Description

Technical Field

[0001] This utility model relates to the field of aquarium purification technology, specifically to a circulating filtration structure and an aquarium. Background Technology

[0002] Fish tanks are often placed in offices or homes as decorative items to improve the quality of the work and living environment. However, during the process of raising aquatic plants and animals in the fish tank, a large amount of algae will grow on the inner wall of the tank due to photosynthesis, which will have a significant impact on the aesthetic appeal of the fish tank.

[0003] Currently, common aquarium filtration systems on the market typically employ back filters, bottom filters, top filters, and side filters, resulting in significant homogenization and a lack of diversity in filtration structure, which fails to guarantee filtration effectiveness. Furthermore, the mainstream traditional aquarium design remains pure glass tanks, with a few manufacturers merely altering the outer shell material to create a different visual effect. However, due to limitations in traditional glass bonding manufacturing processes, the bonding of multiple glass panels carries the risk of delamination, tank breakage, and water leakage.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

By setting up a multi-stage filtration system, it differentiates itself from conventional back filters, bottom filters, top filters, and side filters, effectively ensuring filtration performance. Furthermore, this invention also provides a fish tank based on the aforementioned circulating filtration structure, ensuring effective filtration of the water inside the tank.

[0006] This utility model is achieved through the following technical solution:

[0033] Example

[0034] like Figure 2-3 As shown, this utility model embodiment provides a circulating filtration structure, including: a filtration unit, the filtration unit including: a primary filter box 110, the bottom plate of the primary filter box 110 having a first through hole; a secondary filter box 120, the secondary filter box 120 being vertically spaced relative to the primary filter box 110, the primary filter box 110 communicating with the secondary filter box 120 through the first through hole, the bottom plate of the secondary filter box 120 having a second through hole; a tertiary filter box 130, the tertiary filter box 130 being horizontally spaced relative to the secondary filter box 120, the bottom plate of the tertiary filter box 130 having a third through hole, the second through hole and the third through hole cooperating to achieve communication between the secondary filter box 120 and the tertiary filter box 130; and a water storage unit 140, the water storage unit 140 being horizontally spaced relative to the tertiary filter box 130, the top of the tertiary filter box 130 and the water storage unit 140 communicating with each other through an overflow trough.

[0035] It should be noted that, as should be known by those skilled in the art, the primary filter box 110, the secondary filter box 120, and the tertiary filter box 130 are all used to filter water, and filter media can be provided in the primary filter box 110, the secondary filter box 120, and the tertiary filter box 130 to ensure the filtration effect.

[0036] The secondary filter box 120 is vertically spaced relative to the primary filter box 110. Therefore, the water to be filtered can be transferred from the primary filter box 110 to the secondary filter box 120 under the action of gravity, completing the first filtration. Due to the setting of the tertiary filter box 130, the water to be filtered can be transferred from the bottom of the secondary filter box 120 to the tertiary filter box 130, completing the second filtration. An overflow trough is set at the top of the tertiary filter box 130, and the water can be transferred to the water storage unit 140 through the overflow trough to complete the water storage.

[0037] It should be noted that, regarding the structural design of the overflow tank, a surrounding lip is designed on the top of the three-stage filter box 130, which is adapted to the top of the water storage unit 140. This effectively prevents water flow from scouring the gap between the three-stage filter box 130 and the water storage unit 140, and also reduces the risk of water splashing. At the same time, the lip designed for the outlet of the three-stage filter box 130 is flush with the side of the water storage unit 140, allowing the water to slide in along the side of the water storage unit 140, avoiding the phenomenon of water being thrown out after entering the water storage unit 140, thereby further reducing the noise generated by the water flow.

[0038] In this scheme, the circulating filtration structure includes a filtration unit, which includes a primary filter box 110, the bottom plate of which has a first through hole; a secondary filter box 120, which is vertically spaced relative to the primary filter box 110, and the primary filter box 110 communicates with the secondary filter box 120 through the first through hole, the bottom plate of which has a second through hole; a tertiary filter box 130, which is horizontally spaced relative to the secondary filter box 120, and the bottom plate of the tertiary filter box 130 has a third through hole, the second and third through holes cooperating to achieve communication between the secondary filter box 120 and the tertiary filter box 130; and a water storage unit 140, which is horizontally spaced relative to the tertiary filter box 130, and the tertiary filter box 140... The filter box 130 and the top of the water storage unit 140 are interconnected through an overflow trough. When using the circulating filtration structure involved in this solution to filter water, the water to be filtered is injected into the primary filter box 110, and the first filtration is completed through the primary filter box 110. Since the primary filter box 110 is provided with a first through hole, the water filtered by the primary filter box 110 can be transferred to the secondary filter box 120 for secondary filtration through the first through hole. The bottom of the secondary filter box is connected to the third through hole at the bottom of the tertiary filter box through a second through hole, so that the water can be transferred from the bottom to the tertiary filter box 130. The top of the water storage unit 140 and the tertiary filter box 130 are provided with overflow troughs, so that the water can be transferred from the tertiary filter box 130 to the water storage unit 140, thus completing the filtration of the water. This solution can effectively ensure the filtration effect by setting up a multi-stage filtration structure, distinguishing it from existing conventional back filter, bottom filter, top filter, side filter and other structures.

[0039] In some embodiments, the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0040] Specifically, the first horizontal direction is set perpendicular to the second horizontal direction, which can reduce the size of the circulating filter structure in a single direction and avoid the problem of excessive length caused by a single direction.

[0041] In some embodiments, there are two filtration units, wherein the two filtration units are respectively disposed on both sides of the water storage unit 140.

[0042] Specifically, the design of two filtration units enables simultaneous filtration on both sides of the water storage unit 140, ensuring filtration efficiency.

[0043] In some embodiments, the filter unit further includes a connecting channel 121, wherein the second through hole and the third through hole are both connected to the connecting channel 121.

[0044] In some embodiments, the connecting channel 121 is disposed relative to the bottom of the secondary filter box 120 and the tertiary filter box 130.

[0045] Specifically, the connection between the secondary filter box 120 and the tertiary filter box 130 is achieved through the connecting channel 121, which ensures that the water level of the secondary filter box 120 and the tertiary filter box 130 remains consistent during the operation of the filtration system.

[0046] In some embodiments, the top of the three-stage filter box 130 is an open space, and heating and sterilization devices, temperature regulation devices, water replenishment devices, seawater filtration equipment, etc. can be placed in the three-stage filter box 130 according to different aquaculture needs, thereby realizing the functional diversity of the equipment.

[0047] like Figure 1 , Figure 4 As shown, this utility model embodiment also provides a fish tank, including the above-mentioned circulating filtration structure, and further including a tank body 200 with an inner cavity, the inner cavity of the tank body 200 being connected to the first filter box through a return water pipe 210; it also includes a water supply structure, the water supply structure being used to transfer the filtered water from the water storage unit 140 to the inner cavity of the tank body 200.

[0048] In some embodiments, the side of the cylinder 200 is provided with a receiving space 220 for accommodating the circulating filter structure.

[0049] In some embodiments, the accommodating space 220 has a U-shaped cross-section along the depth direction of the cylinder 200.

[0050] In some embodiments, the bottom of the cylinder 200 is provided with a water return structure, the water return structure includes a bearing surface 231, the bearing surface 231 is an inclined structure, and the bottom of the inclined structure is connected to the water return pipe 210.

[0051] In some embodiments, the water return structure further includes a filter screen 232, which is provided with small holes for fish feces to pass through; the filter screen 232 is disposed near the top of the cylinder 200 relative to the bearing surface 231.

[0052] The bottom of the inclined structure is connected to the return water pipe 210. Specifically, the inlet of the return water pipe 210 is located at the bottom of the inclined surface. Impurities in the water flow can be collected at the bottom of the inclined surface under the continuous flushing action of the water pump 241 driving the water flow circulation, and enter the circulation filtration system through the left and right side channels at the bottom of the inclined surface.

[0053] Specifically, by setting up a accommodating space 220 on the side, the circulating filter structure can be integrated into the entire structure during the manufacturing process through injection molding. The inner side of the U-shaped structure serves as the side of the tank body 200, with the glass 202 bonded to the front. This reduces the bonding process during manufacturing, lowering the risk of delamination, tank breakage, and leakage. It also achieves the desired aesthetic appeal. Compared to traditional aquariums that rely heavily on splicing and bonding, resulting in numerous pipe connections and a significant impact on the aquarium's appearance, this structural design allows for a one-piece injection molding of the U-shaped three-sided ring filter structure shell. This completely conceals the pipes and equipment required for aquarium aquarium maintenance, requiring only a single concealed water inlet on the inner wall of the aquarium.

[0054] Specifically, as those skilled in the art should know, the shell is formed by integral injection molding, and the shell serves as the side wall of the cylinder 200. The corresponding U-shaped space of the shell is used to store the circulating filter structure, such as... Figure 3 As shown, the height of the shell determines the water storage height of the cylinder 200. In order to prevent the water level in the cylinder 200 from being too high, a height limiting hole 201 is provided to communicate with the internal space of the shell, so that water above this position can enter the circulating filtration structure.

[0055] Furthermore, the height limiting orifice 201 is adapted to the position of the primary filter box 110, allowing water to flow directly into the primary filter box 110. The height limiting orifice 201 enables the filtration of surface water.

[0056] Specifically, the water supply structure is used to transfer the filtered water from the water storage unit 140 to the inner cavity of the cylinder 200. The water supply structure includes a pipe and a submersible water pump 241. The submersible water pump 241 is submerged at the bottom of the fourth-stage filter box. The water outlet 242 of the pipe is located below the water surface of the cylinder 200. That is, the water outlet 242 of the pipe is set close to the bottom of the cylinder 200 relative to the height limiting hole, which can further reduce water flow noise. Moreover, the use of a submersible water pump 241 can, to a certain extent, mask the operating noise of the water pump 241 motor through water flow.

[0057] It should be noted that, through the structural design of the water pump 241, water from the storage unit 140 can be pumped into the inner cavity of the tank 200, creating a certain negative pressure difference between the inner cavity of the tank 200 and the circulating filter structure. This pressure difference causes the water in the inner cavity of the tank 200 to continuously pass through the bottom filter screen 232, and then enter the return water pipe 210 through the left and right channels at the bottom of the slope. Since the height of the return water pipe 210 is lower than the highest water level of the tank 200, water will flow out from the return water pipe 210 and flow directly into the primary filter box 110. This achieves the goal of using the water circulation to draw the fish waste and other impurities settled in the aquarium into the primary filter box 110.

[0058] In some embodiments, the fish tank is further provided with a lighting structure and a control structure, the control structure being integrated into the top plate, which is aesthetically pleasing.

[0059] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are merely specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
