The invention relates to the technical field of gas generators, in particular to an electric ignition tube and a gas generator. The electric ignition tube comprises a gunpowder cavity group, a tube body and an electrode tube group; a plurality of gunpowder cavities are arranged in the gunpowder cavity group, and each gunpowder cavity contains ignition powder and ignition powder; the tube body is sleeved outside the electrode tube group and the gunpowder cavity group, and the electrode tube group is propped against the ignition powder; wherein the electrode tube group is used for igniting the ignition charge in the plurality of gunpowder chambers at the same time or in stages. The electric ignition tube is applied to the gas generator, is simple in structure and convenient to mount, and can realize simultaneous or hierarchical control during ignition, so that the hierarchical gas production function of the gas generator is realized; and the structural size is small, and the occupied internal space of the gas generator can be reduced, so that the space utilization rate of the gas generator can be improved, and the manufacturing and using cost of the gas generator is reduced.
本发明涉及气体发生器技术领域,具体而言,涉及一种电点火管和气体发生器。电点火管包括火药腔组、管体及电极管组;火药腔组内置有多个火药腔室,且每个火药腔室均容置有引火药以及点火药;管体套设于电极管组及火药腔组外,且电极管组与引火药抵持;其中,电极管组用于同时或分级引燃多个火药腔室内的引火药。该电点火管应用于气体发生器中,其结构简单,安装方便,并能够实现点火的同时或分级控制,进而实现气体发生器的分级产气功能;而且其结构体积小,能够减少占用的气体发生器的内部空间,从而能够提高气体发生器空间利用率,降低气体发生器的制作和使用成本。
