PLASMA STERILIZER AND PLASMA STERILIZED REFRESHING WATER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a plasma sterilized refreshing water device which is low in impressed voltage, is safe and is mechanically simple. SOLUTION: Coaxial electrodes 2 and 3 are installed in water and the size of the circular core-like electrode 3 on the inner side is made extremely smaller than the size of the cylindrical electrode 2 on the outer side. A power source 1 is connected between the electrodes 2 and 3 to enhance insulation characteristics between the electrodes 2 and 3 and to generate an electric discharge 4 between the electrodes 2 and 3 by a low voltage.
