Description

  The present invention relates to an ultraviolet ray treatment device that uses the energy of ultraviolet rays contained in sunlight to sterilize and deodorize between the soles of the feet and the toes.

  Conventionally, the area between the soles of the feet and the toes below the ankle is less likely to be exposed to sunlight, so it is usually easy to get steamed, and one in 10 people in Japan that causes ringworm bacteria to grow on the skin and cause athlete's foot Yes. As a treatment, it is possible to sterilize with sunlight from the ankles under sunlight, but the direct sunlight does not hit directly between the soles or toes of the feet. The effect that appears is not obtained.

  In addition, devices for irradiating with ultraviolet lamps have been commercialized. However, in this configuration, since the entire sole of the foot is not exposed to light, the effect of treatment is uneven. Moreover, since the wavelength of the ultraviolet rays is harmful to the skin, it could not be irradiated for a long time.

  Japanese Laid-Open Patent Publication No. 2001-120591 has been proposed as a publicly known gazette, but even in this configuration, when the toes are forcibly spread, the angle of the gap between each finger is slightly shifted in a fan shape. Even if sunlight strikes between the toes, sunlight does not strike between the other toes, so treatment (treatment) between each finger cannot be performed at the same time. In addition, the sun is constantly moving, and in order to irradiate the affected area for a predetermined time, the fingertip must always be directed toward the sun.

JP 2001-120591 A

  The present invention has been made in view of the above-mentioned problems, and enables direct irradiation of light irradiated from the sun from any direction so that the light can be efficiently irradiated between the soles of the feet and the toes, It is intended to sterilize and deodorize the skin irradiated with ultraviolet rays contained in the sunlight, and to obtain a strong sterilization and deodorization effect even with weak light by utilizing the photocatalytic action of titanium oxide. .

  In order to solve the above-mentioned problems, the present invention utilizes the light-guiding property of the translucent resin, and the light incident on the light-guiding resin body is repeatedly reflected and diffused on the inner surface of the resin body. Because the light that reflects and diffuses can reach any shape of the resin body, the light guide resin body holds between the toes, the insole on the sole of the foot, and the footwear to be worn barefoot Thus, when the resin body is worn, sunlight incident on the exposed light receiving surface is reflected and diffused in the resin body, and part or all of the diffused light is between the soles of the feet and the toes. The skin surface irradiated with ultraviolet rays of the light is sterilized and deodorized.

  In addition, a portion that contacts the sole of the foot and the toes is formed in the light guiding resin body, and a titanium oxide film is provided on the contacting surface to absorb the ultraviolet rays irradiated to the portion and oxidize. The photocatalytic reaction is caused by titanium, and the skin surface that comes into contact is sterilized and deodorized by the strong redox reaction.

  The ultraviolet ray treatment device of the present invention allows light to be incident on the exposed light receiving surface by sunlight from any direction, and allows light to be incident from a wide light receiving surface, and diffuses the light in the light guide resin body. Because the skin surface of the foot can be irradiated, efficient and stable treatment can be performed. In addition, no matter what shape the ultraviolet treatment device of the present invention is formed, once incident light is reflected and diffused on its inner surface, and the light reaches the details, treatment is performed by irradiating constant light on any skin surface. There is no unevenness or waste of light. In addition, since the present invention has a very inexpensive configuration and uses near-ultraviolet rays of natural sunlight, it is harmless to the human body and can be treated while walking outdoors, so a very healthy sterilization and deodorization treatment is possible. it can. Further, the product of the present invention does not lose its treatment effect even if it is washed many times, and can be used for a long time and is economical.

  Sunlight contains ultraviolet rays, and is classified into UV-A (320 to 400 nm), UV-B (280 to 320 nm), and UV-C (280 nm or less) depending on the wavelength. Here, UV-C is absorbed by the ozone layer and the atmosphere, and UV-B is absorbed when passing through the window glass and resin. UV-A is called near-ultraviolet rays and is completely harmless to human skin, but has the property of penetrating through window glass and resin to reach the deep part of the skin, and has a sterilizing and deodorizing action.

When light having a wavelength of 300 to 380 nm, which is near ultraviolet rays, is irradiated onto a titanium oxide film that is a photocatalyst, the ultraviolet rays are absorbed and electrons are excited by the photoelectric effect to generate electrons and holes. These electrons and holes combine with oxygen and moisture in the air on the surface of the photocatalyst to cause an oxidation-reduction reaction, thereby generating active oxygen species O ₂ ⁻ , O ⁻ , and OH. The generated active oxygen has an extremely strong oxidizing power, sterilizes bacteria and viruses by oxidative decomposition, and has a deodorizing and deodorizing action.

  The present invention applies the properties inherent to the near-ultraviolet rays contained in the above-described sunlight, and further applies the photocatalytic action of titanium oxide by ultraviolet rays. Embodiments of the present invention will be described with reference to the drawings.

In the structure of the holder 1A, as shown in FIG. 1B, when sunlight hits the light receiving surface 1a exposed on the upper surface, the sunlight enters the light receiving surface 1a. Here, when light enters the resin body from the air, the incident light is refracted and travels downward. For this reason, incident light can be guided downward using the refraction action of this light, and the light can be refracted and guided downward in the holder 1A even when the sun is inclined to the horizon. Can do. The incident light is repeatedly reflected and diffused in the holder 1A, and the light that has been made uniform to some extent is irradiated from the inside of the holder 1A to the outside.
