In the medical field, for example, when used in a hospital, when a doctor visits a doctor, a partition is often placed on the doctor's special office. Its function is to separate the doctor and the patient. It will not be passed directly to the doctor, and the direct contact between the patient and the doctor will be cut off by placing an isolation screen;

Partitions are set up in areas such as banks, postal services, shopping malls, offices, conference rooms, etc., to prevent the corresponding business personnel from directly contacting the receptionist and causing infection. In the existing office areas, some are set on desks Transparent plastic partition to achieve isolation between people;

Although setting up screens or partitions between them can solve direct infection, there are still the following problems:

1. Although the isolation screen is directly used to separate the space and solve the direct infection of the virus, the ventilation effect of these rooms is not very good. Although direct infection is avoided, the virus still floats in the space and cannot be transmitted from the room by setting ordinary partitions. Fundamentally solve the problem of virus infection;
