BUBBLE LIQUID GENERATING NOZZLE

WIPO Patent Application WO/2023/210028

A1

The present invention provides a bubble liquid generating nozzle that is capable of producing (generating) and jetting bubble liquid in which a large amount of microbubbles and a large amount of ultrafine bubbles are mixed and dissolved.　The present invention comprises: a nozzle body 1 that has a cylinder body 8 and a closing plate 9 that closes a cylinder end 8A that is one end of the cylinder body 8, the nozzle body 1 forming, in the cylinder body 8, an inflow space δ into which a liquid flows; a liquid jetting hole 2 that passes through the closing plate 9 and communicates with the inflow space δ; and a liquid guide 23 that is disposed from the inflow space δ into the liquid jetting hole 2. The liquid jetting hole 2 is formed as a conical hole. The liquid guide 23 is formed in a conical shape. A conical side surface 23C of the liquid guide 23 is formed on an irregular surface in which protrusion sections 31 and recessed sections 32 are arranged. The liquid guide 23 forms a liquid flow path ε between the irregular surface of the conical side surface 23C and a conical inner circumferential surface 2a of the liquid jetting hole 2, and is mounted from a conical upper surface 23A into the liquid jetting hole 2.
