[0017] 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.
[0018] Reference Figures 1 to 3 As shown, a self-generating smart toilet based on a gravity water tank includes: Gravity water tank 1 is used to store the water required for flushing and to provide flushing force using the gravity of the water. Water supply line 2, one end of which is connected to an external water source and the other end is connected to the gravity water tank 1, for replenishing water to the gravity water tank 1; The flushing water passage 3 has one end connected to the outlet of the gravity water tank 1, and the other end is set in the flushing area of the toilet body 4, used to transport the water in the gravity water tank 1 to the toilet body 4 to achieve 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, its signal receiving terminal electrically connected to the sensing probe 9 to receive flushing signals, and 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.
[0019] 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 gravity 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.
[0020] 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.
[0021] The height difference between the gravity water tank 1 and the toilet body 4 is 1 to 1.5 meters to ensure the water flow speed is sufficient to drive the impeller for efficient power generation. If the height difference is less than 1 meter, the water flow speed converted from gravitational potential energy is too slow and the toilet cannot be flushed cleanly. If the height difference is greater than 1.5 meters, the impeller speed is positively correlated with the water flow speed, which increases the impact stress on the blades and can easily lead to blade damage.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] As a second embodiment of the self-generating device 7, refer to Figure 2 As 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.
[0026] As a third embodiment of the self-generating device 7, referring 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] When an external water source replenishes water to the gravity water tank 1, the water flows continuously along the water supply path 2. Through the design of the pipe diameter and flow rate of the water supply path 2, the duration of each water supply is set to 20-30 seconds, and the flow rate is 0.8-1.2 m / s. The first impeller 71 is driven to rotate by the water flow, which drives the first generator 72 to continuously generate power of 0.3-0.5W. The replenished water can recover 1.67mWh-4.17mWh.
[0032] The gravitational potential energy of the water is converted into kinetic energy. The flow velocity is 1.5m / s-2m / s, but 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. A single flush can recover 0.56mWh to 2.78mWh of energy.
[0033] The flushing water path 3 includes a flow stabilizing section and a flushing nozzle. The second impeller 73 is located in the flow stabilizing section, which is a straight pipe section between the outlet of the electrically controlled valve 8 and the flushing nozzle. The distance between the second impeller 73 and the outlet of the electrically controlled valve 8 is 3 to 5 times the diameter of the outlet pipe of the electrically controlled valve 8.
[0034] The aforementioned placement of the second impeller 73 maximizes the capture of stable water kinetic energy, improving power generation efficiency and stability. Specifically, this location is within the stable flow zone after the electronically controlled valve 8 is fully open, at a distance of 3-5 times the pipe diameter from the valve. Here, the water flow has transitioned from valve throttling disturbance to uniform flow, resulting in maximum flow rate and minimal fluctuations. The second impeller 73 operates at a stable speed driven by the water flow at this location, avoiding sudden changes in speed caused by turbulence near the valve. This keeps the output voltage and current fluctuations of the second generator 74 within ±10%, improving energy conversion efficiency and stably capturing the kinetic energy converted from the gravitational potential energy of the water. Positioning the second impeller 73 at this location minimizes its energy consumption on the water flow, ensuring flow stability and preserving the flushing pattern and cleaning effect. The second impeller 73 is located at the above position, which has not yet entered the flushing nozzle. The water flow velocity is only 60%-70% of that at the flushing nozzle. On the one hand, the moderate flow velocity avoids overloading the impeller. On the other hand, the high water pressure provides sufficient driving force for the impeller, ensuring that the generator can reach the rated power.
[0035] Furthermore, the toilet body 4 includes a toilet base 41, a toilet seat 42, and a toilet lid 43; the sensing probe 9 includes a first transceiver signal group 91 and a second transceiver signal group 92, wherein the first transceiver signal group 91 is respectively disposed on the toilet base 41 and the toilet seat 42, and the second transceiver signal group 92 is respectively disposed on the toilet seat 42 and the toilet lid 43; When both the first transceiver signal group 91 and the second transceiver signal group 92 are in the signal mutual recognition state, the toilet seat 42 and the toilet lid 43 are both in the closed state; when the first transceiver signal group 91 is in the signal disconnection state, the toilet seat 42 is in the open state; when the second transceiver signal group 92 is in the signal disconnection state, the toilet lid 43 is in the open state. When the first transceiver signal group 91 is in the disconnected state, the controller 6 records the state until the first transceiver signal group 91 and the second transceiver signal group 92 both resume mutual recognition. Then, the controller 6 controls the electronically controlled valve 8 to open the flushing water path 3 with the first opening amplitude, and cuts off after flushing is completed. When the second transceiver signal group 92 is in the disconnected state, the controller 6 records the state until the first transceiver signal group 91 and the second transceiver signal group 92 both resume mutual recognition. Then, the controller 6 controls the electronically controlled valve 8 to open the flushing water path 3 with a first opening range or a second opening range, and cuts off the flow after flushing is completed.
[0036] During use, the user manually opens the toilet lid 43 or the toilet seat 42. When the user manually opens the toilet seat 42, the first transceiver signal group 91 is disconnected; when the user manually opens the toilet lid 43, the second transceiver signal group 92 is disconnected. The opening of the toilet lid 43 or the toilet seat 42 indicates that the user is using the toilet. When the user manually closes the toilet lid 43 and the toilet seat 42, both the first transceiver signal group 91 and the second transceiver signal group 92 return to mutual recognition, indicating that the user has finished using the toilet. Then, the electronically controlled valve 8 automatically opens to complete the flushing and then shuts off.
[0037] Preferably, both the first transceiver signal group 91 and the second transceiver signal group 92 are Hall effect sensor modules, each comprising a permanent magnet and a Hall sensor. In the first transceiver signal group 91, the permanent magnet is disposed on the toilet seat 42, and the Hall sensor is disposed on the top surface of the toilet base 41; in the second transceiver signal group 92, the permanent magnet is disposed on the toilet seat 42, and the Hall sensor is disposed on the bottom surface of the toilet lid 43. The first transceiver signal group 91 and the second transceiver signal group 92 can share the same permanent magnet. Compared to using infrared emitters and receivers as transceiver signal groups, the permanent magnet and Hall sensor in the first transceiver signal group 91 and the second transceiver signal group 92 have the advantage of low power consumption, significantly reducing the energy consumption burden of the energy storage module 5 and adapting to the limited energy output of the self-generating device 7.
[0038] Furthermore, the controller 6 is also used to record the disconnection duration of the second transceiver signal group 92. When the disconnection duration is less than a set threshold, the controller 6 controls the electronically controlled valve 8 to open the flushing water path 3 with a first opening amplitude, and then cuts off the flow after flushing is completed. When the disconnection duration exceeds the set threshold, the controller 6 controls the electronically controlled valve 8 to open the flushing water path 3 with a second opening amplitude, and then cuts off the flow after flushing is completed. The first opening amplitude is less than the second opening amplitude.
[0039] Specifically, the threshold value is preferably 2 minutes. When the controller 6 records that the disconnection time of the second transceiver signal group 92 is less than 2 minutes, it determines that the user is in a sitting or standing urination state. When the controller 6 records that the disconnection time of the second transceiver signal group 92 is greater than 2 minutes, it determines that the user is in a sitting or standing defecation state.
[0040] By using the above steps to distinguish between urination and defecation, when the user finishes urinating, the electric control valve 8 opens the flushing water path 3 with a first opening degree; when the user finishes defecation, the electric control valve 8 opens the flushing water path 3 with a second opening degree. The first opening degree is smaller than the second opening degree. The water requirements for flushing vary significantly depending on the usage scenario: only a small amount of water is needed for urination, while a larger amount of water is needed for defecation to completely drain the waste. The above control steps help to save water.
[0041] The toilet body 4 is equipped with an LED light. When both the first transceiver signal group 91 and the second transceiver signal group 92 are in a signal mutual recognition state, the LED light emits a first color light; when the first transceiver signal group 91 is in a signal disconnection state, the LED light emits a second color light; when the second transceiver signal group 92 is in a signal disconnection state, the LED light emits a third color light.
[0042] The different colors of the LED lights provide feedback, making it easy for users to distinguish the identification status of the first transceiver signal group 91 and the second transceiver signal group 92.
[0043] In the above text, the electrically controlled valve 8 includes, but is not limited to, solenoid valves, electric ball valves, electric butterfly valves, etc., which are existing technologies.
