Description

竖刷式电动牙刷
本申请要求了申请日为2014年09月04日，申请号为201410446425.5发明名称为“竖刷式电动牙刷”的中国专利申请的优先权。
技术领域
本发明涉及到动力驱动的清洁装置，特别是电动牙刷。
背景技术
市场上牙刷主要手动操作，电动牙刷与普通牙刷相比，更为科学有效。电动牙刷可以更彻底清洁牙齿、清除牙菌斑、减少牙龈炎和牙龈出血。目前市场出售的是主要是牙刷头旋转类的电动牙刷，声波驱动牙刷，缺少牙医推荐的竖刷牙方式的电动牙刷。旋转类刷头的电动牙刷就是电动机驱动圆形刷头旋转，如高露洁专利CN 1438857 A专利方案。旋转刷头执行刷牙动作的产生牙齿表面清洁效果，旋转更多清洁牙齿表面对牙缝深度清洁程度不够。CN 1491623 A专利是齿轮驱动型，齿轮结构复杂。声波驱动牙刷通过振动口腔内的水、牙膏等液体产生大量微小气泡，在牙齿周围气泡瞬间爆裂产生高压冲击清洁达到清洁的目的。但是超声波刷头毛硬，长时间使用会对破坏牙釉质,口腔敏感人群使用不舒适。
发明内容
本发明主要解决牙刷头垂直于刷柄方向高频摆动的竖刷式电动牙刷，更接近于牙科医生推荐的科学刷牙方式。
本发明由可更换牙刷头和牙刷柄组成。牙刷头部分包含：刷头面板1、面板楔形触点2、面板平衡定位圆轴3、弹簧片4、牙刷头壳盖5、活动定位孔6。牙刷柄部分包含：电源7、电源开关8、电机9、驱动杆10、螺旋头11、防水胶垫12、牙刷柄保护壳体13、排水孔14。电机9带动驱动杆10高频转动，驱动杆前端螺旋头11高频碰撞刷头面板楔形触点2产生下压力，刷头面板上面板平衡定位圆轴3支撑牙刷壳盖5活动定位孔6向下转动，刷头面板1转动过程偏心受压弹簧片4，反作用力把刷头面板1恢复到初始位置。实现牙刷头垂直于刷柄方向反复高频摆动，实现竖刷牙齿。
竖刷式牙刷可让刷毛的往返方向与牙齿缝的方向一致，能有效清除牙齿表面和牙缝的污垢等，符合牙科医生推荐的科学刷牙方法。牙刷头与牙刷柄可拆卸更换。牙刷头简单结构不包含电路适合水洗。刷头面板可为钻石形状刷头，圆形状刷头，方形状刷头等不规则结构牙刷头。牙刷头结构适用于电机驱动以及声波电机驱动等驱动方式。

图2为刷头装配示意图
图3为刷头侧部透视图。
具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
如图1所示：牙刷柄13内含电源7和电机9。牙刷柄部分由电池向电机提供电力。电源开关8可接通或关闭电源，使电机旋转或停止。电机连接驱动杆，实现驱动杆旋转。驱动杆10头部为螺旋头11结构，驱动杆可置入牙刷头中空部分。电源接通时，电机9带动驱动杆转动，驱动杆前端螺旋头11转动过程高频反复接触刷头面板上的面板楔形触点2。驱动杆末端安装防水胶垫12，防水胶垫是防水结构部分。如图2所示：面板楔形触点2与刷头面板1为45°斜角结构。面板楔形触点2、平衡定位圆轴3、刷头面板1为一体结构。面板楔形触点顶部为倒三角形结构，扩大接触面积，并使刷头面板质量平衡。面板楔形触点2受到驱动杆前端螺旋头11撞击与平衡定位圆轴3产生作用力偏心转动。平衡定位圆轴为刷头面板质量中轴，是刷头面板两侧突出圆轴部分，牙刷头壳盖内部前端末端设置活动定位孔6，刷头面板能方便卡扣入牙刷盖，实现刷头面板垂直于刷柄方向自由转动。牙刷壳盖顶部设置排水孔14与防水胶垫12组合形成排水防水结构。刷头面板可为钻石形状刷头，圆形状刷头，方形状刷头等不规则面板结构。如图3所示：牙刷头壳盖内部设置固定弹簧片槽位，弹簧片4末端固定在刷头壳盖，弹簧片中部与牙刷盖是变形支撑结构。弹簧片4紧贴刷头面板1上面，提供变形恢复作用力。刷头面板1转动偏心受压弹簧片一端，弹簧片3把刷头面板1恢复到初始位置。牙刷头壳盖略大于刷头面板1，两者之间有缝隙不影响刷头面板垂直于刷柄方向摆动。牙刷头壳盖5内部前端末端有活动定位孔6，小孔略大于平衡定位圆轴3可扣入牙刷头壳盖活动定位孔6自由转动。驱动杆前端螺旋头11高频碰撞刷头面板楔形触点2，刷头面板平衡定位圆轴3转动，刷头面板1偏心受压弹簧片4，弹簧片4反作用力恢复刷 头面板1位置。实现刷头面板垂直于刷柄方向反复高频摆动。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
