Abstract

The utility model discloses a distant remote-control firecracker setting off device, which is suitable for distantly setting off fireworks and firecrackers and other dangerous objects to be burnt by remote control and keeps off personal injury which is often occurred during the process of setting off fireworks and firecracker. The distant remote-control firecrackers setting off device is characterized in that a remote control sends out a remote control signal to a signal receiving device which irradiates at long distance and is mounted on the firecracker setting off device, then the remote control signal is changed into a control electrical signal by a conversion control circuit through reception, conversion, amplification and detection, and a trigger circuit is conducted to make a load work and set off the firecracker. The load of the firecracker setting off device consists of three parts (shown in the figure) including a fuel steam supplier A, an electromagnet B and a fuel steam electronic lighter C. The electromagnet makes a valve of the fuel steam supplier open, the fuel steam is discharged from a fuel steam supplying port (32) of a fuel steam passage on the fuel steam supplier, high-voltage discharge needles (T1 and T2) of the fuel steam electronic lighter generates electric spark at the fuel steam supplying port of the fuel steam passage, and then the fuel steam fires to set off the firecracker.
