[0063] The technical solutions of the present invention will be further described below in conjunction with the drawings and implementation modes. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all of them.

[0064] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0065] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0066] In the description of the embodiments of the present disclosure, the orientation or positional relationships such as "upper", "lower", "left" and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0067] As Figures 1 - 2 shown, the embodiments of the present disclosure provide an oil fume treatment device 100. The oil fume treatment device 100 includes a main chassis (not shown in the figure) and a smoke collecting cavity assembly that are connected and communicated. Among them, a fan main chassis is arranged in the main chassis. The smoke collecting cavity assembly has an air inlet 511. When the main chassis is working, the oil fume outside the oil fume treatment device 100 can enter from the air inlet 511. The oil fume sequentially passes through the smoke collecting cavity assembly and the main chassis. The oil fume is purified in the main chassis, and the purified gas is discharged from the air outlet (not shown in the figure) of the main chassis to an external pipeline or the indoor.

[0068] In the prior art, the smoke collecting cavity assembly includes a housing 20, a flap assembly 30, an air inlet plate 50, a first driving device and a second driving device. Among them, the flap assembly 30 includes a first flap 31 and a second flap 32. The first driving device can drive the flap assembly 30 to switch between an open state and a closed state. When the flap assembly 30 is in the open state, the flap assembly 30 can achieve a good gathering effect on the oil fume, and the flap assembly 30 can guide a large amount of oil fume to enter the main chassis well. The air inlet 511 is opened on the air inlet plate 50. The second driving device can drive the air inlet plate 50 to switch between an open state and a closed state. When the air inlet plate 50 is in the open state, the air inlet 511 is closer to the oil fume, so that the smoke collecting cavity assembly can achieve a good absorption effect on the oil fume. When the first driving device and the second driving device work synchronously, the synchronous opening or synchronous closing of the flap assembly 30 and the air inlet plate 50 can be achieved.

[0069] However, it should be noted that the first driving device and the flap assembly 30 are drivingly connected through a complex first transmission assembly, and the second driving device and the air inlet plate 50 are drivingly connected through a relatively complex second transmission assembly. Therefore, in the prior art, the smoke collecting cavity assembly has more driving devices, and the transmission assembly in the smoke collecting cavity assembly has a complex structure and a large volume, resulting in poor oil fume absorption effect, complex structure, difficult assembly, large volume and easy jamming of the existing smoke collecting cavity assembly.

[0070] To solve the above problems, as Figures 1 - 3 shown, the oil fume treatment device 100 further includes a linear driving mechanism 40, a guiding assembly 10 and a transmission assembly 60. Among them, the housing 20 is rotatably connected to the first flap 31. The guiding assembly 10 includes a fixing mechanism 11 and a sliding mechanism 12 slidably disposed thereon. The fixing mechanism 11 is disposed on the first flap 31. One end of the linear driving mechanism 40 is rotatably connected to the housing 20, and the other end of the linear driving mechanism 40 is rotatably connected to the first flap 31. One end of the air inlet plate 50 is rotatably connected to the housing 20, and the other end of the air inlet plate 50 is rotatably connected to the sliding mechanism 12. The transmission assembly 60 is rotatably connected to the first flap 31 and the sliding mechanism 12 respectively, and the transmission assembly 60 is fixedly connected to the second flap 32. When the linear driving mechanism 40 works, the linear driving mechanism 40 can drive the first flap 31 to rotate relative to the housing 20. The rotation of the first flap 31 can cause the sliding mechanism 12 to slide relative to the fixing mechanism 11. Under the combined action of the rotation of the first flap 31 and the sliding of the sliding mechanism 12, the air inlet plate 50 can be rotated around the housing 20, and the air inlet plate 50 rotates relative to the first flap 31 and cooperates with the sliding; at the same time, the sliding of the sliding mechanism 12 relative to the fixing mechanism 11 can cause relative movements and relative position changes of the various parts of the transmission assembly 60, and the transmission assembly 60 can realize the rotation of the second flap 32 relative to the first flap 31. In summary, through the rotation of the first flap 31 driven by the linear driving mechanism 40, the rotation of the air inlet plate 50 relative to the housing 20 and the first flap 31, and the rotation of the second flap 32 relative to the first flap 31 can be triggered simultaneously. That is to say, the rotation of the linear driving mechanism 40 can realize the linkage of the rotation of the first flap 31 relative to the housing 20, the rotation of the air inlet 50 relative to the housing 20 and the first flap 31, and the rotation of the second flap 32 relative to the first flap.

[0071] The oil fume treatment device 100 of the present disclosure embodiment can realize the synchronous opening or synchronous closing of the first flap 31, the second flap 32 and the air inlet plate 50 only by setting a set of linear driving mechanism 40 and in cooperation with the guiding assembly 10 and the transmission assembly 60. Compared with the oil fume treatment device 100 in the prior art, the oil fume treatment device 100 of the present disclosure embodiment has the advantages of simple structure, easy assembly, small volume, not easy to jam and better oil fume absorption effect.

[0072] Specifically, when the oil fume treatment device 100 is required to be in an open state, the oil fume treatment device 100 is Figure 3 The status switches to Figure 2 In the state, the push rod of the linear drive mechanism 40 extends out, and the push rod pushes the first flap 31, so that the first flap 31 is flipped outward clockwise relative to the shell 20; the outward flipping of the first flap 31 can drive the air inlet plate 50 to flip outward counterclockwise relative to the shell 20, and the flipping movement of the air inlet plate 50 can make the sliding mechanism 12 slide downward relative to the fixing mechanism 11; the sliding of the sliding mechanism 12 drives the various parts of the transmission assembly 60 to undergo relative movement and relative position change, and also causes the transmission assembly 60 to rotate relative to the first flap 31, and the transmission assembly 60 drives the second flap 32 to rotate clockwise relative to the first flap 31 to open, and only by driving the linear drive mechanism 40 alone, the first flap 31, the second flap 32 and the air inlet plate 50 can be synchronously and quickly opened. Similarly, when the oil fume treatment device 100 is required to be in a closed state, the oil fume treatment device 100 is opened from Figure 2 The status switches to Figure 3 The state of the related structure is opposite to the above-mentioned action mode.

[0073] In an optional embodiment, if Figures 2 - 8 As shown, the sliding mechanism 12 includes a first sliding member 121 and a second sliding member 122 that are fixedly connected, the first sliding member 121 is rotatably connected to the air inlet plate 50, and the second sliding member 122 is rotatably connected to the transmission assembly 60. By setting the sliding mechanism 12 as two independent modules, in which the first sliding member 121 is connected to the air inlet plate 50, and the second sliding member 122 is connected to the transmission assembly 60, it is possible to facilitate the rapid installation of the air inlet plate 50 and the transmission assembly 60 with the sliding mechanism 12, and avoid interference between different structures when installing the air inlet plate 50 and the transmission assembly 60 with the sliding mechanism 12.

[0074] In addition, if Figure 8 As shown, the first sliding member 121 and the second sliding member 122 can be spliced ​​to form a corresponding special-shaped sliding mechanism 12 according to the overall structural setting of the oil fume treatment device 100, further improving the flexibility of the sliding mechanism 12 to be connected to the air inlet plate 50 and the transmission assembly 60 respectively. In addition, the first sliding member 121 and the second sliding member 122 can be assembled with existing standard parts to form a special-shaped sliding mechanism 12 suitable for the oil fume treatment device 100 of the embodiment of the present disclosure, which can improve the production efficiency of the sliding mechanism 12, and can effectively reduce the injection molding production line opened separately for the separate production of the special-shaped sliding mechanism 12, effectively reduce the production cost of the sliding mechanism 12, and thus effectively reduce the production cost of the oil fume treatment device 100.

[0075] In an alternative embodiment, as Figure 8 shown, the first sliding member 121 and the second sliding member 122 are in concave-convex fit, which can effectively improve the installation efficiency and installation accuracy of the first sliding member 121 and the second sliding member 122, and can realize the rapid assembly of the sliding mechanism 12. In addition, through the concave-convex fit of the first sliding member 121 and the second sliding member 122, the separation of the first sliding member 121 and the second sliding member 122 caused by the long-term force on the sliding mechanism 12 can be avoided, ensuring the long-term good use stability of the sliding mechanism 12.

[0076] In an alternative embodiment, as Figure 8 shown, the first sliding member 121 includes a sliding member main body 1211 and two limiting portions 1213, and the two limiting portions 1213 are arranged on both sides of the sliding member main body 1211; the second sliding member 122 includes a fixing member 1221 and two rotating connecting members 1222, the fixing member 1221 is fixedly connected to the first sliding member 121, the rotating connecting member 1222 is rotatably connected to the transmission assembly 60 at the connection position P, and the two rotating connecting members 1222 are arranged on both sides of the fixing member 1221; wherein, the sliding member main body 1211 is attached to and fixedly connected to the fixing member 1221, and each limiting portion 1213 is attached to and fixedly connected to the corresponding rotating connecting member 1222, and through the surface attachment and fixed connection at multiple positions, the stable connection of the first sliding member 121 and the second sliding member 122 in all directions is realized.

[0077] Exemplarily, the first sliding member 121 and the second sliding member 122 can be fixedly connected by fasteners such as screws, pins, magnetic attraction structures, snap components, etc. On the one hand, the stable connection of the first sliding member 121 and the second sliding member 122 can be realized, and the first sliding member 121 and the second sliding member 122 will not become loose and separated; on the other hand, the rapid disassembly and assembly of the first sliding member 121 and the second sliding member 122 can also be realized.

[0078] In an alternative embodiment, as Figure 8 shown, a recessed portion 1212 is provided on the sliding member main body 1211, and the fixing member 1221 includes a fixing member main body 12211 and a protruding portion 12212 provided thereon. Since the overall areas of the sliding member main body 1211 and the fixing member 1221 are large, a relatively large recessed portion 1212 and a protruding portion 12212 can be provided, and the relatively large recessed portion 1212 and protruding portion 12212 can achieve a better limiting effect between the first sliding member 121 and the second sliding member 122.

[0079] In addition, since the bottom surface of the recessed portion 1212 and as Figure 2The end face of the fixing mechanism 11 shown is cooperated to achieve guiding. Therefore, after the thickness of the fixing mechanism 11 is determined, the position of the bottom surface of the recess 1212 is fixed. If the recess 1212 is not provided on the slider body 1211, it will cause the bottom surface of the slider body 1211 to be Figure 8 flush with the bottom surface of the recess 1212 of Figure 2 shown, which will result in a smaller height of the limiting portion 1213, and thus a smaller effective contact dimension in the height direction between the limiting portion 1213 and its corresponding rotating connecting member 1222. Therefore, it is not convenient to effectively fix the limiting portion 1213 and the rotating connecting member 1222 through fasteners. By providing the recess 1212, on the premise of ensuring effective contact between the bottom surface of the recess 1212 and the

[0080] As Figure 9 shown, the rotating connecting member 1222 and the transmission assembly 60 are rotatably connected at the connection position P. Among them, along the width direction of the oil fume treatment device 100, both the rotating connecting member 1222 and the transmission assembly 60 are located outside the first slider 121. The rotating connecting member 1222, the first slider 121 and the transmission assembly 60 together form a receiving space 70. The connection position P is located in the receiving space 70. Part of the air inlet plate 50 can move in the receiving space 70. Through the foregoing arrangement, it is possible to ensure the compact arrangement of the rotating connecting member 1222, the first slider 121, the transmission assembly 60 and the air inlet plate 50, reasonably reduce the space occupied by the foregoing structure as a whole, realize the reasonable arrangement of the rotating connecting member 1222, the first slider 121, the transmission assembly 60 and the air inlet plate 50 in a limited space, and also avoid interference between the foregoing parts during movement and avoid jamming problems during the movement of the foregoing parts.

[0081] In an alternative embodiment, the guiding assembly 10 can be set to two groups, and the two groups of guiding assemblies 10 are arranged at intervals along the width direction of the oil fume treatment device 100. Through the joint setting of the two groups of guiding assemblies 10, the synchronism of the rotation of the air inlet plate 50 relative to the first flap 31 at each position in the width direction of the air inlet plate 50 can be realized, and interference or jamming between the air inlet plate 50 and the first flap 31 can be avoided. In addition, the synchronism of the rotation of the second flap 32 relative to the first flap 31 at each position in the width direction of the second flap 32 can also be realized, and interference or jamming between the second flap 32 and the first flap 31 can be avoided.

[0082] Of course, in other alternative embodiments, the guiding component 10 can also be provided in one group, three groups, four groups or more groups, and the number of the guiding components 10 can be adjusted according to the specific size of the first flap 31.

[0083] As Figure 8 shown, two rotating connectors 1222 are provided. Along the width direction of the oil fume treatment device 100, the two rotating connectors 1222 are located on both sides of the fixing member 1221. When the transmission component 60 is arranged on the left side of the air inlet plate 50, the transmission component 60 is rotatably connected to the rotating connector 1222 on the left side; when the transmission component 60 is arranged on the right side of the air inlet plate 50, the transmission component 60 is rotatably connected to the rotating connector 1222 on the right side. That is to say, by manufacturing a unified type of the second sliding member 122, the setting and installation of the second sliding member 122 at different positions can be realized, the processing cost of the second sliding member 122 can be effectively reduced, and the types of the overall components of the entire oil fume treatment device 100 can be reduced.

[0084] In an alternative embodiment, as Figure 7 shown, the rotating connector 1222 includes a connecting arm 12221 and a connecting block 12222. Wherein, one end of the connecting arm 12221 is fixedly connected to the fixing member 1221, the other end of the connecting arm 12221 is fixedly connected to the connecting block 12222, the transmission component 60 is rotatably connected to the connecting block 12222, and the connecting block 12222 has high structural strength and hardness, so the connecting block 12222 can achieve a stable supporting effect relative to the transmission component 60.

[0085] In an alternative embodiment, as Figure 7 shown, the connecting block 12222 is provided with a plugging slot 122221, the transmission component 60 is plugged into the plugging slot 122221 and is rotatably connected to the connecting block 12222 through a rotating shaft, so as to achieve a relatively stable connection effect between the connecting block 12222 and the transmission component 60. Exemplarily, rotating shafts are arranged on both sides of the transmission component 60, each rotating shaft is rotatably connected to the wall of the corresponding plugging slot 122221, and the two rotating shafts are respectively supported by the connecting block 12222, so as to achieve a stable supporting effect of the connecting block 12222 on the transmission component 60.

[0086] Exemplarily, as Figure 7 shown, the structure of the second sliding member 122 is relatively complex, and the second sliding member 122 can be integrally formed by injection molding, extrusion molding, casting molding and other methods, so as to improve the processing and forming efficiency of the second sliding member 122.

[0087] In an alternative embodiment, as Figure 2 、 Figure 3 and Figure 10As shown, the housing 20 includes a front plate 21, a back plate 22, and side baffles 24. Among them, the front plate 21 and the back plate 22 are arranged at intervals in the front-rear direction. The side baffles 24 are disposed between the front plate 21 and the back plate 22. An air inlet 211 is formed on the front plate 21, and the air inlet 211 is communicated with the air inlet 511. The front plate 21, the side baffles 24, and the back plate 22 together form a first sound-absorbing cavity 23. The first sound-absorbing cavity 23 can preliminarily isolate and absorb the noise generated by the main chassis, reduce the noise generated by the main chassis received by the user, and further improve the user's experience of using the oil fume treatment device 100.

[0088] In an alternative embodiment, as Figures 1 - 3 shown, the oil fume treatment device 100 further includes an oil mesh 90. The oil mesh 90 is disposed on the air inlet 211. By providing the oil mesh 90, the filtering effect on the oil fume can be further improved.

[0089] In an alternative embodiment, as Figure 2 and Figure 10 shown, the first flap 31 includes a first flap body 311 and two first side plates 312 disposed thereon. The two first side plates 312 are arranged at intervals in the width direction of the first flap body 311. When the flap assembly 30 is in the open state, the first flap body 311, the first side plates 312, the front plate 21, and the air inlet plate 50 together form a second sound-absorbing cavity 80. By providing the second sound-absorbing cavity 80, the isolation effect on the noise generated by the main chassis can be further enhanced, the noise generated by the main chassis received by the user can be further reduced, and the user's experience of using the oil fume treatment device 100 can be further improved. Through the mutual cooperation of the first sound-absorbing cavity 23 and the second sound-absorbing cavity 80, the noise generated by the main chassis received by the user can be effectively reduced, and the user's experience of using the oil fume treatment device 100 can be effectively improved.

[0090] In an alternative embodiment, as Figure 2 and Figure 10 shown, the setting of the first side plates 312 can prevent the oil fume from overflowing from both sides of the first flap 31, thereby further improving the oil fume absorption effect of the oil fume treatment device 100.

[0091] In an alternative embodiment, the air inlet 511 is in a long strip shape and extends along the width direction of the oil fume treatment device 100. The setting of the flat and long air inlet 511 can further prevent the noise generated by the main chassis from being transmitted outward, further reduce the noise generated by the main chassis received by the user, and further improve the user's experience of using the oil fume treatment device 100.

[0092] As Figure 1 and Figure 9As shown, the first side plate 312 includes a first side plate body 3121 and a sealing plate 3122. The first side plate body 3121 is fixedly connected to the first flap body 311. Along the width direction of the oil fume treatment device 100, the air inlet plate 50 and the first side plate body 3121 are located on both sides of the transmission assembly 60. The sealing plate 3122 is disposed in the gap between the air inlet plate 50 and the first side plate body 3121. On the one hand, it can prevent the formation of a slit that may pinch the user's finger. On the other hand, the sealing plate 3122 can also prevent the oil fume from contaminating the transmission assembly 60, ensuring that the transmission assembly 60 always has a good cleanliness.

[0093] As Figure 2 , Figure 3 and Figure 9 shown, the air inlet plate 50 includes an air inlet plate body 51 and a second side plate 52 disposed thereon. The air inlet 511 is provided on the air inlet plate body 51. Along the width direction of the oil fume treatment device 100, the transmission assembly 60 and the air inlet 511 are located on both sides of the second side plate 52. The second side plate 52 can block a part of the oil fume entering from the air inlet 511 and hitting the transmission assembly 60, which can further prevent the oil fume from contaminating the transmission assembly 60 and ensure that the transmission assembly 60 always has a good cleanliness.

[0094] In an alternative embodiment, as Figure 2 , Figure 3 and Figure 10 shown, the transmission assembly 60 includes a first connecting rod 61 and a second connecting rod 62. One end of the first connecting rod 61 is rotatably connected to the sliding mechanism 12. The second connecting rod 62 is respectively rotatably connected to the first flap 31 and the other end of the first connecting rod 61. The second connecting rod 62 is fixedly connected to the second flap 32. The design of the transmission assembly 60 with the above structure is simple and convenient for assembly. As Figure 2 shown, when the flap assembly 30 is in the open state, the first flap 31, the first connecting rod 61, and the second connecting rod 62 form a triangular structure. The overall shape of the triangular structure is relatively stable, and the triangular structure can achieve a stable supporting effect relative to the second flap 32.

[0095] In an alternative embodiment, as Figures 11 - 14As shown, the first flap 31 includes a panel 3111, a lining plate 3112, and a reinforcing member 3113. The lining plate 3112 is disposed on the back side of the panel 3111 and fixedly connected to the panel 3111. The reinforcing member 3113 is jointly clamped by the panel 3111 and the lining plate 3112. The fixing mechanism 11 is fixedly connected to the lining plate 3112 and the reinforcing member 3113. By providing the reinforcing member 3113, the strength and hardness of the first flap 31 can be effectively enhanced, and a firm connection between the first flap 31 and the fixing mechanism 11 can be achieved, avoiding deformation of the first flap 31 during long-term use and ensuring the smooth movement of each part of the oil fume treatment device 100. Exemplarily, the reinforcing member 3113 can be a structure with relatively high strength and hardness such as a stainless steel plate, a copper plate, or an aluminum plate.

[0096] Specifically, the panel 3111 and the lining plate 3112 can be fixed to the fixing mechanism, and the fixing mechanism can achieve the fixed connection between the panel 3111 and the lining plate 3112. Among them, the fixing mechanism can be at least one of an adhesive layer, a pin, a screw, a snap component, and a magnetic attraction component.

[0097] In an alternative embodiment, as Figure 12 and Figure 13 shown, one of the panel 3111 and the lining plate 3112 includes a limiting body 31125, and the limiting body 31125 cooperates with the other one to define the relative position between the panel 3111 and the lining plate 3112, enabling rapid and accurate positioning of the panel 3111 and the lining plate 3112, and achieving a rapid and accurate assembly effect between the panel 3111 and the lining plate 3112.

[0098] In an alternative embodiment, as Figures 11 - 14 shown, the lining plate 3112 has a first accommodation groove 31121, the notch of the first accommodation groove 31121 is arranged facing the panel 3111, and the reinforcing member 3113 is disposed in the first accommodation groove 31121. The reinforcing member 3113 is only provided at the position where the first flap 31 installs the guiding component 10. On the premise of ensuring the stable installation of the guiding component 10, it can also avoid the first flap 31 from being too heavy and ensure a good flipping effect of the first flap 31. In addition, through the provision of the first accommodation groove 31121, the installation efficiency and installation accuracy of the reinforcing member 3113 and the lining plate 3112 can be effectively improved. In addition, since the first accommodation groove 31121 protrudes on the back of the lining plate 3112, it is convenient for operators to quickly identify and position, and can improve the installation efficiency and installation accuracy of the guiding component 10 and the first flap 31.

[0099] In an alternative embodiment, as Figures 11 - 14As shown, the first flap 31 also includes a first mounting seat 313, and the first mounting seat 313 includes a first connecting plate 3131 and a first mounting plate 3132. A mounting opening 31122 is opened on the lining plate 3112, and the first connecting plate 3131 is clamped between the panel 3111 and the lining plate 3112. The first mounting plate 3132 extends through the mounting opening 31122 to the side of the lining plate 3112 away from the panel 3111. The first connecting plate 3131 is clamped between the panel 3111 and the lining plate 3112, so as to achieve a firm connection between the first connecting plate 3131 and the panel 3111 and the lining plate 3112 respectively, thereby preventing the first mounting seat 313 from falling off the lining plate 3112.

[0100] In an optional embodiment, if Figures 11 - 14 As shown, a second receiving groove 31123 is provided on the lining plate 3112, the groove opening of the second receiving groove 31123 is arranged toward the panel 3111, the installation opening 31122 is provided on the groove bottom surface of the second receiving groove 31123, and the first connecting plate 3131 is accommodated in the second receiving groove 31123. Through the setting of the second receiving groove 31123, the installation efficiency and installation accuracy of the first mounting seat 313 and the lining plate 3112 can be effectively improved.

[0101] In an optional embodiment, if Figures 11 - 14 As shown, the lining plate 3112 includes a first limiting structure, and the first connecting plate 3131 is provided with a second limiting structure. The first limiting structure and the second limiting structure cooperate with each other to achieve a quick positioning effect of the first connecting plate 3131 and the lining plate 3112, thereby improving the assembly efficiency and assembly accuracy of the lining plate 3112 and the first connecting plate 3131. For example, Figures 11 - 14 As shown, the first limiting structure can be a limiting hole 31124 opened on the bottom surface of the second accommodating groove 31123, and the second limiting structure can be a limiting member 3133 set on the first connecting plate 3131. The concave-convex matching of the first limiting structure and the second limiting structure is achieved through the plug-in matching of the limiting hole 31124 and the limiting member 3133. Of course, in other embodiments, the first limiting structure can also be a limiting member and the second limiting structure can be a limiting hole, which can also achieve the above effect.

[0102] In an optional embodiment, if Figure 3As shown, when the flap assembly 30 is in the closed state, the extension direction of the linear drive mechanism 40 is perpendicular to the first flap 31. When the flap assembly 30 is in the closed state, the first flap 31 is only subjected to the backward pulling force of the linear drive mechanism 40, which can prevent the first flap 31 from receiving the upward or downward force, and can ensure the accuracy of the position of the first flap 31 when it is in the closed state, and avoid the first flap 31 from being tilted due to the upward or downward external force, and avoid damage to the first flap 31. It can also avoid the overflow of the oil fume treatment device 100 caused by a large gap between the first flap 31 and the second flap 32, and avoid the exposure of the internal structure of the oil fume treatment device 100 due to the large gap between the first flap 31 and the second flap 32, thereby ensuring the good appearance of the oil fume treatment device 100 in the closed state.

[0103] In the prior art, the smoke collecting chamber assembly includes a shell 20, a flap assembly 30 and a linear drive mechanism 40. When the flap assembly 30 is in a closed state, the force applied by the linear drive mechanism 40 to the flap assembly 30 will have an upward or downward component, which will cause the flap assembly 30 to be unable to be in a tightly closed state, resulting in a large gap between the flap assembly 30 and the shell 20. On the one hand, the oil fume smell inside the oil fume treatment device 100 will overflow, affecting the cleanliness of the kitchen environment and the user's experience; on the other hand, the gap between the flap assembly 30 and the shell 20 will also cause the internal structure of the oil fume treatment device 100 to be exposed, and it is impossible to ensure a good appearance of the oil fume treatment device 100 in the closed state; thirdly, it will also cause damage to the flap assembly 30.

[0104] In order to solve the above problems, Figures 2 - 4 As shown, the linear drive mechanism 40 includes a driving body 41 and an output end 42. The output end 42 can make linear motion relative to the driving body 41. The driving body 41 is transmission-connected to the housing 20. The output end 42 is transmission-connected to the flap assembly 30. When the flap assembly 30 is in a closed state, the extension direction of the output end 42 is perpendicular to the flap assembly 30.

[0105] like Figure 3As shown, when the flap assembly 30 is in the closed state, the extending direction of the linear drive mechanism 40 is perpendicular to the flap assembly 30. When the flap assembly 30 is in the closed state, the flap assembly 30 is only subjected to the backward pulling force of the linear drive mechanism 40, which can avoid the flap assembly 30 receiving upward or downward component forces, ensure the accuracy of the position of the flap assembly 30 when it is in the closed state, avoid the position deviation of the flap assembly 30 caused by upward or downward external forces, avoid damage to the flap assembly 30, and also avoid the overflow of the internal oil fume smell of the oil fume treatment device 100 caused by a large gap between the flap assembly 30 and the housing 20. It can also avoid the exposure of the internal structure of the oil fume treatment device 100 due to the large gap between the flap assembly 30 and the housing 20, and ensure the good appearance of the oil fume treatment device 100 in the closed state.

[0106] In an alternative embodiment, as Figures 2 - 6 shown, the flap assembly 30 includes a first flap 31. The first flap 31 includes a first flap body 311 and a first mounting seat 313 provided thereon. The first flap body 311 can rotate relative to the housing 20, and the first mounting seat 313 is rotatably connected to the output end 42 through a first rotational connection position M1; the housing 20 includes a housing body and a second mounting seat 25 provided thereon, and the driving body 41 is rotatably connected to the second mounting seat 25 through a second rotational connection position M2; when the flap assembly 30 is in the closed state, the connecting line M1M2 between the first rotational connection position M1 and the second rotational connection position M2 is perpendicular to the first flap body 311. Through a simple structural arrangement, when the flap assembly 30 is in the closed state, the extending direction of the linear drive mechanism 40 is perpendicular to the flap assembly 30.

[0107] In an alternative embodiment, as Figure 2 、 Figure 3 and Figure 5 shown, the first mounting seat 313 includes a first connecting plate 3131 and a first mounting plate 3132. Among them, the first connecting plate 3131 is connected to the flap assembly 30, the first mounting plate 3132 is connected to the first connecting plate 3131, and the output end 42 is rotatably connected to the first mounting plate 3132. By the surface contact between the first connecting plate 3131 and the flap assembly 30, a firm connection between the first connecting plate 3131 and the flap assembly 30 can be achieved.

[0108] Exemplarily, the first connecting plate 3131 and the flap assembly 30 can be fixedly connected through various first fixing structures such as pins, screws, snap components, magnetic attraction components, etc. All structures that can achieve a firm connection between the first connecting plate 3131 and the flap assembly 30 are within the protection scope of the embodiments of the present disclosure.

[0109] Exemplarily, the number of the first fixing structures may be one, two, three or more. When there is one first fixing structure, the installation process of the first mounting seat 313 and the flap assembly 30 can be simplified. When there are at least two first fixing structures, a stable connection between the first connecting plate 3131 and the flap assembly 30 can be achieved.

[0110] In an optional embodiment, if Figure 5 As shown, there are two first mounting plates 3132, and the two first mounting plates 3132 are arranged at intervals along the width direction of the oil fume treatment device 100. The output end 42 is arranged between the two first mounting plates 3132, and the output end 42 is rotatably connected to the first mounting plate 3132 through the first rotating shaft. Through the arrangement of the two first mounting plates 3132, a stable support relative to the first rotating shaft can be realized, and a better rotation connection effect between the output end 42 and the first mounting seat 313 can be guaranteed.

[0111] In an optional embodiment, if Figure 6 As shown, the second mounting seat 25 includes a second connecting plate 251 and a second mounting plate 252. The second connecting plate 251 is connected to the outer shell body, and the second mounting plate 252 is connected to the second connecting plate 251. The driving body 41 is rotatably connected to the second mounting plate 252. The second connecting plate 251 abuts against the surface of the outer shell body, so that a stable connection between the second connecting plate 251 and the outer shell body can be achieved.

[0112] Exemplarily, the second connecting plate 251 and the shell body can be fixedly connected by a second fixing structure in various forms such as pins, screws, snap assemblies, magnetic assemblies, etc. All structures that can achieve a stable connection between the second connecting plate 251 and the shell body are within the protection scope of the embodiments of the present disclosure.

[0113] Exemplarily, the number of the second fixing structures can be one, two, three or more. When there is one second fixing structure, the installation process of the second mounting seat 25 and the housing body can be simplified. When there are at least two second fixing structures, a stable connection between the second connecting plate 251 and the housing body can be achieved.

[0114] In an optional embodiment, if Figures 1 - 3 As shown, the flap assembly 30 includes a first flap 31 and a second flap 32 that are transmission-connected. The linear drive mechanism 40 can drive the first flap 31, the second flap 32 and the air inlet plate 50 to open or close synchronously. The synchronous action of multiple structures can be achieved through only one linear drive mechanism 40. The structure is simple and easy to operate.

[0115] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here.
