Description

一种刀头采用双层弹力结构的剃毛器  技术领域
本发明涉及一种刀头采用双层弹力结构的剃毛器。
 背景技术
市场上现有修剪体毛的刀头技术大致分为两类：
专业设备，长短毛发设备分开剪，需要先用理发剪修剪长毛，修剪后留毛长度会超过一毫米，此时还能明显看到和感觉到留有毛渣；再用往复式剃须刀或刮刀把短毛剃干净，这样才能达到美观和舒适的效果，修剪步骤繁琐，需要设备多。
普通体毛刀，可以同时修剪长毛和短毛，但由于结构和工艺的特点，剪切效率不高，最关键的是动刀、静刀两个刀片直接接触皮肤，存在安全隐患，使用者体验感很差，容易刮伤皮肤。
 技术问题
不管是体毛刀还是剃须刀，其共有的一个缺点是动刀缺乏弹性，导致动刀磨损速度较快；或者弹性结构过于复杂，刀头结构不够紧凑。
 技术解决方案
本发明目的是克服了现有技术能够同时修剪短毛发和长毛发的刀头，其两动刀缺乏弹性或弹性结构过于复杂的问题，提供一种刀头采用双层弹力结构的剃毛器。
本发明是通过以下技术方案实现的：

一种刀头采用双层弹力结构的剃毛器，如图1至图11所示，包括有刀头1和主机2，所述刀头1包括有固定连接的刀头上壳3和刀头下壳4，在所述刀头下壳4的底面设有用于连接所述主机2的连接杆12，在所述刀头下壳4的上方设有用于带动刀片运动的动刀连接件5，在所述动刀连接件5上设有随其一同运动的第一动刀片6、第二动刀固定件8，在所述刀头上壳3安装有第一静刀片7，所述第一动刀片6抵接在第一静刀片7的下表面，在所述第二动刀固定件8上设有随其一同运动的第二动刀片9，在所述第二动刀片9上抵接有第二静刀片10，在所述刀头下壳4与所述动刀连接件5之间设有第一弹性件13，在所述动刀连接件5与所述第二动刀固定件8之间设有第二弹性件14。
本发明刀头1通过第二动刀固定件8驱动第二动刀片9，形成联动机构，刀头1采用双层弹力结构，能够分别为第一动刀片6和第二动刀片9提供稳定的弹力，使所述第一动刀片6的刀齿在往复运动过程中始终与第一静刀片7的刀齿贴合，第二动刀片9的刀齿在往复运动过程中始终与与第二静刀片10的刀齿贴合并且不会卡死，两组刀片互不干扰，受力均衡，从而能够有效提高该剃毛器的工作稳定性，增强剃毛效率和剃毛效果。
使用该剃毛器时，可以先经过所述第一动刀片6和所述第一静刀片7将体毛清除一遍后，再通过所述第二动刀片9和所述第二静刀片10对短茬进行再次清理，剃毛更干净且剃毛效果较好。
所述第一弹性件13可以为弹片或压缩弹簧，当第一弹性件13为压缩弹簧时，在所述动刀连接件5的底面两侧设有第一套柱505，在所述刀头下壳4内设有供所述所述第一套柱505插入的安装槽402，所述第一弹性件13套在所述第一套柱505上，且第一弹性件13的下端抵在所述安装槽402内，上端抵在所述动刀连接件5的底面上。
所述第二弹性件14为压缩弹簧，在所述动刀连接件5的上表面两侧设有第二套柱506，第二套柱506上设有中心孔507，在所述第二动刀固定件8的底面两侧对应所述第二套柱506设有第三套柱802，所述第三套柱802插入所述的中心孔507内，所述第二弹性件14套在所述第二套柱506和所述第三套柱802上，所述第二弹性件14的下端抵在所述第二套柱506上，上端抵在所述第三套柱802上。
本实施例中，在所述第一动刀片6的两端对应所述第二套柱506设有第二通孔602，在所述第一静刀片7的两端对应所述第二套柱506设有腰形孔703，所述第二弹性件14穿过所述第二通孔602和所述腰形孔703套在所述第三套柱802上，中心孔507穿过第一套柱505和第二套柱506。
所述第一静刀片7设有若干个向外侧延伸的静刀刀齿701，所述第一动刀片6设有若干个向外延伸的动刀刀齿604，所述静刀刀齿701的长度大于所述动刀刀齿604的长度，所述静刀刀齿701的齿尖为圆弧端，圆弧端的一面为向所述静刀刀齿701凸出的圆弧面，所述圆弧端相对的另一面与所述静刀刀齿701的表面平齐。
所述动刀刀齿604相对于所述静刀刀齿701做往复运动，所述动刀刀齿604的剪切面滑过所述静刀刀齿701的剪切面时，将毛发进行剪切。其中，将所述第一定刀件30的静刀刀齿701的末端设置为圆弧端32，避免该末端形成尖锐端割伤皮肤，使得静刀刀齿701的厚度可以做得更小，更加贴合于皮肤，从而提高剃毛的干净度，安全性能高，具有更好的舒适性。
所述第二静刀片10和第二动刀片9均采用不锈钢冲压和蚀刻锐角工艺制成。大大减少了刀片的厚度，同时利用蚀刻锐角工艺提升两者配合的锋利度，消费者在使用该刀头进行剃毛、剃须时，具有速度快、效率高的使用感受，同时杜绝在剃毛、剃须时出现扯毛现象。
如图7和图8所示，所述第二静刀片10和第二动刀片9设于所述刀头1的中间，所述第二静刀片10呈网片状，所述第二静刀片10密布有多个进毛孔101，能够无缝衔接二次剃毛功能，所述第二动刀片9设有多个条形孔状的剪切刀刃901，所述剪切刀刃901的角度与水平面呈45度角，所述剪切刀刃901与所述第二静刀片10的内侧面抵接。45度角的刀口使剪切性能在传统圆刀90度刀口基础上提升300%，第二静刀片10的厚度控制在毫米级范围内，保证了双边静刀的刀口平整度。
在所述第一动刀片6上设有多个安装孔603，在所述动刀连接件5上对应设有多个插入所述安装孔603的安装柱503；在所述第一静刀片7上设有设有多个定位孔704，在所述刀头上壳3的底面对应设有多个插入所述定位孔704的第一定位柱301；所述第一动刀片6通过安装柱503被动刀连接件5带动随动刀连接件5一同做往复运动，所述第一静刀片7通过第一定位柱301与刀头上壳3固定连接。
在所述第一静刀片7上设有卡合槽705，在所述第二静刀片10的外侧设有卡入所述卡合槽705内的卡片102，在所述卡片102上设有卡孔103，在所述刀头上壳3上设有卡入所述卡孔103的卡头302；
在所述第二动刀固定件8的外侧设有台阶803，所述第二动刀片9的底部置于所述台阶803上，在所述第二动刀片9的外侧设有定位槽902，在所述第二动刀固定件8上设有卡入所述定位槽902的第二定位柱804；
在所述动刀连接件5上设有两块向上延伸的卡板504，在所述第二动刀固定件8的两边设有向下延伸的扣孔801，在所述卡板504与所述扣孔801扣接固定。所述第二动刀固定件8与所述动刀连接件5扣合固定，使得所述第二动刀片9能够随所述动刀连接件5一同做往复运动。
进一步地，在所述第一动刀片6和所述第一静刀片7上分别设有第一条形孔601和第二条形孔702，所述卡板504穿过所述第一条形孔601、所述第二条形孔702与所述扣板801扣接固定。
上述传动定位结构简单，使得刀头1的内部在宽度方向安装更为紧凑，精度能够控制在±0.02毫米以内。
所述刀头1的两端设有清洁孔15，剃毛完成后可以将所述刀头1置于水龙头下直接冲洗，残留在该剃毛器内部的毛发会轻易的从所述清洁孔15内冲出，清洁方便且干净。
在所述刀头下壳4两边的侧壁上且靠近所述第一动刀片6的刀齿处设有倒毛梳齿11，所述倒毛梳齿11能够引导、理顺杂乱的毛发并将较长的体毛倒向所述第一动刀片6和所述第一静刀片7，提高剃毛效率。
具体的，所述倒毛梳齿11位于所述第一动刀片6的下方，所述倒毛梳齿11与所述第一静刀片7的刀齿一一对应，使倒毛效果更好，提高剃毛效率，所述连接杆12为U形，所述倒毛梳齿11、所述连接杆12与所述刀头下壳4为一体件，一体化的设计能够缩减所述刀头1的零件数量，方便组装，而且在生产时能够一体注塑成型，提高生产效率。
本发明倒毛梳齿11、第一动刀片6、第一静刀片7、第二动刀片9和第二静刀片10，倒毛梳齿11与第一静刀片10的刀齿一一对应，能够引导、理顺杂乱的毛发并将较长的体毛倒向第一动刀片6和第一静刀片7，提高剃毛效率；经过第一动刀片6和第一静刀片7将体毛清除一遍后，可以通过第二动刀片9和第二静刀片10对短茬进行再次清理，剃毛更干净且剃毛效果较好。
在所述刀头下壳4上设有第一通孔401，在所述动刀连接件5的底面上设有两块穿过所述第一通孔401向下延伸的卡块501，两块所述的卡块501之间设有用于联动所述主机2中传动器件的卡槽502。
所述主机2包括有主机外壳20和主机内壳21，在所述主机外壳20的侧壁上设有按键31，在所述主机外壳20的内部底端设有充电接口32，在所述主机内壳21的内部设有电池33，在所述主机内壳21的一侧设有电路板34。
在所述主机外壳20的上方设有刀头连接件22，在所述主机外壳20的内部顶端设有电机25，在所述电机25的电机轴上安装有用于带动所述动刀连接件5做往复运动的转动摆件26，所述转动摆件26的上端置于所述卡槽502内。所述转动摆件26的下端可以以过盈插接的方式固定在所述电机25的电机轴上。所述转动摆件26的上端会因不与所述电机25的电机轴同轴而产生摆动，从而在左右两个方向会分别撞击两块所述的卡块501，带动所述动刀连接件5做往复运动，使得所述第一动刀片6、所述第二动刀片9能够分别相对于所述第一静刀片7、所述第二静刀片10进行往复运动。
所述刀头1通过所述连接杆12可转动的连接在所述所述刀头连接件22上，所述刀头连接件22的下端可拆卸地设在所述主机2的顶部，所述刀头连接件22内设有撬杆28和弹片27，所述连接杆12上设有插孔29，所述撬杆28的一端抵在所述弹片27上，另一端插接在所述插孔29上。
具体的，所述刀头连接件22包括有上连接件23和下连接件24，所述刀头1通过连接杆12可转动的连接在所述上连接件23和所述下连接件24之间，所述连接杆12可以小幅度的在上连接件23和所述下连接件24之间转动，以便于在使用该剃毛器时能够方便的调节所述刀头1的角度，所述上连接件23固定在所述下连接件24上，所述下连接件24的下端与所述主机2以插接或扣接等可拆卸的方式连接，方便更换不同型号的刀头。
所述上连接件23上设有限位孔30，撬杆28的上端穿过插孔29并伸入限位孔30内，转动刀头1可以带动撬杆28一起转动，限位孔30的作用是限制刀头1的转动角度，弹片27的作用是使转动后的刀头1复位。
本发明所述的实施例仅仅是对本发明的优选实施方式进行的描述，并非对发明构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中工程技术人员对本发明的技术方案作出的各种变型和改进，均应落入本发明的保护范围。
