Problems solved by technology

[0003] Although the existing range hood can greatly improve the range hood effect by setting the lifting mechanism to drive the smoke deflector to move up and down, the main problem is that the lifting mechanism will produce vibration and abnormal sound during the movement, and the user experience needs to be improved. In addition, the lifting mechanism will produce an unstable phenomenon of "weight loss" due to its own weight during the descent process, which will affect the structural stability of the lifting mechanism.

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the lifting mechanism of the smoke guide plate of the range hood in this embodiment includes a mounting frame 1 , an electric push rod device 2 , a lifting connection device 3 and a smoke guide plate 4 . Among them, the electric push rod device 2 is installed on the installation frame 1, the lifting connection device 3 is installed on the output end of the electric push rod device 2, and the smoke guide plate 4 is installed on the bottom of the lifting connection device 3, on both sides of the installation frame 1 Each is provided with a counterweight device used to counteract the influence of the load gravity of the lifting mechanism.

[0017] In this embodiment, the counterweight device adopts a counterweight 5, and the counterweight 5 is connected to the lifting connection device 3 through a connecting rop...

Abstract

The invention discloses a smoke deflector lifting mechanism for an extractor hood. The smoke deflector lifting mechanism comprises an installation frame, an electric push rod device, a lifting connection device and a smoke deflector, wherein the electric push rod device is arranged on the installation frame; the lifting connection device is arranged at an output end of the electric push rod device; and the smoke deflector is arranged at the bottom of the lifting connection device. The smoke deflector lifting mechanism is characterized in that counterweight devices for counteracting the influence of load gravity of the lifting mechanism are arranged at two sides of the installation frame. The smoke deflector lifting mechanism has the advantages that the counterweight devices for counteracting the influence of load gravity of the lifting mechanism are arranged at two sides of the installation frame, and the lifting mechanism is capable of counteracting the influence of the load gravity when the lifting mechanism moves up and down, so that 'zero load' is achieved, stress is uniform, the power of a drive motor is reduced, the lifting mechanism is not in a 'gravity-free' condition especially when moving downwards, smooth motion is kept, noise and abnormal noise are not generated, and furthermore, the lifting mechanism has the same ascending and descending speeds.

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 in the Chinese utility model patent whose patent number is 201620042811.2 (authorized announcement number is CN 205372692U), the range hood includes a smoke guide plate and a fixed plate, and one side of the fixed plate There is a fixed guide rail, and a matching moving guide rail is provided inside the fixed guide rail. A transmission rod is arranged beside the fixed guide rail. The transmission rod is offset against the moving guide rail. There is a fixed bracket at the lower end of the guide rail, and the fixed bracket is offset again...
