Lifting type smoke exhaust

The invention relates to a lifting type smoke exhaust. A volute of the lifting type smoke exhaust is contained in the upper portion in a box. A motor, wind wheels and air inflow rings are arranged in the box. The motor is installed in the volute. The wind wheels are fixedly held on the air inflow rings. The air inflow rings are installed on the left side and the right side of the motor respectively and driven by the motor to rotate. The upper portion of the box is covered with an upper glass cover plate. A motor is installed on the lower portion in the box through an installing plate, and the motor and a connecting rod are connected through a gear pair. A driving rod is fixedly held on the connecting rod and driven by the connecting rod. One end of a swing rod is hinged to the driving rod. The other end of the swing rod is hinged to a lifting glass plate. The swing rod can push the lifting glass plate to ascend and descend. An X-type lifting rod is connected between the box and the lifting glass plate. A circle of air suction mesh pieces are arranged on the periphery of the upper edge of the lifting glass plate. The lifting type smoke exhaust has the beneficial effects of being simple in appearance, large in suction force, high in smoke suction speed, convenient to clean and the like.
