Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration equipment technology, and in particular to a filter. Background Technology
[0002] Due to the presence of leftover food, fish waste, algae, and other factors, the water in aquariums can gradually become cloudy if no water quality intervention is performed over a long period, affecting the survival and visual appeal of the fish. Therefore, the common practice is to install a filter in the aquarium. The filter circulates and filters the water to remove cloudy impurities, ensuring that the water quality in the aquarium remains good.
[0003] For a typical filter, the aquarium water is filtered only through the filter cotton inside the filter. However, in addition to fine impurities, there are also large particles of fish feces and other dirt in the water. These large particles of dirt can easily clog the filter cotton, resulting in reduced water flow, decreased filtration flow, and failure of physical filtration. Utility Model Content

In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0039] like Figures 1 to 3 As shown, a preferred embodiment of this utility model discloses a filter, including a filter box 10, a sludge collection bucket 20, a first filter assembly 30, and a second filter assembly 40. The filter box 10 is provided with an inlet pipe 13 and an outlet pipe 14. A first filter chamber 11 and a second filter chamber 12 are formed in the filter box 10 in sequence. The first filter assembly 30 is disposed in the first filter chamber 11, and the second filter assembly 40 is disposed in the second filter chamber 12. The sludge collection bucket 20 is installed on the filter box 10. The sludge collection bucket 20 is provided with a filter screen bucket 21 and a sedimentation space 22. The filter screen bucket 21 is located in the sedimentation space 22. The bottom of the sedimentation space 22 is provided with a drain outlet 221. The outlet of the filter screen bucket 21 is connected to the first filter chamber 11. The filter screen bucket 21 is connected to the sedimentation space 22 through the filter screen structure. The inlet pipe 13 is connected to the sedimentation space 22, and the outlet pipe 14 is connected to the second filter chamber 12. The filter bucket 21 is, for example, a cylindrical rigid tube with a large number of small through holes. The small through holes can block large particles of dirt, so that the large particles of dirt are blocked in the sedimentation space 22.
[0040] Combination Figure 4 and Figure 5 A water-passing plate 50 is provided between the sludge collection bucket 20 and the filter box 10. The filter screen bucket 21 is fixed on the water-passing plate 50. The upper end through hole of the filter screen bucket 21 is connected to the water-passing hole 51 on the water-passing plate 50. The water-passing hole 51 is connected to the first filter chamber 11. The water inlet pipe 13 is connected to the sedimentation space 22 through the water-passing plate 50. The filter screen bucket 21 can be clamped and fixed by the interference fit of the inner wall of the water-passing hole 51. The water-passing plate 50 is provided with a bent flow channel 52. The bent flow channel 52 is located on the side of the water-passing plate 50 close to the sedimentation space 22. The water inlet pipe 13 is located on the other side of the water-passing plate 50. One end of the bent flow channel 52 is connected to the water inlet pipe 13, and the other end is connected to the sedimentation space 22. The opening of the bent flow channel 52 connected to the sedimentation space 22 faces the circumference of the filter screen bucket 21 and is not directly opposite the filter screen bucket 21. The bend in the flow channel 52 creates a vortex in the water entering the sedimentation space 22, causing large particles of waste, such as fish feces, to be thrown to the periphery of the sedimentation space 22 and gradually deposited, preventing them from directly hitting the filter screen 21. Additionally, a funnel 222 is located at the bottom of the sedimentation space 22, with a drain outlet 221 at the bottom, allowing large particles of waste to concentrate more quickly at the drain outlet 221.
[0041] The filter also includes a connecting cover 60, the sludge collection tank 20 is fixed to the filter box 10 through the connecting cover 60, the water inlet 63 of the connecting cover 60 is connected to the water inlet pipe 13 and the bend flow channel 52, the water outlet 64 of the connecting cover 60 is connected to the first filter chamber 11 and the water passage hole 51, and the hole wall of the water passage hole 51 of the water passage plate 50 covers the outer wall of the water outlet 64 of the connecting cover 60.
[0042] The connecting cover 60 includes a mounting cover 61 and a threaded knob 62. The mounting cover 61 is fixed to the filter box 10 by means of snap-fit or fastener connection. The threaded knob 62 is threadedly connected to the mounting cover 61. The threaded knob 62 is fitted onto the top of the sludge collection tank 20 and presses upward against the top of the sludge collection tank 20. The threaded knob 62 is screwed into the mounting cover 61 to fix the sludge collection tank 20 onto the mounting cover 61. Specifically, the top edge of the sludge collection tank 20 forms a stepped surface 23. The bottom of the threaded knob 62 presses upward along the axial direction against the stepped surface 23 of the sludge collection tank 20, so that the sludge collection tank 20 is pressed and fixed onto the mounting cover 61. The water-passing plate 50 overlaps the upper side wall of the sedimentation space 22. Specifically, the threaded knob 62 catches the stepped surface 23 and is threaded into the mounting cover 61, so that the top of the sludge collection tank 20 is firmly clamped between the mounting cover 61 and the threaded knob 62, while the water-passing plate 50 is pressed against the mounting cover 61.
[0043] The filter box 10 has a transition chamber 15 located above the sedimentation space 22. An installation port 16 is provided on the bottom side of the filter box 10, and a sludge collection bucket 20 is installed at the installation port 16, which faces the transition chamber 15. The outlet of the filter screen bucket 21 communicates with the transition chamber 15. The transition chamber 15 communicates with the top side of the first filter chamber 11, while the second filter chamber 12 is located on the side of the first filter chamber 11 away from the transition chamber 15. The first filter chamber 11 and the second filter chamber 12 are separated by a partition 70. The mounting cover 61 can be fixed to the periphery of the installation port 16 of the transition chamber 15 using fasteners. A portion of the inlet pipe 13 is located within the transition chamber 15, but it is separated from both the transition chamber 15 and the filter screen bucket 21.
[0044] The first filter assembly 30 is wrapped around the periphery of the first pipe 31, and the second filter assembly 40 is wrapped around the periphery of the second pipe 41. The first pipe 31 and the second pipe 41 are connected, and the first filter chamber 11 and the second filter chamber 12 are separated by a partition 70. Further, the filter also includes a bottom pipe 80, one end of which extends into the first filter chamber 11, and the other end extends into the second filter chamber 12. The bottoms of the first pipe 31 and the second pipe 41 are detachably fixed to the two ends of the bottom pipe 80. The bottom of the first pipe 31 has a protruding bottom plate, and the first filter assembly 30 overlaps the bottom plate of the first pipe 31, allowing the first filter assembly 30 to be lifted along with the first pipe 31. The bottom of the second pipe 41 also has a protruding bottom plate, and the second filter assembly 40 overlaps the bottom plate of the second pipe 41, allowing the second filter assembly 40 to be lifted along with the second pipe 41. The bottom plates of the first pipe 31 and the second pipe 41 can each be annular structures.
[0045] Specifically, in some embodiments, the first filter assembly 30 is a series of stacked annular filter cotton, which is fitted onto the first pipe 31, and the sidewall of the first pipe 31 is connected to the first filter assembly 30; the second filter assembly 40 is a series of stacked annular filter cotton or culture bricks, which is fitted onto the second pipe 41, and the sidewall of the second pipe 41 is connected to the second filter assembly 40. The main purpose of the culture bricks is as a filter material for aquariums, which can purify water quality and provide a good living environment for fish. The culture bricks usually contain nitrifying bacteria, which can decompose harmful substances in the aquarium and maintain the cleanliness and stability of the water quality. The first pipe 31 and the second pipe 41 are connected by a bottom channel 80 located at the bottom of the cavity, and other areas are blocked by structures such as partitions 70 to separate the first filter chamber 11 and the second filter chamber 12.
[0046] Two caps 90 are detachably mounted on the top of the filter box 10. The two caps 90 are located above the first filter chamber 11 and the second filter chamber 12, respectively. The axial projections of the first filter assembly 30 and the second filter assembly 40 are smaller than the projections of the caps 90. By removing the caps 90, the first pipe 31 and the second pipe 41 can be lifted, thereby removing the corresponding first filter assembly 30 (attached to the first pipe 31) and second filter assembly 40 (attached to the second pipe 41). Specifically, the two caps 90 are detachably mounted on the cover plate 19 of the filter box 10. The caps 90 can be fixed to the cover plate 19 by threads, snaps, or other means.
[0047] A water pump 17 is provided in the second filter chamber 12. The inlet of the water pump 17 is connected to the second filter chamber 12, and the outlet of the water pump 17 is connected to the outlet pipe 14. Specifically, the water pump 17 is located at the top of the second filter chamber 12. The water pump 17 can be fixed on the cap 90 above the second filter chamber 12 and can be removed / installed together with the cap 90.
[0048] In this specific embodiment, the inlet pipe 13 and the outlet pipe 14 are respectively located on the side wall of the filter box 20, which helps to reduce the overall size of the filter. A wall-mounting block 18 is provided on the side wall of the filter box 10, and the inlet pipe 13 and the outlet pipe 14 are respectively located on the wall-mounting block 18, which allows the entire filter to be hung on the outside of the glass wall of the aquarium, while the inlet pipe 13 and the outlet pipe 14 are located inside the aquarium to realize water inlet and outlet. Specifically, the inlet pipe 13 is connected to and communicates with the transition cavity 15, and the outlet pipe 14 is connected to and communicates with the second filter cavity 12. The transition cavity 15, the first filter cavity 11, and the second filter cavity 12 are sequentially interconnected, so that a water flow channel is formed between the inlet pipe 13 and the outlet pipe 14.
[0049] refer to Figure 3 and Figure 6 The red arrows in the diagram indicate the overall water flow process of the filter in this preferred embodiment: Water entering through the inlet pipe 13 first enters the sludge collection tank 20, undergoes preliminary filtration through the filter screen 21 of the sludge collection tank 20, filtering out large particles of dirt, such as fish feces, which fall into the sedimentation space 22 and collect in the funnel 222 at the bottom of the sedimentation space 22, and can be discharged through the drain outlet 221; the filtered water then enters the interior of the filter screen 21. The water that has undergone coarse filtration from the sludge collection tank 20 enters the transition chamber 15 from the upper end of the filter screen 21, then enters the upper part of the first filter chamber 11, is filtered again by the first filter assembly 30, and then enters the first pipe 31, then enters the second pipe 41 through the bottom pipe 80, then flows through the side wall of the second pipe 41 through the second filter assembly 40 and enters the second filter chamber 12, and finally is drawn by the water pump 17 at the top of the second filter chamber 12 and discharged from the outlet pipe 14. When it is necessary to clean up the accumulated fish feces, the drain outlet 221 is opened, and the fish feces deposited at the bottom of the sedimentation space 22 can be flushed out with the water flow. The drain outlet 221 can be sealed by a rubber plug, screw cap or other structure.
