The invention discloses a pull rope transmission mechanism. The pull rope transmission mechanism is characterized in that an output connector capable of keeping rectilinear movement with a pull rope is installed on the pull rope; a radial lug is arranged at the periphery of a drive wheel assembly; a first limit block and a second limit block are arranged on an installation plate; the rotation range of the radial lug is limited between the first limit block and the second limit block, and in the state that the radial lug is abutted against the first limit block, the output connector is located at the lowest position; and in the state that the radial lug is abutted against the second limit block, the output connector is located at the highest position. The invention further discloses a range hood. The stroke of the pull rope transmission mechanism is limited through the first limit block and the second limit block, large-stroke movement can be realized, low cost is achieved, and a load can further be driven to stably move through the rectilinear movement of the output connector in the pull rope; and the range hood provided with the transmission mechanism is capable of driving lifting rods at the two sides of an installation frame to carry out synchronous lifting movement through the transmission mechanism, and then enabling a smoke guide plate to keep stable and vertical movement.
Description
technical field [0001] The invention relates to a range hood, in particular to a pull rope transmission mechanism and a range hood using the mechanism. Background technique [0002] At present, in order to improve the range hood's oil absorption effect, people have invented various range hoods with movable smoke deflectors. The air inlet angle and air volume of the range hood. For example, "European range hood with automatic smoke guide plate" disclosed in the Chinese utility model patent whose patent number is 201620042811.2 (authorized announcement number is CN 205372692U), the range hood includes a smoke guide plate and a fixed plate, and one side of the fixed plate There is a fixed guide rail, and a matching moving guide rail is provided inside the fixed guide rail. A transmission rod is arranged beside the fixed guide rail. The transmission rod is offset against the moving guide rail. There is a fixed bracket at the lower end of the guide rail, and the fixed bracket i...
