Description

Technical Field

[0001] This utility model relates to the field of filter carbon cartridge technology, and in particular to an assembled carbon cartridge for filters. Background Technology

[0002] Prefabricated activated carbon cartridge filters are devices used to purify air or water. Their main working principle is to use the adsorption properties of activated carbon to remove impurities, odors, and harmful chemicals from gases or liquids. Activated carbon has a huge specific surface area and porous structure, which can effectively adsorb various pollutants. In the filter, activated carbon is usually filled in a specific carrier, such as aluminum honeycomb, plastic honeycomb, or paper honeycomb structure, forming a plate-shaped or sheet-shaped filter medium, which is quite common in daily life.

[0003] Existing technologies, such as the utility model patent with publication number CN220360914U, disclose an easily disassembled carbon cartridge filter. This patent includes a filter element, and connecting plates one and two are attached to the outer surface of the filter element. When connecting plates one and two are installed on the outer surface of the filter element, the square grooves opened inside connecting plates one and two allow the connected tension springs to open and close the connecting plates one and two. At this time, different diameters of the filter element can be adjusted. The tension force of the tension springs can make the connecting plates one and two fit tightly against the outer surface of the filter element. Then, turning the knob will cause the rubber block connected to the end of the knob to push the filter element inside the connected plates one and two in a rotating motion, which facilitates the installation and disassembly of the upper end of the filter element. This allows the activated carbon inside the filter element to be emptied and replaced without frequently removing the top cover.

[0004] In daily use, it has been found that during the operation of filters, since a typical filter consists of an outer carbon cartridge and an inner carbon cartridge, the activity of the carbon cartridge in the filter deteriorates after prolonged use. At this point, it will be necessary to replace the carbon cartridge. However, the current method of replacing the carbon cartridge involves using a hammering tool to knock it off, which makes it inconvenient to replace and reassemble the carbon cartridge. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where, during the operation and use of filters, since a typical filter includes an outer carbon cartridge and an inner carbon cartridge, the activity of the carbon cartridge in the filter deteriorates after long-term use, and there will be a need to replace the carbon cartridge. However, in the existing technology, when replacing the carbon cartridge, a hammering tool is used to knock the carbon cartridge off, which makes it inconvenient to replace and assemble the carbon cartridge.

[0006] To solve the above technical problems, this utility model provides an assembled carbon cartridge for a filter, comprising: an outer cylinder and an inner cylinder, wherein the inner cylinder is located inside the outer cylinder; the lower surfaces of the outer cylinder and the inner cylinder are fitted with the same bottom cover; the upper ends of the outer cylinder and the inner cylinder are fitted with top covers; mounting mechanisms are provided on the end surfaces of the outer cylinder and the inner cylinder corresponding to the positions of the top cover and the bottom cover, respectively; the mounting mechanism includes a mounting ring; the inner wall of the mounting ring is fixedly connected to the upper arc surface of the outer cylinder; a plurality of fixing brackets are fixedly connected to the arc surface of the mounting ring; and the inner walls of the fixing brackets are rotatably connected to rotating...

The arc surface of the outer cylinder has a connecting hole corresponding to the position of the positioning rod. The inner wall of the connecting hole is threadedly connected to the arc surface of the positioning rod.

[0007] The effect achieved by the above components is as follows: when using the carbon cartridge in the filter, the inner cartridge is usually placed inside the outer cartridge. In order to facilitate the assembly and fixation of the carbon cartridge, the installation limit operation is performed by the installation mechanism set between the two ends of the outer cartridge and the inner cartridge and between the top cover and the bottom cover.

[0008] Preferably, the inner wall of the fixing frame is fitted with coil springs at both ends, and the two ends of the coil springs are fixedly connected to the rotating rod and the fixing frame, respectively.

[0009] The effect achieved by the above components is that the torsional force generated by the coil spring can limit the position of the rotating rod, which helps to better limit the operation.

[0010] Preferably, a fixing sleeve is fixedly connected to the arc surface of the rotating rod, and the fixing sleeve is a rubber sleeve.

[0011] The effect achieved by the above components is that the rubber fixing sleeve can abut against the inner wall of the fixing block, avoiding excessive compression and wear between the rotating rod and the fixing block.

[0012] Preferably, a sealing ring is fixedly connected to the inner wall of the top cover, and a plurality of extrusion shafts are threaded through the upper surface of the top cover. The arc surface of the extrusion shaft slides through the inner wall of the sealing ring, and the bottom end of the extrusion shaft abuts against the upper surface of the outer cylinder.

[0013] The effect achieved by the above components is that when the top cover is closed and fixed with the outer and inner cylinders, the sealing ring on the inner wall of the top cover can be used for protection, and the extrusion shaft that runs through the surface of the top cover can be rotated for better extrusion and limiting.

[0014] Preferably, a plurality of support blocks are fixedly connected to the inner wall surface of the bottom cover, and a plurality of support grooves are provided on the lower surface of the inner cylinder, with the inner wall of the support grooves interlocking with the surface of the support blocks.

[0015] The effect achieved by the above components is that, with the help of the insertion and limiting between the support block and the support groove, the position of the inner cylinder can be better protected.

[0016] Preferably, a limiting block is fixedly connected to the bottom of the inner wall of the bottom cover. The limiting block has a cross-shaped cross section. A limiting groove is formed on the lower surface of the inner cylinder. The inner wall of the limiting groove is inserted into the surface of the limiting block.

[0017] The effect achieved by the above components is to prevent the inner cylinder from shaking and being damaged inside the outer cylinder by using the cross-shaped limiting block and the limiting groove for insertion.

[0018] Preferably, the surface of the positioning rod is provided with an auxiliary groove, and the cross-section of the auxiliary groove is triangular.

[0019] The effect achieved by the above-mentioned components is that when threading the positioning rod, the auxiliary groove with a triangular cross-section can be used for anti-theft operation.

At the same time, the top and bottom covers are installed and closed to the outer and inner cartridges, preventing the inner cartridge from shaking or shifting inside the outer cartridge when the outer and inner cartridges are in use. This helps to better protect the outer and inner cartridges during installation. Attached Figure Description
