的刷牙方式， 釆用竖向刷牙相对于横向刷牙不仅清洁更加彻底， 且采用上下 竖向的方式与牙齿表面的紋理同向， 不会在牙齿的表面形成横紋, 且不会伤 及牙龈。 故应用本实施例 电动牙刷不仅能够达到强力清洁的效果， 且能够 最大程度的保护空腔的健康。 '
特别^， 本 施例 的电动牙刷特别适合需要纠正刷牙习惯的人群、 ^及正在学习刷牙的小孩， 应用本电动牙刷有利于帮助人们纠正不正确的刷 牙习惯， 养成正确的刷牙习惯。 附图说明
此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部 分， 并不构成对本发明的不当限定， 在附图中:

下面将结合附图以及具体实施例来详细说明本发明, 在此本发明的示意 性实施例以及说明用来解释本发明， 但并不作为对本发明的限定。
实旅例 1 : ：
图 1为本实施例 1提供的一种电动矛刷的整体机构示意图 参见图: 1所 示,本电动牙刷包括用于供人们握拿的刷柄 105、 以及设置在刷柄 105—端部 的用于清洁口腔的刷头 104，在刷头 104的一端设置有一沿轴向伸出的中心轴 1041 , 该中心轴 1041插在刷柄 105的空腔内。
本电动牙刷的动力部分设置在刷柄 105 内部， 其包括顺次连接的微型电

下摆动， 在使用时 用上下的方式竖向刷 。 相对于现有技术中的电动牙刷， 应用本实施例的电动牙刷更加符合枓学 的刷牙方式, 采用竖向刷牙相对于横向刷牙不仅清洁更加彻底， 且采用上下 竖向的方式与牙齿表面的纹理同向， 不会在牙齿的表面形 横纹， 且不会伤 及牙龈。 故应用本实施例的电动牙刷不仅能够达到强力清洁的效果, 且能够 最大程度的保护空腔的健康。
特别地， 本实施例提供的电动牙刷特别适合需要纠正刷牙习惯的人群、 以及正在学习刷牙的小孩， 应用^电动牙刷有利于帮助人们纠正不正确的刷 牙习惯， 养成 确的刷牙习惯。
在本实施例中可以将偏心槽 1031的长度设为： 偏心、轴 1022的最远边缘 到传动轴 1011的轴心的距离的两倍, 即偏心槽 1031的长度与偏心轴 1022作 的圓周运动的运动轨迹的外直径相等。 这样有利于使得本电动牙刷的电动更 加稳定。 此时， 偏心轴 1022与偏心槽 1031的相对运动轨迹可以参 图 2所 示。 . .. · · '· .' · .
参见图 2所示， 当偏心轴 1022从位置 201运动到位置 202时, 带动偏心 槽 1031发生偏转, 从而带动整个第二偏心轮, 103 ^生偏转; 当偏心轴 1022 从位置 202运动到位置 203时， 偏心轴 1022从偏心槽 1031 0 第一端部滑动 到与之相对的第二端部， 第二偏心轮 103的位置不动; 当偏心轴 1022从位置 203运动到位置 204时，偏心轴 1022从偏 槽 1031的第一端部清动到与 ^相 对的第二端部， 第二偏心轮 103的 置不动; 当偏心轴 102 从位置 204运动 到位置 201时， 又带动偏 槽 1031发生偏转， 从^带动整个第 偏 轮 103 发生偏转。: . 由图 2可见， 当偏心槽 1031的长度等于偏心轴 1022的运动轨迹的 径 时, 在电机 101传动轴 1011旋转的过程中， 第二偏心轮 103绕位更 203为摆 动支点, 以位置 201与位置 204形成的直线为中心线作上下摆动，：从而带动 固定在第二偏心轮 103的第二端面上的刷头 104中心轴 1041作上下摆动，进 而带动刷头 104作上下摆动。
另外， 作为本实施例的一种优选方案， 可以但不限于将偏心槽 1031的位 置设置成:使偏心槽 1031的中心、 离第二偏心轮 103的轴心，即令偏心槽 1031 偏心设计。' : . '
作为本实施^的一种优选方案, 本实施例电动牙刷的各关键 件的连接 关系可以但不限于如图 3、 4所示。
参见图 3、 4， 在第一偏心轮 102的一端面中心设置有轴孔, 微电机 101 的传动轴 1011固定在该轴孔内， 在第一偏 轮 102的另一端面上的非中心位 置设置有一偏心轴 1022，该偏心轴 1022限俥于第二偏心轮 103的偏心槽 1031 上， 该偏心槽 1031的中心位置偏离第二偏心槽 1031的中心位置， 该偏心槽 1031的长皮为偏心轴 1022的最逸边緣到第一偏心轮 102的中心的距^的两 倍。 在第二偏心轴 1022的另一端面上设置有一周固定机构， 该轴固定机构与 位于^柄 105的 φ心^刷头 104中心轴 1041固定连接。
以上对本发 实施例所提供的^术方案进行了详细介绍， 本文中应用了 具体个例对本发明实施例的原理以及实施方式进行了阐述， 以上实施^的说 明只适用于帮助理解本发明实施例的原理； 同时.， 对于本领域的一般技术人 员， 依据本发明实施例， 在真体实 方式以及应用范围上均会有改变之处， 综上所述， 本说明书内容不应理解为对本发明^限制。
