Description

一种剃须刀头机构
技术领域
本发明涉及剃须刀技术领域， 特别涉及一种采用浮动刀架座结构的剃须 刀头机构。 背景技术
剃须刀为男士必备之日常清洁用具。 目前， 在剃须刀中， 浮动刀架座常用 品字型分块刚体式浮动刀架座，浮动刀架座可同时相对于相应的外切刀及相对 于托架作枢轴转动。
图 3、 图 4和图 5所示， 现有技术的剃须刀头机构为： 两个或三个圆形的 旋转刀片组件从下方以止口结构分别配置在浮动刀架座 1中央的圆孔 la中， 浮动刀架座 1呈指甲状， 外侧为圆弧状， 内侧为直线平口或 120度的夹角， 两 个或三个浮动刀架座 1相互以直线平口对接， 或者以 120度的夹角相拼对接， 各个浮动刀架座 1的两边分别伸出一个转头 lb，以转动方式与剃须刀头壳相应 形状圆弧口的相应位置连接， 各个浮动刀架座 1可以绕转头 lb作上下略微的 翘动， 在剃须时， 各个浮动刀架座 1可以贴合脸颊作仿形翘动。 使用这种剃须 刀头机构， 可使剃须时作用在外切刀上的压力得到更有效的控制， 但还存在以 下问题： 1、 由于浮动刀架座 1为分体式的， 两个或三个浮动刀架座 1相互以直线 平口对接， 或者以 120度的夹角相拼对接， 用柔性材质来制作就可能会让多个 浮动刀架座 1贴合脸颊作仿形翘动时彼此脱离，故该结构与面部皮肤接触的浮 动刀架座 1采用硬的 ABS或其他的材质， 与面部皮肤接触会有疼痛感；
2、 现有技术的浮动刀架座 1采用硬胶搭接实现连动， 浮动件贴面会夹胡 须， 夹胡须拉伤皮肤； 也影响浮动刀架座正常工作；
3、 现有技术的多个浮动刀架座 1贴合脸颊作仿形翘动时， 浮动刀架座 1 之间会产生缝隙， 剃须了的胡须会夹在浮动刀架座 1之间。 同时分体式的浮动 刀架座 1不易清洁胡须， 需要逐一拆卸各个浮动刀架座 1进行清理，特别是对 行动迟缓的老年使用者特别不方便；
4、 现有技术的的浮动刀架座 1整体加工， 装配要求高， 制造成本也高。 发明内容
本发明要解决的技术问题是提供一种剃须刀头机构，该剃须刀头机构在剃 须时能够使浮动刀架座随面部轮廓的变化与皮肤保持紧贴面形的柔弹性面接 触， 从而使接触压力得到更好的调节和控制， 提高剃须时的安全度和舒适度。
为解决上述技术问题， 一种剃须刀头机构， 包括剃须刀头壳和设置在剃须 刀头壳内的浮动刀架座；两个或三个圆形的旋转刀片组件从下方以止口结构分 别配置在浮动刀架座中央的圆孔中； 其特征在于： 所述浮动刀架座由设置在内 部的硬胶材料和覆盖在外部的软胶材料制成， 呈指甲状， 外侧为圆弧状， 内侧 为直线平口或 120度的夹角；两个或三个所述浮动刀架座相互以直线平口或者 以 120度的夹角通过长条状薄软胶层相连接， 且长条状薄软胶层的厚度为 0. 05-0. 15mm;所述两个或三个所述浮动刀架座和长条状薄软胶层之间形成 I型 凹槽或 Y型凹槽；各个浮动刀架座的两边分别开设一个凹槽， 以转动方式与剃 须刀头壳相应形状转头的相应位置连接，各个浮动刀架座可以绕转头作上下略 微的翘动， 在剃须时， 各个浮动刀架座可以贴合脸颊作仿形翘动。
更进一步的，所述浮动刀架座覆盖在外部的软胶材料和长条状薄软胶层均 由橡胶材料制成，且相邻两浮动刀架座覆盖在外部的软胶材料和与其连接的长 条状薄软胶层一次注塑而成。
更进一步的，所述浮动刀架座覆盖在外部的软胶材料和长条状薄软胶层均 由 TPE材料制成,且相邻两浮动刀架座覆盖在外部的软胶材料和与其连接的长 条状薄软胶层一次注塑而成。
更进一步的， 所述长条状薄软胶层由 PP材料制成。
更进一步的，所述旋转刀片组件包括有一个定刀和一个相对所述定刀贴面 旋转的动刀， 所述的定刀上至少有一个毛发入口。
与现有技术相比， 本发明的优点是：
1、 浮动刀架座为柔弹性整体结构， 当浮动刀架座与皮肤接触时， 材料本 身的弹性能够将皮肤接触压力比较均匀地分布在浮动刀架座的各个部件，增加 剃须时的舒适感；
2、 浮动刀架座正面无凹槽， 当浮动刀架座在皮肤的压力下下凹时， 不会 夹持胡须， 消除了已有技术存在的安全隐患；
3、 由于浮动刀架座正面无凹槽， 非常容易清洁， 而不会像已有技术因凹 槽不易清洁产生卫生隐患；当需要清洁时，可以整体拆卸浮动刀架座进行清洁， 省时省力， 特别是方便了行动迟缓的老年使用者；
4、整体式浮动刀架座结构简单、 安装便捷， 容易加工， 且装配要求不高， 制造成本低廉。 附图说明
