A power control device includes an electric power switch and a control unit. The control unit is mounted on an electric device, determines whether the electric device is disposed at a normal use position or an abnormal inclined position, and determines whether the electric device is at a normal use state and is disposed at the normal use position. The control unit controls the electric power switch to provide electric power to the electric device when the electric device is at the normal use state, and to stop providing the electric power to the electric device when the electric device is at the abnormal inclined position.

1. A power control device with multi-directional sensing ability for controlling electricity supply to an electric device, said power control device comprising: an electric power switch for receiving an electric power, and being operable to provide the electric power to the electric device; and a control unit that includes a multi-directional sensor switch configured to be mounted on the electric device, and being operable to determine whether the electric device is disposed at one of a normal use position and an abnormal inclined position, to determine whether the electric device is at a normal use state when the electric device is disposed at the normal use position, to output a power-supply signal when the electric device is at the normal use state, and to output a power-off signal when the electric device is disposed at the abnormal inclined position, anda control circuit electrically connected to said multi-directional sensor switch for receiving the power-supply signal and the power-off signal, and operable to control said electric power switch to provide the electric power to the electric device in response to receipt of the power-supply signal and to control said electric power switch to stop providing the electric power according to the power-off signal;wherein said multi-directional sensor switch is further operable to determine whether the electric device is disposed at a standby position, and to output a standby signal when the electric device is disposed at the standby position, wherein said control circuit further controls said electric power switch to stop providing the electric power to the electric device when said control circuit continuously receives the standby signal for a first predetermined time period; andwherein said multi-directional sensor switch outputs the power-off signal when the electric device is inclined from the standby position, backward beyond a first predetermined angle or frontward to the normal use position beyond a second predetermined angle. 2. The power control device as claimed in claim 1, wherein said multi-directional sensor switch is operable to determine that the electric device is at the normal use state when the electric device is disposed at the normal use position and is moved to and fro, and to output different first and second signals alternately as the power-supply signal in response to reciprocating movement of the electric device, and wherein said control circuit is operable to control said electric power switch to provide the electric power to the electric device when said control circuit receives the first and second signals alternately within a predetermined time period. 3. The power control device as claimed in claim 2, wherein said multi-directional sensor switch is operable to determine that the electric device is at the normal use state when the electric device is disposed at the normal use position without movement, and to output one of the first and second signals as the power-supply signal. 4. The power control device as claimed in claim 1, wherein said control circuit controls said electric power switch to stop providing the electric power to the electric device when said control circuit continuously receives the power-off signal for a second predetermined time period that is shorter than the first predetermined time period. 5. The power control device as claimed in claim 4, wherein said control circuit includes a timer for timing continuous receipt of one of the standby signal and the power-off signal. 6. The power control device as claimed in claim 5, wherein, when said control circuit receives another one of the standby signal and the power-off signal, said timer is operable to restart timing continuous receipt of said another one of the standby signal and the power-off signal. 7. The power control device as claimed in claim 1, wherein the first predetermined angle ranges from 0° to 80°. 8. The power control device as claimed in claim 1, wherein the second predetermined angle ranges from 70° to 110°. 9. The power control device as claimed in claim 1, wherein said control circuit is operable to control said electric power switch according to a user input of a switch signal. 10. The power control device as claimed in claim 1, wherein said control circuit is operable to control said electric power switch according to a signal generated by a sensor. 11. The power control device as claimed in claim 10, wherein the sensor is one of a thermometer, a hygrometer, an illuminometer, a vibration meter, and a smoke detector. 12. The power control device as claimed in claim 1, further comprising a power unit for receiving external power and for converting the external power into the electric power, said power unit being electrically connected to said control circuit and said electric power switch to provide the electric power thereto. 13. The power control device as claimed in claim 1, wherein said control circuit includes a safety module, and is operable to actuate said safety module for disabling said electric power switch for providing the electric power to the electric device according to the power-off signal, and to disable said safety module for enabling said electric power switch to provide the electric power to the electric device upon receipt of a user input of a switch signal.
