In this application embodiment, after control boost rectifier circuit 2 and external power supply switch on through time switch 1, lift rectifier circuit D can carry out the rectification of stepping up earlier to the voltage of external power supply input to make the direct current after the rectification satisfy the charging condition to energy storage capacitor C1. Because switch discharge tube K has certain voltage and switches on the threshold value, promptly before storage capacitor C1's charging voltage does not reach this voltage and switches on the threshold value, storage capacitor C1 is in and lasts the charged state to can guarantee that the electric energy of storage capacitor C1 in satisfies the demand of high-energy ignition, in order to guarantee that switch discharge tube K is punctured the back, the electric energy that storage capacitor C1 released guarantees the success rate that the ignition head DH was igniteed. In addition, through time switch 1 can control boost rectifier circuit 2 and external power supply intermittent type formula conduction, thereby can guarantee boost rectifier circuit 2 intermittent type formula work, it is also that boost rectifier circuit 2 carries out intermittent type formula boost rectification to external power supply input's voltage, so not only can guarantee boost rectifier circuit 2 to the charging effect of energy storage capacitor C1, can also prolong boost rectifier circuit D's radiating time, guarantee boost rectifier circuit 2's radiating effect, thereby avoided boost rectifier circuit 2 to burn out because of the phenomenon that the internal temperature rose, boost rectifier circuit 2's life has been improved, thereby the life of this high energy point firearm has been improved.

In this way, the boost rectifier circuit 2 can perform boost rectification processing on the ac voltage input by the external three-phase ac power supply.
Wherein, the preset duration can be determined according to the working voltage of the boost rectifying circuit 2 and the ignition requirement of the ignition head DH, so as to avoid that the preset duration is longer, the working time of the boost rectifying circuit 2 is longer, thereby causing the higher condition of the self temperature, and simultaneously avoid the failure rate of the ignition head DH when the preset duration is shorter. For example, the preset time period may be 15 seconds, 20 seconds, 30 seconds, or the like.
In the practical use process, supposing that external power supply is 220V alternating current power supply, the preset duration is 20 seconds, two output ends of time control switch 1 are connected with live wire and zero line of external power supply respectively this moment, then provide alternating voltage for boost rectifier circuit 2 clearance formula in 20 seconds through time control switch 1, carry out boost rectification processing to the alternating voltage of intermittent type formula input through boost rectifier circuit 2 in order to charge for energy storage capacitor C1, and then when energy storage capacitor C1's charging voltage is greater than the voltage conduction threshold value of switch discharge tube K, the electric energy based on energy storage capacitor C1 release is igniteed through ignition head DH.

Optionally, the control switch AT is a normally open switch, and AT this time, the user continuously presses the control switch AT within a preset time period, so that the driving coil SJ is controlled to be connected with the external power supply within the preset time period.
Because normally open switch needs the user to continuously press to for self-locking switch, can avoid the user to forget to break off the connection between drive coil SJ and the external power supply because of self-reason.
