<P>PROBLEM TO BE SOLVED: To provide a liquid discharge apparatus which can easily cause activation action by fine bubbles by generating the fine bubbles efficiently and highly densely. <P>SOLUTION: This liquid discharge apparatus 10 comprises a liquid flow storage part 11B with a ring-like cross section formed in the rear part to which a liquid flow is introduced from a liquid introduction port 11c and an outer aperture 13a communicated with the outside, a gas flow introduction channel 13A penetrating the inside of the liquid flow storage part from the rear side to the front side and having an inner aperture 13b facing forward in the front part of the liquid flow storage part, an eddy current formation channel 13A communicated with the liquid flow storage part, extended forward to the surrounding of the gas flow introduction channel while the diameter is reduced more than that of the liquid flow storage part and having a ring-like cross-section up to the inner aperture of the gas flow introduction part and a circular cross-section form the portion facing to the inner aperture, and a liquid discharge port 16a formed in the most front part and communicated with the eddy current formation channel. <P>COPYRIGHT: (C)2008,JPO&INPIT |
