AIR PURIFYING MASK CAPABLE OF FILTERING INHALED BREATH AND EXHALED BREATH

摘要

The present invention relates to an air purifying mask having a function of purifying exhaled air and, more particularly, the present invention enables a respiratory disease infection caused by the breathing of a carrier or suspected patient to be prevented in advance, by not only filtering and purifying air when inhaling outside air into the mask, but also filtering and purifying various germs and fine impurities included in exhaled breath when discharging the exhaled breath. Also, the present invention enables the exhaled breath of the carrier or suspected patient to be prevented from leaking out of an air inhalation unit, by providing the air inhalation unit, through which the outside air enters the mask, such that during inhalation the air inhalation unit is opened and during exhalation the air inhalation unit is closed, wherein a gap that can be formed in the air inhalation unit during exhalation is completely blocked. Therefore, the air purifying mask has an effect in that the exhaled air of the carrier or suspected patient can be prevented from leaking out of the air inhalation unit where filtering of the exhaled breath is impossible. In addition, the exhaled breath, which may be concentrated to a specific portion of a filter unit during exhalation, is diffused while being discharged, and thus the exhaled breath can be efficiently filtered and purified.
