Abstract

The invention provides an ultraviolet disinfection device based on optical waveguide, and a terminal. The ultraviolet disinfection device comprises an ultraviolet light source, an optical coupler andan optical waveguide light-guiding thin film, wherein the optical waveguide light-guiding thin film comprises a basal layer and a flat-slab light-guiding thin film from bottom to top; the refractive index of the basal layer is smaller than the refractive index of the flat-slab light-guiding thin film; the ultraviolet light source is used for providing ultraviolet light used for disinfection; the optical coupler is used for receiving the ultraviolet light and coupling and importing the ultraviolet light into the optical waveguide light-guiding thin film; and the optical waveguide light-guidingthin film is transparent for the ultraviolet light and is used for receiving the ultraviolet light to disinfect the surface of the optical waveguide light-guiding thin film. Through the optical waveguide light-guiding thin film, the ultraviolet light imported from the optical coupler is received, the ultraviolet light generates total reflection in the optical waveguide light-guiding thin film anddoes not generate attenuation along with distance, and the ultraviolet light only generates light leakage on a dirt adhesion position so as to generate small injuries on the human body. The device issimple, can be integrated to display equipment to carry out ultraviolet disinfection on the display equipment if required, and is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet disinfection devices, and in particular relates to an optical waveguide-based ultraviolet disinfection device and a terminal. Background technique [0002] Human beings have been plagued by various diseases for a long time, and many diseases are caused by human contact with bacteria or viruses through hands. Washing your hands frequently and properly is crucial to reducing the spread of disease, but it can make our lives safer if we can eliminate viruses at their source - the many surfaces that our hands touch every day. Various buttons, handles, keyboards, mobile phone screens and other objects that cannot be avoided in our daily life are often the main source of various bacteria and viruses, especially mobile phone screens. Studies have shown that the amount of bacteria on mobile phone screens is higher than that of randomly collected ATMs. There are many keyboards, toilet flush buttons, an...
