Zusammenfassung:	The utility model discloses an injection nozzle for jet aeration, and the injection nozzle is that a negative-pressure injection device is arranged in front of a plain nozzle. The front face of a jet hole 5 is provided with a conical bore 6 of a divergence angle of 30 DEG, and the diameter of the front face is suddenly enlarged and provided with a stabilization bore 7 whose aperture is tiny. The character that jet is accompanied with air is used by the utility model to form negative-pressure on the position and aerate, the current velocity of the jet can be accelerated to make the jet dispersed and enlarge the accompanied air flow, back pressure is enhanced, underwater penetration is increased, the utilization rate of oxygen can be enhanced, and thus the oxygenation capacity and the power efficiency of the jet aeration can be enhanced.
