[0002] With the continuous development of modern technology, various devices are evolving towards integration and intelligence. A window opener is a machine used to control the opening and closing of windows. Window openers are increasingly being used in various aspects of life. For example, window openers can be installed in homes to allow ventilation. In large venues such as office buildings, airports, and train stations, where there are many windows, each window typically requires a corresponding window opener.
