注墨后的注液笔在使用时， 贮液管 6的封水珠 66回落至隔挡壁 123的凸起 间腔体 12所述开孔 1233的一侧， 使得贮液管 6中的墨水只能向下侵润， 能有 效防止贮液管 6中的墨水因注液量过大引起的滴漏现象； 同时， 包覆在笔芯 42 周围吸水体 38中的墨水通过第二固定连接件 36中部开设的盲孔 37持续的对笔 头 41供墨， 防止了断流现象的发生。 注液笔在不使用时， 将注液笔具有笔头 41 的端部朝上放置， 笔头 41中的墨水通过盲孔 37回流至吸水体 38上， 可以对墨 水的流向起到緩沖的作用。
注液笔在不使用时， 盖紧笔帽 7 , 笔帽 7的环状壁面 74挤压芯座 3位于笔 项 2腔体外部壁面的端部使其沿笔杆 1轴线方向发生位移， 芯座 3挤压封水部 144, 封水部 144将隔挡壁 123上开设的开孔 1233封闭， 封水部 144端部边缘 贯通开设的贯通孔 1442贴合在笔杆 1隔挡壁 123上的平整平面上， 水气通道封 闭， 笔内的墨水处于锁定的状态， 不会发生滴漏的现象， 结构筒单， 操作方便。
以上所揭露的仅为本发明较佳实施例而已， 当然不能以此来限定本发明之 权利范围， 因此依本发明权利要求所作的等同变化， 仍属本发明所涵盖的范围。
