Technical Field

[0001] The invention belongs to the technical field of sterilization and disinfection, and relates to a plasma sterilization and disinfection wardrobe. Background Art

[0002] Plasma is the fourth state of matter. Since the 1990s, research and technological applications of plasma gas discharge have rapidly developed, encompassing diverse fields including materials science, biology, chemistry, and medicine. Plasma sterilization and disinfection is one such method. Plasma sterilization and disinfection have evolved from utilizing the physical effects of electric field tearing and electrostatic adsorption to utilizing nitrogen and oxygen active particles, high-energy particles, ultraviolet light, and ozone generated by plasma actuators.

[0003] Currently, disinfection cabinets for home or medical use typically use a combination of ozone, ultraviolet light, and high temperatures for sterilization. Existing disinfection cabinets, when using ozone for sterilization, cannot quickly remove residual ozone from clothing, making them unsuitable for people allergic to ozone. High-temperature sterilization cannot sterilize damp clothing or clothing made of materials that are not heat-resistant, which can easily damage clothing and pose a safety hazard. Furthermore, existing plasma disinfection cabinets fail to effectively cover the entire cabinet during the disinfection process, and they also suffer from incomplete disinfection and prolonged sterilization times. Summary of the Invention
