The invention discloses a
curtain wall natural ventilator comprising an upper frame material, a lower frame material, an air duct upper accessory, an air duct lower accessory, an inner frame material, a base material and a
handle. The upper frame material is connected with a heat insulating rubber strip of the inner frame material, the lower frame material is connected with a heat insulating rubber strip of the base material, the upper frame material is positioned above the base material so as to form a basic ventilating temperature-preserving cavity body, the air duct upper accessory and the air duct lower accessory are arranged in the cavity body so as to form an S-shaped air duct, the inner side of the inner frame material is provided with a top material, a fan material, a
grating and a
grating frame material, the top material is embedded at the upper edge of the inner frame material, the fan material is rotatably connected with the inner frame material through hinge mechanisms at two sides, the
grating and a grating frame material are fixed outside the fan material and cover the whole inner frame material, a stepless speed adjusting gear is arranged between the fan material and the inner frame material, the
handle is rotatably arranged on the fan material, and a
locking mechanism is arranged between the
handle and the inner frame material. The invention has the advantages of
energy conservation,
noise reduction, heat insulation, good safety, and the like, and can realize continuous ventilation and be integrated with a
curtain wall to improve the whole beautifulness.
