为了方便描述，定义空间上相互垂直的三个坐标轴分别为X轴、Y轴和Z轴，同时，沿X轴的方向为纵向，沿Y轴的方向为横向，沿Z轴方向为竖向；其中X轴与Y轴为同一水平面相互垂直的两个坐标轴，Z轴为竖直方向的坐标轴；X轴、Y轴和Z轴位于空间相互垂直有三个平面分别为XY面、YZ面和XZ面，其中，XY面为水平面，XZ面和YZ面均为竖直面，且XZ面与YZ面垂直。空间中三轴为X轴、Y轴和Z轴，沿空间上三轴移动指沿空间上相互垂直的三轴移动，特指在空间上沿X轴、Y轴和Z轴移动；而平面移动，则为在XY面移动。
请参阅图1至图3，现对本申请实施例提供的摆动牙刷进行说明。该摆动牙刷包括刷头1、刷柄2、安装于刷柄2上的摆动座3和连接刷头1与摆动座3的摆动杆4。。摆动座3包括沿第一方向(即图2中的X轴方向，下同)铰接于刷柄2上的第一铰接座31、沿第二方向(即图2中的Y轴方向，下同)铰接于刷柄2上的第二铰接座32和沿第二方向安装于第一铰接座31上的固定轴33。此处，第一铰接座31沿第一方向铰接于刷柄2上，是指第一铰接座31沿第一方向作为转动轴线，可绕第一方向在刷柄2上转动。同理，第二铰接座32沿第二方向作为转动轴线，可绕第二方向在刷柄2上转动。其中，第一方向垂直于第二方向。第二铰接座32位于第一铰接座31的上方，摆动杆4远离刷头1的一端穿过第二铰接座32并套设于固定轴33上。其中，摆动杆4可与Z轴形成一定角度，可绕Z轴实现360°旋转。
此结构，本申请通过将摆动座3设置为沿第一方向铰接于刷柄2上的第一铰接座31和沿第二方向铰接于刷柄2上的第二铰接座32。当刷头1受外力作用时，摆动杆4可带动第一铰接座31沿第一方向实现在刷柄2上的摆动；或者，摆动杆4在固定轴33上沿第二方向摆动，进而可带动第二铰接座32沿第二方向 实现在刷柄2上的摆动。因此，通过第一铰接座31和第二铰接座32的摆动，刷头1可在不同方向外力作用下实现多角度摆动，进而提高刷牙的舒适感。
在一个实施例中，请参阅图6，作为本申请实施例提供的摆动牙刷的一种具体实施方式，第二铰接座32上开设有供摆动杆4穿过的腰型孔320，腰型孔320的长轴方向沿第二方向设置。此结构，当摆动座3绕第一方向摆动时，腰型孔320可为摆动座3在第二方向上实现避让，从而实现刷头1绕第一方向摆动的可靠性。
在一个实施例中，请参阅图5、图7和图8，作为本申请实施例提供的摆动牙刷的一种具体实施方式，第一铰接座31的两端分别安装有第一轴颈311，各第一轴颈311的中轴线沿第一方向设置；刷柄2包括柄本体21和安装于柄本体21上的罩体22，柄本体21上对应于各第一轴颈311的位置处开设有第一凹槽211，罩体22上对应开设有与相应第一凹槽211配合夹持相应第一轴颈311的第二凹槽221。此结构，通过各第一凹槽211与相应第二凹槽221配合将相应第一轴颈311夹持，从而可提高第一铰接座31与刷柄2的连接稳固性，也可提高第一铰接座31摆动的可靠性。
在一个实施例中，请参阅图7，各第一凹槽211和各第二凹槽221均可为半圆形槽，从而可与呈圆柱体构型的第一轴颈311配合。在一些实施例中，刷柄2的内侧壁上可分别开设有供第一轴颈311伸入的盲孔，也可实现第一铰接座31在刷柄2上的摆动。在另一些实施例中，刷柄2上沿第一方向可安装有安装轴，第一铰接座31可套设安装于该安装轴上，也可实现第一铰接座31的摆动。当然，在其它实施例中，第一铰接座31与刷柄2的连接结构也可以根据实际需要进行调节，在此不作唯一限定。
在一个实施例中，请参阅图6至图8，作为本申请实施例提供的摆动牙刷的一种具体实施方式，第二铰接座32的两端分别安装有第二轴颈321，各第二轴颈321的中轴线沿第二方向设置；柄本体21上对应于各第二轴颈321的位置处开设有第三凹槽212，罩体22上对应开设有与相应第三凹槽212配合夹持相应第二轴颈321的第四凹槽222。此结构，通过各第三凹槽212与相应第四凹槽222配合将相应第二轴颈321夹持，从而可提高第二铰接座32与刷柄2的连接稳固性，也可提高第二铰接座32摆动的可靠性。
在一个实施例中，请参阅图7，各第三凹槽212和各第四凹槽222均可为半圆形槽，从而可与呈圆柱体构型的第二轴颈321配合。在一些实施例中，刷 柄2的内侧壁上可分别开设有供第二轴颈321伸入的盲孔，也可实现第二铰接座32在刷柄2上的摆动。在另一些实施例中，刷柄2上沿第二方向可安装有安装轴，第二铰接座32可套设安装于该安装轴上，也可实现第二铰接座32的摆动。当然，在其它实施例中，第二铰接座32与刷柄2的连接结构可以根据实际需要进行调节，在此不作唯一限定。
在一个实施例中，请参阅图2和图8，作为本申请实施例提供的摆动牙刷的一种具体实施方式，罩体22上开设有供摆动杆4穿过的通孔220，摆动杆4的外周面与通孔220的内周面间隔设置。此结构，通过通孔220的内侧壁可将摆动杆4抵挡，从而可限制摆动杆4的摆动角度。其中，摆动杆4的摆动角度可以根据摆动杆4的外周面与通孔220的内周面之间的间距进行调节。当该间距较大时，摆动杆4及刷头1的摆动角度也越大；反之，该间距较小时，摆动杆4级刷头1的摆动角度就越小。
在一个实施例中，请参阅图2至图4，作为本申请实施例提供的摆动牙刷的一种具体实施方式，摆动牙刷还包括用于弹性抵推摆动杆4至初始位置状态的弹性抵推单元5，弹性抵推单元5的一端与刷柄2抵接，弹性抵推单元5的另一端与摆动座3抵接。此结构，当刷头1受外力作用时，刷头1带动摆动杆4及摆动座3实现摆动，此时，弹性抵推单元5受力变形。当作用于刷头1的外力取消时，弹性抵推单元5在回弹力的作用下，可抵推摆动座3及摆动杆4至初始位置状态，便于后续重复作业。其中，摆动座3和摆动杆4的初始位置状态是指刷头1未受外力作用时的位置状态。
在一个实施例中，请参阅图3、图4和图9，作为本申请实施例提供的摆动牙刷的一种具体实施方式，弹性抵推单元5包括安装于固定轴33上的固定座51、与固定座51抵接的抵顶座52和用于弹性抵推抵顶座52的弹性件53，弹性件53的一端与刷柄2抵接，具体是与柄本体21抵接，弹性件53的另一端与抵顶座52抵接；抵顶座52远离刷柄2的侧面为第一平面521，固定座51面向抵顶座52的侧面为与第一平面521抵接的第二平面511。此结构，当摆动杆4通过摆动座3摆动时，可一并带动固定座51摆动，固定座51上的第一平面521与第二平面511呈一定角度分离，此时，固定座51抵推抵顶座52沿Z轴方向下降，弹性件53压缩。当作用于刷头1的外力取消时，弹性件53在回弹力的作用下沿Z轴回弹，并给予抵顶座52上升的回弹力，抵顶座52在上升的过程抵推固定座51， 直至第一平面521与第二平面511贴合，此时，摆动座3及摆动杆4摆动至初始位置状态。
在一些实施例中，弹性抵推单元5也可为一端与柄本体21连接、另一端与摆动座3连接的弹簧或弹片。当然，在其它实施例中，弹性抵推单元5的结构也可以根据实际需要进行调节，在此不作唯一限定。
在一些实施例中，固定座51与摆动杆4可为一体成型，从而便于加工制作。当然，在其它实施例中，固定座51也可与摆动杆4为分体设置，如螺丝锁紧连接，粘接等，在此不作唯一限定。
在一个实施例中，请参阅图3和图7，作为本申请实施例提供的摆动牙刷的一种具体实施方式，刷柄2上安装有导向柱213，弹性件53套设于导向柱213上。具体地，导向柱213可安装于柄本体21上。其中，弹性件53可为弹簧。此结构，通过导向柱213可实现对弹性件53的定位，避免弹性件53因位置发生偏移而失效。抵顶座52远离固定座51的一端伸入导向柱213中，从而可实现快速定位装配，效率高。
在一个实施例中，请参阅图4和图9，作为本申请实施例提供的摆动牙刷的一种具体实施方式，固定座51上开设有供摆动杆4远离刷头1的一端伸入的容置槽512。此结构，通过容置槽512可实现摆动杆4与固定座51的快速定位安装，效率高。
在一个实施例中，请参阅图3和图4，作为本申请实施例提供的摆动牙刷的一种具体实施方式，刷头1上开设有供摆动杆4远离刷柄2的一端伸入的定位槽11；摆动杆4上开设有卡槽41，定位槽11的内侧壁上安装有与卡槽41配合卡合的卡钩12。此结构，通过定位槽11可实现摆动杆4与刷头1的快速定位连接；通过卡钩12与卡槽41的配合，可提高摆动杆4与刷头1之间的连接稳固性。
以上所述仅为本申请的可选实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
