Description
Technical Field
The invention relates to the field of air purification, in particular to an air purifier and an air purification method.
Background
Currently, airborne transmission is an important mode of transmission of viruses. Airborne transmission refers to the entire process of air invasion into a new susceptible host after the pathogen has been expelled from the source of infection.
The three modes of airborne transmission of infectious diseases are: droplet propagation, droplet nucleus propagation and dust propagation.
When a patient breathes, speaks loudly, cries, snores, coughs or sneezes, pathogens of respiratory infectious diseases exist in mucus on the surface of a respiratory mucosa or in fragments of ciliated epithelial cells, a large amount of mucus droplets containing the pathogens can be ejected from the nasopharynx, the size is small (15-100 mu m), and the mucus droplets can be suspended in the air for a short time (generally, no more than a few seconds). The extent of droplet spread is limited to close contact between the patient or the carrier. Epidemic cerebrospinal meningitis, influenza, pertussis, etc. can be transmitted in this manner. Crowded temporary shelters, detention houses or prisons, numerous cabins for passengers, station waiting rooms are common places where such spread occurs.
The droplet nucleus transmission means that droplets containing pathogens discharged from an infection source are suspended in the air and lose water by evaporation, leaving minute particles of protein coat, containing pathogens, and forming droplet nuclei. The spray core can be suspended in air for hours or even longer, and the floating distance is longer. Inhalation of the droplet nucleus with the pathogen causes infection, known as droplet nucleus transmission. Pathogen resistance can spread infectious diseases such as diphtheria, scarlet fever, tuberculosis, etc., through the droplet nucleus.
For the transmission of dust, secretion containing pathogens falls on the ground in large droplets, and forms dust after drying, and the dust is resuspended in the air due to the movement of people and is inhaled by people to cause the transmission. All pathogens with strong resistance to the outside, such as tubercle bacillus, can be transmitted by dust.
The occurrence of airborne transmission depends on a variety of conditions, among which population density, hygiene conditions, the proportion of susceptible persons in the population plays a decisive role.
The main working principle of the air purifier in the prior art is as follows: air is pumped into the machine and filtered through the built-in filter screen, so that the dust, peculiar smell and toxic gas nuclei can be filtered to kill partial bacteria. However, the air purifier in the prior art cannot effectively kill viruses carried in the air, and further is difficult to block the transmission of the viruses (especially the coronavirus), so that the viruses have high infectivity and are not beneficial to the healthy life of people.
The novel coronavirus pneumonia is an acute infectious pneumonia, and the pathogen is a novel coronavirus which is not found in human before. The transmission of coronaviruses via respiratory droplets and intimate contact is the main transmission route. There is a potential for transmission via aerosols in the case of prolonged exposure to high concentrations of aerosols in a relatively closed environment. There may be aerosol transmission risks in enclosed, unventilated locations, requiring intensive preventive and isolation treatment.
According to the research of medical teams, the new coronavirus can lose activity in the environment of 56 ℃ for 30min, and a disinfection product is urgently needed to effectively purify and disinfect indoor air in sealed areas with large people flow (such as elevators, hospitals and other high-risk areas).
In addition, the air purifier in the prior art has difficulty in maintaining the predetermined temperature in the area where the air passes through so as to ensure effective killing of viruses (especially, the new coronavirus).
