[0002] In the cultivation of aquatic plants and animals in aquariums and other similar facilities, filtration, aeration, and heating systems are typically installed to ensure the plants and animals can grow in a high-quality aquatic environment, thereby improving water quality and maintaining water temperature. For example, Chinese utility model patent No. 2019213500140, entitled "A Fish Tank Filter," discloses a technical solution that can simultaneously filter and aerate the water in a fish tank.

[0003] This technical solution first uses a filter tube and a sponge pad to filter the water in the aquarium, and then uses an added aeration mechanism at the outlet after filtration to oxygenate the water. Due to the location of the aeration mechanism, its contact area, contact time, and contact distance with the water are relatively small, so its oxygenation effect is not significant. Furthermore, besides requiring a motor pump at the bottom of the filter tube for water circulation, this solution also needs an air pump in the aeration mechanism to increase air pressure and oxygenate the water. In addition, aquariums and aquariums generally have lighting and heating devices for creating atmosphere, resulting in numerous components requiring power connections, which hinders wiring simplification and leads to messy wiring around the aquarium.

In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0023] like Figures 1 to 4 As shown, this aquarium pneumatic water treatment device can also be used in aquariums and fish tanks for water treatment to improve the quality of water used by aquatic plants and animals. Specifically, it includes a bottom support base 1, an air inlet pipe 2 passing through the bottom support base 1, and a middle support base 3 opposite to the bottom support base 1. A primary water treatment unit 4 is fitted between the bottom support base 1 and the middle support base 3. In use, the air inlet pipe 2 is connected to an air pump via a pipeline. The air pump pressurizes the air and delivers it through the air inlet pipe 2 and the primary water treatment unit 4 towards the middle support base 3. As the pressurized gas passes through the primary water treatment unit 4, external water enters the unit and rises synchronously with the airflow, mixing with the gas during this process, thus achieving initial pressurization.

[0024] Specifically, the bottom support 1 includes a bottom support enclosure 101 with an opening at the bottom end. The top of the bottom support enclosure 101 has a recessed limiting support groove 102. The lower end of the primary water treatment unit 4 is supported in the limiting support groove 102. The air inlet pipe 2 passes through the limiting support groove 102 and extends into the primary water treatment unit 4. The bottom end of the bottom support enclosure 101 is provided with a pipe opening 103 for cooperating with the air inlet pipe 2. The pipeline connecting the air inlet pipe 2 and the air pump is laid through the pipe opening 103. Several water inlets 104 can also be arranged at the bottom end of the bottom support enclosure 101 to achieve water pressure balance inside and outside the bottom support enclosure 101, so as to ensure the stability of the contact between the bottom support enclosure 101 and the bottom wall of the aquarium.

[0025] The central support base 3 includes a central support cover 301 with a top opening. A through hole is provided through the bottom wall of the central support cover 301. A limiting protrusion ring 302 is provided on the bottom wall of the central support cover 301 around the through hole and protruding towards the bottom support base 1. The top of the primary water treatment unit 4 is fitted with the limiting protrusion ring 302. With the cooperation of the limiting protrusion ring 302 and the limiting support groove 102, the primary water treatment unit 4 is limited and supported. The components are assembled and disassembled by fitting, which is simple and convenient and easy to maintain.

[0026] The primary water treatment unit 4 in this embodiment includes a primary water-passing cylinder 401 with openings at both ends. Water-passing holes are arranged through the cylinder wall of the primary water-passing cylinder 401. The primary water-passing cylinder 401 is supported between the bottom support 1 and the middle support 3. A filter cotton 402 is fitted around the outside of the primary water-passing cylinder 401. Water filtration media can also be filled inside the primary water-passing cylinder 401 to improve the filtration effect. In use, under the action of airflow, external water passes through the filter cotton 402 and the water-passing holes into the primary water-passing cylinder 401, and moves upward under the drive of the airflow, realizing pneumatic circulation of water. The filter cotton 402 can be a large single piece or several smaller pieces stacked together. Some impurities in the external water will enter the filter cotton 402 and be intercepted. After a period of use, the bottom support 1 and the middle support 3 can be disassembled, and the filter cotton 402 can be replaced.

[0027] A top cover 5 is provided opposite to the central support base 3. A secondary water treatment unit 6 is fitted between the central support base 3 and the top cover 5. A water outlet pipe 7 is fitted on the top cover 5. The air inlet pipe 2, the primary water treatment unit 4, the central support base 3, the secondary water treatment unit 6, and the water outlet pipe 7 are sequentially connected. The top cover 5 cooperates with the central support base 3 to limit the assembly of the secondary water treatment unit 6, and the three parts are easily disassembled for easy maintenance of the secondary water treatment unit 6.

[0028] The inner top wall of the encapsulation top cover 5 is provided with an inner limiting ring 501 that protrudes towards the central support 3, and the outer top wall of the encapsulation top cover 5 is provided with an outer limiting ring 502 that protrudes outward. The inner limiting ring 501 is used to limit the assembly of the secondary water treatment unit 6, and the outer limiting ring 502 is used to limit the assembly of the water outlet pipe 7. The secondary water treatment unit 6 includes a water treatment outer cylinder 601 with an opening at the top, and the water treatment outer cylinder 601 is located between the central support 3 and the encapsulation top cover 5. A secondary water-passing cylinder 602 is fitted inside the water treatment outer cylinder 601. Water-passing holes are arranged in the cylinder wall of the secondary water-passing cylinder 602. A filter media filling gap 603 is formed between the secondary water-passing cylinder 602 and the water treatment outer cylinder 601. Through holes communicating with the secondary water-passing cylinder 602 and the filter media filling gap 603 are respectively provided in the bottom wall of the water treatment outer cylinder 601. A limiting inner ring 604 is also provided on the inner bottom wall of the water treatment outer cylinder 601 for fitting with the secondary water-passing cylinder 602. Specifically, the upper end of the water treatment outer cylinder 601 is fitted with the inner limiting ring 501 of the top cover, and the lower end of the water treatment outer cylinder 601 is fitted with the limiting inner ring 604.

[0029] The secondary water passage 602 and the filter media filling gap 603 are respectively filled with water treatment filter media blocks 605. For example, the filter media blocks 605 filled in the filter media filling gap 603 can be used as MBBR fluidized bed packing for bacterial cultivation and biofilm formation, while the filter media blocks 605 filled in the secondary water passage 602 can be used as quartz ball filter media for culturing and digesting bacteria. Furthermore, the water treatment outer cylinder 601 is made transparent, allowing observation of the agitation of the MBBR fluidized bed packing within the filter media filling gap 603 due to water flow, thus enhancing its visual appeal. Figure 3 To facilitate the display of the main structure of this device, the relevant filter media schematic structure is not shown in the primary water passage 401 and the secondary water passage 602.

[0030] The water outlet pipe 7 includes a riser section 701 that is assembled and connected to the encapsulated top cover 5. The top end of the riser section 701 is connected to a horizontal pipe section 702, and the cavity of the horizontal pipe section 702 gradually expands outward from the riser section 701 to increase the water distribution effect. In this embodiment, an auxiliary fixing device is also provided on the outer wall of the bottom support 1 and / or the middle support 3 to assist in fixing the entire device. Specifically, the auxiliary fixing device includes a suction cup mounting seat 8 for mounting a suction cup and / or an arc-shaped arm 9 for assembling with a round rod or round tube. When the suction cup is assembled using the suction cup mounting seat 8, the suction cup can be used to assist in fixing by adsorption between the suction cup and the inner wall of the aquarium. When the arc-shaped arm 9 is provided, it can be used to encircle the pipes in the aquarium to achieve the function of auxiliary fixing.

[0031] The specific water treatment process in this embodiment is as follows:

[0032] First, pressurized gas is pumped into the primary water-passing cylinder 401 through the air inlet pipe 2. As the pressurized gas rises, external water enters the primary water-passing cylinder 401 through the filter cotton 402 and the water passage holes. During its journey, the water is initially filtered by the filter cotton 402 and the filter media filled in the primary water-passing cylinder 401. The water then enters the middle support enclosure 301, where the increased space allows for buffered mixing of the water and gas. Finally, the water enters the filter media filling gaps 6 through the holes on the bottom wall of the water treatment outer cylinder 601. In the secondary water passage 602 and the secondary water passage 603, the water pressure is slightly increased due to the small holes on the bottom wall of the outer water treatment cylinder 601. The water entering the filter media filling gap 603 is used for bacterial cultivation and biofilm formation by the MBBR fluidized bed packing. The water entering the secondary water passage 602 is used for bacterial cultivation by the quartz ball filter media. The water in the filter media filling gap 603 eventually enters the secondary water passage 602, mixes with the water in the secondary water passage 602 to complete water treatment, and is discharged into the aquarium through the outlet pipe 7.
