Further improvement of the utility model, described louver frame back is provided with gripper shoe, and motor is installed on the gripper shoe, and the driven wheel of motor passes and the straight-tooth engaged transmission from gripper shoe; The outside of gripper shoe is L shaped flanging, and L shaped flanging is close to the smoke exhaust ventilator cabinet wall, and this L shaped flanging offers guide groove, and tooth plate is provided with projection, and projection stretches in the guide groove, and the motion of projection is retrained by guide groove.
Further improvement of the utility model, the motor outside is provided with motor cover, and described motor cover is fixed on the gripper shoe.
Further improvement of the utility model, louver frame is provided with baffle plate on corresponding to the blinds air-out direction, and described baffle plate offers plurality of air.
Further improvement of the utility model, described air port are that strip also can be square, circle or oval aperture.
Further improvement of the utility model, the inboard of described louver frame is provided with cavity, and the shutter unit is arranged in the cavity, and the driven tooth of shutter unit is stretched out driving straight-tooth engaged transmission with outside tooth plate from the perforate of cavity side.
The beneficial effects of the utility model are: when bleeding, utilize drive unit that each shutter units synchronization is opened, air communication is crossed shutter and is discharged; When not needing to bleed, drive unit cuts out shutter, prevents outdoor insect foreign material in the ventilating opening inlet chamber, and product structure is reasonable, and control is convenient, and reliable transmission is stable, can not influence the operating efficiency of air exhauster in use; Owing to structure unique model novelty, also improved the class of smoke exhaust ventilator.
