Description

Technical Field

[0001] The present 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] Sterilization and disinfection are crucial tasks in fields such as healthcare, food processing, water treatment, and air purification, ensuring the sanitation and safety of the environment and products. Traditional disinfection methods, including chemical disinfectants, thermal sterilization, and ozone disinfection, can achieve these goals to a certain extent, but they often have drawbacks. For example, chemical disinfectants may leave residues, posing a potential threat to human health; thermal sterilization requires high temperatures and pressures, consuming significant energy and requiring high corrosion resistance from the equipment; and ozone disinfection requires specialized equipment to generate and control ozone concentrations, and ozone itself is toxic and corrosive. In recent years, with the advancement of optoelectronics technology, deep ultraviolet (DUV) LED light sources have shown great potential for application in sterilization and disinfection due to their high efficiency, environmental friendliness, and lack of chemical residues. Deep ultraviolet light, typically in the 200-300 nanometer wavelength range, possesses powerful bactericidal properties, capable of disrupting the molecular structure of microbial DNA or RNA, achieving rapid sterilization. Compared with traditional mercury lamps, deep ultraviolet LED light sources have the advantages of small size, long life, low energy consumption, and no mercury pollution. The present invention is a deep ultraviolet LED light source sterilization and disinfection device without negative pressure.

By turning the hand wheel 231, the position of the No. 2 seat 25 can be accurately adjusted to ensure that the two sets of conveyor belts 261 are in close contact with the left and right sides of the object respectively, so that the object can move smoothly on the conveying roller 241, which is convenient for continuous disinfection. The No. 8 motor 114 is operated to make the No. 1 connecting belt 116 drive the movable plate 112 to open and close, which can create a closed disinfection environment. The dust on the surface of the object is cleaned by the dust removal nozzle 123, which effectively avoids the influence of dust on the sterilization effect. 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 object. During the disinfection process, some gas 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.
