Abstract

(57) [Summary] [Purpose] In addition to cleaning teeth as a tooth brushing tool,
In particular, magnetic lines of force promote blood circulation in the gums. [Structure] Magnets (3) are installed at appropriate locations on a toothbrush body (1) in which bristle bundles (2) are implanted.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention not only cleans teeth as a toothbrushing tool, but also uses magnetic lines of force to The present invention relates to a toothbrush that has the effect of promoting blood circulation in the gums.

0002

[Conventional technology]

Traditionally, existing toothbrushes were designed to remove food residue and plaque. , by massaging the gums during use, it promotes blood flow to the gums and reduces plaque. ionizes and tartar, and has the effect of preventing and treating gingivitis, alveolar pyorrhea, etc. In order to increase A toothbrush has been proposed that has the following characteristics. (Jikko No. 62-30983 )

0003

[Problem that the idea aims to solve]

However, in the above-mentioned known toothbrush, the protrusions that serve as a massage effect are Insert a magnet into the innermost part of a hollow part of silicone rubber or plastic that has a closed tip. Since it is formed by placing it in position, the following new drawbacks have arisen.

0004 In other words, since the magnet is covered with silicone rubber, plastic, etc. The magnetic flux density of the stone does not directly affect the gums, etc., and As a result, effects such as promoting blood flow are not exerted. It became something. (Actually measured, the surface magnetic flux density is 3000 Gauss) Even if it is a stone, if it is separated by silicone rubber etc., the silicone It was confirmed that the surface magnetic flux density of rubber etc. was reduced to 1300 Gauss. )

[0005] Furthermore, in order to prevent the magnet from falling off, the diameter of the magnet is made slightly larger than the inner diameter of the hollow part. Not only does it have to be inserted until the tip of the protrusion bulges out from the base, but it also needs to be inserted into the remaining hollow part. The work efficiency is extremely low because a thin piece of resin must be inserted and filled, and the machine Because it is difficult to mass-produce using chemical technology, the cost has become extremely high.

[0006]

[Means to solve the problem]

The present invention is proposed to solve the above-mentioned new drawbacks, and is The toothbrush body is characterized by having magnetic bodies attached at appropriate locations. It is.

[0007]

[Effect]

Therefore, the present invention not only cleans the teeth with the hair bundle, but also cleans the teeth with the hair bundle. It uses magnetic lines of force to promote blood circulation in the gums.

[0008]

【Example】

The drawing shows one embodiment of the present invention, (1) is a toothbrush body; A plurality of hair bundles (2) made of nylon etc. are implanted in the main body (1). .

[0009] (3) is a soft material attached to the bristle bundle part (2) in the center row of the toothbrush body (1). It is a continuous magnet body, and the magnet body (3) has a through hole formed in the toothbrush body (1). (4) and is secured by the lid (5). The above magnet body (3) is magnetic A soft material made by kneading stone powder into rubber or plastic. These are called bonded magnets (plastic magnets, rubber magnets).

0010 Based on the above example, the magnet body (3) with a magnetic flux density of 1200 Gauss was moved between the magnets. Blood flow when a shaker is moved horizontally in a width of 1.5 cm from side to side once per second. The increase was measured with a laser Doppler blood flow meter and was found to be 0.44±0.07 volts. An increase in blood flow was observed.

[0011] Incidentally, each of the magnet bodies (3) may be separated and independent.

0012

[Effect of the idea]

As explained above, the present invention allows a magnet such as a bonded magnet to be brought into direct contact with the gums, etc. This allows the magnetic flux density of the magnet itself to act on the tooth. Not only does it promote blood circulation in meat, etc., but also as a known example, magnets can be attached to silicone rubber, etc. Mechanization is possible as there is no need for insertion, which is a very laborious process. This makes it possible to provide an inexpensive toothbrush.
