Abstract
A suction apparatus and a glass-wiping device with the suction apparatus. The glass-wiping device sucks onto the surface of a glass via the suction apparatus. The suction apparatus comprises a suction cup unit (). The suction cup unit () comprises an inner suction cup () and an outer suction cup (). The inner suction cup () is arranged on the inside of the outer suction cup (), where a chamber on the inside of the inner suction cup () forms an inner negative pressure chamber () via vacuum suction, and where a chamber between the inner and outer suction cups (and) forms an outer negative pressure chamber () via vacuum suction. The glass-wiping device sucks onto the surface of the glass via the inner negative pressure chamber () and/or the outer negative pressure chamber (). The glass-wiping device sucks onto the surface of the glass via the suction apparatus, is capable of ensuring sufficient vacuum pressure, and prevents the phenomenon of the glass-wiping device falling from the surface of the glass.
