Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solutions disclosed in this invention, the technical solutions in the disclosed embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention disclosed herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0039] In existing technologies, the hinges used to connect and fix the main structure of the range hood to the smoke baffle assembly do not have a pre-positioning structure. When the smoke baffle is assembled on the production line, because the smoke baffle has a certain weight and the contact surface with the hinge is small, it cannot be fixed by itself. Workers need to support the smoke baffle assembly with one hand to prevent it from flipping over, while aligning the smoke baffle assembly with the hinge on the main structure of the range hood, and assemble it with the other hand. In this case, it is difficult to effectively fix the smoke baffle assembly, and it is also difficult to align the mounting holes of the smoke baffle assembly and the hinge, which is prone to deviation. If the assembly and locking are forced under the condition of hole deviation, the mounting holes may be damaged, resulting in defective products. Not only is the assembly effect poor and the defect rate high, but it also affects the production efficiency.

[0040] In order to effectively fix the smoke baffle assembly, prevent the smoke baffle assembly from flipping and falling off during assembly, and improve assembly efficiency and effect while reducing the defect rate, this application provides a fixing structure for the smoke baffle assembly.

[0041] The following is in conjunction with the appendix Figure 1-13 The technical solutions in the embodiments of this application are introduced.

Positioning protrusions 112 and 122 and at least two limiting flanges 111 and 121 are located at the target end, and at least two limiting flanges 111 and 121 are located on the side of the positioning protrusions 112 and 122. Bracket flanges 511 and 521 are located in the area formed between the at least two limiting flanges 111 and 121. The at least two limiting flanges 111 and 121 are used to limit the bracket flanges 511 and 521.

[0044] Specifically, the connection between the rotating component 1 and the fixed bracket 2 constitutes the rotation center of the rotating component 1; the positioning protrusions 112, 122 and at least two limiting flanges 111, 121 are determined according to the shape of the bracket flanges 511, 521.

[0045] Optionally, if two limiting flanges 111 and 121 are provided on the rotating member 1, the target end includes a target edge and a side edge located on the side of the target edge; the positioning protrusions 112 and 122 are located on the target edge, and the two limiting flanges 111 and 121 are respectively located on the side edge of the target edge.

The limiting flanges 111 and 121 on the rotating part 1 contact the side of the bracket flanges 511 and 521 away from the smoke baffle 53. The length of the limiting flanges 111 and 121 on the side of the target side is related to the length of the bracket flanges 511 and 521 between the side of the bracket flanges 511 and 521. The length of the limiting flanges 111 and 121 on the rotating part 1 is related to the length of the bracket flanges 511 and 521 in the direction perpendicular to the smoke baffle 53.

[0049] In an optional embodiment, one end of the rotating member 1 is provided with a first opening 113, 123, and the bracket flanges 511, 521 are provided with a second opening 513, 523.

The fasteners include, but are not limited to, screws. Correspondingly, the inner walls of the first openings 113 and 123 and the second openings 513 and 523 are provided with threads.

[0051] In an optional embodiment, the fixed bracket 2 includes a first connecting flange 214, 221 and a second connecting flange 215, 222. The rotating member 1 is rotatably connected to the fixed bracket 2 via pins 81, 82, with the two ends of the pins 81, 82 passing through the first connecting flange 214, 221 and the second connecting flange 215, 222, respectively.

[0052] Specifically, the fixed bracket 2 has a first connecting flange 214 and a second connecting flange 215, as well as a first connecting flange 221 and a second connecting flange 222, on the end connected to the rotating member 1. The first connecting flange 214 and the second connecting flange 215 are correspondingly arranged, and the first connecting flange 221 and the second connecting flange 222 are correspondingly arranged. The rotating member 1 is located between the first connecting flange 214 and the second connecting flange 215, and between the first connecting flange 221 and the second connecting flange 222. The pins 81 and 82 pass through the first connecting flange 214, the rotating member 1, the second connecting flange 215, the first connecting flange 221, the rotating member 1, and the second connecting flange 222, respectively, so that the rotating member 1 is rotatably connected to the fixed bracket 2 and rotates around the pins 81 and 82, thereby forming a double-sided fixed support structure for the rotating member 1.

[0053] Optionally, the bracket flanges 511 and 521 are arranged perpendicular to the smoke baffle 53, and the side of the bracket flanges 511 and 521 away from the smoke baffle 53 is provided with a guide chamfer. In this way, the bracket flanges 511 and 521 can be smoothly inserted into the area formed by at least two limiting flanges 111 and 121, which plays a guiding role.

[0054] In some embodiments, such as Figure 3-5 As shown, the smoke baffle brackets 51 and 52 include a first smoke baffle bracket 51, which includes a first bracket flange 511. The fixed bracket 2 includes a first fixed bracket 21. The rotating member 1 includes a first rotating member 11, one end of which is fixedly connected to the first bracket flange 511, and the other end of which is rotatably connected to the first fixed bracket 21. The first rotating member 11 is provided with a first positioning protrusion 112 and at least two first limiting flanges 111. Two first limiting flanges 111 are located at the first target end, and at least two first limiting flanges 111 are located on the side of the first positioning protrusion 112. The first bracket flange 511 is located in the area formed between the at least two first limiting flanges 111. The at least two first limiting flanges 111 are used to limit the first bracket flange 511. The first positioning protrusion 112 is used to align the first rotating member 11 with the first bracket flange 511. The first target end is the end where the first rotating member 11 is fixed to the first bracket flange 511.

The first fixed bracket 21 is fixed to the front end inside the range hood housing 7 through the first fixed edge 213. The other end of the first rotating member 11 is rotatably connected to the first fixed edge 213. The connection between the first rotating member 11 and the first fixed edge 213 constitutes the rotation center of the first rotating member 11. The limiting flange 216 and the first front side folded edge 212 are located on the same side of the first bracket body 211. The limiting flange 216 can be used to limit the rotation position of the second rotating member 4 and limit its maximum opening position (corresponding to the opening limit position of the smoke baffle 53).

[0056] Specifically, the first smoke baffle bracket 51 is fixed to the side of the smoke baffle 53 facing the inside of the range hood housing 7.

The first limiting folded edge 111 on the side of the first target edge contacts the side of the first bracket folded edge 511. The first limiting folded edge 111 on the surface of the first rotating member 11 contacts the side of the first bracket folded edge 511 away from the smoke baffle 53. The specific setting of the first limiting folded edge 111 on the side of the first target edge is related to the length between the sides of the first bracket folded edge 511. The specific setting of the first limiting folded edge 111 on the surface of the first rotating member 11 is related to the length of the first bracket folded edge 511 in the direction perpendicular to the smoke baffle 53.

[0062] In an optional embodiment, one end of the first rotating member 11 is provided with a first opening 113, and the first bracket folded edge 511 is provided with a corresponding second opening 513. One end of the first rotating member 11 is fixedly connected to the second opening 513 of the first bracket folded edge 511 through the first opening 113. The first positioning protrusion 112 is also used to align the first opening 113 of the first rotating member 11 and the second opening 513 of the first bracket folded edge 511 near the first target end.

One end of the first rotating member 11 is provided with at least two first openings 113, and the first bracket flange 511 is provided with at least two second openings 513. The first openings 113 and the second openings 513 are correspondingly arranged. One end of the first rotating member 11 passes through the first openings 113 and the second openings 513 through fasteners, thereby fixing it to the first bracket flange 511. In this way, one side of the smoke baffle assembly 5 is locked. Optionally, the first openings 113 and the second openings 513 can be openings of shapes such as circular openings, elliptical openings, square openings, or polygonal openings. The fasteners include, but are not limited to, screws. Correspondingly, the inner walls of the first openings 113 and the second openings 513 are provided with threads.

[0066] Specifically, the drive mechanism 6 includes a motor, and a worm gear structure or similar can be installed on the motor output shaft 61 to change the output direction, so that the output shaft 61 of the drive mechanism 6 extends along the length of the range hood housing 7. The output shaft 61 of the drive mechanism 6 passes through the first bracket body 211, and the drive mechanism 6 is fixedly connected to the first bracket body 211 by fasteners, including but not limited to screws; the other end of the second rotating member 4 is sleeved on the output shaft 61 of the drive mechanism 6 and rotates synchronously, and the connection between the second rotating member 4 and the drive mechanism 6 constitutes the rotation center of the second rotating member 4.

[0067] In an optional embodiment, such as Figure 6 As shown, the first fixed bracket 21 includes a first connecting flange 214 and a second connecting flange 215. The first rotating member 11 is rotatably connected to the first fixed bracket 21 via a first pin 81. The two ends of the first pin 81 pass through the first connecting flange 214 and the second connecting flange 215 respectively.

[0068] Specifically, a first connecting flange 214 and a second connecting flange 215 are provided opposite to each other on the end of the first fixed edge 213 that is connected to the first rotating member 11. The first connecting flange 214 and the second connecting flange 215 are correspondingly arranged. The first rotating member 11 is located between the first connecting flange 214 and the second connecting flange 215. The first pin 81 passes through the first connecting flange 214, the first rotating member 11 and the second connecting flange 215 in sequence, so that the first rotating member 11 is rotatably connected to the first fixed edge 213 and rotates around the first pin 81, thereby forming a double-sided fixed support structure for the first rotating member 11.

[0083] like Figure 11As shown, during the assembly of the smoke baffle assembly 5, the main structure of the range hood is placed on the assembly table, with the back plate of the range hood housing 7 in contact with the assembly table surface. The rotating component 1 in the aforementioned fixed structure is fixed in the extended state to facilitate assembly. The bracket folds 511 and 521 of the smoke baffle brackets 51 and 52 fixed at both ends of the smoke baffle 53 are inserted into the area between the multiple limiting folds 111 and 121 set on the corresponding rotating component 1, until the positioning protrusions 112 and 122 touch the clearance portions 514 and 524 on the smoke baffle brackets 51 and 52. At this time, the openings 113 and 123 on the rotating component 1 are aligned with the corresponding openings 513 and 523 on the bracket folds 511 and 521. Screws are then driven into the aligned openings to lock the smoke baffle assembly 5 and the range hood housing 7, thus completing the assembly of the smoke baffle assembly 5. Therefore, the limiting flanges 111 and 121 can limit the bracket flanges 511 and 521, effectively fix the smoke baffle assembly 5, and prevent the smoke baffle assembly 5 from flipping and falling. The positioning protrusions 112 and 122 can make the openings on the rotating part 1 and the bracket flanges 511 and 521 aligned, improve the assembly effect, reduce the defect rate, and improve the assembly efficiency.
