Title:
BUBBLE GENERATION DEVICE AND BUBBLE GENERATOR
Document Type and Number:
Japanese Patent JP2023086210
Kind Code:
A
Abstract:
To provide a bubble generation device which can mix and dissolve a large amount of micro-sized air bubbles and nano-sized air bubbles into a liquid and discharge the mixture, and to provide a bubble generator.SOLUTION: The invention includes: a liquid contraction hole 41 formed at a nozzle body 19; a liquid guide core 47 having first and second spiral surfaces 55, 56; and a liquid closing plate 46. The liquid guide core 47 is formed integral with the liquid closing plate 46. The liquid closing plate 46 has first and second liquid introduction holes 55, 56. The liquid guide core 47 is attached to the liquid contraction hole 41 from the side of an inflow passage 8, and the liquid closing plate 46 is placed in contact with the nozzle body 19 to close the liquid contraction hole 41. First and second liquid passages δ1, δ2 having spiral shapes are formed between the liquid guide core 47 and the liquid contraction hole 41. A liquid flows into the inflow passage 8 and then flows from the inflow passage 8 into the first and second liquid passages δ1, δ2 through first and second liquid introduction holes 51, 52.SELECTED DRAWING: Figure 9
