Abstract

PURPOSE:To enhance the cleaning effect of the teeth and to intensify the massage effect of the gingiva by embedding permanent magnets into the longitudinal direction of a brush part and applying magnetic fields within the oral cavity. CONSTITUTION:The brush part 18 is embedded with the permanent magnets 20a, 20b in the longitudinal direction of the brush part 18. The permanent magnets 20a, 20b are connected by a yoke 22. Poles facing each other are arranged in the permanent magnets 20a, 20b in such a manner that these poles are respectively the poles varying from each other, such as an N pole and S pole. Then, the permanent magnets 20a, 20b attract each other. The cleaning effect of the teeth is accelerated and the massage effect of the gingiva by brushing is intensified if the magnetic fields are applied within the oral cavity and the teeth and the gingiva are subjected to the brushing motion by this magnetic tooth brush. The diseases of the teeth are prevented by using this magnetic tooth brush and the maintenance and promotion of the health of the teeth are assisted by these effects.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic toothbrush which enhances the hygienic effect of the oral cavity and teeth by applying a magnetic field to the oral cavity, particularly to the teeth and gums.

[0002]

2. Description of the Related Art As a conventional toothbrush, there is one in which animal hair or hair made of synthetic resin such as nylon is implanted. If you brush your teeth with such a toothbrush, the bristles and projections on your head will remove dirt from your teeth and stimulate your gums.

[0003]

However, when brushing teeth with a conventional toothbrush, brushing the teeth and gums is not sufficient for cleaning the teeth and massaging the gums.

Therefore, the main object of the present invention is to enhance the cleaning effect of teeth and the massage effect of gums by brushing the oral cavity, especially teeth and gums, prevent tooth diseases and maintain dental health. And to provide a magnetic toothbrush, which can be used for promotion.

[0005]

According to the present invention, there is provided a handle, a brush portion formed at an end portion of the handle, and a brush portion is brushed on a side portion thereof, and the brush portion is embedded in a longitudinal direction of the brush portion. A magnetic toothbrush including one or more permanent magnets.

[0006]

In the brush unit, one or more permanent magnets are embedded in the brush unit in the longitudinal direction. The permanent magnet provides a magnetic field in the oral cavity, especially in the teeth and gums.

[0007]

According to the present invention, a tooth cleaning effect is promoted by applying a magnetic field in the oral cavity. Further, the massage effect on the gum due to brushing is enhanced. Furthermore, according to the present invention, it is possible to enhance and strengthen the blood circulation of the gums, remove plaque, strengthen the teeth, prevent halitosis, prevent dental caries, prevent pyorrhea, and disinfect or sterilize the oral cavity. It is effective and can prevent dental diseases and help maintain and improve dental health.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

[0009]

1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an illustrative view showing its internal structure.

The magnetic toothbrush 10 includes a rod-shaped handle 12. The handle 12 is made of synthetic resin such as acrylonitrile-styrene resin. A handle portion 14 for holding by hand extends from one end of the handle 12. Also, handle 12
At the other end of the brush, a brush portion 1 having a brush 16 planted on its side
8 is formed.

As shown in FIG. 2, permanent magnets 20a and 20b are embedded in the brush portion 18 in the longitudinal direction of the brush portion 18. Ferrite magnets, rare earth magnets, and the like are used as the permanent magnets 20a and 20b. The permanent magnets 20a and 20b are connected by a yoke 22.
In the permanent magnets 20a and 20b, the poles facing each other are arranged to be different poles such as N pole and S pole, respectively. Therefore, the permanent magnet 20
a and 20b attract each other.

FIG. 3 is an illustrative view showing a usage example of the magnetic toothbrush 10. In this manner, the magnetic toothbrush 10 brushes the teeth 24 and gums 26. At this time, the brush 16 side of the brush portion 18 is dipped in an electrolyte solution such as saliva, water, or two-space.

According to the present invention, when a magnetic field is applied to the oral cavity and the teeth and gums are brushed by this magnetic toothbrush, the tooth cleaning effect is promoted and the gum massage effect by brushing is enhanced. In addition, blood circulation and strengthening of the gums, removal of plaque, strengthening of dentin,
It is effective in preventing bad breath, preventing tooth decay, preventing alveolar pyorrhea, and disinfecting or sterilizing the oral cavity. Due to these effects, by using this magnetic toothbrush, it is possible to prevent tooth diseases and maintain and improve the health of teeth.

FIG. 4 is an illustrative view showing another embodiment of the present invention. In this embodiment, in particular one permanent magnet 20
The brush portion 18 is embedded in the brush portion 18 in the longitudinal direction.

FIG. 5 is an illustrative view showing still another embodiment of the present invention. In this embodiment, in particular four permanent magnets 2
0a, 20b, 20c, 20d are embedded in the brush portion 18 so that the poles facing each other in the longitudinal direction of the brush portion 18 are different poles such as N pole and S pole, respectively. In this case, the adjacent permanent magnets 20
The a, 20b, 20c and 20d attract each other.

FIG. 6 is an illustrative view showing another embodiment of the present invention. In this embodiment, in particular, three permanent magnets 20a,
20b and 20c are embedded in the brush portion 18 so that the poles facing each other in the longitudinal direction of the brush portion 18 are the same poles such as N pole and N pole, respectively. In this case, the adjacent permanent magnets 20a, 20b, 20c
Repel each other.

Also in each of these embodiments, a magnetic field is applied to the oral cavity, especially to the teeth and gums, and the cleaning effect on the teeth and the massage effect on the gums can be enhanced.

This magnetic toothbrush may be used by appropriately changing the combination of permanent magnets so as to obtain an appropriate magnetic flux density.
