[0036] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0037] The utility model provides a range hood, see Figures 1 to 8 The range hood comprises a range hood body 1, a telescopic panel assembly 2, an oil cup 3 and a driving mechanism.

[0038] The hood body 1 has an installation cavity a and an oil guide cavity b. The side of the installation cavity a facing the user is connected to the outside. The telescopic panel assembly 2 is arranged in the installation cavity a, wherein the telescopic panel assembly 2 is used to control the functions including turning on and off the hood, the size of the smoking power, and lighting. At the same time, at least one of a lighting device, an air curtain assembly, and a PM2.5 detection unit can be installed in the telescopic panel assembly 2. In order to illuminate the stove through the lighting device, the air curtain assembly forms a wind wall to isolate the oil smoke, and the PM2.5 detection unit performs safety detection on PM2.5 in the kitchen.

[0039] The oil cup 3 is arranged below the oil guide cavity b. The driving mechanism is arranged in the range hood body 1, and has a first motion state of driving the telescopic panel assembly 2 to extend or retract into the mounting cavity a and a second motion state of driving the oil cup 3 to rise or fall relative to the bottom of the oil guide cavity b.

[0040] The utility model installs the telescopic panel assembly 2 in the installation cavity a of the hood body 1 through the arrangement of the hood body 1, the telescopic panel assembly 2, the oil cup 3 and the driving mechanism. When the user uses the hood, the first movement state of the driving mechanism is utilized to drive the telescopic panel assembly 2 to extend out of the installation cavity a, and the telescopic panel assembly 2 blocks the oil smoke. The hood body 1 can absorb the oil smoke below the telescopic panel assembly 2, and the oil formed by the hood body 1 enters the oil guide cavity b and then drips into the oil cup 3, thereby increasing the smoking range of the hood body 1 and reducing the escape of the oil smoke. Similarly, when the user is not using the hood, the first movement state of the driving mechanism is utilized to drive the telescopic panel assembly 2 to retract into the installation cavity a. The installation cavity a not only protects the telescopic panel assembly 2 and reduces dust falling on the telescopic panel assembly 2, but also makes the hood more concise and beautiful, saving kitchen space. In addition, an oil cup 3 is installed below the oil guide chamber b of the range hood body 1, and the second motion state of the driving mechanism is used to drive the oil cup 3 to rise relative to the bottom of the oil guide chamber b. The oil cup 3 is close to the bottom of the oil guide chamber b, reducing the distance between the oil cup 3 and the oil guide chamber b, thereby preventing oil stains from dripping onto other places in the kitchen; when the user needs to clean the oil cup 3, the second motion state of the driving mechanism is used to drive the oil cup 3 to descend relative to the bottom of the oil guide chamber b. The oil cup 3 is away from the bottom of the oil guide chamber b, shortening the distance between the oil cup 3 and the user, thereby facilitating the user to remove the oil cup 3 for cleaning.

[0041] Based on the above examples, please refer to Figure 5 and Figure 6In another embodiment, the driving mechanism includes a panel driving assembly 4 and an oil cup driving assembly 5, wherein both the panel driving assembly 4 and the oil cup driving assembly 5 can be a crank slider mechanism. In the first motion state, the panel driving assembly 4 drives the telescopic panel assembly 2 to extend or retract into the installation cavity a; in the second motion state, the oil cup driving assembly 5 drives the oil cup 3 to rise or fall relative to the bottom of the oil guide cavity b. Through the arrangement of the panel driving assembly 4 and the oil cup driving assembly 5, when the user uses the range hood, the panel driving assembly 4 drives the telescopic panel assembly 2 to extend out of the installation cavity a, and the telescopic panel assembly 2 blocks the oil fume, so that the range hood body 1 can absorb the oil fume under the telescopic panel assembly 2, thereby increasing the range of the range hood body 1 to absorb the oil fume and reducing the escape of the oil fume. When the user is not using the range hood, the panel driving assembly 4 drives the telescopic panel assembly 2 to retract into the installation cavity a, which not only protects the telescopic panel assembly 2 and reduces dust falling on the telescopic panel assembly 2, but also makes the range hood more concise and beautiful, saving kitchen space. In addition, the oil cup driving assembly 5 is used to drive the oil cup 3 to rise relative to the bottom of the oil guide chamber b. The oil cup 3 is close to the bottom of the oil guide chamber b, reducing the distance between the oil cup 3 and the oil guide chamber b, thereby preventing oil stains from dripping onto other places in the kitchen. Similarly, when the user is not using the range hood, the oil cup driving assembly 5 is used to drive the oil cup 3 to descend relative to the bottom of the oil guide chamber b. The oil cup 3 is away from the bottom of the oil guide chamber b, shortening the distance between the oil cup 3 and the user, thereby making it easier for the user to remove the oil cup 3 for cleaning.

[0042] Based on the above examples, please refer to Figures 5 to 8 In another embodiment, an oil outlet 121 is provided at the bottom of the oil guide chamber b, and the oil cup driving assembly 5 is provided in the oil guide chamber b. The oil cup driving assembly 5 includes a first driving member 51 and a lifting frame 52.

The driving end of the first driving member 51 is connected to the lifting frame 52 to drive the lifting frame 52 to extend or retract into the oil guide chamber b through the oil outlet 121, and the oil cup 3 is connected to the bottom of the lifting frame 52. When the user uses the range hood, the user utilizes the driving end of the first driving member 51 to drive the lifting frame 52 to retract into the oil guide chamber b through the oil outlet 121. After the oil formed by the oil smoke sucked into the range hood body 1 enters the oil guide chamber b, the oil drips into the lifting frame 52. The oil at the bottom of the lifting frame 52 then flows into the oil cup 3 for collection, thereby facilitating the centralized collection of the oil in the range hood and reducing the oil flowing along the inner wall of the oil guide chamber b and entering the internal gaps of the various structures of the range hood.

[0043] Based on the above examples, please refer to Figures 5 to 8In another embodiment, the oil cup drive assembly 5 further includes a first guide rail assembly 53, a guide rail bracket 15 is provided in the oil guide cavity b, a fixed rail of the first guide rail assembly 53 is provided on the guide rail bracket 15, and a movable rail of the first guide rail assembly 53 is provided on the lifting frame 52 and is slidably connected to the fixed rail.
