Description

防漏墨的可重复加墨型墨水笔 技术领域
本发明涉及墨水笔领域技术，尤其是指一种防漏墨的可重复加墨型墨水笔。
背景技术
墨水笔是人们使用最多的书写工具。特别是中性墨水笔，由于书写流畅、使用方便、价位低廉等优点深受人们青睐，成为书写笔市场的主要产品。
中性墨水笔的优势在于携带方便，一般不会漏水，相对比较洁净，并且适宜快写，换笔芯比较方便。但因价格便宜等原因，大量的中性墨水笔在笔芯使用完毕后，笔杆和笔芯一起被随意丢弃，对环境造成很大危害。制造中性墨水笔的主要原料是聚苯乙烯或改性聚苯乙烯，均以耐老化、抗腐蚀著称，在大自然中基本无法降解。而未用完的中性墨水笔芯中的残余物质，包括墨水、浮脂等物质，对土壤和水质都会产生污染。
与中性墨水笔相比较，钢笔不仅可以重复使用，使用寿命长，而且不会造成环境污染，在这些方面具有较明显的优势。但是，钢笔普遍存在书写不顺畅、容易漏水、断水等弊端。
后来，有人研究了可重复加墨使用的墨水笔，如：在先专利文献CN200910185085公开了一种多功能袋式储墨笔及配套使用的注墨瓶，虽然，其意在结合钢笔与中性笔的技术优点进行创新，但是，其不适于批量生产，由于需要经常拆卸笔头注墨，笔头与储墨袋的连接密封性难以得到保证，因此，仍会存在漏墨现象。在前述CN200910185085中实际上并未提到如何确保不漏墨；若需要确保不漏墨，根据本领域技术人员目前的技术手段，也只能保证少量定制生产的前提下，来提高防漏墨性能。还有，其墨水囊也存在不可避免的缺陷，墨水囊的材质及形状类似于避孕套设计，其本身呈自然收缩状，软塌不能成型，不能均匀分布在笔杆内，自然收缩状的墨水囊给加注墨水操作也造成障碍。也就是，目前的可重复加墨使用的墨水笔，事实上，根本不适于批量生产，无法推广应用。
因此，需要研究出一种新的技术方案为解决上述问题。
发明内容
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种防漏墨的可重复加墨型墨水笔，其兼具多种书写笔的优势，可重复多次加墨使用，环保、耐用，尤其是，通过软胶开关的设置，有效避免在拆下笔头时、书写过程中以及存放、携带该墨水笔时出现漏墨现象，提高了该墨水笔的实用性，适于推广应用。

具体实施方式
请参照图1至图7所示，其显示出了本发明之实施例的具体结构。
一种防漏墨的可重复加墨型墨水笔，包括有笔杆、设于笔杆内的可重复加墨型笔芯组件、组装于笔杆下端的笔头套1；其中：
所述笔芯组件包括有墨水囊2、墨水导管3、软胶开关4及笔头5；所述墨水囊2具有可变形的内部容墨腔，其内部容墨腔具有下端开口；通常，墨水囊可以是由乳胶、聚氨酯、新型复合纳米、超级物料石墨烯等高性能材料制造，墨水囊的壁厚类似于小气球、避孕套等物件的壁厚，其耐候性好、拉伸度高，性能优异。空墨水囊呈扁平带状或自然收缩状，由于墨水囊具有弹性拉伸度，注入墨水到墨水囊中，墨水囊在墨水的压力下扩张呈圆柱状或其他膨胀状态。所述墨水导管3的上端连通于内部容墨腔的下端开口；所述软胶开关4具有上下延伸设置的可变形开合式开关孔34，所述软胶开关4上具有用于设置开关孔34的可变形阻挡壁；所述软胶开关4装设于墨水导管3的下端；所述笔头5具有下端设置的书写笔尖6和上端设置的笔尖接头7；所述笔尖接头7可拆卸式连通于软胶开关4。本实施例中，所述笔尖接头7的上段部位形成有台阶段26，即：台阶段26的上端部位、台阶段的下端部位均小于台阶段26，这样，一方面是便于笔尖接头7的装入，另一方面，笔尖接头7的台阶段26更好地撑开可变形阻挡壁，使之变形，以扩大开关孔34。
所述笔头套1可拆卸式组装于笔杆的下端，所述笔头5的书写笔尖6向下伸出笔头套1。此处，在笔头套1的内壁面凸设有两条以上的定位凸肋29，以便在笔头5穿过笔头套1内时更好地定位，笔头5不会相对笔头套1偏移晃动。
当笔头5被拆卸脱离软胶开关4后，软胶开关4的可变形开合式开关孔34处于自然状态，也可以理解为软胶开关4处于关闭状态，此处的关闭状态是指开关孔34恢复到自然状态，即下述的直径为0.05-0.50毫米之间的状态，由于墨水有张力，墨水囊2内的墨水不能经此状态下的软胶开关4溢出，但是，墨水囊2内的气体是可以经软胶开关4排出。
当笔头5被组装定位于软胶开关4的下端，所述笔头5的笔尖接头7向上抵推软胶开关4的可变形阻挡壁，开关孔随着可变形阻挡壁的向上变形而被撑大，笔尖接头7的上段部位穿过被扩大后的开关孔，笔尖接头7的外壁面与开关孔的内壁面一直保持密封式接触；笔尖接头7的上端伸入墨水导管3内，以与墨水导管3贯通；通常，墨水导管3内至少供笔尖接头7的上端伸入的部位，其孔位尺寸设计得比笔尖接头7的上端大，也就是说，当笔尖接头7的上端伸入墨水导管3内后，在笔尖接头7的上端的外围形成有让位间隙32，以用于供软胶开关4变形作让位，大致如图5所示，在软胶开关4受挤压变形后，会形成向上变形的飞边33。
软胶开关4处于打开状态（如图2和图5所示），笔尖接头7的上端一直与软胶开关4的可变形阻挡壁密封式接触，仅通过打开的可变形开合式开关孔与笔尖接头7的内部通道形成贯通，笔尖接头7与软胶开关4形成密封式导通，避免在书写过程中以及存放、携带该墨水笔时出现漏墨现象，墨水囊2内的墨水经墨水导管3、软胶开关4、笔头5溢出，此时的软胶开关4起到导流墨水作用，这样笔就可以正常书写了，书写的过程中随着墨水的不断减少也会排出墨水囊内的空气，墨水囊2部分呈自然收缩状，墨水用完了，墨水囊2就恢复成扁平带状或自然收缩状。
这时，需要加墨水到墨水囊2中；具体操作过程是：先拆下笔头套1，再拆下笔头5，利用注墨器插入软胶开关4的开关孔34，重新注入墨水到墨水囊2中，然后再装上笔头5、笔头套1，这支笔又可以书写了，如此重复加墨使用，达到了墨水笔可重复加墨使用的目的。
本实施例中的软胶开关4优选设计为硅胶材质制作，所述可变形阻挡壁的顶端具有向下凹设的凹弧面8，所述可变形阻挡壁的底端具有上小正大的锥形表面9，优选地，所述凹弧面8呈球冠状，整个可变形阻挡壁设计为中心轴对称结构，本实施例中，前述凹弧面8及锥形表面9的组合设计，并非是任意形状的选择，申请人有进行大量比对、分析、测试，该种设计具有较好的张力作用，确保在自然状态时具有很好的密闭性，防漏墨效果好。软胶开关4的可变形开合式开关孔34设计得十分小，一般直径为0.05-0.50毫米之间，考虑到制程简易性，优选0.25-0.5mm之间；开关孔34很小，墨水有张力，自然状态下，墨水不会溢出来，除非是非正常状况下用力甩笔杆，才有可能把墨水甩出来。
软胶开关4在自然状态下，由于其开关孔34很小，起到封闭墨水功能，拔掉笔头5不会漏墨；加注墨水时，由于开关孔34受注墨器的强制插入，开关孔34与注墨器的插入部是密封配合的，墨水从注墨器加注到墨水囊2中。
此处，大致总结前述软胶开关4在不同情形下的使用功能如下：
1、排气功能：墨水囊2没有装墨水时，墨水囊2的壁体受外界空气压力作用，经自然状态下的开关孔34可以自然排出墨水囊内的多余空气；
当然，在墨水囊2中有部分墨水的情形下拆卸笔头5后、加墨完成后、装上笔头后的多种情形下，都是可以通过开关孔34将墨水囊2内的多余空气排出；
2、加墨功能：拆卸笔头5后，注墨器强制插入开关孔34，可以往墨水囊2内加入墨水，加墨过程中，墨水囊2中的气体不会外排；
3、导墨孔功能：当笔尖接头7接入时，墨水囊2内的墨水经开关孔34导出墨水至笔头5以供书写使用；
4、封闭墨水功能：当墨水没有用完时，若拆卸笔头5，开关孔34会恢复至自然状态，其孔尺寸变得非常小，墨水不能从墨水囊2外溢，因此，可以起到封闭墨水功能；
软胶开关4的排气功能，可以确保墨水囊2内尽量少地存在多余空气，有利于提高墨水囊2的有效储墨水量；以及，软胶开关4的封闭墨水功能，可以起到防漏墨作用，提高该墨水笔的实用性。
本实施例中，对软胶开关4组装定位结构设计十分巧妙，其具有结构设计简单、组装方便、定位稳固、可靠性佳等诸多优势，具体描述如下：
针对所述软胶开关4设置有定位件10；所述定位件10为筒状结构，所述定位件10套于软胶开关4的外周，所述定位件10的上端连接于笔杆，所述定位件10的下段部位往内延伸有止挡台11以限位于软胶开关4的下端。所述定位件10的下段部位的外侧表面形成有第一外螺纹12，所述笔头套1的上段部位的内侧表面形成有第一内螺纹13，所述笔头套1通过第一内螺纹13可拆卸式组装于定位件10的第一外螺纹12处。所述笔尖接头7具有往外凸设的限位边14，所述笔头套1的内侧具有相应的限位台阶面15；所述限位边14适配于限位台阶面15上。所述墨水导管3的下段部位的外侧表面设置有第二外螺纹16，所述定位件10的上段部位的内侧表面设置有第二内螺纹17，所述定位件10通过第二内螺纹17可拆卸式组装于墨水导管3的第二外螺纹16处。
以及，为了使得墨水囊2在注墨水及书写使用过程中，能够保持拉直状态，本实施例中是采用内置墨水囊定位架18的方式，其主要是考虑到三个方面，其一是有助于排空墨水囊的空气，其二是有助于注入墨水，其三是有助于墨水向笔头移动，确保书写顺畅；具体结构设计为：所述墨水囊2内设置有墨水囊定位架18，墨水囊定位架18上下延伸设置且呈扁平状。如图7所示，墨水囊定位架18具有用于定位墨水囊的支撑周边27，来撑起墨水囊起到定型作用；支撑周边27之间设计为镂空区域28，这样，在墨水囊往外排墨逐渐收缩时，其排墨、排气更加彻底，可以使空墨水囊收缩为最小的扁平带状。此处，所述墨水囊定位架18的下端连接有接头管部19，接头管部19的外表面紧配式嵌套于墨水囊2的内部容墨腔的下端开口的内表面处，墨水囊2的下端设计有收口设计的窄小段24用于与接头管部19相紧配密封，也就是说，窄小段24的内壁面是套在接头管部19的外壁面上，两者紧密配合。相应地，墨水囊定位架18相较接头管部19略宽设计，墨水囊定位架18的上端支撑于墨水囊2的内部顶端，这样，墨水囊定位架18更好地支撑定位在墨水囊2的内部。所述墨水导管3的上端部位密封式伸入接头筒管部19的内部。所述笔杆包括有笔杆主体20、笔杆接头21；所述笔杆接头21具有上段结合台阶22、下段结合台阶23，笔杆主体20的下端套装于上段结合台阶22的外部，所述定位件10的上端套装于下段结合台阶23的外部。
以及，所述笔杆主体20为上、下端开口的杆状设计在笔杆主体20的上端组装有笔尾盖25，以及，通常配置有用于盖住笔头5、笔头套1的笔帽30。在笔帽30内通常设置有笔头封帽31，其主要起到保护书写笔尖6的作用。此处，对笔头封帽31的结构进行了改良设计，即：笔头封帽31优选采用硅胶等软胶制作，其截面呈H形，笔头封帽31的顶端向下凹设有上端凹位32，以及笔头封帽31的底端向上凹设有下端凹位33，这样，当笔帽30套于笔头5、笔头套1的外部时，书写笔尖6对应伸入上端凹位32处；下端凹位33的设置，主要是用于供上端凹位32的底壁受到书写笔尖6的抵压作用时产生变形。
综上所述，本发明的设计重点在于，其主要是兼具中性笔、白板笔、记号笔、美术笔、钢笔等多种书写笔的优势，可重复多次加墨使用，环保、耐用，尤其是，通过软胶开关的设置，有效避免在拆下笔头时、书写过程中以及存放、携带该墨水笔时出现漏墨现象，提高了该墨水笔的实用性，解决了传统技术中重复多次加墨使用的墨水笔所存在的漏墨问题，适于批量生产及推广应用，以真正成为惠及广大使用者的全新换代书写工具；
以及，本发明中，对该墨水笔的结构设计十分合理，确保了该墨水笔的产品质量及可批量生产性；尤其是，对软胶开关组装定位结构设计十分巧妙，其具有结构设计简单、组装方便、定位稳固、可靠性佳等诸多优势。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
