The breeding cavity 211 of the landscaping tank 200 is used for breeding aquatic ornamental animals, and the first filtering cavity 212 is used for accommodating a bacteria room gathering basket; the second filter volume 213 is used for growing hydroponic plants.

Because the feeding cavity 211 is communicated with the first filtering cavity 212 through the first diversion part 221, and the feeding cavity 211 is positioned above the first filtering cavity 212, water in the feeding cavity 211 flows to the first filtering cavity 212 under the action of gravity, and in the process that the water in the feeding cavity 211 flows to the first filtering cavity 212, excrement of the aquatic animals fed in the feeding cavity 211 flows to the first filtering cavity 212 together with the water, the first filtering cavity 212 contains the bacteria room gathering basket, and the excrement can be filtered and decomposed by bacteria in the bacteria room gathering basket;

the water in the first filter volume 212 will be pumped by the water pump into the second filter volume 213 above the first filter volume 212, and the water can be filtered and purified by the hydroponic plants cultivated in the second filter volume 213;

the second filtering and containing cavity 213 is communicated with the feeding and containing cavity 211, and in the process that water in the feeding and containing cavity 211 flows to the first filtering and containing cavity 212, the water level of the water can gradually fall, and after the water level in the feeding and containing cavity 211 falls, water in the first containing cavity is pumped into the second filtering and containing cavity 213 due to the water pump, so that the water level of the second filtering and containing cavity 213 rises, and therefore the water in the second filtering and containing cavity 213 can flow to the feeding and containing cavity 211, and a water circulation and purification system can be formed.

In summary, based on the above structure, the landscaping cylinder 200 circulates in the feeding cavity 211, the first filtering cavity 212 and the second filtering cavity 213, and both the first filtering cavity 212 and the second filtering cavity 213 can filter and purify the circulating water; from this, can guarantee through first filtration appearance chamber 212 and second filtration appearance chamber 213 that the suitable aquatic animals of quality of water environment that raises in the appearance chamber 211 ornamental animal survives to through hydrologic cycle's mode, can reduce this make a scenery jar 200 water consumption, and can reduce the frequency of changing water, thereby can reduce this make a scenery jar 200 the maintenance degree of difficulty and the maintenance cost.

Further, please refer to fig. 1-7, fig. 4-7 show the structure of the water circulation structure in the embodiment of the present invention; in this embodiment, since the second filtering cavity 213 is communicated with the feeding cavity 211, and the first diversion part 221 of the water circulation structure 220 is used for communicating the feeding cavity 211 with the first filtering cavity 212, and the second diversion part 222 communicates the first filtering cavity 212 with the second filtering cavity 213, a path of water circulation can be formed, and when the first diversion part 221 is provided, in order to enable water in the feeding cavity 211 to flow into the first filtering cavity 212, and it is necessary to prevent the ornamental animal fed in the feeding cavity 211 from moving into the first filtering cavity 212 together with the water flow, the first diversion part 221 needs to have a certain filtering function, and functions to enable water and excrement of the animal to flow into the first filtering cavity 212, and prevent the ornamental animal from moving into the first filtering cavity 212.

Thus, the first guide part 221 includes a spoiler 224 and a plurality of partition plates 223 disposed in the feeding cavity 211, the partition plates 223 are connected to each other to form a guide cavity 225 communicating with the first filtering cavity 212, and the spoiler 224 is located in the guide cavity 225; a plurality of guide holes 226 are formed in at least one of the partitions 223, and the guide holes 226 communicate the guide chamber 225 with the feeding cavity 211. That is, the plurality of baffle holes 226 can enable water and animal excrement to flow into the baffle cavity 225, and the spoiler 224 located in the baffle cavity 225 can play a role of turbulence so as to prevent the excrement from depositing in the baffle cavity 225 and entering the water in the baffle cavity 225, and then the water flows into the first filter container 212, and the ornamental animal can be prevented from moving into the first filter container 212. It should be noted that, in this embodiment, in order to make the water in the feeding cavity 211 smoothly flow into the first filtering cavity 212, a plurality of baffle plates 223 are provided with a plurality of flow guiding holes 226, and the plurality of flow guiding holes 226 are all strip-shaped holes.
