Problems solved by technology

[0006] The detonating device with the above structure has the following problems: 1. The thermal reactants to be filled in the detonating device need to be processed by mixing, mixing, coiling or bagging, and the filling process is time-consuming. 2. During the filling process of the detonating device, the oxidant and reductant are prone to uneven mixing, resulting in low heat release efficiency; 3. The thermal reaction material needs to be mixed and filled in advance, and the temperature is too high during transportation. It is highly likely to cause combustion or explosion, and has a greater potential safety hazard; 4. Due to the delay of the detonating material or other situations, it is easy to appear the situation of squibs, and it is impossible to judge the cause of the squibs, so it cannot be eliminated by rowing the squibs Potential safety hazard; 5. The existing gas blaster detonation method uses a solid activator to burn to generate high temperature, which directly conducts heat to liquid carbon dioxide, causing the liquid carbon dioxide to gasify and expand, and its heat absorption efficiency of liquid carbon dioxide is low
[0007] In addition, since the lead wire of the conventional detonator contains two exposed terminals, the wiring needs to be connected separately, and the wiring process takes a long time; in addition, the exposed terminals are prone to the risk of electrostatic contact, and there is a risk of electrostatic detonation
