Mode for Carrying Out the Invention
[0025] Hereinafter, with reference to the drawings in the embodiments of the present invention, the technical means in the embodiments of the present invention will be clearly and completely described. As is obvious, the following embodiments are only some embodiments of the present invention, not all embodiments. Hereinafter, the description of at least one exemplary embodiment is merely illustrative and does not limit the present invention and its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are all included in the protection scope of the present invention.
[0026] For the sake of convenience of description, in this specification, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. are used to describe the spatial positional relationship between a certain component or feature shown in the drawings and other components or features. As can be understood, the spatial relative terms are intended to include not only the orientation of the components shown in the drawings, but also different orientations during use or operation. For example, if the components in the drawings are turned upside down, the components described as "above other components or structures" or "on other components or structures" will be positioned as "below other components or structures" or "under other components or structures". Therefore, the exemplary term "above..." can include two orientations, namely "above..." and "below...". This component can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative notations used in this specification will be interpreted accordingly.
[0027] In addition, in the appended claims and this specification, the terms "comprising", "including" or any other variation are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to this process, method, article or apparatus. Without further limitation, an element limited by the term "comprising one" does not exclude the presence of another identical element in the process, method, article or apparatus comprising that element.

The OH radicals and some O 2- radicals decompose the organic substances, bacteria, viruses, etc. in the air blown by the blower fan 2 in the air supply pipe 1 into CO 2 and water. Some O 2- radicals are blown to the object to be disinfected by the air flow, and decompose the organic substances, bacteria and viruses on the surface of the object to be disinfected into CO 2 and water. The virus killing and sterilizing module and the disinfection device of this embodiment can reach a virus and bacteria killing rate of 99.9% on the surfaces of various articles under the action of photocatalyst and ultraviolet rays, and also have the effect of air purification.
