最后可将本充电底盖组件装配于下文所述的机壳2内，且第三密封构件10恰好设置于第一封盖组件5和机壳2之间，防止向机壳2的内部漏水，保证机壳2内的充电组件4以及下文所述的机芯组件3的安全性以及可靠性。
当需要给电动牙刷充电时，仅需要将第二封盖组件6拆卸下来，将充电组件4通过充电器连接于外部的电源进行充电即可，充电完成后，再将第二封盖组件6安装回原位。
充电组件4的下方由第二封盖组件6以及第二密封构件9防护，使得下方不易漏水，起到一级防漏水的作用，充电组件4与第一封盖组件5之间设置有第一密封构件8，起到二级防漏水的作用，避免了向机芯组件3漏水，充电组件4的上方有防护罩7，起到三级防漏水的作用，避免了向机芯组件3漏水，同时也能避免反向漏水即从机芯组件3一侧朝向充电组件4漏水。可见，本充电底盖组件形成了一个全面密封的结构，防水效果更好。
其中，可选地，第一密封构件8、第二密封构件9以及第三密封构件10的结构可根据实际需要设置，例如第一密封构件8、第二密封构件9以及第三密封构件10可以为密封圈。

在该实施例中，优选地，如图3和图4所示，充电组件4包括基座41、充电线路板42以及导电构件43；其中，基座41设置于防护罩7内；防护罩7的内侧壁形成有朝向第一封盖组件5延伸的压设部71，且沿着第二封盖组件6的高度方向，压设部71压设于基座41，将基座41牢固地压设于第一封盖组件5，使得彼此之间接触得更紧密，不易漏水；
充电线路板42设置于基座41，并且充电线路板42连接于导电构件43；防护罩7形成有贯穿过口，导电构件43的一端穿过贯穿过口，且位于贯穿过口的外部，使得机芯组件3、充电组件4以及第一封盖组件5实现了稳定的装配关系，不易松散变形，接触得更紧密，进一步起到防漏的作用；
基座41还形成有充电接口44，充电接口44与充电线路板42电连接，通过充电接口44为电动牙刷供电；
基座41的朝向第一封盖组件5的一端形成有朝向第一封盖组件5的一侧开口的安装用槽411，第一密封构件8设置于第一安装槽511与安装用槽411之间，安装用槽411的槽壁能够压设住第一密封构件8，在保证安装结构的稳定性的同时加强密封效果。其中，可选地，此安装用槽411呈环形，且沿着高度方向的截面呈L形槽。

其中，第一安装槽511贯穿于本体51的一端，第二安装槽贯穿于本体51的相对的另一端；
基座41设置于第一安装槽511，装配更稳定；基座41与第一安装槽511的侧壁之间设置有第一密封构件8，实现密封；
第二封盖组件6包括基体61，基体61设置于第二安装槽，装配更稳定；基体61与第二安装槽的侧壁之间设置有第二密封构件9，实现密封；
