Abstract
A wireless power switch control device, comprising: comprising: a detection and transmission circuit for detecting an obliquity of an object, upon the obliquity of said object reaching to a specified level, said detection and transmission circuit will transmit a wireless signal; and a receiving and control circuit upon receiving the wireless signal from said detection and transmission circuit will turn off a power of a outlet so as to prevent sparking of an electric wire.
Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to a power switch. More particularly, the present invention relates to a wireless power switch control device.
BACKGROUND OF THE INVENTION
[0002] Generally speaking, a Christmas tree in accordance with the prior art has a plurality of lamps. These lamps are connected to a power outlet via an electric wire. Upon the Christmas tree tipping and providing power continually, may be arisen a sparking of an electric wire and then caused a fire accident. In addition, a wire-control Christmas tree is provided in the market, which controlled the power ON/OFF by way of a wire and a switch. However, if the Christmas tree tipping and not turning off the power timely by the switch, may be arisen a sparking of an electric wire and then caused a fire accident yet.
[0003] As a result, an improved wireless power switch control device that reduces damage by the sparking of an electric wire is needed.
SUMMARY OF THE INVENTION
[0004] It is an object of the present invention to provide a wireless power switch control device for protecting the outlet and providing security of power.
[0005] In accordance with one embodiment of the invention, an wireless power switch control device is provided comprising: a detection and transmission circuit for detecting an obliquity of an object, upon the obliquity of the object reaching to a specified level, the detection and transmission circuit transmits a wireless signal; and a receiving and control circuit upon receiving the wireless signal from the detection and transmission circuit turns off a power of a outlet so as to prevent sparking of an electric wire.
[0006] The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] Referring first to FIG. 1, there is an assembly view of a wireless power switch control device in accordance with one embodiment of the present invention. The wireless power switch control device comprises: a detection and transmission circuit 1; and receiving and control circuit 2.
[0011] Wherein, the detection and transmission circuit 1 is positioned on an object 3 such as a Christmas tree, a building, or the like for detecting an obliquity of the object 3. A plurality of lamps 32 also positioned on the object 3 for providing light in various color and patterns. The lamps 32 are connected each other in sequence by a wire and then connected to the receiving and control circuit 2 via an electric wire 31. Upon the obliquity of the object 3 reaching to a specified level (for example 30 degree, or the like), the detection and transmission circuit 1 transmits a wireless signal to the receiving and control circuit 2, upon receiving the wireless signal the receiving and control circuit turns off a power of a outlet (shown in FIG. 3) so as to prevent sparking of an electric wire 31.
[0012] Referring to FIG. 2 is a block diagram of a detection and transmission circuit in accordance with one embodiment of the present invention. The detection and transmission circuit 1 further comprising: an obliquity switch 11; a controller 12; and a wireless transmission module 13.
[0013] Wherein, the obliquity switch 11 is placed in the object 3 for detecting the obliquity of the object 3. According to one embodiment of the present invention, the obliquity switch 11 further comprising two conductive plates (not shown) and a metal ball (not shown), upon the obliquity of the object 3 reaching to a specified level (for example 30 degree, or the like), the metal ball leaved form one of the conductive plates so as to make the obliquity switch 11 becoming a open circuit state. Wherein, the controller 12 coupled to the obliquity switch 11, upon the obliquity of the object 3 reaching to a specified level generates a first control signal; and the wireless transmission module 13 coupled to the controller 12, upon receiving the first control signal from the controller 12 transmits the wireless signal, wherein the wireless signal is for example but not limit to a radio frequency (RF) signal or a infrared (IR) signal and the wireless transmission module 13 is for example but not limit to a radio frequency (RF) module or a infrared (IR) module.
[0014] Referring to FIG. 3 is a block diagram of a receiving and control circuit in accordance with one embodiment of the present invention. The receiving and control circuit 2 that is placed closely to the power source further comprises: a wireless receiving module 21; a controller 22; and a power control circuit 23.
[0015] Wherein, the wireless receiving module 21 upon receiving the wireless signal from the detection and transmission circuit 13 will recover the wireless signal into a second control signal; the controller 22 coupled to the wireless receiving module 21, upon receiving the second control signal will generate a turn off control signal, the wireless receiving module 21 is for example but not limit to a radio frequency (RF) module or a infrared (IR) module; and the power control circuit 23 coupled to the controller 22 comprising at least one outlet 231, upon receiving the turn off control signal will turn off the power of the outlet 231, therefore, the sparking of the electric wire 31 will not arise.
[0016] While the invention has been described with reference to a preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
