Description
Technical Field
[0001] This utility model relates to the technical field of aquarium filtration equipment, and in particular to a gas diffusion device for a filtration system. Background Technology
[0002] To maintain water stability in aquariums, most open aquariums typically have a filtration system suspended from the tank wall. The inlet and outlet ports of this filtration system are submerged in the aquarium water. When aquatic plants or other organisms are grown in the aquarium, additional carbon dioxide or oxygen is needed. This technology is applied to the outlet of the filtration system, which has a microporous aeration head that refines the incoming gas into small bubbles, which are carried away by the water flow and dissolve more readily in the aquarium water, resulting in better aquarium aquaculture. However, existing gas diffusion devices lack a check valve, making them prone to backflow and affecting their effectiveness. Furthermore, the cylindrical aeration head of existing gas diffusion devices not only fails to regulate water flow and reduce flow rate but also easily causes localized gas accumulation when the water flows, hindering gas dissolution and diffusion.

Detailed Implementation
[0024] To better understand the technical solution of this utility model, the embodiments provided by this utility model are described in detail below with reference to the accompanying drawings.
[0025] See Figure 1-5 This utility model provides a gas diffusion device for a filtration system, including a base 1. The base 1 is provided with an air inlet 12 and an air outlet 11. The channel formed by the air inlet 12 and the air outlet 11 is designed at an angle. The air inlet 12 is connected to an air inlet connector 3, and the air outlet 11 is connected to an air outlet connector 2. The air outlet end of the air outlet connector 2 is provided with a refining device 4, and the input gas can enter the water body through the refining device 4.
[0026] Optionally, the refining device 4 can be a microporous ceramic sheet or a columnar refining head, etc., and is in the form of a microporous honeycomb. Under pressure, the gas is squeezed to the gas outlet 2 and diffused into tiny bubbles through the refining device 4, which facilitates the dissolution of the gas in water.
[0027] Based on the above embodiments, in other embodiments, the included angle between the channels formed by the air intake interface 12 and the air outlet interface 11 is 0-180 degrees. Preferably, the included angle between the channels formed by the air intake interface 12 and the air outlet interface 11 is a 90-degree vertical design or a 0-degree straight-through design. In this embodiment, the channel formed by the air intake interface 12 and the air outlet interface 11 is designed vertically.
[0028] Based on the above embodiments, in other embodiments, the air outlet end of the air outlet connector 2 is further characterized by a beveled structure.

[0030] In a specific embodiment, see [reference] Figure 7 When the gas diffusion device is installed, the air inlet connector 3 is connected to the air inlet pipe 6, and the air outlet connector 2 is connected to the water outlet pipe. The water outlet pipe includes a vertically designed first water outlet pipe 7 and a second water outlet pipe 8, wherein the water outlets of the first water outlet pipe 7 and the second water outlet pipe 8 are both corresponding to the air outlet connector 2.
[0031] Understandably, Figure 7 The lengths of the air inlet pipe 6, the first water outlet pipe 7, and the second water outlet pipe 8 can be extended indefinitely.
[0032] Therefore, this utility model provides a gas diffusion device for a filtration system. On the one hand, the gas diffusion device is equipped with a check valve, which effectively prevents water backflow when the device stops supplying gas, thus avoiding water backflow into the air inlet pipe and damaging the gas source equipment. On the other hand, the gas diffusion device adopts a sloping air outlet connector, which not only allows for rotational adjustment of the air outlet connector angle to regulate and control the water flow, but the sloping structure also effectively reduces gas accumulation, making it more conducive to gas dissolution and effective diffusion. The gas passes through the air inlet connector and the air outlet connector in sequence, diffuses into the water through the microporous atomizing plate, and is carried by the water flow to the aquarium. The entire device has a simple structure, is directly connected to the air inlet pipe and the water outlet pipe, is compact and does not take up much space, further improving the aesthetics and stability of the device.

[0037] Optionally, the connection between the air outlet connector 2 and the base 1 can be a threaded connection or other similar connection method.
[0038] Based on the above embodiments, in other embodiments, the end of the air outlet connector 1 near the air outlet end is further provided with a third annular groove 23, and the third annular groove 23 is provided with a second sealing ring 25. The second sealing ring 25 achieves the fixation of the air outlet connector 1 and the first water outlet pipe 7 of the filter system through axial interference fit, and achieves the sealing effect when the air outlet connector 2 is connected to the first water outlet pipe 7.
