所述外壳11上设置有安装结构15，所述安装结构15用于与水箱上的相关结构进行连接，所述安装结构15包括按压部151和卡接部152， 所述按压部151构造为长形板状结构。所述外壳11上形成有用于对所述安装结构15进行避让的避让孔112，所述按压部151的第一端连接到所述外壳11的第二端，所述按压部151的第二端为自由端，使所述按压部151构成悬臂梁结构，所述按压部151与所述外壳11的轴线平行并与所述避让孔112对应的设置，通过按压所述按压部151能够使其远离其第一端的部分向所述外壳11的径向内侧移动。所述卡接部152构造为形成在所述按压部151在所述外壳11径向外侧的面上的凸起结构，设置在靠近所述按压部151第一端，并距离其第一端一定距离的位置，使得所述卡接部152能够随着所述按压部151移动，向所述外壳11的径向内侧发生一定量的位移。所述卡接部152与设置在水箱上的卡扣结构进行卡接，并通过所述卡接部152向所述外壳11的径向内侧移动使所述卡接部152与水箱上的卡扣分离(下文详细介绍)。优选地，所述卡接部152靠近所述按压部151的第一端的面构造为斜面，通过所述斜面对卡接过程实现导向，以方便与水箱上的卡扣实现卡接。安装结构15设置有一个或多个，在本实施例中，所述安装结构15相对的设置有两个。
优选地，所述外壳11上还设置有限位结构，所述限位结构与所述水箱上的卡扣配合使加湿器过滤装置安装时，所述过滤支架1不能够沿其周向转动。具体地，所述限位结构包括在所述外壳11上设置所述安装结构15的位置形成的限位块16，优选地，在所述安装结构15的两侧均设置限位块16，两个所述限位块16构成所述限位结构，在两个所述限位块16之间形成限位空间，安装时，所述卡扣位于两个所述限位块16之间的限位空间内。优选地，每个所述安装结构15均对应一个所述限位结构。或者，在其他实施例中，所述限位结构还可以与水箱上的其他结构配合进行限位，例如，在水箱上设置与其配合的限位柱之类的结构。
本发明还提供一种加湿器，所述加湿器包括水箱和底座。如图3所示，所述水箱3上的出水口处设置有所述加湿器过滤装置，所述水箱3的出水口处设置有卡扣31，所述卡扣31构造为向所述水箱3的内侧延伸形成的长形结构，所述卡扣31上形成有与所述卡接部152实现卡接的卡钩，所述卡扣能够与所述卡接部152进行钩接，安装到位时，所述外 壳11的第二端部与所述水箱3的内壁抵接，并形成密封接触。安装时，所述卡扣31位于两个所述限位块16之间，即对所述加湿器过滤装置进行限位，又对其安装进行导向。当需要拆卸所述加湿器过滤装置时，按压所述按压部151能够使所述卡接部152向所述外壳11的径向内侧发生位移，从而使所述卡接部152与所述卡扣31分离，然后所述加湿器过滤装置即可以与所述水箱3分离。
本发明提供的加湿器过滤装置通过卡接的方式安装到水箱上，使其安装过程更加方便。且过滤支架的结构使滤网位于过滤支架内部，并通过过滤支架与水箱连接，使加湿器过滤装置的整体结构更加简单。
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。
