Development Status and Trend of Smoke Machine

Development history and classification of foggers at home and abroad were introduced.Concepts of fog，atomization and secondary atomization were analyzed，and influencing factors of atomizing droplets were also analyzed.Through analysis of combination of smog machine and other technologies，three core challenges faced by smoke machine were combed，including intelligent informatization，environmental protection and working environment，and countermeasures were put forward，so as to provide reference for further development of smoke machine.
