Aluminum alloy window capable of being closed automatically on rainy days
An aluminum alloy window capable of being closed automatically on rainy days comprises a window closing control device. According to the window closing control device, one end of a control switch is connected with a first electrode, and the other end of the control switch is connected with one end of a first resistor and a second pin of a 555 timer; the other end of the first resistor is connected with one end of a first capacitor and one end of a second resistor; the other end of the second resistor is connected with one end of a coil of a relay and one normally-open contact of the relay; a third pin of the 555 timer is connected with one end of a third resistor, and a fifth pin of the 555 timer is connected with one end of a second capacitor; the other end of the third resistor is connected with the base electrode of an NPN triode; the collector electrode of the NPN triode is connected with the other end of the coil of the relay; the other normally-open contact of the relay is connected with one end of a window closing motor; the other end of the window closing motor, the emitting electrode of the NPN triode, the other end of the second capacitor, a first pin of the 555 timer, the other end of the first capacitor and a second electrode are grounded. The aluminum alloy window can be closed automatically on the rainy days.
