Description

Technical Field

[0001] This utility model relates to the field of aquarium supplies, and in particular to a pre-filter for aquarium waste. Background Technology

[0002] Common aquarium physical filters on the market mainly rely on a water pump to power the water flow through filter media such as filter floss and bio-foam, using the filter media's interception effect to trap solid particles. However, feces and impurities directly adhere to the surface of the filter floss, quickly causing blockage and increasing water flow resistance. This not only reduces filtration efficiency but also increases the load on the water pump, and may even burn out the water pump due to obstructed water flow.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems. We provide a pre-filter for aquarium waste that can trap large particles in the water, effectively preventing the filter cotton from clogging.

[0005] To achieve the above objectives, this utility model provides a pre-filter for aquarium waste, comprising a housing, with an outlet and an inlet on the upper and lower sides of the housing, respectively. The housing contains a first water channel, a second water channel, a retention area, and a third water channel. The inlet is located at the lower end of the first water channel. The second water channel surrounds the outer side of the first water channel. The upper end of the first water channel has an outlet connecting to the second water channel. The lower end of the second water channel connects to the retention area. The third water channel surrounds the outer side of the second water channel and connects to the outlet. A ring-shaped filter screen is provided between the second and third water channels.

[0006] In one or more embodiments, the housing includes a cylindrical body, a lower shell, and an upper shell. A first water channel is formed inside the cylindrical body. The upper and lower ends of the annular filter screen are respectively connected to the upper shell and the lower shell. A second water channel is formed between the annular filter screen and the outer wall of the cylindrical body. The interception area is formed between the lower end of the housing and the lower shell. A third water channel is formed between the annular filter screen and the inner wall of the housing. The upper shell is detachably connected to the rear end of the housing.

[0007] In one or more embodiments, the upper shell is snapped onto the housing.

[0008] In one or more embodiments, the upper shell abuts against the upper end of the cylinder.

[0009] In one or more embodiments, both the lower shell and the upper shell are provided with a sleeve portion, which is sleeved on the outer wall of the annular filter screen.

[0010] In one or more embodiments, the cylinder and the shell are an integral structure, the cylinder is located in the middle of the shell, and the water inlet is located in the middle of the lower end of the shell, and the water inlet is in the shape of a grid.

[0011] In one or more embodiments, the water outlet is located on the upper shell, and the water outlet consists of a plurality of water outlet holes arranged around the outer edge of the upper shell.

[0012] Compared with the prior art, the advantages of this utility model are: the pre-filter, through its three-dimensional, surrounding water flow path design consisting of a first water channel, a second water channel, a retention zone, and a third water channel, combined with a ring-shaped filter screen, can efficiently separate and retain solid particles such as fish feces in the water. The feces in the water naturally settle under gravity and collect in the retention zone at the bottom, achieving centralized collection and effective removal of fish feces.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] See appendix Figure 1-2 This application provides a pre-filter for aquarium waste, which includes a housing 1, which is cylindrical in shape. The housing 1 has an outlet and an inlet 2 on its upper and lower sides, respectively. The housing 1 has a first water channel 3, a second water channel 4, a trapping zone 5, and a third water channel 6. The inlet 2 is located at the lower end of the first water channel 3. The second water channel 4 is arranged around the outside of the first water channel 3. The upper end of the first water channel 3 has a water outlet 7 that connects to the second water channel 4. The lower end of the second water channel 4 is connected to the trapping zone 5. The third water channel 6 is arranged around the outside of the second water channel 4 and is connected to the outlet. An annular filter screen 8 is arranged between the second water channel 4 and the third water channel 6. This solution, by setting up a first water channel 3, a second water channel 4, an interception zone 6, and a third water channel 6, and adopting a three-dimensional, surrounding water flow path design, allows the water flow to undergo multiple turns and flows inside the filter, extending the water flow path. When water and feces enter the second water channel 4, the water will pass through the annular filter screen 8 and enter the third water channel 6, while the feces will be intercepted by the annular filter screen 8 and sink to the interception zone 5 under the action of gravity, which facilitates subsequent cleaning and maintenance, improves filtration efficiency, and reduces the load on the water pump.

[0016] The housing 1 contains a cylindrical body 9, a lower shell 10, and an upper shell 11. A first water channel 3 is formed inside the cylindrical body 9. The upper and lower ends of the annular filter screen 8 are connected to the upper shell 11 and the lower shell 10, respectively. A second water channel 4 is formed between the annular filter screen 8 and the outer wall of the cylindrical body 9. The interception area 5 is formed between the lower end of the housing 1 and the lower shell 10. A third water channel 6 is formed between the annular filter screen 8 and the inner wall of the housing 1. The upper shell 11 is detachably connected to the rear end of the housing 1. This design makes the assembly and maintenance of the pre-filter more convenient, especially the detachable connection between the upper shell 11 and the housing 1, which facilitates cleaning and replacement of the annular filter screen 8. Furthermore, the upper shell 11 is snapped onto the housing 1, making disassembly and installation quicker and easier, requiring no tools and improving user experience and maintenance efficiency.

[0017] The upper shell 11 abuts against the upper end of the cylinder 9, which enhances the stability and sealing of the overall structure, prevents water flow short circuit or leakage, ensures that the water flows according to the designed path, and improves the filtration effect.

[0018] Both the lower shell 10 and the upper shell 11 are provided with a sleeve part 12, which is sleeved on the outer wall of the annular filter screen 8. This design can effectively fix the annular filter screen 8, prevent it from shifting or deforming during use, and at the same time enhance the sealing performance to prevent water from bypassing the filter screen 8.

[0019] The cylinder 9 and the shell 1 are an integral structure. The cylinder 9 is located in the middle of the shell 1. The water inlet 2 is located in the middle of the lower end of the shell 1. The water inlet 2 is grid-shaped, which can initially intercept larger impurities and prevent them from entering the first water channel 3. At the same time, it makes the water intake more uniform and reduces the impact of water flow.

[0020] The water outlet is located on the upper shell 11 and consists of multiple water outlet holes 13 arranged around the outer edge of the upper shell 11. The location of the water outlet on the upper shell 11 and its composition of multiple water outlet holes make the water outlet more evenly distributed.

[0021] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
