Description

说明书 电动剃须刀的刀头装置
技术领域
[1] 本发明涉及电动剃须刀的结构， 具体地说是指电动剃须刀的刀头装置。
背景技术
[2] 电动剃须刀通常包括主体和刀头装置， 刀头装置包括刀头罩和设于刀头罩内的 刀片组， 刀头罩包括一塑料支撑架和设于该塑料支撑上的金属网罩， 刀片组位 于金属网罩下方， 当毛发进入金属网罩内吋， 二者配合可将毛发切断。 根据刀 片组运动方式的不同， 可分为旋转式电动剃须刀和左右摆动式剃须刀。
[3] 左右摆动式剃须刀的金属网罩弯曲成一半圆柱面状， 其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 。 刀片组位于该半圆柱面状的金属网罩下方， 工作吋左右摆动。 该刀片组中的 各刀片的刀刃为半圆形， 与半圆柱面状的金属网罩的横截面相适配， 因此， 刀 片与刀片之间的空隙为半圆形， 当毛发进入该空隙吋， 容易在该空隙内滑动， 不利于切割。
[4] 发明内容
[5] 本发明提供一种电动剃须刀的刀头装置， 其主要目的在于克服现有左右摆动式 电动剃须刀的刀片与刀片之间的空隙为半圆形、 缝隙过长， 因而不利于切割毛 发的缺点。
[6] 本发明釆用如下技术方案： 电动剃须刀的刀头装置， 包括刀头罩和刀片组， 该 刀头罩包括一塑料支撑架和设于塑料支撑架上的金属网罩， 该金属网罩为一半 柱面形， 其横断面为一圆滑曲线， 刀片组可移动地设于该金属网罩下方， 该刀 片组各刀片的刀刃的形状为与该金属网罩相适配的圆滑曲线形， 所述各刀片刀 刃的中部设有一凹下的缺口， 各缺口共同组成一凹槽， 所述塑料支撑架上设有 一与该凹槽相适配的分隔条。
[7] 前述电动剃须刀的刀头装置， 其刀片组的各刀片设于一刀片支架上。
[8] 所述塑料支撑架设有一装配口， 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。
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： 通 过在刀片的刀刃上设置缺口， 并有缺口中设置分隔条， 使两刀片之间的缝隙分 分隔为两部分， 缩短了该缝隙的长度， 降低毛发在该缝隙中滑动的可能性， 有 利于毛发被切断。 同吋本发明金属网罩的周边在所述塑料支撑架注塑成形吋可 以一体埋设于该装配口的周缘中， 使用金属网罩与塑料支撑架之间的连接牢固 ， 更结实耐用。
附图说明
图 1为本发明实施例 1的立体结构示意图；
图 2为图 1中 A-A向剖视图；
图 3为图 2去除部分金属网罩示意图；
图 4为图 1中 B-B向剖视图；
图 5为本发明实施例 2的横向剖视图。
具体实施方式
下面参照附图说明本发明的具体实施方式。
实施例 1、 电动剃须刀的刀头装置， 参照图 1至图 4， 包括刀头罩和刀片组， 该 刀头罩包括一塑料支撑架 2和设于塑料支撑架 2上的金属网罩 1， 该金属网罩 1为 一半柱面形， 其横断面为一圆滑曲线， 其轮廓由两平行的直线边 11和两圆滑曲 线边 12组成， 塑料支撑架 2上设有与其形状相适配的开口 20， 该金属网罩 1对应 装配于该开口 20上。
所述刀片组由多个刀片 3组设于一刀片支架 31上而构成， 该刀片组可移动地设 于该金属网罩 1下方。 该刀片组各刀片 3的刀刃的形状为与该金属网罩 1相适配的 圆滑曲线形， 所述各刀片 3刀刃的中部设有一凹下的缺口 30， 各缺口 30共同组成 一凹槽， 所述塑料支撑架 2上设有一与该凹槽相适配的分隔条 21。 分隔条 21其剖 面为半圆形， 相应的各刀片 3刀刃的中部设有一凹下的缺口 30也为半圆形缺口。 实施例 2、 参照图 5与实施例 1不同之处在于： 金属网罩 1与塑料支撑架 2连接方 式： 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， 该金属网罩 1 的周边在所述塑料支撑架 2注塑成形吋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半柱面形， 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。 该塑料支撑架 2装配口 20的两曲线边的中部连设有一分隔条 21， 该分隔条 21支撑于所述金属网罩 1下方。
[19] 所述刀片组由多个刀片 3组设于一刀片支架 31上而构成， 该刀片组可移动地设 于该金属网罩 1下方。 该刀片组各刀片 3的刀刃的形状为与该金属网罩 1相适配的 圆滑曲线形， 所述各刀片 3刀刃的中部设有一凹下的缺口 30， 各缺口 30共同组成 一凹槽， 所述塑料支撑架 2上的分隔条 21的剖面形状与凹槽的形状相适配。
[20] 由此可见， 原来两刀片 3之间的较长缝隙被分隔为两个较小的缝隙， 实验证明 ， 这种结构可降低毛发在该缝隙中滑动的可能性， 有利于毛发被切断。
[21] 上述仅为本发明的具体实施方式， 但本发明的设计构思并不局限于此， 凡利用 此构思对本发明进行非实质性的改动， 均应属于侵犯本发明保护范围的行为。 工业实用性
[22] 本发明电动剃须刀的刀头装置， 通过在刀片的刀刃上设置缺口， 并有缺口中设 置分隔条， 使两刀片之间的缝隙分分隔为两部分， 缩短了该缝隙的长度， 降低 毛发在该缝隙中滑动的可能性， 有利于毛发被切断， 使用效果好， 具有良好的 工业实用性。
