本发明提供的加湿器，在水箱的出水口处设置过滤装置，以对进入到出水阀结构的水进行过滤，防止异物进入出水阀结构对其密封性能造成影响。并且，出水阀结构设置为具有多重密封的结构，可以进一步保证密封的可靠性，避免水箱内的水大量流入到水槽内造成水槽内的水溢出。水位检测装置的设置又使得加湿器具有防止水位过低造成干烧的功能，进一步提高了加湿器使用的可靠性。
综上，本领域技术人员容易理解的是，在不冲突的前提下，上述各有利方式可以自由地组合、叠加。
以上所述仅为本发明的实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
