所述安装部14为板状，如图3所示，所述板状的安装部14上设置有定位孔141，所述电器包括壳体3，所述壳体3的内侧壁上设置有定位柱31，如图2所示，所述开关1通过所述定位柱31和所述定位孔141的配合预定位在所述壳体3上，以方便所述开关1的安装。
在定位柱31的外侧壁上设置有加强筋311，如图2所示，所述加强筋311的一侧连接所述定位柱31，所述加强筋311的另一侧连接所述壳体3的内侧壁，如此，使得所述定位柱31的安装强度可靠。
所述壳体3的内侧壁上设置有安装柱32，如图2所示，所述安装柱32与所述壳体3的内侧壁优选呈90度设置，所述安装柱32和所述定位柱31设置在所述壳体3的同一内侧壁上，所述安装柱32上优选设置有螺纹孔321，所述安装部14上设置有安装孔142，如图3所示，优选地，所述安装孔142和所述定位孔141设置在所述壳本体12的两侧，预定位在所述壳体3上的开关1通过同时设置在所述安装柱32的螺纹孔321和安装孔142上的紧固件固定在所述壳体3上。
所述安装柱32的外侧壁上设置有加强筋322，如图2所示，所述加强筋322的一侧与所述安装柱32的侧壁相连，所述加强筋322的另一侧与所述壳体3的内侧壁相连，如此，使得所述安装柱32的安装强度可靠。
所述壳体3上设置有通孔33，如图1、图2和图5所示，所述通孔33位于所述定位柱31和所述安装柱32限定的区域中，所述开关1设置成所述弹片11的第二部分113面向所述通孔33，所述按压部21构造为设置在所述可拆卸件2上的凸起211，在所述可拆卸件2处于安装状态时，所述凸起211能够穿过所述通孔33作用在所述弹片11上，进而使得所述开关1处于导通状态，所述开关1将电器内部的电路导通，所述电器正常工作，在所述可拆卸件2处于拆卸状态时，所述弹片11优选在偏置件16作用下使得所述开关1处于断开状态，所述开关1将电器内部的电路断开，所述电器断电无法工作，安全性提高。
在一个优选的实施例中，所述电保护结构包括按钮4，如图1和图4所示，所述按钮4可滑动的设置在所述通孔33中，在装配状态下，所述凸起211通过按压所述按钮4作用在所述弹片11上，在拆卸状态下，显然，所述开关1的弹片11在弹簧的弹性下可以推动所述按钮4在所述通孔33内滑动，进而使得所述开关1的弹片11处于完全的释放状态，保证所述开关1的使用可靠性。优选地，所述按钮4包括管状结构41和设置在所述管状结构41的一端的外延结构42，所述外延结构42优选设置在所述管状结构41的整个周向上，如图4和图1所示，所述壳体包括凸柱结构331，所述通孔33优选设置在所述壳体3的凸柱结构331上，在使用状态下，所述外延结构42的一侧端面能够与所述弹片11相互作用，所述外延结构42的另一侧端面能够作用在凸柱结构331的端面上，当所述开关1的弹片11作用所述按钮4并使得所述按钮4沿所述通孔33滑动时，所述外延结构42的另一侧端面能够作用在凸柱结构331的端面上，进而避免所述按钮4滑出所述通孔33，造成所述设备故障。
所述可拆卸件2为设置在所述壳体3上的盖板22或者过滤网或者湿帘组件，所述盖板22或者所述过滤网或者所述湿帘组件和所述壳体3之间可拆卸连接。
所述盖板22的内侧设置有卡扣221，如图6所示，所述壳体3的外 侧设置有与所述卡扣221配合的卡槽34，如图5所示，所述盖板22通过所述卡扣221和所述卡槽34的配合安装在所述壳体3上，所述盖板22和所述壳体3之间实现卡扣连接，卡扣连接使得所述盖板22和所述壳体3之间的连接方便可靠。可以理解，所述盖板22的内侧也可以设置成卡槽，所述壳体3的外侧对应的设置成与所述卡槽配合的卡扣，如此，所述盖板22和所述壳体3之间也可以实现卡扣连接，进而使得所述盖板22和所述壳体3的连接方便可靠。
所述壳体3的外侧底部设置有向外侧凸出的凸部35，如图5所示，所述凸部35上设置有槽/孔结构351，“/”的意思是槽结构或者孔结构351，所述盖板22的底侧设置有与所述槽/孔结构351配合的柱结构222，如图6所示，所述盖板22通过卡扣221和卡槽34的配合与所述槽/孔结构351和柱结构222的配合安装在所述壳体3上，安装时，先将所述槽/孔结构351和柱结构222装配，再将所述卡扣221和所述卡槽34装配，进而实现所述盖板22和所述壳体3的快速可靠连接。优选地，所述盖板22上的卡扣221或者卡槽设置在所述盖板22的上部，所述壳体3上的与所述盖板22的卡扣221或者所述卡槽配合的卡槽34或者卡扣设置在所述壳体3的相应位置，所述凸起211设置在所述盖板22的上部，这样可以在将所述盖板22按压安装在所述壳体3上时，所述凸起211才推动所述按钮4作用所述开关1的弹片11，实现进一步增加所述设备的安全性。可替换地，所述凸部35上可以设置成向上突出的柱结构，所述盖板22的下侧设置有槽/孔结构，如此，所述盖板22和所述壳体3之间也可以实现通过卡扣221和卡槽34的配合与所述槽/孔结构351和柱结构222的配合安装在所述壳体3上，并使得所述盖板22和所述壳体3之间的连接快速可靠。
