Description

TECHNICAL FIELD

[0001] The utility model relates to a filter bucket, especially to a filter bucket outside fish tank. BACKGROUND

[0002] In recent years, with the improvement of people's living quality, ornamental fish farming has gradually become a popular leisure way. In order to ensure the healthy growth of ornamental fish, water quality management becomes particularly important, and the performance of aquarium filter as the key equipment for water purification directly affects the stability of the environment in the aquarium and the survival quality of ornamental fish. The common filter on the market mainly includes built-in and external types. The built-in filter is directly installed in the aquarium, although it is easy to install, but it has the problems of large space occupation and affecting the ornamental effect. More importantly, due to the limited volume, the capacity of the filter material is limited, which cannot meet the high requirements of water quality in large aquariums or mixed breeding of multiple varieties.

[0003] As an effective alternative, the external filter bucket solves the problem of space occupation of the built-in filter by placing the filter device outside the aquarium, and also provides the possibility to improve the filtering efficiency. The external filter bucket usually has a larger volume and can accommodate more filter materials, thereby realizing more thorough physical filtration, chemical adsorption and biological degradation, and providing a continuous and stable clean water source for the aquarium.

[0004] Although the existing external filter bucket products solve the problem of space occupation of the built-in filter to some extent and provide better filtering effect, they still face many challenges and limitations, which limit their wider promotion and application.

[0005] On the one hand, the design of many external filter buckets lacks scientific and reasonable water flow path planning. Specifically, after the water flow enters the filter bucket, due to the lack of effective guiding mechanism, the water flow distribution is extremely uneven, the water flow speed in some areas is too fast, and the water quality cannot be fully contacted with the filter material, thereby reducing the physical filtration effect, while in other areas, the water flow speed is too slow or even stagnant, which not only wastes the effective area of the filter material, but also easily forms dead angles and becomes a breeding ground for bacteria. In the long run, not only will it affect the efficiency of the entire filtration system, but also may have a negative impact on the ecological environment in the aquarium.

[0006] On the other hand, the structure of the partial external filter barrel is too complex, which brings great inconvenience to the daily maintenance of the user. The complex structure not only increases the difficulty of initial installation, so that many users have to seek help from professionals, but also makes the subsequent cleaning and replacement of filter material extremely cumbersome. For example, when the inside of the filter barrel needs to be cleaned regularly or the filter material needs to be replaced, the user often needs to spend a lot of time and effort to disassemble, and sometimes even needs to completely empty the water in the filter barrel, which undoubtedly increases the maintenance cost. In addition, the complex structure may also be one of the reasons for frequent failures. Once a failure occurs, it is also difficult to repair.

[0007] Based on the in-depth analysis of these problems, the present application proposes targeted improvement measures, aiming to provide a more efficient, convenient and economical external filtration solution for users. Content of the utility model

[0036] Fish manure separator 6 is arranged in bucket body 1, and fish manure separator 6 has water inlet end 7 and water outlet end 8, and the water inlet end 7 of fish manure separator 6 is communicated with water inlet pipe 4;

[0037] Water isolation cover 9 is fixed at the bottom of containing cavity 3, and inner ring 10 is coaxially arranged in water isolation cover 9, and first passageway 11 and second passageway 12 that are independent of each other are arranged between inner ring 10 and water isolation cover 9, first passageway 11 is communicated with water outlet end 8 of fish manure separator 6, and second passageway 12 is communicated with containing cavity 3;

[0038] The purifying mechanism 13 comprises a purifying cylinder 14 and a purifying assembly 15 arranged in the purifying cylinder 14, and a guide channel 16 is arranged in the accommodating cavity 3, the purifying cylinder 14 is inserted into the guide channel 16, and a water diversion gap 17 in communication with the first channel 11 is formed between the outer wall of the purifying cylinder 14 and the inner wall of the guide channel 16, a water diversion hole 18 in communication with the water diversion gap 17 is arranged on the side wall of the upper portion of the purifying cylinder 14, and a water outlet hole 19 in communication with the second channel 12 is arranged on the lower portion of the purifying cylinder 14;

[0039] The filter bins 20 are arranged in multiple layers in the accommodating cavity 3.

[0040] The water pump 21 is arranged on the bucket cover 2, the inlet of the water pump 21 is in communication with the accommodating cavity 3, and the outlet of the water pump 21 is in communication with the water outlet pipe 5.

[0041] In the second embodiment, the filter bin 20 comprises a surrounding plate 22, a filter grid 23 and a guide cylinder 27, the filter grid 23 is fixed to the lower end of the surrounding plate 22, a plurality of through slots 24 are arranged on the filter grid 23, a placing cavity 25 is formed between the surrounding plate 22 and the filter grid 23, a filter assembly 26 is arranged in the placing cavity 25, and the guide cylinder 27 is arranged in a penetrating manner, the guide cylinder 27 of the upper filter bin 20 is inserted into the guide cylinder 27 of the lower filter bin 20 when the filter bins 20 are arranged in multiple layers, and the guide channel 16 is formed.

[0042] The filter bin 20 improves the overall performance and stability of the fish tank filter system, specifically, the placing cavity 25 formed by the surrounding plate 22 and the filter grid 23 provides a stable installation space for the filter assembly 26, the design of the plurality of through slots 24 ensures uniform distribution of water flow, maximally improves the filtering efficiency, and the filter assembly 26 can be replaced flexibly according to different purifying requirements, such as activated carbon, biological ceramic rings, ion exchange resins, etc., to realize fine and multi-level water quality purification.

[0043] The purpose of the guide cylinder 27 is to effectively achieve physical isolation between different filtering systems by forming independent guide channels 16, preventing the direct mixing of purified water bodies with water to be purified, thereby ensuring that each filtering bin 20 can perform specific filtering functions. When multiple filtering bins 20 are stacked vertically, the guide cylinder 27 of the upper filtering bin 20 is precisely inserted into the guide cylinder 27 of the lower filtering bin 20, not only forming a continuous guide channel 16, but also constructing a tight water flow transmission system. Within the guide channel 16, water can only continue to be filtered by the purification assembly 15, and outside the guide channel 16, water bodies can pass through each filtering bin 20 in turn, with each layer being able to complete corresponding purification treatment according to its specific filtering assembly 26, without contact with the water body in the guide channel 16. This design not only improves the systematicness and accuracy of the filtering, but also effectively avoids cross-contamination of different stage filtering media, maximizing the continuity and thoroughness of water quality purification.

[0044] Preferably, the upper end of the guide cylinder 27 is higher than the upper end of the surrounding plate 22, the outer side wall of the guide cylinder 27 is vertically provided with a limiting rib 28, and the inner wall of the bottom of the guide cylinder 27 has a limiting groove 29 matched with the limiting rib 28. When multiple filtering bins 20 are stacked vertically, the limiting rib 28 of the lower filtering bin 20 is clamped into the limiting groove 29 of the upper filtering bin 20.

[0045] In the above structure, the upper end of the guide cylinder 27 is higher than the surrounding plate 22, the outer side wall is provided with a limiting rib 28, and the bottom inner wall has a matching limiting groove 29. This limiting mechanism provides an extremely precise and stable connection scheme for the stacking assembly of the filtering bin 20. When multiple filtering bins 20 are stacked vertically, the limiting rib 28 of the lower filtering bin 20 is precisely clamped into the limiting groove 29 of the upper filtering bin 20, not only achieving precise positioning between the filtering bins 20, but also effectively preventing the filtering bins 20 from loosening or shifting in the vertical direction. The design of the guide cylinder 27 being higher than the surrounding plate 22 further enhances the stability of the stacking process, ensuring that each filtering bin 20 can be docked to form a continuous and sealed water flow transmission system.

[0046] This structural design not only greatly improves the accuracy and reliability of assembly, but also simplifies the installation and disassembly process of the filtering bin 20. Users can easily adjust and replace the filtering bin 20 according to actual needs, achieving quick and convenient maintenance. At the same time, this tight connection mechanism can effectively reduce the bypass and leakage of water flow at the connection of the filtering bin 20, further ensuring the overall performance and efficiency of the water quality purification system.

[0047] Preferably, the purification assembly 15 comprises a central tube 30 and a filter cotton 31, the bottom of the purification cylinder 14 is provided with a positioning column 32, the positioning column 32 is provided with a positioning hole 33 penetrating upward and downward, the lower end of the central tube 30 is inserted into the positioning hole 33, and a plurality of water filtering holes 34 are formed in the side wall of the central tube 30, the filter cotton 31 is sleeved on the central tube 30, and the lower end of the positioning column 32 extends out of the purification cylinder 14 and is located in the inner ring 10, so that the positioning hole 33 communicates with the second channel 12.

[0048] In the above structure, the positioning hole 33 on the positioning column 32 provides an accurate installation position for the central tube 30, ensuring that the central tube 30 can be stably and vertically arranged in the purification cylinder 14, and the design of the plurality of water filtering holes 34 in the side wall of the central tube 30 can uniformly disperse the water flow, significantly improving the filtering efficiency, and the filter cotton 31 sleeved on the central tube 30 can not only trap small impurities but also deeply adsorb and filter harmful substances in the water.

[0049] The lower end of the positioning column 32 extends out of the purification cylinder 14 and is located in the inner ring 10, thereby realizing the direct communication of the positioning hole 33 with the second channel 12, so that the treated water body can flow smoothly and orderly to the next processing link. This structural design not only ensures the continuity and stability of the water flow, but also maximizes the thoroughness and efficiency of water quality purification through accurate positioning and multi-layer filtration, providing a healthier and cleaner water quality guarantee for the fish tank ecological environment.

[0050] Example Three: As shown in the figure, different from Example Two, the purification assembly 15 comprises a UV sterilization lamp 35 fixed in the purification cylinder 14.

[0051] In this structure, the purification assembly 15 adopts the form of UV sterilization, and the UV sterilization lamp 35 can effectively kill pathogens, bacteria and microorganisms in the water. By using the high-energy radiation of ultraviolet light to directly damage the DNA structure of microorganisms, the reproduction and growth of microorganisms are blocked, achieving complete microbial disinfection, providing a healthier and cleaner water environment for the fish tank ecological system, greatly reducing the risk of fish diseases, and reducing the need for the use of chemical disinfectants.

[0052] Example Four: As shown in the figure, different from Example Two, the lower end of the purification cylinder 14 is provided with a blocking ring 36, and the inner wall of the blocking ring 36 is in close contact with the outer wall of the inner ring 10.

[0053] The above design not only prevents the water flow from bypassing or leaking between the purification cylinder 14 and the inner ring 10, but also ensures that the water body must pass through the predetermined purification path, maximizing the purification efficiency. The close fit of the blocking ring 36 and the inner ring 10 forms a nearly sealed transition area, effectively blocking the irregular diffusion of the water flow, guiding the water body to pass through each purification link along the predetermined optimal path, making the entire filtration process more efficient and stable.

[0054] In the fifth embodiment, as shown in the figure, the first channel 11 is provided with a switching seat 37 between the water outlet end 8 of the fish waste separator 6, the switching seat 37 has a first passage and a second passage inside which are independent of each other, and a switching valve 38 is further arranged on the switching seat 37, which can be switched between a first position and a second position. In the first position, the switching valve 38 connects the first passage with the water outlet end 8 of the fish waste separator 6, and in the second position, the switching valve 38 connects the second passage with an external sewage pipe 41.

[0055] The above structure can accurately control the discharge path of the water flow by arranging the first passage and the second passage inside the switching seat 37 which are independent of each other, and providing the switching valve 38 which can be switched between two positions, so as to realize efficient treatment of fish waste and impurities. In the first position, the switching valve 38 ensures that the water body is directly connected to the water outlet end 8 of the fish waste separator 6 through the first passage, and continues the subsequent purification treatment; and in the second position, the switching valve 38 immediately guides the water flow into the external sewage pipe 41, quickly discharges the deposited fish waste and impurities, without the need to disassemble the filter device complicatedly.

[0056] This design not only greatly simplifies the fish tank maintenance process, but also effectively prevents the long-term accumulation of fish waste in the system, reduces the risk of water quality deterioration, and provides a more efficient and sanitary filter system solution for aquarium enthusiasts, greatly improving the management convenience and cleanliness of the ecological environment of the fish tank.

[0057] Preferably, a sewage pipe 39 is arranged on the side wall of the barrel body 1 and communicates with the containing cavity 3, and an adjusting valve 40 is installed on the sewage pipe 39, and the sewage pipe 39 communicates with the sewage pipe 41.

[0058] In the above structure, the sewage pipe 39 arranged on the side wall of the barrel body 1 introduces a key sewage discharge channel for the filter system, and the adjusting valve 40 installed on the sewage pipe 39 provides a more delicate and flexible control mechanism for fish tank maintenance. This design allows users to accurately adjust the flow and speed of sewage discharge, and accurately control sewage discharge when cleaning fish tank sediments or performing regular maintenance, avoiding the problems of water flow impact or poor sewage discharge that may occur in traditional methods.

[0059] The sewage pipe 39 directly communicates with the sewage pipe 41, ensuring that the sewage can be quickly and completely discharged from the system, greatly simplifying the cleaning process, and effectively preventing the accumulation of sewage in the filter system, reducing the risk of bacterial growth and water quality deterioration.

[0060] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made according to the content of the present application specification and drawings, is also included in the patent protection scope of the present application.
