Description

Technical Field

[0001] This utility model relates to the field of aquarium technology, and in particular to a self-cleaning aquarium that is easy to maintain. Background Technology

[0002] As people's living standards improve, keeping pets has become an important way to regulate emotions and alleviate loneliness, and more and more people are choosing to keep pets. Ornamental fish, as a pet with low barriers to entry and easy care, are becoming increasingly popular. People usually keep ornamental fish in aquariums for easy viewing and care; however, existing aquariums still have some drawbacks in practical use:

[0003] On the one hand, during the rearing process, leftover food, fish excrement, and solid impurities such as withered aquatic plants accumulate at the bottom of the tank and cannot be removed by the filtration system. These accumulated solid impurities pollute the water quality. Existing aquariums usually do not have a drainage system and can only clean the impurities at the bottom of the tank and change the liquid by removing the ornamental fish. However, removing the ornamental fish inevitably causes injury to them, increasing the loss of the fish.

[0004] On the other hand, deposited impurities constantly react with microorganisms in the water to produce harmful substances such as ammonia nitrogen and nitrite, thus polluting the water and affecting the health of ornamental fish. Nitrifying bacteria can convert harmful substances into less toxic or non-toxic substances, thereby achieving self-purification of the aquarium water. For this reason, people usually lay structures such as volcanic rock at the bottom of the tank to promote the growth of nitrifying bacteria. However, nitrifying bacteria cannot survive in flowing water and must rely on structures such as volcanic rock to reproduce in large quantities. The activities of ornamental fish and the operation of the filtration system keep the water in the tank constantly flowing, making it difficult for nitrifying bacteria to colonize and reproduce.

[0005] Therefore, how to design an easy-to-maintain self-cleaning aquarium that can not only easily and quickly clean impurities from the bottom of the tank, but also achieve self-cleaning of the water inside the tank, thus eliminating the need for frequent water changes, is a technical problem that designers and developers need to solve.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] This utility model provides an easy-to-maintain self-cleaning fish tank 10, which not only allows for convenient and quick cleaning of impurities at the bottom of the tank, but also enables the self-cleaning of the water inside, thus eliminating the need for frequent water changes. Figure 1 and Figure 2 As shown, the easy-to-maintain self-cleaning fish tank 10 includes a tank body 100, a waste drainage and bacteria cultivation device 200, and a base 300. The tank body 100 and the waste drainage and bacteria cultivation device 200 are both located on the base 300.

[0033] Among them, such as Figures 1 to 4 As shown, the tank body 100 has an internal storage space 110 for storing water and housing ornamental fish. Preferably, the tank body 100 has a cylindrical structure. A drain outlet 120 is provided at one end of the tank body 100, and an inclined surface 130 is formed between the drain outlet 120 and the side wall of the tank body 100, forming an obtuse angle. Thus, the inclined surface 130 effectively guides residual food, fish excrement, and solid impurities such as withered aquatic plants to the drain outlet 120, thereby enabling the drain outlet 120 to collect solid impurities and preventing ornamental fish from coming into contact with these impurities and causing bacterial infections.

[0034] Preferably, such as Figure 4As shown, a window 140 is provided at the end of the tank body 100 away from the drain port 120, and a rubber ring 150 is provided at the edge of the window 140. Users can feed ornamental fish through the window 140, and the rubber ring 150 can protect users from being scratched by the sharp edges of the tank body.

[0035] like Figure 2 , Figure 3 and Figure 5 As shown, the wastewater discharge and bacterial cultivation device 200 includes a cultivation base 210, a water pipe 220, and a switch 230. The cultivation base 210 is connected to the wastewater outlet 120, and a water passage 211 is provided in the center of the cultivation base 210. The water pipe 220 is located between the cultivation base 210 and the switch 230, and the water pipe 220 is connected to the receiving space 110 through the water passage 211. The switch 230 is located at the end of the water pipe 220 away from the cultivation base 210, and the switch 230 is used to control the water flow. When the switch 230 is turned on, the water pipe 220 is connected to the outside, thereby allowing the water in the tank to be discharged to the outside. In some embodiments, the switch 230 is a faucet, which facilitates user operation. Of course, the switch 230 can also be other structures, such as a knob.

[0036] Preferably, such as Figure 3 and Figure 5 As shown, the wastewater discharge and bacteria cultivation device 200 includes a filter plate 250, which is placed over the water passage 211. In this way, the filter plate 250 allows impurities to pass through while blocking ornamental stones, aquatic plants, ornamental fish, etc. in the tank, preventing them from being discharged to the outside.

[0037] During cleaning, the user only needs to turn on switch 230. Under the action of gravity, the impurities in the tank will pass through the drain port 120, water passage 211, and water pipe 220 along with the water in the tank, and finally be discharged to the outside through switch 230. The ornamental stones, aquatic plants, ornamental fish, etc. in the tank are retained in the tank due to the isolation effect of filter plate 250. Then, the user can add clean water to the tank through window 140 to complete the cleaning.

[0038] It's important to note that sediment deposited in the tank constantly reacts with microorganisms in the water to produce harmful substances such as ammonia and nitrite, polluting the water and affecting the health of ornamental fish. Nitrifying bacteria can convert these harmful substances into less toxic or non-toxic ones, thus achieving self-purification of the tank water. For this reason, people usually place structures like volcanic rock at the bottom of the tank to encourage the growth of nitrifying bacteria. However, nitrifying bacteria cannot survive in flowing water; they must attach to structures like volcanic rock to multiply rapidly. The activity of ornamental fish and the operation of the filtration system keep the water in the tank constantly flowing, making it difficult for nitrifying bacteria to colonize and reproduce.

[0039] Therefore, such as Figure 3 and Figure 5 As shown, the culture base 210 has a culture space 212 around the water passage 211, and the culture space 212 is connected to the containment space 110. Users can place carriers such as volcanic rocks and quartz balls, which are easy for nitrifying bacteria to attach to, into the culture space 212. The water in the culture space 212 flows slowly or is even in a stagnant state, thus providing a stable breeding environment for nitrifying bacteria.

[0040] It should be emphasized that, compared with the prior art, the easy-to-maintain self-cleaning fish tank 10 of this utility model has the following advantages:

[0041] Firstly, users only need to turn on switch 230 to clean impurities in the tank and replace the water. The operation is convenient and will not harm the ornamental fish, thus reducing the loss of ornamental fish.

[0042] Secondly, the 212 culture space can provide a stable breeding environment for nitrifying bacteria, thereby purifying the water quality through the large-scale reproduction of nitrifying bacteria and maintaining the stability of the water quality. As a result, users do not need to clean and change the water frequently, which improves the user experience.

[0043] Thirdly, the tank body 100 has a cylindrical structure, which improves space utilization compared to a rectangular fish tank of the same volume. Compared to traditional fish tanks, it occupies 3 / 1 of the usable space, making it easier for users to place, and it is also suitable for small spaces.

[0044] Furthermore, such as Figure 3 and Figure 5 As shown, the wastewater discharge and bacterial cultivation device 200 includes a partition plate 240, which covers the bacterial cultivation space 212. The partition plate 240 has multiple through holes 241, which connect the bacterial cultivation space 212 to the receiving space 110. The through holes 241 are evenly spaced around the center of the partition plate 240. This further reduces the impact of water flow within the tank on the water in the bacterial cultivation space 212, making the water in the space approximately still. This facilitates the large-scale reproduction of nitrifying bacteria, while allowing water to still flow between the receiving space 110 and the bacterial cultivation space 212 through the through holes 241, without affecting the nitrifying bacteria's purification effect on the water.

[0045] In actual use, such as Figure 5As shown, the bottom of the tank is usually lined with ornamental stones or other structures to enhance its aesthetics. If these structures are located above the through-hole 241, they will block it, hindering water flow between the culture space 212 and the container space 110, thus affecting the purification effect of nitrifying bacteria on the water in the container space 110. To avoid this problem, this invention provides multiple strip grooves 242 on the partition plate 240, with through-holes 241 located within them. Each strip groove 242 corresponds to one through-hole 241. Thus, even if ornamental stones or other structures are placed above the through-hole 241, they will not block it, allowing water to still flow between the container space 110 and the culture space 212, thereby ensuring the purification effect of nitrifying bacteria on the water.

[0046] In some embodiments, such as Figure 3 and Figure 6 As shown, the base 300 includes a connecting seat 310 and a mounting hole 320. The drain port 120 is detachably disposed within the mounting hole 320 via the connecting seat 310, thereby facilitating the user's assembly and disassembly of the cylinder body 100. Furthermore, the outer wall of the connecting seat 310 extends outward to form a retaining portion 311, and the wall of the mounting hole 320 extends inward to form a boss 321 that mates with the retaining portion 311. Thus, the cylinder body 100 can be installed simply by aligning the connecting seat 310 with the mounting hole 320 and inserting it. Disassembly is achieved by pulling the connecting seat 310 out of the mounting hole 320, making the assembly and disassembly operations convenient and the structure simple.

[0047] Furthermore, the inner wall of the connecting seat 310 is provided with an internal thread, and the outer wall of the drain port 120 is provided with an external thread that mates with the internal thread. The drain port 120 is detachably connected to the connecting seat 310 through the engagement of the internal and external threads. The detachable connection between the drain port 120 and the connecting seat 310 via the threaded structure effectively ensures the sealing of the connection between the drain port 120 and the connecting seat 310, thereby preventing water leakage. It is also convenient and quick to assemble and disassemble, and the drain port 120 is not easy to loosen automatically during use. At the same time, the structure is simple and easy to process.

[0048] In some embodiments, a sealing element (not shown) is provided between the drain outlet 120 and the culture base 210, and the sealing element is in a compressed state after the drain outlet 120 is installed relative to the culture base 210. This effectively ensures the sealing of the connection between the drain outlet 120 and the culture base 210, preventing leakage and improving the user experience. Preferably, the sealing element can be a rubber sealing ring. Rubber sealing rings are low in cost and easy to install. Alternatively, the sealing element can be a silicone sealing ring, a closed-cell sponge rubber ring 150, a neoprene rubber ring 150, or a sealing ring made of other materials. The sealing element can also be formed by applying silicone rubber to the outer wall of the drain outlet 120 for sealing.

[0049] In summary, the self-cleaning fish tank 10 of this utility model is easy to maintain, which can not only conveniently and quickly clean the impurities at the bottom of the tank, but also achieve self-cleaning of the water in the tank, thus eliminating the need for frequent water changes.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
