Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically to a quick-release connector for a flue pipe. Background Technology

[0002] Flue gas ducts generally refer to duct systems used to exhaust fumes or waste gases generated in industrial or domestic settings. In homes, especially in kitchen exhaust systems, flue gas ducts play a crucial role, effectively removing cooking fumes and heat to the outside and maintaining fresh indoor air. In household applications, cleaning and replacing flue gas ducts requires disassembling and reassembling the ducts and their connecting pipes. If the flue gas duct is directly connected to the exhaust fan with tape, the tape must be removed when disassembling the range hood, which is inconvenient. Therefore, current technology typically uses quick-release couplings to connect the ducts.

[0003] For example, Chinese utility model patent No. 202121791166.1 (authorization announcement No. CN215445492U) discloses a pipe connection structure, including a connector body with a locking protrusion ring. The locking protrusion ring has a retractable locking structure, which can be radially extended and retracted along the locking protrusion ring to form a locked and unlocked state. The quick-release pipe connector includes a quick-release top pressure ring and the aforementioned pipe connection structure, wherein the quick-release top pressure ring is used to squeeze and open the locking structure. This utility model has a complex structure, requiring the quick-release top pressure ring to squeeze and open the locking structure to achieve quick release. The resistance of the opening component is relatively large, which is time-consuming and laborious, and inconvenient for rapid disassembly. Utility Model Content
