摘要
Observational evidence suggests that mask-wearing mitigates transmission of COVID-19;at the same time high respiratory resistance leads to an unwillingness to wear masks.This paper proposed a respiratory drive structure to reduce the air resistance of a mask.This structure provides different shapes during expiration and inspiration while focusing on filtering dust,bacteria,or viruses.Meanwhile,the assembled system on the mask can be disassembled and replaced.Then porous media simulation is used to verify the model effect.Experimental results of a new mask show that the ventilation resistance is reduced by 20%,and the bacterial filtration efficiency meets the requirements of YY 0469–2011.
