Description

Technical Field

[0001] This utility model relates to the field of carbon rod filter technology, and in particular to a carbon rod filter with grooved guidance. Background Technology

[0002] A water purifier is a water treatment device that performs deep filtration and purification of water. It effectively removes harmful substances from water, such as bacteria, viruses, heavy metals, and pesticide residues, reducing the risk of illness from drinking unclean water and providing people with safer and healthier drinking water. Carbon filter cartridges are an important component in water purifiers used for filtering and purifying water. Their main material is activated carbon, which is typically made from raw materials such as coconut shells, fruit shells, and coal.

[0003] Existing technology, patent number CN221071112U, discloses a grooved carbon rod filter element. By providing several external grooves on the outer side of the carbon rod filter element body, the surface area of ​​the carbon rod filter element body is increased, improving filtration efficiency. Simultaneously, the external groove design allows water to more easily penetrate into the interior of the carbon rod filter element body, reducing filtration resistance and water pressure loss. Furthermore, the external grooves increase the dirt-holding capacity, making the carbon rod filter element body more robust and extending its service life. However, in actual use, water flows through the second and first filter layers for preliminary filtration, and the filtered water is discharged through a drain pipe. This makes it inconvenient to change the size of the outlet. In daily household use, sometimes a large amount of filtered water is needed quickly for washing vegetables and laundry; while in scenarios with extremely high water quality requirements, such as laboratory water use, a smaller flow rate is needed to ensure more thorough filtration. The fixed size of the carbon rod filter element's outlet cannot flexibly adjust the flow rate according to actual needs, resulting in situations where the flow rate is too high, leading to insufficient filtration, or too low, failing to meet usage requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a carbon rod filter element with grooved guidance.

[0005] This utility model is achieved through the following technical solution:

[0006] A grooved carbon rod filter element includes an outer coarse filter layer, a connecting plate, an activated carbon adsorption layer, a high-precision filter layer, and an ion exchange layer. One side of the connecting plate is in contact with the outer coarse filter layer. The activated carbon adsorption layer is movably disposed inside the outer coarse filter layer. The high-precision filter layer is movably disposed inside the activated carbon adsorption layer. The ion exchange layer is movably disposed inside the high-precision filter layer. A first perforated plate is fixedly connected inside the connecting plate. An adjustment component is provided on one side of the first perforated plate. The adjustment component includes a second perforated plate, a rotating shaft, and a handle. One side of the second perforated plate is in contact with the ion exchange layer. One end of the rotating shaft extends into the interior of the second perforated plate, and the other end of the rotating shaft passes through the activated carbon adsorption layer, the high-precision filter layer, and the ion exchange layer and is fixedly connected to the handle.

[0007] Optionally, in one possible implementation, a friction ring is movably sleeved on the handle, and one side of the friction ring is fixedly connected to the outer coarse filter layer, wherein the friction ring serves to increase the friction between the handle and the outer coarse filter layer.

[0008] Optionally, in one possible implementation, a bolt is provided on the other side of the second perforated plate, and the second perforated plate is fixed to the rotating shaft by the bolt. It can be seen that in the above technical solution, rotating the bolt away from the rotating shaft releases the fixation between the rotating shaft and the second perforated plate, allowing the second perforated plate to be disassembled and replaced.

[0009] Optionally, in one possible implementation, the outer coarse filter layer has multiple grooves on its outer side, wherein the grooves serve to guide the direction and distribution of water flow.

[0010] Optionally, in one possible implementation, an externally threaded sleeve is fixedly fitted on the outer side of the outer coarse filter layer, and a connecting sleeve is threaded onto the outer side of the externally threaded sleeve, with one end of the connecting sleeve fixedly connected to a connecting plate. It can be seen that the above technical solution facilitates the disassembly and replacement of the activated carbon adsorption layer, the high-precision filter layer, and the ion exchange layer.

[0011] Optionally, in one possible implementation, a gasket is movably disposed inside the connecting sleeve, and both ends of the gasket are in contact with the connecting plate and the outer coarse filter layer, respectively. It can be seen that the above technical solution facilitates improved sealing between the outer coarse filter layer and the connecting plate.

[0012] Optionally, in one possible implementation, a plurality of locking posts are fixedly connected to one side of the connecting plate, and one end of each locking post extends into the interior of the activated carbon adsorption layer and the high-precision filtration layer, respectively. It can be seen that the above technical solution facilitates the positioning of the activated carbon adsorption layer and the high-precision filtration layer.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention reduces the impact of water flow on the activated carbon adsorption layer, high-precision filter layer, and ion exchange layer through the groove. Turning the handle drives the rotating shaft to rotate, which in turn drives the second mesh plate to rotate. The position of the second mesh plate can be adjusted as needed so that the holes on the second mesh plate and the first mesh plate do not overlap, thereby adjusting the size of the water outlet. It is simple to operate and has a wide range of applications.

[0015] Meanwhile, by sequentially placing the activated carbon adsorption layer, high-precision filtration layer, and ion exchange layer into the outer coarse filtration layer, and then rotating the outer coarse filtration layer so that the external threaded sleeve extends into the connecting sleeve, the connecting plate is fixed to the outer coarse filtration layer. The gasket can improve the sealing between the outer coarse filtration layer and the connecting plate. The structure is simple and easy to use. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example 1:

[0025] like Figure 1-5 As shown, a grooved carbon rod filter element includes an outer coarse filter layer 1, a connecting plate 2, an activated carbon adsorption layer 7, a high-precision filter layer 8, and an ion exchange layer 9. One side of the connecting plate 2 is in contact with the outer coarse filter layer 1. The activated carbon adsorption layer 7 is movably disposed inside the outer coarse filter layer 1, the high-precision filter layer 8 is movably disposed inside the activated carbon adsorption layer 7, and the ion exchange layer 9 is movably disposed inside the high-precision filter layer 8. A first mesh plate 6 is fixedly connected inside the connecting plate 2. An adjustment component 5 is provided on one side of the first mesh plate 6. The adjustment component 5 includes a second mesh plate 501, a rotating shaft 502, and a handle 503. One side of the second mesh plate 501 is in contact with the ion exchange layer 9. One end of the rotating shaft 502 extends into the interior of the second mesh plate 501, and the other end of the rotating shaft 502 passes through the activated carbon adsorption layer 7, the high-precision filter layer 8, and the ion exchange layer 9 and is fixedly connected to the handle 503.

[0026] Furthermore, a friction ring 504 is movably sleeved on the handle 503, and one side of the friction ring 504 is fixedly connected to the outer coarse filter layer 1. The friction ring 504 serves to increase the friction between the handle 503 and the outer coarse filter layer 1. A bolt 505 is provided on the other side of the second mesh plate 501, and the second mesh plate 501 is fixed to the rotating shaft 502 by the bolt 505. Multiple grooves are opened on the outer side of the outer coarse filter layer 1, and the grooves serve to guide the direction and distribution of water flow.

[0027] The usage process of this utility model embodiment is as follows:

[0028] During use, when water flows through the carbon rod filter element, the grooves allow the water to contact all parts of the filter element more evenly, preventing water from concentrating in certain areas and causing insufficient filtration in other areas. Simultaneously, the grooves also act as a buffer, reducing the impact of the water flow on the activated carbon adsorption layer 7, the high-precision filtration layer 8, and the ion exchange layer 9, protecting their stability. The connecting plate 2 is installed on the water purifier using bolts. The water flows through the outer coarse filtration layer 1 and comes into contact with the activated carbon adsorption layer 7, the high-precision filtration layer 8, and the ion exchange layer 9, finally passing through the first mesh plate 6. The water is discharged from the second perforated plate 501, forming a complete water channel. Rotating the handle 503 drives the rotating shaft 502 to rotate, which in turn drives the second perforated plate 501 to rotate. The position of the second perforated plate 501 can be adjusted as needed so that the small holes on the second perforated plate 501 and the first perforated plate 6 do not overlap, thereby adjusting the size of the water outlet. The operation is simple and the application range is wide. The friction ring 504 can increase the friction between the handle 503 and the outer coarse filter layer 1. Rotating the bolt 505 and moving it away from the rotating shaft 502 will release the fixation between the rotating shaft 502 and the second perforated plate 501, allowing the second perforated plate 501 to be disassembled and replaced.

[0029] Example 2:

[0030] like Figure 1 , 2 As shown in Figures 3 and 5, a grooved carbon rod filter element has an external threaded sleeve 4 fixedly sleeved on the outer side of the outer coarse filter layer 1. The outer side of the external threaded sleeve 4 is threadedly connected to a connecting sleeve 3, and one end of the connecting sleeve 3 is fixedly connected to a connecting plate 2. A gasket 11 is movably arranged inside the connecting sleeve 3, and both ends of the gasket 11 are in contact with the connecting plate 2 and the outer coarse filter layer 1, respectively. A plurality of locking posts 10 are fixedly connected to one side of the connecting plate 2, and one end of the plurality of locking posts 10 extends into the interior of the activated carbon adsorption layer 7 and the high-precision filter layer 8, respectively.

[0031] The activated carbon adsorption layer 7, high-precision filter layer 8, and ion exchange layer 9 are sequentially placed inside the outer coarse filter layer 1. Multiple locking posts 10 can limit the movement of the activated carbon adsorption layer 7 and the high-precision filter layer 8. Then, the outer coarse filter layer 1 is rotated so that the external threaded sleeve 4 extends into the connecting sleeve 3, thereby fixing the connecting plate 2 to the outer coarse filter layer 1. The gasket 11 can improve the sealing between the outer coarse filter layer 1 and the connecting plate 2. Similarly, the outer coarse filter layer 1 can be disassembled. The activated carbon adsorption layer 7 is made of melt-blown PP cotton and is mainly used to intercept large particulate impurities in the water, such as silt, rust, and suspended solids. The high-precision filter layer 8 is made of high-precision PP cotton and can filter out finer particles, colloids, and other impurities in the water. The ion exchange layer 9 contains ion exchange resin and other materials, and its main function is to remove some harmful ions in the water through ion exchange reactions. It has a simple structure and is easy to use.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
