Description

Technical Field

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

[0002] The plate activated carbon filter is actually a frame with an activated carbon filter installed inside. The activated carbon filter uses aluminum honeycomb, plastic honeycomb, and paper honeycomb with a through-hole structure as a carrier. Compared with traditional activated carbon filters, it has better gas dynamics, small volume density, large specific surface area, high adsorption efficiency, and small wind resistance coefficient. The honeycomb activated carbon filter is made of powdered activated carbon attached to polyurethane foam. It has the efficient adsorption performance of activated carbon and can be used for air purification, removing volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene and pollutants in the air. It has low air resistance and low energy consumption. It can deodorize and remove odors at a certain air volume to purify the environment with a good purification effect.

[0003] After a period of use, in order to ensure the internal activated carbon filter material's air treatment effect and filtering ability, the internal filter material needs to be replaced. When replacing the filter material, the plate-type activated carbon filter of the prior art needs to disassemble the filter shell as a whole, which includes the disassembly of a large number of bolts and the adjustment of various fasteners. This makes the overall replacement process of the plate-type activated carbon filter material slower, resulting in poor practicality and convenience. Based on this, an activated carbon plate filter that is easy to replace is proposed. Utility Model Content

[0027] See also Figure 1-4 The utility model provides a technical solution: an activated carbon plate filter that is easy to replace, including a mounting frame 1, a first connecting structure 4 and a second connecting structure 6. A filter element 2 is arranged inside the mounting frame 1. It should be noted that the filter element 2 is an activated carbon filter element. This part is an existing use technology and will not be elaborated here.

[0028] The outer walls of both sides of the filter element 2 are fixedly installed with mounting seats 3, and the mounting seats 3 and the inner walls of the mounting frame 1 are fitted together. The first connecting structure 4 is located on the mounting frame 1. The first connecting structure 4 is four groups and corresponds to the mounting seats 3 one by one. The first connecting structure 4 includes a shell 401, a tension spring 402, a connecting block 403, a clamping column 404, a connecting rod 405 and a handle 406. The outer walls of both sides of the mounting frame 1 are fixedly installed with shells 401, a tension spring 402 is fixedly installed on the inner wall of one side of the shell 401, and a connecting block 403 is slidably installed inside the shell 401. The free end of the tension spring 402 is fixedly connected to the outer wall of one side of the connecting block 403, and the outer wall of the other side of the connecting block 403 is fixedly installed with a clamping column 404. A card slot matching the clamping column 404 is opened on the mounting seat 3, and the card slot and the clamping column 404 are configured for a card connection. This part can realize the installation and positioning of the filter element 2.

[0029] A connecting rod 405 is fixedly installed on the outer wall of one side of the connecting block 403, and a handle 406 is provided on one side of the shell 401. The connecting rod 405 passes through the shell 401 and is fixedly connected to the handle 406. When the handle 406 is pulled, the handle 406 drives the connecting rod 405 to move horizontally. When the connecting rod 405 moves horizontally, the tension spring 402 is compressed. The compression of the spring 402 causes the connecting block 403 to move horizontally, so that the clamping column 404 is disengaged from the clamping slot, the positioning of the filter element 2 is cancelled, and the filter element 2 is taken out. The structure is easy to load and unload, simple to operate, and has improved practicality and convenience, and is easy to promote.

[0030] A cover plate 5 is placed on the mounting frame 1, and the mounting frame 1 positions the cover plate 5 through a second connecting structure 6. The second connecting structure 6 includes a connecting seat 601, a compression spring 602, a slider 603, a first positioning plate 604, and a second positioning plate 605. The outer walls of both sides of the mounting frame 1 are fixedly installed with connecting seats 601, a compression spring 602 is fixedly installed on one side outer wall of the connecting seat 601, a slider 603 is slidably installed inside the connecting seat 601, a free end of the compression spring 602 is fixedly connected to the slider 603, a first positioning plate 604 is fixedly installed on the top of the slider 603, and a second positioning plate 605 is fixedly installed on one side outer wall of the first positioning plate 604. The slider 603 is pulled and squeezed by the slider 603 to squeeze the compression spring 602, so that the first positioning plate 604 and the second positioning plate 605 cancel the positioning of the cover plate 5, and the cover plate 5 is taken out. This structure can realize the positioning of the cover plate 5 and ensure the protection of the filter element 2 by the cover plate 5.

[0031] A protrusion is fixedly installed on the front side of the slider 603, and the slider 603 can be operated conveniently by using the protrusion.

[0032] Working principle: When the filter element 2 needs to be replaced during use, first pull the slider 603, and the slider 603 squeezes the compression spring 602, so that the first positioning plate 604 and the second positioning plate 605 cancel the positioning of the cover plate 5, and the cover plate 5 is taken out. This structure can realize the positioning of the cover plate 5, and ensure the protection of the filter element 2 by the cover plate 5;

[0033] Next, pull the handle 406, which drives the connecting rod 405 to move horizontally. When the connecting rod 405 moves horizontally, the tension spring 402 is compressed, and the compression of the spring 402 causes the connecting block 403 to move horizontally, thereby causing the clamping column 404 to disengage from the clamping slot, canceling the positioning of the filter element 2, and thus taking out and replacing the filter element 2. This structure is easy to load and unload, simple to operate, and has improved practicality and convenience, making it easy to promote.
