Description

Technical Field

[0001] This utility model relates to the field of water system device technology, specifically an ecological water system device for aquariums. Background Technology

[0002] An aquarium, also known as an aquarium tank, is a container used to keep aquatic life. It is usually made of glass or acrylic and has aesthetic value. They not only add life and color to homes or commercial spaces, but also serve as a way to relax and relieve stress.

[0003] An aquarium is more than just a simple container; it is a small artificial ecosystem that, through careful design and maintenance, can create a beautiful and harmonious underwater world.

[0004] Modern aquariums are often equipped with functional components such as filtration systems, thermostats, and lighting, which are essential for maintaining water quality, regulating water temperature, and promoting plant growth.

[0005] A marine aquarium, also known as a saltwater fish tank or marine aquarium, is an aquarium used to keep and display marine life. Compared to ordinary aquariums, marine aquariums have higher requirements for the ecosystem. They not only need to provide a living space that simulates the natural environment for marine life, but also need to establish an effective biological filtration system by adding live rock, live sand, etc., to promote the growth of beneficial bacteria and maintain the balance of water quality.

[0006] Therefore, many users often find it impossible to keep marine life in conventional aquariums due to insufficient water flow or chaotic ecosystems. This is especially true for small aquariums, such as those used in homes or office desks. Marine life in these aquariums frequently suffers from various diseases and becomes unstable, which has hindered the widespread adoption of marine aquarium keeping and severely restricted the industry's development.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-12An aquarium ecological water system device includes a device body 100, which includes a shell. The shell has an internal cavity. An inlet 121 and an outlet 122 are provided on the cavity wall, penetrating the shell and communicating with the internal space of the cavity. At least a first partition 101 and a second partition 102 are provided within the cavity. The first partition 101 and the second partition 102 sequentially divide the inlet 121 and outlet 122 into a first sinking cavity 111, a second sinking cavity 112, and a rising cavity 113. The inlet 121 is located at the upper end of the first sinking cavity 111 and communicates with it. A water supply channel 123 is provided between the first sinking cavity 111 and the second sinking cavity 112, enabling water circulation between them. The lower inlet 1231 of the 23-section is connected to the bottom of the first submerged cavity 111. The upper outlet 1232 of the upper water channel 123 is connected to the upper end of the second submerged cavity 112. The lower end of the second partition 102 is provided with a water passage hole 124, which enables water passage between the second submerged cavity 112 and the rising cavity 113. The outlet 122 is located at the upper end of the rising cavity 113 and is connected to the interior of the rising cavity 113. The first submerged cavity... A primary filtration chamber 114 is provided at the upper end of 111 below the water inlet 121. A primary filtration support 131 is provided inside the primary filtration chamber 114. The primary filtration support 131 includes a primary filtration upper shell 1311 and a primary filtration lower shell 1312 that are connected to each other. A filtration chamber is formed between the primary filtration upper shell 1311 and the primary filtration lower shell 1312. Water purification material is detachably placed inside the filtration chamber. Both the primary filtration upper shell 1311 and the primary filtration lower shell 1312 are hollow shells.

[0034] In this embodiment, the water inlet channel 123 is formed by a first partition 101 and a third partition 103. The lower end of the first partition 101 forms the lower water inlet 1231 between the lower end of the first partition 101 and the bottom surface of the cavity. The upper end of the third partition 103 is set below the horizontal plane of the water inlet 121, forming the upper water outlet 1232. One or more second sinking cavities 112 and / or rising cavities 113 may be added between the second sinking cavity 112 and the rising cavity 113. The added second sinking cavities 112 and rising cavities 113 may be arranged in a mixed manner. The added second sinking cavity 112 includes the water supply channel 123 and is connected to the adjacent second sinking cavity 112 or rising cavity 113 through the water supply channel 123. The more second sinking cavities 112 and / or rising cavities 113 are set, the longer the aquatic ecosystem will be through the connection of the water supply channel 123, and the number of compartments in the biological filtration system will also increase. This is conducive to further improving and enriching the ecological chain and is more suitable for the breeding of diversified marine organisms.

[0035] The upper end of the cavity is set as an open cavity opening, and multiple installation notches are provided at the edge of the cavity opening. The installation notches include wiring notches 133, clamping notches 134 and bolt notches 135. The wiring notches 133 can facilitate the wiring and power connection of electrical equipment placed in the cavity to the outside of the cavity. The clamping notches 133 can be used as the mounting position for lighting products. The bolt notches 135 are used for bolt fixing. For example, supplementary lights and protein separators can be stably installed at the edge of the cavity opening through the bolt notches 135.

[0036] like Figure 5 and Figure 11 As shown, a fourth partition 104 is provided inside the rising cavity 113. A light source cavity 116 is formed between the fourth partition 104 and a portion of the wall of the rising cavity 113, which is isolated from the rising cavity 113. The fourth partition 104 is a transparent plate. An algae lamp plate can be installed inside the light source cavity 116. The algae cultivated in the rising cavity 113 can photosynthesize through the light from the algae lamp plate, thereby promoting the growth of algae and absorbing and purifying NO3 mixed in the water.

[0037] like Figure 5As shown, a fifth partition 105 is provided inside the first settling cavity 111. The fifth partition 105 and a portion of the wall of the first settling cavity 111 form a sedimentation chamber 115, which is isolated from the first settling cavity 111. The inlet 121 is located within the sedimentation chamber 115. An inner inlet pipe 125 is connected to the inner side of the inlet 121, extending below the water level in the sedimentation chamber 115. An overflow outlet 132 is provided at the upper end of the fifth partition 105. The overflow outlet 132 is located at the upper end of the primary filtration chamber 114 and is lower than the top edge of the chamber. When the water pump is working, it directs water flow from the inlet 121. An inner water inlet pipe 125 is introduced into the sedimentation chamber 115. Heavier impurities, such as fine sand, carried into the sedimentation chamber 115 by the water flow will first settle at the bottom of the chamber due to their greater density than water, thus completing the filtration of these heavier impurities. The water accumulates in the sedimentation chamber 115. When the chamber is full, the water can flow through the overflow port 132 into the primary filtration chamber 114. As the water flows through the primary filtration chamber 114, some lighter impurities with larger particles will be filtered out again by the filter cotton inside, preventing them from entering the next filtration stage.

[0038] The outlet 122 is connected to an outlet pipe 127 on the outside, and the inlet 121 is connected to an inlet pipe 126 on the outside. A water pump is connected to the end of the inlet pipe 126 away from the inlet 121. A water outlet buffer 128 can be selectively provided between the outlet and the outlet pipe. The water outlet buffer 128 can accumulate and buffer the water flow at the outlet 121 to ensure the continuity of the water flow and a large water output, ensure that the water level is stable, and also reduce water flow noise.

[0039] like Figure 11 As shown, a water outlet filter plate 129 is provided on the inner side of the water outlet 122 at the lower end of the water outlet 122. When the rising chamber 113 is used to cultivate seaweed and other organisms, the water outlet filter plate 129 plays the role of preventing aquatic organisms from floating up and blocking the water outlet 122.

[0040] One side of the outer wall of the shell is provided with an outwardly extending protrusion 136. The protrusion 136 is provided with a cylinder through hole 1364 penetrating the upper and lower end faces of the protrusion 136. Since this ecological water circuit device is usually placed next to the aquarium 200 for use, the setting of the protrusion 136 is very important. The protrusion 136 extends into the aquarium 200 in orientation, so that some extensions can enter the aquarium 200 with the cooperation of the protrusion 136. For example, when using a water replenisher, the water replenisher can be fixedly supported on the protrusion 136, and the water replenishment pipe can be extended into the aquarium 200 through the cylinder through hole 1364 to achieve water replenishment connection. As another example, when using a chiller thermostat, the inlet and outlet pipes of the chiller thermostat can be extended into the water inside the aquarium 200 through the cylinder through hole 1364.

[0041] The lower edge of the left and / or right side of the extended protrusion 136 is provided with a wiring hole 137. Since electrical equipment such as water pumps and wavemakers need to be installed inside the aquarium 200, the wiring hole 137 is provided for these electrical equipment to run wires to the outside of the aquarium for power connection. If there is no wiring hole 137, the wires will run out from the edge of the aquarium 200, which will cause the aquarium cover to not close tightly.

[0042] The lower end of the extended protrusion 136 is provided with a downwardly extending water pump protective baffle 1365. The water pump protective baffle 1365 is provided with baffle water permeable holes 1366. Aquariums 200 are generally decorated with sea sand or kept with aquatic organisms. These may enter the water pump and affect its normal operation. The function of the water pump protective baffle 1365 is to prevent such substances from entering the water pump.

[0043] The water pump protective baffle 1365 is detachably connected to the extended protrusion 136, such as Figure 1 As shown, the extended protrusion 136 extends downward and is provided with a connecting part. A bolt through hole is provided on the wall of the connecting part. A bolt adjustment groove 1368 is provided at the upper end of the water pump protective baffle 1365. A tightening bolt 1367 can be used to pass through the bolt adjustment groove 1368 and the bolt through hole. When the tightening bolt 1367 is tightened, the water pump protective baffle 1365 can be fixedly installed on the extended protrusion 136. When it is necessary to disassemble and install the water pump, the tightening bolt 1367 can be loosened to remove the water pump protective baffle 1365, so as to facilitate the disassembly and assembly of the water pump. The bolt adjustment groove 1368 can be slid up and down to adjust the length of the water pump protective baffle (1365) extending into the aquarium 200.

[0044] An anti-jumping line 138 is provided on the outer wall of the shell below the extension protrusion 136. The anti-jumping line 138 extends along the length of the extension protrusion 136. When the device body 100 is combined with the aquarium 200, if the alignment is not particularly precise, there may be a gap between the aquarium 200 and the shell of the device body 100. When fish jump over, they may fall into the gap. In this case, if it is not detected in time, the fish will most likely die from lack of oxygen due to being out of the water. Therefore, the anti-jumping line 138 is designed to block the possible gap and prevent the fish from encountering the aforementioned risks.

[0045] The extended protrusion 136 includes a protrusion support frame 1361 and a protrusion panel 1363, wherein the protrusion panel 1363 is detachably connected to the protrusion support frame 1361 via a positioning and fastening mechanism 1362. Figure 1 As shown, the positioning and fastening mechanism 1362 includes a snap hole on the protrusion support frame 1361 and a snap key on the protrusion panel 1363. The snap key is obscured by the protrusion panel 1363, but its shape can be a cuboid that matches the shape of the snap hole. When the protrusion panel 1363 is installed on the protrusion support frame 1361, the snap hole and the snap key are engaged. Figure 7 As shown, the positioning and fastening mechanism 1362 includes an "I"-shaped fastener on the protrusion support frame 1361 and a "U"-shaped fastener on the protrusion panel 1363. When the protrusion panel 1363 is installed on the protrusion support frame 1361, the "I"-shaped fastener and the "U"-shaped fastener are fastened together.

[0046] Example of using the standard version of the ecological water system device: With the device body 100 not connected to the protruding panel 1363, place the device body 100 as follows... Figure 6 As shown, the device is placed close to the aquarium 100, so that the extended protrusion 136 extends into the inside of the aquarium 200. Then, the inlet pipe 126, the water pump, and the outlet pipe 127 are installed. Next, the protrusion panel 1363 is installed on the extended protrusion 136. At this point, the assembly of the device body 100 and the aquarium 200 is completed.

[0047] like Figure 5As shown, an inner water inlet pipe 125 is installed inside the sedimentation chamber 115 from the cavity opening. Next, a moistened bacterial culture medium is placed in the first lower sedimentation chamber 111. The bacterial culture medium can be porous and highly permeable nano-bricks. After the nano-bricks are stacked, a primary filter support 131 containing water purification materials is installed in the primary filter chamber 114. The water purification materials are conventionally filter cotton boards. Then, phosphorus-absorbing beads and activated carbon, among other water purification materials, are placed in the second lower sedimentation chamber 112. A protein skimmer is simultaneously installed above the second lower sedimentation chamber 112, making the second lower sedimentation chamber 112 the first chamber for deep water purification. Algae and aquatic organisms can be placed in the rising chamber 113. Simultaneously, an algae lamp plate is installed in the light source chamber 116, with the light emission direction of the algae lamp plate facing... The rising chamber 113 is set up. Then, the input and input pipes of the constant temperature chiller are extended into the aquarium through the cylinder through hole 1364 on the extension protrusion 136. Finally, purified water is injected into the chamber and the aquarium 200. The power supply of each electrical device is turned on and the electrical device starts to operate. At this time, when the water pump works, the water in the aquarium 200 is first pumped into the sedimentation chamber 115 from the water inlet 121. After the sedimentation chamber 115 is full, it automatically overflows from the overflow 132 into the primary filter chamber 114. Then, the water flows into the first sinking chamber 111 under the action of gravity, and then enters the second sinking chamber 112 through the water inlet channel 123. Then, it enters the rising chamber 113 from the water outlet 124. Finally, the water flows back into the aquarium 200 from the water outlet 122 to complete one water circulation. In this process, the primary filtration chamber 114 first filters the water flowing into the chamber, removing various coarse impurities. Beneficial bacteria are injected into the bacterial culture medium in the first sinking chamber 111, along with bacterial culture nutrient solution, allowing the bacteria to infiltrate and develop within the bacterial culture medium. The bacterial culture medium is located at the bottom of the first sinking chamber 111, and the water flow over its surface creates a low-pressure environment inside, providing a favorable environment for bacterial growth. During the growth process, some bacteria seep out from the surface of the bacterial culture medium into the water flow, circulating together in the ecological waterway. During this circulation, various purification zones and filter materials are set up to absorb and treat harmful bacteria, while beneficial bacteria are ultimately delivered to the aquarium 200 for aquatic organisms to absorb. Because multiple ecological containment zones are planned along the entire waterway, various ecological culture or filter materials with different functions can be scientifically arranged to meet the needs of various types of ecosystems, thus establishing an ecosystem suitable for the stable survival of aquatic organisms throughout the waterway circulation.

[0048] In summary, this invention, within a relatively limited cavity space, rationally divides the area into multiple sub-cavities using partitions. These sub-cavities allow for the partitioning and sequential management of the ecosystem, providing ample and reasonable space for complex biological filtration systems. They also effectively regulate and extend the direction and course of the ecological waterways, promoting the growth of beneficial bacteria, maintaining water quality balance, and ensuring the long-term stability of the marine aquarium's ecosystem. This provides a strong foundation and guidance for users raising marine life, and is expected to lead the marine aquarium aquaculture industry into a phase of sustainable and healthy development.
