Abstract

An exhaust structure of a range hood, wherein the range hood includes: a casing, an exhaust structure, a lighting lamp, an alarm, a screen, and touch buttons arranged on the screen; the exhaust structure includes a casing, a disc body, a first valve Plate, first slide rail, first slide pin, first support rod, contact point, middle seat, pivot point, valve stem, driving pin, second support rod, second slide rail, third slide rail, second slide Pin, second valve plate, handle and driving part; a single lever is used to control multiple valve plates. Applying the slide rail to the drive, while controlling the multi-valve plates with a single rod, it can also realize the sequential control of the opening and closing of the multi-valve plates with a single rod. Consisting of contacts mated with slide pins, closed securely, one-way open. The valve stem and the driving part can move mutually, which improves the operational flexibility.

Description

technical field [0001] The invention relates to the field of kitchen and bathroom, in particular to an exhaust structure of a range hood. Background technique [0002] The existing exhaust structure of range hoods is generally a single-lever control single-valve plate, which is difficult to adapt to complex working conditions when encountering complex requirements. However, one valve stem controls multiple valve plates, which is cumbersome and can only be adapted to symmetrical low-demand conditions. [0003] Existing range hood exhaust structures can generally only be opened or closed once, making it difficult to adapt to complex working conditions. The multi-position control of a valve stem can only adapt to simple working conditions, such as multi-way valves. [0004] The slide rails in the prior art are only used for transmission, not for driving. [0005] The driving structure in the prior art is generally absolutely connected with the valve stem, and cannot move rel...
