JPH10118100A - Rotational motor-driven tooth brush - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reasonably brush teeth by hooking a large-sized gear on the rotational shaft on a gear fitted to the shaft of a small-sized motor with a battery as an electric source and providing a brush on the apex part of the rotational shaft and arranging a battery in one end part of the motor-driven brush and a bearing part on another end part. SOLUTION: A small-sized gear is fitted on the shaft 2 of a small-sized motor 1 and a large-sized gear on the rotational shaft 6 is hooked on this gear and a brush 7 is provided on the apex part of the rotational shaft 6 to prepare a motor-driven brush. In addition, a battery C is provided in one end part of the motor-driven brush and a bearing part 8 is provided in the brush main body A on another end part. When this is used, a grasping part 2 is grasped by one hand and tooth paste is placed on the brush 7 and a switch is turned on and the brush 7 is brought into contact with the teeth to brush the teeth. As the brush can be freely rotated in regular rotation and in reverse rotation, it is possible to uniformly brush the whole teeth and to cleanly brush every corner of the teeth and to simply replace.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary electric toothbrush capable of brushing teeth rationally by rotating the brush forward and backward.

[0002]

2. Description of the Related Art Conventionally, when brushing teeth, one has to grip the handle of a toothbrush with one hand, apply the brush to the surface of the tooth, and move the brush up, down, left and right. In recent years, electric toothbrushes have been provided, which can be brushed by vibrating the brush.

[0003]

However, these toothbrushes have the following disadvantages. I. He moved his toothbrush by hand, so he could brush well in the horizontal direction, but not in the vertical direction. B. Therefore, it has not been possible to clean the gap between the teeth and the back side of the teeth. An object of the present invention is to provide a toothbrush that can rationally brush its teeth by rotating the toothbrush forward and backward with a small motor.

[0004]

According to the present invention, a small gear 3 is mounted on the tip of a shaft 2 of a small motor C powered by a battery, and a large gear engaged with the gear 3 is provided. A rotating shaft 6 is provided via a gear 4, and an electric brush having a brush 7 provided at the tip of the rotating shaft 6 is provided with a battery C in one end.
And provided inside the brush body A provided with the bearing 8 at the other end.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION When the present invention configured as described above is actually used, the following is performed. Holding part B with one hand
After brushing the brush 7 and brushing the brush 7, the switch 9 is turned on to rotate the brush 7, and the brush 7 is applied to the teeth. The switch 7 can rotate the brush forward and backward, so that the rotation of the brush 7 can be freely changed as necessary. The rotating shaft 6 is connected by the connecting portion 10 so that the brush 7 Can be easily replaced.

[0006]

Embodiments of the present invention will be described below. The present invention uses a battery as a power source, and performs a unique and rational tooth brushing by rotating and reversely rotating a brush using the power source. A small gear is mounted on the shaft 2 of the small motor 1, A rotary shaft 6 is provided via a large gear engaged with this gear, an electric brush having a brush 7 provided at the tip of the rotary shaft 6, a battery C provided in one end, and a bearing 8 provided at the other end.
This is provided inside the brush body A provided with a brush. When the brush is actually used, the grip portion 2 is gripped with one hand and the brush 7 is
The brush can be brushed easily by brushing the tooth with the switch 9 and brush 9 on the tooth.

[0007]

As described above, the brush can freely rotate forward and reverse, so that the entire tooth can be uniformly and thoroughly brushed to the corners of the tooth, and can be easily replaced.
