Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a filtration device. Background Technology

[0002] Currently, with the increasing severity of environmental pollution and air quality issues, air purifiers have become essential devices for improving indoor air quality and are being increasingly widely installed in various indoor environments. The filter element inside the air purifier is its core component, and its performance directly affects the purification effect and operating costs. Existing technologies, such as the existing Chinese authorized patent CN220892476U, commonly used air purifier filters typically employ a multi-layer filtration structure, generally combining activated carbon filter layers and high-efficiency particulate matter to effectively remove particulate matter of different sizes, odors, and harmful gases from the air.

[0003] However, existing multi-layer filtration devices are inconvenient to maintain, especially since they are generally installed by stacking or nesting layers, making it difficult to replace or clean the filter components of a single layer. Often, the entire filtration device needs to be disassembled, which is cumbersome, time-consuming, and labor-intensive. Furthermore, there is still room for improvement in terms of installation stability and sealing after installation. Utility Model Content
