Detailed Implementation

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0024] In the description of this invention, 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 invention based on the specific circumstances.

[0025] 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. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In the description of the embodiments disclosed herein, terms such as "upper," "lower," "left," and "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 the present invention. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no special meaning.

[0027] like Figure 1 As shown, this embodiment of the present disclosure provides an oil fume treatment device 1000, which includes a main unit 200 and a smoke collection mechanism 100. The main unit 200 is disposed at the upper end of the smoke collection mechanism 100 and is connected to the smoke collection mechanism 100. The smoke collection mechanism 100 is provided with an air inlet 211. The main unit 200 can generate negative pressure. The negative pressure generated by the main unit 200 allows the oil fumes outside the oil fume treatment device 1000 to pass through the air inlet 211, the interior of the smoke collection mechanism 100, and the main unit 200 in sequence. The filtered gas is finally discharged from the air outlet of the main unit 200.

[0028] In an alternative embodiment, such as Figures 1-4 As shown, the smoke collection mechanism 100 includes a smoke collection chamber body 10 and a movable cavity 20. The main unit 200 and the smoke collection chamber body 10 are housed in the mounting cavity 2100 of the cabinet 2000. The cabinet 2000 can effectively conceal the main unit 200 and the smoke collection chamber body 10, preventing them from being exposed in the kitchen environment and ensuring the aesthetics of the kitchen. Figures 1-3 As shown, the air inlet 211 is located on the movable cavity 20. The movable cavity 20 and the smoke collection cavity body 10 together constitute the smoke collection space 50. The movable cavity 20 can switch between a first position where it is stored in the smoke collection cavity body 10 and a second position where it extends out of the smoke collection cavity body 10. When the movable cavity 20 is in the first position, the cabinet 2000 can also achieve a good hiding effect on the movable cavity 20. When the movable cavity 20 is in the second position, the air inlet 211 can be closer to the oil fumes, thereby achieving a better absorption effect of the oil fume treatment device 1000 on the oil fumes and improving the oil fume extraction effect of the oil fume treatment device 1000.

[0029] In summary, as Figures 1-3 As shown, the fume treatment device 1000 maintains a small volume when it is in the storage state, while also increasing the smoke extraction area in the second position, effectively improving the fume extraction effect of the range hood. The downward movement of the air inlet 211 further enhances the fume extraction effect of the fume treatment device 1000, enabling better absorption of high-concentration fumes.

[0030] It should be noted that the fume treatment device 1000 can be a top-mounted fume extractor, a side-mounted fume extractor, a top-mounted fume extractor, a concealed fume extractor, etc. All devices and mechanisms capable of treating fumes are within the protection scope of this optional embodiment.

[0031] It should be noted that the fume extraction device 1000 is particularly suitable for modern integrated kitchens. When the device is off, it features a concealed design, allowing for fully integrated installation with the custom cabinetry 2000. This completely hides the fume extraction device from the kitchen environment, achieving a unity of function and aesthetics. This deep integration not only frees up the space occupied by traditional top-mounted or side-mounted range hoods, but is also especially suitable for open kitchens and small-to-medium-sized kitchens that prioritize minimalism. It seamlessly integrates fume extraction with the kitchen workspace, creating a spacious, clean, and high-quality cooking environment while efficiently removing smoke.

[0032] In an alternative embodiment, such as Figures 1-3 As shown, the smoke collection mechanism 100 also includes a flap 40, which can, as Figure 1 The recovery state shown and as follows Figure 3 The diagram shows the switching between the extended and unfolded states. (Example) Figure 1 As shown, when the flap 40 is in the retracted state, the fume treatment device 1000 can be well concealed within the cabinet 2000, preventing the main unit 200 and the fume collection chamber 10 from being exposed to the kitchen environment, thus ensuring the aesthetics of the kitchen environment. Figure 3 As shown, when the flap 40 is in the extended state, the flap 40 can form a certain space for oil fume to gather, thereby achieving a better oil fume absorption effect of the oil fume treatment device 1000.

[0033] In an optional embodiment, the fume treatment device 1000 further includes an oil cup 300, in which the oil cup 300 of the existing fume treatment device 1000 is only connected to the interior of the fume collection chamber body 10 or only connected to the movable chamber 20.

[0034] When the oil cup 300 is only installed in the smoke collection chamber body 10 and connected to the inside of the smoke collection chamber body 10, when the movable cavity 20 is in the second position, the movable cavity 20 extends out of the smoke collection chamber body 10. The oil inside the movable cavity 20 cannot be recovered by the oil cup 300, and the oil inside the movable cavity 20 will leak out from the movable cavity 20. The oil will flow to the outside of the oil fume treatment device 1000 and the stove, affecting the cleanliness of the kitchen and the user's experience.

[0035] When the oil cup 300 is only installed on and connected to the movable cavity 20, the oil cup 300 cannot recover the oil inside the smoke collection chamber 10 or the oil between the movable cavity 20 and the smoke collection chamber 10. The oil inside the movable cavity 20 will leak out from the gap between the movable cavity 20 and the smoke collection chamber 10, and the oil will flow to the outside of the fume treatment device 1000 and the stove, affecting the cleanliness of the kitchen and the user's experience.

[0036] To solve the above problems, such as Figures 4-9 As shown, the smoke-collecting chamber body 10 is provided with a first oil drain port 1511, and an oil cup 300 is disposed in the movable cavity 20 and communicates with the interior of the movable cavity 20. The movable cavity 20 can switch between a first position where it is housed in the smoke-collecting chamber body 10 and a second position where it extends out of the smoke-collecting chamber body 10. When the movable cavity 20 is in the first position, the first oil drain port 1511 is connected to the oil cup 300, and the oil cup 300 can effectively recover the oil inside both the movable cavity 20 and the smoke-collecting chamber body 10. In other words, when the movable cavity 20 is in the first position, the oil cup 300 can simultaneously prevent oil from leaking out of both the movable cavity 20 and the smoke-collecting chamber body 10. The oil cup 300 is separated from the smoke collection chamber body 10 when the movable cavity 20 is in the first position, thus preventing oil leakage from the fume treatment device 1000. When the movable cavity 20 is in the second position, the oil cup 300 is separated from the smoke collection chamber body 10, and the first oil leakage port 1511 is blocked. In other words, when the movable cavity 20 is in the second position, the oil cup 300 can achieve a better recovery effect of the oil inside the smoke collection chamber body 10. Since the first oil leakage port 1511 is blocked, the oil inside the smoke collection chamber body 10 can also avoid leakage from the first oil leakage port 1511. That is to say, the fume treatment device 1000 with the movable cavity 20 in the second position can always prevent oil leakage.

[0037] In summary, the arrangement of the fume treatment device 1000 in this embodiment ensures that the movable cavity 20, regardless of its state, can prevent the leakage of oil inside the fume treatment device 1000 and prevent oil from flowing to the outside of the fume treatment device 1000 and the stove, thus ensuring the cleanliness of the kitchen and providing users with a consistently good user experience.

[0038] In an alternative embodiment, such as Figures 4-7 as well as Figure 10As shown, the smoke collection chamber body 10 includes multiple baffles, which together constitute the smoke collection chamber body 10, enabling rapid assembly of the smoke collection chamber body 10. Specifically, the smoke collection chamber body 10 includes a front baffle 11, a back baffle 15, and two side baffles 12. The front baffle 11 and the back baffle 15 are arranged at intervals along the front-rear direction, and the side baffles 12 are disposed between the front baffle 11 and the back baffle 15. The two side baffles 12 are arranged along the left-right direction. The front baffle 11, the back baffle 15, and the two side baffles 12 together constitute a roughly rectangular smoke collection chamber body 10.

[0039] In an alternative embodiment, such as Figures 5-7 As shown, a first recovery trough 151 is provided on the back baffle 15, and a first opening 1512 is provided on the upper part of the first recovery trough 151. The oil inside the smoke collection chamber body 10 can be collected into the first recovery trough 151 through the first opening 1512 for temporary storage. A first oil drain 1511 is provided on the bottom plate of the first trough of the first recovery trough 151, and the oil temporarily stored inside the first recovery trough 151 can flow into the oil cup 300 through the first oil drain 1511. In other optional embodiments, a structure similar to the first recovery trough 151 can also be provided on the front baffle 11 and the side baffle 12, and the first recovery trough 151 at the corresponding positions can also play a good role in temporarily storing the oil.

[0040] In an alternative embodiment, such as Figure 7 and Figure 9 As shown, the smoke collection mechanism 100 of this embodiment further includes a sealing mechanism 400, which is disposed in the smoke collection chamber body 10. When the movable chamber 20 is in the first position, the sealing mechanism 400 is used to open the first oil leakage port 1511; when the movable chamber 20 is in the second position, the sealing mechanism 400 is used to seal the first oil leakage port 1511. By switching the movable chamber 20 between the first and second positions, the sealing mechanism 400 can adaptively open or seal the first oil leakage port 1511, realizing a quick and accurate match between the state of the first oil leakage port 1511 and the corresponding movable chamber 20. This can effectively prevent the leakage of oil inside the fume treatment device 1000, prevent oil from flowing to the outside of the fume treatment device 1000 and the stove, ensure the cleanliness of the kitchen, and ensure that users always have a better user experience.

[0041] In an alternative embodiment, such as Figures 7-9As shown, the sealing mechanism 400 includes a first mounting part 410, a reset part 420, and a movable part 430. The first mounting part 410 is disposed on the smoke collection chamber body 10. The first mounting part 410 is connected to the movable part 430 through the reset part 420. The oil cup 300 includes a trigger part 320. When the movable chamber 20 is in the first position, the trigger part 320 cooperates with the movable part 430 to open the first oil leakage port 1511. The cooperation between the trigger part 320 and the movable part 430 can achieve the precise opening effect of the first oil leakage port 1511 when the movable chamber 20 is in the first position. No additional position detection device for the movable chamber 20 is required, which makes the structure of the sealing mechanism 400 simpler. Furthermore, the triggering part 320 can only trigger the movable part 430 to change its state when the movable cavity 20 is actually in the first position. This can effectively prevent the movable part 430 from being accidentally triggered, prevent the first oil leak port 1511 from being accidentally opened, and ensure that the fume treatment device 1000 will not leak oil.

[0042] In an alternative embodiment, such as Figure 9 As shown, the movable part 430 includes a plug-in part 432, which can be a long rod-shaped structure. The long rod-shaped plug-in part 432 can be well plugged into the first oil leak port 1511, thereby achieving a good sealing effect of the movable part 430 on the first oil leak port 1511.

[0043] In other alternative embodiments, the movable element 430 may also be a sealing plate (not shown in the figure). The sealing plate can move or rotate horizontally relative to the smoke collection chamber body 10. By moving or rotating the sealing plate horizontally, a better switching effect of sealing or opening the first oil leakage port 1511 can be achieved.

[0044] In an alternative embodiment, such as Figure 7 and Figure 9 As shown, when the movable cavity 20 is in the second position, the reset member 420 is used to reset the movable member 430 so that the movable member 430 can block the first oil leak 1511. The reset member 420 enables the movable member 430 to be quickly reset, thereby achieving the effect of quickly blocking the first oil leak 1511.

[0045] For example, the reset component 420 can be a spring, a reset cylinder, a spring sheet, etc. All structures that can achieve the reset of the movable component 430 are within the protection scope of this optional embodiment, which will not be described in detail here.

[0046] In an alternative embodiment, such as Figure 9As shown, the movable part 430 includes a guide part 431. The first mounting part 410 is provided with a guide groove 411. The guide part 431 is inserted into the guide groove 411 and can slide along the guide groove 411. The reset part 420 is disposed in the guide groove 411 and is held by the second groove bottom plate of the guide groove 411 and the guide part 431. By sliding the guide part 431 in the guide groove 411, the guide part 431 can always apply a good force to the reset part 420 along the extension direction of the guide groove 411, which can prevent the sliding of the guide part 431 from deviating and ensure that the reset part 420 always has a good predetermined deformation effect.

[0047] In an alternative embodiment, such as Figure 9 As shown, the movable member 430 may further include a limiting part 433, which can cooperate with the first mounting member 410 to limit the upper limit position of the guide part 431, so as to avoid damage to the reset member 420 caused by excessive pressure from the guide part 431. The limiting part 433 can cooperate with the smoke collection chamber body 10 to limit the lower limit position of the movable member 430, so as to avoid damage to the movable member 430 caused by excessive downward movement.

[0048] In an alternative embodiment, such as Figures 4-6 As shown, the smoke collection chamber body 10 includes a filter mechanism 13. The filter mechanism 13 is located at the lower end of the air inlet 210 of the main unit box 200. The oil fumes enter the main unit box 200 after passing through the movable chamber 20 and the filter mechanism 13 in sequence. The filter mechanism 13 can perform preliminary filtration of the oil fumes in the smoke collection space 50. The gas after preliminary filtration then enters the main unit box 200 for further filtration. The filter mechanism 13 can achieve the preliminary filtration of inhaled oil fumes and can intercept oil in the oil fumes.

[0049] In an alternative embodiment, such as Figures 4-6 As shown, the filter mechanism 13 is provided with a second oil drain port 134, which is connected to the movable cavity 20. The oil intercepted by the filter mechanism 13 can drip into the movable cavity 20 through the second oil drain port 134. The oil dripping into the movable cavity 20 will eventually be collected in the oil cup 300 connected to the movable cavity 20, thus preventing the oil from dripping to the outside of the fume treatment device 1000.

[0050] In an alternative embodiment, such as Figures 4-6 As shown, the filter mechanism 13 is arranged to protrude downwards, and a second oil leakage port 134 is provided at the lowest position of the filter mechanism 13. The oil intercepted by the filter mechanism 13 can be gathered at the lowest position and leaked into the movable cavity 20 through the second oil leakage port 134. The downward protrusion of the filter mechanism 13 can achieve a better gathering effect on the oil on the filter mechanism 13.

[0051] In an alternative embodiment, such as Figures 4-7 As shown, the filtration mechanism 13 includes a first filter screen 131, a connecting plate 132, and a second filter screen 133 connected sequentially from front to back. The first filter screen 131 is inclined downward from front to back, and the second filter screen 133 is inclined upward from front to back. At least a portion of the second oil drain port 134 is arranged in the connecting area of ​​the first filter screen 131, the connecting plate 132, and the second filter screen 133. The oil on the first filter screen 131 can flow downward from front to back along the first filter screen 131, and the oil on the second filter screen 133 can flow downward from back to front along the second filter screen 133. Through the arrangement of the first filter screen 131 and the second filter screen 133, the oil can be better concentrated towards the second oil drain port 134 located in the middle position.

[0052] In an alternative embodiment, such as Figures 4-7 As shown, the connecting plate 132 includes a first guide plate 1321 and a second guide plate 1322 arranged in a left-right direction. The first guide plate 1321 is inclined downward from left to right, and the second guide plate 1322 is inclined downward from right to left. At least part of the second oil drain port 134 is arranged at the connection position of the first guide plate 1321 and the second guide plate 1322. The oil on the first guide plate 1321 flows downward from left to right, and the oil on the second guide plate 1322 flows downward from right to left, thereby realizing that the oil on the connecting plate 132 converges and flows towards the second oil drain port 134, so as to achieve better flow of oil towards the second oil drain port 134.

[0053] In an alternative embodiment, such as Figures 4-7 As shown, the movable cavity 20 includes a front connecting plate 22 and a rear connecting plate 23 arranged at intervals from front to back. The second oil drain 134 is arranged between the front connecting plate 22 and the rear connecting plate 23 in the front-back direction. The second oil drain 134 is always located in front of the rear connecting plate 23. The oil can drip directly into the movable cavity 20 through the second oil drain 134. The oil eventually flows into the oil cup 300 connected to the movable cavity 20 to prevent the oil from dripping onto the table surface.

[0054] In an alternative embodiment, such as Figure 5As shown, the movable cavity 20 is provided with a third oil drain port 216. When the movable cavity 20 is in the second position, the oil cup 300 has a second recovery tank 310, and the upper end of the second recovery tank 310 is provided with a second opening 3101. The second oil drain port 134, the third oil drain port 216, and the second opening 3101 are arranged sequentially from top to bottom and are positioned opposite each other, which can effectively shorten the flow path of the oil and enable the oil on the filter mechanism 13 to quickly and smoothly pass through the second oil drain port 134, the third oil drain port 216, and the second opening 3101 of the oil cup 300 before entering the oil cup 300 for temporary storage. The setting position of the second oil drain port 134 can prevent the oil from flowing from the second oil drain port 134 to the outside of the movable cavity 20, thus preventing the oil fume treatment device 1000 from leaking oil and ensuring a good cleanliness of the outside of the movable cavity 20.

[0055] In an alternative embodiment, such as Figures 4-7 As shown, the movable cavity 20 also includes a movable cavity body 21 with a third oil drain port 216. The upper end of the rear connecting plate 23 is movably connected to the filter mechanism 13, and the lower end of the rear connecting plate 23 is movably connected to the rear side of the movable cavity body 21. The oil cup 300 is located at the rear lower position of the movable cavity body 21 and is connected to the third oil drain port 216. The oil flowing out from the second oil drain port 134 can flow along the front plate surface of the rear connecting plate 23 into the movable cavity body 21. The rear connecting plate 23 can achieve a good drainage effect for the oil.

[0056] In an alternative embodiment, such as Figure 4 As shown, when the movable cavity 20 is in the first position, the rear connecting plate 23 is inclined downward from front to back. The oil stains on the wall of the rear connecting plate 23 are guided into the movable cavity 20 through the inclined surface. The oil eventually flows into the oil cup 300 at the lower rear position of the movable cavity 20 to prevent the oil from dripping onto the table surface.

[0057] In an alternative embodiment, such as Figure 10 and Figure 11 As shown, a guide groove 232 with an upper opening 2321 and a lower opening 2322 is provided on the rear connecting plate 23. The movable cavity body 21 can receive the oil flowing out from the lower opening 2322. The width of the guide groove 232 gradually decreases from top to bottom in the left and right direction. Through the setting of the guide groove 232, the oil can quickly gather into the lower opening 2322 and flow into the movable cavity body 21, effectively improving the oil collection efficiency.

[0058] In an alternative embodiment, such as Figure 4 as well as Figure 16As shown, the lower end of the rear connecting plate 23 is pivotally connected to the smoke collection chamber body 10, and the upper end of the rear connecting plate 23 is pivotally connected to the smoke collection chamber body 10. When the movable cavity 20 is in the first position, the second position, or any intermediate position, the connection through the pivoting of the entire shaft can improve the sealing effect between the lower end of the rear connecting plate 23 and the smoke collection chamber body 10, and also improve the sealing effect between the upper end of the rear connecting plate 23 and the smoke collection chamber body 10. This further improves the sealing effect of the smoke collection space 50, reduces air volume loss, and effectively improves the smoke extraction effect of the fume treatment device 1000. The fume extraction effect of the fume treatment device 1000 is good, preventing oil odors or oil from overflowing from the smoke collection space 50, ensuring a clean kitchen environment, and improving the user experience.

[0059] In an alternative embodiment, such as Figure 10 and Figure 11 As shown, the rear connecting plate 23 is pivotally connected to the movable cavity body 21 via a pivot shaft 24. A clearance port 241 is provided on the pivot shaft 24. The oil on the rear connecting plate 23 can enter the movable cavity body 21 after passing through the lower opening 2322 and the clearance port 241 in sequence. The clearance port 241 can avoid interference from the pivot shaft 24 and ensure that the oil flowing out from the lower opening 2322 can smoothly enter the movable cavity body 21.

[0060] In an alternative embodiment, such as Figure 4 As shown, the upper end of the front connecting plate 22 is movably connected to the smoke collection chamber body 10, and the lower end of the front connecting plate 22 is movably connected to the front side of the movable chamber body 21. The front connecting plate 22 includes a first drainage section 223. When the movable chamber 20 is in the first position, the first drainage section 223 is inclined downward from front to back. The first drainage section 223 can effectively guide the oil inside the movable chamber 20 to the movable chamber body 21, thereby achieving a better oil recovery effect of the oil cup 300.

[0061] In an alternative embodiment, such as Figure 5 As shown, the upper end of the front connecting plate 22 is movably connected to the smoke collection chamber body 10, and the lower end of the front connecting plate 22 is movably connected to the front of the movable chamber body 21. The front connecting plate 22 includes a second drainage section 221. When the movable chamber 20 is in the second position, the second drainage section 221 is inclined downward from front to back. The second drainage section 221 can effectively guide the oil inside the movable chamber 20 to the movable chamber body 21, thereby achieving a better oil recovery effect of the oil cup 300.

[0062] In an alternative embodiment, such as Figure 4 and Figure 5As shown, the active cavity body 21 includes an oil collection tank 218 and a base plate 217 with an air inlet 211. A third oil drain 216 is disposed on the oil collection tank 218. The base plate 217 is located above the front side of the third oil drain 216. The base plate 217 is inclined downward from front to back. The base plate 217 can guide the oil on it to the oil collection tank 218, thereby achieving a better oil recovery effect of the oil cup 300.

[0063] In summary, with the aforementioned structure, regardless of whether the movable cavity 20 is in the first or second position, the aforementioned structure can guide the oil inside the movable cavity 20 toward the oil cup 300, thereby achieving a better and smoother recovery effect of the oil cup 300 for the oil inside the movable cavity 20.

[0064] like Figure 4 , Figure 12 and Figure 13 As shown, the smoke collection chamber body 10 includes a front baffle 11, and the movable chamber 20 includes a front connecting plate 22 with a free end 2212. The front connecting plate 22 is disposed in the smoke collection chamber body 10 and arranged with the corresponding front baffle 11 along a first direction. When the movable chamber 20 is in the first position housed in the smoke collection chamber body 10, at least part of the front connecting plate 22 is inclined downward from back to front (i.e. along the first direction). The free end 2212 is located at the lower part of the front connecting plate 22 and abuts against or is spaced apart from the corresponding front baffle 11. When the movable chamber 20 is in the first position, the oil inside the smoke collection space 50 accumulates to a certain extent and flows along the front connecting plate 22 and forward and downward to the gap between the free end 2212 and the front connecting plate 22. The oil will flow from the gap between the free end 2212 and the front connecting plate 22 to the outside of the oil fume treatment device 1000 and the stove, affecting the cleanliness of the kitchen and the user's experience.

[0065] To solve the above problems, such as Figure 4 , Figure 12 and Figure 13 As shown, the front connecting plate 22 has an opening 2211 for receiving groove 2211. When the movable cavity 20 is in the first position of being housed in the smoke collection cavity body 10, the opening 22111 faces upward. When the oil inside the smoke collection space 50 accumulates to a certain extent, it will flow along the front connecting plate 22 and forward and downward and be collected into the receiving groove 2211. This can prevent the oil from flowing from the gap between the free end 2212 and the front connecting plate 22 to the outside of the oil fume treatment device 1000 and the stove, ensuring the cleanliness of the kitchen and improving the user experience.

[0066] In an optional embodiment, the structural design of the front connecting plate 22 can be applied to the rear connecting plate 23, the left connecting plate, the right connecting plate, etc., and can also achieve the above-mentioned effect. This optional embodiment does not elaborate on the structure of the rear connecting plate 23, the left connecting plate, the right connecting plate, etc.

[0067] In an alternative embodiment, such as Figure 13 As shown, the accommodating groove 2211 includes a first inclined surface 22112 and a second inclined surface 22113 arranged from back to front. When the movable cavity 20 is in the first position, the first inclined surface 22112 is inclined downward from back to front, and the second inclined surface 22113 is inclined upward from back to front. The first inclined surface 22112 and the second inclined surface 22113 are arranged at an angle. The cooperation of the first inclined surface 22112 and the second inclined surface 22113 can form a large accommodating space. The accommodating space can achieve a better recycling effect on the oil inside the smoke collection space 50. The accommodating groove 2211 with this structure can prevent the oil inside the accommodating groove 2211 from overflowing from the opening 22111.

[0068] In an alternative embodiment, such as Figure 4 , Figure 12 and Figure 13 As shown, the smoke collection mechanism 100 also includes a first sealing component 90. When the movable cavity 20 is in the first position, the first sealing component 90 is sandwiched between the connecting plate and the smoke collection cavity body 10. Along the first direction, the baffle is located on one side of the first sealing component 90, and at least part of the air inlet 210 of the main unit 200 is located on the other side of the first sealing component 90. The first sealing component 90 can block a portion of the oil overflowing from the air inlet 210 of the main unit 200 from flowing through the front connecting plate 22 to the gap between the free end 2212 and the front baffle 11, further preventing the oil from flowing from the gap between the free end 2212 and the front connecting plate 22 to the outside of the oil fume treatment device 1000 and the stove, further improving the cleanliness of the kitchen and further ensuring the user's experience.

[0069] In an alternative embodiment, such as Figure 12 and Figure 13As shown, the first sealing assembly 90 includes a third mounting member 91 and a fourth sealing body 92. The third mounting member 91 and the filter mechanism 13 of the smoke collection chamber body 10 together securely clamp the fourth sealing body 92, thereby achieving a stable installation effect for the fourth sealing body 92. For example, the third mounting member 91 and the filter mechanism 13 of the smoke collection chamber body 10 can be securely connected by screws, pins, snap-fits, etc. For example, the fourth sealing body 92 includes a clamping part 921 and an abutting part 922. The third mounting member 91 and the filter mechanism 13 together clamp the clamping part 921, and the abutting part 922 abuts against the front connecting plate 22, simultaneously achieving a secure connection between the fourth sealing body 92 and the filter mechanism 13, and providing a good sealing effect for the gap between the front connecting plate 22 and the filter mechanism 13.

[0070] For example, the fourth sealing body 92 can be made of an elastic material, thereby achieving a consistently good sealing effect between the fourth sealing body 92 and the movable cavity body 21, and also preventing damage or noise from hard impacts between the fourth sealing body 92 and the front connecting plate 22. For example, the elastic material can be made of flexible materials with elasticity such as silicone or rubber.

[0071] In an alternative embodiment, such as Figure 14 and Figure 16 As shown, when the movable cavity 20 is in the second position extending out of the smoke collection cavity body 10, the first inclined surface 22112 is inclined downward from front to back, the free end 2212 of the front connecting plate 22 is at the high point, and the accommodating groove 2211 is in a state of front high and back low. The oil temporarily stored in the accommodating groove 2211 can flow back to the smoke collection space 50, and the oil finally flows into the oil cup 300, thereby achieving the final oil recovery effect.

[0072] In an alternative embodiment, such as Figure 14 As shown, the front connecting plate 22 includes a second diversion section 221 and a third diversion section 222 connected to each other. The receiving groove 2211 is opened on the second diversion section 221. When the movable cavity 20 is in the second position extending out of the smoke collecting cavity body 10, the third diversion section 222 protrudes in the direction away from the corresponding front baffle 11. The third diversion section 222 can achieve a better diversion effect. The third diversion section 222 can guide the oil in the receiving groove 2211 to flow smoothly into the smoke collecting space 50. The oil can eventually be better recovered by the oil cup 300.

[0073] In an alternative embodiment, such as Figure 4 and Figure 16As shown, the movable cavity 20 includes a movable cavity body 21, and an air inlet 211 is disposed on the movable cavity body 21. When the movable cavity 20 switches from the first position to the second position, the movable cavity body 21 moves forward and downward relative to the smoke collection cavity body 10. When the movable cavity 20 is in the second position, the air inlet 211 is in a lower and forward position, so that the air inlet 211 is closer to the smoke source, effectively improving the smoke extraction effect of the oil fume treatment device 1000.

[0074] In an alternative embodiment, such as Figure 4 , Figure 16 and Figure 19 As shown, the movable cavity 20 also includes a front connecting plate 22, a rear connecting plate 23, and a linear drive mechanism 60. The upper end of the front connecting plate 22 is rotatably connected to the smoke collection cavity body 10, and the lower end of the front connecting plate 22 is rotatably connected to the movable cavity body 21. The lower end of the rear connecting plate 23 is rotatably connected to the smoke collection cavity body 10, and the upper end of the rear connecting plate 23 is rotatably connected to the smoke collection cavity body 10. One end of the linear drive mechanism 60 is rotatably connected to the smoke collection cavity body 10 or the main unit 200, and the other end of the linear drive mechanism 60 is rotatably connected to the front connecting plate 22, the rear connecting plate 23, or the movable cavity body 21. When the linear drive mechanism 60 performs a linear extension movement, the movable cavity body 21, the front connecting plate 22, and the rear connecting plate 23 all move forward and downward, thereby causing the smoke collection space 50 and the air inlet 211 to move forward and downward, achieving a better absorption effect of the air inlet 211 for oil fumes.

[0075] In an alternative embodiment, such as Figure 7 As shown, the linear drive mechanism 60 includes a linear drive body 61 and an output shaft 62. The output shaft 62 can move linearly relative to the linear drive body 61. The linear drive body 61 is rotatably connected to the smoke collection chamber body 10 or the main unit 200. The output shaft 62 is directly or indirectly rotatably connected to the front connecting plate 22, the rear connecting plate 23 or the movable chamber body 21. The output shaft 62 passes through the filter mechanism 13, which can avoid interference from the filter mechanism 13 to the output shaft 62 and ensure the smooth movement of the linear drive mechanism 60.

[0076] In an alternative embodiment, such as Figure 7 As shown, the smoke collection chamber body 10 includes a mounting base 17, which includes a fourth mounting component 171 and a connecting component 172 connected to each other. The fourth mounting component 171 is fixedly mounted on the rear connecting plate 23, and the output shaft 62 is rotatably connected to the connecting component 172, thereby achieving a smooth rotation effect between the output shaft 62 and the rear connecting plate 23.

[0077] In an alternative embodiment, such as Figure 7 and Figure 10As shown, the connector 172 includes a first end and a second end. The first end is rotatably connected to the output shaft 62, and the second end is fixedly connected to the fourth mounting member 171. Regardless of whether the movable cavity 20 is in the first position or the second position, the second end is always located below the first end. During the process of the movable cavity 20 being stationary or in motion, the connector 172 can always guide the oil to the rear connecting plate 23, and the oil eventually flows into the oil cup 300, preventing the oil from flowing to the outside of the fume treatment device 1000.

[0078] In an alternative embodiment, such as Figure 7 As shown, the smoke collection chamber body 10 includes a protective cover 16, which is located around the linear drive body 61. The rear side of the protective cover 16 is attached to the back plate of the main unit 200, and the protective cover 16 is attached to the filter mechanism 13. The protective cover 16, the main unit 200, and the filter mechanism 13 together cover the linear drive body 61 as a whole, achieving a better oil-proof effect on the linear drive body 61.

[0079] In an alternative embodiment, such as Figure 12 and Figure 13 As shown, the front connecting plate 22 also includes a first drainage section 223. The front baffle 11, the second drainage section 221, the third drainage section 222, the first drainage section 223, and the movable cavity body 21 are rotatably connected in sequence. When the linear drive mechanism 60 performs linear extension and retraction, the front connecting plate 22 with this structure can ensure that the movable cavity 20 can smoothly switch between the first position and the second position relative to the smoke collection cavity body 10.

[0080] In an alternative embodiment, such as Figure 4 , Figure 16 and Figure 19 As shown, the smoke collection space 50 of this embodiment is formed by splicing together the smoke collection cavity body 10, the movable cavity body 21, the front connecting plate 22 and the rear connecting plate 23. The smoke collection mechanism 100 with this shape involves few plate structures and has a simple structure.

[0081] In an alternative embodiment, such as Figure 4 , Figure 12 and Figure 13 As shown, the smoke collection mechanism 100 also includes a guide member 80, which is disposed on the front baffle 11. The guide member 80 is inclined downward from front to back. When the movable cavity 20 is in the first position, the guide member 80 can guide the oil on the front baffle 11 to the opening 22111, which can further improve the recovery of oil inside the smoke collection space 50 by the receiving groove 2211, and further prevent oil from flowing from the gap between the free end 2212 and the front connecting plate 22 to the outside of the oil fume treatment device 1000 and the stove, further improving the cleanliness of the kitchen and further improving the user's experience.

[0082] In an alternative embodiment, such as Figure 4 , Figure 12 and Figure 13 As shown, the smoke collection mechanism 100 also includes a second sealing component 30. When the movable cavity 20 is in the first position, the second sealing component 30 is clamped between the smoke collection cavity body 10 and the movable cavity 20, and seals the gap between the smoke collection cavity body 10 and the movable cavity 20, thereby achieving a better sealing effect on the smoke collection space 50. The oil fume odor or oil liquid accumulated inside the oil fume treatment device 1000 will not overflow from the gap between the movable cavity 20 and the smoke collection cavity body 10, ensuring a clean kitchen environment and improving the user experience.

[0083] In an alternative embodiment, such as Figure 4 and Figure 15 As shown, the movable cavity 20 also includes a front connecting plate 22, the upper end of which is rotatably connected to the smoke collection cavity body 10, and the lower end of which is rotatably connected to the movable cavity body 21. The second sealing assembly 30 also includes a first sealing member 32. When the movable cavity 20 is in the first position, the first sealing member 32 is clamped between the upper end of the front connecting plate 22 and the smoke collection cavity body 10. The first sealing member 32 can achieve a good sealing effect between the upper end of the front connecting plate 22 and the smoke collection cavity body 10 in the first position, preventing oil fumes or oil from overflowing from the gap between the upper end of the front connecting plate 22 and the smoke collection cavity body 10, ensuring a clean kitchen environment and improving the user experience.

[0084] In an alternative embodiment, such as Figure 16 and Figure 18 As shown, when the movable cavity 20 is in the second position, the first sealing member 32 is clamped between the upper end of the front connecting plate 22 and the smoke collection cavity body 10. The first sealing member 32 can achieve a better sealing effect between the upper end of the front connecting plate 22 and the smoke collection cavity body 10, reduce the air volume loss of the fume treatment device 1000, and improve the fume extraction effect of the fume treatment device 1000.

[0085] In an alternative embodiment, such as Figure 15 and Figure 18As shown, the first sealing element 32 may include a first sealing body 321 and a second sealing body 322. The first sealing body 321 is disposed on the smoke collection chamber body 10, and the second sealing body 322 is disposed on the upper end of the front connecting plate 22. When the movable cavity 20 is in the first position and the second position, the first sealing body 321 and the second sealing body 322 abut against each other. Through the cooperation of the first sealing body 321 and the second sealing body 322, a better sealing effect can be achieved on the gap between the upper end of the front connecting plate 22 and the smoke collection chamber body 10, reducing the air volume loss of the fume treatment device 1000, improving the fume extraction effect of the fume treatment device 1000, and preventing the odor of oil or oil from overflowing from the gap between the upper end of the front connecting plate 22 and the smoke collection chamber body 10, ensuring a clean kitchen environment and improving the user experience.

[0086] In an optional embodiment, the first sealing element 32 may consist only of the first sealing body 321. The first sealing body 321 is disposed on the smoke collection chamber body 10. When the movable chamber 20 is in the first position and the second position, the upper end of the front connecting plate 22 abuts against the first sealing body 321. Through the abutment of the upper end of the front connecting plate 22 against the first sealing body 321, a better sealing effect can be achieved on the gap between the upper end of the front connecting plate 22 and the smoke collection chamber body 10, reducing the air volume loss of the fume treatment device 1000, improving the fume extraction effect of the fume treatment device 1000, preventing the odor of oil or oil from overflowing from the gap between the upper end of the front connecting plate 22 and the smoke collection chamber body 10, ensuring a clean kitchen environment, and improving the user experience.

[0087] In an optional embodiment, the first sealing element 32 may only include the second sealing body 322. The second sealing body 322 is disposed at the upper end of the front connecting plate 22. When the movable cavity 20 is in the first position and the second position, the second sealing body 322 abuts against the smoke collection cavity body 10. Through the abutment of the second sealing body 322 against the smoke collection cavity body 10, a better sealing effect can be achieved between the upper end of the front connecting plate 22 and the smoke collection cavity body 10, reducing the air volume loss of the fume treatment device 1000, improving the fume extraction effect of the fume treatment device 1000, preventing the odor of oil or oil from overflowing from the gap between the upper end of the front connecting plate 22 and the smoke collection cavity body 10, ensuring a clean kitchen environment, and improving the user experience.

[0088] In an alternative embodiment, such as Figure 16 and Figure 18As shown, the first sealing body 321 includes an abutment surface 3211. When the movable cavity 20 switches between the first position and the second position, the upper end of the front connecting plate 22 or the second sealing body 322 always abuts against the abutment surface 3211. That is, no matter what state the movable cavity 20 moves to, the upper end of the front connecting plate 22 and the smoke collection cavity body 10 can always maintain a sealing effect, thereby enabling continuous and stepless adjustment of the movable cavity 20 at different positions, reducing the air volume loss of the fume treatment device 1000, and improving the fume extraction effect of the fume treatment device 1000.

[0089] For example, such as Figure 18 As shown, the shape of the abutment surface 3211 is the same as the trajectory of the upper end of the front connecting plate 22 or the trajectory of the second sealing body 322, thereby achieving the effect that the upper end of the front connecting plate 22 or the second sealing body 322 is always in contact with the abutment surface 3211. For example, the first sealing body 321 and the second sealing body 322 can be made of elastic material, thereby achieving a good sealing effect between the upper end of the front connecting plate 22 and the smoke collection chamber body 10, and also preventing damage or noise caused by hard impact between the upper end of the front connecting plate 22 and the smoke collection chamber body 10.

[0090] In an alternative embodiment, such as Figure 4 and Figure 12 As shown, the diversion component 80 is disposed on the back side 112 of the front baffle 11 and above the first sealing component 32. The diversion component 80 can block the gap between the first sealing body 321 and the second sealing body 322, which can further improve the sealing effect between the upper end of the front connecting plate 22 and the smoke collection chamber body 10. In addition, the diversion component 80 can block the gap between the first sealing body 321 and the second sealing body 322, and at least part of the diversion component 80 extends into the interior of the movable cavity 20. The diversion component 80 can also receive the oil inside the smoke collection space 50 and divert it into the interior of the movable cavity 20 and be recovered by the oil cup 300. This can prevent the oil inside the smoke collection space 50 from overflowing from the gap between the upper end of the front connecting plate 22 and the smoke collection chamber body 10, and prevent the oil from overflowing from the back side of the front baffle 11, thus ensuring the cleanliness of the oil fume treatment device 1000 and the stove below it.

[0091] In an alternative embodiment, such as Figure 1 , Figure 19 and Figure 20As shown, the second sealing assembly 30 also includes a second sealing element 33. The smoke collection chamber body 10 includes two side baffles 12 arranged in the left-right direction. The movable cavity 20 has side wall surfaces that correspond one-to-one with the corresponding side baffles 12. The second sealing element 33 is sandwiched between the side baffles 12 and their corresponding side wall surfaces. By setting the second sealing element 33, a better sealing effect can be achieved between the side baffles 12 and the smoke collection chamber body 10, reducing air volume loss and effectively improving the smoke extraction effect of the oil fume treatment device 1000. The oil fume treatment device 1000 has a better smoke extraction effect, preventing oil odors or oil from overflowing from the smoke collection space 50, ensuring a clean kitchen environment, and improving the user experience.

[0092] It should be noted that the second seal 33 can ensure the sealing effect between the side baffle 12 and the smoke collection chamber body 10 in different states of the movable cavity 20. That is, no matter what state the movable cavity 20 is in, the setting of the second seal 33 can ensure that the smoke collection space 50 always has a good sealing effect.

[0093] For example, such as Figure 1 , Figure 19 and Figure 20 As shown, the active cavity body 21 includes a first side wall 214, and a second sealing element 33 is provided on the first side wall 214. The second sealing element 33 is sandwiched between the first side wall 214 and the side baffle 12. Through the provision of the second sealing element 33, a better sealing effect can be achieved between the first side wall 214 and the side baffle 12.

[0094] For example, such as Figure 1 , Figure 19 and Figure 20 As shown, the second sealing element 33 includes a second mounting element 331 and a third sealing body 332. The third sealing body 332 extends along the extending direction of the first side wall 214. The second mounting element 331 fixes the third sealing body 332 to the movable cavity body 21, and the third sealing body 332 can seal the gap between the first side wall 214 and the movable cavity body 21. For example, the second mounting element 331 may include a mounting plate and a fixing element. The mounting plate presses the third sealing body 332 onto the movable cavity body 21, and the fixing element fixes the mounting plate, the third sealing body 332, and the movable cavity body 21 together, thereby achieving a stable clamping effect of the mounting plate and the movable cavity body 21 on the third sealing body 332. For example, the fixing element can be a screw, pin, buckle, etc. All structures that can fix the mounting plate, the third sealing body 332, and the movable cavity body 21 together are within the protection scope of this optional embodiment.

[0095] For example, such as Figure 1 , Figure 19 and Figure 20As shown, the rear connecting plate 23 includes a second side wall 231, on which a second sealing element 33 is provided. The second sealing element 33 is sandwiched between the second side wall 231 and the side baffle 12. Through the provision of the second sealing element 33, a better sealing effect can be achieved between the second side wall 231 and the side baffle 12.

[0096] For example, such as Figure 1 , Figure 19 and Figure 20 As shown, the second sealing element 33 includes a second mounting element 331 and a third sealing body 332. The third sealing body 332 extends along the extension direction of the second side wall 231. The second mounting element 331 fixes the third sealing body 332 to the rear connecting plate 23. The third sealing body 332 can seal the gap between the second side wall 231 and the rear connecting plate 23. For example, the second mounting element 331 may include a mounting plate and a fixing element. The mounting plate presses the third sealing body 332 onto the rear connecting plate 23, and the fixing element fixes the mounting plate, the third sealing body 332, and the rear connecting plate 23 together, thereby achieving a stable clamping effect of the mounting plate and the rear connecting plate 23 on the third sealing body 332. For example, the fixing element can be a screw, pin, clip, etc. All structures capable of fixing the mounting plate, the third sealing body 332, and the rear connecting plate 23 together are within the protection scope of this optional embodiment.

[0097] For example, such as Figure 20 As shown, the third sealing body 332 can be made of an elastic material, thereby achieving a consistently good sealing effect on the gap between the movable cavity 20 and the smoke collection cavity body 10 in the left-right direction. The elastic material can be rubber, silicone, etc., and all materials with elastic deformation properties are within the protection scope of this optional embodiment.

[0098] In an alternative embodiment, such as Figure 4 and Figure 15 As shown, the smoke collection chamber body 10 includes a front baffle 11 and a sealing member 14 disposed on its back side. The second sealing assembly 30 includes a fourth sealing member 31. When the movable chamber 20 is in the first position, the fourth sealing member 31 is clamped between the sealing member 14 and the movable chamber body 21. The fourth sealing member 31 can achieve a better sealing effect between the movable chamber body 21 and the sealing member 14, preventing oil fumes or oil from overflowing from the gap between the movable chamber body 21 and the sealing member 14, ensuring a clean kitchen environment and improving the user experience.

[0099] In an alternative embodiment, such as Figure 4 and Figure 15As shown, the sealing member 14 includes a clamping surface 141, and the movable cavity body 21 includes an upper end plate 213. The clamping surface 141 is located above the upper end plate 213. The fourth sealing member 31 is clamped by the clamping surface 141 and the upper end plate 213. The clamping surface 141 and the upper end plate 213 can achieve tight clamping of the fourth sealing member 31, thereby sealing the gap between the sealing member 14 and the movable cavity body 21.

[0100] In an alternative embodiment, such as Figure 4 and Figure 15 As shown, the fourth sealing element 31 includes a sealing element body 311 connected to the sealing element and a second conical insertion part 312. The clamping surface 141 is provided with a second insertion interface 1411, and the second conical insertion part 312 is inserted into the second insertion interface 1411, thereby enabling quick installation and stable locking of the second conical insertion part 312 and the second insertion interface 1411. The insertion of the second conical insertion part 312 into the second insertion interface 1411 enables a stable connection between the fourth sealing element 31 and the sealing element 14, and enables a good sealing effect between the movable cavity body 21 and the sealing element 14.

[0101] In an optional embodiment, a second insertion interface 1411 can be provided on the movable cavity body 21, and the second conical insertion part 312 can be inserted into the second insertion interface 1411, which can also achieve the above-mentioned effect.

[0102] In an alternative embodiment, such as Figure 4 and Figure 15 As shown, the fourth sealing element 31 can be made of an elastic material, thereby achieving a consistently good sealing effect between the sealing element 14 and the movable cavity body 21, and preventing damage or noise caused by hard impacts between the sealing element 14 and the movable cavity body 21. For example, the elastic material can be silicone, rubber, etc., and all materials with elastic deformation properties are within the protection scope of this optional embodiment, which will not be listed one by one.

[0103] Since the movable cavity 20 can move relative to the smoke collection chamber body 10, there is a gap between the movable cavity 20 and the smoke collection chamber body 10. When the movable cavity 20 is in the second position, the presence of the gap results in poor sealing of the smoke collection space 50, which will cause a large loss of air volume, resulting in a significant reduction in the smoke extraction effect of the oil fume treatment device 1000. The oil fume treatment device 1000 has a poor smoke extraction effect.

[0104] To solve the above problems, such as Figure 16As shown, this embodiment of the present disclosure provides an oil fume treatment device 1000, which includes a smoke collection mechanism 100. The smoke collection mechanism 100 includes a smoke collection chamber body 10, a movable cavity 20, and a third sealing member 70. The movable cavity 20 has an air inlet 211 and together with the smoke collection chamber body 10, forms a smoke collection space 50. The movable cavity 20 can switch between a first position where it is housed in the smoke collection chamber body 10 and a second position where it extends out of the smoke collection chamber body 10. When the movable cavity 20 is in the second position, the third sealing member 70 is disposed between the smoke collection chamber body 10 and the movable cavity 20, and seals the gap between the smoke collection chamber body 10 and the movable cavity 20, effectively improving the sealing performance of the smoke collection space 50, reducing airflow loss, and effectively improving the oil fume extraction effect of the oil fume treatment device 1000. The oil fume treatment device 1000 has a good oil fume extraction effect. It should be noted that when the movable cavity 20 is in the second position, the movable cavity 20 can extend downward relative to the smoke gathering cavity body 10, or the movable cavity 20 can extend forward and downward relative to the smoke gathering cavity body 10.

[0105] In an alternative embodiment, such as Figure 16 and Figure 17 As shown, the smoke collection chamber body 10 includes a front baffle 11. When the movable chamber 20 is in the second position, the third sealing member 70 is clamped between the front baffle 11 and the movable chamber body 21. The third sealing member 70 can achieve a better sealing effect between the movable chamber body 21 and the front baffle 11, reduce the air volume loss of the oil fume treatment device 1000, and improve the oil fume extraction effect of the oil fume treatment device 1000.

[0106] In an alternative embodiment, such as Figure 16 and Figure 17 As shown, the third sealing element 70 is disposed on the movable cavity body 21. The front baffle 11 includes a bottom surface 111 and a back surface 112. The third sealing element 70 includes a front side surface 711 and an upper side surface 712. When the movable cavity body 20 is in the second position, the bottom surface 111 abuts against the upper side surface 712, and the back surface 112 abuts against the front side surface 711. The third sealing element 70 can achieve a better sealing effect on the movable cavity body 21 and the front baffle 11 in different positions and dimensions, thereby achieving a better sealing effect of the third sealing element 70 on the gap between the movable cavity body 21 and the front baffle 11, reducing the air volume loss of the fume treatment device 1000, and improving the fume extraction effect of the fume treatment device 1000.

[0107] In an alternative embodiment, such as Figure 16 and Figure 17As shown, the third seal 70 can be made of an elastic material. On the one hand, the third seal 70 has a certain degree of elasticity, which can prevent hard impact or hard contact between the movable cavity body 21 and the front baffle 11, avoid damage to the movable cavity body 21 and the front baffle 11, and also avoid the large noise generated by the collision between the movable cavity body 21 and the front baffle 11. On the other hand, since the third seal 70 has a certain amount of elastic deformation, it can allow for a certain installation error between the movable cavity body 21 and the front baffle 11, and the corresponding installation error can be compensated by the elastic deformation of the third seal 70. For example, the third seal 70 can be rubber, silicone, etc., and all materials with elastic deformation are within the protection scope of this optional embodiment.

[0108] In an alternative embodiment, such as Figure 16 and Figure 17 As shown, the third seal 70 and the movable cavity body 21 can be fixedly connected by an adhesive layer or a snap-fit ​​structure, etc. All structures that can achieve a stable connection between the third seal 70 and the movable cavity body 21 are within the protection scope of this optional embodiment.

[0109] For example, such as Figure 17 As shown, the third sealing element 70 includes a sealing part 71 and a first conical insertion part 72 disposed thereon. The movable cavity body 21 is provided with a first insertion interface 215. The first conical insertion part 72 is inserted into the first insertion interface 215, thereby enabling quick installation and stable locking of the first conical insertion part 72 and the first insertion interface 215. The insertion of the first conical insertion part 72 into the first insertion interface 215 enables a stable connection between the third sealing element 70 and the movable cavity body 21, reducing the air volume loss of the fume treatment device 1000 and improving the fume extraction effect of the fume treatment device 1000.

[0110] In an alternative embodiment, such as Figure 16 and Figure 17 As shown, the third sealing element 70 also includes a lower side surface 713. The upper side surface 712 and the lower side surface 713 are spaced apart in the vertical direction. This spacing can prevent the cabinet door of the cabinet 2000 from sag and colliding with the movable cavity 20 due to long-term use. For example, the distance between the upper side surface 712 and the lower side surface 713 in the vertical direction is 5mm to 15mm, which can effectively prevent the movable cavity 20 from bumping against the drooping cabinet door.

[0111] In an alternative embodiment, such as Figure 17As shown, the third sealing element 70 can also be set on the smoke collection chamber body 10. The movable chamber body 21 includes a front side plate 212 and an upper end plate 213. When the movable chamber body 20 is in the second position, the third sealing element 70 includes a lower side surface 713 and a back side surface 714. The lower side surface 713 abuts against the upper end plate 213, and the back side surface 714 abuts against the front side plate 212. The setting of the third sealing element 70 can achieve a better sealing effect on the movable chamber body 21 and the front baffle 11 at different positions and in various dimensions, thereby achieving a better sealing effect of the third sealing element 70 on the gap between the movable chamber body 21 and the front baffle 11, reducing the air volume loss of the fume treatment device 1000, and improving the fume extraction effect of the fume treatment device 1000.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
