Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a water storage tank with filtration and sterilization functions. Background Technology

[0002] With increasingly higher requirements for the quality of domestic and industrial water, water storage tanks, as key equipment for water storage, are receiving more and more attention for their water purification and sterilization functions. Traditional water storage tanks often only have simple storage functions and lack effective treatment mechanisms for the water entering the tank. This means that large particulate impurities, residual chlorine, odors, and various microorganisms that may be present in the water cannot be properly removed, thus affecting the safety and quality of water use.

[0003] In the application of existing water treatment technologies to water storage tanks, although some water storage tanks are equipped with some filtration or sterilization devices, for example, in the filtration stage, some equipment cannot effectively slow down the water flow, causing the water flow to concentrate and impact the filter components. This not only easily damages the filter structure, but also greatly reduces the filtration effect. Large particles of impurities cannot be fully intercepted, and the filter components are easily clogged due to the accumulation of impurities, affecting their service life and filtration efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a water storage tank with filtration and sterilization functions, solving the problem that filter components are easily clogged due to the accumulation of impurities.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a water storage tank with filtration and sterilization functions, comprising: a tank body, wherein a support leg is fixedly connected to the bottom of the tank body, an inspection door is fixedly connected to the outer wall of the tank body by bolts, a water inlet pipe is fixedly connected to the top of the tank body, and a drain pipe is fixedly connected to the bottom of the tank body; a water treatment device, wherein the outer side of the water treatment device is fixedly connected to the inner wall of the tank body, an electrode plate is fixedly connected to the bottom of the water treatment device, the water treatment device includes a filter assembly, an adsorption assembly is fixedly connected to the bottom of the filter assembly, and the bottom of the adsorption assembly slides... The system is connected to a partition plate, with a drive motor fixedly connected to the center of the partition plate. An ultraviolet germicidal lamp is fixedly connected to the inner side of the partition plate. Water enters the tank through the inlet pipe at the top of the tank and then enters the filter component of the water treatment device for initial filtration to remove large particulate impurities. Next, it flows into the adsorption component, which removes residual chlorine, odors, and some organic pollutants from the water through adsorption. Subsequently, the water flows to the area below the partition plate inside the tank. During this process, the drive motor provides power for the operation of the filter component, while the ultraviolet germicidal lamp sterilizes the water by emitting ultraviolet light to destroy the DNA structure of microorganisms.

[0008] The filter assembly includes a protective shell, an annular filter screen is fixedly connected to the inner side of the protective shell, a drain pipe is fixedly connected to the outer side of the annular filter screen, a flow-slowing component is rotatably connected to the inner side of the protective shell, and an arc-shaped scraper is fixedly connected to the outer side of the flow-slowing component. A drive motor drives the arc-shaped scraper to rotate through the rotating shell in the flow-slowing component. During the rotation, the arc-shaped scraper scrapes off the impurities accumulated on its surface, causing them to flow downwards along the gap between the annular filter screen and the annular plate, and finally deposit at the bottom of the protective shell.

[0009] The flow-slowing component includes a rotating shell, a hollow slide rod slidably connected to the inner side of the rotating shell, a connecting pipe slidably connected to the inner side of the hollow slide rod, a water inlet shell slidably connected to the top of the connecting pipe, a conical diverter block fixedly connected to the top of the hollow slide rod, an annular plate fixedly connected to the outer wall of the rotating shell, and a tension spring fixedly connected to the inner side of the rotating shell. The bottom of the tension spring is fixedly connected to the bottom of the hollow slide rod. When the water flowing out from the water inlet pipe impacts the conical diverter block, the conical diverter block drives the hollow slide rod to slide into the rotating shell under the impact of the water flow. At this time, the tension spring is stretched, thereby buffering the large instantaneous impact force brought by the water flow and preventing the impact force from being directly transmitted to other components and causing structural damage.

[0010] Preferably, the outer side of the electrode plate is fixedly connected to the inner wall of the tank, the inner wall of the tank is fixedly connected to the outer wall of the partition plate, the outer wall of the filter assembly is fixedly connected to the top of the inner wall of the tank, the output end of the drive motor is fixedly connected to the bottom of the filter assembly, the adsorption assembly is arranged in a ring along the central axis of the partition plate, and the electrode plate generates strong oxidizing substances by means of electrolysis reaction, which further kills residual microorganisms in the water, thus ensuring that the water is fully purified and sterilized.

[0011] Preferably, the outer wall of the protective shell is fixedly connected to the top of the inner wall of the tank, the outer wall of the drain pipe is fixedly connected to the inner wall of the protective shell, the outer side of the arc-shaped scraper is slidably connected to the inner side of the protective shell, the bottom of the slow-flow component is fixedly connected to the output end of the drive motor, the outer side of the rotating shell is rotatably connected to the inner side of the protective shell, the outer wall of the rotating shell is fixedly connected to the center of the arc-shaped scraper, the inner side of the conical diverting block is slidably connected to the outer wall of the connecting pipe, and the outer wall of the water inlet shell is fixedly connected to the top of the inner wall of the tank. The relatively stable and gentle water flow environment created by the continuous rotation of the annular plate can prevent the water flow from forming a turbulent flow or generating a large vortex at the bottom of the protective shell due to excessive impact force, so that the water flow at the bottom of the protective shell remains in a relatively stable and slow flow state, allowing impurities to be deposited steadily at the bottom.

[0012] Preferably, the adsorption assembly includes a support frame, a flow-blocking component fixedly connected to the top of the support frame, a positioning component fixedly connected to the bottom of the support frame, an activated carbon cylinder movably installed at the bottom of the flow-blocking component, the bottom of the activated carbon cylinder contacting the top of the positioning component, and the top of the flow-blocking component fixedly connected to the bottom of the protective shell. The activated carbon cylinder removes residual chlorine, odors, and some organic pollutants from the water through its adsorption properties, thus achieving further water purification.

[0013] Preferably, the positioning component includes a fixed ring, an internally threaded ring rotatably connected to the inner side of the fixed ring, a knob fixedly connected to the bottom of the internally threaded ring, a guide tube threadedly connected to the inner side of the internally threaded ring, and a limit plate fixedly connected to the top of the guide tube. After removing the bolts fixing the inspection door on the tank, the knob in the positioning component is rotated to make the internally threaded ring rotate within the fixed ring.

[0014] Preferably, the outer side of the fixing ring is fixedly connected to the bottom of the support frame, the outer side of the limiting plate is slidably connected to the inner side of the support frame, the top of the limiting plate is in contact with the bottom of the activated carbon cylinder, and when the internal threaded ring rotates inside the fixing ring, the guide tube drives the limiting plate to slide downward under the limiting action of the support frame, thereby increasing the distance between the limiting plate and the flow-blocking component.

[0015] Preferably, the flow-blocking component includes a sealing ring, a compression spring is fixedly connected to the outer side of the sealing ring, a sliding cylinder is fixedly connected to the bottom end of the compression spring, a connecting rod is fixedly connected to the top of the sliding cylinder, and a flow-blocking block is fixedly connected to the top of the connecting rod. The activated carbon cylinder moves downward together with the limiting plate. During this process, the compression spring gradually releases its elastic force, causing the sliding cylinder to slide downward along the inner side of the sealing ring, which in turn causes the connecting rod to drive the flow-blocking block to slide downward.

[0016] Preferably, the outer side of the sealing ring is fixedly connected to the top of the support frame, the outer side of the sliding cylinder is slidably connected to the inner side of the sealing ring, the bottom of the flow-blocking block is in contact with the top of the sealing ring, and the bottom of the sliding cylinder is in contact with the top of the activated carbon cylinder. When the flow-blocking block contacts the sealing ring, the flow of water can be blocked.

[0017] (III) Beneficial Effects

[0018] This invention provides a water storage tank with filtration and sterilization functions. It has the following beneficial effects:

[0019] (i) The water storage tank undergoes initial filtration through the filter components in the water treatment device to remove large particulate impurities; then it flows into the adsorption components, which remove residual chlorine, odors, and some organic pollutants from the water through adsorption; subsequently, the water flows to the area below the partition plate inside the tank, during which the drive motor provides power for the operation of the filter components, while the ultraviolet germicidal lamp sterilizes by emitting ultraviolet light to destroy the DNA structure of microorganisms in the water; finally, the electrode plate generates strong oxidizing substances through electrolysis to further kill residual microorganisms in the water, thus ensuring that the water is fully purified and sterilized.

[0020] (ii) The water storage tank uses a filter assembly. After the water enters the filter assembly, it first passes through a slow-flow component to disperse and slow the water flow, so that it flows evenly to the annular filter screen. The annular filter screen intercepts large particles of impurities in the water to achieve preliminary filtration. Then the filtered water flows through the protective shell into the adsorption assembly.

[0021] (III) The water storage tank uses a flow-slowing component to drive the motor to rotate the arc-shaped scraper through the rotating shell in the flow-slowing component. During the rotation, the arc-shaped scraper scrapes off the impurities accumulated on its surface, causing them to flow downwards along the gap between the annular filter screen and the annular plate, and finally settle at the bottom of the protective shell. The impurities are discharged through the drain pipe, keeping the mesh of the annular filter screen unobstructed, thereby ensuring that the annular filter screen continues to play its filtering role and maintains good filtration efficiency.

[0022] (iv) The water storage tank uses a flow-slowing component. When the water flowing out from the inlet pipe impacts the conical diverter block, the conical diverter block moves the hollow slide rod into the rotating shell under the impact of the water flow. At this time, the tension spring is stretched, which can buffer the large instantaneous impact force brought by the water flow and prevent the impact force from being directly transmitted to other components and causing structural damage. At the same time, the conical diverter block rotates with the rotating shell through the hollow slide rod. The conical diverter block initially receives the impact of the water flow and uses its own arc-shaped protrusion to change the direction of the water flow, dispersing it and making it flow evenly to the annular filter screen.

[0023] (v) The water storage tank, through the ring plate, creates a relatively stable and gentle water flow environment through continuous rotation of the ring plate. This can prevent the water flow from forming a turbulent flow or generating a large vortex at the bottom of the protective shell due to excessive impact force. This keeps the water flow at the bottom of the protective shell relatively stable and slow, allowing impurities to settle steadily at the bottom and wait to be discharged through the drain pipe. This effectively ensures that impurities will not be stirred up again during the entire filtration process, maintaining the stable and efficient filtration operation of the filter components.

[0024] (vi) The water storage tank uses an adsorption component. After the water flows into the adsorption component, it first comes into contact with the flow-blocking component. Then the water flows slowly through the interior of the activated carbon cylinder. Relying on the adsorption performance of the activated carbon in the activated carbon cylinder, residual chlorine, odor and some organic pollutants in the water are removed, thus achieving further purification of the water. The purified water is then discharged to the bottom of the tank through the positioning component.

[0025] (vii) When the activated carbon cylinder needs to be replaced, the bolts fixing the inspection door on the tank body are first removed by the positioning component. Then, the knob in the positioning component is turned so that the internal thread ring rotates in the fixed ring. At this time, under the limiting action of the support frame, the guide pipe drives the limiting plate to slide down, thereby increasing the distance between the limiting plate and the flow obstruction component, so as to facilitate the removal of the activated carbon cylinder.

[0026] (viii) The water storage tank, through the flow-blocking component, allows the activated carbon cylinder to move downwards along with the limiting plate. During this process, the compression spring gradually releases its elasticity, causing the sliding cylinder to slide downwards along the inner side of the sealing ring. This, in turn, causes the connecting rod to drive the flow-blocking block to slide downwards. When the flow-blocking block contacts the sealing ring, it can block the flow of water, preventing water from continuing to flow into the area when the activated carbon cylinder is replaced. This prevents water leakage and ensures that the replacement operation is not affected by water flow interference, thus ensuring that the entire replacement process can be carried out safely and orderly.

[0027] (ix) The water storage tank utilizes an adsorption assembly. Within this assembly, each activated carbon cartridge is independently mounted on a support frame, and each cartridge is positioned and constrained by a corresponding positioning component. When a cartridge needs to be replaced, the corresponding positioning component is operated. For other cartridges not requiring replacement, their respective positioning components, flow-blocking components, and other components remain in their original state, ensuring that water can flow normally through the corresponding cartridge for adsorption and purification. This achieves the effect of replacing one activated carbon cartridge without affecting the normal operation of other adsorption components.

[0028] (x) When it is necessary to clean the impurities deposited at the bottom of the protective shell through the drain pipe of the water storage tank, the activated carbon cylinder can be removed first. At this time, the flow-blocking component can block the flow of water. Then, the drain pipe is opened, and water is injected into the connecting pipe through the water inlet shell, so that the water flows into the rotating shell and finally flows out from the bottom of the annular plate along the rotating shell. At this time, the outflowing water can carry the impurities deposited at the bottom of the annular plate out of the drain pipe, ensuring the cleanliness of the internal environment of the filter component and helping to maintain the good filtration performance of the filter component.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0040] Example: Please refer to Figure 1 - Figure 9 The present invention provides a technical solution: a water storage tank with filtration and sterilization function, comprising:

[0041] The tank body 1 has a support leg 2 fixedly connected to its bottom. An inspection door 3 is fixedly connected to the outer wall of the tank body 1 by bolts. A water inlet pipe 4 is fixedly connected to the top of the tank body 1. A drain pipe 5 is fixedly connected to the bottom of the tank body 1. The water storage tank is composed of the tank body 1, support leg 2, inspection door 3, water inlet pipe 4, drain pipe 5, and water treatment device 6. Its core water treatment process mainly relies on the water treatment device 6. The internal components of the water treatment device 6 work together to filter, adsorb, and sterilize the water entering the tank body 1 from the water inlet pipe 4 in sequence. The finally treated water can be discharged through the drain pipe 5 for use.

[0042] A water treatment device 6 is fixedly connected to the inner wall of a tank 1 on its outer side. An electrode plate 7 is fixedly connected to the bottom of the water treatment device 6. The water treatment device 6 includes a filter assembly 61, an adsorption assembly 62 fixedly connected to the bottom of the filter assembly 61, a partition plate 63 slidably connected to the bottom of the adsorption assembly 62, a drive motor 64 fixedly connected to the center of the partition plate 63, and an ultraviolet germicidal lamp 65 fixedly connected to the inner side of the partition plate 63. The outer side of the electrode plate 7 is fixedly connected to the inner wall of the tank 1, the inner wall of the tank 1 is fixedly connected to the outer wall of the partition plate 63, the outer wall of the filter assembly 61 is fixedly connected to the top of the inner wall of the tank 1, and the output end of the drive motor 64 is fixedly connected to the bottom of the filter assembly 61. The adsorption assembly 62... Arranged in a ring along the central axis of the partition plate 63, water enters the tank 1 through the inlet pipe 4 at the top of the tank body 1, and then enters the filter component 61 in the water treatment device 6 for initial filtration to remove large particulate impurities; then it flows into the adsorption component 62, which removes residual chlorine, odors and some organic pollutants in the water through adsorption; then the water flows to the area below the partition plate 63 in the tank body 1, during which the drive motor 64 provides power for the operation of the filter component 61, while the ultraviolet germicidal lamp 65 sterilizes by emitting ultraviolet light to destroy the DNA structure of microorganisms in the water; finally, the electrode plate 7 generates strong oxidizing substances through electrolysis to further kill residual microorganisms in the water, thus ensuring that the water is fully purified and sterilized.

[0043] The filter assembly 61 includes a protective shell 611, an annular filter screen 612 fixedly connected to the inner side of the protective shell 611, a drain pipe 613 fixedly connected to the outer side of the annular filter screen 612, a flow-slowing component 614 rotatably connected to the inner side of the protective shell 611, an arc-shaped scraper 615 fixedly connected to the outer side of the flow-slowing component 614, an outer wall of the protective shell 611 fixedly connected to the top of the inner wall of the tank 1, an outer wall of the drain pipe 613 fixedly connected to the inner wall of the protective shell 611, an outer side of the arc-shaped scraper 615 slidably connected to the inner side of the protective shell 611, and a bottom of the flow-slowing component 614 fixedly connected to the output end of the drive motor 64. After water enters the filter assembly 61, the flow-slowing component 614 first disperses and slows the water flow, making it flow evenly to the annular filter screen 612. The annular filter screen 612 intercepts large particulate impurities in the water to achieve preliminary filtration. Then, the filtered water flows through the protective shell 611 into the adsorption assembly 62.

[0044] The flow-slowing component 614 includes a rotating shell 141, a hollow slide rod 142 slidably connected to the inner side of the rotating shell 141, a connecting pipe 144 slidably connected to the inner side of the hollow slide rod 142, an inlet shell 145 slidably connected to the top of the connecting pipe 144, a conical diverter block 143 fixedly connected to the top of the hollow slide rod 142, an annular plate 146 fixedly connected to the outer wall of the rotating shell 141, and a tension spring 147 fixedly connected to the inner side of the rotating shell 141. The bottom of the tension spring 147 is connected to the hollow slide rod 142. The bottom of rod 142 is fixedly connected, the outer side of rotating shell 141 is rotatably connected to the inner side of protective shell 611, the outer wall of rotating shell 141 is fixedly connected to the center of arc-shaped scraper 615, the inner side of conical diverter block 143 is slidably connected to the outer wall of connecting pipe 144, the outer wall of water inlet shell 145 is fixedly connected to the top of inner wall of tank 1, and drive motor 64 drives arc-shaped scraper 615 to rotate through rotating shell 141 in slow flow component 614. During the rotation process, arc-shaped scraper 615 scrapes... The impurities accumulated on its surface flow downwards along the gap between the annular filter screen 612 and the annular plate 146, eventually settling at the bottom of the protective shell 611. The impurities are discharged through the drain pipe 613, keeping the mesh of the annular filter screen 612 unobstructed, thus ensuring that the annular filter screen 612 continues to perform its filtering function and maintains good filtering efficiency. When the water flow from the inlet pipe 4 impacts the conical diverter block 143, the conical diverter block 143 drives the hollow slide rod 142 to slide into the rotating shell 141 under the impact of the water flow. At this time, the tension spring 147 is stretched, which can buffer the instantaneous large impact force brought by the water flow impact and prevent the impact force from being directly transmitted to other components and causing structural damage. At the same time, the conical diverter block 143 rotates together with the rotating shell 141 through the hollow slide rod 142. The conical diverter block 143 initially receives the impact of the water flow and uses its own arc-shaped protrusion to change the direction of the water flow, dispersing it and making it flow evenly to the annular filter screen 612.

[0045] The adsorption assembly 62 includes a support frame 621. A flow-blocking component 622 is fixedly connected to the top of the support frame 621, and a positioning component 624 is fixedly connected to the bottom of the support frame 621. An activated carbon cylinder 623 is movably installed at the bottom of the flow-blocking component 622. The bottom of the activated carbon cylinder 623 contacts the top of the positioning component 624, and the top of the flow-blocking component 622 is fixedly connected to the bottom of the protective shell 611. After water flows into the adsorption assembly 62, it first contacts the flow-blocking component 622, and then the water flows slowly through the interior of the activated carbon cylinder 623. Relying on the adsorption performance of the activated carbon in the activated carbon cylinder 623, residual chlorine, odors, and some organic pollutants in the water are removed, thereby achieving further purification of the water. The purified water is then discharged to the bottom of the tank 1 through the positioning component 624. In the adsorption assembly 62, each activated carbon cylinder 623 is installed relatively independently on the support frame 621, and each activated carbon cylinder 623 is positioned and constrained by the corresponding positioning component 624. When a specific activated carbon cartridge 623 needs to be replaced, the corresponding positioning component 624 is operated. For other activated carbon cartridges 623 that are not involved in the replacement operation, the corresponding positioning components 624, flow-blocking components 622, and other components in their respective branches remain in their original state, ensuring that water can flow normally through the corresponding activated carbon cartridge 623 for adsorption and purification. This achieves the effect that replacing one activated carbon cartridge 623 does not affect the normal operation of other adsorption components 62.

[0046] The positioning component 624 includes a fixing ring 401, an internally threaded ring 402 rotatably connected to the inner side of the fixing ring 401, a knob 403 fixedly connected to the bottom of the internally threaded ring 402, a guide tube 405 threadedly connected to the inner side of the internally threaded ring 402, a limiting plate 404 fixedly connected to the top of the guide tube 405, an outer side of the fixing ring 401 fixedly connected to the bottom of the support frame 621, an outer side of the limiting plate 404 slidably connected to the inner side of the support frame 621, and a top of the limiting plate 404 slidably connected to the inner side of the support frame 621. The bottom of the activated carbon cylinder 623 is in contact with the outside. When the activated carbon cylinder 623 needs to be replaced, first remove the bolts fixing the inspection door 3 on the tank body 1, and then rotate the knob 403 in the positioning component 624 so that the internal thread ring 402 rotates in the fixing ring 401. At this time, under the limiting action of the support frame 621, the guide pipe 405 drives the limiting plate 404 to slide downward, thereby increasing the distance between the limiting plate 404 and the flow blocking component 622, so as to facilitate the removal of the activated carbon cylinder 623.

[0047] The flow-blocking component 622 includes a sealing ring 201. A compression spring 202 is fixedly connected to the outer side of the sealing ring 201. A sliding cylinder 203 is fixedly connected to the bottom end of the compression spring 202. A connecting rod 204 is fixedly connected to the top of the sliding cylinder 203. A flow-blocking block 205 is fixedly connected to the top of the connecting rod 204. The outer side of the sealing ring 201 is fixedly connected to the top of the support frame 621. The outer side of the sliding cylinder 203 is slidably connected to the inner side of the sealing ring 201. The bottom of the flow-blocking block 205 is connected to the sealing ring 201. The top of the sliding cylinder 203 contacts the top of the activated carbon cylinder 623, and the bottom of the sliding cylinder 203 contacts the top of the activated carbon cylinder 623. During this process, the activated carbon cylinder 623 moves downward together with the limiting plate 404. During this process, the compression spring 202 gradually releases its elastic force, causing the sliding cylinder 203 to slide downward along the inner side of the sealing ring 201. This causes the connecting rod 204 to drive the flow blocking block 205 to slide downward. When the flow blocking block 205 contacts the sealing ring 201, it can block the flow of water, preventing water from continuing to flow into the area when replacing the activated carbon cylinder 623. This prevents water leakage and water flow interference from affecting the replacement operation, ensuring that the entire replacement process can be carried out safely and orderly. In the adsorption assembly 62, each activated carbon cylinder 623 is installed relatively independently on the support frame 621, and each activated carbon cylinder 623 is positioned and constrained by a corresponding positioning component 624. When a specific activated carbon cartridge 623 needs to be replaced, the corresponding positioning component 624 is operated. For other activated carbon cartridges 623 that are not involved in the replacement operation, the corresponding positioning components 624, flow-blocking components 622, and other components in their respective branches remain in their original state, ensuring that water can flow normally through the corresponding activated carbon cartridge 623 for adsorption and purification. This achieves the effect that replacing one activated carbon cartridge 623 does not affect the normal operation of other adsorption components 62.

[0048] Working principle: The water storage tank is composed of tank body 1, support legs 2, inspection door 3, water inlet pipe 4, drain pipe 5 and water treatment device 6. Its core water treatment process is mainly realized by water treatment device 6. The components inside water treatment device 6 work together to filter, adsorb and sterilize the water entering tank body 1 from water inlet pipe 4 in sequence. The finally treated water can be discharged through drain pipe 5 for use.

[0049] During use, water enters the tank through the inlet pipe 4 at the top of the tank 1, and then enters the filter component 61 in the water treatment device 6 for initial filtration to remove large particulate impurities. Next, it flows into the adsorption component 62, which removes residual chlorine, odors, and some organic pollutants from the water through adsorption. Subsequently, the water flows to the area below the partition plate 63 inside the tank 1. During this process, the drive motor 64 provides power for the operation of the filter component 61, while the ultraviolet germicidal lamp 65 sterilizes the water by emitting ultraviolet light to destroy the DNA structure of microorganisms. Finally, the electrode plate 7 generates strong oxidizing substances through electrolysis to further kill residual microorganisms in the water, thus ensuring that the water is fully purified and sterilized. The ultraviolet germicidal lamp 65 is model Aquafine17491LM, and the electrode plate 7 is model Jingyuanjia JYJ-ARC-02.

[0050] After water enters the filter assembly 61, it is first dispersed and slowed down by the flow slowing component 614, so that it flows evenly to the annular filter screen 612. The annular filter screen 612 intercepts large particles of impurities in the water to achieve preliminary filtration. Then, the filtered water flows through the protective shell 611 into the adsorption assembly 62.

[0051] During this process, the drive motor 64 drives the arc-shaped scraper 615 to rotate through the rotating shell 141 in the slow-flow component 614. As the arc-shaped scraper 615 rotates, it scrapes off the accumulated impurities on its surface, causing them to flow downwards along the gap between the annular filter screen 612 and the annular plate 146, and finally deposit at the bottom of the protective shell 611. The impurities are discharged through the drain pipe 613, keeping the mesh of the annular filter screen 612 unobstructed, thereby ensuring that the annular filter screen 612 continues to perform its filtering function and maintains good filtering efficiency.

[0052] When the water flowing out from the inlet pipe 4 impacts the conical diverter block 143, the conical diverter block 143 drives the hollow slide rod 142 to slide into the rotating shell 141 under the impact of the water flow. At this time, the tension spring 147 is stretched, which can buffer the large instantaneous impact force brought by the water flow and prevent the impact force from being directly transmitted to other components and causing structural damage. At the same time, the conical diverter block 143 rotates together with the rotating shell 141 through the hollow slide rod 142. The conical diverter block 143 initially receives the impact of the water flow and uses its own arc-shaped protrusion to change the direction of the water flow, so that it is dispersed and then flows evenly to the annular filter screen 612.

[0053] The relatively stable and gentle water flow environment created by the continuous rotation of the annular plate 146 can prevent the water flow from forming a rapid flow or generating a large vortex at the bottom of the protective shell 611 due to excessive impact force. This keeps the water flow at the bottom of the protective shell 611 relatively stable and slow, allowing impurities to settle steadily at the bottom and wait to be discharged through the drain pipe 613. This effectively ensures that impurities will not be stirred up again during the entire filtration process, maintaining the stable and efficient filtration operation of the filter assembly 61.

[0054] After the water flows into the adsorption component 62, it first comes into contact with the flow-blocking component 622. Then the water flows slowly through the interior of the activated carbon cylinder 623. Relying on the adsorption performance of the activated carbon in the activated carbon cylinder 623, residual chlorine, odor and some organic pollutants in the water are removed, thus achieving further purification of the water. The purified water is then discharged to the bottom of the tank 1 through the positioning component 624.

[0055] When it is necessary to replace the activated carbon cartridge 623, first remove the bolts that fix the inspection door 3 on the tank body 1, and then rotate the knob 403 in the positioning component 624 so that the internal thread ring 402 rotates in the fixing ring 401. At this time, under the limiting action of the support frame 621, the guide pipe 405 drives the limiting plate 404 to slide downward, thereby increasing the distance between the limiting plate 404 and the flow blocking component 622, so as to facilitate the removal of the activated carbon cartridge 623.

[0056] During this process, the activated carbon cylinder 623 moves downward along with the limiting plate 404. During this process, the compression spring 202 gradually releases its elastic force, causing the sliding cylinder 203 to slide downward along the inner side of the sealing ring 201. This causes the connecting rod 204 to drive the flow-blocking block 205 to slide downward. When the flow-blocking block 205 contacts the sealing ring 201, it can block the flow of water, preventing water from continuing to flow into this area when replacing the activated carbon cylinder 623. This prevents water leakage and water flow interference from affecting the replacement operation, ensuring that the entire replacement process can be carried out safely and orderly.

[0057] In the adsorption assembly 62, each activated carbon cartridge 623 is mounted relatively independently on the support frame 621, and each activated carbon cartridge 623 is positioned and constrained by a corresponding positioning component 624. When it is necessary to replace an activated carbon cartridge 623, the corresponding positioning component 624 can be operated. For other activated carbon cartridges 623 that are not involved in the replacement operation, the corresponding positioning components 624, flow-blocking components 622, and other components in their respective branches remain in their original state, ensuring that water can flow normally through the corresponding activated carbon cartridges 623 for adsorption and purification. This achieves the effect that replacing one activated carbon cartridge 623 does not affect the normal operation of other adsorption assemblies 62.

[0058] When it is necessary to clean the impurities deposited at the bottom of the protective shell 611, the activated carbon cartridge 623 can be removed first. At this time, the flow-blocking component 622 can block the flow of water. Then, the drain pipe 613 is opened, and water is injected into the connecting pipe 144 through the water inlet shell 145, so that the water flows into the rotating shell 141 and finally flows out from the bottom of the annular plate 146 along the rotating shell 141. At this time, the outflowing water can carry the impurities deposited at the bottom of the annular plate 146 out of the drain pipe 613, ensuring the cleanliness of the internal environment of the filter assembly 61 and helping to maintain the good filtration performance of the filter assembly 61.
