Background
According to epidemic situations, human beings are worried about health and even life by different pathogenic microorganisms in the nature while continuously struggling with the nature. From epidemic situation protection, because people lack worship about nature and do not protect microorganisms (bacteria, viruses and the like) which harm the health of people at present, when the epidemic situation comes and the bacteria and viruses flood, we have no policy, and no three ways can be left for infectious disease circulation: the infection source, the transmission path and the susceptible population lack one but do not cause diseases, however, one link is only cut off by people, and the people are safe and do not cause diseases. The infectious sources and susceptible people are often difficult to control, the health consciousness and the precaution capability of the whole society need to be improved, and simultaneously the physical quality needs to be improved in an all-round way, the immunity is enhanced, and the cutting of the transmission path is often the most effective and direct method for preventing various infectious diseases.
At present, ultraviolet sterilization and disinfection are widely adopted, and ultraviolet rays with proper wavelengths can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in cells of a microorganism organism to cause death of growing cells and (or) regenerative cells, so that the effects of sterilization and disinfection are achieved. The ultraviolet disinfection technology is based on modern epidemic prevention science, medicine and photodynamics, and various bacteria, viruses, parasites, algae and other pathogens can be directly killed by irradiating the surfaces of air and objects with specially designed UVC band ultraviolet light with high efficiency, high intensity and long service life.
Besides the common ultraviolet sterilization, the sterilization can be carried out by adopting negative ions, the negative ions have stronger sterilization effect, and the principle is that the negative ions can change the protein structure of bacteria or viruses (the two polarities of proteins are reversed) or transfer energy, so that the activity of microorganisms such as bacteria and viruses is reduced and the microorganisms die. The negative ions have no side effect on human bodies, and the sterilization device taking the negative ion technology as the core can refresh the indoor environment, eliminate bacteria, viruses and harmful microorganisms and has important significance on the health preservation of human bodies.
