Description

Technical Field

[0001] This utility model relates to the field of aquarium filtration technology, specifically a liftable filter paper filter with a quick-release structure. Background Technology

[0002] In modern life, people enjoy keeping ornamental fish in aquariums at home during their leisure time to add to their enjoyment of life. However, after long-term use, impurities will accumulate in the water of the aquarium, affecting the viewing effect and the health of the fish. As a result, aquarium filter cloth filters with filter cloth as the filtration medium have appeared on the market to remove suspended particles and pollutants from the water.

[0003] For example, Chinese utility model patent CN221931051U relates to the field of aquarium filtration equipment technology, specifically a novel aquarium filter cloth filter, including a filter frame. The top of the filter frame is equipped with a motor-driven winding and unwinding assembly, and the bottom of the filter frame is equipped with a filter cavity composed of a filter plate assembly. The filter cavity is equipped with two sets of filter cloth guide shafts and a sensor. Water baffles are fixed on the front and rear sides of the filter plate assembly, and there is a gap between the water baffles and the corresponding outer surfaces of the filter plate assembly to form a guide groove. The winding and unwinding assembly includes a winding shaft and an unwinding shaft, and the unwinding shaft is slidably disposed on the top of the filter frame. In this utility model, the filter plate assembly and the winding and unwinding assembly are integrated into one structure, which reduces the space occupied for installation and storage. The unwinding shaft is disposed on the filter cloth frame through a sliding groove, and the unwinding shaft is pushed to slide along the sliding groove during the winding process of the winding shaft, thereby avoiding the squeezing interference of the unwinding shaft on the winding shaft when winding the filter cloth. At the same time, its overall structure is smaller.

[0004] However, some problems still exist. The device has certain shortcomings in practical use. Although its structure is relatively compact and can effectively avoid interference between winding and unwinding, when the filter paper needs to be replaced, the entire filter must be removed from the aquarium. Furthermore, when placing the filter paper, it needs to be manually pulled around once, which is cumbersome and affects user convenience. Therefore, a lifting filter paper filter with a quick-release structure is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1 to 5 and Figures 8 to 9 This embodiment of a lifting filter paper filter with a quick-release structure includes a housing 1. A central partition plate 2 is fixed between the left and right side walls of the housing 1. A flow guide box 3, which is fixed to the housing 1, is fixed to the front of the central partition plate 2. Filter media buckets 6 are fixed to both the left and right sides of the flow guide box 3. The housing 1, the central partition plate 2, the flow guide box 3, and the filter media buckets 6 are all sealed together. The filter media bucket 6 includes a sieve bucket 602, a filter media tube 603, and two flow guide blocks 601. Both flow guide blocks 601 are connected to the housing 1. The flow guide box 3 is fixed, and a flow guide groove 5 is provided at the bottom of the flow guide box 3. A filter groove 4 communicating with the groove opening is provided at the top of the flow guide box 3. The top flow guide block 601 is connected to the filter groove 4. Sewage enters the interior of the filter groove 4 after passing through the inlet 22. Under the push of the water flow, the filter paper 16 will adhere to the filter groove 4, so that the sewage passes through the filter paper 16 and completes the filtration. The flow guide box 3 is provided with an interlayer for collecting the filtered water. The filter groove 4, the top flow guide block 601 and the interlayer are connected.

[0035] The bottom guide block 601 is connected to the guide channel 5. The two guide blocks 601 are fixed to the filter media tube 603. The filter media tube 603 contains filter media. When sewage passes through the filter media tube 603, it can perform biological filtration. The filter media tube 603 is a transparent tube, so the internal filtration can be observed. The bottom guide block 601 is fixed to the screen barrel 602 located inside the filter media tube 603. The screen barrel 602 can prevent the filter media from moving to the outside of the filter media tube 603. The back of the middle partition plate 2 is fixed with a motor fixing plate 7 that is fixed to the box 1. A stepper motor 8 is fixed at the bottom of the motor fixing plate 7. A lifting mechanism 9 is provided on the motor fixing plate 7.

[0036] Two slide rail fixing plates 10 are fixed between the central partition plate 2 and the box body 1. A paper roll slide rail 11 is fixed to the top of the slide rail fixing plate 10, and a paper roll box 12 is fixed to the top of the paper roll slide rail 11. The slide rail fixing plate 10 and the paper roll box 12 are fixed together by the paper roll slide rail 11, so that the paper roll box 12 can slide on the top of the slide rail fixing plate 10. The two paper roll boxes 12 are made of the same shape to improve mold utilization and reduce mold opening cost. A roller 17 that fits against the paper roll box 12 is fixed to the top of the slide rail fixing plate 10. When the paper box 12 slides, the roller 17 makes the paper roll box 12 slide more stably. The front of the two paper roll boxes 12 is fixed with a connecting cover 13, and the front of the connecting cover 13 is fixed with a handle 14. By pulling the handle 14, the connecting cover 13 can be moved together with the two paper roll boxes 12. When the filter paper 16 is placed, the new filter paper 16 on the right side can be placed directly inside the paper roll box 12 without the quick release assembly 15. When the new filter paper 16 is rotated, the new filter paper 16 will rotate clockwise, so that the new filter paper 16 rolls away from the guide box 3.

[0037] The toilet paper roll cassette 12 is equipped with a quick-release assembly 15, which includes a spring plate 1501 fixed to the toilet paper roll cassette 12. A toilet paper roll fixing head 1502 is inserted inside the spring plate 1501. The spring plate 1501 has a certain elasticity, and when the toilet paper roll fixing head 1502 is pulled forcefully, the toilet paper roll fixing head 1502 can be disconnected from the spring plate 1501. A roll 1503 is inserted into the outer surface of the toilet paper roll fixing head 1502. A toilet paper roll drive head 1504 is inserted into the inside of the roll 1503. The back of the toilet paper roll drive head 1504 is provided with an inclined surface. A motor adapter fixed to the output shaft of the stepper motor 8 is inserted into the back of the left side of the toilet paper roll drive head 1504. When the stepper motor 8 is started, the motor adapter 1505 can drive the paper roll drive head 1504 and the roll 1503 to rotate. The paper roll drive head 1504 is connected to the motor adapter 1505, so that the paper roll drive head 1504 and the motor adapter 1505 can be quickly disconnected. The back of the paper roll drive head 1504 is provided with an inclined surface. When the paper roll drive head 1504 and the motor adapter 1505 are not aligned, the motor adapter 1505 will contact and squeeze the inclined surface, thereby pushing the paper roll drive head 1504 to rotate until it is aligned. The outer surface of the quick-release assembly 15 is wrapped with filter paper 16, which is used to filter sewage.

[0038] The interior of the housing 1 is equipped with a liquid level sensor 18. The height of the liquid level sensor 18 is lower than the height of the diversion box 3. The liquid level sensor 18 is used to detect the liquid level. When the water level reaches the designated position, it transmits an electrical signal. The top of the middle isolation plate 2 is fixed with a top cover 19 that is fixed to the housing 1. The right side of the diversion box 3 is connected to a through-plate elbow 20 that extends to the back of the middle isolation plate 2. The back of the housing 1 is fixed with a drain outlet 21 and a water inlet 22. The drain outlet 21 is connected to the through-plate elbow 20. Vertical sliders 23 are fixed on opposite sides of the left and right side walls of the housing 1. The top of the two vertical sliders 23 is fixed with a lifting cover 24. When the lifting cover 24 is pushed and moved by the lifting mechanism 9, the vertical sliders 23 can ensure the stability of the movement of the lifting cover 24.

[0039] Please see Figures 6 to 7 In this embodiment, the lifting mechanism 9 includes two adjustment components fixed to the motor fixing plate 7. Each adjustment component includes an adjustment seat 901 fixed to the motor fixing plate 7. An adjustment spring is provided inside the adjustment seat 901. An adjustment block 902 is provided on the top of the adjustment spring, which is slidably connected to the adjustment seat 901 and fixed to the dual-axis motor 903. When the synchronous belt 905 is used for a long time and becomes loose due to tension, the elasticity of the adjustment spring will push the adjustment block 902 and the dual-axis motor 903 to move upward, thereby keeping the synchronous belt 905 taut.

[0040] A dual-axis motor 903 is fixed between the two adjustment components. The stepper motor 8, liquid level sensor 18, and dual-axis motor 903 mentioned in the text are all electrically connected to the controller and power supply. The controller is used to synchronously control the start, stop, and direction of the stepper motor 8 and the dual-axis motor 903 to realize the lifting, winding, and replacement operations of the filter paper 16. The encoder of the stepper motor 8 can control the number of rotations and record the distance moved, thereby recording the remaining meters of the filter paper 16. The controller is not shown in the figure. Both output shafts of the dual-axis motor 903 are fixed with transmission components. The transmission components include a first synchronous pulley 904, a synchronous belt 905, and a second synchronous pulley 906. The first synchronous pulley 904 is fixed to the output shaft of the dual-axis motor 903, and the second synchronous pulley 906 is fixed to the synchronous shaft 907. The first synchronous pulley 904 and the second synchronous pulley 906 are connected to the synchronous belt 905 for transmission. When the dual-axis motor 903 starts, it will cause the first synchronous pulley 904 and the second synchronous pulley 906 to rotate and the synchronous belt 905 to move.

[0041] The two transmission components have a synchronous shaft 907 fixed inside. The outer surface of the synchronous shaft 907 is rotatably connected to two shaft support seats 908. The bottom of the shaft support seat 908 is fixed to a lifting rod base plate 909. The lifting rod base plate 909 has a positioning block 910 that is fixed to the housing 1 inserted inside. The lifting rod base plate 909 is not directly fixed to the housing 1, but is positioned by the positioning block 910. This allows the lifting mechanism 9 and the motor mounting plate 7 to be easily and quickly removed after the motor mounting plate 7 is removed, thus facilitating equipment maintenance.

[0042] A lifting rod 912 is inserted between the lifting rod base plate 909 and the motor mounting plate 7. The lifting rod 912 makes the movement of the guide assembly more stable. The outer surface of the lifting rod 912 is slidably connected to a guide assembly fixed to the transmission assembly. The guide assembly includes a lifting slider 911 fixed to two synchronous belts 905. Inside the lifting slider 911, a paper roll guide rod 913 is fixed, which penetrates into the flow box 3 and is attached to the filter paper 16. A positioning groove 916 is opened on the top of the lifting slider 911. The internal sliding connection of 6 is a positioning rod 917 fixed to the paper roll guide rod 913. The positioning groove 916 is specifically an "L" shaped groove. After the positioning rod 917 moves into the positioning groove 916, the paper roll guide rod 913 needs to drive the positioning rod 917 to move to the left and then forward to remove it. When the filter paper 16 moves, it will cause the paper roll guide rod 913 to move to the right, so that the positioning rod 917 will not easily move out of the positioning groove 916, thus making the paper roll guide rod 913 easy and quick to install and remove.

[0043] A push rod 914 is fixed to the top of the paper roll guide rod 913. The push rod 914 is used to move the lifting cover 24. The push rod 914 is located at one-quarter of the length of the paper roll guide rod 913 and can contact the center of gravity of the lifting cover 24. A stabilizing block 915 is fixed to the top of the lifting rod base plate 909. The front of the middle partition plate 2 has a slot that matches the paper roll guide rod 913. The bottom semicircle of the slot is concentric with the stabilizing block 915. When the paper roll guide rod 913 moves to the bottom, the bottom of the paper roll guide rod 913 is concentric with the stabilizing block 915. The guide rod 913 will contact the groove and the stabilizing block 915. When the paper roll guide rod 913 generates upward force due to the movement of the filter paper 16, the stabilizing block 915 can restrict the downward movement of the other side of the paper roll guide rod 913, thereby ensuring the stability of the paper roll guide rod 913. The bottom wall of the guide groove 5 is fixed with a second magnet 26, and the bottom of the paper roll guide rod 913 is fixed with a first magnet 25. The second magnet 26 and the first magnet 25 are not in contact, but there is a certain attraction between them, which can also prevent the paper roll guide rod 913 from tilting.

[0044] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0045] The working principle of the above embodiments is as follows:

[0046] (1) When filtering sewage, the sewage flows through the inlet 22 into the filter tank 4 of the guide box 3. After being filtered by the filter paper 16, the filtered water gathers in the guide box 3 and flows through the top guide block 601 into the filter material tube 603 for biochemical filtration. Then, it flows back into the guide channel 5 of the guide box 3 through the screen 602 and the bottom guide block 601, and is discharged through the plate elbow 20 and the drain outlet 21. When the filter paper 16 is saturated, the water level rises. After contacting the liquid level sensor 18, the liquid level sensor 18 transmits a signal to start the stepper motor 8, which can make the motor adapter 1505, the paper roll drive head 1504 and the roll 1503 on the left rotate synchronously, thereby winding the filter paper 16, moving the filter paper 16, and winding the saturated part onto the roll 1503, thereby replacing the filter paper 16 inside the guide box 3 with a new part, and continuing to filter.

[0047] (2) When it is necessary to disassemble the filter paper 16, start the dual-axis motor 903 and the stepper motor 8. The dual-axis motor 903 drives the first synchronous pulley 904, the second synchronous pulley 906 and the synchronous shaft 907 to rotate, and the synchronous belt 905 drives the lifting slider 911, the paper roll guide rod 913 and the push rod 914 to move upward synchronously. At the same time, the stepper motor 8 drives the motor adapter 1505, the paper roll transmission head 1504 and the roll 1503 to rotate, and wind up the remaining filter paper 16. Since the filter paper 16 is attached to the bottom of the paper roll guide rod 913, the filter paper 16 rises together with the paper roll guide rod 913 and gradually leaves the guide rod. Inside the flow box 3, as the paper roll guide rod 913 and the push rod 914 continue to rise, the push rod 914 will contact the lifting cover 24 and push the lifting cover 24 to move upward together, thereby exposing the upper part of the filter paper 16. After the paper roll guide rod 913 completes its upward movement, by pulling the handle 14, the connecting cover 13, the two paper roll boxes 12, the quick release assembly 15 and the filter paper 16 can be moved out of the equipment as a whole. Finally, by pulling the quick release assembly 15 upward, the filter paper 16 and the quick release assembly 15 can be taken out together, completing the disassembly operation. This structure significantly improves the convenience of operation and maintenance efficiency, while enhancing the practicality of the equipment.

[0048] (3) When reinstalling the filter paper 16, firstly, attach one end of the new filter paper 16 to the roll 1503. Then, place the roll fixing head 1502 above the spring plate 1501 and apply pressure to make it move down. The spring plate 1501 undergoes elastic deformation. After the roll fixing head 1502 is fully inserted into the spring plate 1501, the spring plate 1501 returns to its original state and limits the roll fixing head 1502. At this time, place the new filter paper 16 in the roll box 12 on the right side and push the roll box 12 forward to drive the quick-release assembly 15 and the filter paper 16 to move into the equipment. After the movement is in place, the roll transmission head 1504 and the motor adapter 1505 are connected. Finally, start the dual-axis motor 903 and the stepper motor 8 in reverse to send the new filter paper 16 into the predetermined position inside the guide box 3. This installation structure significantly improves the efficiency of replacing the filter paper 16, and the operation is simple and reliable, effectively improving the practicality and maintenance convenience of the equipment.
