And at least a part of the elongated hole extends to the lower end surface of the second housing 121.

In one embodiment of the present invention, the switch panel assembly 16 is rotatably disposed on the second housing 121, and the switch panel assembly 16 has an open state and a closed state. When the switch panel assembly 16 is in the closed state, the switch panel assembly 16 covers the front surface of the second housing 121, so as to cover the smoke inlet 1211a on the front surface of the second housing 121, and only the smoke inlet 1211a on the lower end surface of the second housing 121 is retained. When the switch panel assembly 16 is in the off state, the switch panel assembly can be suitable for the corresponding state with smaller oil smoke amount, and the space occupied by the main machine 12 of the range hood can be reduced when the switch panel assembly is kept in the off state.

When the panel assembly is switched from the closed state to the open state, the upper end of the panel assembly is pivotally connected to the front panel of the second housing 121, and the panel assembly can also be driven by the driving motor, the output shaft of the driving motor faces the width direction of the front panel of the second interface 132, and during the rotation of the second housing 121, the inner side surface of the panel assembly can be pivoted in the direction away from the front panel of the second housing 121, so that the panel assembly is perpendicular to the front panel of the second housing 121, so that a certain angle is formed between the panel assembly and the front panel of the second housing 121, so as to open the oil smoke inlet 1211a on the front panel of the second housing 121, and increase the area of the oil smoke inlet 1211a. Because the panel component rotates towards the direction far away from the front panel of the second casing 121, the space occupied by the cigarette machine main machine 12 is increased, but the smoke inlet 1211a on the front panel of the second casing 121 is opened, the smoking capacity of the cigarette machine main machine 12 is improved, and the cigarette machine main machine 12 can be suitable for smoking large smoke.

Further, the lower end of the second housing 121 is configured as a trapezoid structure, so that when the oil smoke flows through the oil smoke inlet 1211a, the oil smoke flows to the oil collecting box 161 at the bottom of the trapezoid structure by itself under the action of gravity. Meanwhile, an oil collecting box opening is formed at the upper end of the oil collecting box 161, the width of the oil collecting box opening is larger than the width of the ground of the trapezoid structure, and at least part of the oil collecting box opening is opposite to the oil smoke inlet 1211a in the height direction. So as to ensure that the oil smoke filtered by the oil smoke inlet 1211a positioned on the front side surface of the trapezoid structure can fall into the oil collecting box 161, and prevent the oil smoke from dropping on the table surface.

The first interface 131 of the exhaust fan 13 is communicated with the second air outlet 1112b, and under the action of rotation of the wind wheel, negative pressure is generated at the first interface 131, so as to guide out the air flow passing through the second heat exchange chamber 1112, and meanwhile, the air intake efficiency of the second air return port 1112a can be improved.
