背景技术
[0002] 旋转式剌须刀的刀头组件具中一般有一个或多个切削单元， 每个切削单元还有 一个或多个切削单元公共一个贴面托架， 一个或多个切削单元以及一个或多个 贴面托架共同构成了皮肤接触面。 现有的贴面托架大多为工程塑料制成。 贴面 托架中的皮肤接触面也就包含了大量的塑料表面。 由于工程塑料客观存在的属 性， 导致当剌须时皮肤与塑料表面接触时会有卡涩不顺畅的感觉， 而且还会造 成皮肤发红等现象， 严重影响了剌须体验。 另外， 在剌须刀工作时切削单元中 刀片之间的高速相对旋转并摩擦， 使得切削单元快速产生温度升高的现象， 当 皮肤与切削单元接触时， 这种高温会导致皮肤产生不适。
[0003] 中国专利 （公开号为 CN203831434U） 公开了一种冰爽旋转头剌须刀， 其通过 设置散热元件、 热电偶和冷却元件的组合实现散热， 将热电偶与剌须刀内部的 电源机构连接， 冷却元件通过热电偶与散热元件连接， 冷却元件露出至外刀片 周围， 利用冷却元件露出至外刀片的部分结构与皮肤接触， 再通过热电偶传递 热量至散热元件， 最后通过散热元件将热量散发到剌须刀外部。 然而该种技术 方案只是理想的认为冷却元件中的热量会通过热电偶传递至散热元件散发。 但 实际上， 由于热电偶与电源机构连接， 热电偶工作时会产生一定的热量， 而散 热元件和冷却元件均与热电偶连接， 那么热电偶产生的部分热量反而会传递至 冷却元件， 导致热量直接传递至皮肤， 特别地， 当剌须刀使用时间较长时， 该 部分热量会更加明显地导致皮肤产生热感， 降低使用者在剌须时的舒适感。 并 且， 该种结构的剌须刀因为增加热电偶， 也导致其供电电量大， 进而导致产品 的使用时间大幅度减少。

[0029] 实施例一。
[0030] 如图 1~3所示， 本申请实施例提供的一种切削单元， 其可以适用于例如剌须装 置或者类似于剌须装置等的个人护理用品上。 并且， 本实施例的切削单元主要 是安装在剌须装置的刀头组件上。
[0031] 具体地， 切削单元包括安装架 10和外刀片 20, 切削单元在实际安装或者组装过 程中， 视情况需要增加与外刀片 20配合的内刀片 （图未示） 。 安装架 10设有贯 通其上下两端的刀片腔 11， 刀片腔 11的设置用于供外刀片 20的安装和支撑， 并 且也提供了外刀片 20的活动空间。 外刀片 20安装于刀片腔 11中并外露出至安装 架 10的上端， 外刀片 20—般通过间隙配合的方式安装在刀片腔 11中， 并且， 夕卜 刀片 20外露出至安装架 10的上端的部分用于与人体的皮肤接触以此实现剌须工 作。 进一步地， 切削单元还包括金属散热部件 30, 金属散热部件 30设于安装架 1 0上， 且金属散热部件 30至少部分环绕于外刀片 20的周侧以用于与人体皮肤接触 并降低人体皮肤的热感度， 即金属散热部件 30可以半包围或者全包围地环绕设 置在外刀片 20的周侧。
[0032] 本申请实施例的切削单元， 由于在安装架 10上设置有金属散热部件 30, 并且该 金属散热部件 30至少部分环绕于外刀片 20的周侧， 由此使得皮肤接触安装架 10 的面积得以减小， 皮肤能够实现与该金属散热部件 30接触， 通过此金属散热部 件 30较高的导热率， 即通常情况下金属散热部件 30的温度与室温基本相同， 而 人的体温通常是高于室温的， 所以当皮肤接触此金属散热部件 30时会有凉爽的 感觉。 同时由于该金属散热部件 30不再与其他产生会热量的电动部件接触， 例 如， 本实施例中的切削单元不再需要使用热电偶， 彻底避免热电偶自身产生的 热量传递至金属散热部件 30上， 如此可以确保当因为外刀片 20工作而产生高温 会给人的皮肤带来不适的感觉时， 该金属散热部件 30可以有效地吸收皮肤上的 热量并进行散发， 进而使得皮肤得以降温， 大大提升使用的舒适感。
[0033] 并且， 本实施例的切削单元应用于剌须装置上时， 不需要多增加电量的消耗， 确保剌须装置在有限的电量内能够使用更长的时间。
[0034] 优选地， 金属散热部件 30采用铝、 铁或者不锈钢制成。 也就是说， 通过铝材质 或者铁材质或者不锈钢材质制成成型金属散热部件 30, 通过上述材质制造出的 金属散热部件 30均能够实现与皮肤接触时可以降低人体皮肤的热感度， 通过吸 收皮肤中的热量并进行散发， 提升使用的舒适感。
[0035] 当然， 在其他实施例， 也可以采用其他金属材质制造金属散热部件 30, 例如铝 合金等， 在此不再进行一一列举。
[0036] 进一步地， 金属散热部件 30根据实际需求， 可以采用压铸、 锻造等的方式制造 成型。
[0037] 本实施例中， 如图 3和图 6所示， 安装架 10的上端面位于外刀片 20的周侧设有安 装槽 12, 安装槽 12位于安装架 10上开设的刀片腔 11上方开口的周侧， 即安装槽 1 2与刀片腔 11上方开口之间具有一定的间距， 该间距根据生产要求设定即可， 金 属散热部件 30的部分嵌设于安装槽 12内， 金属散热部件 30嵌设于安装槽 12内保 持稳定即可， 安装槽 12的尺寸根据实际需求调整， 只要保证能够使得嵌设安装 后的金属散热部件 30稳定性良好， 使用时或者经过长期的使用不易脱落。 具体 地， 金属散热部件 30的下端以及部分靠近其下端的结构嵌设在安装槽 12内， 这 样可以确保金属散热部件 30的上端以及部分靠近其上端的结构外露出至安装架 1 0的上端， 如此使得完成安装后的金属散热部件 30具有能够与皮肤有效结构的部 位。 同时， 通过嵌设的方式可以有效提升金属散热部件 30安装后的稳定性。
[0038] 进一步地， 安装架 10可以采用塑胶材料制成， 金属散热部件 30可以通过在注塑 成型安装架 10时， 一体成型注塑在安装架 10上， 以此使得嵌设在安装架 10成型 的安装槽 12内。 也可以先注塑成型出具有安装槽 12的安装架 10, 后期通过过盈 配合的方式将金属散热部件 30嵌入安装槽 12内。
[0039] 本实施例中， 如图 2所示， 安装槽 12的为盲槽结构， 且安装槽 12的槽底壁与安 装架 10的下端具有间距 H， 安装槽 12的深度小于安装架 10的上端至其下端的高度 。 具体地， 盲槽结构的安装槽 12可以避免安装槽 12贯穿安装架 10的上下两端， 通过在底部封堵的安装槽 12结构可以避免金属散热部件 30与其他会产生热量的 电动部件 （例如热电偶） 接触导致非皮肤上的热量传递至金属散热部件 30上引 其金属散热部件 30过热而无法吸收皮肤上的热量， 进而影响到金属散热部件 30 为皮肤的降温效果。
[0040] 进一步地， 如图 2和图 5~6所示， 安装槽 12的形状与金属散热部件 30的形状相适 配。 并且， 安装槽 12的宽度 （即安装槽 12内相对的两内侧壁之间的间距） 略大 于金属散热部件 30的宽度 （即金属散热部件 30外相对的两外侧壁之间的间距）
， 这样可以使得金属散热部件 30嵌设在安装槽 12内上与安装槽 12之间形成过盈 的配合， 即金属散热部件 30与安装槽 12形成紧配， 大大提升金属散热部件 30嵌 设在安装槽 12内的稳定性和可靠性。 其中， 安装槽 12的宽度略大于金属散热部 件 30的宽度中的“略大于”为金属散热部件 30能够嵌设入安装槽 12内， 并且又不会 破坏安装槽 12的结构为前提， 具体大于的尺寸根据需求设定， 例如安装槽 12的 宽度比金属散热部件 30的宽度大 0.1mm以上或者以下均可。
[0041] 另外， 安装槽 12的形状与金属散热部件 30的形状相适配， 即当金属散热部件 30 的整体形状为规则时， 那么安装槽 12的整体形状也为规则的； 当金属散热部件 3 0的整体形成为不规则时， 那么安装槽 12的整体形状也为不规则的， 如此确保安 装槽 12能够与金属散热部件 30形成形状上的相适配， 便于金属散热部件 30嵌设 安装在安装槽 12内。
[0042] 当然， 安装槽 12的宽度可以相等于金属散热部件 30的宽度， 即安装槽 12的宽度 与金属散热部件 30的宽度存在的差值为零或者可以忽略不计。 如此设计也可以 使得金属散热部件 30能够稳定且可靠地嵌设安装在安装槽 12内。 例如， 当在注 塑成型安装架 10时， 将金属散热部件 30置于模具中与安装架 10—体成型， 此时 的金属散热部件 30嵌设在安装架 10上形成的安装槽 12内， 并且此时的安装槽 12 的宽度与金属散热部件 30的宽度是相同或者差值几乎为零。
[0043] 本实施例中， 如图 2和图 5所示， 金属散热部件 30包括位于其上端的冷却面 31， 冷却面 31用于与人体的皮肤接触， 并且该冷却面 31呈弧形状。 呈弧形状的冷却 面 31的设置， 一方面是增大金属散热部件 30与皮肤的接触面积， 减少安装架 10 的上端面与皮肤接触的面积， 这样来提升金属散热部件 30对皮肤的吸热效果， 从而提升对皮肤的散热效果， 进而能够加快对皮肤的散热效率； 另一方面该弧 形状的冷却面 31可以提升与皮肤接触的舒适感， 即弧形状的冷却面 31更加光滑 ， 其能够有效地降低剌须时皮肤与接触面接触时的卡涩不顺畅的感觉， 进而提 升使用时的舒适感。
[0044] 优选地， 如图 2和图 5所示， 金属散热部件 30上端的冷却面 31的通过在金属散热 机构的相对的两外侧壁与上端面之间的夹角处进行倒圆角设计形成。 进一步地 ， 倒圆角与金属散热部件 30的上端面之间平滑无棱角过渡。
[0045] 更进一步地， 金属散热部件 30即可以是实心结构也可以是空心结构， 例如， 整 体结构的截面可以为“n”字形状。
[0046] 金属散热部件 30上端的冷却面 31可以通过抛光等工序处理， 使得形成光滑的表 面。
[0047] 其中， 如图 2所示， 冷却面 31的至高点 a低于外刀片 20的至高点 b， 且冷却面 31 的至高点 a与安装架 10的上端面具有间距 h， 上述列举的至高点 a及 b均为正常竖直 放置且静止状态下的值。 如此设计， 使得冷却面 31相对于安装架 10的位置更高 ， 这样可以确保金属散热部件 30的冷却面 31能够优先于安装架 10的上端面接触 皮肤， 并且， 金属散热部件 30的冷却面 31又低于外刀片 20的表面， 这样由于外 刀片 20在具体使用时会有一定的浮动， 那么其在浮动时会与该冷却面 31保持尽 可能的齐平， 如此使得金属散热部件 30的冷却面 31与外刀片 20更加贴合地与皮 肤接触。
[0048] 进一步地， 金属散热部件 30闭合环绕于外刀片 20的周侧。 外刀片 20—般为规则 的圆形或者矩形结构， 那么将金属散热部件 30闭合环绕在圆形或者矩形结构的 外刀片 20的外周侧， 这样可以最大面积的设计金属散热部件 30的冷却面 31。 即 优选地， 金属散热部件 30为闭合环形结构， 其形状与外刀片 20的周缘形状相似
[0049] 当然， 金属散热部件 30也可以为非闭合环形结构。 非闭合环形结构的金属散热 部件 30可以是间隔设计的条状结构、 弧状结构或者点状结构构成。
[0050] 另外， 金属散热部件 30还包括至少部分呈圆弧状的弧形段。 金属散热部件 30可 以通过局部的呈圆弧状的弧形段与局部的呈直线状的直线段连接形成。 形成的 金属散热部件 30就可以是封闭的结构也可以是非封闭的结构。
[0051] 当然， 金属散热部件 30还包括至少部分呈直线状的直线段。
[0052] 进一步地， 如图 7所示， 安装架 10的上端位于外刀片 20的周侧设有皮肤接触面 ， 皮肤接触面为金属面 13。 通过在安装架 10上端设置金属结构的皮肤接触面， 同样可以实现与皮肤接触进而传递皮肤中的热量， 进而对该热量进行散发， 实 现降低皮肤上的热感度。 其与金属散热部件 30结合， 能够起到的降温效果更佳
[0053] 其中， 金属面 13可以是整个安装架 10的上端面， 也可以是安装架 10的上端面的 局部位置。
[0054] 具体地， 安装架 10采用塑胶材料制成， 安装架 10的上端注塑成型有金属片， 金 属面 13为金属片的上端面。 金属片可以在安装架 10注塑成型时置于模具中从而 一体成型固定在安装架 10上， 金属片外露出安装架 10上， 如此形成金属面 13。
[0055] 当然， 整个安装架 10可以采用金属材料制成。 这样， 安装架 10的上端面即为金 属面 13 , 其同样可以通过与皮肤的接触实现吸收皮肤上的热量并进行时散发， 有效地降低皮肤上的热感度。
[0056] 本实施例中， 安装架 10和金属片均可以采用铝、 铁或者不锈钢制成。
[0057] 优选地， 金属散热部件 30内置有半导体制冷片 （图未示） 。 半导体制冷片可以 内置于金属散热部件 30内， 半导体制冷片可以更加快读地吸收热量， 更进一步 地提升金属散热部件 30与皮肤接触时快速吸收皮肤中产生热量并散发， 实现快 速对皮肤降温。
[0058] 以下参阅对本实施例的切削单元的测试数据：

Figure imgf000011_0002
Figure imgf000011_0001
[0059] 从以上数据可以看出， 金属散热部件 30的温度明显低于外刀片上的温度， 那么 当外刀片 20的温度传递到皮肤上时， 金属散热部件 30可以有效吸收皮肤上的温 度， 进而降低皮肤的热感度。 [0060] 再参阅附图 8 , 为切削单元的热成像图， 其中金属散热部件 30颜色明显更浅， 表明温度更低， 而 HS所指示的为外刀片 20的温度热点 1， Ml所指示为介于外刀 片 20与金属散热部件 30之间的温度， 而 CS所指示的为外界 （非切削单元） 的温 度冷点 1.
[0061] 实施例二。
[0062] 本实施例提供的一种刀头组件， 其包括刀头外壳 40和至少一个上述的切削单元 ， 各切削单元均安装于刀头外壳 40上， 也即是， 根据实际需求， 可以设计多切 削单元， 例如设计两个切削单元并排布置， 或者三个切削单元环形布置 （参阅 图 4） 。
[0063] 本实施例的刀头组件， 其主要应用于例如剌须装置或者类似于剌须装置等的个 人护理用品上， 组装时， 刀头组件与个人护理用品的手柄组件连接。
[0064] 本实施例的刀头组件， 由于其使用有至少一个上述的切削单元， 那么通过该切 削单元上的金属散热部件 30与皮肤接触， 以使得当皮肤接触此金属散热部件 30 时会有凉爽的感觉。 同时由于该金属散热部件 30不再与其他产生会热量的电动 部件接触， 那么当因为外刀片 20工作而产生高温会给人的皮肤带来不适的感觉 时， 该金属散热部件 30可以有效地吸收皮肤上的热量并进行散发， 进而使得皮 肤得以降温， 大大提升使用的舒适感。
[0065] 本实施例的其余部分与实施例一相同， 在本实施例中未解释的特征， 均采用实 施例一的解释， 这里不再进行赘述。

[0068] 其中， 本实施例的刀头组件与实施例二的刀头组件的主要区别在于： 刀头组件 还包括金属散热部件 30, 金属散热部件 30设于刀头外壳 40的上端或者至少一个 安装架 10的上端， 且金属散热部件 30至少部分环绕于至少一个外刀片 20的周侧 以用于与人体皮肤接触并降低人体皮肤的热感度。 [0069] 本实施例的刀头组件， 通过设置的金属散热部件 30与皮肤接触， 以使得当皮肤 接触此金属散热部件 30时会有凉爽的感觉。 同时由于该金属散热部件 30不再与 其他产生会热量的电动部件接触， 那么当因为外刀片 20工作而产生高温会给人 的皮肤带来不适的感觉时， 该金属散热部件 30可以有效地吸收皮肤上的热量并 进行散发， 进而使得皮肤得以降温， 大大提升使用的舒适感。
[0070] 本实施例的其余部分与实施例一相同， 在本实施例中未解释的特征， 均采用实 施例一的解释， 这里不再进行赘述。

[0073] 其中， 本实施例的刀头组件与实施例二的刀头组件的主要区别在于： 切削单元 还包括金属散热部件 30, 金属散热部件 30设于刀头外壳 40的上端或者安装架 10 的上端， 且金属散热部件 30至少部分环绕于至少一个外刀片 20的周侧以用于与 人体皮肤接触并降低人体皮肤的热感度。

[0080] 实施例六。
[0081] 本实施例提供的一种切削单元， 参阅图 7并结合图 1所示， 切削单元包括安装架 10和外刀片 20, 安装架 10设有贯通其上下两端的刀片腔 11， 外刀片 20安装于刀 片腔 11中并外露出至安装架 10的上端， 安装架 10的上端位于外刀片 20的周侧设 有皮肤接触面， 皮肤接触面为用于与人体皮肤接触并降低人体皮肤的热感度的 金属面 13。 通过在安装架 10上端设置金属结构的皮肤接触面， 可以实现与皮肤 接触进而传递皮肤中的热量， 进而对该热量进行散发， 实现降低皮肤上的热感 度， 能够起到很好的降温效果。
[0082] 其中， 金属面 13可以是整个安装架 10的上端面， 也可以是安装架 10的上端面的 局部位置。
[0083] 具体地， 安装架 10采用塑胶材料制成， 安装架 10的上端注塑成型有金属片， 金 属面 13为金属片的上端面。 金属片可以在安装架 10注塑成型时置于模具中从而 一体成型固定在安装架 10上， 金属片外露出安装架 10上， 如此形成金属面 13。
[0084] 当然， 整个安装架 10可以采用金属材料制成。 这样， 安装架 10的上端面即为金 属面 13 , 其同样可以通过与皮肤的接触实现吸收皮肤上的热量并进行时散发， 有效地降低皮肤上的热感度。
[0085] 本实施例中， 安装架 10和金属片均可以采用铝、 铁或者不锈钢制成。
[0086] 以上所述仅为本申请的较佳实施例而已， 并不用以限制本申请， 凡在本申请的 精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本申请的保 护范围之内。
