This invention belongs to the field of HVAC technology and discloses an air purification device for HVAC systems, comprising: a chassis with an air outlet at the top; and a disassembly / assembly mechanism located inside the chassis. This invention achieves convenient disassembly and assembly of the filter screen through the design of the disassembly / assembly mechanism, improving the ease of device maintenance. Operators only need to pull the lever to release the overall fixation of the filter screen. Simultaneously, during the installation and resetting process, the elastic force of the first spring drives the insert block to automatically engage with the pre-reserved slot on the square rod, achieving rapid fixation of the filter screen. This effectively shortens the time required for filter screen cleaning or replacement, reduces the professional requirements for operators, and allows ordinary users to complete the operation independently. It significantly reduces the manpower and time costs associated with batch disassembly and assembly of filter screens, avoids component damage problems such as stripped bolts and broken clips in traditional disassembly / assembly methods, and improves equipment maintenance efficiency and service life.
