Description

说明书 发明名称：电推剪刀头定刀副片及电推剪刀头定刀 技术领域
[0001] 本发明涉及理毛发用具， 提供一种电推剪刀头定刀副片及采用该电推剪刀头定 刀副片的电推剪刀头定刀。
背景技术
[0002] 电推剪是日常生活常用理毛发工具， 一般包括电推剪刀头和电推剪本体。 电推 剪刀头是电推剪的主体功能组件， 主要包括定刀、 动刀及其他辅件。 目前国内 外市场上的电推剪刀头多采用高碳钢作为定刀和动刀材料， 极少数价格较高的 电推剪刀头采用钨钢硬质合金材料或陶瓷材料， 且陶瓷材料目前只用作动刀材 料。 高碳钢硬度不高， 且质脆， 作为刀片材料耐磨性较差， 因此高碳钢定刀怕 摔， 还需要润滑油润滑， 高碳钢电推剪刀头一年需要磨 4-5次甚至更多次， 而专 业磨电推剪刀头的师傅很少， 需要较高的费用， 频繁更换也会带来较高的成本 。 陶瓷材料耐磨性好， 但缺点是脆度更大， 因此只适合厚度较小的定刀， 不适 合做厚度较大的定刀， 且不适合整体定刀均采用陶瓷材料。 钨钢具有硬度高、 耐磨、 强度和韧性较好、 耐热、 耐腐蚀等一系列优良性能， 可作为电推剪刀头 定刀的性能理想材料， 但钨钢价格高， 因此若整个刀头采用钨钢制作， 生产成 本高。
技术问题
[0003] 本发明是鉴于现有技术中存在的上述问题而做出的， 其目的是提供一种生产成 本低、 可更换的电推剪刀头定刀副片。
[0004] 本发明的另一目的是提供一种带有上述电推剪刀头定刀副片的电推剪刀头定刀 问题的解决方案
技术解决方案
[0005] 为实现上述目的， 本发明的第一技术方案的电推剪刀头定刀副片， 其特征在于 ， 该定刀副片的前端具有定刀刀齿， 该定刀副片上的与电推剪刀头的动刀接触 的一面的定刀刀齿后部设有凹槽， 该定刀刀齿的与电推剪刀头的动刀刀齿接触 的一面中间设置有内凹面。 通过在定刀副片的与电推剪刀头的动刀接触的一面 的定刀刀齿后部设置凹槽， 可以把定刀副片加工成具有较宽的宽度以保证安装 方便的同吋， 还能够确保将定刀副片的与动刀的接触面积加工成尽量小， 以使 得电推剪刀头的剪切能够更加顺利。
[0006] 本发明的第二技术方案的电推剪刀头定刀副片， 在第一技术方案的基础上， 其 特征在于， 所述内凹面内填充软质材料。

实施该发明的最佳实施例
本发明的最佳实施方式
[0044] 为使本发明的目的、 技术方案和优点更加清楚， 下面结合附图对本发明进行详 述。
[0045] 第一实施例
[0046] 如图 1所示， 本实施例的电推剪刀头定刀包括定刀主体 2和定刀副片 1。
[0047] 图 2为电推剪刀头定刀副片的示意图。
[0048] 图 3为电推剪刀头定刀的梳齿和定刀刀齿的与动刀相接触的一面的局部放大图
[0049] 定刀主体 2的前端具有凹形平台 21， 凹形平台 21的前端具有梳齿 22， 凹形平台 2 1上设置有第四固定孔 25。 梳齿 22用于梳理毛发， 梳齿 22的后部具有断面， 梳齿 22 (特别是长度较大的梳齿） 的前端侧缘设置有内凹防撞击缓冲区 26 (如图 3所 示） ， 当梳齿 22受到外力冲击吋， 梳齿 22自内凹防撞击缓冲区 26处折断或变形 ， 避免梳齿 22从根部折断或变形。
[0050] 定刀主体 2的后端设置有第二固定孔 23， 第二固定孔 23用于通过螺丝或卡扣件 将定刀主体 2固定于电推剪刀头的刀架上。
[0051] 定刀副片 1的前端具有定刀刀齿 12， 定刀副片 1上的与电推剪刀头的动刀接触的 一面的定刀刀齿 12的后部设有凹槽 11， 凹槽 11内设置有起固定作用的第一固定 孔 13。 定刀刀齿 12的前部为断面， 凹形平台 21的大小与定刀副片 1的大小吻合， 定刀刀齿 12的断面与梳齿 22的断面紧密配合设置。 定刀刀齿 12的断面与梳齿 22 的断面为相互适配的弧形或其他形状的断面， 避免毛发夹挂于定刀刀齿的断面 与梳齿的断面接触处。 如图 3所示， 定刀刀齿 12的与动刀刀齿接触的一面中间设 置有内凹面 14， 且定刀刀齿与动刀刀齿的接触面积自刀齿前端向刀齿根部逐渐 变小。 内凹面 14内填充软质材料， 避免毛发夹入内凹面 14内。
[0052] 采用螺丝、 铆钉、 卡扣件等固定件将定刀副片 1通过第一固定孔 13以及第四固 定孔 25固定于凹形平台 21内， 从而将定刀副片 1与定刀主体 2固定， 固定后， 定 刀刀齿 12的断面与梳齿 22的断面紧密贴合。
[0053] 当然， 凹形平台 21上和凹槽 11内也可以不设置第四固定孔 25和第一固定孔 13， 而仅通过粘接方式将定刀副片 1固定于凹形平台 21内， 从而完成定刀副片 1与定 刀主体的 2固定， 组成电推剪刀头定刀， 进而将电推剪刀头定刀通过第二固定孔 23固定在刀架上。
[0054] 定刀副片 1和定刀主体 2为分离式的结构， 这样定刀副片 1和定刀主体 2可采用不 同的材料， 定刀主体 2可采用廉价的塑料、 铝合金、 不锈钢等任何适用的材料， 定刀副片 1则采用高碳钢、 陶瓷、 钨钢等硬质耐磨材料， 从而减少刀片昂贵材料 的使用， 降低生产成本。 并且， 由于定刀副片 1可拆卸地固定于所述凹形平台 21 内， 当定刀副片 1一定程度磨损后， 只要更换定刀副片即可， 而不用更换整个定 刀， 同样当定刀主体 2损坏后可单独更换， 方便快捷， 延长电推剪刀头的使用寿 命。
[0055] 采用螺丝、 铆钉、 卡扣件等固定件通过固定孔或者采用粘接方式将分离的定刀 副片 1和定刀主体 2相互固定， 进而采用螺丝、 铆钉、 卡扣件等固定件将整体定 刀结构固定于电推剪刀头的刀架上， 从而提高电推剪使用吋的稳定性， 并方便 拆卸， 利于各部件的清洗与维护。
[0056] 此外， 在定刀副片 1的与定刀主体 2的凹形平台 21接触的一面， 可在定刀副片 1 的厚度方向上形成 1个或多个任意形状的凹陷部分， 或者可以在定刀主体 2的与 定刀副片 1接触的凹形平台 21上， 在定刀主体 2的厚度方向上形成 1个或多个任意 形状的凹陷部分， 再或者在定刀副片 1和所述凹形平台 21的相互接触的面上， 在 各自的厚度方向上分别形成 1个或多个任意形状的凹陷部分， 通过设置这些凹陷 部分可减小需要加工平整的定刀副片 1和凹形平台 21的接触面面积， 同吋能够节 省定刀副片和定刀主体的材料。 再或者直接在定刀副片 1和定刀主体 2的凹形平 台 21的相应部位形成镂空部分， 这些镂空部分可进一步减小需要加工平整的定 刀副片 1和凹形平台 21的接触面面积， 同吋能够节省定刀副片和定刀主体的材料
[0057] 第二实施例
[0058] 如图 4所示， 本实施例的电推剪刀头定刀包括定刀主体 2和定刀副片 1。
[0059] 图 5为如图 4所示的电推剪刀头定刀的侧剖面示意图。
[0060] 图 6为如图 4所示的电推剪刀头定刀副片的示意图。
[0061] 图 7为如图 4所示的电推剪刀头定刀的梳齿和定刀刀齿的与动刀相接触的一面的 局部放大图。
[0062] 定刀主体 2的前端具有梳齿 22， 梳齿 22用于梳理毛发， 梳齿 22 (特别是长度较 大的梳齿） 的前端侧缘设置有内凹防撞击缓冲区 （如图 7所示） ， 当梳齿 22受到 外力冲击吋， 梳齿 22自内凹防撞击缓冲区处折断或变形， 避免梳齿 22从根部折 断或变形。
[0063] 定刀副片 1采用陶瓷、 钨钢或高碳钢等硬质耐磨材料制成， 定刀副片 1上具有凹 槽 11， 凹槽 11内设置有起固定作用的第一固定孔 13。 定刀副片 1的前端具有定刀 刀齿 12， 定刀刀齿 12的与动刀刀齿接触的一面中间设置有内凹面 （如图 7所示） ， 且定刀刀齿与动刀刀齿的接触面积自刀齿前端向刀齿根部逐渐变小。 内凹面 内填充软质材料， 避免毛发夹入内凹面内。 需要注意的是， 本实施例的定刀刀 齿 12不同于第一实施例中的定刀刀齿， 本实施例的定刀刀齿 12的前部不具有断 面。
[0064] 定刀主体 2的后端设置有第二固定孔 23， 第二固定孔 23用于通过螺丝或卡扣件 将定刀主体 2固定于电推剪刀头的刀架上， 定刀刀齿 12与梳齿 22配合设置。 定刀 主体 2的与定刀副片 1上的第一固定孔 13相对应的位置设置第三固定孔 24， 采用 螺丝或卡扣件通过定刀主体 2上的第三固定孔 24以及定刀副片 1上的第一固定孔 1 3将定刀副片 1和定刀主体 2可拆卸地固定。 [0065] 采用螺丝、 铆钉、 卡扣件等固定件将定刀副片 1通过第一固定孔 13以及第三固 定孔 24固定于定刀主体 2上， 从而将定刀副片 1与定刀主体 2固定， 固定后， 定刀 刀齿 12与梳齿 22的紧密贴合。
[0066] 当然， 定刀主体 2上和凹槽 11内也可以不设置第三固定孔 24和第一固定孔 13， 而仅通过粘接方式将定刀副片 1固定于定刀主体 1上， 从而完成定刀副片 1与定刀 主体的 2固定， 组成电推剪刀头定刀， 进而将电推剪刀头定刀通过第二固定孔 23 固定在刀架上。
[0067] 此外， 在定刀副片 1的与定刀主体 2接触的一面， 可在定刀副片 1的厚度方向上 形成 1个或多个任意形状的凹陷部分， 或者可以在定刀主体 2的与定刀副片 1接触 的面上， 在定刀主体 2的厚度方向上形成 1个或多个任意形状的凹陷部分， 再或 者在定刀副片 1和所述定刀主体 2的相互接触的面上， 在各自的厚度方向上形成 1 个或多个任意形状的凹陷部分， 这些凹陷部分可减小需要加工平整的定刀副片 1 和定刀主体 2的接触面面积， 同吋能够节省定刀副片和定刀主体的材料。 再或者 直接在定刀副片 1和定刀主体 2的相应部位形成镂空部分， 这些镂空部分可进一 步减小需要加工平整的定刀副片 1和定刀主体 2的接触面面积， 同吋能够节省定 刀副片和定刀主体的材料。
[0068] <第一变形例 >
[0069] 对于第一实施例， 定刀副片 1与定刀主体 2的固定方式可作出如下变形：
[0070] 如图 8所示， 定刀副片 1的凹槽 11内设置方孔 15， 定刀主体 2的相应位置设置有 与定刀副片 1上的方孔 15相适配的凸起 27， 通过方孔 15与凸起 27的适配扣合作用 将定刀副片 1与定刀主体 2可拆卸地固定， 从而组成电推剪刀头定刀。
[0071] 当然对于第二实施例， 定刀副片 1与定刀主体 2的固定方式也可以做出相同构思 的变形。
[0072] <第二变形例 >
[0073] 对于第一实施例， 定刀副片 1与定刀主体 2的固定方式还可作出如下变形： [0074] 如图 9所示， 定刀副片 1的两侧边上分别形成内凹 16， 定刀主体 2两侧边上的相 应位置设置有与定刀副片 1两侧边上的内凹 16相适配的凸起 28， 通过内凹 16与凸 起 28的适配扣合作用将定刀副片 1与定刀主体 2可拆卸地固定， 从而组成电推剪 刀头定刀。
[0075] 当然对于第二实施例， 定刀副片 1与定刀主体 2的固定方式也可以做出相同构思 的变形。
[0076] 第三实施例
[0077] 如图 10电推剪刀头的分解示意图所示， 本实施例的电推剪刀头， 包括由定刀副 片 1及定刀主体 2组成的定刀、 动刀 3以及紧固连接件 （图中未示出） 。
[0078] 紧固连接件通过螺丝或螺钉、 扭簧以及弹簧压片可拆卸地连接固定定刀和动刀 3， 具体地， 采用螺丝或螺钉将紧固连接件的一端与定刀固定， 并采用扭簧及弹 簧压片通过压紧紧固连接件来压紧动刀 3， 从而将定刀和动刀 3连接固定。 定刀 为第一实施例中的定刀， 当然也可换为第二实施例或第一及第二变形例中的定 刀。 如图 11所示， 动刀刀齿 31的与定刀刀齿接触的一面中间设置有内凹面 32， 且动刀刀齿与定刀刀齿的接触面积自刀齿前端向刀齿根部逐渐变小。 内凹面 32 内填充软质材料， 避免毛发夹入内凹面 32内。 动刀刀齿 31与定刀刀齿 12交错紧 密贴合， 动刀 3可沿定刀的刀齿内沿线横向运动， 从而剪去动刀的刀齿与定刀的 刀齿之间的毛发。
[0079] 由于采用局部可拆卸更换的定刀， 因此， 整体电推剪刀头在降低生产成本的同 吋， 方便用户自己更换定刀副片、 定刀主体或动刀， 维修方便， 使用成本降低 。 同吋由于定刀和动刀的刀齿的相互接触面均为内凹面设计， 动刀刀齿与定刀 刀齿的接触面积自刀齿前端向刀齿根部逐渐减小， 因此动刀滑动过程中动刀刀 齿与定刀刀齿之间产生自磨作用， 使得动刀和定刀副片的使用寿命延长， 从而 延长电推剪刀头的使用寿命。
[0080] 以上所述的实施方式仅用于具体说明本发明的精神， 本发明的保护范围并不局 限于此， 对于本技术领域的技术人员来说， 当然可根据本说明书中所公幵的技 术内容， 通过变更、 置换或变型的方式轻易做出其它的实施方式， 这些其它的 实施方式都应涵盖在本发明的保护范围之内。
