Abstract
The invention provides a toothbrush (10) having a handle (12) and a plurality of tufts of bristles (26) secured to the head (14). One of the tufts is secured to the head (14) at a location such that no other tuft is secured to the head at a location that is more distal from the handle (12) than the location where the one tuft is secured to the head (14). The one tuft is angled by about 81 degrees or less relative to an imaginary line which is tangent to a co-planar with a surface of the head through which the one tuft secured to the head. The one tuft is tilted away from the handle towards a direction along which the head extends from the handle.
Description
The present invention relates generally to the oral health field, particularly relate to toothbrush.More particularly, the present invention relates to have the toothbrush of three-dimensional bristle profile, with the cleaning of the fringe region of the mutual approaching zone of tooth that improvement is provided and gums.
Brush teeth with the teeth space backguy is the basic steps of the good oral hygiene of realization.Unfortunately, the teeth space backguy does not obtain accepting extensively of common people, although common people know that the teeth space backguy should be done, with its part as good oral hygiene.And, even the people that do the teeth space backguy often can not carry out the teeth space backguy in unapproachable zone fully in the oral cavity.Unfortunately, the toothbrush of most commercial is the outer cheek surface of cleaning teeth fully, but can not be from gingival edge, zone near each other, and spot and residue are removed in unapproachable zone in tongue surface and other oral cavity.
The reason that such toothbrush can not be removed aftermost molar (for example wisdom tooth or second molar teeth) fully is that one or more brushing cluster away from the toothbrush handle position that is fixed on toothbrush head is not the direction angulation that extends towards head from handle.Therefore, these brushing clusters can not extend enough far away, exceed the head of toothbrush, fully the molar of oral cavity cleaning back.
In addition, those have some brushing clusters towards the handle angulation and other brushing clusters in toothbrush away from the direction angulation of handle, length is identical basically for these all brushing clusters, also has same cross section.And because same length, spacing and the cross section of brushing cluster, when the brushing cluster of these angulations can be with satisfactory way cleaning teeth a part of, another part of tooth can not sufficiently be cleaned.
And the toothbrush of prior art discloses brushing cluster and has had maximum three kinds of different cross sections.But tooth has the part more than three to need cleaning (for example outer buccal surface, gingival edge, mutual access areas, tongue surface and rearmost molar).Therefore, the toothbrush of prior art can not provide all zone of custom-designed enough various cross section with cleaning teeth.
The present invention is used to overcome one or more above-mentioned problem.In brief,, provide a kind of toothbrush, having comprised: a handle according to one aspect of the present invention; A head that extends from handle; At least three brushing clusters that are fixed on described head, each brushing cluster all becomes an acute angle with respect to an imaginary line, a tangent or coplane in surface of described imaginary line and described head, described brushing cluster is fixed to described head by described surface, wherein two cross section differences in described three brushing clusters, described three brushing clusters tilt and arrangement towards identical direction substantially, described direction be parallel to substantially described handle and substantially towards or away from handle orientations, first of described three brushing clusters has a length, second of three brushing clusters with described first is adjacent and have a length shorter than first length, and the 3rd of three brushing clusters is adjacent with first and have a length shorter than first length.
According to another aspect of the present invention, a kind of toothbrush is provided, comprising: a handle; A head that extends from handle; With a plurality of brushing clusters that are fixed on described head, in the described brushing cluster first is fixed on a position of head, the feasible position that does not have other brushing cluster to be fixed on described head again is more farther than the position described handle of distance that this first brushing cluster is fixed on head, this first brushing cluster is inclined to 81 degree or littler angles with respect to an imaginary line, a tangent or coplane in surface of described imaginary line and described head, described first brushing cluster is fixed on the described head by described head surface, described first brushing cluster is towards an inclination that is parallel to the direction work of described handle away from handle substantially, second brushing cluster of described brushing cluster is towards handle tilt, all bristles of the 3rd brushing cluster of described brushing cluster are with respect to acute angle of described imaginary line inclination, and the second and the 3rd brushing cluster has the cross section that differs from one another.
According to a third aspect of the present invention, a kind of toothbrush is provided, comprising: a handle; A head that extends from handle; With a plurality of brushing clusters that are fixed to described head, three in this brushing cluster each all become an acute angle with respect to an imaginary line, a tangent or coplane in surface of described imaginary line and described head, described three bunches are fixed to described head by described head surface, described three bunches are tilted and arrangement towards identical direction substantially, described direction is parallel to described handle substantially, and substantially towards towards or away from the direction of handle, in described three bunches first has a length, and in described three bunches second is adjacent and have the length shorter than first bunch of length with first; In described three bunches the 3rd is adjacent with first and have the length shorter than first bunch of length; One the 4th a bunch position that is fixed to described head, make that not have other bunch to be fixed to the position of described head more farther apart from handle than described the 4th bunch of position that is fixed to head, described the 4th bunch cross-sectional area be fixed to described head take up an official post what it bunch at least four times big of cross-sectional area.
According to a forth aspect of the invention, provide a kind of toothbrush, having comprised: a head, this head have an anterior free end and a rear section; A handle that is connected to described head; Some brushing clusters, they are on the rear section that vertical row is arranged on described head, described vertical row is along the direction that is parallel to described handle substantially, brushing cluster in one first row free end towards described head on a first direction tilts, and the brushing cluster in one second row tilts towards the second direction opposite with first direction; With an other brushing cluster that is fixed on the anterior free end of described head, this brushing cluster tilts towards described first direction, this other cocooning tool has one first length, the brushing cluster that is positioned on the described head rear section has described first length or one second length, described first length is longer than described second length, the brushing cluster of first and second length is drawn together in each vertical package, and adjacent brushing cluster alternately has described first and second length in one is vertically arranged.
By with reference to the accompanying drawings to the detailed description of preferred embodiment, these and other aspect of the present invention, purpose, feature and advantage will obtain more clearly understanding.
