Description

Technical Field

[0001] This invention relates to the field of aquarium filtration technology, and in particular to a built-in aquarium filter structure. Background Technology

[0002] Currently, when keeping aquatic plants and animals, people are often troubled by the pollution of the aquarium water due to fish metabolic waste, uneaten fish food, and decaying aquatic plant leaves. This is because some aquatic plants and animals have very high requirements for water quality. If the water is polluted, it will affect their growth and even cause death. To deal with the above situation, people often use filters to draw water mixed with debris from the aquarium into the device, and the water is discharged from the outlet after filtration. Traditional aquarium filter modules usually adopt an external design, which requires the installation of pipes outside the aquarium to connect the various filter components. This design not only takes up extra space, but also affects the overall aesthetics of the aquarium.

[0003] Later, built-in aquarium filters appeared on the market. These filters are placed inside the aquarium. When in use, wastewater from the aquarium enters the filter directly through the inlet and flows directly through or impacts the filter media. The filtered water is then pumped back into the aquarium by a drain pump. However, their structural design is flawed. Because the inlet of the built-in aquarium filter is directly exposed to the aquarium water and only performs the initial interception of solid impurities, it is prone to accumulating fish feces, uneaten food, and other dirt. When users need to maintain or clean the filter and remove it from the aquarium, the dirt accumulated near the inlet and the dirt attached to the filter media can easily be re-spread into the aquarium water due to movement, shaking, or water flow disturbance when the filter is removed, causing secondary pollution of the water. This affects water quality, requiring users to filter the secondary polluted aquarium water again, which is time-consuming, laborious, and has a limited range of applications.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a built-in aquarium filter structure. Through the design of the sludge collection tank, the solid dirt in the wastewater is intercepted and deposited in the sludge collection tank, preventing the dirt from scattering due to the movement of the product when the user removes it later. This avoids secondary pollution of the aquarium water, thereby ensuring the water quality in the aquarium. It is time-saving, labor-saving, and has a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated aquarium filter structure includes a housing, a filter module mounted on the housing, and a drain pump; wherein: The housing contains a filter chamber and a sludge collection tank. The sludge collection tank is located on one side of the filter chamber. One end of the sludge collection tank passes through the housing and has a water inlet. The other end of the sludge collection tank is connected to the filter chamber. The filter module is located inside the filter chamber. The drain pump is located beside the filter chamber and is connected to the filter chamber.

[0007] As a preferred embodiment, the filter chamber has a positioning edge extending toward the filter module. The positioning edge is provided in at least two sets and disposed on the inner wall surface of the filter chamber. The inner end of the positioning edge is in contact with and positioned against the outer wall of the filter module.

[0008] As a preferred embodiment, the sludge collection tank is arranged in a gradually increasing manner from the water inlet toward the filter chamber.

[0009] As a preferred embodiment, the upper end of the housing is detachably connected to a top cover.

[0010] As a preferred embodiment, a positioning structure is provided between the top cover and the housing. The positioning structure includes a positioning part and a positioning groove. One of the positioning part and the positioning groove is provided on the top cover, and the other is provided on the housing. The positioning part and the positioning groove are adapted to realize the assembly connection between the top cover and the housing.

[0011] As a preferred embodiment, a lateral water inlet is provided on the outer side of the housing, and the water inlet is located at the lower end of the housing, with the lateral water inlet connected to the water inlet.

[0012] As a preferred embodiment, the sludge collection trough extends vertically, is located on the left side of the filter chamber, and its upper end is connected to the filter chamber. The drain pump is located on the right side of the filter chamber.

[0013] As a preferred embodiment, the housing is further provided with an installation cavity, which is located on the right side of the filter chamber. The drain pump is mounted on the installation cavity. The left end of the installation cavity is connected to the filter chamber through a central through hole. The right end of the filter module abuts against the central through hole to form a circumferential seal between the two.

[0014] As a preferred embodiment, the sludge collection tank has an inverted U-shaped structure, the water inlet is located on the lower side of one end of the sludge collection tank, the sludge collection tank is located on the front side of the filter chamber, the lower side of the other end of the sludge collection tank is connected to the filter chamber, and the drain pump is located on the upper side of the filter chamber.

[0015] As a preferred embodiment, the filter chamber is provided with support protrusions, and at least two support protrusions are arranged in parallel. The lower end of the filter module is supported and connected to the upper end of the support protrusions, and the two support protrusions are located on the side of the other end of the sludge collection tank.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: The design of the waste collection tank allows the wastewater from the aquarium to first enter the waste collection tank and then flow into the filter chamber from the other end of the waste collection tank. This traps and deposits some of the solid dirt in the wastewater, preventing the dirt from scattering when the product is removed later. This avoids secondary pollution of the aquarium water and ensures the water quality in the aquarium. It saves time and effort, meets the user's needs, and has a wide range of applications. Secondly, the positioning edge facilitates the assembly and positioning of the filter module in the filter chamber, preventing displacement of the filter module during product use. This ensures that the filter module is always positioned in the preset position, thereby guaranteeing the stability and usability of the filter module. Furthermore, the detachable design of the top cover facilitates subsequent disassembly and cleaning operations for users. Combined with the positioning structure, it ensures precise positioning between the top cover and the shell, thereby ensuring a good seal between the top cover and the shell. Furthermore, the side inlet holes facilitate the entry of large particles of dirt into the sludge collection tank, preventing blockage of the inlet due to large particles of dirt. This ensures the entry of wastewater and the deposition of dirt on the sludge collection tank, improving the reliability and usability of the product.

The left end of the installation cavity 17 is connected to the filter chamber 11 through a central through hole 171. The right end of the filter module 20 abuts against the central through hole 171 to form a circumferential seal, so that after the sewage enters the filter chamber, it is effectively filtered by the filter module and then enters the installation cavity through the central through hole, and is finally discharged by the drain pump.

[0026] Specifically, the housing 10 has a recessed cavity 101 with an opening at the upper end. The upper cover 15 is disposed at the upper end of the housing 10 to close the recessed cavity 101. The rear end of the upper cover 15 is rotatably connected to the rear side of the upper end of the housing 10. The front end of the upper cover 15 is provided with a fastening member 153 for snap-fit ​​connection with the housing.

[0029] The key design feature of this invention is that, through the design of the sludge collection tank, the wastewater from the aquarium first enters the sludge collection tank and then flows into the filter chamber from the other end of the sludge collection tank. This allows some solid dirt in the wastewater to be intercepted and deposited in the sludge collection tank, preventing dirt from scattering due to the movement of the product when the user removes it later. This avoids secondary pollution of the aquarium water, thus ensuring the water quality in the aquarium. It saves time and effort, meets the user's needs, and has a wide range of applications.
