Tuft toothbrush

    Currently available toothbrushes include triangular tufts, angle cuts, saddle-shaped, dome-shaped, wedge-shaped, ultra-fine taper cuts, bundle tufts, etc. It does not fit to the degree of indentation or the error of each part of the interdental part.

If it always hits the tooth that is the point of action at a right angle, the force of the part that becomes the point of power hits the tooth with maximum efficiency, and plaque and tartar can be easily removed.

The various problems described in (0003) cannot solve the following problems.
In other words, since the triangular tuft is cut into triangles, it cannot be inserted into the back of the interdental portion, and the tip of the hair only hits the point on the back of the incisor, the efficiency is low, and the hair opens quickly without a waist. It is likely that it will fall between the cut teeth, but this interval is rarely suitable for every dentition. The saddle-shaped central part is too gentle in the valley of the occlusal surface, so it does not fit. The wedge shape is also difficult to enter into the meandering groove meandering, and it seems easy to enter into the wire being corrected, but it is difficult to detect the part of the joint of the tooth because it cannot be detected. Flat and round processing is difficult to fit on the concave surface of the occlusal surface. The ultra-fine taper cut looks narrow and easy to enter into grooves and dents, but it is difficult to concentrate in one place because the hairs are scattered and the back of the periodontal groove or incisor does not necessarily have a strong back. A bunch of tufts hits to some extent, but it has the disadvantage that it does not sit down and opens quickly.

A flat bunch at the center and a slope like a gentle skirt from the four sides to reinforce the structure around it, resulting in a Mt. The tip of the hair is fitted with a pitat, and it becomes difficult for the bundle to fall down and open easily with the support of the flocks that make up the surrounding skirt, making it possible to bring out an efficient brushing effect.

Using the principle of eggplant, the brush with the Mt.Fuji brush implanted in the shape of the Mt.Fuji bristles in the shape of the indentations and interdentations on the back of the teeth, and indentation during dynamic movement. It is easy to fit tightly on the bottom and the edge of the tube, and also moves from the deep part of the interdental part to the entrance. The stopper (6) provided at the other end of the handle (3) is used as a fulcrum (8) of the rotating shaft so that the hand force applied to (7) can freely rotate under the cylinder (5). It was applied to a rotatable toothbrush with a structure that freely rotates and stops.

By this invention, it is possible to surely capture the dents and interdental spaces on the back of the teeth, and the extraordinary cleaning effect is achieved by the extraordinary force and sustainability of the hair tip. By applying to the above-mentioned rotatable toothbrush, it can be applied at a right angle, and plaque and tartar can be easily removed under maximum efficiency.

Mt. Fuji toothbrush described in 0006

A rotating toothbrush with a basic structure that maximizes efficiency by always hitting the object at right angles, as in the embodiment where the Mt. Fuji cut brush is applied to a rotating toothbrush.

This principle ensures that the brush always strikes the back of the teeth and the interdental area at a right angle.

Claims (2)

  A flat mountain bundle at the center is the top, and a slant like a skirt is provided on the four sides to reinforce the structure around it. A rectangular shape that fits the narrow shape of the teeth and interdental parts, and does not prevent the top hair tips from fitting to the narrow shapes of various teeth or interdental parts by the inclination of the brush that forms the skirt. A toothbrush with a rectangular size that makes it easier to hit the width and width of the part and easily enter the interdental and periodontal grooves   The toothbrush according to claim 1, wherein the handle to which the brush is applied is applied to the brush using the lever principle, the point held by the hand is used as the power point, and the other end of the handle is used as the rotating shaft. A rotatable toothbrush that is provided with a stopper serving as a fulcrum and has the maximum efficiency when it hits the object at a right angle so that the effect of the brush of claim 1 can be maximized.
