Title:
CURRENT CIRCULATION DETECTION TYPE TOOTHBRUSH CONTROL METHOD AND DEVICE, MEDIUM AND ELECTRIC TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2022/121037
Kind Code:
A1
Abstract:
A current circulation detection type toothbrush control method, comprising: upon acquisition of a power-on signal, a motor operating in a weak-vibration mode (S100); acquiring the present current value of the motor, and determining whether the present current value is less than a first preset current value (S200); if the present current value is less than the first preset current value, controlling the motor to operate in a strong-vibration mode, or the motor continuing to operate in the weak-vibration mode (S300); and when the motor operates in the strong-vibration mode, continuing to acquire the present current value of the motor, and determining whether the present current value is less than a second preset current value (S400); if the present current value is less than the second preset current value, the motor continuing to operate in the strong-vibration mode, or controlling the motor to operate in the weak-vibration mode (S500). By acquiring the working current of the motor, a corresponding sensor does not need to be provided, which reduces the costs, and the overall structure is simple and is easy to implement.
