Description

一种纹绣针头及纹绣装置 技术领域
本发明涉及纹绣工具技术领域，尤其涉及一种纹绣针头及纹绣装置。
背景技术
纹绣是一种破皮上色的化妆方法，将色料刺进皮肤，并到达一定深度，以保留数月到数年，目前主流市场需求的半永久纹绣，是需要将色料留在较浅的皮层，即表皮与真皮之间或真皮靠近表皮的层次，获得留色1-2年就可以自然代谢的纹绣。
现阶段为了获得块状、条状或点状的上色，纹绣师一般会使用一种排针装置来达到上述上色要求。但现有排针装置在纹绣上色过程中，不仅容易发生针丝与针丝之间的弹性震荡，导致色料飞溅影响操作；还容易发生入刺过深，色料在皮下扩散到目标区以外，导致色料变蓝数年残留，即纹绣中的“晕色”事故。当入刺过深时现有排针装置不仅易导致针尖弯折，增加皮肤损伤，还易导致上色慢、操作久、修复期延长的问题，进而增加皮肤感染率、降低留色率。
再者，现有的排针装置在使用时是依靠纹绣师手持，凭借肉眼和经验入刺皮肤的，不能科学的控制入刺深度，更易导致纹绣事故的发生。
进一步的，现有纹绣工具的这种排针装置，使用后不容易被毁损，在拆卸和抛弃过程中易误伤他人，产生接触污染，甚至被重复使用，产生血液疾病传播风险。
因此，亟需提出一种新的技术方案来解决现有技术中存在的问题。

在本发明的描述中，需要理解的是，术语“上”、“下”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或者元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。在本发明的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
下面结合附图与实施例进一步说明本发明要旨。
实施例1：
为获得块状、条状和点状的上色，现有纹绣装置主要是用单排磨尖的金属针丝作为操作端，再将单排针丝焊接到针柄上，通过针柄上的固定端，固定到纹绣笔杆上，形成一种排针装置。通常采取这种排针装置完成以下三种上色手法：1、割线上色，即单排针丝形成纵列，前后依次破皮反复拉划皮肤，可获得条状的上色；2、扫雾上色，即单排针丝形成横列，同时并排运动，反复扫擦破皮皮肤，可获得块状的上色；3、点刺上色，即单排针装置，垂直对准皮肤，针丝前端形成的直线平行于皮肤，反复上下扎刺，可获得一排点状上色。
但是，使用上述这种排针装置在纹绣上色过程中，无论割线、扫雾还是点刺上色，都容易发生针丝与针丝之间的弹性震荡，导致色料飞溅影响操作；也容易发生入刺过深，色料在皮下扩散到目标区以外，导致色料变蓝数年残留，即纹绣中的“晕色”事故；还容易发生针尖弯折，增加皮肤损伤，导致上色慢、操作久、修复期延长，从而感染率增加、留色率降低的问题，且这种排针装置都是帧数针丝结构，使用后不容易被毁损，在拆卸和抛弃过程中易误伤他人，产生接触污染，甚至被重复使用，产生血液疾病传播风险。
可参见图1-6，为现有排针装置在不同使用场景下的结构示意图，其中：排针装置1000；金属针丝1100；焊接区1200；固定端1300；表皮2000。如图1所示，展示的一种现有纹绣工具的单排排针装置1000，包括一端磨尖的多根金属针丝1100，以及与纹绣笔固定的固定端1300，所述多根金属针丝1100等距焊接于焊接区1200上，现有纹绣工具的单排排针装置1000，露出焊接区的针尖长度一般在3mm-30mm，远大于人面部表皮的厚度，人面部表皮平均厚度为0.2-1.0mm。
如图2所示，由于没有入刺深度的设计，当单排针装置1000在表皮2000操作上色时，容易操作入刺到皮下K1、K2、K3不同的深度，导致上色深浅不均或过深发生“晕色”。
如图3所示，当单排针装置1000在表皮2000上做割线上色，即单排针丝形成纵列，按图3中箭头方向前后依次破皮反复拉划操作，当离开皮肤时，如图4所示，当单排针装置1000的针丝1100会发生弹性形变，相互触碰导致色料飞溅。
如图5所示，当单排针装置1000在表皮2000上做扫雾上色，即单排针丝形成横列，按图5中箭头方向同时并排运动，反复扫擦破皮皮肤，需要针丝间距始终保持均等，针尖入刺皮肤深度均等，才可获得块状的均匀上色。
如图6所示，当单排针装置1000入刺皮肤反复扫雾上色时，由于皮肤角质层的厚度、韧性不同，所述单排针装置1000的每根针丝沿图6中箭头方向移动时遇到的阻力不同，针尖M会发生不同程度的弯折，导致再 次入刺皮肤的时候，针丝间距发生改变，入刺深度深浅不一，不仅皮肤损伤而且上色不均。
因此，为了解决现有纹绣装置的不足，本发明旨在提供一种单排入刺深度可预先准确限定的纹绣针头，该纹绣针头可割线、扫雾、点刺多用，不仅可以防止针丝震荡喷色，也可限制入刺过深，发生“晕色”，还可减少针尖弯折，减少皮肤损伤，增加上色的均匀度和有效上色率，从而提高纹绣效率和良率，同时增加纹绣工具用后易损毁设计，防止重复使用和抛弃污染。
下面结合图7(a)-7(d)对本发明所述纹绣针头的具体结构进行说明：图7(a)为在一种实施例中本发明所述纹绣针头的结构示意图；图7(b)为一种实施例中本发明所述针刺部的结构示意图；图7(c)为另一种实施例中本发明所述针刺部的结构示意图；图7(d)为一种实施例中本发明所述导流体的结构示意图。

实施例2：
参见图9，图9中的纹绣针头包括针刺部140、导流体110，以及设置在导流体110外壁上的毛细储液单元120。继续参见图10(a)，图中的刺凸141包含预先固定入刺长度的4个针齿1412，以及安装所述针齿1412的1个基板，如图所述针齿1412为锥形，所述基板1411与所述针齿a、b、c、d一体成型，所述基板1411形成入刺的深度限位。继续参见图10(b)，图中的刺凸141包含预先固定入刺长度的4个针齿1412，以及安装所述针齿1412的4个基板。继续参见图10(c)，为在一种实施例中的针刺部的截面图，4个针齿a、b、c、d等高且等间距排列，针齿a、b间的中心间距为D1，针齿b、c间的中心间距为D2，针齿c、d间的中心间距为D3，D1＝D2＝D3。
图10(d)为在一种实施例中所述刺凸所在基板短边的截面图，参见图10(d)，所述刺凸上任意1个针齿底部直径为d4，高度为h4，经发明人反复实验，为获得更好色料导流效果，20μm≤d4≤500μm，50μm≤h4≤1000μm，且d4<h4。
继续参见图10(d)，在一种实施例中，本发明所述基板1411可以是任意多边形，所述针齿1412设置在基板1411的一侧板面上，为获得更好色料导流效果，记所述基板1411的最小边长为d1411，当d1411>d4时，可以获得更好色料导流效果，使得色料可以自较粗的导流柱111上流至基板1411，再由基板导流至针齿1412上。
如图11(a)所示，所述导流体110为条状物，包括导流柱111和连接杆112，所述导流柱111靠近刺凸141，其为一段上下等大的方柱体，导流柱111和连接杆112固定连接，所述导流柱111可与刺凸141的基板1411粘贴固定。
如图11(b)所示，所述导流体110外壁设有若干条槽道C1、C2、C3……Cn，所述若干条槽道115的毛细储液空间构成毛细储液单元120，所述若干条槽道C1、C2、C3……Cn，均可将色料导向所述刺凸141方向如图11(b) 中的箭头所示。
如图12(a)和图12(b)所示，所述刺凸141所设基板1411的短边长度记为d1411，所述导流体110的导流柱111的高度为G111，导流柱111的第一端面1111的最短边长为D1111，经发明人反复实验，为具有一定的刚性，180 μm≤D1111 ≤1800μm ，为获得更好色料导流效果D1111≥d1411，本实施例为了获得更多的带墨量，且可持续缓释供墨则G111>2×D1111，即所述导导流柱111的高度G111大于2倍的所述导流体110近刺凸141的最短边长D1111。当然，所述刺凸141所在基板1411的横截面可为任意多边形，比如三角形、四边形、五边形等规则或不规则多边形，若基板1411的形状为多边形时，所述导流柱111的轴向长度至少是所述导流柱111的第一端面1111的最短边的长度的2倍，且所述导流柱111的轴向长度大于所述第一端面1111的最长边的长度。
如图13(a)所示，所述纹绣针头100蘸取色料(本文所述的色料、墨均代指可以对皮肤着色的染料)时，其上设有的毛细储液单元120利用毛细原理将色料吸起，并经行临时存储，色料沿着毛细储液单元120的槽道上升，形成色料液柱的高度为记为G300。根据发明人数据收集与分析，常温下现有纹绣色料的密度大约为0.7-1.3 1g/ml，常温下色料液体的表面张力接近于水的表面张力大约是72mN/m；毛细公式：毛细液柱上升高度h＝2*表面张力系数*cosθ/(液体密度*重力加速度g*毛细管半径r)，θ为液面与毛细管壁的交角，所设的毛细储液单元120的槽道半径(或槽道深度和/或宽度)对应于毛细公式中毛细管半径r；根据发明人的实验测试和毛细公式验证，毛细储液单元120的槽道半径(或槽道深度和/或宽度)越小，G300数值越大。即所述毛细储液单元120的槽道115越细，所述的色料液柱就可以被吸起越高，携带的的色料越多，不需要反复沾色，利于连续操作提高效率。本实施例中例举的纹绣针头100的导流体110采取塑料材质，以现有主流生产工艺的精度，所述毛细储液单元120的槽道半径可以精确到0.1mm左右，则色料液柱的高度G300可超过100mm，但是如图13(b)所示，根据操作者手握纹绣针的常规方式和人手部的常规尺寸的测算，手抵触纹绣针的最低位置E一般不超过50mm，所以本实施例所述的纹绣针头100 上所设的毛细储液单元120的槽道高度小于50mm。
如图14(a)所示，刺凸141可粘贴在导流柱的第一端面1111上，得到如图14(b)、14(c)所示的结构图，为获得更好色料导流效果，本实施例所述刺凸141所在基板1411的至少一边(Y1、Y2)和所述导流体110的第一端面1111的外壁边缘对齐(或无限接近)。
在一种实施例中，至少有一个所述刺凸141的所述基板1411设置在所述导流体110的一端端面的中部，且所述基板的一角或一边与所述导流体的外壁边缘的距离不超过0.18毫米。即在一种情况下，基板可以居中设置在第一端面上，但为了获得更好的导流效果，基板的一角或一边与所述导流体的外壁边缘的距离不超过0.18毫米。
如图15所示，本实施例所述的纹绣针头100，其导流体110和刺凸141具有黏贴缝隙，在使用完毕后，可用利器分离导流体110和刺凸141，对使用后的纹绣针头100做出功能性损毁。

如图16(b)所示，所述刺凸141包括预先固定入刺长度的3针齿，以及安装所述针齿1412的一个基板1411，所述3针齿可以为塔形也可为锥形，图示为锥形，所述基板1411与3尖齿针齿一体成型，所述基板1411形成入刺的深度限位。
如图16(c)所示，所述导流体110为条状物，包括导流柱111和连接杆112，所述导流柱111靠近刺凸141，其为一段上下等大的柱状体，所述导流柱111包含12根切平的金属丝(图示的金属丝仅是示意性的展示了所述导流柱的一种结构形式，所述的金属丝也可以指代为平头针丝113或小柱体114)C1、C2、C3……C12，所述金属丝C1、C2、C3……C12，相邻而非固定连接，之间的缝隙具有毛细作用形成毛细储液单元120，所述导流柱111和连接杆112固定焊接。
如图17(a)和图17(b)所示，为获得更好色料导流效果，所述基板 1411的横截面的长边L1411，小于或等于导流柱111的第一端面1111的长边L111，即L1411≤L111；所述基板1411的横截面的短边D1411小于或等于导流柱111的第一端面1111的短边D1111。
如图18(a)、18(b)所示，刺凸141的基板1411其中一长边P1与所述导流柱111外壁边缘对齐(无限接近)。或如图18(b)所示，刺凸141的基板1411的两长边M1、M2与所述导流柱111外壁边缘对齐(无限接近)。
如图19所示，本实施例所述的纹绣针头100，其导流体110和刺凸141焊接固定，刺凸141采用单晶硅材质，使用完毕后可用利器敲断所述的针齿，对所述的纹绣针头做出功能性损毁。
实施例4：
在一种实施例中，如图20(a)所示，为一种单排入刺深度可预先准确限定的纹绣针头100，设有刺凸141，导流体110和毛细储液单元120，
所述导流体110与刺凸141连接固定。如图20(b)所示，所述刺凸141包括，预先固定入刺长度的4针齿，以及安装所述针齿的基板1411，所述4针齿为塔形，所述基板1411与4针齿一体成型，所述基板1411形成入刺的深度限位。如图20(c)所示，在一种实施例中，所述导流体110为条状物，包括导流柱111和连接杆112，所述导流柱111近刺凸141为一段柱体，所述导流柱111外壁或一侧贴附纤维状物质，纤维状物质本体的空隙，以及所述纤维状物质本体与所述导流柱111外壁之间的空隙，形成毛细储液单元120。
实施例5：
继续参见图7(a)至图7(d)，在一种实施例中，本发明所述的一种纹绣针头100，其大体可以包括导流体110以及设置于所述导流体110一端的针刺部140，所述针刺部140包括至少一个刺凸141，所述刺凸141包括基板1411和针齿1412，所述针齿1412固定于所述基板1411的一侧板面上，所述针齿1412的中心轴线与所述基板1411的板面相垂直，在下针入刺时，该基板1411可以形成下针的深度限位，基板1411与皮肤相贴，以此限制针 齿1412的刺入深度。图7(b)中示出的针刺部包括一个刺凸141，该刺凸141包括一个基板1411和设置在该基板1411上的4个针齿1412。图7(c)中示出的针刺部包括四个刺凸141，每个刺凸141包括一个基板1411和设置在该基板1411上的一个针齿1412(或多个针齿，图示中基板上设置一个针齿)。所述导流体110为柱状导流体110，所述基板1411的另一侧板面固定于所述柱状导流体110的一端，所述柱状导流体110的中心轴线与所述针齿1412的中心轴线相平行。这样的结构类似钢笔，导流体110类似笔杆，针刺部140类似笔头，竖直下笔保证下针位置不偏移、不打滑、不造成多余创口。
继续参见图7(a)至图7(d)，在一种实施例中，本发明所述的导流体110可以包括导流柱111及与所述导流柱111相连的连接杆112，即将导流体110分为两个部分，一部分导流，另一部分连接驱动，所述连接杆112与驱动部相连，所述导流体110在所述驱动部的驱动下沿所述导流体110的中心轴线往复移动。在一种情况下，所述的驱动部可以是电动笔杆，即将导流体110的连接杆112直接与电动笔杆相连(可以是固定连接也可以是非固定连接(包含抵接、挂接、触接))，电动笔杆直接驱动导流体110运动。在另一种情况下，所述的驱动部可以是弹性件170，比如弹簧，将导流体110的连接杆112与弹簧的一端相连，套筒(或与套筒固定连接的部件)与弹簧的另一端相连，然后通过外力驱动使得弹簧发生弹性形变，所述导流体110沿着套筒150轴向向出针端运动时，在弹性形变力作用下复位，从而在所述套筒150内，形成往复运动。在另一种情况下，操作者也可直接拿握连接杆112直接进行纹绣操作。
为了适应不同的纹绣花样及纹绣位置，本实施例提供一种刺凸141，可参见图7(b)，所述刺凸141可以包括一个基板1411以及设置在所述基板1411上的4个针齿1412，所述基板1411形成所述针齿1412入刺的深度限位板，所述基板1411与所述针齿1412可以一体成型也可以分体式固定连接，相对而言基板1411与针齿1412一体成型连接能够增强针齿1412的连接强度及稳定性，下针入刺过程中针齿1412的安全性更高，更适宜高频的入刺过程。
下面将结合图6和图8说明本发明所述纹绣针头相对现有排针装置的 优越性：
见图6，当单排针装置1000入刺皮肤反复扫雾上色时，所述单排针装置1000的每根针丝遇到的阻力不同，针尖M会发生不同程度的弯折，针丝间距也会发生改变。再参见图8，当使用本发明所述的纹绣针头进行反复扫雾上色或者拉划点刺等操作时，针齿入刺皮肤的深度通过基板1411可控，各个针齿间不会发生挤压或者弹性形变，在使用过程中可以保持各个针齿不相影响，控制入刺深度，不弯折，因此，本发明所述纹绣针头无论从使用效果上还是结构设计上均优越于现有排针装置。
实施例6：
继续参见图9，在一种实施例中，本发明所述的导流柱111可以具有第一端面1111和第二端面1112，所述导流柱111的中心轴线分别贯穿所述第一端面1111的中心和所述第二端面1112的中心，所述导流柱111可以是任意柱状体，比如圆柱体、四方柱体、类锥状柱体或称为圆台、异形柱体等。所述基板1411的一侧板面固定于所述导流柱111的第一端面1111(基板可与第一端面粘贴固定)，所述导流柱111的第二端面1112上固定连接或可拆卸连接有连接杆112，该连接杆112可以是柱状体也可以是其他形状，其主要用于连接导流柱111和驱动部。
在一种实施例中，本发明所述导流柱111的形状可以是任意的，其只需满足以下任意一个条件即可：
条件1：所述第一端面1111的形状和尺寸与所述第二端面1112的形状和尺寸相同；
条件2：所述第一端面1111的形状与所述第二端面1112的形状相同，且所述第一端面1111的尺寸小于所述第二端面1112的尺寸；
条件3：所述第一端面1111的形状与所述第二端面1112的形状不相同，且所述第一端面1111的尺寸小于所述第二端面1112的尺寸。
结合上述3个条件可以看出，其实导流体110的最基本的特征即是一个柱状体，其能够满足在竖直状态下的导流、引流即可，至于形状则是任意的，可根据用户需求自行设计使用，附图中主要体现的是形状是柱体状 和类锥状，仅在于说明导流体的结构，不可理解为对导流体形状的限制。
在一种实施例中，本发明所述的导流柱111的轴向长度大于所述导流柱111的第一端面1111的横截面的长边长度或直径长度。即本发明所述导流柱111最好是细长型的柱体结构。
在一种实施例中，所述导流柱111的轴向长度至少是所述导流柱111的第一端面1111的最短边的长度或直径长度的2倍，且所述导流柱111的轴向长度大于所述第一端面1111的最长边的长度或直径长度。满足这一长径比则进一步规范了导流体110的外形比例，竖直状态下细长的导流体110具有良好的导流及储液作用。
实施例7：
纹绣过程中需要将纹绣用墨300(或称染料)通过纹绣工具导入到皮肤浅表层，现有的纹绣工具每次浸润墨300后吸附的墨300不多，在高频次的入刺过程中，纹绣工具上的墨量达不到一个阶段入刺过程中的墨量，导致纹绣下针的空针率较高。为了改善现有纹绣工具的上述缺点，本发明提出的纹绣针头对导流体110进行了改进，以满足纹绣过程中的吸墨量。下面具体说明本发明所述导流体110的结构：
参见图11(a)、11(b)和图12(a)、12(b)，以及图13(a)、13(b)，于本发明所述导流柱111上设置毛细储液单元120，所述毛细储液单元120反重力吸附液体后临时储存液体，液体(在重力作用下或其它力的作用下)被导流至所述针刺部140，所述针齿1412入刺皮肤表层，同时液体随所述针齿1412被导入皮肤表层。这种毛细储液单元120可以临时储墨300，将导流体110浸润于墨瓶中，导流体110上的毛细储液单元120会吸附墨汁，且对吸附的墨汁进行临时存储，当导流体110带着针刺部140的针齿1412入刺皮肤时，毛细储液单元120内储存的墨300会逐渐被导流至针齿1412尖端，本发明通过毛细储液单元120实现了导流体110的逐步输墨，保障了持续供墨，降低了空针率。
由上述可见，纹绣针头在用于纹绣过程中是需要透皮的，因此，已被使用过的纹绣针头是需要被损毁掉的，以防止二次利用后引起病菌微生物 的传播，而本发明提供的纹绣针头也已考虑到这个问题。因此，见图15和图19，可以将纹绣针头的针齿1412毁掉也可将纹绣针头的针刺部140直接毁掉，如此一来剩余的导流柱111还可进一步重复使用。
请继续参见图11(b)，在一种实施例中，本发明所述导流柱111上设置有若干个槽道115，所述槽道115沿所述导流体110的轴向方向设置于所述导流柱111的外壁和/或所述导流柱111的内部，若干个所述槽道115共同组成所述毛细储液单元120。毛细储液单元120主要是为了持续向针齿1412尖端供墨300，因此，至少有一个所述槽道115临时储存有液体，且所述槽道115内的液体在重力作用下能被导流至所述针刺部140的所述针齿1412上。本实施例所述的槽道115可以通过蚀刻、切割、刻磨或者注塑等方法于导流体110外壁一体成型。
在一种实施例中，本发明所述导流柱111的外壁上设置有若干个所述槽道115，若干个所述槽道115组成所述毛细储液单元120。本实施例所述的槽道115可以是外接至导流柱111的针丝或针管等可以形成间隙的物体。
继续参见图16(a)至图16(c)，在一种实施例中，本发明所述导流柱111可以由若干个平头针丝113和/或若干个小柱体114组成，若干个所述平头针丝113和若干个所述小柱体114相邻排列，或若干个所述平头针丝113相邻排列，或若干个所述小柱体114相邻排列，相邻两个所述平头针丝113的排列间隙形成组成所述毛细储液单元120的槽道115，相邻两个所述小柱体114的排列间隙形成组成所述毛细储液单元120的槽道115，一个所述平头针丝113与一个所述小柱体114的排列间隙形成组成所述毛细储液单元120的槽道115。本实施例所述的针丝或小柱体114可以是实心的也可以是空心的，可以通过拼接形成的缝隙形成毛细作用，也可以在此基础上通过空心针丝或空心小柱体114的管道形成辅助毛细作用。
实施例8：
继续参见图20(a)，本发明所述的毛细储液单元120还可以通过外部贴附实现，本实施例提供一种储液结构130，所述储液结构130由一个或多个片状物组成，所述片状物贴附在所述导流柱111的外壁上，且与所述导流柱 111的外壁形成空隙，所述空隙形成所述毛细储液单元120，所述毛细储液单元120内临时储存有液体，所述液体被导流至所述针刺部140的所述针齿1412上。
在一种实施例中，所述储液结构130由天然或人造多孔物质切片组成。
在另一种实施例中，所述储液结构130由若干根丝状物组成，所述丝状物包括纤维丝131，若干根所述纤维丝131之间的空隙，以及所述纤维丝131与所述导流柱111外壁之间的空隙形成所述毛细储液单元120，所述毛细储液单元120内临时储存有液体，且所述液体被导流至所述针刺部140的所述针齿1412上。
在一种实施例中，所述纤维丝131可以包括动物毛发、植物纤维丝131和化纤丝等。
在一种实施例中，所述丝状物还可以包括金属丝，若干根所述金属丝之间的空隙，以及所述金属丝与所述导流体110外壁之间的空隙形成所述毛细储液单元120，所述毛细储液单元120内临时储存有液体，且所述液体被导流至所述针刺部140的所述针齿1412上。
在一种实施例中，储液结构130的贴附位置及贴附面积可以根据储液结构130的单位储墨量、导流体110的目标储墨量进行决定，有需要还可根据用墨量对储液结构130的层数、面积等进行自定义修改。
实施例9：
本发明提供的纹绣针头作为一种纹绣工具可以将纹绣用墨300导入至皮肤浅表层，因此，导流体110上吸附的墨300与针齿1412之间应该能够形成一个导流通路，确保导流体110上的墨300可以流至针齿1412尖端，以被导入皮肤。因此，本发明所述的纹绣针头中，应至少有一个所述刺凸141的所述基板1411的一角或一边靠近所述导流体110的外壁边缘，以使得设置于所述基板1411上的所述针齿1412可自所述导流体110上接收液体。这样的结构设计才能有效形成液体通路，降低下针空针率。可参见图18(a)及图18(b)，自图中可以看出刺凸141的基板1411的外边缘与导流柱111的外边缘有基本对齐的部分，而这对齐的部分则可以保证导流柱111上的 墨可以顺利流至针齿1412的尖端。
在一种实施例中，所述刺凸141的所述基板1411的一角或一边与所述导流体110的外壁边缘基本对齐。
在另一种实施例中，所述刺凸141的所述基板1411设置在所述导流体110的一端端面的中部，且所述基板1411的一角或一边与所述导流体110的外壁边缘的距离不超过0.18毫米。
实施例10：
参见图21至图23，还可以为本发明提供的纹绣针头配备一个套筒150，将导流体110装设至套筒150内部，导流体110可以在套筒150内往复运动完成下针动作。
在一种实施例中，本发明所述套筒150可以是一个管状筒体，见图23，所述套筒150可以具有紧固端151、中间连接管152和出针端153，所述紧固端151、中间连接管152和出针端153依次相连形成供所述导流体110往复移动的通道，所述紧固端151的中心轴线，以及所述中间连接管152的中心轴线分别与所述套筒150的中心轴线重合。
在一种实施例中，本发明所述紧固端151可与外部驱动件可拆卸连接(易于更换纹绣针头)，所述出针端153设置有出针口1531，针齿1412在出针口1531附近往复运动。所述导流体110及设置于所述导流体110一端的针刺部140沿所述套筒150的中心轴线安装于所述套筒150的中间连接管152内，所述导流体110靠近所述紧固端151，所述针刺部140靠近所述出针端153，所述导流体110于所述中间连接管152内往复移动，且所述导流体110带动所述针刺部140的所述针齿1412外伸出所述出针口1531或回缩至所述出针口1531内。
在一种实施例中，本发明所述套筒150的出针端153可以是管筒状。
所述出针口1531可以是平头端口，也可以是坡形端口。
若出针口1531是平头端口，则当所述导流体110于所述套筒150的出针端153的所述出针口1531处自由往复移动时，所述导流体110的外壁与所述出针端153的内壁之间的空隙形成组合毛细空间，针头吸液时所述组 合毛细空间内临时储存有液体，且所述组合毛细空间临时储存的液体在重力作用下被导流至所述针刺部140，且在所述针刺部140的所述针齿1412的入刺过程中被导入皮肤表层200。

实施例11：
实际纹绣过程中纹绣针头基本是处在一个相对高频的作业环境中，因此下针过程中容易发生偏移、歪斜造成滑针，因此，本发明提供一种纹绣针头，以对导流体110形成限位，辅助导流体110在下针过程中直进直出，精准入刺。
参见图24(a)至图24(e)，本发明提供的导入针头的套筒150内设置有限位结构160，所述限位结构160设置于套筒150的中间连接管152内和/或所述套筒150的紧固端151上和/或所述套筒150的出针端153上，当所述导流体110沿所述套筒150的中心轴线往复移动时，所述导流体110与所述限位结构160可以发生抵靠，所述限位结构160限制所述导流体110在所述套筒150的横截面方向上的摆动，以使得所述导流体110带动所述针刺部140的针齿1412竖直自所述套筒150伸出直至所述针齿1412入刺至皮肤表层200，且使得所述导流体110带动所述针刺部140的针齿1412于出针口1531外竖直回缩至所述套筒150内。

在一种实施例中，本发明所述限位结构160可以是限位管162。所述限位管162具有一个通道，所述通道的的中心轴线与所述导流体110的中心轴线可以重合也可以不重合。通道的内径与导流体110的外径相适应(所述通道的形状与尺寸与所述导流体110的最大横截面的形状与尺寸相适应，此处的适应并不是指通道的形状与尺寸与所述导流体的最大横截面的形状与尺寸一致，而是为了保证导流体可以自通道内穿过。在一种情况下，圆柱状的导流体也可以配合一个截面为方形的通道，此时圆柱状的导流体与方形通道的间隙也可以形成毛细作用用于储液)，保证导流体110可于中心通道内直进直出，中心通道对导流体110形成限位作用。
在一种实施例中，参见图24(e)，本发明所述限位结构160可以是限位挡板164。所述限位挡板164具有限位板面，所述限位板面所在的平面与所述导流体110的中心轴线形成夹角(在一种情况下限位板面所在的平面与所述导流体110的中心轴线也可以相平行)，所述导流体110沿所述套筒150的中心轴线往复移动时，所述导流体110与所述限位板面相抵靠，所述限位板面限制所述导流体110在所述套筒150的横截面方向上的摆动。本发明所述限位挡板164可以设置在套筒150的出针端153的出针口1531处，该限位挡板164可以是一个也可以是多个，若是有多个限位挡板164其可以在出针口1531均匀排布围成一个通道，针刺部140可在该通道内直进直出。
参见图24(c)、24(d)，在一种实施例中，本发明所述限位结构160可以是限位支架163，所述限位支架163设置在所述套筒150的一端(也可以设置在套筒内部)，所述限位支架163包括一个或多个子支架，所述子支架的一边与所述导流体110相抵靠，所述子支架限制所述导流体110在所述套筒150的横截面方向上的摆动，当所述导流体110沿所述套筒150的中心轴线往复移动时，所述导流体110与所述子支架的一边相抵靠，且所述导流体110在所述子支架的抵靠作用下将所述导流体110导向至所述套筒150的出针口1531。
本实施例所述的限位结构160可以有效限位，为导流体110进行限位、导向，保证下针位置精准、不歪斜打滑。
实施例12：
继续参见图24(a)至图24(c)，本发明所述的导入针头100还可以包括一个弹性件170，比如弹簧、硅胶件或橡皮筋。所述弹性件170的一端与套筒150相连，另一端与导流体110的连接柱相连(弹性件与套筒或导流体的连接方式多样，可以抵接、套接或者挂接等)，套筒150与电动笔杆相连，则当所述导流体110被外力驱动(电动笔杆的电机启动后给导流体110一个驱动力)沿所述套筒150的中心轴线向所述套筒150的出针口1531方向移动时，所述弹性件170发生弹性形变牵引所述导流体110回复至初始位置。
实施例13：
不同的纹绣图案及纹绣位置会用到不一样的纹绣针头，本发明还提供一种纹绣针头100，该纹绣针头的刺凸141包括一个个基板1411以及设置在所述基板1411上的单个针齿1412。单个针齿的纹绣针头更适合单点小范围点刺形成纹绣图案。
本发明所述的多个排列成排的针头可以用来纹线性较长且过渡弧度较小的图案，相比单个针齿的针头来说，这种多个针齿的针头对这种特定图案由这效率上的优势。当然，对于点状的、或者线性过渡较大的图案还是单个针齿的针头更有优势。
实施例14：
在本发明所述的纹绣针头的基础上，本发明还提供一种纹绣装置，该纹绣装置包括上述任一所述的纹绣针头100，及驱动所述纹绣针头100的导流体110运动的外部驱动件。
在一种实施例中，所述外部驱动件包括手动笔杆、电动笔杆和智能臂。
结合上述实施例，本发明提供的一种纹绣针头及纹绣装置相比现有技术具有如下优势：
1.本发明提供的纹绣针头在使用过程中针刺部的多个针齿尖端间距稳定、互不触碰，不会发生弹性震荡导致色料飞溅，减少色料污染和清洁频次，解决了现有技术中的一个或多个问题。
2.本发明提供的纹绣针头于针刺部的针齿尾端上设置有基板，该基板形成纹绣针头的深度限位板，使用本发明所述的纹绣针头进行纹绣时，下针过程中可有效通过结构控制破皮深度，避免入刺过深，导致色料和血液混合发生变色，并蔓延到非需上色区域，提高了上色区域和色彩呈现的准确性。
3.本发明所述纹绣针头通过基板形成结构限位，可避免入刺过深发生弯折，减少皮肤损伤，提高有效上色效率，缩短修复期，降低感染率提高留色率，且通过准确限定入刺深度控制了留色代谢周期，满足了市场对不同留色期长短的需求。
4.本发明所述纹绣针头的导流柱上设置有毛细储液单元，其相比现有的纹绣针头吸墨储墨能力能更强，可长时间供墨，降低空针率。
5.应用本发明所述的纹绣针头完成纹绣后，对破皮的关键部件可进行功能性损毁，减少误伤并杜绝重复使用，提高了工具的安全性和环保性。在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多 个实施例或示例中以合适的方式结合。此外，本领域人员可以将本说明书中描述的不同实施例或示例进行接合和组合。
