More importantly, a filter chamber is provided inside the aforementioned outer barrel body 1, and the filter chamber can be divided into two parts, one part is a sedimentation bin 2, and the other part is a filter chamber 3. As shown in the figure, the volume of the filter chamber 3 is larger than the sedimentation bin 2, and the filter chamber 3 is placed on the upper part of the sedimentation bin 2, and the two are interconnected; and multiple layers of horizontal filter baskets 4 are provided in the filter chamber 3. As shown in the figure, the aforementioned filter baskets are set to 5 layers in this embodiment; at the same time, the sedimentation bin 2 also needs to be connected to the water inlet pipe 5, and the water inlet pipe 5 is provided with a water pump 6. The water pump 6 can be installed in a dedicated cavity at the bottom of the filter chamber 3, but its water outlet The filter bin 3 has a filter element 10 and a filter element 2 therein. The filter bin 3 has a filter element 10 and a filter element 3 has a filter element 12. The filter bin 3 has a filter element 10 and a filter element 3 has a filter element 13. The filter bin 3 has a filter element 10 and a filter element 3 has a filter element 14. The filter bin 3 has a filter element 10 and a filter element 3 has a filter element 15. The filter bin 3 has a filter element 10 and a filter element 3 has a filter element 16. The filter bin 3 has a filter element 10 and a filter element 3 has a filter element 17. The filter bin 3 has a filter element 10 and a filter element 18. The filter bin 3 has a filter element 10 and a filter element 19. The filter bin 3 has a filter element 10 and a filter element 10 has a filter element 10. The filter bin 3 has a filter element 10 and a filter element 19 ...

[0016] In this embodiment, by arranging a sedimentation bin 2 and a filter bin 3 inside the outer barrel body 1, the water entering the outer barrel body 1 through the water inlet pipe 5 first enters the sedimentation bin 2 for sedimentation, and then passes through the multi-layer filter basket 4 in the filter bin 3 from bottom to top as the water volume increases, and finally is discharged into the fish tank through the water outlet 9 to realize water circulation filtration, and backwashing and drainage can be carried out through the sewage outlet 7 on the sedimentation bin 2, without removing the multi-layer filter basket 4 for cleaning, which is not only convenient to clean, but also will not affect the water quality of the fish tank during the cleaning process.

[0017] Still reference Figure 1 and Figure 2As shown, according to another embodiment of the utility model, in order to facilitate the above-mentioned backwashing, a water inlet switch 51 can be installed on the above-mentioned water inlet pipe 5, a water outlet switch 91 can be installed on the water outlet pipe 9, and a water adding switch is provided on the water inlet 10. In this embodiment, each switch can adopt a commonly used valve body switch. Since the structure of such a switch has long been known to those skilled in the art, it will not be described in detail here. Further, in order to achieve primary filtration, a filter cage 52 can also be provided at the water inlet at the end of the water inlet pipe 5 to prevent larger impurities such as the sink from entering the sedimentation bin along the water inlet pipe. At the same time, similar to the structure of similar aquarium filters, the water inlet pipe 5 can also be connected to the oil removal film device 11, and an oil removal film switch 111 is provided between the oil removal film device 11 and the water inlet pipe 5, and the oil removal film switch 111 controls the opening and closing of the oil removal film device 11. As shown in the figure, the water inlet of the oil removal film device is reversely placed on the water surface of the fish tank, so that the oil film floating on the water surface can be sucked into the above-mentioned sedimentation bin 2 through the water inlet pipe, and filtered through the filter bin 3 together with the water. On the other hand, in order to adapt to water surfaces of different heights, the above-mentioned water inlet pipe 5, water outlet pipe 9 and oil removal film device 11 can be set as telescopic pipe structures that are mutually connected, so as to adjust their lengths.

[0018] refer to Figure 1 and Figure 2 As shown, in actual use, the above-mentioned preferred embodiment of the utility model is as follows: the outer barrel body 1 is mounted on the outer edge of the fish tank, the water inlet pipe 5 is extended below the water surface of the fish tank, and the outer barrel body 1 is filled with water through the water inlet 10, and then the water pump 6 is started. Under the action of the water pump 6, the water in the fish tank is continuously pumped into the sedimentation bin 2. At this time, larger particles of impurities in the water will be precipitated in the sedimentation bin 2, while relatively smaller impurities will flow from bottom to top through the filter basket 4 in the filter bin 3 for circulating filtration. The filtered water is returned to the fish tank through the water outlet pipe 9 at the top of the filter bin 3, thereby realizing continuous filtration. In this process, the oil film on the water surface of the fish tank is also sucked into the sedimentation bin 2 along with the oil film remover. During the long-term use of the device, a lot of impurities will remain on the sedimentation bin 2 and the filter basket 4. If they are not cleaned regularly, their filtration efficiency will be affected. In the structure provided by the utility model, backwashing cleaning can be achieved. Specifically, the power supply of the water pump 6 and the water inlet switch 51 are turned off, and the water outlet switch 91 is turned on to immerse the water outlet pipe 9 below the water surface of the fish tank, and then the sewage switch 8 is turned on. Since the filter chamber is full of water at this time, under the principle of the U-tube, the water in the fish tank continuously flows into the filter chamber along the water outlet pipe 9, and washes the filter basket 4 and the sedimentation bin 2 from top to bottom, and finally the dirt is discharged along the sewage outlet 7 under the action of the water flow. During the entire backwashing process, there is no need to disassemble the components in the filter chamber, which is more convenient to use.
