[0054] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0055] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an" and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing" and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless the order of performance is expressly stated. It should also be understood that additional or alternative steps may be used.

[0056] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first", "second", and other numerical terms used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0057] For ease of description, spatial relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "over", etc. Such spatial relative relationship terms are intended to include different orientations of the device in use or operation other than the orientations depicted in the figure. For example, if the device in the figure is flipped, then an element described as "below" or "beneath" other elements or features will subsequently be oriented as "above" or "over" other elements or features. Thus, the example term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0058] As Figures 1 to 3 shown, an embodiment of the first aspect of the present invention provides an air inlet assembly 100, which includes a support frame 10, an air duct body 20, and a lifting device 30. Specifically, an installation opening 11 is formed on the support frame 10, the air duct body 20 is defined in the installation opening 11 in a slidable manner, the lifting device 30 is installed on the support frame 10, and the lifting device 30 is connected to the air duct body 20 to drive the air duct body 20 to rise or fall relative to the support frame 10.

[0059] According to the air inlet assembly 100 of the embodiment of the present invention, which includes a support frame 10, an air duct body 20, and a lifting device 30, the air duct body 20 can be driven to rise or fall by the lifting device 30. The air inlet assembly 100 of the embodiment of the present invention is used for a combined device with an oil fume suction device and a cooking appliance, and as the air inlet end of the oil fume suction device, the air inlet assembly 100 can be specifically arranged on the cooking top 200 of the cooking appliance. When the oil fume suction device is not started, the air duct body 20 can be controlled to be in a low position, that is, the upper end opening of the air duct body 20 is not higher than the surface of the cooking top 200. When the oil fume suction device is started, the air duct body 20 can be controlled to rise, so as to reduce the distance between the air duct body 20 and the cooking utensil, and improve the oil fume suction effect of the oil fume suction device.

[0060] In some embodiments of the present invention, in combination with Figure 4 shown, the lifting device 30 includes a transmission mechanism 32, in combination with Figures 5 to 8As shown in the figure, the transmission mechanism 32 includes a first swing arm 321, a second swing arm 322, a first support rod 323 and a second support rod 324. A first meshing tooth 3211 is formed at one end of the first swing arm 321, and a second meshing tooth 3221 is formed at one end of the second swing arm 322. The second meshing tooth 3221 meshes with the first meshing tooth 3211. One end of the first support rod 323 is connected to the other end of the first swing arm 321, and one end of the second support rod 324 is connected to the other end of the second swing arm 322. Both the first support rod 323 and the second support rod 324 are parallel to the central axis of the rotating shaft of the motor 30. The first support rod 323 is clamped in a first card slot 21 provided at the lower end of the air duct body 20, and the second support rod 324 is clamped in a second card slot (not shown in the figure) provided at the lower end of the air duct body 20. The first card slot 21 and the second card slot are both provided on the outside of the air duct body 20 and are arranged in a way that they are away from each other.

[0061] In this embodiment, due to the meshing relationship between the first meshing tooth 3211 and the second meshing tooth 3221, the first swing arm 321 can drive the second swing arm 322 to swing synchronously. During this process, the first swing arm 321 and the second swing arm 322 drive the first support rod 323 and the second support rod 324 to move respectively. The movement of the first support rod 323 and the second support rod 324 includes both a vertical component and a horizontal component. Among them, the vertical component drives the air duct body 20 to rise or fall, and the horizontal component is converted into the sliding of the first support rod 323 in the first card slot 21 and the sliding of the second support rod 324 in the second card slot. This transmission mechanism 32 in this embodiment occupies less space in the vertical direction. In addition, since the components of the transmission mechanism 32 are all arranged outside the air duct body 20, it will not cause a reduction in the air intake area, so it has a relatively high oil fume suction efficiency.

[0062] In some embodiments of the present invention, the lifting device 30 further includes a motor 31. The motor 31 is connected to the air duct body 20 through the transmission mechanism 32. The motor 31 is installed on the support frame 10. Thus, taking the motor 30 as the power source, the air duct body 20 is controlled to rise and fall through the transmission mechanism 32. Further, the rotating shaft of the motor 31 can be connected to the first swing arm 321 to directly drive the first swing arm 321 to swing.

[0063] In some embodiments of the present invention, the transmission mechanism 32 further includes a third swing arm 325 and a fourth swing arm 326. A third engaging tooth 3251 is formed at one end of the third swing arm 325. The other end of the third swing arm 325 is connected to the other end of the first support rod 323. A fourth engaging tooth 3261 is formed at one end of the fourth swing arm 326. The fourth engaging tooth 3261 meshes with the third engaging tooth 3251. The other end of the fourth swing arm 326 is connected to the other end of the second support rod 324. In this embodiment, the third swing arm 325 and the fourth swing arm 326 are respectively connected to the other ends of the first support rod 323 and the second support rod 324. Thus, the first swing arm 321, the second swing arm 322, the first support rod 323, and the second support rod 324 are combined into a closed structure surrounding the outside of the air duct body 20, which can improve the structural stability of the transmission mechanism 32.

[0064] In some embodiments of the present invention, as shown in Figure 9 FIG. 5, the air inlet assembly 100 further includes two locking members 40. The locking member 40 includes: a locking body 41, a mounting shaft 42, and a torsion spring 43. The mounting shaft 42 is disposed on the air duct body 20. The locking body 41 is rotatably connected to the mounting shaft 42. The torsion spring 43 is sleeved on the mounting shaft 42. One end of the torsion spring 43 abuts against the locking body 41. When the locking member 40 is in the locked state, a part of the structure of the locking body 41 extends in the horizontal direction to form a first card slot 21 or a second card slot with the bottom end face of the air duct body 20.

[0065] In this embodiment, both the first card slot 21 and the second card slot are formed by the locking member 40. In this way, it is beneficial to the installation and disassembly between the air duct body 20 and the transmission mechanism 32. Specifically, applying pressure to the part of the locking body 41 that extends in the horizontal direction causes it to flip downward. In this state, it is easy to separate the transmission mechanism 32 from the air duct body 20. Conversely, if assembling the transmission mechanism 32 and the air duct body 20, first apply pressure to the part of the locking body 41 that extends in the horizontal direction to make it flip downward, then the transmission mechanism 32 is sleeved outside the air duct body 20, and the first support rod 323 and the second support rod 324 are kept at a position slightly higher than the locking body 41. After that, release the applied pressure, and the locking body 41 enters the locked state under the action of the torsion spring 43, so that the first support rod 323 and the second support rod 324 respectively fall into the first card slot 21 and the second card slot.

[0066] In some other embodiments of the present invention, the transmission mechanism 32 can also adopt other structural forms. For example, the transmission mechanism 32 can include a gear and a rack. Among them, the gear is fixedly connected to the rotating shaft of the motor 31, and the rack is fixedly connected to the air duct body 20, and the rack meshes with the gear. In this embodiment, the transmission between the motor 31 and the air duct body 20 can also be realized through the transmission mode of the gear and the rack.

[0067] In some other embodiments of the present invention, the lifting device 30 can also be an equipment with a lifting function as a whole. For example, using an electric push rod as the lifting device 30 can also realize the function of driving the air duct body 20 to rise and fall.

[0068] In some embodiments of the present invention, the air inlet assembly 100 further includes an inlet grille 50. The inlet grille 50 is detachably installed at the top end of the air duct body 20. The inlet grille 50 can protect the upper opening of the air duct body 20. The most common protection function is to prevent larger objects from falling into the air duct body 20 and causing blockage of the air duct body 20.

[0069] In some embodiments of the present invention, a card slot 51 is provided at the bottom edge of the inlet grille 50. Correspondingly, a protruding member 22 is provided on the inner wall of the upper end of the air duct body 20. The inlet grille 50 can be rotated relative to the air duct body 20 to make the protruding member 22 enter or escape from the card slot 51. Thus, the connection or disassembly between the inlet grille 50 and the air duct body 20 is realized. This connection and disassembly method has the advantage of convenient operation.

[0070] In some embodiments of the present invention, a plurality of ventilation holes 23 are provided on the side wall of the air duct body 20. The upper opening of the air duct body 20 can suck in oil fume from top to bottom, and the ventilation holes 23 can suck in oil fume from outside to inside in the radial direction. Thus, the process of sucking oil fume from multiple angles and directions is realized to improve the oil fume suction effect.

[0071] An embodiment of the second aspect of the present invention provides a combined device with an oil fume suction device and a cooking appliance, which includes the air inlet assembly 100 in any of the above embodiments.

[0072] According to the combined device with an oil fume suction device and a cooking appliance of the embodiment of the present invention, the air inlet assembly 100 is used as the air inlet end of the oil fume suction device. Specifically, the air inlet assembly 100 can be arranged on the cooking range 200 of the cooking appliance. When the oil fume suction device is not started, the air duct body 20 can be controlled to be in a low position, that is, the upper opening of the air duct body 20 is not higher than the tabletop of the cooking range 200. When the oil fume suction device is started, the air duct body 20 can be controlled to rise, so as to reduce the distance between the air duct body 20 and the cooking utensil and improve the oil fume suction effect of the oil fume suction device.

[0073] Furthermore, the combined device with an oil fume suction device and a cooking appliance further includes a cooking appliance and an oil fume suction device. The cooking appliance includes a cooking range 200, and an installation opening 210 is provided on the cooking range 200. The air inlet assembly 100 is disposed in the installation opening 210. When the oil fume suction device is not started, the air duct body 20 does not extend out of the installation opening 210, thereby avoiding the collision between the cooking utensil and the air duct body 20 during the process of the user taking the cooking utensil. It is only necessary to control the air duct body 20 to extend out of the installation opening 210 when the oil fume suction device is started, so that the upper opening of the air duct body 20 rises, and thus a better oil fume suction effect is achieved.

[0074] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
