The invention discloses a
gunpowder-free cold firework eruption device, which belongs to the technical field of cold firework performance, and comprises a rack, an ignition
assembly, a feeding
assembly, an injection structure and an air supply device, the input end of the ignition
assembly is connected with a discharging port of the feeding assembly, the ignition assembly is used for electromagnetically heating
metal powder and inputting the
metal powder into the spraying structure, the spraying structure is arranged at the output end of the air supply device, and the air supply device introduces
airflow into the spraying structure to spray the ignited
metal powder. By arranging the ignition assembly and the ventilation structure,
metal powder can be ignited in all directions in an
electromagnetic mode, meanwhile, air is blown into the ignition assembly through air pressure of the air supply device, the
metal powder can be preliminarily ignited in the ignition assembly, and the situation that the
metal powder cannot be fully ignited when entering the injection structure to be erupted is avoided; therefore, the problem that the cold
fireworks are poor in ornamental value due to the fact that the cold
fireworks eruption device is prone to insufficient
combustion during ignition is effectively solved.
