Thereby the voltage of the magnetic sensor is controlled not to overload so that the magnetic sensor is protected from burning.
- There are many prior art way for mosquito proof, such as installing screen windows or screen doors, using burning mosquito coil incense, spraying pesticide, etc. However in opening windows or doors, the screens cannot prevent the mosquito from flying indoors. The mosquito coil incense, and pesticide are harmful to human bodies.
- Furthermore, in many public places, the above mentioned ways can not be used. Thereby there is an eager demand for a novel design which can improve the defect in the prior art.
- Accordingly, the primary object of the present invention is to provide an insect proof wind generating device which is easily assembled with lower cost and high safety. A voltage of a magnetic sensor is controlled not to overload so that the magnetic sensor is protected from burning.
- To achieve above objects, the present invention provides a wind generating device which 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 which is driven by the motor.

However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. Referring to
FIG. 1 , the wind generatingdevice 1 of the present invention is illustrated. The present invention has the following elements. - A
body 10 has for example a long structure. However this do not confine the scope of the present invention. - One end of the
body 10 has awind inlet 11 and another end thereof has awind outlet 12. Thewind outlet 12 serves for draining wind from a wind driver in thebody 10. - A wind driver is a motor and two fans 22 (the number of fans are not confined in the present invention). The motor 21 is connected to the
fans 22 through a spindle. When the motor 21 operates, thefans 22 will be driven so as to generate wind. The wind flows to thewind outlet 12 of thebody 10 so as to form as an air wall. - A control device includes a
circuit board 31 which is electrically connected to a magnetic sensor, such as amagnetic reed switch 40 or an electromagnetic valve. Thecircuit board 31 will actuate themagnetic reed switch 40 so as to actuate the motor 21. - The wind generating device of the present invention uses high voltage AC current. To prevent the
magnetic reed switch 40 to be burned due to over heat or over current induced from the high voltage. A voltage reduction protection unit is used to protect themagnetic reed switch 40. Thereby the voltage of 110V or 220V inputted to thewind generating device 1 will descend to a voltage suitable for themagnetic reed switch 40 so as to protect themagnetic reed switch 40. - In use, referring to
FIGS. 2 to 4 , the wind-generatingdevice 1 is installed at a top of a door, such as apullable door 50 or apivotal door 60. Themagnetic reed switch 40 will be actuated. Then thecircuit board 31 will control the motor 21 to drive thefans 22 to rotate. Thus wind generates. Then the wind flows out from thewind outlet 12 of thebody 10 to the window or door so as to be formed as a wind wall for preventing the mosquito to flow indoors. The voltage reduction protection unit serves to descend a high voltage into a low voltage suitable for themagnetic reed switch 40 so as to protect themagnetic reed switch 40. - Referring to
FIG. 5 , the voltage reduction protection unit is illustrated. The voltage reduction protection unit is installed on thecircuit board 31. The voltage reduction protection unit has the following elements. Apower input unit 51 serves for providing AC current. The current then flows to a rectifiervoltage regulating unit 52 for voltage stability. Then anSSR circuit 53 is used to rectify the current synchronously so as to descend the voltage from 110V to 220V to a smaller current which is then inputted to a magneticdriving logic unit 54. Once the magnetic reed switch 40 actuates, the magneticdriving logic unit 54 serves to return sensing signals to theSSR circuit 53. Then theSSR circuit 53 will control thewind driver 55 to generate wind. The voltage reduction protection unit actually has the effect of protecting themagnetic reed switch 40 from burning. - The
wind generating device 1 with themagnetic reed switch 40 is used to detect the actuation of the device. This is because themagnetic reed switch 40 has preferred sensitivity. The wind generatingdevice 1 can blow wind. - Even a gap as smaller as 0.1 to 0.3 mm between the door (or window) and the wall, the wind generating
device 1 can generate wind to prevent the mosquito from flowing indoors. - Otherwise, the
magnetic reed switch 40 can prevent current to flow out. Moreover, themagnetic reed switch 40 is cheap and is easy to be assembled. - The present invention is thus described, it will be obvious that the same may be varied in many ways.
