Voltage self-adaption power circuit capable of shifting gears and using method thereof

Abstract

The invention discloses a voltage self-adaption power circuit capable of shifting gears and a using method thereof. The power circuit comprises a power transformation box. A power transformation cavity is formed inside the power transformation box. An iron core is fixedly arranged inside the power transformation cavity, a medium rate power transformation cavity is formed inside the iron core, a high rate power transformation cavity is formed below the medium rate power transformation cavity, a low rate power transformation cavity is formed below the high rate power transformation cavity, a plugging-in box located at the right side of the iron core is fixedly arranged inside the power transformation cavity, a vertically-symmetric medium rate copper sheet is fixedly arranged inside the plugging-in box, a medium rate jack cavity with a right opening is formed inside the medium rate copper sheet, a high rate copper sheet located below the medium rate copper sheet is fixedly arranged insidethe plugging-in box, and a high rate jack cavity with a right opening is formed inside the high rate copper sheet; the power circuit is simple in structure and convenient to use, the power circuit isimproved and designed for solving the problem that at present, different nations adopt different household appliance voltages internationally, manual adjustment can be performed according to the voltages of the household appliances, the mechanical structure is adopted in the process, and voltage conversion can be completed just by pressing down a button in the process.

Description

technical field [0001] The invention relates to the field of changing the voltage of civil electrical appliances, in particular to a shiftable voltage self-adaptive power supply circuit and a method for using the same. Background technique [0002] Traveling abroad is one of the ways people go on vacation at present, and more and more people choose to travel abroad, but due to different countries, the size of the civilian voltage in each country is also different, people who travel often need to go to the store to buy different transformers In order to meet the needs of travel in different countries, this method is very troublesome, and the transformer with relatively high quality is easy to spontaneously ignite and cause unnecessary losses due to its circuit components. The design of the present invention is proposed for the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a shiftable voltage adaptive power supply circu...
