参照图1-图10所示，本发明的一种可拆卸电器电保护结构，在电器处于拆卸状态时实现电保护。所述电器例如可以是冷风扇，所述电保护结构包括接近开关1，所述接近开关1串联到所述电器内部的电路上，所述接近开关1包括磁控元件(图中未示出)，所述电保护结构包括设置在所述电器上的可拆卸件2，所述可拆卸件2上设置有磁性元件4。所述可拆卸件2处于安装状态时，所述磁性元件4靠近所述磁控元件使得所述接近开关1处于导通状态，所述可拆卸件2处于拆卸状态时，所述磁性元件4远离所述磁控元件使得所述接近开关1处于断开状态，所述可拆卸件2处于拆卸状态时，所述接近开关1将电器内部的电路关闭，所 述电路关闭例如可以是使得整机不工作或者使得电机不工作，进而避免了安全事故，提高了可拆卸电器电保护结构的安全性。
所述接近开关1包括安装部11，如图4所示，用于固定所述接近开关1，所述接近开关1设置在壳体3的风道35处，所述接近开关1还包括本体12，所述安装部11位于所述本体12的一侧，所述本体12的一侧设置用于与所述电器内部的电路连接的接线13，如此，当所述接近开关1安装在所述电器的内部后，可以实现和电器内部的电路连接。
所述安装部11为板状，如图4所示，所述板状的安装部11上设置有定位孔111，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3所示，所述接近开关1通过所述定位柱31和所述定位孔111的配合预定位在所述壳体3上，以方便所述接近开关1的安装。
在定位柱31的外侧壁上设置有加强筋311，如图3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3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11上设置有安装孔112，如图4所示，优选地，所述安装孔112和所述定位孔111设置在所述本体12的一侧，预定位在所述壳体3上的接近开关1通过同时设置在所述安装柱32的螺纹孔321和安装孔112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3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。
所述可拆卸件2上设置有凹槽21，如图5-图8所示，所述磁性元件4设置在所述凹槽21中，如图1和图2所示，所述凹槽21优选设置成开口向上，所述磁性元件4从如图5的上方往下装入所述凹槽21中，所述凹槽21优选设置在所述可拆卸件2的顶部，如此，更方便安装所述磁性元件4。
所述凹槽21的侧壁上设置有沿所述磁性元件4的插入方向延伸的筋 条211，如图6和图7所示，所述磁性元件4的插入方向指从上往下，筋条211用于在所述凹槽21的周向上对所述磁性元件4进行限位，如图1所示，所述筋条211的靠近所述凹槽21的开口处的一端设置成斜面2111，如图7所示，沿所述磁性元件4的安装方向，所述斜面2111逐渐从所述凹槽21的外部向内部倾斜，如此，在所述磁性元件4安装在所述凹槽21的过程中，所述斜面2111对所述磁性元件4的安装进行导向，进而使得所述磁性元件4的安装更加方便快捷。
所述凹槽21的侧壁上设置有限位结构212，如图5-图7所示，用于在所述磁性元件4的插入方向上对所述磁性元件4进行限位，进而避免所述磁性元件4从所述凹槽21中出来，保障所述接近开关1的可靠工作。
在一个具体的实施例中，所述凹槽21的与所述接近开关1相对的侧壁上设置有孔213，如图6和图7所示，所述限位结构212包括弹性止挡结构，所述弹性止挡结构的一端设置在所述孔213上方的所述凹槽21上，另一端为自由端并向下延伸，所述弹性止挡结构包括向所述凹槽21的内侧延伸的止挡部2121，当所述磁性元件4插入所述凹槽21时，挤压所述弹性止挡结构使所述弹性止挡结构向远离所述凹槽21的方向摆动，即，将所述弹性止挡结构向孔的方向挤压，当所述磁性元件4安装到位时，所述弹性止挡结构在自身弹力下复位，使得所述止挡部2121的至少一部分位于所述磁性元件4的上方，如图1所示，如此，所述磁性元件4无法从所述凹槽21的开口处出来，进而使得所述可拆卸件2处于安装状态时，所述接近开关1能够使得所述电器内部的电路正常可靠运行，不会因所述磁性元件4和所述接近开关1之间的磁感应断开而导致所述电器内部电路未接通，进而使得所述电器无法正常工作。优选地，所述弹性止挡结构还包括连接部2122，所述连接部2122的一端与所述凹槽21相连，另一端与所述止挡部2121相连，所述连接部2122的内侧设置有加强部2123，所述加强部2123能够增加所述弹性止挡结构的弹性和强度。
所述可拆卸件2的内侧设置有卡扣221，如图5所示，所述壳体3的外侧设置有与所述卡扣221配合的卡槽33，如图9所示，所述卡槽33由相对设置的两个卡件331形成，如图10所示，在安装状态下，所述卡 扣221嵌入两个所述卡件331之间，优选地，每个所述卡件331相对另一个所述卡件331的一侧面上都设置有凸出部3311，以使得所述卡扣221和所述卡槽33之间的卡接更加可靠。所述可拆卸件2通过所述卡扣221和所述卡槽33的配合安装在所述壳体3上，所述可拆卸件2和所述壳体3之间实现卡扣连接，卡扣连接使得所述可拆卸件2和所述壳体3之间的连接方便可靠。可以理解，所述可拆卸件2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，所述可拆卸件2和所述壳体3之间也可以实现卡扣连接，进而使得所述可拆卸件2和所述壳体3的连接方便可靠。
所述壳体3的下部呈框型结构34，如图9所示，所述框型结构34的下框上设置有槽/孔结构341，“/”的意思是槽结构或者孔结构341，所述可拆卸件2的底侧设置有与所述槽/孔结构341配合的柱结构222，如图8所示，所述可拆卸件2通过卡扣221和卡槽33的配合与所述槽/孔结构341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341和柱结构222装配，再将所述卡扣221和所述卡槽33装配，进而实现所述可拆卸件2和所述壳体3的快速可靠连接。优选地，所述可拆卸件2上的卡扣221或者卡槽设置在所述可拆卸件2的中上部，所述壳体3上的与所述可拆卸件2的卡扣221或者所述卡槽配合的卡槽33或者卡扣设置在所述壳体3的相应位置，所述磁性元件4设置在所述可拆卸件的上部，这样可以使得所述磁性元件4在将所述可拆卸件2按压安装在所述壳体3上时最后靠近所述接近开关1，进而使得所述接近开关1接通所述电器内部的电路，进一步增加所述电器的安全性。优选地，所述下框上设置有凹部342，如图9所示，所述槽/孔结构341设置在凹部342处，如此，一方面方便结构的定位，另一方面，当槽/孔结构341设置为孔时，还方便落入凹部342内的水由孔排出。
所述可拆卸件2为设置在所述壳体3上的湿帘组件22，所述湿帘组件22和所述壳体3之间可拆卸连接。
所述湿帘组件22包括湿帘支架223和设置在所述湿帘支架223上的湿帘224，如图5所示，所述湿帘支架223上设置所述柱结构222，如图8所示，将所述柱结构222构造成管状，用于防止流入所述湿帘224的 水溅出，如此，所述柱结构一方面使得所述湿帘支架223和所述壳体3之间可靠的连接在一起，另一方面避免了流入所述湿帘224的水溅出，消除了溅水噪音，避免设置两个结构，使得所述湿帘支架223的结构更加简单。
所述湿帘支架223上设置有挡片36和挡筋37，如图5和图8所示，所述挡片36设置在湿帘支架223的两侧，所述挡筋37设置在湿帘支架的下侧，所述湿帘224通过所述挡片36和挡筋37安装在湿帘支架223上。
