优选地，在另一可实施性实施例中，还可以将所述安装结构32、出水流道12和所述出水结构13设置为一体结构，所述进水流道11与所述壳体1设置为一体结构。
如图4所示，所述出水阀结构在加湿器中使用时，所述出水阀结构安装到水箱上3的出水口处，所述水箱3安装到水槽4上，所述水箱3内的水能够通过所述出水阀结构流到所述水槽4内。优选地，所述出水阀结构的壳体1可以与所述水箱3构造为一体结构，即所述壳体1与所述水箱3一体形成。所述水 槽4内设置有浮子5，所述浮子5包括漂浮部51和驱动部52，所述漂浮部51能够随着所述水槽4内的液面上升或下降，所述驱动部52能够推动所述阀芯21向上运动。所述漂浮部51和所述驱动部52之间间隔一定距离，并通过连接部53连接，所述连接部53上形成有支点，所述支点可转动地连接到所述水槽4内，使所述浮子5构成杠杆结构，所述驱动部52构成所述杠杆结构的第一侧结构，所述第一侧结构与所述阀芯组件2对应设置能够对所述阀芯组件2提供推力，所述漂浮部51构成所述杠杆结构的第二侧结构，所述第二侧结构能够将所述出水结构13上的出水口封堵。当所述水槽4内液面较低时，所述漂浮部51的下降，所述驱动部52上升，所述驱动部52推动所述封堵盖31发生变形，从而推动所述阀芯21向上运动，使所述水箱3内的水能够流入到所述水槽4内。当所述漂浮部51随着所述水槽4内的液面上升而上升时，所述驱动部52会下将，从而使所述阀芯21下降，直至所述阀芯21运动到第一位置时，所述进水流道11被封堵，水不能继续流入到所述水槽4内，此时，所述漂浮部51的上表面与所述密封部131接触，从而能够将所述出水结构13上的出水口封闭。当所述阀芯组件2失效时，所述进水流道11不能被封堵，此时，所述水槽4内的水位会持续上升，当上升到一定位置后，所述漂浮部51与所述密封部131接触并对所述密封部131施加压力，从而使所述出水口被封堵，使水不能继续流入到所述水槽4内，避免水会溢出。
优选地，还可以在所述漂浮部51上设置密封结构，所述密封结构例如构造为密封圈、密封垫片等结构，当所述漂浮部51随着水位上升到一定的高度后，所述漂浮部51上的密封结构与所述出水结构13上的出水口接触将所述出水口封堵。此时，所述出水结构13上可以设置所述密封部131，使所述密封部131与所述密封结构配合，使密封效果更好，或者，还可以不设置所述密封部131。
如图2、5所示，在第二实施例中，所述进水流道11的第二端113为封闭端，即所述封堵部与所述进水流道11一体形成在所述进水流道11的第二端113，所述进水流道11构造为第一端112开口，第二端113封闭的管状结构。所述阀芯21的第二端212位于所述进水流道11内，所述阀芯21的第二端212设置有第一磁体24，相对应地，在该实施例中，所述浮子5的驱动部52上设置有第二磁体521，所述第一磁体24和第二磁体521能够产生排斥力，从而使得当所述驱动部52靠近所述阀芯21时，能够推动所述阀芯21向上运动，优选 地，所述第一磁性部件24和所述第二磁性部件52均为磁铁，安装时使所述第一磁性部件24和第二磁性部件52的同极相对设置。
本发明提供的出水阀结构设置出水流道，并在出水流道的端部设置出水结构，出水结构能够与水槽内的浮子配合，当水位过高时浮子可以将出水结构上的出水口进行封堵。从而使出水阀结构具有通过阀芯组件封堵进水流道和通过浮子封堵出水口的双重密封，以提高出水阀结构的可靠性。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各优选方案可以自由地组合、叠加。
应当理解，上述的实施方式仅是示例性的，而非限制性的，在不偏离本发明的基本原理的情况下，本领域的技术人员可以针对上述细节做出的各种明显的或等同的修改或替换，都将包含于本发明的权利要求范围内。
