Description

Technical Field

[0001] The utility model relates to the technical field of aquarium filtering devices, in particular to a pneumatic aquarium filtering device. Background Art

[0002] Most pneumatic aquarium filters currently on the market use sponge as the filter medium. An aerator pump pumps air into the filter's inner chamber, draining the water. Water then flows in through the sponge, replenishing the inner chamber. This cycle repeats, creating a water flow that allows the sponge to filter particulate matter from the water. However, this filtration method doesn't foster nitrifying bacteria. Some filters incorporate both physical and biological filter media, allowing them to both intercept particulate matter and cultivate nitrifying bacteria. However, these filters are often complex and inconvenient to maintain. Utility Model Content

DETAILED DESCRIPTION

[0024] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figure 1-2 As shown, this embodiment provides a pneumatic aquarium filtration device, including a filter body 1. The filter body 1 is a cavity structure with an open bottom. A permeable grid plate 2 is provided within the cavity of the filter body 1. The permeable grid plate 2 divides the cavity into upper and lower parts. The upper part can accommodate biochemical filter material 3, and the lower part can accommodate physical filter material 4. Water flows through the bottom of the filter body 1 into the cavity structure, and after being filtered by the physical filter material 4 and the biochemical filter material 3 in sequence, it enters the fish tank. The upper end of the filter body 1 is connected to a pneumatic device, which introduces gas into the fish tank and drives the water flow.

[0027] Specifically, the pneumatic device includes a connecting pipe connected to the filter body 1. The top of the connecting pipe is connected to a water outlet 8, and the water outlet 8 is provided with a water outlet 9 connected to the connecting pipe. After being filtered by the filter body 1, the water flows upward along the connecting pipe and flows into the fish tank through the water outlet 9, completing the filtration cycle.

[0028] The water outlet 8 is provided with a gas supply chamber 10. The bottom end of the gas supply chamber 10 is connected to a lower connector 11, which is connected to a connecting hose 12. The bottom end of the connecting hose 12 is connected to an air stone 13. The gas supply chamber 10 is also connected to an air pipe interface 14. In this embodiment, the air pipe interface 14 is located at the top of the gas supply chamber 10 and is connected to the air pipe through the air pipe interface 14, and then to the air pump to oxygenate the fish tank.

[0029] In addition, the connecting pipe fitting of this embodiment includes a first connecting pipe 5 and a second connecting pipe 6, and the first connecting pipe 5 and the second connecting pipe 6 are connected by a pipe sleeve 7. In this embodiment, the lower part of the first connecting pipe 5 is inserted into the second connecting pipe 6, so that the first connecting pipe 5 can slide up and down inside the second connecting pipe 6, thereby adjusting the overall length of the connecting pipe fitting to accommodate fish tanks of different heights.

[0030] A water inlet grille opening 15 is provided on the lower end wall of the filter body 1 , so that water can flow into the cavity structure from the side of the filter body 1 , thereby increasing the flow rate and improving the filtration speed.

[0031] In addition, the lower end of the filter body 1 is connected to a lower supporting foot 16, which supports the filter body 1. At the same time, the lower supporting foot 16 can form a certain gap between the physical filter material 4 and the bottom of the fish tank. This gap can become a hiding space for small fish and shrimp, providing a protective structure for small fish and shrimp.

[0032] like Figure 3 As shown, a raised tie bar 17 is further provided below the permeable grille plate 2, and the raised tie bar 17 is a discontinuous structure. The structure in which the raised tie bars 17 are separated and not connected to each other can play a role in guiding water flow.

[0033] The gas flow path of this embodiment is ( Figure 2 Straight arrow): Gas is delivered to the tracheal interface 14 by the air pump. The gas passes through the gas supply cavity 10, the lower connector 11, the connecting hose 12, the air stone 13, and enters the cavity of the second connecting pipe 6. The gas then turns upward and enters the fish tank through the water outlet 9, thereby driving the water flow.

[0034] The water flow path is ( Figure 2 Dashed arrow): Driven by the gas flow, the water in the fish tank flows from the bottom of the filter body 1 and the water inlet grille 15 into the cavity structure, and completes physical filtration and biochemical filtration in the cavity in sequence. After that, it passes through the second connecting pipe 6 and the first connecting pipe 5 in sequence, and enters the fish tank from the water outlet 9.

[0035] The pneumatic aquarium filtration device of this embodiment adopts an integrally formed filter body 1, and the inner cavity is divided into two parts by a permeable grid plate 2. The upper part is provided with a biochemical filter material 3 for cultivating nitrifying bacteria, and the lower part is provided with a physical filter material 4 for filtering particulate dirt. The physical filter material 4 is easy to replace and maintain.
