In a first embodiment of the present disclosure:

as shown in fig. 1 to 4, the range hood mainly includes a housing 1, a lifting device 2, a baffle 3, a linkage assembly 4, a driving device 5, a lifting slide rail assembly 6 and a fan 8. Wherein the lifting device 2 is slidably coupled with the housing 1 in a vertical direction so that the lifting device 2 can approach or depart from a lower cooking top. When the lifting device 2 is close to the cooking bench, the smoking effect of the range hood can be improved. Baffle 3 and 1 pivotal connection of casing, can promote range hood's smoking effect when baffle 3 is opened, can guarantee range hood's outward appearance when baffle 3 is closed. The linkage assembly 4 is used to connect the lifting device 2 and the barrier 3 together so that the lifting device 2 and the barrier 3 can be synchronously operated to be opened or closed simultaneously. The driving device 5 is used for driving the lifting device 2 to move. The lifting slide assembly 6 is used to slidably connect the lifting device 2 and the housing 1 together. The fan 8 is arranged in the shell 1, and the fan 8 can force air to flow from indoor to outdoor when working, so that the effect of sucking oil smoke is realized.

As shown in fig. 1 and 2, the bottom of the housing 1 is provided with an inclined slope (not labeled), the housing 1 is further provided with a panel 11 at the bottom of the inclined slope and a first air inlet 12 at the top of the inclined slope, and the first air inlet 12 is used for guiding oil smoke into the housing 1. The inside of the housing 1 is also provided with a fixing bracket 13 for fixing the linkage assembly 4. The fixing bracket 13 is fixedly connected to the housing 1 or is formed integrally therewith.

With continued reference to fig. 1 and fig. 2, a second air inlet 21 is disposed at the front side of the lifting device 2, and the second air inlet 21 is used for guiding the oil smoke into the lifting device 2 and into the housing 1 through the lifting device 2. As can be seen from the figure, the front side of the lifting device 2 is provided with a side plate having a plurality of through holes, and the second air inlet 21 is formed on the side plate, in other words, the plurality of through holes on the side plate are the second air inlet 21. The top of the lifting device 2 is further provided with a first lug 22, and the first lug 22 is used for connecting the linkage assembly 4. The first lug 22 is fixedly connected to the lifting device 2 or is formed in one piece.

As shown in fig. 2, 4 and 6, the linkage assembly 4 includes a first link 41, a rotating rod 42 and a second link 43, the rotating rod 42 is pivotally connected to the fixed bracket 13 on the housing 1, a first end of the first link 41 is pivotally connected to the first lug 22 on the lifting device 2, a second end of the first link 41 is pivotally connected to a first end of the rotating rod 42, a second end of the rotating rod 42 is pivotally connected to a first end of the second link 43, and a second end of the second link 42 is pivotally connected to the baffle 3.

Wherein, the fixed bracket 13 is arranged to avoid the interference of the rotating rod 42 and the shell 1; similarly, the first lug 22 is provided to avoid interference between the rotating first link 41 and the lifting device 2. Therefore, under the premise of ensuring that the rotating rod 42 does not interfere with the housing 1 and under the premise of ensuring that the first connecting rod 41 does not interfere with the lifting device 2, the skilled person can omit the arrangement of the fixing bracket 13 and the first lug 22 as required.

With continued reference to fig. 2, 4 and 6, the rotating rod 42 is a V-shaped rod-like structure, and the rotating rod 42 is pivotally connected to the fixed bracket 13 on the housing 1 through the bent portion of the V-shape. As can be seen from the figures, the length from the first end of the rotating rod 42 to the bend is greater than the length from the second end of the rotating rod 42 to the bend. That is, the length of the portion of the rotating lever 42 close to the first link 41 is greater than the length of the portion of the rotating lever 42 close to the second link 43. Alternatively, a person skilled in the art can also make the length from the first end of the rotating rod 42 to the bent portion smaller than or equal to the length from the second end of the rotating rod 42 to the bent portion according to actual needs.

And the baffle 3 is flush with the panel 11 on the shell 1, so that the baffle 3 does not appear to be obtrusive, and the overall appearance of the range hood is optimized.

As shown in fig. 6, when the baffle 3 is at a position for opening the first air inlet 12, the included angle between the second connecting rod 43 and the rotating rod 42 is an obtuse angle. And the baffle 3 can rotate to the vertical state, so that the oil smoke can be gathered better by the range hood.

Further, although not explicitly shown in the drawings, in order to make the linkage between the lifting device 2 and the baffle 3 more accurate and reliable, the left and right sides of the housing 1 are respectively provided with a linkage assembly 4.

As shown in fig. 4 to 6, a driving device 5 is disposed between the housing 1 and the lifting device 2, and the driving device 5 is used for driving the lifting device 2 to slide. Specifically, the driving device 5 is an electric push rod, one end of which is fixedly connected with the housing 1, and the other end of which is fixedly connected with the lifting device 2. Alternatively, the driving device 5 may be replaced by any other feasible device, such as a screw-nut pair, an electric cylinder, etc., provided that the lifting device 2 can be driven to slide. Further, in order to make the force applied to the lifting device 2 relatively uniform, the driving device 5 is provided at a position intermediate in the left-right direction of the lifting device 2 in fig. 5.

As shown in fig. 3 to 6, two lifting slide rail assemblies 6 are respectively disposed on the left and right sides of the lifting device 2 in fig. 5. The lifting slide rail assembly 6 comprises a lifting slide rail (not marked in the figure) fixedly connected with the lifting device 2 and a lifting fit slide rail (not marked in the figure) fixedly connected with the housing 1, and the lifting slide rail and the lifting fit slide rail are connected together in a sliding manner, so that the lifting device 2 and the housing 1 are connected together in a sliding manner through the matched lifting slide rail and the lifting fit slide rail.

The operation principle of the range hood of the present embodiment will be briefly explained with reference to fig. 4 and 6.

In the process of opening the first and second intake vents 12 and 21, that is, in the process of moving the lifting device 2 and the barrier 3 from the state shown in fig. 4 to the state shown in fig. 6, the driving device 5 in fig. 4 drives the lifting device 2 to move downward, the moving lifting device 2 forces the rotating lever 42 to rotate counterclockwise through the first connecting rod 41, the rotating lever 42 forces the second connecting rod 42 to move downward, and the moving second connecting rod 42 forces the barrier 3 to rotate counterclockwise from the state shown in fig. 4 to the state shown in fig. 6.

In the process of closing the first and second intake vents 12 and 21, that is, in the process of moving the lifter 2 and the barrier 3 from the state shown in fig. 6 to the state shown in fig. 4, the driving device 5 in fig. 6 drives the lifter 2 to move upward, the moving lifter 2 forces the rotating lever 42 to rotate clockwise by the first link 41, the rotating lever 42 forces the second link 42 to move upward, and the moving second link 42 forces the barrier 3 to rotate clockwise from the state shown in fig. 4 to the state shown in fig. 6.

Based on the foregoing description, it can be understood by those skilled in the art that, in the first embodiment of the present disclosure, by providing the linkage 4 between the lifting device 2 and the baffle 3, the lifting device 2 and the baffle 3 can synchronously act through the linkage 4, and thus simultaneously open the first air inlet 12 and the second air inlet 21, or simultaneously shield the first air inlet 12 and the second air inlet 21. Therefore, the range hood can drive the lifting device 2 and the baffle 3 to act simultaneously only by arranging one driving device 5, and the production cost is reduced.

It should be noted that, when the first air inlet 12 and the second air inlet 21 are blocked, they can be completely closed, that is, the baffle 3 can close the first air inlet 12, and the lifting device 2 can slide upwards to a position where the casing 1 closes the second air inlet 21; or may not be enclosed.

Specifically, as shown in fig. 8 to 11, the baffle slide rail assembly 7 includes a baffle slide rail 71 fixedly connected to the baffle 3 and a baffle mating slide rail 72 fixedly connected to the housing 1, and the baffle slide rail 71 and the baffle mating slide rail 72 are slidably connected together, so that the baffle 3 and the housing 1 are slidably connected together through the matched baffle slide rail 71 and the matched baffle mating slide rail 72.

As shown in fig. 10 and 11, also different from the first embodiment, the baffle 3 in this embodiment is further provided with a second lug 31, so that the baffle 3 is pivotally connected with the second link 43 through the second lug 31 to prevent the second link 43 from interfering with the baffle 3 during the rotation process.

As shown in fig. 7, 9 and 11, when the first air inlet 12 is opened, the baffle 3 slides towards the front upper part of the range hood, so that the baffle 3 does not collide with the head of the user in the sliding process.

As shown in fig. 10, after the first air inlet 12 is closed, the baffle 3 is flush with the panel 11 on the housing 1, so that the baffle 3 does not appear obtrusive, and the overall appearance of the range hood is optimized.
