Description

Technical Field

[0001] This utility model relates to the field of fresh air system related products, specifically a fresh air system all-effect purification box. Background Technology

[0002] The fresh air purification box is installed at the air inlet and used in conjunction with a total heat exchanger and a two-way flow fresh air unit to effectively filter harmful substances in outdoor air. The purification box has a dual filtration function: a coarse filter and a fine filter. The coarse filter removes dust, compounds, and other harmful substances visible to the naked eye, while the fine filter removes carbon monoxide, carbon dioxide, formaldehyde, benzene, vehicle exhaust, factory emissions, and other harmful gases invisible to the naked eye. Air pollution is severe and poses significant health risks. The air contains a large amount of fine particulate matter, which is small in size, large in surface area, and highly mobile, easily carrying toxic and harmful substances. Therefore, the use of purification boxes effectively improves air cleanliness and is currently widely used in residential, commercial, industrial, and building environments.

[0003] The existing patent "CN202221397252.9" proposes a multi-functional smart screen device integrated fresh air purification box, including: a box body, which is constructed to form an air inlet and an air outlet at both ends along the length direction; two partitions are disposed in the box body to make the box body form three modular spaces; the multi-functional smart screen device integrated fresh air purification box further includes: defining the three modular spaces as a dust removal space, a fan space and a disinfection space, so that the dust removal space, the fan space and the disinfection space are arranged sequentially along the airflow direction.

[0004] The existing air purifier's fan consists of a motor and an impeller. The components are fixed to the mounting plate with screws. When the fan needs to be repaired or replaced, the entire air purifier needs to be removed from the ceiling and the entire air purifier removed before repair, which is quite cumbersome. In addition, the filter material fixing structure is quite complex, and it is troublesome to disassemble and install it back and forth. Utility Model Content

[0005] The purpose of this invention is to provide a comprehensive air purification box for a fresh air system to solve the problems mentioned in the background art.
