Description

Technical Field

[0001] This utility model relates to the technical field of filter element structure components, and in particular to a leak-proof and easily replaceable carbon fiber water filter element structure. Background Technology

[0002] Carbon fiber water filter cartridges are a type of high-efficiency filter material, primarily made of fibrous carbon material with a carbon content of over 90%. Their structure integrates both physical interception and chemical adsorption: the outer layer of fine fiber filter media intercepts particulate matter, the middle layer of activated carbon fiber cloth adsorbs odors, residual chlorine, heavy metal ions, and organic pollutants, and the inner layer of protective filter media prevents carbon dust leakage. Thanks to the high specific surface area of ​​activated carbon fibers, its adsorption efficiency is more than 80% higher than that of traditional activated carbon. It is widely used in household water purifiers, industrial water treatment, and RO membrane pretreatment.

[0003] For filtration devices equipped with carbon fiber filter cartridges, the cartridges need to be replaced regularly to ensure filtration efficiency. However, during actual installation or replacement, misalignment during installation or aging and deformation of the sealing rings after long-term use often leads to gaps between the filter cartridge and the outer casing. These gaps can cause side leakage of the filter cartridge, allowing unpurified water on the outside of the cartridge to directly connect with the filtered water on the inside, ultimately resulting in secondary pollution of the filtered water and affecting water safety. Based on this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a leak-proof, easily replaceable carbon fiber water filter element structure that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leak-proof, easily replaceable carbon fiber water filter element structure includes a housing and a filter element assembly. The filter element assembly is installed inside the housing. The structure further includes: a second sealing ring at both the top and bottom of the filter element assembly; a rotating base threadedly connected to the bottom of the housing; an adjusting base plate slidably connected to the rotating base; and conical blocks at both the adjusting base plate and the top of the housing. When the conical blocks at the top and bottom clamp the filter element assembly, the filter element assembly is guided to a centered position. The adjusting base plate and the top of the housing together clamp the filter element assembly and the second sealing ring, separating the inner and outer spaces of the filter element assembly.

[0007] Preferably, the top of the outer casing is provided with an inlet pipe and an outlet pipe, with the outlet pipe located at the center of the top of the outer casing.

[0008] Preferably, an adjusting bolt is rotatably connected to the adjusting base plate, the adjusting bolt is connected to the adjusting base plate by threads, and a supporting side plate is provided on the rotating base.

[0009] Preferably, a limiting rod is connected to the adjusting base plate, and the limiting rod is slidably connected to the rotating base.

[0010] Preferably, the top of the outer shell and the adjusting base plate are slidably connected to a sliding member, the sliding member located on the adjusting base plate passes through the rotating base, and the sliding member is provided with a compression spring.

[0011] Furthermore, the sliding member has a through hole, and the top and bottom of the sliding member are respectively provided with water holes, which are connected through the through hole.

[0012] Preferably, the conical block is provided with a first sealing ring, and after the filter element assembly is installed, a sealed space is formed between the first sealing ring and the second sealing ring.

[0014] Compared with the prior art, this utility model provides a leak-proof and easily replaceable carbon fiber water filter element structure, which has the following beneficial effects:

[0015] 1. This leak-proof and easily replaceable carbon fiber water filter element structure allows for easy installation of the filter element assembly without the need for users to perform alignment and positioning operations by setting conical blocks on the adjusting base plate and the top of the outer shell. At the same time, the connection between the water circuit and the outer shell is located on the top of the outer shell, while the rotating base is located on the bottom, thus eliminating the need to disassemble the connecting water pipe when replacing the filter element assembly, simplifying the installation difficulty and steps.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example 1: Refer to Figures 1-7 A leak-proof, easily replaceable carbon fiber water filter element structure includes a housing 1 and a filter element assembly 5. The filter element assembly 5 is installed inside the housing 1. The structure also includes: a second sealing ring 51 at both the top and bottom of the filter element assembly 5; a rotating base 2 threadedly connected to the bottom of the housing 1; an adjusting base plate 21 slidably connected to the rotating base 2; and conical blocks 3 at both the adjusting base plate 21 and the top of the housing 1. When the conical blocks 3 at the top and bottom clamp the filter element assembly 5, the filter element assembly 5 is guided to a centered position. The adjusting base plate 21 and the top of the housing 1 together clamp the filter element assembly 5 and the second sealing ring 51, separating the inner and outer spaces of the filter element assembly 5.

[0030] In this invention, to facilitate user disassembly and replacement of the filter element assembly 5, the connection points between the water passage and the outer shell 1 are all located on the top of the outer shell 1, and the disassembly part is located at the bottom of the outer shell 1. By rotating the rotating base 2, the outer shell 1 can be opened, allowing the filter element assembly 5 to be removed from the outer shell 1 for replacement, thus eliminating the need to disconnect the water pipe when replacing the filter element assembly 5. At the same time, to prevent the filter element assembly 5 from tilting or shifting during installation, conical blocks 3 are provided on the adjusting base plate 21 and the top of the outer shell 1. When the user rotates the rotating base 2 for installation, as the two conical blocks 3 are pulled closer, the filter element assembly 5 will be guided to move to the center position, thus eliminating the need for users to perform alignment and positioning operations, simplifying the installation difficulty and steps.

[0031] Normally, when the rotating base 2 is tightened, the top of the rotating base 2 and the outer shell 1 will connect and seal with the second sealing ring 51, forming two spaces inside and outside the filter element assembly 5. The water source on the outside is filtered when it passes through the filter element assembly 5, and the filtered water flows out from the inner space. However, if the second sealing ring 51 is damaged or the precision control of the filter element assembly 5 is not precise enough, the inner and outer spaces may be connected and leak due to incomplete sealing, which will cause secondary pollution of the filtered water. This device provides an adjustable base plate 21 on the rotating base 2 that can be finely adjusted, so that the adjustable base plate 21 can be adjusted again after the rotating base 2 is tightened, thereby ensuring the sealing after installation.

[0032] Example 2: Refer to Figures 1-7Similar to Embodiment 1, but with a further improvement: the top of the outer casing 1 is provided with an inlet pipe 12 and an outlet pipe 11, with the outlet pipe 11 located at the center of the top of the outer casing 1; an adjusting bolt 23 is rotatably connected to the adjusting base plate 21, and the adjusting bolt 23 is threaded to the adjusting base plate 21; a supporting side plate 22 is provided on the rotating base 2; a limiting rod 211 is connected to the adjusting base plate 21, and the limiting rod 211 is slidably connected to the rotating base 2; and sliding parts 4 are slidably connected to both the top of the outer casing 1 and the adjusting base plate 21. The sliding member 4 located on the adjusting base plate 21 passes through the rotating base 2. The sliding member 4 is equipped with a compression spring 43. A through hole 42 is opened in the sliding member 4. Water holes 41 are respectively provided at the top and bottom of the sliding member 4. The water holes 41 at the top and bottom are connected through the through hole 42. A first sealing ring 31 is provided on the conical block 3. When the filter element assembly 5 is installed, a sealed space is formed between the first sealing ring 31 and the second sealing ring 51. A support member 6 is provided at the top of both the adjusting base plate 21 and the outer shell 1. Multiple leakage holes 61 are opened on the support member 6.

[0033] In this invention, a first sealing ring 31 is provided on the conical block 3. After the filter element assembly 5 is installed, a narrow sealing space is formed between the first sealing ring 31 and the second sealing ring 51. If both the first sealing ring 31 and the second sealing ring 51 are properly sealed, there will be no water in this space, which is a cavity. If one side is not properly sealed, the cavity will be filled with water. At this time, the sliding member 4 will not overflow the water inside the cavity under the action of the compression spring 43. However, when the user presses the sliding member 4 to move, the water inside the cavity will flow out to the outside through the water hole 41 and the through hole 42. The user can use this method to judge whether the filter element assembly 5 is properly sealed after installation. At the same time, by setting the first sealing ring 31 and the second sealing ring 51, two sealing layers can be formed. Even if one side fails to seal, the water on both sides can still be prevented from leaking and causing pollution.

[0034] The support member 6 is connected to the outer shell 1 and the adjusting base plate 21 by multiple support columns, thereby providing lateral support for the first sealing ring 31 and the second sealing ring 51, preventing the first sealing ring 31 and the second sealing ring 51 from tilting due to water pressure and causing sealing failure. The support member 6 is provided with multiple leakage holes 61, so that when there is a leak, water can fill the entire cavity through the leakage holes 61.

[0035] The rotating base 2 is provided with a support side plate 22, which can provide space for the bottom support and prevent the adjusting bolt 23 and the sliding part 4 from contacting the ground and being disturbed. By rotating the adjusting bolt 23, the sliding part 4 can be moved up and down for adjustment. It should be noted that the direction of rotation of the adjusting bolt 23 to move the sliding part 4 upward is the same as the direction of tightening of the rotating base 2. The adjusting base plate 21 is provided with two limit rods 211, which are slidably connected to the rotating base 2, thereby limiting the adjustment base plate 21 and preventing the adjustment base plate 21 from rotating with the adjusting bolt 23.

[0036] The water outlet pipe 11 is located in the middle of the top of the outer shell 1 and is connected to the internal space of the filter element assembly 5. The water inlet pipe 12 is connected to the outer space of the filter element assembly 5. External water enters from the water inlet pipe 12 and is filtered by the filter element assembly 5 before entering the inner space and flowing out from the water outlet pipe 11.

[0037] When disassembling and installing the filter element assembly 5, the user first opens the rotating base 2 to remove the filter element assembly 5 that needs to be replaced from the outer shell 1, inserts the new filter element assembly 5 into the conical block 3 inside the outer shell 1, and then closes the rotating base 2. When closing the rotating base 2, the adjusting base plate 21 needs to be reset to the position in contact with the rotating base 2. After the rotating base 2 is installed, the base plate 21 is adjusted again for a second adjustment. After the adjustment is completed, the water source can be connected. At this time, the sealing condition after installation can be judged by pressing the top or bottom sliding piece 4 to see if water continues to flow.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
