Description
Technical Field
[0001] This invention relates to the field of piped drinking water equipment technology, and in particular to an intelligent control device for circulating and returning piped drinking water. Background Technology
[0002] Piped drinking water, short for "high-quality direct drinking water," refers to tap water that has undergone advanced treatment to remove organic matter, bacteria, viruses, and other harmful substances. This treated water is then supplied to users through high-quality water pipes for daily use, such as drinking, cooking, and washing fruits and vegetables. Because the volume of water treated in piped drinking water systems is relatively small, and the water quality requirements are high, membrane filtration technology is generally used to meet these specific needs. Currently, the most commonly used membrane elements in these processes include microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes. Each membrane purification technology has a clearly defined scope of application; therefore, in the design of advanced purification processes, it is essential to select the appropriate technology based on the specific characteristics of the local tap water source and the user's requirements for drinking water.
[0003] Piped drinking water systems are equipped with a recirculation system to return drinking water that has been stagnant in the pipes for an extended period to the water supply system. This prevents the accumulated drinking water from failing to meet drinking water standards due to bacterial growth. In existing technologies, traditional recirculation systems often use a water pump and sensors to periodically transfer drinking water from the water treatment equipment and faucets back into the water supply system for other uses or further treatment. However, in scenarios such as schools and communities with numerous water points, long water supply pipelines, and renovations to existing pipelines, traditional recirculation systems are difficult to install, consume a lot of energy, and require extensive circuitry, resulting in high installation costs. Therefore, we propose an intelligent control system for recirculating drinking water in piped systems to address these issues. Summary of the Invention

[0010] Preferably, the transmission gear assembly includes a support frame fixedly connected to the inner wall of the housing, a main gear rotatably connected to the support frame and meshing with a rack, a secondary gear fixedly connected to one side of the main gear, and a driven gear meshing with the secondary gear fixedly connected to the output end of the generator.
[0011] Preferably, the drive frame includes an annular rod, and symmetrically arranged drive plates are fixedly connected to the lower surface of the annular rod. The drive plates are provided with inclined grooves, and a T-shaped rod is fixedly connected to the side of the arc-shaped blocks that is far apart from each other. The T-shaped rod passes through the inclined groove.
[0012] Preferably, the lower end of the water storage tank is provided with a receiving trough, and the water inlet pipe is located close to the receiving trough.
[0013] Preferably, a distance sensor is provided on the lower inner wall of the water storage tank, and the distance sensor is electrically connected to the control module.

[0015] Preferably, the locking directions of the two one-way bearings are opposite, and the rotating rod and the lever are symmetrically arranged.
[0016] Preferably, the push block is triangular, and a pulley is rotatably connected to the end of the connecting rod near the push block.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. This invention, by setting up a drive component, when a user uses direct drinking water, the pressure inside the pipeline changes due to water hammer caused by the user opening and closing the tap supplying direct drinking water. At this time, the piston located in the connecting pipe is driven by the pressure change caused by the water hammer, which in turn, in conjunction with the connecting rod and the rotating rod, causes the lever to drive the sliding sleeve to rotate. Thus, when the user uses direct drinking water, the pressure plate in the water storage tank discharges the water in the water storage tank, and the stagnant water in the water storage tank is transported to the water supply pipeline for other purposes or for further water treatment. On the one hand, there is no need for an additional drive device to drive the stagnant water, and on the other hand, it can reduce the impact of water hammer on the direct drinking water pipeline and improve the service life of the direct drinking water pipeline.
[0019] 2. In this invention, if drinking water is not drained from the pipes in time during nighttime or holidays and stagnant water forms in the pipes, the control module will control the electric push rod to move after a certain period of time, causing the two arc-shaped blocks to move away from each other. At this time, the pressure plate loses its supporting force, and the stagnant water in the pipes enters the water storage tank under the water pressure and drives the pressure plate to move upward, thereby replacing the drinking water in the pipes with fresher drinking water, ensuring that the drinking water flowing from the tap always meets the relevant standards for drinking water.
[0020] 3. This invention, by setting up a power supply component, adopts a shell in conjunction with a platform and a generator. When a user takes water, the user uses their own weight to move the platform downwards, which, in conjunction with a rack and pinion gear set, drives the generator to run, thereby converting the user's own gravitational potential energy into electrical energy to provide a stable power supply for the control module. There is no need to lay power lines simultaneously when deploying the drinking water equipment, which not only reduces the equipment deployment cost, but is also more energy-efficient and environmentally friendly. At the same time, the drinking water needs to be taken for a certain period of time, which can ensure that the power generation of the generator meets the usage requirements of the control module. It is especially suitable for scenarios with high traffic and high usage, such as communities and schools.
[0021] 4. This invention, by setting up a variable speed gear set, can make the generator rotate at high speed by the transmission of multiple gears after the user stands on the platform, ensuring that the power generation of the generator meets the demand. On the other hand, the variable speed gear set also limits the speed of the platform when it descends and ascends, thereby improving the stability of the functional components when in use and preventing the user from falling due to instability when climbing onto or leaving the platform, or from spilling drinking water when carrying a cup to hold drinking water.
[0022] 5. This invention, by setting up a drive motor, is used to drive the sliding sleeve to rotate when the driving force generated by the water hammer phenomenon cannot completely drain the stagnant water in the water storage tank. This causes the pressure plate to move downward and drain the stagnant water in the water storage tank, ensuring that this type of water return device can effectively guide the stagnant water back into the water supply pipeline and ensure that the quality of the direct drinking water meets the drinking water standards.

Detailed Implementation
[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0032] Reference Figure 1-7 A smart control piped direct drinking water circulation and return device includes a water storage tank 1, a drive component is installed inside the water storage tank 1, and a power supply component is installed on one side of the water storage tank. The power supply component is electrically connected to the drive component, wherein:
[0033] The drive assembly includes a connecting pipe 2 fixedly connected to the water storage tank 1. The connecting pipe 2 serves as the chamber of the piston 3, with one end connected to a direct drinking water pipeline and the other end connected to the water storage tank 1. The connecting pipe 2 has an exhaust port to prevent slippage due to air pressure. A piston 3 is slidably connected inside the connecting pipe 2, and a connecting rod 4 is fixedly connected to the end of the piston 3 closest to the water storage tank 1. Rotating rods 5 are rotatably connected to both sides of the connecting rod 4, and levers 6 are rotatably connected to the ends of the two rotating rods 5 away from the connecting rod 4. A sliding sleeve 7 is rotatably connected inside the water storage tank 1, and symmetrically arranged arc-shaped blocks 8 are slidably connected inside the sliding sleeve 7. The arc-shaped blocks 8 have spiral grooves. Both levers 6 are rotatably connected to the sliding sleeve 7 via one-way bearings. In this design, When a user turns the drinking water faucet on and off, the pressure change caused by the water hammer phenomenon drives the piston 3 to move within the connecting pipe 2, which in turn drives the sliding sleeve 7 to rotate via the lever 6. The locking directions of the two one-way bearings are opposite. The rotating rod 5 and the lever 6 are symmetrically arranged. A vertically arranged screw 9 is also provided inside the sliding sleeve 7. The lower end of the screw 9 is fixedly connected to a pressure plate 10, and the pressure plate 10 is interference-fitted with the inner wall of the water storage tank 1. The lower end of the water storage tank 1 is connected to an inlet pipe 11 and an outlet pipe 12 via a one-way valve. The inlet pipe 11 is connected to the drinking water pipeline near the faucet, while the outlet pipe 12 is connected to the inlet pipe 11. The flow direction of the one-way valve is from the drinking water pipeline to the inlet pipe 11 and from the water storage tank 1 to the outlet pipe 12.
[0034] The power supply assembly includes a housing 13, within which a platform 14 is slidably connected. A vertically arranged spring rod 15 is fixedly connected within the housing 13, with its upper end abutting against the lower surface of the platform 14. A generator 16 is fixedly connected within the housing 13, and a transmission gear set 17 is provided at the output end of the generator 16. A rack is fixedly connected to the lower end of the platform 14, meshing with the transmission gear set 17. The generator 16 is electrically connected to a battery 18, which is electrically connected to a control module. An electric push rod 19 is fixedly connected within the water storage tank 1, with its output end fixedly connected to a drive frame. An arc-shaped block 8 is slidably connected to the drive frame. A push block 20 is also fixedly connected to the drive frame. The push block 20 is connected to the drive frame... The rods 4 are set together, the push block 20 is triangular, and the end of the connecting rod 4 near the push block 20 is rotatably connected to a pulley. In this design, the spring rod 15 is existing technology and is used to drive the platform 14 to reset. The platform 14 is located near the drinking water supply point. When users take drinking water, they can stand on the platform 14, thereby realizing the conversion of the gravitational potential energy of the user after climbing onto the platform 14 into kinetic energy to drive the generator 16 to run, and then into electrical energy to drive the control module. The design of the gear set 17 can limit the downward movement speed of the platform 14, making it more stable when the user stands on the platform 14. The spring rod 15 is used to reset the position of the platform 14 on the one hand, and on the other hand, it is used to convert the elastic potential energy of the spring rod 15 into electrical energy when resetting the platform 14.
[0035] Furthermore, a partition 21 is fixedly connected inside the water storage tank 1, and the sliding sleeve 7 is installed through the partition 21. A drive motor 22 is fixedly connected inside the water storage tank 1, and the drive motor 22 is located above the partition 21. The output end of the drive motor 22 is fixedly connected to the sliding sleeve 7. The control module is electrically connected to the drive motor 22. The drive component is easily affected by the frequency of use of the drinking water and the water pressure, and may fail to drive the pressure plate 10 to a position close to the bottom of the water storage tank 1. Therefore, the drive motor 22 is set as a backup power to ensure that the return water device can completely transport the stagnant water in the drinking water pipe back to the water supply pipe.
[0036] Furthermore, the gear set 17 includes a support frame 171 fixedly connected to the inner wall of the housing 13. A main gear 172 meshing with a rack is rotatably connected to the support frame 171. A secondary gear 173 is fixedly connected to one side of the main gear 172. A driven gear 174 meshing with the secondary gear 173 is fixedly connected to the output end of the generator 16. The number of teeth of the main gear 172 is less than the number of teeth of the secondary gear 173, and the number of teeth of the driven gear 174 is also less than the number of teeth of the secondary gear 173. In practical applications, the gear ratio can be further adjusted by setting gear components with the same structure as the main gear 172 and the secondary gear 173 according to actual needs. Its purpose is to use the user's gravitational potential energy to convert into kinetic energy to drive the generator 16 to rotate at high speed, while limiting the speed of the platform 14 when it moves downward and rebounds upward, so as to prevent users standing on the platform 14 from losing their balance and falling when climbing onto or leaving the platform 14, or from spilling drinking water when carrying a cup.
[0037] Furthermore, the drive frame includes an annular rod 23, and a symmetrically arranged drive plate 24 is fixedly connected to the lower surface of the annular rod 23. The drive plate 24 has a slanted groove 25. A T-shaped rod 26 is fixedly connected to the side of the arc-shaped blocks 8 that is far apart from each other. The T-shaped rod 26 passes through the slanted groove 25. The drive plate 24 is composed of an arc-shaped rod and a plate body. On the one hand, it will not interfere with the rotation of the arc-shaped blocks 8 with the sliding sleeve 7. On the other hand, it can ensure that when the electric push rod 19 is running, it can drive the arc-shaped blocks 8 to move in the direction of approaching or moving away from each other, so as to control the position of the pressure plate 10.
[0038] Furthermore, the lower end of the water storage tank 1 is provided with a receiving groove 27, and the water inlet pipe 11 is located close to the receiving groove 27. In this design, the water pressure in the drinking water pipeline is needed to push the pressure plate 10 back to its initial position, and the stagnant water in the drinking water pipeline is injected into the water storage tank 1 at this time. Therefore, when the pressure plate 10 drains the water in the water storage tank 1, it is necessary not to directly block the connection point between the water inlet pipe 11 and the water storage tank 1.
[0039] Furthermore, a distance sensor 28 is provided on the lower inner wall of the water storage tank 1, and the distance sensor 28 is electrically connected to the control module. The distance sensor 28 is used to detect the distance between the pressure plate 10 and the bottom of the water storage tank 1, thereby determining whether the pressure plate 10 has completely discharged the stagnant water in the water storage tank 1, ensuring that when the water inlet pipe 11 delivers stagnant water into the water storage tank 1, the stagnant water in the direct drinking water pipeline can be completely discharged into the water storage tank 1.
[0040] The control module includes a water flow sensor electrically connected to the battery 18, a timer electrically connected to the water flow sensor, a signal processor electrically connected to the timer, a wireless communication module electrically connected to the signal processor, a relay electrically connected to the signal processor, and an electric push rod 19 electrically connected to the relay.
[0041] In this invention, during daily use of direct drinking water, users stand on platform 14 to collect water. When a user steps onto platform 14, the platform moves downward, converting the user's gravitational potential energy into the platform's kinetic energy. Platform 14, in conjunction with rack and pinion and gear set 17, drives generator 16 to rotate, thereby converting gravitational potential energy into electrical energy to power the control module and storing it in battery 18 for later use. After the user collects water and leaves platform 14, the elastic potential energy of spring rod 15 is converted into kinetic energy to return platform 14 to its initial position. This also drives generator 16 and limits the platform's speed, improving the stability and safety of the power supply components. In communities, schools, and other scenarios with high traffic and frequent water collection, the power generated by the power supply components can meet the power requirements of the control module and is sufficient to drive motor 22, eliminating the need to simultaneously lay power supply pipelines when modifying the water supply system.
[0042] On the other hand, when users take drinking water, the frequent opening and closing of the faucet causes water hammer, which changes the pressure in the water supply pipeline. This causes piston 3 to reciprocate within connecting pipe 2, which, in conjunction with rotating rod 5, lever 6, and two one-way bearings, drives sliding sleeve 7 to rotate. The rotation of sliding sleeve 7 drives arc-shaped block 8 to rotate, which in turn causes screw 9 to move pressure plate 10 downwards, discharging stagnant water from storage tank 1. After the drinking water pipeline has not been used for a long time, pressure plate 10 is at the bottom of storage tank 1. When the control module is running, it controls electric push rod 19, causing it to move in conjunction with drive frame to move two arc-shaped blocks 8 away from each other. The drinking water purification equipment then inputs fresh drinking water into the drinking water pipeline, while stagnant water in the pipeline flows into storage tank 1, driving pressure plate 10 upwards, allowing stagnant water to flow into storage tank 1. Push block 20 drives connecting rod 4 to move further away from the pressure plate. Moving away from the sliding sleeve 7, the piston 3 pushes the water out of the connecting pipe 2, preventing stale water from remaining in the connecting pipe 2 and ensuring that fresh drinking water is available the next time the tap on the drinking water pipeline is turned on. It should be noted that, normally, the water in the drinking water pipeline needs to pass through the drinking water purification equipment first. While the drinking water purification equipment is purifying the water, it also causes a drop in water pressure. The end of the outlet pipe 12 away from the water storage tank 1 is connected to the water supply pipeline. At this time, the water pressure in the drinking water pipeline is lower than that in the water supply pipeline. Therefore, when the drive component is not running, the water in the drinking water pipeline cannot flow directly into the water supply pipeline through the water storage tank 1, resulting in waste of drinking water. This type of water return device is mainly used in high-frequency and high-traffic communities and schools. When the usage frequency is high, the drive component can fully meet the needs of circulating water return, reduce the impact of water hammer on the drinking water pipeline, and improve the service life of the drinking water pipeline.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
