JP03021223U - Removing dental plaque by brushing is important to prevent oral diseases such as dental caries, periodontal diseases and so forth. However, it is known to medical experts, such as dentists, that there are lots of positions where dental plaque is difficult to remove. As a solution to this problem, a method has been conventionally fulfilled, which is to dye the dental plaque with a dying material after usual brushing and then to remove the dyed dental plaque by brushing. However, it is difficult to clearly remove the dental plaque since it is dark in the oral cavity and this makes it difficult for the user to directly view intomolar teeth or backside of teeth. Furthermore, oral diseases are generally found late, so that they often have a tendency to become serious. It is important to perform a self check in the house with a mirror with illumination in order to clearly remove the dental plaque and find the oral diseases earlier to prevent the oral diseases frombeing serious. However, such a mirror with illumination is not prevalent in general houses.
- The conventional one, for example, the dental mirror disclosed in Japanese Utility Model Registration No.
3066246 - further, the toothbrush with mirror disclosed in Japanese Patent Application Laid-Open No.
H 8-275826 - In addition, the head portion with bristles was integrated with the gripping portion and it was impossible to replace only the head portion with bristles by another one, and this gave rise to problems in terms of economies and environment.
- In the meanwhile, it is important for a guardian to fulfill tooth cleaning in order to prevent infant dental caries. In this connection, there is a tooth cleaning method called "brushing while being laid" or "finish brushing" among dental experts. This is a method of the guardian brushing infant teeth with a toothbrush for finish brushing while looking into the oral cavity, with the infant being laid upwards between both knees of the guardian. However, this method had a problem in that brushing is difficult to perform since it is dark in the oral cavity.
- Further, there is a case that requires an additional toothbrush used as an auxiliary toothbrush for cleaning between teeth in addition to the general toothbrush in order to prevent dental caries and periodontal diseases. For this case, the user should purchase two types of toothbrushes, each of which has its own brush handle for use, and this caused inconvenience. Furthermore, this gave rise to problems in terms of economies and environments.
- According to the present invention, there is provided a system toothbrush with illumination, comprising: a gripping portion that stores therein an LED light source and a battery, and has a switch for performing ON/OFF operations of the LED light source; and attachment portions detachably and compatibly connected to insertion holes that are formed in both ends of the gripping portion, wherein the attachment portions include at least a mirror portion and a toothbrush portion, and may further include an auxiliary toothbrush portion, wherein the LED light source is arranged so that, when the mirror portion is mounted at one end of the gripping portion, light emitted from the LED light source is directed to substantially the center of a mirror surface and, when the toothbrush portion is mounted at the one end of the gripping portion, light emitted from the LED light source is directed to the tip of bristles of a toothbrush head portion with bristles of the toothbrush portion.
- Embodiments of the present invention can provide a system toothbrush with illumination, which is composed of a gripping portion that stores an LED light source and a battery therein and attachment portions which are detachably connected to both ends of the gripping portion.
- With embodiments of the present invention, the attachment portions mounted at both ends of the gripping portion include at least a mirror portion and a toothbrush portion, and may further include an auxiliary toothbrush portion. Furthermore, the insertion holes formed in the both ends of the gripping portion may have the same shape. In this case, an insertion shaft formed in the attachment portion may be elastically fitted into the insertion hole, and this enables the mirror portion, the toothbrush portion, and the auxiliary toothbrush portion to be interchangeable to each other, thus allowing any combination to be made freely for use.
- Embodiments of the present invention can provide a system toothbrush with illumination, which may solve the above-mentioned problems described in relation to the Background Art with respect to health care in oral cavity at homes.
- In addition, in preferred embodiments, two thin, button-shaped lithium batteries, each of which supplies a voltage of 3V, are overlappingly arranged and stored in the horizontal orientation in the center of the gripping portion, so that the gripping portion may be made thin and light. By doing so, operability and storage capability may be improved in use. Furthermore, these batteries supply a voltage of 6V to the LED light source stored in the gripping portion, thus allowing light emission with high illuminance.
- The LED light source may be arranged in one of both ends of the gripping portion, and the combination of the LED light source and the batteries makes it possible to supply necessary light to the attachment portion mounted at the one end of the gripping portion where the LED light source is arranged. That is, the LED light source is arranged so that the light emitted from the LED light source is directed to the center of the mirror surface when the mirror portion is mounted as the attachment portion and the light is directed to the tip of bristles of the toothbrush head portion with bristles when the toothbrush head portion with bristles or the auxiliary toothbrush head portion with bristles is mounted as the attachment portion. In addition, such an arrangement of the LED light source in the end of the gripping portion makes it possible not to disturb brushing and enables a sufficient amount of light to be supplied in the oral cavity without interruption of light emitted from the LED light source when the toothbrush head portion with bristles or the auxiliary toothbrush head portion with bristles is mounted as the attachment portion at one end where the LED light source is arranged among both ends of the gripping portion.
- Further, as combinations of the gripping portion and the attachment portions, for example, when the mirror portion is mounted at the one end where the LED light source is arranged among both ends of the gripping portion, it may be used as a dental mirror with illumination, and when the toothbrush portion is mounted at one end where the LED light source is arranged among both ends of the gripping portion, it may be used as a toothbrush with illumination. Further, a user may observe the inside of his/her oral cavity with the dental mirror with illumination anytime he/she wants to without replacement of the equipment during usual brushing in a case where a toothbrush portion is additively mounted at the end of the gripping portion included in the constituent member as the dental mirror with illumination, and therefore, the user may use it without changing his/her usual brushing habit, thus it is expected the user conventionally performs a self check of his/her oral cavity without any difficulty.
- As such, it is not necessary for the user to separately purchase a dental mirror with illumination having a gripping portion, a general toothbrush having a gripping portion, an auxiliary toothbrush having a gripping portion, and the like, since embodiments of the toothbrush according to the present invention may be continuously used by additively buying only the necessary attachment portion and mounting the different attachment portion to both ends of the gripping portion. Accordingly, embodiments of the present invention may alleviate inconvenience of replacement of equipment during usual brushing and be advantageous in terms of user's economies and environments.
- Also, in further preferred embodiments, a storage insertion hole may be formed in the inside of each of both ends of the gripping portion, which is used for storing the attachment portions. The storage insertion hole is configured to insert and store the mirror portion or toothbrush portion detached from the end of the gripping portion. This enables the gripping portion to be stored in a toothbrush stand by detaching the attachment portion, which is mounted at one end of both ends of the gripping portion, and storing it in the storage insertion hole located at the opposite end.
- As described above, embodiments of the system toothbrush with illumination according to the present invention, may allow a user to easily observe the inside of the oral cavity with the dental mirror with illumination upon tooth brushing in the house, thus it is expected to enable the user to conventionally perform a self check of the oral cavity in daily life. This improves efficiency of tooth brushing and therefore contributes to prevention and early detection of oral diseases. In addition, embodiments of the system toothbrush with illumination according to the present invention may replace the attachment portion with another one, and this may lessen user's economical burdens and improve environmental problems.
- Furthermore, embodiments of the system toothbrush with illumination according to the present invention may save costs in development and production in terms of manufacturing aspects, compared with separately manufacturing each of the dental mirror with illumination, the toothbrush with mirror, the toothbrush with illumination, and the like.
