Patent number: 10967207Abstract: The present invention relates to a respirator without breathing resistance, which has an air inlet duct that passes through an inside and an outside of the respirator and that has asymmetrical electrodes and particle capturing plates formed on an inner surface of the air inlet duct; ozone removing element that removes ozone generated by micro-plasma; and high voltage dc-dc converter that provides high voltage to the asymmetrical electrodes. It employs asymmetrical electrodes and particle capturing plates to filter air without generating breathing resistance. When the respirator according to the present invention is used, safety of a wearer may be maintained in accordance with an environment and breathing may be smoothly performed even while introduction of pathogenic bacteria, viruses, fungi, spores, fine dust, or the like included in air may be effectively blocked. Accordingly, the respirator may be widely utilized to maintain the safety of the wearer in various environments.Type: GrantFiled: November 17, 2016Date of Patent: April 6, 2021Assignees: Ewha University—Industry Collaboration Foundation, Korea University Research and Business FoundationInventors: Ah Jeong Son, Beelee Chua, Mi Ri Park, Min Kyoung Lee
