[0017] By adopting the above technical solution, the beneficial effects of the present invention are:

[0018] 1. This scheme realizes the planting of plants by setting up a suspended planting floating bed, and realizes the presentation of water mist landscape by using a water mist device. In order to achieve a large amount of water mist, close to the water surface, and strong stability, the specific structure of the water mist device has been adjusted, and it is realized by using a floating ring, a counterweight ring, a metal plate, a support frame, piezoelectric ceramics, and a water flow stirring device. The metal plate can be a conventional metal plate such as a copper plate and a steel plate. The water flow stirring device is used to stir the water to the lower end of the metal plate, so that the piezoelectric ceramics can be used to achieve vibration, so that the water landscape holes are atomized, which does not push the water mist much, the mist output is large, and the stability is good.

The filter structure can effectively ensure the cleanliness of the water source. The filter structure can use a conventional filter cartridge, etc.

[0021] 4. The setting of the aeration device can effectively achieve a better aeration effect. Through the setting of the main tube, the contraction tube and the expansion tube, an effective jet can be formed when the airflow flows out. Among them, the reversing impeller can change the direction of the blown airflow and flow toward the expansion tube, and through the setting of the air guide pipe and the wind flow guide body, the airflow can form two flow directions. The airflow through the avoidance hole forms the main airflow, and the airflow through the air guide pipe forms a disturbed airflow, thereby achieving a better aeration effect. In order to reduce the direct and large-scale entry of the airflow into the air guide inlet, a baffle ring is set, and the air guide tube is in the shape of a trumpet to achieve a primary airflow expansion, and then a secondary airflow expansion is formed through the contraction tube and the expansion tube, so that a better airflow disturbance and airflow promotion effect can be achieved.

[0022] 5. The setting of the spiral guide protrusion can make the airflow form a spiral shape, effectively increase the airflow disturbance effect, and also effectively increase the propulsion effect of the airflow.

[0023] 6. The cross-section of the air duct gradually decreases from the air inlet to the air outlet. The middle part of the air duct bulges in an arc shape away from the aeration cylinder. The angle between the air outlet and the vertical plane is 40°-70°. These technical features are set to enhance the disturbance effect.

[0024] 7. The ratio of the inner diameter of the avoidance hole to the inner diameter of the main tube is 1:4-2:4. The setting of this ratio can achieve better airflow distribution, thereby achieving an effective balance between propulsion and aeration. BRIEF DESCRIPTION OF THE DRAWINGS
