[0002] The machine used to open and close windows is called a "window opener" or "window opener". It is generally called a "window opener" abroad, and is mostly called a "window opener" in China. Most modern buildings are based on curtain walls. To ensure better ventilation and smoke exhaust effects, windows must be designed and arranged on the facade or plane. However, sometimes manual opening is impossible due to the height of the window. Therefore, electric window openers were introduced based on manual window openers, which not only realize automation and intelligence, but also extend the functions of buildings.

[0003] There are mainly several types of electric window openers, including chain type, push rod (internal screw) type, and bridge (rack) type. Among them, the chain type window opener takes up little space and is mainly used for top-hung windows, bottom-hung windows, and some middle-hung windows and other types of windows that need to be opened for ventilation or smoke exhaust. Due to its compact structure, it is particularly suitable for opening bottom-hung windows. However, for wider and larger windows, an electric locking mechanism should be used to ensure the sealing of the windows. The chain type window opener can be built into the window frame, which is simple and beautiful.
