所述定子24嵌设于所述第二环形槽112内。在所述微型水泵100的工作过程中，所述电路板30给所述定子24通交流电，根据电磁感应原理，所述定子24产生旋转磁场，所述转子23在旋转磁场中受安培力的作用发生旋转，旋转的所述转子23带动所述叶轮22旋转。液体从所述进液口102进入所述内腔101，在所述叶轮22的推动下高速旋转并做离心运动，液体到达所述出液口103时从出液口103甩出，液体被甩出后，所述内腔101中的压强减小，远小于大气压力，外界的流体在大气压强的作用下从所述进液口102补充进所述内腔101中，重复地实现上述的动作，实现液体的输送。
本发明提供的微型水泵100，通过在所述本体部121靠近所述底座11的表面设置凹陷形成的所述收容槽122，使得所述转轴21的一端嵌设于所述底座11，另一端收容于所述收容槽122内，替代相关技术中的悬臂梁结构，增强了所述转轴21的支撑强度，提高了叶轮22的转动稳定性，同时，本发明提供的微型水泵100可以减小所述转轴21与所述上盖12之间的间隙，增强了所述微型水泵100的整体强度，跌落可靠性亦更有保障。
本领域的普通技术人员可以理解，上述各实施方式是实现本发明的具体实施方式，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本发明的精神和范围。
