Abstract

The invention discloses a power supply device capable of eliminating electromagnetic radiation of household appliances, which is characterized in that an alternating-current power line 2, a power converter 3 and a direct-current power line 4 are electrically connected, one end of an electric radiation coupler 5 is electrically connected with an alternating-current power supply zero line at the input end of the power converter 3, and the other end is electrically connected with a direct-current power supply at the output end of the power converter 3; and the end A of the electric radiation detector 6 is electrically connected with an alternating-current power supply zero line at the input end of the power converter 3. When a hand touches a touch sheet in the electric radiation detector 6, if a display in the electric radiation detector 6 is on, the plug of the power line 2 is transposed and plugged into a power supply, so that electromagnetic radiation generated in the direct-current power line 4 can be coupled to a zero line of the alternating-current power line 2 through the electric radiation coupler 5 to be eliminated; finally, the purpose of eliminating electromagnetic radiation of external household appliances is achieved through the device.

Description

technical field [0001] The invention relates to the field of low-voltage power supplies, in particular to a power supply device capable of eliminating electromagnetic radiation of household appliances. 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 is proved by market research and patent retrieval that there is no power supply device that can eliminate the electromagnetic radiation of external household appliances through the power supply. Contents of the invention [0004] In order to solve the radiation problem of household appliances, the present invention provides a power supply device capable of eliminating electromagnetic radiation of household appliances. This technical solution is not only simple...
