Summary of the invention

The purpose of this utility model promptly is a kind of air cleaning facility is provided, so that the circulation rapidly that purifies air, thereby improve the speed and the efficient of indoor or regional space air cleaning.

To achieve these goals, the utility model utilization is provided with the housing of opening and is installed in housing interior rotating driving device, flabellum and ultraviolet radiation device and constitutes a kind of air cleaning facility; Rotating driving device is arranged on enclosure interior and has a rotating shaft; Flabellum connects in the rotating shaft of rotating driving device, and its surface is coated with photocatalyst layer or is arranged with the photocatalyst net; Ultraviolet radiation device is arranged in the housing, and the ultraviolet ray of being sent is shone the photocatalyst layer or the photocatalyst net on flabellum surface.

Based on above structure, when the photocatalyst layer on the ultraviolet ray irradiation flabellum surface of sending when ultraviolet radiation device or photocatalyst net, can produce the photocatalyst air purifying effect; And rotating driving device then can make the circulation rapidly that purifies air, thereby improving the speed and the efficient of indoor or regional space air cleaning when driving the flabellum rotation.

Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model air cleaning facility.
