Abstract

图1中的牙刷包括牙刷主体(12)和刷头组件(14)，该刷头组件包括手动刷毛簇区(16)和在手动刷毛区的前端的单个/少量多个刷毛簇(18)。单个或者多个刷毛簇在牙齿的方向上被轴向驱动并且适合于清洁牙齿的齿间区域。

Description

具有电力驱动的单簇的手动牙刷
技术领域
本发明主要涉及牙刷，并且更具体地涉及一种具有刷毛区的牙刷，该刷毛区具有手动和电动驱动部分两者。
背景技术
常规手动牙刷(其中刷毛区为静态并且被固定到刷头)通常不产生有效的齿间清洁，即在相邻牙齿之间的齿间区域的清洁。这在即使牙刷具有在相邻牙齿之上紧密配合的刷毛尖端配置时仍然如此。在龈线清洁牙齿也通常并不很理想。另外，即使当刷毛被配置成在相邻牙齿之上配合以提供对刷毛覆盖的牙齿表面的更有效清洁时，用户仍然经常难以确定牙刷在牙齿上的正确位置以利用特殊刷毛尖端配置。
发明内容
因此期望具有一种具有刷毛区的牙刷，该刷毛区包括用于实现擦洗牙齿的暴露表面的常规部分，但是也包括将被特殊适配并且有效用于清洁齿间和龈线区域并且有助于在牙齿上恰当定位毛刷的另一部分。
因此，这样的牙刷包括：牙刷主体；刷头组件，包括手动刷毛簇区和单个附加刷毛簇或者少量的多个刷毛簇；以及用于在用户牙齿的方向上朝向和背离刷头组件驱动单簇或者多簇的系统。
附图说明
图1是新型牙刷的一个实施例的简化横截面图；
图2是示出了图1的实施例的移动的端视图。
图3是使用曲轴来驱动单簇的另一实施例的简化横截面图。
图4是使用具有离心装配销的轭状物的另一实施例的简化横截面图。
具体实施方式
参照图1，在10处大体上示出了牙刷。牙刷10包括主体部分12和刷头部分14。刷头部分包括与常规手动牙刷类似的手动刷毛区组件16。手动刷毛区16用来以常规方式擦洗牙齿。刷头部分14也包括受驱动的簇刷毛区部分18，该部分在所示实施例中为单簇，但是可以是组合在一起的多簇。簇18由驱动系统电力驱动，该驱动系统定位于主体部分12内并且延伸通过刷头部分14以与受驱动的簇18连接。
多种驱动系统可以用于受驱动的簇18，下文描述驱动系统的若干实施例。除了描述的驱动系统之外的其它驱动系统在本领域技术内也当然是可能的。在所示实施例中，受驱动的簇18(或者受驱动的簇的小群组)可以与手动刷毛区的前端相邻定位、与手动刷毛区的后端相邻定位或者它可以定位于刷毛区本身内。
受驱动的簇18在尺寸和其它一些特性上一般为常规的(包括在簇中具有近似30根刷毛)。作为例子的刷毛簇可以是直径为1mm-
Figure BPA00001392331100021
mm，但是可以为更大或者更小。簇在横截面上为圆形或者方形或者也可以是其它形状。簇中的单独刷毛通常具有0.006英寸的直径和近似0.40英寸的长度并且由尼龙制成，尽管这可以变化。簇中的刷毛的尖端可以被配置成点或者其它布置以便更好地配合到牙齿区域的齿间和龈线区域中。
图1和图2示出了用于受驱动的簇的一个离心质量驱动实施例，其中离心元件23通过马达31围绕旋转轴30在圆圈中移动。图1的驱动系统包括平坦板簧32，其中刷毛簇装配到的所述平坦板簧。如箭头所示，板簧32被配置成在横向方向上比在上/下方向上明显更硬。这导致受驱动的簇18的主要竖直运动，即在横向方向上的移动跨度相对小并且在竖直或者上/下方向上的移动跨度大。在图2中用旋转质量23、弹簧32和刷毛簇18示出了旋转马达轴杆相对于板簧的动作。
在所示实施例中，簇18的行程近似为4mm长。然而在行程结束时，簇的尖端19必须充分延伸超出手动刷毛的尖端21，使得用户可以感觉受驱动的簇18在他们的牙齿上的轴向运动(轻敲)。基本上朝向和背离牙齿的这一轴向运动对齿间清洁是有效的并且对龈线清洁也是有用的。另外，它对相对于刷头在牙齿上的位置对牙刷进行定向可以是有效的。簇18可以相对于手动簇区定位成使得当牙刷定位成使得簇18碰撞齿间区域(这可以易于为用户所感觉)时手动刷毛区在用于擦洗两个相邻牙齿的外表面的恰当位置。手动牙刷刷毛区还可以使其刷毛尖端被配置成在两个相邻牙齿周围配合。
图3示出了驱动系统的另一实施例，其中马达40驱动曲轴42，在该曲轴的末端装配了受驱动的单簇或者多簇44以实现齿间清洁。曲轴42产生簇的轴向运动。
图4示出了又一实施例，该实施例包括马达49和在马达轴杆52上的离心销50，该销如箭头所示竖直地驱动轭状物54。轭状物54装配到枢轴56，使得该动作产生单簇58的轴向移动。
图1至图4的实施例旨在示出用于产生单簇的简单轴向运动的多种布置。应当理解其它类似驱动系统可以用来产生单簇的期望的轴向运动。
虽然已经出于示例的目的而公开了本发明的优选实施例和替代实施例，但是应当理解，可以在实施例中并入各种改变、修改和替换而不脱离由所附权利要求限定的、本发明的精神实质。
