Therefore, they should not be construed as limitations on this application.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] like Figures 1 to 6 As shown, this application provides a range hood bracket, which includes a fixed base 1, a rotating nut 2, an active rotating member 3, and a screw 4. The fixed base 1 can be installed on an external component. The fixed base 1 is provided with a through cavity 11 extending in the vertical direction and a first mounting hole 12 extending in the horizontal direction, the first mounting hole 12 communicating with the through cavity 11. The rotating nut 2 is rotatably connected to the inner wall of the through cavity 11, and the rotating nut 2 is provided with a first tooth 21. The active rotating member 3 is rotatably connected to the inner wall of the first mounting hole 12, and the active rotating member 3 is provided with a second tooth 31, the second tooth 31 meshing with the first tooth 21, so that the rotating nut 2 can be rotated by the rotation of the active rotating member 3. The screw 4 passes through the rotating nut 2 and the through cavity 11, and is screwed to the rotating nut 2. The screw 4 is provided with a mounting member 5, which can be used to install a range hood.

[0045] The range hood bracket is installed in the required position using the fixed base 1. Then, by rotating the active rotating part 3, the rotating nut 2 is rotated through the meshing between the first tooth 21 and the second tooth 31. Since the screw 4 is screwed onto the rotating nut 2, and the rotating nut 2 is connected to the fixed base 1, the rotation of the rotating nut 2 drives the screw 4 to rise and fall, thereby driving the range hood on the mounting part 5 to rise and fall. The range hood bracket has improved load-bearing strength through the double self-locking mechanism of the meshing between the first tooth 21 and the second tooth 31 and the screw connection between the rotating nut 2 and the screw 4.

[0046] In addition, the range hood bracket can also adjust the height of the air inlet of the range hood by adjusting the screw during later use, thereby improving the smoke exhaust efficiency.

[0047] In existing technologies, the weight of a range hood is generally between 30kg and 40kg. To further ensure load-bearing capacity, in some embodiments, the diameter of the screw 4 is greater than or equal to 15mm. The active rotating component 3 is a cylindrical body, and the dimensions of the rotating nut 2 and the active rotating component 3 are matched with the dimensions of the screw 4, and are as large as possible. The rotating nut 2 and the active rotating component 3 can be connected to the fixed base 1 via bearings disposed in the through cavity 11 and the first mounting hole 12. In some embodiments, two first mounting holes 12 are provided, and each first mounting hole 12 is provided with an active rotating component 3, that is, by providing two active rotating components 3, the load-bearing strength is further improved.

[0048] like Figure 1 , Figure 3 and Figure 5 As shown, the rotation axis of the rotating nut 2 is perpendicular to the rotation axis of the driving member 3. Based on this, in some embodiments, the rotating nut 2 has the aforementioned first tooth 21 on one end face in the vertical direction. Correspondingly, the rotation axis of the driving member 3 is perpendicular to the rotation axis of the rotating nut 2, and the driving member 3 has the aforementioned second tooth 31 on one end face facing the through cavity 11. When the driving member 3 rotates, the second tooth 31 can push the first tooth 21 on the rotating nut 2, thereby driving the rotating nut 2 to rotate. Exemplarily, both the first tooth 21 and the second tooth 31 include multiple protruding teeth. The multiple protruding teeth are arranged circumferentially along the end face of the driving member 3 facing the through cavity 11 or the end face of the rotating nut 2 in the vertical direction. The protruding teeth extend perpendicularly along the rotation axis of the driving member 3 or the rotation axis of the rotating nut 2. In some alternative embodiments, the first tooth 21 and the second tooth 31 can also be replaced by the tooth profile of a bevel gear.

[0049] like Figures 3 to 6As shown, in some embodiments, the end of the active screwdriver 3 away from the second tooth 31 protrudes from the first mounting hole 12, thereby facilitating the application of force by external tools to the active screwdriver 3 and making it easier to screw. To further facilitate the screwing of the active screwdriver 3, a force-applying part 32 is provided at the end of the active screwdriver 3 away from the second tooth 31 to facilitate the application of force to the active screwdriver 3. The force-applying part 32 is not specifically limited. For example, the end of the active screwdriver 3 away from the second tooth 31 has a groove for screwing with a screwdriver, forming the aforementioned force-applying part 32; or, the outer peripheral surface of the end of the active screwdriver 3 away from the second tooth 31 has a clamping plane for clamping with a wrench, forming the aforementioned force-applying part 32.

[0050] like Figure 7 As shown, in some embodiments, the range hood bracket further includes a drive component 6. The output end of the drive component 6 is connected to the active rotating component 3. The output end of the drive component 6 and the active rotating component 3 can be fixedly connected by welding or detachable connection such as a snap-fit. Through the automatic drive of the drive component 6, the active rotating component 3 is rotated, thereby driving the lifting and lowering of the mounting component 5, saving manual labor in turning the active rotating component 3. Exemplarily, the drive component 6 can be, but is not limited to, a motor.

[0051] like Figure 1 As shown, in some embodiments, the mounting base 1 is provided with a second mounting hole 13, through which the mounting base 1 can be fixed to an external component by screws or bolts. For example, the external component can be a wall or a cabinet. In other embodiments, the mounting base 1 may also be provided with components such as hooks.

[0052] like Figure 1 As shown, in some embodiments, the mounting component 5 is provided with a mounting groove 51, which is strip-shaped and extends along the axial direction perpendicular to the screw 4. This allows the mounting plate 7 with mounting holes of different spacings to be bolted onto the mounting component 5, thus making it suitable for different models and brands of range hoods, expanding its applicability and improving its versatility. Furthermore, when replacing the range hood, there is no need to move or replace the mounting component 5; only the different mounting plates 7 need to be replaced, making replacement convenient. In some embodiments, such as... Figures 8 to 10 As shown, the mounting plate 7 is provided with a third mounting hole 72. Bolts are passed through the third mounting hole 72 and the mounting groove 51, and tightened with nuts to fix the mounting plate 7 to the range hood bracket. The mounting plate 7 is also provided with hooks 71, which cooperate with the hanging parts on the range hood to fix the range hood to the mounting plate 7.

[0053] This application provides a range hood, which includes a range hood and the aforementioned range hood bracket. The range hood can be installed on the mounting part 5, thereby improving the load-bearing strength through the meshing between the first tooth 21 and the second tooth 31 and the screw connection between the rotating nut 2 and the screw 4.

[0054] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0055] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
