Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 2 and 5, a range hood, which is a ceiling range hood, includes a box body 1, and a fan system (not shown) is disposed at an upper portion of an inner side of the box body 1, and the fan system may be a common centrifugal fan.

The box body 1 is of a hollow structure, a first air inlet 11 and a second air inlet 12 are formed in the bottom of the box body 1, the two air inlets are communicated with each other to form an air inlet, and the air inlets can be arranged at left and right intervals. The box 1 has formed the cigarette collecting cavity 13 inside, can hold together the cigarette. The air inlets, the smoke collecting cavity 13 and the fan system are in fluid communication, so that oil smoke below the box body 1 can enter the box body 1 after being sucked from the two air inlets and is finally discharged out of the oil smoke suction machine by the fan system.

The range hood further comprises a first smoke baffle 41 and a second smoke baffle 42, and both the first smoke baffle and the second smoke baffle are preferably flat. The first smoke baffle 41 corresponds to the first air inlet 11, and the second smoke baffle 42 corresponds to the second air inlet 12. When the range hood does not work, the first smoke baffle 41 and the second smoke baffle 42 are located at the first position, at this time, the first smoke baffle 41 closes the first air inlet 11, and the second smoke baffle 42 closes the second air inlet 12. In the inactive closed state, it is preferable that the first smoke barrier 41 does not exceed the left end portion of the case 1, and the second smoke barrier 42 does not exceed the right end portion of the case 1, so as to reduce the occupied space. And the bottom of the box body 1 is a plane at the moment, so that the box body is convenient to clean.

The first smoke baffle 41 and the second smoke baffle 42 can also move horizontally in the left-right direction, therefore, when the range hood works, the first smoke baffle 41 can move horizontally to the left side to open the first air inlet 11, the second smoke baffle 42 can move horizontally to the right side to open the second air inlet 12, see fig. 5 and 6, and the first smoke baffle 41 at least partially exceeds the left end part of the box body 1, the second smoke baffle 42 at least partially exceeds the right end part of the box body 1, the first smoke baffle 41 and the second smoke baffle 42 are in the second position, and the second position is non-fixed and can be adjusted according to the cooking state. Therefore, the first smoke baffle 41 and the second smoke baffle 42 also expand negative pressure areas towards the left and right sides, and the formed larger negative pressure area can reduce the escape of oil smoke.

When there is only one air inlet, the first smoke barrier 41 corresponds to the left area of the air inlet, and the second smoke barrier 42 corresponds to the right area of the air inlet. In the present embodiment, it is preferable that the first air inlet 11 and the second air inlet 12 are symmetrical, and the first smoke barrier 41 and the second smoke barrier 42 are symmetrical, where symmetrical means consistent in shape and size and symmetrically arranged with respect to a center line of the bottom of the cabinet 1 in the left-right direction.

The two smoke baffles can be linked and can also move independently. The motion mechanisms of the two smoke baffles can adopt linear driving modules, such as the combination of a motor gear and a rack, the combination of a motor screw rod and a nut, an electric push rod and the like. And the stroke of the two smoke baffles can be adjusted according to the cooking state.

Referring to fig. 3-4 and 6, in the present embodiment, the two smoke baffles are linked and move in opposite directions. The movement mechanism includes a driving mechanism 71, a transmission mechanism 72, and a guide mechanism 73, wherein the driving mechanism 71 is preferably a motor, the driving mechanism 71 has two output shafts 711, and the driving mechanism 71 can be fixed to the rear side in the case 1 so as to extend in the front-rear direction. The combination of the transmission mechanisms 72 and the guide mechanisms 73 preferably has four sets arranged symmetrically back and forth, wherein two sets of the transmission mechanisms 72 and the guide mechanisms 73 are arranged at the front side in the case 1, and the other two sets of the transmission mechanisms 72 and the guide mechanisms 73 are arranged at the rear side outside the case 1.

Each transmission mechanism 72 includes a gear 721 and a rack 722, and each output shaft 711 passes through a corresponding one of the gears 721 and is fixed so that the gear 721 can be driven to rotate when the drive mechanism 71 is activated, the rotation axis of the gear 721 extends in the front-rear direction, and each rack 722 extends in the left-right direction. The two sets of transmission mechanisms 72 on each side share one gear 721, i.e. one gear 721 meshes with two racks 722 simultaneously, thereby causing the two smoke baffles to move in opposite directions. In order to facilitate the same gear 721 driving the two racks 722 to move left and right, the two racks 722 are oppositely arranged and respectively arranged at the upper end part and the lower end part of the gear 721, the two guide mechanisms 73 on the same side are arranged at intervals up and down, and the gear 721 is located between the two guide mechanisms 73. Here, the two racks 722 are disposed opposite to each other, and there is no requirement for strict positional correspondence, that is, particularly in the closed state, the projections of the two racks 722 on the horizontal plane may only partially overlap.

Each guide mechanism 73 comprises a first slide rail 731 and a second slide rail 732 which are slidably matched with each other, the first slide rail 731 on the same side is fixed with the box body 1 through the fixing plate 74, and the rack 722 is fixed with the second slide rail 732. Thus, when the gear 721 rotates, the rack 722 is moved left and right, and the guide mechanism 73 guides the movement of the rack 722.
