The air sterilization-and-disinfection module can be adapted to an air conditioning conduit. The air sterilization-and-disinfection module includes multiple corrugated boards101disposed in the middle and inside a module body1, multiple wavy channels102disposed in between the multiple corrugated boards101, a plurality of grooves103and UVC-LED light boards104mounted in the module via the multiple wavy channels102, at least two metal meshes disposed at both top and bottom of the corrugated boards101, one or more photocatalytic meshes3on the surfaces of the metal meshes2, and a sterilization component that is disposed inside the wavy channels102for sterilizing the air conditioning conduit.

Further, the sterilization component includes a plurality of UVC-LED light boards104disposed inside the wavy channels102, a reflective layer105formed on inner surfaces of the wavy channels102and outside the UVC-LED light boards104, and one or more photocatalytic meshes3on the surfaces of the metal meshes2. Through arrangements of the wavy channels102, the UVC-LED light boards104, the reflective layer105, the phptocatalytic meshes3, and the module body1being installed inside an air sterilization-and-disinfection device or an air conditioning conduit, the UVC-LED light boards104emits ultraviolet rays inside the wavy channels102for sterilizing the air flow passing the wavy channels102. Further, the reflective layer105reflects the ultraviolet rays emitted to the wavy channels102and forms the spilled ultraviolet rays that can be used to stimulate the photocatalytic meshes3disposed on the metal meshes2. Accordingly, the two bactericidal factors including pure ultraviolet irradiation sterilization and photocatalyst sterilization can be achieved.

Still further, several grooves103are formed in the middle and outside the corrugated boards101. The arrangement of the grooves103allows the UVC-LED light boards104to be disposed outside the corrugated boards101, and therefore the UVC-LED light boards104can be prevented from falling out when the module is in use.
