[0002] A hanging filter is a device used for circulating water in aquariums. It contains filter media that adsorbs and purifies pollutants in the water. Currently, most hanging filters on the market have a single-layer structure. The incoming water must pass through the horizontally arranged filter media sequentially, and there is no guiding structure for the water flow. This can easily lead to water flowing to one side of the filter media, resulting in insufficient filtration and underutilization of the filter media.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a suspended filter with a multi-layer structure and discharge through multiple outlet holes, which can increase the contact area between the water and the filter medium.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] See appendix Figure 1-2 This application provides a suspended filter, which includes a first housing 1, a second housing 2 and a bottom housing 3 arranged sequentially from top to bottom. The first housing 1 is provided with a first water cavity 4, the second housing 2 is provided with a second water cavity 5 corresponding to the first water cavity 4, the bottom housing 3 is provided with an inlet 6 connected to the first water cavity 4, the bottom of the first water cavity 4 is provided with a plurality of first water outlet holes 7 evenly distributed, the bottom of the second water cavity 5 is provided with a plurality of second water outlet holes 8 evenly distributed, the second water cavity 5 is provided with a filter structure 9, the second water cavity 5 is connected to the filter cavity on the bottom housing 3, and the bottom housing 3 is provided with an outlet 10 connected to the filter cavity. By setting up a first shell 1, a second shell 2, and a bottom shell 3 arranged sequentially from top to bottom, a multi-layer water cavity structure is formed. Multiple first water outlet holes 7 at the bottom of the first water cavity 4 and multiple second water outlet holes 8 at the bottom of the second water cavity 5 can evenly disperse the water flow, increasing the contact area and time between the water flow and the filter structure 9 in the second water cavity 5. This structure overcomes the disadvantage of traditional single-layer filters where the water flow tends to be biased to one side, making the filtration more thorough and uniform, and improving the overall filtration efficiency and water purification effect.

[0017] The second housing 2 is provided with a first pipe 11 that connects to the water inlet 6, and the first housing 1 is provided with a second pipe 12 that connects to the first pipe 11. The second pipe 12 connects to the first water chamber 4. By providing the first pipe 11 and the second pipe 12 that connect to each other on the first housing 1 and the second housing 2, a reliable connection between the water inlet 6 and the first water chamber 4 is achieved. Furthermore, the first water chamber 4 is provided with a water spray pipe 13, which connects to the second pipe 12. The water spray pipe 13 has multiple third water outlets distributed on it. The water spray pipe 13 allows the water to enter the first water chamber 4 in a spraying manner, avoiding direct impact of the water flow on a certain point, further improving the uniformity of the water flow distribution, and laying a good foundation for subsequent filtration processes.

[0018] The bottom shell 3 is provided with a water receiving tray 14 and a water collecting cavity 15. The water receiving tray 14 is located below the second water cavity 5 to collect water discharged from the second water outlet 8. The water outlet end of the water receiving tray 14 is connected to the water collecting cavity 15, and the water collecting cavity 15 is connected to the water inlet end of the filter cavity. With this structure, the water collecting cavity 15 concentrates the collected water flow and guides it to the water inlet end of the filter cavity, ensuring that the water flow can enter the final filtration stage smoothly and orderly, thereby improving the filtration effect and ensuring that the water output from the water outlet 10 has been completely filtered.

[0019] The filter chamber is provided with multiple filtration zones 16 arranged sequentially and connected in series. Each filtration zone 16 contains a water filter medium. This structure achieves multi-stage filtration, with each filtration zone 16 capable of being filled with a different water filter medium. This allows for graded and step-by-step purification of the water flow, specifically removing different impurities from the water and significantly improving the filtration effect and the quality of the effluent. Specifically, the water filter medium is one or a combination of filter cotton, activated carbon, and ceramic particles.

[0020] The filter structure 9 is a sponge. The sponge has good physical filtration performance and can effectively trap larger particulate impurities in the water. As a preliminary filtration layer, it reduces the burden on the subsequent fine filtration area and extends the service life of the fine filtration medium.

[0021] The upper end of the bottom shell 3, the upper end of the second shell 2, and the upper end of the first shell 1 are provided with connecting steps 17. The lower end of the second shell 2 and the lower end of the first shell 1 can be connected to the connecting steps 17. The upper end of the first shell 1 is covered with a cover 18. This structure facilitates precise docking and fixing between the upper and lower shells, ensuring convenient assembly and structural sealing.

[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
