Description
技术领域
本发明涉及一种牙刷,其带有强化的清洁刷头。
背景技术
牙刷通过从牙齿表面清除牙斑和残渣来清洁牙齿。传统的牙刷设有平面的刷毛齐边,这样就限制了其适合牙齿曲面的能力,难以进入牙齿之间的牙间区进行清除牙斑和残渣和沿牙龈线进行清理。此外,这样的牙刷只具有有限的保持牙粉或牙膏进行牙齿清洁的能力。在刷牙过程中,牙粉或牙膏通常通过刷毛束滑动,脱离刷毛和牙齿之间的接触区。其结果是,牙粉或牙膏通常散布在口腔中,而不是集中到刷毛和牙齿的接触区。因此,清洁过程的效率降低。
发明内容
本发明涉及一种牙刷,其带有新颖的清洁件排列,可提供强化的牙齿清洁。
在本发明的一个方面,牙刷包括刷头,具有多个从基体表面延伸的牙齿清洁件。牙齿清洁件形成环状排列,以更好地保持牙粉或牙膏,接近刷毛和牙齿之间的接触区,进行更有效的清洁。在一个优选结构中,各环状由多个独立的柔性清洁件组成,可使使用者感觉舒服,并提供了改进的牙齿清洁。
在本发明的另一方面,其他清洁件设置在形成环状的清洁件中。在这种结构,这些中心清洁件是关键设置,可使得保持的牙粉或牙膏的清洁效率最大化。
在本发明的另一方面,牙齿清洁件沿刷头的周边设置。在一优选实施例中,这些周边清洁件具有台阶和倾斜,可沿牙龈线进行清洁,和到达牙齿之间的牙间区。
本发明还涉及位于单个刷头上不同种类的清洁件的组合,共同形成可提高牙齿清洁的图案,包括有效地清洁后牙(rear teeth),牙齿之间的牙间区,牙龈线,和牙齿的舌侧和面侧表面。
附图说明
通过参考下面结合附图所作的说明,可对本发明及其优点有更全面的了解,附图中类似标记代表相同的特征,附图中:
图1是根据所显示的实施例的一个或多个方面的牙刷的透视图;
图2是图1牙刷的刷头部分的放大正视图;
图3是图1牙刷的刷头部分的放大侧视图;
图4是沿图2的剖面4-4的刷头部分的截面图;
图5是类似图4的刷头部分的局部截面图,清楚地示出隔离开的牙齿清洁件;
图6是类似于图4的刷头部分的局部截面图,清楚地显示了隔离开的另一牙齿清洁件;
图7是图1所示牙刷的刷头部分的远端视图。
具体实施方式
图1至7示出了具有支承体101的牙刷100,支承体包括手柄103和刷头105,以及清洁使用者牙齿的牙齿清洁件200。手柄103使得使用者容易把握和操纵牙刷100,手柄可形成许多不同的形状和各种不同结构。刷头105是支承体的端部,其上设置了牙齿清洁件200。牙齿清洁件可通过任何已知的方式连接到刷头105的基体表面109。
在优选结构中,基体表面109设有至少一组清洁件209,共同形成环状结构214,可更好地保持牙粉或牙膏于牙齿清洁件200之中,尤其是位于清洁件和牙齿的接触区之间。尽管环形结构最好是圆形,也可以具有各种不同的封闭环状,包括但不限于,椭圆、正方形和不规则形状。相信使用环状内的内凹壁表面将能够更好地保持和移动牙粉或牙膏于牙齿,尤其当牙刷以希望的小圆移动进行刷牙时。此外,还可以使用其他形状。环状可简单地形成基本闭合结构,以保持牙粉或牙膏。
为了更好地保持牙粉或牙膏,各环状结构最好由弹性壁状件组成的清洁件来形成。尽管环状结构可通过紧密安装的细长的刷毛束来形成,但与弹性壁状件相比,这样设置使得牙粉或牙膏脱离的更多。此外,尽管环状结构可以是完全闭合结构,但最好是基本闭合,由多个独立的柔性件209a-d形成。通过这种方式,清洁件能够提供受限和受控的牙粉或牙膏流动于外清洁件,并保持足够的柔性,使使用者感到更舒服,改进清洁件209的清洁作用。在优选实施例中,如图2所示,各环状结构由四个弹性壁状件209a-d形成,各壁状件形成弧状部分,近似于1/4圆。如上所述,临近的弧状部分间隔开,形成间隙212,允许牙粉或牙膏有限地向外流出,允许各个壁状件独立进行挠曲。间隙还可通过水流过环状来帮助清洗清洁件209。但是间隙最好保持细小,以限制牙粉或牙膏的脱离。尽管已经显示出形成环状的四个部分,其他数量也可采用。壁状件可用任何已知可用作牙齿清洁件的弹性材料形成。最后,虽然弧形部分最好是独立的清洁件,环状还可以由单件形成,其上设置槽以形成间隙212,和可独立挠曲的清洁件209a-d。
如图2所清楚显示,优选实施例包括三个环状214a-c,分别沿纵轴线a-a从前到后设置。通过这种方式可保持大部分施加到牙齿清洁件的牙粉或牙膏,以清洁使用者的牙齿。然而,可使用一个,二个或不止三个环状。此外,环状可以其他图案设置,包括非对齐排列或偏离轴线a-a设置。
在优选的结构中,中心清洁件207设置在各环状214的中心。尽管多于一个中心清洁件207也可在使用大环状时设置在各环状中心处。通过这样设置,牙粉或牙膏在刷牙操作期间保留在清洁件207的端部附近进行有效的清洁。在优选结构中,清洁件209a-d的内侧表面的凹进性质在刷头105的刷动或振动期间引导牙粉或牙膏到清洁件207a-c。
中心清洁件207最好由刷毛束形成,以有效地清洁牙齿。但是可使用一个或多个弹性件形成远端清洁件,来额外设置或代替使用刷毛。
清洁件203的刷毛以及下面将讨论的其他刷毛束最好用尼龙材料制成,可从Dupont公司购买商品名为Brilliance的尼龙材料。但是,也可使用其他材料。牙刷100的刷毛最好是具有圆形截面形状,也可以有其他截面形状。圆形刷毛可使用可从Dupont公司买到的商品名为TYNEX的尼龙材料。圆形刷毛的直径最好为0.007英寸到0.008英寸,或具有其他尺寸,这取决于希望的刷毛清洁作用。牙齿清洁件使用已知的口腔护理产品的制造方法连接到牙刷。
参考图1和图2,另外的外环清洁件211a,211b设置在刷头105的中部区域,通常设置成绕中间环状214b的清洁件209a-d的弧形设置。这些外弧形清洁件211a-d最好由两个相对的弧形清洁件形成,弧形件一般是对称的,位于刷头105的纵轴线a-a的两侧。如图2所示,外清洁件211a-b围绕刷头105中心区的环状清洁件209a-d,以有效地使用刷头的这个空间。在优选实施例中,中心区的环状清洁件209a-d一般同心设置于外清洁件211a-b中。流过环状214b侧面上的间隙212的牙粉或牙膏将被外清洁件211利用。而外弧形清洁件211a,b最好用细长刷毛束形成,以有效地清洁牙齿。可代替刷毛或额外地用一个或多个弹性件形成。
图4到6是刷头105的截面图,显示了清洁件207,209和211优选的长度特征。在此优选的结构中,中心清洁件207a和207c的长度短于形成环状214a,214c的清洁件209,可帮助保持环状214a,c中的牙粉或牙膏,强化对牙齿的舌面和脸面的清洁。清洁件207a,c的第一高度H1与清洁件209的第二高度H2的高度差最好在大约0.20-2.0毫米,也可以有其他变化。中心清洁件207b的高度比形成中心环状214b的清洁件209高,可帮助更好地清洁齿间及清洗臼齿的冠部。清洁件207b的第三高度H3和清洁件209的第二高度H2之间的高度差最好大约为0.20到2.0毫米,也可采用其他变化。尽管这个结构是优选的,可优化口腔中各表面的清洁,如果需要,也可采用清洁件的其他高度变化。例如,中心清洁件207互相可具有相同高度,以及与环状清洁件209具有相同高度,或其高度以不同方式高于或低于环状清洁件。在另一示例中,在牙刷100的U形钉结构中,中心清洁件209的高度可高于环状清洁件209。
刷头105还包括位于自由端107的远端清洁件203a-b。在优选的结构中,两个相邻的远端清洁件203a,203b跨过纵轴线a-a,尽管也可由一个或多于两个清洁件形成。远端清洁件203a-b从基体表面109突出的高度超过其他牙刷清洁件的端部。各刷毛束203a-b的端部共同形成最外清洁表面204,其相对刷头105的基体表面109倾斜。在示例方式中,清洁面204最好相对基体表面109形成大约30度角φ,也可以在10到50度的范围。应当认识到,可以形成其他的角度。远端清洁件203a-b的清洁表面204的延伸和角度最好使得使用者可更好地清洁口腔后面的牙齿。清洁件203a-b还可以用于进入牙齿之间空隙和进入臼齿冠部。最后,如图7所示,最外的清洁表面204最好是向侧面向下倾斜(形成冠状表面),以帮助从牙齿清洁残渣。
周边清洁件205a-c位于自由端附近,沿着刷头105的各侧边108。这些周边清洁件205a-c最好由多个刷毛束形成,刷毛束通常相对纵轴线a-a对称设置。清洁件205a-c位于远端清洁件203a-b的后面及侧面。类似地,周边清洁件215a-c也是相对轴线a-a对称设置,靠近刷头105的近端111并沿着各侧边108。两组清洁件205a-c,215a-c通常互相成镜像,但也可以具有其他结构。远端和近端周边清洁件205a-c,215a-c的结构通常可使使用者沿牙龈线进行清洁,和针对牙齿之间的空隙进行清洁。在所显示的实施例中,各组周边清洁件205a-c,215a-c有三个刷毛束。但是,这些组也可使用多些或少些刷毛束。此外,一个或多个弹性件也可用来形成周边清洁件,代替刷毛或与其一起使用。
如图3所示,周边清洁件205a-c和215a-c的端部从基体表面109突出的长度超过内部清洁件207,209,211的长度。在优选实施例中,两组周边清洁件205,215沿刷头105的两侧108设置。各组周边清洁件包括三个一般为平齐的刷毛束,尽管其他数量的刷毛束也可使用。各组周边刷毛束的中间毛束清洁件205b,215b从基体表面109向外突出超过其他毛束205a,205c,215a,215c。这样设置使清洁件205b,215b沿牙龈线可更深接合牙面,同时用清洁件205a,205c,215a,215c刺激牙龈。此外,各毛束具有倾斜的端部206,216,以改善牙间区和沿牙龈线的清洁。
近端清洁件213a-b位于刷头105的近端111附近。一对刷毛束最好跨过纵轴线a-a,但一个或不止二个清洁件也可形成于刷头的近端。这些近端清洁件213a,b最好由刷毛束形成,但是也可以包括或形成一个或多个弹性件。
本发明的各方面的特征可应用于手动牙刷或电动牙刷。操作中,前面介绍的特征可单独地和/或以组合方式改进牙刷的清洁性能。这些优点还可通过各种清洁件和增效作用来实现。尽管牙刷100的各种特征共同作用可实现前面介绍的优点,应当认识到,单个特征和这些特征的组合可用于得到某些前面提到的优点,而不必采用所有的特征。元件的特殊组合在小型化的刷头空间可实现不平常的清洁效果。
尽管本发明已经参考特定实施例进行了介绍,其中特定实施例包括实施本发明的优选模式,所属领域的技术人员可以对上面介绍的系统和技术作出各种变化和改进。因此,本发明的精神和范围应当认为是广义的,如所附权利要求限定的。
