如上所述的多方式启动干粉灭火球，所述第一引线为热引发线。
如上所述的多方式启动干粉灭火球，所述第二引线位于引发剂内的一端上还连接有电火柴。
如上所述的多方式启动干粉灭火球，所述球体外周面上在过其球心的平面上还设有环形槽，所述第一引线的引出端缠设在所述环形槽内。
如上所述的多方式启动干粉灭火球，所述球体外周面上在过其球心的水平面上还设有环形槽以及在过其球心的竖直平面上还设有竖向环形槽，所述第一引线设有2条，分别缠设在所述环形槽以及竖向环形槽内。
如上所述的多方式启动干粉灭火球，所述球体包括具有内腔的球壳体，所述球壳体上开设有缺口，所述缺口上还设有用于封堵缺口的塞子。
与现有技术相比，本发明有如下优点：
1、本发明提供了多方式启动干粉灭火球，其启动方式可由第一引线启动(其由温度到达燃点后燃烧从而启动内部的驱动装置)，也可由第二引线启动，第二引线为电导线，通过第二引线与外部电路、传感器等连接，实现灭火球的自动启动，而且多个灭火球可实现 同时启动，以实现第一时间灭火，减少火灾带来的损失。
2、本发明多方式启动干粉灭火球其结构简单，通过外接烟感、温感等检测器件，实现达到条件后自动启动，能够第一时间作用在火灾现场，而且能够通过第二引线实现远程操控，由人工远程启动。
【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明多方式启动干粉灭火球的结构示意图；
图2为多方式启动干粉灭火球的半剖视图。
【具体实施方式】
为了使本发明所解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明是通过以下技术方案实现的：
如图]、图2所示，多方式启动干粉灭火球，包括球体1，所述球体1内设有灭火介质2，所述球体1内还设有启动后使所述球体1内部膨胀至其爆破的驱动装置3，所述驱动装置3上设有延伸至球体1外在受热后可使所述驱动装置3启动的第一引线4，所述驱动装置3上还设有延伸至球体1外在通电后可使所述驱动装置3启动的第二引线5。本发明提供了多方式启动干粉灭火球，其启动方式可由第一引线启动(其由温度到达燃点后燃烧从而启动内部的驱动装置)，也可由第二引线启动，第二引线为电导线，通过第二引线与外部电路、传感器等连接，实现灭火球的自动启动，而且多个灭火球可实现同时启动，以实现第一时间灭火，减少火灾带来的损失。
具体地，通过外接烟感、温感等检测器件，实现达到条件后自动启动，能够第一时间作用在火灾现场，还可通过外接按钮启动。而且多个灭火球能够通过第二引线实现相互并联，从而实现由人工远程操控。
另外，所述灭火介质2为干粉灭火剂，比如采用平均粒径小于20微米的碳酸氢钠、碳酸氢钾、磷酸一氢铵、磷酸二氢铵、硫酸铵或聚磷酸铵等，要求流动性符合GA578-2005标准。
进一步地，所述驱动装置3包括设于所述球体1内的引发剂31，所述第一引线4和第二引线5的一端位于引发剂31内。通过引发剂31作用，使内部膨胀，从而使球体爆开，使其内部的灭火介质2能够喷发出来从而实现灭火。具体地，引发剂可采用高氯酸钾和镁粉，其受热或遇明火后会产生大量高压气体。
具体地，本方案中，所述第一引线4为热引发线。热敏线由三根不同的药芯引线外面包覆一层塑料构成，当环境温度达到热敏线启动温度或热敏线遇明火引燃，热敏线迅速燃烧。使得本申请启动迅速，可靠。
另外，本方案中，所述第二引线5位于引发剂31内的一端上还连接有电火柴51。通过第二引线(即电导线)通电后可引发电火柴发热或引燃，从而起到启动的作用。利用简单的结构增加了灭火球的启动方式，从而使得灭火球启动实现手动和自动化，能够使其第一时间作用于火灾现场，有效减低火灾带宋的损失。
又进一步地，本方案实施例一，所述球体1外周面上在过其球心的平面上还设有环形槽101，所述第一引线4的引出端缠设在所述环形槽101内。当火灾烧到外侧的第一引线4从而使其引燃时，能够启动内部的启动装置。而且设置在其过其球心的水平面上，能够最大程度增加其接触面积。本方案中该设置利于当手动作用时，即传统用法将灭火球扔到火灾处使用。
另外，本方案实施例二，所述球体1外周面上在过其球心的水平面上还设有环形槽101以及在过其球心的竖直平面上还设有竖向环形槽102，所述第一引线4设有2条，分别缠设在所述环形槽101以及竖向环形槽102内。通过十字交叉型设置，能够进一步增加第一引线的接触面积，从而实现更搞笑的启动。
再进一步地，球体的具体结构为，所述球体1包括具有内腔的球壳体，所述球壳体上开设有缺口，所述缺口上还设有用于封堵缺口的塞子9。简单的结构，便于灭火球的制造和灭火介质的安装。
本发明提供了多方式启动干粉灭火球，其启动方式可由第一引线启动(其由温度到达燃点后燃烧从而启动内部的驱动装置)，也可由第二引线启动，第二引线为电导线，通过第二引线与外部电路、传感器等连接，实现灭火球的自动启动，而且多个灭火球可实现同时启动，以实现第一时间灭火，减少火灾带来的损失。
如上所述是结合具体内容提供的一种或多种实施方式，并不认定本发明的具体实施只局限于这些说明。凡与本发明的方法、结构等近似、雷同，或是对于本发明构思前提下做出若干技术推演，或替换都应当视为本发明的保护范围。
