Abstract

电动牙刷包括一个刷柄和一个刷头，其特征在于其刷头有为薄片状形式的橡胶清洗元件和刷毛束。特别是橡胶清洗元件的薄片状在平行于刷头底部的横切面上为直线或弧形，并且刷头是可替换的。

Description

电动牙刷
技术领域
本发明涉及一个包括一个刷柄和一个刷头的电动牙刷，其特征在于刷头有橡胶清洗元件。
背景技术
电动牙刷在技术领域里众所周知，其典型地包括一个包容在刷柄里的电动元件和一个刷头，刷头通常是可替换的。
大多数电动牙刷通过快速地移动刷头(以下称为摆动牙刷)来起到清洗作用，但是有些牙刷只不过是振动(以下称为振动牙刷)。
市场上有许多摆动牙刷，一些有特殊的摆动图案，例如，有纵向摆动元件，或者它们也可以有多个刷头，如这样一种菲利浦公司销售的商标为“Plaque Remover”的牙刷。此牙刷包括一个旋转刷头和一个在刷柄末端的横向摆动的刷毛组。
振动牙刷的例子是由J&J公司销售的商标为“Powerbrush”的牙刷。
现有技术的有橡胶刷毛的手动刷是众所周知的，其可以提供擦亮、清洗或牙龈处理的效用。例如，WO 98/22000(Asher)公开了一种牙刷包括至少一个由许多刷毛包围的清除牙斑的元件。
在我们共同未决的申请GB9912923.1中我们描述了一种牙刷，此牙刷包括一个用于包容电动元件的外壳和一个刷头，此刷头是柔性的。
我们发现，包含橡胶清洗元件的刷头如果应用到电动牙刷上，其提供的效用会大大增强。
发明内容
本发明的一个目的是提供一种廉价的电动牙刷，本牙刷可提供一种增强的清洗效用。
我们发现，当牙刷头包括橡胶清洗元件时，电动牙刷能在现有技术上提供改进。
因此，本发明提供一种电动牙刷，包括一个刷柄和一个刷头，其特征在于刷头包含为薄片状形式的橡胶清洗元件和刷毛束。
应用橡胶清洗元件意味着清洗元件如刷毛是用橡胶材料制成的，即具有柔性和弹性特征的一种橡胶材料。
在一优选的实施例中，橡胶清洗元件是手指的形状，通常比传统的尼龙刷毛要粗。
在一特定的优选实施例中，橡胶清洗元件是片状或者薄片形状。这种片状或薄片物在平行于刷头底部的横切面上可以成直线或弧形。
根据橡胶元件的尺寸，可以设想许多橡胶元件可以放置在牙刷上，而且可以与任何刷毛束组合。
橡胶清洗元件是由橡胶材料制成的放大的刷毛。应用橡胶意味着这种材料具有一些弹性特征。如果电动牙刷以很高频率振动，可以预测出不需要高弹性的材料，肖氏A硬度小于100的材料适合在本发明中应用。
在一优选的实施例中，橡胶材料的肖氏A硬度小于100，更优选的是小于80，最好是小于55，而且橡胶材料最小的肖氏A硬度优选为15，更优选为25。
特别适合的橡胶材料包括例如那些在WO 97/20484中描写的弹性材料，其内容合并作为参考。
根据本发明还期望牙刷头是可替换的。
橡胶清洗元件还可以对牙齿表面提供擦亮的效用。
也有可能橡胶清洗元件附加包含类似硅的磨擦材料，以增强清洗和擦亮的效用。
在另一方面，本发明提供了改善感觉的好处。根据本发明的牙刷由于橡胶材料的应用改善了口腔中的感觉。当刷头的非刷毛支承表面有效地由橡胶材料覆盖并接触口腔内部时，特别有这样的感觉。这种感觉的好处被看做是消费者一种重要的肯定。
根据本发明的牙刷头可以是振动刷头或者摆动刷头。例如，橡胶清洗元件可以只靠振动来起到清洗作用，或者它也可以固定在旋转刷头上。
本发明将参照以下附图进行描述。
附图说明
图1是根据本发明的牙刷的正视图。
图2是图1所示牙刷的平面图。
图3是另一刷头的平面图。
具体实施方式
图1是根据本发明的牙刷的正视图。图示牙刷(1)包括刷柄(2)和刷头(3)。刷头(3)包含刷毛支承部(4)和颈部(5)。刷毛支承部(4)包括橡胶清洗元件(6)和传统的尼龙刷毛束(7)。
典型地，刷柄(2)将包含一个电动元件，此电动元件至少可以振动或摆动刷头。
图2是图1所示牙刷的平面图，显示橡胶清洗部件和传统刷束的布局。
图3是刷头的平面图，此刷头被设计为可绕中心点(9)旋转。
其中示出手指形状(10)和薄片状(8)的橡胶清洗元件及传统的刷毛(7)。
