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 the air intake. Among them, the manually adjustable oil filter structure mainly relies on the relative sliding of the inner and outer oil filters to realize the opening and closing function of the air intake; traditional manually adjustable oil filters mostly use manual pushing of the handle to move the inner oil filter, so that the inner and outer ventilation holes are aligned or misaligned to realize the adjustment of the air intake.

[0003] However, in actual use, this type of structure is prone to damage to the coating due to repeated sliding as the handle is in direct contact with the surface of the outer oil mesh. This not only affects the appearance but also accelerates the corrosion and aging of the oil mesh, reducing its service life. In addition, the handle's movement trajectory is exposed to the outside, and the long-term accumulation of scratches will form obvious wear areas, further weakening the product's aesthetics. Utility Model Content

[0004] Therefore, it is necessary to address the current problem that the handle is easily scratched by the outer oil filter, affecting its service life and appearance consistency, and to provide an oil filter structure and range hood that can reduce scratches and improve appearance consistency.

[0005] This application provides an oil mesh structure, including a handle, 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 handle is connected to the inner oil mesh and protrudes from the front of the outer oil mesh. The handle can move relative to the outer oil mesh to drive the inner oil mesh to slide. The protruding part of the handle includes a blocking part and a support part fixed to the back of the blocking part. The support part is in contact with the front of the outer oil mesh and forms a contact trajectory on the surface of the outer oil mesh as the handle moves. The projection of the contact trajectory along the first direction is always completely covered by the blocking part.

[0007] In one embodiment, the handle further includes a connecting part rotatably connected to the outer oil mesh, the connecting part passing through the outer oil mesh and the inner oil mesh, one end being fixed to the shielding part, and the other end being fixed with a paddle;

[0008] A limiting piece is fixed on the back of the inner oil mesh. The rotation of the connecting part can drive the lever to drive the limiting piece, so that the inner oil mesh switches between open and closed states along the second direction.

[0009] In one embodiment, the projection of the blocking portion along the first direction is circular, and the projection of the supporting portion along the first direction is annular.

[0010] In one embodiment, the support portion includes a first support portion and a second support portion, wherein the first support portion is fixed to the outer edge of the back side of the shielding portion, and the second support portion is fixed to the outer peripheral surface of the connecting portion.

[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 handle also includes a washer and a screw. The washer 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 washer to restrict the movement of the paddle in the first direction.

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

[0014] In one embodiment, the oil mesh structure further includes an oil cup fixed relative to the outer oil mesh and located at the bottom of the outer oil mesh, and the handle further includes a grip portion fixed to the front of the shielding portion, the thickness of the grip portion gradually decreasing towards the oil cup along the first direction to form an oil guiding surface on the front.

[0015] In one embodiment, the edge of the oil guiding surface near the oil cup is flush with the front edge of the shielding portion.

[0016] In one embodiment, the front edge of the shielding portion is rounded.

[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 aforementioned oil mesh structure, by setting the support part to be attached to the front of the outer oil mesh to form a contact surface, can actively force the friction pressure to be distributed to a larger contact area, disperse the friction force, and reduce the possibility of the handle scratching the outer oil mesh. In addition, by establishing a projection constraint relationship between the shielding part and the contact trajectory, the contact trajectory formed by the support part on the surface of the outer oil mesh is always within the vertical projection range of the shielding part, realizing optical shielding of the contact trajectory. Thus, even if the contact trajectory has minor scratches, it will not be directly exposed to the user's field of vision, thereby improving the appearance consistency of the oil mesh structure of this application.

[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, 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, so as to have an open and closed state, wherein, 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 misaligned and blocks the second ventilation hole 21;

[0037] The handle 10 is connected to the inner oil mesh 30 and protrudes from the front of the outer oil mesh 20. The handle 10 can move relative to the outer oil mesh 20 to drive the inner oil mesh 30 to slide. The protruding part of the handle 10 includes a blocking part 11 and a support part 12 fixed to the back of the blocking part 11. The support part 12 is in contact with the front of the outer oil mesh 20 and forms a contact track on the surface of the outer oil mesh 20 as the handle 10 moves. The projection of the contact track along the first direction is always completely covered by the blocking part 11.

[0038] In this application, by setting the support part 12 to be in contact with the front of the outer oil mesh 20 to form a contact surface, the friction pressure can be actively and forcibly distributed to a larger contact area, dispersing the friction force and reducing the possibility of the handle 10 scratching the outer oil mesh 20. In addition, by establishing a projection constraint relationship between the shielding part 11 and the contact trajectory, the contact trajectory formed by the support part 12 on the surface of the outer oil mesh 20 is always within the vertical projection range of the shielding part 11, achieving optical shielding of the contact trajectory. This ensures that even if the contact trajectory is slightly scratched, it will not be directly exposed to the user's field of vision, thereby improving the appearance consistency of the oil mesh structure of this application.

[0039] Specifically, the handle 10 is connected to the inner oil mesh 30. This can be done by connecting the handle 10 to the inner oil mesh 30 through a snap-fit ​​or other means, or by fixing the handle 10 directly to the inner oil mesh 30, or by connecting it to the inner oil mesh 30 in other ways. As long as the handle 10 can drive the inner oil mesh 30 to slide relative to the outer oil mesh 20, it is acceptable.

[0040] More specifically, 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 motions, which will not be listed in this application.

[0041] Please combine Figure 4 , Figure 5 as well as Figure 6 As shown, in some embodiments, the handle 10 also includes a connecting part 13 that is rotatably connected to the outer oil mesh 20. The connecting part 13 passes through the outer oil mesh 20 and the inner oil mesh 30, with one end fixed to the blocking part 11 and the other end fixed with a paddle 14.

[0042] The inner oil mesh 30 has a limiting piece 32 fixed on its back. The rotation of the connecting part 13 can drive the lever 14 to drive the limiting piece 32, so that the inner oil mesh 30 switches between open and closed states along the second direction.

[0043] By clamping the inner oil mesh 30 between the paddle 14 and the outer oil mesh 20, the paddle 14 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.

[0044] Furthermore, the limiting clamping structure achieved by the lever 14 and the outer oil mesh 20 only increases the thickness of the lever 14 along the first direction, and occupies less space along the first direction, making it more suitable for compact and lightweight designs.

[0045] Specifically, the outer oil mesh 20 and the inner oil mesh 30 form a sliding pair along the second direction. The connecting part 13 is fixed to the lever 14 so that the lever 14 can be driven to move through the connecting part 13. The limiting piece 32 is fixed to the back of the inner oil mesh 30. By the lever 14 abutting against the limiting piece 32, the movement of the lever 14 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 14 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.

[0046] In some embodiments, the paddle 14 and the connecting portion 13 are detachably fixed (e.g., by a snap-fit, thread, etc.) to reduce assembly difficulty and increase maintainability.

[0047] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the projection of the blocking portion 11 along the first direction is circular, and the projection of the supporting portion 12 along the first direction is annular.

[0048] The circular shielding part 11, together with the annular support part 12, can form a bearing system. When rotating, the pressure distribution on the contact surface is axially symmetrical, which improves the support stability of the handle 10 during rotation, further disperses the frictional force of the support part 12 on the external oil mesh 20, and reduces the possibility of scratches.

[0049] In some other embodiments, the part of the support 12 that contacts the outer oil mesh 20 is made of rubber or other flexible material.

[0050] Please refer to Figure 5 As shown, in some embodiments, the support portion 12 includes a first support portion 121 and a second support portion 122. The first support portion 121 is fixed to the outer edge of the back side of the shielding portion 11, and the second support portion 122 is fixed to the outer peripheral surface of the connecting portion 13.

[0051] The first support portion 121 located on the outer edge of the back of the shielding portion 11 is used to support the shielding portion 11 along the first direction, so as to avoid abnormal noise or even scratches caused by the shielding portion 11 shaking and deforming and hitting the outer oil mesh 20. In addition, the second support portion 122 fixed to the outer peripheral surface of the connecting portion 13 can enhance the support effect of the shielding portion 11 on the one hand, and improve the connection strength between the shielding portion 11 and the connecting portion 13 on the other hand, thereby improving the overall structural rigidity of the handle 10.

[0052] Please combine Figure 4 , Figure 5 as well as Figure 6 As shown, in some embodiments, the paddle 14 is sleeved on the connecting part 13 through its own limiting hole 141, and the outer wall of the connecting part 13 abuts against the inner wall of the limiting hole 141 in the circumferential direction to restrict the paddle 14 from rotating relative to the connecting part 13.

[0053] The handle 10 also includes a washer 15 and a screw 17. The washer 15 is sleeved on the connecting part 13 and located between the paddle 14 and the inner oil mesh 30. The screw 17 is threaded to the connecting part 13 in a first direction to cooperate with the washer 15 to restrict the movement of the paddle 14 in the first direction.

[0054] The rigid positioning of the limit hole 141 of the paddle 14 and the outer wall of the connecting part 13, as well as the adjustable clamping structure of the gasket 15 and the screw 17, ensure that the paddle 14 and the connecting part 13 are double fixed in the circumferential and axial directions. This prevents the connection between the paddle 14 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.

[0055] Specifically, the limiting hole 141 of the lever 14 cooperates with the outer wall of the connecting part 13 to restrict circumferential rotation. At the same time, the threaded connection between the connecting part 13 and the screw adjusts the clamping force between the lever 14 and the inner oil mesh 30, balancing the sliding friction and structural stability.

[0056] More specifically, the outer wall of the connecting part 13 has a non-circular cross-section (such as D-shaped, polygonal, etc.) to cooperate with the limiting hole 141 to restrict circumferential rotation.

[0057] Please refer to Figure 6 As shown, in some embodiments, the inner oil mesh 30 is provided with a T-shaped hole 33, the connecting part 13 extends through the T-shaped hole 33 along the second direction, and the lever 14 is in a disassembled state. In the disassembled state, the projection of the lever 14 along the first direction is completely located within the extension of the T-shaped hole 33 along the third direction.

[0058] It should be understood that by turning the handle 10, the paddle 14 can be rotated to the disassembly state. At this time, the projection of the paddle 14 along the first direction is completely located within the extension of the T-hole 33 along the third direction. In other words, the paddle 14 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.

[0059] 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 14.

[0060] 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.

[0061] The portion of the limiting piece 32 that contacts the inner oil mesh 30 is located between the paddle 14 and the inner oil mesh 30 along the first direction to prevent the paddle 14 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 14 is perpendicular to the direction of the paddle 14 to prevent the paddle 14 from generating a component force in other directions when driving the limiting piece 32, thereby improving the smoothness of the sliding of the paddle 14 driving the inner oil mesh 30.

[0062] In some embodiments, the thickness of the gasket 15 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.

[0063] It is easy to understand that the thickness of the gasket 15 is greater than the thickness of the contact part of the limiting piece 32, so that when the screw 17 is tightened, the pressure is applied to the gasket 15 first rather than the limiting piece 32. The assembly tolerance is compensated by the elastic deformation of the gasket 15, while limiting the interference between the lever 14 and the bottom wall of the limiting piece 32 due to the clamping force.

[0064] If the shim is too thin, the lever 14 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 15 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 14 and the limiting piece 32, extrusion deformation, etc.

[0065] Please combine Figure 1 , Figure 7 as well as Figure 8 As shown, in some embodiments, the oil mesh structure also includes an oil cup 40 that is fixed relative to the outer oil mesh 20 and located at the bottom of the outer oil mesh 20, and the handle 10 also includes a grip portion 16 fixed to the front of the shielding portion 11. The thickness of the grip portion 16 gradually decreases towards the oil cup 40 along the first direction to form an oil guiding surface 161 on the front.

[0066] For the oil adhering to the handle 10 area, the oil is guided into the oil cup 40 by the oil guiding surface 161 with decreasing thickness and gravity, so as to avoid the oil accumulating at the handle 10 position and causing the handle 10 to be restricted in movement.

[0067] Preferably, in some embodiments, the edge of the oil guiding surface 161 near the oil cup 40 is flush with the front edge of the shielding portion 11. More preferably, in some embodiments, the front edge of the shielding portion 11 is rounded. This is to better guide the oil adhering to the shielding portion 11 and the gripping portion 16 to the surface of the outer oil mesh 20, and to allow the oil to flow into the oil cup 40 under the action of gravity.

[0068] Please combine Figure 2 as well as Figure 9As 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] Please refer to Figure 2 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.

[0075] 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.

[0076] Please refer to Figure 2As 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.

[0077] 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.

[0078] 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.

[0079] Please refer to Figure 2 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.

[0080] The assembly process is the reverse of the disassembly process, and will not be described in detail here.

[0081] Please refer to Figure 2 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.

[0082] Please refer to Figure 7 As shown, 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.

[0083] Specifically, two sets of oil mesh structures are provided inside the smoke inlet along the second direction.

[0084] Please combine Figure 2 as well as Figure 7As shown, the outer oil mesh 20 is also fixed with a latch 60 located on the upper side of the T-shaped hole 33 along the third direction, which is used to snap and fix it to the range hood body.

[0085] 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.

[0086] 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.
