传统的冷焰火设备采用电子点火，极易短路造成火灾或引发爆炸等事故，在本实施例中，加热机构2能够通过将电能转化成热能或电能转化为电磁能，再由电磁能转化为热能的方式对金属粉末进行加热，使金属粉末达到燃点状态，无需点火装置对金属粉末进行点火，避免了因操作不当引发的安全事故，极大程度上提高了冷焰火设备的安全性能。
具体地，加热机构2还包括加热控制装置，加热控制装置包括温度感应器，加热控制器，温度感应器用于感应送料管内的温度，当温度达到第一预设值时温度感应器发送第一信号至加热控制器，加热控制器控制电源停止向电磁感应加热线圈供电；当温度低于第二预设值时，温度感应器发送第二信号至加热控制器，加热控制器控制电源开始向电磁感应加热线圈供电。
需要说明的是，本申请中涉及到的“第一预设值”是指金属粉末达到燃点，并适合继续传送至喷射机构3时送料管内的温度值，该温度值可根据实际试验情况合理调节；“第二预设值”是指加热机构2停止加热后，送料管内温度降低至一个低温点，在该低温点需要继续升温以达到对金属粉末继续加热至其燃点的需求时，该低温点所处的温度。第一预设值和第二预设值均可根据实际燃放要求、燃放效果进行合理调节，并不限于某个特定的理论值。
本申请实施例中，喷射机构3具体设有第一喷射机构31，第二喷射机构32，第三喷射机构33。
本申请实施例中，供料机构包括：向第一喷射机构31送料的第一送料分机构11；向第二喷射机构32送料的第二送料分机构12；向第三喷射机构33送料的第三送料分机构13；
与第一送料分机构11连接的第一下料分机构41，与第二送料分机构12连接的第二下料分机构42，与第三送料分机构13连接的第三下料分机构43；
第一送料分机构11包括：与第一喷射机构连通的第一送料管，第一送料管内安装有用于传送金属粉末的第一传料丝杆；第一下料分机构41包括：与第一送料管连通的第一下料管，第一下料管内设有用于传送金属粉末的第一下料丝杆。更进一步地，第一传料丝杆与第一下料丝杆配合连接；
第二送料分机构12包括：与第二喷射机构连通的第二送料管，第二送料管内安装有用于传送金属粉末的第二传料丝杆；第二下料分机构42包括：与第二送料管连通的第二下料管，第二下料管内设有用于传送金属粉末的第二下料丝杆。更进一步地，第二传料丝杆与第二下料丝杆配合连接；
第三送料分机构13包括：与第三喷射机构连通的第三送料管，第三送料管内安装有用于传送金属粉末的第三传料丝杆；第三下料分机构43包括：与第三送料管连通的第三下料管，第三下料管内设有用于传送金属粉末的第三下料丝杆，第三传料丝杆与第三下料丝杆配合连接。
本申请实施例中，加热机构2包括：第一加热分机构21、第二加热分机构22、第三加热分机构23，第一加热分机构21包括：环绕设置于第一送料管外侧的第一电磁感应加热线圈；第二加热分机构22包括：环绕设置于第二送料管外侧的第二电磁感应加热线圈；第三加热分机构23包括：环绕设置于第三送料管外侧的第三电磁感应加热线圈；加热机构2还包括为第一电磁感应加热线圈、第二电磁感应加热线圈、第三电磁感应加热线圈供电的电源。
具体地，第一电磁感应加热线圈与第一送料管之间、第二电磁感应加热线圈与第二送料管之间、第三电磁感应加热线圈与第三送料管之间均设有用于固定导线以及覆盖加热区域的加热骨架，第一电磁感应加热线圈、第二电磁感应加热线圈、第三电磁感应加热线圈的外侧均围绕设置有保温隔热外壳。
本申请实施例中，喷射机构3包括：第一喷射机构34、第二喷射机构35、第三喷射机构36；第一喷射机构34包括：与第一送料管连通的第一喷射管，安装于第一喷射管上的第一气流源；第二喷射机构35包括：与第二送料管连通的第二喷射管，安装于第二喷射管上的第二气流源；第三喷射机构36包括：与第三送料管连通的第三喷射管，安装于第三喷射管上的第三气流源。
具体地，喷射机构3还包括流量控制器，流量控制器用于控制第一气流源、第二气流源、第三气流源所提供的气流量的大小。
流量控制器的设置能够调节喷射管内的气流量，不同的气流量能够产生不同的喷射高度和喷射效果，克服了现有技术中冷焰火燃放效果和燃放高度不可控，应用灵活性差的缺陷。
具体地，第一喷射管的中心轴线与第二喷射管的中心轴线所成的夹角同第三喷射管的中心轴线与第二喷射管的中心轴线所成的夹角相等。
本申请实施例中，冷焰火设备还包括用于存放金属粉末的第一料箱、第二料箱、第三料箱，第一料箱与第一下料分机构41连通，第二料箱与第二下料分机构42连通，第三料箱与第三下料分机构43连通。
现有技术中的冷焰火设备多为一次性燃放设备，一次使用过后无法再次利用，只能够丢弃，如此不但浪费资源，也加重了对环境的污染，在本实施例提供的冷焰火设备中，增设了用于存放金属粉末的第一料箱、第二料箱、第三料箱，料箱内的金属粉末可随时更换、添加，确保本实施例提供的冷焰火设备的循环性使用以及长久性使用，相较于现有技术而言，节约了成本，也更加环保。
以上对本发明所提供的电动阀及电动阀的制造方法进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
