The bevel gear 2 15 is meshed and connected with two bevel gears 1 7. When the device is in use, the outdoor ventilation place is connected through the air inlet external pipe 16, and then the multiple fans 3 are started to inlet air, and the outside air is filtered through the filter screen 17 and the filter screen 2 18, and then discharged through the exhaust hood 9. At the same time, the double-axis motor 14 can be started, and the reciprocating screw rod 6 is driven by the bevel gear 1 7 and the bevel gear 2 15, and then the moving plate 8 is driven to slide on the inner side of the moving seat 5, and the exhaust hood 9 is controlled to move, so as to increase the exhaust air outlet range, so that the fresh air exhaust range is wider; The inner left side of the exhaust hood 9 is connected to a plurality of guide plates 10 by a rotating shaft, and the front surface of the exhaust hood 9 is provided with a plurality of connecting plates 11 on both sides of the plurality of guide plates 10, and the connecting plates 11 are connected to the opposite sides of the guide plates 10 by a rotating shaft, and the inner upper surface of the exhaust hood 9 is connected to a flat air outlet 12 by a rotating shaft, and an air outlet hose 13 is fixedly connected between the flat air outlet 12 and the exhaust cylinder 4; The air outlet hose 13 discharges the fresh air discharged from the exhaust tube 4 into the flat air outlet 12, and then discharges it through the exhaust hood 9.
