Patent ID: 7494072

Claim:
A fluid spraying device comprising: a first supply flow path which guides a pressurized liquid; a second supply flow path which guides a pressurized gas; a gas-liquid mixing part which joins said first supply flow path and said second supply flow path and which mixes said liquid and said gas; an ejection flow path which guides a fluid from said gas-liquid mixing part to a branching/joining part; said branching/joining part being provided at an intermediate part of said ejection flow path which, after branching said ejection flow path into a plurality of branch flow paths, rejoins said branch flow paths together; and a flexible spray tube which constitutes a downstream end of said ejection flow path, and a cone-shaped guide which is disposed outside of said spray tube in the diametral direction so that a large diameter side is positioned at a downstream end side, wherein said spray tube comprises a tube main body made of a flexible material, and a plurality of weighting parts which fit said tube main body from the outside and which are fixed to said tube main body at a prescribed spacing along an axial direction of said tube main body.
