[0053] Embodiment 1

[0054] As Figures 1 to 3As shown in the figure, this embodiment provides an oil fume treatment device 100, which can be an oil fume extractor, an integrated stove, etc. This embodiment takes an oil fume extractor as an example for illustration. The oil fume extractor includes a main chassis 60 and a smoke collecting cavity mechanism 20. The smoke collecting cavity mechanism 20 is arranged at the lower end of the main chassis 60 and is connected to the inside of the main chassis 60. The bottom of the smoke collecting cavity mechanism 20 is provided with a first concave cavity 211 and a second concave cavity 212. The first concave cavity 211 and the second concave cavity 212 are arranged along the left-right direction (i.e., the second direction). A first smoke inlet 2111 is opened on the bottom wall of the first concave cavity 211, and a second smoke inlet 2121 is opened on the bottom wall of the second concave cavity 212. When the main chassis 60 works, the fan inside the main chassis 60 rotates to form a negative pressure area, and the oil fume outside the oil fume extractor can enter the main chassis 60 after passing through the two concave cavities and the two smoke inlets in sequence. The oil fume is filtered inside the main chassis 60 and then discharged to the outside of the main chassis 60.

[0055] As Figures 1 to 3 shown in the figure, the oil fume extractor further includes a smoke baffle assembly. The smoke baffle assembly includes a first smoke baffle 30 and a second smoke baffle 40. Among them, the first smoke baffle 30 corresponds to the first smoke inlet 2111, and the second smoke baffle 40 corresponds to the second smoke inlet 2121.

[0056] As Figure 1 shown in the figure, the oil fume extractor further includes an oil cup 70. The oil cup 70 is arranged at the lower end of the smoke collecting cavity mechanism 20, and the dirty oil inside the smoke collecting cavity mechanism 20 can flow into the oil cup 70 for storage.

[0057] The existing oil fume extractors also include a first driving mechanism and a second driving mechanism. Among them, the first driving mechanism can drive the first smoke baffle 30 to switch between the position of blocking the first smoke inlet 2111 and the position of opening the first smoke inlet 2111. The second driving mechanism can drive the second smoke baffle 40 to switch between the position of blocking the second smoke inlet 2121 and the position of opening the second smoke inlet 2121. The existing oil fume extractors need to set two sets of driving mechanisms, and each set of driving mechanisms drives the first smoke baffle 30 or the second smoke baffle 40 to work separately. The existing oil fume extractors have more driving mechanisms set, and the overall volume of the two sets of driving mechanisms is large, the structure is complex, the energy consumption is high, and the control method is complex.

[0058] To solve the above problems, as Figures 1 to 3As shown, the first smoke baffle 30 is rotatably connected to the smoke collecting chamber mechanism 20 and corresponds to the first smoke inlet 2111, the second smoke baffle 40 is rotatably connected to the smoke collecting chamber mechanism 20 and corresponds to the second smoke inlet 2121, the range hood also includes a driving device 10, the driving device 10 includes a driving mechanism 11 and a transmission assembly 12, the first smoke baffle 30 and the second smoke baffle 40 are respectively connected to the driving mechanism 11 through the transmission assembly 12, so that the first smoke baffle 30 and the second smoke baffle 40 can be flipped synchronously, and only one set of driving device 10 is provided to realize the synchronous flipping of the first smoke baffle 30 and the second smoke baffle 40. Compared with the two sets of driving mechanisms in the prior art, the driving device 10 of the embodiment of the present disclosure has a smaller size, a simpler structure, low energy consumption and a simpler control method.

[0059] In an optional embodiment, if Figure 2 and Figure 3 As shown, the first smoke baffle 30 and the second smoke baffle 40 are symmetrically arranged, and the center line of the driving device 10 and the symmetry line of the first smoke baffle 30 and the second smoke baffle 40 are convenient for the driving device 10 to synchronously drive the first smoke baffle 30 and the second smoke baffle 40, thereby realizing a rational arrangement of the driving device 10, the first smoke baffle 30 and the second smoke baffle 40 in a limited space.

[0060] In an optional embodiment, if Figure 2 and Figure 3 As shown, the driving mechanism 11 includes a first body 111 and a first output end 112 that can move relative to the first body 111 in the up-down direction (i.e., the first direction). The first body 111 is disposed in the smoke collecting chamber mechanism 20. The first output end 112 is respectively connected to the first smoke baffle 30 and the second smoke baffle 40 through the transmission assembly 12. The first smoke baffle 30 and the second smoke baffle 40 can be synchronously flipped by the simple linear motion of the first output end 112 relative to the first body 111. The driving mechanism 11 has a simple structure and is easy to install. Specifically, the driving mechanism 11 can be a linear output driving mechanism, which can be a linear output motor, a linear output cylinder, a linear guide rail, etc. It can also be a motor with a gear rack assembly, a motor with a multi-link assembly, a motor with a crank slider structure, etc. All structures or components that can achieve linear motion output are within the protection scope of this optional embodiment.

[0061] In an optional embodiment, if Figure 2 and Figure 3As shown, the transmission assembly 12 includes a mounting member 121, a first connecting rod 122, and a second connecting rod 123. The mounting member 121 is fixedly connected to the first output end 112. One end of the first connecting rod 122 is rotatably connected to the mounting member 121, and the other end of the first connecting rod 122 is rotatably connected to the first smoke baffle 30. One end of the second connecting rod 123 is rotatably connected to the mounting member 121, and the other end of the second connecting rod 123 is rotatably connected to the second smoke baffle 40.

[0062] If the setting position of the first output end 112 is at the upper end of the first body 111, when the first output end 112 is at a low position, the first smoke baffle 30 opens the first smoke inlet 2111. When the first output end 112 is at a high position, the second smoke baffle 40 opens the second smoke inlet 2121. When the first output end 112 moves upward, that is, from Figure 2 state to Figure 3 state, the first output end 112 simultaneously drives the first hinge point of the first connecting rod 122 and the second hinge point of the second connecting rod 123 to move upward at the same time. The first connecting rod 122 and the second connecting rod 123 rotate around their respective hinge points, and the first connecting rod 122 and the second connecting rod 123 rotate in a trend of approaching each other. At the same time, the first connecting rod 122 drives the first smoke baffle 30 to rotate clockwise so that the first smoke baffle 30 closes and seals the first smoke inlet 2111, and the second connecting rod 123 drives the second smoke baffle 40 to rotate counterclockwise so that the second smoke baffle 40 closes and seals the second smoke inlet 2121. Through the up-and-down movement of the first output end 112, the first smoke inlet 2111 and the second smoke inlet 2121 are synchronously opened or blocked. By adjusting the position and stroke of the first output end 112, the opening and closing angles of the first smoke baffle 30 and the second smoke baffle 40 can be adjusted, so as to realize the adjustment of the air intake volume of the first smoke inlet 2111 and the second smoke inlet 2121. In an alternative embodiment, the first output end 112 can also be arranged at the lower end of the first body 111, and the above technical effects can also be achieved.

[0063] In an alternative embodiment, as Figure 2 and Figure 3 shown, the range hood further includes a guiding mechanism 50. The guiding mechanism 50 is arranged between the mounting member 121 and the smoke collecting cavity mechanism 20. The guiding mechanism 50 is used to make the mounting member 121 move in the up-and-down direction without deviation, so as to realize the precise drive of the first smoke baffle 30 and the second smoke baffle 40.

[0064] In an alternative embodiment, as Figure 2 and Figure 3As shown, the guiding mechanism 50 includes a guide rail 51 and a third slider 52. The guide rail 51 extends in the up and down direction and is fixedly connected to the smoke collecting chamber mechanism 20. The third slider 52 is fixedly connected to the mounting member 121 and can slide along the guide rail 51. Through the cooperation of the guide rail 51 and the third slider 52, an accurate guiding effect for the up and down movement of the mounting member 121 can be achieved.

[0065] In an alternative embodiment, at least two guiding mechanisms 50 are provided. Two of the guiding mechanisms 50 are arranged in the front and back direction (i.e., the third direction). By providing at least two guiding mechanisms 50, rotation of the mounting member 121 during the up and down movement can be avoided.

[0066] In an alternative embodiment, as Figure 2 and Figure 3 shown, the smoke collecting chamber mechanism 20 includes a smoke collecting hood 21 and a mounting base 22. A first smoke inlet 2111 and a second smoke inlet 2121 are formed on the smoke collecting hood 21. The mounting base 22 is disposed on the smoke collecting hood 21, the first body 111 is disposed on the mounting base 22, and both the first smoke baffle 30 and the second smoke baffle 40 are rotatably connected to the mounting base 22. The strength and hardness of the mounting base 22 are relatively large, and the mounting base 22 can stably support the driving device 10, the first smoke baffle 30, and the second smoke baffle 40.

[0067] Since the smoke collecting hood 21 is very thin, it is not easy to place a relatively large driving mechanism 11 inside the smoke collecting hood 21. In an alternative embodiment, as Figure 2 and Figure 3 shown, the driving mechanism 11 is located between the first smoke inlet 2111 and the second smoke inlet 2121, and at least part of the driving mechanism 11 is located in the main cabinet 60. The space at the connection position between the main cabinet 60 and the smoke collecting hood 21 is reasonably utilized to effectively accommodate the driving mechanism 11, and the main cabinet 60 can completely shield the driving mechanism 11, making the overall shape of the range hood more beautiful.

[0068] In an alternative embodiment, of course, part of the driving mechanism 11 or all of the driving device 10 can also be arranged outside the main cabinet 60, which is convenient for users to check and maintain the state of the driving mechanism 11.

[0069] Embodiment Two

[0070] The present disclosure embodiment discloses an oil fume treatment device 100. The structure of the oil fume treatment device 100 is basically the same as that of the oil fume treatment device 100 in Embodiment One. The main difference between the two is that as Figure 4 and Figure 5As shown in the figure, the structure of the transmission assembly 12 is different. Specifically, the transmission assembly 12 includes a mounting member 121, a connecting member 124, a first connecting rod 122, a first slider 125, a second connecting rod 123, and a second slider 126. The mounting member 121 is fixedly connected to the smoke collecting chamber mechanism 20, the connecting member 124 is fixedly connected to the first output end 112. One end of the first connecting rod 122 is rotatably connected to the first slider 125. The first slider 125 can slide relative to the connecting member 124 in the second direction. The other end of the first connecting rod 122 is fixedly connected to the first smoke baffle 30. The middle part of the first connecting rod 122 is rotatably connected to the mounting member 121. One end of the second connecting rod 123 is rotatably connected to the second slider 126. The second slider 126 can slide relative to the connecting member 124 in the second direction. The other end of the second connecting rod 123 is fixedly connected to the second smoke baffle 40. The middle part of the second connecting rod 123 is rotatably connected to the smoke collecting chamber mechanism 20. Through this transmission assembly 12, it is also possible to achieve the synchronous flipping of the first smoke baffle 30 and the second smoke baffle 40 by only setting one set of driving devices 10. Compared with the two sets of driving mechanisms in the prior art, the driving device 10 in the embodiment of the present disclosure has a smaller volume, a simpler structure, lower energy consumption, and a simpler control method.

[0071] Specifically, as Figure 4 and Figure 5 shown, the connecting member 124 includes a connecting member body 1241 and a slide rail 1242 which are fixedly connected. The connecting member body 1241 is fixedly connected to the first output end 112. The slide rail 1242 extends in the left-right direction. The first slider 125 and the second slider 126 are arranged on the slide rail 1242 and can slide along the slide rail 1242. The slide rail 1242 can achieve a good guiding effect on the first slider 125 and the second slider 126.

[0072] Embodiment Three

[0073] The embodiment of the present disclosure discloses an oil fume treatment device 100. The structure of the oil fume treatment device 100 is basically the same as that of the oil fume treatment device 100 in Embodiment One. The main difference between the two is that as Figure 6As shown in the figure, the structure of the transmission component 12 is different. Specifically, the driving mechanism 11 is a motor, which includes a second body 113 and a second output end 114 that can rotate relative to it. The transmission component 12 includes a first gear 127 and a second gear 128 that mesh with each other. The first smoke baffle 30 includes a first rotating shaft 31 and a first baffle body 32 that are fixedly connected. The first rotating shaft 31 is rotatably connected to the smoke collecting cavity mechanism 20. The second smoke baffle 40 includes a second rotating shaft 41 and a second baffle body 42 that are fixedly connected. The second rotating shaft 41 is rotatably connected to the smoke collecting cavity mechanism 20. The first gear 127 is coaxially fixed to the first rotating shaft 31, and the second gear 128 is coaxially fixed to the second rotating shaft 41. The first rotating shaft 31 is coaxially fixed to the second output end 114. When the motor works, the second output end 114 drives the first rotating shaft 31 and the first baffle body 32 to rotate. Under the transmission of the first gear 127 and the second gear 128, the second rotating shaft 41 and the second baffle body 42 can be synchronously flipped. The first gear 127 and the second gear 128 have high reliability in cooperation, large load-bearing capacity, long service life and strong adaptability.

[0074] In an alternative embodiment, it can also be that the second output end 114 is coaxially fixed to the second rotating shaft 41, and the above effect can also be achieved.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
