When replacing the filter in an existing air purifier, the old filter is easily disassembled, causing accumulated dust to fall out, increasing the cleaning burden on users and affecting the user experience.
The design features a detachable frame and shielding components. The frame can be quickly installed or removed using a knob, insert rod, and pull rope. Combined with belt drive and folding baffles for unfolding/folding, dust is prevented from scattering. The filter cartridge can be quickly fixed and unlocked using a fixing ring and chuck.
It simplifies the filter replacement process, reduces dust scattering, improves the convenience and safety of operation, and expands the applicable scenarios of the air purifier.
