Description

Technical Field

[0001] This invention relates to the field of filtration equipment technology, and in particular to a modular filter cartridge that facilitates the addition of natural mineral water flavoring filter media. Background Technology

[0002] Modular filter cartridges are modular filtration devices composed of multiple independent filtration units. Their core design concept lies in achieving efficient filtration and convenient maintenance through a modular structure. Multiple units possess independent filtration functions (such as activated carbon adsorption, ceramic interception, and polymer material separation). Users can flexibly combine modules with different functions to achieve multi-stage or targeted filtration according to their needs. Mineral filter media (such as basalt, maifanite, volcanic rock, etc.) are rich in minerals such as metasilicic acid, magnesium, calcium, and potassium. Through physical adsorption and ion exchange, mineral filter media can slowly release minerals, giving water a clear, sweet taste, neutralizing the "hardness" of the water, and making it "soft" and smooth.

[0003] Conventional filter cartridges typically use a fixed-diameter feed port. Adding large-particle mineral filter media can easily result in accidental spillage, affecting the feeding efficiency. Conventional filter cartridges rely on manual estimation of the amount to be added, and uneven accumulation of filter media can easily affect the estimation of the amount to be added, leading to insufficient reserved expansion space. This may result in excessive internal pressure, structural deformation, or even leakage of the filter cartridge. Therefore, a modular filter cartridge that facilitates the addition of natural mineral water flavoring filter media is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the existing technology, such as the easy spillage of large-particle mineral filter media, which affects the filling efficiency; the reliance on manual estimation of the amount to be added in conventional filter cartridges, which leads to uneven accumulation of filter media, which can affect the estimation of the amount to be added, resulting in insufficient reserved expansion space, which may lead to excessive internal pressure, structural deformation or even leakage of the filter cartridge. The invention proposes a modular filter cartridge that is easy to add natural mineral water flavor filter media.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A modular filter cartridge for easy addition of natural mineral water flavoring filter media includes a cylindrical body. A cap is mounted on the upper part of the cylindrical body, and an inlet is mounted on the upper part of the cap. An outlet is mounted on the bottom of the cylindrical body. An annular plate is slidably disposed on the inner side of the cylindrical body. Multiple guide plates are rotatably connected to the upper part of the annular plate. Connecting plates are slidably disposed on the sides of the guide plates. When the annular plate moves upward, the multiple guide plates unfold, and simultaneously, the connecting plates extend and contact adjacent guide plates. The multiple connecting plates and guide plates together form a conical shroud, enlarging the diameter of the feed inlet and improving the filter media addition efficiency. A limiting component is provided inside the cylindrical body. The component includes a limiting plate movably connected to the inside of the cylinder, a rotating ring rotatably connected to the inside of the cylinder, a movable ring movably connected to the inside of the rotating ring, and a threaded rod threadedly connected to the inside of the movable ring. Rotating the threaded rod pushes the limiting plate upward, turning the part above the limiting plate inside the cylinder into a filter media addition area. This allows for precise control of the amount of filter media added and provides space for future expansion. Simultaneously, the threaded rod continuously pushes the limiting plate, and the back-and-forth rotation of the rotating ring drives the movable ring and the threaded rod to push the limiting plate up and down, causing slight vibrations in the filter media during addition. This ensures uniform accumulation of the filter media and further improves the accuracy of the addition amount.

[0006] The above technical solution further includes: An annular groove is provided on the inner side of the cylinder, and multiple first telescopic rods are installed on the inner side of the annular groove. The ends of the multiple first telescopic rods are fixedly connected to the annular plate. The size of the opening of the annular groove is adapted to the size of the annular plate.

[0007] Multiple first support plates are installed on the upper part of the annular plate. A rotating rod is installed on the side of the first support plate. The end of the rotating rod away from the first support plate is rotatably connected to a guide plate. A torsion spring is installed between the guide plate and the first support plate. The torsion spring is sleeved on the outside of the rotating rod. A protective ring is installed on the side of the first support plate near the guide plate. When the torsion spring resets, it drives the rotating rod to rotate and resets the guide plate. The protective ring protects the torsion spring.

[0008] The guide plate has an opening groove inside, and a second telescopic rod is installed inside the opening groove. The end of the second telescopic rod is fixedly connected to the connecting plate, and the connecting plate is slidably connected to the opening groove.

[0009] The side of the cylinder is provided with a sliding groove, which is connected to the annular groove. A sliding block is slidably arranged inside the sliding groove. The side of the sliding block is fixedly connected to the annular plate. A pull ring is installed on the side of the sliding block away from the annular plate. When the pull ring moves, it drives the sliding block to move along the sliding groove.

[0010] A third telescopic rod is installed on the inner side of the cylinder. The upper end of the third telescopic rod is fixedly connected to the limiting plate. After the filter material expands, it drives the limiting plate to move down, at which time the third telescopic rod retracts.

[0011] The threaded rod is rotatably connected to a rotating plate at one end near the limiting plate, and the rotating plate is in contact with the limiting plate. A rotating handle is installed at the end of the threaded rod.

[0012] A second support plate is installed on the inner side of the cylinder. A limit rod is installed on the side of the second support plate near the movable ring. The limit rod is slidably connected to the movable ring.

[0013] The inner side of the rotating ring is provided with a guide groove, and the outer side of the movable ring is provided with a guide rod. The guide rod is movably connected to the guide groove. The size of the opening of the guide groove is adapted to the size of the guide rod. The movable ring is driven to move back and forth along the limiting rod by the guiding action of the guide groove.

[0014] The present invention has the following beneficial effects: 1. In this invention, when the cylinder cover is opened, multiple guide plates automatically unfold and simultaneously push the connecting plate outward. The multiple connecting plates and guide plates together form a conical cover, which expands the diameter of the feeding port and improves the filter material addition efficiency.

[0015] 2. In this invention, when the threaded rod is rotated, the rotating plate pushes the limiting plate upward, turning the part above the limiting plate inside the cylinder into the filter material addition area. This allows for precise control of the amount of filter material added, facilitating the leaving of space for the filter material to expand later. At the same time, the threaded rod continuously pushes the limiting plate, causing the filter material to vibrate slightly during the addition process, ensuring uniform accumulation of the filter material and further improving the accuracy of the addition amount.

[0018] 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.

[0019] Example 1 like Figure 1 - Figure 9As shown, the modular filter cartridge proposed in this invention, which facilitates the addition of natural mineral water flavoring filter media, includes a cylindrical body 1. A cap 2 is installed on the upper part of the cylindrical body 1, and a water inlet 3 is installed on the upper part of the cap 2. A water outlet 4 is installed on the bottom of the cylindrical body 1. An annular plate 7 is slidably disposed on the inner side of the cylindrical body 1. Multiple guide plates 11 are rotatably connected to the upper part of the annular plate 7. Connecting plates 19 are slidably disposed on the sides of the guide plates 11. When the annular plate 7 moves upward, the multiple guide plates 11 unfold, and simultaneously, the connecting plates 19 extend and contact adjacent guide plates 11. The multiple connecting plates 19 and guide plates 11 together form a conical shroud, increasing the diameter of the feeding port and improving the filter media addition efficiency. A limiting component is provided inside the cylindrical body 1. The positioning component includes a limiting plate 29 movably connected to the inner side of the cylinder 1, a rotating ring 20 rotatably connected to the inner side of the cylinder 1, a movable ring 22 movably connected to the inner side of the rotating ring 20, and a threaded rod 23 threadedly connected to the inner side of the movable ring 22. Rotating the threaded rod 23 pushes the limiting plate 29 upward, turning the part above the limiting plate 29 inside the cylinder 1 into a filter media addition area. This allows for precise control of the amount of filter media added, facilitating the allowance for future expansion of the filter media. Simultaneously, the threaded rod 23 continuously pushes the limiting plate 29, and the back-and-forth rotation of the rotating ring 20 drives the movable ring 22 and the threaded rod 23 to push the limiting plate 29 up and down, causing the filter media to vibrate slightly during the addition process, ensuring uniform accumulation of the filter media and further improving the accuracy of the addition amount.

[0020] The inner side of the cylinder 1 is provided with an annular groove 5, and a plurality of first telescopic rods 6 are installed on the inner side of the annular groove 5. The ends of the plurality of first telescopic rods 6 are fixedly connected to the annular plate 7. The size of the opening of the annular groove 5 is adapted to the size of the annular plate 7.

[0021] Multiple first support plates 8 are installed on the upper part of the annular plate 7. A rotating rod 10 is installed on the side of the first support plate 8. The end of the rotating rod 10 away from the first support plate 8 is rotatably connected to the guide plate 11. A torsion spring 12 is installed between the guide plate 11 and the first support plate 8. The torsion spring 12 is sleeved on the outside of the rotating rod 10. A protective ring 13 is installed on the side of the first support plate 8 near the guide plate 11. When the torsion spring 12 resets, it drives the rotating rod 10 to rotate and resets the guide plate 11. The protective ring 13 protects the torsion spring 12.

[0022] The guide plate 11 has an opening groove 17 inside, and a second telescopic rod 18 is installed on the inner side of the opening groove 17. The end of the second telescopic rod 18 is fixedly connected to the connecting plate 19, and the connecting plate 19 is slidably connected to the opening groove 17.

[0023] The side of the cylinder 1 is provided with a sliding groove 14, which is connected to the annular groove 5. A sliding block 15 is slidably arranged on the inner side of the sliding groove 14. The side of the sliding block 15 is fixedly connected to the annular plate 7. A pull ring 16 is installed on the side of the sliding block 15 away from the annular plate 7. When the pull ring 16 moves, it drives the sliding block 15 to move along the sliding groove 14.

[0024] In this embodiment, when it is necessary to add filter material to the inner side to enhance the taste of natural mineral water, the cylinder cover 2 can be opened. At this time, the cylinder cover 2 no longer limits the multiple guide plates 11, and the first telescopic rod 6, which is in a retracted state, resets, simultaneously driving the annular plate 7 to reset, causing the annular plate 7 to move to the upper part of the annular groove 5. At this time, the guide plate 11 moves completely to the outside of the annular groove 5, and the multiple torsion springs 12, which are in a retracted state, reset, simultaneously driving the rotating rod 10 to rotate and reset the guide plate 11. At this time, the angle between the guide plate 11 and the annular plate 7 is seventy-five degrees. The second telescopic rod 18, which is in the retracted state, is reset, thereby driving the connecting plate 19 to move outward of the opening groove 17 until the connecting plate 19 contacts the adjacent guide plate 11. The multiple guide plates 11 and the connecting plate 19 form a conical cover, increasing the opening when adding material, which facilitates the addition of filter material. After the addition is completed, the sliding pull ring 16 can be slid down to move it. When the pull ring 16 moves down, it drives the sliding block 15 to move down along the sliding groove 14, and at the same time drives the annular plate 7 to move to the inside of the outlet 4. Then the guide plate 11 is retracted to the inside of the outlet 4, and then the upper cylinder cover 2 is installed.

[0025] Example 2 like Figure 1 - Figure 9 As shown, based on Embodiment 1, a third telescopic rod 28 is installed on the inner side of the cylinder 1. The upper end of the third telescopic rod 28 is fixedly connected to the limiting plate 29. After the filter material expands, it drives the limiting plate 29 to move down, at which time the third telescopic rod 28 retracts.

[0026] The threaded rod 23 is rotatably connected to a rotating plate 24 at one end near the limiting plate 29. The rotating plate 24 is in contact with the limiting plate 29. A rotating handle 27 is installed at the end of the threaded rod 23.

[0027] A second support plate 9 is installed on the inner side of the cylinder 1. A limit rod 21 is installed on the side of the second support plate 9 near the movable ring 22. The limit rod 21 is slidably connected to the movable ring 22.

[0028] The inner side of the rotating ring 20 is provided with a guide groove 25, and the outer side of the movable ring 22 is provided with a guide rod 26. The guide rod 26 is movably connected to the guide groove 25. The size of the opening of the guide groove 25 is adapted to the size of the guide rod 26. The movable ring 22 is driven to move back and forth along the limiting rod 21 by the guiding action of the guide groove 25.

[0029] In this embodiment, when feeding is required, the feeding capacity is limited according to the characteristics of the ore. At this time, the threaded rod 23 can be rotated by rotating the handle 27. The force generated by the rotation of the threaded rod 23 can drive the limiting plate 29 to move upward through the rotating plate 24. At this time, the third telescopic rod 28 is stretched. At this time, the part of the cylinder 1 above the limiting plate 29 is the filter material feeding area, which can accurately control the amount of filter material added. When adding filter material, the rotating ring 20 can be rotated back and forth. When the rotating ring 20 rotates back and forth, the guide groove 25 drives the movable ring 22 to move back and forth along the limiting rod 21. At the same time, the threaded rod 23 and the rotating plate 24 continuously push the limiting plate 29. The limiting plate 29 is pushed and the force is transmitted to the filter material, causing the filter material to shake and rearrange continuously, ensuring that the filter material is evenly piled in the cylinder 1. After the filter material is added, the threaded rod 23 is rotated in the opposite direction and the rotating plate 24 is moved to the upper part of the movable ring 22 and contacts the movable ring 22.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
