Description

Technical Field

[0001] The invention relates to the technical field of sterilization and disinfection, and in particular to a deep ultraviolet LED light source sterilization and disinfection device without negative pressure. Background Art

[0002] In the fields of medical treatment, food processing, water treatment and air purification, sterilization and disinfection is a vital task to ensure the sanitation and safety of the environment or products. Traditional sterilization and disinfection methods include the use of chemical disinfectants, thermal sterilization, ozone disinfection, etc. Although these methods can achieve the purpose of sterilization and disinfection to a certain extent, they often have some shortcomings. For example, chemical disinfectants may leave residues, posing a potential threat to human health; thermal sterilization requires high temperature and pressure, high energy consumption and high corrosion resistance requirements for equipment; ozone disinfection requires special equipment to generate and control ozone concentration, and ozone itself has certain toxicity and corrosiveness. In recent years, with the development of optoelectronic technology, deep ultraviolet (DUV) LED light sources have shown great application potential in the field of sterilization and disinfection due to their advantages such as high efficiency, environmental protection and no chemical residue. The wavelength range of deep ultraviolet light is usually between 200-300 nanometers, with strong bactericidal ability, which can destroy the molecular structure of microbial DNA or RNA, thereby achieving a rapid sterilization effect. Compared with traditional mercury lamps, deep ultraviolet LED light sources have the advantages of small size, long life, low energy consumption, no mercury pollution, etc. The present invention is a deep ultraviolet LED light source sterilization and disinfection device without negative pressure.

The operation of the No. 3 motor 125 can make the dust removal nozzle 123 clean the dust on the surface of the object, which effectively avoids the influence of dust on the sterilization effect. The dust nozzle 123 swings to further improve the dust removal effect. The deep ultraviolet rays emitted by the sterilization lamp 142 are used to irradiate and sterilize the objects. The ultraviolet reflective coating on the reflector 372 can effectively reflect the deep ultraviolet rays to achieve comprehensive disinfection of the surface of the objects. During the disinfection process, some gases may be generated inside the box 1. Through the design of the exhaust fan 15, these gases can be effectively discharged into the external environment, ensuring the cleanliness and safety of the operating environment. Running the No. 6 motor 1611 to control the opening and closing of the dust curtain 163 can effectively prevent external dust from entering the inside of the box 1, maintain the cleanliness of the box 1, and provide a more hygienic environment for the disinfection process.
