Description
Technical Field
The utility model relates to an air purification field particularly, relates to an air purification device and have its air purifier.
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.
In the case of droplet nuclear transmission, droplets containing pathogens are discharged from an infectious agent and suspended in the air, and water is lost by evaporation, leaving smiling 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.
