As explained above, according to the aerator of the present invention,
A bracket is provided on the lower surface side of the mount so as to fit over the vertical axis of the upper part of the water spraying wing body, a flange face plate is attached to the lower end side of this bracket, and the water lifting wing body is provided in the lower end opening. At the upper end of the water pump, a flange face plate is installed in a row toward the outer circumferential direction.
Since this flange face plate is connected to the flange face plate of the bracket via a spacer, water can be forcibly pumped up from the bottom opening of the water pump tube set at an arbitrary depth and aerated. By simply installing this as a wing body in the middle or deep layer, water can be forcibly lifted, and the vertical shaft that commonly drives the water spraying wing body and the lifting wing body can be made short and small in diameter. Overall, through simple improvements, it has been possible to provide an aerator that can aerate from deep water to near the water surface, with a simple structure and low cost.
