Description

Technical Field

The main application places are: biopharmaceuticals, scientific research institutions, disease control centers, large hospitals, university research, biological cleanliness and various clean areas of application.

[0003] The transfer window is an auxiliary equipment of the clean room. It is mainly used for the transfer of small items between clean areas and between clean areas and non-clean areas to reduce the number of times the clean room door is opened and minimize the pollution of the clean room. An ultraviolet lamp is installed in the transfer window. The items enter the clean area after being disinfected by ultraviolet radiation. Ultraviolet rays are a kind of electromagnetic radiation with a wavelength of 190 to 350nm. Among them, 253.7nm has the strongest bactericidal power. It can form dimers between adjacent pyrimidine bases on the DNA chain, inhibit DNA replication, and cause mutations or death. The bactericidal power of ultraviolet rays is related to factors such as ultraviolet intensity, irradiation time, temperature and humidity.

[0004] The existing laminar flow transfer window generally requires manual opening of the doors on both sides of the transfer window to take out the goods, which is rather troublesome. Moreover, when the doors on both sides of the transfer window are opened at the same time, air convection is easily formed, thus affecting the working environment of the workshop.
