[0055] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. 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

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] Unless otherwise stated, the term "multiple" means two or more.

[0061] As can be seen from the background technology, the range hoods in the relevant technology are equipped with a flap. When the range hood is turned on, the flap will automatically open to form an effective smoke collection area, which helps to fully absorb the oil fumes and steam generated during cooking. When the range hood is turned off, the flap will retract and be attached to the surface of the smoke collection hood to ensure the overall aesthetics of the kitchen and the rational use of space.

[0062] The wiring harnesses of electrical components installed on the flap often need to pass through the gap between the flap and the smoke hood to run from the flap to the smoke hood and then connect to the power box on top of the smoke machine. However, when the wiring harness between the flap and the smoke hood is not properly fixed, the swaying wiring harness can easily cross or interfere with the movement path of the flap.

[0063] For example, when the flap moves, it may cause compression, pulling, or friction on the wire harness, leading to tangling or damage. Alternatively, the wire harness may lie directly across the rotating shaft of the flap, and as the flap rotates, the wire harness may be caught in the rotating shaft, resulting in tangling and pulling.

[0064] If the wiring harness becomes tangled or pulled, it may affect its normal power transmission or signal transmission, which may cause some functions of the range hood to malfunction. In severe cases, it may even damage the wiring harness and affect the overall service life of the range hood.

[0065] To address the aforementioned issues, this application provides a flip-type smoke hood, which includes a smoke collection hood and a flip-type structure. The flip-type structure is movably connected to the smoke collection hood and can rotate relative to the smoke collection hood around a rotation axis. A gap is formed between the flip-type structure and the smoke collection hood along the rotation axis.

[0066] The flip-type smoke hood also includes a wiring harness and a wiring structure. The wiring structure is set in the gap and has a first connecting port and a second connecting port. The first connecting port is close to the flip-type structure and is coaxial with the rotation axis; the second connecting port is close to the smoke collection hood; at least a portion of the wiring harness is located within the wiring structure.

[0067] By setting a first connection port coaxial with the rotation axis of the flip structure in the wiring structure, the first end of the wire harness can be connected to the flip structure through the first connection port. The wire harness can maintain a relatively stable position when the flip structure rotates, reducing the possibility of tangling and pulling, thereby reducing the movement and wear of the wire harness.

[0068] By setting a second connection port near the smoke hood in the wiring structure, the second end of the wire harness can be connected to the smoke hood through the second connection port, which can ensure that the wire harness can be smoothly connected to the electrical system inside the smoke hood.

[0069] Specifically, the flip-type smoke hood provided in this application embodiment can limit and protect the wire harness located between the flip plate and the smoke collection hood through the wiring structure, ensuring its stable position when the flip plate structure rotates, and reducing the influence of the external environment on the wire harness. This allows the wire harness to stably connect the electrical components of the flip plate structure and the smoke collection hood, ensuring the normal transmission of power and signals, and guaranteeing the normal function and service life of the smoke hood.

[0070] 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.

[0071] Combination Figure 1 and Figure 2 As shown in the figure, this application provides a flip-type range hood, including a smoke collection hood 100. The smoke collection hood 100 is used to form a smoke collection chamber, which is typically provided with a smoke inlet (not shown in the figure) facing the cooking area.

[0072] The flip-type range hood also includes a main housing 600, which is located above the smoke collection hood 100. The main housing 600 is used to install a smoke extraction fan (not shown in the figure). The air inlet of the smoke extraction fan is connected to the smoke collection chamber, and the air outlet of the smoke extraction fan can be connected to the exhaust duct.

[0073] The fumes generated in the cooking area can be drawn into the smoke collection chamber through the smoke inlet by the smoke extraction fan, and finally discharged through the exhaust duct.

[0074] It should be noted that flip-type range hoods typically have oppositely arranged front and rear sides, oppositely arranged left and right sides, and oppositely arranged top and bottom sides.

[0075] The front side of the flip-type range hood (facing the center X direction) is for the user and has a control panel for operation. The rear side of the flip-type range hood (facing away from the center X direction) can be used to connect to the surface to which the flip-type range hood will be installed.

[0076] Taking the user's perspective facing the front of the flip-type range hood as an example, the left side of the flip-type range hood (facing away from the front) Figure 1 The side facing the Y direction) is closer to the user's left, and the right side of the flip-type range hood (facing) Figure 1 (The side facing the Y direction) is closer to the user's right side.

[0077] The top of the flip-type range hood (facing) Figure 1 The side facing Z (in the middle) can also be used to connect with the installation surface of the flip-type range hood. The smoke inlet can be located at the bottom of the flip-type range hood (facing away from the wall). Figure 1 (On one side of the Z-axis) to capture the fumes produced by the cooking area below.

[0078] The flip-type range hood also includes a flip-type structure 200. The flip-type structure 200 is typically movably connected to the bottom front side of the smoke collection hood 100, and the flip-type structure 200 can rotate relative to the smoke collection hood 100 about the rotation axis 90.

[0079] Combination Figure 1As shown, when the flip-plate range hood is running, the flip-plate structure 200 can be flipped to the front of the range hood to unfold and fully open the smoke inlet.

[0080] Combination Figure 2 As shown, when the flap-type range hood is not in operation, the flap structure 200 can flip to the rear of the range hood to close, sealing the smoke inlet. When closed, the flap structure 200 is flush with the bottom of the smoke collection hood 100, achieving a neat and aesthetically pleasing effect.

[0081] Combination Figure 3 As shown, the flip-type smoke hood also includes a wiring harness 300 (not shown in the figure) and a wiring structure 400. Along the rotation axis 90 of the flip-type structure 200, a gap 500 is formed between the flip-type structure 200 and the smoke collection hood 100; the existence of the gap 500 provides space for the wiring structure 400 to be installed. The wiring structure 400 is disposed within the gap 500 to limit and protect the wiring harness 300 located between the flip-type structure 200 and the smoke collection hood 100.

[0082] Understandably, the wiring structure 400 is set within the gap 500 to utilize the existing space and provide a dedicated channel to accommodate the wire harness 300, limit the range of movement of the wire harness 300, and protect the wire harness 300 from the influence of the external environment, preventing it from getting tangled and excessively stretched when the flip structure 200 rotates.

[0083] Combination Figure 4 and Figure 5 As shown, in some embodiments, the wiring structure 400 has a first connection port 4011 and a second connection port 4021. The first connection port 4011 is close to the flap structure 200 and is coaxially arranged with the rotation axis 90. The second connection port 4021 is close to the smoke hood 100. At least a portion of the wire harness 300 is located inside the wiring structure 400. The first end of the wire harness 300 is connected to the flap structure 200 through the first connection port 4011, and the second end of the wire harness 300 is connected to the smoke hood 100 through the second connection port 4021.

[0084] The first connecting port 4011 is close to the flap structure 200 and is coaxially set with the rotation axis 90. The movement of the wire harness 300 located at the first connecting port 4011 is restricted to a fixed path when the flap structure 200 rotates. The wire harness 300 has high stability and reliability, which can reduce the stress and wear on the wire harness 300 during rotation and reduce the possibility of entanglement and pulling.

[0085] The second connection port 4021 is located directly close to the smoke hood 100, which ensures that the wiring harness 300 can be easily connected to the electrical components of the smoke hood 100, reducing the complexity of the wiring harness 300 layout.

[0086] By placing a portion of the wire harness 300 within the wiring structure 400, and connecting the first end of the wire harness 300 to the flap structure 200 through the first connecting port 4011, and the second end of the wire harness 300 to the smoke hood 100 through the second connecting port 4021, the portion of the wire harness 300 located within the wiring structure 400 can be protected from the influence of the external environment, ensuring stability when the flap structure 200 rotates, and helping to extend the service life of the wire harness 300.

[0087] Specifically, the flip-type range hood provided in this application embodiment protects and guides the wiring harness 300 located between the flip structure 200 and the smoke collection hood 100 through the wiring structure 400. This ensures that the wiring harness 300 maintains a relatively stable position when the flip structure 200 rotates, reducing the possibility of tangling and pulling. It also reduces the impact of the external environment on the wiring harness 300, enabling the wiring harness 300 to stably connect the electrical components of the flip structure 200 and the smoke collection hood 100. This effectively solves the problem of the wiring harness 300 being easily tangled and pulled when the flip structure 200 rotates, ensuring the normal function and service life of the range hood.

[0088] In some embodiments, the wiring structure 400 includes a first part 401 and a second part 402 connected to each other; the first part 401 has an angle between its extension direction and the rotation axis 90, and a first connection port 4011 is disposed on the side of the first part 401 near the flap structure 200; the extension direction of the second part 402 is parallel to the rotation axis 90, and a second connection port 4021 is disposed at the end of the second part 402 near the smoke hood 100.

[0089] By dividing the wiring structure 400 into two parts, the spatial layout between the flap structure 200 and the smoke hood 100 can be adapted more flexibly, the arrangement path of the wire harness 300 can be optimized, and the wire harness 300 can be provided with more effective protection and guidance.

[0090] Specifically, the extension direction of the first part 401 forms an angle with the rotation axis 90, which can improve the path of the wire harness 300. The first connecting port 4011 is located in the first part 401 near the flap structure 200. Then, the wire harness 300 located inside the first part 401 can be directly connected to the electrical components inside the flap structure 200 after passing through the first connecting port 4011. This reduces the complexity of the layout path and also reduces the bending and detour of the wire harness 300 between the first part 401 and the flap structure 200.

[0091] Furthermore, during the rotation of the flap 230, the position of the first connecting port 4011 in the first part 401 always corresponds to the rotation axis of the flap 230. Thus, the wire harness 300 that passes through the first connecting port 4011 and enters the flap structure 200 can have a small displacement. These wire harnesses 300 can adapt to the rotation of the flap structure 200, reducing the bending and pulling of the wire harnesses 300.

[0092] The extension direction of the second part 402 is parallel to the rotation axis 90, and the second connecting port 4021 is located in the second part 402 near the smoke hood 100. Then the wire harness 300 passing through the smoke hood 100 can be directly laid in the second part 402, reducing the bending and detour of the wire harness 300 between the second part 402 and the smoke hood 100, and reducing the complexity of the layout path.

[0093] The portion of the wire harness 300 located inside the second part 402 can be parallel to the rotation axis 90, which can reduce the length requirement of the wire harness 300 and reduce the complexity and potential wear risk of the wire harness 300 during the connection process.

[0094] In some embodiments, the second part 402 is connected to the rear side of the first part 401, and the second part 402 is located behind the rotation axis 90; the flap structure 200 is provided with a rotating seat 210, and the flap structure 200 is rotatably connected to the smoke hood 100 through the rotating seat 210, and the rotating seat 210 is located in front of the second part 402.

[0095] Understandably, side plates 110 can be provided on both sides of the smoke hood 100 in the width direction; rotating seats 210 are provided at both ends of the flip structure 200 in the width direction. The rotating seats 210 are fixed to the inner side of the side plates 110 of the smoke hood 100. The rotating seats 210 are provided with a rotating shaft. The flip structure 200 rotates relative to the smoke hood 100 through the rotating shaft.

[0096] Among them, the axes of rotation on the two rotating seats 210 are located on the same straight line, which is the rotation axis 90 of the flap structure 200.

[0097] It is also understandable that, due to the presence of the rotating seat 210 at both ends of the rotation axis 90, the inlet and outlet of the wiring harness 300 on the flap structure 200 and the inlet and outlet of the wiring harness 300 on the smoke hood 100 cannot be completely coaxially aligned with the rotation axis 90. In other words, the position of the inlet and outlet is spatially deviated from the rotation axis 90.

[0098] Due to the deviation between the inlet / outlet and the rotation axis 90, the wiring harness 300 cannot be arranged along a straight path of the rotation axis 90 between the flap structure 200 and the smoke hood 100. Therefore, the wiring harness 300 cannot be kept on a fixed straight line when the flap structure 200 rotates, but may be pulled or bent.

[0099] When the flap structure 200 rotates, the wire harness 300 may become tangled or stretched because it cannot maintain a straight line. This causes the wire harness 300 to be subjected to additional stress during movement, increasing the risk of wear and causing instability in power transmission or signal transmission.

[0100] By placing the second part 402 behind the rotating seat 210 and the first part 401, and positioning it entirely behind the rotation axis 90, the second part 402 can spatially avoid the rotation axis 90, creating a path for the wire harness 300 between the flap structure 200 and the smoke hood 100. This minimizes bending and pulling caused by the deviation of the wire harness 300 from the rotation axis 90, and also avoids interference between the second part 402 and the rotating seat 21 in terms of their arrangement.

[0101] Along the rotation axis 90, the first portion 401 is positioned away from the rotating seat 210 relative to the second portion 402. Thus, the first portion 401 is spatially closer to the periphery of the flap structure 200, which helps to provide a more direct path for the wiring harness 300 to connect to the electrical components of the flap structure 200.

[0102] The end of the first part 401 furthest from the second part 402 extends to the axis of rotation 90. This arrangement reduces bending and winding of the wiring harness 300, allowing it to be connected more directly to the electrical components of the flap structure 200. This arrangement also helps maintain the stability of the wiring harness 300 when the flap structure 200 rotates.

[0103] The arrangement of the first part 401 and the second part 402 can effectively guide the wiring harness 300 from the smoke hood 100 to the flap structure 200. Specifically, when the wiring harness 300, which passes through the smoke hood 100, is arranged from the second part 402 to the first part 401, the arrangement direction of the wiring harness 300 can be changed, that is, from a position deviating from the rotation axis 90 to a position coinciding with the rotation axis 90, and finally reaching the flap structure 200 from the first connecting port 4011.

[0104] The portion of the wire harness 300 that passes through the first connecting port 4011 and enters the flap structure 200 has its position coincided with the rotation axis 90, which can maintain the stability of its position when the flap structure 200 rotates, reducing the possibility of entanglement and pulling.

[0105] Combination Figure 6 and Figure 7As shown, in some embodiments, the flap structure 200 includes a control housing 220, the control housing 220 is provided with a first inlet and outlet 221, the first inlet and outlet 221 and the first connecting port 4011 are spaced apart along the rotation axis 90; the first end of the wire harness 300 is disposed on the flap structure 200 through the first connecting port 4011 and the first inlet and outlet 221 in sequence.

[0106] Specifically, a gap 500 can be formed between the control housing 220 and the side plate 110 of the smoke hood 100, and the wiring structure 400 is located between the control housing 220 and the side plate 110 of the smoke hood 100.

[0107] Understandably, the control housing 220 provides dedicated space for housing and protecting the wiring harness 300, while the first inlet / outlet 221 provides a path for the wiring harness 300 to enter the flap structure 200.

[0108] The first inlet / outlet 221 and the first connecting port 4011 are spaced apart along the rotation axis 90, which can ensure that the wire harness 300 has a reasonable path when it enters the flip structure 200 from the wiring structure 400. The wire harness 300 can be connected to the electrical components of the flip structure 200 with the shortest path, reducing the bending of the wire harness 300 during rotation.

[0109] The smoke hood 100 is provided with a second inlet and outlet 111, which is connected to the second connecting port 4021; the second end of the wire harness 300 is provided in the smoke hood 100 through the second inlet and outlet 111 and the second connecting port 4021.

[0110] The second inlet / outlet 111 provides a path for the wire harness 300 to enter the smoke hood 100. By setting the second inlet / outlet 111 and connecting it with the second connecting port 4021, it can be ensured that the wire harness 300 can easily enter the smoke hood 100, reducing the complexity of the wire harness 300 arrangement.

[0111] Combination Figure 8 and Figure 9 As shown, in some embodiments, the wiring structure 400 includes a base 410 and a cover plate 420; the base 410 is connected to the smoke hood 100, and an opening 411 is provided on one side of the base 410 for inserting the wire harness 300; the cover plate 420 is detachably disposed on the base 410 to close or open the opening 411.

[0112] The wiring structure 400 consists of a base 410 and a cover plate 420. The base 410 and the cover plate 420 can form a closed channel to ensure that the wiring harness 300 is not disturbed by external factors during use.

[0113] By fixing the base 410 to the smoke hood 100, the wiring structure 400 can be kept stable during the operation of the smoke machine, avoiding loosening or displacement caused by vibration or other factors.

[0114] The base 410 has an opening 411 on one side, which provides a convenient entry point for placing and adjusting the wire harness 300, ensuring that the wire harness 300 can be smoothly placed inside the wiring structure 400.

[0115] The design of the removable cover plate 420 facilitates the installation and maintenance of the wire harness 300.

[0116] Combination Figures 6 to 9 As shown, in some embodiments, the opening 411 is arranged facing the rear; the first end of the cover plate 420 and the base 410 form a first communication port 4011, and the second end of the cover plate 420 and the base 410 form a second communication port 4021.

[0117] Understandably, the opening 411 on the base 410 is set towards the rear of the flip-type range hood. This reduces the possibility of the wiring harness 300 being exposed in front, allowing the wiring harness 300 to be more concealed during installation and layout, reducing the direct impact of the external environment on the wiring harness 300, and improving the protection effect of the wiring harness 300.

[0118] After the cover plate 420 is installed, its first end is a certain distance away from the end of the opening 411, so that the first end of the cover plate 420 and the base 410 can form a first connecting port 4011. The wire harness 300 can smoothly enter the flap structure 200 through the first connecting port 4011, providing a stable power and signal connection.

[0119] The second end of the cover plate 420 can be connected with the end of the base 410 to form a second communication port 4021, so that the wire harness 300 can smoothly enter the smoke hood 100 through the second communication port 4021, providing a stable power and signal connection.

[0120] Combination Figure 8 and Figure 9 As shown, in some embodiments, a first snap-fit ​​member 421 is provided on the cover plate 420. The first snap-fit ​​member 421 can be provided near the first end of the cover plate 420 and is inserted into the opening 411. The first snap-fit ​​member 421 has a snap-fit ​​connector 4211, which abuts against the inner surface of the base 410.

[0121] Specifically, limiting protrusions 414 can be provided on both sides of the opening 411 in the width direction. The limiting protrusions 414 are located on the first part 401 of the wiring structure 400. The limiting protrusions 414 extend into the opening 411, and the snap connector 4211 can abut against the inner surface of the limiting protrusions 414.

[0122] During installation, the first snap-fit ​​member 421 of the cover plate 420 is inserted into the opening 411 and slid towards one end of the opening 411 where a limiting protrusion 414 is provided. When the first snap-fit ​​member 421 moves to a position corresponding to the limiting protrusion 414, the snap-fit ​​connector 4211 of the first snap-fit ​​member 421 can abut against the inner surface of the limiting protrusion 414, preventing the first end of the first snap-fit ​​member 421 from coming out of the opening 411, thus realizing the connection between the cover plate 420 and the base 410.

[0123] Combination Figure 8 and Figure 9 As shown, in some embodiments, a second snap-fit ​​member 422 is provided on the cover plate 420. The second snap-fit ​​member 422 can be provided near the second end of the cover plate 420, and the base 410 is provided with an abutment member 412. The abutment member 412 can be located in the second part 402 of the wiring structure 400, and the abutment member 412 can extend into the opening 411. The second snap-fit ​​member 422 is inserted into the opening 411, and the abutment member 412 abuts against the second snap-fit ​​member 422.

[0124] During installation, the second snap-fit ​​member 422 of the cover plate 420 is inserted into the position corresponding to the abutment member 412 in the opening 411, allowing the second snap-fit ​​member 422 to abut against the abutment member 412, thereby further connecting the cover plate 420 and the base 410. The second snap-fit ​​member 422 and the first snap-fit ​​member 421 together provide a fixing effect, making the connection between the cover plate 420 and the base 410 stable.

[0125] Understandably, the connection between the first snap-fit ​​421 and the limiting protrusion 414, as well as the connection between the second snap-fit ​​422 and the abutment 412, adopts a relatively simple connection method, which facilitates the assembly and disassembly of the cover plate 420 and the base 410, and provides convenience for the laying and maintenance of the wiring harness 300.

[0126] Combination Figure 10 As shown, in some embodiments, the second snap-fit ​​member 422 includes a fixed portion 4221 and an elastic portion 4222 connected to each other; the elastic portion 4222 can extend or retract towards or away from the fixed portion 4221, and both the fixed portion 4221 and the elastic portion 4222 are inserted into the opening 411, and the abutting member 412 abuts against the surface of the elastic portion 4222 away from the fixed portion 4221.

[0127] One end of the fixing part 4221 is connected to the cover plate 420, and the other end of the fixing part 4221 is connected to the elastic part 4222. The elastic part 4222 and the fixing part 4221 can be arranged in parallel, and the elastic part 4222 and the fixing part 4221 can be distributed at intervals along the width direction of the opening 411.

[0128] The abutment 412 is disposed on a first side in the width direction of the opening 411 and extends to a second side in the width direction of the opening 411. The initial widths of the elastic part 4222 and the fixing part 4221 are greater than the distance between the abutment 412 and the second side in the width direction of the opening 411.

[0129] During installation, by squeezing the elastic part 4222, the elastic part 4222 can be contracted near the fixed part 4221 to reduce the width of the elastic part 4222 and the fixed part 4221, so that the second snap-fit ​​member 422 can enter the opening 411 from the position of the abutment member 412; when the elastic part 4222 is released, the elastic part 4222 recovers, so that the elastic part 4222 and the fixed part 4221 have a tendency to recover their initial width. Then the elastic part 4222 can abut against the surface of the abutment member 412 on the second side in the width direction of the opening 411, forming a stable support, so that the second snap-fit ​​member 422 is stably connected in the opening 411.

[0130] In some embodiments, an operating part 4223 may be provided at one end of the elastic part 4222 that is away from the fixed part 4221. The extending direction of the operating part 4223 is perpendicular to the extending direction of the elastic part 4222. The operating part 4223 can provide a convenient operating point to realize the extension and retraction of the elastic part 4222.

[0131] After the elastic part 4222 abuts against the abutting member 412, the operating part 4223 can also abut against the side of the abutting member 412 away from the interior of the base 410, providing additional fixation for the connection between the cover plate 420 and the base 410, preventing the cover plate 420 from being overly embedded inside the base 410, and ensuring the stability of the cover plate 420 in closing the opening 411.

[0132] Combination Figure 6 and Figure 9 As shown, in some embodiments, the wiring structure 400 is further provided with a third snap-fit ​​member 413, which is inserted into the second inlet / outlet 111. The third snap-fit ​​member 413 has a hook 4131, which abuts against the inner wall of the smoke hood 100.

[0133] Understandably, the wiring structure 400 is directly connected to the second inlet / outlet 111 of the smoke hood 100 via the third connector 413, which allows the second connection port 4021 to correspond better with the second inlet / outlet 111, reducing the bending and detour of the wire harness 300 between the smoke hood 100 and the wiring structure 400, and reducing the complexity of the wiring harness 300's routing path.

[0134] Furthermore, the aforementioned snap-fit ​​structure is easy to install, and the snap hook 4131 contacts the inner wall of the smoke hood 100, providing stable support and fixing force, which can ensure the stability of the wiring structure 400 at the second inlet / outlet 111, and enhance the limiting and protection effect on the wire harness 300.

[0135] In summary, the flip-type smoke hood provided in this application embodiment has a first connecting port 4011 on the wiring structure 400, coaxial with the rotation axis 90 of the flip-type structure 200. The first end of the wire harness 300 is connected to the flip-type structure 200 through the first connecting port 4011. This allows the wire harness 300 to maintain a relatively stable position when the flip-type structure 200 rotates, reducing the possibility of tangling and pulling, thereby reducing the movement and wear of the wire harness 300. A second connecting port 4021 is provided on the wiring structure 400 near the smoke hood 100. The second end of the wire harness 300 is connected to the smoke hood 100 through the second connecting port 4021. This reduces the bending and detours of the wire harness 300 between the smoke hood 100 and the wiring structure 400, reducing the complexity of the wire harness 300's layout path.
