Description

Detailed Description of the Invention The present invention is a photoelectrochemical reaction formula that satisfies the four conditions of light, semiconductor, water, and teeth, converts light energy into electrical energy, and brings about tooth hygiene effects through polarization and reduction actions. Regarding oral hygiene devices.

When an M-type semiconductor having a photoelectric effect is irradiated with light to attract electrons, holes are provided due to the potential gradient of the space charge layer on the surface and polarization occurs. Teeth have opposite polarity due to the difference in electron density. Therefore, around semiconductors, lf! A dilation reaction occurs in which electrons are released from the liquid or water, while a reduction reaction occurs in which electrons are released from saliva or water at the tooth side. In other words, the tooth whose pH has decreased due to plaque and tartar adhering to the tooth is neutralized by a reduction reaction, and the demineralization of the tooth caused by the decrease in pH is effectively prevented. At the same time, the polarization action decomposes dental plaque, which is the cause of tooth decay, and also decomposes deposited pigments.
Therefore, as a whole, prevention of tooth decay, alveolar glue/wax, and beautification of teeth are linked in a t-childlike manner.

As a conventional oral hygiene device, a # is formed on the bristle part of a toothbrush, a semiconductor is fixed to this #, a light irradiation path toward the semiconductor is formed on the brush handle, and a transparent IF is formed from the irradiation path. The present inventors have already proposed a method in which a photogenic glass fiber is connected to a light source, but this method is expensive both for initial and running costs, and is inconvenient to handle.
The reason why this product required a light source of glass fiber and an irradiation path was because it was believed that unless the light beam was extremely strong, sufficient electricity would not be generated to produce the desired dental hygiene effect. .

However, recently, semiconductors with excellent photoelectric effects have been developed. Among them, titanium dioxide has a photoelectronic voltage on the order of 10 mV, for example, when the manufacturing conditions are positive 1, under natural light in the room when the lights are turned off on rainy days.

The present invention is based on this fact and the principle that no matter how low the voltage is, as long as electricity is generated, it means that a polarization effect has occurred, and the desired sanitary effect is achieved. It is a must-have for handling.

The photoelectrochemical reaction type oral hygiene device according to the present invention has a main body that integrates a part inserted into the oral cavity and a part exposed outside the oral cavity, and an M-type semiconductor having a photoelectric effect is attached to the exposed part, and the semiconductor A photoelectron current path is provided between the insertion portion and the insertion portion.

This is supported by the fact that it has been experimentally confirmed that a photon current is generated when natural light or ambient light such as a fluorescent lamp or an incandescent bulb is used as a light source. In other words, the present invention was developed in the field of oral hygiene devices such as C's Spear, under the circumstances where it has been considered absolutely necessary to have a dedicated artificial light with a considerably strong luminous intensity, and in light of the recent technological developments in photoelectric effect semiconductors. This is based on the fact that the desired sanitary effect (tft+) can be achieved as long as there is a polarization effect, that is, a photoelectron current.

According to the present invention, the conventionally required artificial light source, glass 7-eyeper, irradiation &i&, etc. can be omitted, resulting in a significant cost reduction and ease of handling.

Hereinafter, the enclosed cypress of the present invention will be explained based on the drawings.

Assume that the semiconductor is 141, and the tangent (T1) is 1200 to 1.
Titanium dioxide (TiOl) obtained by red-hot heating at 500"O for 2 to 10 minutes is preferable, but semiconducting C dye, which generates an appropriate photoelectron current even in natural light, can be sprinkled like a semiconductor modified with a shaft etc. Anything is acceptable as long as it includes any semiconductor that has been subjected to arbitrary treatment to increase its strength.
