The embodiment of a kind of toothbrush of the present invention is described below in conjunction with accompanying drawing.Fig. 1 is the three-dimensional view of this embodiment head, and Fig. 2 is the side direction view of this embodiment, and Fig. 3 is the cross sectional view of this embodiment bristle tufts when implanting state, and Fig. 4 is the three-dimensional view of toothbrush bristle structure of the present invention.
As illustrated in fig. 1 and 2, the toothbrush of present embodiment is by one group of bristle 1,1 ... the tuft that constitutes is implanted one group of slotted eye 21,21 that is arranged at toothbrush head 2 respectively ...The toothbrush of this respect present embodiment has nothing different with traditional toothbrush.
In the toothbrush of present embodiment, as shown in Figure 1,100% bristle 1,1 ... respectively has the square-section that has long limit and minor face.Each bristle 1,1 with square-section ... implant rectangle slotted eye 21,21 ...Rectangle slotted eye 21,21 ... being arranged in it makes a side perpendicular to toothbrush axis L.Tuft is by dull and stereotyped 11,11 ... implant slotted eye 21,21 ... correspondingly, dull and stereotyped 11,11 ... be installed in slotted eye 21 in mode perpendicular to axis L, 21 ... in, and the bristle 1,1 of brush finish by being rendered as out-of-flatness shape as shown in Figure 2 ... the upper surface and determine.
According to the toothbrush of present embodiment, 80% or more bristle 1,1 of sum ... all have the square-section, implant with the angles of long limit, cross section and axis L inclination 80 to 100 degree, and bristle 1,1 ... mix with mineral material.
The toothbrush of present embodiment will be described in more detail.As common toothbrush, the toothbrush of present embodiment comprises implants many bristles 1,1 ... the head 2 of tuft, the shank 4 that grips when being used to use, and a neck that is used for they connections, as shown in Figure 1.
Be implanted to slotted eye 21,21 ... bristle 1,1 ... to this dicarboxylic acid esters (PBT), (6-12,6-10 6-6), constitute in the polypropylene nylon by polybutene.As shown in Figure 1, bristle 1,1 ... sub-thread with square-section with a long limit and a minor face is folding in the middle, and by a flat board 11 fold domain is kept, and dull and stereotyped 11 together is installed in the slotted eye 21.In Fig. 1, for brevity, though only illustrate one bristle, need not superfluous words multiply bristle more, when bristle is implanted, be to have many strands of integrated tufts to be implanted in the slotted eye 21.
The height of bristle 1 (2 upper surface is to the upper end height of bristle 1 from the head) h (see figure 2) is preferably 8mm to 13mm, is 9mm to 12mm better.If highly be lower than 8mm, bristle is difficult to distortion, not only make and remove the colouring power variation, and also variation of massage ability and cleaning capacity.On the contrary, if highly surpass 13mm, bristle can be upset the moving flatness of brush, has again, and its rigidity can become too that weakness makes the removing colouring power, and massage ability and cleaning capacity die down.In fact, implant in the present embodiment head 2 bristle 1,1 ... have different length, the longest bristle is preferably in the above-mentioned scope.
According to the toothbrush of present embodiment, as shown in Figure 2, implant head 2 bristle 1,1 ... have different length, make by bristle 1,1 ... the brush finish of upper end decision see from the toothbrush side and be rendered as the out-of-flatness shape.By the brush finish of this type of out-of-flatness structure of providing, bristle becomes and enters interdental slit easily, and the result makes bristle and interdental contact area increase considerably.In the present embodiment, provide a kind of zigzag out-of-flatness shape.Discrepancy in elevation d between the highest bristle and the minimum bristle is preferably 0.5mm to 3.0mm, is 1.0mm to 2.0mm better.If discrepancy in elevation d is less than 0.5mm, the highest bristle becomes and can not enter between the tooth effectively.On the contrary, if discrepancy in elevation d greater than 3.0mm, minimum bristle becomes and can not contact tooth.
As noted, the cross section of bristle 1 is the rectangular configuration with long limit and minor face.The ratio of long limit, cross section and minor face is preferably 1 to 2.5, is 1.5 to 2.0 better.The long edge lengths in rectangular configuration cross section is preferably 0.2mm to 0.4mm, is 0.25mm to 0.35mm better.If length is less than 0.2mm, it is too weak that the rigidity of bristle becomes, and makes the removing colouring power, massage ability and cleaning capacity variation.Otherwise if length surpasses 0.4mm, bristle becomes and is difficult to distortion, not only makes the removing colouring power, and makes massage ability and cleaning capacity variation.
Be implanted to the bristle 1,1 of head 2 ... sum 80% or be arranged to make between long limit, cross section and the axis L have 80 degree to 100 angle [alpha] of spending.Fig. 3 has illustrated a kind of bristle 1,1 ... implanting state in slotted eye 21 (Fig. 3 middle section line is omitted).Though have clockwise angle [alpha] among Fig. 3, still can be to the scope of 100 degree because of it at 80 degree, it also can have counterclockwise.If the bristle 1,1 in above angle [alpha] scope ... be less than 80%, bristle 1,1 ... and the total contact area between the dental surface will reduce when brushing teeth operation, can not obtain the removing ability that effectively dyes.
If angle [alpha] is less than 80 degree or surpass 100 degree, they too depart from the position perpendicular to axis L.The result is bristle 1,1 ... and the total contact area between the dental surface will reduce when brushing teeth operation, can not obtain the removing ability that effectively dyes.In order to make bristle 1,1 ... sum 80% or have with upper position more, importantly control bristle 1,1 ... implant rectangle slotted eye 21 with dull and stereotyped 11 perpendicular to axis L ground.
Preferably make bristle 1,1 with square-section ... terminal part 12,12 ... be shaped to frustum shaped structure as shown in Figure 4.In the bristle 1 with frustum shaped end 12, frustum shaped end 12 plays the effect of scraper in the operation of brushing teeth when carrying out, make that the grinding agent in the toothpaste puts on dental surface effectively.In addition, because the surface that terminal part 12 has sharpening, it can successfully enter between the tooth, and when toothbrush slides, bristle 1,1 ... tilt, the bacterial plaque between tooth is struck off effectively with the dyeing that is attached on the tooth.
As shown in Figure 1, slotted eye 21 is shaped to the rectangular configuration that comprises long limit and short end (limit), and is arranged in and makes long limit perpendicular to axis L.The length of short end is 0.5mm or longer, and less than 2mm, is preferably 1.0mm or more, and less than 1.5mm.If length less than 0.5mm, can't be implanted.On the contrary, if length surpasses 2mm, be orientated from flat board bristle farthest restive.The last edge lengths of slotted eye 21 is 1.0mm or more and less than 4mm, and is preferably 1.5mm or more, and less than 3mm.If length less than 1.0mm, can't be inserted.On the contrary,, then can not obtain enough implantation density, cause the slip of bristle or come off if length surpasses 4mm.Although can be subjected to the restriction of actual conditions, long edge lengths is preferably 0.25 to 4 with the ratio of short end length, and is 0.5 to 2 better.
The area of slotted eye 21 (bristle implantation area) is 1 to 4mm
2, and be preferably 1.5 to 3mm
2If area is less than 1mm
2, the brush amount in each hole becomes very little, can not obtain enough contacts area.On the contrary, if area surpasses 4mm
2, then can not obtain enough implantation density, cause bristle 1 to be easy to slide or come off.The bristle 1 of an implanted slotted eye 21 is preferably 10 to 40 strands, although what can be determined by the area and the relation between bristle 1 sectional dimension of slotted eye 21.
Slotted eye 21,21 ... preferably be provided with 0.3mm to 2.5mm at interval, and be 0.6mm to 2mm better, as passing through P among Fig. 1
1Shown longitudinal separation.Similarly, as passing through P among Fig. 1
2Shown, the lateral separation is preferably 0.5mm to 4mm, and is 0.7mm to 3mm better.If interval P
1, P
2Surpass 2mm respectively, 4mm, then adjacent brushing cluster mutual alignment is too far away, makes some tooth can not contact bristle.As a result, can not obtain the ability of enough removal dyeing.
In irregular brush finish, the distance P between Fig. 2 protrusions
3And the distance P between the depression
4Be respectively 3 to 12mm, be preferably 4 to 10mm.If distance is less than 3mm, then short bristles 1,1 ... because long brush hairs 1,1 ... bear all supporting roles and do not reached tooth.On the contrary, if distance surpasses 12mm, then long brush hairs 1,1 ... too reduce, will produce bristle 1,1 between tooth ... inaccessible place.
The toothbrush of present embodiment constitutes in the above described manner.According to the toothbrush of present embodiment, bristle 1,1 ... side (with respect to containing the side of long limit) with the long limit of short end moment shape structure cross section in that brush teeth can be sharp keen in operating and flatly contact dental surface.Therefore, can increase the contact area between the two, and tooth dyeing be removed effectively and without any the damage of dental surface.
Because total amount 80% or more implantation rectangle slotted eyes 21,21 ... bristle 1,1 ... the angle that favours axis L is that 80 degree are to 100 degree, nearly all bristle 1,1 ... the side all can contact dental surface effectively, therefore, dyeing removal ability can further be strengthened.Have again, in the toothbrush of present embodiment, because bristle 1,1 ... mixed have mineral matter, when bristle 1,1 ... the contacts side surfaces tooth time, mineral matter polishing dental surface can more effectively be removed the dyeing of tooth.
Toothbrush of the present invention is not limited to above embodiment.For example, in the present embodiment, though irregular brush finish is by bristle 1,1 ... the upper end be defined as shown in Figure 2 zigzag, it also can (see Fig. 5 a), rake shape (seeing Fig. 5 b), or wavy (seeing Fig. 5 c) for the mountain range shape.In above embodiment, slotted eye 21 is four jiaos of rectangular configuration that are the right angle, shown in Fig. 6 a, but also can be the rectangle with four fillets shown in Fig. 6 b.
In above embodiment, slotted eye 21 is shaped to right-angle structure, comprises long limit and short end, and as shown in figs. 1 and 6, the limit of the L that parallels to the axis is short end, but this limit also can be long limit.And slotted eye 21 can be shaped to the square structure with identical length of side.
Though all bristles 1,1 among the above embodiment ... have rectangular cross section, but bristle 1,1 ... be not limited to this structure, as long as bristle 1,1 ... 80% or manyly all have a rectangular cross section that comprises long limit and minor face.For example, 20% or bristle still less 1,1 ... can comprise and have the shaft-like of circular cross section, have the bristle 1,1 of this type of circular cross section ... also has the terminal part 12,12 that preferably is rendered as frustum-like shape ...
Also has bristle 1,1 ... can have the round rectangle cross section structure.
Though bristle 1,1 among the above embodiment ... by dull and stereotyped 11 load holes 21 are implanted slotted eye 21,21 ..., brushing cluster also can be soldered on the head 2.
Among the above embodiment, the upper surface of head 2 is flat.But also can be shaped to stairstepping.Thus, can adjust the elasticity of each several part brushing cluster, feasible dyeing removal ability, massage ability and cleaning capacity can suitably be coordinated.Have, though the Tooth-brush structure among the above embodiment has a handle portion 4 to be easy to use grasped, it also can be shaped to does not have handle portion 4, and the head that can take away is arranged as electric toothbrush again.Under the prerequisite of main points of the present invention, can make other changes in case of necessity.
