Adsorption device with sucker and window-cleaning device thereof

Abstract

A suction apparatus (1) having a suction cup (11) and a glass-wiping device (8) thereof. The glass-wiping device (8) comprises the suction apparatus (1), a cleaning unit (3), a driver unit (4), a running unit (2), and a control unit (5). The running unit (2) and the cleaning unit (3) are both arranged at the bottom of the glass-wiping device (8). The control unit (5) is connected respectively to the cleaning unit (3) and to the driver unit (4). Under an action of the control unit (5), the driver unit (4) controls the running unit (2) to run. The glass-wiping device (8) sucks onto the surface a glass via the suction apparatus (1). The suction apparatus (1) comprises the suction cup (11). The suction cup (11) comprises a flexible layer (9) and a thin-film layer (10) connected to each other. The flexible layer (9) is connected to the bottom of the glass-wiping device (8). The thin-film layer (10) is for use in contacting and sealing the surface of the glass. The suction unit in the glass-wiping device (8) is capable of affixing securely onto the glass while working, thus effectively preventing the glass-wiping device from falling off the glass while working.

Description

technical field [0001] The invention belongs to the technical field of small household appliances for daily use, and in particular relates to an adsorption device with a suction cup and a glass-wiping device thereof. 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 suction cup is made of soft materials, such as rubber, silica gel, etc., although these elastic materials can make the machine absorb well, but because of their relatively large friction coefficient, the glass-wiping device often cannot overcome the large gap between the suction cup and the glass. The friction causes the glass-wiping device to fail to move, or to run poorly, which affects the performance of the glass-wiping device. Contents of the invention [0003] The technical problem to be solved by the present inv...
