Self-moving cleaning device

A self-moving cleaning device, comprising:

• a base;
• a mobile module adjacent to the base and configured to contact a surface when the self-moving cleaning device moves on the surface;
• a vacuum module arranged over the base;
• a dust box arranged over the base and connected to the vacuum module, the dust box comprising a first opening and a second opening, wherein the first opening is oriented in a first direction different from a second direction in which the second opening is oriented;
• a first suction port arranged on the base and comprising a first suction inlet connected to the first opening, wherein the first suction port is free of any bristle or brush blade;
• a second suction port arranged on the base and comprising a second suction inlet connected to the second opening, the first suction port disposed between a front side of the base and the second suction port;
• a roller brush device arranged on the base and within the second suction port;
• and
• an air duct, wherein the first suction port is connected to the dust box through the air duct to thereby connect the first suction inlet to the first opening,
• wherein
• the first opening is disposed over the roller brush device, and the first opening is disposed over the second opening;
• wherein the dust box comprises:
• a front side wall;
• a bottom surface;
• and
• an inclined surface between the front side wall and the bottom surface, wherein the second opening is arranged on the inclined surface;
• wherein a first included angle is formed between the first opening and the bottom surface, and a second included angle is formed between the second opening and the bottom surface of the dust box, wherein the first included angle is greater than the second included angle;
• wherein the air duct extends, conformal to a shape of a sidewall of the second suction port of the base, from the first suction port to a location over the roller brush device, thereby connecting the air duct to the dust box,
• wherein a shape of the inclined surface corresponds to a wall of the air duct and conforms to the shape of the sidewall of the second suction port, and the dust box and the second suction port are arrangement in a compact manner.
