Description

一种毛发剪 技术领域
[0001] 本发明涉及一种毛发剪, 属于美容美发工具技术领域。
背景技术
[0002] 剪刀是人们日常生活中常用的剪切工具。 常见的美容美发用的毛发剪, 结构如 图 1所示, 包括第一剪刀体 1、 第二剪刀体 2和将第一剪刀体 1和第二剪刀体 2可转 动地连接成一体的结合件 3, 第一剪刀体 1具有第一刃体部 11 (不动刃) 和第一 剪把 12, 第二剪刀体 2具有第二刃体部 21 (动刃) 和第二剪把 22。 其第一剪刀体 1与第二剪刀体 2结构和大小基本相同, 第一剪刀体 1与第二剪刀体 2在刀刃在刚 咬合吋 (此吋即将对位于刀刃之间的物体进行剪切) , 两个刃口之间形成的夹 角的角度为 70-80°之间。 在进行剪发吋, 由于毛发粘附有油脂, 第一刃体部 11 ( 不动刃) 与第二刃体部 21 (动刃) 在咬合并进行剪切毛发的过程中, 如图 2所示 , 毛发会向刀尖部分滑动, 从而导致剪切位置发生偏移, 从而无法做到对剪切 位置的精确控制。
[0003] 剪发吋, 毛发滑动是一个世界性的难题。 为了防止毛发发生滑动, 目前通常采 用的方案是将其中一个刀刃做出锯齿状 (刀刃上幵设凹槽) , 如中国专利文献 C M1312751A、 CN 203077312 U等, 然而锯齿状的刀刃使刀刃丧失了锋利度, 无 法很好地完成一些剪发中的挑剪、 滑剪等剪法。
技术问题

[0008] 优选地, 本发明的毛发剪, 所述第二刃体部的刀刃部分的宽度小于第一刃体部 的刀刃部分的宽度。
[0009] 优选地, 本发明的毛发剪, 所述第一剪刀体与所述第二剪刀体合拢吋, 以交点 A做剪刀中轴线的垂线, 位于第一刃体部部分的垂线的宽度 HI与位于第二刃体部 部分的垂线的宽度 H2之比为 3:2-15:11。
[0010] 优选地, 本发明的毛发剪, 所述第一剪刀体与第二剪刀体的宽度均向着刀尖方 向逐渐减小。
[0011] 优选地, 本发明的毛发剪, 所述第一刃体部和 /或所述第二刃体部的刀刃由靠 近所述结合件的直线段和远离所述结合件的弧线段构成。
[0012] 优选地, 本发明的毛发剪, 所述直线段的长度 L为 1.8至 2.5cm。
[0013] 优选地, 本发明的毛发剪, 所述第一刃体部和所述第二刃体部的刀刃由一段或 者多段弧线构成。
[0014] 优选地, 本发明的毛发剪, 所述弧线的曲率小于 0.05m -i。
[0015] 优选地, 本发明的毛发剪, 所述弧线的曲率向着刀尖方向逐渐增大。

发明的有益效果
有益效果
[0017] (1) 本申请的毛发剪, 第一刃体部和第二刃体部的刀刃在刚咬合吋, 以所述 第一刃体部和第二刃体部的刀刃的交点分别做所述第一刃体部和第二刃体部的 刀刃的切线, 两个切线的夹角为 35°-50°。 剪切吋, 剪刀会向被剪的毛发施加一 个向刀尖方向的分力 (沿刀刃的切线方向) 和垂直刀刃的分力 (垂直于刀刃的 切线方向) , 垂直刀刃的分力同吋会对毛发产生压力从而形成摩擦力, 当两个 切线的夹角为 35°-50°吋, 向刀尖方向的分力被摩擦力抵消, 在剪切毛发的过程 中, 毛发不会滑动, 从而使得操作者能够精确控制剪切位置, 实现精准剪切。
[0018] (2) 本申请的毛发剪, 第二剪刀体的宽度减小, 导致毛发剪重量减轻了减小 了约五分之一, 同吋由于第一刃体部和第二刃体部的刀刃在刚咬合吋角度减小 到 35°-50°, 操作者在用力剪发吋, 无名指和拇指操作角度变小, 用力也减小了 约三分之一, 从而降低操作者腱鞘炎 (职业病) 的发生的风险。
[0019] (3) 本申请的毛发剪, 仅改变第二剪刀体 (剪切刃) 的宽度, 第一剪刀体宽 度较大, 便于理发师通过第一剪刀体作为基准, 方便观察和对准剪发位置。
[0020] (4) 本申请的毛发剪, 曲率小于 0.05m -1的弧线吋更接近直线, 便于操作者使 用剪刀。

[0059] 上述实施例 1-6中, 第二剪刀体 2的宽度减小, 导致毛发剪重量减轻了减小了约 五分之一, 同吋由于第一刃体部 11和第二刃体部 21的刀刃在刚咬合吋角度减小 到 35°-50°, 操作者在用力剪发吋, 无名指和拇指操作角度变小, 用力也减小了 约三分之一, 从而降低操作者腱鞘炎 (职业病) 的发生的风险。
[0060] 同吋, 本申请的毛发剪, 仅改变第二剪刀体 2 (剪切刃) 的宽度, 第一剪刀体 1 宽度较大, 便于理发师通过第一剪刀体 1作为基准, 方便观察和对准剪发位置。
[0061] 曲率小于 0.05m 1的弧线吋更接近直线, 便于操作者使用剪刀。
[0062] 本申请的毛发剪可作为人类理发剪刀, 宠物美容用剪刀。
[0063] 对比实施例
[0064] 分别选用若干剪刀, 其中余部分与实施例 3的相同, 不同点在于第一刃体部 11 和第二刃体部 21的刀刃在刚咬合吋, 第一刃体部 11和第二刃体部 21的刀刃的交 点 A分别与第一刃体部 11和第二刃体部 21的刀刃的切线的夹角 ot。

Figure imgf000010_0001
[0065] 分别使用对比例 1-4的剪刀来剪人类头发, 对于实施例 1和 2的剪刀部分毛发会 进入第一刃体部 11和第二刃体部 21之间的间隙内 (头发与第一剪刀体 1和第二剪 刀体 2的平面平行) , 无法剪断部分头发。 对于对比实施例 3和 4, 剪切吋, 毛发 会向刀尖方向滑动, 角度越大滑动距离越长。
[0066] 通过上述对比实施例 1, 说明第一刃体部 11和第二刃体部 21的刀刃在刚咬合吋 , 第一刃体部 11和第二刃体部 21的刀刃的交点分别与第一刃体部 11和第二刃体 部 21的刀刃的切线角度过小吋, 毛发会进入第一刃体部 11和第二刃体部 21之间 的间隙内, 造成无法对毛发进行剪切, 而角度过大吋, 剪切吋, 毛发会向刀尖 方向滑动。
[0067] 本申请不得理解为仅包括上述实施例尺寸的剪刀, 剪刀每增大或者缩小 1寸, 相应宽度尺寸 HI和 H2增大 lmm。
[0068] 以上述依据本申请的理想实施例为启示, 通过上述的说明内容, 相关工作人员 完全可以在不偏离本项申请技术思想的范围内, 进行多样的变更以及修改。 本 项申请的技术性范围并不局限于说明书上的内容, 必须要根据权利要求范围来 确定其技术性范围。
