Description

Technical Field

[0001] The utility model belongs to the technical field of fish tank filtering, in particular to a fish tank filtering box. Background Art

[0002] A fish tank is a container for living fish. The tank body is transparent and mostly made of glass. It can be used to raise fish for ornamental purposes. The water in the fish tank is "dead water". Long-term use will cause water quality problems and it is not suitable for fish life. The water in the fish tank needs to be replaced regularly. In order to extend the replacement cycle of fish farming water, a fish tank filter box can be used to filter the water.

[0003] After searching, the patent with application number 202321275464.4 discloses a fish tank filter box. This patent is convenient to use by setting a cover plate, a fixed ring belt and multiple partitions to facilitate the replacement and cleaning of different filter elements. However, since several filter chambers are connected and horizontal, after the water pump passes the water through the water inlet pipe and the connecting pipe through each filter chamber in turn, the water body will have a backflow phenomenon during the filtration process, thereby causing secondary pollution of the water body and resulting in poor filtration effect. Based on this, a fish tank filter box is proposed. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a fish tank filter box. By arranging a slope in the box body, and the inclination angle of the slope is from left to right downward, when the water passes through the first filter frame, the second filter frame and the third filter frame in sequence, it will not cause water backflow or reflux, thereby avoiding secondary or multiple pollution of the water body and ensuring the filtering effect. By arranging card strips on the slope that are respectively engaged with the two sides of the bottom of the first filter frame, the second filter frame and the third filter frame, not only is it convenient to install and disassemble each filter frame separately, but also it avoids the trouble of impurities in the consumables being left in the box when different filter consumables are directly taken out of the box.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, the slope is provided with clips that are respectively engaged with both sides of the bottom ends of the first filter frame, the second filter frame and the third filter frame. By providing the clips that are respectively engaged with both sides of the bottom ends of the first filter frame, the second filter frame and the third filter frame on the slope, it is not only convenient to install and disassemble each filter frame separately, but also avoids the trouble of impurities in the consumables being left in the box when different filter consumables are directly taken out of the box.

[0008] Furthermore, the bottoms of the first filter frame, the second filter frame and the third filter frame are all structures inclined downward from left to right, and the bottoms of the first filter frame, the second filter frame and the third filter frame are in contact with the inclined surface of the slope. Since the bottoms of the first filter frame, the second filter frame and the third filter frame are all structures inclined downward from left to right, they are easy to adapt to the inclined surface of the slope.

Example

[0017] See attached Figure 1-2 As shown, a fish tank filter box comprises a box body 1; a box cover 2 is provided on the upper side of the box body 1, a slope 3 is provided on the left side of the inner cavity of the box body 1, the inclination angle of the slope 3 is downward from left to right, and a first filter frame 4, a second filter frame 5 and a third filter frame 6 are provided on the slope 2 from left to right in sequence, a honeycomb cotton is detachably installed in the first filter frame 4, a biochemical cotton is detachably installed in the second filter frame 5, and aquatic plants and sand are provided in the third filter frame 6. A water inlet pipe 7 is installed at the water inlet at the upper left end of the box body 1, and a drain pipe 8 is installed at the drain outlet at the bottom right end of the box body 1. By arranging the slope 3 in the box body 1, and the inclination angle of the slope 3 is downward from left to right, when the water passes through the first filter frame 4, the second filter frame 5 and the third filter frame 6 in sequence, it will not cause the water to flow back or reflux, thereby avoiding secondary or multiple pollution of the water and ensuring the filtering effect.

[0018] The slope 3 is provided with clamping strips 9 which are respectively clamped with both sides of the bottom ends of the first filter frame 4, the second filter frame 5 and the third filter frame 6. By providing the clamping strips 9 which are respectively clamped with both sides of the bottom ends of the first filter frame 4, the second filter frame 5 and the third filter frame 6 on the slope 3, it is not only convenient to install and disassemble each filter frame separately, but also avoids the trouble of impurities in the consumables being left in the box body 1 when directly taking out different filter consumables in the box body 1.

[0019] The bottoms of the first filter frame 4, the second filter frame 5 and the third filter frame 6 are all inclined downward from left to right, and the bottoms of the first filter frame 4, the second filter frame 5 and the third filter frame 6 are in contact with the inclined surface of the slope 3. Since the bottoms of the first filter frame 4, the second filter frame 5 and the third filter frame are all inclined downward from left to right, they are easy to adapt to the inclined surface of the slope 3.

[0020] Working principle: The water in the fish tank enters the box body 1 through the water inlet pipe 7, and the large particles of impurities such as fish feces and food residues are filtered out by the honeycomb cotton in the first filter frame 4. Then the water body continues to flow downward, and the biochemical cotton in the second filter frame 5 helps to decompose the harmful substances in the water to maintain the cleanliness and stability of the water quality. The water body continues to flow downward, and when passing through the water grass sand in the third filter frame 6, the sand can be used to cultivate water grass, and the water grass can produce oxygen through photosynthesis, thereby increasing the oxygen content of the water body. Finally, the filtered water body is discharged through the drain pipe 8. By setting a slope 3 in the box body 1, and the inclination angle of the slope 3 is from left to right downward, the water body passes through the first filter frame in sequence. When the filter frame 4, the second filter frame 5 and the third filter frame 6 are filtered, no backflow or reflux of water will occur, thereby avoiding secondary or multiple pollution of the water and ensuring the filtering effect. By arranging the card strips 9 on the slope 3 to be respectively engaged with the two sides of the bottom of the first filter frame 4, the second filter frame 5 and the third filter frame 6, it is not only convenient to install and disassemble each filter frame separately, but also avoids the trouble of impurities in the consumables being left in the box body 1 when different filter consumables are directly taken out of the box body 1. Since the bottoms of the first filter frame 4, the second filter frame 5 and the third filter frame 6 are all inclined downward from left to right, they are easy to adapt to the inclined surface of the slope 3.

[0021] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.
