As shown in fig. 3 and 4, the rotating device 400 is installed on the front side of the smoking assembly 100, the rotating device 400 includes a turntable 420 driven by a motor 410, an revolution shaft 430 is provided on the turntable 420, and the revolution shaft 430 revolves around the rotation axis of the turntable 420. Besides, the rotating device 400 may have other different structures, for example, a rotating shaft (not shown in the drawings) driven by the motor 410 is included, the rotating shaft is connected with a cantilever (not shown in the drawings), the cantilever is provided with a revolving shaft 430, and the revolving shaft 430 revolves around the rotation axis of the rotating shaft. To sum up, the utility model discloses it is not right the concrete structure of rotating device 400 is injectd, as long as rotating device 400 is equipped with revolution axle 430, no matter rotating device 400's structure how, belongs to equally the utility model discloses a protection scope. In order to realize the lifting function of the lifting device 300, a horizontal plate 520 of the lifting unit 500 is provided with a horizontally disposed chute 521, the revolution shaft 430 extends into the chute 521, the lifting device 300 can drive the lifting unit 500 to move up and down through the revolution of the revolution shaft 430, and the lifting unit 500 completes one lifting operation every time the revolution shaft 430 revolves one revolution. In order to avoid interference, the length of the sliding groove 521 is not less than the revolution diameter of the revolution shaft 430. In addition, if the slide groove 521 is disposed to be inclined, the elevating unit 500 may be normally elevated up and down by appropriately adjusting the installation directions of the two elevating slide rails 210 so that the installation direction of the elevating slide rails 210 is orthogonal to the installation direction of the slide groove 521, which is not limited to the above embodiment.

In some embodiments of the present invention, in order to reduce the friction coefficient between the revolution axis 430 and the sliding chute 521, so as to make the lifting device 300 lift more smoothly, the revolution axis 430 is set to rotate freely around itself, i.e. the revolution axis 430 is connected to rotate the turntable 420 or the cantilever, so as to achieve the purpose of converting the sliding friction between the revolution axis 430 and the sliding chute 521 into the rolling friction.

When a user cooks, in order to avoid collision between the head of the user and the oil cup 610 of the range hood, the oil cup 610 is generally disposed at the rear lower part of the range hood. As shown in fig. 2, the first vertical plate 510 and the second vertical plate 530 of the lifting portion 500 are both connected with a connecting rod 601, two connecting rods 601 are both vertically arranged downwards, the ends of the two connecting rods 601 are both connected with an oil cup assembly 600, and the oil cup assembly 600 is located behind and below the smoking assembly 100. In addition, an oil guide plate 700 is installed below the smoke exhaust assembly 200, the oil guide plate 700 is located above the oil cup assembly 600, and the oil guide plate 700 is arranged in a backward tilting manner, so that the oil guide plate 700 can collect oil separated from the smoke exhaust assembly 200 and guide the oil to the oil cup assembly 600. Specifically, oil cup subassembly 600 includes oil cup 610 and joint portion 620, oil cup 610 with joint portion 620 joint makes oil cup 610 releasable connection in joint portion 620 is last, two the end of connecting rod 601 all with joint portion 620 connects. When the lifting part 500 is at the upper limit position, the oil cup assembly 600 is in a normal use state, as shown in fig. 5, the position of the oil cup assembly 600 descends along with the descending of the lifting part 500, and when the oil cup assembly 600 descends to the lower limit position, the inside of the oil cup 610 can be observed by the sight of the user, so that the user can take out the oil cup 610. Because the lifting amplitude of the oil cup assembly 600 depends on the rotation diameter of the revolution shaft 430, and extra cost is not needed to be spent for lifting the rotation diameter of the revolution shaft 430, compared with the prior art, the lifting device 300 has smaller volume and lower cost, and is more beneficial to market popularization.
