[0041] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0042] As Figures 1 - 10 shown, the seat ring assembly provided by an embodiment of the present utility model includes a seat ring 1 and a waterway control mechanism 2.

[0043] Two seat ring ear plates 11 are provided at the rear end of the seat ring 1, and the waterway control mechanism 2 is installed on one side of one seat ring ear plate 11.

[0044] The waterway control mechanism 2 includes a mechanism main body 21 that is pivotally connected to the seat ring ear plate 11 and has a pressure relief hole 213, a cover 22 connected to one side of the mechanism main body 21 and having a water inlet pipe 222 and a water outlet pipe 223, a sealing valve 23 provided in the cover 22 and having a water flow hole 231, and a swing arm 24 that is pivotally provided between the mechanism main body 21 and the seat ring ear plate 11 and can be driven to swing by the rotatable seat ring ear plate 11.

[0045] The pressure relief hole 213 and the water inlet 221a of the cover 22 are on opposite sides of the sealing valve 23. A plug cap 25 is provided at one end of the swing arm 24. The plug cap 25 can open or close the pressure relief hole 213 as the swing arm 24 swings. The sealing valve 23 can conduct or cut off the water path between the water inlet pipe 222 and the water outlet pipe 223 as the pressure relief hole 213 opens and closes.

[0046] The seat ring assembly provided by the present utility model includes a seat ring 1 and a water path control mechanism 2. On the left and right sides of the rear end of the seat ring 1, there is respectively provided a seat ring ear plate 11. The seat ring ear plate 11 is provided with a through hole 111 for assembling with a shaft on a mounting seat or other components. The seat ring 1 can rotate around the shaft to achieve opening and closing. When the seat ring 1 is in the closed state as referred to in the present utility model, it means that the seat ring 1 is placed on Figures 12 - 13 the toilet body 3 as described above. When the seat ring 1 is in the fully open state as referred to in the present utility model, it means that the seat ring 1 is flipped open from the toilet body 3, and the opening angle is greater than 90°. The process of the seat ring 1 switching from the closed state to the fully open state is the opening and closing process of the seat ring 1 being manually or electrically operated. The process of the seat ring 1 switching from the fully open state to the closed state is the closing process of the seat ring 1 being manually or electrically operated. The default state of the seat ring 1 can be the closed state or the fully open state.

[0047] The water path control mechanism 2 is used to control Figure 13 the pre-rinse nozzle 6 as shown to spray a small amount of water into the toilet bowl 31 to moisten the rear side wall surface of the toilet bowl 31 and reduce dirt adhesion.

[0048] In the present utility model, the water path control mechanism 2 is a pure mechanical structure, which is linked with the seat ring 1 and automatically opens or closes the water path of the pre-rinse nozzle 6 as the seat ring 1 rotates.

[0049] The water path control mechanism 2 is installed on one side of a seat ring ear plate 11. Preferably, the water path control mechanism 2 is installed inside a seat ring ear plate 11.

[0050] The water path control mechanism 2 includes a mechanism main body 21, a cover 22, a sealing valve 23, a swing arm 24, a plug cap 25, etc.

[0051] The mechanism main body 21 can be a plate-like structure or a block-like structure. A pressure relief hole 213 is provided in the area where it is assembled with the cover 22. An installation shaft 211 is provided on the outer side of the mechanism main body 21 for assembling in the through hole 111 of the seat ring ear plate 11. The seat ring ear plate 11 can rotate relative to the installation shaft 211. Preferably, a connection seat 212 is provided in the area where the mechanism main body 21 is assembled with the cover 22, and the pressure relief hole 213 penetrates through the connection seat 212. The connection seat 212 is used for docking with the opening of the cover 22.

[0052] The cover 22 is box-shaped or hemispherical and has a cavity 221. The water inlet of the cavity 221 is also the water inlet 221a of the cover 22. A water inlet pipe 222 is connected to the water inlet 221a and is used to connect to the water supply pipeline 7 of the toilet. Specifically, the water inlet pipe 222 can be connected to the water supply pipeline 7 through a hose. Preferably, the water inlet pipe 222 is perpendicular to the seat ear plate 11 and is located at the middle position of the cover 22. A water outlet pipe 223 is also provided on one side of the cover 22, which is used to connect to the pre-rinse nozzle 6 to supply water to the pre-rinse nozzle 6. Specifically, the water outlet pipe 223 can be connected to the pre-rinse nozzle 6 through a hose.

[0053] The sealing valve 23 is a diaphragm valve and is assembled in the cavity 221. The four peripheral edges of the sealing valve 23 are sealingly connected to the wall surface of the cavity 221. One side of the sealing valve 23 facing the water inlet 221a can be in sealing contact with the wall surface around the water inlet 221a, thereby dividing the cavity 221 into a chamber where the water inlet 221a is located, a first chamber 221b, and a second chamber 221c. The first chamber 221b is the part between the four peripheral edges of the sealing valve 23 and the wall surface around the water inlet 221a. The second chamber 221c is the part between the sealing valve 23 and the connecting seat 212, and the pressure relief hole 213 is communicated with the second chamber 221c.

[0054] The water outlet of the cover 22 is provided in the first chamber 221b, and the water outlet pipe 223 is connected to the water outlet of the cover 22. Therefore, when one side of the sealing valve 23 facing the water inlet 221a is in sealing contact with the wall surface around the water inlet 221a, the first chamber 221b is disconnected from the water inlet 221a, the water path between the water inlet pipe 222 and the water outlet pipe 223 is disconnected, and no water is discharged from the water outlet pipe 223. Therefore, the pre-rinse nozzle 6 does not spray water; when one side of the sealing valve 23 facing the water inlet 221a leaves the wall surface around the water inlet 221a, the first chamber 221b is communicated with the water inlet 221a, the water path between the water inlet pipe 222 and the water outlet pipe 223 is conducted, the water outlet pipe 223 drains water, and the pre-rinse nozzle 6 performs a water spraying operation.

[0055] A water flow hole 231 is opened on the sealing valve 23, which communicates the water inlet 221a and the second chamber 221c. When the water pressure between the first chamber 221b and the second chamber 221c is equal, since the area of the sealing valve 23 facing the second chamber 221c is larger than the area of the sealing valve 23 facing the water inlet 221a, therefore, the sealing valve 23 will deform toward the water inlet 221a side and thus be in sealing contact with the wall surface around the water inlet 221a, and the first chamber 221b is disconnected from the water inlet 221a. When the water in the second chamber 221c is discharged and the pressure becomes smaller, the sealing valve 23 will deform toward the second chamber 221c side and thus leave the wall surface around the water inlet 221a, and the first chamber 221b is communicated with the water inlet 221a.

[0056] The swing arm 24 is pivotally connected to the mechanism main body 21. It is assembled between the mechanism main body 21 and the seat ring ear plate 11 and can swing reciprocally by a certain angle between the mechanism main body 21 and the seat ring ear plate 11. The swing direction is from the side of the mechanism main body 21 to the side of the seat ring ear plate 11 and from the side of the seat ring ear plate 11 to the side of the mechanism main body 21. The swing arm 24 is connected to the seat ring ear plate 11 through a linkage structure and can be driven to swing by the rotatable seat ring ear plate 11. The linkage structure can adopt two engaged tooth blocks with concavities and convexities. The two tooth blocks are respectively installed on the seat ring ear plate 11 and the swing arm 24. When the concave parts and convex parts of the two tooth blocks are engaged, the swing arm 24 remains in the initial state. When the convex parts of the two tooth blocks are abutted, the swing arm 24 is in the swing state. Of course, the linkage structure can also adopt a combination of a guiding groove and a guiding post with concavities and convexities. The guiding groove and the guiding post are respectively arranged on the seat ring ear plate 11 and the swing arm 24. The guiding post is slidably connected to the guiding groove and will not disengage, for example, adopting a T-shaped structure. When the end of the guiding post is in the concave area of the guiding groove, the swing arm 24 remains in the initial state. When the end of the guiding post is in the convex area of the guiding groove, the swing arm 24 is in the swing state.

[0057] The plug cap 25 can be a rubber plug. It is arranged at one end of the swing arm 24 and faces the pressure relief hole 213. When the swing arm 24 is in the initial state, the plug cap 25 blocks the pressure relief hole 213. At this time, water begins to accumulate in the second chamber 221c until the water pressure in the second chamber 221c is equal to the water pressure at the water inlet 221a. Then, the sealing valve 23 will deform towards the side of the water inlet 221a and thus make sealing contact with the wall surface around the water inlet 221a, disconnecting the first chamber 221b from the water inlet 221a. When the swing arm 24 is in the swing state, the plug cap 25 leaves the pressure relief hole 213. At this time, the second chamber 221c begins to drain water. Since the water pressure in the second chamber 221c is less than the water pressure at the water inlet 221a, the sealing valve 23 will deform towards the side of the second chamber 221c and thus separate from the wall surface around the water inlet 221a, connecting the first chamber 221b to the water inlet 221a.

[0058] Based on the above, the seat ring assembly provided by the present utility model can achieve:

[0059] When the seat ring 1 is in a certain state, for example, when the seat ring 1 is in the closed state and / or the fully open state, the swing arm 24 is in the initial state, the plug cap 25 blocks the pressure relief hole 213, and the sealing valve 23 adheres to the wall surface around the water inlet 221a of the cover 22, thereby disconnecting the water path between the water inlet pipe 222 and the water outlet pipe 223, and the pre-rinse nozzle 6 does not discharge water. When the seat ring 1 is in another state, for example, when the seat ring 1 rotates and switches from the closed state to the fully open state, or when the seat ring 1 rotates and switches from the fully open state to the closed state, the swing arm 24 is driven to swing by a certain angle, the plug cap 25 opens the pressure relief hole 213, and the sealing valve 23 leaves the wall surface around the water inlet 221a of the cover 22, thereby conducting the water path between the water inlet pipe 222 and the water outlet pipe 223, and the pre-rinse nozzle 6 starts to discharge water to wet the rear side wall surface of the toilet bowl 31.

[0060] In summary, a seat ring assembly provided by the present utility model can correspondingly control the switch of the water path control mechanism 2 when the seat ring 1 rotates, thereby controlling the supply or stop of water to the pre-rinse nozzle 6. There is no need for the user to manually operate the switch of the water path control mechanism 2, which improves the user experience. The seat ring assembly adopts a pure mechanical structure and has a long service life.

[0061] In one embodiment, as Figures 4 - 9 shown, an elastic element 26 is connected between the other end of the swing arm 24 and the mechanism main body 21. When the elastic element 26 is in the initial state, the plug cap 25 closes the pressure relief hole 213.

[0062] In this embodiment, an elastic element 26 is provided at the end of the swing arm 24 far from the plug cap 25. The elastic element 26 can be selected from a spring, a spring sheet, etc. The elastic element 26 is connected to the mechanism main body 21 and is used to support the other end of the swing arm 24. When the swing arm 24 is in the initial state, the elastic element 26 is also in the initial state and applies a force towards the seat ring ear plate 11 direction to the other end of the swing arm 24, so that the end of the swing arm 24 with the plug cap 25 approaches or adheres tightly to the connecting seat 212, and the plug cap 25 blocks the pressure relief hole 213.

[0063] In one embodiment, as Figures 4 - 9 shown, a first guiding structure 112 is provided on the side of the seat ring ear plate 11 facing the mechanism main body 21, and a second guiding structure 27 that is slidably matched with the first guiding structure 112 is provided at the other end of the swing arm 24. The first guiding structure 112 and / or the second guiding structure 27 is arc-shaped.

[0064] In this embodiment, in order to guide the cooperation between the swing arm 24 and the seat ring ear plate 11, a first guiding structure 112 and a second guiding structure 27 are configured. In one solution, the first guiding structure 112 can be an arc-shaped guiding groove; the second guiding structure 27 is a guiding element, for example, a guiding column, a guiding pin, etc. In another solution, the first guiding structure 112 is a guiding element, for example, a guiding column, a guiding pin, etc.; the second guiding structure 27 can be an arc-shaped guiding groove. The central angle, length, etc. of the guiding groove are set according to the parameters of the rotation and opening / closing of the seat ring 1.

[0065] The cooperation between the second guiding structure 27 and the first guiding structure 112 can achieve that during the rotation of the seat ring ear plate 11, the second guiding structure 27 remains in contact with the first guiding structure 112, improving the assembly stability of the two.

[0066] In one of the embodiments, as Figures 4 - 9 shown, the first guiding structure 112 includes an arc-shaped guiding groove 1121, and the guiding groove 1121 includes a deep groove section 1121a and a shallow groove section 1121b.

[0067] The second guiding structure 27 includes a guiding member 271 extending towards the guiding groove 1121, and the guiding member 271 is in clearance fit in the guiding groove 1121.

[0068] Wherein, when the guiding member 271 is in the deep groove section 1121a, the plug cap 25 closes the pressure relief hole 213, and when the guiding member 271 is in the shallow groove section 1121b, the plug cap 25 opens the pressure relief hole 213.

[0069] In this embodiment, the aforementioned linkage structure is integrated into the first guiding structure 112 and the second guiding structure 27. Specifically, the first guiding structure 112 includes an arc-shaped guiding groove 1121, and the length, central angle, etc. of the guiding groove 1121 are set according to the parameters of the rotation and opening / closing of the seat ring 1. The guiding groove 1121 includes a deep groove section 1121a and a shallow groove section 1121b, which are the aforementioned concave and convex surfaces. The lengths of the deep groove section 1121a and the shallow groove section 1121b are determined according to which stage of the product requires the pre-rinse nozzle 6 to be switched on or off.

[0070] The second guiding structure 27 includes a guiding member 271, such as a guiding column or a guiding pin. The guiding member 271 is arranged on the outer side of the other end of the swing arm 24, extends towards the guiding groove 1121, and is in clearance fit with the guiding groove 1121.

[0071] When the guiding member 271 is in the deep groove section 1121a, the swing arm 24 is in the initial state, and the plug cap 25 closes the pressure relief hole 213. When the guiding member 271 is in the shallow groove section 1121b, the swing arm 24 is in the swinging state, and the plug cap 25 opens the pressure relief hole 213.

[0072] In one of the embodiments, asFigure 3 and Figure 5 As shown in Figure 5 , the guiding groove 1121 includes a deep groove section 1121a, a shallow groove section 1121b, and a deep groove section 1121a that are connected in sequence.

[0073] When the guiding member 271 is in one of the deep groove sections 1121a, the seat ring 1 is in a closed state. When the guiding member 271 is in the other deep groove section 1121a, the seat ring 1 is in a fully open state.

[0074] In this embodiment, the guiding groove 1121 is composed of two deep groove sections 1121a and one shallow groove section 1121b, and the two deep groove sections 1121a are connected to both ends of one shallow groove section 1121b.

[0075] Thus, when the seat ring 1 is in a closed state and when the seat ring 1 is in a fully open state, the swing arm 24 is in an initial state, the plug cap 25 closes the pressure relief hole 213, and the pre-rinse nozzle 6 does not spray water. During the process of the seat ring 1 flipping open and closed, it indicates that the user is about to use the toilet or has already finished using the toilet, then the swing arm 24 is in a swinging state, the plug cap 25 opens the pressure relief hole 213, and the pre-rinse nozzle 6 performs a water spraying operation.

[0076] In one of the embodiments, as Figure 5 and Figures 8 - 10 shown, a guiding post 214 extending towards the cover 22 is provided on the mechanism main body 21, and the sealing valve 23 is slidably assembled on the guiding post 214 to guide the movement and deformation of the sealing valve 23.

[0077] Preferably, the guiding post 214 passes through the water flow hole 231. The aperture of the water flow hole 231 is larger than the diameter of the guiding post 214, and there is a certain gap for water flow, which can not only prevent excessive water flow but also achieve the assembly with the guiding post 214, simplifying the structure.

[0078] In one of the embodiments, as Figures 10 - 11 shown, a sealing flange 224 is provided on the edge of the water inlet 221a of the cover 22. When the pressure relief hole 213 is in an open state, the sealing valve 23 is closely attached to the sealing flange 224, improving the sealing effect between the end face of the sealing valve 23 and the wall surface around the water inlet 221a to better disconnect the water path between the water inlet pipe 222 and the water outlet pipe 223.

[0079] In one of the embodiments, as Figure 7 and Figure 9 shown, two mounting ear plates 215 arranged at intervals up and down are provided on one side of the mechanism main body 21, and the swing arm 24 is installed between the two mounting ear plates 215 through a pivot shaft 28.

[0080] In this embodiment, the swing arm 24 is assembled with a clearance between the upper and lower mounting lugs 215, which can prevent the swing arm 24 from shaking up and down or shifting, thus improving the assembly stability. Through holes are provided on the mounting lugs 215 for the pivot shaft 28 to pass through and connect.

[0081] In one embodiment, as Figure 7 and Figure 9 shown, the pivot shaft 28 is at one end close to the plug cap 25, which can provide a greater force for the end where the plug cap 25 is located, thereby blocking the pressure relief hole 213.

[0082] As Figures 12 - 13 shown, a toilet provided by an embodiment of the present invention includes a toilet body 3, a mounting seat 4, a pre-rinse nozzle 6, and the seat ring assembly described in any of the foregoing embodiments.

[0083] The mounting seat 4 is installed at the rear end of the toilet body 3. The seat ring 1 is pivotally connected to the mounting seat 4.
