The invention discloses a negative-pressure adsorption foot suitable for a non-horizontal smooth wall surface wall-climbing robot. The negative-pressure adsorption foot is characterized in that a sucking disc is arranged at the lower end of a sucking disc rod; the upper end of a negative-pressure sucking disc rod is connected with a piston; the upper part of the piston is connected with the lower end of a jacking and pressing spring; a sliding cavity which is used for assembling the sucking disc rod, the piston and the jacking and pressing spring is formed in a shell; the upper end of the jacking and pressing spring is in contact with the top wall of the sliding cavity in a jacking way; the piston of the sucking disc rod is assembled in the sliding cavity in a vertical sliding and sealing way; an inner cavity of the sucking disc rod is hollow; a sucking disc rod negative-pressure opening and a sucking disc rod atmosphere opening are formed in the wall surface of the sucking disc rod; a shell negative-pressure opening and a shell atmosphere opening are also formed in the wall surface of the shell; the distance difference of the distance between the sucking disc rod negative-pressure opening and the sucking disc rod atmosphere opening and the distance between the shell negative-pressure opening and the shell atmosphere opening is a displacement stroke of the piston; the shell negative-pressure opening is connected with a negative pressure generating device; an electromagnetic device which is used for driving the piston to move upwards to compress the spring through an electromagnetic principle is arranged in the shell outside the piston. The negative-pressure adsorption foot disclosed by the invention has the advantages that the structure is simplified, elements are fewer, the size is small, and the cost is lower.
