Description

双向电动剃须刀 技术领域
本发明涉及一种剃须刀，具体涉及一种双向电动剃须刀。
 背景技术
电动剃须刀是剃除胡须的电器设备，包括机身以及由动力传动机构驱动旋转的刀头，所述刀头包括多组刀头组件，刀头组件通常包括静刀、动刀、动刀定位件、动刀支架等。
目前，大多数剃须刀的各组刀头组件结构都是相同的，并单向转动，但是当胡须与刀头组件旋转方向相同时，胡须不易进入静刀网，无法达到最佳的剃须效果，为解决上述问题，设计出了一种双向电动剃须刀，如中国实用新型专利（CN2647519Y）公开的四头双向电动剃须器，其内切刀网下有上下左右四个旋转内切刀头，左右两个旋转刀头以同一方向转动，上下两个旋转刀头则以与左右两个旋转刀头相反的方向转动，从而提高剃须效率。
但是上述剃须器，其上下左右四个旋转刀头结构相同，旋转刀头上的刀齿水平设置，无法达到自研磨效果，剃须效果会随着产品的使用越来越差，为解决该问题，往往又会将动刀的切割部设置成与其旋转方向相匹配的倾斜结构，以实现自研磨，保证剃须效果，提高使用寿命。
 技术问题
但是设置倾斜结构的切割部，便会使得不同转向的动刀上切割部的方向也会不同，一旦动刀上切割部的倾斜方向与其旋转方向不匹配，则会彻底损坏刀头，而且会导致严重的夹须问题。
特别是用户在使用剃须刀时，是经常会对剃须刀刀头进行拆卸并进行清洗的，但是用户本身可能无法判断刀头的正确安装位置，也不清楚装错刀头带来的严重后果，因此非常容易出现错装现象。

其中，所述第一刀头组件2包括第一动刀21、第一动刀定位件22、第一动刀支架23、第一驱动连接件24、第一静刀25，所述第一动刀21安装在第一动刀定位件22上，所述第一动刀定位件22通过第一动刀支架23安装在动刀支架上，且第一动刀定位件22通过第一驱动连接件24连接动力传动机构，所述第一静刀25浮动安装在静刀支架上，并与第一动刀21对应设置。
所述第二刀头组件3包括第二动刀31、第二动刀定位件32、第二动刀支架33、第二驱动连接件34、第二静刀35，所述第二动刀31安装在第二动刀定位件32上，所述第二动刀定位件32通过第二动刀支架33安装在动刀支架上，且第二动刀定位件32通过第二驱动连接件34连接动力传动机构，所述第二静刀35浮动安装在静刀支架上，并与第二动刀31对应设置。
所述动力传动机构包括电机41、输入齿轮42、第一输出齿轮43、第二输出齿轮44、中间传动齿轮45；所述电机41驱动连接输入齿轮42，所述第一输出齿轮43与输入齿轮42相啮合，所述第一输出齿轮43连接第一驱动连接件24；所述中间传动齿轮45与输入齿轮42相啮合，所述第二输出齿轮44与中间传动齿轮45相啮合，所述第二输出齿轮44连接第二驱动连接件34，通过上述动力传动机构传动，使得第一动刀21与第二动刀31的旋转方向相反。
同时，所述第一动刀21上设有若干周向均布并倾斜布置的第一切割部212，所述第二动刀31上设有若干周向均布并倾斜布置的第二切割部312，所述第一切割部与第二切割部的倾斜方向相反，通过不同朝向的切割部以及不同的旋转方向，以达到更好的剃须效果。
进一步的，为了避免用户对刀头进行拆卸清洗后，重新组装装错，在所述第一刀头组件2与第二刀头组件3上对应设置若干防错装结构，对第一刀头组件2与第二刀头组件3的各个部件的安装进行有效区分。
如图6、图9、图11所示，所述第一驱动连接件24顶部形成有第一连接头241，所述第一连接头241的横向截面呈三角形，所述第一动刀定位件22底部对应设置有第一安装槽223，通过相匹配的第一连接头241与第一安装槽223形成第一连接结构连接第一动刀定位件22与第一驱动连接件24。
所述第二驱动连接件34顶部形成有第二连接头341，所述第二连接头341的横向截面呈矩形，所述第二动刀定位件32底部对应设置有第二安装槽323，通过相匹配的第二连接头341与第二安装槽323形成第二连接结构连接第二动刀定位件32与第二驱动连接件34。
第一连接头241采用三角形的结构，第二连接头341则采用矩形的结构，使得第一动刀定位件22无法安装在第二驱动连接件34，第二动刀定位件32无法安装在第一动刀定位件22，而且结构简单、直观，达到更好的防错装的效果。
当然，图6、图9、图11所示的仅代表一种实施例的结构，除此之外，还可以采用不同形式的第一连接结构和第二连接结构进行区分，如第一驱动连接件设置连接头的结构，而第二驱动连接件则设置安装槽的结构。
还可以采用其他形状的第一连接头与第二连接头的横向截面形状，不局限于三角形和矩形的区别。
还可以是同样的形状结构，仅仅在于改变尺寸，那么大尺寸的连接头无法装进小尺寸的安装槽内，以此实现防错装的目的。
另外，由于所述第一动刀定位件22、第一驱动连接件24、第二动刀定位件32、第二驱动连接件34均一体注塑成型，所以还可以通过注塑成指定的颜色，所述第一动刀定位件22与第一驱动连接件24颜色相同，所述第二动刀定位件32与第二驱动连接件34颜色相同，同时第一动刀定位件22与第二动刀定位件32颜色不同，根据颜色进行相应配对，能够更加直观的进行区分，避免错装。
如图2、图4-5、图7-8所示，所述第一动刀定位件22是直接一体注塑在第一动刀21上的，所述第一动刀21中心形成有呈圆形的第一安装孔211，所述第一动刀定位件22外圈对应设置有呈环形的第一安装部221，通过相匹配的第一安装孔211与第一安装部221形成第三连接结构连接第一动刀21与第一动刀定位件22。
所述第二动刀31与第二动刀定位件32相互套接，所述第二动刀31中心形成有呈六边形的第二安装孔311，所述第二动刀定位件32外圈对应设置有呈六边形的第二安装部321，通过相匹配的第二安装孔311与第二安装部321形成第四连接结构连接第二动刀31与第二动刀定位件32。
第一动刀21与第一动刀定位件22之间以及第二动刀311与第二动刀定位件32之间分别通过不同的形状、不同的定位方式达到多重放错的效果，使得在生产组装的过程中，就得到很好的区别，避免错装。
当然，如图2、图4-5、图7-8所示的仅代表一种实施例的结构，除此之外，也可以是仅在形状上进行区别，也可以采用同样的结构，不同的尺寸进行区别。
如图3、图5、图8所示， 所述第一静刀25底部中心设有圆形凸台251，所述第一动刀定位件22端部设有相对应的定位凹槽222，通过相匹配的圆形凸台251与定位凹槽222形成第一定位结构，使得第一动刀与第一静刀对应配合。
所述第二静刀35底部中心设有圆形凹槽351，所述第二动刀定位件32端部设有相对应的定位凸台32，通过相匹配的圆形凹槽351与定位凸台32形成第二定位结构，使得第二动刀与第二静刀对应配合。
由于第一动刀的第一切割部212与第二动刀的第二切割部312反向相反，旋转方向相反，因此第一静刀25与第二静刀35上的进须孔的朝向也是不同的，因此第一静刀25与第二静刀35也是必须安装正确，通过不同结构的第一定位结构与第二定位结构，结构简单、直观，达到更好的防错装的效果。
当然，如图3、图5、图8所示的仅代表一种实施例的结构，除此之外，也可以在第一定位结构与第二定位结构的尺寸上进行区别。
另外，如10所示，所述第一刀头组件2还包括用于支撑第一动刀定位件22的第一动刀支架23，所述第二刀头组件3还包括用于支撑第二动刀定位件32的第二动刀支架33，所述第一动刀支架23与第二动刀支架33的形状不一致，如所述第一动刀支架23呈椭圆形结构，所述第二动刀支架33呈圆形结构。
通过不同形状的第一动刀支架23与第二动刀支架33实现进一步的区分，若用户误装，动刀支架将无法锁定，无法进行下一步操作，从而达到防错装的效果。
实施例不应视为对发明的限制，但任何基于本发明的精神所作的改进，都应在本发明的保护范围之内。
