AI Technical Summary

Technical Problem

In the existing technology, the connection method of the smoke baffle movement mechanism is complicated, resulting in low driving force transmission efficiency and insufficient stability of the smoke baffle during movement, making it easy to collide with the outer panel of the range hood.

Method used

The design employs a sleeve and an inner push rod, with the inner push rod fitted inside the sleeve. The inner push rod is driven by a motor to move within the sleeve, thereby driving the driven mechanism to stably open or close the smoke baffle. Combined with a coupling and hinge structure, this ensures the consistency and stability of the movement.

Benefits of technology

This improves the stability of the smoke baffle, prevents it from colliding with the outer panel of the range hood, and enhances the service life of the smoke baffle and the user experience.

Abstract

The present disclosure relates to a smoke baffle movement mechanism and a range hood, the smoke baffle movement mechanism comprising: a first fixing member, a driving mechanism, and a driven mechanism, the first fixing member being fixed to a first side wall of the range hood; the driving mechanism comprising a sleeve and an inner push rod, the inner push rod being sleeved in the sleeve, one end of the inner push rod extending out of the sleeve; the sleeve being connected with the first fixing member, the end of the inner push rod extending out of the sleeve being movably connected with one end of the driven mechanism; the other end of the driven mechanism being movably connected with an inner wall of the smoke baffle, the driven mechanism being used to move the smoke baffle under the driving of the inner push rod. The present disclosure can more conveniently realize the opening or closing of the smoke baffle by the movement of the inner push rod sleeved in the driving mechanism and the driven mechanism connected therewith, makes the movement process of the smoke baffle more stable, and prevents collision.
