Document Type and Number:
WIPO Patent Application WO/2023/008421
Kind Code:
A1
Abstract:
Provided is an active oxygen supply device capable of more efficiently supplying active oxygen to the surface of an object to be treated. The active oxygen supply device comprises: a housing having at least one opening; an ozone generator placed within the housing; a means for generating an air flow that contains ozone generated inside the housing by the ozone generator, moves toward the opening and flows out of the housing through the opening; and an ultraviolet ray light source that is arranged so that the ozone-containing air flow flowing out of the housing through the opening can be irradiated with ultraviolet rays, wherein the ultraviolet ray light source decomposes the ozone in the air flow to generate active oxygen, and the air flow containing the active oxygen, that is generated by irradiating the ozone-containing airflow with the ultraviolet rays, is supplied to an object to be treated outside the housing.
