如图1-图2所示，根据本发明的实施例，提供了一种充电底座，包括：壳体1，壳体1的上端设有放置槽2；通孔3，通孔3设于壳体1上并贯穿壳体1，通孔3与放置槽2的下端相连通；充电发射线圈5，充电发射线圈5设于壳体1内，充电发射线圈5能够为放置在放置槽2上的设备充电。放置槽2在使用时用于放置电动牙刷，电动牙刷内部具有充电接收线圈。在充电时将电动牙刷放置在放置槽2内，当电动牙刷的底端与放置槽2相接触后，壳体1即能对电动牙刷提供支撑，电动牙刷内的充电接收线圈能够与壳体1内的充电发射线圈5配合使用，从而使充电底座能够为电动牙刷充电；此时充电底座不仅能够为电动牙刷提供存放位置还能够在存放时对其充电。此外，由于电动牙刷在使用时和存放时均有可能沾上水渍，如果水渍长期不处理的话，容易出现污垢或霉斑。而本发明通过在壳体1上设置通孔3，通孔3能够排掉电动牙刷上的积水，使电动牙刷的表面保持干燥和通风，减少了污垢或霉斑的产生。
进一步地，壳体1上设有供电口6，供电口6与充电发射线圈5连接，外部电源能够通过供电口6为充电发射线圈5供电。
进一步地，还包括电路板7，电路板7设于壳体1内，电路板7与供电口和充电发射线圈5连接，电路板7能够对供电口和充电发射线圈5进行控制，从而提高充电底座在运行时的稳定性。
进一步地，壳体1的下端设有空槽4，空槽4与通孔3相连通，设置空 槽4能够增大壳体1下端的空间，并形成通风孔，从而加强通孔3的通风、干燥效果。
进一步地，从放置槽2的上端至放置槽2的下端，放置槽2的横截面面积逐渐减小，放置槽2的上端面积与放置槽2的下端面积的比为1:2-2:3，放置槽2的形状呈碗形能够使放置槽2的承载效果更好。
进一步地，壳体1包括支撑体101和环形缓冲体102，环形缓冲体102套设于支撑体101上；通孔3位于支撑体101上，供电口6位于环形缓冲体102中，电路板7位于充电底座中；环形缓冲体102的外表面上且与供电口6位置相对应处设有塞孔，塞孔上设有软胶塞8，软胶塞8通常位于环形缓冲体在厚度方向上的中部，供电口6与软胶塞的高度相同，电路板7通常位于充电发射线圈5和供电口6之间，环形缓冲体102为实心材料，能够增加充电底座的整体重量，从而使充电底座更加稳定，充电底座通过环形缓冲体102和支撑体101组装而成，分体式的生产降低了充电底座的生产难度，并且环形缓冲体102为软性材质，不会因磕碰造成损坏，能够使充电底座更加耐用。
进一步地，通孔3的中心线与放置槽2的中心线位于同一条直线，通孔3的中心线与放置槽2的中心线位于同一条直线，本发明采用下沉式设计，能够使得设备表面的水分在重力作用下向中心汇集，从而在中心的通孔可以保证水分的及时排除，提升通风干燥效果，能够使通孔3位于电动牙刷的正中心，从而提升通孔3的通风干燥效果。
进一步地，充电发射线圈5绕壳体1的轴线缠绕，一般情况下充电发射线圈整体呈环形或者类似环形，并与充电底座平行，这种缠绕方式能够最大程度的降低充电发射线圈5占用的垂直空间。
进一步地，从空槽4的上端至空槽4的下端，空槽4的横截面面积逐渐增大，通孔3的中心线与空槽4的中心线位于同一条直线，通孔3的中心线与空槽4的中心线位于同一条直线能够使空槽4的通气更加均匀，从而提升充电底座的通风效果。
进一步地，环形缓冲体102上设有环形凸起，支撑体101上设有环形凹槽，当环形缓冲体102套设于支撑体101上时，环形凸起位于环形凹槽内，环形凸起通过“嵌入”至环形凹槽的方式，使环形缓冲体102与支撑体101连接，通过环形凸起和环形凹槽能够增强环形缓冲体102与支撑体101的连 接强度。
本发明还公开了一种显示屏，如图3-图4所示，包括：显示屏本体10；透镜9，透镜9具有一个凹面和一个凸面，凹面位于靠近显示屏本体10的一侧；其中，从透镜9的边缘至透镜9的中心，透镜9的厚度逐渐增大，透镜9整体呈远离显示屏的方向凸出，显示屏所呈现的图像经过透镜9传播后得到了放大，并且扩大了显示屏可被观测到的视角，从而增大了观看显示屏的角度范围，使用者在非正面观看时(一定范围内)，也能够完整的观看到显示屏上的内容，本发明可以设置在牙刷11上，可在本发明的显示屏上显示刷牙引导内容，从而起到引导儿童刷牙的作用。
进一步地，凹面和凸面均为椭圆抛物面，凹面和凸面均为椭圆抛物面能够使透镜9上下对称、左右对称，使用户从各个方向观看显示屏时，观测效果保持一致。
进一步地，凹面的中心点、凸面的中心点和显示屏的中心点在同一条直线上，通过这种方式能够使透镜9与显示屏“对齐”，从而优化显示屏的显示效果。
进一步地，透镜9的边缘厚度与透镜9的中心的厚度的比为1:4-1:6。
进一步地，凹面的中心点与显示屏本体10之间的距离为D1，凸面的中心点与显示屏之间的距离为D2，D1的长度为D2的长度的0.125-0.67倍。
进一步地，凹面的边缘所在的平面与显示屏本体10平行，通过这种设计能够便于透镜9的定位，在安装时便于确定透镜9的安装位置。
进一步地，凹面的边缘所在的平面与显示屏本体10之间的距离不大于0.5cm。
进一步地，还包括固定面板12，显示屏本体10设于固定面板12上，固定面板12上设有卡槽，透镜9的边缘设置有凸起13，凸起13与卡槽卡接从而将透镜9固定在固定面板12上，通过凸起13能够便于将透镜9固定在固定面板12上，从而方便显示屏的安装。
本发明还提供了一种电动牙刷，该电动牙刷包括上述的充电底座和上述的显示屏。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：利用本发明实施例所提出的充电底座对电动牙刷充电时，能够为其提供支撑， 在通孔的作用下能够加快电动牙刷表面的水渍风干速度，提高牙刷充电时的便利性，本发明用过透镜增强了显示屏的显示效果，增大了显示屏的可视角度，提升了用户的使用体验。
以上所述仅为本发明的优选实施例，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
