The invention relates to an intelligent toothbrush control circuit. At present, the vibration speed and received ultrasonic frequency of bristles of commercially-available electric toothbrushes are limited by the set values of a three-gear switch. The intelligent toothbrush control circuit provided by the invention is based on the conventional control technology of conventional three-gear switches, can randomly adjust the vibration speed of bristles and the output frequency of an ultrasonic motor in the process of tooth brushing via the handholding pressure of a toothbrush handle, protects gingivae from hurt in the process of tooth brushing, and achieves the purpose of intelligent tooth brushing. 本发明涉及种智能牙刷控制电路，目前市场在售的电动牙刷刷毛振动速度和接收的超声波频率大小受限于设定的三档位开关值。本发明智能牙刷控制电路在原有的三档位开关的控制技术上，通过手握牙刷刷柄的压力大小实现刷牙过程中随意调节刷毛的振动速度和超声波电机输出的频率，避免刷牙过程中伤及牙龈，达到智能刷牙的目的。
