In this embodiment, there are three water inlets 21, two of which are provided on the left support column 2 and one on the right support column 2. The water outlet 22 is provided on the right support column 2. Correspondingly, Figure 3 As shown, the left side of the cylinder body 1 is provided with two water inlet mounting holes 11, and the right side is provided with a water outlet mounting hole 12 and a water inlet mounting hole 11, and the water inlet 21 and the water outlet 22 extend into the cylinder body 1 from the corresponding mounting holes. Figure 4 As shown, a water inlet pipe 33 and a water outlet pipe 34 are arranged in the bottom shell 3. One end of the water inlet pipe 33 is connected to the water inlet 21, and the other end is connected to the back filter box 4. The water in the cylinder body 1 enters the cavity of the support column 2 through the water inlet 21, and then is transported to the back filter box 4 through the water inlet pipe 33 for filtration; one end of the water outlet pipe 34 is connected to the water pump in the back filter box 4, and the other end is connected to the water outlet 22. The filtered water is transported to the cylinder body 1 again through the water outlet pipe 34. The bottom of the support column 2 and the back filter box 4 are both provided with an interface 27, and the interface 27 is located in the bottom shell 3. The two ends of the water inlet pipe 33 in the bottom shell 3 are connected at the interface 27. The bottom of the support column 2 (i.e., the bottom of the cavity for water inlet) is sealed by a bottom film 210, and the bottom film 210 is connected to the support column 2 by ultrasonic welding.

[0057] In this embodiment, Figure 5 , 8As shown, the water inlet 21 is located inside the cylinder body 1, and a thread is provided on the outer wall, and a fixing nut 23 is connected by the thread. Here, the water inlet 21 is fixed to the cylinder body 1 by the fixing nut 23, and then the support column 2 is fixed to the cylinder body 1. In addition, a protective cover 24 is also provided at the end of the fixing nut 23, and the protective cover 24 can prevent small fish and shrimp from being sucked into the water inlet 21, thereby protecting the small fish and shrimp. An oil removal film assembly 28 is installed at the water outlet 22. In this embodiment, the oil removal film assembly 28 is inserted into the inner wall of the water outlet 22, and the outer periphery of the water outlet 22 is also connected by a fixing nut 23 by a thread. Here, the water outlet 22 is fixed to the cylinder body 1 by the fixing nut 23, and then the support column 2 is fixed to the cylinder body 1. In addition, the water inlet 21 and the water outlet 22 are also covered with a sealing ring 25, and a groove is radially opened on the outer wall of the sealing ring 25.

The filter areas are separated by a partition 44, the water inlet pipe 33 is connected to the bottom of the first filter area 41, and the water outlet pipe 34 is connected to the water pump located in the third filter area 43. In this embodiment, a water inlet grille 45 is provided at the top of the partition 44 between the first filter area 41 and the second filter area 42, and a water inlet grille 45 is provided at the bottom of the partition 44 between the second filter area 42 and the third filter area 43. After the water in the cylinder body 1 enters the first filter area 41 from the bottom of the first filter area 41, it enters the second filter area 42 through the water inlet grille 45 at the top between the first and second filter areas 42. After being filtered in the second filter area 42, it enters the third filter area 43 through the water inlet grille 45 at the bottom of the second and third filter areas 43, and then the water is injected into the cylinder body 1 through a water pump. This structure allows the water to be fully filtered by the first filter area 41, the second filter area 42 and the third filter area 43.

[0059] In addition, the back filter box 4 of this embodiment is also provided with a pipeline area 48 outside the third filter area 43 for placing pipelines.

[0060] A drainage channel 46 is provided at the bottom of the first filtering area 41 to facilitate water replacement and sewage discharge in the fish tank.

[0061] In this embodiment, a protruding pressing block 47 is provided on one side of the bottom of the back filter box 4 near the bottom shell 3. The protruding pressing block 47 extends into the bottom shell 3 to fix the back filter box 4. Figure 4 , 10 As shown, the back filter box 4 and the bottom shell 3 can be quickly and accurately aligned by correspondingly setting a pluggable positioning groove 37 and a positioning block 49 on the bottom shell 3 and the back filter box 4, such as Figure 4 As shown, B is another side structural diagram of A, where the positioning groove 37 and the positioning block 49 are aligned and installed.

[0062] like Figure 10-11 As shown, the bottom shell 3 includes an upper cover plate 31 and a lower cover plate 32, and the upper cover plate 31 and the lower cover plate 32 are supported by a support bar 35, and the support bar 35 plays a role of conducting force, and can finally conduct the weight of the cylinder body 1 and the water body to the lower cover plate 32. In addition, in this embodiment, a bottom drainage hole 36 is opened on the lower cover plate 32, and when water enters the bottom shell 3, the water can be discharged through the bottom drainage hole 36 to avoid water accumulation in the bottom shell 3.

[0063] like Fig.12 As shown, the two ends of the lamp 6 are provided with supporting feet 61, and the two supporting feet 61 are respectively clamped on the top of the two supporting columns 2 to facilitate the disassembly of the lamp 6, thereby facilitating the daily maintenance of the cylinder body 1.

[0064] The ambient light panel 5 is hung on the cylinder body 1 via a hook 51 , so that the ambient light panel 5 can be easily disassembled.

[0065] The fish tank also includes a control panel 7 for controlling the lamp 6, the atmosphere light panel 5, etc. In this embodiment, the control panel 7 is arranged on the front end surface of the right support column 2, the control panel 7 is connected to the circuit board inside the support column 2, and the outer cover plate of the support column 2 on this side is provided with a heat dissipation hole 71 for dissipating heat from the circuit board. Fig.13 As shown, the outer cover plate on this side is a detachable structure, which is connected to the support column 2 by buckling and snapping, so as to facilitate the maintenance of the lines and pipelines. Fig.14 As shown, the internal cavity of the support column 2 located on the right side includes a water inlet cavity for water inlet, a cavity for placing a circuit board, and a cavity for placing a lamp line. A lamp line outlet 29 is provided between the cavity for placing the lamp line and the cavity for placing the circuit board. The lamp line is also connected with a detachable connector to facilitate subsequent replacement. In addition, a certain length of the lamp line should be reserved so that when the lamp 6 is removed, the lamp line can be pulled out, and the lamp line can be placed in the upper cavity after maintenance is completed. Fig.15 , 16 The figure shows a schematic diagram of the internal cavity structure of the two support columns 2.

[0066] The water flow direction of the fish tank is as follows: the water in the tank body 1 passes through the three water inlets 21, enters the back filter box 4 through the water inlet pipe 33, passes through the three filter areas of the back filter box 4 in sequence, and then passes through the water outlet pipe 34 through the water pump, and injects the water into the tank body 1 through the water outlet 22. This cycle repeats.

[0067] In the fish tank of the example of the present embodiment, the filtering device is installed on the outside of the fish tank so that there is enough space inside the fish tank; the water inlet 21 and the water outlet 22 are arranged on the side of the tank body 1, which will not affect the overall aesthetics of the fish tank. When viewed from the front end of the fish tank, the atmosphere light panel 5 is mainly visible, which has good transparency and increases the viewing effect of the fish tank; in addition, the atmosphere light panel 5 is detachable, making it more convenient and flexible to use.
