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 mesh structure is often used to filter oil fumes and regulate the air intake. 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 intake.

[0003] However, in traditional manually adjustable oil mesh structures, mounting holes for sliding handles are usually required on the surface of the outer oil mesh, which leads to a decrease in the structural strength of the outer oil mesh, easy residue of oil in the additional openings, and affects the uniformity of appearance. Utility Model Content

[0004] Therefore, it is necessary to address the issue that the handle mounting holes in the current manually adjustable oil mesh structure affect the strength of the outer oil mesh structure, and to provide an oil mesh structure and range hood that can meet the sliding requirements without the need for additional handle mounting holes.

[0005] This application provides an oil mesh structure, including an outer oil mesh and an inner oil mesh stacked along a first direction. 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. 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 inner oil mesh is fixed with a handle, which passes through the second ventilation hole and protrudes from the front of the outer oil mesh.

[0007] In one embodiment, the handle is fixed to the edge of the first ventilation hole.

[0008] In one embodiment, the handle is fixed to the edge of the first vent along a second direction.

[0009] In one embodiment, the handle is integrally formed with the inner oil mesh.

[0010] 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 includes a first oil guide portion, the thickness of which gradually decreases towards the oil cup along a first direction.

[0011] In one embodiment, the handle further includes a second oil guide located on top of the first oil guide, the thickness of the second oil guide gradually increasing towards the oil cup along the first direction.

[0012] In one embodiment, the first oil guide portion and the second oil guide portion are symmetrically arranged vertically along a third direction.

[0013] In one embodiment, the inner oil mesh is fixed with a plurality of handles, each handle passing through a different second ventilation hole.

[0014] In one embodiment, the inner oil mesh is fixed with two handles, the two handles respectively passing through two second ventilation holes at both ends along the second direction.

[0015] 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.

[0016] The aforementioned oil mesh structure integrates the functions of the separate handle mounting hole and ventilation hole in traditional oil stain structures by having the handle pass through the second ventilation hole and protrude from the front of the outer oil mesh. The second ventilation hole of the outer oil mesh is not only used for the passage of oil fumes, but also serves as a channel for the handle to move, thereby avoiding the addition of unnecessary openings to the outer oil mesh and preserving the integrity of the outer oil mesh. On the one hand, it significantly enhances its structural strength and resistance to deformation, and on the other hand, it can reduce the dead corners where oil stains accumulate, making it easier to wipe and clean.

[0030] 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.

[0031] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, this application provides an oil mesh structure, including 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 an open and a closed state. 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. The inner oil mesh 30 is fixed with a handle 32, which passes through the second ventilation hole 21 and protrudes from the front of the outer oil mesh 20.

[0032] In this application, by having the handle 32 pass through the second ventilation hole 21 and protrude from the front of the outer oil mesh 20, the functions of the independent handle mounting hole and ventilation hole in the traditional oil stain structure are integrated. The second ventilation hole 21 of the outer oil mesh 20 is not only used for the passage of oil fumes, but also serves as the movement channel of the handle 32. This avoids adding unnecessary openings to the outer oil mesh 20, preserves the integrity of the outer oil mesh 20, significantly enhances its structural strength and resistance to deformation, and also reduces dead corners for oil stain accumulation, making it easier to wipe and clean.

[0033] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the handle 32 is fixed to the edge of the first ventilation hole 31; the edge structure of the first ventilation hole 31 itself is used as a support point, which not only retains the original function of the first ventilation hole 31, but also forms a stable force fulcrum through local reinforcement of the edge; that is to say, on the one hand, it can avoid the handle 32 from blocking the airflow channel of the first ventilation hole 31 and ensure ventilation efficiency, and on the other hand, it can enhance the rigidity of the combination of the handle 32 and the inner oil mesh 30.

[0034] In some embodiments, the connection between the handle 32 and the inner oil mesh 30 is made with a curved edge transition to reduce oil accumulation.

[0035] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the handle 32 is fixed to the edge of the first ventilation hole 31 along the second direction, that is, the handle 32 extends along the third direction; so that when the user operates the handle 32 to push or pull, the direction of the force applied by the user to the surface of the handle 32 is parallel to the sliding direction of the inner oil mesh 30, so as to eliminate the influence of the lateral component force on the sliding process, avoid sliding deviation, and reduce the probability of jamming.

[0036] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the handle 32 and the inner oil mesh 30 are integrally formed (e.g., injection molding or stamping) to reduce assembly steps, lower costs, and also avoid stress concentration at connection points, thereby improving structural strength.

[0037] Preferably, after forming the first ventilation hole 31 with the handle 32 on the inner oil mesh 30 by stamping or laser cutting, the handle 32 is bent at ninety degrees by stamping or bending to minimize processing steps and reduce costs.

[0038] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, the oil mesh structure also includes an oil cup 10 that is fixed relative to the outer oil mesh 20 and located at the bottom of the outer oil mesh 20, and the handle 32 includes a first oil guiding portion 321, the thickness of which gradually decreases towards the side closer to the oil cup 10 along the first direction.

[0039] The first oil guide part 321 of the handle 32 is designed as an inclined surface with a thickness that gradually decreases towards the oil cup 10 along the first direction. Through the slope design and gravity working together, the attached oil droplets flow naturally along the inclined surface to the area of ​​the oil cup 10, avoiding the accumulation or dripping of oil stains on the handle or the outer oil mesh 20.

[0040] In some embodiments, the surface of the handle 32 is also provided with an oleophobic coating or an oil-guiding groove, which can accelerate the sliding of oil droplets to optimize the oil guiding performance.

[0041] Please refer to Figure 2 As shown, in some embodiments, the handle 32 also includes a second oil guiding part 322 located at the top of the first oil guiding part 321. The thickness of the second oil guiding part 322 gradually increases towards the oil cup 10 along the first direction. That is, a reverse slope that gradually increases in thickness towards the oil cup 10 along the first direction is designed on the upper side of the handle 32.

[0042] The second oil guide section 322 with the first oil guide section 321 forms a complementary oil guide channel through the reverse inclined surface. When the handle 32 is close to the upper side and oil adheres, the second oil guide section 322 uses surface tension and gravity to guide the oil droplets to flow towards the first oil guide section 321 and finally into the oil cup 10.

[0043] In some embodiments, the second oil guiding part 322 and the first oil guiding part 321 are connected by an arc surface to ensure that there are no breaks in the oil guiding surface.

[0044] Please refer to Figure 2 As shown, in some embodiments, the first oil guiding part 321 and the second oil guiding part 322 are symmetrically arranged vertically along a third direction. That is, the second oil guiding part 322 and the first oil guiding part 321 form a complementary oil guiding channel through the reverse slope. It should be understood that the vertical symmetrical design allows oil droplets to be guided to the oil cup 10 through the symmetrical slope, regardless of whether the oil droplets are attached to the second oil guiding part 322 or the first oil guiding part 321. This makes the oil guiding effect of the handle 32 independent of the spatial posture, thereby improving the consistency of the oil guiding function of the handle 32 in different postures.

[0045] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the inner oil mesh 30 is fixed with a plurality of handles 32, each handle 32 passing through a different second ventilation hole 21.

[0046] It's easy to understand that a single handle 32 is prone to uneven force distribution when pushing or pulling the inner oil mesh 30, leading to sliding jamming or structural deformation, especially when oil accumulates, increasing operating resistance. However, by fixing multiple handles 32 to the inner oil mesh 30 and having them pass through different second ventilation holes 21, multiple fulcrums can be formed to distribute the pushing and pulling force. The coordinated action of multiple handles 32 ensures that the inner oil mesh 30 is subjected to uniform force as a whole, avoiding localized stress concentration, while also reducing the operating force required for a single handle 32 and improving sliding smoothness.

[0047] For the best option, please refer to the following: Figure 1 as well as Figure 3As shown, in some embodiments, the inner oil mesh 30 is fixed with two handles 32, and the two handles 32 pass through two second ventilation holes 21 at both ends along the second direction.

[0048] Please combine Figure 3 , Figure 5 as well as Figure 6 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.

[0049] 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.

[0050] 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 32.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Please refer to Figure 5 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.

[0055] 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.

[0056] Please refer to Figure 5 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.

[0057] 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.

[0058] 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.

[0059] Please refer to Figure 5 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.

[0060] The assembly process is the reverse of the disassembly process, and will not be described in detail here.

[0061] Please refer to Figure 5 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.

[0062] Please refer to Figure 4As 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.

[0063] Specifically, two sets of oil mesh structures are provided inside the smoke inlet along the second direction.

[0064] Please combine Figure 2 as well as Figure 5 As shown, a snap-fit ​​clip 50 is also fixed on the outer oil mesh 20 for engaging and fixing with the range hood body.

[0065] 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.

[0066] 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.
