Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Industry-1-] The present invention relates to a tooth brusher, and more particularly, to a tooth brusher that brushes teeth using ultrasonic waves.

[Prior Art] Conventionally, tooth brushers for brushing teeth include manual tooth brushes (normal toothbrushes, electric tooth brushers, jet tooth brushers, etc.).

The toothbrush mentioned above has been improved in its shape and brush tip so that it is easier to use, easier to brush, and can brush to the depths of the tooth and remove dirt and fine food particles. However, the drawback is that it is not very effective unless you spend a relatively long time polishing it, and it is troublesome.

Also, with a toothbrush, brushing too much may push the gums.
Undesirable effects such as flapping and peeling off the coating on the tooth surface often occur.

From this point of view, electric toothpastes or jet toothpastes that spray water were devised.

[Problems to be solved] Toothbrushes that are commonly used require the use of toothpaste or toothpaste, which has a relatively strong cleaning effect, and some of it is absorbed through the mouth, causing health problems. There are some disadvantages that are not so good. Well, it takes too much time to polish well.

Even if the electric type is used, toothpaste or toothpaste must be used, and since a large driving force is required, the driving device is large and difficult to handle. Additionally, even with smaller rechargeable electric toothbrushes, the handle is heavy due to the driving force.
Well, it doesn't necessarily reach all the way to the back, and there are limits to the range of movement of the brush part and the way it can be moved. Therefore, there is a drawback that fine control is not possible, and it is not possible to sufficiently remove small food particles, caked-on plaque, and tartar, etc., and achieve polishing to the extent that i<, -1·.

On the other hand, jet-spray toothpastes have the advantage of using only water or a thin cleaning solution without using toothpaste or powder, but the nozzle and the mechanism for spraying the water are separate. Therefore, it is necessary to connect them with a relatively thick pipe, which is difficult to handle as before, and the mechanical part that applies water pressure is large, which is unsatisfactory. However, depending on how the jet is adjusted, it may damage the gums and the polishing effect may not reach every corner.

[Purpose of the Invention] The present invention solves the problems of the prior art, and is capable of achieving a cleaning effect on areas using water or a thin cleaning solution without relatively damaging the gums or the teeth themselves. [1] To provide a toothpaste that can brush teeth in a short time and without any trouble.

[L-stage to solve the problem] The P-stage in the toothpaste of the present invention to achieve such an object is mounted on a plurality of tooth rows, and has grooves for covering these tooth rows, A plurality of holes for containing liquid formed on either the side surface, the bottom surface or the first surface of this groove, and a vibrator disposed inside the wall surface or the bottom surface of this groove and in contact with the holes. Dental braces with? It has r i < material.

In addition, the means in the tooth brushing device as the above-mentioned combined invention is installed in a plurality of 1↓1 rows, has a groove for covering these rows of teeth, and is formed on either the side surface, bottom surface, or bottom surface of this groove. A device comprising a plurality of liquid outflow holes, a liquid supply port, a liquid reservoir formed inside to communicate with each liquid outflow hole and the liquid supply port, and a vibrator disposed in the liquid reservoir. It is.

Furthermore, as another combined invention, a means in a toothpaste is
The teeth mounting member is attached to a plurality of tooth rows and has a groove and a liquid supply port for covering the tooth rows, and a liquid supply container is connected to the liquid supply L1 and supplies liquid to the tooth mounting member. hand,
A plurality of liquid outflow holes are formed on either the side surface, the bottom surface, or the bottom of the groove, and each liquid outflow hole communicates with the liquid supply inside the tooth mounting member or the liquid supply container. The vibrator is placed on either side.

[Operation] By forming a plurality of holes in the wall or bottom surface of the groove and the groove for covering a plurality of rows of teeth, and providing a vibrator inside or outside of the groove, the tooth insertion member can be inserted into the tooth. Just by inserting it into the row, you can use ultrasonic waves to brush your teeth in a short time.

There is no need to specifically explain the cleaning effect of ultrasonic waves, but if a small amount of water or cleaning liquid is present, the ultrasonic waves will propagate to the teeth, penetrate into the tooth surface and between the teeth, and clean the teeth. It has the effect of separating and removing dirt and small food particles that are stuck to the surface.

Moreover, since the tooth surface is not rubbed by hand or machine, the tooth surface and gums are not damaged, and the gums are not rubbed.
You can get a sufficient polishing effect in a short period of time without any damage.
