Stain etc..Electric current can be produced during motor oscillating；By substantial amounts of actual data analysis, user is brushed teeth during brushing teeth
Dynamics is different, and the electric current that its motor produces also can be different, that is, the electric current of the more big so generation of the dynamics brushed teeth also can become accordingly
Greatly；Through scientist's experiment, when adult brushes teeth, brushing force controls in 0.9 newton -1.4 newton (note:1 newton is equal to 0.102 kilogram
Power), that is,：Adult's brushing force controls in 100-150 gram force, both effectively can dispel dental plaque, and not injure gingiva, thus reach cleaning one's teeth
The effect of shield gum.Therefore by result of study above, the current value of our motors in 150 gram force using brush dynamics as
We judge the whether normal standard of brush dynamics.It is correct that the current of electric detecting is less than or equal to during this standard value
Brush dynamics；And if electric current is more than this standard value, it is judged as that brush dynamics are excessive.
Detected the electric current of now motor by controller 1, and just whether this current value then judge brush dynamics as us
Normal standard.When brushing teeth, our controller 1 can detect the size of now current of electric to user in real time, when detecting
Electric current now is less than or equal to during standard value it is believed that being now correct brush dynamics, does not do any action；Work as detection
Electric current when being more than standard value, then controller 1 will be lighted red LED and makes its Chang Liang always by feeding back indicating circuit, announcement
Tell that your dynamics brushed teeth of user is excessive, should timely correct, until detect current value be less than or equal to red during standard value
LED just can extinguish, and represents that the brush dynamics of user are correct.
