Description
本发明涉及一种旋转剃须刀的刀网结构,本发明还涉及一种旋转剃须刀的刀网结构的加工方法。
目前现有旋转剃须刀的刀网,因为需要在移动时进毛,通常通过在环形的剃须轨道上设置直槽供毛发进入其内,并结合在剃须轨道内旋转运动的动刀进行切割。而由于直槽结构比较容易使皮肤挤压进入,为了保证安全性,不切到皮肤,直槽结构的宽度需做的较小,直槽宽度小则其进毛口细小造成进毛困难,而为了保证进毛的效果,需要设置尽量多的直槽,通常的结构是绕剃须轨道的圆周方向规则均匀密布,密密麻麻的直槽之间形成一条条独立的间隔条,影响肤感。而且直槽通常是从剃须轨道的外环侧面贯穿到内环侧面形成横向贯穿剃须轨道的通槽,以便毛发既可从剃须轨道的外环侧面进毛,也可从内环侧面进毛,以便提高进毛效率,如专利CN201910929923.8中所示的刀网结构,具有内外两个剃须轨道,并在两个剃须轨道上360°均布通槽结构的直槽。当然,除了绕剃须轨道360°均布直槽(其专利中叫毛发接收孔)外,也可以如专利CN200480018064.9中所示的刀网一样,适当的在剃须轨道的顶部设置一些圆形的进毛孔,供较短的毛发和发根***切割。
上述这种通槽结构的直槽,毛发从某一直槽进入后,一种情况是毛发没有从直槽中跑出去前,动刀旋转到该直槽位置从而将进入的毛发切断,另一种情况是在动刀没有旋转到该直槽位置时,毛发已经从直槽中跑出,导致漏发,影响剃毛的效率。并且,由于通常动刀的切割刃宽度是小于剃须轨道的内腔的,并与内腔的内外两侧壁存留间隙,毛发从直槽的一端进入,没有被动刀切割到,而从另一端跑出时,由于直槽壁的内边缘锋利及空间小等限制,会产生扯毛扯发,扯痛皮肤,影响剃毛的舒适性。
当然有些刀网为了解决毛发进入直槽后又跑出的漏毛问题,其直槽不采用通槽结构,只从外环侧面横向往内开设一段距离后截止,并不贯穿内环侧面,然后动刀切割区域覆盖直槽的截止部位,当毛发进入直槽移动到尽头时,如果动刀还没旋转过来,其能够在截止的位置处停顿一段时间并不会跑出去,可供快速旋转的动刀来到后切割,一定程度提高切割的效率,但是其牺牲了从内环侧面进毛的作用。
旋转剃刀技术经过几十年的发展虽然相当成熟,但是旋转剃须刀的刀网基本都脱不开上述的进毛结构。既要安全性和舒适性,又要进毛好且防止漏毛,提高剃毛效率,成了一个悬而未决的技术难题。
本发明就是基于这种情况作出的。

本发明所要解决的另一技术问题是提供一种工艺简单的旋转剃须刀的刀网结构的加工方法。
为解决上述技术问题,本发明一种旋转剃须刀的刀网结构的加工方法,包括以下步骤:
A、冲压出具有凸起的环形剃须轨道的刀网本体;
B、分别利用外切槽砂轮和外边角砂轮与内切槽砂轮和内边角砂轮加工剃须轨道,其中,外切槽砂轮的厚度h1小于外边角砂轮的厚度h2,所述外边角砂轮的两侧设有外切倒角,两个外切倒角之间圆滑过渡,内切槽砂轮的厚度h3小于内边角砂轮的厚度h4,所述内边角砂轮的两侧设有内切倒角,两个内切倒角之前圆滑过渡;

通过内切槽砂轮在剃须轨道的内环侧面和轨道顶面之间切割出内进毛槽,所述内进毛槽从内环侧面开始延伸至剃须轨道中间偏外的位置,通过内边角砂轮两侧的内切倒角在剃须轨道的内环侧面和轨道顶面之间的转折连接处切除刀网本***于内进毛槽两侧的一部分材料,控制切割进给的量,避免内切倒角切穿到剃须轨道内,切出内喇叭导毛口;
在剃须轨道上沿圆周方向分别切割出多个所述外进毛槽和内进毛槽,以及对应的外喇叭导毛口和内喇叭导毛口,其中所述外进毛槽和内进毛槽相互隔开,且所述外进毛槽和内进毛槽沿圆周方向交错分布;
C、对外进毛槽、外喇叭导毛口、内进毛槽和内喇叭导毛口的外表面边缘进行抛光。
为解决上述技术问题,本发明一种旋转剃须刀的刀网结构的加工方法,包括以下步骤:
A、冲压出具有凸起的环形剃须轨道的刀网本体,且在冲压时同时在剃须轨道上冲压出外喇叭导毛口和内喇叭导毛口,所述外喇叭导毛口位于剃须轨道的外环侧面和轨道顶面之间的转折连接处并斜向上方, 所述内喇叭导毛口位于剃须轨道的内环侧面和轨道顶面之间的转折连接处并斜向上方,且外喇叭导毛口和内喇叭导毛口有多个并一一对应且一外一内交错设置;
B、分别利用外切槽砂轮与内切槽砂轮在剃须轨道上切槽,其中所述外切槽砂轮的厚度小于外喇叭导毛口沿圆周方向的宽度,所述内切槽砂轮的厚度小于内喇叭导毛口沿圆周方向的宽度;将外切槽砂轮与外喇叭导毛口对中,在剃须轨道的外环侧面和轨道顶面之间切割出外进毛槽,所述外进毛槽从外环侧面开始延伸至剃须轨道中间偏内的位置;将内切槽砂轮与内喇叭导毛口对中,在剃须轨道的内环侧面和轨道顶面之间切割出内进毛槽,所述内进毛槽从内环侧面开始延伸至剃须轨道中间偏外的位置;在剃须轨道上沿圆周方向分别对应外喇叭导毛口和内喇叭导毛口切割出多个外进毛槽和内进毛槽;

与现有技术相比,本发明有如下优点:
1、本发明的刀网本体上沿圆周方向交错设置多外进毛槽和内进毛槽,且外进毛槽和内进毛槽并非从剃须轨道的外环侧面贯穿到内环侧面的通槽,则毛发可从剃须轨道的外环侧面进毛,也可从内环侧面进毛,进毛效率高,且外进毛槽具有在轨道顶面上的内终止端,内进毛槽具有在轨道顶面上的外终止端,则能够防止进入外进毛槽和内进毛槽内的毛发跑出去,挡在内终止端或外终止端处的毛发在切割刃旋转到该处时被切割掉,既提高了剃毛效率,又避免毛发被拉扯,提 高剃须的舒适性。而由于外进毛槽和内进毛槽为相间交错设置,在外进毛槽和内进毛槽设置成安全的槽宽,避免皮肤挤压进入剃须轨道内被切割到的同时,拓宽了相邻两个外进毛槽之间的间距,创造出一个充盈的空间,利用这个空间,在所述外环侧面和轨道顶面之间的转折连接处设置与外进毛槽相对应并用于将毛发导入外进毛槽中的外喇叭导毛口,虽然减少了外进毛槽的数量,但外喇叭导毛口克服了现有刀网结构的直槽宽度小导致的进毛难的问题,极大限度的增加了该刀网结构的外部进毛效率。而且剃须轨道在进行外进毛槽和内进毛槽交错切割后,剃须轨道的轨道顶面留下一个连续完整的与皮肤接触的接触面,既提高剃须的舒适性,增强肤感,又能防止皮肤挤入剃须轨道内,保护皮肤。
2、本发明由于外进毛槽和内进毛槽为相间交错设置,在外进毛槽和内进毛槽设置成安全的槽宽,避免皮肤挤压进入剃须轨道内被切割到的同时,拓宽了相邻两个内进毛槽之间的间距,创造出一个充盈的空间,利用这个空间,在所述内环侧面和轨道顶面之间的转折连接处设有与内进毛槽相对应并用于将毛发导入内进毛槽中的内喇叭导毛口,从而改善内进毛槽进毛效率。
3、本发明的旋转剃须刀的刀网结构的加工方法,工艺简单,加工出来的刀网结构具有进毛效果好,可防止漏毛,剃毛效率高,皮肤保护性好,剃刮安全性和舒适性好的特点。

下面结合附图对本发明作进一步描述:
如图1至6所示,一种旋转剃须刀的刀网结构,包括刀网本体1,所述刀网本体1上设有凸起的环形剃须轨道2,所述剃须轨道2包括外环侧面21、内环侧面23以及连接外环侧面21和内环侧面23的轨道顶面22,所述剃须轨道2上设有相互隔开的外进毛槽3和内进毛 槽4,所述外进毛槽3从外环侧面21开始延伸至剃须轨道2中部,优选剃须轨道2中间偏内的位置,所述内进毛槽4从内环侧面23开始延伸至剃须轨道2中部,优选剃须轨道2中间偏外的位置,所述外进毛槽3和内进毛槽4分别有多个并各自沿圆周设置,且所述外进毛槽3和内进毛槽4在数量上一一对应且一内一外交错设置。
优选地,所述外进毛槽3和内进毛槽4分别沿剃须轨道2的圆周方向均匀分布。当然,所述外进毛槽3和内进毛槽4可以在剃须轨道2的整个圆周上360°分布,也可以选择在其中某一个角度范围内交替设置外进毛槽3和内进毛槽4。
如图11至13所示,与动刀7结合使用时,所述动刀7包括有在剃须轨道2内旋转切割的切割刃71,所述切割刃71的旋转切割区域70同时覆盖外进毛槽3在轨道顶面22上的内终止端31和内进毛槽4在轨道顶面22上的外终止端41。所述切割刃71的外切割点的旋转轨迹形成旋转切割区域70的外边缘701,所述切割刃71的内切割点的旋转轨迹形成旋转切割区域70的内边缘702。
当然,为了提高切割刃71对外终止端41和内终止端31处毛发的切割效果,所述切割刃71的旋转切割区域70的外边缘701与内进毛槽4在轨道顶面22上的外终止端41之间的距离D1,所述切割刃71的旋转切割区域70的内边缘702与外进毛槽3在轨道顶面22上的内终止端31的距离D2,满足以下关系式:0<D1<0.5mm,0<D2<0.5mm,优选0.1mm<D1<0.3mm,0.1mm<D2<0.3mm。
在图1至图6所示的实施例中,刀网本体1上具有外进毛槽3和 内进毛槽4,且外进毛槽3和内进毛槽4并非从剃须轨道的外环侧面贯穿到内环侧面的通槽,则毛发可从剃须轨道的外环侧面进毛,也可从内环侧面进毛,进毛效率高,且外进毛槽3具有在轨道顶面22上的内终止端31,内进毛槽4具有在轨道顶面22上的外终止端41,则能够防止进入外进毛槽3和内进毛槽4内的毛发跑出去,挡在内终止端31或外终止端41处的毛发在切割刃71旋转到该处时被切割掉,既提高了剃毛效率,又避免毛发被拉扯,提高剃须的舒适性。
而由于外进毛槽3和内进毛槽4为相间交错设置,在外进毛槽3和内进毛槽4设置成安全的槽宽,避免皮肤挤压进入剃须轨道内被切割到的同时,则相邻两个外进毛槽3之间具有较宽的间距,利用这个空间,在所述外环侧面21和轨道顶面22之间的转折连接处设置与外进毛槽3相对应并用于将毛发导入外进毛槽3中的外喇叭导毛口5,虽然减少了外进毛槽3的数量,但外喇叭导毛口5克服了现有刀网结构的直槽宽度小导致的进毛难的问题,极大限度的增加了该刀网结构的外部进毛效率。
而且剃须轨道在进行外进毛槽3和内进毛槽4交错切割后,剃须轨道的轨道顶面留下一个连续完整的与皮肤接触的接触面,如图6所示,所述轨道顶面被外进毛槽、内进毛槽、外喇叭导毛口和内喇叭导毛***错切割,并使轨道顶面留下一个连续完整的与皮肤接触的接触面,该接触面由S型的单元面围成,既提高剃须的舒适性,增强肤感,又能防止皮肤挤入剃须轨道内,保护皮肤。
如图2所示实施例,所述外进毛槽3和内进毛槽4分别在剃须轨 道2上偏心设置,以便不同内进毛槽4在内环侧面23上具有较大的间距,保证内进毛槽4具有一个适当的宽度。同时,由于外进毛槽3和内进毛槽4分别在剃须轨道2上偏心设置,所以外进毛槽3与径向之间产生夹角α,内进毛槽4与径向之间产生夹角β。
如图2所示实施例,由于外进毛槽3和内进毛槽4为相间交错设置,在外进毛槽3和内进毛槽4设置成安全的槽宽,避免皮肤挤压进入剃须轨道内被切割到的同时,则相邻两个内进毛槽4之间具有较宽的间距,利用这个空间,在所述内环侧面23和轨道顶面22之间的转折连接处设有与内进毛槽4相对应并用于将毛发导入内进毛槽4中的内喇叭导毛口6,从而改善内进毛槽4进毛效率。
优选地,所述外喇叭导毛口5和内喇叭导毛口6分别为斜向上方的V形口,且外喇叭导毛口5位于外进毛槽3的两侧,内喇叭导毛口6位于内进毛槽4的两侧。
如图1至6所示,作为外进毛槽3和内进毛槽4的一种实施方式,所述外进毛槽3和内进毛槽4为直槽,结构简单,加工方便。
如图4所示的实施例,为了减小体积,并保证旋转切割区域70覆盖一定深度的内进毛槽4和外进毛槽3,保证较好的切割效率,每一所述内进毛槽4均延伸到其相邻两个外进毛槽3所形成的中间区域30中,从而使外进毛槽3和内进毛槽4在圆周方向上具有叠合区域。
所述剃须轨道2的内顶面24上设有向上内凹并供动刀7的切割刃71在内旋转运动的环形剃须槽25,所述外进毛槽3从外向内延伸超过剃须槽25的中心位置250且终止于剃须槽25的中心位置250与 剃须槽25的内槽壁251之间,所述内进毛槽4从内向外延伸超过剃须槽25的中心位置250且终止于剃须槽25的中心位置250与剃须槽25的外槽壁252之间。
如图7至10所示,一种制造上述旋转剃须刀的刀网结构的加工方法,包括以下步骤:
A、冲压出具有凸起的环形剃须轨道2的刀网本体1;
B、分别利用外切槽砂轮101和外边角砂轮102与内切槽砂轮104和内边角砂轮105加工剃须轨道2,其中,外切槽砂轮101的厚度h1小于外边角砂轮102的厚度h2,所述外边角砂轮102的两侧设有外切倒角103,两个外切倒角103之间圆滑过渡,内切槽砂轮104的厚度h3小于内边角砂轮105的厚度h4,所述内边角砂轮105的两侧设有内切倒角106,两个内切倒角106之前圆滑过渡;
通过外切槽砂轮101在剃须轨道2的外环侧面21和轨道顶面22之间切割出外进毛槽3,所述外进毛槽3从外环侧面21开始延伸至剃须轨道2中间偏内的位置,通过外边角砂轮102两侧的外切倒角103在剃须轨道2的外环侧面21和轨道顶面22之间的转折连接处切除刀网本体1位于外进毛槽3两侧的一部分材料,控制切割进给的量,避免外切倒角103切穿到剃须轨道2内,切出外喇叭导毛口5;
通过内切槽砂轮104在剃须轨道2的内环侧面23和轨道顶面22之间切割出内进毛槽4,所述内进毛槽4从内环侧面23开始延伸至剃须轨道2中间偏外的位置,通过内边角砂轮105两侧的内切倒角106在剃须轨道2的内环侧面23和轨道顶面22之间的转折连接处切 除刀网本体1位于内进毛槽4两侧的一部分材料,控制切割进给的量,避免内切倒角106切穿到剃须轨道2内,切出内喇叭导毛口6;
在剃须轨道2上沿圆周方向分别切割出多个所述外进毛槽3和内进毛槽4,以及对应的外喇叭导毛口5和内喇叭导毛口6,其中所述外进毛槽3和内进毛槽4相互隔开,且所述外进毛槽3和内进毛槽4沿圆周方向交错分布;
C、对外进毛槽3、外喇叭导毛口5、内进毛槽4和内喇叭导毛口6的外表面边缘进行抛光。
在步骤B中,外进毛槽3加工时,加工完一个外进毛槽3后,将刀网本体1退出,旋转一个角度,再重新进给加工下一个外进毛槽3,直到加工完成所有的外进毛槽3后,再进行外喇叭导毛口5的加工;在加工完成所有的外喇叭导毛口5后,同理,再加工出所有的内进毛槽4,然后再对应的内进毛槽4加工内喇叭导毛口6。
该旋转剃须刀的刀网结构的加工方法,工艺简单,加工出来的刀网结构具有进毛效果好,可防止漏毛,剃毛效率高,皮肤保护性好,剃刮安全性和舒适性好的特点。
该旋转剃须刀的刀网结构还可以采用以下加工方法,包括以下步骤:
