Toothbrush |
摘要 |
An electrically operated toothbrush comprises a housing with an electromotor inside the housing. The motor includes a rotatable shaft, means converting the rotary movement of the rotary shaft to an oscillatory movement of a brush support shaft which extends through the housing, and a toothbrush is attached to the free end of the support shaft outside of the housing. Sensing structure generates an impulse representative of the pressure exerted on the toothbrush during toothbrushing. A microprocessor or electronic device receives the impulses from the sensing structure during toothbrushing and compares those impulses with stored information representative of a predetermined optimum pressure range for toothbrushing. A signal transmittor releases a signal perceptible by the user of the toothbrush when the pressure on the toothbrush exceeds the predetermined optimum pressure range.
