Description

Technical Field

[0001] This utility model relates to the field of air purification, specifically to a novel air purifier filter. Background Technology

[0002] Air purifiers, also known as "air cleaners," are products that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other indoor pollutants, bacteria, allergens, etc.), effectively improving air cleanliness. Air purifiers are used in residential, medical, and industrial fields. In the residential sector, single-unit household air purifiers are the mainstream product, primarily removing particulate matter from the air, including allergens and indoor PM2.5. They can also address indoor air pollution caused by renovations or other factors. Because the release of air pollutants in relatively enclosed spaces is persistent and unpredictable, using air purifiers to purify indoor air is an internationally recognized method for improving indoor air quality. The main component in adsorption-type air purifiers that performs the filtration function is the filter element. However, existing filter elements typically use multiple layers of filters, resulting in poor filtration efficiency. When the filter element becomes clogged, the entire unit needs to be replaced, as the internal components cannot be disassembled, cleaned, and reused, leading to significant resource waste. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a new type of air purifier filter element with good filtration effect, which can be disassembled, cleaned and reused to avoid waste of resources and reduce the cost of use.

[0004] To address the aforementioned technical problems, the present application employs the following technical solution: a novel air purifier filter element, comprising a filter cartridge, a filter element disposed at the front of the filter cartridge, and a honeycomb filter plate disposed at the rear of the filter cartridge. The front side of the filter cartridge is provided with a front retaining ring to block the filter element, and the rear side of the filter cartridge is provided with a rear retaining ring to block the honeycomb filter plate. The filter element has a retaining ring on its upper ring that engages with the front retaining ring. Dual filtration through the filter element and honeycomb filter plate results in excellent filtration performance. The front retaining ring, rear retaining ring, and retaining ring increase the sealing between components, ensuring the filtration effect of the filter element and honeycomb filter plate. The retaining ring connection facilitates disassembly and assembly, making replacement and cleaning convenient.

[0005] Preferably, the outer wall of the filter cartridge is provided with a sealing ring that engages with the front retaining ring. When assembled with the purifier, the outer wall of the filter cartridge and the purifier are sealed together by the sealing ring to prevent air from flowing out from the gap between them and affecting the filtration effect.

[0006] Preferably, the filter element adopts a folded structure, including a plurality of folded strips, and the filter element is provided with a plurality of positioning strips for positioning the folded strips. The folded structure can increase the filtration area, improve the filtration effect, and extend the service life of the filter element; the positioning strips are used to limit the folded strips, prevent adjacent folded strips from sticking together, and ensure the normal use of the filter element.

[0007] Preferably, the positioning strip has several positioning grooves, and the folds formed by adjacent folded strips engage with the positioning grooves. This provides good positioning and improves the filtration effect.

[0008] Preferably, the positioning strip is formed in one step using a shaping adhesive and a folding strip. This facilitates production and reduces production costs.

[0009] Preferably, the outer side of the filter element is provided with a filter cotton layer that contacts the front retaining ring. The filter cotton layer can filter out larger particles in the air, preventing large particles from clogging the filter element and improving its service life; the filter cotton layer is also easy to disassemble and clean, and even if it needs to be replaced, the cost is low.

[0010] Preferably, the honeycomb filter plate contains activated carbon filler, and the outer side of the honeycomb filter plate is provided with a filter screen that contacts the rear retaining ring. The activated carbon filler can improve the adsorption capacity, and the filter screen can prevent the activated carbon filler from leaking out, ensuring the cleanliness of the filtration channel.

[0011] Preferably, at least one pull bar is provided between the filter element and the retaining ring. This facilitates the removal of the filter element from the filter cartridge for replacement, improving the convenience of replacement.

[0012] Preferably, two pull strips are used, evenly arranged around the retaining ring. Using two pull strips simultaneously ensures even force distribution and avoids damaging the filter element and retaining ring.

[0013] Preferably, the filter cartridge, front retaining ring, and rear retaining ring are integrally injection molded structures. This facilitates manufacturing, reduces manufacturing costs, and increases strength.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] A novel air purifier filter element employing the above technical solution achieves dual filtration through the filter element and honeycomb filter plate, resulting in excellent filtration performance. The front retaining ring, rear retaining ring, and retaining ring enhance the sealing between components, ensuring the filtration effect of the filter element and honeycomb filter plate. The connection method using retaining rings facilitates disassembly and assembly, making it easy to replace, clean, and reuse, avoiding resource waste and reducing operating costs.
