However, the effect is limited. Only part of patients carry a common disposable medical mask, and the virus release source is not effectively isolated. The design collects and kills pathogens of the infection source and controls the spread of epidemic situations from the infection source. The medical staff is in the same space, breathing the same air and touching the common goods with the patient during the treatment, because the pathogens are present in the air. Medical personnel need to be closely protected. The patients who are confirmed to be isolated by the hospital cause psychological burden to the patients, so that the patients do not want to be matched with doctors to treat the diseases. Suspected, close contact persons, temporarily isolated, if virus carriers, will also be airborne. The virus carrier may cause the accompanying of the same ward and the cross infection of other patients and other persons during the treatment. The isolation of mild patients at home in some countries is also the main reason for the family outbreak. From the perspective of epidemic control, the main measures taken by countries around the world are to block virus transmission at the end or middle end of epidemic, but only by these measures, the epidemic situation cannot be completely controlled in time. The isolation effect of the whole people is obvious, but the cost is too large. We think that measures are taken at the source of epidemic disease control through virus isolation, collection and killing, and the air cleanness is guaranteed to be the most important, so the system is developed. At present multifunctional mask implements from the source and prevents accuse, realizes "accurate protection, accurate killing".

The structure has the advantages of small volume, simple structure, low cost and good market prospect.
