Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a water filter cap and its activated carbon filter. Background Technology

[0002] Water filter caps are essential water filtration elements for sand filters and various media filters.

[0003] The prior art discloses a combined water filter cap for a filter (publication number: CN110681191A), which includes a cap body, a force-bearing rod that runs through the cap body, and a bottom cover, a backstop washer and a locking nut that are sequentially fitted on the surface of the force-bearing rod and located below the cap body from top to bottom. The force-bearing rod is provided with a limit groove.

[0004] In the existing technology, by setting a cap and a filter handle, the filter handle passes through the cap and the water entering the cap enters the cavity of the filter handle through the water groove on the side wall of the filter handle. Due to the limited diameter of the filter handle, the size of the water groove is small, which is not conducive to the water entering the cavity of the filter handle and restricts the water flow. There is room for optimization.

[0005] Therefore, we propose a water filter cap and its activated carbon filter. Utility Model Content

[0006] The present invention mainly addresses the technical problem of low water flow caused by the limited size of the water tank in the filter handle, and provides a water filter cap and its activated carbon filter.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a water filter cap, comprising:

[0008] The cap and filter handle, wherein the cap forms an umbrella-shaped structure and the circumference of the cap has several water inlet grooves;

[0009] A connecting assembly is provided between the cap and the filter handle for assembling and disassembling the cap. The connecting assembly includes a limiting plate, a stop block, ribs, and a screw. Several ribs are fixedly connected to the bottom of the stop block. The ribs are fixedly connected to the limiting plate, and a leakage channel is formed between two adjacent ribs. The filter handle passes through the limiting plate. The screw is threadedly connected to the stop block and presses the cap tightly against the top of the limiting plate.

[0010] In a preferred embodiment of this utility model, the limiting plate is formed into a circular plate, and an integrally formed annular baffle is fixedly provided on the top of the limiting plate. The lower end of the cap is inserted into the annular baffle and abuts against the top surface of the limiting plate.

[0011] In a preferred embodiment of this utility model, the limiting plate and the filter handle are integrally formed, the upper end face of the filter handle is flush with the top plate of the limiting plate, and the upper end of the filter handle is open.

[0012] In a preferred embodiment of this utility model, the stop block is formed into a circular cylindrical structure, with a threaded hole at the upper end of the stop block and an insertion hole adapted to the stop block at the upper end of the cap. The stop block extends through the insertion hole to be flush with the top surface of the cap.

[0013] In a preferred embodiment of this utility model, the ribs are formed into spiral-shaped columns, with the upper end of the ribs fixedly connected to the bottom of the stop block and the lower end of the ribs fixedly connected to the top surface of the limiting plate. Several identical ribs are distributed in a circular array on the top of the limiting plate.

[0014] In a preferred embodiment of this utility model, the connecting assembly further includes a support rod and a support ring, and the top of the limiting plate is also fixed with several support rods. The support ring is fixedly connected to the support rods and supports the inner wall of the limiting plate.

[0015] In a preferred embodiment of this utility model, the support ring forms a ring structure, and several support rods are equidistantly arranged at the bottom of the support ring, with the support rods distributed in a ring array around each rib.

[0016] An activated carbon filter includes a filter body, the bottom of which is provided with all of the aforementioned filter caps.

[0017] This utility model provides a water filter cap and its activated carbon filter. It has the following beneficial effects:

[0018] 1. This water filter cap and its activated carbon filter feature a detachable cap head for easy removal, cleaning, and maintenance. Furthermore, by incorporating several ribs between the stop block and the limiting plate, and creating several identical leakage channels through the gaps between the ribs, the resistance to water entering the filter handle is significantly reduced, resulting in a higher water intake. Additionally, the grid structure formed by multiple ribs further blocks impurities in the water, leading to superior filtration.

[0019] 2. This water filter cap and its activated carbon filter, by setting support rods and support rings, when the screw and the stop block are fastened, the support rods support the support rings so that the support rings abut against the inner wall of the cap head. The support rings can support the middle position inside the cap head, thereby strengthening the support of the cap head. When subjected to water pressure, the cap head has sufficient support strength to ensure the stability of the overall structure and prevent it from collapsing or deforming excessively. At the same time, multiple support rods ensure that water can easily enter the filter handle cavity, and multiple support rods form a fence, which, together with multiple ribs forming another fence, has multiple filtration effects.

[0020] 3. The water filter cap and its activated carbon filter, by setting the above-mentioned water filter cap, make the water filter more effective at filtering water. Secondly, the filter cap can be easily disassembled and cleaned, making it easy to maintain. Attached Figure Description

[0027] A water filter cap and its activated carbon filter, such as Figure 1 and Figure 2 As shown, it includes:

[0028] The cap 10 and the filter handle 11 are arranged in an umbrella-shaped structure. Several water inlet grooves are provided around the circumference of the cap 10. The water inlet grooves are rectangular and their length is less than the arc length of the cap 10. The bottom of the cap 10 is open and the top of the cap 10 is closed. Impurities are blocked by the several water inlet grooves around the circumference of the cap 10. This will not be described in detail here.

[0029] like Figure 3 and Figure 4As shown, a connecting assembly is disposed between the cap 10 and the filter handle 11 for assembling and disassembling the cap 10. The connecting assembly includes a limiting plate 12, a stop block 20, ribs 21, and a screw 22. Several ribs 21 are fixedly connected to the bottom of the stop block 20. The ribs 21 are fixedly connected to the limiting plate 12, and a leakage channel is formed between two adjacent ribs 21. The filter handle 11 passes through the limiting plate 12. The screw 22 is threadedly connected to the stop block 20 and presses the cap 10 against the top of the limiting plate 12. The limiting plate 12 is a circular plate, and an integrally formed annular retaining edge is fixedly provided on the top of the limiting plate 12. The lower end of the cap 10 is inserted into the annular retaining edge and abuts against it. The top surface of the limiting plate 12 is integrally formed with the filter handle 11. The upper end of the filter handle 11 is flush with the top plate of the limiting plate 12. The upper end of the filter handle 11 is open. The stop block 20 forms a circular cylindrical structure. The upper end of the stop block 20 is provided with a threaded hole. The upper end of the cap 10 is provided with an insertion hole that fits the stop block 20. The stop block 20 extends through the insertion hole to be flush with the top surface of the cap 10. The rib 21 forms a spiral column. The upper end of the rib 21 is fixedly connected to the bottom of the stop block 20. The lower end of the rib 21 is fixedly connected to the top surface of the limiting plate 12. Several identical ribs 21 are distributed in a ring array on the top of the limiting plate 12.

[0030] In this design, a detachable cap 10 is provided to facilitate removal for cleaning and maintenance. Secondly, by setting several ribs 21 between the stop block 20 and the limiting plate 12, several identical leakage channels are formed through the gaps between the ribs 21, which can greatly reduce the resistance of water entering the filter handle 11 and achieve a higher water intake. Furthermore, the grid structure formed by multiple ribs 21 further blocks impurities in the water, resulting in a better filtration effect.

[0031] like Figure 4 and Figure 5 As shown, the connecting assembly also includes support rods 23 and support rings 24. Several support rods 23 are fixed to the top of the limiting plate 12. The support ring 24 is fixedly connected to the support rods 23 and supports the inner wall of the limiting plate 12. The support ring 24 forms a ring structure. Several support rods 23 are equidistantly arranged at the bottom of the support ring 24. The support rods 23 are distributed in a ring array around each rib 21.

[0032] In this solution, as a supplement to the above solution, by setting support rods 23 and support rings 24, when the screw 22 is fastened to the stop block 20, the support rods 23 support the support rings 24 so that the support rings 24 abut against the inner wall of the cap head 10. The support rings 24 can support the middle position inside the cap head 10, thereby strengthening the support of the cap head 10. When subjected to water pressure, the cap head 10 has sufficient support strength to ensure the stability of the overall structure and prevent collapse and excessive deformation. At the same time, multiple support rods 23, while ensuring that water can easily enter the filter handle 11 cavity, form a fence, which, together with multiple ribs 21, forms another fence, providing multiple filtration effects.

[0033] As not shown in the figure, an activated carbon filter includes a filter body. The bottom of the filter body is provided with all the aforementioned filter caps. Specifically, the bottom of the filter body should be provided with mounting holes, and the filter handle 11 can be locked and fixed by a nut. By setting the aforementioned filter caps, the water filter has a stronger filtration effect on the water. In addition, the filter caps can be easily disassembled and cleaned, making maintenance convenient.

[0034] The working principle of this utility model is as follows: By setting several ribs 21 between the stop block 20 and the limiting plate 12, several identical leakage channels are formed through the gaps between the ribs 21, which can greatly reduce the resistance of water entering the filter handle 11. When the screw 22 is fastened to the stop block 20, the support rod 23 supports the support ring 24 so that the support ring 24 abuts against the inner wall of the cap 10. The support ring 24 can support the middle position inside the cap 10, thereby strengthening the support of the cap 10. When subjected to water pressure, the cap 10 has sufficient support strength to ensure the stability of the overall structure and prevent it from collapsing or deforming excessively.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
