Portable intake air sterilizing apparatus

A portable intake air sterilizing apparatus, comprising:

• a cover member for covering one or both of a nose and a mouth;
• an air intake portion for an inner space of the cover member;
• and
• a chlorine dioxide slow-release portion capable of releasing chlorine dioxide gas into an intake air in association with introduction of this intake air from the air intake portion, wherein
• the air intake portion is communicated and connected to an end of a flexible tube whose other end is communicated and connected to the cover member, and in the air intake portion, there is formed the chlorine dioxide slow-release portion comprising an electrolysis device for generating an amount of chlorine dioxide through an electrolysis,
• the electrolysis device includes an electrolysis bath holding therein an amount of electrolysis solution containing alkaline chloride, alkaline chlorite and a pH adjustor, a pair of electrodes submerged into the electrolysis solution held in the electrolysis bath, and a power supply unit for supplying electric current to the electrodes,
• an aeration device configured to aerate the electrolysis solution held in the electrolysis bath, and
• the aeration device comprises an intake air blowing flexible tube having its one end inserted into the electrolysis solution and having its other end connected to the cover member.
