Embodiment Construction

[0018] see figure 1 , the electronic device 100 according to the embodiment of the present invention includes a power supply plug mechanism 10 , a circuit board 40 and a casing 50 . The circuit board 40 is accommodated in the case 50 . The power supply plug mechanism 10 is partially housed in the casing 50 and partially protrudes from the casing 50 , and the power supply plug mechanism 10 is installed on the circuit board 40 and is electrically connected to the circuit board 40 . The current output by the power supply (not shown) flows into the power supply plug mechanism 10 , and then supplies power to the circuit board 40 to make the electronic device 100 work, and the power supply plug mechanism 10 can control the power supply on and off. The electronic device 100 in this embodiment is a digital video conversion box. It can be understood that the electronic device 100 can also be other home appliances or electronic products, such as a cable modem.

Abstract

An electronic device comprises a power supply plug-in mechanism. The power supply plug-in mechanism comprises a switch assembly and a connector. The switch assembly comprises a gear transmission shaft, an elastic piece, a first transmission wheel, a second transmission wheel, a key gear and a key, wherein the key and the key gear are fixedly connected; the key gear and the first transmission wheel are engaged; the second transmission wheel and the first transmission wheel are fixedly connected; the gear transmission shaft sequentially passes through the elastic piece, the first transmission wheel and the second transmission wheel. The connector is provided with a slot, and the second transmission wheel is partially accommodated in the slot. The invention also provides a power adapter matched with the power supply plug-in mechanism. The power adapter comprises a rotary switch and a second transmission belt sleeving the rotary switch. A user presses the key to sequentially drive the key gear, the first transmission wheel, the second transmission wheel and the second transmission belt, and the rotary switch is thus opened and closed. The electronic device of the invention is convenient in operation, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to an electronic device, in particular to an energy-saving electronic device and a power adapter used in conjunction with it. Background technique [0002] Most of the small and medium-sized household appliances and electronic products provide the power required by an external power adapter. The power adapter is plugged into the power socket through the input plug, and the output plug on the power adapter is inserted into the slot of the electronic product. After the input plug, the power adapter, and the output plug, it is finally connected to the electronic product, and the electronic product then works. General household power sockets are usually hidden in corners or other places that are not easy to reach. Therefore, when people stop using electronic products, people usually choose to let the products stand by. However, the products still consume part of the power when they are in standby. In order to solve the problem of sta...
