Abstract

The invention relates to a display shell and a manufacturing method thereof, particularly a display shell for entertainment in festival celebration. According to the display shell, compressed air is used as power for driving an air cylinder (1) to lift off and a sound amplification cylinder (21) to explode and jet a flash piece (11); a parachute (19) is utilized to reduce the falling speed; and a broad light (9) is utilized to illuminate the night sky. The method of generating new technical effects under a certain action in the form of an operation mode and a technical process is utilized to represent the technical scheme. The invention has outstanding features and marked progresses. The display shell provided by the invention can implement continuous explosions and colorful fireworks after lift-off, does not generate discharge pollution of smoke, Pm2.5 dust or carbon, is safe in the aspects of production, storage, transportation and application, and can be used repeatedly, thereby becoming an upgraded new-generation safe environment-friendly display shell.
