[0002] In laboratory environments, portable air circulation and purification equipment is a key device for ensuring the cleanliness and safety of the experimental environment. The insect prevention function at its air inlet is particularly important. Traditional laboratory air purification equipment often uses a barrier filter (metal filter, nylon mesh) with a structure that is fixed by multiple screws.

[0003] However, the screw fixing method requires turning multiple screws one by one to complete the disassembly and installation of the filter section. The operation is time-consuming and relies on tools (screwdrivers). Especially in high-frequency maintenance scenarios (biological laboratories, chemical laboratories with high dust concentrations), the multiple screw disassembly and assembly operations extend the overall maintenance time.

[0004] Therefore, how to quickly disassemble and assemble the insect-proof component at the air inlet of a laboratory air purification device has become a technical problem that urgently needs to be solved in this field. Summary of the Invention
