Description

Technical Field

[0001] This utility model relates to the field of filtration and separation technology, and in particular to a detachable multi-layer filter structure. Background Technology

[0002] Traditional filters are mostly one-piece structures. After prolonged use, a large amount of impurities accumulate on the filter surface, making cleaning difficult. If replacement is needed, the entire filter needs to be replaced, which not only increases operating costs but also wastes resources. Moreover, some filters have complex installation structures, requiring specialized tools for replacement, causing great inconvenience to users.

[0003] For example, a conveniently disassembled filter installation structure, as disclosed in CN220047469U, includes an outer frame and a filter body. The filter body has drive holes on both sides of its upper surface, and a rotating shaft is rotatably installed within each drive hole. Adjusting screws are fixedly connected to the upper and lower ends of each rotating shaft. Fixed threaded sleeves are threaded onto the outer walls of multiple adjusting screws. Fixed slots are provided on both sides of the inner walls of the upper and lower ends of the outer frame. Filter frames are provided on the inner walls of the filter body near the front and rear, with a primary filter and a secondary filter respectively housed within each filter frame. This invention, through its convenient disassembly and assembly design, allows for easier use and more efficient removal of the filter, reducing operational difficulty and cost. The multi-layered filter design achieves more efficient filtration, making it more convenient to use. However, this device uses multiple fixed threaded rods to fix the filter screens together, requiring the threaded rods to be removed sequentially during disassembly, which is somewhat inconvenient.

[0004] Therefore, it is necessary to design a detachable multi-layer filter structure that allows for easy installation and disassembly of the multi-layer filter, is simple to operate, and is convenient to use. Utility Model Content

[0005] To overcome the shortcomings of existing filter structures that use multiple threaded rods to fix the filter screens together, requiring the removal of each threaded rod during disassembly, which is inconvenient, this utility model provides a detachable multi-layer filter structure that allows for easy installation and disassembly of multi-layer filters, is simple to operate, and convenient to use.

[0006] The technical solution is as follows: A detachable multi-layer filter structure includes a base, a filter, a placement frame, a first mounting frame, a second mounting frame, a limiting frame, a sliding component, and a limiting component. Two placement frames are stacked on the upper part of the base. Filters are placed inside both the base and the placement frames. The first mounting frames are connected to both the left and right sides of the base, and the second mounting frames are connected to both the left and right sides of the placement frames. Limiting frames are slidably connected to the lower part of each second mounting frame. Each limiting frame engages with the first and second mounting frames adjacent to its lower side. A sliding component is provided on the right side of the placement frame for easy removal of the filter. Limiting components are provided on the left and right sides of the base for limiting and fixing.

[0007] Furthermore, the base has multiple support feet at the bottom.

[0008] Furthermore, both the first mounting frame and the second mounting frame are provided with L-shaped grooves at their front ends.

[0009] Furthermore, the sliding assembly includes a first guide rod, a push frame, and a first telescopic spring. The base and the right side of the placement frame are both connected to the first guide rod, and the push frame is slidably connected to each first guide rod. The first guide rod is connected to the adjacent push frame by a first telescopic spring.

[0010] Furthermore, it also includes a limiting assembly, which includes a lifting frame, a second telescopic spring, a guide rod, a pressing frame, and a third telescopic spring. The lifting frame is slidably connected inside both the first and second mounting frames. The limiting frame is in contact with its adjacent lifting frame. The first and second mounting frames are connected to their adjacent lifting frames by a second telescopic spring. The lower part of both the first and second mounting frames is connected to a second guide rod. The pressing frame is connected to the second guide rod. The pressing frame is in contact with its adjacent lifting frame. The pressing frame is connected to its adjacent second guide rod by a third telescopic spring.

[0011] Furthermore, all extrusion frames are wedge-shaped structures.

[0012] The beneficial effects are as follows: 1. This utility model moves the lifting frame downward to reset, and then rotates the limiting frame along the L-shaped groove, so that the limiting frame is freed from the restriction of the first and second mounting frames. Then the squeezing frame is released, the third telescopic spring returns to its original state, the squeezing frame squeezes the lifting frame to move upward, and then the base and the placement frame are separated, which achieves the effect of convenient installation and disassembly of multi-layer filter screens, simple operation and convenient use.

[0013] 2. This utility model allows for quick and easy replacement of the filter screen by moving the pusher, causing the first telescopic spring to retract and the pusher to move forward. After installation, the pusher is released, the first telescopic spring returns to its original position, and the pusher moves backward, positioning the filter screen within the placement frame and base.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] A detachable multi-layer filter structure, such as Figures 1-5 As shown, it includes a base 1, a filter screen 2, a placement frame 3, a first mounting frame 7, a second mounting frame 8, a limiting frame 9, a sliding component, and a limiting component. The base 1 has four support feet at the bottom for easy support and fixation. Two placement frames 3 are stacked on the top of the base 1. Filter screens 2 are placed inside both the base 1 and the placement frames 3. The first mounting frames 7 are connected to the left and right sides of the base 1, and the second mounting frames 8 are connected to the left and right sides of the placement frames 3. The front of the first mounting frames 7 and the second mounting frames 8 are provided with L-shaped grooves for easy fixation of the limiting frame 9. The lower part of the second mounting frame 8 is slidably connected to the limiting frame 9. The limiting frame 9 is engaged with the first mounting frame 7 and the second mounting frame 8 adjacent to its lower side. The right side of the placement frame 3 is provided with a sliding component, and the left and right sides of the base 1 are provided with limiting components.

[0022] like Figures 1-3 As shown, the sliding assembly includes a first guide rod 4, a push frame 5, and a first telescopic spring 6. The base 1 and the right side of the placement frame 3 are both connected to the first guide rod 4. The push frame 5 is slidably connected to the first guide rod 4. The first guide rod 4 is connected to the adjacent push frame 5 by the first telescopic spring 6.

[0023] like Figure 4 and Figure 5 As shown, it also includes a limiting assembly, which includes a lifting frame 10, a second telescopic spring 11, a guide rod, a pressing frame 13, and a third telescopic spring 14. The lifting frame 10 is slidably connected inside the first mounting frame 7 and the second mounting frame 8. The limiting frame 9 is in contact with its adjacent lifting frame 10. The second telescopic spring 11 is connected between the first mounting frame 7 and the second mounting frame 8 and their adjacent lifting frame 10. The lower part of the first mounting frame 7 and the second mounting frame 8 is connected to the second guide rod 12. The pressing frame 13 is connected to the second guide rod 12. The pressing frame 13 is a wedge-shaped structure. The pressing frame 13 is in contact with its adjacent lifting frame 10. The third telescopic spring 14 is connected between the pressing frame 13 and its adjacent second guide rod 12.

[0024] At this time, the second telescopic spring 11 is in the retracted state. When using this device, first place the base 1 in the filter screen 2 installation area, and then insert the filter screen 2 into the base 1 and the placement frame 3 for installation. When multiple layers of the filter screen 2 need to be spliced, first move the extrusion frame 13 outward along the second guide rod 12. The third telescopic spring 14 is compressed and retracted, and the second telescopic spring 11 returns to its original position, causing the lifting frame 10 to move downward. Insert the limiting frame 9 along the L-shaped groove into the first installation frame 7 and the second installation frame 8 to be spliced, then rotate the limiting frame 9, and then release the extrusion frame 13. The third telescopic spring 14 returns to its original position, driving the extrusion frame 13 to move and extruding the lifting frame 10, causing the lifting frame 10 to move upward. The second telescopic spring 11 retracts, causing the limiting frame 9 to engage with its adjacent first mounting frame 7 and second mounting frame 8, thus completing the installation. Similarly, when disassembly is required, the squeezing frame 13 is pushed outward, causing the lifting frame 10 to move downward and reset via the second telescopic spring 11. Then, the limiting frame 9 is rotated along the L-shaped groove, causing it to disengage from the first mounting frame 7 and second mounting frame 8. The squeezing frame 13 is then released, and the third telescopic spring 14 returns to its original position, causing the squeezing frame 13 to move and the lifting frame 10 to move upward. The base 1 and the placement frame 3 are then separated, completing the disassembly. This allows for convenient installation and disassembly of the multi-layer filter screen 2, making the operation simple and convenient.

[0025] When the filter screen 2 needs to be disassembled, push the pusher 5 forward along the first guide rod 4 to retract the first telescopic spring 6. The pusher 5 moves forward and pushes the filter screen 2 out, allowing the filter screen 2 to be removed for replacement. Then, insert the filter screen 2 into the base 1 and the placement frame 3. After installation, release the pusher 5, and the first telescopic spring 6 returns to its original position, causing the pusher 5 to move backward so that the filter screen 2 is located in the placement frame 3 and the base 1. This allows for quick disassembly and replacement of the filter screen 2, making it convenient to use.
