Description

Technical Field

[0001] The present application relates to the technical field of secondary water supply, and in particular to a secondary water supply ultraviolet light disinfection system. Background Art

[0002] Secondary water supply refers to the water supply method that supplies water to users or for their own use through pipelines using storage, pressurization and other facilities when the water pressure and water volume requirements for drinking water in civil and industrial buildings exceed the capacity of urban public water supply or self-built water supply network. Secondary water supply facilities mainly include three parts: water storage equipment, pressurization equipment and pipelines. Tap water will stay in the secondary water supply storage equipment (hereinafter referred to as the water storage equipment) for a period of time. If the stay time is too long, the residual chlorine concentration at the outlet of the water storage equipment may decay to a very low level, which will not effectively kill the microorganisms in the water, causing the microbial indicators of the tap water flowing out of the water storage equipment to exceed the standard. In order to solve this problem, the existing technology generally adds ultraviolet catalytic lamps and chlorine content detectors to the water storage equipment for additional disinfection and sterilization of the water. The principle is to use the chlorine content detector to detect the residual chlorine content in the water, and then adjust the intensity of the ultraviolet catalytic lamp according to the level of the detected chlorine content decay in the water, so as to achieve additional disinfection and sterilization of the water in the water storage equipment.

[0003] However, to ensure the accuracy of chlorine detectors, they are typically installed in the middle of the water storage unit in most scenarios. However, during peak water usage, large amounts of high-chlorine water are rapidly added to the water storage unit, flowing out of the outlet before fully mixing with the pre-stored water. During this process, the chlorine detector comes into contact with either only the newly added water or only the pre-stored water. This results in the chlorine content measured by the chlorine detector being either higher or lower than the actual chlorine content of the water flowing out of the outlet. Consequently, the UV catalytic lamps either over-irradiate the water, wasting energy, or under-irradiate the water, resulting in a less-than-optimal sterilization effect. Furthermore, prolonged immersion of the water storage unit and UV lamps in water can cause a biofilm to form on their surfaces, affecting water quality and reducing the UV lamp's intensity, thereby diminishing its sterilization and disinfection effectiveness. Summary of the Invention

[0004] In order to reduce energy consumption during ultraviolet lamp disinfection and improve disinfection efficiency and water quality, the present application provides a secondary water supply ultraviolet light disinfection system.

[0005] The secondary water supply ultraviolet disinfection system provided in this application adopts the following technical solutions: A secondary water supply ultraviolet disinfection system, comprising: A water storage tank, wherein the top and bottom of the water storage tank are respectively provided with a water inlet connected to an external water supply pipeline and a water outlet connected to an external water pipe; A disinfection assembly comprising a chlorine content detector and an ultraviolet lamp; the chlorine content detector is used to detect the residual chlorine content of the water inside the water tank; the ultraviolet lamp is arranged along the height direction of the water tank and is used to irradiate the water inside the water tank; the chlorine content detector is electrically connected to the ultraviolet lamp, and the chlorine content detector can adjust the illumination intensity of the ultraviolet lamp according to the attenuation of the chlorine content in the water detected; A steady flow and decontamination component, comprising an annular plate, a magnetic plate, and a magnetic block; the annular plate is slidably arranged in the water tank along the height direction of the water tank, and the inner and outer ring walls of the annular plate are respectively in sliding contact with the outer wall of the ultraviolet lamp and the inner wall of the water tank, and the annular plate is provided with flow holes passing through its upper and lower surfaces; the magnetic plate is slidably arranged on the water tank along the height direction of the water tank, and the magnetic plate can close the water inlet when it slides upward; the magnetic block is arranged on the annular plate, and the magnetic block and the magnetic plate can be magnetically attracted to each other, so as to drive the magnetic plate to slide together when the annular plate slides; a driving assembly, wherein the driving assembly can use the impact force of water flow when water is discharged from the water outlet to drive the annular plate to rise, and the annular plate can fall freely when the water outlet stops discharging water; The water pump is arranged between the external water supply pipe and the water outlet, and is used to extract water from the water storage tank and output it to the external water supply pipe.

[0006] By adopting the above technical solution, energy consumption during UV lamp disinfection can be reduced, improving disinfection efficiency and water quality. Specifically, when water is used, the drive assembly uses the impact force of the water flowing out of the water outlet to drive the annular plate upward. As the annular plate rises, the magnetic block drives the magnetic plate upward synchronously until the magnetic block closes the water inlet, preventing water from the external water supply pipe from entering the water tank and keeping the water in the tank relatively static. At this point, a chlorine content detector can accurately detect the chlorine content of the water in the water tank and adjust the UV lamp intensity based on the test results to achieve precise disinfection and sterilization of the water in the water tank. When water is no longer used, the annular plate falls back to its initial position under the action of its own gravity, and the magnetic plate then opens the water inlet, allowing the external water supply pipe to begin replenishing water to the water tank. As the annular plate rises and falls, its inner and outer ring walls slide against the outer walls of the UV lamp and the inner wall of the water tank, effectively scraping off biofilm adhering to the inner walls of the water tank and UV lamp, ensuring clean water quality and the proper function of the UV lamp. At the same time, as the annular plate descends, it pushes water flowing from the water inlet downward, accelerating the mixing of new and old water within the tank. This improves the accuracy of chlorine content detection in the water and avoids detection errors caused by water stratification. Furthermore, through the coordinated control of the chlorine content detector and the UV lamp, the UV lamp's illumination can be flexibly adjusted based on the actual attenuation of chlorine content in the water, ensuring disinfection effectiveness while avoiding energy waste.

[0007] Optionally, the drive assembly includes a rotating shaft, a paddle, a screw, a first bevel gear and a second bevel gear; the rotating shaft is rotatably arranged at the water outlet; the paddle is arranged on the rotating shaft and can use the impact of water flow when water flows out of the water outlet to drive the rotating shaft to rotate; the screw is rotatably connected to the inner wall of the water tank and is threadedly connected to the annular plate, and the rotation axis of the screw is parallel to the sliding direction of the annular plate; the first bevel gear is arranged on the rotating shaft, and the second bevel gear is arranged on the screw and meshes with the first bevel gear; after the rotating shaft rotates, it can drive the screw to rotate through the first bevel gear and the second bevel gear.

[0008] By employing this technical solution, the impact force of water flowing out of the outlet drives the paddles, which in turn rotates the shaft. The first bevel gear on the shaft meshes with the second bevel gear, transmitting the rotational motion to the screw. As the screw rotates, its threaded connection with the annular plate drives the plate upward, along the height of the water tank. This design efficiently converts the impact force of the water flow, requiring no additional energy to raise and lower the annular plate, thereby driving the magnetic plate to close the water inlet, ensuring a stable water flow and achieving the desired decontamination function.

[0009] Optionally, the drive assembly further includes a ratchet and a magnetic coupling; the first bevel gear is connected to the rotating shaft through the ratchet and is coaxial with the rotating shaft, and the second bevel gear is connected to the screw rod through the magnetic coupling and is coaxial with the screw rod.

[0010] By adopting this technical solution, a ratchet wheel achieves one-way transmission of the rotating shaft, effectively preventing the annular plate from driving the rotating shaft in the opposite direction during its descent, thereby preventing the paddles from extracting water from the external water pipe and creating negative pressure that could impact the normal operation of the system. Furthermore, the magnetic coupling design disconnects the transmission between the second bevel gear and the screw if the water outlet continues to flow after the annular plate has risen to its highest position in the water tank. This prevents the paddles from obstructing normal water flow due to the shaft's cessation of rotation, thus ensuring the stability and reliability of the system.

[0011] Optionally, a chip groove is provided on the inner wall of the water tank, and the chip groove extends along the height direction of the water tank; the magnetic plate is slidably arranged in the chip groove, and the magnetic plate can generate magnetic force to adsorb metal impurities in the water; the magnetic block and the magnetic plate slide and abut against each other when the magnetic block and the magnetic plate are magnetically adsorbed; a chip box is detachably connected to the water tank, and the opening of the chip box is connected to one end of the chip groove located at the bottom of the water tank.

[0012] By adopting this technical solution, the magnetic plate generates a magnetic force that effectively absorbs free metal impurities in the water and guides them into the chip trough for collection. When the annular plate freely falls due to the cessation of water discharge from the outlet, the magnetic attraction between the magnetic block and the magnetic plate causes the magnetic block to slide against the plate, thereby scraping off the metal impurities adsorbed on the magnetic plate and pushing them into the chip box for storage. This process automatically cleans the metal impurities in the water tank, preventing their long-term accumulation and thus preventing water pollution. Furthermore, the chip box is mounted on the water tank via a detachable connection, facilitating regular disassembly and cleaning, further enhancing the system's ease of maintenance.

[0013] Optionally, it also includes a transmission assembly, which includes a driving wheel, a driven wheel and a transmission belt; the ultraviolet lamp is rotatably connected to the water tank, and the rotation axis of the ultraviolet lamp is parallel to the sliding direction of the annular plate; the driving wheel is arranged on the screw rod and rotates coaxially with the screw rod, the driven wheel is arranged on the ultraviolet lamp and rotates coaxially with the ultraviolet lamp, and the transmission belt is sleeved on the driving wheel and the driven wheel.

[0014] By adopting the above-mentioned technical solution, the arrangement of the transmission assembly can utilize the rotation of the screw to drive the rotation of the ultraviolet lamp. Specifically, when the screw rotates, the driving wheel rotates accordingly and drives the driven wheel to rotate through the transmission belt, thereby causing the ultraviolet lamp to rotate around its own axis. This design enables the ultraviolet lamp to achieve all-round irradiation when disinfecting and sterilizing the water in the water tank, effectively avoiding blind spots in illumination and significantly improving the disinfection effect. At the same time, the rotating design of the ultraviolet lamp can also make up for the blind spots in illumination that may occur when some lamp beads or lamp tubes are damaged. Even if individual lamp beads or lamp tubes fail, the ultraviolet lamp as a whole is in a rotating state, which can still ensure that the water in the water tank is evenly and effectively disinfected. In addition, the rotation of the ultraviolet lamp helps to reduce the formation of biofilm on its surface, maintain the irradiation intensity of the ultraviolet lamp, and further improve the sterilization efficiency.

[0015] Optionally, it also includes a water replenishment component, which includes a sliding rod, a float, a contact switch and a normally closed control valve; the sliding rod passes through the flow hole and is arranged in the water tank along the height direction of the water tank; the float is slidably set on the sliding rod and can slide up and down with the water level in the water tank; the contact switch is arranged in the water tank; a water replenishment port connected to an external water supply pipe is also opened at the bottom of the water tank, and the normally closed control valve is arranged at the water replenishment port for controlling the on and off of the water replenishment port; the contact switch is electrically connected to the normally closed control valve, and the float can trigger the contact switch to open the normally closed control valve when it is at the lowest water level.

[0016] By adopting this technical solution, when the water level in the water tank drops to the minimum level due to continuous water use, the float follows the water level drop and triggers the contact switch, which in turn controls the normally closed control valve to open, allowing water from the external water supply pipe to flow into the water tank through the water replenishment port. This automatic water replenishment function ensures that the water level in the water tank is maintained within a reasonable range, preventing water supply interruptions or equipment idling damage caused by low water levels. Furthermore, during this process, water with a qualified chlorine content from the external water supply pipe flows directly into the water tank and participates in the water supply, eliminating the need for ultraviolet light disinfection, effectively reducing unnecessary energy consumption.

[0017] Optionally, the chlorine content detector is mounted on a float, and when the water tank reaches a maximum water level, the buoyancy generated by the float can enable the chlorine content detector to be located in the middle of the water tank.

[0018] By employing this technical solution, the position of the chlorine detector automatically adjusts as the water level fluctuates. When the water tank reaches its maximum level, the buoyancy generated by the float keeps the chlorine detector positioned in the center of the tank, ensuring it remains in the optimal detection area. This design mitigates the problem of measurement deviation caused by insufficient mixing of newly added water with pre-stored water during peak water usage, improving the accuracy of chlorine detection in water, ensuring effective disinfection, and minimizing energy waste.

[0019] Optionally, a constant pressure hole connected to the outside world is opened on the top of the water tank; a blocking block is slidably provided on the slide rod, and the blocking block floats on the water surface; when the water tank reaches the highest water level, the blocking block can block the constant pressure hole.

[0020] By adopting the above technical solution, when the water level in the water tank drops after water use, the blocking block moves downward and opens the constant pressure hole, so that the air pressure inside the water tank is balanced with the external air pressure, avoiding unstable water flow or damage to the equipment due to air pressure difference. When the water level in the water tank rises to the highest level, the blocking block will automatically float to the position of the constant pressure hole as the water surface rises to block the constant pressure hole, preventing the water in the water tank from overflowing from the constant pressure hole due to excessive water pressure, thereby ensuring the sealing and stability of the system. In addition, the design of the blocking block automatically blocking or opening the constant pressure hole as the water level changes can achieve automatic control without relying on an additional power source. This not only simplifies the system structure, but also significantly improves the reliability of the system while achieving energy-saving effects.

[0021] Optionally, a magnetic shielding cover is provided on the outer side of the magnetic block.

[0022] By employing this technical solution, the magnetic shield placed outside the magnetic block precisely controls the magnetic force's range, ensuring that it only magnetically attracts the magnetic plate without causing unnecessary interference to other non-target components within the water tank. Furthermore, the magnetic shield reduces the amount of free metal impurities in the water that are attracted by the magnetic block.

[0023] Optionally, a water purification filter element is provided in the water outlet.

[0024] By adopting the above technical solution, the setting of the water purification filter can effectively filter out residual impurities and microorganisms in the water, further improve the water quality, and ensure the safety of users' water use.

[0025] In summary, this application has the following beneficial technical effects: 1. It can reduce energy consumption during UV lamp disinfection, improving disinfection efficiency and water quality. Specifically, when water is used, the drive assembly uses the impact force of the water flowing out of the water outlet to drive the annular plate upward. As the annular plate rises, the magnetic block drives the magnetic plate upward synchronously until the magnetic plate closes the water inlet, preventing water from the external water supply pipe from entering the water tank and keeping the water in the tank relatively static. During this time, a chlorine content detector can accurately detect the chlorine content of the water in the water tank and adjust the UV lamp intensity based on the test results to achieve precise disinfection and sterilization of the water in the water tank. When water is no longer used, the annular plate falls back to its initial position under the action of its own gravity, and the magnetic plate opens the water inlet, allowing the external water supply pipe to begin replenishing water to the water tank. As the annular plate rises and falls, its inner and outer walls slide against the outer walls of the UV lamp and the inner walls of the water tank, effectively scraping off biofilm adhering to the inner walls of the water tank and UV lamp, ensuring clean water quality and the proper function of the UV lamp. At the same time, as the annular plate descends, it also presses the water flowing in from the water inlet downward, accelerating the mixing of new and old water in the water tank, improving the accuracy of chlorine content detection in the water, and avoiding detection errors caused by water stratification. In addition, through the linkage control of the chlorine content detector and the ultraviolet lamp, the illumination of the ultraviolet lamp can be flexibly adjusted according to the actual attenuation of the chlorine content in the water, ensuring the disinfection effect while avoiding energy waste. 2. A ratchet ensures one-way transmission of the rotating shaft, effectively preventing the annular plate from driving the rotating shaft in the opposite direction during descent, thereby preventing the paddles from extracting water from the external water pipe and creating negative pressure that could impact the normal operation of the system. Furthermore, the magnetic coupling design disconnects the transmission between the second bevel gear and the screw if the water outlet continues to flow even after the annular plate has risen to its highest position in the water tank. This prevents the paddles from obstructing normal water flow due to the shaft stopping, thus ensuring system stability and reliability. 3. The setting of the transmission assembly can utilize the rotation of the screw to drive the ultraviolet lamp to rotate. Specifically, when the screw rotates, the driving wheel rotates accordingly and drives the driven wheel to rotate through the transmission belt, thereby causing the ultraviolet lamp to rotate around its own axis. This design enables the ultraviolet lamp to achieve all-round irradiation when disinfecting and sterilizing the water in the water tank, effectively avoiding blind spots in illumination and significantly improving the disinfection effect. At the same time, the rotating design of the ultraviolet lamp can also make up for the blind spots in illumination that may occur when some lamp beads or lamp tubes are damaged. Even if individual lamp beads or lamp tubes fail, the ultraviolet lamp as a whole is in a rotating state, which can still ensure that the water in the water tank is evenly and effectively disinfected. In addition, the rotation of the ultraviolet lamp helps to reduce the formation of biofilm on its surface, maintain the irradiation intensity of the ultraviolet lamp, and further improve the sterilization efficiency.

[0031] The following combination Figures 1-4 This application is described in further detail.

[0032] The embodiments of the present application disclose a secondary water supply ultraviolet light disinfection system.

[0033] Reference Figure 1 and Figure 2 In this embodiment, the secondary water supply ultraviolet disinfection system includes a water tank 1, a disinfection component 2, a flow stabilization and decontamination component 3, a drive component 4, a water pump 5, a transmission component 7 and a water replenishment component 8. Specifically, the water tank 1 is a vertically placed cylindrical water tank, which can be made of stainless steel. The inner wall of the water tank 1 is smooth and has an anti-corrosion coating to reduce the formation of biofilm after long-term immersion. The top and bottom of the water tank 1 are respectively provided with a water inlet 11 connected to the external water supply pipe 100 and a water outlet 12 connected to the external water pipe 200. A water purification filter element 9 is provided in the water outlet 12, which is used to further filter particulate matter and suspended matter in the water to improve the water quality. The water purification filter element 9 can adopt a multi-layer filtration structure, including a coarse filter screen, an activated carbon layer and a precision filter membrane, which can effectively intercept impurities of different particle sizes to ensure the purity of the water discharged from the water outlet 12.

[0034] The disinfection component 2 includes a chlorine content detector 21 and an ultraviolet lamp 22. The chlorine content detector 21 is arranged inside the water tank 1 and is used to detect the residual chlorine content of the water inside the water tank 1. The ultraviolet lamp 22 is cylindrical in appearance and is mainly composed of multiple ultraviolet lamp tubes and a lampshade. The material of the lampshade can be selected from corrosion-resistant quartz glass or other transparent corrosion-resistant materials to ensure durability under long-term immersion. The ultraviolet lamp 22 is rotated along the height direction of the water tank 1 and is arranged inside the water tank 1 to irradiate the water for disinfection and sterilization. The rotation axis of the ultraviolet lamp 22 is parallel to the central axis of the water tank 1. The chlorine content detector 21 is electrically connected to the ultraviolet lamp 22. The chlorine content detector 21 can adjust the illumination intensity of the ultraviolet lamp 22 accordingly according to the level of chlorine content attenuation detected in the water.

[0035] Reference Figure 1 and Figure 3 In this embodiment, the steady flow and decontamination component 3 includes an annular plate 31, a magnetic plate 32 and a magnetic block 33. The annular plate 31 is made of stainless steel, and its inner ring diameter matches the outer diameter of the ultraviolet lamp 22, and the outer ring diameter matches the inner diameter of the water tank 1. The annular plate 31 is slidably arranged in the water tank 1 along the height direction of the water tank 1, and the inner and outer ring walls of the annular plate 31 are slidably abutted against the outer wall of the ultraviolet lamp 22 and the inner wall of the water tank 1 respectively. The annular plate 31 is provided with a plurality of flow holes 311 passing through the upper and lower surfaces thereof, and the water on the top side of the annular plate 31 and the water on the bottom side of the annular plate 31 can be mixed through the flow holes 311. The magnetic plate 32 is specifically a long strip plate with a width greater than the diameter of the water inlet 11, and its material is a high magnetic permeability neodymium iron boron magnetic material or other strong magnetic material. The magnetic block 33 is fixed to the side of the annular plate 31 , and the magnetic block 33 and the magnetic plate 32 can be magnetically attracted to each other, so that when the annular plate 31 slides along the height direction of the water tank 1 , the magnetic plate 32 is driven to slide together.

[0036] Reference Figure 1 and Figure 4In this embodiment, the drive assembly 4 includes a rotating shaft 41, a paddle 42, a screw 43, a first bevel gear 44, and a second bevel gear 45. The rotating shaft 41 is rotatably connected to the water outlet 12 of the water tank 1 through a bearing frame. The paddle 42 is fixed to the rotating shaft 41. The paddle 42 is impacted by the water flow when the water is discharged from the water outlet 12 and can drive the rotating shaft 41 to rotate. The screw 43 is also rotatably connected to the inner wall of the water tank 1 through a bearing frame and is threadedly connected to the annular plate 31. The rotation axis of the screw 43 is parallel to the sliding direction of the annular plate 31. The first bevel gear 44 is arranged on the rotating shaft 41 and is coaxial with the rotating shaft 41. When the rotating shaft 41 rotates, it can drive the first bevel gear 44 to rotate together. The second bevel gear 45 is arranged on the screw rod 43 and is coaxial with the screw rod 43. The second bevel gear 45 is engaged with the first bevel gear 44. When the second bevel gear 45 rotates, it can drive the screw rod 43 to rotate together. After the rotating shaft 41 rotates, it can drive the screw rod 43 to rotate through the first bevel gear 44 and the second bevel gear 45.

[0037] The water pump 5 is arranged between the external water pipe 200 and the water outlet 12 and is used to pump water from the water tank 1 and output it to the external water supply pipe 100 .

[0038] In this way, when water is used, water pump 5 draws water from the interior of water tank 1 through outlet 12 and outputs it to the external water supply pipe 100. The impact of the water flow on paddle 42 drives shaft 41 to rotate. The meshing of first bevel gear 44 and second bevel gear 45 drives screw 43 to rotate, causing annular plate 31 to rise along the height of water tank 1. This effectively transforms the impact force of the water flow and allows the raising and lowering of annular plate 31 to be completed without requiring additional energy. As annular plate 31 rises, magnetic block 33 drives magnetic plate 32 to move upward synchronously until magnetic plate 32 closes water inlet 11, thereby preventing water from the external water supply pipe 100 from entering water tank 1 and maintaining a relatively static state within water tank 1. At this point, chlorine content detector 21 can accurately detect the chlorine content of the water in water tank 1 and adjust the irradiation intensity of UV lamp 22 based on the detection result to achieve precise disinfection and sterilization of the water in water tank 1. When water use stops, the annular plate 31 falls back to its initial position under the action of its own gravity, and the magnetic plate 32 then opens the water inlet 11, and the external water supply pipe 100 begins to replenish water to the water tank 1. During the process of rising and falling, the annular plate 31 can scrape off the biofilm attached to the inner wall of the water tank 1 and the outer wall of the ultraviolet lamp 22, ensuring the clean water quality and the normal operation of the ultraviolet lamp 22. At the same time, when the annular plate 31 descends, it can also press the water flowing into the water inlet 11 downward, accelerating the mixing of new and old water in the water tank 1, improving the accuracy of chlorine content detection in the water, and avoiding detection errors caused by water stratification. In addition, through the linkage control of the chlorine content detector 21 and the ultraviolet lamp 22, the illumination of the ultraviolet lamp 22 can be flexibly adjusted according to the actual attenuation of the chlorine content in the water, which not only ensures the disinfection effect but also avoids energy waste.

[0039] Reference Figure 1 and Figure 4 In this embodiment, the drive assembly 4 further includes a ratchet 46 and a magnetic coupling 47. The first bevel gear 44 is connected to the rotating shaft 41 via the ratchet 46, and the second bevel gear 45 is connected to the screw 43 via the magnetic coupling 47. Thus, the ratchet 46 is used to achieve one-way transmission of the rotating shaft 41, preventing the annular plate 31 from driving the rotating shaft 41 in the opposite direction during its descent, thereby preventing the paddles 42 from extracting water from the external water pipe 200 and preventing the formation of negative pressure that would affect the normal operation of the system. At the same time, the magnetic coupling 47 can cut off the transmission between the second bevel gear 45 and the screw 43 when the water outlet 12 continues to discharge water after the annular plate 31 rises to its highest position in the water tank 1, thereby preventing the paddles 42 from obstructing the normal discharge of water from the water outlet 12 due to the cessation of rotation of the rotating shaft 41.

[0040] Reference Figure 2 and Figure 3 In this embodiment, a chip groove 13 is provided on the inner wall of the water tank 1, and the chip groove 13 extends along the height direction of the water tank 1. The width of the chip groove 13 matches the width of the magnetic plate 32, and the depth of the chip groove 13 is slightly greater than the thickness of the magnetic plate 32. The magnetic plate 32 is slidably arranged in the chip groove 13. The end of the magnetic block 33 facing away from the annular plate 31 extends into the chip groove 13, and when the magnetic block 33 and the magnetic plate 32 are magnetically attracted, the magnetic block 33 and the magnetic plate 32 slide and abut. A chip box 6 is detachably connected to the outer wall of the water tank 1, and the opening of the chip box 6 is connected to the end of the chip groove 13 located at the bottom of the water tank 1; when the annular plate 31 falls, it can drive the magnetic block 33 to scrape the metal impurities adsorbed on the magnetic plate 32 into the chip box 6.

[0041] In this way, the magnetic plate 32 generates a magnetic force that attracts free metal impurities in the water and guides them to the chip groove 13 for collection. When the annular plate 31 falls, the magnetic block 33 scrapes off the metal impurities adsorbed on the magnetic plate 32 and pushes them into the chip box 6 for storage. This automatically cleans the metal impurities in the water tank 1, reduces the long-term accumulation of metal impurities in the water tank 1, and thus improves the water quality.

[0042] Preferably, a magnetic shield 34 is provided on the outer side of the magnetic block 33, away from the side in contact with the magnetic plate 32. The magnetic shield 34 can precisely control the range of the magnetic force of the magnetic block 33, ensuring that it only produces magnetic attraction to the magnetic plate 32 without causing unnecessary interference or attraction to other non-target components or metal impurities in the water tank 1.

[0043] Reference Figure 1 and Figure 4In this embodiment, the transmission assembly 7 includes a driving wheel 71, a driven wheel 72, and a transmission belt 73. The driving wheel 71 is arranged on the screw rod 43 and rotates coaxially with the screw rod 43. The driven wheel 72 is arranged on the ultraviolet lamp 22 and rotates coaxially with the ultraviolet lamp 22. The transmission belt 73 is sleeved on the driving wheel 71 and the driven wheel 72. In this way, when the screw rod 43 rotates, the driving wheel 71 rotates accordingly and drives the driven wheel 72 to rotate through the transmission belt 73, thereby causing the ultraviolet lamp 22 to rotate around its own axis. This allows the ultraviolet lamp 22 to achieve all-round illumination when disinfecting and sterilizing the water in the water tank 1, avoiding blind spots in illumination. At the same time, the rotating design of the ultraviolet lamp 22 can also make up for the blind spots that may be caused by damage to some lamp beads or lamp tubes, and also helps to reduce the formation of biofilm on its surface, maintaining the illumination intensity of the ultraviolet lamp 22.

[0044] Reference Figure 1 In this embodiment, the water replenishment assembly 8 includes a slide bar 81, a float 82, a contact switch 83, and a normally closed control valve 84; the slide bar 81 is a cylindrical rectangular stainless steel long rod. The slide bar 81 passes through the flow hole 311 and is fixed to the inner wall of the water tank 1 along the height direction of the water tank 1. The float 82 has a certain buoyancy and can float in the water. The float 82 is slidably set on the slide bar 81 and can slide up and down with the water level in the water tank 1, but the slider cannot rotate relative to the slide bar 81. The chlorine content detector 21 is fixedly mounted on the float 82. When the water tank 1 reaches the highest water level, the buoyancy generated by the float 82 can make the chlorine content detector 21 located in the middle position of the water tank 1. The contact switch 83 is installed at the bottom of the water tank 1. A water supply port 14 connected to an external water supply pipe 100 is also provided at the bottom of the water tank 1. A normally closed control valve 84 is arranged at the water supply port 14 to control the on and off of the water supply port 14; the contact switch 83 is electrically connected to the normally closed control valve 84, and when the float 82 slides to the lowest position in the water tank 1, it can trigger the contact switch 83 to open the normally closed control valve 84.

[0045] In this way, the buoyancy generated by the float 82 positions the chlorine content detector 21 in the middle of the water tank 1, thereby ensuring that the chlorine content detector 21 is always in the optimal detection area. This avoids detection deviations caused by insufficient mixing of newly added water and pre-stored water during peak water usage periods, thereby improving the accuracy of chlorine content detection in the water. Furthermore, when the water level in the water tank 1 drops to the lowest level, the float 82 follows the water level drop and triggers the contact switch 83, which in turn controls the normally closed control valve 84 to open, allowing water from the external water supply pipe 100 to flow into the water tank 1 through the water replenishment port 14, thus achieving an automatic water replenishment function, ensuring that the water level in the water tank 1 is maintained within a reasonable range, and preventing water supply interruptions or equipment idling damage caused by excessively low water levels.

[0046] Reference Figure 1In this embodiment, a constant pressure hole 15 connected to the outside world is also opened at the top of the water tank 1; a blocking block 10 is slidably set on the slide rod 81. The blocking block 10 is made of rubber and can float on the water surface in the water tank 1. When the water tank 1 reaches the maximum water level, the blocking block 10 can block the constant pressure hole 15. In this way, when the water level in the water tank 1 drops, the blocking block 10 moves downward and opens the constant pressure hole 15, so that the air pressure inside the water tank 1 is balanced with that of the outside world, avoiding unstable water flow caused by the air pressure difference. When the water level in the water tank 1 rises to the maximum water level, the blocking block 10 will automatically block the constant pressure hole 15 as the water surface rises, preventing the water in the water tank 1 from overflowing from the constant pressure hole 15 due to excessive water pressure.

[0047] The operating principle of the secondary water supply UV disinfection system of the present embodiment is as follows: During water use, the water pump 5 draws water from the water tank 1 through the water outlet 12 and outputs it to the external water supply pipe 100. The impingement of the water on the paddle 42 drives the rotating shaft 41 to rotate. The rotating shaft 41, through the meshing of the first bevel gear 44 and the second bevel gear 45, drives the screw 43 to rotate, causing the annular plate 31 to rise along the height of the water tank 1. This effectively converts the impact force of the water flow and allows the raising and lowering of the annular plate 31 to be completed without the need for additional energy. As the annular plate 31 rises, the magnetic block 33 drives the magnetic plate 32 to move upward synchronously until the magnetic plate 32 closes the water inlet 11, thereby preventing water from the external water supply pipe 100 from entering the water tank 1 and maintaining the water in the water tank 1 in a relatively static state. At this point, the chlorine content detector 21 can accurately detect the chlorine content of the water in the water tank 1 and adjust the irradiation intensity of the UV lamp 22 based on the detection result to achieve precise disinfection and sterilization of the water in the water tank 1. When water supply is stopped, the annular plate 31 falls back to its initial position under its own weight, and the magnetic plate 32 then opens the water inlet 11, allowing the external water supply pipe 100 to begin replenishing water to the water tank 1. During its ascent and descent, the annular plate 31 scrapes away biofilm adhering to the inner wall of the water tank 1 and the outer wall of the UV lamp 22, ensuring water cleanliness and the proper functioning of the UV lamp 22. Simultaneously, as it descends, the annular plate 31 presses water flowing through the water inlet 11 downward, accelerating the mixing of new and old water within the water tank 1, improving the accuracy of chlorine content detection, and avoiding detection errors caused by water stratification. Furthermore, through the coordinated control of the chlorine content detector 21 and the UV lamp 22, the illumination of the UV lamp 22 can be flexibly adjusted based on the actual attenuation of the chlorine content in the water, ensuring effective disinfection while avoiding energy waste. Furthermore, the magnetic force generated by the magnetic plate 32 attracts free metal impurities in the water and directs them to accumulate within the chip trough 13. When the annular plate 31 falls, the magnetic block 33 can scrape off the metal impurities adsorbed on the magnetic plate 32 and push them into the chip box 6 for storage. This automatically cleans the metal impurities in the water tank 1, reducing the long-term accumulation of metal impurities in the water tank 1, thereby improving the water quality. Furthermore, when the water level in the water tank 1 drops to the lowest level, the float 82 follows the water level drop and triggers the contact switch 83, which in turn controls the normally closed control valve 84 to open, allowing water in the external water supply pipe 100 to flow into the water tank 1 through the water replenishment port 14, realizing the automatic water replenishment function, ensuring that the water level in the water tank 1 is maintained within a reasonable range, and preventing water supply interruptions or equipment idling damage caused by the low water level.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
