The invention discloses a plug-in type gas blaster igniter and a
cracking device. The plug-in type gas blaster igniter comprises a shell, a filling cavity, an ignition mechanism and an inflation mechanism, the filling cavity is formed in the shell, the shell is connected with and seals the ignition mechanism and the inflation mechanism, the ignition mechanism comprises an
electric heating wire, a wire, a wire punched hole, a seal substrate and a plug-in slot, the
electric heating wire is connected with the wire, the axial core of the seal substrate is the wire punched hole, the plug-in slot is located in the upper portion of the wire punched hole, a positive pin and a negative pin are installed inside the plug-in slot, a positive wire body and a negative wire body of the wire penetrate through the wire punched hole to be connected with the positive pin and the negative pin respectively, one end of the wire punched hole is an internal thread hole, an internal seal rubber
gasket is installed at the bottom of the internal thread hole which cooperates with a punched hole screw, the axis of the punched hole screw is provided with a punched hole, the wire penetrates through the internal seal rubber
gasket and the punched hole screw, the punched hole screw cooperates with the internal thread hole to compress the internal seal rubber
gasket, and the wire is sealed; the plug-in type gas blaster igniter has the advantages of being low in manufacturing cost, high in reactant mixing uniformity, high in heat release efficiency and good in transport safety.
