Abstract

The invention relates to a wall-cleaning robot based on the positive and negative pressure absorption principle. The wall-cleaning robot of the invention solves the problems of complicated structure, bad wall absorption effect, and bad obstacle-crossing capacity and so on, existing in the existing wall-cleaning robot. A cleaning mechanism (71) and a water inlet and outlet mechanism of the invention are installed in a shell body (2); a wheel type traveling system (70) is installed at the lower part of the shell body (2); a three-phase motor (13) is installed on the upper end face of the shell body (2); the outer rotors of the three-phase motor (13) are respectively and fixedly provided with a propeller (1) and a centrifugal fan in sequence from top to bottom; the external housing of the three-phase motor (13) is communicated with the inner cavity of the shell body (2); a dry brush (9), a wet brush (27), a suction roll (32) and a squeeze roll (44) are installed in the shell body in sequence from front to rear. The wall-cleaning robot of the invention has the advantages of good wall absorption effect, better obstacle-crossing capacity and simple structure and can be remotely controlled.

Description

technical field [0001] The invention relates to a wall surface cleaning robot, in particular to a wall surface cleaning robot based on the principle of positive and negative pressure adsorption. Background technique [0002] With the development of urban construction, more and more high-rise buildings stand in the middle of modern cities. For the sake of beauty and lighting, the wall contours of many high-rise buildings are curved or complex shapes. Many high-rise buildings have adopted this kind of wall surface, which has just brought the cleaning problem of wall surface. Wall cleaning of tall buildings is a heavy and dangerous job. And for indoor wall surface, the problem of efficient cleaning is also paid more and more attention to by people. In this way, the wall cleaning robot came into being. [0003] Traditional wall cleaning robots use negative pressure, vacuum and magnetic adsorption methods. The patent application number is 200510027326.4, the publication numb...
