Active oxygen supply apparatus

An active oxygen supply apparatus comprising:

• a casing;
• a plurality of plasma generating devices provided in an inside of the casing and configured to generate an induced flow containing ozone;
• an ultraviolet light source provided in the inside of the casing and configured to irradiate the induced flow containing the ozone with ultraviolet light;
• a shielding plate provided in the inside of the casing and configured to shield the ultraviolet light irradiated from passing to an outside of the casing through an opening portion of the casing;
• and
• a shutter configured to be switched between a closed position and an opened position,
• wherein an active oxygen generated by irradiating the induced flow containing the ozone with the ultraviolet light from the ultraviolet light source is supplied to the outside of the casing through the opening portion of the casing, and
• wherein the opening portion becomes a closed state when the shutter is in the closed position and the opening portion becomes an exposed state when the shutter is in the opened position.
