Description

Technical Field

[0001] This utility model relates to the field of aquarium filtration technology, and in particular to a waterfall-style aquarium filtration device. Background Technology

[0002] An aquarium is a transparent container used to keep ornamental fish, aquatic plants, and small aquatic organisms. It is commonly made of glass or acrylic, offering good light transmission and water resistance. It is not only a common decorative item in homes and offices but also a miniature representation of aquatic ecosystems.

[0003] Currently, aquarium water purification mainly relies on built-in or external filtration devices. Although these devices can achieve basic physical interception and biological filtration, their water output methods are mostly straight pipe outlets or simple diffusion, without adopting a waterfall-style water flow structure that simulates a natural ecosystem. The small contact area and short contact time between water and air result in insufficient reoxygenation capacity of the water, easily leading to low dissolved oxygen levels, which is not conducive to the survival of fish and nitrifying bacteria. The lack of a vertically cascading water curtain design weakens the water's flow and circulation efficiency, easily creating filtration dead zones and reducing the overall purification effect. Traditional water outlet methods lack the dynamic aesthetics of natural waterscapes and cannot create the visual and auditory enjoyment of a cascading waterfall, reducing the aquarium's ornamental value and ecological atmosphere.

[0004] Therefore, a waterfall-style aquarium filtration system needs to be designed to solve the aforementioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing aquarium filtration devices, which mostly use straight pipes or diffused water outlets and are not waterfall-style structures, resulting in small contact area with air, insufficient dissolved oxygen, poor water circulation, easy dead zones, reduced purification effect, and lack of visual and auditory aesthetics of natural waterscapes, affecting the ornamental value and ecological atmosphere, this utility model provides a waterfall-style aquarium filtration device.

[0006] Technical Solution: A waterfall-style aquarium filtration device includes an aquarium body, a guide plate, a first filter canister, a drain pipe, a water pump, a second filter canister, a purification component, and a filtration component. The guide plate is placed on one side of the top of the aquarium body, and a water outlet is fixedly installed at the front of the guide plate. The first filter canister is placed on one side of the top of the guide plate, and the bottom of the first filter canister is connected to and communicates with the drain pipe. The bottom of the drain pipe extends into the aquarium body and is connected to and communicates with the water pump, which is placed inside the aquarium body. A first horizontal groove is formed on the right side of the first filter canister. The second filter canister is placed on the other side of the top of the guide plate, and a second horizontal groove is formed at the front of the second filter canister. A purification component is installed inside the first filter canister, and a filtration component is installed at the front of the guide plate.

[0007] To further explain, the inside of the guide plate has a V-shaped bevel.

[0008] To further clarify, the aquarium body, the first filter canister, and the second filter canister are all made of ceramic.

[0009] To further explain, the purification assembly includes a first filter frame, a second filter frame, a third filter frame, a fourth filter frame, and filter cotton. The first filter frame, the second filter frame, the third filter frame, and the fourth filter frame are placed inside the first filter tank from top to bottom. Filter cotton is placed inside the fourth filter frame. The first filter frame, the second filter frame, the third filter frame, and the fourth filter frame are interconnected.

[0010] To further explain, the filter assembly includes a filter frame, a filter screen, filter paper, and a pull rod. The filter frame is placed in front of the flow guide plate, the filter screen is fixedly connected inside the filter frame, the filter paper is placed inside the filter frame, and the pull rod is fixedly connected to the front of the filter frame.

[0011] To further clarify, the filter frame is located at the front of the second filter tank.

[0012] To further explain, it also includes a blowout preventer. The blowout preventer is fixedly connected to the bottom of the first filter tank. The blowout preventer has multiple through holes on its exterior, which are connected to the drainage pipe.

[0013] To further explain, it also includes an elastic rope, which is fixedly connected to the rear of the flow guide plate. The elastic rope can be snapped into the edge of the rear side wall of the aquarium body.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention adopts a double-filter waterfall water flow setting. The first filter tank and the second filter tank are respectively set with a first horizontal groove and a second horizontal groove to form a two-stage waterfall water flow, which significantly increases the contact area between the water and the air. During the process of the water overflowing from the horizontal groove and falling, full aeration and oxygenation are achieved, which effectively solves the problem of insufficient dissolved oxygen in traditional straight pipe water outlet. At the same time, the natural kinetic energy generated by the waterfall water flow promotes the circulation of water inside the aquarium, avoids the occurrence of purification dead corners, and significantly improves the overall water purification effect.

[0015] 2. This utility model achieves efficient water treatment through multi-layer graded filtration. After the water pump delivers the water to the first filter tank, it passes through the filter cotton of the fourth filter frame for preliminary physical filtration, the biochemical cotton of the third filter frame for secondary filtration and biological culture, the quartz balls of the second filter frame and the nanoballs of the first filter frame for deep biochemical purification, and finally the filter paper in the filter frame for fine filtration. This multi-stage synergistic filtration method ensures thorough removal of impurities, stable operation of the nitrification system, and significantly improves water purification efficiency and system stability.

[0016] 3. This utility model combines a ceramic filter tank with a flow guide plate, along with a setting for planting hydroponic plants, to achieve water purification while creating a natural ecological landscape. The waterfall not only provides visual beauty but also produces a pleasant natural flowing water sound effect. The anti-spray cover effectively suppresses water splashing, the elastic rope fixing device ensures stable operation, and the V-shaped inclined flow guide design allows the water flow to concentrate and fall smoothly back from the outlet bucket.

Detailed Implementation

[0025] Example: A waterfall-style aquarium filter device, such as... Figures 1-8As shown, the aquarium includes a fish tank body 1, a flow guide plate 2, a first filter canister 3, a drain pipe 4, a water pump 401, a second filter canister 12, a first filter frame 5, a second filter frame 6, a third filter frame 7, a fourth filter frame 8, filter cotton 11, a filter frame 14, a filter screen 15, filter paper 16, and a pull rod 17. The flow guide plate 2 is placed on the rear top of the aquarium body 1. The bottom of the flow guide plate 2 has a V-shaped slope. A water outlet is fixed on the front of the flow guide plate 2. The first filter canister 3 is placed on the top left side of the flow guide plate 2. The bottom of the first filter canister 3 is connected to and connected to the drain pipe 4. The bottom end of the drain pipe 4 extends into the aquarium body 1 and is connected to and connected to the water pump 401. The water pump 401 is placed on the bottom side of the aquarium body 1. A first horizontal groove is opened on the upper right side of the first filter canister 3. 10. A second filter canister 12 is placed on the top right side of the flow guide plate 2. The aquarium body 1, the first filter canister 3, and the second filter canister 12 are all made of ceramic. A second horizontal groove 13 is opened on the upper front side of the second filter canister 12. The first filter canister 3 has a first filter frame 5, a second filter frame 6, a third filter frame 7, and a fourth filter frame 8 placed inside from top to bottom. The fourth filter frame 8 contains filter cotton 11. The first filter frame 5, the second filter frame 6, the third filter frame 7, and the fourth filter frame 8 are interconnected. A filter frame 14 is placed on the front right side of the flow guide plate 2. The filter frame 14 is located in front of the second filter canister 12. A filter screen 15 is installed on the bottom side of the filter frame 14 by screws. Filter paper 16 is placed inside the filter frame 14. A pull rod 17 is welded to the front side of the filter frame 14.

[0026] like Figure 4 and Figure 8 As shown, it also includes a blowout preventer 9 and an elastic rope 18. The blowout preventer 9 is fixedly connected to the bottom of the first filter tank 3. The side wall of the blowout preventer 9 has multiple through holes that communicate with the drainage pipe 4. The rear side of the guide plate 2 is fixedly connected to the elastic rope 18, which can be inserted into the edge of the rear side wall of the aquarium body 1.

[0027] When this device is needed, hydroponic plants can be placed inside the first filter tank 3 and the second filter tank 12. First, the water pump 401 is started. The water pump 401 pumps the water from the bottom of the aquarium body 1 upward through the drain pipe 4. The water flow is evenly dispersed through the through hole and enters the first filter tank 3. The anti-splash cover 9 effectively prevents water from splashing directly onto the top of the tank, ensuring that the water flows smoothly into the first filter tank 3. The water first passes through the filter cotton 11 in the fourth filter frame 8. The filter cotton 11 performs preliminary physical filtration of coarse impurities in the water. Then, the water flows upward through the bio-cotton in the third filter frame 7. The bio-cotton filters out fine impurities. Simultaneously, it provides an attachment site for nitrifying bacteria, continuing to flow upwards through the quartz balls in the second filter frame 6 and the nanospheres in the first filter frame 5. These two layers of biochemical filter media effectively decompose harmful substances in the water by cultivating a large number of nitrifying bacteria, completing the biological purification process. After multi-layer purification, the water reaches the top of the first filter tank 3 and overflows from the first horizontal groove 10, forming the first waterfall flow into the second filter tank 12. The second filter tank 12 receives the water flow from the first waterfall. After a brief accumulation in the tank, the water overflows from the second horizontal groove 13, forming the second waterfall flow. This water flow falls downwards into the filter frame 14, where the filter paper 16 performs... After final fine filtration, the water quality is further ensured by the filter screen 15. The filtered clean water flows smoothly back into the aquarium body 1, forming a complete water circulation system. During this process, the elastic rope 18 can be firmly locked into the rear edge of the outer wall of the aquarium body 1 to ensure the overall stability of the device. The water overflowing from the top of the first filter tank 3 and the second filter tank 12 flows into the guide plate 2. The V-shaped slope inside the guide plate 2 can guide the water flow to the middle, so that it flows into the aquarium body 1 from the outlet. After the work is completed, the water pump 401 is turned off to stop the water circulation. The user can remove the filter frame 14 from the guide plate 2 by pulling the lever 17 upwards. After removing and cleaning the internally contaminated filter paper 16, the first filter frame 5, second filter frame 6, third filter frame 7, and fourth filter frame 8 in the first filter tank 3 can be removed sequentially upwards for periodic cleaning or filter media replacement. After cleaning, the first filter frame 5, second filter frame 6, third filter frame 7, and fourth filter frame 8 are placed back into the first filter tank 3 in the order from top to bottom. The guide plate 2 is pushed back to its original position by the pull rod 17. Finally, the elastic rope 18 is confirmed to be securely fixed, and the device is ready for the next start-up. Through the above process, this device achieves integrated and efficient operation from physical filtration, biological purification to water circulation.
