[0029] The disclosed embodiments provide a valve core, a valve device, and a water outlet system. The water outlet system can be installed in various environments such as companies, schools, homes, and factories to achieve cleaning of items to be cleaned and body parts, thereby improving people's quality of life and health.

[0030] The water outlet system provided by the embodiment of the present disclosure is now described. The water outlet system may include a valve device. The water outlet system may also include a body. The body may be provided with a waterway structure, and the valve device may be installed on the body and communicated with the waterway structure. The waterway structure introduces hot water and cold water into the valve device, and guides the water outlet of the valve device to at least one water outlet mechanism. The water outlet mechanism may include but is not limited to a water outlet faucet, a shower, a top spray or a spray gun.

[0031] Please combine Figures 1 to 3 , Figures 5 to 10b , Fig.16 and Fig.17 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 hot water flow channel 100, a cold water flow channel 200 and a water outlet 300.

[0032] The rotating mechanism 12 includes a rotating assembly 121 and a pressure balancing assembly 122. The rotating assembly 121 is at least partially accommodated in the housing mechanism 11. The rotating assembly 121 is provided with an installation space 400, which penetrates the rotating assembly 121 and forms a first port 401 and a second port 402 on opposite sides of the rotating assembly 121. The rotating assembly 121 is configured to be able to rotate relative to the housing mechanism 11 around a first direction, to be connected or disconnected with the hot water flow channel 100 and the cold water flow channel 200 at the same time, and to connect or disconnect at least one of the first port 401 and the second port 402 with the water outlet 300. The first direction is parallel to Figure 2 The arrow X in the middle points to the direction.

[0033] The pressure balancing component 122 is installed in the installation space 400 through at least one of the first port 401 and the second port 402, separating the first port 401 from the second port 402, and connecting between the hot water flow channel 100 and the first port 401 and between the cold water flow channel 200 and the second port 402. The pressure balancing component 122 is configured to adapt to changes in water pressure supplied to the hot water flow channel 100 and the cold water flow channel 200, and adjust the flow area between the hot water flow channel 100 and the first port 401 and between the cold water flow channel 200 and the second port 402.

[0034] like Figure 7a and Figure 7b As shown, the rotating assembly 121 is in the initial position. The rotating assembly 121 is disconnected from the hot water flow channel 100 and the cold water flow channel 200 at the same time (×), and hot water and cold water cannot enter the rotating assembly 121, and water flows out from the water outlet 300, and the valve core 10 is in the water outlet closed state. At this time, the first port 401 and the second port 402 can be connected to the water outlet 300, or can be separated.

[0035] like Figure 8a and Figure 8b As shown, the rotating assembly 121 rotates to the first position relative to the shell mechanism 11, and the rotating assembly 121 is connected to the hot water flow channel 100 and the cold water flow 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 hot water flow channel 100 and the cold water flow channel 200, adjusts the flow area between the hot water flow channel 100 and the first port 401 and between the cold water flow channel 200 and the second port 402, and then automatically adjusts 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 water outlet 300 by the blocking of the shell mechanism 11, and the second port 402 is connected to the water outlet 300. The hot water is blocked and can only enter the water outlet 300 in a small amount, while the cold water can enter the water outlet 300 smoothly. In the pressure balance component 122, a small amount of hot water is discharged, causing the hot water to be in a pressure-holding state and the cold water to be in a pressure-releasing state, so that the water pressure formed by the hot water is greater than the water pressure formed by the cold water. The pressure balance component 122 can reduce the flow area between the hot water flow channel 100 and the first port 401, and increase the flow area between the cold water flow channel 200 and the second port 402, and completely open the cold water flow channel 200 and the second port 402 to achieve the maximum flow rate of cold water outflow. In this way, the water temperature can be adjusted at the rear end of the pressure balance component 122 to avoid a small water outflow when the outflow is adjusted to cold water.

[0036] like Figure 9a and Figure 9b As shown, the rotating assembly 121 continues to rotate to the second position relative to the housing mechanism 11, and the rotating assembly 121 is connected to the hot water flow channel 100 and the cold water flow 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 and the second port 402 are both connected to the water outlet 300. Hot water and cold water can both enter the water outlet 300, 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, both hot water and cold water are in a pressure relief state, so that the pressure balance assembly 122 adapts to the water pressure changes of the water supplied to the hot water flow channel 100 and the cold water flow channel 200, adjusts the flow area between the hot water flow channel 100 and the first port 401 and between the cold water flow channel 200 and the second port 402, and then automatically adjusts 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.

[0037] like Fig.10a and Fig.10bAs shown, the rotating assembly 121 continues to rotate to the third position relative to the shell mechanism 11, and the rotating assembly 121 is connected to the hot water flow channel 100 and the cold water flow 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 hot water flow channel 100 and the cold water flow channel 200, adjusts the flow area between the hot water flow channel 100 and the first port 401 and between the cold water flow channel 200 and the second port 402, and then automatically adjusts 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 second port 402 is separated from the water outlet 300 by the blocking of the shell mechanism 11, and the first port 401 is connected to the water outlet 300. The cold water is blocked and can only enter the water outlet 300 in a small amount, while the hot water can enter the water outlet 300 smoothly. In the pressure balance component 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-releasing 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 component 122 can reduce the flow area between the cold water channel 200 and the second port 402, and increase the flow area between the hot water channel 100 and the first port 401, and completely open the hot water channel 100 and the first port 401 to achieve the maximum flow rate of hot water outflow. In this way, the water temperature can be adjusted at the rear end of the pressure balance component 122 to avoid a small water flow rate when the water is adjusted to hot water.

[0038] The rotating assembly 121 can continue to rotate relative to the housing mechanism 11 to the initial position, or can rotate in the opposite direction to the initial position.

[0039] In the disclosed embodiment, there are two water outlets 300, which correspond one-to-one to the first port 401 and the second port 402, thereby reducing the angle range of rotation of the rotating component 121 relative to the shell mechanism 11 when the valve core 10 switches the water outlet state (water outlet closed state, cold water outlet state, warm water outlet state and hot water outlet state), so that the water outlet state switching is faster and more sensitive.

[0040] It can be understood that in other embodiments, the number of the water outlet 300 can also be one.

[0041] Implementing the embodiments of the present disclosure will have the following beneficial effects: The valve core 10 of the above scheme is applied to the valve device and the water outlet system. In addition to being able to control the water flow rate, water temperature and the efficiency of maintaining a constant water temperature, it can also facilitate the disassembly and assembly of the pressure balance component 122. Specifically, the valve core 10 includes a housing mechanism 11 provided with a hot water flow channel 100, a cold water flow channel 200 and a water outlet 300, and a rotating mechanism 12 including a rotating component 121 and a pressure balance component 122. The rotating component 121 is provided with an installation space 400 that penetrates the rotating component 121. The pressure balance component 122 is installed in the installation space 400 through one of the first port 401 and the second port 402 formed in the rotating component 121 in the installation space 400. In this way, the disassembly and assembly of the pressure balance component 122 can be facilitated, so that the formation position of the installation space 400 is set as an integrated structure, reducing the assembly cost, and can also improve the structural stability of the installation position of the pressure balance component 122, ensuring the working stability of the pressure balance component 122.

[0042] During the rotation of the rotating component 121 relative to the shell mechanism 11, it can be connected or disconnected with the hot water flow channel 100 and the cold water flow channel 200 at the same time, so that the hot water and cold water can be controlled at the front end of the pressure balance component 122, without the need to set up a one-way valve to prevent the mutual flow of hot and cold water, and to avoid adjusting the water temperature at the front end of the pressure balance component 122.

[0043] During the rotation of the rotating component 121 relative to the shell mechanism 11, at least one of the first port 401 and the second port 402 can be connected to or separated from the water outlet 300, so that the water temperature can be adjusted at the rear end of the pressure balance component 122 to avoid a small water flow rate when the water outlet is adjusted to cold water or hot water.

[0044] In the exemplary embodiment, please combine Figure 2 , Figure 5 , Figure 6 , Fig.11 and Fig.15 The rotating assembly 121 includes a rotating member 1211 and a valve seat 1212. The housing mechanism 11 is provided with a connecting hole 500, and the rotating member 1211 partially matches the connecting hole 500 and is rotatably connected to the housing mechanism 11 through the connecting hole 500. The installation space 400 is provided on the valve seat 1212, and the valve seat 1212 is non-rotatably connected to the rotating member 1211.

[0045] In this way, by setting the connecting hole 500, the connecting surface area between the rotating member 1211 and the shell mechanism 11 can be increased, the stability of the rotation of the rotating member 1211 relative to the shell mechanism 11 can be improved, and the shell mechanism 11 can limit the radial movement of the rotating member 1211 along the rotating member 1211, thereby ensuring the accuracy of the rotational position of the first port 401, the second port 402 and the pressure balancing assembly 122, thereby improving the accuracy of the pressure balancing assembly 122 in 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.

[0046] In the disclosed embodiment, the rotating member 1211 is partially exposed from the connecting hole 500 to the housing mechanism 11, so as to be driven to rotate relative to the housing mechanism 11. The circumferential outer wall of the portion of the rotating member 1211 exposed from the housing mechanism 11 may be provided with a rotation-stopping plane 12111 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 may also be connected by threaded connection, clamping, plugging or welding. The rotating member 1211 has a stepped shaft section, and the stepped shaft section forms a limited connection with the housing mechanism 11, so that a part of the stepped shaft section is exposed from the connecting hole 500 to the housing mechanism 11, and the other part of the stepped shaft section is restricted by the housing mechanism 11 to prevent the rotating member 1211 from being separated from the housing mechanism 11 through the connecting hole 500. A first sealing ring 30 is also provided between the stepped shaft section and the hole wall of the housing mechanism 11 to prevent hot water and cold water from overflowing from between the stepped shaft end and the hole wall. At least one of the stepped shaft section and the housing mechanism 11 is provided with a first mounting groove for mounting the first sealing ring 30 to ensure the position accuracy of the first sealing ring 30. The first sealing ring 30 forms a seal in the radial direction between the stepped shaft section and the hole wall, which can reduce the axial end face seal of the valve core 10, and avoid the axial end face seal extruding and deforming the first sealing ring 30 too much, resulting in poor rotation of the rotating mechanism 12 relative to the housing mechanism 11; and avoid the axial end face seal extruding and deforming the first sealing ring 30 too little, resulting in poor sealing, water leakage, and increased defective rate of the valve core 10.

[0047] In the exemplary embodiment, please combine Figure 1 , Figure 2 , Figure 5 , Figure 6 , Fig.16 and Fig.17The rotating member 1211 is provided with a first limiting portion 12112, and the housing mechanism 11 is provided at the second limiting portion 111. The first limiting portion 12112 and the second limiting portion 111 at least partially overlap along the first direction. During the 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 angular 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 convex structures and extend toward each other along the first direction. In the embodiment of the present disclosure, the number of the first limiting portions 12112 is two and they are spaced apart around the first direction, and the number of the second limiting portions 111 is two and they are spaced apart around the first direction, so that in the process of limiting the angular range of rotation of the rotating member 1211 relative to the shell mechanism 11, the two first limiting portions 12112 and the two second limiting portions 111 can abut against each other one by one, thereby ensuring the stability of the angular range of rotation of the rotating member 1211 relative to the shell mechanism 11.

[0048] The portion of the rotating member 1211 exposed outside the housing mechanism 11 is sleeved with a limiting ring 1213, 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 connected to the rotating member 1211 in a non-rotatable manner, for example, the circumferential outer side of the rotating member 1211 has an outer spur tooth surface 12113 extending along the first direction, and the inner edge of the limiting ring 1213 has an inner spur tooth surface 12131 extending along the first direction, and the outer spur tooth surface 12113 and the inner spur tooth surface 12131 are plugged in the first direction, so that the limiting ring 1213 is connected to the rotating member 1211 in a non-rotatable manner. In addition, the limit ring 1213 can be detachably connected to the rotating member 1211, so that the rotating member 1211 can adjust its relative position with the shell mechanism 11 and then be connected to the limit ring 1213 to prevent rotation, thereby limiting the angular range of rotation of the rotating member 1211 relative to the shell mechanism 11.

[0049] like Figure 2 and Fig.15The circumferential outer wall of the rotating member 1211 may be provided with a limiting protrusion 12114, and the housing mechanism 11 may be provided with a limiting groove 600 extending around the first direction. The limiting protrusion 12114 may be provided at the portion of the rotating member 1211 located inside the housing mechanism 11 and accommodated in the limiting groove 600. During the rotation of the rotating member 1211 relative to the housing mechanism 11, the limiting protrusion 12114 can respectively abut against two groove walls of the limiting groove 600 spaced apart around the first direction, so as to cooperate with the first limiting portion 12112 and the second limiting portion 111 to limit the angular range of rotation of the rotating member 1211 relative to the housing mechanism 11. The matching positions of the first limiting portion 12112 and the second limiting portion 111 and the matching positions of the limiting protrusion 12114 and the limiting groove 600 have a certain spacing distance along the first direction, thereby ensuring the stability of the angular range of limiting the rotation of the rotating member 1211 relative to the housing mechanism 11.

[0050] In the exemplary embodiment, please combine Figure 2 , Figure 5 , Figure 6 , Fig.11 and Fig.12 The rotating member 1211 is provided with a circumferential wall 12115 having a first through hole 701 and a second through hole 702. The valve seat 1212 is at least partially inserted into the circumferential wall 12115, connecting the first port 401 with the first through hole 701 and the second port 402 with the second through hole 702. In this way, the connection surface area between the valve seat 1212 and the rotating member 1211 can be increased by the provision of the circumferential wall 12115, thereby improving the connection stability. In the embodiment of the present disclosure, the circumferential outer wall of the valve seat 1212 is further provided with an annular protrusion 12121 to limit the size of the valve seat 1212 inserted into the interior of the circumferential wall 12115, thereby ensuring the connection accuracy between the first port 401 and the first through hole 701 and between the second port 402 and the second through hole 702, and allowing part of the valve seat 1212 to be exposed on the outside of the circumferential wall 12115, thereby facilitating the separation of the valve seat 1212 from the circumferential wall 12115 and facilitating the disassembly and assembly of the pressure balance assembly 122.

[0051] The arrangement of the first through hole 701 and the second through hole 702 ensures that the arrangement of the circumferential wall 12115 does not affect the connection or separation between the first port 401 and the second port 402 and the water outlet 300 during the rotation of the rotating assembly 121 relative to the housing mechanism 11. The first port 401 and the first through hole 701 can be coaxially arranged, or can be overlapped along the axial portion of the first port 401, as long as the connection is ensured. Similarly, the second port 402 and the second through hole 702 can be coaxially arranged, or can be overlapped along the axial portion of the second port 402, as long as the connection is ensured.

[0052] During the rotation of the rotating component 121 relative to the shell mechanism 11, the first through hole 701 rotates to be connected with the water outlet 300, so that the first port 401 is connected with the water outlet 300 through the first through hole 701; the first through hole 701 rotates to be blocked by the shell mechanism 11 and separated from the water outlet 300, so that the first port 401 is separated from the water outlet 300; the second through hole 702 rotates to be connected with the water outlet 300, so that the second port 402 is connected with the water outlet 300 through the second through hole 702; the second through hole 702 rotates to be blocked by the shell mechanism 11 and separated from the water outlet 300, so that the second port 402 is separated from the water outlet 300.

[0053] In the exemplary embodiment, please combine Figure 2 , Figure 5 , Figure 6 , Fig.11 and Fig.12 , the installation space 400 penetrates the valve seat 1212 along the second direction, and the first through hole 701 and the second through hole 702 are at least partially connected to the installation space 400 along the second direction. The second direction is perpendicular to the first direction. The second direction is parallel to Figure 2 The direction indicated by the arrow Y in the middle. In this way, the pressure balance component 122 is arranged along the radial direction of the rotating mechanism 12, which facilitates the water channel design of the hot water flow channel 100, the cold water flow channel 200 and the water outlet 300 connected to the pressure balance component 122. The first through hole 701 and the second through hole 702 can be arranged on the circumferential wall 12115 around the circumferential outer side of the installation space 400, and the water outlet 300 can be arranged on the shell mechanism 11 around the circumferential outer side of the circumferential wall 12115, so that the connecting structures constituting the discharge of hot water and cold water are all opened in the radial position of the valve core 10, and the axial position of the valve core 10 and the position between the radial and axial directions do not need to be opened with other connecting structures. Since other connecting structures need to meet certain flow requirements, the valve core 10 needs to have a larger radial size to open other connecting structures. The disclosed embodiment is conducive to reducing the radial size of the valve core 10, and then reducing the size of the valve body 20 assembled with the valve core 10, saving costs.

[0054] In the exemplary embodiment, please combine Figure 3 , Figure 5 , Figure 7b , Figure 8b , Figure 9b and Fig.10b , the pressure balance assembly 122 includes a valve sleeve 1221 and an inner core 1222; The valve sleeve 1221 is installed in the installation space 400, and the circumferential wall 12115 limits the two sides of the valve sleeve 1221 along the second direction to ensure the position stability of the valve sleeve 1221 relative to the valve seat 1212. In the embodiment of the present disclosure, the flow area of ​​the first through hole 701 is smaller than the flow area of ​​the first port 401, and the flow area of ​​the second through hole 702 is smaller than the flow area of ​​the second port 402, so that the circumferential wall 12115 partially blocks the first port 401 and the second port 402 along the second direction to limit the valve sleeve 1221. A sealing structure can also be provided between the circumferential outer side of the valve sleeve 1221 and the valve seat 1212, which, on the one hand, ensures the sealing between the valve sleeve 1221 and the valve seat 1212, and on the other hand, the valve sleeve 1221 and the valve seat 1212 also cause the sealing structure to undergo elastic deformation, thereby improving the connection stability between the valve sleeve 1221 and the valve seat 1212. A limiting structure 12211 may also be provided at the end of the valve sleeve 1221 to ensure the installation position accuracy of the valve sleeve 1221 and the valve seat 1212. The limiting structure 12211 is annular and abuts against the valve seat 1212.

[0055] The valve sleeve 1221 is provided with a first regulating port 403 and a second regulating port 404 in the circumferential direction, and two opposite ends of the valve sleeve 1221 along the second direction are communicated with the first through hole 701 and the second through hole 702 respectively.

[0056] During the rotation of the rotating assembly 121 relative to the housing mechanism 11 , the first regulating port 403 and the second regulating port 404 can be connected to or disconnected from the hot water flow channel 100 and the cold water flow channel 200 respectively.

[0057] The inner core 1222 can move relative to the valve sleeve 1221 along the second direction to adapt to the water pressure change of the water supplied to the hot water flow channel 100 and the cold water flow channel 200, and adjust the flow area between the first regulating port 403 and the first port 401 and between the second regulating port 404 and the second port 402. The inner core 1222 includes a tube body 12221 and a partition wall 12222 arranged on the tube body 12221. The partition wall 12222 divides the tube body 12221 into equal parts along the second direction, forming a first cavity 405 and a second cavity 406 located on both sides of the partition wall 12222. The first cavity 405 is connected to the first port 401. The second cavity 406 is connected to the second port 402. The tube body 12221 is provided with a first flow groove 407 and a second flow groove 408 respectively connected to the first cavity 405 and the second cavity 406 near the partition wall 12222. When the inner core 1222 moves relative to the valve sleeve 1221 along the second direction, the flow area between the first flow groove 407 and the first regulating port 403 and the flow area between the second flow groove 408 and the second regulating port 404 can be changed, thereby adjusting the hot water flow entering the first cavity 405 and the cold water flow entering the second cavity 406.

[0058] The circumferential wall 12115 avoids the movement of the inner core 1222 relative to the valve sleeve 1221 through the first through hole 701 and the second through hole 702. In this way, the inner core 1222 has a larger movement range in the second direction, which is convenient for controlling the flow of hot water and cold water.

[0059] In the embodiment of the present disclosure, the orthographic projection of the inner core 1222 on the shell mechanism 11 along the second direction is located outside the water outlet 300, so that the shell mechanism 11 can limit the range of movement of the inner core 1222 along the second direction, thereby preventing the inner core 1222 from separating from the shell mechanism 11 through the water outlet 300.

[0060] In the exemplary embodiment, please combine Figure 2 , Figures 4 to 6 , Figure 7a , Figure 8a , Figure 9a , Fig.10a , Fig.13 and Fig.14 The housing mechanism 11 includes a housing assembly 112 and a fixed valve plate 113. The fixed valve plate 113 is connected to the housing assembly 112 in a non-rotatable manner. In this way, the fixed valve plate 113 can be prevented from rotating when the rotating mechanism 12 rotates relative to the housing mechanism 11.

[0061] The hot water flow channel 100 and the cold water flow channel 200 respectively pass through the housing assembly 112 and the fixed valve plate 113 in sequence. The water outlet 300 and the connecting hole 500 are located in the housing assembly 112, and the rotating member 1211 is partially accommodated in the housing assembly 112 and is spaced apart from the fixed valve plate 113 along the first direction. The housing assembly 112 and the fixed valve plate 113 can be an integral structure or a separate structure.

[0062] The rotating assembly 121 also includes a movable valve disc 1214, which is non-rotatably connected to the side of the valve seat 1212 facing the fixed valve disc 113 and abuts against the fixed valve disc 113. In this way, the movable valve disc 1214 can be prevented from rotating relative to the valve seat 1212 during the rotation of the rotating mechanism 12 relative to the shell mechanism 11. In the embodiment of the present disclosure, the fixed valve disc 113 and the movable valve disc 1214 are both ceramic discs, which can improve the corrosion resistance of the fixed valve disc 113 and the movable valve disc 1214, and the structure is stable and not easily affected by temperature changes, thereby ensuring the matching accuracy of the fixed valve disc 113 and the movable valve disc 1214. The movable valve disc 1214 and the valve seat 1212 can be an integrated structure or a split structure.

[0063] The movable valve plate 1214 is provided with a first flow port 801 and a second flow port 802 which are in communication with the installation space 400. When the rotating assembly 121 rotates relative to the housing mechanism 11, the movable valve plate 1214 can slide relative to the fixed valve plate 113 and connect or disconnect the first flow port 801 and the second flow port 802 with the hot water flow channel 100 and the cold water flow channel 200, respectively.

[0064] In the embodiment of the present disclosure, the flow area of ​​the first flow port 801 facing the hot water channel 100 is smaller than the flow area of ​​the first flow port 801 facing the installation space 400, and the flow area of ​​the second flow port 802 facing the cold water channel 200 is smaller than the flow area of ​​the second flow port 802 facing the installation space 400. In this way, the movable valve plate 1214 and the fixed valve plate 113 have higher accuracy in controlling the hot water and cold water entering the movable valve plate 1214, and ensure that the hot water and cold water have a larger flow area to flow toward the installation space 400.

And the cooperation of the plurality of first plug-in portions 114 and the plurality of second plug-in portions 115 can make the shell assembly 112 and the fixed valve disc 113 non-rotatably connected. The number of the first plug-in portions 114 and the second plug-in portions 115 are both three, and they are distributed in a triangular shape, which further improves the stability of the non-rotatably connection between the shell assembly 112 and the fixed valve disc 113. The first plug-in portion 114 is arranged on the side of the housing assembly 112 facing the fixed valve disc 113 along the first direction, and the second plug-in portion 115 is arranged on the side of the fixed valve disc 113 facing the housing assembly 112 along the first direction. One of the first plug-in portion 114 and the second plug-in portion 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 surface area between the first plug-in portion 114 and the second plug-in portion 115, and facilitating the disassembly and assembly of the housing assembly 112 and the fixed valve disc 113. In addition, the provision of the supporting protrusion 1141 can also enhance the elastic deformation capacity of the protruding structure, and utilize the elastic deformation to facilitate the plug-in matching of the first plug-in portion 114 and the second plug-in portion 115, thereby reducing the assembly accuracy of the first plug-in portion 114 and the second plug-in portion 115. The side of the protrusion structure facing the groove structure and the side of the inner wall facing the protrusion structure can be provided with guide surfaces respectively or both to facilitate the plug-in matching of the first plug-in portion 114 and the second plug-in portion 115. In the embodiment of the present disclosure, the first plug-in portion 114 is a protrusion structure. The second plug-in portion 115 has a groove structure.

Thus, the first elastic seal 13 is provided to ensure the sealing between the hot water port 101 and the hot water outlet 102 and between the cold water port 201 and the cold water outlet 202, thereby preventing hot water and cold water from overflowing from between the housing assembly 112 and the fixed valve plate 113. By utilizing the elastic deformation performance of the first elastic seal 13, the sealing between the shell assembly 112 and the fixed valve plate 113 can be further improved, and the fixed valve plate 113 can be elastically abutted against the movable valve plate 1214 to ensure the matching accuracy between the fixed valve plate 113 and the movable valve plate 1214. The position of the fixed valve plate 113 relative to the first plug-in portion 114 is automatically adjusted according to the abutment force between the fixed valve plate 113 and the movable valve plate 1214, thereby reducing the rotational resistance of the movable valve plate 1214 during the rotation relative to the fixed valve plate 113.

The side of the lower shell 1122 facing the upper shell 1121 is provided with an anti-rotation protrusion 11221 and a clamping protrusion 11222. The number of the anti-rotation protrusions 11221 is consistent with the number of the anti-rotation grooves 1000 and is plugged in one-to-one.

[0075] In the exemplary embodiment, please combine Figure 1 , Figure 2 , Figure 5 , Figure 7a , Figure 8a , Figure 9a , Fig.10a , Fig.16 and Fig.17 The water outlet 300 is located on the circumferential outer wall of the shell mechanism 11 , and the hot water flow channel 100 and the cold water flow channel 200 respectively form a hot water inlet 103 and a cold water inlet 203 on the circumferential outer wall of the shell mechanism 11 .

[0076] The valve body 20 is provided with a first liquid inlet channel 1101, a second liquid inlet channel 1102 and a liquid outlet channel 1103. The valve body 20 is sleeved on the valve core 10 and is non-rotatably connected to the valve core 10. The first liquid inlet channel 1101 and the second liquid inlet channel 1102 are respectively connected with the hot water channel 100 and the cold water channel 200 in a one-to-one correspondence. A mixed liquid channel 1104 is formed between the valve body 20 and the valve core 10, and the mixed liquid channel 1104 is connected between the water outlet 300 and the liquid outlet channel 1103. In this way, hot water and cold water can enter the valve core 10 from the radial direction of the valve core 10, and water can be discharged from the radial direction of the valve core 10, forming a side-in and side-out valve core 10 structure, thereby preventing hot water and cold water from entering and exiting the valve core 10 from the end of the valve core 10. In order to achieve a certain flow requirement, the valve core 10 needs to have a larger radial dimension. In order to match the structure of the cold and hot water in and out of the end of the valve core 10, a corresponding water channel structure needs to be set inside the valve body 20, which increases the use of the material of the valve body 20, making the valve body 20 large in size and heavy in weight, and increasing the cost. In the embodiment of the present disclosure, the side-in and 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, making the valve body 20 smaller in size and lighter in weight, saving costs. A part of the circumferential outer side of the shell mechanism 11 matches the valve body 20 to ensure the sealing of the valve body 20, and a plurality of second sealing rings 40 can be set between the shell mechanism 11 and the valve body 20 to further improve the sealing between the shell mechanism 11 and the valve body 20. Another part of the circumferential outer side of the shell mechanism 11 is spaced from the valve body 20 to form a mixed liquid flow channel 1104. The valve core 10 is in a cold water outlet state, and the cold water enters the liquid outlet flow channel 1103 through the mixed liquid flow channel 1104. The valve core 10 is in the warm water outlet state, hot water and cold water enter the mixed liquid flow channel 1104 at the same time, and enter the liquid outlet flow channel 1103 through the mixed liquid flow channel 1104. The valve core 10 is in the hot water outlet state, and hot water enters the liquid outlet flow channel 1103 through the mixed liquid flow channel 1104.

[0077] In this disclosure, please combine Figure 1 and Fig.16 The valve core 10 and the valve body 20 are respectively provided with a first anti-rotation portion 15 and a second anti-rotation portion 21. One of the first anti-rotation portion 15 and the second anti-rotation portion 21 is a protrusion structure, and the other has a groove structure. The protrusion structure is received in the groove structure to prevent the valve core 10 and the valve body 20 from rotating.

[0078] In the exemplary embodiment, please combine Fig.16 and Fig.17 There are multiple liquid outlet channels 1103, which can be connected to multiple water outlet mechanisms respectively.

[0079] The housing mechanism 11 is provided with a drainage space 1200, and the drainage space 1200 is provided with a drainage pipe 50, and the drainage pipe 50 connects multiple liquid outlet channels 1103. In this way, the mixed liquid channel 1104 can be connected to one of the liquid outlet channels 1103, which reduces the design difficulty of the mixed liquid channel 1104, ensures that a larger part of the axial outer side of the housing mechanism 11 matches the valve body 20, and improves the stability of the connection.

[0080] In the disclosed embodiment, the number of the liquid outlet channels 1103 is two, and they are arranged on both sides of the valve core 10 along the second direction. The drainage tube 50 is a straight tube, which is sequentially plugged into the drainage space 1200 and the valve body 20 along the second direction. The liquid outlet channel 1103 and the drainage tube 50 are arranged in the same direction, which can facilitate the disassembly and assembly of the drainage tube 50, and further facilitate the disassembly and assembly 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 tube 50, and the liquid outlet channel 1103 can be connected to a water outlet mechanism at a lower position (for example, a bathtub water outlet), while the other liquid outlet channel 1103 can be connected to a water outlet mechanism at a higher position (for example, a top spray). For example, a pull-up valve is usually provided at the bathtub water outlet to block the water outlet of the bathtub. When the pull-up valve is opened, due to the height difference between the two connecting positions, water flows out of the bathtub spout by gravity instead of leaking from the overhead spray; when the pull-up valve is closed, water cannot flow out of the bathtub spout and instead flows out from the overhead spray, thus achieving water path switching.
