[0038] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0039] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0040] Please refer to Figure 1 and Figure 2 This embodiment provides a cavity device 10 connected to the fan system 21 of the range hood, including a cavity 100, a lifting smoke shield device 200, and a flip cover device 300.

[0041] The cavity 100 has an accommodating inner cavity 101 , and an open air inlet 12 is formed at the top of the accommodating inner cavity 101 ;

[0042] The smoke shield lifting device 200 includes a smoke shield 211 and a drive mechanism 212. One end of the drive mechanism 212 can be connected to the smoke shield 211, and the other end can be connected to the cavity 101. The drive mechanism 212 is configured to drive the smoke shield 211 to rise or fall in the accommodating cavity 101 from the bottom to the top.

[0043] The flip cover device 300 includes a flip motor 311 and a flip panel 312. The flip motor 311 can be set at the opening of the cavity 100; the output shaft of the flip motor 311 can be connected to the flip panel 312 to drive the flip panel 312 to rotate and close or open the air inlet 12.

[0044] The cavity device 10 of this solution can independently control the lifting and lowering operations of the smoke baffle 211 and independently control the flipping action of the flip panel.

[0045] The lifting smoke shield device 200 uses a drive mechanism 212 to drive the smoke shield 211 upward or downward within the housing cavity 101. When the smoke shield 211 is raised, it can direct the oil smoke to the fan system 21. When the smoke shield 211 is lowered, it can ensure a smooth operating space on the cabinet countertop. This reduces the impact of convection in the cooking area on the oil smoke path. Furthermore, the lifting smoke shield 211 can reduce the activity of oil smoke flow, improving the range hood's extraction efficiency. The flip cover device 300 uses a flip motor 311 to rotate the flip panel 312 to close or open the air inlet 12. When the air inlet 12 is closed, it prevents the range hood from backflow caused by external airflow. Furthermore, the flip cover device 300 cooperates with the lifting smoke shield device 200 to ensure the smooth raising and lowering of the smoke shield 211 from the air inlet 12, while also ensuring the flatness and sealing of the cabinet countertop and improving the extraction efficiency. Thus, compared with the prior art in which a single linkage structure is used to simultaneously drive the smoke baffle 211 to rise and fall and the flip panel 312 to rotate, this solution is optimized into multiple individually controlled motion structures, which simplifies the complex structure while reducing the difficulty of maintaining the electric components to achieve rapid maintenance.

[0046] Please continue reading Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the detailed structure of the cavity device 10 is as follows:

[0047] The chamber device 10 is provided with an air inlet 12. The airflow channel 11 formed by the chamber device 10 is connected to the fan system 21, ensuring that the smoke passes through the air inlet 12 and is finally discharged through the air outlet 22. The chamber 100 has a rectangular barrel-shaped structure. The middle part of the chamber 100 has a receiving cavity 101. The receiving cavity 101 passes through the top of the chamber 100 to form the air inlet 12. The airflow channel 11 is provided on the bottom side of the chamber 100.

[0048] Optionally, the lifting smoke shield device 200 further includes a decorative panel 400, which is detachably mounted at the air inlet 12. The decorative panel 400 has a mating through-hole 401 directly opposite the air inlet 12, and the flip panel 312 is movably mounted in the mating through-hole 401. The decorative panel 400 and the flip panel 312 cooperate to ensure the air inlet 12 is sealed, thereby preventing the range hood from being affected by external airflow and causing backflow.

[0049] Furthermore, the drive mechanism 212 is a drive motor. In an optional embodiment, the smoke shield lifting device 200 further includes a transmission mechanism 220; the transmission mechanism 220 is arranged from the bottom to the top of the containment chamber 101; the smoke shield 211 is disposed on the transmission mechanism 220; one end of the drive mechanism 212 is disposed on the chamber 100, and the other end is connected to the transmission mechanism 220 to drive the smoke shield 211 to rise or fall within the containment chamber 101. The transmission mechanism 220 can transmit power from the drive mechanism 212 to the smoke shield 211, ensuring smooth raising and lowering of the smoke shield 211.

[0050] from Figure 2 and Figure 3 It can also be seen that in an optional embodiment, the transmission mechanism 220 includes a gear 221 and a rack 223 that are meshed with each other; the rack 223 is arranged in a direction from the bottom to the top of the accommodating inner cavity 101; the rack 223 can be connected to the smoke shield 211; the driving mechanism 212 is connected to the gear 221 to make the smoke shield 211 rise or fall.

[0051] It should be noted that in this embodiment, the gear 221 is shown to rotate, while the rack 223 rises or falls in the direction from the bottom to the top of the accommodating inner cavity 101. In other embodiments of the present invention, the rack 223 may be fixed, while the gear 221 drives the smoke baffle 211 to rise and fall. Regarding the specific structure of the transmission mechanism 220, those skilled in the art should be able to make reasonable selections and designs based on actual needs. No specific restrictions are made here. For example, the transmission mechanism 220 can be a gear chain drive, a belt drive, a screw nut drive, etc. to suit different actual situations. This is just an example. As long as the transmission mechanism 220 can cooperate with the drive mechanism 212 to raise and lower the smoke baffle 211, no specific restrictions are made.

[0052] Furthermore, this embodiment includes two transmission mechanisms 220, which are symmetrically arranged on either side of the inner wall of the accommodating chamber 101. The drive motor is connected to the gears 221 of the two transmission mechanisms 220 via connecting rods 222, respectively, so that both sides of the smoke shield 211 can receive the power to raise and lower, thereby ensuring the smooth lifting and lowering of the smoke shield 211.

[0053] When the output shaft of the driving mechanism 212 rotates, the gear 221 on the connecting rod 222 is driven to rotate, and the gear 221 drives the rack 223 to slide on the slide rail 230, thereby driving the smoke baffle 211 to move up and down.

[0054] like Figure 3 As shown, in an optional embodiment, the smoke shield lifting device 200 further includes a slide rail 230; the slide rail 230 has a fixed side 231 and a sliding side 232, with the sliding side 232 slidably disposed on the fixed side 231. The fixed side 231 is disposed on the inner wall of the chamber 100, extending from the bottom to the top of the accommodating chamber 101; the sliding side 232 is connected to the transmission mechanism 220. In this manner, the slide rail 230 not only ensures smooth lifting and lowering of the smoke shield 211, but also serves as a limiting guide to ensure that the smoke shield 211 can be lifted and lowered from the bottom to the top of the accommodating chamber 101.

[0055] from Figure 3 As can be seen, in an optional embodiment, the lifting smoke shield device 200 further includes a mounting base 240; the smoke shield 211 is detachably mounted in the mounting base 240; and the drive mechanism 212 is connected to the mounting base 240. The mounting base 240 facilitates the installation, removal, and maintenance of the smoke shield 211. Furthermore, the mounting base 240 has a retaining groove with a notch at the top, through which the smoke shield 211 is inserted, thereby achieving a removable connection between the smoke shield 211 and the mounting base 240.

[0056] See also Figure 1 、 Figure 2 and Figure 4 As can be seen from the figure, in an optional embodiment, the flip cover device 300 includes a flip motor 311 and a flip panel 312. The flip motor 311 can be set at the opening of the cavity 100; the output shaft of the flip motor 311 can be connected to the flip panel 312 to drive the flip panel 312 to rotate and close the air inlet 12. A flip motor 311 is separately provided here to drive the rotation of the flip panel 312. Optionally, the flip motor 311 in this embodiment is a rotary motor. It is not difficult to understand that in other embodiments of the present utility model, the flip motor 311 can also be a hydraulic motor, a pneumatic motor, etc. This is just an example and is not limiting.

[0057] In an optional embodiment, the flip cover device 300 further includes a fixed plate 320 and a rotating shaft 321. The flip panel 312 is mounted on the fixed plate 320, which is provided with the rotating shaft 321. The rotating shaft 321 is connected to the output shaft of the flip motor 311. Rotation of the output shaft of the flip motor 311 drives the flip fixed plate 320, thereby driving the flip panel 312. The provision of the fixed plate 320 facilitates the installation, removal, and maintenance of the flip panel 312. The provision of the rotating shaft 321 ensures smooth rotation of the flip panel 312 and simplifies the structure of the flip motor 311.

[0058] Furthermore, a rotation shaft 321 is provided on both sides of the fixed plate 320 in the length direction, and the two rotation shafts 321 are located at the same horizontal line at the lower part of the fixed plate 320 .

[0059] As can also be seen from the figure, in an optional embodiment, the flip cover device 300 further includes a fixing seat 330 and a bearing member 340; the rotating shaft 321 is disposed on the bearing member 340, and the bearing member 340 is connected to the fixing seat 330; the fixing seat 330 is detachably connected to the inner wall of the air inlet 12. This embodiment has two fixing seats 330 and two bearing members 340. The two rotating shafts 321 are respectively connected to the inner rings of the two bearing members 340, and the outer rings of the bearing members 340 are connected to the corresponding fixing seats 330. The flip motor 311 is disposed on one fixing seat 330. This makes it possible to easily perform maintenance on the flip cover device 300 by attaching and detaching the fixing seat 330 to and from the cavity 100.

[0060] When using, Figure 5When the range hood is opened, the flip motor 311 in the flip cover assembly 300 is commanded to rotate, thereby driving the flip panel 312 to open. Once the range hood is opened, the drive mechanism 212 in the lift smoke shield assembly 200 is commanded to rotate, and the connecting rod 222 connected thereto drives the gear 221 to rotate. The rack 223 meshing with the gear 221 drives the sliding side 232 of the slide rail 230 to slide on the fixed side 231. The mounting base 240 connected to the rack 223 drives the lift panel to rise above the air inlet 12. At this point, the lift smoke shield 211 not only reduces the impact of convection in the cooking area on the oil smoke path, but also reduces the activity of oil smoke flow, thereby improving the range hood's extraction efficiency.

[0061] like Figure 6 When the range hood receives a shutdown command, the drive mechanism 212 in the smoke shield lift assembly 200 is instructed to rotate, driving the smoke shield 211 downward into the chamber 100. After the smoke shield 211 returns to its designated position, the flip motor 311 in the flip cover assembly 300 is instructed to rotate, driving the flip panel 312 to close, preventing backflow from the range hood caused by external airflow. If the flip panel 312 malfunctions, the lower decorative panel 400 can be disassembled and the flip panel 312 removed, enabling quick disassembly and maintenance.

[0062] In a second aspect, the present invention provides a range hood, which includes the cavity device 10 of any one of the aforementioned embodiments. Figure 1 As shown, the range hood provided by the present invention comprises a cavity device 10 and a housing device 20. The cavity device 10 is provided with an air inlet 12, and the housing device 20 is provided with a fan system 21 and an air outlet 22. The airflow channel 11 formed by the cavity device 10 is connected to the fan system 21, ensuring that smoke passes through the air inlet 12 and is finally discharged from the air outlet 22.

[0063] Such a down-discharge range hood is arranged in a cabinet, and a mounting opening corresponding to the air inlet 12 is provided on the cabinet countertop, and the decorative panel 400 is arranged at the mounting opening and covers the periphery of the mounting opening.

[0064] In summary, the embodiment of the present invention provides a cavity device 10 and a range hood, which have at least the following advantages:

[0065] Compared with the existing technology that uses a single linkage structure to simultaneously drive the smoke baffle 211 to rise and fall and the flip panel 312 to rotate, this solution is optimized into multiple separately controlled motion structures. While simplifying the complex structure, it reduces the difficulty of maintaining the electric components to achieve rapid maintenance.

[0066] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
