Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an intelligent water-saving toilet seat mechanism, including a fixed base 1. The fixed base 1 is integrally injection molded from high-strength ABS engineering plastic, and the bottom is provided with bolts adapted to the mounting holes of the toilet body for a stable connection between the entire mechanism and the toilet. The surface of the fixed base 1 is provided with a lifting flushing component 2, which is the core component for achieving precise flushing and water-saving functions. The flushing height can be adjusted according to usage needs to improve flushing efficiency. The lifting flushing component 2 includes a limit frame 21, which is a U-shaped aluminum alloy frame structure with good guiding and load-bearing performance. The outer wall of the limit frame 21 is fixedly connected to... On the outer surface of the fixed base 1, an electric lifting shower head 22 is slidably connected to the inner side of the limiting frame 21. The inner side of the limiting frame 21 is provided with a guide rail that matches the slider of the shower head, ensuring a smooth and uninterrupted lifting process. The electric lifting shower head 22 consists of an electric telescopic rod, a shower head, and a lifting slide. The electric telescopic rod is driven by a DC servo motor, with a positioning accuracy of ±1mm. The shower head has multiple water outlets, allowing switching between pulse and gentle rinsing modes. An electric heated toilet seat 3 and a toilet lid 4 are movably hinged to the upper surface of the fixed base 1. The hinge uses a damping hinge structure, allowing for suspension at any angle. Stop. The electric heated toilet seat 3 has a built-in carbon fiber heating wire and temperature sensor, supporting multi-level temperature control from 30-40℃. Mounting seats 5 are fixedly connected to both sides of the upper surface of the fixed base 1. The mounting seats 5 are made of reinforced nylon material and have internal wiring channels for connecting the circuits of various components. There are two mounting seats 5, which are mirror images of each other along the central axis of the upper surface of the fixed base 1. This mirror image arrangement ensures balanced force on both sides, improves overall structural stability, and is ergonomically designed. A protective component 6 is provided on the mounting seat 5. The protective component 6 is mainly used to assist the elderly, children, and other users, preventing falls when getting up or sitting down. 6 includes a first safety armrest 61 and a second safety armrest 62. Both safety armrests adopt an arc-shaped design and are covered with an anti-slip rubber sleeve on the outer wall to improve grip comfort and safety. The bottom ends of the first safety armrest 61 and the second safety armrest 62 are fixedly connected to the upper surface of the two mounting bases 5 respectively, and are fastened with pre-embedded nuts and bolts. They can withstand a load-bearing pressure of not less than 100kg. The inner surface of the first safety armrest 61 is fixedly connected to a controller panel 63. The controller panel 63 integrates touch buttons and an LED display screen, which can adjust parameters such as washing mode, water temperature, and seat temperature, and also has a fault alarm function.

[0033] Reference Figure 1 , Figure 2 and Figure 4The mounting base 5 is equipped with a disinfection component 7, which automatically disinfects the inside of the toilet and the surface of the seat, improving hygiene and safety. The disinfection component 7 includes a mounting groove 71 and a liquid storage tank 76. The mounting groove 71 accommodates the rotating sprayer 72, and the liquid storage tank 76 stores disinfectant liquid. The two are connected by a pipeline to form a liquid supply circuit. The mounting groove 71 is located on the inner surface of the mounting base 5, and the outer wall of the liquid storage tank 76 is fixedly connected to the outer surface of the mounting base 5. The liquid storage tank 76 is made of transparent PP material, allowing for easy observation of the remaining disinfectant liquid. Its 500ml capacity is sufficient for 30 uses. For multiple disinfection needs, a rotary sprayer 72 is rotatably connected to the inner side of the mounting groove 71. The rotary sprayer 72 is made of stainless steel and can achieve large-amplitude rotary spraying to ensure full coverage of the disinfection area. A drive motor 73 is fixedly connected between the bottom end of the rotary sprayer 72 and the lower surface of the mounting base 5. The drive motor 73 drives the rotary sprayer 72 to rotate and uniformly rotate to disinfect the surface of the electric toilet seat 3. A first atomizing nozzle 74 is fixedly connected to the lower surface of the rotary sprayer 72. The first atomizing nozzle 74 is designed with high-pressure atomization, which can atomize the disinfectant into tiny particles of 5-10μm, improving the disinfection effect. As a result, multiple first atomizing nozzles 74 are evenly spaced along the length of the rotary sprayer 72. This even spacing ensures uniform spraying, with a 2cm distance between adjacent nozzles, covering all areas without dead zones. A second atomizing nozzle 75 is fixedly connected to the end of the rotary sprayer 72 furthest from the mounting base 5. The second atomizing nozzle 75 is positioned towards the central axis of the toilet bowl and is specifically designed for disinfection of the toilet seat surface and interior. A liquid pump 77 is fixedly connected to the bottom of the liquid storage tank 76. The liquid pump 77 is a miniature high-pressure diaphragm pump with a working pressure of 0.3-0.5MPa, capable of stably delivering disinfectant to the rotary sprayer 72 and the liquid storage tank. A liquid filling cap 79 is movably attached to the upper surface of tank 76. The liquid filling cap 79 adopts a threaded sealing design and is equipped with a silicone sealing ring to prevent disinfectant evaporation and leakage. It is easy to open. The top of the liquid pump 77 is connected to the bottom of the inner wall of the storage tank 76 through a suction pipe. The suction pipe is made of corrosion-resistant silicone tubing and has a filter head at the end to prevent impurities from entering the liquid pump 77 and causing blockage. A telescopic liquid supply pipe 78 is fixedly connected between the bottom of the liquid pump 77 and the inner side of the rotary sprayer 72. The telescopic liquid supply pipe 78 is a metal corrugated pipe structure that can freely extend and deform with the rotation of the rotary sprayer 72, while ensuring the sealing of the liquid supply channel.

[0034] Working principle: The mechanism of this intelligent water-saving toilet seat achieves a stable assembly with the toilet body through the fixed seat 1. Each functional component works together with the fixed seat 1 as the installation base. The whole is based on the controller panel 63 on the first safety handrail 61 as the core control unit, forming a complete workflow of "preparation-use-disinfection".

[0035] Before use, users can preset the temperature of the heated toilet seat 3 via the touch button on the controller panel 63. The built-in carbon fiber heating wire stabilizes the seat temperature at the target level of 30-40℃ under the monitoring of the temperature sensor. At the same time, the first safety armrest 61 and the second safety armrest 62 on the two mounting bases 5, which are symmetrically distributed along the central axis of the fixed base 1, can provide grip support, making it convenient for the elderly, children and other people to sit down steadily.

[0036] During use, if rinsing is required, after sending a command through the controller panel 63, the limit frame 21 in the lifting and rinsing assembly 2 will provide guidance for the electric lifting shower head 22. The electric telescopic rod drives the shower head to rise and fall precisely along the guide rail inside the limit frame 21 until it reaches the appropriate height. Then the rinsing shower head can switch between pulse or gentle rinsing modes as needed to achieve precise water-saving rinsing.

[0037] After use, the user triggers the disinfection command, and the disinfection component 7 is immediately activated: the disinfectant in the storage tank 76 is drawn by the micro high-pressure diaphragm pump through the suction tube, and is delivered to the rotary sprayer 72 in the installation groove 71 through the telescopic liquid supply pipe 78 made of metal corrugated material. At the same time, the drive motor 73 drives the rotary sprayer 72 to achieve a large-amplitude rotation. Multiple first atomizing nozzles 74 evenly distributed on the lower surface spray towards the surface of the electric heated toilet seat 3, while the second atomizing nozzle 75 at the end of the rotary sprayer 72 sprays evenly inside the toilet, achieving full coverage disinfection of the seat and the inside of the toilet.

[0038] After disinfection is completed, the telescopic liquid supply pipe 78 returns to its original position along with the rotating sprayer 72, the liquid pump 77 stops working, and the liquid filling cap 79 prevents the remaining disinfectant in the storage tank 76 from evaporating. Throughout the process, the electric heated toilet seat 3 and toilet lid 4 connected by the damping hinge can be suspended at any angle, and the safety handrail fixed by the pre-embedded nut can withstand a load of not less than 100kg, ensuring the balance between ease of use and safety.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
