Description

说明书 一种电动剃须刀的刀头罩
技术领域
[1] 本发明涉及电动剃须刀结构， 具体地说是指一种电动剃须刀的刀头罩。
背景技术
[2] 电动剃须刀的基本原理是在一网罩下方设置左右摆动或旋转的刀片组， 当网罩 贴在皮肤上吋， 毛发由网罩的通孔伸入， 被刀片切断。
[3] 电动剃须刀的刀头罩通常包括金属网罩和塑料支撑架， 该金属网罩上分布有众 多小孔而形成网状， 并且该金属网罩弯曲成一半圆柱面状， 塑料支撑架具有与 该金属网罩形状相适配的开口， 金属网罩的周边与塑料支撑架的开口周缘定位 连接。 现有技术中， 金属网罩的周边与塑料支撑架的开口周缘之间通常是通过 若干设于塑料支撑架上的凸点和若干设于金属网罩周边的定位孔互相配合来实 现， 可见， 金属网罩的周边与塑料支撑架的开口周缘之间是点连接， 若凸点或 定位孔的距离稍有偏差， 则会使金属网罩扭曲而凹凸不平滑， 影响与刀片组的 配合。
发明内容
[4] 本发明提供一种电动剃须刀的刀头罩， 其主要目的在于克服刀头罩的金属网罩 周边与塑料支撑架开口周缘之间釆用点连接而容易造成金属网罩凹凸不平滑的 缺点。
[5] —种电动剃须刀的刀头罩， 包括金属网罩和塑料支撑架， 该塑料支撑架设有一 装配口， 所述金属网罩覆盖该装配口， 所述金属网罩的周边在所述塑料支撑架 注塑成形吋被一体埋设于该装配口的周缘。
[6] 前述一种电动剃须刀的刀头罩， 其金属网罩的形状为横断面为平滑曲线的柱面
， 其周边由两互相平行的直线和两平滑曲线围成， 所述塑料支撑架的装配口的 形状与该金属网罩周边的形状相适配。
[7] 进一步地， 所述塑料支撑架装配口的两曲线边的中部连设有一支撑条， 该支撑 条支撑于所述金属网罩下方。 [8] 前述一种电动剃须刀的刀头罩， 其金属网罩包括一圆形的顶面和由该顶面的周 边向下延伸的柱面， 该柱面的下端向外延伸形成一凸环， 所述塑料支撑架装配 口的形状也为圆形， 所述凸环在所述塑料支撑架注塑成形吋被一体埋设于该装 配口的周缘。
[9] 由上述对本发明结构的描述可知， 和现有技术相比， 本发明具有如下优点： 一
， 金属网罩与塑料支撑架之间的连接牢固， 结实耐用； 二， 由于本发明刀头罩 的金属网罩周边在塑料支撑架注塑吋就一体埋设于装配口周缘， 也就是说， 金 属网罩周边与塑料支撑架开口周缘之间的连接是平滑的线连接， 不会使金属网 罩扭曲变形； 三， 在金属网罩的下方设有支撑条可对软性的金属网罩起支撑作 用， 防止金属网罩凹陷变形。
