Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air filter installation assembly. Background Technology

[0002] As people's quality of life continues to improve and their attention to health deepens, their requirements for air quality are also rising. Against this backdrop, air filters, with their excellent purification efficiency, have been widely used in various places such as homes, offices, hospitals, and schools.

[0003] In today's widely used air filter systems, the filter screen plays a crucial role in filtration. As the equipment continues to operate, dust in the air accumulates on the filter screen, eventually clogging its pores and significantly reducing filtration efficiency. To ensure that the air filter can consistently purify the air efficiently, regular filter screen replacement is an essential maintenance step. However, existing air filter installation components are generally fixed in place within the filter housing. When the filter screen needs replacement, maintenance personnel must remove the entire air filter assembly from the housing. The internal structure of the assembly is often complex, with each component tightly connected. The removal process requires careful handling, disassembling numerous connectors one by one. This undoubtedly increases the workload and time commitment, coupled with the risk of component damage due to improper operation, further increasing maintenance costs. This brings considerable inconvenience and financial burden to both users and maintenance personnel, failing to meet current needs. Utility Model Content
