         [0004]    An electronic appliance with a system capable of automatic power-off refers to an electronic appliance capable of being turned off by a user through an operating system without having to turn off the electronic appliance manually or through remote control, and when the electronic appliance is powered on next time, the user needs to press a switch button to turn on the electronic appliance. When this type of electronic appliance is powered off, the power source is not completely turned off. At this time, the power source power consumption is standby power consumption of the electronic appliance. By eliminating the standby power consumption of this type of electronic appliance, energy resources may be saved, the environment may be protected, and the safety of the electronic appliance may be improved. In an existing device for eliminating standby power consumption of the electronic appliance, a power source input current of the electronic appliance is monitored. When the power source input current decreases below a preset current value, it is regarded that the electronic appliance is already powered off and power supply to the electronic appliance is turned off, so as to eliminate standby power consumption. The device has a turn-on button connected to a body thereof in a wired manner. When a user needs to power on the electronic appliance, the user first presses this button to turn on power supply to the electronic appliance, and then press a switch button of the electronic appliance to turn on the electronic appliance. The defect lies in that different electronic appliances have different standby power consumption and work power consumption, at a preset standby power consumption threshold value, the standby electronic appliance or normally working electronic appliance might be unable to be turned off. When turning on the electronic appliance, the user needs to first press the turn-on button of the device to turn on power supply to the electronic appliance, and then also needs to press the switch button of the electronic appliance to turn on the electronic appliance, such that the operation is complicated and use is convenient.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0034]    The device for eliminating standby power consumption of an electronic appliance with a system capable of automatic power-off in present invention is used for eliminating standby power consumption of an electronic appliance such as a computer. The electronic appliance with a system capable of automatic power-off refers to an electronic appliance such as a computer that can be turned off by a user through an operating system. The user does not need to turn off the electronic appliance manually or through remote control. 
         [0035]    When the electronic appliance is powered on next time, the user needs to turn on the electronic appliance by pressing a switch button. When this type of electronic appliance is powered off, the power source is not completely turned off. At this time, the power source power consumption is the standby power consumption of the electronic appliance. The device for eliminating standby power consumption of the electronic appliance may save energy resources and protect the environment. 
         [0036]    The control switch portion  60  of the device includes a control unit  10 , a wireless signal receiving unit  30 , a control electronic appliance power supply switch unit  40  and a power supply unit  50 . The power-on signal wireless transmitting unit  20  and the control switch portion  60  of the device are connected in a wireless manner. 
         [0037]    The use of the device includes two processes: initial installation and normal use. 
         [0038]    During the initial installation, as shown in  FIG. 5 , a flexible button  21  of the power-on signal wireless transmitting unit  20  capable of being adhered to different surfaces is adhered on the surface of the switch button  74  of the controlled electronic appliance  71 . The power plug  52  of the control switch portion  60  of the device is plugged on the external power source socket  72 . A power input end (power plug)  73  of the controlled electronic appliance  71  is plugged on the power socket for supplying power to a controlled electronic appliance  42  of the device. After the above installation is finished, the setting and work status indicator lamp  15  becomes light red indicating that a power source is turned on. The setting and manual power-on button  14  is pressed and held for several seconds till the setting and work status indicator lamp  15  becomes light blue indicating that the device enters a setting status. At this time, the power-off is performed through the operating system of the controlled electronic appliance. After the electronic appliance is powered off for a few minutes, the controlled electronic appliance power-on/off button  74  is pressed to power on the electronic appliance again. After the electronic appliance is powered on, when the input current of the controlled electronic appliance becomes stable, the setting status is ended. The setting and work status indicator lamp  15  becomes light red. In the setting process, the controlled electronic appliance power consumption current sensor  13  transfers an input current value of the controlled electronic appliance  71  to the control chip  11 . The control chip  11  saves an input current value when the controlled electronic appliance  71  is in a stable power-off status as a standby status current value in the memory  12  for storage. 
         [0039]    During normal use, when the controlled electronic appliance  71  is in a power-on status, the controlled electronic appliance  71  is powered off through an operating system. The controlled electronic appliance power consumption current sensor  13  transfers an input current value of the controlled electronic appliance to the control chip  11 . The control chip  11  compares the input current value of the received controlled electronic appliance with the standby status current value stored in the memory  12 . When the input current value of the controlled electronic appliance becomes stable within a standby status current value range, it is regarded that the controlled electronic appliance  71  already enters a standby status. The controlled electronic appliance power supply switch unit  40  is controlled to turn off the power supply of the controlled electronic appliance  71 . When the controlled electronic appliance  71  is in a power-on status, while the controlled electronic appliance switch button  74  is pressed to power off the electronic appliance, the flexible button  21  adhered to the surface of the switch button is pressed. The power-on signal wireless transmitting unit  20  transmits a wireless power-on signal. The control chip  11  ignores the received wireless power-on signal and waits until the input current value of the controlled electronic appliance transferred from the controlled electronic appliance power consumption current sensor  13  satisfies the standby status, so the control chip  11  starts to control the controlled electronic appliance power supply switch unit  40  to turn off the power supply of the controlled electronic appliance  71 , thereby avoiding that the power source is turned off due to actions by mistake. When the controlled electronic appliance  71  is in a power-on status, the action of pressing the setting and manual power-on button  14  is ignored by the control chip  11  to avoid that the power source is turned off due to actions by mistake. 
         [0040]    When the controlled electronic appliance  71  is in a power-off status, the controlled electronic appliance switch button  74  is pressed to power on the controlled electronic appliance  71 . The switch button  74  needs to be continuously pressed until the controlled electronic appliance is powered on, and the flexible button  21  adhered to the surface of the switch button surface is pressed at the same time. The power-on signal wireless transmitting unit  20  transmits a wireless power-on signal. Upon receiving the wireless power-on signal, the control chip  11  controls the controlled electronic appliance power supply switch unit  40  to turn on the power supply of the controlled electronic appliance  71 . After acquiring the power supply, the controlled electronic appliance  71  is powered on as the switch button  74  is continuously pressed. When the controlled electronic appliance  71  is in a power-off status, the setting and manual switch button  14  is pressed. The control chip  11  controls the controlled electronic appliance power supply switch unit  40  to turn on the power supply to the controlled electronic appliance  71  and waits for the user to power on the controlled electronic appliance  71  by pressing the controlled electronic appliance switch button  74 . After a certain time is waited, if it is not detected that the controlled electronic appliance  71  is powered on, the control chip  11  controls the controlled electronic appliance power supply switch unit  40  to turn off the power supply to the controlled electronic appliance  71 . Therefore, the user can manually power on the controlled electronic appliance  71  when the signal wireless transmitting unit  20  is ineffective or a battery  24  is out of power. Meanwhile, it is avoided that the power source is turned on due to actions by mistake.
