Description

Mask sterilizer {STERILIZATING APPARATUS FOR MASK}

The present invention relates to a mask sterilizing apparatus, and more particularly, to a mask sterilizing apparatus using a light source.

Since a mask is worn on a person's oral area, it is a good environment for bacteria to grow due to droplets and moisture in the mouth. In terms of the performance of the mask, it is possible to reuse several times, but it is true that it is reluctant due to bacterial growth. A mask sterilizer is a product that sterilizes a used mask so that it can be reused hygienically.

Mask sterilization methods include physical sterilization using high temperature and chemical sterilization using sterilizing agents. However, the above methods may cause damage to the mask, and when a sterilizing agent is used, there is a problem that may cause serious problems in the user's respiratory tract due to the sterilizing agent remaining in the mask after sterilization is performed.
