Description

A hinge shaft water pipe adapter for a single-cooled toilet seat and a toilet seat plate. Technical Field

[0001] This utility model relates to a hinge shaft water pipe adapter for a single-cooling toilet seat and a toilet seat. Background Technology

[0002] This single-cooling bidet toilet seat, requiring no external power supply and using a purely mechanical valve to switch between bidet and shower spray, is simple and hygienic to use, making it a popular and well-regarded bathroom product. For example, our company previously applied for a Chinese utility model patent (CN219109291). The flushing assembly integrated into the seat cover as disclosed in U) is a rigid pipe shaft designed to connect the seat and the rear shell to a tap water supply. Water is then routed to a control valve on the side of the seat via a rotatable fitting inside the seat hinge. The control valve connects to the bidet and feminine wash spray nozzles within the flushing assembly. While the control valve is conveniently located on the side of the seat with an exposed control knob, the integrated flushing assembly requires a convex design at the rear of the seat to accommodate the protruding bidet and feminine wash nozzles. This protrusion affects the overall appearance of the seat when it is flipped up. Furthermore, after using the toilet, performing bidet, or feminine wash, water splashed onto the outer wall of the spray nozzles may collect and flow back into the seat from the protruding part. In the humid conditions of a bathroom, this can lead to bacterial growth inside the seat, affecting its hygiene.

[0003] Therefore, the rinsing components for posterior and feminine washes need to be installed inside the rear shell of the seat cover. The main water inlet from the rear shell needs to pass through the hinge shaft to the seat ring and connect to the control valve. Then, the water pipe connected to the control valve in the seat ring passes back through the hinge shaft to the rear shell and connects to the posterior and feminine wash spray lines of the rinsing components. However, since the main water inlet pipe, which makes a near right-angle turn from the rear shell to the seat ring control valve, is made of PVC textile pipe, which is relatively hard, the main water inlet pipe forms a section that is almost parallel to the hinge shaft and a section that is perpendicular to the hinge shaft. When the seat ring is flipped, the section of the main water inlet pipe that is parallel to the hinge shaft will be twisted in the rotation direction. The strong torque generated will affect the smooth opening and closing of the seat ring. Therefore, it is necessary to eliminate or reduce the torque generated by the main water inlet pipe at the hinge shaft between the rear shell and the seat ring when the seat ring is flipped. Summary of the Invention

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] Referring to Figures 1, 5, and 6, a toilet seat includes a seat ring 20 and a back cover 10. A control valve mounting part 60 is provided on the seat ring 20, and a control valve (not shown in the figures) is installed inside the control valve mounting part 60. A spray washing device 30 is provided inside the back cover 10. The spray washing device 30 includes a posterior wash spray rod sleeve 31 and a feminine wash spray rod sleeve 32. The posterior wash spray rod sleeve 31 and the feminine wash spray rod sleeve 32 are respectively connected to a first flexible hose 80 and a second flexible hose 90. The other ends of the first flexible hose 80 and the second flexible hose 90 are connected to the control valve mounting part 60. A main water inlet pipe 70, located inside the back cover 10, is connected to the control valve mounting part 60. The other end of the main water inlet pipe 70 is connected to a water inlet adapter 100, which can be connected to tap water. The water circuits for the posterior wash and feminine wash spray rods are controlled by the control valve mounting part 60.

[0043] Referring to Figures 1-4, this utility model provides a hinge shaft water pipe adapter for hinged rear shell 10 and seat ring 20 for a single-cooling toilet seat cover. It includes an adapter rotating member 40 and an adapter fixing member 50 disposed within the rear end of the seat ring 20. The adapter rotating member 40 includes a bearing portion 41 sleeved within the seat ring shaft hole 21. The bearing portion 41 has a first pipe column 42 and a second pipe column 43 respectively disposed at both ends, communicating with each other. In this utility model, the main water inlet pipe 70 is divided into a main pipe shell inner section 71 and a main pipe ring inner section 72. The first pipe column 42 connects to the main pipe shell inner section 71 disposed within the rear shell 10. The other end of the main pipe shell inner section 71 is connected to and installed within the rear shell 10. The water inlet adapter 100 on the inner wall has a pair of clearance notches 45 on the bearing part 41. The clearance notches 45 are used to allow the first soft rubber tube 80 and the second soft rubber tube 90, which are connected to the buttock spray rod sleeve 31 and the feminine wash spray rod sleeve 32, to make way for each other. The first soft rubber tube 80 and the second soft rubber tube 90 pass through the clearance notches 45 and are connected to the control valve mounting part 60. The adapter fixing part 50 includes a socket 51 that is rotatably connected to the second tube column 43, and a third tube column 52 that is integrally formed with the socket 51 and is conductive. The third tube column 52 is used to connect to the inner section 72 of the main tube ring 20. The other end of the inner section 72 of the main tube ring is connected to the control valve mounting part 60.

[0044] The structure of each component of this utility model will be described below.

[0045] Referring to Figures 1, 5 to 7, in this embodiment, the control valve mounting part 60 protrudes from the left side wall of the seat ring 20, allowing the user to operate it with one hand, which conforms to the usage habits of most toilet users. In other embodiments, the control valve mounting part 60 is located on the right side wall of the seat ring 20 or on the front side wall, without further limitation.

[0046] Referring to Figures 1, 5, and 6, in this embodiment, the buttock wash spray bar sleeve 31 and the feminine wash spray bar sleeve 32 are arranged side by side in the middle of the rear shell 10, and the switching of the buttock wash and feminine wash spray bar water paths is realized by a control valve (not shown in the figure).

[0047] Referring to Figures 1 to 4, the adapter rotary member 40 also includes a limiting part 44 disposed on the bearing part 41 near the second tube column 43. The limiting part 44 presses against the inner wall of the seat ring 20. The limiting part 44 can prevent the adapter rotary member 40 from axially displacing during rotation, thus avoiding water leakage or structural loosening.

[0048] Referring to Figures 1 and 6, the adapter fixing component 50 is provided with an external protrusion 53, and the external protrusion 53 is provided with a positioning hole 531. A threaded post 22 is provided inside the seat ring 20. The threaded post 22 is set in the positioning hole 531 and is locked and fixed with a screw 23. The screw 23 locking structure ensures a stable connection between the adapter fixing component 50 and the seat ring 20, and prevents the component from falling off due to displacement caused by frequent flipping.

[0049] Referring to Figures 2 and 4, several sealing rings are provided on the first pipe column 42, the second pipe column 43, and the third pipe column 52. The sealing rings can effectively prevent leakage at the water pipe connections caused by rotation or vibration, ensuring the water system's airtightness.

[0050] Both the inner section 71 and the inner section 72 of the main pipe shell are PVC braided pipes. The purpose of using PVC braided pipes is to prevent the main inlet pipe 70 from bursting due to excessive water pressure, as municipal tap water pressure is relatively high and PVC pipes have good burst resistance. The first soft rubber tube 80 and the second soft rubber tube 90 are silicone tubes. Silicone tubes are relatively flexible, and during the process of the seat ring 20 flipping up or falling back, the torque generated by the first soft rubber tube 80 and the second soft rubber tube 90 at the hollow hinge shaft 11 is small and insufficient to affect the smooth opening and closing of the seat ring 20.

[0051] The working principle and specific implementation steps of this utility model are explained in detail below.

[0052] Referring to Figures 1, 5, and 6, the main water inlet pipe 70, which connects to the control valve mounting part 60 at a near right angle from the rear housing 10, is made of PVC braided tubing, which is relatively hard. The main water inlet pipe 70 forms a section that is almost parallel to the hinge shaft and a section that is perpendicular to the hinge shaft. When the seat ring 20 is flipped, the section of the main water inlet pipe 70 that is parallel to the hinge shaft will be twisted in the rotational direction. The strong torque generated will affect the smooth opening and closing of the seat ring 20. Therefore, it is necessary to eliminate or reduce the torque generated by the main water inlet pipe 70 at the hinge shaft of the rear housing 10 when the seat ring 20 is flipped.

[0053] The working principle of this utility model is as follows: A transition device is provided for hinged connection between the rear shell 10 and the rear seat 20. The transition device includes a transition rotating member 40 and a transition fixing member 50. The transition rotating member 40 is connected to the inner section 71 of the main pipe shell, and the transition fixing member 50 is connected to the inner section 72 of the main pipe ring. During the process of the seat ring 20 flipping up or falling down, the transition fixing member 50 rotates relative to the seat ring 20, and the transition rotating member 40 rotates relative to the transition fixing member 50, which can eliminate the torque generated by the main water inlet pipe 70 at the seat ring shaft hole 21.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
