Abstract
The invention provides a filtering sheet. The filtering sheet comprises a base layer; an ultraviolet light-emitting diode, which is coupled with the base layer; and a thin-film power supply, which isused for supplying power to the ultraviolet light-emitting diode. According to the invention, the ultraviolet light-emitting diode is coupled with and arranged on the base layer, so the filtering sheet can generate ultraviolet light; disinfection and sterilization are carried out on material fibers of all layers of the filtering sheet; microorganisms like bacteria and viruses intercepted by the whole filtering sheet can be killed by ultraviolet light; the functions of ultraviolet sterilization and disinfection are high; the killing effect on the bacteria and the viruses spread along with air is extremely high; convenient and highly-efficient prevention and sterilization functions are achieved; the risks of germ spreading and cross infection are reduced; and the health level of a user is improved.
Description
technical field [0001] The application belongs to the technical field of health care, and in particular relates to a filter and a protective article. Background technique [0002] Masks are one of the necessary important items for epidemic prevention and protection personnel, inspection and quarantine inspection and processing personnel, and are also protective equipment for people to prevent air pollution from endangering their health. Masks made of multiple layers of gauze can only filter out larger dust particles in the air, and have poor protection against bacteria and viruses transmitted through droplets and air, and cannot meet the requirements of new coronaviruses, SARS, bird flu, The need for personnel protection in the event of outbreaks such as H1N1 Influenza A and Middle East Respiratory Syndrome. The mask made of high-efficiency fiber filter material can have a good filtering protection effect on tiny particles, bacteria and viruses. Ultraviolet rays are widely...
