Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oil fume treatment device. Background Technology

[0002] Range hoods are widely used because they quickly remove cooking fumes, improving the cooking environment. When installing a range hood, it's essential to maintain sufficient distance between it and the cooktop to accommodate pots and pans. However, when cooking produces a large amount of fumes, some may escape from the sides, resulting in a less effective improvement in the kitchen environment.

[0003] In related technologies, some range hoods have flaps on both sides, which are driven by electric actuators to flip outwards to collect smoke and reduce its escape. However, electric actuators are not only expensive but also bulky, resulting in high manufacturing costs and large size for smoke treatment devices. Utility Model Content

[0004] The purpose of this invention is to provide an oil fume treatment device that adjusts the position of the smoke baffle through a magnetic mechanism, which has a compact structure and low cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The fume treatment device includes:

[0007] A frame assembly, wherein the frame assembly is configured to form a smoke collection chamber and a slide rail;

[0008] A smoke baffle and a magnetic mechanism, the magnetic mechanism being configured to lock the smoke baffle in a retracted position within the frame assembly, or to allow the smoke baffle to move along the slide to at least partially extend out of the frame assembly.

[0009] As an alternative, the magnetic mechanism includes an electromagnetic component that applies a force to the smoke baffle along the extension direction of the slide rail. The magnitude and / or direction of the magnetic field generated by the electromagnetic component are adjustable to drive the smoke baffle to slide along the slide rail.

[0010] As an alternative, the electromagnetic component includes an electromagnet disposed at the top of the slide rail and with adjustable current magnitude and / or direction; at least a portion of the smoke baffle is made of a ferromagnetic material, and the electromagnet is capable of generating a magnetic attraction force on the smoke baffle; or

[0012] The electromagnetic assembly includes two electromagnets, one of which is fixed to the top of the slide rail and the other is connected to the top of the smoke baffle. The two electromagnets can generate magnetic attraction to each other, and the current magnitude and / or direction of at least one electromagnet is adjustable.

[0013] As an optional solution, the fume treatment device further includes a smoke concentration detector configured to detect the smoke concentration outside the smoke collection chamber, and the smoke concentration detector is electrically connected to the electromagnetic component.

[0014] As an optional solution, the fume treatment device includes at least two smoke baffles, each smoke baffle corresponding to one of the electromagnetic components; the fume treatment device includes at least two smoke concentration detectors, each smoke concentration detector corresponding to detect the smoke concentration outside one of the smoke baffles, and is electrically connected to the electromagnetic component at the corresponding smoke baffle.

[0015] As an alternative, the magnetic mechanism includes a permanent magnet assembly capable of locking the smoke baffle in the retracted position.

[0016] As an optional solution, the fume treatment device includes two smoke baffles, which are respectively disposed on the left and right sides of the air inlet of the fume collection chamber.

[0017] As an optional solution, the rack assembly includes:

[0018] A smoke hood, wherein the smoke hood is configured to form the smoke collection chamber;

[0019] A support assembly is provided inside the smoke collection chamber and surrounds the slide. The smoke collection hood is provided with an avoidance opening at the lower end of the slide, and the lower end of the smoke baffle can extend out of the smoke collection hood from the avoidance opening.

[0020] As an optional embodiment, the smoke baffle includes a baffle body and a stop portion disposed at the upper end of the baffle body, wherein the cross-sectional area of ​​the stop portion is larger than the cross-sectional area of ​​the baffle body; wherein:

[0021] The support assembly includes a limiting part located at the lower end of the slide rail. The limiting part has a through hole through which the baffle body can pass, and the limiting part can stop the stopping part; or

[0024] The beneficial effects of this utility model are:

[0025] This utility model discloses an oil fume treatment device equipped with a smoke baffle that can slide along a track. When the smoke concentration generated during cooking is low, the need for smoke extraction is small, and a magnetic mechanism locks the smoke baffle in a retracted position within the frame assembly, preventing it from interfering with the user's cooking operations. When the smoke concentration generated during cooking is high, the need for smoke extraction increases. The smoke baffle is pulled out of the frame assembly by the magnetic mechanism or by manual force. At this time, the smoke baffle can collect the smoke and concentrate the negative pressure outside the frame assembly above the stove, thereby improving the smoke extraction effect. Compared with the method of driving by an electric push rod, the magnetic mechanism is low in cost, thus reducing the overall manufacturing cost of the oil fume treatment device. Moreover, the magnetic mechanism is small in size, thus improving the structural compactness of the oil fume treatment device. Attached Figure Description

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] This embodiment provides an oil fume treatment device, which can be a range hood, integrated stove, etc. The following description uses a range hood as an example of an oil fume treatment device.

[0050] like Figure 1 and Figure 2 As shown, the fume treatment device includes a frame assembly 10 and a fan. The frame assembly 10 includes a fume hood 11, which encloses a fume collection chamber 113 with an air inlet 111. The fan is installed inside the fume collection chamber 113. When the fan is working, it creates a negative pressure in a certain area inside the fume collection chamber 113 and outside the air inlet 111, thereby drawing the fumes generated during cooking into the fume collection chamber 113 and finally exhausting them outdoors.

[0051] like Figure 1 As shown, the smoke hood 11 is generally a cuboid structure, and the air inlet 111 of the smoke collection chamber 113 is located on the bottom plate of the smoke hood 11. In this embodiment, the air inlet 111 includes air inlet a1111 and air inlet b1112. Air inlet a1111 is located in the middle area in the left-right direction of the frame assembly 10, and there are two air inlets b1112, which are located on the left and right sides of air inlet a1111 respectively.

[0052] like Figure 2 and Figure 3As shown, the fume treatment device also includes a filter mechanism 50 and a first drive assembly 71. The filter mechanism 50 is located at the air inlet a1111 and forms a fume collection chamber 113 with the fume collection hood 11. The first drive assembly 71 can drive the filter mechanism 50 to change its shape, so that the volume of the fume collection chamber 113 is adjustable. Without increasing the fan power, increasing the volume of the fume collection chamber 113 can improve the fume collection effect of the fume treatment device. Furthermore, the increased volume of the fume collection chamber 113 provides a smoother flow channel for the fumes, making it easier for the fumes to be drawn into the fume collection chamber 113, thereby improving the overall fume extraction effect. In addition, the increased volume of the fume collection chamber 113 can also provide more buffer space for the flow of fumes, reducing the collision and friction of fumes in the fume collection chamber 113, thereby reducing the operating noise of the range hood.

[0053] like Figures 1-3 As shown, the filter mechanism 50 includes a filter assembly 51, which is disposed at the air inlet a1111 and has a first form and a second form, such as... Figure 1 and Figure 2 As shown, in the first configuration, the filter assembly 51 is housed within the smoke collection hood 11, as... Figure 3 As shown, in the second configuration, the filter assembly 51 extends at least partially beyond the fume hood 11. In this embodiment, when the filter assembly 51 switches from the first configuration to the second configuration, the volume of the fume collection chamber 113 increases and the negative pressure expands outward, thereby improving the fume extraction effect and reducing noise. Furthermore, when the filter assembly 51 switches from the first configuration to the second configuration, the actual air intake position of the fume collection chamber 113 also expands outward, thus getting closer to the source of the fumes and further improving the fume extraction efficiency. It is understood that the volume of the fume hood 11 continuously changes during the switching process from the first configuration to the second configuration. By driving the filter assembly 51 to remain at any position during this process, the first drive assembly 71 can obtain different sizes of the fume collection chamber 113, thereby improving the flexibility of adjusting the fume extraction capacity of the fume treatment device.

[0054] In this embodiment, as Figure 2 and Figure 3As shown, the filter assembly 51 includes two mesh plates 511 arranged at an included angle. In a first configuration, the opening formed by the two mesh plates 511 faces downwards, and in a second configuration, the opening forms by the two mesh plates 511 faces upwards. Optionally, in some embodiments, both mesh plates 511 are flat plates, thus forming a standard V-shaped structure. In the first configuration, the two mesh plates 511 are inverted V-shaped, and in the second configuration, the two mesh plates 511 are upright V-shaped. In some embodiments, the mesh plates 511 can also be non-planar plates with a certain curvature. In this case, the two mesh plates 511 are constructed with a non-standard V-shaped structure, but in the first configuration, the opening of the non-standard V-shaped structure faces downwards, and in the second configuration, the opening of the non-standard V-shaped structure faces upwards. In this embodiment, the mesh openings on the positive V-shaped or inverted V-shaped filter assembly 51 are tilted, meaning the negative pressure port is tilted. Therefore, with the cooperation of the two mesh plates 511, it is beneficial to form a more uniform negative pressure environment in the area below and to the side of the air inlet a1111, thereby reducing the escape of oil fumes from the side and improving the overall oil fume extraction effect of the oil fume treatment device. In this embodiment, the two mesh plates 511 are arranged on the left and right respectively.

[0055] like Figure 3 As shown, two mesh panels 511 are pivotally connected via a first pivot 53 extending along a first direction, which in this embodiment is the front-to-back direction. The filter mechanism 50 also includes a mating member 52, with the end of the mesh panel 511 away from the first pivot 53 pivotally connected to the mating member 52 via a second pivot 64, which is parallel to the first pivot 53. At least one mating member 52 can move closer to or further away from the other mating member 52 along a second direction, allowing the filter assembly 51 to switch between a first and a second configuration. In this embodiment, the second direction is the left-to-right direction, which is perpendicular to the first direction.

[0056] In this embodiment, the first drive component 71 is an electric actuator, the output end of which is connected to the first pivot 63, in conjunction with... Figure 2 and Figure 3The general process of the filter assembly 51 switching from the first form to the second form is as follows: Under the drive of the first drive assembly 71, at least one mating member 52 moves away from the other mating member 52 along the second direction. During this process, one end of the mesh plate 511 rotates around the second pivot 64, while the other end rotates around the first pivot 53. The included angle formed by the lower sides of the two mesh plates 511 gradually increases, and the first pivot 53 gradually moves towards the outside of the smoke hood 11. When the two mesh plates 511 rotate to coplanarity, under the drive of the first drive assembly 71, the mating member 52 moves in the opposite direction (i.e., moves towards the other mating member 52 along the second direction). During this process, the two ends of the mesh plate 511 still rotate around the first pivot 53 and the second pivot 64 respectively. The included angle formed by the upper sides of the two mesh plates 511 gradually decreases and finally reaches the second form. The process of the filter assembly 51 switching from the second form to the first form is the reverse of the process of switching from the first form to the second form, and will not be described in detail here.

[0057] like Figure 3 and Figure 4 As shown, the fume treatment device also includes a baffle 60 and a second driving component (not shown in the figure). The second driving component can drive the baffle 60 to open and close the air inlet b1112. In this embodiment, a baffle 60 and a second driving component are provided at each air inlet b1112. By driving the baffle 60 to open and close the air inlet b1112 through the second driving component, the actual air inlet position of the entire fume collection chamber 113 can be changed. In summary, the fume treatment device of this embodiment, by providing a variable-form filter assembly 51 at the air inlet a1111, can realize the volume adjustment of the inner cavity of the fume collection chamber 113, thereby realizing the expansion of the actual air inlet position and negative pressure, thus improving the fume extraction effect; and by setting the air inlet b1112, and changing the opening degree of the air inlet b1112 by the baffle 60 when the filter assembly 211 is in the first or second form, the fume treatment device can select the volume of the fume collection chamber 113. Based on this, further options are available for whether to open the air inlet b1112 and the opening degree of the air inlet b1112 (i.e., the smoke inlet position in the left and right directions). In other words, the fume treatment device can coordinate the distribution of negative pressure from multiple dimensions, such as the air inlet position a1111, the number of air inlets b1112 that are open, and the opening degree of each air inlet b1112, so that the negative pressure distribution outside the smoke collection chamber 113 matches the smoke concentration distribution, making the negative pressure distribution outside the smoke collection chamber 113 more reasonable, thereby improving the efficiency of fume extraction.

[0058] like Figure 3 and Figure 4As shown, the baffle 60 is disposed at the mating member 52. In this embodiment, the baffle 60 is connected to the smoke hood 11. Specifically, the front and rear ends of the baffle 60 are slidably connected to the front and rear side plates of the smoke hood 11 respectively via guide rail sliders or protruding groove structures. When the baffle 60 closes the corresponding air inlet b1112, a first slide 601 extending in the second direction can be formed between the baffle 60 and the bottom plate of the smoke hood 11, and the mating member 52 can slide back and forth along the corresponding first slide 601. It should be noted that the "corresponding first slide 601" here refers to the first slide 601 formed by the baffle 60 and the smoke hood 11 corresponding to the position of the mating member 52. The first slide 601 formed by the baffle 60 and the smoke hood 11 can play a good guiding role in the sliding direction of the mating member 52, thereby ensuring smooth switching of the filter assembly 21 and accurate adjustment of the volume of the smoke collection chamber 113.

[0059] like Figure 3 and Figure 4 As shown, the baffle 60 includes a main plate 61 and a protrusion 62. One end of the main plate 61 along the second direction overlaps with the mating member 52, and the protrusion 62 is connected to the other end of the main plate 61 along the second direction and abuts against the smoke hood 11. Specifically, the protrusion 62 abuts against the bottom plate of the smoke hood 11, and a first slide 601 is formed between the main plate 61 and the bottom plate of the smoke hood 11. The protrusion 62 can stop the corresponding mating member 52. On the one hand, the setting of the protrusion 62 keeps the main plate 61 and the bottom plate apart, thereby forming a stable first slide 601 for the mating member 52 to slide. On the other hand, the protrusion 62 also serves to stop and limit the mating member 52, ensuring that the mating member 52 can move according to the preset path, thereby ensuring that the filter assembly 21 can accurately switch between the first and second forms.

[0060] There is a certain distance between the bottom of the fume extraction device and the stove. When cooking produces a large amount of fumes, some of them will escape from the sides, resulting in poor kitchen environment improvement. Related technologies use flaps on both sides of the range hood, driven by electric actuators to flip the flaps outwards to collect the fumes and reduce their escape. However, electric actuators are expensive and bulky, making the range hood's structure less compact.

[0061] In this regard, such as Figure 2 and Figure 5As shown, the fume treatment device also includes a smoke baffle 20 and a magnetic mechanism. The frame assembly 10 is further surrounded by a slide rail 121. The smoke baffle 20 can slide within the slide rail 121. The magnetic mechanism can lock the smoke baffle 20 in a retracted position within the frame assembly 10, or allow the smoke baffle 20 to move along the slide rail 121 until it at least partially extends out of the frame assembly 10. Therefore, when the concentration of smoke generated during cooking is low, the demand for fume extraction is low. The magnetic mechanism locks the smoke baffle 20 in the retracted position within the frame, preventing the smoke baffle 20 from interfering with the user's cooking operations. When the concentration of smoke generated during cooking is high, the demand for fume extraction increases. The smoke baffle 20 is pulled out of the frame assembly 10 by the magnetic mechanism or by manual force. At this time, the smoke baffle 20 can collect the smoke and reduce the negative pressure outside the frame assembly 10. Figure 2 The area within the middle dashed line and Figure 5 The area between the two smoke baffles 20 is a negative pressure area, which is concentrated above the stove, thereby improving the oil fume extraction effect; compared with the method of driving by electric push rod, the magnetic mechanism is cheaper, thus reducing the overall manufacturing cost of the oil fume treatment device; and the magnetic mechanism is small in size, thus improving the structural compactness of the oil fume treatment device.

[0062] Specifically, the frame assembly 10 also includes a support assembly 12, which is disposed within the smoke collection chamber 113 and forms a slide 121, thereby making the overall appearance of the fume treatment device smoother and more aesthetically pleasing. The smoke hood 11 has a clearance opening 112 corresponding to the lower end of the slide 121 to ensure that the lower end of the smoke baffle 20 can extend out of the smoke hood 11 through the clearance opening 112. A magnetic mechanism is installed inside the smoke hood 11. In some embodiments, the magnetic mechanism is fixed to the smoke baffle 20 and / or the support assembly 12. In some embodiments, the magnetic mechanism is fixed to the smoke baffle 20 and / or the smoke hood 11. It is understood that the installation position varies depending on the composition of the magnetic mechanism, as detailed below.

[0063] In some embodiments, such as Figure 2 and Figure 5As shown, the fume treatment device includes two slides 121, which are respectively located on the left and right sides of the air inlet 111. Each slide 121 contains a baffle plate 20. When both baffle plates 20 extend from the frame assembly 10 simultaneously, the negative pressure area is better concentrated above the cooktop, preventing fumes from escaping from the left and right sides, thus greatly improving the smoke extraction effect. Furthermore, the baffle plates 20 on both sides have minimal impact on the user's cooking operations in front of the frame assembly 10. Of course, during the use of the fume treatment device, depending on the distribution of the generated fumes, only one baffle plate 20 can extend from the frame assembly 10, while the other baffle plate 20 remains in the retracted position, increasing the flexibility of the fume treatment device. In other embodiments, the fume treatment device may also be equipped with one, three, or more baffle plates 20; no specific limitation is made here.

[0064] like Figure 2 and Figure 5 As shown, the slide 121 extends vertically, and the smoke baffle 20 is located in a vertical plane and can move up and down along the slide 121. Therefore, when at least part of the smoke baffle 20 extends outside the frame assembly 10, the projection of the smoke baffle 20 in the horizontal plane will not exceed the projection of the frame assembly 10 in the horizontal plane. Thus, when installing the fume treatment device, it is not necessary to reserve clearance space on the left and right sides of the fume treatment device, making the fume treatment device suitable for scenarios with limited installation space. Furthermore, in this embodiment, the plane where the smoke baffle 20 is located is perpendicular to the left and right direction. With this arrangement, the projection of the smoke baffle 20 in the horizontal plane is a line segment extending in the front and back direction. Therefore, it can be installed close to the inner wall of the frame assembly 10 without occupying too much space in the left and right direction, and without interfering with other structures inside the frame assembly 10.

[0065] In some embodiments, the slide 121 can extend outwards from top to bottom, with the two smoke baffles 20 projecting in a figure-eight shape in the vertical plane. Therefore, when the smoke baffles 20 extend into the rack assembly 10, they will extend beyond the rack assembly 10 in the left and right directions. This arrangement better prevents the smoke baffles 20 from interfering with the user's cooking operations. In other embodiments, the slide 121 can extend vertically, but the smoke baffles 20 can be inclined, such as the two smoke baffles 20 projecting in a figure-eight shape in the horizontal plane. In this solution, the projection of the smoke baffles 20 in the horizontal plane after extending out of the rack assembly 10 will not exceed the rack assembly 10, but the slide 121 will occupy a larger space in the left and right directions.

[0066] To prevent the smoke baffle 20 from falling completely out of the rack assembly 10, such as Figure 2As shown, the smoke baffle 20 includes a baffle body 21 and a stop portion 22 disposed on the upper end of the baffle body 21. The cross-sectional area of ​​the stop portion 22 is larger than the cross-sectional area of ​​the baffle body 21. The stop portion 22 is used to cooperate with the frame assembly 10 to limit the movement and prevent the smoke baffle 20 from falling out of the frame assembly 10.

[0067] Optionally, such as Figure 2 and Figure 5 As shown, the cross-sectional area of ​​the clearance opening 112 is larger than the cross-sectional area of ​​the baffle body 21 and smaller than the cross-sectional area of ​​the stop portion 22. This allows the smoke hood 11 to allow the baffle body 21 to extend out of the smoke hood 11 while limiting the stop portion 22, preventing the smoke baffle 20 from falling completely out of the frame assembly 10. In this solution, only the size of the clearance opening 112 needs to be set within a suitable range; no other components need to be added, thus simplifying the structure of the frame assembly 10 and reducing the cost of the fume treatment device. In some embodiments, such as... Figure 5 As shown, the smoke hood 11 has an arc-shaped portion 114 located below the support assembly 12. There is a certain gap between the arc-shaped portion 114 and the lower end of the support assembly 12. In this design, when the stop portion 22 is stopped at the clearance opening 112, the smoke baffle 20 can be manually moved to swing left and right, thereby improving the flexibility of the smoke baffle 20. In some embodiments, such as... Figure 6 As shown, the lower end of the support component 12 is fitted to the corresponding part of the smoke collection hood 11. In this design, the stop part 22 can always be located inside the slide rail 121, thus avoiding the problem of the smoke baffle 20 not being aligned with the slide rail 121 when it rises and getting stuck.

[0068] Optionally, such as Figure 7 As shown, the support assembly 12 includes a limiting part 122, which is located at the lower end of the slide rail 121. The limiting part 122 has a through hole 123 through which the baffle body 21 can pass. The limiting part 122 can stop the stop part 22. This not only reliably limits the smoke baffle 20, preventing it from falling out of the frame assembly 10, but also ensures that the stop part 22 remains within the slide rail 121, thus preventing the smoke baffle 20 from jamming when it rises and not aligning with the slide rail 121.

[0069] like Figure 2 As shown, in this embodiment, when the smoke baffle 20 is in the retracted position, the support assembly 12 surrounds the top and sides of the smoke baffle. That is, the slide 121 only has an opening at its lower end. This design ensures that the lower end of the smoke baffle 20 can extend out of the slide 121, while minimizing the possibility of oil fumes from the smoke collection hood 11 entering the slide 121 and accumulating on its inner wall, thus ensuring smooth sliding of the smoke baffle 20. In some embodiments, such as... Figure 6 and Figure 7As shown, by setting the lower end of the support component 12 to abut against the bottom of the smoke hood 11, it is possible to prevent the oil fumes in the smoke collection chamber 113 from entering the slide 121 through the opening at the lower end of the slide 121. Optionally, the support component 12 can be a one-piece molded hood structure, or it can be a structure formed by two or more enclosures. When the support component 12 is set to be formed by at least two enclosures, it is convenient to install the smoke baffle 20, magnetic mechanism, etc. into the slide 121.

[0070] Optionally, the magnetic mechanism includes an electromagnetic component 31. The electromagnetic component 31 exerts a force on the smoke baffle 20 along the extension direction of the slide rail 121. The magnitude and / or direction of the magnetic force of the electromagnetic component 31 are adjustable, thereby enabling the electromagnetic component 31 to drive the smoke baffle 20 to slide along the slide rail 121. It can be understood that by changing the magnitude and direction of the current flowing through the electromagnetic component 31, the magnitude and direction of its magnetic force can be changed, thereby changing the force state of the smoke baffle 20 and realizing automatic control of the lifting and lowering movement of the smoke baffle 20.

[0071] In some embodiments, such as Figure 2As shown, the electromagnetic component 31 includes an electromagnet 311, which is disposed at the top of the slide rail 121 and has an adjustable current. At least part of the smoke baffle 20 is made of ferromagnetic material, so that the electromagnetic component 31 can generate a magnetic attraction force on the smoke baffle 20. When the current supplied to the electromagnetic component 31 changes, the force state of the smoke baffle 20 changes, thereby realizing the lifting and lowering movement. In this embodiment, the electromagnet 311 can be fixed to the upper end of the support component 12 or fixed to the smoke collection hood 11. In this scheme, when the current of the electromagnet 311 is adjusted, the magnetic force of the electromagnet 311 on the smoke baffle 20 can be changed, thereby changing the force state of the smoke baffle 20. The method of controlling the lifting and lowering movement of the smoke baffle 20 by changing the current of the electromagnet 311 is roughly as follows: When the current supplied to the electromagnet 311 is large enough, the attraction force of the electromagnet 311 on the smoke baffle 20 is greater than the weight of the smoke baffle 20, and the smoke baffle 20 can be kept in the retracted position; based on this, when the current of the electromagnet 311 is reduced, so that the magnetic attraction force of the electromagnet 311 on the smoke baffle 20 is less than the sum of the weight and sliding resistance of the smoke baffle 20, the smoke baffle 20 can slide downward along the slide rail 121; when the smoke baffle... During the sliding process of the baffle plate 20, when the current of the electromagnet 311 is adjusted so that the magnetic attraction force of the electromagnet 311 on the baffle plate 20 is equal to the weight of the baffle plate 20 again, the baffle plate 20 can be suspended at a certain position on the slide rail 121. When the baffle plate 20 descends to the lowest position or is suspended at a certain position, when the current of the electromagnet 311 is increased so that its magnetic attraction force on the baffle plate 20 is greater than the sum of the weight and sliding resistance of the baffle plate 20, the baffle plate 20 can move upward and eventually move to the retracted position. It should be noted that the cases in which at least part of the baffle plate 20 is made of ferromagnetic material include: first, the baffle plate 20 is entirely made of ferromagnetic material, so it can be attracted by the electromagnet 311; second, the baffle plate 20 includes a plate body and a ferromagnetic component connected to the plate body, which can be attracted by the electromagnet 311.

[0072] In some embodiments, such as Figure 8 As shown, the electromagnetic component 31 includes an electromagnet 311, which is connected to the top of the smoke baffle 20 and has an adjustable current. A ferromagnetic element 32 is disposed on the top of the slide rail 121, and the electromagnet 311 and the ferromagnetic element 32 generate a magnetic attraction force between them. When the current to the electromagnet 311 is changed, the magnetic attraction force of the ferromagnetic element 32 on the electromagnet 311 is changed, thereby changing the force state of the smoke baffle 20 connected to the electromagnet 311, thus driving the smoke baffle 20 to move up and down. It should be noted that the ferromagnetic element 32 on the top of the slide rail 121 can be an independent component separate from the support component 12, or it can be part of the support component 12.

[0073] In some embodiments, such as Figure 9As shown, the magnetic mechanism includes two electromagnets 311. One electromagnet 311 is fixed to the top of the slide rail 121, and the other electromagnet 311 is connected to the top of the smoke baffle 20. The two electromagnets 311 can generate a magnetic attraction force between them. In this scheme, by changing the magnitude and / or direction of the current of one electromagnet 311 or simultaneously changing the current of both electromagnets 311, the magnitude of the magnetic attraction force between the two electromagnets 311 can be changed, thereby changing the force state of the smoke baffle 20, thus driving the smoke baffle 20 to move up and down.

[0074] like Figure 2 As shown, the fume treatment device also includes a smoke concentration detector 40, which is configured to detect the smoke concentration outside the smoke collection chamber 113. The smoke concentration detector 40 is electrically connected to the electromagnetic component 31. When the smoke concentration detector 40 detects that the smoke concentration at the corresponding position outside the smoke collection chamber 113 is greater than a preset value, it indicates that a large amount of fumes are escaping. At this time, the controller of the fume treatment device changes the current of the electromagnetic component 31, causing the smoke baffle 20 to extend downwards to block the smoke and concentrate the negative pressure outside the fume treatment device, thereby improving the smoke extraction effect of the fume treatment device. When the smoke concentration detector 40 detects that the smoke concentration at the corresponding position outside the smoke collection chamber 113 is less than or equal to the preset value, the controller of the fume treatment device changes the current of the electromagnetic component 31 again, causing the smoke baffle 20 to move upwards back to the retracted position. It can be understood that the controller of the fume treatment device can also change the current of the electromagnetic component 31 according to the specific value of the smoke concentration detected by the smoke concentration detector 40, so that the smoke baffle 20 is suspended at a certain position on the slide rail 121.

[0075] like Figure 2 As shown, each smoke baffle 20 is configured with an electromagnetic component 31. The fume treatment device includes two smoke concentration detectors 40. Each smoke concentration detector 40 detects the smoke concentration outside a smoke baffle 20 and is electrically connected to the electromagnetic component 31 at the corresponding smoke baffle 20. It should be noted that the outside of the smoke baffle 20 corresponding to the smoke concentration detector 40 refers to the outside of the frame assembly 10 adjacent to the smoke baffle 20. In this embodiment, the lifting and lowering movement of the two smoke baffles 20 can be independently controlled according to the smoke concentration at the corresponding position, ensuring that the fume treatment device's smoke extraction capacity near the corresponding smoke baffle 20 (corresponding to the position of the smoke baffle 20 in the slide 121) matches the smoke concentration outside the corresponding smoke baffle 20, thereby achieving a reasonable distribution of negative pressure and ultimately ensuring a better smoke extraction effect. It can be understood that for schemes with three or more smoke baffles 20, the number of smoke concentration detectors 40 can be set accordingly. Optionally, as Figure 2As shown, the smoke concentration detector 40 can be embedded in the smoke collection hood 11, so that the smoke concentration detector 40 can both contact the oil fumes outside the frame assembly 10 for detection and be housed inside the frame assembly 10 to prevent the smoke concentration detector 40 from being damaged by external objects.

[0076] Optionally, in some embodiments, the magnetic mechanism does not include an electromagnetic component 31, but instead includes a permanent magnet component. The permanent magnet component can hold the smoke baffle 20 in the retracted position. When smoke blocking is required, the smoke baffle 20 can be manually pulled out of the frame assembly 10 or pushed back into the frame assembly 10. In this design, to facilitate manual operation of the smoke baffle 20, components such as an operating rod connected to the smoke baffle 20 can be provided.

[0077] In some embodiments, such as Figure 10 As shown, the permanent magnet assembly includes a permanent magnet 33 and a ferromagnetic component 32. The permanent magnet 33 is disposed on the top of the slide rail 121, and the ferromagnetic component 32 is disposed on the top of the smoke baffle 20. The permanent magnet 33 and the ferromagnetic component 32 attract each other to lock the smoke baffle 20 in the retracted position. In this embodiment, the permanent magnet 33 can be fixed inside or outside the support assembly 12, and this is not limited. In some embodiments, the positions of the permanent magnet 33 and the ferromagnetic component 32 can be interchanged.

[0078] In some embodiments, the permanent magnet assembly includes a permanent magnet 33 disposed on top of the slide 121, and the smoke baffle 20 is made of a ferromagnetic material. The permanent magnet 33 can attract the smoke baffle 20, thereby locking the smoke baffle 20 in the retracted position.

[0079] In some embodiments, such as Figure 11 As shown, the permanent magnet assembly includes two permanent magnets 33, one of which is fixed to the top of the slide rail 121 and the other is connected to the top of the smoke baffle 20. In this embodiment, the magnetic poles of the opposite portions of the two permanent magnets 33 are opposite, so that they can attract each other and retract the smoke baffle 20 to a retracted position.
