[0035] The utility model will be described further in detail below in combination with the drawings.

[0036] In the description of the utility model, it is understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, structure and operation, since the disclosed embodiments of the utility model can be arranged in different directions, so these orientation terms are only as an illustration and should not be regarded as a limitation, for example, "upper", "lower" are not necessarily limited to the direction opposite or consistent with the direction of gravity. In addition, the features defined as "first", "second" can explicitly or implicitly include one or more features.

[0037] Referring to Figures 1-2 A range hood includes a smoke collecting cover 1 and an oil cup 2. The bottom of the smoke collecting cover 1 is provided with oil leakage holes 11, and the oil cup 2 is arranged below the smoke collecting cover 1 and used for receiving oil liquid dripping from the oil leakage holes 11 in a front-rear direction moving manner. The top of the oil cup 2 is open to receive the oil liquid. The number of the oil leakage holes 11 in the embodiment is four, and the oil leakage holes 11 are arranged at intervals along the left and right of the bottom of the smoke collecting cover 1.

[0038] Referring to Figures 3-7The range hood further comprises an oil blocking assembly capable of opening or closing the oil leakage holes 11, which is arranged on the inner side of the bottom of the smoke collecting cover 1. The oil blocking assembly comprises the blocking blocks 31, the push rod 32, the second elastic member 33 and the base 34. The number of the blocking blocks 31 corresponds to the number of the oil leakage holes 11, and the blocking blocks 31 can be in a first state of closing the oil leakage holes 11 and a second state of opening the oil leakage holes 11. Each blocking block 31 is connected with the push rod 32, and under the action of the backward movement of the oil cup 2, each blocking block 31 can be moved to the second state by the push rod 32. In the horizontal projection, the blocking blocks 31 and the push rod 32 are located in the oil cup 2, which means that they are located in the top opening of the oil cup 2, i.e. in the range enclosed by the projection contour of the top opening of the oil cup 2. Thus, in the installed state of the oil cup 2, the blocking blocks 31 and the push rod 32 (also including the base 34 described below) of the oil blocking assembly are all located in the oil cup 2, which can ensure that the oil stains cannot drip onto the cooking plate, thereby ensuring the cleanliness of the cooking plate and avoiding the pollution of the objects of cooking operation, such as dishes, cookware, etc.

[0039] The base 34 is arranged on the inner side of the bottom of the smoke collecting cover 1, and the base 34 is provided with a sliding groove 341 for the sliding cooperation of the blocking blocks 31 in the front and back directions, and the sliding groove 341 penetrates the front end of the base 34. In this embodiment, the sliding groove 341 is formed by the upward recess of the lower surface of the base 34, alternatively, the sliding groove 341 can be formed in the interior or the upper surface of the base 34, but in order to avoid the problem of oil leakage caused by the gap between the blocking blocks 31 and the edges of the oil leakage holes 11 when the oil leakage holes 11 are closed, it is preferred that the sliding groove 341 is formed by the upward recess of the lower surface of the base 34, so that the blocking blocks 31 can be tightly attached to the bottom surface of the smoke collecting cover 1. Referring to Figure 5 The left and right sides of the sliding groove 341 are respectively formed with recessed portions 3411 recessed in directions away from each other, and the left and right sides of the blocking blocks 31 are respectively formed with flanges 312 for clamping the corresponding recessed portions 3411, so as to better guide the sliding of the blocking blocks 31.

[0040] The push rod 32 comprises a push rod body 321 extending along the left and right directions of the bottom of the smoke collecting cover 1 and extension portions 322 extending (i.e. downward) from both ends of the push rod body 321 toward the oil cup 2. In the installed state, the push rod body 321 is located above the base 34, and the extension portions 322 are located on the left and right sides of the base 34. In order to facilitate the connection of the push rod 32 and the blocking blocks 31, the push rod body 321 is provided with screw posts 323 extending toward the blocking blocks 31, and the blocking blocks 31 are provided with screw holes 311 corresponding to the screw posts 323, and the screw posts 323 and the blocking blocks 31 are connected by screws 35. The base 34 is provided with avoiding holes 342 for avoiding the screws 35 and allowing the screws 35 to slide forward and backward.

[0041] The second elastic member 33 acts on the block 31, so that the block 31 can keep the movement tendency of moving to the first state towards the front side. The second elastic member 33 is arranged between the rear side of the block 31 and the base 34. In order to define the position of the second elastic member 33, the rear side of the block 31 is provided with a first guide column 313, and the base 34 is provided with a second guide column 343 corresponding to the rear side of the sliding groove 341, and the second elastic member 33 is sleeved between the first guide column 313 and the second guide column 343.

[0042] Referring to Figures 8-12 The bottom of the smoke hood 1 is provided with a hanging member 4 on each of the left and right sides, and the top of the oil cup 2 is formed with a hanging ear 21 extending towards the inner side on each of the left and right sides, and each hanging ear 21 is clamped with the corresponding hanging member 4.

[0043] The hanging ear 21 is provided with an abutting portion 211 capable of abutting against the extension portion 322. The hanging ear 21 is also provided with a limiting hole 212. The hanging member 4 is provided with a limiting mechanism. When the abutting portion 211 drives the extension portion 322 to move backward to make the block 31 in the second state, the limiting hole 212 is limitedly matched with the limiting mechanism. The hanging member 4 is formed with a clamping groove 42 clamped with the hanging ear 21. The limiting mechanism comprises a base 411, a limiting column 412 and a first elastic member 413. The base 411 is arranged on the bottom of the smoke hood 1, the limiting column 412 is arranged in the base 411, and the first elastic member 413 is arranged between the limiting column 412 and the base 411 and keeps the movement tendency of the limiting column 412 moving towards the clamping groove 42. When the block 31 is in the second state, the limiting column 412 is clamped with the limiting hole 212.

[0044] When the oil cup 2 is installed, the abutting portion 211 on the oil cup 2 is matched with the extension portion 322 on the lever 32. Under the driving of the oil cup 2, the lever 32 moves backward, thereby moving the block 31 away and exposing the oil leakage hole 11. After the oil cup 2 is installed in place, the limiting column 412 on the hanging member 4 is matched with the limiting hole 212 on the hanging ear 21 of the oil cup 2, thereby limiting the movement of the oil cup 2 and fixing the block 31. At this time, the second elastic member 33 is in a compressed state.

[0045] When the oil cup 2 is removed, the block 31 is pushed outwards under the elastic force of the second elastic member 33, thereby blocking the oil leakage hole 11, so that the problem that the oil stains on the smoke hood 1 drip from the oil leakage hole 11 when the oil cup 2 is removed can be avoided.
