A plurality of engaging jaw 126A is formed to protrude.

1 to 4, the bristles 123 are planted in the head portion 121 of the toothbrush rod 120, and the material is polyethylene terephthalate (PET) or polybutylene terephthalate (Polybutylene telephthalate). PBT). Here, the reason for not using nylon as the material of the bristles 123, and PET or PBT is a disadvantage in that the nylon is strongly absorbent and the flexible mock form is quickly deformed by use. In addition, nylon has a short lifespan and is not suitable for giving softness because the thickness must be maintained to some extent in order to maintain a constant elasticity.

As such, the bristles 123 having a material of PET or PBT are shown in FIG. 4, and tapered portions 124 are formed at both ends thereof, and both ends thereof are positioned on the same line when the center is folded. The length of the tapered portion 124 of the bristles 123 is preferably 4 to 7 mm. If the length of the tapered portion 124 is less than 4 to 7 mm, the hardness may be excessive and the gums may be damaged when brushing. If the length of the tapered portion 124 exceeds 4 to 7 mm, the tapered portion 124 may have insufficient hardness. You feel lacking.

The diameter of the tip of the taper part 124 is 0.01-0.07 mm, More preferably, it is 0.01-0.03 mm.

The drive motor 130 is a motor capable of forward and reverse rotation, and is installed at one side of the storage chamber 102 of the case 100 to control the operation according to the selective operation of the operation switch 110. An eccentric vibrating element 136 is formed on the motor shaft 132 of the driving motor 130.

The vibrating element 136 is mounted in an eccentric state with respect to the motor shaft 132. Accordingly, the rotation of the driving motor 130 causes the eccentric rotation of the center of gravity to vibrate. The vibration generated by the vibrating element 136 vibrates the drive motor 130 itself so that the case 100 and the toothbrush rod 120 vibrate.

Here, the frequency generated by the rotation of the vibrating element 136 causes 20,000 to 27,000 vibrations per minute. The vibration frequency of 20,000 to 27,000 vibrations per minute is a range in which the effect of the sound wave region can be obtained. If the frequency is lower than the frequency of the sound wave region, it gives a feeling of electric shock and gives a discomfort to the user. In addition, if the frequency is higher than the frequency of the sound wave region, it is necessary to use the ultrasonic region, and therefore expensive driving motors (for example, linear motors or inverted motors) and ultrasonic vibration elements. This may cause discomfort to the user such as injury. Therefore, it is preferable to use a sound wave region in which the frequency is not low or high every minute.

The battery 140 is installed at the other side of the storage chamber 102 and is connected to the driving motor 130 to supply power. One or two batteries 140 may be stored and used according to the size of the case 100.
