Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air purification filter element. Background Technology

[0002] In today's society, with people paying increasing attention to air quality, air purifier filters, as a key component of air purification equipment, play a vital role. The main function of air purifier filters is to filter pollutants such as particulate matter, harmful gases, and microorganisms from the air, creating a healthy and fresh breathing environment for people.

[0003] Air purifier filters typically consist of multiple components. The frame is a crucial part of the filter, serving to support and secure the filter layers. However, most existing air purifier filter frames are made of metal or plastic. While metal frames offer high strength and stability, they also have some significant drawbacks. Firstly, metal is relatively heavy, increasing the overall weight of the air purifier filter. This not only increases the difficulty of transportation and installation but may also lead to higher energy consumption for the air purifier. Secondly, metal frames are prone to corrosion in humid or corrosive environments, affecting the filter's performance and lifespan. Furthermore, the metal ions produced by corrosion may be released into the air, causing secondary air pollution.

[0004] While plastic frames reduce weight, some plastic materials may release volatile organic compounds during production, which can negatively impact air quality and contradict the original purpose of air purification filters.

[0005] Given the problems with existing air purification filter frames, there is an urgent need for a new, more environmentally friendly, lightweight, and stable frame material to replace traditional metal or plastic materials in order to improve the overall performance and quality of air purification filters.

Its unfolded state features a multi-segment folding design, forming a stable cuboid base (first base 112 and second base 122) and side structures (first side 111 and second side 121). Combined with a beveled joint design (such as the beveled fit between the first cover plate 113 and the second cover plate 123), this ensures that the assembled frame 1 has sufficient support strength and sealing. The filter layer 2 is fixed to the cavity of the frame 1 with adhesive. Its wavy or serrated structure increases the filtration area, effectively intercepting particulate matter and pollutants in the air.
