A large-flux reverse osmosis water purifier

Abstract

This invention discloses a high-flow reverse osmosis water purifier, relating to the field of reverse osmosis water purifier technology. After a period of use, the water pressurized by the booster pump preferentially contacts one side of the reverse osmosis filter cartridge. The amount of impurities such as silt, colloids, and scale trapped on the surface of the reverse osmosis membrane inside the cartridge increases, gradually leading to blockage and increased water flow resistance in the connecting pipe. At this point, the water inlet is disconnected to stop the raw water from entering the pre-filtration unit. Subsequently, the servo motor starts, and its output end passes through the connecting plate, driving the rotating plate to rotate 180 degrees around the rotating connection between the sealed box and the connecting plate. The rotating plate simultaneously drives the two mounting brackets fixed on one side and the reverse osmosis filter cartridges inside the brackets to rotate together, so that the pressure-bearing and non-pressure-bearing surfaces of the reverse osmosis filter cartridges are reversed, effectively reducing blockage and water flow resistance in the connecting pipe, avoiding problems such as reduced water output and slow water intake, and ensuring the advantage of high-flow water output.

Description

Technical Field

[0001] This invention relates to the field of reverse osmosis water purifier technology, and in particular to a high-flow reverse osmosis water purifier. Background Technology

[0002] With the improvement of residents' living standards, the requirements for drinking water purification are increasing. High-flow reverse osmosis water purifiers, due to their advantages such as tankless operation, instant filtration and drinking water, and large water flow, have been widely used in various scenarios such as homes and offices. Their core function relies on the high-precision filtration of RO reverse osmosis filter cartridges to effectively intercept harmful impurities in the water, such as sediment, colloids, scale, heavy metals, and microorganisms, ensuring drinking water safety. Currently, the RO reverse osmosis filter cartridges used in existing high-flow reverse osmosis water purifiers generally adopt a split structure with single-sided water inlet, single-sided pure water outlet, and side wastewater discharge. In long-term actual use, this structure has the following characteristics: during the reverse osmosis filtration process, raw water enters from the single-sided inlet end of the filter cartridge, and after filtration by the RO membrane, pure water is discharged from the single-sided pure water outlet end of the filter cartridge. The high-concentration impurities such as sediment, colloids, scale, heavy metals, and microorganisms intercepted by the membrane are discharged with the concentrated water from the wastewater discharge port on the side of the filter cartridge. During this process, due to the trapping effect of impurities, a large amount of high-concentration impurities will accumulate on the water inlet side and membrane surface of the filter element for a long time, while the pure water side, which only allows water molecules to pass through, has extremely low impurity content, resulting in a long-term severe imbalance in the impurity concentration on both sides of the filter element.

[0003] The aforementioned problems directly hinder water flow: impurities on the inlet side continuously adsorb and deposit on the surface of the reverse osmosis membrane, gradually forming a dense filter cake layer. This filter cake layer significantly reduces the water passage channels in the membrane pores, increasing the resistance to water flow. Especially for high-flow models, the water flow rate is even faster, and the high-speed water flow will more strongly wash away impurities and adhere them to the membrane surface, further accelerating membrane clogging. As the clogging intensifies, the flow channels inside the membrane module gradually narrow, and the permeation efficiency of pure water decreases significantly. This leads to a continuous decline in the purified water output flow rate of the water purifier, resulting in a noticeable decrease in water output and a slower water dispensing speed after long-term use. Summary of the Invention

[0004] The purpose of this invention is to address the problem in reverse osmosis filtration where, during the process, raw water enters from one side of the filter element, passes through the RO membrane, and pure water exits from the other side. High-concentration impurities such as sediment, colloids, scale, heavy metals, and microorganisms retained by the membrane are discharged with the concentrated water from the wastewater outlet on the side of the filter element. In this process, due to impurity retention, a large amount of high-concentration impurities accumulates on the inlet side of the filter element and the membrane surface over a long period, while the pure water side, which only allows water molecules to pass through, has extremely low impurity content. This results in a severe imbalance in impurity concentration on both sides of the filter element. Therefore, this invention proposes a high-flow-rate reverse osmosis water purifier.

[0005] To achieve the above objectives, the present invention employs the following technology: a high-flow reverse osmosis water purifier includes a water purifier body and a pre-filter unit, a reverse osmosis filter unit, and a post-filter unit installed inside the water purifier body. The pre-filter unit and the reverse osmosis filter unit are connected by a connecting pipe, and the reverse osmosis filter unit and the post-filter unit are also connected by a connecting pipe. The purifier also includes a reverse osmosis filter assembly and an adjustment assembly disposed inside the reverse osmosis filter unit. The reverse osmosis filtration assembly includes a closed box connected between two connecting pipes. A connecting plate is connected to the outer periphery of the closed box by several connecting frames. A rotating plate is rotatably connected between the closed box and the connecting plate. A servo motor is installed on one side of the connecting plate, and the output end of the servo motor passes through the connecting plate and is connected to the rotating plate. Two mounting frames are fixed on one side of the rotating plate, and reverse osmosis filter cartridges are installed inside the mounting frames. A drain pipe is installed on the outer periphery of the closed box. Start the servo motor. The output of the servo motor drives the rotating plate to rotate, and simultaneously drives the reverse osmosis filter cartridge connected to the mounting bracket to rotate 180 degrees.

[0006] As a further description of a high-flow reverse osmosis water purifier based on the above technology: Two symmetrical grooves are formed on the outer periphery of the rotating plate, and a sealing gasket is installed between the rotating plate and the enclosed box.

[0007] As a further description of a high-flow reverse osmosis water purifier based on the above technology: The adjustment assembly includes a fixed plate fixedly connected inside the two connecting pipes. Several extension rods are fixedly fixed to the top of the fixed plate. A lifting plate is slidably connected to the outer periphery of the extension rods. A telescopic spring is sleeved on the outer periphery of each extension rod. A water pipe is fixed inside the lifting plate.

[0008] As a further description of a high-flow reverse osmosis water purifier based on the above technology: One of the water pipes has an internal flow port, and the other water pipe has several outlets on its outer periphery and is closed at the bottom.

[0009] As a further description of a high-flow reverse osmosis water purifier based on the above technology: The outer periphery of the connecting pipe is provided with a lifting groove, and the outer periphery of the lifting plate is connected to an extension plate extending out of the connecting pipe. The extension plate is slidably connected to the lifting groove. The outer periphery of the extension plate is connected to a closing plate that closes the lifting groove. The bottom of the extension plate is fixed with an abutment rod that contacts the groove.

[0010] As a further description of a high-flow reverse osmosis water purifier based on the above technology: The fixing plate and the connecting pipe are both provided with three sliding grooves inside. The side of the sealing plate is fixed with a collar that surrounds the connecting pipe. Several mounting plates are installed on the outer periphery of the collar, and the mounting plates are provided with inclined grooves inside.

[0011] As a further description of a high-flow reverse osmosis water purifier based on the above technology: Each of the grooves has a slider and a sealing plate slidably connected inside. A connecting tube extends from one side of the slider, and mounting rods that contact the inclined groove are fixed on both sides of the slider.

[0012] As a further description of a high-flow reverse osmosis water purifier based on the above technology: The pre-filter unit is connected to a water inlet, and a booster pump is installed on the connecting pipe. The bottom of the post-filter unit is connected to a water outlet.

[0013] In summary, due to the adoption of the above-mentioned technology in this high-flow reverse osmosis water purifier, the beneficial effects of this invention are: By using the reverse osmosis filtration components and adjustment components, after the reverse osmosis filter cartridge in the filtration station has been used for a period of time, the water pressurized by the booster pump will first come into contact with one side of the reverse osmosis filter cartridge because the connecting pipe connected to the booster pump is the inlet end. As a result, the amount of impurities such as silt, colloids, and scale trapped on the surface of the reverse osmosis membrane inside the cartridge will increase, gradually leading to blockage. This will increase the water flow resistance in the connecting pipe. At this time, the water inlet will be disconnected to stop the raw water from entering the pre-filtration unit. Then, the servo motor will start, and its output end will pass through the connecting plate, driving the rotating plate to rotate 180 degrees around the rotating connection between the closed box and the connecting plate. The rotating plate will simultaneously drive the two mounting brackets fixed on one side and the reverse osmosis filter cartridge inside the brackets to rotate together, so that the pressure surface and the non-pressure surface of the reverse osmosis filter cartridge will be reversed. This will effectively reduce the blockage, reduce the water flow resistance in the connecting pipe, and avoid problems such as reduced water output and slower water intake, thus ensuring the advantage of high-flow-rate water output. By repositioning the reverse osmosis filter cartridges so that the clean end with lower impurity content is the inlet water face, after the water supply is restored, the raw water pressurized by the booster pump will first contact the clean end face and slowly permeate and divert, instead of directly flushing the highly polluted area where the concentrate is retained. This fundamentally prevents large particles and colloids from accumulating on one side of the core membrane surface of the reverse osmosis filter cartridge. At the same time, because the sealed box has a circular structure, the pressurized water will quickly fill the entire sealed box after contacting one side of the reverse osmosis filter cartridge and filter evenly along the surface of the reverse osmosis filter cartridge. The water flow achieves uniform dispersion and diversion within the sealed box, and impurities diffuse with the water flow to the entire reverse osmosis filter cartridge cavity, further preventing local accumulation of pollutants, delaying membrane clogging, and extending the service life of the reverse osmosis filter cartridge. When the servo motor drives the rotating plate to rotate, the abutment rod that contacts the groove on the surface of the rotating plate moves along the inner wall of the groove and the surface of the rotating plate. When the abutment rod moves out of the groove and contacts the surface of the rotating plate, it simultaneously drives the extension plate to slide up in the lifting groove of the connecting pipe. The sealing plate also moves up at the same time. When the extension plate moves up, it drives the lifting plate to slide up on the outer periphery of the extension rod and stretches the telescopic spring. At the same time, it pulls the two water pipes up to one side of the fixed plate, so that the water pipes are separated from the clean water pipes inside the reverse osmosis filter cartridge, disconnecting the clean water channel and avoiding clean water leakage during the switching process. At the same time, the upward movement of the sealing plate causes the collar surrounding the connecting pipe on the side to move upward. The collar causes several mounting plates on the outer periphery to move upward synchronously. The mounting rod, which contacts the inclined groove inside the mounting plate, pushes the slider and sealing plate to slide along the sliding groove inside the fixed plate and the connecting pipe under the guidance of the inclined groove. Finally, the three sealing plates fit together to form a closed structure, which can effectively prevent sewage containing high concentrations of impurities in the sealed box from entering the connecting pipe, avoid contaminating subsequent pipelines and components, and ensure the safety of the effluent water quality. After the reverse osmosis filter cartridge is reversed, the servo motor continues to drive the rotating plate to rotate 180 degrees. Once in position, the abutment rod aligns with the groove again, the stretched spring rebounds, pulling the lifting plate down along the extension rod. This causes the extension plate to move downwards, allowing the abutment rod to re-engage in the groove. As the extension plate moves downwards, it simultaneously lowers the sealing plate, collar, and mounting plate. During the descent of the mounting plate, the inclined groove guides the mounting rod to move, causing the slider and sealing plate to slide along the groove. This allows the sealing plate to move out of the opening in the middle of the fixed plate, releasing the flow channel seal. At the same time, the lifting plate moves the two water pipes downwards, tightly fitting them against the end face of the purified water pipe inside the rotated reverse osmosis filter cartridge. This creates a connecting channel between the purified water pipe and the water pipe's flow port, ensuring smooth water flow. This allows the entire machine to quickly resume normal filtration after switching without manual intervention, improving ease of use. Attached Figure Description

Detailed Implementation

[0016] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a high-flow reverse osmosis water purifier according to the present invention in a clear and complete manner. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1-11 As shown, the present invention provides a high-flow reverse osmosis water purifier: including a water purifier body 11 and a pre-filter unit 12, a reverse osmosis filter unit 13 and a post-filter unit 14 installed inside the water purifier body 11. The water purifier body 11 is prior art, so it will not be described in detail. The pre-filter unit 12 and the reverse osmosis filter unit 13 are connected by a connecting pipe 16. The reverse osmosis filter unit 13 and the post-filter unit 14 are also connected by a connecting pipe 16. The pre-filter unit 12 is connected to an inlet 15. A booster pump 17 is installed on the connecting pipe 16. The bottom of the post-filter unit 14 is connected to an outlet 18. It also includes a reverse osmosis filter assembly 20 and an adjustment assembly 30 disposed inside the reverse osmosis filter unit 13. Tap water enters the pre-filter unit 12 through the inlet 15. After coarse filtration (intercepting large particles of silt, suspended solids, and other impurities) by the pre-filter unit 12, it is transported to the booster pump 17 through the connecting pipe 16. The booster pump 17 starts working and mechanically pressurizes the water after pre-filtration, increasing the pressure of the low-pressure raw water to the working pressure required for reverse osmosis filtration. Then, the high-pressure water flows through the connecting pipe 16 into the reverse osmosis filter component 20 inside the reverse osmosis filter unit 13. After high-precision filtration by the reverse osmosis filter component 20, harmful impurities such as colloids, scale, heavy metals, and microorganisms in the water are removed. The resulting pure water is transported to the post-filter unit 14 through the connecting pipe 16. After the post-filter unit 14 improves the taste and performs secondary antibacterial treatment, it is finally discharged through the outlet 18 for direct use by users. The concentrated water (containing the intercepted high-concentration impurities) generated during the filtration process is discharged through the drain pipe 26 on the outer periphery of the sealed box 21.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the reverse osmosis filter assembly 20 includes a closed box 21 connected between two connecting pipes 16. A connecting plate 212 is connected to the outer periphery of the closed box 21 by several connecting brackets 211. A rotating plate 22 is rotatably connected between the closed box 21 and the connecting plate 212. Two symmetrical grooves 221 are opened on the outer periphery of the rotating plate 22. A sealing gasket is installed on one side of the rotating plate 22 and is rotatably embedded in the closed box 21. A servo motor 23 is installed on one side of the connecting plate 212, and the output end of the servo motor 23 passes through the connecting plate 212 and is connected to the rotating plate 22. Two mounting brackets 24 are fixed on one side of the rotating plate 22. A reverse osmosis filter cartridge 25 is installed inside the mounting bracket 24. A clean water pipe is connected inside the reverse osmosis filter cartridge 25. A sewage pipe 26 is installed on the outer periphery of the closed box 21. After the reverse osmosis filter cartridge 25 in the filtration station has been used for a period of time, since the connecting pipe 16 connected to the booster pump 17 is the water inlet, the water pressurized by the booster pump 17 will first come into contact with one side of the reverse osmosis filter cartridge 25. As the filtration process continues, the amount of impurities such as silt, colloids, and scale trapped on the surface of the reverse osmosis membrane inside the reverse osmosis filter cartridge 25 will increase, gradually leading to a blockage trend. The water flow resistance in the connecting pipe 16 will also increase. At this time, the water inlet 15 will be disconnected to stop the raw water from entering the pre-filtration unit 12. Then, the servo motor 23 will be started, and the output end of the servo motor 23 will pass through the connecting plate 2. 12 drives the rotating plate 22 to rotate 180 degrees around the rotating connection between the closed box 21 and the connecting plate 212. When the servo motor 23 receives the 180-degree rotation command, the driver will adjust the output in real time according to the encoder feedback, so that the servo motor 23 stops accurately at the target position. The rotating plate 22 synchronously drives the two mounting brackets 24 fixed on one side and the reverse osmosis filter cartridge 25 installed inside the mounting bracket 24 to rotate together, thereby causing the unpressurized side of the reverse osmosis filter cartridge 25 in the filtration position to switch directions with the pressurized side, thereby reducing the clogging of the reverse osmosis filter cartridge 25 and reducing the water flow resistance in the connecting pipe 16. By altering the assembly position of the reverse osmosis filter cartridge 25, the clean end with lower impurity content becomes the inlet water facing surface. After the inlet water is restored, the raw water pressurized by the booster pump 17 will first contact the clean end face of the reverse osmosis filter cartridge 25 and slowly permeate and divert. The raw water no longer directly flushes the highly polluted area where the concentrate is retained in the reverse osmosis filter cartridge 25, preventing large particles and colloids in the water from accumulating on one side of the core membrane surface of the reverse osmosis filter cartridge 25. At the same time, since the sealed box 21 has a circular structure, the water pressurized by the booster pump 17 will quickly fill the interior of the sealed box 21 after contacting one side of the reverse osmosis filter cartridge 25. At this time, the pressurized water will also be evenly filtered along the surface of the reverse osmosis filter cartridge 25. The water flow achieves uniform dispersion and diversion inside the sealed box 21, and impurities slowly diffuse with the water flow into the entire cavity of the reverse osmosis filter cartridge 25, effectively preventing pollutants from accumulating in local areas of the reverse osmosis filter cartridge 25, further delaying clogging, and ensuring smooth water flow.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11As shown, the adjusting assembly 30 includes a fixed plate 31 fixedly connected inside the two connecting pipes 16. Several extension rods 311 are fixed to the top of the fixed plate 31. A lifting plate 312 is slidably connected to the outer periphery of the extension rods 311. A telescopic spring 314 is sleeved on the outer periphery of each extension rod 311. A water pipe 313 is fixed inside the lifting plate 312. One water pipe 313 has a flow port inside, and the other water pipe 313 has several outlets on its outer periphery and is closed at the bottom. A lifting groove 32 is formed on the outer periphery of the connecting pipes 16, and an extension plate 321 extending out of the connecting pipes 16 is connected to the outer periphery of the lifting plate 312. The extension plate 321 and the lifting groove 32... The extension plate 321 is connected to the sealing plate 322 of the closed lifting groove 32. The bottom of the extension plate 321 is fixed with an abutment rod 323 that contacts the groove 221. The fixed plate 31 and the connecting pipe 16 are both provided with three sliding grooves 33. The side of the sealing plate 322 is fixed with a collar 34 that surrounds the connecting pipe 16. Several mounting plates 341 are installed on the outer periphery of the collar 34. The mounting plates 341 are provided with inclined grooves 342. The sliding plate 35 and the sealing plate 351 are slidably connected inside each sliding groove 33. The connecting pipe 16 extends out from one side of the slider 35. The two sides of the slider 35 are fixed with mounting rods 352 that contact the inclined grooves 342. After being pressurized by the booster pump 17, the water flows through the water pipe 313 inside the connecting pipe 16 and flows out from several outlets opened on the outer periphery of the water pipe 313. Then, the pressurized water comes into full contact with the reverse osmosis filter cartridge 25 in the filtration station. The purified water after being filtered by the reverse osmosis filter cartridge 25 flows out through the purified water pipe inside it, and then flows through the flow port opened inside another water pipe 313. Finally, it is transported to the post-filtration unit 14 through the connecting pipe 16 to complete the subsequent taste improvement treatment. When the servo motor 23 drives the rotating plate 22 to rotate, the abutment rod 323, which is in contact with the groove 221 on the surface of the rotating plate 22, will move synchronously along the inner wall of the groove 221 and the surface of the rotating plate 22. When the abutment rod 323 moves from the groove 221 to the surface of the rotating plate 22 as the rotating plate 22 rotates, the abutment rod 323 will move upward and synchronously drive the extension plate 321, which is fixedly connected to it, to slide upward in the lifting groove 32 opened in the connecting pipe 16. At the same time, the closing plate 322, which is fixedly connected to the extension plate 321, will also move upward synchronously. As the extension plate 321 moves upward, it will cause the lifting plate 312 to slide upward on the outer periphery of the extension rod 311, and simultaneously stretch the telescopic spring 314 sleeved on the outer periphery of the extension rod 311. As the lifting plate 312 moves upward, it will simultaneously pull the two water pipes 313 fixedly connected to it to move upward together until the water pipes 313 move to one side of the fixed plate 31, so that the two water pipes 313 are separated from the contact with the internal water purification pipe of the reverse osmosis filter cartridge 25, and the water purification flow channel is disconnected. At the same time, when the sealing plate 322 moves upward, it will simultaneously drive the collar 34 fixed on its side and surrounding the connecting pipe 16 to move upward together. The collar 34 will then drive several mounting plates 341 fixed on its outer periphery to move upward simultaneously. The mounting rod 352, which is in contact with the inclined groove 342 opened inside the mounting plate 341, will push the slider 35 and the sealing plate 351 fixedly connected to the slider 35 to slide along the sliding groove 33 opened inside the fixed plate 31 and the connecting pipe 16 under the inclined guiding action of the inclined groove 342. Finally, the three sealing plates 351 will fit together to form a closed structure, effectively preventing sewage containing high concentration of impurities in the sealed box 21 from entering the connecting pipe 16 and avoiding sewage pollution of subsequent pipelines and components. After the reverse osmosis filter cartridge 25 has completed its orientation change, the servo motor 23 continues to drive the rotating plate 22 to rotate 180 degrees. After the rotation is in place, the abutment rod 323, which moves along the outer periphery of the rotating plate 22, will once again align with and contact the groove 221 on the surface of the rotating plate 22. At this time, the tension spring 314, which is in a stretched state, begins to rebound. Under the elastic force, it pulls the lifting plate 312 to slide down along the extension rod 311. As the lifting plate 312 moves down, it drives the extension plate 321 to move down synchronously, so that the abutment rod 323 is re-engaged into the groove 221 of the rotating plate 22, thereby limiting and fixing the rotating plate 22. When the extension plate 321 moves downward, it will simultaneously drive the sealing plate 322 and the collar 34 connected to its outer periphery to descend together. The collar 34 will then drive the mounting plate 341 to move downward in sync. During the descent of the mounting plate 341, the inclined groove 342 will guide the mounting rod 352 in contact with it to move, thereby driving the slider 35 and the sealing plate 351 to slide along the sliding groove 33, so that the sealing plate 351 moves out of the opening in the middle of the fixed plate 31, releasing the blockage of the flow channel of the connecting pipe 16. At the same time, when the lifting plate 312 descends, it will drive the two water pipes 313 to move downward in sync, moving out of the area blocked by the sealing plate 351, and finally tightly fitting with the end face of the clean water pipe inside the rotated reverse osmosis filter cartridge 25, so that the clean water pipe and the flow port inside the water pipe 313 form a communication channel, which facilitates the smooth flow of filtered clean water and ensures the normal filtration operation of the whole machine.

[0020] Working principle: After the reverse osmosis filter cartridge 25 in the filtration station has been used for a period of time, since the connecting pipe 16 connected to the booster pump 17 is the water inlet, the pressurized water first contacts one side of the reverse osmosis filter cartridge 25. The impurities trapped on the surface of the reverse osmosis membrane inside it continue to increase, gradually causing blockage and increasing the water flow resistance in the connecting pipe 16. At this time, the water inlet 15 is disconnected to stop the raw water from entering the pre-filtration unit 12. Then the servo motor 23 is started, and its output end passes through the connecting plate 212, driving the rotating plate 22 to rotate 180 degrees around the connection between the closed box 21 and the connecting plate 212. The rotating plate 22 simultaneously drives the two mounting brackets 24 fixed on one side and the reverse osmosis filter cartridge 25 inside the bracket to rotate, so that the pressure surface and the non-pressure surface of the reverse osmosis filter cartridge 25 are reversed, reducing blockage and reducing water flow resistance. By changing the assembly position of the reverse osmosis filter cartridge 25, the clean end with fewer impurities is made as the water inlet face. After the water inlet is restored, the raw water pressurized by the booster pump 17 first contacts the clean end face and slowly permeates and flows out, no longer directly flushing the highly polluted area where the concentrate is intercepted. This avoids the accumulation of large particles and colloids on one side of its core membrane surface. At the same time, because the closed box 21 has a circular structure, after the pressurized water contacts one side of the reverse osmosis filter cartridge 25, it will quickly fill the entire closed box 21 and filter evenly along the surface of the reverse osmosis filter cartridge 25. The water flow is evenly dispersed and distributed in the closed box 21, and impurities diffuse with the water flow to the entire cavity of the reverse osmosis filter cartridge 25, avoiding local accumulation of pollutants and further delaying clogging. During normal filtration, the water pressurized by the booster pump 17 flows along the water pipe 313 inside the connecting pipe 16 and flows out from the outlet on the outer periphery of the water pipe 313, making full contact with the reverse osmosis filter cartridge 25 of the filtration station. The filtered clean water flows out through the clean water pipe inside the reverse osmosis filter cartridge 25, and is transported to the post-filtration unit 14 through the flow port inside another water pipe 313 and the connecting pipe 16, thus completing the taste improvement. When the servo motor 23 drives the rotating plate 22 to rotate, the abutment rod 323, which is in contact with the groove 221 on the surface of the rotating plate 22, moves along the inner wall of the groove 221 and the surface of the rotating plate 22. When the abutment rod 323 moves out of the groove 221 and contacts the surface of the rotating plate 22, it simultaneously drives the extension plate 321 to slide up in the lifting groove 32 of the connecting pipe 16. The sealing plate 322 also moves up simultaneously. When the extension plate 321 moves up, it drives the lifting plate 312 to slide up on the outer periphery of the extension rod 311 and stretch the telescopic spring 314. The lifting plate 312 simultaneously pulls the two water pipes 313 up to one side of the fixed plate 31, so that the water pipes 313 are separated from the clean water pipe inside the reverse osmosis filter cartridge 25 and the clean water channel is disconnected. At the same time, the upward movement of the sealing plate 322 causes the collar 34 surrounding the connecting pipe 16 on the side to move upward. The collar 34 causes several mounting plates 341 on the outer periphery to move upward synchronously. The mounting rod 352, which is in contact with the inclined groove 342 inside the mounting plate 341, pushes the slider 35 and the sealing plate 351 to slide along the sliding groove 33 inside the fixed plate 31 and the connecting pipe 16 under the guidance of the inclined groove 342. Finally, the three sealing plates 351 fit together to form a closed structure, preventing sewage in the closed box 21 from entering the connecting pipe 16. After the reverse osmosis filter cartridge 25 is reversed, the servo motor 23 continues to drive the rotating plate 22 to rotate 180 degrees. When the servo motor 23 receives the 180-degree rotation command, the driver will adjust the output in real time according to the encoder feedback so that the servo motor 23 stops accurately at the target position. After the rotation is in place, the abutment rod 323 aligns with the groove 221 again. The tension spring 314 in the stretched state rebounds and pulls the lifting plate 312 down along the extension rod 311, causing the extension plate 321 to move down, so that the abutment rod 323 is re-engaged in the groove 221. When the extension plate 321 moves down, it simultaneously drives the sealing plate 322, the collar 34, and the mounting plate 341 to descend. During the descent of the mounting plate 341, the inclined groove 342 guides the mounting rod 352 to move, causing the slider 35 and the sealing plate 351 to slide along the sliding groove 33, so that the sealing plate 351 moves out of the middle opening of the fixed plate 31, releasing the flow channel seal. At the same time, the lifting plate 312 drives the two water pipes 313 to move down, leaving the sealed area and fitting with the end face of the purified water pipe inside the rotated reverse osmosis filter cartridge 25, so that the purified water pipe and the flow port of the water pipe 313 form a connecting channel, ensuring smooth flow of purified water and ensuring normal filtration of the whole machine.
