Abstract

The utility model relates to a novel toothbrush for solving the problem of tooth and gum damage due to fault tooth-brushing methods. The novel toothbrush is composed of a toothbrush handle, a toothbrush head and toothbrush bristles. The utility model is characterized in that the cross section of partial or entire toothbrush bristles is in a non-circular shape without peripheral angles. The cross section of the toothbrush bristles in a non-circular shape is horizontally arranged along the length direction of the whole toothbrush, and the peripheries of the majority or the entire cross section do not have angles. When the novel toothbrush is used for brushing teeth, the cleaning effect is equal to or is superior to that of the existing toothbrush. Brush bristles are easy to bend (or looks like very soft) when the teeth is brushed by a wrong tooth-brushing method, so the teeth and the gum are prevented from being damaged.

Description

Toothbrush

The present invention relates to a kind of improved toothbrush, is the instrument of brushing teeth.

The good method of brushing teeth and being oral cavity cleaning in the daily life, promoting oral health.The instrument of brushing teeth generally is a toothbrush.Common toothbrush is made of toothbrush handles, head toothbrushes, bristles.When brushing teeth, hand-held toothbrush handles is scrubbed tooth, gum etc. with the bristles on the head toothbrushes.

The problem that need to solve is that a lot of people brush teeth with above-mentioned toothbrush and cause the damage of tooth, gum, and is damaged etc. as bleeding gums, gingival atrophy, dental wedge.

Brush teeth and cause damage generally to be owing to select toothbrush improper or/and taked wrong method for brushing teeth.

The all easy damage tooth of the toothbrush that bristles is too hard, that head toothbrushes is too big, making is coarse, gum.In recent years, because hygiene department presents one's view, this class toothbrush has been tending towards stopping to produce.(select the too soft toothbrush of bristles to brush teeth, no doubt be difficult for causing damage, but do not reach good cleaning and health care effect.Should select the neither too hard, nor too soft toothbrush of bristles.）

Method for brushing teeth mainly contains along brush method and cross-brushing method.Be difficult for causing damage along the brush method, and be easy to remove the diastema dirt, thereby be correct method for brushing teeth.The cross-brushing method of mistake is easy to cause damage, this be because the decision of the anatomical physiology characteristic of tooth, gum they to can tolerate along brush, poor to horizontal brush tolerance, not only make horizontal brush and will cause damage, and make horizontal brush and also can cause damage with (thereby bristles is neither too hard, nor too soft to suitable brush method) toothbrush by correct suitable brush method design with the too hard toothbrush of bristles.Now, taking wrong cross-brushing method has been to brush teeth to cause the common cause of damage.

Though Oral Science is advocated along the brush method, hundreds of millions of people only knows or gets used to cross-brushing method that this present situation is difficult to change for the moment, therefore is necessary current toothbrushes is improved.

Cause damage problem in order to solve to brush teeth, the improvement that toothbrush is made has multiple scheme, can be divided into two classes:

1, " tooth brush for health protection " recommended by hygiene department, industrial department is formulated the toothbrush production standard, some factory produces " children's toothbrush ", " old man's toothbrush ", some factory does bristles very smooth, sphere is made with the end face of bristles by some factory, in a word, make the existing good cleaning and health care performance of toothbrush be difficult for causing damage again as far as possible.In fact, brush teeth,, be not easy to cause damage really if can note taking correct suitable brush method with current toothbrushes (removing low-quality goods).Although but selected the toothbrush of these function admirables and what in fact take is wrong cross-brushing method, damage is still and is difficult to avoid.

2, because the common cause that causes damage of brushing teeth at present is to take wrong cross-brushing method, the someone has designed the toothbrush that is difficult to horizontal brush.As " fourth " font toothbrush,, its head toothbrushes almost can't carry out horizontal brush because of being transverse presentation to whole brush length direction.The shortcoming of this class toothbrush is always to take to feel not smoothly that along brush method person the person does not often know that own method for brushing teeth mistake is difficult to select this class toothbrush and take the cross-brushing method.

In a word, prior art causes damage problem toothbrush to be made many improvement for solving to brush teeth, and the damage that causes because of toothbrush is defective is rare purely, but still lacks effective measures aspect the damage solving because of the method for brushing teeth mistake causes.

The common cause that causes damage in view of brushing teeth at present is that hundreds of millions of people takes wrong cross-brushing method, cause damage problem in order to solve to brush teeth, task of the present invention provides a kind of novel toothbrush, the performance of this novel toothbrush cleaning teeth is unlike existing toothbrush poor (even better than existing toothbrush), even and take wrong cross-brushing method also to be difficult for causing damage.

Novel toothbrush is made of toothbrush handles, head toothbrushes, bristles, it is characterized in that:

(1), there are many cross sections to be the acerous non-circular bristles of periphery on the head toothbrushes, the cross section that can be all bristles on the toothbrush all is that periphery is acerous non-circular, also can be that the cross section is arranged on the toothbrush is circular and the acerous non-circular two kinds of bristles of periphery

(2), on head toothbrushes, most or whole cross sections are transverse presentation for the cross section of the acerous non-circular bristles of periphery to whole brush length direction--and " cross section of bristles is transverse presentation to whole brush length direction " is meant by different directions and measures non-circular bristles cross section, be shorter than the maximum length that records in the maximum length that records on the direction parallel with whole brush length direction on the direction vertical with whole brush length direction.

Material mechanics principle can prove: the cross section that is transverse presentation is the acerous non-circular bristles of periphery, along brush the time not flexible (seeming harder), when horizontal brush easily crooked (seeming softer).As long as these bristles are neither too hard, nor too soft along when brush, these bristles are soft and easily bend, be difficult for the damage tooth gum when horizontal brush so.Another benefit is, the cross section of these bristles seems narrow and grow during along brush on the dental growth direction, gos deep into diastema removing dirt easily.The cross section that is transverse presentation is big more for the ratio that the acerous non-circular bristles of periphery accounts in all bristles, the easy more performance of above-mentioned advantage.Like this, brush teeth, as take suitable brush method best certainly, even but take wrong cross-brushing method also to be difficult for causing damage with the toothbrush that meets feature of the present invention.

Be described further below in conjunction with accompanying drawing and embodiment.

Fig. 1, Fig. 2 are the cross section enlarged drawings of two kinds of cross sections for the acerous non-circular bristles of periphery.

Fig. 3, Fig. 4, Fig. 5 respectively are schematic diagrames that meets the toothbrush of feature of the present invention, and the partial enlarged drawing of front view, vertical view, vertical view is arranged among each figure from the top down.Toothbrush of the present invention, bristle can be the pencil distribution on head toothbrushes also can not be the pencil distribution, and for clear, the bristles of drawn toothbrush is bordering on even distribution on head toothbrushes.

" what periphery was acerous is non-circular " form in the feature has multiple, only lifts two examples here.When the cross section of bristles is the ellipse 10 of Fig. 1, be difficult for bending along major axis 11 application of force bristles, easily curved along minor axis 12 application of force bristles.Bristles cross section shown in Figure 2 is parallel lines 20,21 and arc 22, arc 23 smooth connections and surround, and (two arc mid point lines are 24, and parallel wire spacing is 25, and line segment 24 is greater than line segment 25) is difficult for curved along 24 application of force bristles, easily curved along 25 application of force bristles.

The toothbrush of Fig. 3 is made of toothbrush handles 30, head toothbrushes 31, many bristles 32.The cross section of bristles 32 is represented whole brush length direction for periphery acerous non-circular (being the shape of similar Fig. 2 among the figure) along the direction of symmetry axis 34, and direction 35 is vertical with direction 34.The cross section of bristles 32 is transverse presentation to brush length direction 34---and from partial enlarged drawing 36 as can be seen, (if with slide measure) measures the cross section of arbitrary bristles 32, and be short with the maximum length of 35 parallel directions with the maximum length ratio of 34 parallel directions.Free end in bristles is parallel to 35 application of forces (being equivalent to along brush), and bristle is difficult for curved (seeming harder); Be parallel to 34 application of forces (being equivalent to horizontal brush), bristle is curved (seeming softer) easily.And along when brush brush end be easy to go deep into diastema.

The toothbrush of Fig. 4 is made of toothbrush handles 40, head toothbrushes 41, many bristles 42,43, and the direction of symmetry axis 44 is represented the length direction of whole toothbrush, and direction 45 is vertical with direction 44.46, the 47th, partial enlarged drawing.The cross section of the bristles 43 of head toothbrushes near head end (zone 49) is circular.The cross section that the head toothbrushes stage casing reaches near the bristles 42 of shank (zone 48) is periphery acerous non-circular (being oval among the figure), and whole brush length direction 44 is transverse presentation---(if with slide measure) measures oval cross section, and be short with the maximum length of 45 parallel directions with the maximum length ratio of 44 parallel directions.The free end of the bristles 42 regional 48 is parallel to 45 application of forces (being equivalent to along brush), and bristle is difficult for curved (seeming harder); Be parallel to 44 application of forces (being equivalent to horizontal brush), bristle is curved (seeming softer) easily.Parallel 45 directions along when brush brush end be easy to go deep into diastema.Put forth effort maximum during because of the horizontal brush of head toothbrushes stage casing bristles, this design can reduce the toothbrush injury rate greatly.

The toothbrush of Fig. 5 is made of toothbrush handles 50, head toothbrushes 51, many bristles 52,53, and the direction of symmetry axis 54 is represented whole brush length direction, and direction 55 is vertical with 54.56, the 57th, partial enlarged drawing.The cross section of the bristles 52 in head toothbrushes stage casing and nearly shank (zone 58) is transverse presentation for peripheral acerous non-circular (being oval among the figure) and to whole brush length direction 54---and short with the maximum length of 55 parallel directions in the bristle cross section with the maximum length ratio of 54 parallel directions.The free end of the bristles 52 regional 58 is parallel to 55 application of forces, and bristle is difficult for curved; Be parallel to 54 application of forces, bristle is easily curved ... be equivalent to along when brush bristle hard, bristle is soft during horizontal brush.The cross section of the most of bristles (bristles 53) in head toothbrushes near head end zone 59 is circular; Nearly symmetry axis 54 places have some cross sections to be the acerous non-circular bristles 52 of periphery, the bristles 52 here, and its cross section does not resemble the cross section of bristles 52 in zone 58 and is transverse presentation to 54, but is " perpendicular position " to 54.When some people places toothbrush in the mouth vertically, along the brush front tooth when inboard, the free end that these cross sections are the bristles 52 of " perpendicular position " gos deep into diastema easily and removes dirt with head toothbrushes near head end bristle.
