Furthermore, the outer side of the range hood shell is provided with a power line.

Furthermore, the surface of the oil filter grid is provided with a groove-shaped oil receiving groove.

Furthermore, the function key display area comprises a display screen and function keys.

Further, the smoking air duct is of a trapezoidal progressive horn-shaped structure.

Compared with the prior art, the beneficial effects of the utility model are that this novel lampblack absorber wind channel has simple structure, and inlet air channel is the horn mouth, presents trapezoidal form, has increased the inlet port face for the air inlet is smooth and easy, and the oil smoke of being convenient for takes out, and advantages such as noise reduction also are fit for using widely simultaneously.

Drawings

FIG. 1 is an overall structure effect diagram of the present invention;

FIG. 2 is an overall sectional structural effect diagram of the present invention;

in the figure: the range hood comprises a range hood shell 1, an oil filter screen 2, a function key display area 3, an air box body 4, a mounting frame 5, a fan 6, a smoke suction air duct 7 and a check valve 8.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

As shown in fig. 1-2, the utility model discloses a range hood air duct, which comprises a range hood shell 1, oil filter grids 2, a function key display area 3, an air box body 4, a mounting rack 5, a fan 6, a smoking air duct 7 and a check valve 8, wherein a stack of oil filter grids 2 are symmetrically arranged on the front end surface of the range hood shell 1; lighting equipment is arranged above the oil filter grid 2; the function key display area 3 is arranged on the front end face of the upper side of the range hood shell 1 and is centered in the center of the front end face of the upper side of the range hood shell 1; the air box body 4 is connected to the center of the top end of the range hood shell 1; the mounting rack 5 is fixedly arranged in the bellows body 4; the fan 6 is fixedly arranged on the mounting frame 5; the smoke absorption air duct 7 is of a horn-shaped structure with a large lower part and a large upper part and a large lower part, the lower end of the smoke absorption air duct is arranged in the range hood shell 1 and is positioned at the two outer sides of the oil filter grid 2, and the upper end of the smoke absorption air duct is arranged at the joint of the air box body 4 and the range hood shell 1; the check valve 8 is fixedly mounted on the mounting frame 5 and is positioned on one side where the fan 6 is communicated with the smoking air channel 7.
