Description

Technical Field

[0001] This utility model relates to the field of ecological aquarium technology, and specifically to a filtration structure. It also discloses an ecological aquarium equipped with a filtration structure. Background Technology

[0002] An ecological aquarium is an indoor device used for raising ornamental fish. To keep the water in the aquarium clean and hygienic, a filtration system is installed in the circulating water system to filter and disinfect the water. The filtration system uses various filter media to filter the water, preventing impurities such as fish food and decaying matter from flowing back into the aquarium through the circulating water system.

[0003] For example, Chinese patent CN216219594U discloses a six-stage circulating filtration system for aquariums, including: a tank body, a filtration device assembled in the tank body, and a top cover assembled at the top opening of the tank body; the filtration device includes: a filter box, six sets of filter elements assembled in the filter box, and a water pump; the filter box has an installation cavity for inserting and assembling the filter elements, and the filter elements are detachably installed in the filter box by snap-fit; the water pump operates to make the water in the filter box flow through the six sets of filter elements in sequence and then flow back into the tank body, so that the impurities and pollutants in the water are filtered by the six sets of filter elements in sequence, resulting in a high water purification effect.

[0004] In the aforementioned prior art, six filter cartridges are installed in the filter box via clips, which proportionally increases the amount of disassembly required when cleaning or replacing the filter cartridges. After the filter cartridges are removed, contaminants in the water remain inside the filter box and cannot be removed. Over time, debris will enter the water pump, reducing its circulation efficiency and affecting its lifespan.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a filter structure that is reasonably designed, requires low maintenance, and is easy to clean, as well as an ecological fish tank equipped with a filter structure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model discloses a filter structure comprising a housing, a water pump module, and a filter module. The housing contains a water inlet chamber, a filter chamber, and a water extraction chamber connected in sequence. The housing has a hook, and its side wall has a water inlet and a water outlet, with the water inlet connecting to the water inlet chamber. The filter module is detachably mounted within the filter chamber, and the water pump module is detachably mounted within the water extraction chamber, connected to the water outlet. This utility model features a detachable design; specifically, both the water pump module and the filter module are detachably mounted within the housing. The housing of the filter structure can also be removed from the water tank, facilitating the cleaning of residual dirt in the water inlet chamber, filter chamber, and water extraction chamber. It is understood that the filter module is also detachable, facilitating the replacement or cleaning of the filter media.

[0009] According to the above scheme, the upper end of the shell is open, and several vertical partitions are provided inside the shell. These vertical partitions are arranged at intervals to form a water inlet chamber, a filter chamber, a water pumping chamber, and several channels within the shell. The water inlet chamber, filter chamber, and water pumping chamber are connected sequentially through the channels. It can be understood that the shell consists of a front sidewall, a rear sidewall, and two side walls surrounding a bottom plate, forming a rectangular hollow structure with an open upper end. Several vertical partitions are arranged at intervals along the horizontal direction within the shell's interior. The vertical partitions connect the front and rear sidewalls of the shell, thus forming the water inlet chamber, filter chamber, water pumping chamber, and several channels within the shell. Of course, except for the water pumping chamber formed by the vertical partitions adjacent to the side walls of the shell, the other water inlet chambers, filter chambers, and channels are formed by two adjacent vertical partitions on the left and right sides. The vertical partitions divide the shell's interior into a drawer-type structure, facilitating the insertion and maintenance of the filter module and the water pumping module.

[0010] In particular, the two adjacent vertical partitions forming the channel can be staggered vertically to control the flow path of water in the inlet chamber, filter chamber, pumping chamber and channel, so as to meet the layout requirements of the pump module and filter module.

[0011] According to the above scheme, the filtration module includes a housing and filter media. The housing has several compartments arranged vertically, each containing filter media. It is understood that the sequential arrangement of the compartments allows water to pass sequentially through the filter media within each compartment, thus achieving filtration. Of course, the filter media can be arranged sequentially within the compartments according to filtration density. Preferably, the filter media includes physical filter cotton and biological filter cotton. Each compartment can contain at least one physical filter cotton and multiple biological filter cottons. The water first passes through the physical filter cotton, which filters out impurities such as fish food and decaying aquatic plants. Then, it passes through the biological filter cottons sequentially, improving the filtration effect. Furthermore, the various biological filter cottons can cultivate various beneficial bacteria, thereby improving water quality and ensuring the survival of fish.

[0012] According to the above scheme, the box body is inserted between two vertical partitions. Water inlet and outlet grids are respectively provided on the side walls of the box body. A dirt-collecting chamber is provided at the top of the box body, adjacent to the compartment for placing physical filter cotton. The dirt-collecting chamber is connected to a channel on one side through the water inlet grid, and the compartment for placing biochemical filter cotton at the bottom of the box body is connected to a channel on the other side through the water outlet grid. Similarly, the inner cavity of the shell is divided by multiple vertical partitions to form a filtration chamber and a water-drawing chamber. Typically, the filtration chamber and water-drawing chamber are rectangular, and correspondingly, the box body is also rectangular, facilitating the insertion and positioning of the filtration chamber. The water inlet and outlet grids constitute the water inlet and outlet connecting the inner cavity of the box body, allowing water to flow along the filter media in several compartments. Preferably, the inlet and outlet grids are located on the side walls of the housing. When the housing is inserted into the filter chamber, the side walls of the housing are positioned against the vertical partitions on both sides. Simultaneously, the upper and lower misalignments of these two vertical partitions expose the inlet and outlet grids to connect the corresponding channels, thus simplifying the structure and facilitating installation. It is understood that after the housing is inserted into the filter chamber, it forms a seal against the front and rear side walls of the housing and the two vertical partitions, allowing water to flow sequentially from the inlet grid, the various compartments within the housing, and the outlet grid.

[0013] According to the above solution, the housing also includes a cover, with an opening on the front side. The cover is detachably sealed to the opening. The filter module can be removed from the filter chamber, and the filter media inside can be replaced after opening the cover. The filter media includes physical filter cotton and biological filter cotton, both of which can be washed and reused to extend their service life.

[0014] According to the above scheme, the water pump module includes a pump casing and a pump body. An adapter is provided at the upper end of the pump casing, and the pump casing is inserted into the water pumping chamber to mate the adapter with the drain outlet. The pump body is fixedly installed in the middle of the pump casing, and a water pipe connecting to the adapter is provided on the pump body. A water-passing mesh is provided on the side wall at the lower end of the pump casing, and water pump filter cotton is provided at the lower part of the pump casing. The pump body is a submersible pump, and the working principle of the water pump module is the same as that of existing technology, so it will not be described in detail here. Preferably, after water enters the pump casing through the water-passing mesh, it is filtered by the water pump filter cotton to remove only the remaining fine fish feces / debris, which can effectively improve the service life of the pump body. Preferably, the water pump module can also be disassembled from the water pumping chamber. Simultaneously, the pump casing is provided with a removable cover to clean and maintain the water pump filter cotton, clean the inner cavity of the pump casing and the water-passing mesh, and prevent a decrease in the pumping circulation efficiency of the pump body.

[0015] According to the above scheme, the water inlet chamber is located in the middle of the shell, and a filter chamber and a pumping chamber are provided on both sides of the water inlet chamber. The filter chamber and the pumping chamber are respectively equipped with a filter module and a water pump module. This utility model preferably uses two sets of filter modules and water pump modules, and through a dual-circulation water and filtration system, improves water treatment efficiency, ensures water quality, and increases the survival rate of ornamental fish.

[0016] According to the above scheme, this utility model also includes a heat preservation chamber. Heat preservation chambers are provided on both sides of the water inlet chamber. The water inlet chamber, heat preservation chamber, filter chamber, and pumping chamber are sequentially connected by a channel. A heater is provided inside the heat preservation chamber. The heater can heat the water and transport it to the tank via water circulation to ensure the required water temperature for the ornamental fish.

[0017] According to the above scheme, the side wall of the shell is provided with two water inlets, which are arranged vertically. The fish food contains oil, which floats on the surface of the water after contact with the food, affecting the appearance of the aquarium. Preferably, one of the water inlets is located at the upper part of the water inlet chamber, corresponding to the water level in the tank, so that the oil film on the water surface can be sucked into the water inlet chamber. The other water inlet is located at the lower part of the water inlet chamber, mainly used to remove fish feces, leftover fish food, and other debris from the water.

[0018] An ecological fish tank with a filtration structure includes a water tank. The housing is disposed inside the water tank and connected to the rim of the water tank via hooks. The water inlet chamber is connected to the inner cavity of the water tank through two water inlets, and the pump body is connected to the inner cavity of the water tank through an adapter and a drain outlet. The filtration structure of this invention adopts a detachable design, and the connection to the rim of the water tank via hooks on the housing makes disassembly and assembly very convenient. Both the water pump module and the filter module are detachably disposed within the housing, thereby facilitating the cleaning of residual dirt in the water inlet chamber, filter chamber, and pumping chamber.

[0019] This utility model discloses a filtration structure and an ecological fish tank. The water pump module and the filter module are detachably installed in the housing. The housing is connected to the water tank by hooks, making it detachable for cleaning the internal water inlet chamber, filter chamber, and water pumping chamber. This facilitates cleaning of the filter module, water pump module, and the inner cavity of the housing, effectively extending the service life of the water pump and improving the water quality in the fish tank.

The inlet chamber 21, filter chamber 22, and pumping chamber 23 are connected sequentially through the channels 27. It can be understood that the housing 2 is a rectangular hollow structure with an open upper end, formed by a front sidewall, a rear sidewall, and two sidewalls surrounding a bottom plate. Several vertical partitions 26 are spaced apart laterally within the inner cavity of the housing 2. The vertical partitions 26 connect the front and rear sidewalls of the housing 2, thereby forming the inlet chamber 21, filter chamber 22, pumping chamber 23, and several channels 27 within the housing 2. Of course, except for the pumping chamber 23 formed by the vertical partitions 26 adjacent to the sidewalls of the housing 2, the other inlet chambers 21, filter chambers 22, and channels 27 are all formed by two adjacent vertical partitions 26 spaced apart. The vertical partitions 26 divide the inner cavity of the housing 2 to form a drawer-type structure, thereby facilitating the insertion and maintenance of the filter module 4 and the pumping module.

Each compartment 43 can contain at least one physical filter cotton 421 and multiple biological filter cottons 422. Water first passes through the physical filter cotton 421, filtering out impurities such as fish food and decaying aquatic plants. Then, it passes through the biological filter cottons 422, improving the filtration effect. Furthermore, the various biological filter cottons 422 can cultivate beneficial bacteria, thereby improving water quality and ensuring the survival of fish.

When the housing 41 is inserted into the filter chamber 22, the two side walls of the housing 41 are positioned against the vertical partitions 26 on both sides. At the same time, the misalignment of these two vertical partitions 26 exposes the inlet grid 44 and outlet grid 45 to connect the corresponding side channels 27, thereby simplifying the structure and facilitating installation. It can be understood that after the housing 41 is inserted into the filter chamber 22, it forms a seal against the front and rear side walls of the housing 2 and the two vertical partitions 26, allowing water to flow sequentially from the inlet grid 44, the several compartments 43 within the housing 41, and the outlet grid 45.

[0033] The housing 41 also includes a cover 47, with an opening on the front side. The cover 47 is detachably sealed to the opening of the housing 41.
