Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood with a concealed oil cup. Background Technology

[0002] With current technology, range hoods have entered the kitchens of thousands of households. Range hoods can remove the oil fumes produced in the kitchen during the cooking process, reduce the coughing problem caused by oil fumes when people are cooking, and keep the kitchen clean and hygienic.

[0003] The oil cup, as an important component of a range hood, serves to collect oil. Traditional range hoods typically have their oil cups installed at the bottom of the hood casing. When the hood is not in use, the oil cup is usually visible, which is aesthetically unappealing. Furthermore, the exposed oil cup is prone to accumulating dust and grease, making it difficult to clean.

[0004] Therefore, there is an urgent need to provide a range hood with a concealed oil cup to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a range hood with a concealed oil cup. When not in use, the oil cup is concealed, which improves the overall aesthetics, helps to ensure the cleanliness of the appearance, and makes cleaning convenient and quick.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A range hood with a concealed oil cup includes a housing, a flap, and an oil cup. The oil cup is detachably connected to the bottom of the housing. The housing contains a smoke collection chamber. The flap is movably connected to the smoke collection chamber, and the two can be opened or closed relative to the housing via a drive mechanism. When opened, the smoke collection chamber moves out of the housing, and the flap flips relative to the smoke collection chamber. When fully closed, the flap fits against and covers the front side of the housing and can block the front side of the oil cup.

[0008] As an alternative, the housing includes outer side plates located on the left and right sides, the bottom of which is lower than the oil cup to cover the left and right sides of the oil cup.

[0009] As an alternative, the housing also includes a bottom plate located at the bottom, between the two outer plates, with the oil cup detachably connected to the bottom of the bottom plate, and the bottom plate having multiple oil leakage holes.

[0010] As an alternative, there is a gap between the base plate and the outer side plate.

[0011] As an alternative, the oil cup is installed at the bottom of the housing by pulling it out from the front and back.

[0012] As an optional solution, the bottom ends of the base plate are equipped with hanging ears, and the hanging ears are provided with sliding grooves extending in the front-to-back direction. The oil cup is a box with an open top. The upper ends of the left and right side plates of the box are bent horizontally to form mounting parts, and the mounting parts are installed in the sliding grooves.

[0013] As an optional solution, a limiting part is provided on the front side of the mounting part, the limiting part is set at an angle to the mounting part, and the limiting part can abut against the hanging ear.

[0014] As an alternative, the oil cup includes a bottom side plate that is horizontally positioned at the bottom, an inclined plate that is connected to the front end of the bottom side plate, the inclined plate that is inclined upward and forward, and a vertically positioned front side plate that is connected to the front end of the inclined plate.

[0015] As an optional solution, an oil viewing window is provided on the front side panel.

[0016] As an optional solution, the vertical projection of the bottom edge of the smoke collection chamber is located within the range of the oil cup.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a range hood with a concealed oil filter. In the working state, the flap and the smoke collection chamber are open relative to the housing, the smoke collection chamber moves out of the housing, and the flap flips relative to the smoke collection chamber to form a larger smoke collection area, effectively improving smoke collection efficiency, helping to prevent oil fumes from escaping, and improving kitchen cleanliness and air quality. In the non-working state, the flap and the smoke collection chamber are closed relative to the housing, so that the smoke collection chamber is hidden inside the housing, and the flap fits and covers the front side of the housing, making the range hood more compact and small when not in use, and the thickness of the housing can be made thinner, thus achieving a thinner body size and reducing the space occupied.

[0019] The removable oil cup facilitates the collection and cleaning of oil droplets. When fully closed, the flap conceals the front of the oil cup, making it hidden when not in use. This enhances the aesthetics and keeps the appearance clean, reducing contact between the oil cup and dust, thus minimizing oil buildup and making cleaning easier. To clean the oil cup, simply open the flap to expose it, then remove the cup from the bottom of the casing – quick and easy cleaning. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] like Figure 1 As shown, this embodiment provides a range hood with a concealed oil cup, including a main housing (not shown) and a smoke collection mechanism. A fan mechanism is installed inside the main housing, and an opening is provided at the bottom of the main housing. The smoke collection mechanism is connected to the bottom of the main housing and located at the opening, allowing the smoke collection mechanism to communicate with the fan mechanism through the opening. When the range hood is needed to perform smoke extraction, the fan mechanism is activated, and the smoke collection mechanism extracts the generated fumes, preventing fumes from escaping. A decorative cover 8 can be optionally installed on the outside of the main housing for aesthetic purposes.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, the smoke collection mechanism includes a housing 1, a flap 3, and an oil cup 4. The oil cup 4 is detachably connected to the bottom of the housing 1. The housing 1 contains a smoke collection chamber 2. The flap 3 is movably connected to the smoke collection chamber 2. The two can be opened or closed relative to the housing 1 by a drive mechanism. When opened, the smoke collection chamber 2 moves out of the housing 1, and the flap 3 flips relative to the smoke collection chamber 2. When fully closed, the flap 3 fits and covers the front side of the housing 1 and can block the front side of the oil cup 4.

[0046] like Figure 1 As shown, in the working state, the flap 3 and the smoke collection chamber 2 are open relative to the housing 1, and the smoke collection chamber 2 moves out of the housing 1, achieving the same smoke extraction effect as a side-suction range hood. The flap 3 flips relative to the smoke collection chamber 2 to form a larger smoke collection area, effectively improving smoke collection efficiency, helping to prevent oil fumes from escaping, and improving the cleanliness and air quality of the kitchen; Figure 2 As shown, in the non-working state, the flap 3 and the smoke collection chamber 2 are closed relative to the housing 1, so that the smoke collection chamber 2 is hidden inside the housing 1, and the flap 3 fits and covers the front side of the housing 1, making the range hood more compact and small when not in use. The thickness of the housing 1 can be made thinner, thereby achieving a thinner body size and reducing the space occupied.

[0047] The detachable oil cup 4 facilitates the collection and cleaning of oil droplets. When fully closed, the flap 3 conceals the front of the oil cup 4, making it hidden when not in use. This enhances the aesthetics and keeps the appearance clean, reducing contact between the oil cup 4 and dust, thus minimizing oil buildup and making cleaning easier. To clean the oil cup 4, simply open the flap 3 to expose it, then remove the oil cup 4 from the bottom of the housing 1. Cleaning is quick and easy.

[0048] In this embodiment, as Figure 3 and Figure 10 As shown, the shell 1 includes a top plate 14 on the upper side, a bottom plate 13 on the lower side, a rear plate 15 on the rear side, and outer plates 11 on the left and right sides. The top plate 14 and the bottom plate 13 are arranged vertically at intervals. The bottom plate 13 is located between the two outer plates 11. The two outer plates 11 are respectively connected to the left and right sides of the top plate 14 and the bottom plate 13. The rear plate 15 is connected to the rear side of the top plate 14, the bottom plate 13 and the outer plates 11, thereby forming a shell 1 with a structure similar to a cuboid.

[0049] like Figure 1 As shown, the bottom of the outer panel 11 is lower than the oil cup 4 to cover the left and right sides of the oil cup 4, so that the oil cup 4 is also hidden on the left and right sides, which is conducive to the cleanliness of the range hood and further enhances its aesthetics.

[0050] like Figure 3 As shown, the oil cup 4 is detachably connected to the bottom of the base plate 13. The base plate 13 has multiple oil leakage holes 131, which facilitate oil droplets to flow into the oil cup 4 through the oil leakage holes 131.

[0051] Specifically, there is a gap between the base plate 13 and the outer plate 11. By maintaining a small gap between the base plate 13 and the outer plate 11, direct contact between the base plate 13 and the outer plate 11 can be avoided, which would cause oil to accumulate on the outer plate 11.

[0052] Furthermore, the oil cup 4 is installed at the bottom of the housing 1 by pulling it out from the front and back. This allows the oil cup 4 to be easily disassembled for cleaning.

[0053] Specifically, such as Figures 3 to 5 As shown, the bottom of the base plate 13 has hanging ears 16 at both ends. Each hanging ear 16 has a sliding groove 161 extending in the front-to-back direction. The oil cup 4 is a box with an open top. The upper ends of the left and right side plates 45 of the box are bent horizontally to form mounting parts 47, which are installed within the sliding grooves 161. To disassemble the oil cup 4, the user simply pulls it forward. To install, the user inserts the mounting part 47 into the sliding groove 161 and then pushes the oil cup 4 backward. The disassembly and assembly are quick and easy.

[0054] like Figure 4 As shown, the oil cup 4 includes a rear side plate 46, a left side plate 44, a right side plate 45, and a bottom side plate 41 located horizontally at the bottom. The left side plate 44 and the right side plate 45 are respectively located on the left and right sides of the bottom side plate 41. The rear side plate 46 is connected to the rear end of the bottom side plate 41. An inclined plate 42 is connected to the front end of the bottom side plate 41. The inclined plate 42 is inclined upward and forward, and a vertically arranged front side plate 43 is connected to the front end of the inclined plate 42. By setting the inclined plate 42, it is beneficial for oil droplets to flow backward, reducing the risk of oil dripping onto the bottom of the oil cup 4, effectively reducing oil stains on the surface of the oil cup 4, and improving the user experience.

[0055] Furthermore, such as Figure 4 and Figure 5 As shown, a limiting part 48 is provided on the front side of the mounting part 47. The limiting part 48 is set at an angle to the mounting part 47 and can abut against the hanging ear 16. When the oil cup 4 is installed on the hanging ear 16, after installation, the limiting part 48 stops on the outside of the slide groove 161 and abuts against the side of the hanging ear 16, ensuring the front and rear installation positions of the oil cup 4.

[0056] like Figure 4 As shown, an oil viewing window 431 is provided on the front panel 43. Through the oil viewing window 431, the oil level in the oil cup 4 can be observed, preventing oil spills and allowing for timely cleaning.

[0057] Furthermore, whether the smoke collection chamber 2 is open or closed, the vertical projection of the bottom edge of the smoke collection chamber 2 is always within the range of the oil cup 4, so that all the oil droplets on the front side of the smoke collection chamber 2 can enter the oil cup 4.

[0058] In addition, the orthographic projection of the rear plate 15 of the housing 1 in the vertical direction is always within the range of the oil cup 4, so that all the oil droplets on the rear plate 15 can enter the oil cup 4.

[0059] like Figure 2 As shown, the front side of the casing 1 forms a vertical plane, and the flap 3 is a flat structure extending vertically. When fully closed, the flap 3 is vertical and parallel to the wall, presenting a flat appearance. This makes the range hood more compact when not in use, achieving a thinner body size and reducing space occupation. Furthermore, from the front, the flap 3 appears as a complete flat structure with no visible gaps, facilitating daily cleaning and enhancing the overall aesthetics. Its appearance is clearly distinguishable from traditional or other range hood structures in the industry. This design not only improves the user experience but also avoids the cleaning difficulties caused by the complex structure of traditional range hoods.

[0060] like Figure 1As shown, the smoke collection chamber 2 has a smoke inlet 221 on its front side. When the smoke collection chamber 2 is fully open, the smoke inlet 221 is tilted downwards. At this time, the angle between the front side of the smoke collection chamber 2 and the vertical direction can be selected from 20° to 40°, preferably 30°. This allows the smoke inlet 221 to face the stove and has a larger smoke collection area, effectively improving the smoke collection efficiency and helping to prevent oil fumes from escaping. When the flap 3 is fully closed, the flap 3 covers the smoke inlet 221, making it aesthetically pleasing and neat.

[0061] The top of the flap 3 is rotatably connected to the top of the smoke collection chamber 2. This arrangement ensures that when the flap 3 is fully opened, its bottom end opens relative to the smoke collection chamber 2, thereby better absorbing the generated fumes. Optionally, the top of the flap 3 can be rotatably connected to the smoke collection chamber 2 via a hinge or latch; no specific limitation is made here.

[0062] Furthermore, when the flap 3 and the smoke collection chamber 2 are fully opened, an angle is formed between the flap 3 and the smoke collection chamber 2, forming a smoke gathering area. The angle ranges from 55° to 95°, preferably 77°. At this time, the smoke gathering effect of the smoke gathering area is better.

[0063] In other words, when in the open state, the smoke collection chamber 2 extends relative to the housing 1, achieving the first-level smoke collection function. Then, the flap 3 flips open relative to the smoke collection chamber 2, further expanding the smoke collection range and forming a superimposed smoke collection effect of "1+1>2". This synergistic effect not only improves the smoking efficiency but also achieves a combination of a small body size and a large smoke collection area, realizing a large smoke collection size with a relatively small smoke collection mechanism.

[0064] In this embodiment, as Figure 1 As shown, inner glass 5 is installed at both ends of the front side of the smoke collection chamber 2. Each inner glass 5 extends outward in the left and right directions, but does not exceed the left and right sides of the flap 3. The inner glass 5 on both sides not only improves the aesthetics, but also increases the smoke collection area and reduces the escape of oil fumes.

[0065] like Figure 3 As shown, the smoke collection chamber 2 includes a main body 21 and an oil filter 22. An installation port is provided on the front side of the main body 21, and the oil filter 22 covers the installation port. Multiple smoke inlets 221 are provided on the oil filter 22. Cooking fumes contain a large number of grease particles. If the grease enters the fan directly, it will adhere to the motor, blades, and other core components, leading to increased operating resistance, increased noise, and even damage. The oil filter 22, as the first line of defense, filters these oil droplets through dense pores, preventing them from directly entering the range hood or adhering to the fan blades. This reduces the accumulation of grease on internal parts, resulting in cleaner filtered air and effectively reducing grease contamination of the internal ducts of the range hood and the external environment.

[0066] Optionally, in this embodiment, the oil filter 22 is magnetically attached to the main body 21 of the smoke collection chamber for easy disassembly and individual cleaning. In other optional embodiments, the oil filter 22 can also be detachably installed using snap-fit ​​or screw connection, and no specific limitation is made here.

[0067] Optionally, two mounting ports are provided on the front side of the smoke collection chamber body 21, and the two mounting ports are arranged at intervals along the left and right direction. Each mounting port is equipped with an oil filter 22. In this way, each oil filter 22 can correspond to one stove, achieving precise smoke extraction and improving smoke extraction efficiency.

[0068] like Figure 6 As shown, the drive mechanism includes a first drive assembly 6 and a second drive assembly 7. When opening or closing, the first drive assembly 6 drives the flap 3 to flip relative to the smoke collection chamber 2, and the second drive assembly 7 drives the smoke collection chamber 2 to move relative to the housing 1. By driving the flap 3 and the smoke collection chamber 2 independently with two sets of drive assemblies, the stability of the movement of the flap 3 and the smoke collection chamber 2 can be ensured, and it is also beneficial to reduce the longitudinal dimension of the range hood and save kitchen space.

[0069] Specifically, the first drive assembly 6 is installed in the middle of the smoke collection chamber 2, and the second drive assembly 7 is installed on the left and right sides inside the housing 1. By reasonably setting the positions of the first drive assembly 6 and the second drive assembly 7, the space occupied by the two can be reasonably allocated, and by arranging the first drive assembly 6 and the second drive assembly 7 along the transverse side of the smoke machine, it is beneficial to reduce the longitudinal dimension of the smoke machine.

[0070] like Figure 6 As shown, the first drive assembly 6 includes a first motor 61 and a first swing arm assembly 62. The first motor 61 is disposed inside the smoke collection chamber 2. One end of the first swing arm assembly 62 is connected to the output shaft of the first motor 61, and the other end passes through the smoke collection chamber 2 and is hinged to the back of the flap 3. When the output shaft of the first motor 61 rotates, it drives the first swing arm assembly 62 to rotate, and the first swing arm assembly 62 drives the flap 3 to flip relative to the smoke collection chamber 2 to open or close. This drive structure has the advantages of simple structure, high control precision, safety and reliability, compact structure, and low maintenance cost. Optionally, in other embodiments, the first motor 61 can be replaced with a drive cylinder.

[0071] Specifically, such as Figure 6As shown, the first swing arm assembly 62 includes a first swing arm 621 and a second swing arm 622. One end of the first swing arm 621 is connected to the output shaft of the first motor 61, and the other end is hinged to one end of the second swing arm 622. The other end of the second swing arm 622 passes through the front side of the smoke collection chamber 2 and is hinged to the back of the flap 3. Specifically, when the output shaft of the first motor 61 rotates, the first motor 61 drives the first swing arm 621 to rotate, the first swing arm 621 drives the second swing arm 622 to rotate, and the second swing arm 622 drives the flap 3 to rotate, thereby opening or closing. By adopting the above-described swing arm structure, when the flap 3 is closed, the first swing arm 621 and the second swing arm 622 are folded, occupying little space. When the flap 3 is open, the first swing arm 621 and the second swing arm 622 extend to a longer length, thereby opening the flap 3 to a specific angle to meet a larger smoke collection area.

[0072] Furthermore, combined Figures 6 to 8 The smoke collection chamber 2 has a protective cavity 24 at its rear and a through hole 211 at its front that communicates with the protective cavity 24. A first motor 61 is installed inside the protective cavity 24, as is a first swing arm 621. A second swing arm 622 passes through the through hole 211 and connects to the back of the flap 3. By installing the first motor 61 inside the protective cavity 24 at the rear of the smoke collection chamber 2, the fumes are isolated, minimizing direct contact between the fumes and the first motor 61, thus extending the service life of the first motor 61 and consequently extending the service life of the side-suction range hood.

[0073] Furthermore, such as Figure 1 As shown, an elastic seal 212 is used to seal the perforation 211. The elastic seal 212 can be made of rubber. The elastic seal 212 has a slit. The second swing arm 622 passes through the slit and connects to the back of the flap 3. The slit seal is wrapped around the outside of the second swing arm 622 to prevent oil fumes from entering the protective cavity 24 through the perforation 211 and adhering to the first motor 61, which would increase its operating resistance, increase noise, or even damage it.

[0074] Furthermore, such as Figure 7 As shown, in the left-right direction, the protective cavity 24 is located in the middle of the smoke collection cavity 2, and the second swing arm 622 is connected to the middle of the back of the flap 3. This arrangement ensures that the flap 3 is subjected to uniform force, allowing the left and right sides of the flap 3 to push out synchronously when it opens, preventing jamming and ensuring the synchronicity and stability of the movement.

[0075] Furthermore, combined Figure 8The first drive assembly 6 also includes a mounting bracket 63, which includes a first plate 631, a second plate 632, and a third plate 633. The first plate 631 covers the upper opening of the protective cavity 24. The second plate 632 is connected to the first plate 631 at an angle and is located at the rear opening of the protective cavity 24. The second plate 632 abuts against the rear side of the smoke collection cavity 2 and is fastened. The third plate 633 is connected to the second plate 632 and extends into the protective cavity 24 and is fastened to the first motor 61.

[0076] First, the mounting bracket 63 is used to fix the first motor 61 and covers the opening of the protective cavity 24 to isolate the oil fumes. Second, since the flap 3 is heavy, if the mounting bracket 63 is not strong enough, the mounting bracket 63 and the entire smoke collection cavity 2 will deform during the opening of the flap 3. Therefore, by abutting and installing the second plate 632 of the mounting bracket 63 against the rear side of the smoke collection cavity 2, its structural strength can be guaranteed.

[0077] Specifically, such as Figure 8 As shown, the second plate 632 covers part of the rear opening of the protective cavity 24, and the rear opening of the protective cavity 24 not covered by the second plate 632 forms a clearance opening 25. At least part of the first motor 61 is directly opposite the second plate 632 to provide protection, and the first swing arm assembly 62 is directly opposite the clearance opening 25.

[0078] When the flap 3 is fully closed, the hinged parts of the first swing arm 621 and the second swing arm 622 after folding can extend from the clearance opening 25 to provide clearance. Secondly, when the range hood malfunctions and the flap 3 cannot be opened, the rear plate 15 of the range hood can be disassembled after the range hood is removed from the wall. The screw connecting the first swing arm 621 to the output shaft of the first motor 61 is exposed at the clearance opening 25. At this time, the worker can loosen this screw with a wrench to release the constraint on the flap 3 and allow the flap 3 to open smoothly for subsequent maintenance operations. If the first motor 61 malfunctions, the mounting bracket 63 can be removed to repair or replace the first motor 61, making machine maintenance convenient.

[0079] In one optional embodiment, the smoke collection chamber 2 can only rotate relative to the housing 1.

[0080] In an optional embodiment, the smoke collection chamber 2 can only slide relative to the housing 1 in the front-rear direction.

[0081] In one optional embodiment, the smoke collection chamber 2 can rotate and slide relative to the housing 1. Specifically, the smoke collection chamber 2 can generate a sliding displacement in the horizontal or inclined direction while rotating relative to the housing 1.

[0082] In this embodiment, when the smoke collection chamber 2 is opened, the smoke collection chamber 2 flips outward relative to the housing 1 and generates an upward sliding displacement; conversely, when the smoke collection chamber is closed, the smoke collection chamber 2 flips inward relative to the housing 1 and generates a downward sliding displacement.

[0083] When the smoke collection chamber 2 is opened, it can not only rotate relative to the shell 1, but also extend the smoke collection area forward by sliding upward at an angle, thereby expanding the coverage of the smoke collection area. As the smoke collection chamber 2 extends forward, the flap 3 unfolds and adjusts its angle to further increase the smoke collection area, effectively improving the smoke collection efficiency, helping to prevent oil fumes from escaping, and improving the cleanliness and air quality of the kitchen. At the same time, the upward sliding of the smoke collection chamber 2 can also drive the flap 3 to rise as a whole, avoiding obstruction of vision and head bumping.

[0084] In this embodiment, as Figure 7 As shown, the second driving assembly 7 is used to drive the smoke collection chamber 2 to rotate relative to the housing 1 while generating a sliding displacement in the tilt direction. Specifically, the second driving assembly 7 includes a rotating component 71, a first guide component 72, and a second guide component 73. The rotating component 71 is used to drive the smoke collection chamber 2 to rotate, and the smoke collection chamber 2 slides in cooperation with the housing 1 through the first guide component 72 and the second guide component 73.

[0085] The flipping component 71 drives the smoke collection chamber 2 to flip, providing the smoke collection chamber 2 with the power to open or close, causing the smoke collection chamber 2 to extend outward from the housing 1 and reach the smoke extraction position. The smoke collection chamber 2 slides with the housing 1 through the first guide component 72 and the second guide component 73. The first guide component 72 and the second guide component 73 limit the sliding trajectory of the smoke collection chamber 2, ensuring that the smoke collection chamber 2 is stable and does not shake during the sliding process. Through the guidance of the guide components, the smoke collection chamber 2 can flip outward relative to the housing 1 when it is opened, and at the same time generate an outward sliding displacement in the tilt direction. Therefore, the smoke collection area extends forward, the smoke collection area is larger, the smoke collection efficiency is effectively improved, and it helps to prevent the escape of oil fumes and improve the air quality in the kitchen.

[0086] Specifically, such as Figure 6 and Figure 9 As shown, the flipping component 71 includes a second motor 711, a drive shaft 713, and two sets of second swing arm assemblies 712. The second motor 711 is connected to the housing 1. The drive shaft 713 extends in the left and right direction. One end of the drive shaft 713 is fixedly connected to the output shaft of the second motor 711, for example, by welding or screw fixing, and the other end passes through the housing 1. The two sets of second swing arm assemblies 712 are respectively connected to the left and right sides of the smoke collection chamber 2 and are simultaneously fixedly mounted on the drive shaft 713.

[0087] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate. The transmission shaft 713 drives the two sets of second swing arms 712 to rotate synchronously. The two sets of second swing arms 712 cause the smoke collection chamber 2 to flip relative to the housing 1, thus opening or closing it. In this way, the second motor 711 drives the two sets of second swing arms 712 to rotate synchronously through the transmission shaft 713, which ensures that the left and right sides of the smoke collection chamber 2 move synchronously when opening or closing, ensuring the synchronicity and stability of the movement.

[0088] Specifically, such as Figure 9 and Figure 11 As shown, the second swing arm assembly 712 includes a third swing arm 7121, a fourth swing arm 7122, and a swing arm bracket 7123. The third swing arm 7121 is fixedly mounted on the drive shaft 713, for example, by welding or screw fixing. The fourth swing arm 7122 is hinged to the third swing arm 7121. The swing arm bracket 7123 is hinged to the fourth swing arm 7122 and fixedly connected to the smoke collection chamber 2.

[0089] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate. The transmission shaft 713 then drives the third swing arm 7121 to rotate. The third swing arm 7121 transmits power sequentially through the fourth swing arm 7122 and the swing arm bracket 7123, ultimately driving the smoke collection chamber 2 to move. By adopting the above-mentioned swing arm structure, when the smoke collection chamber 2 is closed, the third swing arm 7121 and the fourth swing arm 7122 fold, occupying little space. When the smoke collection chamber 2 is open, the third swing arm 7121 and the fourth swing arm 7122 extend, thereby opening the smoke collection chamber 2 to a specific angle to meet a larger smoke collection area.

[0090] Optionally, such as Figure 6 and Figure 7 As shown, the housing 1 also includes inner side plates 12 located on the left and right sides. The inner side plates 12 are located inside the outer side plates 11, and the outer side plates 11 enclose a sealed chamber. The second motor 711 is located in one of the sealed chambers and is fixed to the inner side plate 12. By installing the second motor 711 in the sealed chamber, it can isolate oil fumes, minimize direct contact between oil fumes and the second motor 711, and extend the service life of the second motor 711.

[0091] Optionally, the smoke collection chamber 2 is provided with a first guide component 72 and a second guide component 73 on both the left and right sides to ensure that the smoke collection chamber 2 moves smoothly without shaking during the sliding process.

[0092] Specifically, such as Figure 10As shown, the first guide component 72 is located below the second guide component 73. The first guide component 72 includes a guide bracket 721 and a guide shaft 722. The guide bracket 721 is fixed to the outer side of the inner side plate 12, and the guide shaft 722 is fixed to the side of the smoke collection chamber 2. A guide hole 7211 is provided on the guide bracket 721, and the guide shaft 722 is rotatably connected to the guide hole 7211 and can slide along the guide hole 7211. The second guide component 73 includes a guide rail 732 and a slider 731. The guide rail 732 is fixed to the inner side of the inner side plate 12, and the slider 731 can slide along the guide rail 732. The end of the slider 731 is rotatably connected to the smoke collection chamber 2.

[0093] When the second motor 711 drives the smoke collection chamber 2 to rotate via the second swing arm assembly 712, the smoke collection chamber 2 drives the slider 731 and the guide shaft 722 to move. The slider 731 rotates relative to the smoke collection chamber 2 around the hinge point while sliding along the guide rail 732. The guide shaft 722 rotates in the guide hole 7211 while sliding along the guide hole 7211. Through the coordinated action of the slider 731 and the guide shaft 722, the composite motion path of the entire smoke collection chamber 2 is determined, ensuring that the smoke collection chamber 2 is stable and does not shake during the sliding process.

[0094] Furthermore, such as Figure 10 and Figure 11 As shown, the smoke collection chamber 2 also includes a chamber reinforcement 23. The left and right ends of the smoke collection chamber body 21 are respectively connected to the chamber reinforcement 23. The guide shaft 722, the slider 731, and the swing arm bracket 7123 are all connected to the chamber reinforcement 23. The chamber reinforcement 23 strengthens the structural strength of the smoke collection chamber body 21 and prevents deformation.

[0095] Among them, the hinge axis of the swing arm bracket 7123 and the fourth swing arm 7122 is coaxial with the hinge axis of the slider 731 and the cavity reinforcement 23 to meet the motion trajectory requirements.
