AIR STERILIZATION/PURIFICATION DEVICE, AND EXHALED-AIR STERILIZATION/PURIFICATION DEVICE, INDOOR AIR STERILIZATION/PURIFICATION DEVICE, AND SIMPLIFIED ISOLATION DEVICE USING SAID AIR STERILIZATION/PURIFICATION DEVICE

摘要

Disclosed is an air sterilization/purification device provided with: a cylindrical reflector (10) which has a mirrorized inner surface, inside which air flows from a top end to a bottom end; a rod-shaped ultraviolet lamp (12) disposed in the middle of the cylindrical reflector (10) along the long direction thereof; air-permeable plate-shaped photocatalytic filters (14) that have diameters roughly equal to the inside diameter of the cylindrical reflector (10) and are inside the cylindrical reflector (10) at both ends thereof such that the ultraviolet lamp (12) goes through the middle of said filters; and an air-permeable plate-shaped photocatalytic filter (15) that has a diameter roughly equal to the inside diameter of the cylindrical reflector (10) and closes the bottom opening thereof.
