The present invention relates to a microbubble nozzle. The purpose of the present invention is to provide a microbubble nozzle which is capable of forming microbubbles smoothly without the need to drastically decrease the cross section of a flow path for introducing fluid therethrough, and is capable of reducing the generation of water hammering phenomena. The microbubble nozzle comprises: a nozzle main body having an inlet at one side, an outlet at the other side, and a fluid flow path between the inlet and the outlet, the fluid flow path having a smaller cross section compared to the inlet and the outlet; an air supply part having a space part formed at the outer side of the flow path, an air supply hole formed at the space part so as to supply outer air, and a plurality of spray holes intercommunicating with the flow path, the plurality of spray holes being spirally penetrated in a circumferential direction; a spiral fluid supply path formed on the inner surface of the inlet of the nozzle main body; and a fluid collision member installed on the inner surface of the outlet of the nozzle main body, the fluid collision member consisting of a core material in a conical shape and a wing piece outside the core material, wherein the wing piece is formed in a direction opposite to the spiral fluid supply path. |
