Description

一种烟花电点火头 技术领域 .
本实用新型涉及一种电点火头， 特指一种不含任何火药、 性能稳定的烟花电点火头。
背景技术
目前市场上， 用于花炮电控燃放的电点火头均为含有火药 的结构， 即在导线对一端短接的电阻丝上包裹有少量的火药， 并通过粘接剂和防潮剂将火药与导线固定为一体。 使用时， 电 流被导向短接在导线之间的电阻丝， 电阻丝迅速发热， 进而引 燃包裹在周围的火药， 火药燃烧产生火焰和高温， 进一步将固 定在周围的烟花引线点燃。
为提高电点火头的点燃率， 其使用的火药往往为敏感度极 高的火药， 从而导致电点火头本身较为敏感， 磨擦或冲击都有 可能触发， 在与烟花的预备装配过程中较为危险。 因此尽管国 际上将这种产品的危爆极别定为较低的 UN0454、 1 . 4 S , 然而很 多国家却将这种电点火头产品定为管制产品， 只允许销售给专 业用户。
火药中的氧化剂成分具有较强的氧化能力， 尽管电点火头 中所用的电阻丝为惰性合金丝， 然而随着储存时间增长或储存 环境的恶劣， 电阻丝会被逐渐氧化， 此时电阻丝的发热性能会 急剧下降， 在未达到触发温度时就会从氧化环节熔断， 从而出 现哑火现象。
实用新型内容
本实用新型所要解决的技术问题是提供一种安全系数高、 性能可靠的无火药稳定的烟花电点火头。
为了解决上述技术问题， 本实用新型是采用下述方案实现 的： 一种烟花电点火头， 它有一电路板、 一对导线、 一根电阻 丝、 一个安装夹和顶盖组成， 其特征是： 所述的电路板固定在 所述的安装夹内， 所述的电路板前端设有 U 形点火槽， 所述的 电阻丝与所述的导线焊接在所述的电路板上且所述的电阻丝跨 骑在所述的 u 形点火槽上， 所述的安装夹设有烟花引线槽， 所 述的顶盖设有引线推进定位板并套盖在所述的安装夹上。
所述的电阻丝为电热转换能力 良好的电阻丝 (如钨丝、 镍 铬合金丝、 康铜丝等等） 绕制成细密的螺旋状。
使用时， 烟花引线插入到安装夹的烟花引线槽内， 当压下 顶盖时， 顶盖的推进定位板压迫烟花引线嵌入并固定在安装夹 的引线固定槽中，发热电阻丝为电热转换能力 良好的电阻丝（如 钨丝、 镍铬合金丝、 康铜丝等等） 绕制成细密的螺旋状并焊接 在电路板的点火槽上， 烟花引线嵌入到电路板的点火槽中， 螺 旋电阻丝受到烟花引线压迫弯曲， 良好地包裹住引线的下半部 分， 通电后电阻丝发热， 烧穿引线的棉线层并引燃引线中的火 药， 从而点燃引线。
由于整个不含有火药成分， 避开了传统烟花电点火头的管 制条例， 能合法销售给广大烟花消费者使用； 由于电阻丝周围 没有强氧化性的火药， 该实用新型长时间储存也不会影响电阻 丝的发热性能， 从而保证了该实用新型稳定的点火性能。
综上所述， 本实用新型是一种安全系数高、 性能可靠且结 构简单、 制造方便、 性能稳定的无火药、 稳定的、 可合法销售 给消费者的烟花电点火头。
