It is well known that there is an electric toothbrush described in SQ6 publication, and that some are commercially available.

りブラシを上下運動する本のであった。As shown in the above-mentioned publication, these electric toothbrushes convert the rotational force of the motor into a swinging motion and transmit it to the toothbrush rod, causing the brush body to reversely swing at high speed. It was a book that uses a so-called vibrator to move the brush up and down.

の内側がＦＩＩきにくめ欠点がある。Problems to be Solved by the Invention The above-mentioned conventional electric toothbrushes use a mechanism that converts the rotational motion of the motor shaft into a oscillating motion to invert or oscillate the toothbrush, which is installed vertically at the tip of the toothbrush rod, at a certain angle. Since teeth were brushed using eccentric weights that vibrated up and down, when the toothbrush rotated toward the root side, the tips of the bristles would scrape the gums and damage the gums, and the bristles of the toothbrush had a concave shape Many of them have a straight cut shape, and when brushing the backside of the teeth, it is difficult to remove plaque from between the teeth or on both sides, and the inside of the teeth is cut into FII, which is a drawback.

When turning to the back, left, or right, the toothbrush rotates in a direction that presses down on the gums in the same way as described above, which has the disadvantage of damaging the gums and the skin inside the mouth.

ある。The present invention was devised in view of the above-mentioned circumstances, and the brush always acts to lift the tooth from the root side to the tooth tip side depending on the position of the tooth being brushed, and also damages the gums and the skin inside the mouth. To provide a self-rotating toothbrush which is safe without fear and which can evenly and neatly brush both the left and right rows of the back side of the teeth.

駆動できるようにするものとする。Function The present invention has the above configuration, and when the changeover switch (6) is turned on after connecting to the battery (2) or power source, the electric shaft (6) and rotating brush (9) of the reversible motor (4) are moved in a predetermined direction. Since the rotating brush (9) rotates to the qth position by holding the first grip (1),
As shown in the figure, when applied to a tooth (A) at a predetermined position, the rotating brush (9) scrubs the tooth from the root side to the tooth tip, and the bristles of this rotating brush have a convex arc shape in the axial direction. (8), it not only makes good contact with the tooth surface, but also allows the tips of the bristles to easily penetrate between the teeth, allowing plaque to be removed well. In addition, at the first stone on the left of the row of teeth, the rotation direction of the electric shaft (6) and rotating brush (9) is changed by operating the changeover switch (6), and therefore the front and back surfaces of the upper and lower teeth and the left and right rows of teeth are changed. When cleaning the teeth, the rotating brush (9) is rotated from the root side toward the tip of the tooth, as described above (both the inner and outer surfaces of the teeth can be brushed evenly and easily without touching the gums). At the same time, a protective cover head is provided on one side of the one-turn brush (9) so as to go over it, so that the one-turn brush (9) can be applied without damaging the skin inside the mouth. To explain the present invention in detail, (1)
is a cylindrical case-shaped grip made of synthetic resin, and contains a battery (2) and a reversible motor 14) that can be used in forward and reverse directions, and the reversible motor (4) is connected to a general household power outlet. It shall also be possible to drive it by plugging in the cord (3).

ｈ。(9) is a rotating brush whose basic shape is a circular shape in which the peripheral surface of the bristles, which are planted in multiple rows radially on the shaft head (7), is formed in a convex arc shape (8) in the axial direction. Most efficient for the shape of loose teeth (designed in a shape that can be polished,
It is attached to the tip of the tm shaft (6) so that it can be replaced freely. It may be possible to set or select several types with different curvatures and brush widths of the convex arc shape 18).

The rotating brush has a convex arc shape in the axial direction and can be replaced freely, and a protective cover is attached to one side of the rotating brush from the grip. The rotating direction can be easily switched, and the rotating brush always rubs from the root side to the tooth tip regardless of the inner or outer surface of the tooth, as well as the left and right rows.Moreover, the circumferential surface of the bristles of the rotating brush has a convex arc. Because of its shaped shape, it not only fits well against the tooth surface, but also makes it easy for the tip of each bristle to reach the 9 spaces between the teeth, allowing it to remove plaque evenly from each part without scratching the gums. Moreover, it is not only possible to brush the gums easily without damaging them, but also to strengthen the gums due to the pine surge effect caused by brushing the gums. Also, since there is a protective cover on one side of the rotating brush, there is no risk of damaging the skin inside the mouth with the rotating brush, making it extremely safe. Furthermore, due to the convex arc shape of the tip of the bristles and the ability to switch the rotation in a direction that does not damage the gums, it is possible to brush the back surfaces of teeth more efficiently than conventional electric toothbrushes. In addition, the rotating brush can be replaced with the electric shaft with one touch.
This has the advantage that it is possible to freely replace the toothbrush with the most suitable one depending on the shape of the toothbrush and individual differences.
