Patent number: 11980854Abstract: Provided is a liquid supply apparatus which is capable of directly taking in a liquid from a flow channel and appropriately mixing a gas into the liquid when generating-nanobubbles in the liquid using an ultrafine bubble generating apparatus. The liquid supply apparatus comprises a flow channel for a liquid supplied from a liquid supply source and an ultrafine bubble generating apparatus for generating nanobubbles in the liquid. The ultrafine bubble generating apparatus is provided with: a liquid ejector for ejecting the liquid taken in from the flow channel; a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector; and a nanobubble-generating nozzle for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough.Type: GrantFiled: May 29, 2019Date of Patent: May 14, 2024Assignee: AQUASOLUTION CORPORATIONInventor: Yukihiro Tsuchiya

Patent number: 10874996Abstract: To provide a nanobubble generating nozzle that is compact and capable of generating nanobubbles with high efficiency. The problem is solved by a nanobubble generating nozzle and a nanobubble generator including this nanobubble generating nozzle. The nanobubble generating nozzle includes an introduction part for introducing a mixed fluid of a liquid and a gas into an interior thereof, a jetting part for feeding out the mixed fluid containing nanobubbles of the gas, and a nanobubble generating structure part for generating nanobubbles of the gas, between the introduction part and the jetting part. The nanobubble generating structure part includes a plurality of flow paths having different cross-sectional areas through which the mixed fluid of the liquid and the gas is passed, in an axial direction of the nanobubble generating nozzle.Type: GrantFiled: January 3, 2019Date of Patent: December 29, 2020Assignee: AQUA SOLUTION CO., LTD.Inventors: Yukihiro Tsuchiya, Tomohiro Ota, Takahumi Goto
