具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面对本发明中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下，所获得的所有其他实施例，都属于本发明保护的范围。
以下将结合附图对本发明进行详细说明，如图1所示：本实施例的墨水笔，包括笔头1、笔杆3以及用于控制书写出墨及封闭墨水的笔基2，所述笔头1通过所述笔基2与所述笔杆3相连，所述笔杆3内设有储墨管4，所述储墨管4上 设有注墨开口41。
其中，注墨开口41可以设置在储墨管4的侧面或者顶部，储墨管4和笔杆3可以是一体成型，也可以是分体式结构。对上述结构的修改均在本发明的保护范围内。吸墨水时，将墨水注射器放入注墨开口41就可直接完成墨水笔的吸墨，操作简单、方便。
其中，笔基2包括外壳20、与笔头1相连的导墨管21以及设于导墨管21顶端的活塞22，所述外壳20套设在所述导墨管21、活塞22和储墨管4外，并与笔杆3相连，储墨管4可相对于外壳20上下滑动，导墨管21通过活塞22与储墨管4相连通或断开。具体如图2a～2b所示，活塞22的半径大于储墨管4的半径，上下移动储墨管4可以上下活动打开活塞22。需要注入墨水时，如图2a向下移动储墨管4，关闭活塞22注入墨水，防止墨水流出。此后如图2b，向上移动储墨管4，打开活塞22，墨水流入导墨管21。
当然，笔基2也可以如图3a～3b所示，其与图2a～2b的不同在于，活塞22的半径小于储墨管4的半径，上下移动储墨管4可以上下活动打开活塞22。需要注入墨水时，如图3a向上移动储墨管4，关闭活塞22注入墨水，防止墨水流出。此后如图3b向下移动储墨管4，打开活塞22，墨水流入导墨管21。
需要说明的是，上述操作中，需要先关闭活塞22，再注入墨水，如果不先关闭活塞22就注入墨水，墨水会直接从笔头1流走。而加完墨水后关闭笔盖5再打开活塞22，由于没有与大气压连通，进而能防止墨水流走。
作为上述技术方案一个较佳的实施方式，如图1所示：注墨开口41设置在所述储墨管4顶部，所述注墨开口41边缘设有密封圈42，所述笔杆3顶部转动连接有笔盖5。具体的，笔杆3可与笔盖5铰接，或者笔杆3与笔盖5采用塑料材料制成一体式转动连接。
作为上述技术方案一个较佳的实施方式，注墨开口41设置在所述储墨管4顶部，所述注墨开口41边缘设有密封圈42，通过密封圈42可以将墨水密封在储墨管4内，防止墨水流出。所述笔杆3顶部外表面与笔盖5内表面设有匹配的螺纹，笔杆3与笔盖5通过该螺纹连接。
作为上述技术方案一个较佳的实施方式，如图4所示：所述储墨管4顶部设有注墨开口41，所述储墨管4与所述笔杆3为一体成型，所述笔杆3顶部设有可拆卸的笔盖5。具体的，所述储墨管4的长度与所述笔杆3的长度相同，所述注墨开口41连接有注墨管43，所述笔盖5可拆卸的套设在所述注墨管43上。
作为上述技术方案一个较佳的实施方式，如图5所示：所述储墨管4顶部设有注墨开口41，所述储墨管4与所述笔杆3为一体成型，所述笔杆3顶部设有可拆卸的笔盖5。具体的，所述储墨管4的长度与所述笔杆3的长度相同，所述注墨开口41连接有注墨管43，所述注墨管43上设有可拆卸的注墨管塞44。通过注墨管塞44可以将墨水密封在储墨管4内，防止墨水流出。
作为上述技术方案一个较佳的实施方式，如图6a～6b所示，所述储墨管4顶部设有顶部开关阀门6，所述笔基2包括与所述笔头1相连的导墨管21以及套设在所述导墨管21下端的外壳20；所述墨水笔还包括连接笔杆31，所述连接笔杆31的一端与所述外壳20的顶部固定连接，所述连接笔杆31的另一端套接在所述笔杆3和所述储墨管4之间；所述储墨管4底部设有底部开关阀7，所述储墨管4可相对于所述连接笔杆31上下滑动，所述导墨管21通过所述底部开关阀7与所述储墨管4相连通或断开。具体地，如图6b，所述储墨管4向下滑动时，所述导墨管21穿过所述底部开关阀7，使所述底部开关阀7打开。注入墨水时，如图6a所示，打开所述顶部开关阀门6，向储墨管4注入墨水，然后关闭顶部阀门6；书写时，向下推动储墨管4，所述导墨管21穿过所述底部开关阀7，使所述底部开关阀7打开，导墨管21插入到储墨管4，墨水从导墨管2流入笔基2至笔头1。
作为上述技术方案一个较佳的实施方式，如图7a～7c所示，所述笔基2包括与所述笔头1相连的导墨管21以及套设在所述导墨管21外的外壳20，所述外壳20顶部设有进墨孔8，所述储墨管4底部设有出墨孔9，所述储墨管4可绕其轴线转动以使所述出墨孔9与所述进墨孔8错位或重叠。需要注入墨水时(如图7b所示)，转动储墨管4直至出墨孔9和进墨孔8错位形成封闭，从而墨水不能流到笔基2的导墨管21，然后打开笔盖5，从注墨开口41注入墨水；书写时(如 图7c所示)，先盖上笔盖5，转动储墨管4直至出墨孔9与进墨孔8重叠，此时墨水从储墨管4流入笔基2的导墨管21。
作为上述技术方案一个较佳的实施方式，所述储墨管4与所述笔杆3一体成型，所述笔杆3底部固设有连接头10，所述笔基2的外壳20顶部设有与所述连接头10转动配合连接的圆环导槽11，所述圆环导槽11的轴线与所述储墨管4的轴线重合。这样，就可以通过连接头10与圆环导槽11之间转动配合连接，转动笔杆3实现出墨孔9与进墨孔8错位或重叠。
需要说明的是，上述操作中，必须先使出墨孔9和进墨孔8错位形成封闭，再注入墨水，如果不先使出墨孔9和进墨孔8错位形成封闭就注入墨水，墨水会直接从笔头1流走。而加完墨水后关闭笔盖5再使出墨孔9与进墨孔8重叠，由于没有与大气压连通，进而能防止墨水流走。
本发明提供的墨水笔，通过在笔杆3上设置注墨开口41，更换墨水时，将墨水注射器放入注墨开口41就可直接完成墨水笔的吸墨，操作简单、方便。很好的解决了现有墨水笔因添加墨水繁琐而被放弃使用的问题。
本发明提供的墨水笔，相较于现有技术，具有如下有益效果：
1、现有墨水笔添加墨水麻烦，储墨量不多，墨水瓶携带不方便而且容易打碎。而本发明不但添加墨水方便、干净、量多，而且因为采用注射添加墨水，墨水瓶可以采用塑料等软体材料制成，形状也可以多样化，而且不会破碎。
2、现有墨水笔在受到振动时很容易造成墨水浸漏，携带不方便。而本发明的墨水笔中导墨管和储墨管之间可以全封闭断开，不会出现墨水浸漏的问题，携带方便。
3、本发明提供的墨水笔具有书写字体美观、耐用等优点。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
