Insect proof wind generating device

Abstract

An insect proof wind generating device comprises a body having an wind inlet and a wind outlet; a wind driver being installed within the body; the actuation of the wind driver being controlled by a circuit board; the circuit board being connected to a magnetic sensor; the magnetic sensor serving for detecting the opening and closing of a door or a window. When it is determined that the door or window is opened, the magnetic sensor will actuate wind generating device to blow wind. The wind driver includes a motor electrically connected to the circuit board and at least on fan driven by the motor. The circuit board is installed with a voltage reduction protection unit for reducing a voltage reduction protection unit for reducing a high voltage to a low voltage suitable for the magnetic sensor. The voltage reduction protection unit is installed on the circuit board;

What is claimed is: 
     
         1 . An insect proof wind generating device comprising:
 a body having an wind inlet and a wind outlet; a wind driver being installed within the body; the actuation of the wind driver being controlled by a circuit board; the circuit board being connected to a magnetic sensor;   the magnetic sensor serving for detecting the opening and closing of a door or a window; when it is determined that the door or window is opened, the magnetic sensor will actuate wind generating device to blow wind.   
     
     
         2 . The insect proof wind generating device as claimed in  claim 1 , wherein the wind driver includes a motor electrically connected to the circuit board and a fan driven by the motor. 
     
     
         3 . The insect proof wind generating device as claimed in  claim 1 , wherein the circuit board is installed with a voltage reduction protection unit for reducing a high voltage to a low voltage suitable for the magnetic sensor. 
     
     
         4 . The insect proof wind generating device as claimed in  claim 3 , wherein the voltage reduction protection unit is installed on the circuit board;
 the voltage reduction protection unit has a power input unit serves for providing AC current; the current then flows to a rectifier voltage regulating unit for voltage stability; then an SSR circuit is used to rectify the current synchronously so as to descend the voltage to a smaller current which is then inputted to a magnetic driving logic unit; once the magnetic reed switch actuates, the magnetic driving logic unit serves to return sensing signals to the SSR circuit; then the SSR circuit will control the wind driver to generate wind; the voltage reduction protection unit has the effect of protecting the magnetic reed switch from burning.   
     
     
         5 . The insect proof wind generating device as claimed in  claim 1 , wherein the magnetic sensor is one of a magnetic reed switch or an electromagnetic valve.
