传统的双金属片式温控器包括较为复杂的动作机构，双金属片有一定的弧度，动作推杆需与双金属片弧度匹配，生产过程非常繁琐，组装难度大。同样地，现有的磁敏温控器也与双金属片式温控器一样，有着较为复杂的动作机构，需要在硬磁体的底部设置动作推杆，利用动作推杆触发微动开关的导通或断开，为了适配动作推杆的安装，需要在硬磁体的底部开设一个盲孔，然后使动作推杆插入盲孔中，但是动作推杆和硬磁体的材料属于非弹性形变材料，尺寸加工较难，两者之间的配合间隙难以控制，配合间隙过大就容易松动，配合间隙过小又难以装配，所以导致组装非常困难。另外，这种采用动作推杆触发结构的磁敏温控器经过长期使用后，动作推杆和硬磁体会有连接松动的情况发生，产品安全性和可靠性大大降低，用户使用存在安全风险。
可见，现有技术还有待改进和提高。

具体实施方式
本发明提供一种磁敏温控器，为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明的保护范围。
请参阅图1-图3，本发明提供一种磁敏温控器，包括上端开口的外壳1，设置在外壳内腔中的内壳2，盖设在外壳上端的导热盖3，设置在内壳顶部且与导热盖导热连接的感温软磁体4，设置在内壳内腔中的硬磁体5，设置在感温软磁体和硬磁体之间的弹簧6，以及固定设置在外壳内腔中的连接电路7，以及用于接通或断开所述连接电路的动触片8；所述硬磁体5包括底座52和设置在底座上的凸台51，所述动触片8套设在凸台51上；所述硬磁体5位于感温软磁体4的下方，所述感温软磁体4和硬磁体5磁性吸合时，克服弹簧6弹力使动触片接通连接电路；所述感温软磁体4失去磁性时，弹簧6推动硬磁体5远离感温软磁体使动触片断开连接电路。
以下简述工作原理：导热盖3与感温软磁体4导热连接(即导热盖3紧贴感温软磁体4的上端面，或者在导热盖3与感温软磁体4之间的间隙中填充导热硅脂)，产品主件温度升高所产生的热量通过导热盖传递给感温软磁体，当产品主件开始加热时，感 温软磁体4的温度低于其居里温度，感温软磁体4具有磁性，感温软磁体4和硬磁体5发生磁吸作用，凸台51和感温软磁体4的底部相互吸合，带动硬磁体5克服重力和弹簧6的弹力向上移动，套设在凸台51上的动触片8也跟随凸台51向上移动，接通连接电路7。当感温软磁体4的温度逐渐升高高于其居里温度时，感温软磁体4的磁性消失，弹簧6推动硬磁体5远离感温软磁体4使动触片8断开连接电路。与现有技术相比，只需动触片8就可以控制连接电路7的导通和断开，无需使用动作推杆，结构更加简单，从根本上解决动作推杆结构存在的不足；动触片牢固套在凸台上，动触片的主体抵压在底座上，装配简单，长期使用也不会发生松脱的情况发生，保证产品安全性和可靠性。
具体的，请参阅图4，所述动触片8呈环形状，动触片8的两侧分别设有一个折耳81，每个折耳上设有一个动触点82；所述动触片8的内环设有向上折弯的翻边83，这些翻边83顶端所围成的圆周直径小于凸台51的直径。该动触片的主体、翻边、折耳由钣金加工而成，结构强度高，易于制造，无需二次装配。装配时，只需将动触片套在凸台上，直至动触片的底部抵压在底座上；由于翻边顶端所围成的圆周直径小于凸台的直径，翻边为金属薄片，具有一定的弹性形变能力，翻边对凸台形成一个径向的锁紧力，使翻边紧紧压贴在凸台的侧壁上，实现动触片的径向和轴向的定位，防止动触片长期使用发生松动，保证动触点与连接电路的触发位置准确。
进一步的，请参阅图1和图2，所述连接电路7包括固定设置在外壳上的第一端子71和第二端子72以及分别与第一端子和71第二端子72导电连接的第一静触片73和第二静触片74，第一静触片73和第二静触片74的自由端上均设有静触点75，第一静触片73和第二静触片74上静触点朝向对应的动触点82。第一静触片和第二静触片呈C字形，内壳的侧壁上开设有供静触片导入的避让口，这些静触点位于对应动触点的上方，通过这样设置，连接电路的结构紧凑，巧妙利用外壳和内壳之间的空隙，同时也减少装配难度。
优选的，请参阅图1-图3，所述第一端子71和第二端子72为插片，外壳1的底部对称设置有两个插槽11，所述第一端子71和第二端子72的内端插置到对应的插槽11中，述第一端子71和第二端子72的外端分别延伸至外壳外；第一静触片73和第一端 子71通过铆钉9连接且固定在外壳1上，第二静触片74和第二端子72通过铆钉9连接且固定在外壳1上。通过这样设置，第一端子、第二端子、第一静触片、第二静触片的定位准确，长期使用不会发生偏移，第一端子和第二端子能够再与其他电器元件进行导电连接。
优选的，请参阅图5，所述内壳2的内壁上设有一个环形的台阶21，所述内壳的内壁上向内凸起至少两个定位块22，所述感温软磁体4包括与导热盖接触的感温部41和设置在感温部底下的定位部42，所述定位部42上开设有与定位块相适配的定位槽43，每个定位块卡入在对应的定位槽43中，所述感温部41的直径大于定位部42的直径，感温部41抵压在内壳2的顶部，定位部42抵压在台阶21上。装配时只需直接把感温软磁体的定位部装入内壳的内腔中，即可完成连接，方便快捷；导热盖和台阶对感温软磁体进行轴向定位，防止感温软磁体受到磁吸作用发生移动；通过定位部和定位槽的配合防止感温软磁体在内壳内发生转动。
优选的，请参阅图2和图5，所述硬磁体5的凸台装入在台阶21的内环中，所述台阶21的下侧设有两个对称设置的限位凸块23以及多根沿周向等角度设置的第一限位凸条24，这些限位凸块23和第一限位凸条24均设置在内壳2的内壁上且竖直向下延伸设置，所述硬磁体5的底座52上设有与限位凸条相适配的凹口53。一方面限位凸起限制硬磁体转动，保证动触片上的动触点连接电路的位置准确，另一方面限位凸条可以导引硬磁体竖直上升或下降，硬磁体移动顺畅平稳。通过第一限位凸条进一步对硬磁体的底座径向活动幅度进行限制，防止晃动偏移的幅度过大。
优选的，请参阅图5，所述台阶21的内壁上设有多根沿周等角度设置的第二限位凸条25。通过设置第二限位凸条，对硬磁体的底座径向活动幅度进行限制，防止晃动偏移的幅度过大。
优选的，请参阅图2，所述凸台51的上端开设有一个用于安装弹簧6的盲孔54，弹簧6的顶端抵压于感温软磁体4的底面。当铁磁体和感温软磁体发生磁吸作用时，弹簧藏匿在盲孔中，不对凸台和感温软磁体的定位部连接造成干涉。
优选的，请参阅图2和图5，所述内壳2的上端外侧壁上设置有至少两个卡块26，所述外壳1的内壁上开设有对应的卡槽12，所述内壳2和外壳1之间通过卡块26和卡槽12径向定位。装配时，只需把内壳插到外壳的内腔即可完成连接，方便快捷；通过卡块和卡槽的配合，防止内壳在外壳内发生转动。
可以理解的是，对本领域普通技术人员来说，可以根据本发明的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本发明的保护范围。
