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 close-range suction range hoods, the oil mesh structure is often used to filter oil fumes and regulate the air intake.

[0003] Among them, the manually adjustable oil mesh structure mainly relies on the relative sliding of the inner and outer oil meshes to realize the opening and closing function of the air inlet. In order to ensure the positional stability of the inner oil mesh after sliding, the manually adjustable oil mesh structure usually uses an external slide rail or independent limiting component (such as a buckle or protrusion structure) to constrain the sliding path of the inner oil mesh.

[0004] However, most of these independent limiting structures can only constrain the edge of the oil mesh. The oil mesh is thin and lacks rigidity, making it prone to deformation or displacement under frequent operation. Therefore, it is easy for the sliding resistance to increase or even jam, making it difficult to ensure long-term stable operation.

[0005] In addition, this type of independent limiting structure not only requires additional assembly steps, but also increases the space occupied by the oil mesh component in the thickness direction, which goes against the current design trend of making range hoods thinner and more compact. Utility Model Content

[0006] Therefore, it is necessary to address the issue that the current independent limiting structure of the oil mesh component does not solve the problem of jamming caused by oil mesh deformation and is not conducive to the compact design of range hoods. A new oil mesh structure and range hood that can reduce oil mesh deformation and are more suitable for the compact design of range hoods should be provided.

[0007] This application provides an oil mesh structure, including an adjustment component, 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;

[0008] The adjustment assembly includes a handle and a paddle. The paddle is movably disposed on the back of the inner oil mesh, and the handle is movably disposed on the front of the outer oil mesh. One of the paddle and the handle passes through the outer oil mesh and the inner oil mesh along a first direction to be fixed to the other, so as to clamp the inner oil mesh between the paddle and the outer oil mesh.

[0009] The inner oil mesh is also fixed with a limiting piece. The movement of the handle can drive the paddle to drive the limiting piece, so that the inner oil mesh switches between open and closed states along the second direction.

[0010] In one embodiment, the handle includes an operating part located on the front of the outer oil mesh and a connecting part passing through the outer oil mesh and the inner oil mesh, the connecting part being rotatably connected to the outer oil mesh, and the paddle being detachably fixed to the connecting part.

[0011] In one embodiment, the paddle is fitted onto the connecting portion through its own limiting hole, and the outer wall of the connecting portion abuts against the inner wall of the limiting hole in the circumferential direction to restrict the paddle from rotating relative to the connecting portion.

[0012] The adjustment assembly also includes a shim and a screw. The shim is sleeved on the connecting part and located between the paddle and the inner oil mesh. The screw is threaded to the connecting part in a first direction to cooperate with the shim to restrict the movement of the paddle in the first direction.

[0013] In one embodiment, the limiting piece has a U-shaped cross-section along the first direction and the third direction, and the U-shaped bottom wall of the limiting piece is located between the paddle and the inner oil mesh along the first direction.

[0014] In one embodiment, the thickness of the gasket is greater than the thickness of the U-shaped bottom wall of the limiting piece along the first direction.

[0015] In one embodiment, the oil mesh structure further includes at least two sets of magnetic attraction components. Each set of magnetic attraction components includes a magnet and a first support member. The first support member includes a support part and a limiting post. The front side of the support part forms a point contact with the outer oil mesh and the back side forms a receiving cavity. The limiting post is fixed to the bottom wall of the receiving cavity. The magnet is sleeved on the limiting post and located inside the receiving cavity.

[0016] The inner oil mesh has multiple grooves on its front side corresponding to the magnetic suction component. The support part is embedded in the corresponding groove, and the limiting post passes through the through hole in the bottom wall of the groove.

[0017] In one embodiment, both the inner and outer oil mesh edges are provided with flanges that bend towards the back.

[0018] In one embodiment, the outer oil mesh has a second support member protruding inward on the flange along a third direction, and the second support member makes point contact with the flange of the inner oil mesh.

[0019] In one embodiment, the flange of the inner oil mesh is a continuous, unbroken ring.

[0020] This application also includes a range hood, comprising 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.

[0021] The above-mentioned oil mesh structure, by clamping the inner oil mesh between the lever and the outer oil mesh, allows the lever to not only cooperate with the limiting piece to achieve sliding adjustment of the inner oil mesh, but also to form a constraint inside the inner oil mesh to cooperate with the outer oil mesh to restrict the movement of the inner oil mesh along the first direction, thereby improving the rigidity inside the inner oil mesh and reducing the risk of sliding deformation, achieving adjustment and limiting without additional space occupation;

[0022] Furthermore, the limiting and clamping structure achieved by the lever and the outer oil mesh only increases the thickness of the lever along the first direction, and occupies less space along the first direction, making it more suitable for compact and lightweight designs.

[0038] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, this application provides an oil mesh structure, including an adjustment component 10, an outer oil mesh 20 and an inner oil mesh 30 stacked along a first direction, the inner oil mesh 30 being 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 the second ventilation hole 21 on the outer oil mesh 20; in the closed state, the inner oil mesh 30 is misaligned and blocks the second ventilation hole 21. The adjustment component 10 includes a handle 11 and a lever 12. The paddle 12 is movably disposed on the back of the inner oil mesh 30, and the handle 11 is movably disposed on the front of the outer oil mesh 20. One of the paddle 12 and the handle 11 passes through the outer oil mesh 20 and the inner oil mesh 30 along the first direction and is fixed to the other, so as to clamp the inner oil mesh 30 between the paddle 12 and the outer oil mesh 20. A limiting piece 32 is also fixed on the inner oil mesh 30. The movement of the handle 11 can drive the paddle 12 to drive the limiting piece 32, so that the inner oil mesh 30 switches between open and closed states along the second direction.

[0039] In this application, by clamping the inner oil mesh 30 between the lever 12 and the outer oil mesh 20, the lever 12 can not only cooperate with the limiting piece 32 to achieve sliding adjustment 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, achieving adjustment and limiting without additional space occupation;

[0040] Furthermore, the limiting clamping structure achieved by the lever 12 and the outer oil mesh 20 only increases the thickness of the lever 12 along the first direction, and occupies less space along the first direction, making it more suitable for compact and lightweight designs.

[0041] Specifically, the outer oil mesh 20 and the inner oil mesh 30 form a sliding pair along the second direction. The handle 11 is fixed to the paddle 12 so that the paddle 12 can be driven to move by the handle 11. The limiting piece 32 is fixed to the back of the inner oil mesh 30. By the paddle 12 abutting against the limiting piece 32, the movement of the paddle 12 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 11, the paddle 12 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.

[0042] More specifically, the above-mentioned activities can be sliding, rotating, or a combination of sliding and rotating. This application will not give examples of each of them, as long as they can cause the contact point between the paddle 12 and the limiting piece 32 to be displaced in the second direction.

[0043] Please combine Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, the handle 11 includes an operating part 111 located on the front of the outer oil mesh 20 and a connecting part 112 passing through the outer oil mesh 20 and the inner oil mesh 30. The connecting part 112 is rotatably connected to the outer oil mesh 20, and the paddle 12 is detachably fixed to the connecting part 112.

[0044] In this application, the detachable fixing (such as buckle, thread, etc.) between the lever 12 and the connecting part 112 can reduce the assembly difficulty and increase maintainability. The rotational connection between the connecting part 112 and the outer oil mesh 20 reduces frictional resistance, making it easier for the user to adjust the opening and closing state through the operating part 111.

[0045] Furthermore, the handle 11 is divided into an operating part 111 and a connecting part 112. The connecting part 112 passes through the outer oil mesh 20 and the inner oil mesh 30 to form a rotation fulcrum, which transmits the rotational action to the paddle 12. It should be understood that the distance between the point of force application when the user rotates the operating part 111 and the rotation fulcrum is the lever arm length. Under the condition that the torque is constant, the longer the lever arm, the smaller the force required.

[0046] In other words, in this application, the connecting part 112 forms a rotating pair with the outer oil screen 20, and the force required to open and close the inner oil screen 30 can be reduced by adjusting the length of the operating part 111, thereby reducing the manual load on the user during use.

[0047] Specifically, both the outer oil mesh 20 and the inner oil mesh 30 have through openings for the connecting part 112 to pass through. The connecting part 112 is rotatably connected to the inner wall of the through opening of the outer oil mesh 20, and the through opening of the inner oil mesh 30 is elongated in the second direction to avoid interference when the inner oil mesh 30 slides relative to the connecting part 112 in the second direction.

[0048] It is worth mentioning that in some existing technologies, the operating structure such as the handle 11 is directly fixed to the inner oil mesh 30 and protrudes from the front of the outer oil mesh 20. In this type of structure, the handle 11 and the inner oil mesh 30 are an integral structure. When the user drives the inner oil mesh 30 to move, the position of the handle 11 is the force point of the integral structure, while the contact position between the inner oil mesh 30 and the outer oil mesh 20 is the support point of the integral structure. Since the force point is located on the front of the outer oil mesh 20 and the support point is located inside the outer oil mesh 20, there must be a gap between the force point and the support point along the first direction. As a result, the driving force applied by the user to the handle 11 will inevitably have a component torque along the third direction.

[0049] In other words, when the user drives the inner oil network 30 to move, the inner oil network 30 tends to deflect in a third direction, which makes it easy for the inner oil network 30 to interfere with the outer oil network 20.

[0050] In some embodiments, the contact point between the paddle 12 and the limiting piece 32 is located in the same plane as the contact point between the second support 22 and the flange of the inner oil mesh 30, and this plane is parallel to the second direction.

[0051] It is understandable that since the handle 11 and the paddle 12 are fixed, the handle 11 and the paddle 12 form an integral structure. When the handle 11 is driven to move, the contact point between the paddle 12 and the limiting piece 32 is the actual force point of the inner oil mesh 30, while the contact point between the second support member 22 and the flange of the inner oil mesh 30 is the support point of the inner oil mesh 30. By designing the force point and the support point of the inner oil mesh 30 to be located in the same plane parallel to the second direction, the possibility of the inner oil mesh 30 being deflected by the driving force can be effectively avoided, reducing the interference and jamming between the inner oil mesh 30 and the outer oil mesh 20, and ensuring that the oil mesh structure can operate effectively for a long time.

[0052] Please combine Figure 3 as well as Figure 4As shown, in some embodiments, the paddle 12 is sleeved on the connecting part 112 through its own limiting hole 121, and the outer wall of the connecting part 112 abuts against the inner wall of the limiting hole 121 in the circumferential direction to restrict the paddle 12 from rotating relative to the connecting part 112.

[0053] The adjustment assembly 10 also includes a shim 13 and a screw (not shown). The shim 13 is sleeved on the connecting part 112 and located between the paddle 12 and the inner oil mesh 30. The screw is threaded to the connecting part 112 in a first direction to cooperate with the shim 13 to restrict the movement of the paddle 12 in the first direction.

[0054] The rigid positioning of the limit hole 121 of the paddle 12 and the outer wall of the connecting part 112, as well as the adjustable clamping structure of the gasket 13 and the screw, ensures double fixation between the paddle 12 and the connecting part 112 in both the circumferential and axial directions. This prevents the connection between the paddle 12 and the handle 11 from easily becoming loose in the circumferential direction, leading to transmission failure, or from increasing the gap or misalignment of the components due to axial movement.

[0055] Specifically, the limiting hole 121 of the lever 12 cooperates with the outer wall of the connecting part 112 to restrict circumferential rotation. At the same time, the clamping force between the lever 12 and the inner oil mesh 30 is adjusted through the threaded connection of the washer 13 and the screw, thus balancing the sliding friction and structural stability.

[0056] More specifically, the outer wall of the connecting part 112 has a non-circular cross-section (such as D-shaped, polygonal, etc.) to cooperate with the limiting hole 121 to restrict circumferential rotation.

[0057] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the limiting piece 32 has a U-shaped cross section parallel to the first direction and the third direction, and the U-shaped bottom wall of the limiting piece 32 is located between the paddle 12 and the inner oil mesh 30 along the first direction, so as to avoid the paddle 12 being obstructed from rotating due to scratching the back of the inner oil mesh 30 during the rotation of the paddle 12.

[0058] In addition, the two side walls of the U-shaped limiting piece 32 are perpendicular to the direction of the lever 12, which avoids the generation of component forces in other directions when the lever 12 drives the limiting piece 32, and improves the sliding stability of the lever 12 driving the inner oil mesh 30.

[0059] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the thickness of the gasket 13 is greater than the thickness of the U-shaped bottom wall of the limiting piece 32 along the first direction.

[0060] It is easy to understand that the thickness of the shim 13 is greater than the thickness of the U-shaped bottom wall of the limiting piece 32, so that when the screw is tightened, the pressure is applied to the shim 13 first rather than the limiting piece 32. The assembly tolerance is compensated by the elastic deformation of the shim 13, while limiting the interference between the lever 12 and the bottom wall of the limiting piece 32 due to the clamping force.

[0061] If the shim is too thin, the lever 12 may excessively compress the U-shaped bottom wall of the limiting piece 32 after the screw is tightened, which may cause interference. Therefore, by limiting the thickness of the shim 13 to be greater than the thickness of the U-shaped bottom wall, the clamping force is ensured to be evenly distributed, while avoiding interference between the lever 12 and the limiting piece 32, extrusion deformation, etc.

[0062] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the oil mesh structure further includes at least two sets of magnetic assemblies 40. Each set of magnetic assemblies 40 includes a magnet 41 and a first support member 42. The first support member 42 includes a support portion 421 and a limiting post 422. The front of the support portion 421 forms a point contact with the outer oil mesh 20 and the back forms a receiving cavity. The limiting post 422 is fixed to the bottom wall of the receiving cavity. The magnet 41 is sleeved on the limiting post 422 and located in the receiving cavity. The front of the inner oil mesh 30 has a plurality of grooves 33 corresponding to the magnetic assemblies 40. The support portion 421 is embedded in the corresponding groove 33. The limiting post 422 penetrates the through hole in the bottom wall of the groove 33.

[0063] Specifically, after the magnet 41 is inserted into the limiting post 422, it is magnetically attracted to the groove 33. The limiting post 422 is inserted into the through hole in the bottom wall of the groove 33 to form a radial rigid limit. The magnet 41 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 421 and the outer oil mesh 20 is only a point to greatly reduce the sliding resistance.

[0064] The point contact design can effectively reduce the sliding friction resistance between the outer oil mesh 20 and the support part 421, thus making it smoother for the user to adjust the inner oil mesh 30 through the handle 11.

[0065] In some embodiments, the front of the support portion 421 is designed as a spherical surface, and the depth of the groove 33 along the first direction is slightly less than the thickness of the support portion 421 along the first direction, so that the support portion 421 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.

[0066] Furthermore, in some embodiments, the oil mesh structure is provided with four sets of magnetic attraction components 40, which are correspondingly embedded in the four grooves 33 at the four corners of the inner oil mesh 30.

[0067] Furthermore, the magnets 41 of the two sets of magnetic attraction components 40 located on the upper side are larger in volume than the magnets 41 of the two sets of magnetic attraction components 40 located on the lower side.

[0068] Please refer to Figure 4 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.

[0069] 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.

[0070] Furthermore, in some embodiments, the projection of the paddle 12 and the limiting piece 32 along the second or third direction is located inside the flange of the inner oil mesh 30. That is to say, the adjustment component 10 in this application will not increase the space occupied by the oil mesh structure along the first direction, and can better adapt to the compact range hood structure.

[0071] Please combine Figure 4 as well as Figure 6 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.

[0072] 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.

[0073] 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.

[0074] Please combine Figure 2 as well as Figure 4 As shown, the outer oil mesh 20 has a secondary flange along the bottom edge in the third direction. When it is necessary to remove the inner oil mesh 30 and the outer oil mesh 20, first unscrew the screws and remove the handle 11, the paddle 12 and the washer 13. Then, using the bottom flange of the outer oil mesh 20 as the rotation center, 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.

[0075] The assembly process is the reverse of the disassembly process, and will not be described in detail here.

[0076] Please refer to Figure 4 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.

[0077] Please refer to Figure 7 As shown, this application also includes a range hood, comprising 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.

[0078] Specifically, two sets of oil mesh structures are provided inside the smoke inlet along the second direction.

[0079] Please refer to Figure 2 as well as Figure 4 As shown, the outer oil mesh 20 is also fixed with a latch 50 located on the upper side of the adjustment component 10 along a third direction, which is used to snap and fix it to the range hood body.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
