The lifting drive motor assembly 640 drives and controls the lifting enclosure 610 to slide up and down.

[0048] The lifting rod 650 is fixedly installed by the fasteners on the lifting enclosure 610. Two or more lifting rods 650 are used, so that the lifting rod 650 is more reliably attached to the lifting enclosure 610, effectively preventing the lifting rod 650 from swinging. In this embodiment, two lifting rods 650 are provided, and the lower end of the lifting rod 650 passes through the top of the smoke hood 100, the connecting seat 111, and the oil guide net 150 and is fixedly connected to the oil tank hanger 620.

[0049] like Fig.10As shown, the oil tank hanger 620 is in the shape of an I, and the intersection of the vertical beam and the horizontal beam of the I is connected to the lifting rod 650. Four oil tank hooks 621 that are symmetrical with each other with the vertical beam as the axis are arranged on the two horizontal beams. The four oil tank hooks 621 correspond to the four buckles 510 on the oil tank 500. This design realizes a detachable connection between the oil tank 500 and the oil tank hanger 620, thereby ensuring that the oil tank 500 is stably fixed and convenient to disassemble and clean.

[0050] When working, the lifting assembly drives the oil tank 500 to descend, so that an air intake port is formed between the oil tank 500 and the flue port.
