为了说明本发明所述的技术方案，以下结合具体附图对本发明提供的一种充电防水结构的实现通过具体实施例进行详细说明。
请参考图1，本发明实施例以剃须刀为例介绍其内的充电防水结构，需要说明的是，充电防水结构也可以应用其他个人护理产品上，如脸部按摩仪、理发剪、电动牙刷等等。
本实施例中，剃须刀包括机身（图中未示出），机身具有外壳（图中未示出），而在外壳内再设置上述的充电防水结构。具体地，充电防水结构包括壳体10以及设于壳体10内的控制组件（图中未示出）。此处，壳体10可看作剃须刀的内壳，通过内壳与外壳提供双重保护作用。为了便于壳体10内控制组件的装配，以及便于壳体10本身的加工制作，将壳体10分为底壳11与盖体12，二者围合后内部具有密闭的容纳腔13。本实施例中，在容纳腔13的一侧且位于壳体10外部，具体地，位于底壳11外侧设有安装口14。控制组件包括位于容纳腔13的主板20、设于安装口14处的充电接口组件30以及穿设于容纳腔13与安装口14之间用于电连接主板20与充电接口组件30的电连接件40，安装口14处且位于充电接口组件30与底壳11之间设有密封组件50。
本实施例中，将控制组件拆分为主板20以及充电接口组件30，且将主板20设置在密封的容纳腔13内，而将充电接口组件30设置在壳体10外的安装口14处，这样将控制组件进行拆分，将整个产品的渗水风险进行了分级化解，即使出现渗水现象，也只可能影响位于安装口14处的充电接口组件30，而不会影响位于容纳腔13内的主板20，不会出现短路、接触不良的情况，且在此情况下，只需更换充电接口组件30即可，不需维修或更换主板20，节省了维修成本；同时针对安装口14处的充电接口组件30特别设置密封组件50来进行密封，也进一步降低充电接口组件30出现渗水的风险；而且上述的充电防水结构简单，便于组装，应用于剃须刀或其他个人护理产品时，使得整机产品的防水等级提升至IPX7，且维修成本降低，性价比高，提升产品的市场竞争力。
参照图2，充电接口组件30包括充电电路板31，以及电连接于充电电路板31上的充电接口32及充电连接套33。其中，充电接口32于安装口14处裸露用于与外部电源线插接，充电连接套33与电连接件40电连接，而电连接件40又与容纳腔13内的主板20连接，从而实现外部电源与主板20的电连接，实现产品的充电功能。由于充电接口32为与外部连通的窗口，为可能渗水的重要部位，因此，将密封组件50设置在充电接口32与安装口14之间，降低外部水由充电接口32与安装口14之间进入壳体10内的可能。
进一步地，本实施例中，充电接口32优选为type-c接口。type-c接口为对称接口，在插接时不需考虑对位方向，解决USB接口永远插不准的难题，可以实现盲插，尤其方便在夜间或光线较暗的环境中使用。当然，基于成本或具体应用群体的需求，充电接口32也可以为普通的USB接口。
而本实施例中，在基于充电接口32为type-c接口的前提下，对密封结构进行一系列改进。现有的type-c接口中防水结构均设置在type-c接口上，例如在type-c接口上设置防水软胶部，这样的结构设计导致type-c接口制作工艺复杂，防水可能性没有明显提高，且成本偏高。而本实施例，在与type-c接口装配的壳体10结构上设置多重防水密封结构，在降低成本的同时，提升密封等级。
具体地，参照图2，充电电路板31呈平板状，type-c接口居中置于充电电路板31上。充电连接套33为两个，对称设于type-c接口两侧。相应地，充电连接套33也为两个。将充电连接套33对称设置在type-c接口两侧，不仅能更好地利用两充电连接套33与两电连接件40连接，而且，也能使充电接口32组件30在安装于安装口14时更稳固、可靠。装配时，分别将充电接口32及两充电连接套33焊接于充电电路板31上。
本实施例中，将充电接口32及两充电连接套33焊接于充电电路板31后，将充电电路板31上进行纳米镀膜处理，使装配完成的充电电路板31表面具有纳米镀膜层（图中未示出）。纳米镀膜层具有疏水性，即使有水汽进入安装口14后也不会有水滴附着在纳米镀膜层，具有较好的防潮、防水效果，此处实现第一重防水。
进一步地，在将上述焊接完成的充电接口32组件30安装于安装口14后，于type-c接口与安装口14之间设置密封组件50实现第二重防水。具体地，参照图3至图5，密封组件50包括设于type-c接口外侧的防水盖板51以及防水密封圈52，防水盖板51上设有开口511，type-c接口插入开口511中，而防水密封圈52位于开口511处且围绕type-c接口。
本实施例中，为进一步增强密封效果，同时避免防水密封圈52于type-c接口上脱落，防水密封圈52与充电接口32之间过盈配合。防水密封圈52采用具有弹性的塑胶材质制成，当其过盈挤压安装在type-c接口与开口511之间后，其弹性回复，利用其弹性回复力牢固抵接在且在type-c接口外壁与开口511内壁之间，使防水密封圈52的外壁与开口511内壁之间无缝隙紧密贴合，同时，防水密封圈52的内壁与type-c接口外壁之间无缝隙紧密贴合，从而使第二重防水密封效果更好。
参照图6、图7，容纳腔13的腔壁上设有可供电连接件40穿过的连接孔131，电连接件40与连接孔131过盈配合。容纳腔13与安装口14之间通过容纳腔13壁隔离，而连接孔131作为内、外两部分的连接通道，存在渗水的可能，而将电连接件40过盈安装于连接孔131内，使电连接件40外壁与连接孔131内壁之间实现无缝隙紧密贴合，从而实现第三重防水。
在装配时，先将电连接件40过盈安装于连接孔131内，再将上述的充电接口32组件30安装于安装口14处，并将电连接件40与充电接口32组件30上的充电连接套33电连接。本实施例中，充电连接套33上设有弹性开口331，电连接件40的一端卡入弹性开口331内。优选地，电连接件40为圆柱状的充电针。这样，充电针圆滑的外壁更容易卡入弹性开口331内。装配时，将充电针对准弹性开口331按压，即可在外力作用使弹性开口331张开，当充电针完全卡入后，弹性开口331弹性自动实现与充电针的过盈连接，避免充电针由弹性开口331处滑脱，实现充电针与充电连接套33之间可靠的电连接，使得在充电时不会出现接触不良的现象。
参照图8、图9，主板20上设有与电连接件40即充电针电连接的充电接触片60。故充电接触片60也对应为两个，与两充电针一一对应，每个充电接触片60的设置方向是朝向对应的充电针，每个充电接触片60上设有开口朝向充电针的插槽61，充电针的另一端即远离充电接口32组件30的一端过盈卡入插槽61内。如图7所示，在装配时，将充电针安装于连接孔131后，将主板20上具有充电接触片60的一侧朝下安装，使充电针卡入插槽61内。结合图9可以看出，充电针表面设有若干环状凸起41，这样，充电针与插槽61安装，充电针与连接孔131安装，以及充电针与弹性开口331安装后，环状凸起41能进一步限制充电针在轴向方向上的位置，使充电针的安装更稳固。
请再参照图10，本实施例中，在底壳11的顶面，即与盖体12对接的对接面上设有密封槽111，密封槽111内嵌设有密封筋条（图中未示出）。此处通过设置密封筋条，实现底壳11与盖体12之间的无缝密封连接，从而实现第四重防水。当然，也可以将密封筋条设置在盖体12与底壳11的对接面。本实施例中，底壳11与盖体12的安装，一端通过连接件（图中未示出）紧固连接，另一端即靠近充电接口32组件30的一端通过卡扣结构卡接。具体地，在底壳11的此端部设置两卡扣112，而在盖体12对应的端部设置两卡钩121，通过两卡钩121与两卡扣112的配合实现卡接，这样拆、装方便。
综上，本实施例中，充电防水结构在结构简单，易于装配的前提下，通过至少四重防水结构提升防水密封等级，降低了维修成本，性价比高，提升产品的市场竞争力。
以上仅为本发明的优选实施例而已，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权利要求范围之内。
