Dust collection guide structure, dust collection mechanism and sweeping robot

A dust collection guide structure arranged at a bottom of a shell of a dust collection mechanism, comprising an air duct suction opening formed in the bottom of the shell, at least two grooves formed in a surface of the bottom of the shell and at least two sweeping brushes independently arranged at the bottom of the shell and separated from the air duct suction opening, each of the at least two grooves is communicated with the air duct suction opening to form a dust guide air duct for guiding dust into the air duct suction opening, and the at least two sweeping brushes is matched with the at least two grooves so as to facilitate guiding raised dust into the air duct suction opening through the at least two grooves;

• the at least two grooves formed in the surface of the bottom of the shell comprise a first groove and a second groove which are formed in two sides of the air duct suction opening respectively, and the at least two sweeping brushes arranged at the bottom of the shell comprise a first sweeping brush and a second sweeping brush which are arranged in front of the first groove and the second groove respectively;
• wherein the first sweeping brush is disposed parallel to the first groove and the second sweeping brush is disposed parallel to the second groove;
• the first groove and the second groove are integrally formed into a straight line, a splayed shape, or an inverted splayed shape.
