JPH11113638A - Slim and small magnetic field toothbrush - Google Patents

Abstract

PROBLEM TO BE SOLVED: To promote gingival blood flow by providing a magnetic field in a toothbrush and making the toothbrush's shape slim and small. SOLUTION: The toothbrush has a bristled portion 1, the surrounding portion having bristles 3 except the other portion in which a magnet 2 for example is embedded, and vertical magnetic lines of force. Since the thickness I2 of the magnet is contained in the thickness I1 of ordinary bristles, it has magnetic fields and remains slim. When such toothbrush is used, according to Fleming's right-hand rule, blood flow is facilitated in the directions of magnetic fields of the toothbrush which are perpendicular to each other and in the direction vertical to the direction of brushing motion. Brushing and Fleming's high-hand rule helps improve blood flow in the oral cavity from the inside of the gum, and prevent paradentitis or dentoalveolitis and make the bristled portion and bristles themselves a source of magnetic forces without changing the entire shape, and like an ordinary toothbrush, it can be downsized and can be moved freely in the oral cavity.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a toothbrush for promoting gingival blood circulation.

[0002]

2. Description of the Related Art A conventional toothbrush promotes blood circulation to prevent periodontal disease and prevents periodontal disease by simply brushing teeth. However, the conventional toothbrush merely rubs the gingival epithelium and has no effect of promoting blood circulation of the gums and roots.

[0003]

A toothbrush for providing a magnetic field to a toothbrush and having a thin and small outer shape to improve blood circulation in the gingiva.

[0004]

SUMMARY OF THE INVENTION A magnetic field is provided on a toothbrush portion in a small size as a whole.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A magnet is inserted into a portion other than a flocked portion, or a flocked portion or a flocked portion is made of a magnetic material.

[0006]

BRIEF DESCRIPTION OF mounting the magnet section 2 of the thickness l ₂ 'on the back of the thickness l ₁ flocked portion 1 of the toothbrush as shown in FIG. 1, the total thickness L in l 1 ₊ l ₂ is increased, the mouth Can not move enough to brush the teeth. Therefore, the present invention has a flocked portion 1 in which a flocked portion 3 is implanted around a portion where the magnet 2 is buried as shown in FIG. 2, for example, as shown in FIG. 2, and FIG. It is. This is the magnet portion thickness l ₂ fall within the normal flocking thickness l _1, the thickness of and toothbrush having a magnetic field L
Does not thicken.

FIG. 4 shows the magnet 2 of FIG. 3 buried in the width direction so as to have a magnetic field in the width direction of the toothbrush, and flocked before and after the magnet. Get out.

FIG. 5 shows a structure in which a thin sheet-like magnet 6 is provided on the back surface of the back portion 5 of the nuclear hair portion 1, and its cross section is as shown in FIG. The magnetic sheet may be punched out of a magnetic tape or floppy coated on a polyester sheet 6 with a pressure-sensitive adhesive 7 and then attached to a ready-made toothbrush. It may be provided when forming.

FIG. 7 shows an example in which a magnetic powder 9 is mixed into the flocking 3 itself to make the flocking itself a magnetic material. FIG.
Is an embodiment in which magnetic powder 9 is put in a hollow fiber 10 having a pipe shape. FIG. 9 shows that the magnetic powder 9 is applied to or mixed with the tip 11 of the flocking 3 that comes into contact with the gingiva and is magnetized. FIG. 10 is an embodiment of the present invention in which the magnetic powder 9 is mixed into the material of the flocking portion 1.

All other various modifications and combinations of the above embodiment are included in the present invention, and the magnetic sheet alone shown in FIG. 5 is also included in the present invention.

FIG. 11 shows the principle of operation of the present invention. When the toothbrush of the present invention is used, if the direction B of the magnetic field of the toothbrush and the direction of the tooth brushing motion are V at right angles to each other according to Fleming's right hand rule, It shows that blood circulation is promoted in the direction of I.

[0012]

The present invention improves the blood circulation in the oral cavity from inside the gingiva according to Fleming's law while brushing the teeth with a toothbrush, prevents alveolar purulence and gingivitis, and does not change the external shape of the conventional toothbrush. Since the hair transplants and hair transplants can be used as a magnetic force source, they have remarkable effects such as being miniaturized and being freely moved in the oral cavity like a normal toothbrush, and greatly contributing to the health of the people in health It is an invention.
