在本发明实施例中，所述电动机21可为一个马达，所述电动机21可带有一个转子，其中，所述转子可与所述齿轮222表面的锯齿结构互相啮合，如此，当所述电动机21启动时，所述转子将发生高速旋转，并带动所述齿轮222转动。
需要说明的是，在本发明实施例中，所述刷柄20还包括防护套24，所述防护套24可为一个隔热防水套，其套设在所述限位件226上，且所述传动杆 23可在穿过所述限位件226后再次穿过所述防护套24。由于所述防护套24具有弹性，因而其可紧紧贴在所述传动杆23的表面及所述限位件226的表面，如此，可防止刷牙时从刷头10进来的水通过所述传功杆23渗透到所述电动机21内，避免了所述电动机21由于进水而损坏。

请一并参阅图1至图3，使用时，启动开关按钮，所述电动机21开始工作，所述电动机21的转子做高速转动，由于所齿轮222与所述转子啮合，因 而所述齿轮222也做同步转动。此时，由于所述连杆225位于所述齿轮222的偏心位置，因而，其设置于所述主体部221上的另一端将做圆周运动，该圆周的半径与所述连杆225相对所述齿轮222的偏心位置有关。由于所述连接臂223连接在所述连杆225上，因而在所述连杆225做圆周运动时，所述连接臂223将做来回的摆动，摆动的方向大致沿所述连接臂223的臂长的延伸方向，进而所述定位件224带动所述传动杆23整体也做相应的摆动。所述传动杆23将这个摆动的动作传递到位于所述壳体11内的一端，并通过来回摆动拨动所述刷毛12的拨动部，进而使得所述刷毛12也做来回的往返摆动，其中，摆动的方向为在刷牙时与牙齿的生长方向一致的方向。由于本发明实施例的传动组件22使用了分摆的结构设计，而这种结构设计可以获得增力的效果，因而可获得较佳的清洁效果。例如，在电动机为5400转负载的情况下，可获得每分钟7300次甚至更高转速，即所述刷毛12的摆动频率更大。
综上所述，本发明实施例提供的电动牙刷100，通过所述齿轮222、连接臂223及定位件224形成一个分摆的增力结构，再利用这个分摆结构驱动所述传动杆23，使得所述传动杆23快速拨动所述刷毛11的拨动部，进而使得所述刷毛11快速摆动，从而可以更有效的清洁牙齿，达到好的刷牙效果。
请一并参阅图4及图5，本发明第二实施例提供一种竖刷式电动牙刷3100，所述竖刷式电动牙刷3100包括刷头310及传动部320，其中，所述刷头310包括刷毛311、固定部312及拨动部313，所述刷毛311设置于所述固定部312的一侧，所述拨动部313设置于所述固定部312的另一侧，且所述拨动部312上开设有开孔314。所述传动部320包括电动机321、传动杆322及拨杆323， 所述传动杆322的一端固定在所述电动机321上，另一端固定所述拨杆323，且所述拨杆323的自由端正好位于所述开孔314的两壁之间。所述电动机321工作时通过所述传动杆322带动所述拨杆323转动，所述拨杆323的自由端在转动时来回碰撞所述开孔314的两壁，进而带动所述刷毛311沿碰撞的方向作来回直线运动。

在本发明实施例中，所述拨动部313大致呈空心圆柱筒状，所述开孔314开设于所述拨动部313的周壁，并贯穿所述周壁，从而所述开孔313相对的两侧各有一个侧壁，且所述拨杆323的自由端在伸入所述刷头310后，正好位于所述开孔314的两个侧壁之间。可以理解的是，在本发明实施例中，所述开孔313的大小可根据实际需要进行设计，其中，当所述开孔313较小时，可使得所述拨杆323的自由端与所述拨杆323的两壁产生更多的碰撞，从而增大了刷毛311振动的力矩及振动频率。应当理解的是，在本发明其他实施例中，所述开孔314也可不贯穿所述周壁，如所述开孔314可仅开设于所述拨动部313的上半部分、下半部分或开设于所述周壁的中间，这些方案均在本发明的保护范围之内，在此不再赘述。
请一并参阅图6，在本发明实施例中，所述竖刷式电动牙刷3100还包括固定外壳330，所述固定外壳330为所述传动部320提供外壳保护及支撑结构，其中，所述固定外壳330还具有一容置腔331，所述容置腔331可用于放置所述刷头310的拨动部313。具体为，在所述拨动部313的空心区域内，还设置 有固定杆315，在所述容置腔331内还设置有一个固定管332，所述刷头310的固定杆315可插入所述固定管332内，从而将所述刷头10安装在所述固定外壳330上，其中，所述固定管332的半径应略大于所述固定杆315的半径，以保证所述刷头310整体可自由转动。
在本发明实施例中，所述传动杆322的两端可分别通过传动轴套或相应的传动结构与所述电动机321及拨杆323实现机械连接，从而所述电动机321可通过所述传动杆322带动所述拨杆323旋转。例如，所述电动机321可设置有转轴，并通过将装置嵌套在所述传动杆322的一端，以实现所述电动机321与所述传动杆322的传动连接，同样的，在所述传动杆322的另一端，所述拨杆323也可套设或嵌套在所述传动杆322上。
需要说明的是，在本发明实施例中，所述传动部320还包括拨杆固定件324，所述拨杆固定件324可呈圆柱体状，其中，所述拨杆固定件324的一端固定于所述传动杆322上，所述拨杆323则固定于所述拨杆固定件324的另一端，从而通过所述拨杆固定件324将所述拨杆23固定于所述传动杆322上。
请一并参阅图7，在本发明实施例中，所述拨杆323可伸入到所述容置腔331内，其中，为了控制所述拨杆323伸入所述容置腔331内的长度，所述拨杆固定件324上可设置有卡口3241，而在所述容置腔331与所述拨杆固定件324的连接处设置有卡合件(图未示)，所述拨杆323及所述拨杆固定件324伸入到所述容置腔331内到预定的位置时，所述卡合件将卡在卡口3241上，从而所述拨杆固定件324不能继续伸入。其中，所述预定的位置是使所述拨杆323的自由端正好位于所述开孔314的两个侧壁之间的位置，从而所述拨杆323的自由端在转动时可碰撞到所述开孔314的两壁。
在本发明实施例中，所述拨杆323可为具有预定弧度的柔性杆，如所述拨杆323可由橡胶或塑料等材料制成，所述拨杆323的可通过注塑的方法固定在所述拨杆固定件324的圆心位置(或非圆心位置)，另一端(即自由端)位于所述开孔314的两壁之间，其中，在注塑时，应使所述拨杆323形成预定的弧度。所述电动机321转动时，通过所述传动杆322带动所述拨杆323做360度旋转，由于所述拨杆323具有弧度，在旋转过程中，所述拨杆323的自由端的轨迹为一个圆周，其圆周半径由弧度决定，且所述拨杆323的自由端将与所述开孔314的两壁发送接触并碰撞，在碰撞过程中，所述拨杆323发生形变，并驱使所述刷头310整体沿碰撞的方向移动，其中，移动的距离由所述拨杆323的弧度及所述开孔314的尺寸共同决定。由于所述拨杆323是360度旋转的，因而在所述拨杆23的整个旋转过程中，所述拨杆23的自由端将与所述开孔314的两壁交替发送碰撞，进而所述刷头310沿碰撞的方向上来回做直线运动，其中，碰撞的方向(或运动的方向)即是进行竖刷式刷牙时的刷牙方向。
在本发明的其他实施例中，所述拨杆323还可为柔性杆，如所述拨杆323可由橡胶或塑料等材料制成，所述拨杆323可通过注塑的方法固定在所述拨杆固定件324的非圆心位置(类似偏心轮的结构)，另一端(即自由端)位于所述开孔314的两个侧壁之间。所述电动机321转动时通过所述传动杆322带动所述拨杆323做360度旋转，由于所述拨杆323固定在所述拨杆固定件324的非圆心位置，因而其自由端的转动轨迹为一个圆周，该圆周的半径由该拨杆323与所述拨杆固定件324的圆心的距离决定。在旋转过程中，所述拨杆323的自由端将与所述开孔314的两个侧壁发送接触及碰撞，在碰撞过程中，所述拨杆323将驱使所述刷头310整体沿碰撞的方向移动，由于所述拨杆323是 360度旋转的，因而在旋转过程中，所述拨杆323的自由端将与所述开孔314的两个侧壁交替发送碰撞，进而所述刷头310在碰撞的方向上来回做直线运动，其中，碰撞的方向(或运动的方向)即是进行竖刷式刷牙时的刷牙方向。
需要说明的是，在本发明实施例中，在所述传动杆322与所述拨杆固定件324的连接处还设置有硅胶325，所述硅胶325可用于导热并将热量快速散发出，以防止在高速转动过程中在传动杆322与所述拨杆固定件324的连接处温度过高。
需要说明的是，在本发明实施例中，在所述传动杆322与所述电动机321的连接处还设置有防水件326，所述防水件326可为水封，其可防止刷牙时使用的水进入到所述电动机321内，而使所述电动机321损坏。
需要说明的是，在本发明实施例中，所述竖刷式电动牙刷3100还包括可充电电池340，所述可充电电池340设置于所述固定外壳330内，并与所述电动机321电连接，并向所述电动机321提供工作时所需的电能。
需要说明的是，在本发明实施例中，所述竖刷式电动牙刷3100还包括电源接口350，所述电源接口350设置于所述固定外壳330内，并与所述可充电电池340电连接，以通过外部电源对所述可充电电池340进行充电。
需要说明的是，在本发明实施例中，所述竖刷式电动牙刷3100还包括定位支架360，所述电动机321固定于所述定位支架360内。
综上所述，本发明实施例提供的竖刷式电动牙刷3100，通过所述电动机321、传动杆322及拨杆323组成的传动部320，保证了高效的机械传动，使得所述拨杆323可高速拨动及碰撞所述刷头310的拨动部313，从而所述刷毛311在直线方向上高速振动，并具有较大的振动力矩及振动频率，达到有效清 洁牙齿的目的，并可避免出现刷伤牙齦，造成牙齦出血，引起细菌感染、口腔发炎等，起到预防口腔疾病的发生，达到卫生、保健的作用，满足人们的使用要求。
以上所揭露的仅为本发明一些较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
