Description of the Related Art Heretofore, as a method for preventing tooth decay, it has been widely practiced to apply fluoride to the tooth surface or to use a dentifrice containing fluoride as a component. However, since the pH of the pulp blood in the mouth is 7.8, the pH of the pulp tissue is 7.3, and the pH of saliva is at the 6.8th position, (+) ions move from the tooth surface to the pulp tissue, but ( −) Ions tend to be directed from the pulp tissue to the tooth surface. Therefore, in the mouth,
Fluorine ion, which is the (-) ion, is difficult to penetrate into the pulp tissue and is an environment that is not good for enhancing its use effect.
Conventionally, in order to improve the effect of using fluorine ions, a battery of about 1.5V is put in a toothbrush handle, and a terminal made of a conductive material is installed between the hairs at the tip of the bristle, and the terminal of the battery (- ) A large number of ion toothbrushes (electric toothbrush, current-carrying toothbrush or electronic toothbrush) in which the handle is made of metal and this portion is made (+) electrode have been proposed (for example, Japanese Examined Patent Publication No. 48-27390). Kosho 43-50
92). When brushing teeth with a toothpaste containing fluoride with this ionic toothbrush, an electric current flows from the hand holding the handle toward the tooth surface through the pulp tissue, etc., while the fluoride ions permeate from the tooth surface in reverse. It is well known in the art that these deposits have a great effect on the health promotion of teeth by being deposited inside.

っていた。Further, it is a necessary condition for obtaining a sufficient brushing effect to discard the brush bristle if the bristle tip is spread outside the brush base due to use and to use a new toothbrush. . However, in the conventional ion toothbrush, the handle and the brush part are integrated, or the handle and the brush part are separated but the brush part itself is made of a conductive material. Since the conductive material is placed between the brush-implanted surfaces and the structure is extremely complicated, it is too expensive to discard and frequently replace each with a new one, which is a serious obstacle to its spread. .

止される。The spindle 2 is a good conductor of electricity. A small hole 17 extending upward in the radial direction from the support shaft 2 is provided in the handle 1 in the vicinity of the base end of the support shaft 2 on the handle portion side, and a good conductor spring 16 is arranged in contact therewith. A flat disk-shaped battery 15, for example, a lithium battery is placed on the spring 16, so that one end of the support shaft 2 is connected to one electrode of the battery 15, for example, the (-) electrode. The spiral spring 31, the battery 15, and the spiral spring 3 are further provided on the upper end surface of the battery 15.
1 are arranged in order, and these are housed in an inner hole 26 extending upward from the support shaft 2 in the radial direction and opening on the upper surface of the handle 1. The back surface of the end body 14 as the first conductive member is brought into contact with the upper spiral spring 31. This end body 14
At the position covering the opening of the bore 26, each spring 16,
It is fixed so as to resist the pressure of 31 and substantially wrap the outer circumference of the handle part 1 with a part of the bottom face left. Thereby, the end body 14
Is connected to the other electrode of the battery 15 connected in series, for example, the (+) electrode, and the battery 15 is hermetically housed. Both batteries 15 are housed in an inner hole 26 connected to the small hole 17 via an insulating sheet 32 having an annular shape and containing the spring 31. An insulating sheet 32 is similarly interposed between the upper battery 15 and the end body 14. In addition, these batteries 15 are liquid-tightly sealed at the outer periphery of the upper portion by an O-ring 24, and the O-ring 24 is the upper surface of the handle portion 1 and the inner hole 26
Is fitted in the annular groove 27 formed around the opening of the end body 1

８と連通する。符号１３は水切り用のフランジである。By accommodating the disk-shaped battery 15 in the handle so that its flat surface is substantially parallel to the axis of the support shaft 2, that is, substantially parallel to the longitudinal direction of the handle, a flat surface is formed, for example. Compared with the case where the shaft 2 is arranged so as to be orthogonal to the axis, the handle 1 can be made thinner, and the toothbrush can be handled more easily. Especially in this example,
As a recess for accommodating the battery in the handle, an inner hole 26 is provided which is open above the handle and extends in the radial direction of the support shaft 2. The end body 14 is attached to the handle so as to cover the opening of the inner hole 26. Because of the structure, it is possible to freely select the position of the end body in the axial direction of the handle portion, and for example, the end body 14 can be arranged at the position where the user can easily grip it. Further, since the end body is located directly above the battery, no special lead wire or the like is required for electrical connection between the two and the size of the end body can be minimized. Such an advantage is particularly remarkable as compared with the conventional example in which the battery is inserted into the handle portion from the base end surface of the handle portion. The brush head portion 3 is composed of a head portion 20 on which the bristles 7 are planted and a shank portion 25 integrated with the head portion 20. Shank part 25
A concave end 4 which can be engaged with the convex end 5 of the handle 1 is formed at the base end of the handle, that is, in the center of the right end of the drawing, whereby the brush head 3 is attached to the handle 1 with a moderation feeling. It can be installed against. Reference numeral 6 is a slit provided on the upper and lower surfaces, which gives elasticity when the concave end 4 is engaged with the convex end 5. Particularly in this embodiment, the shank portion 2
5, a support shaft insertion portion 18 is formed along the axial direction from the end of the base end portion to a position near the base end portion of the brush bristles 7, and the brush head portion 3 includes the handle portion 1 as shown in the figure. The spindle 2 protruding from the handle 1 when it is mounted on is received. Reference numeral 10 is a communication groove that functions as a part of an electric passage 30 for electrically connecting the support shaft 2 inserted into the support shaft insertion portion 18 to the brush bristles 7 via a liquid such as saliva. The communication groove 10 extends in the axial direction for a predetermined length from a position separated from the brush bristles 12, and the spindle insertion portion 1
Communicate with 8. Reference numeral 13 is a flange for draining water.

なるものである。The electric path is for electrically connecting the brush bristles 12 and the support shaft 2 which are separated from each other. As shown in this embodiment, when the support shaft 2 itself directly connected to the battery of the handle portion 1 extends into the brush head portion 3, the electric passage 30 has the communication groove 10 as described above. It is effective to include. However, the present invention is not limited to this, and the electric passage can substantially electrically conduct the conductive material physically connected to one electrode of the battery and the bristles via saliva. Should be included. Therefore, in this embodiment, the surface portion of the bed 20 existing between the brush bristles 7 and the communication groove 10 is also the electric passage 30. In other words, it is not necessary to dispose the conductive material on the brush bristle transplanting surface or the like so as to be almost in contact with the brush bristle by interposing at least a path connecting with saliva in the electric path between the spindle and the brush bristle. It is a thing.

Exists toward the root. The small groove 8 further promotes the function of the communication groove 10 that electrically connects the support shaft 2 and the brush bristles 7 and 9 via saliva or the like, but is not essential.

よく連結されることとなる。When the brush head portion 3 having the handle portion 1 is put in the mouth and brushing is performed, the brush bristles get wet with saliva moisture, and the moisture also gets into the brush bristles 7, 7. This water is connected to the spindle 2 directly from the roots of the brush bristles 7 and 7 through the surface of the brush head 3, that is, the electric passage 30, or through the small groove 8 if there is the small groove 8.
The water in the communication groove 10 in contact with the water is connected to the water between the brush bristles 7, 7. Therefore, if the teeth come into contact with the tips of the brush bristles 7 ... 7, the support shaft 2 and the teeth can be efficiently connected by sufficient water.
