Estimating the term…
Disclosed in the present invention are an antibacterial electric toothbrush based on a pulsed ultrasonic piezoelectric response principle, and an antibacterial method. The electric toothbrush in the present invention comprises a toothbrush head and a driving mechanism for driving the toothbrush head to vibrate, wherein the driving mechanism is configured to generate low-intensity pulsed ultrasonic waves, and the toothbrush head is provided with piezoelectric bristles and enhances the electric responsiveness of the piezoelectric bristles by means of ultrasonic vibration, such that a good antibacterial effect is achieved. The provided electric toothbrush can not only effectively inhibit the growth of bacteria on a standing toothbrush head, but also has improved antibacterial activity during a tooth-brushing operation process, such that dental plaque can be effectively inhibited, and oral diseases, such as periodontitis, can be effectively prevented.
