Description

Technical Field

[0001] The utility model belongs to the field of fish tank oxygen supply, in particular to a fish tank oxygen supply device. Background Art

[0002] Oxygen supply in fish tanks is a key link in maintaining the health and stability of the fish tank ecosystem. By injecting oxygen into the water, it can promote the breathing of fish and support their normal physiological activities. However, in modern fish tank designs, designers often choose to fix the oxygen outlet at a specific position. However, this fixed oxygen outlet position is inconvenient to adjust in actual use. When the layout in the fish tank changes, such as adding new decorations, changing the arrangement of aquatic plants, or changing the activity area of ​​​​fish, the fixed oxygen outlet cannot flexibly adapt to these changes and cannot provide sufficient oxygen support for the new demand area. Furthermore, if there is a local water quality problem in the fish tank, such as the accumulation of pollutants or bacterial growth in a corner, since the oxygen outlet position cannot be moved, it is difficult to increase the oxygen supply in the area in a targeted manner to promote beneficial biochemical reactions and improve water quality. In summary, the design of the fixed and inconvenient oxygen outlet position of the fish tank oxygen supply device has many inconveniences and defects in actual application. In order to solve this problem, we need to develop a fish tank oxygen supply device. Utility Model Content

[0024] A threaded rod 9 is installed above the top plate 8, and a linkage ring 10 is connected above the threaded rod 9. A top block 15 is connected above the linkage ring 10 through a connecting rod 11. A sliding hole 16 is opened in the middle of the top block 15, and a hollow sleeve rod 12 is provided in the sliding hole 16. An extension rod 13 is respectively installed on the front and rear sides of the hollow sleeve rod 12, and a rotating pulley 14 is respectively installed at the front end of the two extension rods 13.

[0025] The inner wall of the linkage ring 10 and the inner wall of the bottom ring 6 are both provided with internal threads, the outer wall of the connecting ring 5 is provided with external threads, and the threaded rod 9 and the linkage ring 10 are rotatably connected through the threads.

[0027] The diameter of the upper end of the truncated cone-shaped cylinder 22 is smaller than that of the lower end thereof, and the inlet 23 is communicated with the interior of the activated carbon filter cartridge 4 .

[0028] The rear ends of the two extension rods 13 extend into the interior of the hollow sleeve rod 12 respectively, and the threaded rod 9 is made of stainless steel.

[0029] The output end of the small motor 19 is connected to the upper end of the rotating rod 20, and the connecting rod 11 is an L-shaped structure.

[0030] See also Figure 1 、 Figure 3 as well as Figure 4 As a first embodiment of the present invention: in actual use, the two extension rods 13 are pulled to extend or shorten them, and their use length is adjusted according to the width of the fish tank, so that the two rotating pulleys 14 are respectively placed on the upper edge of the fish tank, and then the activated carbon filter cartridge 4 is put into the fish tank. The threaded rod 9 can be rotated to make it rise and fall in the linkage ring 10 to adjust the descending height of the activated carbon filter cartridge 4. After the adjustment is completed, the oxygen pump 1 can be started. The oxygen pump 1 can transmit oxygen to the intake pipe 3 through the oxygen supply telescopic hose 2, and then the oxygen enters the fish tank through the intake pipe 3. To supply oxygen to the fish tank, when the oxygen supply position needs to be adjusted, the two extension rods 13 can be pushed by the hollow sleeve rod 12, so that the two rotating pulleys 14 can move laterally along the upper edge of the fish tank, thereby driving the air inlet pipe 3 to move laterally in the fish tank to adjust the air outlet position.

The small motor 19 can drive the rotating plate 21 to rotate through the rotating rod 20, thereby generating a negative pressure inside the activated carbon filter cartridge 4. Due to the pressure difference, the fish food and fish excrement at the bottom of the fish tank are sucked into the truncated cone-shaped cylinder 22 through the inlet 23. Since the diameter of the upper end of the truncated cone-shaped cylinder 22 is smaller than the diameter of the lower end, the fish food and excrement are not easy to leak out when entering. The porous structure of the activated carbon filter cartridge 4 can absorb and filter impurities, odors and harmful substances in the water, allowing the water to be discharged through the activated carbon filter cartridge 4. After being filtered, the fish food and excrement remain inside the activated carbon filter cartridge 4, thereby achieving water purification. Before cleaning, the height of the activated carbon filter cartridge 4 can be adjusted by rotating the threaded rod 9 in accordance with the first embodiment. During the cleaning process, the activated carbon filter cartridge 4 can also be driven to move back and forth and laterally in accordance with the first embodiment, thereby achieving all-round cleaning of the bottom of the fish tank.
