Abstract
The present disclosure provides a cold firework spurting apparatus, comprising: a feeding device; a conveying device; a heating mechanism; and a spurting device configured to ignite and spurt the metal powder heated by the heating mechanism, wherein an output end of the feeding device is open to the conveying device and an output end of the conveying device is open to the spurting device. Accordingly, the metal powder inside the conveying device is continuously heated by the heating mechanism attached to the conveying device during the conveying process such that the metal powder is constantly heated during the conveying process so as to form the metal powder ignited at high temperature. The ignited metal powder at high temperature is led and spurted outwards by means of an air flow formed by the spurting device so as to form a spurting effect of cold firework.
