As an example, after user opens electric toothbrush, the pressure at least one same time period is successively obtained
Value judges whether at least one pressure value is respectively less than and is equal to first threshold, if so, calculating the average value of at least one pressure value
As pressure zero value, if it is not, then determine that pressure zero value is 0, as electric toothbrush is put on tooth, then the pressure that detects
Force value can become larger, and calculate the pressure increment of current pressure value and the pressure zero value, and judge that the pressure increment is less than
Second threshold and be greater than first threshold when, if, adjusting the electric toothbrush operational mode be slight vibration mode；Work as institute
When stating pressure increment between second threshold and third threshold value, the operational mode for adjusting the electric toothbrush is normal mode of vibration
Formula；When the pressure increment is greater than third threshold value, the operational mode for adjusting the electric toothbrush is low frequency modes.
In conclusion first threshold, second threshold and third threshold value can be set in advance according to user experience,
Value can be with are as follows: first threshold can be 0.1N, and second threshold can be 0.5N, and third threshold value can be 2.0N.
