[0005] One end of the first connecting pipe is connected to the ball valve, and the other end is connected to the second connecting pipe; the other end of the second connecting pipe is connected to the vent plate; one end of the third connecting pipe is connected to the vent plate, and the other end is connected to the pressing plate;

[0006] The vent plate is provided with a plurality of evenly arranged vent holes;

[0007] An air cavity is arranged inside the pressing plate.

[0008] Furthermore, a tapered tube is provided between the first connecting tube and the second connecting tube, the connecting end of the tapered tube with the first connecting tube is the outer end, and the connecting end with the second connecting tube is the inner end, and the diameter of the tapered tube gradually increases from the outside to the inside.

[0009] Furthermore, a filter plate is provided in the air cavity, and a plurality of filter holes are provided on the filter plate.

[0010] Furthermore, the first connecting pipe, the second connecting pipe and the third connecting pipe may be straight pipes or curved pipes.

[0011] A propeller has a hole on its groove wall, and the hole is connected to the aeration and oxygenation device.

[0013] The present invention has the beneficial effects:

[0014] The present invention provides an aeration and oxygenation device and a propeller. A hole is opened on a groove wall of the propeller and the aeration and oxygenation device is installed at the hole to increase the air intake of the propeller, thereby improving the oxygenation effect of the propeller on the water area. The aeration and oxygenation device adopts a multi-section pipeline design and can adjust the pipeline structure according to the structure of the hull. The ventilation hole plate improves the uniformity of the air intake, and the filtering hole plate prevents the water plants in the propeller from entering the pipeline of the device.
