Description

[Detailed Description of the Invention] The present invention relates to a toothbrush, and more particularly to a toothbrush that can be easily used even by an unskilled person to prevent dental caries and alveolar pyorrhea (cleaning and pine surgery).

Conventional manual toothbrushes require skill to use, and there are individual differences in tooth cleaning and gum surge, and preventative effects cannot be expected.

Electric toothbrushes have also recently been considered, but they have the drawback of producing large vibrations, which are rather unpleasant and can cause more harm than good to unskilled users, such as damaging teeth and gums.

In view of the above-mentioned conventional drawbacks, the present invention aims to provide a toothbrush that can be easily used even by an unskilled person and that can prevent tooth decay and alveolar pyorrhea (cleaning and pine surge).

Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in the drawings.

In the embodiment shown in FIGS. 1 to 5, reference numeral 1 denotes a gripping portion, and a driving device (not shown) such as a motor is built in this gripping portion 1. In the embodiment shown in FIGS. Reference numeral 2 denotes a cylindrical handle portion fixed to the grip portion 1. Reference numeral 3 designates a brush portion that can be placed over the teeth attached to the tip of the handle portion 2. This brush part 3 is the handle part 2.
a first cover 5 fixed to the tip of the first cover 5;
A second cover 4 is attached to the cover 5 so that it can be opened and closed, and the second cover 4 is always attached so that the opening width of the opening between the first cover 5 and the second cover 4 is small. springs 6, 6, three holding holes 9, 10 formed in both side walls 7, 8 of the first cover 5, and a spiral ring rotatably attached to the holding holes 9, 10, respectively. shaped rotating brushes 12a, 12b, 12c, two holding holes 9, 10 each formed in both side walls 7a, 8a of the second cover 4, and rotatably attached to the holding holes 9, 10, respectively. Spiral rotating brush 12
d, 12e. 13 is the rotating brush 12a, 12b, 12c, 12d, 12
e is a transmission mechanism that rotationally drives the drive device (not shown) in the grip part 1, and this transmission mechanism 13 rotates the drive device ( (not shown), a pulley 15 fixed to the main shaft 14, and the spiral rotating brushes 12a, 12.
axes 22a, 22 of b, 12c, 12d, 12e
pulleys 16a, 16b, 16c, 16d, 16e fixed to b, 22c, 22d, 22e;
A rubber ring-shaped belt 17 stretched between the pulleys 15 and 16a, and the pulleys 16a and 16b.
a rubber ring-shaped belt 18 placed between the pulleys 16b and 16c, a rubber ring-shaped belt 20 placed between the pulleys 16a and 16d, and a rubber ring-shaped belt 18 placed between the pulleys 16b and 16c; 16e and a rubber ring-shaped belt 21 that is placed between the belt 16e and the belt 16e.

In the above configuration, when the brush portion 3 is placed over the teeth and the drive device (not shown) in the grip portion 1 is driven, the main shaft 14 rotates. For this reason, pulley 1
5, belt 17, pulley 16a, belt 18,
Pulley 16b, belt 19, pulley 16c and pulley 16a, belt 20, pulley 1
6d, the rotation of the belt 21, the pulley 16e, and the main shaft 14 is transmitted to create a spiral rotating brush 12a, 1.
2b, 12c, 12d, and 12e rotate, respectively. Therefore, the upper surfaces of the teeth and both sides of the gums can be brushed. Therefore, by holding the grip part 1 and moving the brush part 3 from the molars to the front teeth while covering them, the teeth can be easily cleaned.
You can perform pine surgery on your gums.

As is clear from the above explanation, in the present invention, several teeth, whether molars or front teeth, can be cleaned completely or just by the brush portion, using at least three rotating brushes that contact the upper part of the tooth and both sides of the tooth. By applying a rolling method to the gums where the tooth is located, you can simultaneously clean the teeth and perform pine surgery on the gums. Therefore, even an unskilled toothbrushing method for preventing dental caries and alveolar pyorrhea can be regularly and easily performed. Further, since the brush portion is opened and closed according to the width dimension of the teeth, the rotating brush can be brought into contact with the teeth in an optimal contact state. Therefore, there is a practical advantage in that it is possible to prevent complications caused by the brush coming into strong contact with the teeth as in the past.
