Description

The present invention mainly relates to a brush tip for removing dirt on the teeth and plaque between gingiva, a toothbrush using the brush tip, and a method for manufacturing the brush tip.

Generally used toothbrushes have a bristles that are flocked at right angles to a flat flocking member. A toothbrush having a brush head with such a configuration is advantageous for sliding the tip of the bristles between teeth, but due to the limited flocking density, a sufficient polishing effect cannot be obtained, There was a problem that it was easy to open and often needed replacement.

Therefore, in recent years, a toothbrush having a configuration in which a disc-shaped brush tip that spreads radially with respect to an axial core is superposed on a cylindrical flocked portion as shown in FIG. 14 (see, for example, Patent Document 1). Thus, the brush head having a cylindrical surface with a high flocking density exhibits a high effect when the tooth surface is polished.

JP 2008-239 A

By the way, in recent years, it has become clear that cleaning of gingival gaps (periodontal pockets) is very important for preventing periodontal disease. It is said that the depth of the periodontal pocket, which is a measure of periodontal disease, is 4 mm, and it is necessary to sufficiently reach the tip of the toothbrush to the back.

However, with a brush head as shown in FIG. 15, when cleaning interdental or gingival gaps (periodontal pockets), the surrounding hair hits the teeth and gums and does not reach the hair tips. In order to cope with this, if the hair tips are pushed strongly into the interdental or periodontal pockets, excessive force is applied to the teeth and gums, which in turn causes them to hurt. Therefore, it is recommended that such a toothbrush be used in combination with other shape toothbrushes to partially polish the mouth. However, it is cumbersome to switch to another toothbrush while brushing.

Further, the manufacture of the disc-shaped brush tip requires a complicated process of fixing each hair bundle after releasing the tips in a radial shape and then welding the central portion. In connection with this, there also exists a problem that the installation cost for performing a processing process will also become enormous.

Therefore, the present invention can provide a toothbrush using a brush tip that is easy to manufacture.

A brush tip according to the present invention is a brush tip of a toothbrush, and includes a group of fibers arranged in parallel in a planar shape, and an adhesive part that collectively bonds and fixes the group of fibers. By providing a step on the outer periphery, the fiber of the step dent portion reduces contact with the tooth periphery, and the fiber tip of the step ridge portion is easy to reach the tooth gap or periodontal pocket.

A toothbrush using a brush tip that is easy to manufacture can be provided.

Embodiments of the present invention will be described below with reference to the drawings.

<Toothbrush and brush tip>
FIG. 1A is a perspective view of a toothbrush 20 according to an embodiment of the present invention, and FIG. 1B is an exploded view of the toothbrush 20.

As shown in FIGS. 1A and 1B, a toothbrush 20 includes a plurality of peripheral step brush tips (hereinafter abbreviated as brush tips) 1 and a rod-like support member on which the brush tips 1 are mounted. 2 and a tip fastening member 3 for fixing the brush tip 1 to the support member 2.

The brush tip 1 includes a horizontal fiber bundle 1a in which bristle brush materials (hereinafter referred to as fibers) are arranged in a substantially parallel plane, and a plane in which the substantially parallel fibers overlap a plane formed by the horizontal fiber bundle 1a. It has a four-blade structure having a vertical fiber bundle 1b arranged so as to be substantially perpendicular to the horizontal fiber. Each wing is rounded and has a gentle convex shape.

Further, the intersecting overlapping portion of the horizontal fiber bundle 1a and the vertical fiber bundle 1b is bonded in a circular shape to form an adhesive region 1c. A circular through hole 1d is provided in the center of the adhesion region 1c. The detailed manufacturing process of the brush tip 1 will be described later.

In addition, the shape of the brush tip 1 is not limited to the above, and may have any shape as long as fibers arranged on a plane are collected. A specific example will be described later.

In the brush tip 1 having such a configuration, a step is generated between the intersecting wings, and a step is formed in the outer periphery of the fiber. Such a fiber in the step dent portion reduces contact with the periphery of the tooth, and the fiber tip of the step ridge portion easily reaches the tooth gap or periodontal pocket.

The support member 2 includes a head A having a round bar shape for passing through the through hole 1d of the brush tip 1, a handle C as a handle, a neck B connecting the head A and the handle C, (Hereafter, the neck B and the handle C are collectively referred to as “main body”). A step D is provided between the head A and the neck B so that the brush tip 1 does not move from the head A to the neck B, and the cross section of the neck B is more than the through hole 1d. It is formed to have a large diameter. It is good also as a structure which provides the latching member for latching the brush tip 1 instead of the level | step difference D. FIG. Further, the handle C is provided with a groove in the neck B side surface to prevent the user's finger from slipping and moving to the neck B side. A member having a high friction coefficient may be attached separately.

The tip fastening member 3 is melt bonded to the tip of the head A in order to prevent the brush tip 1 from coming off the head A after the brush tip 1 is mounted on the head A. Therefore, the tip fastening member 3 has a larger diameter than the through hole 1d. In addition, although the front-end | tip fastening member 3 is good as a desired shape, it is desirable that it is a shape (for example, spherical shape) which does not damage the intraoral area. Further, the head of the head A may be melted and stopped without using the front end fastening member 3.

With such a configuration, the toothbrush 20 according to the present invention can be cleaned by wrapping one by one in accordance with the curved surface of the tooth by providing a step on the peripheral surface. Moreover, as shown in FIG. 14, since the wing | tip of the brush tip 1 enters into gaps, such as between teeth and a periodontal pocket, not only the tooth | gear surface but it does not leave to polish in a narrow space, and high cleaning efficiency is obtained.

<Manufacturing method of brush tip>
Next, the manufacturing method of the brush tip 1 is demonstrated in detail.

2A to 2D are explanatory views showing the manufacturing process of the brush chip 1, and FIGS. 3A to 3D are transition diagrams showing the manufacturing process of the brush chip 1 by the bonding apparatus 100. FIG.

3 (a) to 3 (d), a fiber winding reel 101a on which a horizontal fiber sheet in which horizontal fibers are arranged in parallel is wound and a vertical fiber sheet in which vertical fibers are arranged in parallel are wound. Fiber winding reel 101b, a support base 102a that supports the vertical fiber sheet sandwiched from above and below, a support base (not shown) that also supports the vertical fiber sheet, and a horizontal fiber sheet that moves from above and below, Presser 103a that pulls out the sheet, presser (not shown) that similarly pulls out the vertical fiber sheet, cutter 104a that cuts the horizontal fiber bundle, cutter (not shown) that also cuts the vertical fiber sheet, groove 105a that supplies the molten adhesive, fiber Heater 1 that promotes melting 5b, the punch 105c for performing drilling, a bonding head 105 provided with, and a bonding table 106 bonding head 105 is pressed, the.

The horizontal fiber sheet and the vertical fiber sheet are drawn so that both fibers are substantially perpendicular to each other. Any punch 105c may be used depending on the desired shape of the through hole 1d. Similarly, the shape and cutting line of the cutter 104a vary depending on the finished shape of each blade of the brush tip. Moreover, although the cutter is a blade here, you may use a heat ray, a laser, etc.

Furthermore, the structure of the bonding apparatus 100 is not limited to the above, and the number and position of the bonding head, reel, and the like can be changed as appropriate depending on the number and shape of the fiber bundles used in the brush tip.

A method for manufacturing the four-tip brush tip 1 using such a bonding apparatus 100 will be specifically described below.
(1) First, the support base 102a opens the lateral fiber bundle 1a, and the presser 103a pulls out the lateral fiber sheet on the bonding base 106 (FIGS. 2A and 3A). After that, the support base 102a supports the horizontal fiber sheet again.
(2) Next, a support base (not shown) opens the vertical fiber sheet, and the presser pulls it out onto the bonding base 106 with the vertical fiber sheet interposed therebetween. At this time, the horizontal fiber bundle 1a of the horizontal fiber sheet overlaps with the vertical fiber 1b of the vertical fiber sheet substantially perpendicularly and overlaps (FIG. 2 (b), FIG. 3 (b)). Then, a support base (not shown) supports the vertical fiber bundle 1b again. It should be noted that this process is not necessary when manufacturing a two-blade brush tip 13 to be described later.
(3) The bonding head 105 is lowered to the intersection where both fibers cross, and the molten adhesive is provided from the groove 105a. Further, the horizontal fiber bundle 1a and the vertical fiber bundle 1b are heated by the heater 105, and the intersecting and overlapping portions of both fiber bundles are melt bonded. Thereafter, the punch 105c punches out substantially the center of the bonding region 1c to form a through hole 1d (FIGS. 2 (c) and 3 (c)).

In this case, the fiber bundle is melt-bonded by the adhesive and the heater, but an adhesive effect may be obtained by melting the fiber only by the heater, or the fiber bundle may be bonded only by the adhesive. good. Further, the adhesive members may be stacked and melt bonded.
(4) Finally, the cutter 104a and a cutter (not shown) cut off unnecessary portions of the fiber and cut each wing into an arbitrary shape (FIGS. 2 (d) and 3 (d)).

Thus, the brush tip 1 can be manufactured by the bonding apparatus 100 having a simple configuration.

Note that a plurality of brush tips can be manufactured at a time by using a bonding apparatus provided with a plurality of bonding heads as described above.

For example, as shown in FIG. 4, a plurality of horizontal fiber bundles 1 a and vertical fiber bundles 1 b are arranged, and a plurality of bonding heads are melt-bonded at a plurality of crossover portions of each fiber bundle at a time. Thereafter, the fiber is cut with an arbitrary cutting line to cut out each brush tip, and further, unnecessary portions of each wing are cut off, whereby a plurality of brush tips are completed by a single bonding operation.

Moreover, you may use the method as shown to Fig.5 (a)-(f). FIGS. 5A to 5F are explanatory views showing a manufacturing process when manufacturing a plurality of brush tips from one fiber sheet. This will be specifically described below.
(1) A lattice-like fiber sheet 10 is prepared in which longitudinal fibers arranged so as to be perpendicular to the transverse fibers are spread on the transverse fibers arranged on a plane (FIG. 5A). Although not shown here, the fiber sheet 10 may be fixed by stopping the outer periphery of each fiber with a frame. Further, the fiber sheet 10 may be a net-like one in which both fibers are knitted.
(2) Using a bonding apparatus provided with a plurality of bonding heads, melt bonding and punching are performed at predetermined intervals to form a plurality of bonding regions 1c and through holes 1d (FIG. 5B).
(3) The fiber sheet 10 is cut by a cut line divided into sections of a desired size centering on the through hole (FIG. 5 (c)) to obtain a chip 10a (FIG. 5 (d)).
(4) Unnecessary transverse fibers 11a and longitudinal fibers 11b that are not melt-bonded are scraped from the cut chips 10a (FIG. 5E).
(5) Finally, the unnecessary part of the fiber is cut off with a cutter and each wing is cut into an arbitrary shape to obtain the brush tip 1 (FIG. 5 (f)).
Thus, according to the manufacturing method of the brush tip concerning this embodiment, many brush tips 1 can be manufactured at once by a simple method.

Here, after obtaining the rectangular chip 10a from the fiber sheet 10, the shape of each wing is adjusted by removing and cutting unnecessary fibers. For example, as shown in FIG. By making the cut line) into the wings of the brush tip 1, unnecessary fibers are removed at the time of cutting, and a brush tip having a desired shape can be obtained directly from the fiber sheet 10. By using such a manufacturing method, it is possible to manufacture brush chips having a wide variety of shapes. With respect to specific examples, modifications will be described below.

<Brush tip modification>
Fig.7 (a)-FIG.7 (i) are figures which show each modification of a brush tip.

FIG. 7A shows a four-tip brush tip 11. The shape of each wing of the brush tip 11 is the same as that of the brush tip 1, but is different from the brush tip 1 in that the adhesion region 1c and the through hole 1d are formed in a square shape (polygon). Thus, since the bonding area is uniform for each fiber by making the bonding region square, it is possible to obtain a stronger brush tip. Further, by mounting the brush tip 11 having such a through-hole 1d on a support member having a square (polygonal) head A having a cross section, each brush tip can be used stably without rotating. A brush head having a uniform wing arrangement and steps can be created. Also, in the case of stacking, it is possible to provide a toothbrush having a uniform wing arrangement with the direction of each wing being easily determined. Examples of use for such a toothbrush will be described later.

FIG. 7B shows a brush tip 12 having a six-blade structure. The brush tip 12 has a structure in which three fiber bundles 12a, 12b, and 12c overlap each other by approximately 60 °. The shape of each wing is a square with no rounded corners. In addition, although the adhesion | attachment area | region 1c of the brush tip 12 is circular similarly to the brush tip 1, you may adhere | attach the hexagonal area | region where three fiber bundles overlap, for example.

FIG. 7C shows a brush tip 13 having a two-blade structure. The brush tip 13 has a two-blade structure including only the horizontal fiber bundle 1a (or the vertical fiber 1b) of the brush tip 1, and the bonding region 1c is formed in a square shape and the through hole 1d is formed in a hexagonal shape. By mounting the brush tip 13 having such a through-hole 1d on a support member having a head A having a hexagonal cross section by shifting by about 60 °, a toothbrush having a brush head composed of six wings can be obtained. Can be configured. Of course, not only six wing arrangements but various shapes of brush head toothbrushes having even wing arrangements can be realized. Examples of use for such a toothbrush will be described later.

FIG. 7D shows a brush tip 14 having a four-blade structure. In the brush tip 14, the horizontal fiber bundle 14a and the vertical fiber bundle 14b are cut into an oval shape and melt-bonded at the center thereof. Thereby, the number of fibers at the tip of the wing is configured to be smaller than that of the brush tip 1, and the fibers can be inserted into a narrower gap. In addition, a long fiber at the center is protected by short fibers on both sides during brushing, and the load on each tip tends to be uniform.

FIG. 7E shows a two-tip brush tip 15. The brush tip 15 is configured by only the horizontal fiber bundle 14a (or the vertical fiber 14b) of the brush tip 14. Here, although the adhesion region 1c and the through hole 1d are square, the shape of the through hole 1d and the head A of the support member and the mounting angle of the brush tip are predetermined as in FIG. 7C. By changing for each number, toothbrushes having variously shaped brush heads can be realized.

FIG. 7F shows a brush tip 16 having a four-blade structure. The brush tip 16 has the tips of the horizontal fiber bundle 16a and the vertical fiber bundle 16b cut into a V-shape, the corners of the wings are configured to have sharper angles, and the fibers can be inserted into a narrower gap. It is. Although not shown in the figure, a two-blade structure including only the horizontal fiber bundle 16a (or the vertical fiber 16b) may be used.

FIG. 7G shows a brush tip 17 having a four-blade structure. The brush tip 17 has a structure in which the horizontal fiber bundle 17 a and the vertical fiber bundle 17 b have an elliptical shape with a short diameter longer than that of the brush tip 14. Therefore, the adhesion region 1c is configured to be large, and the wings are more difficult to open and last longer.

FIG. 7H shows the brush tip 18 in which a plurality of fiber bundles in the same direction are collected. The brush tip 18 is obtained by alternately laminating the horizontal fiber bundle 1a and the vertical fiber bundle 1b in five stages and melting and bonding them at a time. This makes it possible to provide a brush head having a higher density wing arrangement.

FIG. 7 (i) shows a four-tip brush tip 19 made of radial fibers. The brush tip 19 melts and bonds the periphery of the fiber bundle 19a arranged radially to form a circular bonding area 1c and a through hole 1d, and then cuts the fiber into a petal shape to form a four-blade structure. It is obtained by doing.

FIGS. 13A to 13D show further modifications of the brush tip.

FIG. 13A and FIG. 13B show a four-tip brush tip 191 and a brush tip 192 made of radial fibers. The brush tip 191 and the brush tip 192 differ from the brush tip 19 in that the through hole 1d is formed in a square shape (polygon). Such a through hole 1d stabilizes each brush tip without rotating when it is attached to a support member having a head A having a square (polygonal) cross section. In addition, it is difficult for the wing arrangement to be displaced, and a brush tip having a uniform step can be obtained.

The brush tips 191 and 192 differ in the angle of the through-hole 1d with respect to the wings. Therefore, if these brush tips are used together, brush heads having more various wing arrangements can be made. For example, if both brush tips are alternately overlapped, a brush head having eight wing arrays with small steps can be formed.

FIG. 13C and FIG. 13D show a six-blade brush tip 193 and a brush tip 194 made of radial fibers. In the brush tips 193 and 194, the through holes 1d are formed in a hexagonal shape. Similar to the above, both brush tips have different angles of the through-hole 1d with respect to the wings, and by combining these, more various brush heads can be created.

As described above, in the brush tip using the radial fiber, it is possible to provide a wing arrangement having a step in the brush head by cutting the fiber into a petal shape. In the brush head having such a step, the contact of the step dent portion with the fiber around the tooth is reduced, and the fiber tip of the step ridge portion easily reaches the tooth gap or the periodontal pocket.

In the above, the modification of the brush tip of this invention was demonstrated. As described above, a wide variety of brush tips can be manufactured by freely designing the shape and number of each wing, the shape of the adhesion region, and the shape of the through hole. Note that the shape of the through hole may be a polygon (for example, a cross shape) recessed inward. In such a case, the cross section of the head of the toothbrush is similar to the shape of the through hole so as to fit into the through hole. In addition to the above, by changing the number and direction of the fiber bundles and the shape of the bonding region and the through hole, it is possible to provide a wide variety of brush tips and toothbrushes using the brush tips.

Hereinafter, modified examples of the toothbrush using the brush tip as described above will be described.

<Modification of toothbrush>
8 to 12 are perspective views showing modifications of the toothbrush according to the present invention.

FIG. 8A shows a toothbrush 21 using the brush tip 1 and the partition member 4a. The toothbrush 21 is obtained by additionally attaching a partition member 4 a to the head A of the toothbrush 20. The partition member 4a is a washer having a circular through hole, and here, the brush chip 1 is partitioned every three. The number of brush tips to be partitioned by the partition member 4a can be set freely as appropriate.

FIG. 8B shows a toothbrush 22 using the brush tip 11 and the partition member 4b. The toothbrush 22 has a square cross section of the head A, and the brush tip 11 having the rectangular through hole 1d and the partition member 4b having the same rectangular through hole are passed therethrough. Here, the partition member 4b is configured to partition the brush tips 1 every five sheets, but the number of brush tips can naturally be set freely.

FIG. 9A shows a toothbrush 23 using the brush tip 11 and the support member 2a. The toothbrush 23 forms a brush head by passing the brush tip 11 and the partition member 4b having a square through hole through the head A. The partition member 4b partitions the brush tips 11 having different wing lengths every five sheets, and a step is provided in the wing arrangement of the brush head. Here, since the center portion uses a brush tip having a short bristle, it is advantageous when brushing teeth along the outer periphery of the tooth arrangement.

The head A of the support member 2a of the toothbrush 23 has a quadrangular prism shape with a square cross section, but has a two-pronged structure with a cut 2A from the front end side toward the rear end side. In addition, it is desirable that the notch 2A is provided so that the head A is divided into the same shape (square shape) in cross section. Moreover, the front-end | tip fastening member 3a is each provided in two front-end | tips of a bifurcated structure. The front end fastening member 3a has a shape in which a rectangular or cubic piece is cut off to form a slope, and the slope is fixed so as to face outward with respect to the cut 2A.

The distance d ′ in the natural state from end to end of each slope is larger than the diameter d of the through hole of the partition member 4 b and the brush tip 11. Therefore, when the front end fastening member 3a is passed through the through hole, the two pieces forming the through hole come into contact with the inclined surface of the front end fastening member 3a, and the front end fastening member 3a is pressed in the direction of the cut A. At this time, if a force of a certain level or more is applied, the bifurcated structure portion of the head A is in the direction of narrowing the notch 2A until the distance d ′ becomes smaller than the diameter d of the through hole. When the distance becomes d ″, the partition member 4b and the brush tip 11 are passed through the head A, and the front end fastening member 3a is released to return to the natural state again. Thereby, the front-end | tip fastening member 3a suppresses that the partition member 4b and the brush tip 11 come off from the head A arbitrarily. In addition, it is also possible to remove the partition member 4b and the brush tip 11 from the head A by pressing each slope from both sides.

With this configuration, in this modification, the brush tip 11 and the partition member 4b can be freely attached to and detached from the head A. Therefore, the shape of the brush head can be freely changed by replacing these with favorite members. It is possible to exchange what has been damaged.

The mutual relationship between the distances d, d ′, and d ″ is not necessarily limited to the above, and can be appropriately designed depending on the elasticity and plasticity of each member.

FIG. 9B shows a toothbrush 24 using the brush tip 11 and the partition member 4c. In the toothbrush 24, the brush tip 11 and the partition member 4c (warm ring) having a gear structure in which the protruding teeth are parallel to the axis are mounted on the head A of the support member 2a. Of course, the through-hole which the partition member 4c has shall have the internal diameter similar to the said partition member 4b. By using a flexible elastic material (for example, silicon rubber or an elastomer material) for the partition member 4c having such a gear structure, it is possible to obtain an effect that the protrusions scrape dirt between teeth or massage the gums. .

FIG. 10A shows a toothbrush 25 using the brush tip 1 and the support member 2b. The toothbrush 25 includes a support member 2b including a handle portion C, a neck portion B that forms a female screw, and a head portion A that has a male screw that is detachably formed on the female screw. The neck portion B is provided with a screw hole 22B that is screwed with the head portion A, and the rear end side of the head portion A is provided with a screw thread 21B that is screwed with the screw hole 22B. The neck B side may be a male screw and the head A side may be a female screw.

With such a configuration, the toothbrush 25 can make the head A itself detachable from the main body, thereby forming a brush head having a desired shape or exchanging damaged parts.

Also, a minus or plus shaped groove is carved in the tip fastening member 3b provided integrally with the head A as a screw head. However, in the case of a plus shape, a minus shape is desirable because water and dirt easily accumulate in the groove. Further, a hexagonal head with rounded corners may be used.

FIG. 10B shows a toothbrush 26 using the brush tip 1 and the support member 2c. The toothbrush 26 has a hole into which the head A is fitted, a neck B having a latch claw 22C inside thereof, and a notch 21C which is fitted in the neck B on the rear end side and engages with the latch claw 22C. It has a support member 2c composed of a head A and a handle C. Here, the latch engagement between the notch 21C and the latch claw 22C is due to the elasticity of the support member 2c. A notch may be formed on the neck B side and a latch claw on the head A side. With such a configuration, the user can freely attach and detach the head A from the main body of the toothbrush 26 as well.

FIG. 11 shows a toothbrush 27 using the brush tip 13 and the support member 2d. The toothbrush 27 has a support member 2d as a so-called electric toothbrush that includes a handle 21C, a switch 21D, a battery 22D, and a motor 23D. Specifically, the motor 23D obtains a tooth cleaning effect and a gum massage effect by vibrating or rotating the head A or rotating the head A forward and backward.

The head A has a hexagonal cross section, and is mounted with a brush tip 13 having a hexagonal through hole. Here, since the brush tips 13 are shifted by about 60 ° for each sheet and passed through the head A, a six-blade structure brush head having six wing arrangements is formed. According to such a configuration, various shapes of brush heads can be formed depending on the angle and number of the brush chips 13 that pass through. If the head A is configured to be detachable from the main body as in the above modification, it can be used as an electric toothbrush that can be replaced as an attachment when the brush is damaged.

FIG. 12A shows a toothbrush 28 using the brush tip 11 and the support member 2e. The support member 2e is formed in a flat plate in the short direction, and the head A has a hood 21E that covers the brush and two support shafts 23E that extend from both ends of the hood 21E. A shaft hole 26E is provided in the support shaft 23E, and projections 25E formed at both ends of the shaft member 24E are fitted therein to support the shaft member 24E in a rotatable manner.

The shaft member 24E is a prism having a square cross section, and a brush head is formed by passing the brush tip 11 and a partition member (not shown) through the shaft member 24E. The hood 21E has a draining hole 22E.

According to such a structure, a tooth | gear can be cleaned to every corner or a gum can be massaged with a rotating brush tip, without damaging the inside of an oral cavity with a brush.

FIG. 12B shows a toothbrush 29 using the brush tip 1 and the support member 2f. The support member 2f of the toothbrush 29 is different from the support member 2e in that the shaft member 24F is cylindrical in order to use the brush tip 1 having a circular through hole, and the hood is not formed.

According to such a configuration, a brush head smaller than the toothbrush 28 can be realized, and the brush can be delivered to the back teeth.

In the above, the modification of the toothbrush which concerns on this invention was demonstrated.

As described above, the toothbrush according to the present invention can have a wide variety of configurations depending on the combination of the brush tip, the partition member, and the support member.

More specifically, the length, shape, thickness, hardness, color, and the number of brush tips with different tip shapes (spherical or tapered), mounting positions and angles, and the shape of the partition member, Thickness, hardness, color, and shape of the support member can be freely selected and assembled by the user, and the user can freely create a toothbrush tailored to symptoms and preferences.

For example, by alternately using brush tips with different lengths of hairs, a wing arrangement having a step can be realized. Thereby, since the gap | interval of a tooth | gear can be polished in the long part of a bristle and the surface of a tooth | gear is close | similar, efficient cleaning becomes possible. In addition, for example, by attaching brush tips having partially different hardnesses and tip shapes, a brush head that is comfortable to use according to the user's teeth arrangement, symptoms, and preferences can be obtained.

In addition, since partial brush tips and partition members can be exchanged, waste can be reduced by exchanging only damaged parts (for example, brush tips on the end face), and the economy is also excellent. .

In addition, by setting the length of the head A to a multiple of the thickness of the brush tip and the thickness of the partition member, when the user assembles them, the respective members are not loosely mounted on the head A stably. It becomes possible to do.
