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.
The main working principle of the air purification device 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 purification device in the prior art cannot effectively kill viruses carried in the air, so that the transmission of the viruses is difficult to block, the infectivity of the viruses is high, and the air purification device is not beneficial to the healthy life of people.
As described in the background, there is an urgent need for a device that can block the spread of new coronavirus through the airflow in the case that new coronavirus is spreading and there is no specific drug for a while. In order to solve the technical problem, the utility model provides an air disinfection device.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air sterilizer 100 according to an embodiment of the present invention; fig. 2 shows a partial implementation of the air sanitizer 100 of fig. 1.

Further, the air sterilizer 100 further includes a temperature sensor (not shown) for sensing the temperature of the heating assembly 14, and a controller (not shown) for controlling the heating assembly 14 to heat in a preset temperature range for a preset time period. In this way, the heating assembly 14 is controlled to continuously bake the filter member 12 at a certain temperature to effectively inactivate the new coronavirus attached to the filter net. Optionally, the predetermined temperature range is 50 ℃ to 75 ℃ so that the heating assembly 14 can heat the filter element 12 by radiation to a high temperature state capable of inactivating new coronavirus, for example, the filter element 12 is heated to 56 ℃ to 70 ℃ to inactivate viruses and bacteria at the high temperature. Optionally, the preset time is greater than or equal to 30 minutes to continuously bake the viruses and bacteria on the filter screen for a period of time at high temperature, so as to improve inactivation efficiency.
In some embodiments, heating assembly 14 is positioned upstream of the flow of air through filter element 12. That is to say, the external air flows into the air sterilization device 100 under the driving of the fan 30, and the air current flows through the heating component 14 and then flows to the filtering component 12, so the heating component 14 can heat the air current flowing through itself to play a certain sterilization and disinfection role, then the heated air current flows through the filter screen again, the bacteria and viruses can be attached to the filter screen, and are continuously heated by the heating component 14 on one side of the filter screen, so as to improve the utilization rate of the heating component 14, and improve the inactivation effect of the bacteria and the viruses. Alternatively, heating assembly 14 may be positioned downstream of the flow of gas through filter element 12, and may also heat filter element 12.
It should be understood that, in other embodiments, the sterilization module 10 includes a plurality of heating assemblies 14, the plurality of heating assemblies 14 are respectively disposed on two opposite sides of the filtering member 12 along the airflow direction, so as to arrange the heating assemblies 14 on both the upstream and downstream of the filtering member 12, so that the filtering member 12 is heated more uniformly, and the sterilization effect is better. Still alternatively, the heating element 14 is connected to the filter element 12, and the heating element 14 and the filter element 12 are integrally formed, so that the filter element 12 can be heated by the heating element 14.
Specifically, the heating assembly 14 includes a heating member 141 and a fin 143, the heating member 141 can be electrically heated, the fin 143 is disposed on the heating member 141 and thermally conducts with the heating member 141, and the heat generated by the heating member 141 is more efficiently radiated to the filter member 12 in the surrounding environment through the fin 143. It will be appreciated that the heater assembly 14 may have air vents formed therein to allow air flow through the heater assembly 14 and to prevent the heater assembly 14 from blocking the air flow.
It can be understood that, in some embodiments, the sterilization module 10 includes a plurality of sterilization modules 10, and the plurality of sterilization modules 10 are arranged in sequence along the airflow direction, so that viruses in the airflow can be inactivated for a plurality of times, and the inactivation effect on new corona viruses can be improved.

Therefore, the air flow is firstly purified by the air purification module 50, and then is further sterilized and disinfected by the sterilization module 10 and then discharged indoors, so that the quality of indoor air is improved.
Optionally, the air purification modules 50 include a plurality of air purification modules 50, and the plurality of air purification modules 50 are sequentially arranged along the airflow flowing direction, so that the airflow is purified for multiple times by the plurality of air purification modules 50, and the air purification effect is further improved.
