Plasma hand disinfection device

Abstract

The invention discloses a plasma hand disinfection device which is mainly applied to disinfection of human hands. The disinfection device mainly comprises an air inlet, a fan, a water tank, a plasma generator, an ozone decomposition device, a plasma excitation power supply, an infrared induction switch, an air outlet and a disinfection machine shell. The working principle of the disinfection device is as follows: the plasma generator is utilized to generate plasma, the fan works to blow the generated plasma to the hands to disinfect the hands, and the disinfection mode is relatively safe. Airpasses through the water tank before entering the plasma generator so as to increase the air humidity, so that the concentration of O and OH free radicals generated after plasma ionization is increased, and the disinfection effect is enhanced. The air carrying the plasma absorbs ozone through an ozone adsorption device, so that the ozone emission reaches the standard, adverse effects caused by excessive ozone concentration are avoided, and the safety is guaranteed while the disinfection effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sterilization and disinfection, in particular to a plasma hand disinfection machine for hand disinfection. Background technique [0002] At present, the world is facing the threat of a new type of coronavirus, and effective sterilization methods are an important measure to avoid cross-infection between people. Traditional hand disinfection methods include disinfectant disinfection, ozone disinfection, sodium hypochlorite disinfection, ultraviolet disinfection and other "wet" disinfection technologies, which have disadvantages such as poor disinfection effect and human injury caused by residual by-products. Plasma disinfection technology is a new type of green, dry disinfection technology developed in recent years. It has the advantages of no chemical residue and safe operation, and can overcome the defects of existing disinfection methods. [0003] Chinese patent CN202568952U discloses a plasma hand clea...

AI Technical Summary

Problems solved by technology

Chinese patent CN104146858 discloses a low-temperature plasma medical hand disinfection machine. When using this disinfection machine, users need to place their hands on an accessible grounding net. The plasma electrode generates plasma to disinfect hands, which also has potential safety hazards.

Chinese patent CN103357114A discloses a plasma hand disinfection machine, which uses a plasma generator to generate plasma, and uses a fan to blow the generated plasma to the hands to disinfect the hands. The main disinfection substance is ozone generated by the plasma. Risk of ozone poisoning

[0004] In summary, the existing plasma hand disinfection method has potential safety hazards, which limits its practical application.
