Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a dental plaque removing effect and a massaging effect to periodontium are limited in a conventional ultrasonic toothbrush having an ultrasonic vibrator mounted to the brush part of a toothbrush since ultrasonic waves emitted from the ultrasonic vibrator has a single frequency. <P>SOLUTION: This ultrasonic toothbrush is provided with implanted brushes and a support member for supporting the ultrasonic vibrator. The ultrasonic vibrator is supported by the support member between the brushes at a brush part, and vibrations of two frequencies are emitted from the ultrasonic vibrator. Thus, the dental plaque removing effect and the massaging effect to periodontium are prevented from being limited. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、超音波振動子から２つの振動を照射することにより、歯垢の除去を有効にするようにした超音波歯ブラシに関するものである。 The present invention relates to an ultrasonic toothbrush that effectively removes plaque by irradiating two vibrations from an ultrasonic vibrator.

この種の超音波歯ブラシとしては、歯ブラシのブラシ部分に超音波振動子を装着したものが知られている。 As this type of ultrasonic toothbrush, one having an ultrasonic vibrator attached to the brush portion of the toothbrush is known.

しかしながら、このような超音波歯ブラシは、超音波振動子から照射される超音波は単一の周波数の振動であるため、歯垢除去効果や歯周組織のマッサージ効果が固定されてしまう。

解決しようとする問題点は、単一の振動による歯垢除去効果や歯周組織のマッサージ効果が固定されるのを防ぐことである。 The problem to be solved is to prevent the plaque removal effect and periodontal tissue massage effect from being fixed by a single vibration.

本発明は、ブラシ部分のブラシの間に超音波振動子を支持部材で支持するものであり、さらに、超音波振動子から２つの周波数の振動を照射することにより、歯垢除去効果や歯周組織のマッサージ効果が固定することを防ぐことを特徴とする。 The present invention supports an ultrasonic vibrator with a support member between brushes of a brush portion, and further, by irradiating vibrations of two frequencies from the ultrasonic vibrator, the plaque removal effect and periodontal It is characterized by preventing the tissue massage effect from being fixed.

本発明の超音波歯ブラシは、超音波歯ブラシのブラシ部分にブラシを植設するとともに、超音波振動子を支持部材で支持することにより、ブラシで歯を洗浄するとともに、超音波振動子から発生する２つの周波数の超音波により、歯垢を除去し、又、マッサージを有効にする相乗効果を得られるという利点がある。 The ultrasonic toothbrush of the present invention has a brush implanted in the brush portion of the ultrasonic toothbrush and supports the ultrasonic vibrator with a support member, thereby cleaning the teeth with the brush and generating from the ultrasonic vibrator. There is an advantage that the synergistic effect of removing plaque and effective massage can be obtained by ultrasonic waves of two frequencies.

図１は本発明の超音波歯ブラシの斜視図、図２は図１の超音波歯ブラシの一部断面側面図で、超音波歯ブラシはブラシ部分１と柄部分２からなり、ブラシ部分１にブラシ３が多数植設され、ブラシ３の間に支持部材４が装着され、支持部材４の内面に超音波振動子５が装着されている。 1 is a perspective view of the ultrasonic toothbrush of the present invention, FIG. 2 is a partial cross-sectional side view of the ultrasonic toothbrush of FIG. 1, and the ultrasonic toothbrush is composed of a brush part 1 and a handle part 2. Are embedded, a support member 4 is mounted between the brushes 3, and an ultrasonic transducer 5 is mounted on the inner surface of the support member 4.

又、柄部分２の内部に発振器６及び電源７が装着され、図３に示すように、発振器６は超音波振動子５の厚み方向振動を発生する周波数の出力を超音波振動子５に印加する第１の発振器６ａと、超音波振動子５の径方向振動を発生する周波数の出力を超音波振動子５に印加する第２の発振器６ｂとからなり、第１、第２の発振器６ａ、６ｂの出力は切り替え装置８を介して超音波振動子５に印加される。 Further, an oscillator 6 and a power source 7 are mounted inside the handle portion 2, and as shown in FIG. 3, the oscillator 6 applies an output of a frequency that generates vibration in the thickness direction of the ultrasonic transducer 5 to the ultrasonic transducer 5. And a second oscillator 6b that applies an output of a frequency that generates radial vibration of the ultrasonic transducer 5 to the ultrasonic transducer 5, and the first and second oscillators 6a, 6a, The output 6b is applied to the ultrasonic transducer 5 via the switching device 8.

このように構成した本実施例の超音波歯ブラシでは、ブラシ部分１のブラシ３の高さより支持部材４の高さを低くなるように装着しているので、支持部材４がブラシ３による歯磨きの邪魔にならないように構成され、又、支持部材４に装着した超音波振動子５から交互に所望の時間ごとに超音波振動子５の縦振動と径振動を発生するように、発振器６の第１、第２の発振器６ａ、６ｂからの発振出力を切り替え装置８で切り替えて入力しているので、歯垢の除去においてブラシ３によるブラッシングと併用して大きな効果が得られ、又、歯の周囲の組織のマッサージ効果がその組織の位置の深さ方向を変化させることができる。 In the ultrasonic toothbrush of the present embodiment configured as described above, the support member 4 is mounted so that the height of the support member 4 is lower than the height of the brush 3 of the brush portion 1. In addition, the first vibration of the oscillator 6 is generated so that longitudinal vibration and radial vibration of the ultrasonic vibrator 5 are alternately generated at desired times from the ultrasonic vibrator 5 mounted on the support member 4. Since the oscillation output from the second oscillators 6a and 6b is switched and input by the switching device 8, a great effect can be obtained in combination with brushing with the brush 3 in removing plaque, and the surroundings of the teeth The tissue massage effect can change the depth direction of the tissue position.

なお、上記実施例では、発振器６の第１、第２の発振器６ａ、６ｂから超音波振動子５が縦振動と径振動を発生するように発振出力を印加することにより、周波数切り替え時の突入電力が発生するため、単一周波数に比べて低い駆動電力で超音波振動子５を駆動することができ、又、縦振動においても、±数キロヘルツを自動的に移動させることにより同じ効果を得ることができる。 In the above embodiment, the first and second oscillators 6a and 6b of the oscillator 6 apply the oscillation output so that the ultrasonic vibrator 5 generates the longitudinal vibration and the radial vibration. Since electric power is generated, the ultrasonic transducer 5 can be driven with lower driving power than a single frequency, and the same effect can be obtained by automatically moving ± several kilohertz in longitudinal vibration. be able to.
