▎ 摘　　要

NOVELTY - The fan comprises a filtering cabin module sleeve whose one end is connected with the air pressure sleeve air inlet hole (635) on the main box clapboard (615). A clean gas passage (623) is arranged at the position corresponding to the clean gas conversion chamber (636) in the high clean gas filter cabin and the comprehensive cabin (630). The gas enters the comprehensive cabin air passage area (617) by the main machine suction gas inlet (616). The air pressure sleeve inlet hole from the middle of the main machine clapboard enters into the filter cabin module sleeve in the high clean gas filter cabin. The filtered high clean gas enters the high clean gas filter cabin gap, and then enters the clean gas conversion chamber of the comprehensive cabin of the main machine from the clean gas channel, through the gas guide connector. The air conveyed by air guide connector and air guide corridor is blown out through middle air outlet in the middle of air guide integrated plate. USE - High-clean multifunctional fresh air purifying fan for use in field of gas filtering and indoor air treatment. ADVANTAGE - The fan can perform high clean filtering and releasing negative oxygen ion to fine particulate matter. The filtered virus, bacteria and so on are collected in the high clean filter module, when changing, it does not pollute the environment. The fan has multi-character and multifunctional use characteristics. The mode conversion is convenient, fresh air improvement is convenient. It can be used for filtering to provide high ultra-clean gas, better satisfy the need of one machine for multiple uses. The melt-blown cloth has static adsorption filtering effect on the particulate matters. The nanometer film has blocking and filtering effect to the fine matter in the air according to the nano-particle aperture. The graphene active carbon has the function of absorbing and filtering the toxic gas.
