Fig. 7 is the another kind of grooving perspective view of flute profile shown in Figure 4, and for clarity sake, the brushing cluster of brush nose part is removed;

Fig. 8,9 and 10 corresponds respectively to Fig. 1,2 and 3, is the sectional side view of brush point, and these figure explicit declarations are to obtain several distinct methods that the surface configuration at bristle of the presently claimed invention top adopts;

Figure 11 is the plane of one embodiment of the invention, in order to the effect of explanation brush nose part bristle face when cleaning the slot position with water;

Figure 12 is the end-view of brush nose part shown in Figure 4, and this figure demonstrates when brush teeth in gingival margin and cheek surface, and brush is with the situation at rear portion.

Shown in Fig. 1,2 and 3, the preferred embodiment of the invention comprises a toothbrush 10.This toothbrush can be cleaned gingival margin and slot better with water.In general, this toothbrush comprises long handle parts 12, brush parts 14 and numerous bristle 16.Though the brush holder parts of toothbrush and brush parts can use different materials to make, normally make with an injection moulding of same material.Available brush neck member 18 connects between brush holder parts and the brush parts, but this not necessarily.The cross section of brush neck 18 generally is narrower than brush holder 12 or brush 14.

Toothbrush head parts of the present invention are made up of two parts, brush nose part 20 and brush heel part 22.Brush nose part 20 be on the brush from brush holder that part far away, compare, 22 of heel part of brush are that part of of contiguous handle end on the brush.

A main feature of the present invention is unique local shape that the bristle top presents.This unique local shape be with brush with brush point 20 on different bristle height embody.Therefore, various tuft assembling assembling form can produce the desired effect of cleaning with water shown in Fig. 1,2 and 3, and to be that the inventor is well-designed come out for they.

Fig. 4,5,6 and 7 is end-views of toothbrush brush heel part 22 of the present invention.As previously mentioned, the outstanding feature of brush heel part bristle 24 is to be vertically to go up the groove shapes 28 of aiming at.This groove shapes is preferably V-arrangement, as shown in Figure 4.Certainly, some other shape, the classification V-arrangement finishing as " U " shape (Fig. 5) or each tuft also belongs to the present invention and designs category.

Fig. 6 is the perspective view of brush heel part V-arrangement grooving 28 shown in Figure 4.For ease of showing, the bristle 30 of brush nose part is removed.Depth of groove is preferably about 1/16-3/16 inch, to form angle B.Obviously, the degree of depth of V-shaped groove 28 and width remain unchanged substantially along brush heel part 22 longitudinal lengths.

Fig. 7 is another perspective view of brush heel part V-arrangement grooving 28 shown in Figure 4.For clarity sake, the bristle 30 of brush nose part is removed.Obviously, the degree of depth of groove 28 and width gradually change along brush heel part longitudinal length.Along with V-shaped groove levels off to brush holder 12, its degree of depth and width reduce gradually, form the inclination angle that makes progress with respect to brush 22 brush heel part surfaces.

Fig. 6 and Fig. 7 are used for illustrating preferred embodiment.Some other inclination form, as a kind of shallow-dark-shallow grooving also belongs to design category of the present invention.Facts have proved that the grooving 28 on the brush heel part 22 is particularly suitable for cleaning with water gingival margin 34, as shown in figure 12.

Fig. 8,9 and 10 is the side views corresponding to head toothbrushes shown in Fig. 1,2 and 3.These figure are used for illustrating the bristle and the mutual relation of bristle of brushing on the heel part 24 on the brush nose part 30.Explanation to bristle top form is very crucial, because it is an important feature of the present invention.See from the side, shown in Fig. 8,9,10, can find out the effect of " the brush point tilts " along the bristle top that brush point-brush is followed.This interface forms the angle, and the angle is typically about 0 ° to about 45 °, is preferably about 10 ° to about 25 °.When proceeding to teeth space position 32 along the tooth rear portion, as shown in figure 11, this inclination brush point can make bristle keep darker contacting with tooth.

Fig. 8,9,10 adopts distinct methods to obtain similar bristle top shape.Among Fig. 8, the brush of brush point 20 and brush are same plane with 22.Yet the length of bristle 30 strengthens when trend toothbrush top 36 gradually on the brush point 20.In Fig. 9, brush point 20 and brush also are same plane with 22.Yet the brush nose part that bunch bunch bristle is inserted at an angle brush just can form the angle at the bristle top.Because the bristle top can arbitrarily be repaired, so the angle can be greater than or less than the angle at the sharp tuft hole of brush place.At last, shown in Figure 10, be with intersection that head toothbrushes is curved at an angle alpha, thereby form the bristle apex angles at brush point/brush.The obtuse angle alpha that is curved should be about 115 ° to about 170 °, preferably from about 115 ° to about 170 °.Use these and other some technical method can obtain this bristle top surface shape of the present invention.

Bristle of the present invention must have enough hardness can go deep into and remove the tartar and the dental plaque at slot place.Certainly, bristle is also must be enough soft with deeply and remove gingival margin and dental plaque and unlikelyly cause pain and bleed with tartar.The best rounding of bristle tips.
