Description

Technical Field

[0001] This disclosure relates to, but is not limited to, kitchen and bathroom technologies, and particularly to a valve core, valve device, and water outlet system. Background Technology

[0002] When using a hot and cold water mixing system for showering or washing items, if someone uses water at the same time, it will cause a sudden change in water pressure, which can easily lead to sudden changes in water temperature. To solve this problem, valve cores with pressure balancing components are usually used in water systems such as showers and faucets. These valves can sense changes in water pressure and automatically adjust the flow of hot and cold water to minimize temperature fluctuations and achieve a constant temperature.

[0077] This disclosure provides a valve core, valve device, and 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 and body parts, thereby improving people's quality of life and health.

[0078] The water outlet system provided in the embodiments of this disclosure will now be described. The water outlet system may include a valve device. The water outlet system may also include a main body. The main body may be provided with a water passage structure, and the valve device may be installed on the main body and communicate with the water passage structure. The water passage structure introduces hot and cold water into the valve device and leads the water outlet from the valve device to at least one water outlet mechanism. The water outlet mechanism may include, but is not limited to, a faucet, shower head, overhead spray, or spray gun.

[0079] Please combine them together Figures 1 to 3 , Figures 5 to 10b , Figure 16 and Figure 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.

[0080] The rotating mechanism 12 includes a rotating component 121 and a pressure balancing component 122. The rotating component 121 is at least partially housed within the housing mechanism 11. The rotating component 121 has an installation space 400 extending through it, and a first port 401 and a second port 402 are formed on opposite sides of the rotating component 121. The rotating component 121 is configured to rotate relative to the housing mechanism 11 about a first direction, simultaneously connecting or disconnecting from the hot water channel 100 and the cold water channel 200, and connecting or separating at least one of the first port 401 and the second port 402 from the outlet 300. The first direction is parallel to... Figure 2 The direction indicated by the middle arrow X.

[0081] The pressure balancing component 122 is installed in the installation space 400 via at least one of the first port 401 and the second port 402, separating the first port 401 and the second port 402, and connecting the hot water flow channel 100 and the first port 401, as well as 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 to adjust the flow area between the hot water flow channel 100 and the first port 401, as well as between the cold water flow channel 200 and the second port 402.

[0082] like Figure 7a and Figure 7b As shown, the rotating assembly 121 is in its initial position. The rotating assembly 121 is simultaneously disconnected from both the hot water channel 100 and the cold water channel 200 (×), preventing both hot and cold water from entering the rotating assembly 121 and causing water to exit from the outlet 300. The valve core 10 is in the closed outlet state. At this time, the first port 401 and the second port 402 can be connected to or separated from the outlet 300.

[0083] like Figure 8a and Figure 8b As shown, the rotating component 121 rotates relative to the housing mechanism 11 to a first position. The rotating component 121 is simultaneously connected to the hot water channel 100 and the cold water channel 200, allowing hot and cold water to simultaneously enter the pressure balancing component 122. This allows the pressure balancing component 122 to adapt to changes in water pressure supplied to the hot water channel 100 and the cold water channel 200, adjusting the flow area between the hot water channel 100 and the first port 401, and between the cold water channel 200 and the second port 402. This 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, resulting in smaller fluctuations in the outlet water temperature of the valve device and achieving a constant temperature effect. At this time, the first port 401 is separated from the outlet 300 by the sealing of the housing mechanism 11, while the second port 402 is connected to the outlet 300. Hot water is obstructed, allowing only a small amount to enter the outlet 300, while cold water can smoothly enter the outlet 300. In the pressure balancing component 122, a small amount of hot water is discharged, causing the hot water to be in a pressurized state and the cold water to be in a depressurized state. This results in the hot water pressure being greater than the cold water pressure. The pressure balancing component 122 can reduce the flow area between the hot water channel 100 and the first port 401, while increasing the flow area between the cold water channel 200 and the second port 402, thus completely opening the space between the cold water channel 200 and the second port 402, achieving the maximum flow rate of cold water. This allows for water temperature regulation at the downstream end of the pressure balancing component 122, preventing a small flow rate when the outlet water is adjusted to cold water.

[0084] like Figure 9a and Figure 9b As shown, the rotating component 121 continues to rotate relative to the housing mechanism 11 to the second position. The rotating component 121 is simultaneously connected to the hot water channel 100 and the cold water channel 200, allowing hot and cold water to simultaneously enter the pressure balancing component 122. At this time, both the first port 401 and the second port 402 are connected to the outlet 300. Both hot and cold water can enter the outlet 300, mix to form warm water, and the valve core 10 is in a warm water outlet state. In the pressure balancing component 122, both hot and cold water are in a depressurized state, allowing the pressure balancing component 122 to adapt to changes in water pressure supplied to the hot water channel 100 and the cold water channel 200, adjusting the flow area between the hot water channel 100 and the first port 401, and between the cold water channel 200 and the second port 402. This 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, resulting in smaller fluctuations in the outlet water temperature of the valve device and achieving a constant temperature effect.

[0085] like Figure 10a and Figure 10bAs shown, the rotating component 121 continues to rotate relative to the housing mechanism 11 to the third position. The rotating component 121 is simultaneously connected to the hot water channel 100 and the cold water channel 200, allowing hot and cold water to simultaneously enter the pressure balancing component 122. This allows the pressure balancing component 122 to adapt to changes in water pressure supplied to the hot water channel 100 and the cold water channel 200, adjusting the flow area between the hot water channel 100 and the first port 401, and between the cold water channel 200 and the second port 402. This 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, resulting in smaller fluctuations in the outlet water temperature of the valve device and achieving a constant temperature effect. At this time, the second port 402 is separated from the outlet 300 by the sealing of the housing mechanism 11, while the first port 401 is connected to the outlet 300. Cold water is obstructed, allowing only a small amount to enter the outlet 300, while hot water can smoothly enter the outlet 300. In the pressure balancing component 122, a small amount of cold water is discharged, causing the cold water to be in a pressurized state and the hot water to be in a depressurized state. This results in the water pressure formed by the cold water being greater than that formed by the hot water. The pressure balancing component 122 can reduce the flow area between the cold water channel 200 and the second port 402, while increasing the flow area between the hot water channel 100 and the first port 401, thus completely opening the space between the hot water channel 100 and the first port 401, achieving the maximum flow rate of hot water. This allows for water temperature regulation at the downstream end of the pressure balancing component 122, preventing a small flow rate when the water is adjusted to hot water.

[0086] The rotating component 121 can continue to rotate relative to the housing mechanism 11 to the initial position, or it can rotate in the opposite direction to the initial position.

[0087] In this embodiment, there are two water outlets 300, which correspond one-to-one with the first port 401 and the second port 402. This reduces the range of rotation angle of the rotating component 121 relative to the housing mechanism 11 when the valve core 10 switches between water outlet states (water outlet closed state, cold water outlet state, warm water outlet state, and hot water outlet state), making the water outlet state switching faster and more sensitive.

[0088] It can be understood that in other embodiments, the number of outlets 300 can also be one.

[0089] Implementing the embodiments disclosed herein will have the following beneficial effects:

[0090] The valve core 10 described above is used in valve devices and water outlet systems. Besides controlling water flow rate and temperature to maintain a constant water temperature, it also facilitates the assembly and disassembly of the pressure balancing component 122. Specifically, the valve core 10 includes a housing mechanism 11 with a hot water flow channel 100, a cold water flow channel 200, and an outlet 300, and a rotating mechanism 12 including a rotating component 121 and a pressure balancing component 122. The rotating component 121 has an installation space 400 extending through it. The pressure balancing component 122 is installed in the installation space 400 via one of the first port 401 and the second port 402 of the rotating component 121. This facilitates the assembly and disassembly of the pressure balancing component 122, making the installation space 400 a single integrated structure, reducing assembly costs, and improving the structural stability of the pressure balancing component 122's installation position, thus ensuring the stability of the pressure balancing component 122's operation.

[0091] During the rotation of the rotating component 121 relative to the housing mechanism 11, it can be connected or disconnected simultaneously with the hot water flow channel 100 and the cold water flow channel 200. In this way, the hot water and cold water can be controlled at the front end of the pressure balancing component 122 without the need to set up a separate one-way valve to prevent the hot and cold water from flowing into each other, and the water temperature can be adjusted at the front end of the pressure balancing component 122.

[0092] During the rotation of the rotating component 121 relative to the housing 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 balancing component 122 to avoid a small water flow rate when the water outlet is adjusted to cold or hot water.

[0093] In the exemplary embodiments, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 11 and Figure 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 mounting space 400 is provided in the valve seat 1212, and the valve seat 1212 is anti-rotatingly connected to the rotating member 1211.

[0094] The connection hole 500 increases the contact area between the rotating component 1211 and the housing mechanism 11, improves the stability of the rotation of the rotating component 1211 relative to the housing mechanism 11, and enables the housing mechanism 11 to restrict the radial movement of the rotating component 1211. This ensures the accuracy of the rotational positions of the first port 401, the second port 402, and the pressure balancing component 122, thereby improving the accuracy of the pressure balancing component 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.

[0095] In this embodiment, the rotating member 1211 is partially exposed from the housing mechanism 11 through the connecting hole 500, 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 to the housing mechanism 11 may be provided with an anti-rotation plane 12111 to facilitate an anti-rotation connection between the rotating member 1211 and the driving structure. Furthermore, the rotating member 1211 and the driving structure can also be connected by threaded connection, snap-fit, plug-in, or welding. The rotating member 1211 has a stepped shaft segment, which forms a limiting connection with the housing mechanism 11, such that a portion of the stepped shaft segment is exposed from the housing mechanism 11 through the connecting hole 500, while the other portion of the stepped shaft segment is restricted by the housing mechanism 11, preventing the rotating member 1211 from separating from the housing mechanism 11 through the connecting hole 500. A first sealing ring 30 is also provided between the stepped shaft segment and the housing mechanism 11 forming the wall of the connecting hole 500 to prevent hot and cold water from overflowing 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 positional accuracy of the first sealing ring 30. The first sealing ring 30 forms a radial seal between the stepped shaft section and the bore wall, which can reduce the axial end face sealing of the valve core 10 and avoid excessive compression deformation of the first sealing ring 30 by the axial end face sealing, which would cause the rotating mechanism 12 to rotate poorly relative to the housing mechanism 11; and avoid poor sealing performance and leakage caused by insufficient compression deformation of the first sealing ring 30 by the axial end face sealing, which would increase the failure rate of the valve core 10.

[0096] In the exemplary embodiments, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , 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 along the first circumferential 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. Both the first limiting portion 12112 and the second limiting portion 111 are protruding structures and extend towards each other along the first direction. In this embodiment, there are two first limiting parts 12112, which are spaced apart around the first direction, and two second limiting parts 111, which are also spaced apart around the first direction. This ensures that during the process of limiting the angular range of rotation of the rotating member 1211 relative to the housing mechanism 11, the two first limiting parts 12112 and the two second limiting parts 111 can abut against each other in a one-to-one manner, thereby ensuring the stability of limiting the angular range of rotation of the rotating member 1211 relative to the housing mechanism 11.

[0097] A limiting ring 1213 is fitted onto the portion of the rotating component 1211 exposed outside the housing mechanism 11. A first limiting portion 12112 is disposed on the side of the limiting ring 1213 facing the housing mechanism 11. A second limiting portion 111 is disposed on the side of the housing mechanism 11 facing the limiting ring 1213. The limiting ring 1213 is connected to the rotating component 1211 to prevent rotation. For example, the outer circumferential side of the rotating component 1211 has an outer straight tooth surface 12113 extending in a first direction, and the inner edge 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 into each other in the first direction, so that the limiting ring 1213 is connected to the rotating component 1211 to prevent rotation. Furthermore, the limiting ring 1213 can be detachably connected to the rotating member 1211, so that after the rotating member 1211 adjusts its relative position with the housing mechanism 11, it can be connected to the limiting ring 1213 to stop rotation, thereby limiting the range of rotation angle of the rotating member 1211 relative to the housing mechanism 11.

[0098] like Figure 2 and Figure 15The circumferential outer wall of the rotating member 1211 may also be provided with a limiting protrusion 12114, and the housing mechanism 11 may also be provided with a limiting groove 600 extending around the first direction. The limiting protrusion 12114 may be provided in the part of the rotating member 1211 located inside the housing mechanism 11 and received in the limiting groove 600. During the rotation of the rotating member 1211 relative to the housing mechanism 11, the limiting protrusion 12114 can abut against two groove walls of the limiting groove 600 that are spaced apart around the first direction, so as to cooperate with the first limiting part 12112 and the second limiting part 111 to limit the angular range of rotation of the rotating member 1211 relative to the housing mechanism 11. The cooperation positions of the first limiting part 12112 and the second limiting part 111, as well as the cooperation positions of the limiting protrusion 12114 and the limiting groove 600, have a certain distance between them along the first direction, thereby ensuring the stability of limiting the angular range of rotation of the rotating member 1211 relative to the housing mechanism 11.

[0099] In the exemplary embodiments, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 11 and Figure 12 The rotating component 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 to the first through hole 701 and the second port 402 to the second through hole 702. This arrangement of the circumferential wall 12115 increases the contact area between the valve seat 1212 and the rotating component 1211, thereby improving connection stability. In this embodiment, 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 circumferential wall 12115, ensure the communication accuracy between the first port 401 and the first through hole 701 and the second port 402 and the second through hole 702, and make the valve seat 1212 partially exposed on the outside of the circumferential wall 12115, so as to facilitate the separation of the valve seat 1212 from the circumferential wall 12115 and facilitate the disassembly and assembly of the pressure balancing assembly 122.

[0100] 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 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 overlapped along the axial portion of the first port 401, as long as they are connected. Similarly, the second port 402 and the second through hole 702 can be coaxially arranged or overlapped along the axial portion of the second port 402, as long as they are connected.

[0101] During the rotation of the rotating component 121 relative to the housing mechanism 11, the first through hole 701 rotates to communicate with the outlet 300, so that the first port 401 is connected to the outlet 300 through the first through hole 701; the first through hole 701 rotates to be blocked by the housing mechanism 11 and separated from the outlet 300, thereby separating the first port 401 from the outlet 300; the second through hole 702 rotates to communicate with the outlet 300, so that the second port 402 is connected to the outlet 300 through the second through hole 702; the second through hole 702 rotates to be blocked by the housing mechanism 11 and separated from the outlet 300, thereby separating the second port 402 from the outlet 300.

[0102] In the exemplary embodiments, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 11 and Figure 12 The mounting space 400 extends through the valve seat 1212 along a second direction, and the first through hole 701 and the second through hole 702 are at least partially connected to the mounting 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 middle arrow Y. This arrangement allows the pressure balancing assembly 122 to be radially positioned along the rotating mechanism 12, facilitating the water circuit design of the hot water channel 100, cold water channel 200, and outlet 300 connected to the pressure balancing assembly 122. The first through hole 701 and the second through hole 702 can be arranged around the circumferential outer side of the installation space 400 on the circumferential wall 12115, and the outlet 300 can be arranged around the circumferential outer side of the circumferential wall 12115 on the housing mechanism 11. This ensures that the communication structures constituting the hot and cold water discharge are all located radially at the valve core 10, eliminating the need for other communication structures at the axial position of the valve core 10 or at positions between the radial and axial directions. Since other communication structures need to meet certain flow requirements, the valve core 10 requires a larger radial dimension to accommodate these structures. This embodiment of the present disclosure facilitates reducing the radial dimension of the valve core 10, thereby reducing the size of the valve body 20 assembled with the valve core 10 and saving costs.

[0103] In the exemplary embodiments, please refer to Figure 3 , Figure 5 , Figure 7b , Figure 8b , Figure 9b and Figure 10b The pressure balancing assembly 122 includes a valve sleeve 1221 and an inner core 1222;

[0104] The valve sleeve 1221 is installed in the installation space 400. The circumferential wall 12115 limits the valve sleeve 1221 on both sides along the second direction to ensure the positional stability of the valve sleeve 1221 relative to the valve seat 1212. In this embodiment, 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 outer circumferential side of the valve sleeve 1221 and the valve seat 1212. On the one hand, this ensures the sealing performance between the valve sleeve 1221 and the valve seat 1212. On the other hand, the valve sleeve 1221 and the valve seat 1212 also cause the sealing structure to undergo elastic deformation, 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.

[0105] The valve sleeve 1221 is provided with a first adjustment port 403 and a second adjustment port 404 in the circumferential direction. The two opposite ends of the valve sleeve 1221 along the second direction are respectively connected to the first through hole 701 and the second through hole 702.

[0106] During the rotation of the rotating component 121 relative to the housing mechanism 11, the first adjustment port 403 and the second adjustment port 404 can be connected or disconnected from the hot water flow channel 100 and the cold water flow channel 200, respectively.

[0107] The inner core 1222 is movable relative to the valve sleeve 1221 along the second direction to adapt to changes in water pressure supplied to the hot water channel 100 and the cold water channel 200, and to 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 disposed on the tube body 12221. The partition wall 12222 divides the tube body 12221 equally 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 communicates with the first port 401. The second cavity 406 communicates with the second port 402. The tube body 12221 near the partition wall 12222 has a first flow groove 407 and a second flow groove 408 communicating with the first cavity 405 and the second cavity 406, respectively. As the inner core 1222 moves relative to the valve sleeve 1221 in the second direction, it can change the flow area between the first flow channel 407 and the first regulating port 403 and the second flow channel 408 and the second regulating port 404, thereby adjusting the flow rate of hot water entering the first cavity 405 and the flow rate of cold water entering the second cavity 406.

[0108] 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. This allows the inner core 1222 to have a large range of movement in the second direction, which facilitates the control of the flow rate of hot and cold water.

[0109] In this embodiment, the orthogonal projection of the inner core 1222 onto the housing mechanism 11 along the second direction is located outside the outlet 300, so that the housing mechanism 11 can restrict the range of movement of the inner core 1222 along the second direction, and prevent the inner core 1222 from separating from the housing mechanism 11 through the outlet 300.

[0110] In the exemplary embodiments, please refer to Figure 2 , Figures 4 to 6 , Figure 7a , Figure 8a , Figure 9a , Figure 10a , Figure 13 and Figure 14 The housing mechanism 11 includes a housing assembly 112 and a fixed valve plate 113. The fixed valve plate 113 is anti-rotationally connected to the housing assembly 112. This prevents the fixed valve plate 113 from rotating during the rotation of the rotating mechanism 12 relative to the housing mechanism 11.

[0111] Hot water channel 100 and cold water channel 200 pass through housing assembly 112 and fixed valve plate 113 respectively. Outlet 300 and connection hole 500 are located in housing assembly 112. Rotating member 1211 is partially housed in housing assembly 112 and spaced apart from fixed valve plate 113 along a first direction. Housing assembly 112 and fixed valve plate 113 can be an integral structure or separate structures.

[0112] The rotating assembly 121 also includes a movable valve plate 1214, which is anti-rotatingly connected to the side of the valve seat 1212 facing the fixed valve plate 113 and abuts against the fixed valve plate 113. This prevents the movable valve plate 1214 from rotating relative to the valve seat 1212 during the rotation of the rotating mechanism 12 relative to the housing mechanism 11. In this embodiment, both the fixed valve plate 113 and the movable valve plate 1214 are ceramic plates, which improves their corrosion resistance and ensures structural stability, making them less susceptible to temperature changes and guaranteeing the precision of their fit. The movable valve plate 1214 and the valve seat 1212 can be an integral structure or separate structures.

[0113] The movable valve plate 1214 is provided with a first flow port 801 and a second flow port 802 communicating with the installation space 400. During the 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 connect or disconnect the first flow port 801 and the second flow port 802 with the hot water channel 100 and the cold water channel 200, respectively.

[0114] In this embodiment, the flow area of ​​the first flow port 801 facing the hot water flow 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 flow channel 200 is smaller than the flow area of ​​the second flow port 802 facing the installation space 400. This makes the movable valve plate 1214 and the fixed valve plate 113 more accurate in controlling the hot and cold water to enter the movable valve plate 1214, and ensures that the hot and cold water have a larger flow area to flow towards the installation space 400.

[0115] In the exemplary embodiments, please refer to Figure 4 and Figure 13The housing assembly 112 and the fixed valve plate 113 are detachably connected. The housing assembly 112 is provided with multiple first insertion portions 114. The first insertion portions 114 extend along a first direction, and the fixed valve plate 113 is provided with multiple second insertion portions 115, which also extend along the first direction. The multiple first insertion portions 114 and multiple second insertion portions 115 are inserted into each other in a one-to-one correspondence. This facilitates the maintenance and replacement of the fixed valve plate 113. Furthermore, the cooperation of the multiple first insertion portions 114 and multiple second insertion portions 115 ensures an anti-rotation connection between the housing assembly 112 and the fixed valve plate 113. The number of first insertion portions 114 and two insertion portions 115 are both three, and they are arranged in a triangular pattern, further improving the stability of the anti-rotation connection between the housing assembly 112 and the fixed valve plate 113. A first insertion portion 114 is disposed on the side of the housing assembly 112 facing the fixed valve plate 113 along the first direction, and a second insertion portion 115 is disposed on the side of the fixed valve plate 113 facing the housing assembly 112 along the first direction. One of the first insertion portion 114 and the second insertion 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 by the inner wall, reducing the connection surface area between the first insertion portion 114 and the second insertion portion 115, facilitating the assembly and disassembly of the housing assembly 112 and the fixed valve plate 113. Furthermore, the supporting protrusion 1141 also enhances the elastic deformation capability of the protruding structure, and utilizes elastic deformation to facilitate the insertion and mating of the first insertion portion 114 and the second insertion portion 115, reducing the assembly accuracy of the first insertion portion 114 and the second insertion portion 115. Guide surfaces may be provided, either separately or both, on the side of the protruding structure facing the groove structure and on the side of the inner wall facing the protruding structure, to facilitate the insertion and engagement of the first insertion part 114 and the second insertion part 115. In this embodiment, the first insertion part 114 is a protruding structure. The second insertion part 115 has a groove structure.

[0116] In the exemplary embodiments, please refer to Figures 4 to 6 The fixed valve plate 113 is movable relative to the first insertion portion 114 along the first direction. The hot water flow channel 100 and the cold water flow channel 200 form a hot water inlet 101 and a cold water inlet 201 on the side of the housing assembly 112 facing the fixed valve plate 113, respectively. The hot water flow channel 100 and the cold water flow channel 200 form a hot water outlet 102 and a cold water outlet 202 on the fixed valve plate 113, respectively.

[0117] The valve core 10 also includes a first elastic seal 13, which is clamped between the housing assembly 112 and the fixed valve plate 113 along a first direction. The first elastic seal 13 forms a first through hole 901 and a second through hole 902. The first through hole 901 connects the hot water inlet 101 and the hot water outlet 102, and the second through hole 902 connects the cold water inlet 201 and the cold water outlet 202. Thus, the first elastic seal 13 ensures a tight seal between the hot water inlet 101 and the hot water outlet 102, and between the cold water inlet 201 and the cold water outlet 202, preventing hot and cold water from overflowing between the housing assembly 112 and the fixed valve plate 113. By utilizing the elastic deformation properties of the first elastic seal 13, the sealing performance between the housing 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 fitting 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 insertion part 114 can be automatically adjusted according to the magnitude of 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 process relative to the fixed valve plate 113.

[0118] In this embodiment of the present disclosure, at least one of the housing assembly 112 and the fixed valve plate 113 is further provided with a first positioning groove for mounting the first elastic seal 13, so as to ensure the positional accuracy of the first elastic seal 13.

[0119] In the exemplary embodiments, please refer to Figure 4 , Figure 6 , Figure 11 , Figure 12 and Figure 14 The valve seat 1212 and the movable valve plate 1214 are detachably connected. The valve seat 1212 is provided with multiple third insertion portions 12122. The third insertion portions 12122 extend along a first direction. The movable valve plate 1214 is provided with multiple fourth insertion portions 12141, which also extend along the first direction. The multiple third insertion portions 12122 and the multiple fourth insertion portions 12141 are inserted one-to-one. This facilitates the maintenance and replacement of the movable valve plate 1214. Furthermore, the cooperation of the multiple third insertion portions 12122 and the multiple fourth insertion portions 12141 ensures a non-rotational connection between the valve seat 1212 and the movable valve plate 1214. There are three first insertion portions 114 and three second insertion portions 115, which are spaced apart around the first direction. This further improves the stability of the non-rotational connection between the valve seat 1212 and the movable valve plate 1214. In addition, in some embodiments, the number of the first plug-in portion 114 and the second plug-in portion 115 may both be three or more.

[0120] The third insertion portion 12122 is disposed on the side of the valve seat 1212 facing the movable valve plate 1214 along the first direction, and the fourth insertion portion 12141 is disposed on the side of the movable valve plate 1214 facing the valve seat 1212 along the first direction. One of the third insertion portion 12122 and the fourth insertion portion 12141 is a protruding structure, and the other has a groove wall forming a notch. The protruding structure is inserted into the notch and abuts against the groove wall. In this embodiment, the third insertion portion 12122 is a protruding structure. The fourth insertion portion 12141 has a notch.

[0121] In the exemplary embodiments, please refer to Figures 4 to 6 and Figure 12 The movable valve plate 1214 can move relative to the third insertion part 12122 in the first direction. The valve seat 1212 is provided with a first flow space 409 and a second flow space 410, which are respectively connected to the installation space 400.

[0122] The valve core 10 also includes a second elastic seal 14, which is clamped between the valve seat 1212 and the movable valve plate 1214 along a first direction. The second elastic seal 14 forms a third through hole 903 and a fourth through hole 904. The third through hole 903 connects the first flow space 409 and the first flow port 801, and the fourth through hole 904 connects the second flow space 410 and the second flow port 802. Thus, the second elastic seal 14 ensures a tight seal between the first flow space 409 and the first flow port 801, and between the second flow space 410 and the second flow port 802, preventing hot and cold water from overflowing between the valve seat 1212 and the movable valve plate 1214. By utilizing the elastic deformation properties of the second elastic seal 14, the sealing performance between the valve seat 1212 and the movable valve plate 1214 is further improved, and the movable valve plate 1214 is elastically abutted against the fixed valve plate 113, ensuring the fitting accuracy between the fixed valve plate 113 and the movable valve plate 1214. The position of the movable valve plate 1214 relative to the third insertion part 12122 is automatically adjusted according to the magnitude of 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 process relative to the fixed valve plate 113.

[0123] In this embodiment of the present disclosure, at least one of the valve seat 1212 and the movable valve plate 1214 is further provided with a second positioning groove for mounting the second elastic seal 14, so as to ensure the positional accuracy of the second elastic seal 14.

[0124] In the exemplary embodiment, please combine with Figure 1 , Figure 2 , Figure 5 and Figure 6The housing assembly 112 includes a detachably connected upper housing 1121 and a lower housing 1122. A connection hole 500 is provided in the upper housing 1121, and a fixed valve plate 113 is anti-rotatingly connected to the lower housing 1122. The upper housing 1121 and the lower housing 1122 are arranged sequentially along a first direction. The upper housing 1121 abuts against the side of the rotating member 1211 opposite to the movable valve plate 1214, and the lower housing 1122 abuts against the side of the fixed valve plate 113 opposite to the movable valve plate 1214. The detachable upper housing 1121 and lower housing 1122 facilitate the installation of the rotating mechanism 12, the first elastic seal 13, the fixed valve plate 113, and the first elastic seal 13. They also clamp the rotating mechanism 12, the first elastic seal 13, the fixed valve plate 113, and the first elastic seal 13 along a first direction, 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 positional accuracy of the pressure balance assembly 122. The anti-rotation connection between the upper housing 1121 and lower housing 1122 prevents the rotating mechanism 12 from rotating relative to the housing mechanism 11, thus avoiding the upper housing 1121 from rotating relative to the lower housing 1122. Furthermore, the upper housing 1121 and lower housing 1122 can be detachably connected by snap-fit, plug-in, or other methods. In this embodiment, the side of the upper housing 1121 facing the lower housing 1122 is provided with an anti-rotation groove 1000 and a snap-fit ​​arm 11211. Multiple anti-rotation grooves 1000 and multiple snap-fit ​​arms 11211 are arranged around the first direction. Each snap-fit ​​arm 11211 has a snap-fit ​​groove. On the side of the lower housing 1122 facing the upper housing 1121, there are anti-rotation protrusions 11221 and snap-fit ​​protrusions 11222. The number of anti-rotation protrusions 11221 is the same as the number of anti-rotation grooves 1000, and they are inserted into each other in a one-to-one correspondence. The number of snap-fit ​​protrusions 11222 is the same as the number of snap-fit ​​arms 11211, and they are snapped into their corresponding snap-fit ​​grooves in a one-to-one correspondence.

[0125] In the exemplary embodiments, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 7a , Figure 8a , Figure 9a , Figure 10a , Figure 16 and Figure 17 The 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 form a hot water inlet 103 and a cold water inlet 203 on the circumferential outer wall of the shell mechanism 11, respectively.

[0126] The valve body 20 is provided with a first inlet channel 1101, a second inlet channel 1102, and an outlet channel 1103. The valve body 20 is sleeved on the valve core 10 and is anti-rotatingly connected to the valve core 10. The first inlet channel 1101 and the second inlet channel 1102 are respectively connected to the hot water channel 100 and the cold water channel 200. A mixing channel 1104 is formed between the valve body 20 and the valve core 10, and the mixing channel 1104 is connected between the outlet 300 and the outlet channel 1103. This allows hot and cold water to enter the valve core 10 radially and exit radially, forming a side-inlet and side-outlet valve core 10 structure. This prevents hot and cold water from entering and exiting the valve core 10 from the end. To achieve a certain flow rate, the valve core 10 needs to have a large radial dimension. To accommodate the hot and cold water inlet / outlet structure of the valve core 10, a corresponding water passage structure needs to be installed inside the valve body 20. This increases the material usage of the valve body 20, making it larger and heavier, thus increasing costs. In this embodiment, the side-inlet / side-outlet valve core 10 structure avoids the need for additional water passage structures on top of the existing water passage structure, resulting in a smaller and lighter valve body 20 and saving costs. A portion of the outer circumferential side of the housing mechanism 11 matches the valve body 20 to ensure a tight seal. Multiple second sealing rings 40 can be installed between the housing mechanism 11 and the valve body 20 to further enhance the seal. Another portion of the outer circumferential side of the housing mechanism 11 is spaced apart from the valve body 20, forming a mixing channel 1104. When the valve core 10 is in the cold water outlet state, cold water enters the outlet channel 1103 through the mixing channel 1104. When valve core 10 is in the warm water outlet state, hot and cold water simultaneously enter the mixing channel 1104 and then enter the outlet channel 1103. When valve core 10 is in the hot water outlet state, hot water enters the outlet channel 1103 through the mixing channel 1104.

[0127] In the embodiments disclosed herein, please refer to the following: Figure 1 and Figure 16 The valve core 10 and the valve body 20 are respectively provided with a first anti-rotation part 15 and a second anti-rotation part 21. One of the first anti-rotation part 15 and the second anti-rotation part 21 is a protruding structure, and the other has a groove structure. The protruding structure is received in the groove structure so that the valve core 10 and the valve body 20 are connected in an anti-rotation connection.

[0128] In the exemplary embodiments, please refer to Figure 16 and Figure 17 There are multiple liquid outlet channels 1103, which can be connected to multiple water outlet mechanisms respectively.

[0129] The housing mechanism 11 is provided with a drainage space 1200, and the drainage space 1200 is provided with a drainage pipe 50, which connects multiple liquid outlet channels 1103. This allows the mixing channel 1104 to be connected to one of the liquid outlet channels 1103, reducing the design difficulty of the mixing channel 1104, ensuring that a larger portion of the outer axial side of the housing mechanism 11 matches the valve body 20, and improving the stability of the connection.

[0130] In this embodiment, there are two liquid outlet channels 1103, which are arranged on both sides of the valve core 10 along the second direction. The drain pipe 50 is a straight pipe, which is sequentially inserted into the drain space 1200 and the valve body 20 along the second direction. The liquid outlet channels 1103 and the drain pipe 50 are arranged in the same direction, which facilitates the disassembly and assembly of the drain pipe 50, and thus facilitates the disassembly and assembly of the valve core 10 and the valve body 20. In addition, the connection position of the mixing channel 1104 with one of the liquid outlet channels 1103 is higher than the connection position of the liquid outlet channel 1103 with the drain pipe 50, and the liquid outlet channel 1103 can be connected to a lower water outlet mechanism (e.g., a bathtub spout), while the other liquid outlet channel 1103 can be connected to a higher water outlet mechanism (e.g., a top spray). For example, a pull valve is usually provided at the bathtub spout to block water from flowing out of the bathtub spout. When the pull valve is open, the height difference between the two connected positions allows water to flow out of the bathtub spout by gravity instead of leaking from the overhead shower. When the pull valve is closed, water cannot flow out of the bathtub spout and instead flows out from the overhead shower, thus switching the water path.
