MOUTH CLEANING DEVICE

摘要

PROBLEM TO BE SOLVED: To make an effective current flow to a human body and to improve safety as well. SOLUTION: The mouth cleaning device includes a head portion 1 provided with a brush to be put into the mouth of a human body and a grip portion 2 for holding, the head portion 1 and the grip portion 2 are respectively provided with electrodes 13 and 23 and a voltage is applied between both electrodes. The mouth cleaning device includes a boosting circuit 3 for boosting an output voltage of a battery serving as a power source and applying it between the electrodes and a current limit circuit 4 for limiting a current flowing from one electrode to the other electrode via the human body. A voltage which is higher than a battery voltage and is capable of making a desired current flow is obtained by the boosting circuit, and a surge current is prevented and overflowing of a current is also prevented despite individual differences in a resistance value by the current limit circuit.
