本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
请参阅图1至图7，本发明实施例提供一种浮动剃须刀，包括刀头组件100以及机身组件200。
刀头组件100包括头盖110、切削结构120、导电浮动件130和导电体140（图中未示出）。
头盖110用于与具有电路板组件的机身组件200连接，头盖110在浮动方向上开设有贯通设置的导电孔1101。
切削结构120用于切削毛发，具体地切削结构120包括活动连接于头盖110上的刀架121以及安装于刀架121上的切削单元122，切削单元122包括安装于刀架121的刀网1221及设于刀网1221内的转动刀头1222。
导电浮动件130用于将头盖110和切削结构120电连接，具体地导电浮动件130包括连接部131以及至少两个弹性臂132，导电孔1101与连接部131在浮动方向相对设置，连接部131安装于头盖110，连接部131和电路板组件之间具有电性连接，各弹性臂132的一端均连接于连接部131的周侧，并朝远离头盖110的方向延伸设置，各弹性臂132的另一端分别抵接一个切削结构120，弹性臂132的另一端能够相对于头盖110在浮动方向上移动。
导电体140贯穿导电孔1101，基于此结构设计，所述切削结构120作为第一导电通路的第一端，所述第一导电通路用于在所述切削结构120接近或接触人体皮肤时接收所述切削结构120与大地之间的第一感应电容，并依次经所述导电浮动件130、所述导电体140传递至所述电路板组件；所述电路板组件用于在接收到所述第一感应电容时启动电机。
在一个实施例中，所述刀架121作为第一导电通路的第一端，所述第一导电通路用于在所述刀架121接近或接触人体皮肤时接收所述刀架121与大地之间的第一感应电容，并依次经所述导电浮动件130、所述导电体140传递至所述电路板组件。
在另一个实施例中，所述刀网1221作为第一导电通路的第一端，所述第一导电通路用于在所述刀网1221接近或接触人体皮肤时接收所述刀网1221与大地之间的第一感应电容，并依次经所述导电浮动件130、所述导电体140传递至所述电路板组件。
具体地，导电体140还可以包括第一导体141和第二导体142，其中第一导体141滑动连接于导电孔1101，第二导体142为弹性件，第二导体142位于导电孔1101内，并弹性抵接连接部131，第二导体142远离连接部131的一侧弹性抵接第一导体141。
基于此结构设计，刀架121或刀网1221作为第一导电通路的第一端，第一导电通路用于在刀架121（或刀网1221）接近或接触人体皮肤时接收刀架121（或刀网1221）与大地之间的第一感应电容，并依次经导电浮动件130、第二导体142和第一导体141传递至电路板组件，电路板组件电性连接于第一导电通路的第二端且用于在接收第一感应电容时启动电机。
本发明提供的浮动剃须刀，与现有技术相比，参阅图1，该浮动剃须刀包括刀头组件100与机身组件200。浮动剃须刀配置有第一导电通路，第一导电通路的第一端是刀头组件100中的刀架121或刀网1221。第二端连接至手柄组件220中的电路板组件。剃须时，将刀架121或刀网1221贴近下颚、脸颊等人体皮肤；由于人体皮肤带有一定电荷，当人体皮肤直接接触或贴近刀架121或刀网1221时，刀架121或刀网1221会从接近位置吸收与大地之间形成的人体皮肤电容，也就是第一感应电容。在电路板组件接收第一感应电容时，即启动电机以通过齿轮仓210带动切削单元112中的转动刀头1222转动，进行剃须，避免了通常因机械开关按键损坏或失灵而导致剃须刀无法正常工作的问题，从而确保剃须装置能够长时间可靠使用。
在本发明实施例中，导电浮动件130在与各刀架121电连接结合第一导体141和第二导体142即可将第一感应电容传递至所述电路板组件以起到导电作用的同时，还起到使各切削结构120能够相对头盖110浮动的作用。
在此需要说明的是，为实现连接部131和电路板组件之间的电性连接，请参阅图4和图5，可通过一个导电结构件（即图中的第三导体212）抵接导电孔1101即可电连接至第一导体141。
在此需要说明的是，如第一导体141安装于头盖110，为保证第一导体141与导电结构件电连接，第一导体141与导电结构件之间需要紧密接触，导电结构件需要抵顶第一导体141。基于此结构设计，导电结构件（即图中的第三导体212）抵顶第一导体141时，第一导体141会向连接部131的方向移动，由于第二导体142为弹性件，第二导体142会在浮动方向上进行形变，即在浮动方向上的尺寸缩小，如此，可避免第一导体141会发生位移，并在导电浮动件130撤销抵顶后，也由于第二导体142为弹性件，第二导体142会复位，避免了第一导体141发生位置偏移的情况，从而始终保证第一导体141位置不发生偏移，能够一直与导电结构件（第三导体212）紧密抵接。
在具体实施例中，第一导体141优选为浮动针，如此，第一导体141本身受到导电结构件抵顶时，其在浮动方向上会发生位移，并在导电结构件的挤压撤销时复位；第二导体142优选为螺旋弹簧，螺旋弹簧在市面上具有各种尺寸规格、性能的标准件，如此，可以不用专门生产制造，有利于降低生产制造成本。
一个实施例中，请参阅图3和6，弹性臂132远离连接部131的另一端设有抵接部133，抵接部133呈弧状设置，且其凸点抵接刀架121。在切削结构120浮动过程中，弹性臂132远离连接部131的另一端与刀架121会发生相对位移，如弹性臂132远离连接部131的另一端通过凸尖结构与刀架121抵触，在此过程中，会磨损刀架121，而基于此结构，导电浮动件130通过抵接部133与刀架121抵触，抵接部133呈弧状设置，且其凸点抵接刀架121，使得导电浮动件130通过圆滑结构来与刀架121抵触，可有效降低浮动件磨损刀架121。
一个实施例中，请参阅图1，导电孔1101的孔壁凸设有限位凸起112，限位凸起112防止第一导体141从导电孔1101脱离。基于此，在装配过程中，将第一导体141置入到导电孔1101后，再将连接部131固定到头盖110，即完成第一导体141的装配，无需其他结构紧固，有利于提高装配效率。
在本实施例中，限位凸起112沿导电孔1101的孔壁周向环形设置。
一个实施例中，连接部131开设有至少一个贯通设置的固定孔1311；头盖110设有至少一个固定件，各固定件分别穿设于一个固定孔1311，具体地各固定件还可包括连接于头盖110并沿浮动方向延伸设置的固定柱以及连接于固定柱远离头盖110的一端的铆压头，各固定柱分别穿设于一固定孔1311，各铆压头均抵接连接部131背离头盖110的侧面。在连接部131装配至安装之前，固定件尚未形成，优选地，在头盖110设有至少一个固定坯柱111，通过各固定坯柱111的自由端进行铆压，其中，铆压变形的部分形成铆压头，而未铆压的部分则为固定柱。
具体地，各固定柱的截面形状分别与对应的固定孔1311的孔形相匹配，在各固定柱穿过对应的定位孔后，可限制连接部131在垂直于固定柱中心轴线的方向移动。
在其他实施例中，连接部131与头盖110之间的连接为可拆卸连接，具体可采用螺钉实现可拆卸连接。
一个实施例中，刀架121包括刀架本体以及连接于刀架本体周侧的抵接凸起，抵接凸起与对应的弹性臂132抵接。基于此结构设置，该刀架121本体的结构设计可以为现有的刀架121的结构设计，也即是可以在现有刀架121的结构基础上，在其周侧增加抵接凸起来实现本发明的刀架121，有利于减少刀架121的结构改进。具体地，在本发明实施例中，抵接凸起呈板片结构。
一个实施例中，在刀架121或刀网1221作为第一导电通路的第一端时，刀架121为导电材料体。直接采用导电材料制作刀架121容易加工。或者，刀架121的外表面设有导电层。通过在塑料件外表面设置导电层形成的刀架121，重量会更轻。类似地，在刀网1221作为第一导电通路的第一端时，刀网1221为导体；或者，刀网1221的外表面设有导电层。两种制作方式均能作为第一导电通路的第一端，刀架121(或刀网1221)会从与人体皮肤的接近位置吸收与大地之间形成的人体皮肤电容。
一个实施例中，齿轮仓210用于机身组件200连接，且还用于与前述的刀头组件100连接，齿轮仓210包括齿轮仓主体211以及安装于齿轮仓主体211的第三导体212，第三导体212能够从导电孔1101远离连接部131的孔口抵接导电孔1101，第三导体212与导电体140电连接；基于此结构设计，第一感应电容依次经导电浮动件130、导电体140和第三导体212传递至电路板组件，另外由于导电体140还包括第二导体142和第一导体141，基于此结构设计，第一感应电容依次经导电浮动件130、导电体140和第三导体212传递至电路板组件。
在另一个实施例中，请参阅图1和图8，齿轮仓主体211包括齿轮固定架2111、安装齿轮固定架2111朝向刀头组件100的齿轮架盖板2112以及安装于齿轮固定架2111和齿轮架盖板2112之间并用于将机身组件200的电机的动力传递至各切削结构120的齿轮组2113；齿轮架盖板2112作为第二导电通路的第一端，第二导电通路用于在齿轮架盖板2112接近或接触人体皮肤时接收齿轮架盖板2112与大地之间的第二感应电容，并传递至电路板组件。剃须时，由于人体皮肤带有一定电荷，当人体皮肤直接接触或贴近齿轮架盖板2112时，齿轮架盖板2112会从接近位置吸收与大地之间形成的人体皮肤电容，也就是第二感应电容。在电路板组件接收第二感应电容时，即启动电机以通过齿轮仓210带动切削单元112中的转动刀头1222转动，进行剃须，如此，可以不需要刀架121或刀网1221与大地形成第一感应电容即可启动电机。尤其是当因故障等因素导致刀架121或刀网1221与大地无法形成第一感应电容时，可以利用齿轮架盖板2112与大地之间形成的第二感应电容来启动电机。
一个实施例中，齿轮架盖板2112为导体，直接采用导电材料制作齿轮架盖板2112容易加工。或者，齿轮架盖板2112的外表面设有导电层。通过在塑料件外表面设置导电层形成的齿轮架盖板2112，重量会更轻。
一个实施例中，外壳作由导电材料制成，外壳作为第三导通电路的第一端，第三导电电路在外壳接近或接触人体皮肤时接收外壳与大地之间的第三感应电容，并传递至电路板组件；电路板组件电性连接于第三导电通路的第二端且用于在接收第三感应电容时使电机处于待机状态；电路板组件用于在一并接收到第一感应电容和第三感应电容时启动电机。基于此结构设计在电路板组件接收到第三感应电容的基础上接收到第一感应电容时才会启动电机，有利于避免人体误触外壳而直接启动电机。
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本发明的保护范围之内。
