Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0037] like Figure 1 As shown, this utility model embodiment provides a wiring structure for a range hood, including a connecting rod 1, a rotating plate 2, and a first lead wire fixing part 3. One end of the connecting rod 1 is hinged to the rotating plate 2, allowing the connecting rod 1 to move between a first position and a second position. The first lead wire fixing part 3 is located above the rotating plate 2. The connecting rod 1 has a wiring groove 11, and a second lead wire fixing part 4 is provided at one end of the wiring groove 11 near the rotating plate 2. The rotating plate 2 has a fixing ring 5. When the connecting rod 1 is in the first position, the distance between the first lead wire fixing part 3 and the second lead wire fixing part 4 is a first distance, and when the connecting rod 1 is in the second position, the distance between the first lead wire fixing part 3 and the second lead wire fixing part 4 is a second distance, and the first distance and the second distance are equal.

[0038] like Figures 2-5 As shown, in the range hood wiring structure provided in this embodiment of the present invention, the lead wire 8 passes through the wiring groove 11 inside the connecting rod 1, first connecting to the second lead wire fixing part 4 to position the lead wire 8, and then passing through the fixing ring 5 to connect to the first lead wire fixing part 3 above, repositioning the lead wire 8. Since the first distance between the first lead wire fixing part 3 and the second lead wire fixing part 4 when the connecting rod 1 is in the first position is equal to the second distance between the first lead wire fixing part 3 and the second lead wire fixing part 4 when the connecting rod 1 is in the second position, during wiring, it is only necessary to straighten and fix the lead wire 8 through the three points of the first lead wire fixing part 3, the second lead wire fixing part 4, and the fixing ring 5. The lead wire 8 will not be too long or too short, avoiding quality problems caused by improper lead wire length. Because no extra wire length needs to be reserved during wiring, the entire wiring is very neat, and there will be no excess wire movement causing quality problems such as wire clamping in the moving mechanism.

[0039] In one embodiment of this utility model, the first lead wire fixing part 3 and the second lead wire fixing part 4 can be perforated plates. The first lead wire fixing part 3 can be disposed at the top of the inner cavity of the smoke collection hood of the range hood.

[0040] like Figure 6 As shown, in one embodiment of this utility model, a first connecting plate 21 is provided on the side of the rotating plate 2, and the first connecting plate 21 is perpendicular to the rotating plate 2. A second connecting plate 22 is provided on the side of the first connecting plate 21 away from the rotating plate 2, and the second connecting plate 22 is perpendicular to the first connecting plate 21. The second connecting plate 22 is provided with a connecting hole 23, and the fixing ring 5 is disposed in the connecting hole 23. Further, the first connecting plate 21 is perpendicular to the plate surface of the rotating plate 2, and the first connecting plate 21 and the second connecting plate 22 are perpendicular to each other.

[0041] Because the retaining ring 5 may pull on the lead wire when the connecting rod 1 moves between the first and second positions, in order to prevent excessive force on the lead wire, such as Figure 7 As shown, in one embodiment of this utility model, the connecting hole 23 is an elongated hole, allowing the fixing ring 5 to move within the connecting hole 23 in the direction of the lead wire's movement, thus meeting the requirements of the wire length change throughout the entire movement. Additionally, as... Figures 8-9 As shown, in another embodiment of this utility model, the fixing ring 5 is an elastic ring, which can undergo elastic deformation and move with the lead wire due to its elasticity. Specifically, the fixing ring 5 is spiral in the circumferential direction, forming a spring-like shape. In another embodiment of this utility model, the fixing ring 5 is an elastic ring, and the connecting hole 23 is an elongated hole, with the extension direction of the elongated hole parallel to the first connecting plate 21.

[0042] like Figures 2-5 As shown, this utility model also provides a range hood, including a smoke collection hood 6, a flap 7, a lead wire 8, and the aforementioned range hood wiring structure. The rotating plate 2 is connected to the smoke collection hood 6, the end of the connecting rod 1 away from the rotating plate 2 is connected to the flap 7, the lead wire 8 is disposed in the wiring groove 11, the middle part of the lead wire 8 is connected to the second lead wire fixing part 4, and the end of the lead wire 8 is connected to the first lead wire fixing part 3 after passing through the fixing ring 5. By setting the wiring structure of this utility model in the range hood, during the manufacturing and installation process of the range hood, the installer can more easily determine how much wire needs to be reserved during the opening and closing of the flap 7 to avoid quality problems caused by excessive or insufficient wire length leading to wire accumulation or pulling, while also considering that users will not snag the wire during maintenance, thus avoiding safety hazards.

[0043] The flap 7 is equipped with electrical components, such as a switch display board and lamps. One end of the lead wire 8 is connected to the lead wire 8. The other end of the lead wire 8 passes through the wiring groove 11, passes through the second lead wire fixing part 4, the fixing ring 5, and the first lead wire fixing part 3 in sequence, and finally connects to the main control board inside the smoke hood 6.

[0044] In one embodiment of the present invention, the first lead wire fixing part 3 is provided at the top of the inner cavity of the smoke collection hood 6, and can be a plate with holes for the lead wire 8 to pass through the holes and be fixed.

[0045] like Figures 2-5 As shown, this utility model also provides a range hood, which differs from the aforementioned range hood in that the rotating plate 2 has a first connecting plate 21 on its side, and a second connecting plate 22 at its end. The second connecting plate 22 has a connecting hole 23, and the fixing ring 5 is disposed within the connecting hole 23. Figure 10As shown, when the connecting rod 1 is in the first position, the flap 7 is open, and the first connecting plate 21 is located outside the port of the wiring trough 11, blocking the port of the wiring trough 11. The user will not see the lead wire at the port of the wiring trough 11 from the smoke inlet of the smoke hood 6, and the user will not snag the lead wire during maintenance, thus avoiding safety hazards. Furthermore, as... Figure 11 As shown, when the connecting rod 1 is in the second position, the flap 7 is in the closed state, and the first connecting plate 21 is located between the lead wire 8 and the inner wall of the smoke hood 6. The first connecting plate 21 separates the lead wire 8 from the inner wall of the smoke hood 6 to prevent the lead wire 8 from rubbing against the housing of the smoke hood 6 and generating abnormal friction noise, and controls the lead wire 8 within the movement trajectory of the connecting rod 1.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
