背景技术
含有大颗粒的液体笔类产品得到快速的发展，如珠光笔、彩色笔等，目前产品导液及储液方式很多，多数以树脂纤维作为引液部件连接涂抹头配合储液部使用，由于树脂纤维孔隙较小、分布随机且不是直通孔隙，使用过程中引液部件容易被大颗粒固体堵住，造成严重过滤及出液困难，致使液体使用效率低，另外多数大颗粒固体比重大于水，造成储液部内沉淀、成团等问题，致使出液不稳定。
实用新型内容
本实用新型提供一种引液元件及具有该元件的液体笔，针对传统液体笔的引液部件过滤和堵塞的缺点，以及储液部内大颗粒沉降、成团、释放不稳定等问题，解决了传统的液体笔不能解决的大颗粒过滤、堵塞、沉降、释放等问题，并增强了液体笔的抗泄漏能力，提高了液体笔类的可延展性以解决现有技术中的上述不足之处。

一种包含引液元件的液体笔，所述液体笔还包括储液部，所述储液部包括壳体及储液体，所述引液元件与储液体连接。
优选的，所述储液体设置有轴向孔。
优选的，所述储液体设置为第一储液体及第二储液体。
在上述技术方案中，本实用新型提供的技术效果和优点：
1、本实用新型通过在引液套内壁设置内毛细缝，且引液套内壁在内毛细缝结束的位置处设置套孔，用以支撑插设导液件，因内毛细缝具有一定的毛细力，使液体更容易从引液套的一端引向另一端，毛细缝还可以减轻液体在引流过程中的过滤及堵塞，使液体中的大颗粒可以更稳定可靠的呈现，而设置套孔，一方面防止内毛细缝直接贯通至出液端造成泄漏，另一方面对导液件起导向及固定作用，防止导液件因部分嵌入内毛细缝，致使露出部分有变形、开叉等问题，影响正常使用；

具体实施方式
为了使本领域的技术人员更好地理解本实用新型的技术方案，下面将结合附图对本实用新型作进一步的详细介绍。
实施例1
本实用新型提供了如图1-4所示的一种引液元件，包括引液套1和导液件2，所述导液件2插设于引液套1的内部，所述引液套1内壁分布有多组沿引液套1轴向设置的内毛细缝12，内毛细缝12靠近出液端11的一端设置为闭口，即在内毛细缝12在靠近出液端11处结束，不延伸至出液端11，且引液套1内壁在内毛细缝12结束的位置处设置套孔13，用以支撑插设导液件2，由于内毛细缝12具有一定的毛细力，使液体更容易从引液套1的一端引向另一端，毛细缝还可以减轻液体在引流过程中的过滤及堵塞，使液体中的大颗粒可以更稳定可靠的呈现，而设置套孔13，一方面防止内毛细缝12直接贯通至出液端11造成泄漏，另一方面对导液件2起导向及固定作用，防止导液件2因部分嵌入内毛细缝12，露出部分有变形、开叉等问题，造成使用效果不理想。
进一步的，在上述技术方案中，出液端11，指引液套1两端其中出液一端的顶面，对应的另一端面可根据出液要求贯通或不贯通，套孔13，指内毛细缝12未贯通的引液套1内壁部分所连接的与导液件2配合的通孔。
进一步的，在上述技术方案中，引液套1包括内毛细缝12的部分与包括套孔13的部分可以一体成型，也可以两部分分别成型组合使用。
实施例2
如图5-6所示，引液套1的外壁可依据出液量大小、抗泄漏要求等开设或不开设贯通槽14，且贯通槽14的位置可以依据要求调整，贯通槽14可以位于引液套1远离出液端11一端的侧壁中，并以圆周分布的形式设置为单个或多个，也可以将贯通槽14以单个或多个的形式设置在引液套1的中部。
进一步的，在上述技术方案中，当开设贯通槽14时，贯通槽14贯通引液套1的内外壁，使引液套1内外部的液体可以互通，当内毛细缝12供液不足时，外部的液体可通过贯通槽14及时补充，当引液元件内部液体充盈时，贯通槽14可及时泄压，把内部的部分液体引流至外部。
实施例3
如图7-11所示，引液套1外壁还可开设不同形状的外毛细缝15，外毛细缝15可以设置为沿引液套1轴向分布的多组条形缝，也可以设置为沿引液套1周向分布的多组横向条形缝。
进一步的，在上述技术方案中，设置外毛细缝15后，与内毛细缝12及贯通槽14配合使用，增加引流效果、增加抗泄漏性。
实施例4
如图12-15所示，一种液体笔，包括储液部3，所述储液部3包括壳体4及其内部的储液体5，所述引液元件与储液体5连接，使液体可以从储液体5导入引液元件中。
进一步的，在上述技术方案中，如图12-22所示，储液体5可分为两部分密度不同且一体成型，可两部分密度相同且一体成型，也可分为第一储液体51及第二储液体52单独成型并组装使用，且第一储液体51及第二储液体52可分别设置内外密度不同，液体笔的引液元件与储液体5连接，通过调节第一储液体51与第二储液体52的密度、材质，控制储液体5内液体的聚集区域，使液体释放更可控。
进一步的，在上述技术方案中，如图14和17所示，储液体5还可开设轴向孔配合引液元件侧面引液。
进一步的，在上述技术方案中，如图18-22所示，第一储液体51与第二储液体52的相互位置根据配合需求可作调整。
进一步的，在上述技术方案中，如图12所示，储液体5不分第一储液体51及第二储液体52、不设置轴向孔均可与引液元件连接并正常使用。
实施例5
进一步的，在上述技术方案中，如图15所示，储液部3可分为上下两部分。其中储液部3的上部分，液体笔的储液体5与引液套1外壁连接，引液套1开设有贯通槽14，当引液元件内部充盈时，液体通过贯通槽14进入储液体5，当引液元件内部液体不足时，储液体5内的液体可及时补充，达到出液稳定、不断液的效果。储液部3的下部分腔体内可根据需求设置储液体或不设储液体。
工作原理：通过在引液套1内壁设置内毛细缝12，且引液套1内壁在内毛细缝12结束的位置处设置套孔13，用以支撑插设导液件2，由于内毛细缝12具有一定的毛细力，使液体更容易从引液套1的一端引向另一端，毛细缝还可以减轻液体在引流过程中的过滤及堵塞，使液体中的大颗粒可以更稳定可靠的呈现，而设置套孔13，一方面防止内毛细缝12直接贯通至出液端11造成泄漏，另一方面对导液件2起导向及固定作用，防止导液件2因部分嵌入内毛细缝12，露出部分有变形、开叉等问题，影响正常使用；同时，通过在引液套1的外壁开设贯通槽14，以及在引液套1外壁设置外毛细缝15，贯通槽14贯通引液套1的内外壁，使引液套1内外部的液体可以互通，当内毛细缝12供液不足时，外部的液体可通过贯通槽14及时补充，当引液元件内 部液体充盈时，贯通槽14可及时泄压，把内部的部分液体引流至外部。
以上只通过说明的方式描述了本实用新型的某些示范性实施例，毋庸置疑，对于本领域的普通技术人员，在不偏离本实用新型的精神和范围的情况下，可以用各种不同的方式对所描述的实施例进行修正。因此，上述附图和描述在本质上是说明性的，不应理解为对本实用新型权利要求保护范围的限制。
