The technical means and structure of the present invention for achieving the purpose, together with the embodiment shown in Figures 2 to 5, will be described in detail as follows: As shown in Fig. 2, the aerator in the embodiment The utility model comprises a submersible pump 30 and a floating body 40; wherein: the submersible pump 30 (please refer to the figures 3, 4 and 5 at the same time), an air passage 33 is formed between the motor 31 and the outer casing 32, An air inlet 321 is disposed at an upper end of the outer casing 32. The air inlet 321 is connected to the air passage 33. The bottom of the submersible pump 30 is provided with a base 34. The base 34 defines a gas-liquid mixing chamber 35. The upper end surface of the base 34 is provided. There are a plurality of air suction holes 341 extending through the gas-liquid mixing chamber 35. The air suction holes 341 communicate with the air passage 33 between the motor 31 and the outer casing cover 32. The bottom surface of the base 34 is provided with a plurality of water outlets 342. The bottom of the base 34 is provided with a bottom cover 36. The bottom cover 36 is provided with a water suction port 361. The gas-liquid mixing chamber 35 is provided with an impeller 37. The upper end surface of the impeller 37 is provided with a plurality of suction blades 371. The bottom surface is provided with a plurality of water absorbing blades 372, which can be driven by the motor 31 to rotate at a high speed to generate suction. The air is sucked into the gas-liquid mixing chamber 35 by the air suction hole 341 at the upper end surface of the base 34, and the water is sucked into the air-liquid mixing chamber 35 by the water suction port 361 at the bottom of the bottom cover 36, and is sucked into the air of the gas-liquid mixing chamber 35. The water and the water will be agitated and stirred by the impeller 37 at a high speed, so that the air is broken to form fine bubbles dissolved in the water, and then discharged by the drain port 342.

Floating body 40 (please refer to Fig. 5 at the same time), can carry the submersible pump 30, so that the submersible pump 30 can be floated upright on the water surface, so that the air inlet of the top of the submersible pump 30 The 321 is exposed upward to the surface of the water, and the suction port 361 and the drain port 342 at the bottom of the submersible pump 30 are allowed to extend downward into the pool water.
