Abstract
An electric field generating device for oral care of the present invention includes: at least one electrode configured to receive a driving signal and generate an electric field corresponding to the driving signal; and a signal supply part configured to generate the driving signal by mixing an AC signal and a DC signal and supply the driving signal to an electrode.
Claims13
An electric field generating device for oral care, comprising:
- at least one electrode configured to receive a driving signal and generate an electric field corresponding to the driving signal;
- and
- a signal supply part configured to generate the driving signal by mixing an alternating current (AC) signal and a direct current (DC) signal and supply the driving signal to the at least one electrode,
- wherein the signal supply part includes:
- a DC-DC converter configured to receive a battery voltage and convert the battery voltage into an output voltage;
- a signal generator configured to generate the AC signal using the output voltage of the DC-DC converter;
- a filter configured to perform a filtering operation on the AC signal generated by the signal generator;
- and
- a calibration part, including an amplifier, configured to generate the driving signal by mixing the DC signal with the AC signal supplied through the filter.
