Description

Technical Field

[0001] This utility model relates to the field of aquarium water purification and filtration technology, and in particular to a flow-guiding filtration and sedimentation device and a water purification aquarium. Background Technology

[0002] With the increasing popularity of home aquarium keeping and the growing demands for improved living environments for ornamental fish, aquarium water purification systems, as key components for maintaining clean and stable water quality, have become an important research area in the aquarium equipment field. Existing aquarium water purification systems typically use filtration devices to circulate the water, removing suspended impurities, uneaten food, and fish waste, thus preventing turbidity, water deterioration, and even fish diseases. While common filtration devices can achieve physical and biological filtration to some extent, they still have many shortcomings in practical use.

[0003] First, the inlet design of existing filtration devices is relatively simple. Water often flows directly or in a short-circuit manner after entering the filtration area, resulting in a short residence time of water in the filter media. This easily leads to insufficient filtration, especially in separating larger particles and easily settled contaminants, affecting overall water purification efficiency. Second, existing filtration structures lack effective sedimentation and flow guidance designs. The water flow is highly turbulent during inlet, causing suspended impurities to be repeatedly stirred up, making it difficult for them to settle and potentially accelerating filter media clogging, increasing maintenance frequency. Furthermore, the lack of proper separation between the sedimentation zone and the filtration zone allows sediment to be easily carried back into the filtration area by the water flow, reducing the stability of the filtration system. Third, in common aquarium products, top and bottom filters typically require separate filtration designs, resulting in poor structural versatility. This limits user flexibility when installing or changing usage methods, making it difficult to meet the needs of different aquarium sizes and usage scenarios, increasing manufacturing and operating costs.

[0004] In summary, there is an urgent need to provide a flow-guiding filtration and sedimentation device with a reasonable structure, good flow guidance effect, synergistic filtration and sedimentation, and the ability to accommodate both top and bottom filtration methods, as well as a water purification aquarium using this device, in order to overcome the aforementioned defects in the existing technology. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a flow-guiding filtration sedimentation device and a water purification fish tank.

[0006] This utility model is achieved through the following technical solution: A flow-guiding filtration and sedimentation device includes an inlet water zone and a filtration and sedimentation zone. The inlet water zone is a U-shaped water channel and enters the filtration and sedimentation zone by overflow. The filtration and sedimentation zone includes a filter cylinder and an outlet. Water from the inlet water zone enters the filter cylinder and flows out from the outlet after passing through the filter cylinder.

[0007] According to the above technical solution, preferably, a water dividing plate is provided in the water inlet area, and there is a gap between the lower end of the water dividing plate and the bottom surface of the water inlet area. A water inlet is provided on the upper part of the filter cartridge, and the upper end of the water dividing plate is set higher than the water inlet of the filter cartridge.

[0008] According to the above technical solution, preferably, the water divider plate divides the water inlet area into a first zone and a second zone, the second zone being close to the filtration and sedimentation zone, and the volume of the second zone being smaller than that of the first zone.

[0009] According to the above technical solution, preferably, the filtration sedimentation zone further includes an upper partition and a lower partition disposed at the upper and lower ends of the filter cartridge. The upper partition and the lower partition divide the filtration sedimentation zone into a water purification chamber and a sedimentation chamber from top to bottom, and the water outlet is located at the upper part of the water purification chamber.

[0010] According to the above technical solution, preferably, the upper baffle is disposed at the water inlet of the filter cartridge, the bottom of the filter cartridge is provided with a water passage hole, and the lower baffle is disposed at the water passage hole of the filter cartridge.

[0011] This application also discloses a water purification aquarium, including an aquarium body, and the aforementioned flow-guiding filtration and sedimentation device can be used as a top filter or a bottom filter.

[0012] According to the above technical solution, preferably, the flow-guiding filter sedimentation device is located at the upper part of the aquarium body and is connected to the aquarium body through a first water inlet pipe. The first water inlet pipe is located in the first zone of the water inlet area, and its upper part is a bent pipe structure. After the upper part of the first water inlet pipe is bent downward, its opening end is set lower than the water inlet at the upper part of the filter cartridge.

[0013] According to the above technical solution, preferably, the flow-guiding filter sedimentation device is located at the lower part of the aquarium body and is connected to the aquarium body through the second water inlet pipe.

[0014] The beneficial effects of this utility model are: This invention systematically designs the spatial relationship between the water inlet area, the filtration and sedimentation area, and the water outlet structure, making the water flow process continuous and stable, reducing water level fluctuations and noise generation. At the same time, the sedimented impurities are concentrated and easy to clean. The overall structure is compact and easy to maintain, which can significantly improve the user experience and long-term operational stability of the water purification aquarium.

[0015] The device uses a U-shaped water path in the water inlet area and introduces water into the filtration and sedimentation area in an overflow manner, which effectively extends the flow path of the water in the water inlet area. It can form a stable and continuous water flow state after the water level reaches the set height, which is conducive to controlling the water inlet rhythm, reducing system operating noise, and improving the overall stability of operation.

[0016] Meanwhile, by installing a water divider in the inlet area, larger particles of impurities are preferentially settled, reducing the possibility of unsettled impurities directly entering the filter cartridge. Furthermore, the filtration and sedimentation zone is divided into a clean water chamber and a sedimentation chamber by upper and lower partitions, effectively separating the filtered water from the deposited impurities and preventing repeated disturbance of the sediment. This improves the overall filtration and sedimentation effect and reduces maintenance frequency.

[0017] Furthermore, the same flow-guiding filtration and sedimentation device is compatible with both top and bottom filters, eliminating the need to design different filtration structures for different installation methods. This significantly improves the product's versatility and adaptability, reduces manufacturing and user costs, and facilitates its application in aquariums of different sizes and layouts.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0027] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] Example 1: As shown in the figure, this utility model provides a flow guiding filter sedimentation device, including an inlet area 8 and a filter sedimentation area 9. The inlet area 8 is a U-shaped water channel and enters the filter sedimentation area 9 by overflow. In this example, one or more filter sedimentation areas 9 can be arranged side by side. The filter sedimentation area 9 includes a filter cylinder 5 and an outlet 10. The water in the inlet area 8 enters the filter cylinder 5 and flows out from the outlet 10 after passing through the filter cylinder 5.

[0029] The inlet zone 8 is equipped with a water divider plate, with a gap between the lower end of the divider plate and the bottom surface of the inlet zone 8. The filter cartridge 5 has an inlet at its upper part, and the upper end of the divider plate is positioned higher than the inlet of the filter cartridge 5. This design effectively extends the flow path of the water within the inlet zone 8, allowing the water flow to be adequately buffered and evenly distributed before entering the filtration and sedimentation zone 9. The gap between the lower end of the divider plate and the bottom surface of the inlet zone 8 forces a change in direction in the water flow, promoting the preferential settling of larger particles and reducing the load on subsequent filter media, thus extending the service life of the filter media. Simultaneously, the divider plate divides the inlet zone 8 into a first zone 1 and a second zone 2. The second zone 2 is closer to the filtration and sedimentation zone 9, and its volume is smaller than that of the first zone 1. This arrangement effectively accelerates the water flow velocity in the second zone 2, ensuring a stable and continuous water flow after the water level reaches the overflow height.

[0030] In addition, the filtration sedimentation zone 9 also includes an upper partition 7 and a lower partition 4 disposed at the upper and lower ends of the filter cartridge 5. The upper partition 7 and the lower partition 4 divide the filtration sedimentation zone 9 into a clean water chamber 6 and a sedimentation chamber 3 from top to bottom. The outlet 10 is located at the upper part of the clean water chamber 6. Specifically, the upper partition 7 is disposed at the inlet of the filter cartridge 5, and a water passage hole is provided at the bottom of the filter cartridge 5. The lower partition 4 is disposed at the water passage hole of the filter cartridge 5. In actual use, water enters the filtration sedimentation zone 9 from the inlet. During the downward flow due to gravity, the filter cartridge 5 is flushed, which can prevent the filter material from clogging. At the same time, the circulating water creates a downward pressure state, thereby controlling most of the flushed impurities in the bottom sedimentation chamber 3. This structure concentrates the sedimented impurities in the lower sedimentation chamber 3, preventing them from being repeatedly swept up by the circulating water flow. Meanwhile, the water filtered by the filter cartridge 5 flows out from the upper outlet 10.

[0031] Example 2: In the prior art, aquarium filtration methods mainly include top filters and bottom filters. Among them, the top filter structure is mostly set at the top of the aquarium, and the water in the aquarium is pumped to the filter tank by a water pump and then flows back to the aquarium; the bottom filter structure is usually set at the bottom of the aquarium, and the water is circulated and filtered in a multi-stage filter chamber by gravity or a water pump.

[0032] Therefore, this application also discloses a water purification fish tank, including a fish tank body 11, and the aforementioned flow-guiding filtration and sedimentation device 13 can be used as a top filter. Specifically, the flow-guiding filtration and sedimentation device 13 is located at the upper part of the fish tank body 11 and is connected to the fish tank body 11 through a first water inlet pipe 12. The first water inlet pipe 12 is located in the first zone 1 of the water inlet zone 8, and its upper part is a bent pipe structure. After the upper part of the first water inlet pipe 12 is bent downward, its opening end is set lower than the water inlet at the upper part of the filter cartridge 5. This setting makes the water outlet of the first water inlet pipe 12 located below the water level in the water inlet zone 8, effectively reducing system operating noise and improving the overall stability of operation.

[0033] Example 3: This application also discloses a water purification fish tank, including a fish tank body 11, and the above-mentioned flow-guiding filtration and sedimentation device 13 can be used as a bottom filter. Specifically, the flow-guiding filtration and sedimentation device 13 is located at the lower part of the fish tank body 11 and is connected to the fish tank body 11 through a second water inlet pipe 14.

[0034] As can be seen from Examples 2 and 3, the flow-guiding filter sedimentation device 13 provided in this application can be installed on the upper part of the aquarium body 11 as an upper filter or on the lower part of the aquarium body 11 as a bottom filter. There is no need to design different filter structures for different installation methods, which greatly improves the versatility and adaptability of the product, reduces manufacturing costs and user costs, and facilitates its application in aquariums of different sizes and layouts.

[0035] In summary, this application achieves a synergistic effect in guiding flow, filtration, and sedimentation through a systematic design of the water inlet area, filtration and sedimentation area, and water flow path. This overcomes the problems of turbulent water flow, insufficient filtration, unstable sedimentation, and poor structural versatility in existing technologies. It ensures continuous and stable water flow, reduces water level fluctuations and noise generation, and concentrates sediment for easy cleaning. The overall structure is compact and easy to maintain, significantly improving the user experience and long-term operational stability of the water purification aquarium.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
