Description

电动牙刷
技术领域
本发明涉及电动牙刷。更具体地讲，本发明涉及具有可绕枢轴转动的转轴的牙刷。
发明背景
利用各种传动机构的电动牙刷已为本领域所知。然而，一直期望提供这样一种电动牙刷，其利用可提供机械有效的多重刷毛载体运动的传动机构和/或可提供更小更紧凑的布置。
发明概述
本发明提供了一种电动牙刷。该电动牙刷具有柄部、带有第一和第二刷毛载体和纵向轴线的头部、以及设置在柄部和头部之间的颈杆。马达设置在柄部内部。转轴可操作地连接到马达上。转轴可在左右摇摆的方向上绕枢轴转动并且可操作地连接到第一和第二刷毛载体上，以在左右摇摆的方向上移动第二刷毛载体，并使第一刷毛载体围绕一条基本垂直于头部的纵向轴线的轴线摆动。
附图概述
虽然本说明书已针对本发明的权利要求书作出结论，但相信由下列描述并结合附图可更好地理解本发明，其中：
图1是依照本发明制成的电动牙刷的分解透视图；
图2是图1的电动牙刷的转轴、轴衬和传动齿轮的顶部平面图；
图3是图1的牙刷头部的侧正视图；
图4是图3的头部的顶部平面图；
图5是适于供图1的牙刷使用的头部的另一个实施方案的顶部平面图；
图6是图1中的牙刷的第一刷毛载体的侧正视图；和
图7是图6中的第一刷毛载体的另一侧正视图。
发明详述
下面将说明本发明的多种实施方案，它们的实施例图示说明于附图，其中在所有视图中，同样的数字表示相同的元件。参见图1，下面将描述电动牙刷20。电动牙刷20包括柄部22、颈杆24和头部26。颈杆24可与柄部22整体成型或可作为一个单独组件提供。柄部22具有可螺旋地与柄部22一部分接合的端帽28。电动马达30以及电压源设置在柄部22内部。电压源可以一个或多个电池32的形式提供，电池32安放在设置在柄部22内部的电池槽34中。马达30具有一个可旋转的输出转轴和一个连接到可旋转的输出转轴上的输出齿轮38。输出齿轮38与传动齿轮40啮合，传动齿轮又可操作地连接到转轴42上。转轴42具有一个带有细长狭槽45的联接器44，细长狭槽45与传动齿轮40的偏心柱44啮合。狭槽45与转轴42的纵向轴线对齐。转轴包括一个被柄部22或颈杆24锁位的轴衬46。轴衬46可由使转轴42能够绕轴衬46旋转的任何柔韧材料制成。适用的材料可包括弹性体聚合物，例如天然或合成橡胶。轴衬46起枢轴的作用，转轴42可围绕其运动。轴衬46的位置可沿着转轴42的长度进行改变，以便在转轴42与头部26相邻的末端处获得所需的左右摇摆量。当传动齿轮40旋转时，转轴42在左右摇摆的方向上绕轴衬46转动，如图2中最佳所示。转轴42的左右摇摆运动基本或完全发生在单一平面上。
头部26具有第一自由端48和与颈杆24接合的第二末端50。头部包括一个或多个刷毛载体。所述电动牙刷20包括两个刷毛载体。第一刷毛载体52邻近第一末端48设置，第二刷毛载体54邻近第二末端50设置。第一刷毛载体52围绕基本垂直于头部26的纵向轴线58的轴线56摆动，如图3所示。第二刷毛载体54在左右摇摆方向上往复运动或垂直于头部纵向轴线运动，如图4所示。尽管图4所示的左右摇摆运动基本上垂直于头部26的纵向轴线58，但可以设想，可提供第二刷毛载体54的其它左右摇摆运动。例如，第二刷毛载体54可围绕销轴或铰链53摇摆或绕枢轴转动。可在第二刷毛载体54上的其它位置例如在任一末端处或在中间提供销轴或铰链，以提供在左右摇摆的方向上的不同种类运动。
转轴42通过第二刷毛载体54的伸出部60。伸出部60具有其中安放一部分转轴42的孔62。伸出部60被安放在在左右摇摆的方向上导引第二刷毛载体54的头部26的狭槽64中。转轴42的末端66可操作地与第一刷毛载体52的狭槽64(图6和7)接合以按绕轴线56的摆动运动移动第一刷毛载体52。
要注意的是，可将本文所述的任何方法和/或产品的任何特征、方面或细节或是完全地或是部分地与本文所述的一种或多种其它方法或产品的任何其它特征、方面或细节相组合。尽管已用具体实施方案来说明和描述了本发明，但对于本领域的技术人员显而易见的是，在不背离本发明的精神和保护范围的情况下可作出许多其它的变化和修改。因此，有意识地在附加的权利要求书中包括属于本发明范围内的所有这些变化和修改。
所有以上引用文献均引入本文以供参考，任何文献的引用不可解释为是对其作为本发明的现有技术的认可。
