Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a filtration and purification device for aquariums. Background Technology

[0002] With the development of spiritual civilization, material life can no longer meet the needs of the times. As people's spiritual life continues to improve, aquariums are gradually entering thousands of households in order to cultivate their sentiments. While aquariums can certainly cultivate sentiments, problems also arise. Maintaining good water quality is not so easy. Fish excrement and leftover food scraps pose a great threat to water quality. Therefore, a good aquarium filter is an essential configuration.

[0003] The existing technology has the following problems:

[0004] 1. Existing filtration and purification devices for aquariums: Most existing aquarium filters use water pumps placed inside the tank, resulting in messy wires and pipes inside the tank. At the same time, integrated tank and filter filters on the market cannot achieve dry and wet separation, and fish excrement and food residue accumulate at the bottom of the tank, affecting water quality and making it difficult to clean. Some filters that can achieve dry and wet separation are small in size, resulting in a small amount of filter media that is not suitable for slightly larger aquariums. Filters for cultivating bacteria, rain-type non-storage filters have low efficiency, and the overall viewing effect is poor when placed in the tank, which also reduces the space for fish to move around.

[0005] 2. Existing filtration and purification devices for aquariums typically consist of a basic filtration system consisting of a water pump, a cable connected to the water pump, an outlet pipe, and a filter box. When these components are distributed inside or above the tank, they compress the viewing space and the space for the fish to move around, greatly reducing the viewing effect. Utility Model Content

The fish water, after the impurities are separated, flows down through the permeable baffle. Through a unique return water pipe design, the water flow path is changed so that the water flows from top to bottom through several layers of bio-filter media baffles and the filter media inside the filter chamber to the bottom. Then, it is gathered through the bottom guide base. Due to the water pressure difference, the fish water flows back up from the bottom of the return water pipe. When the water level in the filter canister does not reach the horizontal line of the outlet pipe, water is stored. The fish water fully contacts the filter media to improve the bacterial cultivation efficiency. When the water level in the filter canister reaches the horizontal line of the outlet pipe, due to the water level connector principle, the water flows out naturally from the single outlet pipe, achieving dry and wet separation and improving the filtration effect.

[0017] 2. This utility model provides a filtration and purification device for aquariums. It is equipped with threaded fittings, connectors, connecting pipes, and an oil-removing film float head. Fish water on the surface of the tank passes through the oil-removing film float head, while fish water at the bottom of the tank is pumped to the rain pipe by a water pump through a reverse structure. The water then flows evenly into the filter canister through the rain holes at the bottom of the rain pipe. Only the reverse structure and the oil-removing film float head remain inside the tank. By placing the filter canister, water pump, and outlet pipe on the outside of the tank, the space occupied inside the tank is reduced, thereby increasing the activity space for the fish and improving the viewing effect. It is also more aesthetically pleasing to use. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1

[0028] like Figure 1-7As shown, this utility model provides a filtration and purification device for an aquarium, including a filter canister 1 and a tank body 18. A cover plate 2 is movably installed on the top of the filter canister 1, and a base 3 is movably installed on the bottom of the filter canister 1. A water pipe 4 is fixedly connected to the upper left side of the filter canister 1, and a water pump 6 is fixedly connected to the other end of the water pipe 4. A second water pipe 5 is fixedly connected to the side of the water pump 6. A return water pipe 7 is fixedly installed at the lower end inside the filter canister 1. A water outlet pipe 8 is fixedly connected to the middle right side of the filter canister 1, and the water outlet pipe 8 and the return water pipe 7 are interconnected. An internally threaded drain outlet 9 is fixedly connected to the bottom of the filter canister 1. An air pressure balance hole 11 is opened in the middle of the cover plate 2. A rain shower pipe 12 connected to the water pipe 4 is fixedly installed at the top inside the filter canister 1. A water-permeable... A baffle 13 is fixedly connected to the middle of the top of the permeable baffle 13. A filter material 15 is movably snapped onto the top of the permeable baffle 13. Biochemical filter media baffles 16 are fixedly installed at equal intervals inside the lower end of the filter barrel 1. A filter chamber 17 is provided between the biochemical filter media baffles 16. A reversing structure 19 is fixedly connected to the bottom of the cylinder body 18. An installation part 20 is fixedly installed at the bottom of the reversing structure 19. A cyclone guide vane 21 is fixedly installed inside the reversing structure 19. A threaded pipe fitting 22 connected to the installation part 20 is fixedly installed at the bottom of the cylinder body 18. The threaded pipe fitting 22 is connected to the water pipe 5. A connector 23 is fixedly connected to the top of the reversing structure 19. A connecting pipe 24 is fixedly connected to the top of the connector 23. An oil removal film float head 25 is movably connected inside the connecting pipe 24.

[0029] In this implementation case, the optimal shape of the tank 18 during use is circular, with an open bottom design. After the inverted structure 19 is installed at the bottom of the tank 18, when the water pump 6 is turned on, a vortex is formed at the bottom of the tank 18, which quickly sucks in fish excrement and food residue, and pumps it into the filter canister 1 by the water pump 6. The fish water containing dirt is evenly sprayed into the upper filter media 15 through the rain pipe 12, and the impurities in the fish water are fully intercepted and separated. The fish water with separated impurities is then filtered and absorbed by the multi-layered and multi-purpose biological filter media in the lower filter chamber 17. The design of the return water pipe 7 ensures that the water level below the horizontal line of the outlet pipe 8 is the storage water level, and the fish water is in full contact with the filter media to achieve a better filtration effect.

[0030] Example 2

[0031] like Figure 1-7 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the threaded pipe fitting 22 has an internal opening and its outer side is integrally formed in a T shape. The threaded pipe fitting 22 penetrates the cylinder body 18 and is threadedly connected to the mounting part 20, and a rubber sealing ring is provided on its outside. The threaded pipe fitting 22 and the cylinder body 18 are sealed together.

[0032] In this embodiment, by providing threaded pipe fittings 22, connectors 23, connecting pipes 24, and oil-removing film floats 25, the fish water on the surface of the tank 18 passes through the oil-removing film floats 25, and the fish water at the bottom of the tank is drawn by the water pump 6 through the inverted structure 19 to the rain pipe 12. The rain pipe 12 then flows evenly into the filter canister 1 through the rain holes at the bottom for use. Only the inverted structure 19 and the oil-removing film floats 25 remain inside the tank 18. By placing the filter canister 1, water pump 6, and water outlet pipe 8 on the outside of the tank 18, the space occupied inside the tank 18 is reduced, thereby increasing the activity space for the fish and the viewing effect, making it more aesthetically pleasing to use.

[0033] The working principle of this filtration and purification device for aquariums will be explained in detail below.

[0034] like Figure 1-7 As shown, the inverted structure 19, which is fixedly and sealed at the bottom of the tank 18, can quickly suck out fish excrement and food residue from the tank 18 without blind spots. The cyclone guide vane 21 improves the suction efficiency. Then, the fish water is drawn into the filter canister 1 through the external water pipe 2 5 via the water pump 6. The filter canister 1 has a dry and wet layout. The upper end of the filter canister 1 has a ring-shaped rain pipe 12. The rain holes at the lower end of the rain pipe 12 can evenly spray out the fish water containing impurities. Then, it passes through the filter media 15 outside the overflow pipe 14, and the impurity particles are physically filtered and separated by the filter cotton and biochemical cotton. Impurities in the fish water flow down through the permeable baffle 13. Through the unique design of the return water pipe 7, the water flow path is changed so that the water flows from top to bottom through several layers of biochemical filter media baffles 16 and the filter media inside the filter chamber 17 to the bottom. Then it is gathered through the bottom guide base 10. Due to the water pressure difference, the fish water flows back up from the bottom of the return water pipe 7. When the water level in the filter canister 1 does not reach the horizontal line of the outlet pipe 8, water is stored. The fish water fully contacts the filter media to improve the bacterial cultivation efficiency. When the water level in the filter canister 1 reaches the horizontal line of the outlet pipe 8, due to the water level connector principle, the water flows out naturally from the only outlet pipe 8, achieving dry and wet separation and improving the filtration effect.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
