Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a medium-efficiency air filter for indoor air purification. Background Art

[0002] Medium-efficiency air filters are an important component of indoor air purification systems. Their main function is to filter tiny particles and pollutants in the air and improve indoor air quality. Medium-efficiency air filters can effectively capture particles with a diameter between 1 and 10 microns in the air, such as dust, pollen, and dust. They have a good filtering effect on tiny particles in the air and are usually used in commercial buildings, hospitals, laboratories, offices and other places that require high air quality. They can also be used in household air purification equipment.

[0003] In the prior art, most of the medium-efficiency air filters used will have a lot of filtered impurities in the internal filter medium during long-term operation, and they need to be cleaned regularly. When cleaning, the filter screen or filter plate needs to be disassembled. Since the filter screen and filter plate are installed inside the filter, the filter shell or the filter as a whole needs to be disassembled during disassembly to remove the filter screen or filter plate, which results in a cumbersome disassembly during cleaning. Utility Model Content

[0006] As an improvement of the above technical solution, limit frames are fixedly installed on both sides of the outer surface of the adsorption box, and limit strips are fixedly installed on both sides of the outer surface of the base box. The limit strips are inserted into the inside of the limit frames, and the lower ends of the limit strips are in contact with the outer surface of the base box.

[0007] As an improvement of the above technical solution, the filtering mechanism includes a square filter cover movably installed inside the filter box, and the interior of the square filter cover is fixedly installed with a first filter screen and a second filter screen in sequence from top to bottom, and the filter hole diameter of the first filter screen is larger than the filter hole diameter of the second filter screen.

[0008] As an improvement of the above technical solution, slots are opened on both sides of the interior of the filter box, and plug blocks are fixedly installed on both sides of the outer surface of the square filter cover. The plug blocks are movably inserted into the slots, and a handle is fixedly installed on the upper end of the plug blocks.

[0009] As an improvement of the above technical solution, a second magnet block is embedded in the bottom of the slot, a first magnet block is fixedly installed on the bottom of the insert block, and the positions of the first magnet block and the second magnet block correspond to each other.

[0010] Beneficial effects of the utility model:

[0011] 1. By movably installing an adsorption box on the upper end of the base box, and then movably installing a filter box above the adsorption box, an activated carbon plate is arranged in the adsorption box, and a filter mechanism is arranged inside the filter box. After the filter mechanism in the filter box and the activated carbon plate arranged in the adsorption box have worked for a long time, too many impurities will be accumulated inside. Since the adsorption box and the filter box are movably installed, the adsorption box and the filter box can be easily removed, and the activated carbon plate and the filter mechanism arranged inside the adsorption box and the filter box can be cleaned and cleared of debris, so that they can be used again, thereby increasing the convenience of cleaning the debris accumulated inside the device.

[0012] 2. An adsorption box and a filter box are sequentially arranged at the upper end of the base box, and a vortex fan is arranged inside the base box. Under the action of the vortex fan, external air enters from the top of the filter box, passes through the filter mechanism arranged inside the filter box, and the activated carbon plate installed inside the adsorption box in turn, and is finally sprayed out from the strip air outlet groove. The filter mechanism in the filter box can remove most of the debris in the air for the first filtration, and then the filtered air is filtered under the action of the activated carbon plate, which can absorb odors and tiny impurities in the air for secondary filtration, thereby efficiently purifying and filtering the air.
