Description

Technical Field

[0001] The utility model relates to the technical field of check valves, in particular to a kitchen flue check structure. Background Art

[0002] The range hood is a commonly used smoke exhaust device in every household. In order to prevent the backflow of oil smoke, a check valve is installed at the end of the range hood exhaust pipe. During the installation of the existing check valve and the flue, a cable tie is passed through the two ends of the check valve fixing plate, and a steel wire is passed through the ends of the two cable ties. Finally, the cable tie is pulled to make the steel wire contact with the flue, and then the fixing glue of the check valve base is used to complete the installation of the check valve and the flue. However, in this process, the cable tie will directly touch the valve leaf due to its long length, affecting the subsequent use of the check valve. Therefore, tools are generally required to cut the cable tie. However, the check valve is generally installed at a high place in the house. Therefore, when workers are working, two people are required to work together, one to install and the other to pass the tool, which is not convenient enough. Utility Model Content
