[0002] With growing environmental awareness and the widespread adoption of sustainable development concepts, people are increasingly concerned about how to effectively utilize natural resources and reduce environmental impact. The dissolution and application of carbon dioxide plays a vital role in numerous applications, such as water treatment, aquarium fish farming, and industrial processes. For example, in water treatment, injecting an appropriate amount of carbon dioxide into the water can adjust its pH. In aquarium fish farming, the proper carbon dioxide content is crucial for promoting plant growth and maintaining the ecological balance of the aquarium.
[0003] Traditional CO2 diffusion methods primarily include direct aeration and ejector methods, but these methods suffer from low efficiency, low gas utilization, and difficulty in precise control. This is particularly true for applications requiring a continuous and stable supply of a CO2 solution at a certain concentration. Furthermore, due to the lack of effective filtration, the CO2 input into the system may be contaminated with impurities, which not only affects the quality of the final product but can also cause blockages or other malfunctions within the equipment.
[0004] How to improve the dissolution efficiency of carbon dioxide, ensure the quality of the output solution while simplifying the operation process to adapt to a wider range of applications has always been a problem explored by technicians in this field.
[0005] The present utility model is made based on the above-mentioned situation. Utility Model Content

[0018] Compared with the prior art, the utility model has the following advantages:
[0019] 1. By mixing carbon dioxide gas with water, the gas forms tiny bubbles in the water, increasing the contact area between the gas and the liquid and promoting the dissolution of carbon dioxide in the water. The diffuser body and the first water supply pipe are designed as an integrated structure, simplifying the installation process and reducing the possibility of leakage.

[0022] 4. The ceramic filter element is provided with multiple air inlet holes for gas to enter the dissolved air cavity from the air inlet nozzle, and the water in the ceramic filter element will not reversely permeate out. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the accompanying drawings:
[0029] like Figures 1 to 4The carbon dioxide diffuser shown includes a diffuser body 1, which has an air dissolution chamber 11 therein. A first water supply pipe 2 communicating with the air dissolution chamber 11 is connected to the front end of the diffuser body 1. An end cap 3, which can open the air dissolution chamber 11, is detachably connected to the rear end of the diffuser body 1. A second water supply pipe 4 communicating with the air dissolution chamber 11 is connected to the end cap 3. A meter 5 is connected to the side of the diffuser body 1. A one-way air inlet valve 6 is provided on the meter 5. A filter 7 is provided between the air dissolution chamber 11 and the one-way air inlet valve 6. The diffuser body 1 and the first water supply pipe 2 are integrally formed. The first water supply pipe 2 is the water inlet pipe, and the second water supply pipe 4 is the water outlet pipe.
[0030] This solution mixes carbon dioxide gas with water, causing the gas to form tiny bubbles in the water, thereby increasing the contact area between the gas and the liquid and promoting the dissolution of carbon dioxide in the water. The diffuser body 1 and the first water supply pipe 2 are designed as an integrated structure, simplifying the installation process and reducing the possibility of leakage. This design makes the device more compact, durable, and easy to maintain. The rear end of the diffuser is detachably connected to an end cap 3 that can open the gas dissolution chamber 11, making it convenient for users to regularly clean the interior or replace components, ensuring the reliability and efficiency of the device during long-term use. The filter element 7 located between the gas dissolution chamber 11 and the one-way air inlet valve 6 can remove any impurity particles that may be present, protecting downstream components from damage, while also helping to maintain a stable carbon dioxide supply quality.
[0031] Furthermore, the end cover 3 is threadedly connected to the diffuser body 1. Of course, the end cover 3 can also be connected to the diffuser body 1 through other connection structures such as buckles or flanges.
[0032] In some embodiments, a connector 12 communicating with the gas dissolving chamber 11 is provided on the side of the diffuser body 1. A first threaded connection structure 13 is provided between the meter 5 and the connector 12, allowing the meter 5 to be detachably connected to the connector 12. This facilitates replacement of the meter 5. The meter 5 is a transparent hollow tube, and the one-way air inlet valve 6 is threadedly connected to the meter 5.
[0033] Furthermore, the angle between the central axis of the connector 12 and the central axis of the gas dissolving chamber 11 is a, 20°≤a≤60°. Injecting carbon dioxide into water at a certain angle can increase the contact time and area between the gas and water, helping to form smaller bubbles. Smaller bubbles mean a larger surface area, which helps to improve the dissolution efficiency of carbon dioxide in water. The meeting of fluids in different directions will trigger a turbulent effect, which can help disperse the gas more quickly throughout the water body, thereby achieving a more uniform mixing effect.
[0034] In one embodiment, the one-way air inlet valve 6 includes a valve cover 61 connected to the meter 5. The valve cover 61 is provided with an air inlet nozzle 62 that communicates with the meter 5. An air inlet passage 63, a check valve 64 that blocks the air inlet passage 63, and a spring 65 that presses against the check valve 64 are provided between the air inlet nozzle 62 and the meter 5. The valve cover 61 is threadedly connected to the meter 5. The check valve 64 prevents water from flowing back out of the air inlet nozzle 62.
[0035] Furthermore, the air inlet nozzle 62 is threadedly connected with a first locking nut 66 so that the air inlet nozzle 62 is locked more firmly. The first water supply pipe 2 and the second water supply pipe 4 are both threadedly connected with a second locking nut 8 so that the first water supply pipe 2 and the second water supply pipe 4 are locked more firmly.
[0036] In some embodiments, filter element 7 is a tubular ceramic filter element, provided with a plurality of inlet permeation holes for allowing air to enter the air dissolution chamber 11 from the air inlet nozzle 62. Water within the ceramic filter element is prevented from reversely permeating out. A first sealing rubber ring 701 is provided between one end of the ceramic filter element and the inner wall of the end cap 3 to restrict water flow out of this end. A second sealing rubber ring 702 is provided between the other end of the ceramic filter element and the inner wall of the air dissolution chamber 11 to restrict water flow out of this end.
[0037] In some embodiments, a first sealing ring 801 is provided between the meter 5 and the connector 12, a second sealing ring 802 is provided between the end cap 3 and the diffuser body 1, and a third sealing ring 803 is provided between the valve cover 61 and the meter 5, thereby preventing water leakage at each connection.
[0038] In one embodiment, a suction cup mount 91 is attached to the exterior of the diffuser body 1. The suction cup mount 91 is provided with a suction cup 92 for attaching the diffuser to the wall of the aquarium. Specifically, the suction cup mount 91 includes a connecting sleeve 911 and connecting legs 912 connected to the connecting sleeve 911. The connecting legs 912 are provided with mounting holes 913 for attaching the suction cup 92.
