Abstract
Description
Technical Field
[0001] This utility model relates to a fish tank, and more particularly to a multifunctional fish tank. Background Technology
[0002] An aquarium is a transparent water container used to raise ornamental fish, primarily made of glass, with common types including bent glass and ultra-clear glass. The tank shape is typically rectangular or cubic, with the material chosen based on the needs of the fish being kept; for example, glass is often used for aquatic plants. Bent glass aquariums are made by bending the glass into a curved shape, but large tanks pose safety hazards, as long-term use may increase the risk of bursting due to pressure and temperature changes. Ultra-clear glass aquariums are a common choice for home aquarium keeping due to their superior light transmittance and, when the thickness and manufacturing process meet standards, their safety. Fire safety tips advise against placing aquariums in direct sunlight, as the light refraction through the water can cause a focusing effect and potentially lead to a fire. Traditional aquariums are primarily used as containers, with few products enhancing their functionality. Most enhancements are achieved by adding accessories such as lights and aerators. While these additional features are convenient, compatibility between different functions is often limited, leaving significant room for optimization to significantly improve the overall effect.

[0015] Figure 3 This is an exploded bottom view of the structure of this utility model. Detailed Implementation
[0016] like Figures 1-3As shown, a multifunctional fish tank includes a tank body 1, which further comprises a top cover 2, a middle cylinder 3, and a base 4. The middle cylinder 3 contains a water storage chamber. The top cover 2 has two mounting grooves, a first groove 5 and a second groove 6, extending into the water storage chamber. A housing sleeve 7 with aquatic plants is fitted and fixed in the first groove 5, and a filter sleeve 8 is fitted and fixed in the second groove 6. An auxiliary sleeve 9 is fixedly mounted on the filter sleeve 8. The auxiliary sleeve 9 has an oxygenation component 10 and a power component 11. A circulating oxygen supply path is formed between the auxiliary sleeve 9, the filter sleeve 8, and the water storage chamber. The filter sleeve 8 has at least one filter layer. The removable housing sleeve 7, filter sleeve 8, and auxiliary sleeve 9 facilitate regular cleaning or replacement, effectively extending the equipment's service life. After being purified by the filter layer, the water flows back to the water storage chamber. Combined with the rotation of the waterwheel, the dissolved oxygen content is increased, and the water flow is circulated, maintaining the water in a clean and oxygen-rich state. The plant roots extend naturally within the housing 7, continuously absorbing impurities such as nitrates from the water, further stabilizing the aquatic ecosystem. Modules are secured by flanges 13 and grooves 12, allowing for easy assembly and disassembly and simple maintenance. A USB-powered light source provides illumination for nighttime viewing and also assists in plant photosynthesis. The overall structure is compact and the functions are highly efficient and coordinated, suitable for small-scale aquatic ecosystem maintenance needs in homes, offices, and other settings. During circulation, the water undergoes multi-layer filtration and purification, effectively removing suspended solids and organic pollutants. Combined with continuous oxygenation by the aerator 10, it maintains the dissolved oxygen concentration required for fish survival. Within the housing 7, the plants absorb nutrients such as nitrogen and phosphorus from the water through their roots, inhibiting excessive algae growth and enhancing ecological stability. Each functional module is independently molded and quickly connected via clips 18 and grooves 17 during assembly, facilitating disassembly, cleaning, or component replacement. Water is pumped up and released down at the aerator 10, providing rotational power for it. The rotating waterwheel, driven by the water flow, creates a natural aeration effect, increasing the surface area of the water in contact with air and thus effectively improving oxygen dissolution efficiency. The lighting inside the aquarium provides supplemental illumination, both for photosynthesis and for enhancing visual appeal. The rotating waterwheel is not only aesthetically pleasing but also symbolizes "water brings wealth," and it further aids in filtration.
[0017] Both mounting slot 5 and mounting slot 6 have a retaining groove 12 at the outer edge of the slot opening, and both the receiving sleeve 7 and the filter sleeve 8 have a flange 13 at the top outer edge. The flange 13 and the retaining groove 12 are engaged and limited. This facilitates production and installation, ensures that each module is stable and does not loosen during use, and allows users to easily disassemble and maintain it by hand. The mating structure of the flange 13 and the retaining groove 12 also effectively prevents water leakage and improves sealing performance. The overall design balances functionality and aesthetics, with a reasonable layout of each component, high space utilization, and adaptability to placement needs in different scenarios.
[0018] At least one of the top cover 2, the middle cylinder 3, or the base 4 is equipped with a light source, which is powered via a USB interface and a 5-volt power supply. It features low power consumption and high reliability, suitable for long-term continuous operation. The light source uses LED cold light sources, providing soft and uniform light, effectively reducing the impact of heat radiation on water temperature and preventing stress reactions in fish due to localized heating. The light wavelength is optimized to balance aesthetics and plant growth needs, promoting photosynthetic efficiency and enhancing nighttime visibility. The power supply interface is highly versatile, compatible with various power sources such as power banks, computers, or chargers, offering flexible and convenient use. Combined with a timer socket, it can also automate lighting, further enhancing the level of intelligent maintenance.
[0019] The receiving sleeve 7 has evenly distributed ventilation holes 14 in the center of its bottom surface, and an opening groove 15 near the outer edge of its bottom surface. The opening groove 15 is evenly spaced along the circumferential path of the outer edge. This ensures that water can smoothly enter the receiving sleeve 7 from multiple directions, improving the uniformity of water intake and filtration efficiency. The ventilation holes 14 and the opening groove 15 work together to ensure the oxygen needed for plant root respiration while preventing water accumulation at the bottom and the formation of an anaerobic zone, effectively inhibiting the growth of harmful bacteria. This structure also facilitates the drainage of residual water during disassembly, reducing the risk of secondary pollution during maintenance. The overall layout fully considers water flow, plant growth needs, and user operation convenience, achieving a high degree of unity between ecological balance and practicality.
[0020] The filter sleeve 8 has filter holes 16 evenly spaced on its bottom surface. The spacing is related to the filtration accuracy and depends on actual production needs; therefore, it will not be elaborated upon or limited here. The auxiliary sleeve 9 has a flange 13 corresponding to the filter sleeve 8 on its inner side. Both the filter sleeve 8 and the auxiliary sleeve 9 have several evenly arranged through grooves 17 at their flanges 13. The auxiliary sleeve 9 also has a buckle 18 on its bottom surface, which secures it to the through grooves 17 of the filter sleeve 8. This allows for quick assembly and disassembly and a stable connection, effectively preventing loosening or detachment due to vibration or water flow impact during use. The mating structure of the through grooves 17 and flanges 13 further enhances the sealing between components, preventing unfiltered water from leaking out. The auxiliary sleeve 9 has an integrally extended seat 19 at its flange 13, on which the aerator 10 is movably mounted. In this embodiment, the rotating waterwheel can be directly placed on the groove of the seat 19, but this is not the only option. The power component 11 is a lifting water pipe with a water pump, and the oxygenation component 10 is a rotating waterwheel. This is one that is relatively easy to implement and meets the design requirements, but it is not the only limitation.
