Abstract:
1. A foaming nozzle, which is connected to a gas generating device for generating a high-pressure gas which has a pressure higher than an atmospheric pressure, and foams, while stirring, a liquid located in a spouting direction by spouting the high-pressure gas from a tip, wherein a set of spouting holes including at least two kinds of spouting holes for spouting the high-pressure gas are formed in parallel in said tip, at least one kind of said at least two kinds of spouting holes is formed in a shape different from a shape of another kind of said at least two kinds of spouting holes so as to spout the high-pressure gas at a speed different from a speed of the high-pressure gas spouted from said other kind of said at least two kinds of spouting holes, flows of the high-pressure gas, having different speeds, in parallel spouted from said at least two kinds of spouting holes are adapted to interfere with each other in the liquid, and a hole cross-section of at least one kind of said at least two kinds spouting holes is a precise circular shape and a hole cross-section of another of said at least two kinds of spouting holes is an elongated circular shape having a larger cross-sectional area than the precise circular shape.
