Referring to fig. 1 and 5, a side-draft range hood includes a housing 1 and a panel 2 disposed at a front side of the housing 1. The panel 2 is provided with a first air inlet 21 and a second air inlet 22 which are arranged at an interval from top to bottom.

Referring to fig. 2 and 6, a first smoke barrier 3 is rotatably connected to the first air inlet 21. A first bracket 7 is arranged between the first smoke baffle 3 and the first air inlet 21, one end of the first bracket 7 is fixedly connected with one side of the first smoke baffle 3 close to the inner side of the shell 1, and the other end of the first bracket 7 is rotatably connected with the part of the panel 2 above the first air inlet 21.

The second air inlet 22 is rotatably connected with a second smoke baffle 4. A second bracket 8 is arranged between the second smoke baffle 4 and the second air inlet 22, one end of the second bracket 8 is fixedly connected with one side of the second smoke baffle 4 close to the inner side of the shell 1, and the other end is rotatably connected with the part of the panel 2 above the second air inlet 22. Preferably, the first bracket 7 and the second bracket 8 are both hinges.

The side-draft range hood further comprises a link mechanism 5 which is simultaneously connected with the first smoke baffle 3 and the second smoke baffle 4 and can drive the first smoke baffle 3 and the second smoke baffle 4 to be opened or closed simultaneously. A link mechanism 5 is provided in the housing 1, and the link mechanism 5 includes a first link extending in the same direction as the panel 2 and movable in the extending direction, and a second link 51 and a third link 52 provided on the first link. One end of the second connecting rod 51 is rotatably connected with the first connecting rod, and the other end is rotatably connected with one side of the first smoke baffle 3 close to the inner side of the shell 1. One end of the third link 52 is rotatably connected to the first link, and the other end is rotatably connected to one side of the second smoke barrier 4 close to the inner side of the housing 1.

The range hood further comprises a driving device 6 for driving the link mechanism 5 to act, the driving device 6 is an electric push rod capable of moving linearly in the embodiment, and comprises a driving motor 61 and a push rod 62 extending below the motor 61, and the push rod 62 forms the first link.

Referring to fig. 3 to 4 and 7 to 8, the second link 51 can abut against the first bracket 7 in the opened state of the first smoke barrier 3, and a first concave groove 511 which is adapted to the shape of the first bracket 7 and is recessed inward from the surface is formed at the abutting portion of the second link 51 and the first bracket 7.

The third link 52 can abut against the second bracket 8 when the second smoke damper 4 is in an open state, and a second groove 521 which is adapted to the shape of the second bracket 8 and is recessed from the surface in the inward direction is formed at the abutting position of the third link 52 and the second bracket 8.

When the push rod 62 of the driving device 6 moves towards the direction approaching the motor 61, the end portions of the second connecting rod 51 and the third connecting rod 52 connected with the push rod 62 move towards the direction of the motor 61 located above, and the end portions of the second connecting rod 51 and the third connecting rod 52 far away from the push rod 62 move towards the front side of the housing 1, so as to drive the first smoke baffle 3 to rotate and open at the first air inlet 21, and the second smoke baffle 4 to rotate and open at the second air inlet 22, until the first groove 511 of the second connecting rod 51 abuts against the first bracket 7, the second groove 5231 of the third connecting rod 52 abuts against the second bracket 8, and the driving device 6 stops working.
