Description

剃须装置
本发明涉及剃须装置，具体地说，涉及湿法剃须的剃须装置。
一种湿法剃须的装置至少含有一个刀片机构和一个与使用者邻近刀片的皮肤相贴合的表面。一般说来，剃须装置含有一前贴合皮肤面(刀刃机构刃口的前面)和一后贴合皮肤面(刀刃机构的后面)。前贴合皮肤面可称为保护面而后贴合皮肤面则可称为外罩面。贴合皮肤面与刃口一起联合工作，并且具有一种或多种功能，例如：限定剃须装置的几何形状，拉紧要剃须部位的皮肤，和/或在剃须过程中将剃须辅助材料转移到皮肤表面上。剃须装置可以是一种可与剃刀手柄相连或从手柄上卸下来的一次使用的刀架；也可以是一种与手柄做成整体的结构，结果，这种结构在刀刃变钝时，与整个剃刀作为一个整体扔掉。
本发明的目的就是要提供一种既能拉紧剃须部分皮肤又能将剃须辅助液转移到皮肤面上的剃须刀架。
本发明提供一种湿式剃须装置，该剃须装置包括一刀架，该刀架在其前部有一护面机构，一后部，由上述刀架的护面之后和上述刀架后部之前所支承的刀刃机构，上述刀刃机构有至少一个沿着上述刀架长度延伸的刃口和一个在上述后部支承的剃须辅助件，其特征在于剃须辅助件沿后部呈纵向延伸且位于一沿其纵向延伸的间隙内，其中，上述剃须辅助件有一与皮肤面贴合能流出剃须辅助液的头部，一个上述间隙内的窄颈区以及一个对着上述流出剃须辅助液的头部且在窄颈区侧的夹持部分，上述夹持部分有比上述间隙宽度更大的尺寸而上述流出剃须辅助液的头部截面积有至少二倍于上述夹持部分，其中上述剃须辅助件还包括一延伸部分，上述延伸部分沿穿过上述窄颈区和上述夹持部分第一轴线的宽度增大，上述头部沿着垂直上述第一轴线的轴尺寸为上述夹持部分最宽部位的两倍多。
在最佳实施例中，剃须辅助件还含有一个延伸部分，沿上述第一轴73的长度大于上述夹持部分沿一垂直于上述第一轴73的轴的最大部位的尺寸，而头部沿垂直于上述第一轴73的轴的横向尺寸为上述夹持部分最宽部位的三倍多。
在某些特殊的实施例中，剃须装置中上述活动的保护机构含有一个金属片上述整体的导向部分是上述金属片的凸出部分，上述刀架中的上述导向机构含有相对的沟槽，上述的凸出部分就放在该沟槽中，以便引导上述保护机构沿预定的路线移动。在上述刀架上，与上述刀刃机构的刃口相邻。上述刀刃机构安装成能相对于刀架作来回移动。
剃须辅助件是一种定向挤压件，它含有一种由疏水的聚合物材料和可溶于水的聚合物材料组成的混合物，该水溶性的聚合物材料能形成一种水基润滑剂。该剃须装置还含有第二刀刃机构，它被安装在刀架上，可相对于上述刀架来回移动；上述偏压机构含有整体的弹簧片，它对能上述的保护机构和上述的刀刃机构施加弹性的偏压。
本发明的其他特征和优点在下列结构附图对具体实施例的说明中便会明白。附图中：
图1为本发明剃须装置的透视图。
图2为图1的剃须装置沿图1中2-2线的剖视图。
图3为刀架和装在图1剃须装置中的剃须辅助件沿与图2相同的2-2线的分解剖视图。
图1和图2所示的剃须装置是一种如Jacobson的美国专利4,586,255中所公开的同类型剃须装置(该专利所公开的内容明确纳入本专利作为参考)。刀盒10的宽度约8毫米，高约4毫米，长约4厘米，它含有由聚合物材料模压而成的刀架12，刀架的两端14，16与前、后部分18，20互相连接。如图2和图3所示，在每一端部的前部分18的后面，设有槽22，24，26，在每一槽中分别设有一对加偏压的弹簧片28，30，32。活动的金属片保护件34具有约0.5毫米宽的保护面36和进入沟槽22的凸出部分，使其定位于前部分18的前表面38之后约2毫米处，活动的前刀片40带有进入相对沟槽24的导向部分，使它的刃口42位于刀架的前部分18的前表面38之后约2.7毫米处。后刀片44进入沟槽26中，故其刃口46位于前表面38之后约4.3毫米处。剃须辅助件50由后框架部分20支承。保护件34和两个刀片40，44由偏压弹簧片28，30，32向上顶到保护夹52，54上，分别与表面70对齐。刀盒10还含有附属的延伸部分56，58它们各具有一拱形的导轨面，以枢轴连接的方式与刀柄(未示出)相接合。
在后框架部分20上设置有由弯曲底面62形成的凹槽60(弯曲面的半径约为0.4毫米，圆心则位于上表面70之下约2.5毫米处)和凸台64，66，凸台64，66之间形成了一约0.6毫米宽的间隙68。
剃须辅助件50插入到凹槽60中，它是由不溶于水的基体材料(聚苯乙烯)和可溶于水的聚合物剃须辅助材料(聚环氧乙烷)的混合物挤压而成的。剃削辅助件50的长度约3厘米，厚度约0.6毫米，其头部72的外表面74为一半径约4毫米、弧长约2.34毫米的拱形表面。头部的延伸部分76由宽度约为0.8毫米的头部72向下逐渐变窄而形成宽约0.5毫米的窄颈区78，而圆柱形的卡钮80，其直径约为0.7毫米。剃须辅助件50借助后框架的凸台64，66与其窄颈区76的嵌合机械地夹持在凹槽60中，如图2所示。在这一位置下，贴紧使用者皮肤的剃须辅助件50头部72之前表面82在后刀片40的刃口42后面稍为离开2毫米以内，而其后表面84则延伸稍为超过后框架部分20的后表面86并复盖在后框架部分20的支承唇88，如图2所示。
活动保护件34的前表面位于刀盒10的前表面38之后约1.5毫米处，前刀片40的刃口42离刀盒10的前表面38约2.7毫米；后刀片44的刃口46离刀盒10前表面38约4.3毫米；剃须辅助件50的前缘82离刀盒10前表面38约5.9毫米，而剃须辅助件50的后缘84则延伸超过刀盒后主表面86约0.1毫米离开前表面38约8.1毫米)。因此，剃须辅助件的贴合皮肤表面的宽度约等于刀盒总宽度的25％以上，当它固定在其位置时，不会妨碍保护件34和刀片40或44的来回移动。剃须辅助件50由机械方法可靠地固定，不需使用任何粘接材料。剃须辅助件的形状是这样的，其头部72占去整个体积的一半以上，该头部72的横截面积约等于1.3平方毫米，圆柱形的卡钮80的横截面积约为0.4平方毫米，锥形的延伸部分76的横截面积约为0.6平方毫米。这种形状增加了转移面积和剃须辅助材料的体积，并且提供了一种可用机械方法牢固地固定在刀架12上的坚固的剃须辅助件50。
剃须辅助件50在带锥形的延伸部分76的头部72上具有较大的贴合皮肤的表面74，因此可促进可溶解的聚环氧乙烷剃须辅助材料从辅助件50的基体中转移到皮肤上。而且，剃须辅助件50具有加强的横截面形状和体积较小的牢固的圆柱体80，故促进了与剃须辅助件50外形有关的水溶性剃须辅助材料的析出。
使用时，将刀盒10固定到手柄上便可剃须。剃须时，当刀盒10沿着使用者的皮肤移动时，活动的保护件34和刀片40，44被弹簧片28，30，32的偏压着彼此独立地移动，与此同时，剃须辅助材料则从插入的剃须辅助件50中流出来。在每一剃须行程中，刀盒10作为一个整体绕手柄转动，紧贴要剃须的皮肤表面的轮廓。
