Description

Technical Field

[0001] This utility model relates to the field of sterilizer filter technology, and in particular to a plasma air sterilizer filter that is easy to disassemble. Background Technology

[0002] Plasma air sterilizers are devices that use plasma technology to disinfect the air. By generating a plasma field, they destroy the biomolecular structure of microorganisms in the air, thereby rendering them inactive and achieving the purpose of disinfection and sterilization. They can also effectively remove odors, dust, and harmful gases from the air, thus purifying the air. They have the advantages of high disinfection efficiency, no secondary pollution, and no need for personnel to evacuate during operation. They are widely used in hospitals, schools, and offices to provide people with a healthy and safe air environment.

[0003] With technological advancements, modern plasma air sterilizer filters have seen significant improvements in filtration performance, capable of filtering even finer particles, bacteria, viruses, and harmful gases. While existing filters use clips and slots for fixation, in practice, the clips are often too tight, requiring considerable force for disassembly, which is difficult for users with limited strength. Excessive force can even cause the clips to break. Furthermore, after prolonged use, the filter slots are prone to jamming due to dust accumulation and component deformation, making it difficult to remove the filter smoothly. Some complex filter installation structures also make disassembly cumbersome, severely impacting user experience and limiting filter maintenance efficiency and the sterilizer's continuous, efficient operation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a plasma air sterilizer filter that is easy to disassemble, aiming to improve the problem that the disassembly of the filter structure in the prior art is not convenient enough, which affects the user experience.
