As a preferable scheme of the invention, the electrolyte unit is a vitamin C aqueous solution, the positive and negative voltage switching circuit ionizes the vitamin C aqueous solution to generate positive and negative ions, and the positive and negative ions are led into the skin along with the contact of the electrode unit and the skin of a human body to form a closed circuit to carry out metabolic waste in the skin, thereby achieving the effect of beautifying.
As a preferable aspect of the present invention, the electrode unit includes a positive electrode metal piece and a negative electrode metal piece, which are connected to the negative electrode and the positive electrode of the electrolyte unit, respectively.
As a preferable scheme of the invention, the MCU control circuit comprises a DC/DC booster circuit, and is used for adjusting the voltage and the current fed back by the skin to the direct current voltage required by a proper positive and negative ion driving circuit through a dynamic current digital adjusting circuit and a dynamic voltage digital adjusting circuit.
The beneficial effect of adopting above-mentioned technical scheme is: the skin care electrolyte is firstly electrolyzed into positive ions and negative ions through a power supply circuit, then ions of active ingredients of the electrolyte are introduced into the deep layer of the skin through the repulsion among particles with the same charges, the introduced substance is a negative ion with negative electrons and is introduced by a negative electrode metal sheet, otherwise, the derived substance is a positive ion with positive electrons and is led out by a positive electrode metal sheet; because everyone's sign is different, it can also be different from skin feedback voltage electric current size, the DC/DC boost circuit that MCU control circuit includes for adjust the required direct current voltage of a suitable positive and negative ion drive circuit through dynamic current digital control circuit and dynamic voltage digital control circuit with the voltage electric current that skin feedback comes, thereby avoided the loss grow of internal circuit, the electrode sheetmetal generates heat and seriously burns skin, the damage of internal drive circuit, generate heat and even cause the danger of catching fire.
