Description

  The present invention relates to an optical toothbrush that mainly cares about the oral cavity using LED illumination.

  Dental caries and periodontal disease, two major diseases in the dental field, are the main causes of tooth loss. For this reason, various optical toothbrushes for preventing these diseases have been proposed, and a number of optical toothbrushes using light and electric power have been proposed.

  As an action of light and oral tissues, many effects such as wound healing, sterilization effect, pain reduction have been reported so far (Japan Laser Dentistry Association etc.), and as an optical toothbrush using such light technology, For example, those described in US Pat. No. 3,667,454, Japanese Patent Application Laid-Open No. 2002-223854, Japanese Patent Application Laid-Open No. 2005-348799, and Japanese Patent Application Laid-Open No. 2009-22697 have been proposed.

  U.S. Pat. No. 3,667,454 is an electric light toothbrush in which an ultraviolet lamp having a sterilizing effect is installed in the rear end of the toothbrush at the tip of the toothbrush, and a vibrator is provided in the toothbrush body. Electric brushing can be performed while sterilizing teeth and periodontal by irradiation.

  JP-A-2002-223854 provides an oral care product in which irradiation light is not blocked by deformation of a toothbrush's flocked portion during brushing by providing a light emitting portion on the side, tip, back, or handle of the flocked portion. I can do it.

  Japanese Patent Laid-Open No. 2005-348799 stores a light-transmitting member for guiding light from a light source to a flocked portion inside the main body, and roughens the flocked portion-side front end surface of the light-transmissive member. It is said that it is possible to provide a light toothbrush for preventing caries, alveolar pus leakage and tooth odor that can be brushed while irradiating light from the part.

  Japanese Patent Application Laid-Open No. 2009-22697 discloses a light source provided at the tip of a toothbrush handle container without a waterproof seal process in which a light transmitting hole is provided in the center of a flock of a replacement toothbrush and the inside thereof is a hollow body and a vibration source is mounted on the hollow body. By adopting a structure in which the light-transmitting portion covering the detachable can be detachably inserted, it is possible to provide an inexpensive light toothbrush excellent in illumination efficiency that facilitates a waterproof seal structure of the light source and can also perform a physical purification action.

  On the other hand, electric toothbrushes are easy to brush and can effectively clean teeth, so many products are provided. However, since they are not portable, they are mostly used in homes or workplaces. It was inconvenient. In recent years, an electric toothbrush with improved portability: Pocket Doltz (Panasonic) has been commercialized.

US Pat. No. 3,667,454 JP 2002-223854 A JP 2005-348799 A JP 2009-22697 A

  However, in the former US Pat. No. 3,667,454 and JP-A-2009-22697, the light source is deteriorated by vibration and the reliability is maintained due to the brushing by the vibrator with the light source arranged at the flocked portion of the toothbrush tip. Is difficult. Furthermore, since it is light irradiation toward the brushing target part from the flocked part, it is difficult to obtain good irradiation efficiency because light is scattered and absorbed by toothpaste and the like.

  The one described in Japanese Patent Application Laid-Open No. 2005-348799 is also light irradiation directed from the flocked part to the target site for brushing, and thus is scattered and absorbed by toothpaste and the like. It is difficult to obtain the expected effect on the living body with the light output that is acceptable for use in

  Moreover, the thing of Unexamined-Japanese-Patent No. 2002-223854 does not block irradiation light by the deformation | transformation of the hair-planting part of a toothbrush at the time of brushing by providing a light emission part in the side surface, front-end | tip, back surface, or handle | pattern of a hair-planting part. Although it is said that oral care products can be provided, it is difficult to obtain good irradiation efficiency because the irradiation light is scattered and absorbed by toothpaste attached to the irradiation site, as with the former one It is difficult to obtain the expected effect on the living body with light output that is possible in general homes, and in addition, the irradiation structure does not match the brushed part and the irradiated part, so a mechanism to prevent erroneous irradiation to the human body is essential Therefore, the configuration is complicated.

  As described above, the toothbrush that uses light so far irradiates light from the tip part direction, therefore, considering the waterproof mechanism for transmitting light to the replacement toothbrush that is a consumable item, A special light source is installed on the toothbrush body (holding part) and light is guided from the fiber tip to the tip using an optical fiber from here, or a specially shaped LED is placed on the tip for irradiation. In addition, since the brushing is performed while irradiating, the irradiation light is scattered and absorbed by toothpaste, and it is difficult to obtain the expected effect on the living body.

  On the other hand, for electric toothbrushes, products with improved portability have been proposed. However, despite the many useful uses of light for oral care, as described above, incorporating an electric function into an optical toothbrush that emits light from the tip end area so far is not possible. Since it is difficult and high irradiation efficiency cannot be expected, an electric toothbrush product with an irradiation function excellent in portability has not been realized.

  The present invention has been conceived based on such facts, and can be effectively used for oral care of various lights even with a light output that is acceptable in a general household, and is portable so that these oral care can be performed anytime and anywhere. An object of the present invention is to provide a toothbrush with an illumination function that is superior to the above.

When it is determined that it is sufficient, the brushing is finished, the cap 10 is attached to the toothbrush main body 30, and returned into the bag, it can be easily carried to the next brushing place.

  At this time, it is also possible to perform oral care of light suitable for the purpose of use of the main body bottom cover 32 selected and worn by the user. For example, in the illumination with the toothbrush with an illumination function according to the first invention in which the main body bottom cover 32 mounted with a green or blue LED is selected from the lineup of the main body bottom cover 32, the carious portion Since the contrast between the calculus and the calculus in the periodontium and the healthy part can be increased, it is possible to check not only the state of brushing but also the health of the oral cavity. In addition, the toothbrush with illumination function equipped with the main body bottom lid 32 equipped with a red LED can be expected to improve the periodontal tissue due to the red blood circulation promoting effect. Furthermore, in the configuration of the electric toothbrush with illumination function according to the present invention, the main body having LEDs of different colors is mounted by mounting the main body bottom cover 32 having the light source switch 322 having the full color LED and the hue control function on the light source element 3231. It is also possible to make it usable for oral care of various types of light without replacing the bottom lid 32.

  On the other hand, the toothbrush with illumination function according to the third invention can be configured so that a small bottle 317 can be stored and carried in a space obtained by mounting a plurality of LEDs, and a synergistic effect of oral care with light is expected. The small bottle 317 containing the paste to be stored can be stored and carried. For example, a small bottle 317 containing a paste containing titanium dioxide, silicon carbide, etc. is housed, and a light brush using a toothbrush with a lighting function equipped with a main body bottom cover 32 on which three high-intensity blue LEDs are mounted is used. In oral care, the sterilization effect by the photocatalytic effect is expected. In addition to the materials described above, for example, toothpaste, whitening paste, and the like can be carried and the effect of using light illumination can be greatly improved. Here, as the main body bottom cover 30 to be installed on the toothbrush with illumination function according to the third invention, all LEDs of the same color are appropriately selected and mounted for those who need bright irradiation and want to use for one type of oral care.
