Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

In the description of the present invention, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the disclosed embodiments of the invention may be oriented in different directions and the directional terms are intended to be illustrative and should not be construed as limiting, such as "upper" and "lower" are not necessarily limited to directions opposite to or coincident with the direction of gravity. Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 and 4, a range hood includes a housing 1 and a panel 2 disposed at a front side of the housing 1, wherein an air inlet 21 is disposed on the panel 2.

The air inlet 21 is provided with a smoke baffle plate component 3 which can be turned open or the air inlet 21. The smoke barrier assembly 3 comprises at least two smoke barriers 31, each smoke barrier 3 is arranged at the air inlet 21 along the longitudinal direction, that is, each smoke barrier 3 is arranged from top to bottom (from bottom to top). The smoke barrier 31 in this embodiment has three pieces. In order to prevent the smoke barrier 31 from blocking the sight of the user in the open state, the length of the smoke barrier 31 in the front-back direction in the open state is short, and the length of the smoke barrier 31 in the front-back direction is gradually shortened from top to bottom (i.e., from top to bottom, the length of the second smoke barrier in the front-back direction is shorter than the length of the first smoke barrier in the front-back direction, and the length of the third smoke barrier in the front-back direction is shorter than the length of the second smoke barrier in the front-back direction).

Referring to fig. 2 to 3 and 5 to 6, the range hood further includes a moving mechanism 5 capable of driving each smoke barrier 31 to move. The moving mechanism 5 includes a rack 51, a transmission gear 52, a rotating shaft 53, and a link 54. The number of the transmission gears 52, the rotating shafts 53 and the connecting rods 54 in the present embodiment is the same as the number of the smoke barrier 31 and is correspondingly arranged (i.e. one transmission gear 52, one rotating shaft 53 and one connecting rod 54 are correspondingly arranged for each smoke barrier 31). The rack 51 is arranged longitudinally on the side of the panel 2 facing the inside of the housing 1 and the rack 51 is longitudinally movable relative to the panel 2. The transmission gear 52 is engaged with the rack 51, the rotating shaft 53 extends in the left-right direction of the panel 2, one end of the rotating shaft 53 is fixedly connected with the center of the transmission gear 52, and the other end is rotatably connected with the panel 2. One end of the connecting rod 54 is connected to one side of the smoke barrier 31 facing the inside of the housing 1 in the closed state, and the other end is fixedly connected to the corresponding rotating shaft 53. The connecting rod 54 and the smoke baffle 31 can be connected by arranging the smoke baffle bracket 4.

The movement mechanism 5 further comprises a drive means 55 for moving the rack 51 longitudinally. The driving device 55 includes a motor 553, an output 551 directly or indirectly driven by the motor 553, and a driving gear 552 rotated by the output 551. The output terminal 551 is shaft-shaped, and the axial direction of the output terminal 551 extends in the left-right direction of the panel 2, and the output terminal 551 is fixedly connected to the center of the drive gear 552. The driving gear 552 is engaged with the rack 51 so as to be capable of moving the rack 51 longitudinally.

The driving device 55 drives the driving gear 552 to drive the rack 51 to move upward, the rack 51 drives each transmission gear 52 to rotate, each transmission gear 52 drives the corresponding rotating shaft 53 to rotate, so that the end part of the corresponding connecting rod 54 far away from the rotating shaft 53 moves toward the front side of the panel 2, and the synchronous opening of each smoke baffle 31 is realized.

The driving device 55 drives the driving gear 552 to drive the rack 51 to move downward, the rack 51 drives each transmission gear 52 to rotate, each transmission gear 52 drives the corresponding rotating shaft 53 to rotate, and the end part of the corresponding connecting rod 54 far away from the rotating shaft 53 moves backward, so that the synchronous closing of each smoke baffle 31 is realized.

Referring to fig. 6 to 7, the moving mechanism 5 in the present embodiment has two, which are respectively provided on the right side of the panel 2 as the driving end and on the left side of the panel 2 as the driven end. When the moving mechanism 5 is used as the driven end, the moving mechanism 5 only needs to include the rotating shaft 53 and the link 54. The movement mechanism 5 adopts gear transmission, so that the movement is more stable.
