[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance that purifies the kitchen environment by exhausting cooking fumes from indoors to outdoors. It typically consists of a smoke collection chamber and a casing assembly. Range hoods are generally installed above the kitchen stove and quickly remove harmful fumes generated during combustion and cooking, venting them outdoors. They also condense and collect the fumes, reducing pollution and purifying the air, and provide safety features such as protection against toxic substances and explosions.

[0003] To prevent cooking fumes from escaping, and to better collect the fumes and cover the smoke inlet when the range hood is not in operation, a flap that can rotate and swing around the hood is usually installed on the smoke collection hood. For example, the flap is fixed to the smoke collection hood using hinges. The first page of the hinge is fixed to the outer shell of the smoke collection hood by screws or welding, and the second page of the hinge is also fixed to the flap by screws or welding.

[0004] However, in the relevant flip-plate technology, fixing the flip-plate requires multiple screws, which leads to installation difficulties, low assembly efficiency, and difficulty in disassembly and cleaning. Utility Model Content

[0046] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0047] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] The following is combined Figures 1 to 5The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0050] The range hood of this utility model includes a range hood body 1 and a flap 2. The range hood body 1 forms a smoke collection hood 11, which is provided with a smoke inlet and a smoke collection chamber. The smoke inlet is connected to the smoke collection chamber. The smoke inlet can draw the oil fumes into the smoke collection chamber and discharge them to the outside environment. The smoke collection hood 11 is provided with a first mounting hole 12 and a second mounting hole 13.

[0051] Combination Figures 1 to 5 The present invention provides a flip-plate rotating assembly, which includes a fixing member, a rotating fixing base 100 and a rotating pin 200.

[0052] The rotating fixed base 100 includes a fixed base 110, a fixed plate 120, a first limiting post 130 and a second limiting post 140, and the fixed base 110 is provided with a pin hole 111 along its own length direction.

[0053] The fixing plate 120 is mounted on the fixing base 110, the first limiting post 130 is mounted on the first end of the fixing plate 120, and the second limiting post 140 is mounted on the second end of the fixing plate 120.

[0054] The rotating pin 200 is rotatably connected to the pin hole 111, and the flap 2 is set on the rotating pin 200, so that the flap 2 can rotate and swing around the rotating fixed base 100.

[0055] The smoke hood 11 is provided with a first mounting hole 12 and a second mounting hole 13, and a second limiting post 140 is hooked and matched with the second mounting hole 13. When the second limiting post 140 is installed with the second mounting hole 13, the second limiting post 140 can hook the second mounting hole 13 to achieve quick installation; when the second limiting post 140 is disassembled from the second mounting hole 13, the second limiting post 140 can be quickly pulled out from the second mounting hole 13; making the installation and disassembly of the rotating fixed base 100 and the smoke hood 11 simpler and more convenient.

[0056] The first limiting post 130 is fixedly connected to the first mounting hole 12 by a fastener; when the first limiting post 130 is installed with the first mounting hole 12, the fastener is used to pass through the first mounting hole 12 and fix it to the first limiting post 130; when the first limiting post 130 is disassembled from the first mounting hole 12, the fastener is removed from the first limiting post 130; this makes the installation and disassembly of the rotating fixed base 100 and the smoke hood 11 more convenient, and the rotating fixed base 100 can be fixed to the smoke hood 11 with a single fastener.

[0057] It is understood that the flip plate rotating assembly provided in the embodiments of this utility model, by setting a rotating fixed base 100, on which a fixed seat 110, a fixed plate 120, a first limiting post 130 and a second limiting post 140 are provided, and a pin hole 111 is provided along the length direction of the fixed seat 110, the flip plate 2 is set on the rotating pin 200, the rotating pin 200 is rotatably connected to the pin hole 111, so that the flip plate 2 can rotate and swing around the rotating fixed base 100; the fixed plate 120 is set on the fixed seat 110, and the first limiting post 130 is set at the first end of the fixed plate 120, the second limiting post 140, the third limiting post 140, the fourth limiting post 140, the fifth limiting post 140, the sixth limiting post 140, the seventh limiting post 140, the eighth limiting post 140, the ninth limiting post 140, the tenth limiting post 140, the eleventh limiting post 15 ... Two limiting posts 140 are set at the second end of the fixing plate 120. The second limiting post 140 is hooked and matched with the second mounting hole 13 on the smoke hood 11. The first limiting post 130 is fixedly connected and matched with the first mounting hole 12 on the smoke hood 11 through a fastener. This allows the second limiting post 140 to be quickly installed or removed from the smoke hood 11. The first limiting post 130 can also be installed with the smoke hood 11 using only one fastener. When removing the first limiting post 130, only this fastener needs to be removed, which saves costs. This makes the fixing and installation of the flip plate 2 simpler, the assembly efficiency higher, and the cleaning and disassembly more convenient.

[0058] Specifically, in combination Figure 3 and Figure 5 In some embodiments of this utility model, the first limiting post 130 is provided with a fixing hole 131, and the fixing member matches the fixing hole 131.

[0059] When the second limiting post 140 is hooked and connected to the second mounting hole 13, the fixing hole 131 is set to correspond to the first mounting hole 12. The fastener can pass through the first mounting hole 12 and be fixedly connected to the fixing hole 131, making it easier and faster to fix the first limiting post 130 to the smoke hood 11, thereby further improving the assembly efficiency of the flip plate.

[0060] In addition, in some embodiments of this utility model, the fastener can be a screw and the fixing hole 131 can be a threaded hole, so that the fastener can be standardized, further reducing costs and facilitating disassembly and assembly.

[0061] Combination Figure 4 In some embodiments of this utility model, the smoke collection hood 11 is provided with a mounting surface 14. When the second limiting post 140 is hooked with the second mounting hole 13 and the first limiting post 130 is fixed in the first mounting hole 12, the fixing plate 120 abuts against the mounting surface 14.

[0062] Moreover, the fixing plate 120 is arc-shaped, and the curvature of the fixing plate 120 matches the curvature of the mounting surface 14. That is to say, the angle formed by the first end and the second end of the fixing plate 120 is the same as the angle formed by the mounting surface 14 of the smoke hood 11. When the rotating fixing base 100 is installed on the smoke hood 11, the fixing plate 120 can fit tightly with the mounting surface 14 of the smoke hood 11, resulting in better installation stability.

[0063] Combination Figure 3 In some embodiments of this utility model, the fixing plate 120 includes a first fixing plate 121 and a second fixing plate 122 that are connected to each other.

[0064] The first limiting post 130 is disposed on the first fixing plate 121, and the second limiting post 140 is disposed on the second fixing plate 122. The curvature of the fixing plate 120 is disposed at the connection between the first fixing plate 121 and the second fixing plate 122. This simplifies the manufacturing of the fixing plate 120, thereby reducing costs and facilitating the installation of the fixing plate 120.

[0065] Combination Figure 3 In some embodiments of this utility model, the second limiting post 140 and the second end of the fixing plate 120 form an acute angle 141 for hooking, so that the second limiting post 140 is hook-shaped; that is, the second limiting post 140 can be an inclined protruding post, which facilitates the fixing and disassembly of the second mounting hole 13 of the smoke hood 11.

[0066] Combination Figure 2 In some embodiments of this utility model, the flip plate rotating assembly further includes a pin sleeve 300, which is disposed on the flip plate 2.

[0067] The flap 2 is rotatably connected to the rotating pin 200 via the pin sleeve 300, allowing the flap 2 to rotate and swing around the rotating fixed base 100, further facilitating the installation and disassembly of the flap 2.

[0068] In addition, combined Figure 2 In some embodiments of this utility model, the flip plate rotating assembly further includes a first pad 400 and a second pad 500.

[0069] The first washer 400 is disposed at the first end of the rotating pin 200, and the second washer 500 is disposed at the second end of the rotating pin 200.

[0070] The first end of the rotating pin 200 is fitted into the pin hole 111, and the second end of the rotating pin 200 is fitted into the pin sleeve 300. This reduces wear between the rotating pin 200 and the rotating fixed base 100, as well as wear between the rotating pin 200 and the pin sleeve 300, thus extending the lifespan of the flip plate rotating assembly.

[0071] Furthermore, combined Figure 3 and Figure 5 In some embodiments of this utility model, the fixing hole 131 is provided at the end of the first limiting post 130. The depth direction of the fixing hole 131 is parallel to the length direction of the first limiting post 130. When the first limiting post 130 corresponds to the first mounting hole 12 of the smoke hood 11, it can be immediately connected to the fixing hole 131 with a fastener to fix the first limiting post 130, making the installation more convenient and quick.

[0072] Combination Figures 1 to 5 In an embodiment of this utility model, a range hood is also provided, which includes the above-mentioned flap rotation assembly, range hood body 1 and flap 2.

[0073] The range hood body 1 has a smoke collection hood 11, which has a smoke inlet and a smoke collection chamber, with the smoke inlet connected to the smoke collection chamber.

[0074] The flap rotation assembly is mounted on the smoke collection hood 11, and the flap 2 is rotatably connected to the flap rotation assembly.

[0075] Of course, the flap rotation assembly can be set in two sets, that is, a rotating fixed base 100 can be set on each side of the smoke collection hood 11 to make the flap 2 more stable.

[0076] It is understandable that the range hood provided by this utility model, due to including the aforementioned flap rotation assembly, inevitably possesses all the advantages of that assembly. That is, the range hood also allows the second limiting post 140 to be quickly installed or removed from the smoke collection hood 11, and the first limiting post 130 can be installed with the smoke collection hood 11 using only one fixing component. Disassembling the first limiting post 130 only requires removing this fixing component, saving costs; thus, the fixing and installation of the flap 2 is simpler, the assembly efficiency is higher, and cleaning and disassembly are also convenient.
