Embodiment Construction
[0019] refer to figure 1 , which is a block diagram of the first embodiment of the electronic device according to the present invention. In the figure, the electronic device 1 is electrically connected to an external power supply device 5 having an on state and an off state, wherein the electronic device 11 includes a switch module 2 , an internal power module 3 and a control module 4 . The switching module 2 generates a switching signal 21 when activated.
[0020] The internal power supply module 3 receives the switch signal 21 , thereby generates a trigger signal 31 and transmits it to the external power supply device 5 , so as to trigger the external power supply device 5 to turn from off state to on state, so as to provide power 51 to the electronic device 1 .
[0021] The control module 4 receives the power supply 51 and the switch signal 21 to generate a control signal 41 and transmit it to the external power supply device 5 to control the state of the external power su...

The invention relates to an electronic device and a method thereof for controlling an external power supply device. The electronic device is electrically connected with the external power supply device with an open state and a closed state and comprises a switch module, an internal power supply module and a limiting module, wherein the switch module generates a switch signal when triggered; and the internal power supply module receives the switch signal to generate a trigger signal to the external power supply device to trigger the external power supply device to switch to the open state from the closed state, therefore the external power supply device provides a power supply for the electronic device. The limiting module is electrically connected between the internal power supply module and the external power supply device and is used for reducing the signal level of a trigger signal.
Description
technical field [0001] The invention relates to an electronic device and a method for controlling an external power supply device, in particular to an electronic device capable of controlling the external power supply device to turn from a closed state to an open state. Background technique [0002] Due to the strengthening of environmental protection awareness, more and more users hope that electronic devices can reduce power consumption, and most electronic devices use power supplies to supply power. cause unnecessary power consumption. [0003] At present, there is a power supply that can be controlled to be turned on or off. However, if the electronic device using the power supply needs power, the user needs to turn on the power supply switch first and then turn on the switch of the electronic device, thus causing operational problems. the inconvenience. Contents of the invention [0004] The present invention is proposed to solve the above problems. The purpose of t...
