Description

Toothbrush

The present invention relates to a kind of toothbrush, it has a brush holder and one can be bearing in the disk brush holder front end, the band bristle rotationally, be provided with another second rotating disk parallel substantially with above-mentioned disk leaving the distance that first disk is equivalent to tooth thickness at least, bristle is arranged on these two disks side respect to one another.

The toothbrush that people know most a toothbrush handles and many bunchys are arranged usually is arranged on the bristle of this brush holder front portion, so that manual brushing teeth.

The electric toothbrush of swing of bristle do and/or vibration is also known.Its shortcoming is: swing or vibration are too fast, and frequency is too high, and consequently the cleaning performance to tooth is unsatisfied.Because the front end of bristle does not catch up with this rapid movement, bristle is remained static or almost be static state.Therefore, the cleaning performance of known electric toothbrush cleans not as manual.

West Germany prospectus DE-OS173150 has described a kind of electric toothbrush, and this toothbrush has rotating, as to be with a bristle disk at the front end of brush holder.Toothbrush head, disk is made circular motion more precisely, subsidiary can also the swing.With this toothbrush all crooked dental surfaces, gingival pocket, gingival sulcus and diastema all there is better cleaning effect.Yet its shortcoming is: the jaw face is difficult to clean, and cleaning action itself neither be best.

Disclosed toothbrush has the axle of walking around in swiss patent specification CH-PS69561, is provided with two brushes in a certain distance apart from one another on this.Turning cylinder is driven by flywheel, and brush is done to force to rotate owing to connecting together with turning cylinder.

This toothbrush is except impracticable, and forcing to drive also is a shortcoming.Because forcing to drive all is affected its practicality, cleaning action and the flexibility in mouth.

Task of the present invention provides and a kind ofly begins the described toothbrush of part as this specification, and its uses simple, just can obtain better cleaning effect in very short time.

According to the present invention, the solution of above-mentioned task is: two disks are arranged on the common rotational axis, and can rotate together with respect to toothbrush handles, also are provided with bristle on the turning cylinder, and this part bristle is protruding from the perisporium of axle.

Use toothbrush of the present invention can strengthen very easily in a short period of time to putting in order the cleaning performance of secondary tooth.Simply roll and seesaw in mouth by means of doing on the jaw face, turning cylinder and two disks fixed thereon rotate.By two disks and the upward rotational motion of bristle thereof, tooth obtains best cleaning.

According to the layout of bristle among the present invention, can clean inboard, the outside and the jaw face of tooth simultaneously.Like this, in fact in the same time, the quantity of cleaning tooth is the twice of commonsense method, perhaps spends half the time just can carefully clean jaw face and teeth space but also attach with identical with the tooth number of commonsense method cleaning conversely speaking.These can be finished by the bristle and the brush of certain-length and hardness.In fact, in a procedure, cleaned all surface of tooth simultaneously, or rather, in a definite time, the degree of cleaning of jawbone denture is equivalent to clean with ordinary toothbrush 3 times.By the denture of closing lightly, even might clean all surface of upper and lower jaw denture simultaneously, in a definite time, clean the factor like this even can reach 6.

In order to adapt to different tooth sizes and tooth thickness, the part of disk is made by elastomeric material at least.For example, these disks are rigidity at zone line, and externally fringe region is resilient.Certainly, it can be resilient all also.

In the another kind of scheme, the distance between two disks can be regulated, and therefore can meet the different teeth patternings and the requirement of size.

For easy to use, and be more suitable for physiological conditions in the mouth, littler from the diameter of brush holder disk far away than another disk.Previous disk is advanced along the inboard of tooth.

For toothbrush of the present invention is matched with tooth that will clean or jawbone shape better, above-mentioned two disks are connected with brush holder in the mode that can swing.

This swing can reach with different modes.Two disks or their common axis can be fixed on the round end herein, by means of this round end, might be swung accordingly.

The bristle that is arranged on two disk inboards can be arranged by bunchy usually, and can be fixed on the disk by any-mode.

In order to improve cleaning performance, each disk can be made by a sole piece and an orifice plate, passes one or more bristle in per two holes of orifice plate, and two free ends of bristle stretch out from orifice plate, bristle is fixed on the base plate securely, perhaps is fixed between base plate and the orifice plate.

By this structural configuration, many bristles can be fixed on the disk simply, and at this, the mid portion of bristle is fixed on the base plate, perhaps is fixed between base plate and the orifice plate.This fixing for example available bonding, clamping or other similar approach are finished.

Bristle is arranged in the situation of orifice plate by such plain mode a kind of, the part in hole tilts with respect to turning cylinder at least.Therefore, the position of bristle can cooperate preferably with the surface that will clean, cavity, diastema or the like.

When two disks are fixed on the turning cylinder, and turning cylinder is rotatably mounted to one when being integral on the fixed axis of manufacturing with brush holder, and this turning cylinder is provided with the through hole that passes for bristle.

Can change turning cylinder and two disks like this, where necessary very easily.

Further improve in the structure in the present invention, on the outer edge region of each disk, be provided with some pimple shape protuberances.

These protruding pimples can replace bristle, perhaps as replenishing of bristle existed.When brushing teeth, these protruding pimples can be massaged gum simultaneously.

Two disks can be single piece with the turning cylinder of being with bristle, for example are made of plastics.Obviously, they also can be parts separately.

In effectively structure of the present invention, one or two disk is made up of some single fanning strips, and these fanning strips are separated from each other, and perhaps are joined to one another by intermediate connector.

If two disks all are made of some single fanning strips, this toothbrush divides the cooperation meeting of thread form better.And above-mentioned single fanning strip or sheet metal simply mode are done some from bristle and/or its elasticity aspect and are changed and constitute.For example, fanning strip can alternately be fixed shape and resilient shape.Equally, bristle is not set on each single fanning strip and be provided with bristle and the projection pimple, perhaps only be provided with the projection pimple.Equally also can adopt the bristle density of variation.

The setting that can be separated from each other of each sheet metal sometimes even a tangible gap is arranged between each single parts, is perhaps coupled together by middleware each other.For example can as middleware each fanning strip flexiblely be linked together each other with resilient plastics and/or bonding agent.

Like this, produce the thrust of varying strength by the fanning strip that adopts different structure to arrange.

In another kind of structure of the present invention, arch aspectant, that encircle outwardly that the periphery area of two disks forms each other.

By this structure, tooth can be wrapped well, like this massage that can be satisfied with to gum.The pimple that is provided with projection when its outward flange to be to replace bristle, during perhaps as bristle additional, especially like this.

Below in conjunction with accompanying drawing embodiments of the invention are described.

Figure 10 represents two disks that are made of some single fanning strips in the another kind of structure.

Toothbrush of the present invention has a brush holder (1), and a hole of laying rotating journal (2) is arranged at brush holder top.Axle journal (2) is the part of turning cylinder (3), and above-mentioned turning cylinder is connected rotationally with brush holder (1).Two steps (4 and 5) are arranged on the turning cylinder (3), respectively be provided with a disk (6,7) above them, by the clamping each other that is coupled of shape engagement or active force.As from Fig. 1 saw, the diameter of disk (6) is less than the diameter of disk (7).

Stretch out the bristle (8) of bunchy separately from two disks (6 and 7) side respect to one another.Bristle (8) can be distributed in the inboard four corner of two disks (6 and 7) by a plurality of circles or other modes.Replace bristle (8), perhaps, also be provided with inwardly protruded pimple (9), gum is massaged by these pimples in one or two disk (6,7) perimeter as the replenishing of bristle (8).On turning cylinder (3), equally also be fixed with the bristle (11) that is arranged in the through hole (10).Herein, bristle (11) can be fixed in the hole in any way, and is for example fixing by bonding.Obviously, also can adopt the hole that does not drill through to replace through hole.

As being seen from the cutaway view of Fig. 5, through hole (10) can be as the crow flies or is passed turning cylinder obliquely.When adopting a fixed axis (12) as shown in Figure 4, that fixedly connected with brush holder (1), through hole (10) is arranged in (referring to Fig. 5) on the turning cylinder prejudicially.

As can be seen from Figure 1 and Figure 4, inboard, the outside and the jaw face of tooth (21) that just can be represented to dashed lines in cleaning process clean.Turning cylinder (3) is positioned on the jaw face of tooth (21), and the bristle (8) of two disks (6 and 7) places on the side of tooth.If this moment, toothbrush moved by the jaw face of brush holder (1) along tooth, then rotational motion of turning cylinder generation, thereby two disks (6 and 7) is movement therewith also.In Fig. 1 and the described toothbrush of Fig. 2, in the hole of bearing journal (2), form a kind of bearing arrangement, perhaps or rather, axle journal and brush holder (1) are done relative motion, and in the embodiment of Fig. 4 and Fig. 5, a fixed axis (12) being arranged, turning cylinder (3) moves on this fixed axis.

It can also be seen that from Fig. 4 turning cylinder (3) and as a whole of two disks (6 and 7) are for example made by a kind of plastics that meet the health care requirement.

The bristle (8) of two disks (6 and 7) can be fixed on the disk by any means.Fig. 3 has described a kind of effectively solution, many bristles is fixed on two disks (6 and 7) in simple mode, and seldom several bristles are only arranged in each hole.As shown in the figure, a disk is made up of a base plate (6A) and an orifice plate (6B).The hole is arranged on the orifice plate (6B) in any way.Usually people combine use to per two holes (13), and these holes also can tilt, and the front side of slave plate passes through to rear side.Only have one or more bristle (8) to pass in per two holes (13), two free ends of bristle are protruding from orifice plate (6B).By base plate (6A) is fixedly attached on the rear side of orifice plate (6B), bristle (8) is fixed in the hole (13).This can realize that for this reason, the open area that base plate (6A) is gone up in the hole (13) has groove (14), so that compacter with the method that clamps.

Fig. 6 has described an embodiment of this toothbrush, and turning cylinder (3) links to each other with brush holder (1) by a swinging mounting structure (15).For example, this swinging mounting structure (15) can have a round end (16), and it is supported in the associated hole in the turning cylinder (3), and it is reliable to guarantee that by a relieving ring (17) it connects.As shown in the figure, in such a way, except energy threaded shaft (18) rotates, also can be around swing point (19) swing.

By the rotation of two disks (6 and 7), can carry out desirable cleaning to tooth medial and lateral tooth surface and diastema.Also gum is played massage effect simultaneously.Hardness by determining bristle and length and the distribution of arranging bristle and convex pimple can reach optimal cleaning effect.

The available in case of necessity motor (20) that is arranged in the brush holder (1) of the rotation of two disks (6 and 7) and turning cylinder (3) drives.By means of do not describe in detail on the figure, be positioned at being in transmission connection between motor (20) and the axle journal (2) and realize rotating.

Especially when toothbrush is made electric toothbrush, between toothbrush handles (1) and the toothbrush body formed by two disks (6 and 7) and turning cylinder (3), adopted dismountable connection.Therefore when these component wears after, can be very convenient and replacing promptly.Certainly, in the case of necessary, between axle journal (2) and brush holder (1), corresponding stop device can be set.

Two disks (6 and 7) can be made by elastomeric material, and therefore, the distance between two disks can respective change, and two disks (6 and 7) can be opened by plate in other words.

Go up unillustrated spring assembly by means of figure, disk (6) with and disk (7) between the adjustable mode of distance be arranged on the turning cylinder.

Obviously, if when toothbrush of the present invention is want to use by other mode, as required also can be at the arranged outside bristle of two disks (6 and 7).

Fig. 7 has described another kind of structural configuration of the present invention, and the outer edge zone may of two disks (6 and 7) is another disk towards each other, forms arch by this way.Bristle (8) and/or convex pimple are arranged in the inboard of two disks (6 and 7) in the mode identical with other embodiment, and additional bristle (11) is arranged on the turning cylinder.

Fig. 8 and each self-described of Fig. 9 a disk 6 that constitutes by some single fanning strips or sheet metal (6A).On these single fanning strips (6A), bristle (8) and/or convex pimple have also been arranged.They are gone up the density of installing and distribute at these single fanning strips (6A) can be different.Equally, the shape of these single fanning strips (6A) also can be different with elasticity.

According to Fig. 8, these single fanning strips can flexiblely link together each other by binding agent (22); And press the embodiment of Fig. 9, owing to have gap (23) between each single fanning strip (6A), these single fanning strips are not linked to each other each other, thereby each single fanning strip (6A) work respectively to tooth and gum according to its structural configuration.

Figure 10 has described two disks (6 and 7) that are made of some single fanning strips (6A), and they are another disk towards each other, forms arch, from forming umbrella-shaped structure.In this case, the outer peripheral wall of two disks directly is used for massaging gum in corresponding structure is arranged.

In case of necessity, can not adopt structure as shown in Figure 9, that between each single fanning strip (6A), have gap (23), make these single fanning strips resemble the fan some overlap joint each other but it is arranged to.
