Technical Field
[0001] This utility model relates to the field of aquarium technology, specifically to an integrated filtration system for desktop aquariums. Background Technology
[0002] Desktop aquariums, due to their compact and aesthetically pleasing features, have gradually become a popular decorative element in modern homes and offices. However, limited by their small water volume (typically 5-30L), maintaining water quality faces significant challenges: traditional filtration systems often employ a hybrid physical and biological filtration approach, with filter media and biological filter cotton directly stacked. Water flows through rapidly in a straight path (flow rates often reaching 1-2L / s), causing large particles to easily clog the filter media. Dissolved organic matter, due to insufficient contact time (usually <3 seconds), cannot be fully decomposed, leading to the continuous accumulation of harmful substances such as ammonia nitrogen and nitrite. This necessitates water changes as frequently as 2-3 times per week.
[0003] More seriously, traditional designs lack a dry-wet separation mechanism, causing the filter cotton to be soaked in water for a long time, forming an anaerobic "wet zone," which accelerates the decay of organic matter and breeds harmful bacteria, further exacerbating water quality deterioration.
[0004] In the process of developing this application, the following problems were found with this technology: Existing technologies attempt to improve the purification effect by increasing the volume of filter media or enhancing the power of water pumps, but such solutions significantly increase the size of the equipment and energy consumption (power consumption is generally >10W), making it difficult to adapt to the lightweight requirements of desktop aquariums. In addition, the problem of cross-contamination between filter cotton and biological filter media under DC path has not been solved, the filter media life is shortened by 30%-40%, and the user maintenance cost remains high.
[0005] Therefore, an integrated desktop aquarium filtration system is proposed. Utility Model Content
[0006] The purpose of this invention is to address the problems of existing technologies that attempt to improve purification by increasing the volume of filter media or enhancing the power of water pumps. However, such solutions significantly increase the size of the equipment and energy consumption (generally >10W), making it difficult to meet the lightweight requirements of desktop aquariums. In addition, the problem of cross-contamination between filter cotton and biological filter media in the DC path has not been solved, the filter media lifespan is shortened by 30%-40%, and the user maintenance cost remains high. This invention provides an integrated filtration system for desktop aquariums.
[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0008] A desktop aquarium integrated filtration system includes an aquarium body, characterized in that: a filtration mechanism for purifying the water flow inside the aquarium body is snapped onto the upper end of the aquarium body; an integrated component for integrating equipment placed inside the aquarium body is placed on the bottom of the inner wall of the aquarium body; and a heat dissipation mechanism for ventilating the interior of the aquarium body is sleeved onto the upper end of the aquarium body.
[0009] Furthermore, the filtration mechanism includes a filter chamber, which is snapped onto the upper end of the aquarium body. A filter plate is installed inside the filter chamber, filter cotton is placed on the upper surface of the filter plate, and biological filter media is placed on the bottom of the inner wall of the filter chamber.
[0010] Furthermore, the integrated component includes an integrated compartment placed inside the main body of the aquarium. A side plate is snapped onto the outer end of the integrated compartment. Multiple sets of mounting plates are slidably connected inside the integrated compartment. A water pump is installed inside the top set of mounting plates, and a drain pipe is installed at the drain end of the water pump.
[0011] Furthermore, the heat dissipation mechanism includes multiple sets of fixing plates, which are snapped onto the top of the aquarium body, and multiple sets of heat dissipation fins are rotatably connected inside the fixing plates.
[0012] Furthermore, multiple sets of limiting blocks are installed on the inner wall of the filter chamber, a protective cover is snapped into the inside of the filter chamber, and fixing blocks are symmetrically installed on both sides of the bottom of the filter chamber, with a second protective cover snapped into the inside of each of the two sets of fixing blocks.
[0013] Furthermore, two sets of positioning blocks are installed on the front of the filter chamber, and magnetic blocks are installed inside the positioning blocks and the fixing plate.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. This utility model discharges wastewater accumulated inside the aquarium body through the drain pipe at a flow rate of 0.5L / s to the upper part of the filter cotton by activating the integrated component. This allows the filter cotton to intercept large particles of impurities, thus creating a "dry zone" at the top of the filter cotton. This reduces water quality deterioration caused by the decay of organic matter. As the water flows from the filter plate into the biological filter media, the contact area with air increases threefold, allowing for the isolation of physical and biological filtration of wastewater. This enhances the filtration effect of the filtration mechanism and avoids cross-contamination between the filter cotton and the biological filter media, thereby improving the practicality of the device. The staggered design of the filter cotton and biological filter media forces the water to flow through the filtration mechanism in an "S" shaped path, extending the contact time of wastewater inside the filtration mechanism to twice that of traditional direct-flow filtration mechanisms. This increases the purification efficiency of the filtration mechanism by 40%, thus improving its overall purification efficiency.
[0016] 2. This utility model allows the installation plate, which includes a water pump, wavemaker, germicidal lamp, and heating rod, to be inserted into the integrated compartment by pushing the installation plate. This fixes the water pump, wavemaker, germicidal lamp, and heating rod to the side wall and bottom of the integrated compartment via the installation plate. The power cords of the water pump, wavemaker, germicidal lamp, and heating rod are then routed through a pre-drilled hole on the back of the integrated compartment. This improves the utilization rate of the internal space of the aquarium and reduces the number of internal pipelines, thereby enhancing the visual neatness of the aquarium during use.

[0029] like Figures 1 to 7 As shown, the desktop aquarium integrated filtration system includes an aquarium body 1, a filter mechanism 2 for purifying the water flow inside the aquarium body 1 is attached to the upper end of the aquarium body 1, an integrated component 6 for integrating equipment placed inside the aquarium body 1 is placed at the bottom of the inner wall of the aquarium body 1, and a heat dissipation mechanism 5 for ventilating the interior of the aquarium body 1 is sleeved on the upper end of the aquarium body 1, with the back of the heat dissipation mechanism 5 abutting against the front of the filter mechanism 2. Specifically, when sewage is discharged into the interior of the filter mechanism 2, physical filtration intercepts impurities while biological filtration isolates them, achieving dry and wet separation within the filter mechanism 2 during the filtration process. This enhances the filtration effect of the filter mechanism 2 and avoids cross-contamination between the filter cotton and the biological filter material 203, thus improving the practicality of the device. Through the staggered design inside the filter mechanism 2, the bottoms of boxes A and B are connected but the tops are offset, forcing the water flow through the interior of the filter mechanism 2 in an "S" shaped path. This extends the contact time of sewage inside the filter mechanism 2 to twice that of traditional direct-flow filter mechanisms, thereby increasing the purification efficiency of the filter mechanism 2 by 40%.
[0030] like Figure 2 and Figure 5As shown, the filtration mechanism 2 includes a filter chamber 201, which is snapped onto the upper end of the aquarium body 1. A filter plate 202 is installed inside the filter chamber 201, and filter cotton 204 is placed on the upper surface of the filter plate 202. Biological filter media 203 is placed on the bottom of the inner wall of the filter chamber 201. A groove is provided on the bottom of the inner wall of the filter chamber 201. The position of the groove inside the filter chamber 201 is located at the upper end of the integrated component 6, and the position of the filter cotton 204 is located at the lower end of the drain outlet inside the drain pipe 7.
[0031] Specifically, by activating the integrated component 6, wastewater is discharged through the drain pipe 7 at a flow rate of 0.5 L / s onto the surface of the filter cotton 204. The filter cotton 204 intercepts large particles of impurities, forming a 'dry zone' to reduce water quality deterioration caused by the decay of organic matter. As the water flows from the filter plate 202 to the interior of the biochemical filter media 203, the contact area with air increases by 3 times (dissolved oxygen increases by 1.2 mg / L, providing a more sufficient oxygen environment for nitrifying bacteria). This allows the wastewater to achieve physical filtration to intercept impurities while maintaining biological filtration isolation, thereby enhancing the filtration effect of the filtration mechanism 2 and avoiding cross-contamination between the filter cotton and the biochemical filter media 203, thus improving the practicality of the device. By using a staggered design for the filter cotton 204 and the biochemical filter media 203, the bottoms of boxes A and B are connected but the top surfaces are misaligned, forcing the water flow to pass through the interior of the filtration mechanism 2 in an "S" shaped path. This extends the contact time of the wastewater inside the filtration mechanism 2 to twice that of a traditional direct-flow filtration mechanism, thereby increasing the purification efficiency of the filtration mechanism 2 by 40%.
[0032] Meanwhile, by placing the filter cotton 204 on the upper part of the filter plate 202, the filter cotton 204 can be quickly disassembled, making it convenient for users to quickly disassemble and replace the filter cotton 204 later.
[0033] like Figure 2 , Figure 4 and Figure 7 As shown, the integrated component 6 includes an integrated chamber 601, which is placed inside the aquarium body 1. A side plate 602 is snapped onto the outer end of the integrated chamber 601. Multiple sets of mounting plates 603 are slidably connected inside the integrated chamber 601. A water pump 604 is installed inside the top set of mounting plates 603. A drain pipe 7 is installed at the drain end of the water pump 604. A positioning slot is provided on the side of the integrated chamber 601 away from the internal groove of the filter chamber 201. The side plate 602 is snapped into the positioning slot of the integrated chamber 601. Multiple sets of U-shaped grooves are provided inside the integrated chamber 601. The mounting plate 603 is slidably connected inside the U-shaped grooves of the integrated chamber 601. Multiple sets of drain holes are provided on the lower surface of the drain pipe 7. A wave generator is provided on the outer surface of the integrated chamber 601. A universal adjustment port is installed inside the wave generator.
[0034] Specifically, by pushing the mounting plate 603, the mounting plate 603 containing the water pump 604, wavemaker pump, germicidal lamp, and heater is inserted into the interior of the integrated chamber 601. This allows the water pump 604, wavemaker pump, germicidal lamp, heater, and other equipment to be fixed to the side wall and bottom of the integrated chamber 601 via the mounting plate 603. The power cords of the water pump 604, wavemaker pump, germicidal lamp, heater, and other equipment are then routed through the pre-drilled holes on the back of the integrated chamber 601. This improves the utilization rate of the internal space of the aquarium body 1 and reduces the number of internal pipelines, thereby improving the visual cleanliness of the aquarium body 1 during use. By pushing the two sets of mounting plates 603, the wavemaker pump and water pump 604 are installed diagonally, allowing the water pump 604 and wavemaker pump to form a circulating water flow within the integrated chamber 601, thus avoiding the turbulence caused by the direct spray of water from the tank wall by traditional external wavemakers.
[0035] Meanwhile, the wavemaker pump's inlet is installed inside the wavemaker port, allowing it to work in conjunction with the universal adjustment port during startup. This enables the universal adjustment port to swing within the aquarium body 1, allowing the wavemaker assembly to adjust its direction during use. A UV sterilizer module integrated into the top of the tank allows for sterilization before the water flows out through the drain pipe 7, increasing UV utilization by 25% compared to an external UV sterilizer and effectively reducing bacteria levels in the water. A heater installed at the outer end of the drain pipe 7 heats the water flowing inside during startup, causing the heated water to circulate within the aquarium body 1, thus improving the temperature stability within the aquarium body 1. Figure 7 For reference, from top to bottom are: 604 water pump, wavemaker pump, germicidal lamp and heating rod equipment;
[0036] Furthermore, the side panel 602 is snapped onto the outer end of the integrated compartment 601, allowing the user to manually disassemble and move the side panel 602, thereby enabling the user to quickly pull the mounting plate 603 out of the integrated compartment 601, which facilitates the user to quickly clean the equipment snapped onto the mounting plate 603; the drain pipe 7 is detachable, allowing the user to insert the water inlet pipe to the outer end of the water pump 604, thereby enabling the user to quickly use the water pump 604 to change the water inside the aquarium body 1.
[0037] like Figure 1 and Figure 6As shown, the heat dissipation mechanism 5 includes multiple sets of fixing plates 501. The fixing plates 501 are snapped onto the top of the aquarium body 1. Multiple sets of heat dissipation fins 502 are rotatably connected inside the fixing plates 501. The multiple sets of fixing plates 501 form a U-shaped rectangular frame. The back sides of the two rear sets of fixing plates 501 abut against the front of the filter chamber 201. The fixing plates 501 have slots inside, and through holes are opened on both sides of the inner walls of the slots. The heat dissipation fins 502 are rotatably connected inside the through holes of the fixing plates 501. Specifically, the fixing plates 501 are installed on the upper part of the aquarium body 1 by means of a snap-fit design, so that the fixing plates 501 support the aquarium body 1 during use. The aquarium can be quickly installed and disassembled by hand without the need for additional tools. This allows users to remove a section of the module at any time to feed the fish or observe their condition, reducing the tedious operation of frequently removing the protective cover 4. By increasing or decreasing the number of fixing plates 501 and adjusting the rotation angle of the heat sink 502 to open some ventilation openings, the ventilation volume inside the aquarium body 1 can be flexibly controlled. This allows the ventilation volume inside the aquarium body 1 to adapt to the temperature management needs under different seasons and stocking densities, and significantly increases the air circulation area at the top of the aquarium body 1 to accelerate heat dissipation, thereby minimizing the risk of fish dying from oxygen deficiency or stress due to excessively high water temperature.
[0038] like Figure 1 and Figure 5 As shown, multiple sets of limiting blocks 205 are installed on the inner wall of the filter chamber 201. A protective cover 3 is snapped into the inside of the filter chamber 201. Fixing blocks 206 are symmetrically installed on both sides of the bottom of the filter chamber 201. A second protective cover 4 is snapped into the inside of the two sets of fixing blocks 206. The lower surface of the second protective cover 4 abuts against the upper surface of the heat dissipation mechanism 5, and the lower surface of the first protective cover 3 abuts against the upper surface of the multiple sets of limiting blocks 205. Specifically, by snapping the second protective cover 4 and the first protective cover 3 onto the upper ends of the filter chamber 201 and the heat dissipation mechanism 5 respectively, the first protective cover 3 and the second protective cover 4 cover the opening at the top of the aquarium body 1, thereby minimizing the risk of fish jumping out of the aquarium body 1 to the surface or out of the aquarium body 1, which could lead to suffocation and death of fish, ground pollution, and electrical short circuits.
[0039] like Figure 5 and Figure 6As shown, two sets of positioning blocks are installed on the front of the filter chamber 201. Magnetic blocks 503 are installed inside the positioning blocks and the fixing plate 501. Slots are provided on the inner walls of both the fixing plate 501 and the positioning blocks. The magnetic blocks 503 are installed inside the slots of the fixing plate 501 and the positioning blocks. The magnetic blocks 503 inside the fixing plate 501 are attracted to the outer end of the magnetic blocks 503 inside the positioning blocks. Specifically, by pushing the fixing plate 501, the magnetic blocks 503 inside the fixing plate 501 are attracted to the outer end of the magnetic blocks 503 inside the positioning blocks. Then, by pushing multiple sets of fixing plates 501, multiple sets of magnetic blocks 503 inside the fixing plates 501 are attracted to each other. This restricts the movement of the heat dissipation mechanism 5 on the upper part of the aquarium body 1, thereby minimizing movement of the heat dissipation mechanism 5 in its operating position and improving the stability of the fixing plate 501 during use.
[0040] In summary: By activating integrated component 6, wastewater flows through drain pipe 7 at a rate of 0.5...
[0041] The water is discharged at a flow rate of L / s onto the surface of filter cotton 204. Filter cotton 204 intercepts large particles of impurities, forming a 'dry zone' to reduce water quality deterioration caused by the decay of organic matter. As the water flows from filter plate 202 to the interior of biological filter media 203, the contact area with air increases by 3 times (dissolved oxygen increases by 1.2 mg / L, providing a more sufficient oxygen environment for nitrifying bacteria). This allows the wastewater to achieve physical filtration to intercept impurities while isolating biological filtration, thereby enhancing the filtration effect of filtration mechanism 2 and preventing cross-contamination between the filter cotton and biological filter media 203. To prevent cross-contamination, the mounting plate 603, which contains the water pump 604, wavemaker pump, germicidal lamp, and heater, is inserted into the integrated chamber 601 by pushing the mounting plate 603. This allows the water pump 604, wavemaker pump, germicidal lamp, heater, and other equipment to be fixed to the side wall and bottom of the integrated chamber 601 via the mounting plate 603. The power cords of the water pump 604, wavemaker pump, germicidal lamp, heater, and other equipment are then routed through the pre-drilled holes on the back of the integrated chamber 601. This improves the utilization rate of the internal space of the aquarium body 1 and reduces the number of internal pipelines in the aquarium body 1.
[0042] Meanwhile, by increasing or decreasing the number of fixed plates 501 and adjusting the rotation angle of heat sinks 502 to open some ventilation openings, the ventilation volume inside the aquarium body 1 can be flexibly controlled, so that the ventilation volume inside the aquarium body 1 can adapt to the temperature management needs under different seasons and stocking densities, and significantly increase the air circulation area at the top of the aquarium body 1 to accelerate heat dissipation.
