet flow channel 301 and the second water outlet flow channel 302 communicating with the pressure balance assembly 122.

[0094] In the exemplary embodiments, please refer toFigure 2 、 Figure 3 、 Figure 5 and Figure 6 The pressure balance assembly 122 comprises a valve sleeve 1221 and an inner core 1222.

[0095] The valve sleeve 1221 is installed in the installation space 400. A sealing structure can be further arranged between the circumferential outer side of the valve sleeve 1221 and the rotating member 1211, which on one hand ensures the sealing between the valve sleeve 1221 and the rotating member 1211, and on the other hand, the valve sleeve 1221 and the rotating member 1211 also make the sealing structure elastically deform, thereby improving the connection stability between the valve sleeve 1221 and the rotating member 1211.

[0096] The valve sleeve 1221 is circumferentially provided with a first adjusting port 403 and a second adjusting port 404, and the two ends of the valve sleeve 1221 in the first direction are respectively communicated with the first port 401 and the second port 402.

[0097] During the rotation of the rotating assembly 121 relative to the housing mechanism 11, the first adjusting port 403 and the second adjusting port 404 can be respectively communicated with or disconnected from the first water inlet flow channel 100 and the second water inlet flow channel 200.

[0098] The inner core 1222 can move relative to the valve sleeve 1221 in the first direction, adapt to the water pressure change of the water supplied to the first water inlet flow channel 100 and the second water inlet flow channel 200, and adjust the flow area between the first adjusting port 403 and the first port 401 and between the second adjusting port 404 and the second port 402. The inner core 1222 comprises a pipe body 12221 and a partition wall 12222 arranged on the pipe body 12221, and the partition wall 12222 equally divides the pipe body 12221 in the first direction to form a first cavity 405 and a second cavity 406 on both sides of the partition wall 12222. The first cavity 405 is communicated with the first port 401. The second cavity 406 is communicated with the second port 402. The pipe body 12221 is provided with a first flow groove 407 and a second flow groove 408 near the partition wall 12222, which are communicated with the first cavity 405 and the second cavity 406, respectively. During the movement of the inner core 1222 relative to the valve sleeve 1221 in the first direction, the flow area between the first flow groove 407 and the first adjusting port 403 and between the second flow groove 408 and the second adjusting port 404 can be changed, thereby adjusting the flow of water into the first cavity 405 and the second cavity 406.

[0099] In the exemplary embodiments, please refer to Figure 2 、 Figures 4 to 6 、 Figure 7a 、 Figure 8a 、 Figure 9a 、 Figure 10a and Figures 13 to 15The housing mechanism 11 comprises a housing assembly 112 and a fixed valve plate 113. The fixed valve plate 113 is rotationally connected to the housing assembly 112. In this way, the fixed valve plate 113 is prevented from rotating during rotation of the rotating mechanism 12 relative to the housing mechanism 11.

[0100] The first water inlet channel 100 and the second water inlet channel 200 respectively pass through the housing assembly 112 and the fixed valve plate 113 in sequence. The first water outlet channel 301, the second water outlet channel 302 and the connecting hole 500 are located on the housing assembly 112. The rotating member 1211 is partially accommodated in the housing assembly 112 and is arranged in the first direction away from the fixed valve plate 113. The housing assembly 112 and the fixed valve plate 113 can be an integral structure or a split structure.

[0101] The rotating assembly 121 further comprises a movable valve plate 1214 rotationally connected to one side of the rotating member 1211 facing the fixed valve plate 113 and abutting against the fixed valve plate 113. In this way, the movable valve plate 1214 is prevented from rotating relative to the rotating member 1211 during rotation of the rotating mechanism 12 relative to the housing mechanism 11. In the embodiment of the present disclosure, the fixed valve plate 113 and the movable valve plate 1214 are both ceramic plates, which can improve the corrosion resistance and structural stability of the fixed valve plate 113 and the movable valve plate 1214 and prevent them from being affected by temperature changes, thereby ensuring the precision of the cooperation between the fixed valve plate 113 and the movable valve plate 1214. The movable valve plate 1214 and the rotating member 1211 can be an integral structure or a split structure.

[0102] The movable valve plate 1214 is provided with a first flow port 801 and a second flow port 802 in communication with the mounting space 400. The first port 401 is arranged on the movable valve plate 1214. During rotation of the rotating assembly 121 relative to the housing mechanism 11, the movable valve plate 1214 can slide relative to the fixed valve plate 113 and communicate or disconnect the first flow port 801 and the second flow port 802 with the first water inlet channel 100 and the second water inlet channel 200, respectively, and communicate or separate the first port 401 from the first water outlet channel 301.

[0103] In the embodiment of the present disclosure, the flow area of the first flow port 801 on the side facing the first water inlet channel 100 is smaller than the flow area of the first flow port 801 on the side facing the mounting space 400, and the flow area of the second flow port 802 on the side facing the second water inlet channel 200 is smaller than the flow area of the second flow port 802 on the side facing the mounting space 400. In this way, the precision of the movable valve plate 1214 and the fixed valve plate 113 in controlling different types of water (hot water and cold water) into the movable valve plate 1214 is higher, and the different types of water (hot water and cold water) have a larger flow area to flow to the side of the mounting space 400.

[0104] In the exemplary embodiments, please refer toFigure 4 、 Figure 6 and Figure 13 , the shell assembly 112 and the fixed valve sheet 113 can be detachably connected. The shell assembly 112 is provided with a plurality of first plug-in parts 114. The first plug-in parts 114 extend along a first direction, and the fixed valve sheet 113 is provided with a plurality of second plug-in parts 115 extending along the first direction, and the plurality of first plug-in parts 114 and the plurality of second plug-in parts 115 are one-to-one plug-in. In this way, the maintenance and replacement of the fixed valve sheet 113 can be facilitated. And the plurality of first plug-in parts 114 and the plurality of second plug-in parts 115 cooperate to make the shell assembly 112 and the fixed valve sheet 113 rotationally connected. The number of the first plug-in parts 114 and the second plug-in parts 115 is three, and they are distributed in a triangular shape, which further improves the stability of the rotationally connected shell assembly 112 and the fixed valve sheet 113. The first plug-in part 114 is arranged on the side of the shell assembly 112 facing the fixed valve sheet 113 along the first direction, and the second plug-in part 115 is arranged on the side of the fixed valve sheet 113 facing the shell assembly 112 along the first direction. One of the first plug-in part 114 and the second plug-in part 115 is a protruding structure, and the other has an inner wall forming a groove structure. The circumferential outer wall of the protruding structure has a supporting protrusion 1141 which can be supported on the inner wall, reducing the connection area between the first plug-in part 114 and the second plug-in part 115, facilitating the disassembly of the shell assembly 112 and the fixed valve sheet 113. Moreover, the arrangement of the supporting protrusion 1141 can also improve the elastic deformation ability of the protruding structure, and the elastic deformation can facilitate the plug-in cooperation of the first plug-in part 114 and the second plug-in part 115, reducing the assembly precision of the first plug-in part 114 and the second plug-in part 115. The side of the protruding structure facing the groove structure and the side of the inner wall facing the protruding structure can be respectively provided or both provided with a guide surface to facilitate the plug-in cooperation of the first plug-in part 114 and the second plug-in part 115. In the embodiment of the present disclosure, the first plug-in part 114 is a protruding structure. The second plug-in part 115 has a groove structure.

[0105] In an exemplary embodiment, please combine Figures 4 to 6 , the fixed valve sheet 113 can move relative to the first plug-in part 114 along the first direction. The first water inlet flow channel 100, the second water inlet flow channel 200 and the first water outlet flow channel 301 form a first water inlet through hole 101, a second water inlet through hole 201 and a first water outlet through hole 701 on the side of the shell assembly 112 facing the fixed valve sheet 113, and the first water inlet flow channel 100, the second water inlet flow channel 200 and the first water outlet flow channel 301 form a first water inlet outlet 102, a second water inlet outlet 202 and a second water outlet through hole 702 on the fixed valve sheet 113 respectively.

[0106] The valve core 10 further comprises a first elastic sealing member 13 clamped between the housing assembly 112 and the fixed valve plate 113 in the first direction. The first elastic sealing member 13 encloses a first through hole 901, a second through hole 902 and a third through hole 903. The first through hole 901 is communicated between the first water inlet port 101 and the first water inlet outlet 102. The second through hole 902 is communicated between the second water inlet port 201 and the second water inlet outlet 202. The third through hole 903 is communicated between the first water outlet port 701 and the second water outlet port 702.

[0107] Thus, the first elastic sealing member 13 can ensure the sealing between the first water inlet port 101 and the first water inlet outlet 102, between the second water inlet port 201 and the second water inlet outlet 202, and between the first water outlet port 701 and the second water outlet port 702, so as to avoid the overflow of different types of water (hot water and cold water) from between the housing assembly 112 and the fixed valve plate 113. The elastic deformation performance of the first elastic sealing member 13 can further improve the sealing between the housing assembly 112 and the fixed valve plate 113, and can elastically abut the fixed valve plate 113 against the movable valve plate 1214, so as to ensure the cooperation precision between the fixed valve plate 113 and the movable valve plate 1214, and can automatically adjust the position of the fixed valve plate 113 relative to the first plug-in part 114 according to the abutting force between the fixed valve plate 113 and the movable valve plate 1214, so as to reduce the rotation resistance of the movable valve plate 1214 relative to the fixed valve plate 113 in the rotation process.

[0108] In the embodiments of the present disclosure, at least one of the housing assembly 112 and the fixed valve plate 113 is further provided with a mounting groove for mounting the first elastic sealing member 13, so as to ensure the position precision of the first elastic sealing member 13.

[0109] In the exemplary embodiments, please refer to Figure 4 , Figure 11 , Figure 14 and Figure 15The rotating member 1211 and the movable valve plate 1214 are detachably connected. The rotating member 1211 is provided with a plurality of third insertion portions 1212. The third insertion portions 1212 extend along the first direction, and the movable valve plate 1214 is provided with a plurality of fourth insertion portions 12141 extending along the first direction, and the plurality of third insertion portions 1212 and the plurality of fourth insertion portions 12141 are one-to-one correspondingly inserted. In this way, the maintenance and replacement of the movable valve plate 1214 can be facilitated. And the cooperation of the plurality of third insertion portions 1212 and the plurality of fourth insertion portions 12141 can make the rotating member 1211 and the movable valve plate 1214 rotationally connected. The number of the first insertion portions 114 and the second insertion portions 115 is three, and they are respectively arranged at intervals around the first direction. Further improve the stability of the rotationally connected rotating member 1211 and the movable valve plate 1214. In addition, in some embodiments, the number of the first insertion portions 114 and the second insertion portions 115 can also be more than three.

[0110] The third insertion portion 1212 is arranged on the side of the rotating member 1211 facing the movable valve plate 1214 along the first direction, and the fourth insertion portion 12141 is arranged on the side of the movable valve plate 1214 facing the rotating member 1211 along the first direction. One of the third insertion portion 1212 and the fourth insertion portion 12141 is a protruding structure, and the other has a slot wall forming a notch slot. The protruding structure is inserted into the notch slot and abuts against the slot wall. In the embodiment of the present disclosure, the third insertion portion 1212 is a protruding structure. The fourth insertion portion 12141 has a notch slot.

[0111] In the exemplary embodiments, please combine Figures 4 to 6 , Figure 11 and Figure 14 , the movable valve plate 1214 can move relative to the third insertion portion 1212 along the first direction. The rotating member 1211 is provided with a first flow space 409 and a second flow space 410, and the first flow space 409 and the second flow space 410 are respectively communicated with the mounting space 400. The second flow space 410 is communicated with the second flow port 802.

[0112] The valve core 10 further comprises a second elastic sealing member 14 clamped between the rotating member 1211 and the movable valve plate 1214 along the first direction, and the second elastic sealing member 14 encloses a fourth through hole 904 communicating between the first flow space 409 and the first flow port 801. Thus, the setting of the second elastic sealing member 14 can ensure the sealing between the first flow space 409 and the first flow port 801, and avoid the overflow of different types of water (hot water and cold water) from between the rotating member 1211 and the movable valve plate 1214. By using the elastic deformation performance of the second elastic sealing member 14, the sealing between the rotating member 1211 and the movable valve plate 1214 can be further improved, and the movable valve plate 1214 is elastically abutted against the fixed valve plate 113, so as to ensure the cooperation precision between the fixed valve plate 113 and the movable valve plate 1214, and automatically adjust the position of the movable valve plate 1214 relative to the third plug-in part 1212 according to the abutting force between the fixed valve plate 113 and the movable valve plate 1214, so as to reduce the rotation resistance of the movable valve plate 1214 relative to the fixed valve plate 113 in the rotation process.

[0113] In the embodiments of the present disclosure, at least one of the rotating member 1211 and the movable valve plate 1214 is further provided with a mounting groove for mounting the second elastic sealing member 14, so as to ensure the position precision of the second elastic sealing member 14.

[0114] In the example embodiments, please refer to Figures 4 to 6 and Figure 14 , the side of the movable valve plate 1214 facing the mounting space 400 is provided with a positioning groove 600, the pressure balance assembly 122 penetrates the fourth through hole 904 and is plugged into the positioning groove 600, and is in sealing connection with the movable valve plate 1214, and the first port 401 penetrates the groove bottom of the positioning groove 600.

[0115] Since the type of water (hot water or cold water) flowing between the first flow space 409 and the first flow port 801 is the same as the type of water discharged from the first port 401, even if there is mutual leakage, it will not affect the water temperature, and thus the setting of the second elastic sealing member 14 can ensure that water does not overflow from the outside of the space enclosed by the second elastic sealing member 14. The sealing connection between the pressure balance assembly 122 and the movable valve plate 1214 can avoid the mutual leakage of water between the first flow port 801 and the first port 401, and improve the connection stability between the pressure balance assembly 122 and the movable valve plate 1214.

[0116] The pressure balance assembly 122 is limitingly connected between the rotating member 1211 and the movable valve plate 1214 along the first direction, so as to ensure the position stability of the pressure balance assembly 122.

[0117] In the example embodiments, please refer to Figure 1 , Figure 2 ,Figure 5 and Figure 6 The shell assembly 112 includes an upper shell 1121 and a lower shell 1122 that are detachably connected. The connecting hole 500 is arranged on the upper shell 1121, and the fixed valve plate 113 is rotationally connected to the lower shell 1122. The upper shell 1121 and the lower shell 1122 are arranged in sequence along the first direction, the upper shell 1121 abuts against the side of the rotating member 1211 away from the movable valve plate 1214, and the lower shell 1122 abuts against the side of the fixed valve plate 113 away from the movable valve plate 1214. In this way, the detachable arrangement of the upper shell 1121 and the lower shell 1122 facilitates the installation of the rotating mechanism 12, the first elastic sealing member 13, the fixed valve plate 113, and the second elastic sealing member 14, and clamps the rotating mechanism 12, the first elastic sealing member 13, the fixed valve plate 113, and the second elastic sealing member 14 along the first direction, thereby ensuring that the fixed valve plate 113 and the movable valve plate 1214 can elastically abut against each other, improving the fitting accuracy, and ensuring the position accuracy of the pressure balance assembly 122. The upper shell 1121 and the lower shell 1122 are rotationally connected, so as to avoid the rotation of the upper shell 1121 relative to the lower shell 1122 during the rotation of the rotating mechanism 12 relative to the shell mechanism 11. In addition, the upper shell 1121 and the lower shell 1122 can be detachably connected by means of clamping, insertion, or the like. In the embodiment of the present disclosure, the side of the upper shell 1121 facing the lower shell 1122 is provided with rotation-stopping grooves 1000 and clamping arms 11211. The number of the rotation-stopping grooves 1000 and the clamping arms 11211 is both multiple and arranged around the first direction. The clamping arms 11211 are provided with clamping grooves. The side of the lower shell 1122 facing the upper shell 1121 is provided with rotation-stopping protrusions 11221 and clamping protrusions 11222. The number of the rotation-stopping protrusions 11221 is consistent with the number of the rotation-stopping grooves 1000 and is one-to-one correspondingly inserted. The number of the clamping protrusions 11222 is consistent with the number of the clamping arms 11211 and is one-to-one correspondingly clamped in the corresponding clamping grooves.

[0118] In the example embodiment, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 7a , Figure 8a , Figure 9a , Figure 10a , Figure 16 and Figure 17 The second water outlet flow channel 302 penetrates the circumferential outer wall of the shell mechanism 11, and the first water inlet flow channel 100, the second water inlet flow channel 200, and the first water outlet flow channel 301 form the first water inlet 103, the second water inlet 203, and the first water outlet 703 on the circumferential outer wall of the shell mechanism 11, respectively.

[0119] The circumferential outer wall of the valve body 20 is provided with a first liquid inlet flow channel 1101, a second liquid inlet flow channel 1102 and a liquid outlet flow channel 1103. The valve body 20 is sleeved on the valve core 10 and is rotationally connected with the valve core 10. The first liquid inlet flow channel 1101 and the second liquid inlet flow channel 1102 are respectively communicated with the first water inlet flow channel 100 and the second water inlet flow channel 200 one by one. The liquid outlet flow channel 1103 is communicated with the first water outlet 703. The mixed liquid flow channel 1104 is formed between the valve body 20 and the valve core 10, and the mixed liquid flow channel 1104 is communicated between the second water outlet flow channel 302 and the liquid outlet flow channel 1103. In this way, different types of water (hot water and cold water) can enter the valve core 10 from the radial direction of the valve core 10 and flow out from the radial direction of the valve core 10, forming a side-in side-out valve core 10 structure, thereby avoiding the different types of water (hot water and cold water) from entering and flowing out of the valve core 10 from the end of the valve core 10, and achieving a certain flow requirement, which causes the valve core 10 to have a larger radial dimension. In order to match the structure of the cold and hot water entering and flowing out of the end of the valve core 10, the valve body 20 needs to be provided with a corresponding water channel structure inside, which increases the use of the material of the valve body 20, makes the valve body 20 large in size and heavy in weight, and increases the cost. In the embodiment of the present disclosure, the side-in side-out valve core 10 structure can avoid the valve body 20 from being additionally provided with other water channel structures on the basis of the original water channel structure, so that the valve body 20 is smaller in size, lighter in weight and lower in cost. A part of the circumferential outer side of the shell mechanism 11 is matched with the valve body 20 to ensure the sealing property of the valve body 20, and a plurality of second sealing rings 40 can be arranged between the shell mechanism 11 and the valve body 20 to further improve the sealing property between the shell mechanism 11 and the valve body 20. Another part of the circumferential outer side of the shell mechanism 11 is spaced apart from the valve body 20 to form the mixed liquid flow channel 1104. When the valve core 10 is in a cold water outlet state, cold water can enter the liquid outlet flow channel 1103 through the mixed liquid flow channel 1104. When the valve core 10 is in a warm water outlet state, hot water and cold water can simultaneously enter the mixed liquid flow channel 1104 and then enter the liquid outlet flow channel 1103 through the mixed liquid flow channel 1104. When the valve core 10 is in a hot water outlet state, hot water can enter the liquid outlet flow channel 1103 through the mixed liquid flow channel 1104.

[0120] In the embodiment of the present disclosure, please refer to Figure 1 and Figure 16 , the valve core 10 and the valve body 20 are respectively provided with a first rotation stopping part 15 and a second rotation stopping part 21. One of the first rotation stopping part 15 and the second rotation stopping part 21 is a protruding structure, and the other has a groove structure. The protruding structure is accommodated in the groove structure to rotationally connect the valve core 10 and the valve body 20.

[0121] In the exemplary embodiment, please refer to Figure 16 and Figure 17 , the number of the liquid outlet flow channels 1103 is multiple, and each can be communicated with a plurality of water outlet mechanisms.

[0122] The shell mechanism 11 is provided with a drainage space 1200, and the drainage space 1200 is provided with a drainage pipe 50 capable of connecting the plurality of liquid outlet channels 1103. In this way, the mixed liquid channel 1104 can be connected to one of the liquid outlet channels 1103, reducing the design difficulty of the mixed liquid channel 1104 and ensuring that a larger part of the axial outer side of the shell mechanism 11 matches the valve body 20, thereby improving the stability of the connection.

[0123] In the embodiments of the present disclosure, the number of liquid outlet channels 1103 is two, and the liquid outlet channels 1103 are arranged on both sides of the valve core 10 along the second direction. The drainage pipe 50 is a straight pipe and can be sequentially inserted into the drainage space 1200 and the valve body 20 along the second direction. The liquid outlet channel 1103 and the drainage pipe 50 are arranged in the same direction, which facilitates the disassembly of the drainage pipe 50 and the disassembly of the valve core 10 and the valve body 20. In addition, the connection position of the mixed liquid channel 1104 and one of the liquid outlet channels 1103 is higher than the connection position of the liquid outlet channel 1103 and the drainage pipe 50, and the liquid outlet channel 1103 can be connected to a water outlet mechanism (for example, a bathtub water outlet nozzle) with a lower position, and the other liquid outlet channel 1103 can be connected to a water outlet mechanism (for example, a top spray) with a higher position. For example, the bathtub water outlet nozzle is usually provided with a pull valve, which can block the water outlet of the bathtub water outlet nozzle. When the pull valve is opened, due to the height difference between the above two connection positions, water flows out of the bathtub water outlet nozzle by gravity, and does not leak from the top spray; when the pull valve is closed, water cannot flow out of the bathtub water outlet nozzle, but flows out of the top spray, thereby realizing the switching of the waterway.
