Description

Spray disinfection device and disinfection method thereof

Technical Field

The invention relates to a disinfection device, in particular to a spray disinfection device and a disinfection method thereof.

Background

The oral cavity is an ecological system of multiple bacteria, and the oral cavity impression is directly contacted with saliva and even blood of a patient, and the plaster model is formed by reproducing the oral cavity impression, so that various bacteria in the oral cavity of the patient, especially hepatitis B virus, tubercle bacillus and the like, are extremely harmful to human bodies, and the current epidemic Human Immunodeficiency Virus (HIV) is more remarkable. The operation of the model is directly contacted with staff, so that cross infection is very easy to cause. The current disinfection technology can be generally classified into physical disinfection/sterilization and chemical disinfection/sterilization, wherein electrolyzed water has been attracting attention in recent years due to low cost, simple equipment, high safety, remarkable effect, low residual effect and less environmental pollution.

The acidic electrolyzed water is prepared by electrolyzing softened tap water containing sodium chloride in an ion diaphragm electrolyzer to generate HOCl at an anode, thus obtaining the acidified water with low pH value, high oxidation-reduction potential and low concentration of available chlorine. The action mechanism is as follows: as the PH of the acidic electrolyzed water is below 2.5+/-0.2 and the ORP is higher than 1120+/-70 mv, the normal living environment of microorganisms such as bacteria, fungi and viruses is destroyed, the cell membrane potential of the microorganisms is changed, and the cell membrane permeability is increased and the cell metabolizing enzyme is destroyed to generate the bactericidal effect. The acid electrolyzed water has the effect of killing viruses, and besides low pH and high ORP, the free residual chlorine and sodium hypochlorite enhance the effect of killing viruses by the acid water. The research result shows that the acid electrolyzed water has wide antibacterial spectrum and strong bactericidal power, and can kill HP, escherichia coli, pseudomonas aeruginosa, staphylococcus aureus and other bacteria within 30 seconds; 30s can kill HBV, HCV, HIV and adenovirus; 25s can kill filamentous epidermidis and candida albicans; the agent can kill some bacteria such as bacillus with strong resistance to chemical disinfectant after 15 min. The acidic electrolyzed water is reduced into tap water after being used, and free chlorine in the water has little influence on human bodies and environment, thus being a safe, efficient and convenient environment-friendly disinfectant. However, the denture metal and the cast of the oral cavity cannot be rinsed with water, so the acidic electrolyzed water still cannot be directly used for disinfection of the denture metal and the cast of the oral cavity.

In patent application 200510061699.3, a method for atomizing acidic electrolyzed water by ultrasonic waves is proposed, which is expected to effectively solve the problems, but a nozzle of the sterilizing device is arranged at the bottom of a sterilizing cabin, so that sterilizing objects to be sterilized cannot be completely sterilized without dead angles, and the technical problem of poor sterilizing effect is caused.
