When the polluted air is transmitted to the first air duct 11 through the second air duct 12, the third closing plate 17 at the bottom of the first one-way wind plate 7 blocks the air outlet 3 at the bottom of the first one-way wind plate 7. At the same time, the third closing plate 17 inside the second one-way wind plate 8 will be pushed upward by the wind, so that the dust in the air can only be filtered from the second filter plate 10 at the upper end of the second one-way wind plate 8; when it is necessary to draw outdoor air into the room, the air will be drawn into the first air duct 11 from the air outlet 3 and then blown into the room from the second air duct 12 and the air inlet 2. The outdoor dust will be filtered through the first filter plate 9 at the bottom of the first one-way wind plate 7, so as to achieve the effect of two-way ventilation.

[0022] The side surface of the device body 1 is rotatably connected with the first closing plate 4 and the second closing plate 6. The internal thread of the first closing plate 4 is connected with a bolt 5. The interior of the first filter plate 9 is provided with a handle 18. By removing the bolt 5 and rotating the first closing plate 4 and the second closing plate 6, the first filter plate 9 and the second filter plate 10 are separated from the obstruction of the first closing plate 4 and the second closing plate 6, so that the filter screen can be easily replaced. An air outlet 3 is provided at one end of the device body 1, and an air inlet 2 is provided at the other end of the device body 1. The air inlet 2 and the air outlet 3 can be connected to the ventilation duct.

[0023] Working principle:

[0024] When the device is used, after the polluted air in the room is blown into the second air duct 12 through the air inlet 2, it will be transmitted into the first air duct 11 through the second one-way air plate 8 and then discharged from the air outlet 3. When the polluted air is transmitted to the first air duct 11 through the second air duct 12, the third closing plate 17 at the bottom end of the first one-way air plate 7 blocks the air outlet 3 at the bottom end of the first one-way air plate 7, and at the same time, the third closing plate 17 inside the second one-way air plate 8 will be pushed open by the wind, so that the polluted air can only be discharged from the second filter plate 10 at the upper end of the second one-way air plate 8. Filter dust in the air. Conversely, when it is necessary to draw outdoor air into the room, the air will be drawn into the first air duct 11 from the air outlet 3 and then blown into the room from the second air duct 12 and the air inlet 2. The outdoor dust will be filtered through the first filter plate 9 at the bottom of the first one-way wind plate 7, so as to achieve the effect of two-way ventilation. When the filter needs to be replaced, the bolt 5 is removed and the first closing plate 4 and the second closing plate 6 are rotated to make the first filter plate 9 and the second filter plate 10 break away from the obstruction of the first closing plate 4 and the second closing plate 6, so as to facilitate the replacement of the filter.
