[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] The present invention provides a range hood, such as Figures 1-6As shown, the range hood comprises a baffle assembly 1 and a drive assembly 2. The baffle assembly 1 includes a first baffle 11 and a second baffle 12, which are rotatably connected. The top end of the first baffle 11 is rotatably connected to the open side of the range hood housing 100 via a rotating shaft. The drive assembly 2 includes a first drive device 21 and a second drive device 22. The first drive device 21 is used to drive the first baffle 11 to flip, and the second drive device 22 is used to drive the second baffle 12 to flip. When the range hood is in operation, the first drive device 21 and the second drive device 22 respectively drive the first baffle 11 and the second baffle 12 to flip outward, thereby expanding the smoke-collecting space, providing better smoke blocking and inhalation effects, and reducing obstruction to the user's line of sight. The range hood has a simple overall structure and a small number of components. The first baffle 11 and the second baffle 12 are independently controlled by the first drive device 21 and the second drive device 22, respectively, resulting in high control accuracy, low malfunction, easy repair, and low manufacturing costs.

[0041] Optionally, the baffle assembly 1 further includes a third baffle 13, which is rotatably connected to the bottom of the opening side of the range hood housing 100, and the first driving device 21 can drive the first baffle 11 and the third baffle 13 to flip away from the opening side of the range hood housing 100 at the same time. Figure 2-Figure 6 As shown, the baffle assembly 1 also includes a third baffle 13, which can be specifically a smoke passage plate. A plurality of strip-shaped smoke passage holes are evenly arranged on the third baffle 13 for oil smoke to enter. When the range hood is in working condition, the first driving device 21 can also drive the third baffle 13 to flip outward at the same time. The first baffle 11 and the second baffle 12 form a larger smoke-collecting space, and the third baffle 13 is synchronously flipped outward to block the entrance of the smoke-collecting space, which can not only optimize the air intake duct to facilitate the inhalation of oil smoke and obtain a better inhalation effect, but also effectively prevent foreign matter from being sucked into the interior of the range hood, thereby improving the safety of use.

[0042] Optionally, a first rod 3 is provided at the output end of the first driving device 21 , one end of the first rod 3 is connected to the first baffle 11 , and the other end of the first rod 3 is connected to the third baffle 13 .

[0043] In this embodiment, if Figure 3 and Figure 4 As shown, the first rod 3 is vertically fixedly connected to the output end of the first driving device 21, and one end of the first rod 3 ( Figure 3 The top end of the first rod 3 shown in FIG. 1 is connected to the first baffle 11 through a short connecting rod, and the other end of the first rod 3 ( Figure 3 The bottom end of the first rod 3 is connected to the third baffle 13 via a short connecting rod. When the first driving device 21 is started, as shown in FIG. Figure 4 As shown, the output end of the first driving device 21 pushes the first rod 3 forward, and the first rod 3 pushes the first baffle 11 and the third baffle 13 to flip outward, thereby achieving synchronous flipping of the first baffle 11 and the third baffle 13.

[0044] Specifically, the output end of the second driving device 22 is connected to the second rod 4 , and the second rod 4 is connected to the second baffle 12 .

[0045] In this embodiment, if Figure 5 and Figure 6 As shown, the second driving device 22 is fixedly installed in the range hood housing 100, and its output end is connected to one end of the second rod 4 through a short connecting rod, and the other end of the second rod 4 is connected to the second baffle 12. The second rod 4 is in an arc shape as a whole. Figure 6 As shown, the output end of the second driving device 22 pushes the second rod 4 to move, and the other end of the second rod 4 pushes the second baffle 12 to flip outward at a certain angle, so that the second baffle 12 can be folded relative to the first baffle 11 to form an outward turning angle β, which is beneficial to improving the smoking and smoke-collecting effect of the range hood and reducing obstruction to the user's line of sight.

[0046] Specifically, a through hole 131 is provided on the third baffle 13, and the second rod 4 is passed through the through hole 131. Figure 2 As shown, combined with the reference Figure 6 It can be understood that since the second driving device 22 pushes the second baffle 12 to flip through the second rod 4, there may be some motion interference between the second rod 4 and the third baffle 13. In order to avoid motion interference between the second rod 4 and the third baffle 13 and ensure that the second baffle 12 and the third baffle 13 can flip normally, a through hole 131 is opened on the third baffle 13. The through hole 131 can be passed through by the second rod 4, providing avoidance space for the second rod 4.

[0047] Optionally, when the baffle assembly 1 is flipped into place, the first baffle 11 forms an outward turning angle α with the vertical direction, the second baffle 12 forms an outward turning angle β with the vertical direction, and the third baffle 13 forms an outward turning angle δ with the vertical direction, the outward turning angle α is less than the outward turning angle β, and 0°≤α≤45°, 0°≤β≤90°, and 0°≤δ≤45°.

[0048] In this embodiment, if Figure 5 As shown, the value ranges of the valgus angle α, valgus angle β, and valgus angle δ are preferably: 0°≤α<45°, 0°≤β≤90°, and 0°≤δ≤45°, so that the first baffle 11, the second baffle 12, and the third baffle 13 can all be in the optimal state, while having a strong smoke blocking, smoke collecting, and smoking effect, while also not obstructing the user's line of sight, thereby improving the user experience. It is understood that the value range of the valgus angle β is not limited to 0°-90°. By adjusting the dimensions of various components, such as changing the structural dimensions of the second rod 4, the value range of the valgus angle β can be expanded from 0°-90° to 0°-270°. The design selection is based on actual needs and is not limited to the range shown in this embodiment.

[0049] Optionally, the first driving device 21 and the second driving device 22 include electric push rods.

[0050] In this embodiment, the first drive device 21 and the second drive device 22 may be electric push rod assemblies, which include electric push rod output ends, the electric push rod output end of the first drive device 21 being connected to the first rod 3, and the electric push rod output end of the second drive device 22 being connected to the second rod 4. In addition, the first drive device 21 and the second drive device 22 may be other types of linear drive mechanisms, such as hydraulic push rod transmission, gear rack transmission, etc., including but not limited to the methods used in this embodiment.

[0051] Optionally, the range hood further comprises a flue 101 and an oil collecting box 102. The flue 101 is arranged at the top of the range hood housing 100 and is in communication with the range hood housing 100. A check valve is arranged in the flue 101. The oil collecting box 102 is arranged at the bottom of the range hood housing 100 for collecting oil. Figure 1 and Figure 2 As shown, the multi-baffle linkage range hood also includes a flue 101 and an oil collection box 102. A check valve is provided in the flue 101 to prevent oil smoke from flowing back and affecting the exhaust effect of the range hood. The oil collection box 102 is used to collect oil pollution in a unified manner, making it convenient for users to clean it in time.

[0052] In addition, this embodiment also provides a range hood damper linkage method, which is applied to the above-mentioned range hood. The range hood damper linkage method includes:

[0053] When the range hood is not in operation, Figure 1 As shown, the first baffle 11 and the second baffle 12 are coplanar and cover the opening side of the range hood housing 100 to reduce the space occupied by the range hood and protect the internal structure of the range hood housing 100;

[0054] When the range hood is in operation, Figure 2 As shown, combined with the reference Figure 5 and attached Figure 6 Under the action of the first driving device 21 and the second driving device 22, the first driving device 21 pushes the first baffle 11 to flip and form an outward turning angle α with the vertical direction, and the second driving device 22 pushes the second baffle 12 to flip and form an outward turning angle β with the vertical direction. The outward turning angle α is smaller than the outward turning angle β. The first baffle 11 and the second baffle 12 are in an obtuse angle shape, which expands the smoke-collecting space, and the range hood has better smoke-blocking and smoke-collecting effects, while also reducing the obstruction of the user's line of sight.

[0055] Optionally, the range hood baffle linkage method further includes: when the range hood is in a non-working state, such as Figure 3 As shown, the third baffle 13 is received and abutted against the opening side of the range hood housing 100; when the range hood is in operation, the first driving device 21 simultaneously pushes the third baffle 13 to flip outward, as shown in FIG. Figure 4 As shown, the third baffle 13 forms an outward turning angle δ with the vertical direction, and the smoke is sucked into the range hood housing 100 through the strip smoke inlet hole on the third baffle 13. The third baffle 13 can not only optimize the intake flow path to facilitate the intake of oil smoke, but also make the air inlet closer to the smoke stove, so as to obtain a better intake effect, but also effectively prevent foreign matter from being sucked into the range hood, thereby improving the safety of use.

[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
