[0019] 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. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Reference Figure 1 As shown, a self-generating smart toilet based on a pressure water tank includes: Pressure tank 1, which is used to store the water required for flushing and to provide flushing pressure; Water supply line 2, one end of which is connected to an external water source, and the other end of which is connected to the water storage chamber; A flushing water passage 3 is provided, with one end connected to the water storage chamber and the other end corresponding to the flushing area of ​​the toilet body 4. This passage is used to transport water from the pressure tank 1 to the toilet body 4 for flushing. It also includes a self-generating device 7, which includes a generator and an impeller. The impeller is connected to the generator in a transmission manner. The impeller is located in the water supply channel 2 and / or the flushing channel 3. The water impacts the impeller and drives it to rotate. The impeller drives the generator to operate in order to generate electricity. It also includes an energy storage module 5, the output end of the generator is electrically connected to the energy storage module 5, and is used to transmit the electrical energy generated by the generator to the energy storage module 5 for storage; The controller 6 has its power input terminal electrically connected to the energy storage module 5, and its signal receiving terminal electrically connected to the sensing probe 9 to receive flushing signals, including flushing signals indicating that the user has finished using the water or pre-flushing signals. The controller 6 has its signal output terminal electrically connected to the electrically controlled valve 8 located in the flushing water path 3. The electrically controlled valve 8 responds to the control commands output by the controller 6 to control the shut-off or opening of the flushing water path 3.

[0021] The impeller is located in the water supply channel 2 and / or flushing channel 3. It generates electricity by utilizing the inherent water flow during the replenishment and / or flushing stages of the pressure water tank 1. It can convert the kinetic energy of water into electrical energy without consuming additional energy. The electrical energy generated by the generator is stored in the energy storage module 5, and then provides stable power to load components such as the controller 6, the electric control valve 8, and the induction probe 9, without the need to connect to the mains power.

[0022] The sensor probe 9 is used to receive flushing signals in real time. After the user leaves the seat, the controller 6 automatically outputs a command to control the electric control valve 8 to open the flushing water path 3. There is no need to manually press the flush button, avoiding hand contact with bacteria and significantly improving hygiene. At the same time, it eliminates the problem of bathroom odor and dirt residue caused by forgetting to flush.

[0023] The energy storage module 5 includes a supercapacitor 51, and the electrical energy generated by the generator is instantly charged to the supercapacitor 51. The supercapacitor 51 has second-level fast-charging characteristics. Due to the impact of water flow, the self-generating device 7 experiences short-term peaks in its output current. However, the battery 52, limited by its chemical properties, cannot quickly absorb these peak energy spikes. This invention utilizes the supercapacitor 51 to capture and store these instantaneous energy spikes immediately, maximizing the capture of these peak energy spikes and reducing energy waste. For example, the supercapacitor 51 can completely absorb the 3mWh peak energy generated within the first 2 seconds of flushing the waterway 3. If the battery 52 were directly charged, only 1mWh would be absorbed, with the remaining 2mWh wasted. This step can recover twice the peak energy.

[0024] The energy storage module 5 also includes a battery 52. ​​The supercapacitor 51 slowly charges the energy to the battery 52. ​​The battery 52 is connected to the power input terminal of the controller 6. The battery 52 is preferably an energy storage battery, such as a lithium-ion battery in the prior art. It utilizes the characteristics of long-term energy storage and stable energy output to provide stable power to load components such as the sensing probe 9 in standby mode. The battery 52 also avoids the battery from self-discharging too quickly.

[0025] In a first embodiment of the self-generating device 7, a single impeller can be installed in either the water supply path 2 or the flushing path 3, and a single generator can be connected to the impeller. During flushing or water supply, the water flow drives the impeller to rotate, and the impeller then drives the generator to generate electricity.

[0026] As a second embodiment of the self-generating device 7, refer to Figure 3As shown, the self-generating device 7 includes a first impeller 71, a second impeller 73, and a dual-head generator. The dual-head generator has two coaxial and oppositely arranged power input shafts. The first impeller 71 is fixedly connected to the front input shaft of the dual-head generator, and the second impeller 73 is fixedly connected to the rear input shaft of the dual-head generator. The first impeller 71 is installed in the pipe section of the water supply channel 2, and its blade orientation is adapted to the water flow direction of the water supply channel 2. The second impeller 73 is installed in the pipe section of the flushing water channel 3, and its blade orientation is adapted to the water flow direction of the flushing water channel 3. During operation, when the water supply channel 2 is in the water supply state, the water flow impacts the first impeller 71 along the water supply direction, causing it to rotate at high speed. The first impeller 71 drives the dual-head generator 72 to generate electricity through the front input shaft. When the flushing water channel 3 is in the flushing state, the water flow impacts the second impeller 73 along the flushing direction, causing it to rotate. The second impeller 73 drives the dual-head generator 72 to generate electricity through the rear input shaft.

[0027] As a third embodiment of the self-generating device 7, refer to Figure 1 As shown, the self-generating device 7 includes a first impeller 71, a first generator 72, a second impeller 73, and a second generator 74. The first impeller 71 is fixed inside the pipe of the water supply channel 2, with its blades oriented in the same direction as the water flow in the water supply channel 2. The first impeller 71 is connected to the input shaft of the first generator 72 via a drive shaft. The second impeller 73 is coaxially fixed inside the pipe of the flushing water channel 3, with its blades oriented in the same direction as the water flow in the flushing water channel 3. The second impeller 73 is connected to the input shaft of the second generator 74 via a drive shaft.

[0028] The first generator 72 is fixed to the outer wall of the water supply pipe 2, and the second generator 74 is fixed to the outer wall of the flushing water pipe 3. The output terminals of the first generator 72 and the second generator 74 are connected by wires. Specifically, the circuit adopts a bridge rectifier circuit, and a Schottky diode is added to the output terminal to prevent current backflow. The DC outputs after rectification of the two circuits are connected in parallel through a common DC bus. The parallel power is connected to a DC-DC step-down voltage regulator module, and then input to the energy storage module 5. The energy storage module 5 is then connected to the controller 6, the electric control valve 8, the sensing component 9 and other load components.

[0029] The DC power after the current is combined is connected to the DC-DC step-down voltage regulator module, which stabilizes the fluctuating DC voltage (usually 5-20V after rectification) down to the rated voltage of the supercapacitor 51, preventing the supercapacitor 51 from being damaged by excessive voltage, while ensuring a stable charging current.

[0030] The current, after being stepped down and regulated, is input into the supercapacitor 51 to achieve energy storage. Because the supercapacitor 51 has the characteristic of instantaneous high current charging and discharging, it can quickly absorb the "peak charge" generated by the first generator 72 and the second generator 74 (such as the short-term high current caused by the instantaneous high flow velocity of water during flushing), which solves the problem of energy collection caused by intermittent power generation of water flow and ensures efficient energy storage.

[0031] Through the above structure and process, the self-generating device 7 can make full use of the kinetic energy of water flow during water supply and flushing, and can achieve self-sufficiency in electricity without external power supply. In particular, it is well-suited to the energy storage characteristics of the supercapacitor 51, which significantly improves the energy efficiency and endurance of the device.

[0032] When an external water source replenishes water to the pressure tank 1, the water flows continuously along the water supply circuit 2. Through the design of the pipe diameter and flow rate of the water supply circuit 2, the duration of each water supply is set to 20-30 seconds, the flow rate is 0.8-1.2 m / s, the first impeller 71 is driven to rotate by the water flow, driving the first generator 72 to continuously generate power of 0.3-0.5W, and the replenished water can recover 1.67mWh-4.17mWh.

[0033] The water body is provided with kinetic energy through the continuous pressure of the pressure tank 1. The water flow velocity is 1.5m / s-2m / s and the water flow duration is short, only 2-5 seconds. The second impeller 73 drives the second generator 74 to generate 1W-2W of power in a short time. The energy recovered by a single flush is 0.56mWh to 2.78mWh.

[0034] Reference Figure 1 As shown, in a first embodiment of the pressure water tank 1: the pressure water tank 1 includes a tank body 11, and a partition 12 is provided inside the tank body 11. The outer periphery of the partition 12 is sealed against the inner wall of the tank body 11 to divide the interior of the tank body 11 into a water storage chamber and an air chamber. Preferably, the air chamber and the water storage chamber are arranged vertically at intervals. An air supply hole 13 is provided at the upper end of the tank body 11. The air supply hole 13 communicates with the air chamber and is used to supply gas into the air chamber. An elastic member 14 is provided in the air chamber. One end of the elastic member 14 is connected to the upper end face of the partition 12, and the other end of the elastic member 14 is connected to the upper inner wall of the tank body 11.

[0035] Reference Figure 2As shown, in a second embodiment of the pressure water tank 1: the pressure water tank 1 includes a first tank body 111 and a second tank body 112. The upper end of the first tank body 111 is provided with the air inlet 13. The partition 12 is disposed inside the first tank body 111 to divide the interior of the first tank body 111 into a lower water storage chamber and an upper air chamber. The first tank body 111 and the second tank body 112 are connected by a first pipe 15 and a second pipe 16, which are respectively connected to the upper and lower sides of the partition 12. The first pipe 15 is equipped with a one-way valve 17 to prevent water from the second tank 112 from entering the air chamber through the first pipe 15. The second pipe 16 is used to balance the water pressure in the water storage chamber and the second tank 112. The flushing water path 3 includes a first flushing water path and a second flushing water path. One end of the first flushing water path is connected to the water storage chamber, and one end of the second flushing water path is connected to the second tank 112. The other ends of the first flushing water path and the second flushing water path are connected and then connected to the electric control valve 8. The water supply path 2 is connected to the second pipe 16.

[0036] The first chamber 111 and the second chamber 112 achieve real-time water pressure balance through the second pipe 16. During flushing, the second chamber 112 directly supplies water to the flushing water path 3, while the first chamber 111 continuously replenishes high-pressure water to the second chamber 112 through the second pipe 16. At the same time, the air inlet 13 at the upper end of the first chamber 111 works in conjunction with the elastic element 14. When the flushing causes the baffle 12 to move downward, the elastic element 14 releases its elasticity to help maintain the pressure, and the air inlet 13 replenishes air simultaneously to offset the pressure loss, ensuring that the pressure is stable and without fluctuation throughout the flushing process, and ensuring that the flushing water path 3 can maintain a high flow rate to ensure the power generation efficiency of the impeller.

[0037] Compared to a single-tank structure, the double-tank structure of pressure water tank 1 has the following advantages: Figure 1 The single-tank structure in the middle relies on a single water storage chamber to store water. During flushing, the water level in the water storage chamber drops rapidly. Even with the elastic component 14 and air replenishment assistance, the pressure will still fluctuate significantly as the water level drops, which can easily lead to insufficient flushing force at the end of the flush. Figure 2 In the dual-tank structure, the second tank 112 serves as a direct water supply chamber, specifically providing high-pressure water for the flushing water path 3. The first tank 111 acts as a pressure compensation, connecting the first tank 111 and the second tank 112 in real time via the second pipe 16. During flushing, water flows out from the second tank 112, and the high-pressure water in the first tank 111 is simultaneously replenished to the second tank 112 through the second pipe 16, ensuring that the water pressure in the second tank 112 remains stable within the rated range, resulting in uniform flushing force throughout the process, improving the flushing efficiency of the toilet body 4, and preventing flushing force attenuation.

[0038] As a preferred embodiment, the elastic element 14 described above can adopt a spring structure in the prior art.

[0039] Reference Figure 3 As shown, in a third embodiment of the pressure water tank 1: the pressure water tank 1 includes a tank body 11, a water supply path 2, and a flushing path 3 connected to the tank body 11. The water supply path 2 is equipped with a one-way inlet valve 21 and a Venturi valve 22 in sequence according to the water flow direction, and also includes a one-way air inlet valve 23 connected to the Venturi valve 22. During water supply, water passes through the one-way inlet valve 21 and then through the Venturi valve 22, finally entering the tank body 11. During the entire water intake process, air can be simultaneously drawn into the tank body 11 through the one-way air inlet valve 23 to replenish the air in the tank body 11. As more and more water is added to the tank body 11, the air is compressed. When the air pressure and water pressure are balanced, water intake stops. During flushing, the drain control valve 8 opens, water is discharged through the flushing path 3, the compressed air in the tank body 11 gradually returns to atmospheric pressure, and then drainage stops.

[0040] Furthermore, the toilet body 4 includes a toilet base 41, a toilet seat ring 42, and a toilet lid 43; the sensing probe 9 includes a distance sensor 91 disposed on the toilet lid 43, and a signal pairing component 92 disposed on the toilet base 41 and the toilet lid 43 respectively. When the controller 6 detects that the signal pairing component 92 is in a signal disconnected state, the controller 6 wakes up the distance sensor 91.

[0041] If a user enters or exits the bathroom, or passes by the toilet, and the distance sensor 91 continues to detect, it may accidentally trigger a false wake-up due to the distance falling into the detection range. By setting the signal pairing component 92 on the toilet seat 43 and the toilet base 41 respectively, the distance sensor 91 will be automatically woken up when the user manually opens the toilet seat 43 to use the toilet.

[0042] Reference Figure 4 As shown, preferably, the signal pairing component 92 includes a permanent magnet and a Hall sensor. The permanent magnet is disposed on the toilet base 41, and the Hall sensor is disposed on the toilet seat 43. Compared with infrared emitting tubes and infrared receiving tubes, the permanent magnet and Hall sensor as the signal pairing component 92 have the advantage of low power consumption, which significantly reduces the energy consumption burden of the energy storage module 5 and is suitable for the limited energy output of the self-generating device 7.

[0043] The toilet body 4 is equipped with an LED light. When the signal pairing component 92 is disconnected, the controller 6 controls the LED light to turn on; when the signal pairing component 92 is connected, the controller 6 controls the LED light to turn off. The LED light turning on when the signal pairing component 92 is disconnected indicates that the distance sensor 91 is in working condition; the LED light turning off when the signal pairing component 92 is connected indicates that the distance sensor 91 is not in working condition. Therefore, if the user opens the toilet lid 43 but the LED light does not turn on, there may be a circuit fault, thus providing feedback on whether the control circuit and electronic components are functioning properly.

[0044] In the above text, the elastic element 14 includes, but is not limited to, springs in the prior art, and the electric control valve 8 includes, but is not limited to, solenoid valves, electric ball valves, electric butterfly valves, etc. in the prior art.
