Description

Fume exhaust fan with lifting function at fume exhaust port Technical Field The invention relates to the technical field of range hoods, in particular to a range hood with a smoke suction port having a lifting function. Background The range hood is an important household appliance used for removing oil smoke generated in the cooking process in a modern kitchen, and has the main function of timely sucking away the oil smoke, steam and peculiar smell in the cooking process so as to keep the air of the kitchen clean. At present, the range hood widely used in the market mainly comprises a top-draft range hood, a side-draft range hood, a lower-draft range hood and the like. The top-draft range hood is most commonly applied to a household kitchen due to the relatively simple structure, attractive appearance and mature installation mode. The existing top-draft range hood is usually arranged right above a cooking bench, a smoke suction opening is arranged at the bottom or lower area of the range hood, negative pressure is formed at the smoke suction opening through an internal fan, and the smoke is sucked into the range hood and discharged outdoors. However, during actual use, the existing top-suction range hood still has the following obvious defects: Firstly, the smoking opening is fixed in position and is positioned at the top of the machine body, and the distance between the smoking opening and the cooker is longer. In the cooking process, the oil smoke is generally just generated above the cooker and is diffused all around, and because a large vertical distance exists between the smoke suction opening and the oil smoke source, the oil smoke is diffused to the surrounding space before being sucked into the smoke suction opening, so that part of the oil smoke is dissipated into the kitchen environment, and the smoking effect is affected. Secondly, because the smoke suction port is higher in position, in order to improve the smoke suction efficiency, the power of a fan is often required to be increased, so that the noise of the range hood is larger in working, the energy consumption is higher, and the use experience and the energy saving requirement of a user are not facilitated. In addition, some prior art is tried to guide the oil smoke to the smoking mouth through setting up smoke guide plate or smoke blocking structure, but this type of smoke guide structure is usually fixed structure or simple flip structure, can't be according to different culinary art operating mode, pan height or user demand and carry out nimble regulation, and the smoke guide effect is limited, and influences operation space or outward appearance aesthetic feeling easily when not using. Moreover, in the existing range hood, the linkage relation between the smoke suction port and the smoke guide structure is simpler, the smoke guide structure which synchronously acts along with the position change of the smoke suction port is generally lacking, the smoke guide path is unstable in the process that the smoke suction port is close to the cooker or far away from the cooker, and the oil smoke still easily escapes from the side face or the front. In summary, the existing top-draft range hood generally has the problems that the smoke suction opening is far away from the smoke source, the smoke is easy to escape, the smoke suction efficiency is limited, the structure adjustment capability is insufficient, and the like, and the energy conservation, low noise and good use experience can not be considered while the smoke suction effect is ensured. Therefore, further improvements are needed. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides the range hood which is simple in structure and low in manufacturing cost, can enable the position of a smoke suction port to be adjustable, and can effectively guide a fume flow path. The invention aims at realizing the smoke exhaust ventilator with the lifting function by adopting the following mode that the smoke exhaust ventilator comprises a main machine, wherein the top of the main machine is provided with a wind cabinet, a smoke exhaust volute is arranged in the wind cabinet, an air inlet of the smoke exhaust volute is communicated with an air duct in the main machine, and smoke exhaust is sucked from the air duct when the smoke exhaust volute works and is discharged outwards through an exhaust seat at the top of the wind cabinet; the bottom of the main machine is provided with a mounting cavity, and a smoke guide assembly is arranged in the mounting cavity; The smoke guide assembly comprises a lifting frame which is arranged on the main machine through a lifting sliding rail, a lifting power device is arranged between the lifting frame and the main machine, and the lifting power device is used for driving the lifting frame to move up and down along the direction limited by the lifting sliding rail; the front end opening of the lifting frame is provided with a
