Description

Technical Field

[0001] The present application relates to the field of kitchen appliances, and in particular to a range hood and a housing thereof. Background Art

[0002] A range hood is an electrical appliance installed above the kitchen stove. Its main function is to purify the kitchen environment. The range hood can quickly remove the waste from stove combustion and the oil smoke generated during cooking that is harmful to the human body and discharge it outdoors. At the same time, it condenses and collects the oil smoke, reduces pollution, purifies the air, and has a safety guarantee function of anti-toxicity and explosion-proof.

[0003] According to different designs and functions, range hoods can be divided into many types, the most common types include top suction type, side suction type and top side suction type. Taking the side suction type as an example, the side suction range hood is closer to the stove, which can effectively prevent the oil smoke from drifting directly to the kitchen staff, and at the same time improve the efficiency of oil smoke extraction.

[0004] In the existing side-suction range hood, a smoke collecting chamber is formed in the housing, and a smoke inlet is arranged on the guide plate on the housing. Under the action of the fan, the oil smoke is sucked into the smoke collecting chamber through the smoke inlet. In order to avoid the smoke inlet being visible and affecting the appearance, a condensation plate is usually added to the outside of the guide plate. A smoke inlet duct connected to the smoke inlet is formed between the guide plate and the condensation plate, and the oil smoke enters the smoke collecting chamber through the smoke inlet duct and the smoke inlet in turn.

[0005] After using the range hood for a long time, a lot of grease and dirt will accumulate on the condensing plate and the guide plate, affecting the range hood's oil fume extraction efficiency. In the related art, the condensing plate and the guide plate are fixed in a way that is difficult to disassemble, such as by fastening with screws, which makes it inconvenient for users to lift the condensing plate to clean and maintain the range hood.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0049] See also Figure 1 and Figure 2 The embodiment of the present application provides a range hood 1. The range hood 1 is an electrical appliance installed above a kitchen stove, and its main function is to purify the kitchen environment. It can quickly extract the waste burned by the stove and the oil smoke generated during cooking that is harmful to the human body, and filter or discharge it outdoors, thereby reducing pollution and purifying the air.

[0050] In some embodiments, the range hood 1 includes a housing 10 and a frame 20 disposed on the housing 10. The housing 10 is the main structure of the range hood 1 and supports the operation of the entire device, while the frame 20 is a supporting structure disposed on the housing 10 and is used to fix and support the housing 10 so that it can be stably installed on the upper part or side of the stove in the kitchen. An air outlet 20a is provided on the frame 20, and the air outlet 20a is connected to the smoke inlet 11a through the housing 10, so that the user discharges oil smoke to the outside.

[0051] Range hoods 1 can be divided into many types according to different designs and functions. Common types include top suction, side suction and top-side dual suction. Top suction range hoods are usually installed above the ceiling of the kitchen, and the oil smoke is sucked upwards through the suction force at the top, which is suitable for open kitchens. Side suction range hoods are closer to the stove, which can effectively prevent the oil smoke from drifting directly to the kitchen staff, and at the same time improve the efficiency of oil smoke extraction. Top-side dual suction range hoods combine the advantages of top suction and side suction, and absorb oil smoke from the sides and top at the same time, providing more comprehensive suction coverage.

[0052] Taking the side-suction range hood 1 as an example, a smoke collecting chamber 10a is formed in the housing 10. Specifically, the housing 10 may include a top shell 16, a bottom shell 17, a left shell (not shown), a right shell 18, a rear shell (not shown) and a flow guide 11, the top shell 16 and the bottom shell 17 are arranged relatively to each other along the up-down direction of the range hood 1 and are both connected to the left shell, the right shell 18, the rear shell and the flow guide 11, the left shell and the right shell 18 are arranged relatively to each other along the left-right direction of the range hood 1 and are both connected to the top shell 16, the bottom shell 17, the rear shell and the flow guide 11, the rear shell and the flow guide 11 are arranged relatively to each other along the front-back direction of the range hood 1 and are both connected to the top shell 16, the bottom shell 17, the left shell and the right shell 18, and the top shell 16, the bottom shell 17, the left shell, the right shell 18, the rear shell and the flow guide 11 jointly constitute the smoke collecting chamber 10a.

[0053] In addition, the guide 11 is also used to guide the flow of oil smoke and gas to ensure that the oil smoke can be effectively sucked into the smoke collecting chamber. The guide 11 is provided with a smoke inlet 11a connected to the smoke collecting chamber 10a. Under the suction effect of the fan in the frame 20, the indoor oil smoke is sucked into the smoke collecting chamber 10a from the smoke inlet 11a under the guiding effect of the guide 11, and is discharged outdoors through the internal air duct of the frame 20 (for example, the air duct formed by the volute of the fan) and the air outlet 20a.

[0054] On the one hand, in order to avoid the smoke inlet 11a being visible and affecting the appearance, on the other hand, in order to avoid the smoke inlet 11a being directly exposed and causing excessive suction force, the flame is pulled too far away from the gas stove and cooking utensils (such as a wok), resulting in reduced heating efficiency of the gas stove. The housing 10 may further include a condensing member 12 that is opposite to and spaced from the guide member 11, and a smoke inlet duct 10b that is connected to the smoke inlet 11a is formed between the condensing member 12 and the guide member 11, and the oil smoke enters the smoke collecting chamber 10a through the smoke inlet duct 10b and the smoke inlet in turn. In this process, the guide member 11 and the condensing member 12 can play a role in condensing oil smoke and water vapor, so that the oil or water droplets formed after condensation are attached to the guide member 11 and the condensing member 12, thereby reducing the condensation of water and oil on the inner wall of the smoke collecting chamber 10a, the fan blades and other components, and providing convenience for cleaning.

[0055] After using the range hood 1 for a long time, a large amount of grease and dirt will accumulate on the surfaces of the guide member 11 and the condensation member 12 that form the smoke inlet duct 10b. In addition, grease and dirt will also accumulate inside the smoke collecting chamber 10a, affecting the smoke extraction efficiency of the range hood 1. In the related art, the guide member 11 and the condensation member 12 are fixed in a difficult-to-disassemble manner, such as by screws, which makes it inconvenient for users to disassemble or lift the condensation member 12 to clean or maintain the guide member 11, the condensation member 12 and the smoke collecting chamber 10a.

[0056] To solve the above problems, please refer to Figure 2 and Figure 3 In some embodiments, the condensing member 12 is rotatably connected to the guide member 11. Based on the rotatable connection between the condensing member 12 and the guide member 11, the condensing member 12 has at least two states, one of which is a covered state, that is, Figure 1 As shown, when the range hood 1 is working normally, in the front-to-back direction of the range hood 1, the condensing member 12 is arranged in front of the air guide member 11, that is, on the side close to the stove, and the condensing member 12 is covered at the smoke inlet 11a and the air guide member 11 forms the aforementioned smoke inlet duct 10b. Under the action of the fan in the frame 20, the indoor oil smoke is sucked into the smoke inlet duct 10b and condensed in the condensing member 12 and the air guide member 11.

[0057] The other state is the open state, that is, Figure 2 As shown, when the box body 10 needs to be cleaned or maintained, the condensation member 12 rotates relative to the guide member 11 to expose the smoke inlet 11a. This makes it easy to clean the wall of the smoke inlet duct 10b formed by the guide member 11, the smoke inlet 11a and the condensation member 12, and also makes it easy for the user to reach into the smoke collecting chamber 10a to clean it.

[0058] The rotating connection design between the condensing member 12 and the guide member 11 allows the user to easily open and close the condensing member 12, so that the condensing member 12 can be switched between a closed state and an open state. This design not only simplifies the cleaning process, but also facilitates the cleaning and maintenance of the internal mechanism of the housing 10, thereby significantly improving the service life and overall performance of the range hood 1.

[0059] See also Figure 2-3 In some embodiments, the housing 10 further includes a support member 13. The support member 13 includes a rotating end 131 and a free end 132 that can be driven by an external force, the rotating end 131 is rotatably connected to one of the condensing member 12 and the flow guide member 11, and the free end 132 is detachably connected to the other of the condensing member 12 and the flow guide member 11, so as to support the condensing member 12 after the condensing member 12 rotates relative to the support member 13 (for example, the condensing member 12 is in the aforementioned open state after the rotation).

[0060] Since the support member 13 has a free end 132 and a rotating end 131, the user does not need to continuously support the condensation member 12 with his hands when flipping it open. After the condensation member 12 is flipped open, the user only needs to simply rotate the free end 132 of the support member 13 to fix it on the condensation member 12 or the guide member 11, so that the support member 13 is supported between the condensation member 12 and the guide member 11. This operation allows the condensation member 12, the guide member 11 and the support member 13 to form a stable triangular support structure, which not only ensures that the condensation member 12 remains stably opened during cleaning and maintenance, but also completely frees the user's hands, making the cleaning and maintenance process easier.

[0061] In one embodiment, the rotating end 131 of the support member 13 is rotatably connected to the condensation member 12, and the free end 132 is detachably connected to the guide member 11. In actual operation, the user flips open the condensation member 12 and rotates the free end 132 of the support member 13 in the direction toward the guide member 11, so that the free end 132 is connected to the guide member 11 to support the condensation member 12 in an open state.

[0062] In another embodiment, the rotating end 131 of the support member 13 is rotatably connected to the guide member 11, and the free end 132 is detachably connected to the condensation member 12. In actual operation, the user flips open the condensation member 12 and rotates the free end 132 of the support member 13 in the direction toward the condensation member 12, so that the free end 132 is connected to the condensation member 12 to support the condensation member 12 in an open state.

[0063] The free end 132 of the support member 13 is detachably connected to the condensation member 12 or the flow guide member 11. For example, the rotating end 131 of the support member 13 is hinged to the flow guide member 11. A card slot is provided on the condensation member 12, and the free end 132 can be inserted into the card slot. The user can manually rotate the free end 132 into or out of the card slot; or an abutment surface is formed on the condensation member 12, and the free end 132 can abut on the abutment surface to support the condensation member 12 in an open state. The detachable connection between the free end 132 and the condensation member 12 or the flow guide member 11 can be a detachable connection or abutment, which is not limited in this application.

[0064] The range hood 1 housing 10 of the embodiment of the present application demonstrates its simple and efficient design concept through the design of manually rotating the support member 13. Compared with the traditional complex mechanical or electronic control system driving the support member 13 to rotate, the design of manually rotating the support member 13 does not need to rely on additional complex components, thereby reducing the number of required parts. This simplified design reduces production and material costs.

[0065] Please continue reading Figure 2In one embodiment, a receiving space 12a is formed on one side of the condensing member 12 facing the air guide member 11, and the supporting member 13 can be received in the receiving space 12a, so that the space of the condensing member 12 can be effectively utilized and the supporting member 13 is prevented from occupying additional external space. Moreover, the supporting member 13 is hidden in the condensing member 12, providing a neat appearance and enhancing the overall aesthetics of the range hood 1.

[0066] Please continue reading Figure 2 Specifically, when the condensation piece 12 is in the open state, along the left and right directions of the range hood 1, the surface of the condensation piece 12 facing the air guide piece 11 is provided with two flange structures arranged at intervals, and the two flange structures and the condensation piece 12 define a accommodating space 12a, while the front side of the condensation piece 12 along the front-to-back direction of the box body 10 (that is, the lower side of the condensation piece 12 when the condensation piece 12 is in the covered state) is not provided with a flange structure. When the condensation piece 12 is in the covered state, it is ensured that the oil smoke can smoothly flow into the smoke inlet 11a from the lower side, thereby avoiding the problem of reduced efficiency of inhaling oil smoke, and the flange structure can also serve as a barrier to reduce the lateral escape of oil smoke before entering the smoke inlet 11a, thereby improving the efficiency of collecting oil smoke.

[0067] Please continue reading Figure 2 In some embodiments, the condensing member 12 is further provided with a first clip and part 123, which is arranged on a side of the condensing member 12 away from the rotation connection with the guide member 11, and the guide member 11 is provided with a second clip and part 113 adapted to the first clip and part 123. The first clip and part 123 and the second clip and part 113 are engaged and matched, ensuring the close fit of the condensing member 12 and the guide member 11 in the covered state. The engagement mechanism effectively prevents the condensing member 12 from being accidentally lifted up during use or when subjected to external force, thereby ensuring the safe operation of the range hood 1. When the user needs to lift (turn over) the condensing member 12 for cleaning or maintenance, the user can release the engagement state of the first clip and part 123 and the second clip and part 113 through simple operation, which is convenient for the user to operate.

[0068] In some embodiments, the first clip portion 123 may be a hemispherical protrusion, and the second clip portion 113 may be a hemispherical groove adapted to the hemispherical protrusion, so that the user can easily align the protrusion and clip it into the groove when closing the condensing plate 121. The design of the hemispherical protrusion and the hemispherical groove reduces sharp edges, thereby reducing the risk of scratching or damaging the user and other components.

[0069] In some embodiments, the guide member 11 includes a guide plate 111, and the condensation member 12 includes a condensation plate 121, wherein the rotating end 131 of the support member 13 is rotatably connected to the condensation plate 121, and the free end 132 is detachably connected to the guide plate 111; or, the rotating end 131 of the support member 13 is rotatably connected to the guide plate 111, and the free end 132 is detachably connected to the condensation plate 121. Exemplarily, the rotating end 131 of the support member 13 is hinged to the condensation plate 121, and a slot is provided on the guide plate 111, and the free end 132 of the support member 13 is rotated into the slot to support the condensation plate 121 in an open state. The structure of directly setting the support member 13 on the guide plate 111 or the condensation plate 121 is simple and convenient for users to use. Fewer parts and a simplified connection mechanism help reduce production costs, making the product more economical and affordable.

[0070] Please continue reading Figure 2-3 In some embodiments, the condensation member 12 of the present application may include a condensation plate 121 and a first connection structure 122 disposed on the condensation plate 121, and the guide member 11 may include a guide plate 111 and a second connection structure 112 disposed on the guide plate 111, the first connection structure 122 and the second connection structure 112 are rotatably connected, the first connection structure 122 can provide a stable support for the condensation plate 121, and the second connection structure 112 can provide a stable support for the guide plate 111, reduce the vibration or shaking caused by the unstable connection between the condensation plate 121 and the guide plate 111 during the rotation process, and enhance the stability of the connection between the condensation plate 121 and the guide plate 111. And by providing the first connection structure 122 and the second connection structure 112 that are rotatably connected to achieve the rotational connection between the condensation plate 121 and the guide plate 111, the friction and wear between the condensation plate 121 and the guide plate 111 can be reduced, thereby reducing the maintenance requirements of the condensation plate 121 and the guide plate 111, and extending the service life.

[0071] The rotating end 131 is rotatably connected to the condensing plate 121 or the first connecting structure 122, and the free end 132 is detachably connected to the guide plate 111 or the second connecting structure 112; or the rotating end 131 is rotatably connected to the guide plate 111 or the second connecting structure 112, and the free end 132 is detachably connected to the condensing plate 121 or the first connecting structure 122. That is, the support member 13 has a variety of supporting methods for the condensing member 12, and the manufacturer can choose the most suitable configuration according to the specific usage scenario, which can improve the flexibility of the specific design of the support member 13 without increasing the cost. More functions or improvements can also be added on this basis in the future.

[0072] like Figure 4 and Figure 5As shown, further, the support member 13, the first connection structure 122 and the second connection structure 112 form a modular support assembly, and the above structures are separated and modularized, which is easier to assemble, reducing the assembly time and complexity of the assembly process. The support member 13, the first connection structure 122 and the second connection structure 112 are allowed to be manufactured separately on the production line, and then assembled into a modular support assembly to meet the needs of mass production. By mass producing individual components, the manufacturing cost can be reduced.

[0073] Furthermore, in some embodiments, at least two groups of modular support components are arranged at intervals along the left and right directions of the box body 10. By setting multiple groups of modular support components to work together and provide more support points, a greater weight can be jointly borne, which is suitable for situations where a heavier condenser plate 121 needs to be supported. Exemplarily, the condenser 12 may include a glass cover plate. Since the glass cover plate is heavy, the support stability of the condenser 12 can be improved by setting a group of modular support components.

[0074] like Figure 4-5 As shown in the example, this embodiment is provided with two sets of modular support components, and the distance between the two sets of modular support components can be appropriately adjusted according to the length along the left and right directions of the box body 10 to adapt to condensation plates 121 of different sizes. The two sets of modular support components can provide a more balanced support force, increase the stability of the box body 10, and reduce shaking or vibration.

[0075] In one embodiment, if Figure 4 and Figure 7 As shown, the first connection structure 122 includes a first connection portion 1221 and a first bending portion 1222 bently connected to the first connection portion 1221, and the first connection portion 1221 is fixedly connected to the condensation plate 121; the second connection structure 112 includes a second connection portion 1121 and a second bending portion 1122 bently connected to the second connection portion 1121, the second connection portion 1121 is fixedly connected to the guide plate 111, and the second bending portion 1122 is rotatably connected to the first bending portion 1222 to achieve flipping between the condensation plate 121 and the guide plate 111; the first connection portion 1221 has a larger contact area with the condensation plate 121, which can improve the supporting stability of the support member 13 on the condensation plate 121 when the condensation plate 121 is in the open state, and can also provide a more uniform supporting force to reduce shaking in the supporting state. The second connection portion 1121 is also connected to the guide plate 111 to form a larger contact area. The second connection portion 1121 can provide a more stable support point for the support member 13, so that the support member 13 can support the condensation plate 121 more firmly.

[0076] In some embodiments, the angle between the first connection portion 1221 and the first bending portion 1222, the second connection portion 1121 and the second bending portion 1122 may be 90 degrees, that is, in an ideal state, the angle between the first connection portion 1221 and the first bending portion 1222, the second connection portion 1121 and the second bending portion 1122 may be 90 degrees. Affected by the process accuracy, etc., the angle between the first connection portion 1221 and the first bending portion 1222, the second connection portion 1121 and the second bending portion 1122 may be about 90 degrees, such as 89 degrees, 91 degrees, etc. The angle between the first connection portion 1221 and the first bending portion 1222, the second connection portion 1121 and the second bending portion 1122 may be achieved by a single bending process. The angles between the first connection portion 1221 and the first bending portion 1222, and between the second connection portion 1121 and the second bending portion 1122 can be set as needed. The present application does not limit the angles between the first connection portion 1221 and the first bending portion 1222, and between the second connection portion 1121 and the second bending portion 1122.

[0077] Specifically, the first connection portion 1221 and the first bending portion 1222 are an integrally formed structure, and the second connection portion 1121 and the second bending portion 1122 are an integrally formed structure, so that the production efficiency of the first connection structure 122 and the second connection structure 112 is higher, no assembly is required, and the connection points are reduced to improve the connection stability between the two.

[0078] In this embodiment, the rotating end 131 of the support member 13 is configured to be rotatably connected to the first connection structure 122, and the free end 132 of the support member 13 is configured to be detachably connected to the second connection structure 112; Figure 6-7 The rotating end 131 is rotatably connected to the first bending portion 1222; the free end 132 is detachably connected to the second bending portion 1122. Figure 2 or Figure 4 As shown, when the user lifts the condensation plate 121, the support member 13 rotatably connected to the first bending portion 1222 moves. Figure 3 or Figure 5 As shown, the free end 132 of the support member 13 is rotated to connect the free end 132 to the second bent portion 1122 to form a stable triangular support state.

[0079] It should be noted that the rotating end 131 of the support member 13 can also be configured to be rotatably connected to the second connecting structure 112, specifically, it can be rotatably connected to the second bending portion 1122, and the free end 132 is configured to be detachably connected to the first connecting structure 122, specifically, the shell is detachably connected to the first bending portion 1222, and the connection object and connection method of the rotating end 131 and the free end 132 can be set according to actual working conditions, which will not be repeated here.

[0080] As shown in Figures 6-7, the first connection portion 1221 of the modular support assembly is a first connection plate, which is fitted and arranged on the outer surface of the condensation plate 121 and connected by bolts, and the second connection portion 1121 is a second connection plate, which is fitted and arranged on the outer surface of the guide plate 111 and connected by bolts. The bolt connection provides a low-cost fastening method and has good mechanical strength, and can withstand repeated opening and closing operations in daily use. The first bending portion 1222 is a first bending plate, and the second bending portion 1122 is a second bending plate. The rotating end 131 of the support member 13 is rotatably connected to the first bending plate, and the free end 132 is detachably connected to the second bending plate. The first bending plate and the second bending plate can be partially stacked and connected, and the structure is more compact and can save space.

[0081] In other configurations, two groups of modular support components may share the same first connection portion 1221 and second connection portion 1121, both of which are in the form of long strips of plate-like structures, with both ends of the first connection portion 1221 along the length direction fixedly connected to the condensation plate 121, and both ends of the second connection portion 1121 along the length direction fixedly connected to the guide plate 111, and the long strip of plate-like structure provides a larger contact area, which helps to enhance the stability of the condensation plate 121 and the guide plate 111 in the supporting state. Alternatively, two groups of modular support components may share the same support member 13, and both of the support members 13 are in the form of long strips of plate-like structures, so that the long strip of plate-like structure provides a larger contact area, which helps to enhance the support stability of the support member 13 on the condensation member 12.

[0082] In order to improve the reliability of the connection, in one embodiment, Figure 6 and Figure 7 As shown, a limiting portion 132a is formed on the free end 132, and a matching portion 1123 is provided on the second bent portion 1122. The limiting portion 132a and the matching portion 1123 are mutually limited and can be separated from each other. Through the interaction between the limiting portion 132a and the matching portion 1123, the precise positioning between the free end 132 and the second bent portion 1122 is ensured to avoid the deviation of the connection position. This makes the connection between the free end 132 and the second bent portion 1122 more stable and prevents accidental separation.

[0083] Specifically, the limiting portion 132a is configured as a limiting bayonet, and the matching portion 1123 is configured as an axial screw. The axial screw is fixed on the second bending portion 1122, and the axial screw is engaged with the limiting bayonet. The axial screw is a screw with different diameters (i.e., with steps), which is mainly used as a fastener in the field of mechanical engineering. The design of this screw enables it to provide a certain axial fixing effect during installation. The use of the axial screw can reduce the loosening caused by vibration or external force, thereby ensuring the stability and reliability of the connection with the second bending portion 1122. Exemplarily, the axial screw in this embodiment has a first shaft portion and a second shaft portion formed in sequence, the outer diameter of the first shaft portion is greater than the outer diameter of the second shaft portion, and the second shaft portion is installed on the second bending portion 1122 to form an axial limit. The limiting bayonet is opened on the end of the free end 132, and the size of the limiting bayonet is adapted to the size of the second shaft portion. When in the supporting state, the limiting bayonet can be firmly clamped on the second shaft portion.

[0084] Furthermore, the limited slot on the free end 132 may cause stress concentration, especially at the edge of the limited slot. In order to solve this problem, the support member 13 is designed to point from the rotating end to the free end 132, and the width of the support member 13 gradually increases. The widened free end 132 of the support member 13 provides a larger cross-sectional area, which helps to distribute the load more evenly and improve the bearing capacity of the free end 132 of the support member 13, thereby enhancing the connection stability between the support member 13 and the second bent portion 1122.

[0085] like Figure 5 As shown, the opening angle of the condensing member 12 and the flow guide member 11 under the support of the support member 13 can be 90 degrees, but it is not limited thereto. Figure 8 As shown, in order to further realize that the condensation plate 121 is in a variety of different opening angles, the support member 13 can be configured as a telescopic member. By adjusting the length of the telescopic member, the opening angle of the condensation plate 121 is adjusted for convenient operation, thereby optimizing the user experience. When not in use, the telescopic member can be retracted to the shortest length to save storage space.

[0086] Specifically, the telescopic member includes a plurality of sleeves 133 and an elastic locking member 134. The plurality of sleeves 133 are sequentially sleeved and can slide against each other. The design of the plurality of sleeves 133 provides flexibility of adjustment, facilitates the adjustment of the telescopic length, and allows the user to adjust the length of the telescopic member according to specific needs to adjust the condensation plate 121 to different opening angles. The structure is relatively simple and the weight is relatively light. Furthermore, the interconnected ends of two adjacent sleeves 133 are provided with through holes; when the through holes on the interconnected ends of the two adjacent sleeves 133 are aligned with the elastic locking member 134, the elastic locking member 134 is inserted into the through hole to lock the two adjacent sleeves 133. The elastic locking member 134 can ensure that the telescopic member can maintain a stable length after being adjusted to an appropriate length, and prevent sliding or displacement during use. When the elastic locking member 134 is retracted, the position between the adjacent sleeves 133 can be adjusted, thereby adjusting the telescopic length.

[0087] In some embodiments, see Figure 6-7 The box body 10 of the present application also includes a first damping component 14 and a second damping component 15. The first damping component 14 connects the rotating end 131 and the first connecting structure 122 to achieve damped rotation between the rotating end 131 and the first connecting structure 122. The first damping component 14 can keep the support member 13 from rotating (unless subjected to force from the user), that is, the support member 13 will not accidentally swing or collide with other components due to gravity, thereby reducing the possibility of damaging other components or generating noise.

[0088] The second damping assembly 15 connects the first connection structure 122 and the second connection structure 112 to achieve damped rotation between the first connection structure 122 and the second connection structure 112. The second damping assembly 15 can provide a damping force for the flipping of the condensation plate 121, which can prevent the condensation plate 121 from accidentally closing when it is not stably supported by the support member 13, thereby reducing the risk of pinching or causing damage to the condensation plate 121. The first damping assembly 14 and the second damping assembly 15 can both reduce the wear that may be caused by rapid rotation, which helps to extend the service life of the modular support assembly.

[0089] Compared with the related technology that only relies on damping force to maintain the open state of the condensation plate 121, in actual use, since the condensation plate 121 can perform preliminary condensation and separation on the oil smoke, a certain amount of water vapor will be generated in this process, and the water vapor will condense into water droplets on the condensation plate 121. Therefore, it is necessary to paste a glass cover plate on the condensation plate 121 to prevent the surface of the condensation plate 121 from being damaged, and to facilitate subsequent cleaning and maintenance work. However, the overall weight of the condensation plate 121 is increased by pasting a glass cover plate on it. There is a certain risk in relying solely on damping force to maintain the open state of the condensation plate 121 and the glass cover plate. This embodiment can adapt to condensation plates 121 of different weights and the glass cover plates thereon. In addition to reducing the risk of arbitrary rotation of the condensation plate 121 and the glass cover plate through the second damping component 15, additional physical support is provided through the support member 13, thereby improving the support stability of the heavier condensation member 12.

[0090] In other configurations, the housing 10 may only include the first damping assembly 14, which is connected to the rotating end 131 and the first connecting structure 122 to achieve damped rotation between the rotating end 131 and the first connecting structure 122. Since the support member 13 does not frequently swing due to gravity, the maintenance requirements due to wear are reduced.

[0091] In another configuration, the housing 10 may only include the second damping assembly 15, which is connected to the first connection structure 122 and the second connection structure 112 to achieve damped rotation between the first connection structure 122 and the second connection structure 112. The second damping assembly 15 can slow down the turning speed of the condensation plate 121 to temporarily maintain the open state, giving the user more time to adjust and align the support member 13, thereby improving the safety of the operation.

[0092] See also Figure 8 In one embodiment, a first connection hole 1222a is provided on the first connection structure 122, and a second connection hole 131a is provided on the rotating end 131 at a position opposite to the first connection hole 1222a. The first damping assembly 14 includes a shaft portion 1411 and a damping member 142. The shaft portion 1411 is passed through the first connection hole 1222a and the second connection hole 131a, that is, the rotating end 131 is rotatably connected to the first connection structure 122 through the shaft portion 1411. The damping member 142 is sleeved on the shaft portion 1411 to provide a damping force for the relative rotation of the rotating end 131 and the first connection structure 122. The damping force can prevent the rotating end 131 from swinging freely without being rotated by an external force from the user, thereby reducing the wear of the first connection structure 122 caused by the rapid rotation of the rotating end 131, and making the rotation process smoother, reducing impact and noise.

[0093] Furthermore, the first damping assembly 14 includes a semi-hollow rivet 141, which includes a rotating shaft portion 1411 and two stop portions 1412, and the two stop portions 1412 are respectively arranged at both ends of the rotating shaft portion 1411. The semi-hollow rivet 141 is a mechanical part commonly used for fastening, and is characterized in that the upper and middle portions are solid structures, while the tail portion is a hollow structure. When the semi-hollow rivet 141 is installed, the hollow portion of the tail portion will be squeezed and turned outward to form a stop portion 1412, and the damping member 142, the rotating end 131 and the side wall of the hole corresponding to the second connecting hole 131a are limited between the two stop portions 1412. The stop portion 1412 can prevent the damping member 142, the rotating end 131 and the first connecting structure 122 from falling off or shifting, thereby ensuring safety during use.

[0094] In addition, this embodiment can also change the tightness between the damping member 142 and the component matched with the damping member 142 by adjusting the pressure applied to the semi-hollow rivet 141. By changing the deformation degree of the damping member 142 to provide a greater damping force, a greater riveting force will lead to a tighter fit between the damping member 142, the rotating end 131 and the first connecting structure 122, thereby increasing the damping force. A smaller riveting force will lead to a looser fit, reducing the damping force.

[0095] Of course, one or more damping members 142 may be provided, and one or more damping members 142 may be provided between the first connection structure 122 and the rotating end 131; or, one or more damping members 142 may be provided on the side of the first connection structure 122 away from the rotating end 131; or, one or more damping members 142 may be provided on the side of the rotating end 131 away from the first connection structure 122. The damping members 142 provided at different positions may adapt to different loads and usage conditions, thereby enhancing the adaptability of the structure. The damping members 142 may be provided in specific numbers as required, and may be provided at different positions, providing a variety of adjustment options to adapt to different usage scenarios and user needs.

[0096] In some embodiments, the damping member 142 includes at least two, specifically, one of the damping members 142 is configured as a graphite gasket, which is suitable for various high temperature, high pressure and corrosive environments. The other damping member 142 is configured as an explosion-proof gasket, which has certain elasticity and corrosion resistance, and can withstand certain temperature and pressure. Both the graphite gasket and the explosion-proof gasket can effectively absorb and reduce the noise and vibration generated during the rotation process, providing a quieter and more comfortable use environment.

[0097] In some embodiments, two stacked damping members 142 are provided, one is a graphite gasket and the other is an explosion-proof gasket. The semi-hollow rivet 141 is sequentially penetrated through the first bending portion 1222, the support member 13, the graphite gasket and the explosion-proof gasket, that is, the two damping members 142 are arranged on the side of the rotating end 131 away from the first bending portion 1222. The outer diameter of the explosion-proof gasket is larger than the outer diameter of the graphite gasket, and can be covered on the side of the graphite gasket away from the support member 13 to prevent external impurities from entering.

[0098] It should be noted that the structure of the second damping assembly 15 may be the same as or similar to the structure of the first damping assembly 14 , or may be different, which will not be described in detail herein.

[0099] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
