[0040] Compared with the prior art, the top-side double-suction type range hood cancels the extension part extending forward relative to the cabinet 100 and the movable panel controlling the opening and closing of the side smoke inlet 130 in the traditional range hood, directly uses the movable plate 200 to achieve the effect of the extension part and the movable panel, not only greatly reduces the volume of the range hood in the non-use state, but also can simultaneously open or close the top smoke inlet 120 and the side smoke inlet 130, cancels the traditional open-type smoke inlet, can effectively prevent mosquitoes from entering the smoke collecting cavity 110 and effectively prevent the odor in the smoke collecting cavity 110 from seeping out, and greatly improves the user experience.

[0041] It can be understood that the front side of the casing 100 specifically refers to the side of the range hood facing the user when the range hood is in use, so that when the range hood is in use, the movable plate 200 is in the unfolded position, and the second control part 220 faces the user, so that the user can conveniently control the operation of the range hood through the second control part 220. When the range hood is not in use, the movable plate 200 is in the folded position, and the first control part 210 faces the user, so that the user can conveniently control the operation of the range hood through the first control part 210.

[0042] It can be understood that the first control part 210 and the second control part 220 can be touch screen control keys or keys arranged on the surface of the movable plate 200, and in addition, the first control part 210 and the second control part 220 can also be arranged as other control structures, which are not limited in the utility model.

[0043] Referring to Figures 1 to 9 In some embodiments, the actuator includes a driving device arranged in the smoke collecting cavity 110 and in transmission connection with the movable plate 200; when the movable plate 200 is in the unfolded position, the second control part 220 can control the driving device to drive the movable plate 200 to rotate downward relative to the casing 100 to the folded position; when the movable plate 200 is in the folded position, the first control part 210 can control the driving device to drive the movable plate 200 to rotate upward relative to the casing 100 to the unfolded position.

[0044] In the above structure, by electrically connecting the driving device with the first control part 210 and the second control part 220, when the range hood is closed, the movable plate 200 is in the folded position, at this time, the first control part 210 is arranged towards the front of the casing 100, that is, the first control part 210 faces the user, therefore, when the range hood needs to be used, the user can control the driving device to work and drive the movable plate 200 to rotate upward from the folded position to the unfolded position through the first control part 210, so that the second control part 220 is arranged towards the front of the casing 100, that is, the second control part 220 faces the user, and the first control part 210 faces the upper side of the casing 100, therefore, during the use of the range hood, the user can control the operation of the range hood through the second control part 220, and when the range hood needs to be closed, the user can also control the driving device and drive the movable plate 200 to rotate downward from the unfolded position to the folded position through the second control part 220, so that the user's operation and use are more convenient.

[0045] Referring to Figures 1 to 9In some embodiments, the driving device comprises a rotating shaft 230, a motor 240 and a gear assembly 250. The rotating shaft 230 is rotatably installed on the cabinet 100 and connected with the movable plate 200; the motor 240 is installed in the smoke collecting cavity 110 and electrically connected with the first control part 210 and the second control part 220; the gear assembly 250 is installed between the motor 240 and the rotating shaft 230, and the motor 240 can drive the rotating shaft 230 to rotate through the gear assembly 250, thereby driving the movable plate 200 to rotate to the unfolded position or the folded position relative to the cabinet 100.

[0046] By adopting the above structure, the motor 240 drives the rotating shaft 230 to rotate through the driving of the gear assembly 250, thereby driving the movable plate 200 to rotate between the unfolded position and the folded position, so that the turnover of the movable plate 200 is more flexible and smooth, and the arrangement of the gear assembly 250 also facilitates the installation of the motor 240, so that the installation position of the motor 240 in the smoke collecting cavity 110 is more flexible and convenient.

[0048] It can be understood that, in order to realize the rotation of the rotating shaft 230, in addition to the driving gear 251 and the output gear 252 being in mesh with each other, at least one driven gear can also be arranged between the driving gear 251 and the output gear 252, so that the structure of the driving mechanism is more compact and precise, the accurate turnover of the movable plate 200 is facilitated, and the installation position of the motor 240 can also be more flexibly adjusted.

[0049] It can be understood that the output gear 252 is arranged on the rotating shaft 230. Specifically, the output gear 252 can be fixedly installed on the rotating shaft 230, or the output gear 252 and the rotating shaft 230 can also be arranged as an integral structure, which is not limited in the utility model.

[0050] With reference to Figures 1 to 9 In some embodiments, the rotating shaft 230 is installed in the smoke collecting cavity 110, and the top of the movable plate 200 is provided with two connection ears 260 arranged upwardly and protruding. The two connection ears 260 are arranged in the length direction of the movable plate 200 and are correspondingly connected to the two ends of the rotating shaft 230.

[0051] By adopting the above structure, the rotating shaft 230 can be limited inside the smoke collecting cavity 110, so as to not only protect the rotating shaft 230 and reduce the risk of damage of the rotating shaft 230, but also avoid affecting the overall appearance of the range hood due to the exposure of the rotating shaft 230 outside the machine shell 100. By arranging two connecting ears 260 on the top of the movable plate 200 and mounting the two connecting ears 260 on the two ends of the rotating shaft 230, the mounting and fixing between the movable plate 200 and the rotating shaft 230 can be facilitated, and the overturning of the movable plate 200 is more stable.
