Problems solved by technology

However, since the inner and outer sides of the inner suction cup are both negative pressure chambers, if the inner and outer negative pressure chambers cannot generate enough pressure difference to make the inner suction cup firmly adsorb on the glass, once the outer suction cup fails, the glass-wiping device will be removed from the glass. fall

Embodiment Construction

[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] The glass-wiping device 8 of the present invention includes an adsorption device. The adsorption unit 1 in the adsorption device includes an inner suction cup 11 and an outer suction cup 12 . The cavity inside the inner suction cup 11 forms an inner negative pressure chamber 13 by vacuum suction, and the cavity between the inner suction cup 11 and the outer suction cup 12 forms an outer negative pressure chamber 14 by vacuum suction, wherein the inner suction cup 11 is provided with an atmosphere. A pressure chamber 105 and a through hole 106 , the atmospheric pressure chamber 105 communicates with the atmosphere through the through hole 106 .

[0033] In this embodiment, the inner suction cup includes a connected soft layer and a hard layer, the soft layer is connected to the bottom of the glass-wiping device, the hard...

Abstract

A glass-wiping device (8) comprising a suction unit (1). The suction unit (1) has arranged therein an atmospheric pressure chamber (105) and a through hole (106). The suction unit (1) comprises an inner suction cup (11) and an outer suction cup (12). The inner suction cup (11) is arranged on the inside of the outer suction cup (12). A chamber on the inside of the inner suction cup (11) forms an inner negative pressure chamber (13) via vacuum suction. A chamber between the inner and outer suction cups forms an outer negative pressure chamber (14) via vacuum suction. The inner suction cup (11) has arranged therein the atmospheric pressure chamber (105) and the through hole (106). The atmospheric pressure chamber (105) is in communication with the atmosphere via the through hole (106). The glass-wiping device (8) is also provided with a vacuum pump (15) and an airway (16). The inner negative pressure chamber (13) and the outer negative pressure chamber (14) respectively are connected to the vacuum pump (15) via the airway (16). The suction unit (1) in the present glass-wiping device (8) is capable of generating and maintaining sufficient pressure difference while working, thus effectively preventing the glass-wiping device (8) from falling off the glass while working.

Description

technical field [0001] The invention belongs to the technical field of manufacturing small household appliances for daily use, and in particular relates to a glass-wiping device. Background technique [0002] Traditional glass-wiping devices, such as glass-wiping robots, can work on the glass through adsorption units. A common suction unit consists of a suction cup fixed to the bottom of the glass-wiping device. If the adsorption unit adopts the structure of inner and outer double-layer suction cups, when the glass-wiping device is working, the vacuum pump will pump air continuously to the inner and outer suction cups respectively, so that a negative pressure chamber is formed in the inner suction cup, and an outer negative pressure chamber is formed between the inner and outer suction cups , so that the glass-wiping device is adsorbed on the glass. However, since the inner and outer sides of the inner suction cup are both negative pressure chambers, if the inner and outer...
