摘要： Provided is an ultrafine bubble (UFB) generating apparatus and an UFB generating method capable of efficiently generating an UFB-containing liquid with high purity. The ultrafine bubble generating apparatus (1) includes a generating unit (300) that generates ultrafine bubbles (11) in a liquid (W) and a post-processing unit (400) that performs predetermined post-processing on the ultrafine bubble-containing liquid generated by the generating unit (300). The generating unit (300) generates the ultrafine bubbles by causing a heating element (10), which is provided in the liquid (W) on which the pre-processing is performed, to generate heat to generate film boiling on an interface between the liquid and the heating element.

摘要： There is provided a liquid ejecting apparatus and a liquid ejecting head (5) in which mist does not close an ejection port (7) so as to prevent any degradation of the reliability of ejection. In view of this, a ceiling surface (40) is formed between a mist recovering unit (2) and a gas blowing unit in a mist recovering mechanism, thus forming a recess. Inside of the recess are formed a suction port (20) of the mist recovering unit (2) and a gas blowing port (30) of the gas blowing unit.

摘要： A suction hole (7) sucks air existing in a region S together with mist (12) is formed downstream of a liquid ejecting unit (11), as viewed from the liquid ejecting unit, in a movement direction (i.e., a direction E) of a print medium (P) in the case of relative movement between the liquid ejecting unit and the print medium. Moreover, a blowing hole blows air toward the print medium so as to generate a vortex (V) of gas downstream of the suction hole is formed downstream of the suction hole (7) in the movement direction. Here, a relationship expressed by the following expression is satisfied: γ ≥ h / 3 where y represents a maximum vortex core radius (mm) of the vortex in a direction perpendicular to the print medium and h represents a distance (mm) between a blowing hole and the print medium.

摘要： An ultrafine bubble generating apparatus and an ultrafine bubble generating method capable of efficiently generating an ultrafine bubble-containing liquid with high purity are provided. In order to this, a heating element (10) provided in a liquid (W) is caused to generate heat, and film boiling is made on an interface between the liquid (W) and the heating element (10). A film boiling bubble (13) is generated by the film boiling, and ultrafine bubbles (11) are thus generated near the film boiling bubble (13).
