These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0044] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0046] Unless otherwise stated, the term "multiple" means two or more.

[0047] As can be seen from the background technology, a lift-type range hood typically consists of a smoke collection hood 10, a main housing 20, and a lifting structure 30. The smoke collection hood 10 is equipped with a smoke inlet and is connected to the main housing 20. Under the action of the lifting structure 30, the smoke collection hood 10 can move up and down relative to the main housing 20 to adjust the height of the smoke inlet, so as to effectively capture cooking fumes in different cooking environments.

[0048] In existing lift-type range hood designs, in order to make full use of space and ensure structural stability, the lift structure 30 is usually installed directly inside the main box 20.

[0049] The movable end of the lifting structure 30 is connected to the smoke hood 10, as shown in the reference. Figure 3 As shown, the lifting structure 30 typically includes a drive component 31 and a push rod 32. The drive component 31 is located inside the main housing 20. The drive component 31 is connected to the push rod 32 and provides power for the movement of the push rod 32. The movable end of the push rod 32 is connected to the smoke hood 10, thereby realizing the up and down movement of the smoke hood 10 relative to the main housing 20.

[0050] However, it's conceivable that the fume hood 10 is connected to the main chamber 20. After absorbing the fumes, the fume hood 10 exhausts them outdoors through the exhaust vent on the main chamber 20. This means that during the range hood's exhaust process, the main chamber 20 is filled with fumes, causing the lifting structure 30 to be directly exposed to the fume environment. Oil molecules from the fumes adhere to the lifting structure 30, and a large amount of oil will slide off the lifting structure 30, dripping into the inside of the fume hood 10 or onto the stovetop through the exhaust vent, reducing the user experience.

[0051] To address the aforementioned problems, this application provides a smoke collection structure and a range hood. The smoke collection structure is used to collect oil stains from the lifting structure 30. The oil collection structure includes a housing 100, an oil-drawing component 200, and an oil-collecting device 300. The first end of the oil-drawing component 200 is used to receive oil stains from the lifting structure 30, and the second end of the oil-drawing component 200 abuts against the housing 100. The second end of the oil-drawing component 200 is located below the first end of the oil-drawing component 200. The oil-collecting device 300 is disposed below the oil-drawing component 200 and is used to at least receive oil stains from the housing 100. By setting up an oil-collecting component 200, oil sludge from the lifting structure 30 can be collected. The oil-collecting component 200 abuts against the housing 100, and the second end of the oil-collecting component 200 is located below the first end of the oil-collecting component 200. This allows the oil sludge on the lifting structure 30 to flow through the oil-collecting component 200 to the housing 100. An oil-collecting device 300 is set up below the housing 100 to collect the oil sludge on the housing 100. The oil sludge on the lifting structure 30 will flow through the oil-collecting component 200 and the housing 100 in sequence to the oil-collecting device 300, thereby realizing the diversion and collection of oil sludge on the lifting structure 30.

[0052] The smoke collection structure and range hood provided in this application can effectively prevent a large amount of oil stains from accumulating on the lifting structure 30, thereby preventing the oil stains on the lifting structure 30 from dripping directly onto the stove, and improving the user experience.

[0053] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0054] Combination Figures 1 to 5As shown, this application embodiment provides a smoke collection structure for collecting oil stains from a lifting structure 30. The smoke collection structure includes a housing 100, an oil-collecting component 200, and an oil collection device 300; the first end of the oil-collecting component 200 is used to receive the oil stains from the lifting structure 30, the second end of the oil-collecting component 200 abuts against the housing 100, and the second end of the oil-collecting component 200 is located below the first end of the oil-collecting component 200; this is equivalent to the oil-collecting component 200 being inclined.

[0055] An oil collecting device 300 is disposed below the oil inlet 200, and the oil collecting device 300 is at least used to collect oil slicks from the housing 100. In specific implementation, such as... Figure 4 and Figure 5 As shown, the first end of the oil-guiding component 200 can be connected to the outer wall of the driving component 31 of the lifting structure 30. In this case, the driving component 31 of the lifting structure 30 can be a motor. The specific structure of the driving component 31 is not limited in this embodiment. A large amount of oil will be attached to the outer wall of the driving component 31. The oil on the outer wall of the driving component 31 will flow onto the oil-guiding component 200. The second end of the oil-guiding component 200 abuts against the housing 100, thereby causing the oil on the inclined oil-guiding component 200 to flow onto the housing 100. The oil on the housing 100 will then flow downward along the housing 100 and into the oil collection device 300 below the housing 100.

[0056] Understandably, the housing 100 is the outer shell of the main box 20 or the smoke collection hood 10, and forms the overall outer contour of the range hood. The housing 100 has an internal mounting cavity for installing the lifting structure 30 and other components. The housing 100, which abuts against the second end of the oil-drawing component 200, is vertically arranged.

[0057] By setting up an oil-guiding component 200, oil stains from the lifting structure 30 can be collected. The oil-guiding component 200 abuts against the housing 100, and the second end of the oil-guiding component 200 is located below the first end of the oil-guiding component 200. This allows the oil stains on the lifting structure 30 to flow through the oil-guiding component 200 to the housing 100. An oil-collecting device 300 is set up below the housing 100 to collect the oil stains on the housing 100. The oil stains on the lifting structure 30 will flow through the oil-guiding component 200 and the housing 100 in sequence to the oil-collecting device 300, thereby realizing the guidance and collection of oil stains on the lifting structure 30. This effectively avoids the large accumulation of oil stains on the lifting structure 30, and thus prevents the oil stains on the lifting structure 30 from dripping directly onto the stovetop, improving the user experience.

[0058] In some embodiments, a smoke extraction fan 40 is provided inside the housing 100, and the air inlet of the smoke extraction fan 40 may face the front or rear side of the housing 100.

[0059] When the air inlet of the exhaust fan 40 faces the rear of the housing 100, the fumes can be drawn in through the rear side of the housing 100; when the air inlet of the exhaust fan 40 faces the front of the housing 100, the fumes can be drawn in through the front side of the housing 100. When the range hood is started, the exhaust fan 40 operates, creating a negative pressure at the smoke inlet to draw the fumes generated during cooking on the stove into the smoke collection hood 10, and then exhaust them from the air outlet of the exhaust fan 40.

[0060] In some embodiments, housing 100 includes a rear back panel 110 and a rear mounting beam 120.

[0061] The rear mounting beam 120 is located below the rear back plate 110 and has an oil outlet 1201 that communicates with the oil collection device 300. In a specific implementation, the second end of the oil guide 200 abuts against the rear back plate 110, which is vertically positioned. The rear mounting beam 120 is located below the rear back plate 110. As those skilled in the art can understand, the rear mounting beam 120 serves as a major structural component of the fume hood 10, forming the frame structure of the fume hood 10. Oil on the oil guide 200 first flows onto the rear back plate 110, and then onto the rear mounting beam 120. By providing the oil outlet 1201 on the rear mounting beam 120, the oil on the rear mounting beam 120 can flow into the oil collection device 300 through the oil outlet 1201.

[0062] The rear mounting beam 120 here not only serves as the frame structure of the fume hood 10, but also, through the oil outlet 1201, is used to receive oil stains on the back panel 110 and discharge the oil stains into the oil collection device 300. This allows the rear mounting beam 120 to guide and divert the flow of oil stains, which helps to improve the oil collection efficiency.

[0063] In some embodiments, refer to Figures 4 to 6 As shown, the rear-mounted beam 120 includes a support portion 121 and a connecting portion 122.

[0064] The connecting part 122 is located above the support part 121 and is connected to the rear back plate 110. The top of the support part 121 is provided with an oil inlet 1202 and the bottom of the support part 121 is provided with an oil outlet 1201.

[0065] In the above configuration, by providing the connecting part 122, the support part 121 can be easily connected to the back panel 110 through the connecting part 122, providing more connection points and improving the stability of the structure.

[0066] The connecting part 122 also allows oil stains on the back panel 110 to flow to the support part 121. The top of the support part 121 is provided with an oil inlet 1202. Specifically, the oil inlet 1202 is provided at the connection point between the connecting part 122 and the support part 121, facilitating the rapid flow of oil stains to the support part 121. The number of oil inlets 1202 is not limited. Oil stains on the support part 121 flow to the oil collection device 300 through the oil outlet 1201. By providing the oil outlet 1201, it is ensured that oil stains on the support part 121 are quickly discharged, preventing oil stains from accumulating on the support part 121 and optimizing the flow path of the oil stains.

[0067] In some embodiments, combined with Figure 2 , Figures 4 to 6 The housing 100 includes a rear cover 130, at least a portion of which is located outside the rear back panel 110.

[0068] The support portion 121 has a support protrusion that protrudes away from the rear cover 130 and is connected to the rear cover 130.

[0069] The oil inlet 1202 and the oil outlet 1201 are provided on the support protrusion; the side of the support protrusion facing the rear cover 130 is used for oil flow.

[0070] The rear cover 130 serves as an external protection and support component 121. Its outer position helps to better disperse and bear the force when subjected to external forces, reducing damage to the inside of the oil collection structure caused by external impacts, thereby maintaining the integrity and stability of the oil collection structure and extending its service life.

[0071] The support protrusion is positioned away from and connected to the rear cover 130, forming a stable support structure. This enhances the stability of the rear mounting beam 120, reduces the risk of structural deformation or damage due to excessive local stress, and further ensures the reliability and durability of the oil collection structure in complex working environments.

[0072] Furthermore, the side of the support protrusion facing the rear cover 130 is designed for oil flow, utilizing the shape and position of the support protrusion to guide the flow of oil. During the operation of the range hood, the support protrusion acts as a guide groove, accurately guiding the oil to the preset oil outlet 1201.

[0073] This guiding effect can prevent oil from flowing haphazardly, reduce the possibility of oil adhering to unnecessary parts, thereby reducing safety hazards caused by oil accumulation, and also help to keep the inside of the oil collection structure clean and improve its working efficiency.

[0074] In some embodiments, combined with Figures 2 to 7As shown, the system also includes a mounting plate 400, which is used to install the grille 50. Those skilled in the art will understand that the grille 50 is typically located at the smoke inlet and functions in the range hood to filter oil fumes and prevent debris from entering the range hood. By providing the mounting plate 400 and ensuring its compatibility with the oil collection structure, the grille 50 can be quickly and securely installed and replaced. This facilitates cleaning and maintenance by the user according to actual needs, ensuring the filtering effect of the grille 50 and maintaining the good performance of the range hood.

[0075] The mounting plate 400 is provided with an oil collecting part 410, which is connected to the rear cover 130. The mounting plate 400 is connected to the rear cover 130 through the oil collecting part 410, which improves the connection stability of the mounting plate 400. Of course, the mounting plate 400 also has a connection point to the smoke hood 10, such as the side of the mounting plate connecting to the inner wall of the smoke hood 10. Here, there are no restrictions on the connection structure of the mounting plate 400.

[0076] The oil collection section 410 is used to collect oil from the oil outlet 1201; the oil collection section 410 is provided with an oil collection port 411, which is connected to the oil collection device 300.

[0077] Oil stains on the rear mounting beam 120 flow through the oil outlet 1201 to the oil collection section 410. By setting an oil collection port 411 on the oil collection section 410, the oil stains on the oil collection section 410 can be concentrated and flow into the oil collection device 300 through the oil collection port 411. By setting the oil collection section 410, the oil stains flowing out of the oil outlet 1201 on the rear mounting beam 120 can be collected in a concentrated manner and collected into the oil collection device 300 through the oil collection port 411. This avoids the accumulation of oil stains on the oil collection section 410 or their flow everywhere, improves the efficiency and accuracy of oil stain collection, and reduces the impact of oil stains on other parts of the range hood.

[0078] In some embodiments, the oil collecting portion 410 has a connecting flange 420, which is disposed on the side of the support protrusion facing the rear cover 130, and the end of the connecting flange 420 away from the oil collecting portion 410 extends upward.

[0079] The connecting flange 420 provides a connection point between the oil collection section 410 and the rear cover 130. Furthermore, by having the end of the connecting flange 420 away from the oil collection section 410 extend upwards, it's understood that this upward-extending end forms a cavity between the connecting flange 420 and the support section 121, restricting oil splashing. When oil flows from the oil inlet 1202 onto the support section 121, it drips into this cavity. The connecting flange 420 prevents oil from flowing through the gap between the oil collection section 410 and the rear cover 130, thus improving the cleanliness of the range hood's interior and optimizing the oil flow path. Moreover, the connection point on the rear cover 130 with the connecting flange 420 is located between the connecting flange 420 and the support section 121, further enhancing the seal between the support section 121 and the connecting flange 420.

[0080] In some embodiments, refer to Figure 4 As shown, it also includes an oil guide box 500, which is used to collect oil stains from the smoke extraction fan 40.

[0081] The oil guide box 500 has an oil drain port 501, which is connected to the oil collection device 300.

[0082] In practice, the oil guide box 500 is connected to the bottom of the outer wall of the exhaust fan 40. Because the exhaust fan 40 is exposed to the oily fume environment, a large amount of oil will adhere to its outer wall. If the oil on the outer wall of the exhaust fan 40 is not cleaned in time, it will drip directly into the fume hood 10 or onto the stovetop through the smoke inlet. By setting up the oil guide box 500, the oil on the outer wall of the exhaust fan 40 flows downwards along the outer wall, and the oil that accumulates at the bottom of the outer wall of the exhaust fan 40 flows into the oil collection device 300 through the oil drain 501. This prevents the oil on the outer wall of the exhaust fan 40 from dripping, further improving the user experience.

[0083] In some embodiments, combined with Figure 8 As shown, in order to further optimize the flow path of oil from the oil guide box 500 to the oil collection device 300, a guide member 600 is provided below the oil outlet 501. The guide member 600 is used to receive the oil from the oil outlet 501. The guide member 600 is mounted on the mounting plate 400.

[0084] The guide component 600 is inclined toward the mounting plate 400 and abuts against the mounting plate 400, which is inclined toward the oil collecting device 300. Here, it can be understood that the first end of the guide member 600 abuts against the mounting plate 400, and the second end of the guide member 600 is higher than the first end. Oil flowing from the oil drain 501 flows through the second end of the guide member 600 to the position of the first end, and then flows onto the mounting plate 400. The first end of the mounting plate 400 abuts against the guide member 600, and the second end of the mounting plate 400 is connected to the mounting section. The first end of the mounting plate 400 is higher than the second end. With this arrangement, the oil on the mounting plate 400 flows through the inclined mounting plate 400 to the oil collection section 410. Thus, the oil collection section 410 can simultaneously collect oil from both the rear mounting beam 120 and the guide member 600, improving the utilization rate of the oil collection section 410. Furthermore, by setting two flow paths for oil inside the range hood, the oil collection efficiency can be further improved.

[0085] In practical implementation, at least one guide hole 601 is provided on the guide component 600, and the oil on the guide component 600 flows to the mounting plate 400 through the guide hole 601.

[0086] In some embodiments, the oil collecting part 410 is disposed on the rear side of the mounting plate 400; the oil collecting device 300 is configured as an oil receiving tray, which is located below the oil collecting part 410. The rear side of the mounting plate 400 is the second end of the mounting plate 400. Since the first end of the mounting plate 400 is higher than the second end, the oil on the mounting plate 400 can flow towards the oil collecting part 410 under its own gravity, optimizing the flow path of the oil and improving the oil collection efficiency. The oil receiving tray is something that those skilled in the art can conceive of. The main function of the oil receiving tray is to collect oil. The oil receiving tray is usually disposed below the fume hood 10 to facilitate user disassembly and cleaning. The specific structure of the oil receiving tray in the embodiments of this application is not limited.

[0087] The mounting plate 400 is provided with a mounting opening for mounting the grille 50, and an upward-facing oil-guiding flange 430 is provided around the periphery of the mounting opening. Here, the oil-guiding flange 430 extends upward, and it is understood that the oil-guiding flange 430 can prevent oil stains on the mounting plate 400 from spreading to the mounting opening, thereby preventing oil stains from contacting the grille 50 and preventing oil stains from dripping onto the stovetop through the grille 50.

[0088] This application embodiment also provides a range hood, including a range hood body and the aforementioned oil collection structure, wherein the oil collection structure has been described above and will not be repeated here. By setting the above-mentioned oil collection structure, the oil guiding path of the range hood can be optimized, the oil collection efficiency can be improved, oil stains can be prevented from dripping onto the stove, and the user experience can be improved.

[0089] The implementation principle of the oil collection structure and range hood provided in this application embodiment is as follows: The oil collection structure is used to collect oil stains from the lifting structure 30. The oil collection structure includes a housing 100, an oil-drawing component 200, and an oil collection device 300. The first end of the oil-drawing component 200 is used to receive oil stains from the lifting structure 30, and the second end of the oil-drawing component 200 abuts against the housing 100. The second end of the oil-drawing component 200 is located below the first end of the oil-drawing component 200. The oil collection device 300 is disposed below the oil-drawing component 200, and the oil collection device 300 is at least used to receive oil stains from the housing 100. By setting up an oil-guiding component 200, oil stains from the lifting structure 30 can be collected. The oil-guiding component 200 abuts against the housing 100, and the second end of the oil-guiding component 200 is located below the first end of the oil-guiding component 200. This allows the oil stains on the lifting structure 30 to flow through the oil-guiding component 200 to the housing 100. An oil-collecting device 300 is set up below the housing 100 to collect the oil stains on the housing 100. The oil stains on the lifting structure 30 will flow through the oil-guiding component 200 and the housing 100 in sequence to the oil-collecting device 300, thereby realizing the guidance and collection of oil stains on the lifting structure 30. This effectively avoids the large accumulation of oil stains on the lifting structure 30, and thus prevents the oil stains on the lifting structure 30 from dripping directly onto the stovetop, improving the user experience.
