Description

Technical Field

[0001] This utility model relates to the field of filtration technology for purified water units, and more specifically, it relates to an activated carbon filter for purified water units. Background Technology

[0002] In existing technologies, activated carbon filters for purified water units face a number of challenges, mainly in terms of structural design, ease of operation, and long-term stability.

[0003] First, existing activated carbon filters typically use a static filtration method. While this method is simple, it easily leads to the accumulation and caking of activated carbon particles during use. Due to the lack of sufficient dynamic flow of water within the filter, the gaps between the activated carbon particles are gradually filled with impurities, causing internal blockage. This blockage not only reduces the water flow rate but also severely affects the filtration efficiency, preventing the filter from fully performing its function of removing impurities and improving water quality. This inefficient filtration has an adverse impact on the overall efficiency of the water treatment process and increases maintenance and operating costs.

[0004] Secondly, in terms of installation and disassembly, existing activated carbon filters are usually designed to be complex and not user-friendly. After long-term use, activated carbon needs to be replaced regularly to ensure filtration effect. However, the complex structural design makes the replacement process time-consuming and cumbersome, requiring operators to spend a lot of time and energy on maintenance, increasing equipment downtime and maintenance costs. This inconvenience not only affects the efficiency of the filter but may also affect the operation of the entire water treatment system.

[0005] Furthermore, while some equipment incorporates devices for quick replacement and maintenance, these devices are often simple in structure and lack sufficient mechanical strength and stability. During use, the impact of water flow or vibrations during equipment operation can cause the fixing structure to loosen or even detach. This not only affects the fixation effect of the activated carbon filter but may also cause the filter to shift or be damaged during operation, further impacting its filtration performance and service life. This stability issue poses a threat to the reliable operation of the equipment and increases operational risks. Utility Model Content

[0032] Please see Figures 1-6An activated carbon filter for a purified water unit includes a treatment chamber 1, in which a filtration device is installed. A quick-locking device is installed on the treatment chamber 1. The quick-locking device includes a sleeve 2, a mating plate 3, a mating block 4, an unlocking sleeve 5, a clearance groove 6, a locking rod 7, a locking slot 8, a locking block 9, and a tension spring 10. The sleeve 2 is detachably fitted onto the outside of the locking rod 7. The mating plate 3 is fixedly connected to one side of the locking block 9. The mating block 4 is fixedly installed inside the unlocking sleeve 5. The unlocking sleeve 5 is rotatably fitted onto the outside of the sleeve 2. The clearance groove 6 is located inside the sleeve 2. The locking slot 8 is located outside the locking rod 7. The locking block 9 engages in the locking slot 8. The mating plate 3 is connected to the outer wall of the sleeve 2 via the tension spring 10. A self-locking mechanism is provided on the outer side of sleeve 2. The self-locking mechanism includes a return sleeve 11, a locking sleeve 12, a push rod 13, a connecting block 14, a return spring 15, a through hole 16, a return block 17, a lock groove 18, a locking rod 19, and a connecting spring 20. The return sleeve 11 is rotatably sleeved on the outer side of sleeve 2, the locking sleeve 12 is slidably sleeved on the outer side of sleeve 2, the push rod 13 is fixedly connected to one side of the locking sleeve 12, the connecting block 14 is fixedly connected to the outer side of sleeve 2, the two ends of the return spring 15 are respectively connected to the connecting block 14 and the return block 17, multiple lock grooves 18 are opened on the outer side of sleeve 2, one end of the locking rod 19 is connected to the outer wall of the unlocking sleeve 5 through the connecting spring 20, and the other end of the locking rod 19 is inserted into the lock groove 18.

[0033] The outer side of the card sleeve 2 is provided with a sliding groove 21, and the inner side of the lock sleeve 12 is fixed with a slider 22. The sliding groove 21 and the slider 22 are adapted to each other.

[0034] A push spring 23 is movably sleeved on the outer side of the push rod 13. One end of the push spring 23 is connected to the lock sleeve 12, and the other end of the push spring 23 is in contact with the return sleeve 11.

[0035] Anti-slip strips 24 are fixedly provided on the outer sides of both the lock sleeve 12 and the return sleeve 11.

[0036] In this embodiment, when the filter 26 needs maintenance or replacement, firstly, the return sleeve 11 is rotated, causing the return sleeve 11 to move the through hole 16. Simultaneously, the return sleeve 11 moves the return block 17 connected to one side. Then, the return block 17 cooperates with the connecting block 14 to compress the return spring 15. When the return spring 15 is compressed to its limit, the through hole 16 moves to the position corresponding to the top rod 13. Then, the locking sleeve 12 is pushed, causing the locking sleeve 12 to move the inner slider 22 along the slide groove 21. The locking sleeve 12 also causes the top rod 13 to slide through the through hole 16. Then, the locking sleeve 12 cooperates with the return sleeve 11 to compress the push spring 23 sleeved on the outside of the top rod 13. When the push spring 23 is compressed to its limit, the outer side of the locking rod 19 loses the restraint of the locking sleeve 12. Then, rotate the unlocking sleeve 5. The unlocking sleeve 5 will move the locking rod 19 that is slidably set on the side wall. Then, the side wall of the lock groove 18 will press against one end of the locking rod 19. Due to the rounded corners at the edge of the lock groove 18 and the end of the locking rod 19, one end of the locking rod 19 will slide out of the lock groove 18, and the other end of the locking rod 19 will cause the connecting spring 20 to stretch. At the same time, the unlocking sleeve 5 will cause the mating block 4 to rotate. Then, the mating block 4 will push the mating plate 3 to move. Then, the mating plate 3 will cause the tension spring 10 connected on one side to stretch. At the same time, the mating plate 3 will cause the locking block 9 set on one side to slide out of the locking groove 8, so that the locking block 9 enters the storage groove. Then, pull the locking sleeve 2 upward and pull the locking rod 7 downward to remove the locking sleeve 2 and the locking rod 7. Then, remove the mounting frame 25 and then... Filter 26 can be removed for maintenance and replacement. After maintenance and replacement of filter 26, filter 26 is reinstalled inside the treatment chamber 1. Then, the mounting frame 25 is reinstalled on top of the treatment chamber 1, so that the mounting frame 25 and the treatment chamber 1 cooperate to press filter 26 tightly. At the same time, the reserved holes on the mounting frame 25, the treatment chamber 1, and filter 26 are aligned. Then, the locking rod 7 is passed through the reserved hole, and the unlocking sleeve 5 is rotated in the opposite direction. The unlocking sleeve 5 will drive the mating block 4 to rotate and reset. Then, the mating plate 3 loses the limit of the mating block 4. Then, the tension spring 10 drives the mating plate 3 to reset, so that the mating plate 3 drives the locking block 9 to reset. Then, the locking sleeve 2 is re-fitted onto the outside of the locking rod 7. Due to the chamfered structure design at one end of the locking rod 7 and the chamfer on one side of the locking block 9, The design involves the locking lever 7 pushing the locking block 9 open, allowing it to re-enter the storage slot. Simultaneously, the locking block 9, through the mating plate 3, causes the tension spring 10 to stretch again. Once the locking sleeve 2 is fully engaged with the outside of the locking lever 7, the tension spring 10 causes the unlocking plate and locking block 9 to reset, allowing the locking block 9 to re-insert into the slot 8. Then, the locking sleeve 12 is released, and the push spring 23 pushes the locking sleeve 12 to reset. The locking sleeve 12 then causes the push rod 13 and the slider 22 to slide and reset along the slide groove 21. When the push spring 23 is fully reset, the through hole 16 loses the limit of the push rod 13. Then, the return spring 15 causes the return block 17 to reset, and the return block 17 causes the return sleeve 11 to rotate and reset. Finally, the return sleeve 11 causes the through hole 16 to reset and move to a position not corresponding to the push rod 13.Then, the top rod 13 locks the sleeve 12 to form a stable limit, preventing the sleeve 12 from moving. The inner wall of the sleeve 12 then further limits the outer end of the locking rod 19, preventing it from moving. Finally, the locking rod 19 and the locking groove 18 cooperate to stably limit the unlocking sleeve 5, preventing it from rotating and thus preventing accidental unlocking caused by rotation. Due to the structural design of the inner wall of the groove 8 and one side of the block 9, the stability of the fixing structure is ensured, achieving stable fixation of the filter 26.

[0037] Please see Figures 1-4 As one embodiment of the filtration device: the filtration device includes a mounting frame 25, a filter 26 and a turbine assembly 27. The mounting frame 25 is detachably mounted above the treatment chamber 1. The filter 26 is detachably mounted inside the treatment chamber 1, and the edges of the filter 26 are pressed together by the mounting frame 25 and the treatment chamber 1. The turbine assembly 27 is mounted in the mounting frame 25, and the filter 26 is an activated carbon filter.

[0038] An input chamber 28 is detachably mounted on the top of the mounting frame 25, and a filter plate 29 is detachably mounted on the top of the input chamber 28.

[0039] A rotating frame 30 is connected to one side of the turbine assembly 27, and the rotating frame 30 is movably disposed in the filter 26.

[0040] The bottom of the processing chamber 1 is detachably equipped with a support frame 31, which is in contact with the filter 26.

[0041] More specifically, when the equipment is needed, the water source to be treated is first delivered to one side of the filter plate 29 through the external input device, so that the filter plate 29 blocks large-volume filter objects on one side. Then the water source enters the input chamber 28 and then enters the filter 26 set in the treatment chamber 1. Then the turbine assembly 27 set inside the mounting frame 25 is opened. The operation of the turbine assembly 27 will accelerate the input speed. At the same time, the turbine assembly 27 will drive the rotating frame 30 set on one side to rotate, so that the rotating frame 30 drives the water source to rotate, forming a vortex, making the water flow turbulent. Then, under this condition, the impurities accumulated or deposited on the inner wall or bottom of the filter 26 will be carried by the water to flow, so that the filter 26 will not be blocked due to long-term accumulation, thus affecting the filtration effect. In addition, the rotation of the water makes the water contact the inner wall of the filter 26 more fully, resulting in a better filtration effect. Then the filtered water enters the space between the outer wall of the filter 26 and the treatment chamber 1, and then flows into the equipment corresponding to the next external process.

[0042] In summary, during the use or operation of the overall equipment: when maintenance or replacement of filter 26 is required, first rotate the return sleeve 11, causing the return sleeve 11 to move the through hole 16. Simultaneously, the return sleeve 11 will move the return block 17 connected to one side. Then, the return block 17 will cooperate with the connecting block 14 to compress the return spring 15. When the return spring 15 is compressed to its limit, the through hole 16 moves to the position corresponding to the push rod 13. Then, push the locking sleeve 12, causing the locking sleeve 12 to move the inner slider 22 along the slide groove 21. The locking sleeve 12 will also cause the push rod 13 to slide through the through hole 16. Then, the locking sleeve 12 will cooperate with the return sleeve 11 to compress the push spring 23 sleeved on the outside of the push rod 13. When the push spring 23 is compressed to its limit, the locking sleeve 12 will release the pressure. When the outer side of the lever 19 is no longer limited by the locking sleeve 12, and then the unlocking sleeve 5 is rotated, the unlocking sleeve 5 will drive the locking lever 19, which is slidably set on the side wall, to move. Then the side wall of the locking groove 18 will press against one end of the locking lever 19. Due to the rounded corners at the edge of the locking groove 18 and the end of the locking lever 19, one end of the locking lever 19 will slide out of the locking groove 18, and the other end of the locking lever 19 will drive the connecting spring 20 to stretch. At the same time, the unlocking sleeve 5 will drive the mating block 4 to rotate, and then the mating block 4 will push the mating plate 3 to move. Then the mating plate 3 will drive the tension spring 10 connected on one side to stretch. At the same time, the mating plate 3 will drive the locking block 9 set on one side to slide out of the locking groove 8, so that the locking block 9 enters the storage groove. Then the locking sleeve 2 is pulled upward and the locking lever 7 is pulled downward, so that the locking sleeve 2 can be released. Remove the locking rod 7, then remove the mounting frame 25, and then remove the filter 26 for maintenance and replacement. After the filter 26 is maintained and replaced, reinstall the filter 26 inside the treatment chamber 1, and then reinstall the mounting frame 25 on top of the treatment chamber 1, ensuring that the mounting frame 25 and the treatment chamber 1 cooperate to press the filter 26 tightly. At the same time, align the reserved holes on the mounting frame 25, the treatment chamber 1, and the filter 26. Then, pass the locking rod 7 through the reserved hole, and then rotate the unlocking sleeve 5 in the opposite direction. The unlocking sleeve 5 will then drive the mating block 4 to rotate and reset. Then, the mating plate 3 will lose the limit of the mating block 4, and then the tension spring 10 will drive the mating plate 3 to reset, causing the mating plate 3 to drive the locking block 9 to reset. Finally, the locking sleeve 2 is re-fitted onto the locking rod 7. On the outside, due to the chamfered structure design at one end of the locking lever 7 and the chamfered design on one side of the locking block 9, the locking lever 7 will push the locking block 9 open, allowing the locking block 9 to re-enter the storage slot. At the same time, the locking block 9 will be stretched again by the tension spring 10 driven by the mating plate 3. When the locking sleeve 2 is fully fitted onto the outside of the locking lever 7, the tension spring 10 will drive the unlocking plate and the locking block 9 to reset, allowing the locking block 9 to be reinserted into the locking slot 8. Then, the locking sleeve 12 will be released, and the push spring 23 will push the locking sleeve 12 to reset. Then, the locking sleeve 12 will drive the top rod 13 and the slider 22 to slide and reset along the slide groove 21. When the push spring 23 is fully reset, the through hole 16 will lose the limit of the top rod 13. Then, the return spring 15 will drive the return block 17 to reset. Then, the return block 17 will drive the return sleeve 11 to rotate and reset.Then, the return sleeve 11 will drive the through hole 16 to reset and move to a position not corresponding to the top rod 13. The top rod 13 will then lock the sleeve 12 to form a stable limit, preventing the sleeve 12 from moving. The inner wall of the sleeve 12 will then further limit the outer end of the locking rod 19, preventing it from moving. The locking rod 19 and the locking groove 18 will then cooperate to stably limit the unlocking sleeve 5, preventing it from rotating. This prevents accidental unlocking caused by the rotation of the unlocking sleeve 5. Due to the structural design of the inner wall of the groove 8 and one side of the block 9, the stability of the fixing structure is ensured, achieving stable fixing of the filter 26.

[0043] When the equipment is needed, the water to be treated is first delivered to one side of the filter plate 29 through the external input device. The filter plate 29 then blocks large-volume filter objects on one side. The water then enters the input chamber 28 and then the filter 26 set in the treatment chamber 1. The turbine assembly 27 set inside the mounting frame 25 is then opened. The operation of the turbine assembly 27 will accelerate the input speed. At the same time, the turbine assembly 27 will drive the rotating frame 30 set on one side to rotate, causing the rotating frame 30 to rotate the water and form a vortex, making the water flow turbulent. Then, under this condition, the impurities accumulated or deposited on the inner wall or bottom of the filter 26 will be carried away by the water and flow, so that the filter 26 will not be blocked due to long-term accumulation and affect the filtration effect. In addition, the rotation of the water makes the water more fully contact the inner wall of the filter 26, resulting in a better filtration effect. Then, the filtered water enters the space between the outer wall of the filter 26 and the treatment chamber 1, and then flows into the equipment corresponding to the next external process.

For all the fixed connections mentioned above, welding is preferred.
