本申请实施例的目的在于提供一种电动牙刷，用于解决现有的电动牙刷头噪音较大、震动较大的问题。
在一个实施例中，一种电动牙刷头，可以包括刷头壳体、刷毛件以及配重件。沿所述刷头壳体的延伸方向，所述刷头壳体可以具有相对的刷毛端和连接端，所述连接端可以构造成与电动牙刷的刷柄的传动轴连接；所述刷头壳体内部可以开设有容置腔，所述容置腔开设的位置可以邻近所述刷毛端；所述刷毛件可以设置于所述刷毛端；所述配重件可拆卸设置于所述容置腔中，所述配重件位于所述容置腔中时，所述配重件可以邻近所述刷毛端。
如图1和图2所示，一实施例的电动牙刷头10，可以包括刷头壳体100、刷毛件200以及配重件300。沿所述刷头壳体100的延伸方向，所述刷头壳体100可以具有相对的刷毛端110和连接端120，所述连接端120可以用于与电动牙刷的刷柄的传动轴21连接。所述刷头壳体100内部可以开设有容置腔101，所述容置腔101开设的位置可以邻近所述刷毛端110。所述刷毛件200可以设置于所述刷毛端110；所述配重件300可拆卸设置于所述容置腔101中，所述配重件300位于所述容置腔101中时，所述配重件300可以邻近所述刷毛端110。在本实施例中，所述传动轴21带动所述刷头壳体100摆动。
上述的电动牙刷头10，由于在刷头壳体100内部开设的容置腔101中设置了配重件300，即给刷头壳体100的摆动配重，能有效降低与刷头壳体100连接的刷柄的震动以及保证噪音尽可能小， 而且由于配重件300邻近刷毛端110设置，即配重件300远离连接端120设置，因此避免影响传动轴21对刷头壳体100的带动作用，此外由于配重件300是可拆卸设置在容置腔101中的，因此便于更换不同的配重件300以适应不同的减震减噪需求。
为了便于在刷头壳体100的邻近所述刷毛端110的位置开设容置腔101、便于设置配重件300以及便于调整配重件300的位置，在一个实施例中，如图2所示，所述容置腔101可以为条形状腔体，所述容置腔101的延伸方向可以与所述刷头壳体100的延伸方向平行。由于容置腔101可以为条形的，因此当配重件300不长时可以设置在容置腔101中的不同位置，从而改变刷头壳体100的重心，进而适应不同电动牙刷的动力输出需求，而且可以选用不同长度的配重件300，即可以选用不同重量的配重件300，从而也能改变刷头壳体100的重心，进而适应不同电动牙刷的动力输出需求；此外，为了方便使用者将刷毛端110及刷毛件200伸入口中进行刷牙，刷头壳体100的邻近刷毛端110的部分需要制造得较细，因此容置腔101设置成条形状的，不仅便于在刷头壳体100较细的部分的内部开设容置腔101，而且可以选用同样为条形状的配重件300设置在容置腔101中相对应，且能保证配重件300的重量，从而保证配重效果。
为了便于连接端120与刷柄的传动轴21连接从而方便安装电动牙刷头10，在一个实施例中，如图2所示，所述连接端120的端面可以开设有安装口121，所述刷头壳体100的内部还可以开设有安装腔102，所述安装腔102可以与所述安装口121连通，所述安装腔102可以用于安装从所述安装口121活动穿设至所述安装腔102中的所述传动轴21，通过将传动轴21从安装口121伸入到安装腔102中，并将传动轴21设置在安装腔102中，使得刷头壳体100与传动轴21连接，从而使得电动牙刷头10与刷柄较好的连接，从而方便安装电动牙刷头10从刷柄上安装和拆卸，而且传动轴21伸入刷头壳体100内部，因此保证了传动轴21带动电动牙刷头10摆动的效果。
为了便于安装和拆卸配重件300，在一个实施例中，如图2所示，所述安装腔102的远离所述安装口121的一端可以与所述容置腔101连通，由于容置腔101与安装腔102连通，也即与安装口121连通，因此可以将配重件300从安装口121取出，实现配重件300的拆卸，或者将配重件300从安装口121放进，直至到达容置腔101，实现配重件300的安装。
为了使得连接端120与传动轴21稳定连接，在一个实施例中，如图2所示，所述安装腔102中可以设有内衬件400，所述内衬件400可以开设有安装孔401，所述安装孔401与所述安装腔102连通，所述安装孔401可以用于安装所述传动轴21，所述安装孔401的内壁可以用于与所述传动轴21抵紧，通过内衬件400的安装孔401的内壁与传动轴21抵紧，使得传动轴21与刷头壳体100的连接稳固，使得电动牙刷头10被传动轴21稳定带动进行摆动，保证了电动牙刷头10的清洁效果。在一个实施例中，所述内衬件400可以与所述安装腔102的内壁连接或者抵紧。在一个实施例中，所述内衬件400可拆卸设置于所述安装腔102中。
为了进一步保证连接端120与传动轴21稳定连接，在一个实施例中，如图2所示，所述内衬件400可以包括相连接的内衬本体410和卡接部420，所述内衬本体410可以开设所述安装孔401，所述卡接部420可以用于卡设于所述传动轴21上开设的卡槽中，在传动轴21设置在安装孔401中且 与安装孔401的内壁抵紧时，内衬本体410上的卡接部420卡设在传动轴21上的卡槽中，进一步保证传动轴21与内衬本体410的紧密且稳固地连接，进一步保证了连接端120与传动轴21稳定连接；而且将卡接部420设置在内衬本体410上，即卡槽开设在传动轴21上，这样传动轴21设置的不是卡接部420，而是卡槽，因此便于传动轴21穿过安装口121进入到安装腔102中以及安装孔401中，也便于传动轴21从安装口121脱离出去。在一个实施例中，所述卡接部420可以凸设于所述安装孔401的内壁，所述卡槽可以开设于所述传动轴21的侧面，这样便于卡接部420与卡槽相配合。在一个实施例中，所述卡接部420可以位于所述安装孔401的内部边缘。
为了便于卡接部420与卡槽解除配合，在一个实施例中，如图1所示，所述卡接部420可以为楔形结构，所述卡接部420可以用于与楔形的所述卡槽相配合，这样在传动轴21从安装孔401脱离的过程中，楔形的卡接部420便于从楔形的卡槽中滑出，便于卡接部420与卡槽解除配合，从而便于内衬件400与传动轴21脱离连接，即便于电动牙刷头10与传动轴21脱离连接。
为了更加便于安装和拆卸配重件300，在一个实施例中，所述刷头壳体100的侧面还可以开设有开口，所述开口可以与所述容置腔101连通，所述刷头杆还可以包括密封盖，所述密封盖可以与所述刷头壳体100连接，且所述密封盖可以活动封设所述开口，由于在刷头壳体100的侧面开设了开口，且开口与容置腔101连通，因此可以从开口进行配重件300的安装和拆卸，即可以进行配重件300的更换，从而可以适应不同电动牙刷的动力输出要求，对于从开口处拆装配重件300，更加方便快捷，密封盖则可以在安装好配重件300后将开口封住，防尘防水。为了保证配重件300可拆卸的同时又能使得配重件300可以稳固设置在容置腔101中，在一个实施例中，所述配重件300可以卡设于所述容置腔101中或者粘接于所述容置腔101的内壁上，这样保证了配重件300可拆卸的同时又能使得配重件300可以稳固设置在容置腔101中，避免刷头壳体100摆动时使得配重件300在容置腔101中发生碰撞，使得电动牙刷头10整体可以稳定摆动。
为了便于刷毛件200牢固设置在刷毛端110且便于更换刷毛件200，在一个实施例中，如图1和图2所示，所述刷毛件200可以包括连接部210和多个刷毛部220，所述连接部210可以包括相背的安装面211和连接面212，所述刷毛端110的侧面可以开设有安装槽111，所述连接部210可以位于所述安装槽111中，且可以与所述安装槽111的内壁可拆卸连接，所述安装面211与所述安装槽111的底部可拆卸连接，所述刷毛部220可以设置于所述连接面212上，这样使得刷毛部220设置在刷毛端110的侧面，便于刷毛端110摆动时，刷毛部220能有效清洁到牙齿；通过连接部210设置在安装槽111中，使得刷毛件200牢固地设置在刷毛端110，而且连接部210可拆卸设置在安装槽111中，因此便于更换刷毛件200。在一个实施例中，所述连接部210可以卡设于所述安装槽111中或者所述连接部210与所述安装槽111的内壁粘接，这样保证了刷毛件200可拆卸又能使得刷毛件200稳固设置在安装槽111中。在一个实施例中，所述连接部210位于所述安装槽111中时，所述连接面212可以与所述刷毛端110的侧面齐平，这样使得刷毛端110的侧面没有凸起或者凹陷，整体平滑，避免对使用者的口腔造成伤害。
如图3所示，一种电动牙刷30，可以包括刷柄20和如上述任一实施例所述的电动牙刷头10， 所述刷柄20上可以设有传动轴21，所述连接端120可以与所述传动轴21的远离所述刷柄20的一端连接。
上述的电动牙刷30，可以包括电动牙刷头10，由于在刷头壳体100内部开设的容置腔101中设置了配重件300，即给刷头壳体100的摆动配重，能有效降低与刷头壳体100连接的刷柄20的震动以及保证噪音尽可能小，而且由于配重件300邻近刷毛端110设置，即配重件300远离连接端120设置，因此避免影响传动轴21对刷头壳体100的带动作用，此外由于配重件300是可拆卸设置在容置腔101中的，因此便于更换不同的配重件300以适应不同的减震减噪需求。
为了进一步保证连接端120与传动轴21稳定连接，在一个实施例中，所述内衬件400可以包括相连接的内衬本体410和卡接部420，所述内衬本体410可以开设所述安装孔401，所述传动轴21可以开设有卡槽，所述卡接部420可以卡设于所述卡槽中，在传动轴21设置在安装孔401中且与安装孔401的内壁抵紧时，内衬本体410上的卡接部420可以卡设在传动轴21上的卡槽中，进一步保证传动轴21与内衬本体410的紧密且稳固地连接，进一步保证了连接端120与传动轴21稳定连接；而且将卡接部420设置在内衬本体410上，即卡槽开设在传动轴21上，这样传动轴21设置的不是卡接部420，而是卡槽，因此便于传动轴21穿过安装口121进入到安装腔102中以及安装孔401中，也便于传动轴21从安装口121脱离出去。在一个实施例中，所述卡接部420可以凸设于所述安装孔401的内壁，所述卡槽可以开设于所述传动轴21的侧面，这样便于卡接部420与卡槽相配合。
为了便于卡接部420与卡槽解除配合，在一个实施例中，所述卡接部420可以为楔形结构，所述卡槽为楔形槽，所述卡接部420可以与楔形的所述卡槽相配合，这样在传动轴21从安装孔401脱离的过程中，楔形的卡接部420便于从楔形的卡槽中滑出，便于卡接部420与卡槽解除配合，从而便于内衬件400与传动轴21脱离连接，即便于电动牙刷头10与传动轴21脱离连接。在一个实施例中，所述卡接部420的纵截面和所述卡槽的纵截面可以分别为三角形状。
