Abstract
The utility model discloses an electronic detonator module, comprising a detonator leg wire, an electronic detonator control chip, an ignition head, an energy storage device and a discharge device. The discharge device comprises a resistance connected in parallel at the two ends of a detonating capacitance in the energy storage device. The resistance slowly releases energy stored in the detonating capacitance, thereby ensuring that the electronic detonator is reliably in the safe state after power supply on the outside of the electronic detonator is stopped for enough time. Meanwhile, the resistance-value of the resistance is in megohm magnitude, to ensure that the discharge time of a discharge loop composed of the resistance and the detonating capacitance is far larger than the working time of the electronic detonator control chip working normally, thereby ensuring that the electronic detonator still reliably detonates after the external power supply is stopped for a long time.
