Background

The range hood has gone through nearly 20 years in China, and the range hood is developed from the initial top-suction thin range hood to the side-suction deep range hood, and is developed to the conditions of top-suction type disassembly-free and European range hood as the main conditions. The functional structure can be divided into a multimedia range hood, an embedded range hood, a wall-suction type range hood, a near-suction type range hood, a solid wood type range hood and the like. The side-suction type fume exhauster is one machine with side air intake and fume separating technology to separate fume effectively and reach fume exhausting effect. The air inlet of the near-suction type smoke machine is closer to a smoke source, the generated smoke can be locked at the first time, the ascending movement distance of the smoke can be effectively shortened, and the smoke exhaust effect is natural and more ideal, so that the near-suction type smoke machine becomes a common smoke exhaust facility in a modern kitchen. Conventional nearly formula cigarette machine of inhaling on the market is mostly for putting the design in the air intake, for realizing better cigarette effect of holding together, can set up the cigarette board that holds together that can open and shut in putting air intake department usually, makes the range hood can have bigger cigarette space of holding together at the during operation, prevents that the oil smoke from escaping. If a larger cigarette holding space is required, the cigarette holding plate usually adopts a larger area size, the weight of the cigarette holding plate is in direct proportion to the cigarette holding space, and the cigarette holding plate can meet the opening and closing requirements only by correspondingly needing larger pushing force to push a pushing mechanism of the cigarette holding plate inevitably.

The first bracket 51 is used to be mounted on the body 30, and the second connecting portion 22 is rotatably disposed on the first bracket 51. In addition, the pushing mechanism of the range hood further comprises a second bracket 52. The second bracket 52 is adapted to be mounted to the body 30, and the second end 12 is rotatably disposed on the second bracket 52. Thus, the second connecting portion 22 is not directly and rotatably disposed on the body 30, but indirectly and rotatably disposed on the body 30 through the first bracket 51, so that the second connecting portion 22 can be rotatably mounted on the first bracket 51 and then mounted on the body 30 through the first bracket 51, and the assembly operation is simple and rapid; similarly, the second end 12 is not directly and rotatably disposed on the body 30, but indirectly and rotatably disposed on the body 30 through the second bracket 52, so that the second end 12 can be rotatably mounted on the second bracket 52 and then mounted on the body 30 through the second bracket 52, and the assembly operation is simple and fast.

In one embodiment, the second connecting portion 22 is provided with a third shaft hole 221, and the second connecting portion 22 is rotatably connected to the first bracket 51 by the second rotating shaft 15 passing through the third shaft hole 221.
