Title:
ACTIVE OXYGEN SUPPLY DEVICE, DEVICE FOR PERFORMING TREATMENT WITH ACTIVE OXYGEN, AND METHOD FOR PERFORMING TREATMENT WITH ACTIVE OXYGEN
Document Type and Number:
WIPO Patent Application WO/2023/127833
Kind Code:
A1
Abstract:
This active oxygen supply device is provided with a plasma actuator and an ozone decomposition device both arranged in a housing having at least one opening, in which the plasma actuator includes a first electrode, a dielectric body and a second electrode which are stacked in this order, the first electrode is an exposed electrode and blows out an ozone-containing induction flow in a first direction upon the application of a voltage between the electrodes, the ozone decomposition device decomposes the ozone contained in the induction flow to generate active oxygen in the induction flow, the induction flow is converted to an induction flow containing the active oxygen, the plasma actuator and the ozone decomposition device are arranged in such a manner that the induction flow containing the active oxygen can flow outside the housing through the opening, at least a portion of a first-direction-side edge part of the first electrode overlaps with the second electrode, the edge part of the first electrode has a notched part having a shape enabling the increase in the flow rate of the induction flow, and the ozone decomposition device is at least one device selected from the group consisting of an ultraviolet light source and a heating device.
