[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a smart toilet with a water-saving, pressure-reducing, and noise-reducing valve, which has the following beneficial effects:

[0015] Intelligent water pressure adjustment reduces nighttime noise: The time-limited control module built into the pressure-reducing and noise-reducing valve can automatically distinguish between day and night. At night, it automatically switches to low-pressure mode to reduce the impact of water flow during flushing, effectively reducing flushing noise and avoiding disturbing family members' rest, especially protecting the sleeping environment of the elderly and infants.

[0016] The double-sealing design prevents water leakage: a double-sealing structure is formed between the cover and the groove through a first sealing ring and a second sealing ring. The first sealing ring wraps around the water inlet pipe, and the second sealing ring is located in the annular groove of the annular protrusion, fitting tightly with the annular limiting plate to ensure the sealing of the cover, avoid water leakage, and improve the reliability of the toilet.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please see Figures 1-4 The present invention relates to a smart toilet with a water-saving, pressure-reducing, and noise-reducing valve, comprising a smart toilet body 1, a hollow groove 2 at the rear end of the smart toilet body 1 and a water inlet pipe 3 located inside the hollow groove 2, a pressure-reducing and noise-reducing valve 4 fixed inside the hollow groove 2 on the water inlet pipe 3, and a time-period control module inside the pressure-reducing and noise-reducing valve 4.

[0024] The outer end of the empty groove 2 is provided with a cover 8, and the middle part of the cover 8 is provided with a through hole through which the water inlet pipe 3 passes. The inner wall of the through hole is provided with a first sealing ring 10 through which the water inlet pipe 3 passes.

[0025] The periphery of the slot 2 is provided with a plurality of positioning slots 6, and the inner wall of the positioning slot 6 is provided with a slot 7. The periphery of the cover 8 is provided with a plurality of positioning blocks 11 that are inserted into the positioning slot 6. The interior of the positioning block 11 is provided with a cavity 13, and the interior of the cavity 13 is provided with a spring. One end of the spring is provided with a locking block 12 that cooperates with the slot 7.

[0026] Multiple card blocks 12 are the same size and are all isosceles trapezoidal structures. Multiple handles 9 are provided on the cover 8 with symmetrical through holes.

[0027] When using this smart toilet equipped with a water-saving, pressure-reducing, and noise-reducing valve 4, the valve automatically identifies day and night times through its built-in time-slot control module. During nighttime hours (e.g., 10:00 PM to 6:00 AM), the time-slot control module activates a low-pressure mode, and the valve 4 adjusts the inlet water pressure to a suitable low-pressure state to reduce water flow impact noise during flushing. During daytime hours (e.g., 6:00 AM to 10:00 PM), it switches to a high-pressure mode to ensure sufficient flushing power.

[0028] When maintenance or repair of the inlet pipe 3 and the pressure reducing and noise reducing valve 4 is required, the operator can lift the cover 8 through the handle 9 on the cover 8. At this time, the locking block 12 on the positioning block 11 is squeezed by external force, compresses the spring and disengages from the locking groove 7. Then the locking block 12 retracts into the cavity 13, thereby separating the cover 8 from the cavity 2.

[0029] After maintenance, align the positioning block 11 of the cover 8 with the positioning slot 6 of the empty slot 2 and insert it. The locking block 12 will pop out under the action of the spring and lock into the slot 7, thus realizing the quick installation of the cover 8.

[0030] The outer wall of the cover 8 is tightly fitted with the inner wall of the slot 2. An annular limiting plate 5 is fixedly installed on the inner wall of the slot 2. An annular protrusion 14 penetrating the annular limiting plate 5 is provided on the inner side of the cover 8, and the outer wall of the annular protrusion 14 is tightly fitted with the inner wall of the annular limiting plate 5. An annular groove 15 is provided on the periphery of the annular protrusion 14, and a second sealing ring 16 is provided inside the annular groove 15.

[0031] Both the first sealing ring 10 and the second sealing ring 16 are made of rubber.

[0032] During installation, the annular protrusion 14 of the cover 8 passes through the annular limiting plate 5 in the slot 2, and the second sealing ring 16 in the annular slot 15 fits tightly against the inner wall of the annular limiting plate 5. At the same time, the first sealing ring 10 on the inner wall of the through hole wraps around the water inlet pipe 3. The double sealing structure prevents water leakage.

[0033] The cover 8 is connected to the slot 2 via a structure consisting of a positioning block 11, a locking block 12, and a spring. The locking block 12 is an isosceles trapezoid and automatically engages when inserted into the positioning slot 6. To disassemble, simply press the handle 9 to lift the cover 8, and the locking block 12 will retract under pressure. The operation is simple and convenient, facilitating the maintenance or replacement of the water inlet pipe 3 and the pressure reducing and noise reduction valve 4, thus reducing the difficulty of after-sales maintenance.

[0034] Pressure reducing and noise reduction valve 4: Grundfos RV-10 series and Rexroth ZDR6DP2-4X / 75YM solenoid relief valves are used.

[0035] Time period control module: Siemens S7-1200 series PLC (with clock module) and Arduino Uno development board (with DS1307 clock module).
