PURPOSE:To obtain smaller particles of liquid at a blocking member, by raising the temperature of a liquid ejected from a small hole of a nozzle toward the blocking member by a heating means. CONSTITUTION:A blocking member 3 is disposed on the downstream side of a nozzle 1 having a small hole 2 in the manner that it is located at a predetermined distance from the nozzle 1, while a liquid pressurizing pump 4 and a liquid tank 5 connected by a pipe are disposed on the upstream side of the nozzle 1. Liquid ejected from the nozzle 1 by the pump 4 is formed into either of three flow patterns, smooth flow, vibration flow and divided flow, according to the shape of the small hole 2, speed of the liquid flow, etc. The jet flow of the liquid impinges onto a blocking member 3, produces various vibration waves near the impinging point, and produces finely divided particles of liquid from the top of the vibration waves. Thus, since smaller particles of liquid can be obtained by use of the blocking member 3 and they are heated on the downstream side of the pressuring pump, it is prevented that the pressurizing pump is heated to a high temperature. |
