Roll-up dust-removing screen window

Abstract

The invention provides a winding type dust removal screen window. The winding type dust removal screen window comprises a main frame and a roll dust removal net. An upper scroll and a lower scroll are correspondingly arranged on the upper and lower sides of the frame. The shaft ends of the upper scroll and the lower scroll are correspondingly arranged in an upper bracket and a lower bracket in a penetrating manner to form rotational connection. The extending ends, going out of the lower bracket, of the lower scroll are each sleeved with a rotating wheel. The front side face of the main frame is a screen window face, and the rear side face is an installation face which is fixed to a window frame. A pressing frame is arranged on the screen window face, the pressing frame and the upper bracket are connected through a hanging assembly, and the pressing frame and the lower bracket are fixedly connected by a lower connecting rod. The main frame is equipped with a dust removal net channel. The periphery of the main frame and the periphery of the pressing frame are closely sealed together, and the periphery of the main frame and the periphery of the window frame are closely sealed together. The roll dust removal net includes a piece of rectangular mesh fabric. The two ends of the mesh fabric are each wound to form a roll. The middle of the mesh fabric is arranged in the dust removal net channel in a penetrating manner, so that the roll at one end sleeves the upper scroll, and the roll at the other end sleeves the lower scroll.

AI Technical Summary

Problems solved by technology

[0005] Due to the need to trap a large amount of dust, the dust filter is easy to get dirty, and the mesh will be blocked, which will affect the air permeability, so it needs to be replaced frequently (3-7 days)

Conventional window screen cleaning or replacement is cumbersome, not suitable for dust removal screens that need to be cleaned or replaced frequently
