Abstract

电动牙刷,它的转动轴(12)具有配合到牙刷刷毛架(13)中槽(22)内的远端(20)。架(13)安装成可于牙刷头(11)支承的柱(18)上转动。当轴(12)转动时,远端(20)作划圆运动并同槽(22)作驱动结合以促使架(13)振动。

Description

牙刷
本发明涉及牙刷。
本发明特别涉及这样的电动牙刷，其牙刷刷毛设置成能相对牙刷柄运动。
有许多这类牙刷的例子，包括美国专利US 2215031于1939年公开的旋转驱动的牙刷刷毛。类似的旋转驱动的装置也公开于美国专利US4845795中。美国专利US 4156620说明了如何将马达驱动的转动转变为往复线性运动来驱动牙刷刷毛作顺时针走向和作反时针走向的转动。美国专利US 3577559公开了一种牙刷，其中的牙刷头能相对于牙刷把运动，而使得安装于牙刷头上的所有刷毛能一起相对于牙刷把作侧向、后向与前向的运动。
本发明涉及使牙刷刷毛相对于牙刷头运动以提高牙刷在使用时的清洁作用，本发明同时有这样的目的，即提供能以简单有效方式实现上述相对运动的牙刷。
根据本发明所提供的电动牙刷，它具有：牙刷把、牙刷头和可旋转的轴，此轴的纵向中心轴线从牙刷把延伸至牙刷头；还具有可枢轴旋转地安装于牙刷头上并可为上述轴的远端作驱动结合的牙刷刷毛架，此远端相对于上述中心轴线偏心设置而使刷毛架能在该轴转动时绕其支轴振动。
上述轴最好整体形成而使其远端弯离中心轴线。
刷毛架可有一槽，轴的远端就安装在该槽中。
刷毛架可安装成绕一轴线转动。
此刷毛架可布置成在10°至50°的角度内振动；这一角度最好约为30°。
下面参考附图以举例方式说明本发明的牙刷，附图中：
图1是本发明的牙刷的剖面底视图；
图2是此牙刷一部分的横剖侧视图；
图3是图2的剖面底视图；
图4是图2的相对侧视图；
图5、6、与7是不同牙刷和不同尺度下的与图2、3与4分别相同的图。
参看附图，图1中的牙刷包括牙刷把10、牙刷头11、从牙刷把延伸到牙刷头11的转动轴12以及牙刷刷毛架13。上述把中设置有小室以盛纳马达14与两节电池15与16。设有联轴器17以夹住轴12的一端并能让轴抽出得以如后所述进行清洗或更换。
从图2中可以较清楚地看到，牙刷头11支承着一个柱18，后者为刷毛架13提供了转动的枢轴。图2中所示的刷毛19仅仅是供说明所用。轴12有整体形成的远端20，后者偏离轴12的中心轴线21设置。
远端20配合到刷毛架13一侧中形成的槽22内(参看图3)。可以看到，远端20指向轴线21与柱18的中心轴线的交点。当轴21为马达14带动转动时，远端20绕轴12作划圆运动并驱动地与槽22结合促使刷毛架13振动。于是，架13便绕柱18的中心轴线作正反转动。上述振动包括在牙刷头11与刷毛19之间的相对运动，这通常有利于高效地清洁牙齿。槽22的宽度最好与远端20的直径大致相同，以使留出的间隙最小；这样可在使用中使噪声保持到最小。
马达14最好以约6000rpm运转。在有需要时，此马达也可依其它转速运行，或可以设置成可为用户选择的两或多个速度运行。图1所示的牙刷中，刷毛架13是通过30°的角度振动或转动。图2中这一角度是35°，而图5中这一角度是15°。于是可以知道，通过配合不同的轴12能够选择转动角度，而同一刷毛架则可用于所有角度。
各个刷毛架13都可设置多于一个槽22以便取得较好的平衡，或便于在使用中有一个槽损坏或刷毛磨损得不均匀时能够使用不同的槽。换言之，架13可以按两或多个转动位置调整。架13最好安装成易从牙刷头11上卸下，例如借弹力夹定于柱18上。这样的可卸下方式便于更好地清洗和存储于卫生容器中，同时能使轴12在有需要时快速地撤出和更换。
上述的轴12最好整体成形为图中所示形式。但也可使远端20独立地成形或设定于此轴的一个直端部上。这样一个独立部分可以是所具中心轴线与轴12的轴线21重合的毛刷和一偏心的驱动柱。此驱动柱这时便占有远端20的位置同时起到此远端的作用。这样，此驱动柱与槽22便在轴与架13之间形成驱动结合，使得驱动柱本身可以视作为轴12的远端。
在本发明的某些实施形式中，还能够但并不常常是方便地将架13可枢轴旋转地铰接到例如与轴相对的一侧上。这时安装于铰支轴较近处的刷毛事实上就不能同与轴12邻接一侧上的刷毛那样运动，但它们却仍能显著地振动。
应知刷毛架13不论是由枢轴支承转动或取铰接形式，都可以不是圆形的。但是，圆形的架13通常是较理想的，因为它的转动位置如前所述可以根据需要变更。
