[0049] In the prior art, an oil cup is usually used to collect the oil liquid formed by the condensation of oil smoke in the range hood. The oil cup is arranged below the range hood body and is detachably connected to the range hood body. When cleaning the oil cup, the oil cup needs to be removed from the range hood body and cleaned. After cleaning, the oil cup is installed on the range hood body. However, the oil cup is usually located on the side of the range hood close to the wall. The oil cup is far away from the position where the user stands, and the height of the oil cup is usually high. When removing the oil cup, the user needs to lean forward and tiptoe to reach the oil cup, and needs to maintain this state to remove the oil cup. When installing the oil cup, the user also needs to lean forward and tiptoe to install it, which makes it inconvenient to remove and install the oil cup.

[0050] Based on this, the present application provides an oil cup structure, including an oil cup, a lifting member and a rotating member. The rotating member is rotatably arranged on the shell of the range hood, and the rotating member is inserted on the lifting member. When the oil cup needs to be removed, the rotating member is rotated along the axis of the rotating member to drive the lifting member and the oil cup to descend, thereby reducing the distance between the oil cup and the user, bringing the oil cup closer to the user, thereby facilitating the user to install and remove the oil cup.

[0051] The following describes the embodiments of the present utility model in conjunction with the accompanying drawings.

[0052] Reference Figure 1 , Figure 7 and Fig.15 As shown, the embodiment of the present application provides an oil cup structure for a range hood, the oil cup structure comprising: an oil cup 100, a lifting assembly 200 and a driving assembly 300, the lifting assembly 200 comprising a lifting member 210, the oil cup 100 and the lifting member 210 being detachably connected. The driving assembly 300 comprises a rotating member 310, the rotating member 310 being rotatably arranged on a housing 600 of the range hood, the rotating member 310 being inserted on the lifting member 210, the rotating member 310 rotating relative to the lifting member 210, so as to drive the oil cup 100 to rise or fall through the lifting member 210.

[0053] The oil cup 100 is located outside the housing 600 of the range hood, and the oil cup 100 is detachably connected to the bottom of the lifting member 210 so that the oil cup 100 can be removed from the lifting member 210, thereby facilitating cleaning of the oil cup 100.

[0054] In a specific implementation, the oil cup 100 is usually in an ascending position, at which time the lifting member 210 is completely located in the housing 600 of the range hood. When the oil cup needs to be removed, the rotating member 310 is rotated along its axis and in a first direction to drive the lifting member 210 to descend, and at the same time, the lifting member 210 drives the oil cup 100 to descend to a preset position. At this time, the lifting member 210 is partially located outside the housing 600 of the range hood, and the distance between the oil cup 100 and the user is reduced, and the user can remove the oil cup 100 from the lifting member 210. After the oil cup 100 is cleaned, the oil cup 100 is connected to the lifting member 210, and the rotating member 310 is rotated along its axis and in a second direction opposite to the first direction to drive the lifting member 210 to ascend, and the lifting member 210 drives the oil cup back to the ascending position. It can be understood that the preset position of the oil cup 100 can be adjusted by controlling the rotation amount of the rotating member 310.

[0055] The oil cup structure provided in the embodiment of the present application is provided with a rotating member 310 and a lifting member 210. When the oil cup 100 needs to be removed, the rotating member 310 is rotated along the axis of the rotating member 310 to drive the lifting member 210 and the oil cup 100 to descend, thereby shortening the distance between the oil cup 100 and the user and bringing the oil cup 100 closer to the user. The user does not need to lean forward and stand on tiptoe when removing and installing the oil cup 100, thereby making the removal and installation of the oil cup 100 more convenient.
