Description

Technical Field

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

[0002] In the prior art, a range hood includes a casing, a flap assembly, an air inlet plate, and a linear drive device, wherein the linear drive device can drive the flap assembly to switch between an open state and a closed state.

[0003] However, in existing range hood designs, when the flap assembly is closed, the force applied by the drive device to the flap assembly has an upward or downward component, preventing the flap assembly from closing tightly. This results in a large gap between the flap assembly and the outer casing. On one hand, this causes cooking fumes to escape from inside the fume treatment device, affecting the cleanliness of the kitchen environment and the user experience. On the other hand, the gap between the flap assembly and the outer casing also exposes the internal structure of the fume treatment device, compromising its appearance when closed. Thirdly, it can also damage the flap assembly.

[0004] Therefore, there is an urgent need to design a new fume treatment device to improve the problems of odor escaping from inside the device, the unsightly appearance of the device when it is closed, and the easy damage to the flap assembly. Utility Model Content

[0026] A transmission assembly is rotatably connected to the first flap and the sliding mechanism, and is fixedly connected to the second flap.

[0027] As an optional solution, the transmission assembly includes:

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

[0070] Example 1

[0071] like Figures 1-2As shown in the figure, this embodiment of the present disclosure provides an oil fume treatment device 100. The oil fume treatment device 100 includes a main unit box (not shown in the figure) and a smoke collection chamber assembly connected to each other. The main unit box is provided with a fan main unit box. The smoke collection chamber assembly has an air inlet 511. When the main unit box is working, the oil fumes outside the oil fume treatment device 100 can enter through the air inlet 511. The oil fumes pass through the smoke collection chamber assembly and the main unit box in sequence. The oil fumes are purified in the main unit box. The purified gas is discharged from the air outlet of the main unit box (not shown in the figure) to the external pipeline or indoors.

[0072] In the prior art, the smoke collection chamber assembly includes a housing 20, a flap assembly 30, and a linear drive mechanism 40. When the flap assembly 30 is in the closed state, the force applied by the linear drive mechanism 40 to the flap assembly 30 will have an upward or downward component, causing the flap assembly 30 to be unable to be in a tightly closed state. This results in a large gap between the flap assembly 30 and the housing 20. On the one hand, this causes the oil fume odor inside the fume treatment device 100 to overflow, affecting the cleanliness of the kitchen environment and the user experience. On the other hand, the gap between the flap assembly 30 and the housing 20 also exposes the internal structure of the fume treatment device 100, making it impossible to ensure a good appearance of the fume treatment device 100 when closed. Thirdly, it can also lead to damage to the flap assembly 30.

[0073] To solve the above problems, such as Figures 2-4 As shown, the linear drive mechanism 40 includes a drive body 41 and an output end 42. The output end 42 can move linearly relative to the drive body 41. The drive body 41 is connected to the housing 20 in a transmission connection, and the output end 42 is connected to the flap assembly 30 in a transmission connection. When the flap assembly 30 is in the closed state, the extension direction of the output end 42 is perpendicular to the flap assembly 30.

[0074] like Figure 3 As shown, when the flap assembly 30 is in the closed state, the extension direction of the linear drive mechanism 40 is perpendicular to the flap assembly 30. When the flap assembly 30 is in the closed state, it is only subjected to the backward pulling force of the linear drive mechanism 40. This avoids the flap assembly 30 receiving upward or downward force components, ensuring the accuracy of the flap assembly 30's position when it is in the closed state. It also prevents the flap assembly 30 from being misaligned due to upward or downward external forces, thus avoiding damage to the flap assembly 30. Furthermore, it prevents the leakage of oil fume odor from the inside of the fume treatment device 100 due to a large gap between the flap assembly 30 and the outer casing 20, and also prevents the exposure of the internal structure of the fume treatment device 100 due to a large gap between the flap assembly 30 and the outer casing 20, ensuring a good appearance of the fume treatment device 100 when it is in the closed state.

[0075] In an alternative embodiment, such as Figures 2-6 As shown, the flap assembly 30 includes a first flap 31, which includes a first flap body 311 and a first mounting base 313 disposed thereon. The first flap body 311 is rotatable relative to the housing 20. The first mounting base 313 is rotatably connected to the output end 42 through a first rotatable connection position M1. The housing 20 includes a housing body and a second mounting base 25 disposed thereon. The drive body 41 is rotatably connected to the second mounting base 25 through a second rotatable connection position M2. When the flap assembly 30 is in the closed state, the line M1M2 connecting the first rotatable connection position M1 and the second rotatable 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 extension direction of the linear drive mechanism 40 is perpendicular to the flap assembly 30.

[0076] In an alternative embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the first mounting base 313 includes a first connecting plate 3131 and a first mounting plate 3132. The first connecting plate 3131 is connected to the flip plate assembly 30, and the first mounting plate 3132 is connected to the first connecting plate 3131. The output end 42 is rotatably connected to the first mounting plate 3132. By abutting the surfaces of the first connecting plate 3131 and the flip plate assembly 30, a stable connection between the first connecting plate 3131 and the flip plate assembly 30 can be achieved.

[0077] For example, the first connecting plate 3131 and the flip plate assembly 30 can be fixedly connected by a first fixing structure in various ways such as pins, screws, snap-fit ​​assemblies, and magnetic assemblies. All structures that can achieve a stable connection between the first connecting plate 3131 and the flip plate assembly 30 are within the protection scope of the embodiments disclosed herein.

[0078] For example, the number of first fixing structures can be one, two, three, or more. When there is only one first fixing structure, the installation process of the first mounting base 313 and the flip plate 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 flip plate assembly 30 can be achieved.

[0079] In an alternative embodiment, such as Figure 5 As shown, there are two first mounting plates 3132, which are arranged at intervals along the width direction of the fume treatment device 100. The output end 42 is located between the two first mounting plates 3132. The output end 42 is rotatably connected to the first mounting plate 3132 through the first rotating shaft. The arrangement of the two mounting plates 3132 can achieve stable support for the first rotating shaft and ensure a good rotatable connection between the output end 42 and the first mounting base 313.

[0080] In an alternative embodiment, such as Figure 6 As shown, the second mounting base 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 drive body 41 is rotatably connected to the second mounting plate 252. By abutting the surface of the second connecting plate 251 against the outer shell body, a stable connection between the second connecting plate 251 and the outer shell body can be achieved.

[0081] For example, the second connecting plate 251 and the outer shell body can be fixedly connected by a second fixing structure in various ways such as pins, screws, snap-fit ​​components, and magnetic components. All structures that can achieve a stable connection between the second connecting plate 251 and the outer shell body are within the protection scope of the embodiments disclosed herein.

[0082] For example, the number of second fixing structures can be one, two, three, or more. When there is only one second fixing structure, the installation process between the second mounting base 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.

[0083] In an alternative embodiment, such as Figures 1-3 As shown, the fume treatment device also includes an air inlet plate 50 with an air inlet 511. The air inlet plate 50 is connected to the outer shell 20 and the flap assembly 30 respectively. The flap assembly 30 includes a first flap 31 and a second flap 32 connected by transmission. 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 by only one linear drive mechanism 40. The structure is simple and easy to operate.

[0084] Specifically, such as Figures 1-3As shown, the fume treatment device 100 also includes a guide assembly 10 and a transmission assembly 60. The outer shell is rotatably connected to the first flap 31. The guide 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 drive mechanism 40 is rotatably connected to the outer shell, and the other end of the linear drive mechanism 40 is rotatably connected to the first flap 31. One end of the air inlet plate 50 is rotatably connected to the outer shell, 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 drive mechanism 40 is working, it can drive the first flap 31 to rotate relative to the outer shell. The rotation of the first flap 31 can cause the sliding mechanism 12 to slide relative to the fixed 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 rotate around the outer shell, and the air inlet plate 50 rotates and slides relative to the first flap 31. At the same time, the sliding of the sliding mechanism 12 relative to the fixed mechanism 11 can cause the various parts of the transmission assembly 60 to move relative to each other and change their relative positions. The transmission assembly 60 can realize the rotation of the second flap 32 relative to the first flap 31. In summary, the rotation of the first flap 31 driven by the linear drive mechanism 40 can simultaneously trigger the rotation of the air inlet 50 relative to the outer shell and the first flap 31, as well as the rotation of the second flap 32 relative to the first flap 31. In other words, the rotation of the linear drive mechanism 40 can achieve the linkage of the rotation of the first flap 31 relative to the outer shell, the rotation of the air inlet 50 relative to the outer shell and the first flap 31, and the rotation of the second flap 32 relative to the first flap.

[0085] The fume treatment device 100 of this disclosure embodiment can achieve the synchronous opening or closing of the first flap 31, the second flap 32 and the air inlet plate 50 by setting only one linear drive mechanism 40 and cooperating with the guide component 10 and the transmission component 60. Compared with the fume treatment device 100 in the prior art, the fume treatment device 100 of this disclosure embodiment has the advantages of simple structure, easy assembly, small size, less prone to jamming and better fume extraction effect.

[0086] Specifically, when the fume treatment device 100 needs to be in the open state, the fume treatment device 100 from Figure 3 Switching to Figure 2In the current state, the push rod of the linear drive mechanism 40 extends, pushing the first flap 31, thereby causing the first flap 31 to rotate clockwise outward relative to the outer casing. The outward rotation of the first flap 31 causes the air inlet plate 50 to rotate counterclockwise outward relative to the outer casing. The rotation of the air inlet plate 50 causes the sliding mechanism 12 to slide downward relative to the fixed mechanism 11. The sliding of the sliding mechanism 12 causes the transmission component 60 to deform and rotate relative to the first flap 31. The transmission component 60 causes the second flap 32 to rotate clockwise relative to the first flap 31 and open. The first flap 31, the second flap 32, and the air inlet plate 50 can be opened synchronously and quickly using only the linear drive mechanism 40. Similarly, when the fume treatment device 100 needs to be in the closed state, the fume treatment device 100... Figure 2 Switching to Figure 3 In this state, the related structures move in the opposite way to the aforementioned movements.

[0087] In an alternative embodiment, such as Figures 2-8 As shown, the sliding mechanism 12 includes a first sliding member 121 and a second sliding member 122 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, wherein 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 quick 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.

[0088] In addition, such as Figure 8 As shown, the first sliding member 121 and the second sliding member 122 can be spliced ​​together to form a corresponding irregularly shaped sliding mechanism 12 according to the overall structural configuration of the fume treatment device 100, further improving the flexibility of the sliding mechanism 12 in connecting with 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 using existing standard parts to form an irregularly shaped sliding mechanism 12 suitable for the fume treatment device 100 of this disclosure embodiment, which can improve the production efficiency of the sliding mechanism 12 and effectively reduce the need for a separate injection molding production line for producing the irregularly shaped sliding mechanism 12, effectively reducing the production cost of the sliding mechanism 12, thereby effectively reducing the production cost of the fume treatment device 100.

[0089] In an alternative embodiment, such as Figure 8As shown, the first sliding member 121 and the second sliding member 122 have a concave-convex fit, which can effectively improve the installation efficiency and accuracy of the first sliding member 121 and the second sliding member 122, and enable the rapid assembly of the sliding mechanism 12. In addition, the concave-convex fit between the first sliding member 121 and the second sliding member 122 can prevent the separation of the first sliding member 121 and the second sliding member 122 under long-term stress, thus ensuring the long-term stability of the sliding mechanism 12.

[0090] In an alternative embodiment, such as Figure 8 As shown, the first sliding member 121 includes a sliding member body 1211 and two limiting parts 1213, which are disposed on both sides of the sliding member 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, and the rotating connecting members 1222 are rotatably connected to the transmission assembly 60 at the connection position P. The two rotating connecting members 1222 are disposed on both sides of the fixing member 1221; wherein, the sliding member body 1211 is fitted and fixedly connected to the fixing member 1221, and each limiting part 1213 is fitted and fixedly connected to the corresponding rotating connecting member 1222. Through surface fitting and fixed connection at multiple positions, a stable connection between the first sliding member 121 and the second sliding member 122 in various directions is achieved.

[0091] For example, the first slider 121 and the second slider 122 can be fixedly connected by fasteners such as screws, pins, magnetic structures, and snap-fit ​​assemblies. On the one hand, this achieves a stable connection between the first slider 121 and the second slider 122, preventing them from loosening or separating; on the other hand, it also enables quick assembly and disassembly of the first slider 121 and the second slider 122.

[0092] In an alternative embodiment, such as Figure 8 As shown, the slider body 1211 is provided with a recess 1212, and the fixing member 1221 includes a fixing member body 12211 and a protrusion 12212 provided thereon. Since the overall area of ​​the slider body 1211 and the fixing member 1221 is large, the recess 1212 and the protrusion 12212 with a large volume can be provided. The large recess 1212 and the protrusion 12212 can achieve a better limiting effect between the first slider 121 and the second slider 122.

[0093] Furthermore, since the bottom surface of the recessed portion 1212 is as follows Figure 2The end face of the fixing mechanism 11 shown mates with the guide to achieve the desired effect. Therefore, once 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 sliding body 1211, the bottom surface of the sliding body 1211 will be in contact with the guide surface. Figure 8 The bottom surface of the recessed portion 1212 is flush with the bottom surface, which results in a smaller height for the limiting portion 1213. Consequently, the effective contact dimension between the limiting portion 1213 and its corresponding rotating connector 1222 along the height direction is smaller, making it difficult to effectively fix the limiting portion 1213 and the rotating connector 1222 using fasteners. However, by providing the recessed portion 1212, the bottom surface of the recessed portion 1212 is flush with the bottom surface of the rotating connector 1222. Figure 2 Under the premise that the end face of the fixing mechanism 11 shown is in effective contact, it can ensure that the limiting part 1213 and its corresponding rotating connector 1222 have a large contact size in the height direction, and can achieve a large fastener to always firmly connect the limiting part 1213 and the corresponding rotating connector 1222.

[0094] like Figure 9 As shown, the rotating connector 1222 and the transmission assembly 60 are rotatably connected at the connection position P. Along the width direction of the fume treatment device 100, the rotating connector 1222 and the transmission assembly 60 are both located outside the first sliding member 121. The rotating connector 1222, the first sliding member 121, and the transmission assembly 60 together form the receiving space 70. The connection position P is located in the receiving space 70, and part of the air inlet plate 50 can move in the receiving space 70. Through the above arrangement, the rotating connector 1222, the first sliding member 121, the transmission assembly 60, and the air inlet plate 50 can be compactly arranged, reasonably reducing the space occupied by the above structure as a whole. This achieves a reasonable arrangement of the rotating connector 1222, the first sliding member 121, the transmission assembly 60, and the air inlet plate 50 in a limited space, and also avoids interference between the above parts during movement and avoids jamming problems during movement.

[0095] In an optional embodiment, the guide components 10 can be configured as two sets, with the two sets of guide components 10 arranged at intervals along the width direction of the fume treatment device 100. By coordinating the two sets of guide components 10, the rotation of the air inlet plate 50 relative to the first flap 31 can be synchronized at various positions along the width direction of the air inlet plate 50, preventing interference or jamming between the air inlet plate 50 and the first flap 31. Furthermore, the rotation of the second flap 32 relative to the first flap 31 can also be synchronized at various positions along the width direction of the second flap 32, preventing interference or jamming between the second flap 32 and the first flap 31.

[0096] Of course, in other alternative embodiments, the guide components 10 can be set to one, three, four or more groups, and the number of guide components 10 can be adjusted according to the specific size of the first flap 31.

[0097] like Figure 8 As shown, two rotating connectors 1222 are provided, located on both sides of the fixed member 1221 along the width direction of the fume treatment device 100. When the transmission assembly 60 is located on the left side of the air inlet plate 50, the transmission assembly 60 is rotatably connected to the rotating connector 1222 located on the left side; when the transmission assembly 60 is located on the right side of the air inlet plate 50, the transmission assembly 60 is rotatably connected to the rotating connector 1222 located on the right side. In other words, by manufacturing a uniform type of second sliding member 122, the second sliding member 122 can be set and installed in different positions, which can effectively reduce the processing cost of the second sliding member 122 and reduce the types of overall parts of the fume treatment device 100.

[0098] In an alternative embodiment, such as Figure 7 As shown, the rotating connector 1222 includes a connecting arm 12221 and a connecting block 12222. One end of the connecting arm 12221 is fixedly connected to the fixing member 1221, and the other end of the connecting arm 12221 is fixedly connected to the connecting block 12222. The transmission assembly 60 is rotatably connected to the connecting block 12222. The connecting block 12222 has high structural strength and hardness, so the connecting block 12222 can achieve a stable support effect relative to the transmission assembly 60.

[0099] In an alternative embodiment, such as Figure 7 As shown, the connecting block 12222 has a insertion slot 122221. The transmission component 60 is inserted into the insertion slot 122221 and is rotatably connected to the connecting block 12222 via a rotating shaft, thereby achieving a relatively stable connection between the connecting block 12222 and the transmission component 60. For example, rotating shafts are provided on both sides of the transmission component 60, and each rotating shaft is rotatably connected to the groove wall of the corresponding insertion slot 122221. The two rotating shafts are supported by the connecting block 12222, thereby achieving a stable support effect of the connecting block 12222 for the transmission component 60.

[0100] For example, such as Figure 7 As shown, the structure of the second sliding member 122 is relatively complex. The second sliding member 122 can be integrally formed by injection molding, extrusion molding, casting molding and other methods to improve the processing and forming efficiency of the second sliding member 122.

[0101] In an alternative embodiment, such as Figure 2 , Figure 3 as well as Figure 10As shown, the outer casing includes a front panel 21, a back panel 22, and a side baffle 24. The front panel 21 and the back panel 22 are arranged at intervals along the front-to-back direction. The side baffle 24 is disposed between the front panel 21 and the back panel 22. The front panel 21 has a smoke inlet 211, which is connected to the air inlet 511. The front panel 21, the side baffle 24, and the back panel 22 together form a first silencing cavity 23. The first silencing cavity 23 can initially isolate and absorb the noise generated by the main unit, reduce the noise received by the user from the main unit, and further improve the user's experience of using the fume treatment device 100.

[0102] In an alternative embodiment, such as Figures 1-3 As shown, the fume treatment device 100 also includes an oil filter 90, which is covered by the smoke inlet 211. The oil filter 90 can further improve the filtration effect on the fumes.

[0103] In an alternative embodiment, such as Figure 2 and Figure 10 As 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 along 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 constitute the second silencing cavity 80. The second silencing cavity 80 further enhances the isolation effect of noise generated by the main unit, further reduces the noise received by the user from the main unit, and further improves the user's experience of using the fume treatment device 100. Through the cooperation of the first silencing cavity 23 and the second silencing cavity 80, the noise received by the user from the main unit can be effectively reduced, and the user's experience of using the fume treatment device 100 can be effectively improved.

[0104] In an alternative embodiment, such as Figure 2 and Figure 10 As shown, the first side plate 312 can prevent oil fumes from overflowing from both sides of the first flap 31, thereby further improving the oil fume extraction effect of the oil fume treatment device 100.

[0105] In an optional embodiment, the air inlet 511 is elongated and extends along the width of the fume treatment device 100. The elongated air inlet 511 can further prevent the noise generated by the main unit from being transmitted outward, further reduce the noise received by the user from the main unit, and further improve the user's experience of using the fume treatment device 100.

[0106] like 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 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 installed to seal the gap between the air inlet plate 50 and the first side plate body 3121. On the one hand, it can avoid the formation of a gap that could cause injury to the user's fingers. On the other hand, the sealing plate 3122 can also prevent the fume from contaminating the transmission assembly 60, ensuring that the transmission assembly 60 always has a good cleanliness.

[0107] like Figure 2 , Figure 3 and Figure 9 As 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 disposed on the air inlet plate body 511. Along the width direction of the 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 portion of the fumes entering from the air inlet 511 from impacting the transmission assembly 60, which can further prevent the fumes from contaminating the transmission assembly 60 and ensure that the transmission assembly 60 always has a good cleanliness.

[0108] In an alternative embodiment, such as Figure 2 , Figure 3 and Figure 10 As 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, and the second connecting rod 62 is rotatably connected to both 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 easy to assemble. Figure 2 As 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 support effect for the second flap 32.

[0109] In an alternative embodiment, such as Figures 11-14As shown, the first flap 31 includes a first panel 3111, a first liner 3112, and a reinforcing member 3113. The first liner 3112 is disposed on the back side of the first panel 3111 and fixedly connected to the first panel 3111. The reinforcing member 3113 is clamped by the first panel 3111 and the first liner 3112. The fixing mechanism 11 is fixedly connected to the first liner 3112 and the reinforcing member 3113. The reinforcing member 3113 effectively enhances the strength and hardness of the first flap 31, enabling a stable connection between the first flap 31 and the fixing mechanism 11, preventing deformation of the first flap 31 during long-term use, and ensuring smooth movement of all parts of the fume treatment device 100. For example, the reinforcing member 3113 can be a structure with high strength and hardness, such as a stainless steel plate, copper plate, or aluminum plate.

[0110] Specifically, the first panel 3111 and the first liner 3112 can be stably connected by means of adhesive, fixed connection or other methods.

[0111] In an alternative embodiment, such as Figures 11-14 As shown, the first liner 3112 has a first receiving groove 31121, with the opening of the first receiving groove 31121 facing the first panel 3111. A reinforcing member 3113 is disposed within the first receiving groove 31121. The reinforcing member 3113 is only disposed at the location where the guide assembly 10 is installed on the first flip plate 31. This ensures stable installation of the guide assembly 10 while preventing the first flip plate 31 from becoming too heavy, thus guaranteeing a good flipping effect. Furthermore, the first receiving groove 31121 effectively improves the installation efficiency and accuracy of the reinforcing member 3113 and the first liner 3112. Additionally, since the first receiving groove 31121 protrudes from the back of the first liner 3112, it facilitates quick identification and positioning by operators, further improving the installation efficiency and accuracy of the guide assembly 10 and the first flip plate 31.

[0112] In an alternative embodiment, such as Figures 11-14 As shown, the first flap 31 also includes a first mounting base 313, which includes a first connecting plate 3131 and a first mounting plate 3132. The first liner 3112 has a mounting opening 31122. The first connecting plate 3131 is clamped between the first panel 3111 and the first liner 3112. The first mounting plate 3132 extends through the mounting opening 31122 to the side of the first liner 3112 away from the first panel 3111. The first connecting plate 3131 is clamped between the first panel 3111 and the first liner 3112, which can achieve a stable connection between the first connecting plate 3131 and the first panel 3111 and the first liner 3112 respectively, and prevent the first mounting base 313 from falling off the first liner 3112.

[0113] In an alternative embodiment, such as Figures 11-14 As shown, a second receiving groove 31123 is provided on the first liner 3112. The opening of the second receiving groove 31123 is set facing the first panel 3111. The mounting port 31122 is opened on the bottom surface of the second receiving groove 31123. The first connecting plate 3131 is accommodated in the second receiving groove 31123. By setting the second receiving groove 31123, the installation efficiency and installation accuracy of the first mounting base 313 and the first liner 3112 can be effectively improved.

[0114] In an alternative embodiment, such as Figures 11-14 As shown, the first liner 3112 includes a first limiting structure, and the first connecting plate 3131 is provided with a second limiting structure. The first and second limiting structures cooperate to achieve rapid positioning of the first connecting plate 3131 and the first liner 3112, improving the assembly efficiency and accuracy of the first liner 3112 and the first connecting plate 3131. For example, as... Figures 11-14 As shown, the first limiting structure can be a limiting hole 31124 formed on the bottom surface of the second receiving groove 31123, and the second limiting structure can be a limiting member 3133 disposed on the first connecting plate 3131. The first and second limiting structures achieve a concave-convex fit through the insertion and engagement of the limiting hole 31124 and the limiting member 3133. Of course, in other embodiments, the first limiting structure can be a limiting member, and the second limiting structure can be a limiting hole, achieving the same effect.
