It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0072] Example 1

[0073] like Figures 1-2As shown in the figure, this embodiment of the present disclosure provides an oil fume treatment device 100. The oil fume treatment device 100 includes a main unit box (not shown in the figure) and a smoke collection chamber assembly connected to each other. The main unit box is equipped with a fan, and the smoke collection chamber assembly has an air inlet. When the main unit box is working, the oil fumes outside the oil fume treatment device 100 can enter through the air inlet. The oil fumes pass through the smoke collection chamber assembly and the main unit box in sequence. The oil fumes are purified in the main unit box, and the purified gas is discharged from the air outlet of the main unit box (not shown in the figure) to an external pipeline or indoors.

[0074] like Figure 1 and Figure 2 As shown, the smoke collection chamber assembly includes a housing 20, a flap mechanism 30, and a drive assembly 10. The flap mechanism 30 can rotate relative to the housing 20, and the drive assembly 10 can drive the flap mechanism 30 to switch between an open position and a closed position. When the flap mechanism 30 is in the open position, the flap mechanism 30 can achieve a better collection effect on the oil fumes, and the flap mechanism 30 can guide a large amount of oil fumes into the main unit box.

[0075] Currently, most kitchen fume treatment devices on the market use a single air inlet design. However, with the diversification of cooking methods, especially in home cooking, different types of cookware vary in height, diameter, and shape. For example, there are tall pans, flat-bottomed pans, deep pans, large-diameter cookware, and small-diameter cookware. These different types of cookware result in significant differences in the area and height where fumes are generated. A single air inlet design cannot flexibly handle different cookware situations, often causing fumes to accumulate in localized areas, affecting air quality and potentially harming the health of the cook.

[0076] In addition, many fume treatment devices 100 only achieve the capture of fumes in different states by adjusting the wind speed. However, inevitably, the fume extraction effect is poor at low wind speeds, while it generates more noise and energy consumption at high wind speeds. It is difficult to achieve a good capture of fumes in different areas, adapt the fume extraction power to different states of fumes, use low noise, and use low energy consumption.

[0077] To solve the above problems, such as Figure 1 and Figure 2As shown, the outer casing 20 is provided with a first air inlet 21 and a second air inlet 22, wherein the first air inlet 21 and the second air inlet 22 are arranged in a vertical direction. The flap mechanism 30 can cover the first air inlet 21. The fume treatment device 100 also includes a movable mechanism 40 and a control mechanism 50. The movable mechanism 40 can cover at least part of the second air inlet 22. The control mechanism 50 can obtain the vertical distance between the first air inlet 21 and the second air inlet 22 and the opening 210 of the pot 200, as well as the fume properties information P. The drive assembly 10 can... Based on the vertical distances between the first air inlet 21 and the second air inlet 22 and the opening 210 of the cookware 200, as well as the oil fume properties information P obtained by the control mechanism 50, the two types of parameters work together to comprehensively and adaptively adjust the position and posture of the flap mechanism 30 and the movable mechanism 40, so that the oil fume treatment device 100 is in different working modes. This enables better absorption of oil fumes from different types of cookware 200 in different areas and at different heights, preventing oil fumes from accumulating in local areas, ensuring better air quality, and protecting the health of users.

[0078] Furthermore, the fume treatment device 100 of this embodiment utilizes two types of parameters to comprehensively and adaptively adjust the position and posture of the flap mechanism 30 and the movable mechanism 40, enabling the fume treatment device 100 to operate in different modes. This eliminates the need for wind speed adjustment, as is common in existing technologies, to capture fumes in different states. Therefore, it avoids issues with poor smoke extraction due to wind speed variations, and also prevents excessive noise and energy consumption. Thus, by utilizing the fume treatment device 100 of this embodiment, it is possible to achieve consistently good fume capture in different areas, adapt smoke suction to different states of smoke, maintain low noise levels, and minimize energy consumption. This results in a dynamic balance between effective absorption of different forms of smoke, strong smoke suction, low noise operation, and low energy consumption, achieving optimal performance for the fume treatment device 100.

[0079] Specifically, such as Figures 1 to 16As shown, a cookware 200 is mounted on the stovetop 300. The drive assembly 10 can adjust the flip mechanism 30 and / or the movable mechanism 40 to keep the second air inlet 22 or the first air inlet 21 closest to the pot opening 210 of the cookware 200 in an open state. The state of the second air inlet 22 or the first air inlet 21 can be adjusted according to the height of different cookware 200s, thereby ensuring the shortest smoke intake path and improving the smoke extraction effect, achieving better absorption of oil fumes generated by cookware 200s of different heights. Furthermore, the drive assembly 10 can also adjust the opening angle of the flip mechanism 30 based on the detected oil fume properties P, further improving the smoke extraction effect across the range of oil fume generated by different types of cookware 200s. In summary, the oil fume treatment device 100 of this embodiment can flexibly handle oil fume situations generated by different cookware 200s, preventing the accumulation of oil fumes in localized areas, ensuring better air quality, and protecting the health of users.

[0080] In an alternative embodiment, such as Figures 1 to 16 As shown, the height of the cookware 200 has the greatest impact on the fume formation area. The shape and diameter of the cookware 200 also have some influence on the fume formation area, but this influence is relatively weak. Therefore, adjusting the height of the cookware 200, specifically choosing between the first air inlet 21 or the second air inlet 22, allows for a quick and primary adjustment of the fume treatment device 100. Next, further fine-tuning of the fume treatment device 100 is performed on secondary influencing parameters, achieving better absorption of fumes from different cookware. In summary, by adjusting these two aspects in sequence, a quick and precise adjustment of the fume treatment device 100 can be achieved.

[0081] In an alternative embodiment, such as Figure 1 and Figure 17 As shown, the fume treatment device 100 also includes a detection component 80, which includes a cookware property detection mechanism 81. The cookware property detection mechanism 81 is communicatively connected to the control mechanism 50. The cookware property detection mechanism 81 can detect the property information of the cookware 200. Based on the property information of the cookware 200, the control mechanism 50 can obtain the vertical distances between the first air inlet 21 and the second air inlet 22 and the opening 210 of the cookware 200, respectively. The control mechanism 50 can thus determine which air inlet is closest to the opening 210. For example, the cookware property detection mechanism 81 can be an ultrasonic distance detection mechanism, a laser distance detection mechanism, an image forming mechanism, etc. All cookware property detection mechanisms 81 that can directly or indirectly obtain the vertical distances between the first air inlet 21 and the second air inlet 22 and the opening 210 of the cookware 200 are within the protection scope of this disclosure.

[0082] In an alternative embodiment, such as Figure 1 and Figure 17 As shown, the detection component 80 also includes an oil fume property detection mechanism 82, which is communicatively connected to the control mechanism 50. The oil fume property detection mechanism 82 can detect the property information of the oil fume. The control mechanism 50 can obtain the diffusion and overflow of the oil fume based on the property information of the oil fume detected by the oil fume property detection mechanism 82, and can make precise adjustments to the flap mechanism 30 based on the diffusion and overflow of the oil fume.

[0083] For example, the physical property information of cooking fumes can be information on cooking fume concentration, cooking fume flow rate, cooking fume pressure, cooking fume temperature, etc. All physical property information of cooking fumes that can directly or indirectly reflect the diffusion and overflow of cooking fumes is within the protection scope of this disclosure embodiment. For example, the cooking fume physical property detection mechanism 82 can be a cooking fume concentration detection mechanism, a cooking fume flow rate detection mechanism, a cooking fume pressure detection mechanism, a cooking fume temperature detection mechanism, a thermal imaging mechanism, etc.

[0084] In an optional embodiment, the oil fume property detection mechanism 82 can be disposed on the outer surface of the flip plate mechanism 30, which can better detect the escape of oil fumes.

[0085] In an alternative embodiment, such as Figure 1 As shown, the oil fume property detection mechanism 82 can be set at the lower end of the flip plate mechanism 30, which can quickly acquire and provide feedback on the escape of oil fumes.

[0086] In an alternative embodiment, such as Figures 1 to 16 As shown, the second air inlet 22 includes at least two sets of spaced air inlets. The at least two sets of air inlets are arranged in the vertical direction. By setting more sets of air inlets at different heights, the second air inlet 22 can adapt to more cookware 200s of different heights. The fume treatment device 100 has a higher degree of precision in adapting to cookware 200s of different heights and can better meet the different needs of users.

[0087] For example, the drive assembly 10 includes a first drive mechanism 11 and a second drive mechanism 12. The first drive mechanism 11 and the second drive mechanism 12 are respectively communicatively connected to the control mechanism 50. The first drive mechanism 11 and the second drive mechanism 12 cooperate to adjust the flap mechanism 30 and / or the movable mechanism 40 so that the one closest to the pot opening 210 of the cookware 200 among the air inlet and the first air inlet 21 is in an open state. The opening angle of the flap mechanism 30 can also be adjusted according to the detected oil fume property information P. Through the setting of the first drive mechanism 11 and the second drive mechanism 12, the flap mechanism 30 and the movable mechanism 40 can be flexibly adjusted independently, thereby realizing the flexible adjustment of the oil fume treatment device 100 in different states.

[0088] In an alternative embodiment, such as Figure 1 and Figure 2 As shown, the second air inlet 22 includes a lower air inlet 222. The movable mechanism 40 has a first position. The first driving mechanism 11 can drive the movable mechanism 40 to the first position. When the movable mechanism 40 is in the first position, the movable mechanism 40 opens the lower air inlet 222 and blocks the middle air inlet 221. In this state, the fume treatment device 100 can effectively absorb the fumes generated by low-height cookware, such as flat-bottomed frying pans and baking pans.

[0089] like Figure 3 and Figure 4 As shown, after the cookware 200 has been cooking for a period of time, the single second air inlet 22 may not be able to effectively absorb the oil fumes, leading to the diffusion and overflow of oil fumes. When the oil fume property detection mechanism 82 detects that the oil fume property information exceeds the threshold, the control mechanism 50 controls the second drive mechanism 12 to open the flap mechanism 30. The flap mechanism 30 can achieve a better smoke collection effect, thereby achieving a better absorption effect of oil fumes by the oil fume treatment device 100.

[0090] It should be noted that the opening angle of the flap mechanism 30 can increase as the oil fume property information P detected by the oil fume property detection mechanism 82 increases, thereby achieving a matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0091] In an alternative embodiment, such as Figure 5 and Figure 6 As shown, the second air inlet 22 also includes a middle air inlet 221, wherein the middle air inlet 221 and the lower air inlet 222 are arranged from top to bottom. The movable mechanism 40 also has a second position. The first drive mechanism 11 can drive the movable mechanism 40 to switch between the first position and the second position. When the movable mechanism 40 is in the second position, the movable mechanism 40 opens the middle air inlet 221 and blocks the lower air inlet 222. In this state, the fume treatment device 100 can effectively absorb the fumes generated by medium-height cookware, such as frying pans and medium-height saucepans.

[0092] By driving the active mechanism 40 to switch between the first position and the second position through the first driving mechanism 11, the fume treatment device 100 can always achieve a good adaptation effect for low-height cookware and medium-height cookware.

[0093] like Figure 7 and Figure 8As shown, after the cookware 200 has been cooking for a period of time, the single central air inlet 221 may not be able to effectively absorb the oil fumes, leading to the diffusion and overflow of oil fumes. When the oil fume property detection mechanism 82 detects that the oil fume property information exceeds the threshold, the control mechanism 50 controls the second drive mechanism 12 to open the flap mechanism 30. The flap mechanism 30 can achieve a better smoke collection effect, thereby achieving a better absorption effect of oil fumes by the oil fume treatment device 100.

[0094] It should be noted that the opening angle of the flap mechanism 30 can increase as the oil fume property information P detected by the oil fume property detection mechanism 82 increases, thereby achieving a matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0095] In an alternative embodiment, such as Figure 2 , Figure 4 Figure 6 and Figure 7 As shown, the first driving mechanism 11 includes a first linear driving mechanism 111 and a first guide component 112. The first guide component 112 includes a first guide rail 1121 and a first slider 1122 slidably disposed thereon. The first guide rail 1121 is disposed on the housing 20. The first body 1111 of the first linear driving mechanism 111 is rotatably connected to the housing 20. The first output end 1112 of the first linear driving mechanism 111 is rotatably connected to the first slider 1122. The movable mechanism 40 is fixedly connected to the first slider 1122. When the first output end 1112 moves in a telescopic motion relative to the first body 1111, the first output end 1112 can drive the first slider 1122 to slide along the first guide rail 1121. The first slider 1122 can drive the movable mechanism 40 to slide along the extension direction of the first guide rail 1121, thereby enabling the movable mechanism 40 to block or open the middle air inlet 221 or the lower air inlet 222.

[0096] In an alternative embodiment, such as Figure 2 , Figure 4 Figure 6 and Figure 7 As shown, the first drive mechanism 11 is located on the back side of the first guide assembly 112. With this arrangement, when the first linear drive mechanism 111 is in the maximum retracted state, the movable mechanism 40 can be in a relatively low position. That is to say, the lower air inlet 222 can be set at a sufficiently low position to meet the needs of different cookware 200.

[0097] Of course, in an optional embodiment, the first body 1111 of the first linear drive mechanism 111 can also be fixedly connected to the outer shell 20. The first body 1111 is located directly below the first slider 1122, which can effectively save the size of the fume treatment device 100 in the thickness direction and realize the thin and light design of the fume treatment device 100.

[0098] In an optional embodiment, the first driving mechanism 11 may consist only of a first linear driving mechanism 111, with its first output end 1112 directly connected to the movable mechanism 40. This type of first driving mechanism 11 can also achieve rapid adjustment of the position of the movable mechanism 40, and its structure is simple. It should be noted that the structure of the first driving mechanism 11 can also be other structures capable of enabling the movable mechanism 40 to slide; all structures capable of enabling the movable mechanism 40 to move are within the protection scope of this disclosure.

[0099] In an optional embodiment, the movable mechanism 40 can be a single baffle (not shown in the figure), which has a simple structure and is easy to manufacture. The single baffle can also provide a good and sufficient shielding effect for the middle air inlet 221 or the lower air inlet 222, preventing oil fumes from overflowing from the movable mechanism 40.

[0100] In an alternative embodiment, such as Figure 2 , Figure 4 Figure 6 and Figure 7 As shown, the movable mechanism 40 includes a movable plate 41 and a second guide member 42. The movable plate 41 is fixedly connected to the second guide member 42, and the second guide member 42 is fixedly connected to the first slider 1122. The second guide member 42 and the first slider 1122 can achieve a stable connection.

[0101] In an alternative embodiment, such as Figures 1 to 8 As shown, a guide groove 23 is provided on the outer casing 20. The second guide member 42 is inserted into the guide groove 23 and slides along the guide groove 23. Through the cooperation between the second guide member 42 and the guide groove 23, the position switching of the movable mechanism 40 can be achieved. In addition, the cooperation between the second guide member 42 and the guide groove 23 is compact, which allows for the setting of a corresponding structure in a limited and narrow space to achieve a precise guiding effect for the movable mechanism 40.

[0102] In an alternative embodiment, such as Figures 1 to 8As shown, at least two second guide members 42 can be provided, and these at least two second guide members 42 are arranged at intervals along the width direction of the fume treatment device 100, thereby achieving a better guiding effect on the movable mechanism 40. In addition, by providing at least two second guide members 42, it is possible to prevent the movable mechanism 40 from rotating or deviating during movement, which can further improve the guiding effect on the movable mechanism 40.

[0103] In an optional embodiment, the second guide 42 can also be configured as a single unit, which makes the structure of the fume treatment device 100 simple and easy to assemble.

[0104] In an alternative embodiment, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figure 11 As shown, the movable mechanism 40 also has a third position. An opening 411 is provided on the movable mechanism 40. The first drive mechanism 11 can drive the movable mechanism 40 to switch between the first position, the second position and the third position. When the movable mechanism 40 is in the third position, the movable mechanism 40 opens the lower air inlet 222, and the opening 411 is directly opposite the middle air inlet 221. In this state, the fume treatment device 100 can effectively absorb a large amount of oil fumes generated by low-height or medium-height cookware, such as in scenarios where a lot of oil fumes are generated when using flat-bottomed frying pans, baking pans, woks, or medium-height saucepans.

[0105] By driving the active mechanism 40 to switch between the first position, the second position, and the third position through the first driving mechanism 11, the fume treatment device 100 can achieve a good adaptability to low-height and medium-height cookware in different fume scenarios.

[0106] like Figure 11 and Figure 12 As shown, when the cookware 200 has been cooking for a period of time, there may be a problem that the oil fume extraction effect is insufficient when the lower air inlet 222 and the middle air inlet 221 are opened at the same time, resulting in the diffusion and overflow of oil fumes. When the oil fume physical property detection mechanism 82 detects that the physical property information of the oil fume exceeds the threshold, the control mechanism 50 controls the second drive mechanism 12 to open the flap mechanism 30. The flap mechanism 30 can achieve a better smoke collection effect, thereby achieving a better absorption effect of oil fumes by the oil fume treatment device 100.

[0107] It should be noted that the opening angle of the flap mechanism 30 can increase as the oil fume property information P detected by the oil fume property detection mechanism 82 increases, thereby achieving a matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0108] In an alternative embodiment, such as Figure 13 and Figure 14 As shown, the first air inlet 21, the middle air inlet 221 and the lower air inlet 222 are arranged from top to bottom. When the cookware property detection mechanism 81 detects that the cookware 200 is at a high height, the second drive mechanism 12 can drive the flip plate mechanism 30 to be in the open state, thereby achieving a better absorption effect of the first air inlet 21 for oil fumes at a higher position. Such cookware includes steamers, saucepans, and cookware of a high height.

[0109] In an alternative embodiment, such as Figure 15 and Figure 16 As shown, the active mechanism 40 also has a fourth position. The first driving mechanism 11 can drive the active mechanism 40 to switch between the first position, the second position, the third position and the fourth position. After the cookware 200 has been cooking for a period of time, there may be a problem of insufficient oil fume absorption, which will cause the oil fume to spread and overflow. When the oil fume physical property detection mechanism 82 detects that the physical property information of the oil fume exceeds the threshold, the control mechanism 50 controls the first driving mechanism 11 to move. The first driving mechanism 11 puts the active mechanism 40 in the fourth position. The active mechanism 40 further pushes the flip plate mechanism 30. The flip plate mechanism 30 can achieve a better smoke collection effect, thereby achieving a better absorption effect of oil fume by the oil fume treatment device 100.

[0110] It should be noted that the opening angle of the flap mechanism 30 can increase as the oil fume property information P detected by the oil fume property detection mechanism 82 increases, thereby achieving a matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0111] In addition, such as Figure 15 and Figure 16 As shown, the movable mechanism 40, the flapping mechanism 30, and the outer casing 20 together constitute the external smoke inlet chamber 60. The movable mechanism 40 opens both the middle air inlet 221 and the lower air inlet 222, which is equivalent to moving the internal first air inlet 21 to an external and relatively lower position, improving the smoke extraction effect. At the same time, the flapping mechanism 30 plays a role in collecting smoke. For example, the opening 411 is located in front of and below the first air inlet 21, which can achieve a better absorption effect for oil fumes.

[0112] By driving the active mechanism 40 to switch between the first position, the second position, the third position and the fourth position by the drive component 10, the fume treatment device 100 can always achieve a good adaptation effect for cookware 200 of different heights.

[0113] In an alternative embodiment, such as Figure 14 and Figure 16As shown, the flap mechanism 30 includes a flap body 31 and a first side baffle 32. The flap body 31 is provided with a first side baffle 32 on both sides. When the movable mechanism 40 is in the fourth position, the flap body 31, the first side baffle 32, the movable mechanism 40 and the outer shell 20 together constitute the external smoke inlet chamber 60. The setting of the first side baffle 32 can realize the closed external smoke inlet chamber 60, which can prevent oil fumes from spreading or overflowing from the external smoke inlet chamber 60, and ensure that the oil fume treatment device 100 always has a good absorption effect on oil fumes.

[0114] like Figure 16 As shown, the outer casing 20 includes a front panel 24 and a rear panel 25 arranged at intervals along the front-to-back direction. A noise reduction cavity 26 is formed between the front panel 24 and the rear panel 25. A first air inlet 21 is disposed on the front panel 24. The flap body 31, the first side baffle 32, the movable mechanism 40, and the front panel 24 together constitute an external smoke inlet cavity 60. The noise reduction cavity 26 and the external smoke inlet cavity 60 are arranged at intervals. Through the independent arrangement of the noise reduction cavity 26 and the external smoke inlet cavity 60, the noise generated by the internal mechanism of the outer casing 20 can be effectively isolated, and the noise generated by the internal mechanism of the outer casing 20 can be prevented from being transmitted outward, thereby achieving a low-frequency effect for the fume treatment device 100.

[0115] In an alternative embodiment, such as Figure 14 and Figure 16 As shown, the second drive mechanism 12 includes a second output end 121 and a second body 123. The second output end 121 can extend and retract relative to the second body 123 in a straight line. The second body 123 is rotatably connected to the outer shell 20. The second output end 121 is connected to the flipping mechanism 30 in a transmission connection. When the second output end 121 extends and retracts relative to the second body 123, the second output end 121 can push the flipping mechanism 30 to rotate relative to the outer shell 20.

[0116] Furthermore, both the first drive mechanism 11 and the second drive mechanism 12 can directly or indirectly apply external force to the flap mechanism 30 to cause the flap mechanism 30 to rotate relative to the outer casing 20. To avoid interference between the flap mechanism 30 and the first drive mechanism 11 or the second drive mechanism 12, such as... Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 14 as well as Figure 16As shown, the second drive mechanism 12 also includes a first guide member 122, which is disposed on the second output end 121. The flip mechanism 30 includes a second side baffle 33, which is provided with a clearance groove 331. The first guide member 122 is inserted into the clearance groove 331 and can slide along the clearance groove 331. When the movable mechanism 40 pushes the flip mechanism 30 to move, it can avoid interference between the flip mechanism 30 and the first drive mechanism 11.

[0117] When the first drive mechanism 11 or the second drive mechanism 12 resets, there may be a problem of component jamming, which may cause the flip mechanism 30 to fail to reset properly, resulting in a gap between the flip mechanism 30 and the outer casing 20. On the one hand, this makes the fume treatment device 100 look unsightly when it is closed; on the other hand, it may cause the fumes inside the fume treatment device 100 to diffuse and overflow into the environment when it is closed, which may damage or affect the cleanliness of the environment and affect the user's experience.

[0118] In an alternative embodiment, to address the above-mentioned problems, such as Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 14 as well as Figure 16 As shown, the fume treatment device 100 also includes a reset member 70. The flap mechanism 30 is rotatably connected to the outer shell 20. One end of the flap mechanism 30 is rotatably connected to the outer shell 20, and the other end of the flap mechanism 30 is connected to the reset member 70. When the first drive mechanism 11 or the second drive mechanism 12 is reset, the reset member 70 can achieve a good reset effect of the flap mechanism 30, thereby achieving a tight contact between the flap mechanism 30 and the outer shell 20, thus avoiding gaps between the flap mechanism 30 and the outer shell 20. On the one hand, this ensures a good aesthetic appearance of the fume treatment device 100 in the closed state. On the other hand, it also prevents the fume inside the fume treatment device 100 from spreading and overflowing into the environment, ensuring a good cleanliness of the environment and a good user experience.

[0119] In an alternative embodiment, such as Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 14 as well as Figure 16 As shown, the reset member 70 is connected to the lower end of the flip mechanism 30. The reset member 70 only needs to provide a small force to apply a large torque to the flip mechanism 30, thereby achieving a better reset effect of the flip mechanism 30.

[0120] For example, such as Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 14 as well as Figure 16 As shown, the reset component 70 can be a spring, a reset cylinder, etc. All structures that can achieve the reset of the flip mechanism 30 are within the protection scope of this disclosure embodiment.

[0121] Example 2

[0122] like Figures 19-35 As shown, this embodiment of the present disclosure provides 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 1. The main difference is that the drive assembly 10 includes a third drive mechanism 13 and a fourth drive mechanism 14. The third drive mechanism 13 adjusts the flap mechanism 30 and / or the movable mechanism 40 so that the one closest to the pot opening 210 of the cookware 200 between the air inlet and the first air inlet 21 is in an open state. The fourth drive mechanism 14 can adjust the opening angle of the flap mechanism 30 according to the detected oil fume property information P. The fourth drive mechanism 14 only serves as the drive source for the flap mechanism 30, making the overall control and drive of the oil fume treatment device 100 simpler. The third drive mechanism 13 and the fourth drive mechanism 14 will not interfere with each other due to overly complex structures or control and drive.

[0123] Among them, such as Figures 19-35 As shown, the structure of the third drive mechanism 13 is the same as that of the first drive mechanism 11 in Embodiment 1. The third drive mechanism 13 includes a third linear drive mechanism 131 and a third guide component 132. The third guide component 132 includes a third guide rail 1321 and a third slider 1322 slidably disposed thereon. The third guide rail 1321 is disposed on the housing 20. The third body 1313 of the third linear drive mechanism 131 is rotatably connected to the housing 20. The third output end 1312 of the third linear drive mechanism 131 is rotatably connected to the third slider 1322. The movable mechanism 40 is fixedly connected to the third slider 1322. When the third output end 1312 moves in a telescopic motion relative to the third body 1313, the third output end 1312 can drive the third slider 1322 to slide along the third guide rail 1321. The third slider 1322 can drive the movable mechanism 40 to slide along the extension direction of the third guide rail 1321, thereby enabling the movable mechanism 40 to block or open the middle air inlet 221 or the lower air inlet 222.

[0124] like Figure 21As shown, the third drive mechanism 13 and the fourth drive mechanism 14 are respectively connected to the control mechanism 50. The third drive mechanism 13 and the fourth drive mechanism 14 cooperate to adjust the flap mechanism 30 and / or the movable mechanism 40 so that the one closest to the pot opening 210 of the cookware 200 among the air inlet and the first air inlet 21 is in the open state. The fourth drive mechanism 14 can adjust the opening angle of the flap mechanism 30 according to the detected oil fume property information P. Through the setting of the third drive mechanism 13 and the fourth drive mechanism 14, the flap mechanism 30 and the movable mechanism 40 can be flexibly adjusted independently, thereby realizing the flexible adjustment of the oil fume treatment device 100 in different states.

[0125] like Figures 19-35 As shown, the fourth drive mechanism 14 includes a fourth body 141 and a fourth output end 142. The fourth body 141 is fixedly connected to the outer casing 20, and the fourth output end 142 can perform linear telescopic movement relative to the fourth body 141. The fourth output end 142 abuts against the flip mechanism 30, and the fourth drive mechanism 14 can achieve a better driving effect on the flip mechanism 30. In addition, since the fourth output end 142 abuts against the flip mechanism 30, the state of the fourth drive mechanism 14 will not affect the working state of the third drive mechanism 13, thus avoiding jamming of the fume treatment device 100 during the switching of different states.

[0126] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
