The present invention relates to an electric toothbrush, which has three bristles for different movements in the head of the toothbrush, characterized in that three surfaces of the tooth can be wiped at once. There are many ways to brush your teeth, but not many people know how to do it. Manual toothbrushes will be the most used, and nowadays electric toothbrushes are known and widely used. Manual toothbrushes, if not properly trained and trained, can cause plaque or foods to be removed from the plaque, resulting in tartar, and can cause tooth wear and gum damage due to misuse. Therefore, when the manual toothbrush is not managed well, using an electric toothbrush is considered to be a much more effective oral care. The type of electric toothbrushes on the market so far has evolved more than in the past and seems to be putting a lot of effort into making effective brushing. However, if you look at the current type of electric toothbrush that is popularly used, there is one bristle or one bristle is attached to one of the head of the toothbrush, which acts only on one side of the tooth remains unfortunate. Of course, the toothbrush of the type that can simultaneously wipe the three sides of the tooth has been developed and registered as a Korean patent or utility model.

The electric toothbrush of Republic of Korea Patent No. 10-0467004 is designed to wipe the three sides of the tooth at the same time because the three rotating rolls are attached to the toothbrush head, but it will work for the teeth arranged in a line, canine It is considered that there is a limit that the inside of the bent portion may not be wiped well and may not be completely wiped by the action of the roll which rotates to the concave deep portion of the occlusal surface. In addition, the size of the tooth is different from the size of the molar, premolar, canine, anterior teeth, because it must be fixed while maintaining a fixed interval, in the case of narrow teeth such as anterior teeth may have the inconvenience of alternately wiping one by one.

Republic of Korea Registered Room No. 20-0378716 is a toothbrush designed to clean the three sides, but there is a limit to the manual and also to maintain a fixed bristle interval.

The present invention is to solve these limitations, to install three bristles of different movements that can simultaneously wipe the three sides of the tooth and to freely adjust the bristle intervals according to the shape and size of the teeth, and bristles By placing them in different sizes, they can be attached and used according to the situation for effective oral care. When describing the three bristles, first, the brush head for wiping the occlusal surface is designed to fit the concave and deep shape of the occlusal surface, so that the concave surface of the occlusal surface can be wiped through a straight reciprocating motion, and the narrowing surface brush head performs a rotary motion. While cleaning the tooth surface, the buccal bristle moves to the center according to the size of the tooth so that the narrow tooth surface can be cleaned while adjusting the gap. The spacing of the narrowed bristles can be controlled by the buttons on the toothbrush handles, and is made possible by the action of gears and shafts separate from the drive motor and the drive shaft. In addition, the brush head for wiping the occlusal surface was removed, and the brush for brushing the tongue was attached to the position so that the tongue could be managed by electric or manual after brushing the teeth.

In order to carry out different actions simultaneously at the same time, a drive motor powered by a rechargeable battery was made possible by operating the gears in the toothbrush head via the drive shaft. The occlusal bristle is operated by converting the rotational force of the center gear, which is driven from the gear attached to the drive shaft, into a linear reciprocating motion, and the narrowing surface bristle is a function of the gear and shaft which transmits the rotational force of the center gear to the gear that rotates the bristle. It worked. The spacing of the stencil bristle is independent of the drive motor, allowing the knobs of the knobs to transmit power to both sides of the stenosis, allowing the two gears to rotate while allowing additional gears and shafts to transmit.

Another feature of the present invention is that the toothbrush handle and the toothbrush neck detachable to add the convenience of storage and portability, one toothbrush handle is more economical that can be used together with the whole family to prepare their own toothbrush head It was.
