Abstract:
1. An oral cavity cleaning tool comprising: a block handle; a head section including brushing bristles, said head section extending from said block handle; at least a pair of electrodes provided on said head section, said electrodes being embedded in an outer surface of said head section and a distance between said electrodes being in a range of 1 mm to 20 mm; a power source that supplies electric current to said electrodes by keeping them at different potentials such that current flowing between said electrodes transforms chloride ions in an oral fluid into effective chlorine when placed into contact with the oral fluid; and a constant current circuit connected with said power source, said constant current circuit maintaining a rate of current sufficient to keep constant the generation of the effective chlorine, a resistance of said constant current circuit being in a range from 750 Ωto 4500 kΩ and said current between said electrodes being in a range from 50 μA to 2 mA.
