Description

Technical Field

[0001] The invention relates to the field of filter element consumables, and in particular to a paper frame foldable evenly spaced consumable filter screen and a transportation method. Background Art

[0002] With the significant improvement of social living standards and people's increasing requirements for air quality, various air purifiers and fresh air systems have become important electrical equipment for achieving indoor air purification. In these air purification devices, the filter plays a vital role, and it is an indispensable key component for achieving air purification function.

[0003] However, as a consumable, the filter has a limited service life, so it needs to be replaced regularly to ensure the continuity and effectiveness of the air purification effect.

[0004] In fact, the filter replacement cycle is determined according to its usage and environmental conditions, but generally speaking, in order to keep the air purifier in the best working condition, the filter needs to be replaced regularly.

[0005] Therefore, when considering the installation and transportation of air purification equipment, the design and material selection of its rigid shell will bring additional cost burden, which to some extent affects the overall cost-effectiveness.

[0006] Regarding the limitations of existing technical solutions, we have the following observations: First, due to its non-foldable nature, the traditional filter screen is large in size, which not only increases the difficulty of logistics and transportation, but also increases the transportation cost accordingly. Especially when it comes to international foreign trade business, the cost problem is particularly prominent due to the increase in transportation distance. Secondly, the traditional filter screen is often designed with a plastic frame or a metal frame. Although such a design can provide a certain structural strength, it also brings higher manufacturing costs.

[0007] On April 8, 2025, a search was conducted in the Chinese Patent Publication Database using "paper and filter element and fold and distance" as abstract keywords, with the option to allow synonym expansion, and the following documents were found: CN102990694A Pleated paper offline slitting machine for corrugated filters; this document is a production device and has nothing to do with this patent.
