Description

Technical Field

[0001] The utility model relates to the technical field of fish tanks, in particular to an improvement of a circulating water return fish tank. Background Art

[0002] Currently, most filtered fish tanks on the market have two water pumps: one for pumping filtered water into the filter chamber before it enters the water tank, and the other for pumping water out of the water tank into the main tank, simultaneously performing surfing and oxygenation. This type of design requires both pumps and all other mechanisms to operate during the entire filtration operation of the fish tank. However, depending on the actual application of the fish tank, such as different water pollution levels, the need for surfing, oxygenation, etc., it is not necessary to turn on all water pumps. Currently, if only some functions of the filtered fish tank are turned on, the fish tank will not be able to operate normally.

[0003] When overflowing water from existing fish tanks, most of them are directly grooved on the glass partition, which not only easily causes the glass partition to break, but also the glass partition installed at the bottom of the fish tank is difficult to clean and easily causes clogging.

By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0032] Example 1

[0033] like Figure 1-3 8, the technical solution adopted in this specific embodiment is: according to the embodiment of the utility model, a fish tank circulation return device and a fish tank, which includes a fish tank ornamental tank 1, a filter tank 2, a main partition 3 is provided between the fish tank ornamental tank 1 and the filter tank 2, the front of the main partition 3 is provided with a glue layer 31, the filter tank 2 includes a water suction tank 21, a return water tank 22, a filter tank 23, and a water tank 24, the water suction tank 21, the return water tank 22, the filter tank 23, and the water tank 24 are arranged in sequence The bottoms of the water suction tank 21 and the return water tank 22 are interconnected, and the bottoms of the filter tank 23 and the supply water tank 24 are interconnected; a plurality of water suction hole covers 211 are arranged on the main partition 3 between the water suction tank 21 and the fish tank viewing tank 1, and slots corresponding to the water suction hole covers 211 are opened on the main partition 3. A water suction pump 4 is arranged in the water suction tank 21, and a water sprinkling pipe 5 is arranged on the top of the filter tank 23, and the water sprinkling pipe 5 is connected to the water suction pump 4 through a water pipe 6; a water supply pump 7 is arranged in the supply water tank 24.

[0034] like Figure 1 、 3 As shown in 5-7, the water absorption hole cover 211 is a plastic injection molding one-piece structure, which is simple to process, reduces costs, and reduces the risk of damage to the main partition 3 caused by directly slotting the main partition 3. The edge of the water absorption hole cover 211 is provided with a mounting block 2111 and a fitting surface 2112. The mounting block 2111 is clamped in the slot hole, and an adhesive layer is provided on the fitting surface 2112. It is connected to the main partition 3 through the adhesive layer, which facilitates the installation of the water absorption hole cover 211. The two groups of water absorption hole covers 211 are respectively arranged at the upper part and the middle part of the main partition (3) of the water absorption bin 21. A water absorption trough is arranged below the middle water absorption hole cover 211. The upper water absorption hole cover 211 allows the oil film of the water surface to flow through, the middle water absorption hole cover 211 allows the suspended flow in the water to flow through, and the bottom water absorption hole cover 211 allows large particles and relatively heavy impurities, such as fish feces and fish food residue, to flow through. A grille is provided on the surface of the water absorption hole cover 211.

[0035] like Figure 1-3 As shown, the upper part of the water supply tank 24 is provided with a surfing duckbill 8 connected to the fish tank viewing tank 1, and the surfing duckbill 8 is connected to the water supply pump 7 through a water pipe; the upper part of the surfing duckbill 8 is provided with a Venturi aeration pipe mouth 81.

[0036] like Figure 1-3 As shown, the main partition 3 is made of a shading glass plate. The shading glass plate can play a certain role in blocking light, reducing photosynthesis in the fish tank, thereby reducing the growth of algae. At the same time, it also allows viewers of the fish tank to only see the shading glass plate and not see the water pump, filter, surfing and other components behind the shading glass plate, thereby improving the overall viewing experience for users.

[0037] like Figure 1-3 As shown, the water pipe 6 is provided with a water flow regulating valve 61, which is arranged at the top bend of the water pipe 6. The water flow regulating valve can be provided to adjust the water flow of the water pipe 6, thereby adjusting the water absorption speed. By adjusting the water absorption speed, the overall filtration intensity can be adjusted, and the operating noise of the water absorption pump 4 can also be reduced.

[0038] like Figure 1-3 As shown, a "J"-shaped pipe 25 is provided between the return water tank 22 and the filter tank 23, and the "J"-shaped pipe 25 is suspended on the partition between the return water tank 22 and the filter tank 23. When only the water supply pump 7 is turned on, the water supply pump 7 delivers the filtered water from the water supply tank 24 to the fish tank 1. At this time, the water levels of the water supply tank 24 and the filter tank 23 will drop accordingly. At this time, a "J"-shaped pipe 25 is used to connect the filter tank 23 and the water absorption tank 21, and the water is pumped from the water absorption tank 21 and the return water tank 22 to the top of the pre-physical filter box of the filter tank 23 by using the siphon principle.

[0039] like Figure 1-3 As shown, the "J"-shaped pipe 25 is a retractable water pipe. The retractable water pipe is selected to adjust according to the depth of the cylinder body, because the water pipe needs to be extended to different depths of the return tank 22 cylinder body to pump water, so that water at different depths in the water inlet tank can be pumped to the filter tank, especially the sediment at the bottom can be pumped to the filter tank.

[0040] like Figure 1-3 As shown, the water outlet of the "J"-shaped tube 25 is located above the pre-physical filter box 231 in the filter chamber 23, and the water inlet of the "J"-shaped tube 25 is located in the water absorption chamber 21. The "J"-shaped tube 25 is provided with a water flow regulating valve 61. The water flow regulating valve 61 is located at the top bend of the water pipe 6. The water flow regulating valve can adjust the water flow through the water pipe 6, thereby adjusting the water absorption speed. By adjusting the water absorption speed, the overall filtration intensity can be adjusted, and the operating noise of the water absorption pump 4 can also be reduced.

[0041] like Figure 1-3As shown, a U-shaped groove 221 is provided on the top of the partition between the return water tank 22 and the filter tank 23; a U-shaped groove 221 is provided at the connection between the plastic enclosure and the glass partition. The U-shaped groove 221 can return the water in the filter tank 23 to the return water tank 22 when the filter device in the filter tank 23 overflows due to blockage, ensuring the safety of the entire water and eliminating the hidden danger of water overflowing the fish tank.

[0042] like Figure 1-3 As shown, the filter chamber 23 is provided with a pre-physical filter box 231 and a biochemical filter box 232. The pre-physical filter box 231 is arranged above the biochemical filter box 232, and the pre-physical filter box 231 is arranged below the water spray pipe 5. The water suction pump 4 and the water supply pump 7 can be turned on at the same time. The water suction pump 4 pumps water into the filter chamber 23. After filtration, the water is pumped to the fish tank 5 through the water supply pump 7. The surfing duckbill 8 can be used to form surfing and oxygenation.

[0043] When only one water pump is turned on, the water supply pump 7 is turned on and the water suction pump 4 is turned off. The water suction tank 21 sends water to the filter tank 23 through the water pipe 6 and the water spray pipe 5. At this time, the water levels of the water supply tank 24 and the filter tank 23 will rise accordingly. At this time, the water in the water supply tank 24 flows back to the fish tank viewing tank 1 through the surfing duckbill 8, forming a water circulation.

[0044] The filter tank 2 and the fish tank 1 are either embedded or integrated.

[0045] Example 2

[0046] See Figure 4 This embodiment differs from Example 1 in that a "J"-shaped tube 25 is used in place of the water suction pump 4, water pipe 6, and water spray pipe 5. The water outlet of the "J"-shaped tube 25 is located above the pre-physical filter box 231 in the filter chamber 23, and the water inlet of the "J"-shaped tube 25 is located within the water suction chamber 21. A water flow regulating valve 61 is provided on the "J"-shaped tube 25. Other components and connections are the same as those in Example 1.

[0047] Example 3

[0048] See Figure 8-9The difference between this embodiment and embodiment 1 is that the filter cylinder 2 may also be provided with a hanging wall 26, and the hanging wall 26 is hung on any side of the fish tank ornamental tank 1. Two groups of pipe grooves 261 are provided on the hanging wall 26. The water suction pump 4 is arranged in the fish tank ornamental tank 1, and the water supply pump 7 is connected to the water pipe 6. The water supply pump 7 is arranged in the filter cylinder 2. The other end of the water pipe 6 extends into the fish tank ornamental tank 1 through the pipe groove 261. The water suction pump 4 is connected to the surfing duckbill 8 and extends into the filter cylinder 2. The surfing duckbill 8 is connected to the water spray pipe 5. In this embodiment, there is no need to set a water suction hole cover 211 in the filter cylinder 2. The other components inside the filter cylinder 2 are the same as those in embodiment 1.

[0049] Working principle: The water absorption hole cover 211 is a plastic injection-molded one-piece molding structure, which is simple to process and reduces costs. It also reduces the risk of damage to the main partition 3 caused by direct grooving on the main partition 3. The edge of the water absorption hole cover 211 is provided with a mounting block 2111 and a fitting surface 2112. The mounting block 2111 is clamped in the slot, and an adhesive layer is provided on the fitting surface 2112. It is connected to the main partition 3 through the adhesive layer, which facilitates the maintenance and replacement of the water absorption hole cover 211. When only one water pump needs to be turned on, the water supply pump 7 is turned on and the water absorption pump 4 is turned off. The water absorption tank 21 sends water to the filter tank 23 through the water pipe 6 and the sprinkler pipe 5. At this time, the water levels of the water supply tank 24 and the filter tank 23 will rise accordingly. At this time, the water in the water supply tank 24 flows back to the fish tank viewing tank 1 through the surfing duckbill 8, thereby forming a water circulation.
