Description

Technical Field

[0001] This utility model relates to the field of aquarium technology, and in particular to a fish tank with an easily detachable water pump. Background Technology

[0002] In the aquarium industry, sump-filter aquariums are widely popular due to their high-efficiency filtration performance and aesthetically pleasing design. Sump-filter aquariums typically place the filter assembly at the bottom of the tank, using a water pump to circulate the water, allowing it to flow through the filter structure to remove impurities and degrade harmful substances, thus maintaining clean and stable water quality. At the same time, the sump-filter design makes full use of the space at the bottom of the aquarium, avoiding the filter structure taking up too much side space and affecting the overall aesthetics and harmony of the aquarium.

[0003] For bottom-filter aquariums, the water pump is typically integrated into the filtration system at the bottom of the tank. While this layout simplifies initial installation and reduces external piping, it significantly complicates later maintenance. As a core component of the water circulation system, the water pump is prone to performance degradation due to clogged filtration systems and mechanical malfunctions over time, necessitating disassembly and maintenance. For example, the pump may become clogged with fish waste, algae, or other debris, affecting its normal operation; it may also require replacement or repair due to damaged fan blades or motor failure. However, in typical bottom-filter aquariums, this means removing the entire filtration system to access the pump, undoubtedly increasing the difficulty of maintenance for the user. Utility Model Content

[0004] Therefore, it is necessary to provide a fish tank with an easily detachable water pump, so that users can easily remove the water pump located in the water body of the fish tank.

[0005] This utility model provides an aquarium with an easily detachable water pump, including a tank body, a bottom filter component, a water supply component, and a water pump; the tank body has an inner cavity for accommodating water; the bottom filter component is located at the bottom of the inner cavity, and has a bottom water inlet and an installation port connected to each other; the water supply component is located in the inner cavity, with its upper end extending to the top of the tank body and its lower end detachably installed in the installation port; the water pump is installed in the water supply component and located in the installation port, and the water pump is connected to both the bottom water inlet and the water supply component.

[0006] Compared to existing technologies, the aquarium provided in this application embodiment has a water pump located in the mounting port of the bottom filter component, i.e., below the water body. This allows the water pump to operate directly at its normal working height without running dry. At the same time, the water pump is fixedly installed on the water supply component, and the top of the water supply component extends to the top of the aquarium, i.e., above the water body. The lower end of the water supply component is detachably connected to the mounting port. Therefore, users can lift the water pump from the top of the water supply component to clean and repair it, greatly reducing the difficulty of maintenance.

[0007] In one embodiment, the bottom filter component further includes a bottom filter plate, a bottom panel, and a mounting portion. The bottom panel is located at the bottom of the inner cavity, and the bottom filter plate covers the bottom panel. The mounting portion is connected to the bottom filter plate or the bottom panel. The bottom inlet is formed on the bottom filter plate, and the mounting port is formed on the mounting portion. A first flow channel connecting the bottom inlet and the mounting port is formed between the bottom panel and the bottom filter plate. The bottom filter plate effectively isolates impurities such as sand and aquatic plants from the bottom of the water body and the water pump, preventing sand and gravel from clogging the water pump's water passages. In addition, the bottom filter plate and the bottom panel constitute a concealed filtration space, which does not occupy the side space of the tank and ensures the aesthetics of the aquarium.

[0008] In one embodiment, the height of the mounting portion is higher than that of the bottom filter plate, and the mounting opening is formed at the top of the mounting portion. The bottom filter plate is typically decorated with sand, aquatic plants, and other decorative elements, and also accumulates fish feces and other impurities. By making the height of the mounting opening of the mounting portion higher than that of the bottom filter plate, it is possible to effectively prevent sand and other impurities from covering the connection between the water supply component and the mounting opening. Therefore, when the water supply component is removed from the mounting portion, these impurities are less likely to flow into the mounting opening and enter the already pre-filtered first flow channel.

[0009] In one embodiment, the bottom filter plate is provided with sand and gravel, and the height of the mounting part is higher than the sand and gravel. The particle size of the sand and gravel is often significantly larger than impurities such as fish feces, and can easily cause substantial damage to the pump blades. By controlling the height relationship between the mounting part and the sand and gravel, the surrounding sand and gravel can be avoided, effectively preventing sand and gravel from easily entering the mounting opening and damaging the reinstalled pump after the water supply component is removed from the mounting part.

[0010] In one embodiment, the water supply assembly includes a water supply pipe and a mounting base plate. The mounting base plate is fixed to the bottom of the water supply pipe, and the water pump is fixed to the mounting base plate. The mounting base plate is detachably installed over the mounting opening. A water supply channel is formed in the water supply pipe. The inlet of the water pump is connected to the bottom inlet, and the outlet of the water pump is connected to the water supply channel. The mounting base plate, as a key connector, simultaneously performs three functions: fixing the water supply pipe, supporting the water pump, and sealing the mounting opening. This integrated design makes the connection between the water pump and the water supply channel more compact and direct, reducing unnecessary connecting pipes and lowering water flow resistance and leakage risk. Furthermore, this design simplifies the disassembly and assembly of the water pump to the operation of the mounting base plate.

[0011] In one embodiment, the bottom of the mounting base plate is provided with a snap-fit ​​component that secures the water pump. This snap-fit ​​structure makes it easier to assemble and disassemble the water pump on the mounting base plate, enabling rapid installation and fixation of the water pump. Simultaneously, it enhances the stability of the connection between the water pump and the mounting base plate, ensuring the seal between the water pump's outlet and the water inlet channel.

[0012] In one embodiment, the mounting base plate is inserted into the mounting port along its height and transition-fits with the mounting port, or the mounting base plate is threadedly connected to the mounting port. The transition-fit method allows for smooth insertion and removal between the mounting base plate and the mounting part, making assembly and disassembly very convenient. The threaded connection method provides higher connection strength and stability between the mounting base plate and the mounting part, preventing loosening due to accidental impact.

[0013] In one embodiment, the water supply pipe has an outlet on its side wall, which is connected to the water supply channel; and a drain outlet is provided at the top of the water supply pipe, which is also connected to the water supply channel. The presence of an outlet on the side and a drain outlet at the top of the water supply pipe helps to integrate the pipeline structure, greatly reducing the complexity of the pipeline.

[0014] In one embodiment, the water supply pipe has a columnar structure and is detachably installed on the top of the cylinder. This design simplifies the shape of the water supply pipe, and the top of the water supply pipe can also connect to the cylinder, improving the stability of the water supply pipe and preventing swaying when water flows through it, which would affect the stability of the water supply assembly and the mounting part.

[0015] In one embodiment, the aquarium further includes a top cover, which is disposed on the top of the aquarium body, and the top end of the water supply pipe passes through the top cover. The water supply assembly also includes a hook fastener, which is fixed to the water supply pipe and hung on the top of the aquarium body, with the top cover pressing against the hook fastener. The water supply assembly can be easily attached to the aquarium body via the hook fastener, achieving convenient assembly and disassembly. At the same time, the top cover presses down on the hook fastener. This design distributes the water flow collisions and vibrations from the water pump operation in the water supply assembly to the entire aquarium frame through the top cover, rather than relying solely on the mounting part at the bottom. This greatly enhances the stability of the entire water supply assembly in the height direction, preventing it from swaying or tilting. Attached Figure Description

[0024] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0028] For bottom-filter aquariums, the water pump is often integrated into the filtration structure at the bottom of the water body. While this layout simplifies initial installation and reduces external piping, it significantly complicates later maintenance. As a core component of the water circulation system, the water pump is prone to performance degradation and malfunction due to accumulated impurities, blockages, and mechanical failures over time, requiring removal for maintenance. However, in typical bottom-filter aquariums, this means removing the entire filtration structure at the bottom of the water body to access the pump, undoubtedly increasing the difficulty of maintenance for the user. Therefore, this application provides an aquarium with a design that allows users to easily remove the water pump located within the water body.

[0029] refer to Figure 1 , Figure 2 and Figure 3 In the embodiments provided in this application, the fish tank includes a tank body 10, a bottom filter component 20, a water supply assembly 30, and a water pump 40. The tank body 10 may be composed of multi-faceted plastic or glass side panels 11 and a base 12. The side panels 11 and the base 12 form an inner cavity 101 for containing water. The inner cavity 101 can generally have common structural shapes such as cubes or cylinders. The fish tank in the embodiments of this application can be a desktop fish tank.

[0030] The bottom filter component 20 is located at the bottom of the inner cavity 101. The bottom filter component 20 is used for preliminary filtration of water. The bottom filter component 20 is provided with a bottom inlet 211 and an installation port 231 that are connected to each other. A first flow channel 221 is also formed between the bottom inlet 211 and the installation port 231 (see reference). Figure 4 The bottom inlet 211 is located below the water body and circulates water in conjunction with the water supply component 30 through bottom suction. The bottom filter design minimizes the obstruction of the filter structure's view of the sides of the tank 10, enhancing the aquarium's aesthetic appeal. Larger-diameter gravel can be laid above the bottom inlet 211 to cover it and achieve initial filtration.

[0031] The water supply component 30 is located in the inner cavity 101, and its upper end extends to the top of the cylinder 10, which may be slightly lower or higher than the top of the cylinder 10. When the cylinder 10 is filled with a certain amount of water, the upper end of the water supply component 30 will be above the water surface, making it easy for the user to remove without having to put their hands into the water. The lower end of the water supply component 30 is detachably installed in the mounting port 231. In the embodiments of this application, the detachable relationship between the lower end of the water supply component 30 and the mounting port 231 can be such that the user can easily separate the water supply component 30 from the mounting port 231 by applying force to the upper end of the water supply component 30. The application method is, for example, pulling up or rotating the water supply component 30 in the height direction. The corresponding connection method can be a transition fit or a threaded connection between the lower end of the water supply component 30 and the mounting port 231.

[0032] Furthermore, the water pump 40 is installed on the water supply assembly 30 and located below the water supply assembly 30. After the water supply assembly 30 is installed with the mounting port 231, the mounting port 231 is blocked by the water supply assembly 30, so that water cannot flow through the installation gap between the water supply assembly 30 and the mounting port 231 to reach the water pump 40. The water pump 40 extends into and is located in the mounting port 231, and the water pump 40 is connected to both the bottom water inlet 211 and the water supply assembly 30.

[0033] Driven by the water pump 40, the water in the inner cavity 101 enters the bottom filter component 20 from the bottom inlet 211, flows through the first flow channel 221 in the bottom filter component 20 to the water pump 40 located at the installation port 231, and is then pumped by the water pump 40 to the water supply component 30, and finally flows back to the water in the inner cavity 101 through the water supply component 30, thereby realizing water circulation.

[0034] Compared to existing technologies, in the fish tank provided in this application embodiment, the water pump 40 is located in the mounting port 231 of the bottom filter component 20, that is, below the water body. In this way, the water pump 40 can work directly at its normal operating height without running dry. At the same time, the water pump 40 is fixedly installed on the water supply component 30, and the top of the water supply component 30 extends to the top of the tank body 10, that is, above the water body. The lower end of the water supply component 30 is detachably connected to the mounting port 231. Therefore, the user can lift the water pump 40 through the upper end of the water supply component 30, thereby cleaning and repairing the water pump 40, which greatly reduces the difficulty of maintenance.

[0035] In some embodiments, the bottom filter component 20 further includes a bottom filter plate 21, a bottom panel 22, and a mounting portion 23. The bottom panel 22 is disposed at the bottom of the inner cavity 101, the bottom filter plate 21 is disposed on the bottom panel 22, the mounting portion 23 is connected to the bottom filter plate 21 or the bottom panel 22, the bottom inlet 211 is formed on the bottom filter plate 21, the mounting port 231 is formed on the mounting portion 23, and a first flow channel 221 is formed between the bottom panel 22 and the bottom filter plate 21, connecting the bottom inlet 211 and the mounting port 231. Above the bottom filter plate 21, there is sand and gravel for coarse filtration. The sand and gravel cover the bottom water inlet 211. The bottom filter plate 21 effectively isolates impurities such as sand and gravel and aquatic plants from the bottom of the water body and the water pump 40, preventing the sand and gravel from clogging the water passage of the water pump 40. In addition, the bottom filter plate 21 and the bottom panel 22 are located under the sand and gravel and other landscaping, forming a hidden filtration space that does not occupy the side space of the tank body 10, thus ensuring the aesthetics of the aquarium.

[0036] To prevent sand and other impurities on the bottom filter plate 21 from flowing into the mounting port 231 after the water supply assembly 30 is separated from the mounting part 23, the height of the mounting part 23 can be higher than the bottom filter plate 21, and the mounting port 231 is located at the top of the mounting part 23. Furthermore, for aquariums with pre-laid sand and gravel, the height of the mounting part 23 should be higher than the sand and gravel. The bottom filter plate 21 is usually decorated with sand, aquatic plants, etc., and will also accumulate some fish waste and other impurities. By making the mounting port 231 of the mounting part 23 higher than the bottom filter plate 21, it is possible to effectively prevent sand and other impurities from covering the connection between the water supply assembly 30 and the mounting port 231. Therefore, when the water supply assembly 30 is removed from the mounting part 23, these impurities are less likely to flow into the mounting port 231 and enter the already pre-filtered first flow channel 221. In particular, for sand and gravel, the particle size of sand and gravel is often significantly larger than impurities such as fish feces, and it can easily cause substantial damage to the blades of the water pump 40. This embodiment can avoid the surrounding sand and gravel by controlling the height relationship between the mounting part 23 and the sand and gravel.

[0037] In one embodiment, the bottom panel 22 is fixed above the aquarium base 12, or it is part of the aquarium base 12 itself. The top side of the bottom panel 22 is flat or has a groove, and the bottom filter plate 21 is placed on the bottom panel 22 to form a first flow channel 221 with the flat surface or groove. The bottom inlet 211 on the bottom filter plate 21 may be composed of a large number of fine holes, the diameter of which is smaller than the particle size of the sand, to prevent sand from passing through into the first flow channel 221. The mounting part 23 may be formed on the bottom filter plate 21, for example, integrally formed with the bottom filter plate 21 for easy removal as a whole; or the mounting part 23 may also be formed on the bottom panel 22, with the first flow channel 221 extending to the first mounting opening 231 of the mounting part 23.

[0038] The water supply assembly 30 receives the water pumped upwards by the water pump 40 and guides the water back into the water body in the inner cavity 101 to achieve circulation. Specifically, the water supply assembly 30 includes a water supply pipe 31 and a mounting base plate 32. The mounting base plate 32 is fixed to the bottom of the water supply pipe 31, and the two can be integrally formed, snap-fitted, or connected by fasteners. The water pump 40 is fixed to the mounting base plate 32, which is detachably covered by the mounting port 231. A water supply channel is formed in the water supply pipe 31. The water inlet of the water pump 40 is located in the space formed by the mounting port 231 and the first channel 221 to connect with the bottom water inlet 211. The water outlet 302 of the water pump 40 abuts against the mounting base plate 32 or the water supply pipe 31 to connect with the water supply channel. A sealing ring can be provided between the water outlet 302 of the water pump 40 and the water supply channel to achieve a seal at the transition. The water supply pipe 31 can be in the form of a columnar structure, such as a cylindrical structure. In some embodiments, the water supply pipe 31 is detachably installed on the top of the cylinder body 10. Specifically, the water supply assembly 30 also includes a hook fastener, which is fixed to the water supply pipe 31 and hung on the top of the cylinder body 10. The hook fastener has a hook structure, which is sleeved on the water supply pipe 31 and hooked on the top of the cylinder body 10 through the hook structure.

[0039] refer to Figure 3 and Figure 4 In one embodiment of water circulation, the side wall of the water inlet pipe 31 has an outlet 302, which is connected to the water inlet channel. The outlet 302 is located near the top of the water inlet pipe 31, and its height is generally above the water surface. The water flowing into the water inlet channel from the water pump 40 can return to the water in the inner cavity 101 through the outlet 302, thereby achieving circulation. In addition, the top of the water inlet pipe 31 has a drain outlet 303, which is connected to the water inlet channel. The drain outlet 303 can be connected to a flexible hose, so that the water can be gradually discharged from the fish tank under the action of the water pump 40. When not draining, the top of the water inlet pipe 31 can be sealed with a cap 34, so that all the water in the water inlet channel can be discharged from the outlet 302. By opening the outlet 302 on the side of the water inlet pipe 31 and the drain outlet 303 at the top, it is helpful to integrate the pipeline structure and greatly reduce the complexity of the pipeline.

[0040] refer to Figure 5 To improve the ease of assembly and stability between the mounting base plate 32 and the mounting port 231, a stepped structure 321 can be formed on the outer edge of the mounting base plate 32. The edge of the mounting port 231 is adapted to and can be inserted into the stepped structure 321. As a key connector, the mounting base plate 32 simultaneously performs three functions: fixing the water supply pipe 31, supporting the water pump 40, and sealing the mounting port 231. This integrated design makes the connection between the water pump 40 and the water supply channel more compact and direct, reducing unnecessary transfer pipes and lowering water flow resistance and leakage risk.

[0041] After the water pump 40 is installed on the water supply assembly 30, the two can be installed and removed simultaneously as a single structure at the mounting port 231. Due to turbulent water flow or collisions with fish, the water supply assembly 30 may become loose relative to the mounting port 231. To solve this problem, in the embodiments of this application, the mounting base plate 32 can be inserted into the mounting port 231 along the height direction and transitionally fitted with the mounting port 231. For example, the structural dimensions of the mounting base plate 32 inserted into the mounting port 231 can be the same as or slightly larger than the diameter of the mounting port 231, so that the two can provide damping through the structural elastic deformation during installation; or the mounting base plate 32 can be threadedly connected to the mounting port 231, with threads at the joint. The user can control the tightening or loosening by rotating the top of the water supply assembly 30 to rotate the mounting base plate 32 synchronously relative to the mounting port 231, thereby achieving installation and removal. The transitional fit method can achieve smooth insertion and removal operations between the mounting base plate 32 and the mounting part 23, making installation and removal very convenient. The threaded connection provides higher connection strength and stability between the mounting base plate 32 and the mounting part 23, preventing the water supply component 30 from falling off the mounting port 231 due to accidental collision or strong current impact.

[0042] refer to Figure 5 The installation method between the water pump 40 and the mounting base plate 32 can be varied, but it is required that the water pump 40 remain stable relative to the mounting base plate 32 and the water inlet pipe 31. Therefore, in some embodiments, at least two snap-fit ​​pieces 322 can be provided extending downwards from the bottom of the mounting base plate 32. These snap-fit ​​pieces 322 secure the water pump 40 to the mounting base plate 32, ensuring the seal between the water outlet 302 of the water pump 40 and the water inlet channel. This structure also facilitates quick installation and removal of the water pump 40 from the mounting base plate 32. Besides the snap-fit ​​connection method, the mounting base plate 32 and the water pump 40 can also be fixed together using common assembly methods such as fasteners.

[0043] In some embodiments, the aquarium further includes a top cover 50, which covers the top of the tank body 10, and the top end of the water supply pipe 31 passes through the top cover 50. In some embodiments with hooks, the top cover 50 can be pressed onto the hooks simultaneously, increasing the stability of the water supply pipe 31. In other embodiments, the top end of the water supply pipe 31 can also be clipped onto the top cover 50. The top cover 50 supports the top end of the water supply pipe 31, dispersing the water flow collisions in the water supply assembly 30 and the vibrations from the operation of the water pump 40 to the entire aquarium frame, rather than being borne solely by the bottom mounting portion 23. This greatly enhances the stability of the entire water supply assembly 30 in the height direction, preventing it from swaying or tilting.

[0044] As described above, the fish tank provided in this application embodiment allows users to easily remove the water pump 40 from the top of the water supply component 30, enabling easy disassembly and assembly of the water pump 40 for cleaning and maintenance, thus greatly reducing maintenance difficulty.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
