Abstract

The invention discloses a power adapter capable of eliminating electromagnetic radiation. The power adapter is characterized in that an alternating current power supply plug 2, a power supply converter 3 and a direct current power line 4 are electrically connected; one end of an electromagnetic radiation coupler 5 is electrically connected with a zero line of the AC power plug 2 at the input end of the power supply converter 3, the other end is electrically connected with the DC power line 4 at the output end of the power supply converter 3, one end of the display XS in an electromagnetic radiation detector 6 is electrically connected with the DC power line 4, and the other end is electrically connected with a touch sheet CM. When a hand touches a touch sheet CM in the electromagnetic radiation detector 6, the electromagnetic radiation detector 6 emits electromagnetic radiation. If the display XS displays, the alternating current power supply plug 2 is transposed and plugged into a power supply, electromagnetic radiation in the direct current power line 4 at the output end of the power supply converter 3 can be coupled into a zero line of the alternating current power supply plug 2through the electromagnetic radiation coupler 5 to be eliminated, and finally the electromagnetic radiation in external electrical equipment is eliminated through the electromagnetic radiation eliminating device.

Description

technical field [0001] The invention relates to the field of low-voltage power supplies, in particular to a power adapter capable of eliminating electromagnetic radiation. Background technique [0002] Electric household appliances will produce electromagnetic radiation, and long-term exposure to electromagnetic radiation will cause certain harm to people. Therefore, eliminating electromagnetic radiation in household appliances is necessary for health and desired by everyone. [0003] It has been proved by market research and patent retrieval that there is no power adapter that can eliminate electromagnetic radiation from external electrical equipment through a power supply. Contents of the invention [0004] In order to solve the problem of home appliance radiation, the present invention provides a power adapter capable of eliminating electromagnetic radiation. This technical solution is not only simple in method and low in cost, but also can effectively eliminate electro...
