速い速度で回転し、ブラシ体が速い速度で運動するため
、弱く磨くことができない。Since the rotational speed of the motor is fixed, if the brush body is strongly pressed against the teeth, the load on the motor increases, the rotational speed of the motor decreases, and the reciprocating speed of the brush body decreases. Therefore, for example, when the brush body is strongly pressed against the teeth in an attempt to strongly brush the teeth, the movement speed of the brush body decreases and it is not possible to brush the teeth strongly. On the other hand, if you apply the brush body lightly to the teeth in order to gently brush the teeth, the load on the motor is small, the motor rotates at a high speed under light load, and the brush body moves at a high speed. It is weak and cannot be polished.

As the number increases, the rotational speed of the motor 4 is controlled to become faster, which is convenient when you want to brush your teeth vigorously. Also, lightly touch the brush body 7 to your teeth, and
When the pressure applied to the brush is reduced, the rotational speed of the motor 4 is controlled to be slow, which is convenient when you want to gently brush your teeth.

As shown in FIG. 5(b), if you forcefully press the brush body 7 against your teeth, the rotational speed of the motor 4 will slow down, which is convenient when you want to brush thoroughly without damaging your gums. When the body 7 is lightly applied to the teeth, the rotational speed of the motor 4 increases, which is convenient when you want to brush your teeth quickly.

The speed control circuit 13 to which the signal is input is shown in FIG.
As shown by the solid line in C), a correspondence relationship is selected that provides a constant rotational speed suitable for standard tooth brushing regardless of the pressure.
そのため、常に適度な速さで磨くことができて、便利で
