Description

Technical Field

[0001] The utility model relates to the technical field of flat air ducts for air supply boxes, in particular to a fast-connectable flat air duct for static pressure air supply boxes. Background Art

[0002] Traditional air conditioning systems often use round or square ducts, which have significant wind resistance when conveying air and require high-power fans to ensure proper air circulation, resulting in energy waste. To reduce the system's energy consumption, people have begun to seek a more energy-efficient air delivery solution. A static pressure air box is a specially designed air delivery device. Through its unique air duct design and fan arrangement, it can generate high wind pressure, allowing the air to maintain a high velocity and stable air volume during delivery, thereby reducing the system's wind resistance and energy consumption. Flat ducts utilize a flatter design. Compared to traditional round or square ducts, flat ducts have a smaller cross-sectional area, making more efficient use of limited space. Furthermore, the inner wall of the flat duct has been optimized to reduce wind resistance, improve air delivery efficiency, and produce a more uniform wind speed distribution. Publication number: CN210921741U discloses a flat air duct of a floor static pressure air supply box, which includes an air outlet, a box body, a head, a fresh air inlet, a connector and a reinforced folded edge. The box body is provided with a head for sealing at both ends, an air outlet is provided on the top of the box body, the air duct receiving side of the box body is provided with a reinforced folded edge, and a plurality of fresh air inlets are provided on the side close to the reinforced folded edge, and a connector is plugged into the fresh air inlet. The utility model has a reasonable structural design, is easy and reliable to use, is corrosion-resistant, anti-oxidation, lead-free, rust-free, easy to clean, durable, and occupies a small space. However, as for the above-mentioned equipment, when the equipment is connected, it cannot be quickly connected, and the staff needs to connect and fix it by hand multiple times. The process is cumbersome, and the fixing effect is poor. It is easy to detach from the equipment and needs to be improved. Utility Model Content
