Description

Technical Field

[0001] This utility model relates to the technical field of range hoods, and in particular to an oil mesh structure and a range hood. Background Technology

[0002] In existing near-suction range hoods, the oil filter structure is often used to filter oil fumes and regulate airflow. Manually adjustable oil filter structures primarily rely on the relative sliding of the inner and outer oil filters to open and close the air inlet.

[0003] Currently, most handles with oil mesh structures protrude from the surface of the outer oil mesh. On the one hand, to ensure that the baffle of the range hood does not interfere with the handle when closed, a larger gap needs to be reserved between the baffle and the outer oil mesh, which will increase the space occupied by the oil mesh structure in the thickness direction, which goes against the current design trend of making range hoods thinner and more compact. On the other hand, oil fumes tend to accumulate on the handle surface, resulting in problems such as oil accumulation and dripping on the handle surface. Utility Model Content

[0004] Therefore, it is necessary to provide a more compact oil mesh structure and range hood that is less prone to oil accumulation, addressing the current problems of large space occupation and easy oil accumulation in the handle.

[0005] This application provides an oil mesh structure, including a handle, a connector, an outer oil mesh and an inner oil mesh stacked along a first direction, wherein the inner oil mesh is slidably connected to the back of the outer oil mesh along a second direction to have an open and a closed state, wherein, in the open state, the first ventilation hole on the inner oil mesh is directly opposite to the second ventilation hole on the outer oil mesh; in the closed state, the inner oil mesh is misaligned and blocks the second ventilation hole;

[0006] The connector is connected to the inner oil mesh and extends along a first direction to the front of the outer oil mesh. The connector is movable relative to the outer oil mesh to drive the inner oil mesh to slide. The handle is located on the front of the outer oil mesh and is detachably connected to the connector to drive the connector to move relative to the outer oil mesh.

[0007] In one embodiment, the connector is flush with the front side of the outer oil mesh.

[0008] In one embodiment, the handle includes two grip portions symmetrically arranged about the axis of the connector, the grip portions being flat.

[0009] In one embodiment, the connector includes a lever and a connecting part rotatably connected to the outer oil mesh. The connecting part passes through the outer oil mesh and the inner oil mesh. One end of the connecting part located on the front of the outer oil mesh is connected to the handle, and the other end is fixed to the lever.

[0010] A limiting piece is fixed on the back of the inner oil mesh, and the handle can drive the lever to rotate to drive the limiting piece, so that the inner oil mesh switches between open and closed states along the second direction.

[0011] In one embodiment, the handle further includes a bushing, a washer, and a screw. The bushing and the washer are fitted onto the connecting part. One end of the bushing abuts against the outer oil mesh. The paddle is fitted onto the connecting part through its own limiting hole. The outer wall of the connecting part abuts against the inner wall of the limiting hole in the circumferential direction to restrict the paddle from rotating relative to the connecting part.

[0012] The washer is sandwiched between the bushing and the lever, and the screw is threaded to the connecting part in a first direction to cooperate with the washer to restrict the movement of the lever in the first direction.

[0013] In one embodiment, the inner oil mesh has a T-shaped hole extending through it in a first direction, and the connecting part extends through the T-shaped hole in a second direction. The connecting part is in a detached state, in which the projection of the paddle in the first direction is completely located within the extension of the T-shaped hole in a third direction.

[0014] In one embodiment, one of the handle and the connecting part is provided with a snap-fit ​​part, and the other part is provided with a snap-fit ​​groove corresponding to the snap-fit ​​part. The snap-fit ​​part can be inserted into the snap-fit ​​groove to restrict the relative rotation between the two.

[0015] In one embodiment, the handle is provided with the snap-fit ​​portion, and the connecting portion has a snap-fit ​​groove corresponding to the snap-fit ​​portion.

[0016] In one embodiment, the connector is fixed to the inner oil mesh.

[0017] This application also provides a range hood, including a range hood body and the aforementioned oil mesh structure, wherein the outer oil mesh is fixed to the inner wall of the air intake of the range hood body.

[0018] The above-mentioned oil mesh structure adopts a handle-separation design, which breaks down the traditional handle into a connector and a handle that is detachably connected to the connector. The connector passes through the oil mesh to serve as a transmission medium, while the handle is used to drive the connector to move, so as to ensure the normal operation of the ventilation hole opening and closing function.

[0019] Based on this, the detachable handle design allows the oil mesh structure of this application to eliminate the traditional handle protrusion height by removing the handle, thereby effectively reducing the gap required between the smoke baffle and the outer oil mesh, which is in line with the trend of thin and light design. In addition, the handle can also avoid the risk of oil accumulation and dripping after removal, and facilitates the cleaning of the handle separately.

[0020] In other words, the oil mesh structure of this application achieves the dual effects of reducing thickness and preventing oil accumulation while maintaining the normal operation of the oil mesh opening and closing function, precisely matching the needs of modern kitchen cooking equipment for thinness and maintenance-free operation.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0035] For ease of description, in this application, the direction of the air intake axis of the range hood is defined as the first direction, the air inlet side of the air intake is defined as the front of the oil mesh structure, the corresponding opposite side is defined as the back side, the length direction of the projection of the range hood air intake along the first direction is defined as the second direction, and the width direction of the projection of the range hood air intake along the first direction is defined as the third direction.

[0036] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, this application first provides an oil mesh structure, including a handle 10, a connector 40, an outer oil mesh 20 and an inner oil mesh 30 stacked along a first direction. The inner oil mesh 30 is slidably connected to the back of the outer oil mesh 20 along a second direction to have open and closed states. In the open state, the first ventilation hole 31 on the inner oil mesh 30 is directly opposite to the second ventilation hole 21 on the outer oil mesh 20. In the closed state, the inner oil mesh 30 is offset and blocks the second ventilation hole 21. The connector 40 is connected to the inner oil mesh 30 and extends along the first direction to the front of the outer oil mesh 20. The connector 40 is movable relative to the outer oil mesh 20 to drive the inner oil mesh 30 to slide. The handle 10 is located on the front of the outer oil mesh 20 and is detachably connected to the connector 40 to drive the connector 40 to move relative to the outer oil mesh 20.

[0037] In this application, by adopting a handle separation design, the traditional handle is split into a connector 40 and a handle 10 that is detachably connected to the connector 40. The connector 40 passes through the oil mesh to serve as a transmission medium, while the handle 10 is used to drive the connector 40 to move, so as to ensure the normal operation of the ventilation hole opening and closing function.

[0038] Based on this, the detachable handle 10 allows the oil mesh structure of this application to eliminate the traditional handle protrusion height by removing the handle 10, thereby effectively reducing the gap required between the smoke baffle and the outer oil mesh 20, which is in line with the trend of thin and light design. In addition, after the handle 10 is removed, the risk of oil accumulation and dripping on the handle 10 can be avoided, and the handle 10 can be cleaned separately.

[0039] In other words, the oil mesh structure of this application achieves the dual effects of reducing thickness and preventing oil accumulation while maintaining the normal operation of the oil mesh opening and closing function, precisely matching the needs of modern kitchen cooking equipment for thinness and maintenance-free operation.

[0040] Specifically, the handle 10 is connected to the inner oil mesh 30. This connection can be achieved by means of a snap-fit ​​or other means, or by the handle 10 being directly fixed to the inner oil mesh 30, or by other means, as long as the handle 10 can drive the inner oil mesh 30 to slide relative to the outer oil mesh 20. In addition, the handle 10 can move relative to the outer oil mesh 20. This movement can be sliding, rotating, or a combination of sliding and rotating movements. Examples of these movements will not be listed here.

[0041] In some embodiments, the connector 40 is flush with the front side of the outer oil mesh 20.

[0042] It is understandable that by designing the connector 40 to be flush with the front of the outer oil mesh 20, its protrusion on the front of the outer oil mesh 20 can be completely eliminated. In other words, when the handle 10 is removed, there is no protrusion on the front of the outer oil mesh 20, thereby further reducing the gap that needs to be reserved between the smoke baffle and the outer oil mesh 20, and reducing the possibility of oil stains accumulating on the connector 40.

[0043] Please refer to Figure 4 As shown, in some embodiments, the handle 10 includes two grip portions 11 symmetrically arranged around the axis of the connector 40. The grip portions 11 are flat to facilitate gripping by the user and improve the grip comfort when the user uses the handle 10 to adjust the state of the inner oil filter 30.

[0044] Please combine Figure 5 as well as Figure 6 As shown, in some embodiments, the connector 40 includes a lever 42 and a connecting part 41 rotatably connected to the outer oil mesh 20. The connecting part 41 passes through the outer oil mesh 20 and the inner oil mesh 30. One end of the connecting part 41 located on the front of the outer oil mesh 20 is connected to the handle 10, and the other end is fixed to the lever 42.

[0045] The inner oil mesh 30 has a limiting piece 32 fixed on its back. The handle 10 can drive the paddle 42 to rotate to drive the limiting piece 32, so that the inner oil mesh 30 switches between open and closed states along the second direction.

[0046] By clamping the inner oil mesh 30 between the paddle 42 and the outer oil mesh 20, the paddle 42 can not only cooperate with the limiting piece 32 to adjust the sliding of the inner oil mesh 30, but also form a constraint inside the inner oil mesh 30 to cooperate with the outer oil mesh 20 to restrict the movement of the inner oil mesh 30 in the first direction, thereby improving the rigidity inside the inner oil mesh 30 and reducing the risk of sliding deformation, avoiding the situation where the handle 10 and the outer oil mesh 20 interfere and rub against each other due to the deformation of the inner oil mesh 30.

[0047] Furthermore, the limiting clamping structure achieved by the lever 42 and the outer oil mesh 20 only increases the thickness of the lever 42 along the first direction, and occupies less space along the first direction, making it more suitable for compact and lightweight designs.

[0048] Specifically, the outer oil mesh 20 and the inner oil mesh 30 form a sliding pair along the second direction. The connecting part 41 is fixed to the lever 42 so that the lever 42 can be driven to move through the connecting part 41. The limiting piece 32 is fixed to the back of the inner oil mesh 30. By the lever 42 abutting against the limiting piece 32, the movement of the lever 42 is converted into the sliding of the inner oil mesh 30 along the second direction. That is to say, when the user drives the handle 10, the lever 42 pushes the inner oil mesh 30 to slide along the second direction through the limiting piece 32, thereby adjusting the overlapping state of the first ventilation hole 31 and the second ventilation hole 21.

[0049] In some embodiments, the paddle 42 and the connecting portion 41 are detachably fixed (e.g., by a snap-fit, thread, etc.) to reduce assembly difficulty and increase maintainability.

[0050] Please combine Figure 5 as well as Figure 6 As shown, in some embodiments, the handle 10 also includes a bushing 43, a washer 44 and a screw 45. The bushing 43 and the washer 44 are sleeved on the connecting part 41. One end of the bushing 43 abuts against the outer oil mesh 20. The paddle 42 is sleeved on the connecting part 41 through its own limiting hole. The outer wall of the connecting part 41 abuts against the inner wall of the limiting hole in the circumferential direction to restrict the paddle 42 from rotating relative to the connecting part 41.

[0051] The washer 44 is sandwiched between the bushing 43 and the lever 42, and the screw 45 is threadedly connected to the connecting part 41 in the first direction to cooperate with the washer 44 to restrict the movement of the lever 42 in the first direction.

[0052] The rigid positioning of the limiting hole of the paddle 42 and the outer wall of the connecting part 41, as well as the adjustable clamping structure of the gasket 44 and the screw 45, ensure double fixation between the paddle 42 and the connecting part 41 in both the circumferential and axial directions. This prevents the connection between the paddle 42 and the handle 10 from easily becoming loose in the circumferential direction, leading to transmission failure, or from increasing the gap or shifting of the components due to axial movement.

[0053] Specifically, the limiting hole of the paddle 42 cooperates with the outer wall of the connecting part 41 to restrict circumferential rotation. At the same time, the threaded connection between the connecting part 41 and the screw adjusts the clamping force between the paddle 42 and the inner oil mesh 30, balancing the sliding friction and structural stability.

[0054] More specifically, the outer wall of the connecting part 41 has a non-circular cross-section (such as D-shaped, polygonal, etc.) to cooperate with the limiting hole to restrict circumferential rotation.

[0055] Please combine Figure 5 as well as Figure 6 As shown, in some embodiments, the inner oil mesh 30 is provided with a T-shaped hole 33 through the first direction, and the connecting part 41 passes through the extension of the T-shaped hole 33 along the second direction. The connecting part 40 is in a disassembled state. In the disassembled state, the projection of the paddle 42 along the first direction is completely located in the extension of the T-shaped hole 33 along the third direction.

[0056] It should be understood that by turning the handle 10, the paddle 42 can be rotated to the disassembly state. At this time, the projection of the paddle 42 along the first direction is completely located within the extension of the T-hole 33 along the third direction. In other words, the paddle 42 can pass through the T-hole 33 along the first direction. At this time, the inner oil mesh 30 and the outer oil mesh 20 can be directly separated along the first direction, which effectively reduces the difficulty of assembling and disassembling the oil mesh structure of this application.

[0057] In some embodiments, the T-hole 33 has chamfers on both sides along the first direction to facilitate the removal and insertion of the paddle 42.

[0058] Specifically, two limiting pieces 32 are symmetrically fixed on the back of the inner oil mesh 30 with the T-shaped hole 33 extending along the third direction as the center. Each limiting piece 32 has an L-shaped cross section parallel to the first direction and the third direction.

[0059] The portion of the limiting piece 32 that contacts the inner oil mesh 30 is located between the paddle 42 and the inner oil mesh 30 along the first direction to prevent the paddle 42 from being obstructed from rotating due to scratching the back of the inner oil mesh 30 during rotation. The other portion of the limiting piece 32 that contacts the paddle 42 is perpendicular to the direction of the paddle 42 to prevent the paddle 42 from generating a component force in other directions when driving the limiting piece 32, thereby improving the smoothness of the sliding of the paddle 42 driving the inner oil mesh 30.

[0060] In some embodiments, the thickness of the gasket 44 is greater than the thickness of the portion of the limiting piece 32 that adheres to the inner oil mesh 30 along the first direction.

[0061] It is easy to understand that the thickness of the gasket 44 is greater than the thickness of the contact part of the limiting piece 32, so that when the screw 45 is tightened, the pressure is applied to the gasket 44 first rather than the limiting piece 32. The assembly tolerance is compensated by the elastic deformation of the gasket 44, while limiting the interference between the lever 42 and the bottom wall of the limiting piece 32 due to the clamping force.

[0062] If the shim is too thin, the lever 42 may excessively compress the contact part of the limiting piece 32 after the screw is tightened, which may cause interference. Therefore, by limiting the thickness of the shim 44 to be greater than the thickness of the contact part of the limiting piece 32, the clamping force is ensured to be evenly distributed, while avoiding interference between the lever 42 and the limiting piece 32, extrusion deformation, etc.

[0063] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, one of the handle 10 and the connecting part 41 is provided with a snap-fit ​​part 12, and the other is provided with a snap-fit ​​groove 411 corresponding to the snap-fit ​​part 12. The snap-fit ​​part 12 can be inserted into the snap-fit ​​groove 411 to restrict the relative rotation between the two.

[0064] It is understandable that the engagement between the snap-fit ​​part 12 and the snap-fit ​​groove 411 can prevent the handle 10 from slipping between the connecting part 41, ensuring that the opening and closing action of the inner oil screen 30 can be executed accurately. Moreover, the snap-fit ​​method does not require additional fasteners compared to other connection methods, making assembly relatively convenient.

[0065] Specifically, the outer wall of the snap-fit ​​part 12 has a non-circular cross-section (such as D-shaped, polygonal, etc.) to cooperate with the snap-fit ​​groove 411 to restrict circumferential rotation.

[0066] Of course, in other embodiments, the handle 10 and the connecting part 41 can also be connected by other commonly used detachable connection methods such as bolt connection or snap connection, as long as the connecting part 41 can be rotated by the handle 10. This application will not give examples of each of them here.

[0067] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, the handle 10 is provided with a snap-fit ​​part 12, and the connecting part 41 is provided with a snap-fit ​​groove 411 corresponding to the snap-fit ​​part 12.

[0068] The air intake of the range hood is mostly set at an angle, that is, the outer oil screen 20 is mostly set at an angle. The snap-fit ​​groove 411 is opened in the connecting part 41 so that the opening of the snap-fit ​​groove 411 faces downward in the first direction. Even if there is some oil in the snap-fit ​​groove 411, it can be drained by gravity, avoiding the situation where the snap-fit ​​groove 411 is stuck due to the accumulation of oil.

[0069] In addition, the snap-fit ​​groove 411 with its opening facing downwards allows the user to see the opening directly, which can effectively reduce the difficulty of installing the handle 10.

[0070] In some embodiments, the connector 40 is fixed to the inner oil mesh 30, and the outer oil mesh 20 has a through groove. The connector 40 passes through the through groove and can move in the second direction within the through groove. After the user connects the handle 10 to the connector 40, the user can drive the connector 40 and the inner oil mesh 30 to slide in the second direction through the handle 10, thereby realizing the switching of the open and closed state of the inner oil mesh 30.

[0071] Please combine Figure 3 as well as Figure 7 As shown, in some embodiments, the oil mesh structure further includes at least two sets of magnetic attraction components 50. Each set of magnetic attraction components 50 includes a magnet 51 and a first support member 52. The first support member 52 includes a support portion 521 and a limiting post 522. The front side of the support portion 521 forms a point contact with the outer oil mesh 20 and the back side forms a receiving cavity. The limiting post 522 is fixed to the bottom wall of the receiving cavity. The magnet 51 is sleeved on the limiting post 522 and located in the receiving cavity. The front side of the inner oil mesh 30 has a plurality of grooves 34 corresponding to the magnetic attraction components 50. The support portion 521 is embedded in the corresponding groove 34. The limiting post 522 penetrates the through hole in the bottom wall of the groove 34.

[0072] Specifically, after the magnet 51 is inserted into the limiting post 522, it is magnetically attracted to the groove 34. The limiting post 522 is inserted into the through hole in the bottom wall of the groove 34 to form a radial rigid limit. The magnet 51 is also magnetically attracted to the outer oil mesh 20 to improve the connection stability between the inner oil mesh 30 and the outer oil mesh 20 along the first direction. In addition, the contact area between the front of the support part 521 and the outer oil mesh 20 is only a point to greatly reduce the sliding resistance.

[0073] The point contact design can effectively reduce the sliding friction resistance between the outer oil mesh 20 and the support part 521, thus making it smoother for the user to adjust the inner oil mesh 30 through the handle 10.

[0074] In some embodiments, the front of the support portion 521 is designed as a spherical surface, and the depth of the groove 34 along the first direction is slightly less than the thickness of the support portion 521 along the first direction, so that the support portion 521 can partially protrude from the front of the inner oil mesh 30 and form point contact with the back of the outer oil mesh 20.

[0075] Furthermore, in some embodiments, the oil mesh structure is provided with four sets of magnetic attraction components 50, which are correspondingly embedded in the four grooves 34 at the four corners of the inner oil mesh 30.

[0076] Furthermore, the magnets 51 of the two sets of magnetic attraction components 50 located on the upper side are larger in volume than the magnets 51 of the two sets of magnetic attraction components 50 located on the lower side.

[0077] Please refer to Figure 3 As shown, in some embodiments, the edges of both the inner oil mesh 30 and the outer oil mesh 20 are provided with flanges that bend towards the back.

[0078] Specifically, the inner oil mesh 30 and the outer oil mesh 20 are connected by a flange along a third direction. Through the flange design of the inner oil mesh 30 and the outer oil mesh 20, the overall rigidity of the oil mesh structure is improved, while also constraining the sliding direction and stabilizing the gap size, ensuring the smoothness of the inner oil mesh 30 sliding along the second direction.

[0079] Please refer to Figure 3 As shown, in some embodiments, the outer oil mesh 20 has a second support member 22 protruding inward on the flange along a third direction, and the second support member 22 makes point contact with the flange of the inner oil mesh 30.

[0080] Traditional flanged structures, which slide through surface contact (such as direct contact of the entire flange), tend to have an excessively large friction area, resulting in a large starting torque and requiring more effort from the user. In contrast, this application adds a second support member 22 to the flanges on both sides of the outer oil mesh 20 along a third direction, which reduces the contact area while providing multi-point local support, thus balancing the conflict between rigidity enhancement and frictional resistance reduction.

[0081] Specifically, the second support member 22 can be hemispherical, curved, or other shapes, as long as it can make point contact with the flange of the inner oil mesh 30. Each flange of the outer oil mesh 20 is provided with 3 to 5 equally spaced second support members 22. This ensures both uniform support and minimizes friction. Even if one second support member 22 fails due to wear, the remaining second support members 22 can still maintain the positioning and support of the inner oil mesh 30, extending its service life. Preferably, each flange of the outer oil mesh 20 is provided with 4 equally spaced second support members 22.

[0082] Please refer to Figure 3 As shown, the outer oil mesh 20 has a secondary flange along the bottom edge of the third direction. When it is necessary to remove the inner oil mesh 30 and the outer oil mesh 20, first use the bottom flange of the outer oil mesh 20 as the rotation center, and then rotate the top of the inner oil mesh 30 to the back side to remove the inner oil mesh 30. During this process, the secondary flange at the bottom of the outer oil mesh 20 can play a supporting role, so as to facilitate the removal of the inner oil mesh 30 and the outer oil mesh 20 and their separate cleaning.

[0083] The assembly process is the reverse of the disassembly process, and will not be described in detail here.

[0084] Please refer to Figure 3 As shown, in some embodiments, the flanges of the outer oil mesh 20 and the inner oil mesh 30 are kept as straight as possible. Preferably, the flange of the inner oil mesh 30 is a continuous, unbroken ring to improve the rigidity of the outer oil mesh 20 and the inner oil mesh 30, and to effectively reduce the gap between the inner oil mesh 30 and the outer oil mesh 20 compared to cases with more breaks.

[0085] This application also provides a range hood, including a range hood body and the aforementioned oil mesh structure, wherein the outer oil mesh 20 is fixed to the inner wall of the air intake of the range hood body.

[0086] Specifically, two sets of oil mesh structures are provided inside the smoke inlet along the second direction.
