DETAILED DESCRIPTION

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Example 1:

[0030] like Figures 1-5 As shown, this embodiment provides an aquarium filter, including an upper cover 1 and a lower shell 2 that are detachably connected. Both the upper cover 1 and the lower shell 2 are cup-shaped structures, separated by the bottom surface of the upper cover 1. Both the upper cover 1 and the lower shell 2 have a central cavity, wherein the central cavity 3 of the upper cover extends vertically and communicates with the central cavity 4 of the lower shell. A negative pressure generating device is installed in the central cavity, which drives the flow of water. A permeable grid 5 is provided on the bottom surface of the upper cover 1, and a through hole 6 is provided on the wall of the central cavity 4 of the lower shell. Physical filter media 7 is placed in the upper cover 1, and biological filter media 8 can be placed in the lower shell 2. Under the action of the negative pressure generating device, the water flows through the physical filter media 7 and the biological filter media 8 sequentially before being discharged, thus achieving filtration.

[0031] Specifically, the negative pressure generating device includes a water outlet 9 connected to the central cavity 3 of the upper cover. Filtered water flows out from the outlet on the side of the water outlet 9. The water outlet 9 is equipped with an air pipe interface 10. The upper end of the air pipe interface 10 is connected to an air pump via an air pipe, and the lower end is connected to a connecting pipe 11 located in the central cavity. The end of the connecting pipe 11 is connected to an air stone 12. Gas is pumped into the filter by the air pump. The gas enters the central cavity sequentially through the air pipe, air pipe interface 10, connecting pipe 11, and air stone 12. The air stone 12 generates bubbles, which rise to create negative pressure, driving the water flow upward from the bottom of the central cavity 4 of the lower shell. This ultimately drives the water flow from the physical filter media 7 at the upper cover 1 through the biological filter media 8, and finally discharges it into the fish tank, achieving water purification. Furthermore, in this embodiment, the water outlet 9 and the central cavity 3 of the upper cover are connected by an inner pipe 13, which is inserted into the central cavity 3 of the upper cover. The inner tube 13 can move up and down within the central cavity 3 of the upper cover, thereby adjusting the height of the water outlet 9.

[0032] The upper cover 1 and the lower housing 2 are connected by a fastening mechanism. In this embodiment, the lower end of the upper cover 1 is inserted into the lower housing 2, and a sealing ring 14 is provided in the outer wall of the upper cover 1 to fix and seal the fastening point.

[0033] The inner bottom surface of the lower shell 2 is provided with a rib 15, which can support the biochemical filter material 8, thereby forming a good water flow channel.

[0034] The water flow direction is: the water in the fish tank enters the filter under the action of the negative pressure generating device, and then passes through the physical filter material 7, the water-permeable grid 5, the biochemical filter material 8, the through hole 6, the lower shell center cavity 4, the upper cover center cavity 3, the inner tube 13, and the water outlet head 9, and then enters the fish tank again from the water outlet of the water outlet head 9, thereby realizing filtration.

[0035] The aquarium filter of the embodiment example can directly place the material filter in the cup-shaped upper cover 1, which facilitates cleaning and replacement of the physical filter material 7, and the upper cover 1 is easy to disassemble, which facilitates cleaning of the biochemical filter material 8. In addition, the upper cover 1 and the center cavity of the lower shell 2 are assembled to form a water flow channel, so that the filter structure is more compact, the volume of the filter is saved, and the filter installation and maintenance are facilitated.

[0036] Embodiment two:

[0037] As shown in Figure 6 The difference between the embodiment and embodiment one is the structure of the buckle. In the embodiment, the upper cover 1 and the lower shell 2 are connected through the buckle 16 and the sliding groove 17 structure. As shown in Figure 7 The upper cover 1 is buckled on the top outer side of the lower shell 2, the bottom end inner side of the upper cover 1 is provided with the buckle 16, the top end outer side of the lower shell 2 is provided with the L-shaped sliding groove 17, the buckle 16 is buckled into the sliding groove 17, and the upper cover 1 and the lower shell 2 are relatively rotated, the buckle 16 is buckled into the sliding groove 17, thereby buckling and connecting the upper cover 1 and the lower shell 2.

[0038] Those skilled in the art should understand that the utility model range involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the utility model concept. For example, the above features are replaced with the technical features disclosed in the present application (but not limited to) having similar functions to form technical solutions.
