AI Technical Summary

Technical Problem

In existing range hoods, how to effectively and labor-savingly drive the smoke deflector to move, especially how to simultaneously drive the movable structures of the left and right smoke deflectors, has not been fully disclosed and implemented.

Method used

A transmission assembly design is adopted, including a first connecting rod and a second connecting rod. The output end of the power part acts on the upper end of the first connecting rod, and the smoke shield is driven to move left and right through the rotation of the connecting rod. The rotation center of the first connecting rod in the transmission assembly is designed to be close to the upper end and away from the lower end, so that the smoke shield moves smoother between the open and closed states.

Benefits of technology

The synchronous movement of the left and right smoke shields is driven by a single power member, the structure is simplified, and the opening and closing efficiency and labor saving of the smoke shields are improved.

Abstract

The utility model relates to a range hood, which comprises: a box body, the bottom wall of which is provided with a smoke inlet; the smoke baffle is arranged at the smoke inlet and can move left and right; the driving mechanism comprises a power piece and a transmission assembly; the transmission assembly comprises a first connecting rod and a second connecting rod, the part, close to the upper end, of the first connecting rod is connected with the box body in the mode of rotating around a first axis extending front and back, the connecting position serves as the rotating center, the lower end of the first connecting rod is rotationally connected with the smoke barrier, and the rotating axis extends front and back; the upper end of the second connecting rod is connected with the box body in a manner of rotating around a second axis extending front and back, the joint is taken as a rotating center, the lower end of the second connecting rod is rotationally connected with the smoke baffle, and the rotating axis extends front and back; the output end of the power piece acts on the upper end of the first connecting rod so as to drive the first connecting rod to rotate leftwards and rightwards around the rotation center of the first connecting rod and drive the second connecting rod to rotate leftwards and rightwards around the rotation center of the second connecting rod. The smoke barrier can be well driven to move left and right.
