Description

本発明は、電動式歯間ブラシ、殊に歯ブラシとしても使用可能な歯ブラシ兼用電動歯間ブラシに関するものである。   The present invention relates to an electric interdental brush, and more particularly to an electric interdental brush that can also be used as a toothbrush.

従来から、歯間に堆積した歯垢や食物残滓は、虫歯と歯槽膿漏の原因である細菌の温床となり、これを除去するために歯間ブラシが使用されており、効率よく且つ確実に歯垢や食物残滓を除去する目的で電動歯間ブラシが例えば実開平５−３４９２４号公報、実開平７−２５８２９号公報などに提示されている。
前記公報に提示されている電動歯間ブラシは、振動発生手段と、前記振動発生手段の駆動電源と、前記振動発生手段および駆動電源のスイッチを含む制御部を内蔵した筒状のケース本体の先端に前記振動発生手段により出力される振動により往復動する歯間ブラシが配置されたものであり、駆動電源として電池を使用することによりコードレスで携行にも便利なものとなっている。また、歯間ブラシがケース本体の軸心に対して例えば４５度程度に傾斜している場合が歯間の清掃に都合がよいことも知られている。
ところが、前記公報に提示されている電動歯間ブラシは歯間の清掃作業には適しているが、歯の１つ１つを対象にすることから通常の歯磨き用として用いるには作業が煩雑であり通常の電動歯ブラシのように使用することができない。
従って、電動歯間ブラシとは別に電動歯ブラシを使用する必要があり、双方を購入することになり、経済的負担が増えることはいうまでもなく、洗面所などにおける設置場所の確保や携行にも不便であるという問題があった。Conventionally, plaque and food residue accumulated between teeth has become a hotbed of bacteria that cause caries and alveolar pus leakage, and an interdental brush has been used to remove this, effectively and reliably. For the purpose of removing dirt and food residue, electric interdental brushes are presented in, for example, Japanese Utility Model Laid-Open No. 5-34924 and Japanese Utility Model Laid-Open No. 7-25829.
The electric interdental brush presented in the above publication includes a vibration generating means, a driving power source for the vibration generating means, and a tip of a cylindrical case body that includes a control unit including the vibration generating means and a switch for the driving power supply. Further, an interdental brush that reciprocates due to the vibration output from the vibration generating means is disposed. By using a battery as a driving power source, it is cordless and convenient to carry. It is also known that when the interdental brush is inclined at, for example, about 45 degrees with respect to the axis of the case body, it is convenient for interdental cleaning.
However, although the electric interdental brush presented in the above publication is suitable for interdental cleaning work, it is complicated to use for normal tooth brushing because it is intended for each tooth. It cannot be used like a normal electric toothbrush.
Therefore, it is necessary to use an electric toothbrush separately from the electric interdental brush, and it will be necessary to purchase both, which will increase the economic burden, as well as securing and carrying the installation place in the washroom etc. There was a problem of inconvenience.

実開平５−３４９２４号公Utility Kaihei 5-34924 実開平７−２５８２９号公報Japanese Utility Model Publication No. 7-25829

本発明は、上紀のような問題を解決しようとするものであり、特に、１つのケース本体を用いて歯間の清掃および歯磨きの両方が可能な歯ブラシ兼用電動歯間ブラシを提供することを課題とする。   The present invention is intended to solve the problems such as the early age, and in particular, to provide an electric interdental brush combined with a toothbrush capable of performing both interdental cleaning and brushing using a single case body. Let it be an issue.

前記課題を解決するためになされた本発明は、振動発生手段と、前記振動発生手段の駆動電源と、前記振動発生手段および駆動電源のスイッチを含む制御部を内蔵したケース本体の先端に前記振動発生手段により出力される振動により往復動する歯間ブラシが前記ケース本体の軸線に沿って配置されているとともに、先端に歯ブラシを付設した底面を開放した歯ブラシ部材が前記歯間ブラシを覆って取り外し可能に前記ケース本体の先端に嵌装可能であり、前記歯ブラシ部材を嵌装させたときに前記振動発生手段により出力される振動により前記歯ブラシが往復動することを特徴とする。
本発明によれば、ケース本体の先端に配置した歯間ブラシを、ケース本体に内蔵した振動発生手段により出力される振動により往復動させて歯間清掃を行う。また、先端に歯ブラシを付設した底面を開放した歯ブラシ部材を前記歯間ブラシを覆ってケース本体の先端に嵌装して、歯ブラシ部材を往復動させて歯磨きを行う。
特に、通常は歯間ブラシに歯ブラシ部材を被せた状態とすることにより別部品として保管或いは携行する必要がなく、場所を取らずに保管し、容易に携行することもできる。
また、本発明において、前記歯間ブラシが基端において所定の角度に傾倒可能に前記ケース本体に支持させることにより、歯間ブラシを使用するときに、従来の電動歯間ブラシのように歯間ブラシを所定の角度に傾斜させた状態で使用することが可能であり、きわめて効率のよい歯間清掃を行うことができる。
更に、本発明において、前記歯間ブラシのブラシ部が交換可能とすることにより、細くて消耗し易い歯間ブラシを新たなものに交換して長期の使用を可能にすることができる。
更にまた、前記ケース本体の先端に歯ブラシ部材を嵌装させた状態で取り外し可能に筒状キャップを嵌装することにより、歯間ブラシを歯ブラシ部材を被せた状態で被蓋することができ、保管や携行にも適しており、殊に、前記ケース本体の先端に被せた筒状キャップを外して前記ケース本体の基部に取り付けることにより外した筒状キャップの置き場所が不要であるだけでなく、ケース本体の長さを伸ばして掴み易くすることができるのでケース本体の長さを短くして全体を小型化することもできる。The present invention, which has been made to solve the above-mentioned problems, includes a vibration generating means, a driving power source for the vibration generating means, and a vibration control unit including a control unit including a switch for the vibration generating means and the driving power source. An interdental brush that reciprocates due to vibration output from the generating means is disposed along the axis of the case body, and a toothbrush member that has a toothbrush attached to the tip and that has an open bottom covers and covers the interdental brush. The toothbrush can be fitted to the tip of the case body as possible, and the toothbrush reciprocates due to vibration output by the vibration generating means when the toothbrush member is fitted.
According to the present invention, the interdental brush disposed at the tip of the case main body is reciprocated by the vibration output from the vibration generating means built in the case main body to perform interdental cleaning. Further, a toothbrush member having a toothbrush attached to the tip and having a bottom opened is fitted on the tip of the case body so as to cover the interdental brush, and the toothbrush member is reciprocated to brush the teeth.
In particular, it is usually not necessary to store or carry as a separate part by putting the toothbrush member on the interdental brush, and it can be stored without taking up space and can be easily carried.
Further, in the present invention, when the interdental brush is used, the interdental brush is supported by the case main body so that the interdental brush can tilt at a predetermined angle at the base end, so that the interdental brush is used like a conventional electric interdental brush. The brush can be used in a state where the brush is inclined at a predetermined angle, and extremely efficient interdental cleaning can be performed.
Furthermore, in the present invention, by making the brush part of the interdental brush replaceable, the interdental brush that is thin and easy to wear can be replaced with a new one to enable long-term use.
Furthermore, the interdental brush can be covered with the toothbrush member covered by detachably fitting a cylindrical cap with the toothbrush member fitted to the tip of the case body. It is also suitable for carrying, and in particular, not only is the installation place of the cylindrical cap removed by removing the cylindrical cap placed on the tip of the case main body and attaching it to the base of the case main body, Since the length of the case main body can be extended and easily grasped, the length of the case main body can be shortened to reduce the whole size.

本発明によれば、１つのケース本体を用いて歯間の清掃および歯磨きの両方が可能な歯ブラシ兼用電動歯間ブラシを提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the toothbrush combined electric interdental brush which can perform both cleaning between teeth and brushing using one case main body can be provided.

次に、本発明を実施するための最良の形態を図面に基づいて説明する。
図面は本発明に係る歯ブラシ兼用電動歯間ブラシの好ましい実施の形態を示すものであり、本実施の形態は、図１に示すように、主として先端に歯間ブラシ部材２を配置した有底筒状のケース本体１と、前記歯間ブラシ２部材を覆って取り外し可能にケース本体１の先端に嵌装される歯ブラシ部材３と、前記ケース本体１の先端側から被せられる筒状キャップ４とから構成される。
特に、本実施の形態では、歯間ブラシ部材２はケース本体１の先端に配置された支持部材１６に支持された基部２２とその先端に配置されたブラシ部２１とからなり、図２および図３に示すように、歯間ブラシ部材２を基部２２を中心としてケース本体１の軸心に沿う状態から例えば４５度の所定角度に傾動可能に配置されており、図４および図５に示すように、歯間ブラシ部材２をケース本体１の軸心に沿う状態として歯ブラシ部材３を被せる。
また、ケース本体には係止突起１５が歯ブラシ部材３には前記係止突起１５を嵌める係止窓３２が形成されており、筒状キャップ４の頂面には水抜き孔４１が形成されている。
ケース本体１内には、例えば偏芯錘を軸着したモータのような振動発生手段１１と、前記振動発生手段１１のバッテリからなる駆動電源１２と、前記振動発生手段１１および駆動電源１２のスイッチ１４を含む制御部１５を内蔵しており、外面に露出したスイッチ１４を操作するための押しボタン１７をオン操作することにより振動発生手段１１により出力される振動により歯間ブラシ部材２のブラシ部２１が往復動する構成である。
従って、図２および図３に示すように、歯ブラシ部材３を取り外した状態で歯間ブラシ部材２を往復動させて歯間に詰まった食べ残しや歯垢を取り除く、このとき、基部２２を回転させて歯間ブラシ部材２を従来の歯間ブラシのように傾斜させると使用し易い。また、支持部材１６に歯間ブラシ部材２の基部２２が所定の傾斜角度で停止するようにストッパーを設けておくとよく、歯間ブラシ部材２が所定の角度で保持されるので使用中に傾斜が変化する心配もない。
更に、図９及び図１０の歯間ブラシ部材２の拡大図が示すように、歯間ブラシ部材２は、ケース本体から交換可能に取り付けられており、ケース本体の凸部１８と歯間ブラシ基部２２の凹部２３とが嵌合することにより嵌装される。
また、歯間ブラシ部材２は、ケース本体と回転可能に嵌合されており、例えば図１１から図１３に示すように、数段階に角度が調節可能に配置されるとともに、各角度段階において、歯間ブラシ基部２２に設けられた凹部４１ａ，４１ｂ，４１ｃがケース本体に設けられた凸部４２とそれぞれ嵌合することにより、ストッパーの働きをして、歯間ブラシ部材２を所定の角度（例えば、１８０度の歯ブラシ部材３を被せる状態、４５度の歯間ブラシ部材２として使用する状態、９０度の歯間ブラシ部材２として使用する状態）で保持可能とするように構成されている。
そして、食事の後や睡眠前に歯磨きをする場合には、歯間ブラシ部材２の部分を図１、図２（ａ）に示すように、歯間ブラシ部材２をケース本体１の軸線に合わせた状態として図４および図５に示すようにケース本体１の先部に歯ブラシ部材３を被せて前記振動発生手段１１により出力される振動により歯ブラシ部材３のブラシ部３１１が往復動するので従来の電動歯ブラシと同様に使用する。
このとき、本実施の形態では、ケース本体に形成した係止突起１５が歯ブラシ部材３に形成した係止窓３２に係止することにより歯ブラシ部材３が確実にケースに装着され、また、係止窓３２から係止突起１５を押し出すことにより簡単に係合を解除することができる。
このとき、本実施の形態では、ケース本体に形成した係止突起１５が歯ブラシ部材３に形成した係止窓３２に係止することにより歯ブラシ部材３が確実にケース本体３に支持されるので確実に振動が伝わる。殊に、本実施の形態では歯ブラシ部材３に空気抜き３３が形成されているので歯ブラシ部材３の内部の空気が振動により干渉したりする心配もない。
また、本実施の形態では、図３（ｂ），図９に示すように、歯間ブラシ２のブラシ部２１が保持部２１１に固着されて交換可能であり、歯ブラシ部材３についても図６に示すようにブラシ部３１１が保持部３１に固着されて交換可能であり、常に新規な状態を維持することができる。
このように、本実施の形態では、振動発生手段１１を内蔵した１つのケース本体１を用いて歯間ブラシ部材２と歯ブラシ部材３の両方を選択して使用することができるのできわめて経済面で有利であり、殊に歯間ブラシ部材２をケース本体１の先端に配置するとともにこれを歯ブラシ部材３により取り外し可能に被せる殊にしたので歯間ブラシと歯ブラシを兼用することができることできわめて便利である。
特に、歯間ブラシ部材２をケース本体１のほぼ中心軸に沿って配置可能としたことによりケース本体１の径を増やすことなしに歯ブラシ部材３を被せることができるので、嵩張ることもない。
更に、本実施の形態では、保管時および携行時には、歯間ブラシ部材２の部分を図１、図２（ａ）に示すように、歯間ブラシ部材２をケース本体１の軸線に合わせた状態として図４および図５に示すようにケース本体１の先部に歯ブラシ部材３を被せた状態とすることにより、歯ブラシ部材３を、歯間ブラシ部材２を配置したケース本体と一体的に保持させているので部品点数も少なく、携行や保管にも便利である。
また、本実施の形態では、図１および図７に示したように、前記ケース本体１の先端に歯ブラシ部材３を嵌装させた状態で取り外し可能に筒状キャップ４が嵌装されている。
そのため、通常は図７に示したような筒状キャップ４を被せた状態で保管、携行する。殊に、本実施の形態では筒状キャップ４の頂面に水抜き孔４１を形成したので、使用後に筒状キャップ４を被せて倒立させた状態で保管しておくことによりブラシに付着している水分を流出させることができる。
図８は前記図７に示した筒状キャップ４を使用時にケース本体１の基部に取り付けた状態を示すものであり、外した筒状キャップの置き場所が不要であるだけでなく、ケース本体１の長さを伸ばして掴み易くすることができるのでケース本体１の長さを短くして全体を小型化することもできる。Next, the best mode for carrying out the present invention will be described with reference to the drawings.
