所述绝缘连接件 20连接于所述内部加热容器 1顶部与外部加热容器 3 顶部，以绝缘所述内部加热容器 1与外部加热容器 3 ,防止二者的侧壁直接 接触引发短路。
所述数个端子 5为具有高电阻阻值的端子，其通过焊接的方式固定于 内部加热容器 1的底部。 所述数个端子 5至少为两个。 所述数个端子 5的 长度不同，且每一端子 5均未接触所述外部加热容器 3的底部。
所述电源 6与指示装置 7安装于所述内部加热容器 1顶部与外部加热 容器 3顶部之间。 所述电源 6为微型纽扣电池。 所述指示装置 7包括与该 微型纽扣电池电性连接的数个指示灯 750 所述数个指示灯 75至少为两个， 其数量与所述端子 5的数量相等。 所述数个指示灯 75为分别具有不同的初 始电流、 不同颜色的灯泡，当电流值低于该灯泡的初始电流时，电流仅从 该灯泡通过，但该灯泡不亮，当电流值达到该灯泡的初始电流值时，该灯 泡亮起。
所述数个端子 5构成并联关系，所述数个指示灯 75构成串联关系。 当 高温金属材料 9泄漏至外部加热容器 3时，一个或多个端子 5接触泄漏的 高温金属材料 9 ,导通内部加热容器 1、 外部加热容器 3、 电源 6与指示装 置 7 ,触发所述一个或多个指示灯 75亮起，从而判定高温金属材料 9发生 泄漏，且能够根据指示灯 75亮起的数量，判定泄漏的程度，提示技术人员 做出相应处理，防止高温金属材料进一步泄露。
以所述数个端子 5的数量为两个，包括第一高阻值端子 R1与第二高阻 值端子 R2 ,所述数个指示灯 75的数量为两个，包括第一指示灯 L1与第二 指示灯 L2为例，来说明本发明侦测和防止高温金属材料泄漏的加热装置的 工作过程。
设第一高阻值端子 R1的长度大于第二高阻值端子 R2的长度，第一指 示灯 L1的初始电流为 II,第二指示灯 L2的初始电流为 12 ,且 12大于 II。 该加热装置工作时，对所述外部加热容器 3进行加热，同时内部加热容器 1 通过热传导与热辐射的方式接收热量，加热其盛装的金属材料 9直至所述 金属材料 9熔融、 蒸发。 请参阅图 4、 图 5 ,当所述内部加热容器 1完好、 未产生微裂纹，受热后的高温金属材料 9未发生泄漏的情况下，所述内部 加热容器 1、 夕卜部加热容器 3、 数个端子 5、 电源 ό与指示装置 7组成一个 断路回路，所述指示灯 75不发亮。
请参阅图 6、 图 7 ,当所述内部加热容器 1内产生了微裂纹，高温金属 材料 9少量泄漏至外部加热容器 3时，长度较长的第一高阻值端子 R1接触 泄漏的高温金属材料 9 ,且第一高阻值端子 R1导通内部加热容器 1、 外部 加热容器 3、 电源 6与指示装置 7 ,整个电路连通，此时该电路的总电阻值 为 R1 ,电路内形成的电流较小，仅能触发具有较低的初始电流 II的第一指 示灯 L1亮起，显示高温金属材料 9有轻微泄漏，而具有较高的初始电流 12 的第二指示灯 L2内仅有电流通过，并不发亮。 请参阅图 8、 图 9 ,当所述内部加热容器 1内产生微裂纹较严重，高温 金属材料 9大量泄漏至外部加热容器 3时，长度较长的第一高阻值端子 R1 与长度较短的第二高阻值端子 R2同时接触泄漏的高温金属材料 9旦第一、 第二高阻值端子 Rl、 R2形成并联关系，导通内部加热容器 1、 夕卜部加热容 器 3、 电源 6与指示装置 7,整个电路连通，此时该电路的总电阻值为（ R1 xR2 ) / ( R1+R2 ) ,较上述 R1值降低，电路内形成的电流则增大，触发具 有较低初始电流 II的第一指示灯 L1及较高初始电流 12的第二指示灯 L2 同时亮起，显示所述高温金属材料 9有大量泄漏，并提示技术人员做出相 应处理，防止高温金属材料进一步泄露。
同理，当该加热装置包括更多数量的端子 5与指示灯 75时，不同数量 的端子 5与泄漏的高温金属材料 9接触，使得电路的电阻不同，对应流经 电路的电流也不同，从而触发不同数量的指示灯 75亮起，显示所述内部加 热器 1已经泄漏以及所述高温金属材料 9泄漏的大致高度，能够实现更加 精确的对高温金属材料 9泄漏量的侦测、 判定，提示技术人员做出相应的 处理，防止高温金属材料进一步泄露，维持 OLED生产的正常、 稳定运行。
综上所述，本发明侦测和防止高温金属材料泄漏的加热装置，通过设 置内部加热容器与外部加热容器构成双层结构，并在内部、 外部加热容器 之间设置不同高度的端子、 电源及指示装置，由观察指示装置的指示灯的 亮起情况，即可方便、 及时的侦测到高温金属材料的泄漏，提示技术人员 做出相应处理，防止高温金属材料进一步泄漏，克服因加热容器损坏导致 金属材料损失的问题，从而节约生产成本，保护加热设备，防范生产中断 的相关风险，维持 OLED生产的正常、 稳定运行。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形 都应属于本发明后附的权利要求的保护范围。
