Zusammenfassung:	The invention discloses a gunpowder-free environmentally friendly firework machine comprising a motor driving device, a holding device, a cam conveying heating device and an air supply device. The motor driving device is fixed to a bottom support plate. The holding device is used for holding combustible metal powder. The cam conveying heating device is arranged below the holding device, is connected with the motor driving device and is used for heating and conveying the combustible metal powder to the air supply device. The air supply device is used for spraying the burning metal powder. The motor driving device continuously drives the cam conveying heating device, the combustible metal powder is pushed to move to the air supply device, meanwhile in the conveying process, the metal powderis heated continuously, thereby being lit by high temperature, then the air supply device conveys out airflow to spray the lit metal powder out, and thus a cold firework spraying effect is formed.
