System for closing window automatically in rainy day

Abstract

The invention discloses a system for closing a window automatically in a rainy day. The system is arranged on a window frame or the side of the window frame and comprises a gear, a direct-current motor, a controller, a sensor and a control switch which are sequentially, wherein the gear comprises a driving gear and a driven gear; the driven gear is fixed on a window frame rotating shaft by a screw; the driving gear is arranged on an output shaft of the direct-current motor; the sensor comprises a photoelectric sensor and a humidity sensor; the photoelectric sensor is arranged on the edge of the window frame; the controller is a singlechip; and the driving gear and the driven gear are connected mutually by a transmission belt. In the system, the change of outside weather is perceived by the humidity sensor arranged outdoors, namely the sensor can send a signal automatically to the controller to control the motor to rotate in the rainy day, and after a window body is closed, the photoelectric sensor informs the controller to stop running. The integral device has a simple structure and is convenient to install, and a control box is arranged on the outer layer of the controller to protect the controller from being wet by rain.

Description

technical field [0001] The invention relates to an activity controller, in particular to an automatic window closing system in rainy days. Background technique [0002] At present, the windows in the family are opened and closed manually. People in the family usually have to go to work during the day. If there is no one at home, if you forget to close the window before leaving, and the weather changes, it is often because there is no one at home to take care of you. If the windows cannot be closed in time, rainwater will fall into the house, causing unnecessary troubles. Existing a lot of researches about automatic window switch control device in the prior art. Chinese patent CN86201385U discloses a device for automatic opening and closing of casement windows. The device is equipped with left and right brackets and pulleys on the window frame. There are driving wheels and motors on the brackets. Tension piles are installed on the window sash. Two opposite sashes form a lin...
