MASK
Document Type and Number:
Japanese Patent JP2021165452
Kind Code:
A
Abstract:
To solve the problem that, though a mask has a function of filtering viruses, miscellaneous bacteria, pollen, dust, and the like, and is essential for maintaining a human health, a conventional mask is not used preferably because inspired air and expired air are mixed in the mask, the mask moistens due to moisture in the expired air, the air permeability is degraded, the miscellaneous bacteria proliferates, and the inside of the mask becomes smelly and unpleasant, as well as though there is a method of deodorizing and sterilizing a diaper by blowing ozone into the diaper, an ozone generator cannot be used for deodorizing/sterilizing a mask because the ozone generator is large in size and is poor in portability.SOLUTION: A method for deodorizing and sterilizing a mask comprises disposing a space between the cloths of the mask in which a plurality of cloths is laminated, and supplying ozone to the space so that the space is uniformly filled with ozone. The space of the mask and an ozone generator are connected by a tube, and the ozone generated in the ozone generator is force-fed to the space by an air supply device. Since the inside of the mask is deodorized/sterilized by a deodorizing/sterilizing power of the ozone, and does not become smelly even if it is worn for a long time, a clean mask can be provided.SELECTED DRAWING: Figure 1
