When the pressure value is 300gf, the central processing module 102 obtains the prompt note sequence for reminding. Specifically, the central processing module 102 may further obtain a time corresponding to the pressure, for example, when the pressure value is 300gf and the time for maintaining 300gf is shorter (less than the first preset time), and add a cue note sequence to the preset brushing audio sequence to remind the user that the brushing pressure is too high at this time; when the pressure value is 300gf and the duration of maintaining 300gf is longer (greater than or equal to the first preset time), the central processing module 102 only obtains the cue note sequence for cue, and the cue note sequence is a strong prompt and rapid sound. In addition, the motor 103 may stop vibrating when the pressure value exceeds 200gf and the time is long to prevent the excessive pressure from damaging the teeth.
