Title: SMOKE SCREEN GENERATOR
Abstract:
The present invention provides a smoke screen generator that forms smoke screens at a high diffusion rate. Both ends of a cylindrical housing 10 are blocked by a first closure 20 and a second closure 30, and a flow channel-changing member 60 is mounted in such a manner as to be distanced from the second closure 30 in the axial direction. During operation, a smoke screen source passes through a smoke screen source discharge port 38, a first discharge channel 45, 46 and a second discharge channel 47, and is eventually discharged from a final discharge port 48 which is formed as an annular opening. The smoke screen source is discharged radially from the final discharge port 48, so that a smoke screen is formed at a high diffusion rate.
