Background

The range hood has become one of the indispensable kitchen appliances in modern families. The range hood works by utilizing the fluid dynamics principle, a range hood fan is usually arranged in the shell, the range hood fan is used for exhausting the oil smoke, and a filter screen is used for filtering part of grease particles. After the range hood works for a long time, oil can be generated in the range hood, and after the oil is accumulated in the range hood, the oil suction effect and the service life of the range hood can be influenced, so that an oil way in the range hood is required to be designed, and the oil can flow into an oil cup in time. In the prior art, various range hoods for solving the oil way problem are disclosed, such as a range hood disclosed in Chinese patent publication No. 202010007102.1 (issued publication No. CN 111006284B), wherein an oil guiding structure for guiding oil discharged by a fan cover and a fan system into a first air inlet box body is arranged in a fan cover of the range hood, the oil guiding structure comprises an oil storage guiding groove capable of storing the oil, an oil outlet is formed in the oil storage guiding groove, the oil guiding structure further comprises an oil outlet opening and closing mechanism, when the first air inlet box body is in a descending state, the oil outlet opening and closing mechanism opens the oil outlet so that the oil storage guiding groove is communicated with the interior of the first air inlet box body, and when the first air inlet box body is in a state of retracting in the fan cover, the oil outlet opening and closing mechanism closes the oil outlet. Although the oil collecting device of the air inlet assembly is uniformly used for collecting oil in the range hood, the problem of an oil way under a single oil collecting device of the embedded lifting range hood is solved, and the problem of the oil way of the range hood with a single-stage lifting structure is solved. For the range hood with two-stage lifting, the whole structure is not completely fixed, and the problem to be solved is how to ensure the connection reliability and the flow channel tightness of the whole machine in the lifting process, so that the problem of an oil way between an upper box body and a lower box body and the problem of an oil way between the lower box body and an air inlet body are required to be solved. As another example, a "range hood" disclosed in chinese patent No. 202221698878.3 (issued to CN 217876026U) and a "hidden range hood" disclosed in chinese patent No. 201821783223.X (issued to CN 209355322U), both disclose a lifting range hood, and the negative pressure area is moved down by the lowering of the air inlet body, so as to improve the oil fume absorbing effect.
