[0031] The application will be further described in detail below with reference to the embodiments shown in the drawings.

[0032] 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" and the like is the orientation or positional relationship shown based on the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, since the disclosed embodiments of the utility model can be arranged in different directions, so these orientation indicating 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.

[0033] Referring to Figures 1-3 An extractor hood includes a hood 1 and an oil cup 2. The oil cup 2 is arranged below the hood 1 in a manner capable of moving in the front-rear direction (i.e. the depth direction of the extractor hood, in the installed state of the extractor hood, "front" refers to the side close to the user, and "rear" refers to the side close to the installed wall surface), and is used to receive oil liquid dripping from the hood 1.

[0034] Referring to Figures 2-7 The left and right sides of the bottom of the hood 1 are respectively provided with hanging members 3, and the hanging members 3 and the bottom of the hood 1 are connected through screws 5. The top of the left and right sides of the oil cup 2 is respectively formed with a hanging lug 21 extending in the inward direction, and the hanging member 3 is formed with a clamping groove 31 clamped with the hanging lug 21, and the clamping groove 31 penetrates the hanging member 3 at least at the front side and the outer side (the outer side refers to the left side of the left hanging member 3 and the right side of the right hanging member 3). The hanging member 3 can include a first part 32 and a second part 33 arranged in an up-down manner, and the clamping groove 31 is formed between the first part 32 and the second part 33.

[0035] The limiting mechanism is arranged between the hanging member 3 and the ear 21, and comprises a limiting hole 41, a limiting member 42, an electromagnet 43 and a bracket 44. The limiting hole 41 is arranged on the ear 21. The limiting member 42 is arranged on the hanging member 3, and is in limiting cooperation with the limiting hole 41. The limiting member 42 is in the form of a ring, and is inserted into the clamping groove 31 from top to bottom. At least the first portion 32 is formed with a front-to-back extending sliding groove 34, and the limiting member 42 can pass through the sliding groove 34 and be inserted into the clamping groove 31. In this embodiment, the second portion 33 is also formed with the sliding groove 34. In some cases, when the oil in the oil cup 2 exceeds a certain amount, the oil cup 2 needs to be removed to pour out the oil and clean the oil cup 2. Therefore, the limiting mechanism is further provided with the electromagnet 43, which is arranged on the hanging member 3 and behind the limiting member 42. The electromagnet 43 can attract the limiting member 42 when energized. In order to facilitate the arrangement of the electromagnet 43, a receiving groove 321 is formed on the first portion 32 of the hanging member 3, and the electromagnet 43 is arranged in the receiving groove 321.

[0036] The bracket 44 is used to limit the position of the limiting member 42. The limiting member 42 is arranged on the bracket 44, and the bracket 44 is arranged on the hanging member 3. The bracket 44 comprises a first bracket body 441 and a second bracket body 442. The first bracket body 441 is in the form of a substantially transverse U-shaped. The second bracket body 442 is arranged at the opening of the U-shaped, and forms a lock shape. The limiting member 42 is movably connected with the bracket 44. The limiting member 42 passes through the first bracket body 441, and is always at least partially limited in the space surrounded by the first bracket body 441 and the second bracket body 442. In order to facilitate the installation of the limiting member 42, the first bracket body 441 and the second bracket body 442 are two independent components, and can be connected by inserting the first bracket body 441 into the second bracket body 442. Of course, alternatively, the limiting member 42 can be an open ring, and the first bracket body 441 and the second bracket body 442 can be an integral part. In addition, alternatively, other forms can be used, such as the first bracket body 441 is two parallel arranged connecting rods, and the second bracket body 442 has two ends arranged on opposite ends of the first bracket body 441, etc. As long as the limiting member 42 can move in the front-to-back and up-to-down directions within a certain range relative to the bracket 44, and is always hung on the bracket 44. Since the limiting member 42 is in the form of a ring, when the limiting member 42 moves upward, it also moves backward, and when the limiting member 42 moves downward, it also moves forward.

[0037] Referring to Figure 8 When the oil cup 2 is not installed, at this time the electromagnet 43 is not energized, under the action of the bracket 44 and gravity, the limiting member 42 is in the lowermost and forwardmost position (the forwardmost limit position is limited by the sliding groove 34 and the first portion 441 of the bracket 44).

[0038] Referring to Figure 9, when installing the oil cup 2, the hanging ear 21 of the oil cup 2 is inserted into the clamping groove 31, when contacting the limiting piece 42, the limiting piece 42 is pushed backward by the hanging ear 21 with the continuous pushing of the oil cup 2, and the limiting piece 42 is simultaneously lifted upward. Figure 10 , when the oil cup 2 is installed in place, the limiting piece 42 falls again (with a small forward movement) under the action of the bracket 44 and gravity, and the limiting piece 42 is clamped into the limiting hole 41 on the hanging ear 21, at this time, the oil cup 2 is in a locked state, preventing the oil cup 2 from being knocked off by external factors such as a cooking pot or other processes, so that the oil in the oil cup 2 is splashed out. Preferably, at this time, the center (center) of the limiting piece 42 is below the clamping groove 31, and the limiting piece 42 can also pass through the sliding groove 34 of the second part 33 of the hanging piece 3, so that the position of the limiting piece 42 is more stable, and the oil cup 2 can provide more stable locking effect.

[0039] Referring to Figure 11 , when the oil cup 2 needs to be removed, the electromagnet 43 is energized, the limiting piece 42 moves towards the electromagnet 43 (backward) under the action of the electromagnet 43, and the limiting piece 42 is simultaneously lifted upward with a small amplitude, so that the center of the limiting piece 42 is above the clamping groove 31, the hanging ear 21 of the oil cup 2 moves forward and further lifts the limiting piece 42, and the hanging ear 21 can be separated from the clamping groove 31, so that the oil cup 2 can be removed.
