Abstract

一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时被一体埋设于该装配口的周缘。该刀头罩的金属网罩与塑料支撑架之间的连接牢固,结实耐用;由于金属网罩周边在塑料支撑架注塑时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。

Description

一种电动剃须刀的刀头罩
技术领域
本实用新型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
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,当网罩贴在皮肤上时,毛发由网罩的通孔伸入,被刀片切断。
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。
实用新型内容
本实用新型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采用点连接而容易造成金属网罩凹凸不平滑的缺点。
一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时被一体埋设于该装配口的周缘。
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。
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。
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时被一体埋设于该装配口的周缘。
由上述对本实用新型结构的描述可知,和现有技术相比,本实用新型具有如下优点:一,金属网罩与塑料支撑架之间的连接牢固,结实耐用;二,由于本实用新型刀头罩的金属网罩周边在塑料支撑架注塑时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。

实施例一
一种电动剃须刀的刀头罩,参照图1至图3,包括金属网罩1和塑料支撑架2,该塑料支撑架2设有一装配口20,该金属网罩1覆盖该装配口20。在电动剃须刀整体结构中,该刀头罩内设有刀片组,刀片组配合于金属网罩1下方,刀片组来回移动以将伸入金属网罩1的毛发切断,该刀头罩下方还设有一壳体,该壳体内设有驱动所述刀片组来回移动的驱动装置。本实用新型的重点在于刀头罩的结构,其余部分在此不详细说明。
该金属网罩1的周边在所述塑料支撑架2注塑成形时被一体埋设于该装配口20的周缘中。该金属网罩1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11和两平滑曲线12围成,所述塑料支撑架2的装配口20的形状与该金属网罩1周边的形状相适配。参照图2和图3,该塑料支撑架2装配口20的两曲线边的中部连设有一支撑条21,该支撑条21支撑于所述金属网罩1下方。
实施例二
参照图4、图5,包括金属网罩1和塑料支撑架2,该塑料支撑架2设有一装配口20,该金属网罩1覆盖该装配口20。在电动剃须刀整体结构中,该刀头罩内设有可旋转的刀片组,刀片组配合于金属网罩1下方,刀片组旋转以将伸入金属网罩1的毛发切断,该刀头罩下方还设有一壳体,该壳体内设有驱动所述刀片组旋转的驱动装置。本实用新型的重点在于刀头罩的结构,其余部分在此不详细说明。
参照图5,该刀头罩的金属网罩1包括一圆形的顶面11和由该顶面11的周边向下延伸的柱面12,该柱面12的下端向外延伸形成一凸环13,所述塑料支撑架2装配口20的形状也为圆形,所述凸环13在所述塑料支撑架2注塑成形时被一体埋设于该装配口20的周缘中。
上述仅为本实用新型的具体实施方式,但本实用新型的设计构思并不局限于此,凡利用此构思对本实用新型进行非实质性的改动,均应属于侵犯本实用新型保护范围的行为。
