Rotating mechanism of range hood smoke baffle

Abstract

The invention relates to a rotating mechanism of a range hood smoke baffle. The rotating mechanism comprises a base, a swinging component, a driving assembly and a torsional spring. The base is fixedly mounted on a shell of a range hood. The swinging component is fixedly connected with a smoke baffle, and is rotatably connected with the base by a first rotating shaft. The driving assembly comprises a first connecting arm and a second connecting arm which are rotatably connected. Two ends of the torsional spring are separately connected with the first connecting arm and the second connecting arm. The first connecting arm is connected with the swinging component. The second connecting arm is rotatably connected with the base by a second rotating shaft. When the smoke baffle opens or closes part of the angle, the swinging component drives the first connecting arm to move, and therefore the first connecting arm and the second connecting arm rotate relatively, the connecting inflection point between the first connecting arm and the second connecting arm is on the plane formed by axes of the first rotating shaft and the second rotating shaft. The rotating mechanism of the range hood smoke baffle enables the smoke baffle to continue to open or close after part of the angle is opened or closed by the smoke baffle and manually. Application is convenient and labor-saving.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a rotating mechanism for a smoke baffle of a range hood. Background technique [0002] The oblique or side suction range hoods currently on the market have greatly improved the absorption rate of the oil fume with their low-position smoking, and because they are installed against the wall, the oil fume enters the range hood from an oblique direction, which avoids The operator passively inhales the fume, and overcomes the shortcomings of the traditional top suction range hood. The smoke baffle of the near-suction range hood, because it can block the oil fume in the open state, forms a negative pressure smoke collection area with the body, and can prevent the internal odor diffusion of the range hood in the closed state, reducing the oil fume pouring from the public flue. Channeling and other issues. [0003] In the prior art, the opening or closing of the smoke baffle is mai...

AI Technical Summary

Problems solved by technology

It can be seen that the user needs continuous force during the turning process of the smoke baffle, and without the use of external force, the smoke baffle cannot be closed tightly, which affects the overall performance and experience of the range hood
