优选的，所述进液端51与进气端53为针形，且所述进液端51与进气端53的端头针尖部位距离上盖表面的距离大小范围为21-24mm。
优选的，作为对本发明的改进，所述底盖2、缸体3、阀板4与上盖之间是通过螺丝55连接。结构设计合理，连接效果好。
本发明的地拖使用自带止流功能微型水泵，进液使用的进液端51和换气使用的进气端53同时设于上盖5的上部，在上盖5侧面还设有出液管52，在上盖5的另一侧底部设有预留的可供用户端组装的空气过滤器的预留连接部54，在上述阀板48上面围绕进液孔和出液孔43设有凹陷的进液室；用于进液与出液形成单独的腔体；同时阀板4的内设有单向阀装置8，用于停泵时阻断液体通道，防止产生虹吸现象。工作时驱动马达1带动偏心轮12转动，偏心轮12推动摆架7往复运动，摆架7向下运动时，压缩室单元61由压缩状态变为舒张状态，在负压作用下，大气压通过进气端14进入空气到带有真空的密封容器中，以使密封容器中的液体从上盖5的进液端13进入阀板4通孔，此时伞形密封件41打开，液体进入压缩室；摆架7向上运动时，压缩室单元61由舒张状态变为压缩状态，压缩室单元61上部的相应的伞形密封件41封闭，导流片64打开，同时止流阀装置8在水泵自身的水压下使弹簧体82压缩，止流体81打开，液体由上盖5的出液管12排出；微型水泵在停止工作时，止流阀装置8中的弹簧体82恢复到原来的伸开状态，止流体81依托弹簧体82的自身阻力，使微型水泵的液流通道被阻断，虹吸现象得到止制。
以上所述的本发明实施方式，并不构成对本发明保护范围的限定。任何在本发明的精神和原则之内所作的修改、等同替换和改进等，均应包含在本发明的权利要求保护范围之内。
