Smoke guide plate lifting mechanism of range hood

Abstract

The invention discloses a smoke guide plate lifting mechanism of a range hood. The smoke guide plate lifting mechanism of a range hood comprises a mounting frame, a driving mechanism, lifting rods and a smoke guide plate, wherein the driving mechanism is arranged on the mounting frame, the smoke guide plate is arranged on the lower end of the lifting rod, the driving mechanism drives the lifting rod and the smoke guide plate to do lifting motion; the smoke guide plate lifting mechanism of a range hood is characterized in that the driving mechanism is an electric winch mechanism, at least two lifting rods are provided and the lifting rods are provided on the left side and the right side of the mounting frame, the electric winch mechanism is provided with two power output ends, the two power output ends are located on the left side and the right side of the mounting frame respectively, and meanwhile, the power output ends can drive the lifting rods on the two sides to perform synchronous lifting motion. The smoke guide plate lifting mechanism of the range hood has the advantages that the electric winch mechanism is adopted for the driving mechanism of the smoke guide plate lifting mechanism, the two power output ends of the electric winch mechanism are located on the left side and the right side of the mounting frame respectively, the power output ends provide power for moving up and down and drive the lifting rods on the two sides to perform synchronous lifting motion, and therefore the smoke guide plate can keep stable motion.

Description

technical field [0001] The invention relates to a range hood, in particular to a smoke guiding plate lifting mechanism of the range hood. 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 by the Chinese utility model patent No. 201620042811.2 (authorized announcement number is CN205372692U). There is a fixed guide rail, and there is a matching moving guide rail inside the fixed guide rail. There is a transmission rod next to the fixed guide rail. The transmission rod is offset against the moving guide rail. There is a fixed bracket at the lower end, the fixed bracket is offset against the smoke guide plate, the transmission rod is provided with a connecting rod, the connecting rod is placed on the moving guide rail, and t...

AI Technical Summary

Problems solved by technology

[0003] Although the existing range hoods can greatly improve the range hood effect by setting the lifting mechanism to drive the smoke guide plate to move up and down, but generally there is a phenomenon that the smoke guide plate does not move smoothly enough, and the user experience is poor.
