Description

Technical Field

[0001] The utility model belongs to the technical field of filters, in particular to a cartridge activated carbon filter which is easy to replace. Background Art

[0002] The cartridge activated carbon filter is a device that uses activated carbon for adsorption and filtration. Activated carbon has very fine pores and strong adsorption capacity. It has a large surface area and can fully contact with gas or liquid and be adsorbed by capillaries. Therefore, the cartridge activated carbon filter can effectively remove free matter, microorganisms, and some heavy metal ions in water, reduce the color of water, and remove odors, formaldehyde, benzene, ammonia and other harmful gases in the air;

[0003] At present, when the existing activated carbon filters are used, the activated carbon particles often adsorb a large amount of impurities over time, resulting in a decrease in filtering performance and being unable to maintain a stable filtering function;

[0004] In order to solve the above problems, the present application proposes a cartridge activated carbon filter that is easy to replace. Utility Model Content

[0005] The purpose of the utility model is to provide a cartridge activated carbon filter which is easy to replace, and solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a cartridge activated carbon filter which is easy to replace, comprising: a filter cartridge and a top cover installed on the upper end thereof; a filter element which is easy to replace is arranged inside the filter cartridge, a fixing seat for installing the filter element is arranged at the lower end of the top cover, a screw-on frame for reinforcing the connection is arranged on the outer side of the fixing seat; a jacket is arranged on the bottom of the filter element, a scraper for cleaning the inner wall of the filter cartridge is arranged on the outer side of the jacket, and a filter plate is arranged between the jacket and the scraper.

[0008] Furthermore, a hook plate for hooking the upper end of the filter element is provided at the bottom of the fixing seat, and an outer side of the fixing seat is provided with an external protruding tooth.

[0009] Furthermore, a rubber strip for resisting against the filter element to form a seal is arranged on the inner side of the jacket, and the outer side of the jacket is connected and fixed to the scraper through a connecting rod.

[0010] Furthermore, a side groove for storing impurities is provided on the inner side of the bottom of the scraper.

[0011] Furthermore, a spiral structure is provided on the inner side of the upper end of the screw-on frame to form a spiral connection with the outer protruding teeth.

[0012] Furthermore, a compression pad for compressing the hook plate is arranged on the inner side of the lower end of the screw-on frame.

[0013] Furthermore, the inner side of the fixing seat clamps the inner side of the filter element to form a seal and is connected to the water inlet of the top cover.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can directly clamp the upper end of the top cover by adding a fixing seat, and then screw the screw-on frame to combine it with the filter element. After this arrangement, when the performance of the activated carbon decreases and needs to be replaced, the top cover can be directly taken out, and the replacement can be completed quickly without complicated operations, which improves work efficiency and is convenient for maintenance and replacement.

[0016] The utility model arranges the jacket on the outer side of the bottom of the top cover, and when the top cover is removed, the scraper can be used to scrape the inner wall surface of the filter cartridge, so that the remaining impurities are scraped off and stored in the side groove. Compared with the existing installation and disassembly method, the inner wall of the cartridge can be cleaned at the same time of replacement, which is conducive to maintaining its long-term use effect and preventing the remaining impurities from affecting the water quality.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-5 As shown, the utility model is a cartridge activated carbon filter that is easy to replace, comprising: a filter cartridge 1 and a top cover 2 installed on the upper end thereof;

[0029] The filter cartridge 1 is provided with a filter element 3 for easy replacement inside, the lower end of the top cover 2 is provided with a fixing seat 4 for installing the filter element 3, and the outer side of the fixing seat 4 is provided with a screw-on frame 5 for strengthening the connection;

[0030] The bottom of the filter element 3 is provided with a jacket 6 , the outer side of the jacket 6 is provided with a scraper 7 for cleaning the inner wall of the filter cartridge 1 , and a filter plate 8 is provided between the jacket 6 and the scraper 7 .

[0031] Through the above scheme, the filter element 3 and the top cover 2 are combined into an integrated structure, so that during the installation and disassembly operations, the top cover 2 can be operated separately, thereby forming the effect of simultaneous installation; secondly, when the activated carbon adsorbs too many impurities, or when some impurities cannot be adsorbed by the activated carbon, they will remain on the inner wall surface of the filter cartridge 1, and then the installed scraper 7 can be used to scrape off the residual impurities on the inner wall of the filter cartridge 1 to maintain a long-term stable filtering effect.

[0032] Among them, a hook plate 9 for hooking the upper end of the filter element 3 is arranged at the bottom of the fixing seat 4, and an external convex tooth 13 is arranged on the outer side of the fixing seat 4. The hook plate 9 is an elastic rubber mechanism, and the upper end of the filter element 3 can be directly inserted into the interior. The operation is simple and the difficulty of assembly is reduced.

[0033] The inner side of the jacket 6 is provided with a rubber strip 10 for resisting against the filter element 3 to form a seal, and the outer side of the jacket 6 is connected and fixed to the scraper 7 through a connecting rod 12. The rubber strip 10 is also used to clamp the filter element 3 to form a fixing effect.

[0034] A side groove 11 for storing impurities is provided on the inner side of the bottom of the scraper 7 so that the scraped impurities can be directly taken out.

[0035] The inner side of the upper end of the screw-on frame 5 is provided with a spiral structure to form a spiral connection with the outer protruding teeth 13 .

[0036] A pressing pad 14 for pressing the hook plate 9 is arranged on the inner side of the lower end of the screw-on frame 5 to prevent the hook plate 9 from loosening.

[0037] The inner side of the fixing seat 4 clamps the inner side of the filter element 3 to form a seal and is connected to the water inlet of the top cover 2 .

[0038] It can be understood that the utility model can conveniently combine the filter element 3 and the top cover 2 into one body, which is convenient for assembly and disassembly operations to improve work efficiency. At the same time, the inner wall of the filter cartridge 1 can be automatically cleaned 1 during the disassembly process to maintain subsequent performance.

[0039] A specific application of the operation process of this embodiment is as follows: first, the upper end of the top cover 3 is inserted into the interior of the hook plate 9, and then the screw-on frame 5 is screwed onto the outer side of the fixing seat 4, which can drive the squeezing pad 14 to squeeze the hook plate 9, thereby tightening the upper end of the top cover 3 to form a clamping limit, and at the same time make the inner side of the upper end of the top cover 3 dock with the water inlet of the filter element 2. After this arrangement, the top cover 3 and the filter element 2 can be combined into one, which is convenient for assembly, disassembly, replacement and other processing; further, by inserting the bottom of the top cover 3 into the interior of the jacket 6, a rubber strip 10 is used to form a clamping limit thereon, and then when the top cover 3 is taken out, the scraper 7 can be used to directly scrape the inner wall of the filter cartridge 1 to remove the residual impurities on its surface, and the cleaning process is automatically completed during the disassembly process.
