实用新型内容
为解决上述现有技术的缺陷和不足，本实用新型目的是提供一种新型弧面式电动剃须刀。
实现本实用新型目的的一种新型弧面式电动剃须刀，包括刀身、刀头和传动机构，刀头包括刀头本体、动刀、刀网和动刀支架，其特征在于，刀头本体呈柱状结构，刀头本体与刀身固定连接，刀头本体内设置有容纳腔，容纳腔在刀头本体的柱面处设有第一开口，动刀和动刀支架设置在容纳腔内，刀网放置在容纳腔内并且刀网的网面部从容纳腔的第一开口处露出，动刀支架上还包括有弹性部件，动刀架设在动刀支架上并且可以通过弹性部件进行浮动，刀身内设置有电机，电机的输出轴通过传动机构连接至动刀，动刀做与刀网的网面部内侧横向相切的旋转运动或圆弧往复式运动。
进一步的，所述刀头本体的下端部处还设置有活动连接的端盖，刀头本体通过端盖与刀身固定连接，所述容纳腔在刀头本体与端盖连接的下端面处设置有第二开口。
进一步的，所述动刀呈圆柱状结构，动刀在顶端面处和底端面处设置有旋转支撑凸台，所述动刀支架上还设置有动刀支撑部，所述旋转支撑凸台卡持固定在动刀支撑部上。
进一步的，所述动刀支撑部为从动刀支架的上表面处伸长出的两个镜像设置的柱体。
进一步的，所述刀网的底部侧壁处设置有卡持槽，刀网通过卡持槽与动刀进行固定，刀网可随着动刀通过所述弹性部件进行浮动。
进一步的，所述弹性部件为弹簧、弹片、弹力皮筋或弹力棉中的一种。
进一步的，所述刀身内设置有腔体，所述电机设置在腔体内，电机的输出轴上设置 有与所述传动机构匹配连接的连接杆。

具体实施方式
结合图1至图5所示，一种新型弧面式电动剃须刀，包括刀头(1)、刀身(2)和传动机构(3)。
刀头(1)由刀头本体(11)、动刀(12)、刀网(13)和动刀支架(14)组成。其中，刀头本体(11)采用塑胶材料通过注塑工艺制成，刀头本体(11)整体呈圆柱状结构，在刀头本体(11)内设置有容纳腔(112)，容纳腔(112)沿着柱体轴向设置，容纳腔(112)在刀头本体柱面处具有第一开口，第一开口呈长方形形状，刀头本体(11)在容纳腔(112)的第一开口处还设置有往容纳腔(112)内侧方向伸长的阻挡部(113)，阻挡部(113)呈薄壁状并分布在第一开口处沿着刀头本体(11)轴向的两侧；刀头本体(11)在接近容纳腔(112)底部的两个侧壁上分别设置有相对称的导向卡紧筋(114)，导向卡紧筋(114)的方向沿着刀头本体(11)的柱体轴向。
进一步的，刀头本体(11)的下端部处还设置有一个端盖(111)，端盖(111)的上端部通过螺纹绞合方式与动刀本体(11)活动连接，端盖(111)的中部设置有一个通过孔(1111)，通过孔(1111)穿透过端盖(111)的上端面和下端面，端盖(111)的下端部设置有一个安装部(1112)，安装部(1112)被用于与刀身(2)进行连接固定用途。在端盖(111)与动刀本体(11)连接部位处，容纳腔(112)还设置有第二开口，容纳腔(112)通过第二开口与通过孔(1111)形成互通。
动刀支架(14)由刚性塑胶材料制成，其底部为一块平板，在平板上的相对两端部分别往上伸长出一个动刀支撑部(141)，动刀支撑部(141)为两个镜像构造的柱体，两个柱体相对的两个柱面为圆弧形凹面构造结构，两个柱体的顶端还设置有向内侧伸长的凸角(1411)，动刀支架(14)上还设置有弹性部件(142)，本实施例中，弹性部件(141)为弹簧，弹簧放置在动刀支撑部(141)两个镜像构造的柱体之间，并且利用柱体之间的圆弧形凹面进行包裹固定。
动刀(12)呈圆柱状结构，动刀(12)在其顶端面处和底端面处对称设置有呈圆柱形结构的旋转支撑凸台(121)，并且旋转支撑凸台(121)设置在动刀(12)的轴心线上以保持旋转均衡稳定；动刀(12)在柱面处设置有刀刃，刀刃用于刮断胡须用途；动刀(12)通过旋转支撑凸台(121)卡持固定在动刀支撑部(141)上，并且旋转支撑凸台(121)抵触在弹性部件(142)的上端面，并且旋转支撑凸(121)台通过动刀支撑部(141)中的柱体顶端的凸角(1411)进行限位，不从动刀支撑部(141)中脱出。
刀网(13)由钢片通过裁剪冲压工艺制成，刀网(13)整体呈倒立放置的槽形结构，刀网(13)的顶部为圆弧柱面结构的网面部(131)，网面部(131)的弧度与所述动刀(12)柱面的弧度相同，网面部(131)处设置有用于胡须通过的刀口；刀网(13)的底部为四个侧壁围成的槽形壁面，槽形口呈长方形形状，刀网(13)在其中相对的两个较短侧壁上设置 有卡持槽(132)，刀网(13)通过卡持槽(132)卡持在动刀(12)的旋转支撑凸台(121)上；通过结构设计，刀网(13)的槽形结构内部空间尺寸大于动刀(12)外形轮廓尺寸，可以使得刀网(13)整体罩住动刀(12)并且不会干涉到动刀(12)的运动。
当需要组装刀头(1)时，先将动刀(12)的旋转支撑凸台(121)卡进动刀支架(14)的动刀支撑部(141)的柱体之间，然后将刀网(13)通过卡齿槽(132)卡持在旋转支撑凸台(121)上；进一步的，将上述动刀(12)、动刀支架(14)和刀网(13)组成的组合体从刀头本体(11)的容纳腔(112)的第二开口处插入到容纳腔(112)中并通过导向卡紧筋(112)对动刀支架(14)的底部平板进行卡紧，最后，将端盖(111)旋入在刀头本体(11)的下端部进行固定，即可完成组装。组装完后，刀网(13)的网面部(132)从容纳腔(112)的第一开口处露出，并且通过结构设计让刀头本体(11)的阻挡部(113)所围成的轮廓尺寸构造比刀网(13)的底部部分的尺寸构造小，所以使得阻挡部(113)可以阻挡住刀网(13)不会从容纳腔(112)的第一开口处中脱出。
进一步的，传动机构(3)为两段式杆体结构，分为第一杆体(31)和第二杆体(32)，其中，第一杆体(31)的一端具有包容腔(311)，包容腔(311)的侧壁上具有对称的两个固定孔；第二杆体(32)的一端具有T型头(321)，第二杆体(32)的T型头(321)放置在第一杆体(31)的包容腔(311)内，并且T型头(321)的两个头部卡持在包容腔(311)的两个固定孔上，固定孔的尺寸规格大于T型头的尺寸规格，使得第二杆体(32)和第一杆体(31)之间可以绕着两者的连接部位为支点进行偏离其统一轴心线的绕动，参考图7所示。此种结构的优势在于，第二杆体(32)和第一杆体(31)即使不在同一轴心线上，两者亦可实现对旋转动能的传递。本领域的普通技术人员也可以适当改进，在第一杆体(31)的一端设置包容腔，包容腔的腔型为球形状，第二杆体(32)的一端设置一个球形头，然后将第二杆体(32)的球形头放入到第一杆体(31)的包容腔中，使两者结合在一起的结构方式，亦属于本实用新型的保护范围。
进一步的，刀身(2)内设置有腔体，腔体在刀身(2)的上端面处具有开口，开口的轮廓尺寸与端盖(111)上的安装部(1112)的轮廓尺寸相匹配，刀身(2)内还设置有电机(21)，电机(21)固定在腔体内，电机(21)的输出轴上设置有与所述传动机构(2)匹配的连接杆(22)。
进一步的，刀身(2)的表面上还设置有触控按钮(23)，用于控制电机(21)的启动、停机和旋转模式。刀身(2)内还设置有电池和控制电路板，电池、控制电路板、触控按钮和电机(21)之间形成电连接。
当需要组装刀头(1)、刀身(2)和传动机构(3)时，取出上述组装好的刀头(1)，将传动机构(3)中的第二杆体(32)的一端从端盖(111)中的通过孔(1111)处穿过并连接到动刀(12)的旋转支撑凸台(121)上，然后将传动机构的(3)中的第一杆体(31)的一端从刀身(2)的上端面开口处穿过后连接到电机(21)输出轴上的连接杆(22)，最后将端盖(111)的下端部的安装部(1112)插入到刀身(2)在上端面的腔体开口处并进行固定。通过结构设计，使得端盖(111)的安装部(1112)插入到刀身(2)腔体开口处形成过盈紧配合。本领域的普通技术人员也可以通过技术改进，采用螺纹绞合的方式使端盖(111)和刀身(2)进行固定，此方式也属于本实用新型保护范围。
在使用本电动剃须刀时，刀网(13)的网面部(131)在人体脸部移动时，因为脸部轮廓的起伏和人手握住剃须刀施加的压力不同，脸部会对刀网(13)产品间断性的压力，此压力通过刀网(13)中的卡持槽(132)传递给动刀(12)的旋转支撑凸台(121)，并最终传递给弹性部件(142)，弹性部件(142)接收到压力时会进行压缩，当压力消失时会自动恢复，从而带动动刀(12)和刀网(13)的浮动。并且，由于传动机构(3)中第一杆体(31)和第二杆体(32)之间可以绕着两者的连接部位为支点进行偏离其统一轴心线的绕动，所以，在动刀(12)浮动时，连接动刀(21)的第二杆体(32)会跟着一起浮动，但是此浮动不会传递到第一杆体(31)上，所以不会影响电机(21)将旋转动能传输给动刀(12)。
结合图6所示，动刀(12)在以旋转支撑凸台(121)为运动支点，在电机(21)的带动下，做360度旋转运动或做圆弧往复式运动，做圆弧往复式运动时的振幅角度约为3度。由于刀网(13)的网面部(131)的弧度与所述动刀外周的弧度相同，动刀(12)柱面上的刀刃在旋转或往复式运动时与网面部(131)内侧面相贴并且运动方向与网面部(131)相切。
上述动刀(12)和刀网(13)浮动的结构设置，可以让使用者在剃须过程中不会太生硬，增加剃须舒适度。
以上所述实施例仅表达了本实用新型的实施方式，其描述较为具体与详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。
