Abstract
The application provides a fresh air purification window for preventing haze. A ventilation device is provided with an upper layer and a lower layer and partitioned by a transverse middle-layer partition plate, an exhaust fan is mounted in the upper layer, an air feeder is mounted in the lower layer, an air inlet grille is formed on the upper layer through front-layer glass, and a half-closed space with an air cavity unidirectionally provided with an exhaust opening is formed by the upper layer, upper-layer glass, a middle-layer separation partition plate and air cavity one-sided glass. The fresh air purification window has the effects of lowering the shielding light ray of the current purification window and enabling the current purification window to be compact in structure.
