The specific operation process comprises the following steps:

after the fan system is started up by the smoke ventilator as shown in fig. 1 and 2, the smoke sensor starts up to detect the front side smoke amount, when the detected data is compared with the built-in stored data, when the detected data is smaller than a threshold value, the default rectifying plate is arranged at the highest position, a gap of 5 mm-20 mm is reserved between the default rectifying plate and the second oil filter screen, the overturning driving mechanism acts, the smoke baffle plate is opened, at the moment, most of the smoke generated by cooking is pulled up by the second air inlet and rises along the side wall of the curved plate, and the smoke baffle plate catches part of the forwardly escaped smoke and enters the smoke ventilator through the first air inlet.

The smoke baffle can effectively prevent the airflow near the side air inlet from continuing to flow upwards, and the traditional side smoke suction machine still has small part of the smoke which is not blocked by the smoke baffle, especially the smoke far away from the side wall of the smoke suction machine.

When a user is stir-fried, the oil smoke quantity is too large, the side-draught mode cannot provide a good oil smoke sucking effect, namely after the value detected by the oil smoke sensor exceeds a threshold value, the first linear motor drives the rectifying plate to descend by 50-200 mm, the space of a smoke collecting area is enlarged, the second linear motor drives the smoke baffle to fold, as shown in fig. 5 and 6, the rotating speed of the fan assembly 72 is increased, the air quantity is increased, and the inlet air speed is prevented from being greatly reduced due to the increase of the air inlet area. At this time, the oil smoke is mainly divided into two lines of side air inlet and upper air inlet, the air inlet congestion condition of a single smoke inlet channel is relieved, the smoke leakage condition when the oil smoke is overlarge is relieved, and all the oil smoke is discharged out of the smoke machine through a fan mechanism after being separated through a second oil filter screen.

The separated oil mainly flows to two parts: most of the oil flows downwards along the side wall of the curved plate and flows into the oil cup at the bottom through the oil leakage hole; a small portion enters the back of the rectifying plate.

As shown in fig. 7, in embodiment 2, the intelligent range hood in this embodiment is mainly directed to a binocular gas cooker, wherein the rectifying plate 5 includes a first rectifying plate 5a and a second rectifying plate 5b disposed on one side of the first rectifying plate 5a, and correspondingly, the lifting driving mechanism includes a first lifting driving mechanism for driving the first rectifying plate 5a and a second lifting driving mechanism for driving the second rectifying plate 5b, and the oil smoke sensor 8a includes a first oil smoke sensor near one side of the first rectifying plate 5a and a second oil smoke sensor near one side of the second rectifying plate 5 b.
