Seat ring shaft hole switching pipeline and intelligent closestool

Abstract

The utility model provides a seat ring shaft hole switching pipeline and an intelligent closestool. The pipeline comprises a water supply valve, a seat ring switching device and a control valve which are connected in sequence. And the water supply valve, the seat ring switching device and the control valve are communicated through pipelines. The seat ring switching device comprises a connecting piece fixed to the base and a rotating piece connected with the connecting piece in a circumferential rotating mode, the rotating piece is arranged at the position of a shaft hole formed in the seat ring in a penetrating mode, and the rotating piece and the seat ring rotate synchronously. The seat ring switching device is provided with a through water passing channel in the axial direction of the seat ring switching device, and the water passing channel is communicated with pipelines in the seat ring and the base. The control valve is arranged in the containing cavity of the seat ring and used for controlling on-off or switching of the pipeline. The mode that a traditional water inlet pipe twists along with the seat ring is ingeniously converted into the mode that the rotating body rotates relative to the connecting body at the hinged position of the seat ring and the base, and therefore the problem that the water inlet pipe rubs against the inner wall of the shaft hole is avoided, and the situation that the seat ring is difficult to turn over due to the fact that the bending resistance of the water inlet pipe with high hardness is large is avoided.

Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a seat ring shaft hole adapter pipe and a smart toilet. Background Technology

[0002] In the design of modern sanitary equipment, toilets, as an indispensable facility in daily life, have seen innovative designs that integrate the switch knob onto the seat, enhancing ease of use and providing a more user-friendly operating experience. However, while bringing convenience, this design also introduces a series of technical challenges, particularly in the integration of the seat and the water passage.

[0003] Specifically, when the toilet seat knob is integrated into the seat ring, a corresponding water passage must be installed inside the seat ring to connect the water source and the switching mechanism in order for the switching function to operate properly. This design has encountered two major challenges in practical applications:

[0004] Water pipe wear: Because the toilet seat needs to be frequently rotated during daily use, if the water pipe is directly connected to the rotating part of the seat, each rotation of the seat will cause the water pipe to move as well. This continuous mechanical movement not only accelerates the physical wear of the water pipe but may also cause safety hazards such as leaks due to long-term friction, thus significantly reducing the service life of the water pipe. This is clearly unacceptable for sanitary ware designs that aim for long-term stable operation and reduced maintenance costs.

[0005] Issues with seat rotation: On the other hand, considering that some water pipes may need to be directly connected to the water inlet pipe to withstand high water pressure, these pipes are usually made of high-pressure resistant materials, which are highly rigid but have poor bending performance. During the seat rotation process, these rigid pipes may not be able to follow the seat's movement trajectory due to the high bending resistance, resulting in poor seat rotation and potentially damaging the pipes or seat structure due to excessive stress. This not only affects the user experience but may also pose a threat to the overall structural safety of the toilet.

[0006] In conclusion, while the existing toilet seat switch knob design on the seat ring offers operational convenience, it has significant technical shortcomings in the integration of the water passage and the seat ring. There is an urgent need for a new design solution that can address the issues of water pipe wear and poor seat ring rotation. Utility Model Content

[0007] To address the aforementioned issues, the purpose of this invention is to provide a seat ring shaft hole adapter pipe and a smart toilet. By setting up a seat ring adapter device, the problems of water pipe wear and seat ring rotation caused by the traditional toilet seat switch knob design on the seat ring are solved.

[0008] This utility model is achieved through the following technical solution:

[0009] A toilet seat shaft hole adapter pipe, with at least part or all of the pipes located in the toilet seat, includes a water supply valve, a toilet seat adapter, and a control valve connected in sequence; the water supply valve, the toilet seat adapter, and the control valve are connected by pipes.

[0010] The water supply valve is installed on the base of the toilet seat and is used to connect to a water source.

[0011] The toilet seat includes a seat ring, which is hinged to the base of the toilet seat; the seat ring adapter is provided at the hinge between the seat ring and the base, and the hinge is provided with a shaft hole through which the seat ring passes.

[0012] The seat ring adapter includes a connector fixed on the base and a rotating component rotatably connected to the connector. The rotating component passes through a shaft hole on the seat ring and rotates synchronously with the seat ring. The seat ring adapter has a through water passage along its axial direction, and the water passage is connected to the pipes in the seat ring and the base respectively.

[0013] The control valve is located within the receiving cavity of the seat ring and is used to control the on / off or switching of the pipeline.

[0014] Furthermore, the transfer pipeline also includes an execution component, which is mounted on the base of the toilet seat. The inlet of the water passage is connected to the outlet of the water supply valve through a first inlet pipe, and the outlet of the water passage is connected to the inlet of the control valve through a second inlet pipe. The outlet of the control valve is connected to the execution component through at least one outlet pipe.

[0015] Furthermore, the first water inlet pipe is located on the base of the toilet seat, the second water inlet pipe is located in the receiving cavity of the seat ring, one end of the water outlet pipe is located in the receiving cavity of the seat ring and connected to the outlet of the control valve, and the other end passes through the shaft hole of the seat ring, extends into the base, and is connected to the actuation component.

[0016] Furthermore, the distance between the seat ring adapter and the water supply valve is less than the distance between the seat ring adapter and the actuator or control valve; the distance between the water outlet of the water supply valve and the water inlet of the seat ring adapter is less than the distance between the water outlet of the water supply valve and the water outlet of the seat ring adapter.

[0017] Furthermore, the base includes a fixed seat and a rear shell, the rear shell is provided with a mounting hole, the water supply valve is installed at the mounting hole, and the actuation component is installed on the fixed seat; the water supply valve is a pressure stabilizing valve, the actuation component is a water spray body for washing the human body; the control valve is a switching valve or an on / off valve.

[0018] Furthermore, the toilet seat base is provided with a clamp for holding the water outlet pipe, and the clamp is located between the shaft hole and the actuating component; the length of the portion of the water outlet pipe located between the shaft hole and the clamp is greater than the maximum straight-line distance between the shaft hole and the clamp during the rotation of the seat ring.

[0019] Furthermore, the seat ring is provided with at least one set of limiting ribs, which are located at the shaft hole to clamp the water outlet pipe and the second water inlet pipe.

[0020] Furthermore, the hardness of the first inlet pipe is greater than or equal to the hardness of the second inlet pipe, which is greater than the hardness of the outlet pipe. The first and second inlet pipes are made of rigid pipes, while the outlet pipe is made of flexible pipe.

[0021] Furthermore, the outer wall of the rotating component is provided with a limiting groove along its axial direction, and the limiting groove and the inner wall of the shaft hole together form a pipe passage.

[0022] A smart toilet includes the aforementioned seat ring shaft hole adapter pipe.

[0023] Compared with the prior art, the technical solution of this utility model and its beneficial effects are as follows:

[0024] (1) The seat ring shaft hole adapter pipe of this utility model is provided with a seat ring adapter device at the hinge of the seat ring and the base, which divides the water inlet pipe between the water supply valve and the control valve into two sections. The water inlet pipe between the water supply valve and the seat ring adapter device is connected to the connector fixed on the base, and the water inlet pipe between the seat ring adapter device and the control valve is connected to the rotating part that rotates with the seat ring. The two sections of water inlet pipe are connected through the water passage on the seat ring adapter device. This cleverly transforms the traditional method of the water inlet pipe following the rotation of the seat ring into the rotation of the rotating body relative to the connector during the rotation of the seat ring. The two sections of water inlet pipe themselves remain relatively stationary with their carrier and will not be displaced, thereby avoiding the problem of friction between the water inlet pipe and the inner wall of the shaft hole, and avoiding the difficulty of seat ring flipping caused by the large bending resistance of the water inlet pipe with high hardness.

[0025] (2) The toilet seat base of this utility model is provided with a pipe clamp for holding the water outlet pipe, which makes the arrangement of the water outlet pipe more orderly. The pipe clamp is located between the shaft hole and the actuator, which reduces the movable part of the water outlet pipe to between the shaft hole and the pipe clamp, thereby ensuring the stability of the connection between the water outlet pipe and the actuator.

[0026] (3) The outer wall of the rotating part of this utility model is provided with a limiting groove along its axial direction. The limiting groove and the inner wall of the shaft hole form a pipe passage for the water outlet pipe to pass through, preventing the water outlet pipe from being squeezed or rubbed by the outside during the rotation of the seat ring. At the same time, the limiting groove forms a clearance space, making the layout of the water inlet pipe inside the seat ring more neat and orderly, improving the space utilization rate, and contributing to the compactness of the overall structure of the toilet.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] See Figure 1 A seat ring shaft hole adapter pipeline includes a water supply valve 100, a seat ring adapter 300, and a control valve 500 connected in sequence. The water supply valve 100, the seat ring adapter 300, and the control valve 500 are connected by pipelines. In this embodiment, the outlet of the water supply valve 100 is connected to the inlet of the seat ring adapter 300 through a first inlet pipe 200, the outlet of the seat ring adapter 300 is connected to the inlet of the control valve 500 through a second inlet pipe 400, and the outlet of the control valve 500 is connected to a subsequent actuator 7 (e.g., a water spray body) through an outlet pipe 600.

[0044] See Figure 2 and Figure 3 The water supply valve 100 is used to connect to a water source and is mounted on the base of the toilet seat. In this embodiment, the base of the toilet seat is a single unit fixedly mounted on the ceramic surface. The base includes a fixing seat (not shown) and a rear shell 2. The actuating component 7 is disposed within the fixing seat, and the rear shell 2 has mounting holes at which the water supply valve 100 is mounted. In other embodiments, the fixing seat of the toilet seat can also be the toilet itself, allowing the water supply valve 100 to be directly mounted on the ceramic surface of the toilet.

[0045] The toilet seat also includes a seat ring 1, which is hinged to the base of the toilet seat. Specifically, the seat ring 1 is hinged to the back cover 2 and can be flipped relative to the back cover 2. A seat ring adapter 300 is provided at the hinge point between the seat ring and the base, and a shaft hole 300 through which the seat ring 1 passes is provided at the hinge point.

[0046] See Figures 4 to 6The seat ring adapter 300 includes a connector 310 fixed to the base and a rotating member 320 rotatably connected to the connector 310. The connector 310 is fixed to the rear shell 2, and the rotating member 320 passes through the shaft hole 3 opened on the seat ring 1. The rotating member 320 rotates synchronously with the seat ring 1. The seat ring adapter 300 has a through water passage 330 along its axial direction. The water passage 330 can be a through hole for water passage that passes through the connector and the rotating member in sequence. The opening formed by the water passage 330 on the side of the connector is the water inlet of the seat ring adapter 300, and the opening formed by the water passage 330 on the side of the rotating member is the water outlet of the seat ring adapter 300. The inlet of the water passage 330 is connected to the outlet of the water supply valve 100 through the first inlet pipe 200, and the outlet of the water passage 330 is connected to the inlet of the control valve 500 through the second inlet pipe 400; the outlet of the control valve 500 is connected to the actuator 700 through at least one outlet pipe 600.

[0047] The control valve 500 is used to control the on / off or switching of the pipeline. The control valve 500 is located within the receiving cavity of the seat ring 1. One end of the water outlet pipe 600 is located within the receiving cavity of the seat ring 1 and connected to the outlet of the control valve 500; the other end passes through the shaft hole 3 of the seat ring, extends into the rear housing, and continues to the fixed seat to connect with the actuator. It is understood that the control valve 500 is located within the receiving cavity of the seat ring 1, and the second water inlet pipe 400 connecting the rotating body 320 and the control valve 500 is located within the receiving cavity of the seat ring 1. The connecting member 310 and the water supply valve 100 are both located on the rear housing 2, and the first water inlet pipe 200 connecting the connecting member 310 and the water supply valve 100 is located within the rear housing. In this embodiment, the water supply valve 100 is a pressure regulating valve, the control valve 500 is a switching valve or on / off valve, and the actuator 700 is a water spray body used for washing the human body.

[0048] The seat ring adapter device ensures that the water pipe (first water inlet pipe 200) between the water inlet of the seat ring adapter device 300 and the water supply valve 100 remains stationary during the seat ring rotation process. The water pipe (second water inlet pipe 400) between the water outlet of the seat ring adapter device 300 and the control valve 500 rotates simultaneously with the rotating body 320 and the seat ring 1. The second water inlet pipe 400, the rotating body 320, and the seat ring 1 remain relatively stationary, avoiding the water pipe from moving directly with the seat ring during frequent rotation, thereby reducing the physical wear of the water pipe. At the same time, the water pipe follows the movement trajectory of the seat ring, avoiding the difficulty of seat ring rotation caused by the high bending resistance of the water pipe with high hardness.

[0049] In this embodiment, since the water inlet pipe will not interfere with the rotation of the seat ring, the first water inlet pipe 200 and the second water inlet pipe 400 can be made of pipes with higher hardness so as to withstand greater water pressure.

[0050] The distance between the seat ring adapter 300 and the water supply valve 100 is less than the distance between the seat ring adapter 300 and the actuator 700 or control valve 500, making the water supply valve 100 closer to the seat ring adapter 300, resulting in a more concentrated pipeline layout. The distance between the outlet of the water supply valve 100 and the inlet of the seat ring adapter 300 is less than the distance between the outlet of the water supply valve 100 and the outlet of the seat ring adapter 300, meaning the outlet of the water supply valve 100 is closer to the inlet of the seat ring adapter, further reducing the length of the first inlet pipe 200.

[0051] The outer wall of the rotating component 320 is provided with a limiting groove 321 along its axial direction. The limiting groove 321 and the inner wall of the shaft hole 3 enclose a pipe passage 340, through which the water outlet pipe 600 passes and extends into the base. The pipe passage 340 prevents the water outlet pipe 600 from being squeezed or rubbed by the outside during the rotation of the seat ring 1. At the same time, the limiting groove 321 provides clearance space, making the layout of the water outlet pipe 600 inside the seat ring more neat and orderly, improving space utilization and contributing to the compactness of the overall toilet structure. At least two limiting grooves 321 are provided, and the limiting grooves 321 are centrally symmetrically distributed with respect to the axis of the pipe passage.

[0052] The toilet seat base is equipped with a clamp 311 for holding the water outlet pipe 600. The clamp 311 is located between the shaft hole 3 and the actuator 700. In this embodiment, the clamp 311 is located inside the rear shell 2, which makes the arrangement of the water outlet pipe 600 more orderly. The part of the water outlet pipe 600 located inside the rear shell 2 is movable and rotates with the seat ring 1. The length of the part of the water outlet pipe 600 located between the shaft hole 3 and the clamp 311 is reserved to be greater than the maximum straight-line distance between the shaft hole 3 and the clamp 311 during the rotation of the seat ring. This allows the length of this part of the water outlet pipe 600 to adapt to the change in the maximum straight-line distance during the rotation of the seat ring, avoiding excessive stretching of the water outlet pipe 600 due to the rotation of the seat ring. By reducing the movable part of the water outlet pipe 600 to between the shaft hole 3 and the clamp 311, the stability of the connection between the water outlet pipe 600 and the actuator 700 is ensured.

[0053] In this embodiment, the outlet pipe 600 is made of flexible tubing. Firstly, the portion of the outlet pipe 600 located between the shaft hole 3 and the pipe clamp 311 is movable, and using a flexible tubing facilitates the movement of this portion of the outlet pipe 600 along with the seat ring 1. Secondly, after the water flows through the control valve 500, the water pressure inside the outlet pipe 600 is lower than that in the second inlet pipe 400, allowing for the selection of a softer pipe material. Therefore, the pipe hardness selection is: hardness of the first inlet pipe ≥ hardness of the second inlet pipe > hardness of the outlet pipe. The first and second inlet pipes are made of rigid pipes, while the outlet pipe is made of flexible tubing. In this embodiment, the rigid pipe is made of PVC, and the flexible tubing is made of silicone.

[0054] In this embodiment, the seat ring is provided with at least one set of limiting ribs for clamping the water outlet pipe 600 and the second water inlet pipe 400. The limiting ribs are located at the shaft hole 3, on the side of the seat ring 1 away from the connector 310, which makes the pipeline in the accommodating cavity of the seat ring 1 more compact and orderly. At the same time, it also makes the second water inlet pipe more firmly fixed at the shaft hole of the seat ring, preventing the second water inlet pipe from shaking or falling off the water outlet of the seat ring adapter during the rotation of the seat ring.

[0055] This embodiment also provides a smart toilet, including the aforementioned seat ring shaft hole adapter pipe, which solves the problems of water pipe wear and seat ring rotation difficulties caused by the traditional toilet seat switch knob design on the seat ring, and improves the performance, reliability and user experience of the smart toilet.

[0056] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
