Detailed description of the invention

Below in conjunction with embodiment, this utility model is described further. The explanation of following embodiment is only intended to help and understands this utility model. Should be understood that; for those skilled in the art; under the premise without departing from this utility model principle, it is also possible to this utility model carries out some improvement and modification, these improve and modification also falls in this utility model scope of the claims.

The air cleaning screen window device of the present embodiment, including: filter screen 1, water smoke device 2, electrostatic equipment 3, window screen frame 4 and sewage box 5.
