Abstract

PURPOSE:To press the ends of brush resinous bristles on the surface of a tooth with a substantially uniform pressure and to prevent unclean parts from being formed by dividing brush resinous bristles and the base part of implanted resinous bristles so as to be independently movable and connecting them to a brush shank. CONSTITUTION:In division parts 1a and 1b of the base part 1 of implanted resinous bristles which are formed by dividing the part 1 into two or more, brush resinous bristles 2 are substantially vertically implanted. In the base part 1 of the implanted resinous bristles, the branch part of the division parts 1a and 1b are thinned. As a result, the division parts 1a, 1b of the base part 1 of the resinous bristles are independently elastically deformed and movable in the direction of the thickness thereof relative to a brush shank 3. The brush resinous bristles 2 are pressed on the surface of teeth with a substantially uniform pressure. The brush resinous bristles 2 in the division parts 1a and 1b can effectively be pressed to the surface of teeth, but not at right angles therewith, and meet an angular change.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual toothbrush and an electric toothbrush, and more particularly to a technique for easily and reliably brushing the back teeth and the back side of teeth.

[0002].

2. Description of the Related Art Conventionally, a bristle bristle implant base portion of a toothbrush is a rigid one body.

[0003]

However, since the bristle bristle implantation base of the toothbrush is rigidly integrated as described above, when the toothbrush is applied to the tooth, only the tips of the bristles are deformed and the tooth surface is uneven. However, there is a problem in that only non-uniform pressure is applied and unpolishing occurs. The present invention has been made in view of such a problem, and an object thereof is to make a simple improvement so that the tip of the hair hits the surface of the tooth with a substantially uniform pressure, and unpolishing occurs. To try to provide a toothbrush that can avoid

[0004]

The toothbrush of the present invention is characterized in that the bristle bristle bristle base 1 for bristle bristle bristle 2 is divided into an independently movable state and connected to the brush handle 3. It is a thing.

[0005]

In this way, the bristle bristle bristle base 1 for bristle bristle bristling 2 is independently movable and connected to the brush handle 3, whereby the split bristle bristle bristle base 1 is independently movable. Then, brush hair 2 against the tooth surface.
Even if it is not applied at right angles, the brush bristles 2 at the divided portion can be pressed with a substantially uniform pressure, and the tooth surface on the back side of the back teeth and teeth can be brushed satisfactorily. This is something that can be done reliably.

[0006]

Embodiments of the present invention will be described in detail below with reference to the drawings. The toothbrush A comprises a brush handle 3, a bristle bristle bristle base portion 1 which is divided into at least two or more and is thin, and a bristle bristle 2 which is bristle-polished substantially vertically to the divided portions 1a and 1b of the bristle bristle bristle root portion 1. ing. According to this embodiment, the bristle bristle planting base 1 is divided into thin portions at the branching portions 1a, 1b, so that the bristle bristle planting base 1 is divided into the brush handle 3 and the split portions 1a, 1b.
Can be independently elastically deformed and moved in the thickness direction (arrow direction), uniformly press the tooth surface 4 with the brush bristles 2 at a substantially uniform pressure, and divide the tooth surface 4 into the divided portion 1a. , 1b
Even if the brush bristles 2 in 2 are not right-angled, they can be satisfactorily applied, and it is possible to cope with changes in angle.

FIG. 2 shows another embodiment, in which the base end of the coil spring 5 is embedded and fixed in the brush handle 3, and the tip of the coil spring 5 is embedded in the divided portions 1a and 1b to divide it. The parts 1a and 1b are independently movable.
FIG. 3 shows a usage state of the embodiment shown in FIGS. FIG. 4 shows still another embodiment, in which the bristle bristle bristle bristle base 1 is formed in a spiral shape having at least double windings to substantially divide the bristle bristle bristle bristle bristle bristle 1 into winding portions 1a, 1b ... And, the bristle bristle bristle bristle bristle bristle bristle 2 is bristle-implanted in a mountain shape so that the inner part of the spiral is located higher. In this embodiment, when the brush bristles 2 of the bristle bristle bristle bristle base 1 are applied to the tooth surface, the spiral divided portions 1a, 1b, ... Both the bath polishing that reciprocates in the length direction of the handle 3 and the rolling polishing that reciprocally rotates in a direction substantially orthogonal to the length direction of the brush handle 3 can both be favorably performed. FIG. 5 shows still another embodiment, in which a mounting piece 6 is extended to the tip of the brush handle 3, and a connecting piece 7 of the mounting piece 6 is rotatably mounted about a screw tool 8 as an axis. The split parts 1a and 1b of the bristle flocking base 1 are attached to both ends so as to be rotatable around the screw tool 8. In such an embodiment, when performing a rolling motion, as shown in FIG.
As shown in (b), by swinging the connecting piece 7 in a seesaw shape, it is possible to operate the brush handle 3 in a staggered manner by applying a force while holding the brush handle 3, resulting in a large toothbrushing area and a burden on the teeth. There is little, and fine brushing can be performed. FIG. 7 shows an electric toothbrushing device to which the toothbrush A of the embodiment shown in FIG.
In addition, the electric toothpaste body 10 can be stored upright, and the replacement toothpaste A can be stored in the charging stand 9. Also in such replacement toothpaste A, the embodiments of the various embodiments described above are implemented, and the brush handle 3 is provided with the connection hole 12 which can be connected to the output shaft 11 of the electric toothpaste main body 10. In the figure, 13 is a power cord, 14 is a rolling switch, 15 is a bus polishing switch, and 16 is an off switch.

[0008]

As described above, according to the present invention, the bristle bristle bristle bristle base portion for bristle bristle bristle bridging is independently movable and connected to the brush handle. It is possible to move and press the bristles of the divided part with a substantially uniform pressure without hitting the bristles at right angles to the tooth surface, and it is possible to brush the back teeth and the tooth surface on the back side of the tooth well. There is an advantage that the back teeth and the back side of the teeth can be brushed easily and surely.
