[0055] Embodiment 1

[0056] As Figures 1 to 4 shown, this embodiment provides an oil fume treatment device 100. The oil fume treatment device 100 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 cabinet 60 and a smoke collecting cavity mechanism 20. The smoke collecting cavity mechanism 20 is arranged at the lower end of the main cabinet 60 and is in communication with the interior of the main cabinet 60. As Figure 1 and Figure 2 shown, the smoke collecting cavity mechanism 20 includes a smoke collecting hood 21. The smoke collecting hood 21 includes a bottom plate 211, a front side plate assembly 212, a rear side plate assembly 213, a left side plate 214, a right side plate 215, and an upper end plate 216. The front side plate assembly 212, the left side plate 214, the rear side plate assembly 213, and the right side plate 215 are connected in sequence. The front side plate assembly 212 and the rear side plate assembly 213 are arranged at intervals in the front-rear direction, and the left side plate 214 and the right side plate 215 are arranged in the left-right direction. The front side plate assembly 212, the left side plate 214, the rear side plate assembly 213, and the right side plate 215 together form a cavity space. The cavity space includes an upper opening and a lower opening. The upper end plate 216 is located at the upper opening, and the bottom plate 211 is located at the lower opening.

[0057] In an alternative embodiment, as Figure 2 shown, the smoke collecting cavity mechanism 20 further includes a support frame 22. The support frame 22 is arranged inside the smoke collecting hood 21 and is fixedly connected to the smoke collecting hood 21. By providing the support frame 22, the strength and hardness of the smoke collecting cavity mechanism 20 can be effectively improved. As Figure 2 shown, the support frame 22 includes one, two, or more support frames 22. One end of the support frame 22 is fixedly connected to the front side plate assembly 212, and the other end of the support frame 22 is fixedly connected to the rear side plate assembly 213. By providing a plurality of support frames 22, on the premise of saving space, the strength and hardness of the smoke collecting cavity mechanism 20 can be significantly improved. In addition, the structure of the support frame 22 is simple, which is convenient to achieve a quick and stable connection effect between the support frame 22 and the smoke collecting cavity mechanism 20. It should be noted that the support frame 22 can be fixedly connected to at least one of the front side plate assembly 212, the rear side plate assembly 213, the upper end plate 216, and the bottom plate 211, and can also significantly improve the strength and hardness of the smoke collecting cavity mechanism 20.

[0058] As shown Figures 2 to 4 in FIG. Figures 2 to 4 , the range hood further includes a mounting mechanism 80. The mounting mechanism 80 is fixedly connected to the smoke collecting cavity mechanism 20. The driving device 10 is disposed on the mounting mechanism 80. On the one hand, the mounting mechanism 80 can be well connected to the smoke collecting cavity mechanism 20. On the other hand, the mounting mechanism 80 can also well support the driving device 10. Through the arrangement of the mounting mechanism 80, it is convenient for the driving device 10 to be well installed and connected to the smoke collecting cavity mechanism 20.

[0059] In an alternative embodiment, as shown Figure 3 in FIG. Figure 3 , the front side plate assembly 212 includes a front side plate 2121 and a first reinforcing member 2122. Among them, the front side plate 2121, the left side plate 214, the rear side plate assembly 213 and the right side plate 215 are fixedly connected in sequence. The first reinforcing member 2122 is disposed on the inner side of the front side plate 2121. Through the arrangement of the first reinforcing member 2122, the strength and hardness of the front side plate assembly 212 are improved to realize the stable support for the support frame 22, the mounting mechanism 80, the main chassis 60 and the driving device 10.

[0060] In an alternative embodiment, as shown Figure 2 in FIGS. Figure 4 and Figure 5 Figure 5 , the rear side plate assembly 213 includes a rear side plate 2131 and a second reinforcing member 2132 disposed thereon. The support frame 22 is fixedly connected to the second reinforcing member 2132. Through the arrangement of the second reinforcing member 2132, the strength and hardness of the rear side plate assembly 213 are improved to realize the stable support for the support frame 22, the mounting mechanism 80, the main chassis 60 and the driving device 10.

[0061] In an alternative embodiment, the bottom plate 211, the left side plate 214, the right side plate 215, the upper end plate 216, etc. can also adopt a similar structure to the aforementioned front side plate assembly 212 or rear side plate assembly 213, and can also achieve the effect of further strengthening the stable support of the smoke collecting cavity mechanism 20 for the driving device 10 and the main chassis 60.

[0062] As shown Figure 1 in FIGS. Figure 2 Figure 2 , the bottom plate 211 is provided with a first concave cavity 2111 and a second concave cavity 2112. The first concave cavity 2111 and the second concave cavity 2112 are arranged in the left-right direction. The bottom wall of the first concave cavity 2111 is provided with a first smoke inlet 21111, and the bottom wall of the second concave cavity 2112 is provided with a second smoke inlet 21121. When the main chassis 60 works, the fan inside the main chassis 60 rotates to form a negative pressure area. The oil fume outside the range hood 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 in the main chassis 60 and then discharged to the outside of the main chassis 60.

[0063] In an alternative embodiment, it is also possible that only one first concave cavity 2111 is provided on the bottom plate 211. In an alternative embodiment, three, four or more smoke inlets may also be provided on the bottom plate 211.

[0064] As Figure 1 and Figure 2 shown, the range hood further includes a smoke baffle assembly, and 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 21111, and the second smoke baffle 40 corresponds to the second smoke inlet 21121. The first smoke baffle 30 can be selectively switched between a first position where the first smoke inlet 21111 is opened and a second position where the first smoke inlet 21111 is blocked. The second smoke baffle 40 is switched between a third position where the second smoke inlet 21121 is opened and a fourth position where the second smoke inlet 21121 is blocked. The open or blocked states of the first smoke inlet 21111 and the second smoke inlet 21121 can be adaptively adjusted according to the specific situation of the oil fume. It should be noted that the smoke baffle assembly may also include only one smoke baffle, or may also include three, four or more smoke baffles.

[0065] In an alternative embodiment, as Figure 1 shown, the range hood further includes an oil cup 70, and the oil cup 70 is arranged at the lower end of the smoke collecting cavity mechanism 20. The dirty oil inside the smoke collecting cavity mechanism 20 can flow into the oil cup 70 for storage.

[0066] As Figures 2 to 4 shown, the range hood further includes a driving device 10, and the driving device 10 is used to make the first smoke baffle 30 and the second smoke baffle 40 move synchronously, so that each smoke baffle is switched between a position where the corresponding smoke inlet is blocked and a position where the corresponding smoke inlet is opened.

[0067] In the existing one, since the main chassis 60 includes an air duct, an impeller and a motor, the total weight of the main chassis 60 is relatively heavy, and there is a risk of vertical drop during the transportation of the main chassis 60. In the existing one, the main chassis 60 is arranged at the upper end of the smoke collecting cavity mechanism 20 and fixedly connected to the upper end plate 216. The connection between the main chassis 60 and the smoke collecting cavity mechanism 20 is relatively weak. When the range hood is subjected to a vertical impact, the smoke collecting cavity mechanism 20 is easily deformed and damaged.

[0068] To solve the above problems, in combination with Figures 1 to 6As shown, the main cabinet 60 with a relatively heavy total weight is fixedly connected to the smoke collecting hood 21, the support frame 22, and the installation mechanism 80 respectively. Through the above connection method, the weight of the main cabinet 60 can be relatively dispersed to different positions of the smoke collecting hood 21, the support frame 22, and the installation mechanism 80. For the relatively large weight of the main cabinet 60, a better dispersion effect can be obtained. Different positions of the smoke collecting hood 21, the support frame 22, and the installation mechanism 80 can jointly provide a better support effect for the relatively heavy main cabinet 60. Even if the range hood is vertically impacted, the smoke collecting cavity mechanism 20 will not be deformed or damaged, ensuring that the smoke collecting cavity mechanism 20 always has a better shape and usage effect.

[0069] In an alternative embodiment, as Figures 2 to 4 shown, the installation mechanism 80 can be fixedly connected to the front side plate assembly 212, the rear side plate assembly 213, and the support frame 22 respectively. Since different positions of the smoke collecting cavity mechanism 20 are fixedly connected to the installation mechanism 80, a better stable support effect of the smoke collecting cavity mechanism 20 on the installation mechanism 80 and the driving device 10 can be achieved.

[0070] In an alternative embodiment, as Figure 6 shown, the first reinforcing member 2122 further includes a fourth flanging 21221. The installation mechanism 80 abuts against and is fixed to the fourth flanging 21221, thereby realizing the stable connection between the front side plate assembly 212 and the installation mechanism 80.

[0071] In an alternative embodiment, the installation mechanism 80 can also be fixedly connected to at least one of the front side plate assembly 212, the rear side plate assembly 213, and the support frame 22, and a better connection and fixing effect between the installation mechanism 80 and the smoke collecting cavity mechanism 20 can also be achieved. It should be noted that the installation mechanism 80 can be fixedly connected to at least one of the front side plate assembly 212, the rear side plate assembly 213, the upper end plate 216, the bottom plate 211, and the support frame 22. The more relevant structures the installation mechanism 80 is connected to, the better the dispersion effect of the weight of the driving device 10 and the main cabinet 60 can be achieved, and the deformation risk of the smoke collecting cavity mechanism 20 can be effectively reduced.

[0072] In an alternative embodiment, as Figure 5 and Figure 6 shown, the main cabinet 60 is fixedly connected to the support frame 22, the upper end plate 216, the rear side plate assembly 213, and the installation mechanism 80. The weight of the main cabinet 60 can be dispersed to the front side plate assembly 212, the rear side plate assembly 213, the upper end plate 216, the bottom plate 211, the support frame 22, and the installation mechanism 80. Each part of the smoke collecting cavity mechanism 20 is subjected to relatively small forces, and there will be no problem of concentrated stress on each part of the smoke collecting cavity mechanism 20, thereby effectively reducing the deformation risk of the smoke collecting cavity mechanism 20.

[0073] In an alternative embodiment, as Figure 5 shown, the support frame 22 includes a first support beam 222 and a second support beam 223 arranged at intervals in the left - right direction. The first support beam 222 includes a first support beam body 2222 and a first flange 2221 fixedly connected. The first support beam body 2222 is fixedly connected to the smoke collecting hood 21, and the first flange 2221 abuts against and is fixedly connected to the left side wall 61 of the main chassis 60, thereby realizing a firm connection between the first support beam 222 and the main chassis 60.

[0074] In an alternative embodiment, as Figure 5 shown, the second support beam 223 includes a second support beam body 2232 and a second flange 2231 fixedly connected. The second flange 2231 abuts against and is fixedly connected to the right side wall 62 of the main chassis 60, thereby realizing a firm connection between the second support beam 223 and the main chassis 60.

[0075] In summary, through the combined cooperation of the first support beam 222 and the second support beam 223, the first support beam 222 and the second support beam 223 can jointly support the main chassis 60 in the left - right direction of the main chassis 60, thereby realizing the firm support of the support frame 22 for the main chassis 60.

[0076] As Figure 6 shown, the upper region of the rear side plate assembly 213 protrudes toward the rear of the rear side plate assembly 213 to form a plug - in groove 21311. The rear side wall 63 of the main chassis 60 is plugged into the plug - in groove 21311 and fixedly connected to the upper region of the rear side plate assembly 213, which can realize the quick positioning and assembly effect of the rear side plate assembly 213 and the main chassis 60.

[0077] As Figure 6 shown, the upper end plate 216 includes an upper end plate body 2161 and a third flange 2162. An insertion opening 21611 is formed on the upper end plate body 2161, and the third flange 2162 extends from the insertion opening 21611. The main chassis 60 is plugged into the insertion opening 21611, and the third flange 2162 abuts against and is fixed to the front side wall 64 of the main chassis 60, which can realize the firm connection between the upper end plate 216 and the main chassis 60. In other alternative embodiments, the third flange 2162 can also abut against and be fixedly connected to the left side wall 61, the right side wall 62 or the rear side wall 63.

[0078] In an alternative embodiment, as Figure 3 、 Figure 4 and Figure 7As shown, the installation mechanism 80 includes a plurality of connecting beams 811. The plurality of connecting beams 811 together form an accommodation space 84. At least part of the driving device 10 is accommodated in the accommodation space 84. While ensuring good strength of the installation mechanism 80, it can also achieve a compact arrangement of the installation mechanism 80 and the driving device 10, and can reasonably place the installation mechanism 80 and the driving device 10 in the limited space within the smoke collecting hood 21, realizing the rational use of the limited space.

[0079] It should be noted that two adjacent connecting beams 811 can be fixed in various ways such as welding, pin fixing, screw fixing, and snap fixing, all of which can achieve the stable connection of two adjacent connecting beams 811. In an alternative embodiment, the plurality of connecting beams 811 can be formed by bending a whole cross beam. The structure is simple and easy to manufacture. The connecting position of two adjacent connecting beams 811 can undergo plastic deformation to produce a work hardening effect, which can further improve the strength and hardness of the installation mechanism 80.

[0080] In an alternative embodiment, as Figure 7 shown, the connecting beam 811 includes a connecting plate 8111 and a reinforcing plate 8112. The reinforcing plate 8112 extends from one side of the connecting plate 8111. The connecting plate 8111 and the reinforcing plate 8112 are arranged at an angle. Through the setting of the reinforcing plate 8112, the strength and hardness of the connecting beam 811 can be effectively improved, thereby effectively improving the strength and hardness of the installation mechanism 80, and realizing the stable supporting effect of the installation mechanism 80 on the driving device 10. It should be noted that the reinforcing plate 8112 and the connecting plate 8111 can be formed by bending a whole plate, which is convenient for realizing the rapid manufacturing of the connecting beam 811. Due to being processed and manufactured by the bending process, the connecting position of the reinforcing plate 8112 and the connecting plate 8111 can undergo plastic deformation to produce a work hardening effect, which can further improve the strength and hardness of the connecting beam 811 and the installation mechanism 80.

[0081] In an alternative embodiment, the connecting plate 8111 and the reinforcing plate 8112 can be fixed well by means such as welding, screw fixing, pin fixing, and snap component fixing.

[0082] Combined with Figures 2 to 4 、 Figure 8 and Figure 9 shown, the driving device 10 includes at least two driving mechanisms 11. Each driving mechanism 11 can independently drive the corresponding smoke baffle, and each smoke baffle is independently controlled by the corresponding driving mechanism 11, enabling flexible control of each smoke baffle.

[0083] In an alternative embodiment, combined with Figures 2 to 4 and Figure 7As shown, the driving mechanism 11 includes a first body 115 and a first output end 116 that can move linearly relative to the first body 115. The first body 115 can be pivotally connected to the mounting mechanism 80 about the front-rear direction. The first output end 116 is fixedly connected to the first smoke baffle 30. The first smoke baffle 30 includes a first baffle body 32 and a first rotating shaft 31 provided thereon. The first rotating shaft 31 extends along the front-rear direction. A guiding groove 831 is formed in the mounting mechanism 80. The first rotating shaft 31 is inserted into the guiding groove 831, and the extending direction of the guiding groove 831 is perpendicular to the front-rear direction. When the first output end 116 moves linearly relative to the first body 115, the first output end 116 drives the first rotating shaft 31 to slide along the guiding groove 831, and the first body 115 rotates relative to the mounting mechanism 80 about the front-rear direction, thereby realizing the complex curvilinear motion path of rotation and movement of the first baffle body 32 relative to the smoke collecting hood 21. When the first smoke baffle 30 is in the state of opening the first smoke inlet 21111, the outer contour edges of the first smoke baffle 30 are all spaced from the smoke collecting hood 21. That is to say, smoke can enter from all circumferential directions of the first smoke baffle 30, and the smoke extraction effect of the range hood can be further improved compared with the first baffle body 32 that can only perform a single flipping motion.

[0084] In an alternative embodiment, as Figure 4 and Figure 7 shown, the mounting mechanism 80 includes a mounting main body 81 and a first mounting plate 82. The mounting main body 81 is fixedly connected to the smoke collecting cavity mechanism 20. The first mounting plate 82 is arranged on the mounting main body 81. The first body 115 is pivotally connected to the first mounting plate 82. Through the arrangement of the first mounting plate 82, the quick assembly of the first body 115 and the mounting mechanism 80 is facilitated. Exemplarily, the first body 115 can be connected to the first mounting plate 82 through a pivot shaft, wherein the pivot shaft extends along the front-rear direction.

[0085] In an alternative embodiment, as Figure 4 and Figure 7 shown, the mounting mechanism 80 further includes a second mounting plate 83. The second mounting plate 83 is arranged on the mounting main body 81. The guiding groove 831 is formed in the second mounting plate 83. Through the arrangement of the second mounting plate 83, the quick assembly of the first rotating shaft 31 and the guiding groove 831 is facilitated. Exemplarily, the second mounting plate 83 can be provided as one, two, three or more. When the second mounting plate 83 is one, the overall structure of the range hood is simple; when the second mounting plate 83 is at least two, at least two second mounting plates 83 are arranged at intervals along the front-rear direction, and at least two second mounting plates 83 jointly support the first rotating shaft 31, and at least two second mounting plates 83 can achieve a relatively stable supporting effect on the first rotating shaft 31.

[0086] In an alternative embodiment, the structure of the second smoke baffle 40 is the same as or similar to that of the first smoke baffle 30, and the connection manner between the second smoke baffle 40 and the mounting mechanism 80 is the same as or similar to that between the first smoke baffle 30 and the mounting mechanism 80.

[0087] In an alternative embodiment, as Figure 4 shown, the first smoke baffle 30 may further include a support plate 33. The support plate 33 is disposed on the first baffle body 32, and the first output end 116 is fixedly connected to the support plate 33, facilitating the quick and stable assembly of the first output end 116 and the support plate 33.

[0088] In an alternative embodiment, the drive mechanism 11 includes a first body 115 and an output end capable of moving linearly relative to the first body 115. The first body 115 is pivotally connected to the mounting mechanism 80 about the front-rear direction (i.e., the extending direction of the first axis), the output end is pivotally connected to the first smoke baffle 30 about the front-rear direction (i.e., the extending direction of the second axis), and the first smoke baffle 30 is pivotally connected to the smoke collecting cavity mechanism 20 about the front-rear direction (i.e., the extending direction of the third axis). When the output end moves linearly relative to the first body 115, the first body 115 can rotate relative to the mounting mechanism 80, and the output end can push the first smoke baffle 30 to rotate relative to the mounting mechanism 80 about the front-rear direction, thereby realizing the position switching of the drive mechanism 11 for the first smoke baffle 30. The connection manner between the drive mechanism 11 and the first smoke baffle 30 in this embodiment is simpler than the connection manner between the drive mechanism 11 and the first smoke baffle 30 mentioned in the foregoing embodiment. The relevant structure of this alternative embodiment is simpler, facilitating the quick assembly of the drive mechanism 11 and the mounting mechanism 80 by the operator.

[0089] Embodiment Two

[0090] The range hood disclosed in Embodiment One needs to drive at least two smoke baffles to move by setting at least two sets of drive mechanisms 11. The number of drive mechanisms 11 that need to be set in the range hood of Embodiment One is relatively large. The overall volume of at least two sets of drive mechanisms 11 is relatively large, the structure is relatively complex, the energy consumption is relatively high, and the control method is relatively complex.

[0091] To solve the above problems, the present disclosure discloses a range hood in this embodiment. The structure of the range hood in the present disclosure embodiment is basically the same as that of the range hood in Embodiment One, and the main difference between the two lies in the setting form of the drive device 10.

[0092] As Figure 10 and Figure 11As shown in the figure, the driving device 10 of the present disclosure embodiment includes a driving mechanism 11 and a transmission assembly 12. At least two smoke baffle plates are in transmission connection with the driving mechanism 11 through the transmission assembly 12, and the driving mechanism 11 can synchronously flip at least two smoke baffle plates through the transmission assembly 12. Only one set of driving mechanism 11 is provided in the present disclosure embodiment to achieve the synchronous flipping of at least two smoke baffle plates. Compared with the two sets of driving mechanisms 11 in the first embodiment, the driving device 10 of the present disclosure embodiment has a relatively smaller volume, a relatively simpler structure, relatively lower energy consumption, and a relatively simpler control method.

[0093] In an alternative embodiment, as Figure 10 and Figure 11 shown, the smoke baffle plate includes a first smoke baffle plate 30 and a second smoke baffle plate 40. The first smoke baffle plate 30 and the second smoke baffle plate 40 are symmetrically arranged. The center line of the driving device 10 coincides with the symmetry line of the first smoke baffle plate 30 and the second smoke baffle plate 40, which is convenient for the driving device 10 to synchronously drive the first smoke baffle plate 30 and the second smoke baffle plate 40, and realizes the rational layout of the driving device 10, the first smoke baffle plate 30, and the second smoke baffle plate 40 in a limited space.

[0094] In an alternative embodiment, as Figure 10 and Figure 11 shown, the driving mechanism 11 includes a second body 111 and a second output end 112 that can move relative to it in the up and down direction (i.e., the first direction). The second body 111 is arranged on the mounting mechanism 80. The second output end 112 is respectively in transmission connection with the first smoke baffle plate 30 and the second smoke baffle plate 40 through the transmission assembly 12. By the simple linear motion of the second output end 112 relative to the second body 111, the synchronous flipping of the first smoke baffle plate 30 and the second smoke baffle plate 40 can be achieved. The structure of the driving mechanism 11 is simple and convenient for installation. Specifically, the driving mechanism 11 can be a linear output driving mechanism. The linear output driving mechanism can be a linear output motor, a linear output cylinder, a linear guide rail, etc. It can also be a motor cooperating with a gear and rack assembly, or a motor cooperating with a multi-link assembly, or a motor cooperating with a crank-slider structure, etc. All structures or components that can achieve linear motion output are within the protection scope of this alternative embodiment.

[0095] In an alternative embodiment, as Figure 10 and Figure 11 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 second 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 plate 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 plate 40.

[0096] If the setting position of the second output end 112 is at the upper end of the second body 111, when the second output end 112 is at a low position, the first smoke baffle 30 opens the first air inlet 21111, and when the second output end 112 is at a high position, the second smoke baffle 40 opens the second air inlet 21121. When the second output end 112 moves upward, that is, from Figure 10 state switches to Figure 11 state, the second 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 air inlet 21111, 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 air inlet 21121. Through the up-and-down movement of the second output end 112, the synchronous opening or closing of the first air inlet 21111 and the second air inlet 21121 is realized. By adjusting the position and stroke of the second output end 112, the opening and closing angles of the first smoke baffle 30 and the second smoke baffle 40 are adjusted, so that the air intake of the first air inlet 21111 and the second air inlet 21121 can be adjusted. In an alternative embodiment, the second output end 112 can also be arranged at the lower end of the second body 111, and the above technical effects can also be achieved.

[0097] In an alternative embodiment, as Figure 10 and Figure 11 shown, the range hood further includes a guiding mechanism 50. The guiding mechanism 50 is arranged between the mounting member 121 and the mounting mechanism 80. The guiding mechanism 50 is used to make the mounting member 121 move in the up-and-down direction without skew, so as to realize the precise driving of the first smoke baffle 30 and the second smoke baffle 40.

[0098] In an alternative embodiment, as Figure 10 and Figure 11 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 mounting mechanism 80. 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, the precise guiding effect of the mounting member 121 moving in the up-and-down direction can be realized.

[0099] In an alternative embodiment, the guiding mechanism 50 is arranged as at least two, and two of the guiding mechanisms 50 are arranged in the front-back direction. By arranging at least two guiding mechanisms 50, the rotation of the mounting member 121 during the up-and-down movement can be avoided.

[0100] Since the smoke collecting hood 21 is very thin, it is not easy to place a relatively large driving device 10 inside the smoke collecting hood 21. In an alternative embodiment, as Figure 10 and Figure 11 shown, the driving device 10 is located between the first smoke inlet 21111 and the second smoke inlet 21121. The driving device 10 is located inside the main chassis 60, effectively utilizing the space at the connection position between the main chassis 60 and the smoke collecting hood 21 to accommodate the driving device 10. The main chassis 60 can completely shield the driving device 10, and the overall shape of the range hood is more aesthetically pleasing.

[0101] In an alternative embodiment, of course, part or all of the driving device 10 can also be arranged outside the main chassis 60, facilitating the user to check and maintain the state of the driving device 10.

[0102] Embodiment Three

[0103] 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 Two. The main difference between the two is that as Figure 12 and Figure 13 shown, 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 mounting mechanism 80, the connecting member 124 is fixedly connected to the second 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 left-right direction (i.e., the second direction). The other end of the first connecting rod 122 is fixedly connected to the first smoke baffle 30. The middle 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 left-right direction. The other end of the second connecting rod 123 is fixedly connected to the second smoke baffle 40. The middle of the second connecting rod 123 is rotatably connected to the mounting mechanism 80. 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 mechanisms 11. Compared with the two sets of driving mechanisms 11 in Embodiment One, the driving device 10 in the present disclosure embodiment has a smaller volume, a simpler structure, lower energy consumption, and a simpler control method.

[0104] Specifically, as Figure 12 and Figure 13As shown, the connecting member 124 includes a connecting member body 1241 and a slide rail 1242 that are fixedly connected. The connecting member body 1241 is fixedly connected to the second 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.

[0105] Embodiment 4

[0106] An 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 2. The main difference between the two is that as Figure 14 shown, the structure of the transmission assembly 12 is different. Specifically, the driving mechanism 11 is a motor. The motor includes a third body 113 and a third output end 114 that can rotate relative to it. The transmission assembly 12 includes a first gear 127 and a second gear 128 that are meshed 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 mounting mechanism 80. The second smoke baffle 40 includes a second rotating shaft and a second baffle body that are fixedly connected. The second rotating shaft is rotatably connected to the mounting mechanism 80. 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. The first rotating shaft 31 is coaxially fixed to the third output end 114. When the motor works, the third output end 114 drives the first rotating shaft 31 and the first baffle body 32 to rotate. Under the transmission action of the first gear 127 and the second gear 128, the second rotating shaft and the second baffle body can be synchronously flipped. The cooperation of the first gear 127 and the second gear 128 has high reliability, large load-bearing capacity, long service life and strong adaptability.

[0107] In an alternative embodiment, it can also be that the third output end 114 is coaxially fixed to the second rotating shaft, and the above effect can also be achieved.

[0108] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, and are not limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
