Preferably, the ultraviolet sterilizing and disinfecting lamp consists of one or more L ED ultraviolet light-emitting diodes.

Further, the peak wavelength of the one or more L ED UV LEDs is 270-280

And (4) nano.

Preferably, the one or more L ED UV LEDs are mounted on the windward side of the fan outlet in the air filtration system.

The invention has the beneficial effects that: because the ultraviolet sterilization and disinfection lamp is additionally arranged in the air filtering system, the air filtering system can filter haze dust and pollen and can inactivate bacteria and viruses. The transparent mask is provided with the magnetic rubber strips, so that the transparent mask is easily arranged on the front hoop and the stand columns on the two sides, which are made of magnetic materials, or is detached, and is convenient to store and carry; the I/O port and the program programming port of the singlechip on the control circuit are connected to an external socket, various sensor modules and an execution mechanism can be connected from the outside, and the program of the control circuit can be modified from the outside, so that the control circuit is particularly suitable for the study of scientific and technological activities of teenagers and brains and software programming, is a practical protective article in haze days, flu seasons and pollen seasons, enlarges the application range of the product, and is particularly suitable for teachers and students who create guest teaching under the online.
