By the way, for cleaning by ultrasonic waves, water to be transmitted with ultrasonic waves must be sufficiently filled in the oral cavity.
No. 6, even in Japanese Patent Application Laid-Open No. 6-204, there is proposed a technique for supplying water to an ultrasonic toothbrush by a water pump. However, they have no means of draining the supplied water and, as a result,
For example, a face is put on a wash bowl, brushing is continued while supplying water with the mouth open, and the water flows into the wash bowl as it overflows from the mouth. Therefore, the forward bending posture is cramped, and at the same time, daily brushing is not troublesome, and there is a possibility that the clothes may be wetted. or,
There is a disadvantage that the water in the oral cavity tends to be excessive or too small, and the ultrasonic cleaning effect is not effectively exhibited, and the present invention aims to eliminate these disadvantages.

Water capacity is assumed to be the capacity that can be stored. Further, as shown in FIG. 3, a drain tank 33 for temporarily storing drained water can be provided adjacent to the water supply tank 31 as necessary. And the water tank 3
A pump serving as a starting force for water supply and drainage is connected to the first and drainage tanks 33. There are several embodiments of the pump. As shown in FIGS. 1 and 2, the pressurized side of the pump is connected to the water supply side and the negative pressure side is connected to the discharge side, and one pump 22 serves both water supply and drainage. Desirably in form. However, when two pumps are used due to the difference in the form of the pump, as shown in FIG.

First, in order to use the toothbrush of the present invention, the brush body 15 is connected to the head body 11 and the amount of water necessary for at least one cleaning is stored in the water tank 31 of the water tank section 30. Then, a detergent is attached to the brush body 15 and inserted into the oral cavity, and at the same time, the ultrasonic oscillation circuit 21 and the pump 22
Turn on the switch. Then, water is supplied from the water supply tank 31 through the water supply pipe 41 and the like by the pump 22, and water is supplied from the water supply port 13 of the head 10, and the jetted water fills the oral cavity. When the water supply pump 32 (and the drainage pump 34) is provided in the pump, the switch of the pump is naturally input.

される。At the same time, an ultrasonic wave is generated from the piezoelectric vibrator 12 by the input of the electric circuit 21, and the vibration is generated by the brush 1
5 is finely vibrated. As a result, a frictional action is caused between the tooth and the brush bundle 17 that has come into contact with the tooth, due to micro vibration,
Plaque, food residue, etc. are removed. At the same time, the ultrasonic wave causes cavitation in water, sucks and peels off the dirt attached to the teeth, and disturbs the washing solution, emulsifies, etc.
In addition to the cleaning by the frictional action, a further cleaning effect is promoted.

When the amount of water exceeds a certain amount, the water overflows from the oral cavity and flows down as it is. Therefore, conventionally, the water supply had to be stopped, or the water had to be bent into the wash basin or the like, and the overflowing water had to flow down to the wash basin with the mouth open. However, in the toothbrush of the present invention, since the drain port 14 is formed at the base end of the concave portion 11a of the head 10, the water collected near the drain port is sucked by the suction force from the pump, and the drain pipe 42 is formed.
After that, it is automatically drained to the wash basin.

きる。Therefore, water does not overflow into the oral cavity,
The balance between supply and discharge of water is achieved, and appropriate water is supplied into the oral cavity. Therefore, it is possible to continue washing by water supply and accompanying ultrasonic vibration, and it is not necessary to take a posture that leans forward toward the wash basin at that time, and to maintain a natural posture with the back muscles extended. Can be.

となる等の数々の利点を奏する。According to the present invention as described above, excellent cleaning action by ultrasonic waves can be expected, and plaque removal and periodontal massage effects can be obtained. At that time, the conventional method was to open the mouth and let it flow down to the washstand, etc., so there was no excess or small amount of water in an appropriate amount, and it was not very effective to apply ultrasonic waves,
However, in the present invention, since a balance between water supply and drainage is achieved, an appropriate amount of water exists in the oral cavity, and a truly effective ultrasonic effect can be expected. Also, since the brush body is easy to replace, it can be disposable, it is economical to replace only the consumable part, and the tooth brushing posture does not need to be bent forward, it can be in a natural posture with the back extended. It offers a number of advantages, such as being comfortable.
