Description

Technical Field

[0001] This utility model relates to the technical field of air filtration structures, specifically an air filtration structure for a vacuum cleaner. Background Technology

[0002] The air filtration system in a vacuum cleaner is a key component that ensures the performance of the vacuum cleaner and extends its service life. The vacuum cleaner uses an internal motor to drive a fan to rotate at high speed, generating negative pressure, which draws in air and dust. The drawn-in air and dust enter the filtration system inside the vacuum cleaner through the suction tube. The filtration system separates the dust and impurities in the air, and the clean air is discharged through the air outlet.

[0003] Common air filtration structures for vacuum cleaners typically use only a single filter element, resulting in a relatively simple structure and poor filtration performance. This may not be able to effectively filter particles of different sizes, especially fine dust and allergens, leaving airborne particles still present and affecting indoor air quality, thus causing some adverse effects on users. Therefore, we propose an air filtration structure for vacuum cleaners. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides an air filter structure for vacuum cleaners, offering advantages such as improved filtration efficiency and enhanced air quality. An anti-detachment positioning block is inserted into the inner side of the through-hole. An anti-slip flexible pad on the outer wall of the anti-detachment positioning block strengthens friction and enhances fastness. A connecting block is positioned at the lower end of the inner positioning ring block via a triangular positioning block, positioning the fixing ring block at the upper end of the inner positioning ring block. The filter bag filters larger particles. The nanofiber filter core, porous ceramic filter core, and activated carbon composite filter core are all positioned inside the filter control cylinder via the connecting ring block. Through multi-layer filtration, particles of different sizes can be intercepted, effectively filtering everything from large dust particles to tiny bacteria and viruses, thereby improving overall filtration efficiency. Simultaneously, it ensures cleaner exhaust air, reduces secondary pollution, and improves indoor air quality, effectively solving the problems in the background technology.

Both ends of the connecting block 10 are fixedly connected with triangular positioning blocks 11. When the anti-slip positioning block 8 is inserted into the inner side of the through anti-slip hole 4, the triangular positioning block 11 can play the role of anti-slip limiting at the lower end of the inner positioning ring block 3.

[0025] Furthermore, the fixing ring 6 and the filter bag 7 are integrally formed, and the upper end of the anti-detachment positioning block 8 is fixedly connected to the lower end of the fixing ring 6 around the perimeter to enhance the firmness.
