Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of disinfection devices, in particular to a disinfection device for controlling the spread of biological infectious diseases. BACKGROUND

[0002] An infectious disease is a disease caused by various pathogens that can be transmitted between humans, animals, or humans and animals. Most of the pathogens are microorganisms, and a small part is caused by parasites, which is also called parasitic disease. Infectious diseases are infectious diseases that can be transmitted to another individual or species through various routes. Usually, such diseases can be transmitted by direct contact with infected individuals, body fluids and excretions of infected individuals, and objects contaminated by infected individuals, through air transmission, water transmission, food transmission, contact transmission, soil transmission, vertical transmission (mother-to-child transmission), body fluid transmission, fecal-oral transmission, etc. Infectious disease disinfection is to use physical or chemical methods to eliminate pathogens on different transmission media, so as to cut off the transmission route and prevent and control the occurrence of infection. The purpose is: (1) to prevent pathogens from spreading in society and causing epidemics to occur. (2) Prevent the infected from being infected with other pathogens and develop complications and cross-infection. (3) Also protect medical staff from infection.

[0003] With people's increasing emphasis on health and continuous improvement of the awareness of preventing diseases and bacteria, the external public environment outside the home is becoming increasingly complex, and the risk of various bacteria and viruses is increasing. For example, public toilets (especially toilets used by patients such as hospital toilets), hospitals, meat and animal markets, epidemic areas, and places contaminated by bacteria and viruses, etc. Due to work, life, and learning needs, people cannot avoid entering these places, and the opportunity and possibility of their shoe soles contacting contaminated bacteria and viruses (such as severe infectious bacteria and viruses, hepatitis viruses, HIV, tuberculosis viruses, syphilis, avian influenza, African swine fever, sand viruses, parasites, and filth) cannot be ruled out. Therefore, the risk of people unknowingly bringing harmful substances such as bacteria, viruses, and parasites back home through their shoe soles is extremely high. In addition, various biopharmaceutical factories, breeding farms, research sites, and epidemic areas require isolation of external bacteria, viruses, and microorganisms for health and safety considerations. This requires the use of shoe sole disinfection devices to prevent the spread of infectious diseases.

[0004] At present, the disinfection device for shoe sole disinfection is usually a disinfection tank, that is, the shoe sole is soaked in disinfectant during disinfection, so a large amount of disinfectant is taken away when the shoe sole leaves the cleaning and disinfection tank, resulting in a large amount of disinfectant waste.
