1. Field of the Invention
The present invention relates to an air blown electric switch device, and particularly relates to an air blown electric switch device, which is controlled by detecting the pressure.
2. Description of Related Art
Conventionally, switches of electric devices, such as lamp, are mechanical components. The conventionally mechanical switches are mainly divided into two types. One is switched by pressing. When a conductive component is pressed up or down, circuits nearby the conductive componet are switched to be turned on or turned off, such as membrance switches. The other is a guillotine switch, which is controlled by changing the angle of the switching component. It is commonly used and installed on the walls to switch illuminatning device.
However, all the conventionally mechanical switches are manual control switches, such that there must be sufficient spaces for an operator to controll the swithces. Furthermore, the conventionally mechanical switches are continuing touched by operators, such that the switches may be smudged by operators' dirty hands. It may cause healthy problems. Thus, it does not fill the bill of nowdays that the conventional switches are controlled by touching.
The present invention is to provide an air blown electric switch device, which is controlled by detecting pressure, so as to overcome the problems mentioned above.
The present invention is to provide an air blown electric switch device, so as to avoid virus infection by touching.
The present invention is to provide an air blown electric switch device, which is applied in a lamp, a fan, or a motor . . . etc. The air blown electric switch device includes a body, a pressure detector, and controlling circuits.
The pressure detector is installed inside the body for detecting a pressure and generating a pressure signal according to the pressure. The controlling circuits are installed inside the body and connected with the electric device and the pressure detector for receiving the pressure signal and controlling the electric device to turn on or turn off.
The following provides exemplary embodiments of the present invention with reference to the accompanying drawings.

For example, the electric device 100 can be a home appliance likely to be a fan, illuminating devices likely to be a lamp, or a motor . . . etc. The air blown electric switch device comprises a body 10, a pressure detector 20, and controlling circuits 30. The pressure detector 20 for sensing the pressure of the air to generate a pressure signal can be installed inside or outside the body 10. The controlling circuits 30 for connecting the electric device 100 with the pressure detector 20 and receiving the pressure signal from the pressure detector 20 is installed inside the body 10. The pressure signal is transferred into a voltage signal for switching the electric device 100 to turn on or off by the controlling circuits 30.
Next, according to an embodiment of the present invention, the electric device 100 is preferably taken an example to be an electric candle or a lamp. The air blown electric switch device is applied in the electric candle or the lamp.

According to these embodiments of the present, the diameter of the air blown holes is preferably less than 3 mm, so as to gather the pressure up without extra influence of other air flow. Specifically, a threshold pressure can be set according to the embodiment of the present invention. If the pressure detected by the pressure detector is higher than the threshold pressure, the pressure signal would be generated. Therefore, in the manner, the electric device can not be bothered any extra air flow. The utility of the air blown electric switch device can be improved.
According to the present invention, the air blown electric switch device is controlled by pressure, and the electric device is further controlled by the air blown electric switch device. It is easy for an operator to blow an air to switch the electric device. The air blown electric switch device of the present invention takes several advantages. The volume of the air blown electric switch device is small. The current consuming is saved, for example, the static current is about 250 μA/4.5 V. The life of the air blown electric switch device can be prolong, and getting an electric shock can be avoided, due to no hand touching. Furthermore, if the air blown electric switch device is installed in a public place, the way of viruses' infection by touching can be avoided.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
