在具体实施时，所述插接口1102的内径大于所述输水通道110的内径，所述插接口1102的外径沿着背离所述输水通道110的方向逐渐收缩形成圆锥台面结构。
如图2和图3所示，所述输水通道110的靠近其出水端的外侧壁上具有一进气槽112，所述进气槽112与所述笔项12抵接形成一进气通道，所述进气通道与外部空气相连通。通过设置所述进气槽112和所述进气通道，能将外部空气导入，利用空气的压力使所墨水能均匀流畅的下滴。
具体地，所述进气通道具有一进气孔，所述进气孔用于所述进气通道与外界大气的连通。在本实施例中，所述进气孔形成于所述进气槽112上。
具体地，所述进气槽112或所述进气通道整体呈沿着所述输水通道110轴向方向的延伸的趋势。
如图2、图3以及图5所示，所述进气槽112包括多个间隔设置的环形凹槽1121和与所述环形凹槽1121相互间隔设置的连通凹槽1122；其中每一连通凹槽1122与其相邻的所述环形凹槽1121相连通，以形成所述进气槽112。
通过采用所述环形凹槽1121和连通凹槽1122结构，能增加所述进气槽112和进气通道的气密性，以使墨水快速稳定流动。此外，所述环形凹槽1121还具有储存墨水的功能。一般而言，所述储墨器3内的墨水通过进气槽112渗透出来的极少，但水性笔所处环境的气压发生较大变化，储墨器3内的墨水会外流，若没有环形凹槽1121，墨水会依次通过进气槽112及进气孔渗漏出来，环形凹槽1121的存在使得水器11上形成了一个的存储空间，墨水会被储存在环形凹槽1121内，不会外漏到水性笔外，不会弄脏使用者的手。
在具体实施时，靠近所述进气口附近的多个所述连通凹槽1122相互错位设置，能进一步防止墨水会经水器11和笔项12之间的空隙流动到笔外。
如图3所示，在本实施例中，每一所述环形凹槽1121环设与所述输水通道110的外侧壁上，所述连通凹槽1122沿着所述输水通道110的轴向延伸设置。具体地，所述连通凹槽1122形成于所述环形凹槽1121的侧壁上，用于实现相邻所述环形凹槽1121之间或所述环形凹槽1121与外界大气之间的连通。
在具体实施时，所述进气孔能通过将所述进气槽112对应近所述笔项12的端部处设置为一所述连通凹槽1122来实现，即上述通过所述连通凹槽1122实现所述环形凹槽1121和外部空气的连通。
其中，所述环形凹槽1121与所述连通凹槽1122均设置于所述输水通道110的外侧壁上，也就是说，所述进气槽112并未镂空或贯穿所述输水通道110的侧壁。
如图2、图4以及图5所示，所述输水通道110的侧壁上还开设一侧通槽113，所述侧通槽113与所述输水通道110、所述进气槽112以及所述储墨器3相连通。具体地，所述侧通槽113用于所述进气槽112与所述储墨器3之间的连通，以及所述输水通道110与所述储墨器3之间的连通。也就是说，经由所述进气通道进入的外部空气能经由所述侧通槽113进入所述储墨器3中，所述储墨器3中的墨水能经由所述侧通槽113进入所述输水通道110内。
如图2、图4以及图5所示，所述侧通槽113穿透所述输水通道110的侧壁，并且所述侧通槽113包括一第一通槽段1131和一第二通槽段1132。所述第一通槽段1131位于所述插接管1101的侧壁上用于实现所述储墨器3与所述输水通道110的连通。所述第二通槽段1132与所述第一通槽段1131相连通并延伸至所述进气槽112，并且所述第二通槽段1132用于所述进气槽112和所述侧通槽113的连通。
在具体使用时，外部空气由进气通道进入后，经所述侧通槽113进入所述储墨器3内；在外部空气的压力作用下，储墨器3内的墨水会下滴，然后经所述侧通槽113进入所述输水通道110内。
具体地，在所述第二通槽段1132的外侧壁上沿着其轴向方向间隔设置多个凹槽。具体地，每一所述凹槽沿着所述第二通槽段1132的外侧壁的周向方向延伸。所述凹槽可用于存储墨水。
本申请所述水笔还包括一笔杆，所述笔杆套设于所述笔芯外围。通过设置笔杆方便握持。
本申请水性笔通过对水器11进行改进设计，能显著提高其稳定性和气密性；本申请所述水器11通过设置输水通道110、进气槽112及侧通槽113能分别形成允许墨水流动的输水通道110和允许外界空气进入的进气通道，从而 能实现对储墨器3内墨水下滴速度的控制，达到均匀流畅的出墨效果；本申请所述进气通道气密性好，能减少外界环境对水性笔的出墨稳定性的影响，还能减少墨水的浪费并提高墨水的耐干性。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
