[0035] The present application is described in detail below. Examples of embodiments of the present application are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. In addition, if the detailed description of the known technology is not necessary for the features of the present application shown, it will be omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0036] Those skilled in the art will understand that, unless otherwise stated, the singular forms "a," "an," "said," and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of this application refers to the presence of the stated features, elements, and / or components, but does not exclude the presence or addition of one or more other features, elements, components, and / or groups thereof. The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0037] like Figure 1-2 As shown, an embodiment of the present application provides a connector, which mainly includes a connector body 1 and a diverter structure 2. The connector body 1 includes a flap connecting section 11 and a drive device connecting section 12 connected at an angle. The flap connecting section 11 is provided with an oil accumulation area 100. The diverter structure 2 is provided in the oil accumulation area 100. The diverter structure 2 is protruding or recessed from the connector body 1, guiding the oil at the connection between the connector body 1 and the diverter structure 2 to flow toward the diverter structure 2.

[0038] like Figure 1-3 As shown in Figures 5, 7, and 8, in this embodiment, the connector body 1 is a rod-shaped structure. The connector body 1 is bent to form a flap connection section 11 and a drive device connection section 12. The flap connection section 11 is arranged to be inclined forward and downward relative to the drive device connection section 12. The extension directions of the flap connection section 11 and the drive device connection section 12 intersect, so that the flap connection section 11 can move in the designed direction under the drive of the drive device 4 to push or pull the flap 3 to flip.

[0039] The oil accumulation area 100 is where condensed oil on the connector body 1 flows and accumulates under the action of gravity. For example, if the connector is arranged horizontally, the oil accumulation areas 100 are provided on the sides and bottom of the connector body 1. The top of the connector body 1 is typically not the oil accumulation area 100. Oil on the top of the connector body 1 flows downward under the action of gravity and cannot accumulate at the top, thus failing to form an oil accumulation area 100. The flap connecting section 11 is inclined more downwardly than the drive device connecting section 12, so the oil accumulation area 100 is located on the flap connecting section 11.

[0040] Due to the concave-convex relationship between the diverter structure 2 and the connector body 1, as well as the distribution area of ​​the oil accumulation area 100, there are various embodiments. For example, the diverter structure 2 protrudes from the connector body 1 and is only provided on the side of the connector body 1; the diverter structure 2 protrudes from the connector body 1 and is only provided on the bottom of the connector body 1; the diverter structure 2 protrudes from the connector body 1 and is provided on the side and bottom of the connector body 1; the diverter structure 2 is recessed in the connector body 1 and is only provided on the side of the connector body 1; the diverter structure 2 is recessed in the connector body 1 and is only provided on the bottom of the connector body 1; the diverter structure 2 is recessed in the connector body 1 and is provided on the side and bottom of the connector body 1.

[0041] With the connector provided in the embodiment of the present application, the connector body 1 is set at an angle to the direction of gravity. Under the action of gravity, the oil on the connector flows along the surface of the connector to the connection between the connector body 1 and the diversion structure 2, and flows to the diversion structure 2, thereby dispersing the oil, extending the time for the oil to coagulate, and preventing the oil from gathering and dripping onto the stove. The user does not need to clean up the dripping oil, thereby improving the user experience.

[0042] Optionally, the flap connecting section 11 and the drive device connecting section 12 are integrally formed.

[0043] like Figure 1-2 As shown, as an optional embodiment, a rotation connection hole 13 for connecting to the flap is provided at one end of the flap connection section 11 away from the drive device connection section 12 .

[0044] Based on the previous embodiment, in this embodiment, the flap connecting section 11, at one end remote from the drive device connecting section 12, is movably connected to the range hood flap 3 to transmit a thrust or pull force to the flap 3 in the direction in which the flap 3 flips. The flap connecting section 11 is a plate-like structure, with its thickness extending vertically. A rotational connection hole 13 is defined along the thickness of the flap connecting section 11 at one end remote from the drive device connecting section 12. The flap 3 is provided with a connection hole that mates with the rotational connection hole 13. A rotation shaft passes through the rotational connection hole 13 and the connection hole to achieve rotational connection between the connector body 1 and the flap 3.

[0045] When the range hood is in use, the oil smoke generated by cooking flows toward the range hood under the suction of the range hood's fan. At this stage, the flap 3 is in an open state to form a smoke-collecting structure. Under the guidance of the flap 3, more smoke will flow on the smoke-collecting side of the flap 3. The smoke-collecting side of the flap 3 is the connection side of the flap 3 and the connector. The part of the connector close to the flap 3 is easily attached to the oil in the smoke and condensed, gathered and dripped. Therefore, the oil collection area 100 is close to the rotating connecting hole 13, and the diversion structure 2 is arranged in the oil collection area 100 to disperse the oil in places with more oil to avoid oil dripping.

[0046] like Figure 1-2 As shown, as an optional embodiment, a connecting through hole 14 for connecting to the driving device is provided at one end of the driving device connecting section 12 away from the flap connecting section 11 .

[0047] Based on the previous embodiment, in this embodiment, the drive device connection section 12 is a plate-like structure, with the thickness of the drive device connection section 12 arranged vertically. The first end of the flap connection section 11 is provided with the aforementioned rotation connection hole 13, and the second end of the flap connection section 11 is fixedly connected to the first end of the drive device connection section 12. The second end of the drive device connection section 12 is provided with a connection hole 14 along the thickness of the drive device connection section 12 for fixed connection to the drive device 4. The second end of the drive device connection section 12 is provided with three connection holes 14, distributed in a triangular pattern to increase the strength and stability of the connection between the drive devices 4. The first end of the flap connection section 11 is relatively far away from the second end of the drive device connection section 12.

[0048] like Figure 1-2 As shown, as an optional embodiment, the diversion structure 2 is arranged along the length direction of the flap connecting section 11.

[0049] Based on the above embodiments, in this embodiment, the diversion structure 2 is arranged in a straight line, the flap connecting section 11 is inclined in the direction of gravity, and the diversion structure 2 is also inclined in the direction of gravity. The flow direction of the oil in the diversion structure 2 is the same as the flow direction of the oil flap connecting section 11, which can effectively disperse the flowing oil and prevent the oil from gathering and dripping.

[0050] Optionally, the diversion structure 2 is provided at the bottom edge of the flap connecting section 11 to effectively disperse the oil accumulated at the bottom edge of the flap connecting section 11 .

[0051] like Figure 1-2 As shown, as an optional embodiment, a positioning hole 15 for connecting with the driving device is provided at one end of the driving device connecting section 12 away from the flap connecting section 11 .

[0052] Based on the above embodiment, in this embodiment, a positioning hole 15 is formed at the second end of the drive device connecting section 12 along the thickness direction of the drive device connecting section 12, and the positioning hole 5 is close to the above connection through hole 14. The positioning hole 5 is connected to the drive device by plugging, clamping, or bolting.

[0053] like Figure 1-2 As shown, in some embodiments, the diversion structure 2 includes a plurality of protrusions 34 that are dispersedly arranged, and the plurality of protrusions 34 protrude from the surface of the flap connecting section 11 .

[0054] Based on the previous embodiment, in this embodiment, the protrusions 34 can be any three-dimensional structure, such as a block or sphere. Each protrusion 34 of the diversion structure 2 has a maximum oil dispersion capacity, that is, each protrusion 34 has a maximum oil carrying capacity. If the maximum oil carrying capacity is exceeded, oil droplets will form. Therefore, to improve the oil dispersion capacity, multiple protrusions 34 are spaced apart to increase the area over which the oil is dispersed and prevent oil from agglomerating and dripping.

[0055] Optionally, the plurality of protrusions 34 are distributed in a sawtooth shape.

[0056] Optionally, the plurality of protrusions 34 are distributed in a wave shape.

[0057] like Figure 2 As shown, as an optional embodiment, the connector further includes a through-hole structure 5 , which passes through the connector body 1 .

[0058] Based on the foregoing embodiments, in this embodiment, the connector body 1 is a plate-like structure, and the through-hole structure 5 passes through the connector body 1. For example, the through-hole structure 5 is opened in the oil accumulation area 100 along the thickness direction of the connector body 1, and the opening of the through-hole structure 5 is located on the surface of the connector body 1. This can reduce the surface area of ​​the connector body 1 to reduce the contact area between the connector body 1 and the oil, that is, reduce the area of ​​oil adhesion, and can reduce the amount of oil in the flue gas adhered to the connector body 1, thereby reducing the amount of oil condensation and aggregation, to avoid oil aggregation and dripping.

[0059] like Figure 3-8 As shown, based on the same inventive concept, an embodiment of the present application provides a range hood, comprising a flap 3, a drive device 4, and a connecting piece of any one of the aforementioned embodiments of the present application; the connecting piece is connected to the flap 3 and the drive device 4, and the oil stains on the connecting piece flow to the diversion structure 2 when the flap 3 is opened.

[0060] Based on the previous embodiment, in this embodiment, the range hood is horizontally mounted. The two connecting ends of the connector are connected to the flap 3 and the drive device 4, respectively. The drive device 4 is used to provide the force that flips the flap 3, thereby driving the connector to push the flap 3 open or pull it closed. When the flap 3 is open, the horizontal direction is relatively flat. Under the action of gravity, the oil on the connector flows downward toward the diversion structure 2, thereby dispersing the oil.

[0061] In some embodiments, the driving device 4 includes a driving motor and a linkage structure connected to the driving motor. The linkage structure is further connected to a transmission member.

[0062] In the range hood provided in the embodiment of the present application, the oil stains on the connecting part flow along the surface of the connecting part to the connection between the connecting part body 1 and the diversion structure 2 under the action of gravity, and flow to the diversion structure 2, thereby dispersing the oil stains, thereby extending the time for the oil stains to coagulate, and preventing the oil stains from gathering and dripping onto the stove. The user does not need to clean up the dripping oil stains, thereby improving the user experience.

[0063] Based on the above-mentioned embodiment, in this embodiment, the range hood also includes an oil collection portion 31, which is arranged on the flap 3; an oil guide structure is provided between the connection between the flap 3 and the connecting piece and the oil collection portion 31; the oil on the connecting piece flows to the diversion structure 2 when the flap 3 is opened; the oil on the connecting piece flows through the connection between the flap 3 and the connecting piece, and the oil guide structure, to flow into the oil collection portion 31 when the flap 3 is closed.

[0064] The oil collection portion 31 has a space for accommodating oil, which is used to accommodate the oil on the connecting parts to prevent the oil on the dispersed structure of the connecting parts from dripping. After adjusting the closed and open states, the oil on the connecting parts, especially the oil on the dispersed structure, flows to the oil collection portion 31 and is stored in the oil collection portion 31, thereby realizing the transfer and concentration of oil.

[0065] The angles formed by the connecting part with the horizontal direction (or gravity direction) are different when the flap 3 is open and when the flap 3 is closed; when the flap 3 is closed, it is more inclined in the horizontal direction, that is, the angle formed with the horizontal direction is larger, and the oil on the connecting part flows along the connecting part to the connection between the flap 3 and the connecting part under the action of gravity. At this time, the flap 3 is also inclined in the horizontal direction. Under the action of gravity, the oil at the connection between the flap 3 and the connecting part flows along the oil guide structure into the oil collection part 31.

[0066] Optionally, the oil guide structure is the connection between the flap 3 and the connecting piece. In this case, the connection between the flap 3 and the connecting piece is relatively close.

[0067] like Figure 6-8 As shown, as an optional embodiment, the flap 3 includes an inner plate 32 and an outer plate 33 connected to each other; the inner plate 32 is provided with a protrusion 34 protruding in a direction away from the outer plate 33, and a gap is formed between the protrusion 34 and the outer plate 33. An opening connected to the gap is provided on the protrusion 34, and the opening is directed toward the connection between the flap 3 and the connector, and the oil collection portion 31 is the gap portion located below the opening.

[0068] Based on the previous embodiment, in this embodiment, the inner plate 32 and the outer plate 33 are fixedly connected. The protrusion 34 of the inner plate 32 is spaced apart from the outer plate 33, and the outer plate 33 and the protrusion 34 enclose an appropriate space. An oil collection section 31 is provided within this space, storing oil between the inner and outer plates 32, 33. An opening is defined on the sidewall of the protrusion 34, connecting the inner and outer plates 32, 33. This opening serves as the oil inlet for the oil collection section 31.

[0069] Optionally, the distance between the protrusion 34 and the outer plate 33 is greater than 0 mm and less than 3 mm, so that oil can flow between the inner plate 32 and the outer plate 33 .

[0070] Optionally, the outer plate 33 is a glass panel.

[0071] Optionally, the inner panel 32 is a glass panel.

[0072] Optionally, the outer plate 33 and the inner plate 32 are bonded together by hot melt adhesive.

[0073] like Figure 8 As shown, as an optional embodiment, the range hood further includes a connecting plate 6; one end of the connecting plate 6 is fixedly arranged on the back side of the outer plate 33, and the other end is penetrated by an opening and movably connected to the connecting member.

[0074] Based on the previous embodiment, in this embodiment, the connecting plate 6 includes a connecting plate body and a connecting protrusion protruding from the connecting plate body. The connecting plate body is sandwiched between the inner plate 32 and the outer plate 33. The connecting protrusion passes through the opening and extends out of the inner plate 32. The connecting protrusion is a sheet-like structure with the aforementioned connecting hole defined along its thickness for rotational connection with the connector.

[0075] Optionally, the plate surface of the connecting plate body is the aforementioned oil guide structure. In this case, the connection between the flap 3 and the connecting piece is far away from the oil collection portion 31.

[0076] In some embodiments, the range hood further includes a smoke hood 7 having a cavity inside, in which a driving device 4 is provided; a flap 3 is provided on the outside of the smoke hood 7; a connecting piece is passed through the smoke hood 7; the oil collection area 100 of the connecting piece extends out of the smoke hood 7 when the flap 3 is opened; and the oil collection area 100 of the connecting piece retracts into the cavity when the flap 3 is closed.
