Abstract:
A DC-AC electric potential treatment apparatus comprising:an electric cloth comprising a treatment lead for outputting AC or DC, wherein said treatment lead is covered with a cloth material; an AC power supply; a DC-AC power supply circuit for supplying DC or AC to said treatment lead, said DC-AC power supply circuit including a capacitor for charging an electric voltage and a resistor connected to said capacitor in parallel for discharging said electric voltage charged in said capacitor; a DC-AC switch circuit for switching the supply from said DC-AC power supply circuit to said treatment lead between DC and AC, said switch circuit including a reed relay connected to an output terminal of DC and AC of said DC-AC power supply circuit and a timer; a switch for selecting an output of said treatment lead from DC and AC; a heater for heating said electric cloth and keeping said electric cloth warm; and a power supply circuit for said heater for supplying power supply voltage to said heater, wherein when said switch selects one of DC and AC, the electric current from said AC power supply to said DC-AC power supply circuit is stopped, and said reed relay is closed after a first predetermined time by said timer, then after a second predetermined time the electric current from said AC power supply to said DC-AC power supply circuit is started said selected DC or AC is applied to said treatment lead.
