Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to anti-clogging filters. Background Technology

[0002] When washing dishes, food scraps, vegetable scraps, and thick, sticky grease on plates and bowls are washed towards the drain with the water. This is where the kitchen anti-clogging filter plays a crucial role. The fine mesh can accurately intercept food scraps, from large chunks of meat to small grains of rice, none of which can pass through. The scraps that would normally mix with grease and accumulate on the inner wall of the pipe are successfully blocked, and without the help of scraps, grease is also difficult to adhere to the pipe wall for a long time.

[0003] Some existing anti-clogging filters use a multi-layered filtration structure to block debris. During use, wastewater from washing vegetables, dishes, etc., flows in through the inlet. First, a coarse filter intercepts large particles like vegetable leaves and rice grains. Then, the wastewater flows through a fine filter for further filtration of smaller impurities. Some filters also have magnetic adsorption devices to attract metal debris from the water.

[0004] However, in actual use, solid impurities such as food scraps and oil stains cannot be effectively separated and intercepted, and will directly enter the pipes. Over time, these impurities will gradually accumulate on the inner wall of the pipes, making the inner diameter of the pipes smaller, slowing down the water flow, and eventually causing the pipes to become blocked. Once a blockage occurs, it will not only affect normal drainage, but also cause sewage backflow and pollute the kitchen environment. In response to the above problems, an anti-clogging filter is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-clogging filter, which aims to improve the problem that some existing anti-clogging filters cannot perform solid-liquid separation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-clogging filter includes a mounting plate, with solid-liquid separation mechanisms on both the left and right sides of the interior of the mounting plate, a filter screen slidably connected inside the mounting plate, a bottom pipe fixedly connected to the bottom of the mounting plate, and a removal mechanism slidably connected to both the left and right sides of the exterior of the mounting plate.

[0008] The solid-liquid separation mechanism includes a groove, a fixed rod fixedly connected inside the groove, an installation spring sleeved on the outside of the fixed rod, installation sliders fixedly connected to the left and right sides of the filter screen, an extension rod fixedly connected to the bottom of the filter screen, a squeezing plate fixedly connected to the bottom of the extension rod, a cross mounting plate fixedly connected to the bottom of the bottom pipe, an installation housing fixedly connected to the top of the cross mounting plate, a spring limiting component slidably connected inside the installation housing, a sealing plate fixedly connected to the top of the spring limiting component, a sealing component fixedly connected to the top of the bottom pipe, and the groove is formed on the left and right sides inside the installation plate.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] The sealing assembly includes a sealing ring, the outer side of which contacts the outer side of the sealing plate, and the outer side of the sealing ring is fixedly connected to the inner top end of the bottom pipe;

[0013] As a further description of the above technical solution:

[0014] The removal mechanism includes a sliding lever, a pull plate fixedly connected to the outside of the sliding lever, cavities on both the left and right sides of the inside of the mounting plate, limit blocks slidably connected inside the cavities, a tension spring sleeved on the outside of the sliding lever, and the outside of the sliding lever slidably connected to the left and right sides inside the mounting plate.

[0015] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the extension rod drives the extrusion plate to extrude the sealing plate, which in turn enables the sealing plate to drive the sliding rod to slide inside the mounting housing, thereby extruding the return spring and causing it to deform. This allows the liquid to flow out through the cross mounting plate, thus achieving solid-liquid separation of the cleaning residue.

[0025] 2. In this utility model, the sliding lever can then slide inside the cavity through the limiting block, which in turn allows the cavity to compress the tension spring, causing the tension spring to deform. This allows the sliding lever to separate from the outside of the filter screen, at which point the residue inside the filter screen can be removed, thus enabling the filter screen to be disassembled and the residue removed.

Detailed Implementation

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an anti-clogging filter, including a mounting plate 1. The mounting plate 1 is circular in shape, and its size is designed according to actual usage requirements and installation space. The surface of the mounting plate 1 is finely processed to ensure that the flatness and smoothness meet the requirements, so as to ensure tight connection and sealing with other components. Solid-liquid separation mechanisms are provided on both the left and right sides inside the mounting plate 1. A filter screen 5 is slidably connected inside the mounting plate 1. The surface of the filter screen 5 is specially treated to give it a certain degree of hydrophilicity or hydrophobicity to improve filtration efficiency and prevent clogging. A bottom pipe 9 is fixedly connected to the bottom of the mounting plate 1. The bottom pipe 9 is used to discharge the filtered liquid to ensure good sealing and corrosion resistance. A removal mechanism is slidably connected to both the left and right sides outside the mounting plate 1. The removal mechanism includes a sliding lever 17. The surface of the sliding lever 17 is finely processed to ensure that it can slide smoothly inside the mounting plate 1 without jamming. A pull plate 21 is fixedly connected to the outside of the sliding lever 17.

[0034] The pull plate 21 is circular in shape and its size is designed according to ergonomic principles to facilitate the operator's grip and pull. The installation plate 1 has cavities 18 on both the left and right sides inside. The shape and size of the cavity 18 are adapted to the limiting block 19, providing sliding space for the limiting block 19. The limiting block 19 is slidably connected inside the cavity 18. Its function is to limit the sliding lever 17 when the dismantling mechanism is working, preventing it from sliding excessively or detaching from the installation plate 1. The surface of the limiting block 19 is smoothed to reduce friction with the inner wall of the cavity 18. The sliding lever 17 is fitted with a tension spring 20. When the operator pulls the pull plate 21, the tension spring 20 is stretched and stores elastic potential energy. When the pull plate 21 is released, the tension spring 20 releases the elastic potential energy, allowing the sliding lever 17 to return to its initial position. The sliding lever 17 is slidably connected to the left and right sides inside the installation plate 1.

[0035] The solid-liquid separation mechanism includes a groove 2. The inner wall of the groove 2 is finely polished to reduce friction on subsequent installation components and ensure smooth installation and operation. A fixing rod 3 is fixedly connected inside the groove 2. The surface of the fixing rod 3 is polished to further reduce friction with the mounting spring 4. The mounting spring 4 is sleeved on the outside of the fixing rod 3. The function of the mounting spring 4 is to provide a certain elastic support for the filter screen 5, so that it can adapt to the impact force brought by the liquid flow during operation. It also plays an auxiliary role in disassembling and installing the filter screen 5. Mounting sliders 6 are fixedly connected to the left and right sides of the filter screen 5. The mounting sliders 6 are connected to the inside of the mounting plate 1. The pre-set slide rails allow the filter screen 5 to slide smoothly within the mounting plate 1, facilitating installation, disassembly, and maintenance. An extension rod 7 is fixedly connected to the bottom of the filter screen 5, and a pressing plate 8 is fixedly connected to the bottom of the extension rod 7. The function of the pressing plate 8 is to cooperate with the elastic limiting component below after the filter screen 5 is installed in place, ensuring the stability of the filter screen 5, and at the same time playing a certain role in buffering and sealing when the liquid flows. A cross mounting plate 10 is fixedly connected to the bottom end of the bottom pipe 9. The function of the cross mounting plate 10 is to provide a stable mounting base for the mounting housing 11. The mounting housing 11 is fixed to the top of the cross mounting plate 10 by bolts.

[0036] A mounting housing 11 is fixedly connected to the top of the cross mounting plate 10. An elastic limiting assembly is slidably connected inside the mounting housing 11. The elastic limiting assembly includes a limiting plate 12, which is circular and has a diameter slightly smaller than the inner diameter of the mounting housing 11. The surface of the limiting plate 12 is polished to form a good sliding fit with the inner wall of the mounting housing 11, allowing it to slide smoothly inside the mounting housing 11. A sliding rod 13 is fixedly connected to the top of the limiting plate 12. The sliding rod 13 is cylindrical and its length is determined according to the height of the mounting housing 11 and the installation requirements of the sealing plate 15. A return spring 14 is sleeved on the outside of the sliding rod 13. The function of the return spring 14 is to store elastic potential energy when subjected to external force. When the external force disappears, it pushes the limiting plate 12 and the sliding rod 13 to return to their original positions. A sealing plate 15 is fixedly connected to the top of the sliding rod 13.

[0037] The sealing plate 15, together with the lower limiting plate 12, sliding rod 13 and return spring 14, form an elastic limiting assembly, which plays a dual role of sealing and limiting. The outer side of the limiting plate 12 is slidably connected to the inside of the mounting housing 11. The top of the elastic limiting assembly is fixedly connected to the sealing plate 15. The top of the bottom pipe 9 is fixedly connected to the sealing assembly. The sealing assembly includes a sealing ring 16. The sealing plate 15 re-closes tightly with the sealing ring 16 to prevent liquid backflow. Throughout the process, the mounting spring 4 continuously provides the filter screen 5 with the elastic force of buffering and resetting, ensuring the stable operation of the filter screen 5. The mounting slider 6 ensures the smooth sliding of the filter screen 5 in the mounting plate 1. All components work together to efficiently complete the solid-liquid separation task. The outer side of the sealing ring 16 contacts the outer side of the sealing plate 15. The outer side of the sealing ring 16 is fixedly connected to the top of the inside of the bottom pipe 9. The outer side of the groove 2 is opened on the left and right sides inside the mounting plate 1.

[0038] Reference Figures 2 to 4 The outer surface of the extrusion plate 8 contacts the outer surface of the sealing plate 15. The outer surface of the extrusion plate 8 is slidably connected to the inside of the bottom pipe 9. The pressure of the solid-liquid mixture is transmitted to the extension rod 7 through the filter screen 5, and then to the extrusion plate 8 through the extension rod 7, so that the extrusion plate 8 and the sealing plate 15 are tightly fitted together, preventing the liquid from flowing out directly through the bottom pipe 9 without filtration. The outer bottom end of the filter screen 5 contacts the outer top end of the bottom pipe 9. The extrusion plate 8 moves up and down with the pressure change of the solid-liquid mixture, thereby controlling the contact state between the sealing plate 15 and the sealing ring 16, and realizing the control of the liquid. The flow of the fluid is controlled by the external sliding connection of the mounting slider 6 to the inside of the groove 2, the external sliding connection of the limiting block 19 to the inside of the mounting plate 1, the external sliding connection of the sliding lever 17 to the inside of the cavity 18, and one end of the tension spring 20 fixedly connected to the outside of the limiting block 19 and the other end of the tension spring 20 fixedly connected to the inside of the limiting block 19. This ensures that when the operator pulls the pull plate 21, the tension spring 20 can store sufficient elastic potential energy and can quickly release the elastic potential energy when the pull plate 21 is released, so that the sliding lever 17 and the limiting block 19 return to their initial positions.

[0039] Working principle: When performing solid-liquid separation on cleaning residue, the residue first enters the interior of the filter screen 5 and remains inside the filter screen 5. At this moment, the residue, due to its presence inside the filter screen 5, causes the filter screen 5 to be subjected to gravity. This gravity, through the extension rod 7, causes the pressing plate 8 to press the sealing plate 15. This allows the sealing plate 15 to move the sliding rod 13 inside the mounting housing 11, which in turn causes the return spring 14 to be compressed. This causes the return spring 14 to deform, allowing the liquid to flow out through the cross mounting plate 10, thus achieving solid-liquid separation of the cleaning residue.

[0040] When removing the residue inside the filter screen 5, by pulling the pull plate 21, the pull plate 21 can slide on the left and right sides of the outside of the mounting plate 1 via the sliding latch 17. Then, the sliding latch 17 can slide inside the cavity 18 via the limiting block 19. Then, the cavity 18 can compress the tension spring 20, causing the tension spring 20 to deform. Then, the sliding latch 17 can separate from the outside of the filter screen 5. At this time, the residue inside the filter screen 5 can be removed, thus realizing the disassembly and removal of the residue from the filter screen 5.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
