Abstract

Used in a mobile robotic vacuum cleaner, a dust collector is disclosed to include a dust collection box, and a chips collection box connected to the dust collection box. The chips collection box comprises two openings respectively disposed adjacent to one respective roller brush of the mobile robotic vacuum cleaner and adapted for receiving chips directed by the roller brush for enabling the directed chips to be gathered in the chips collection box. Thus, dust sucked by the mobile robotic vacuum cleaner and chips directed by the roller brushes are respectively collected in the dust collection box and the chips collection box, and any non-dust articles that are accidentally directed into the chips collection box can be discovered and cleaned easily by the user.

Claims

1. A dust collector used in a mobile robotic vacuum cleaner, comprising:

a dust collection box; and

a chips collection box connected to said dust collection box, said chips collection box comprising at least one opening disposed adjacent to one respective roller brush of said mobile robotic vacuum cleaner and adapted for receiving chips directed by said roller brush for enabling said chips to be gathered in said chips collection box.

2. The dust collector as claimed in claim 1, wherein said chips collection box is vertically and linearly movably connected to said dust collection box, and an elastic member is connected between said chips collection box and said dust collection box.

3. The dust collector as claimed in claim 2, wherein said chips collection box comprises a front fillet surface located on a front side of a bottom wall thereof and a rear fillet surface located on a rear side of said bottom wall opposite to said front fillet surface.

4. The dust collector as claimed in claim 1, wherein said chips collection box comprises at least one guide face downwardly extending from said at least one opening.

5. The dust collector as claimed in claim 4, wherein each said guide face of said chips collection box is arch-shaped.

6. The dust collector as claimed in claim 2, wherein said chips collection box comprises a bottom panel, a front panel, a back panel disposed at a front side of said dust collection box, a front fillet surface defined between said front panel and said bottom panel, a rear fillet surface defined between said back panel and said bottom panel, two openings respectively disposed at left and right sides of said chips collection box, and two arched guide faces respectively disposed between said two openings and said bottom panel.

7. The dust collector as claimed in claim 6, wherein said dust collection box comprises a downward-facing plane located on an outer wall thereof and a locating post downwardly extended from said downward-facing plane;

said chips collection box comprises a positioning sleeve located on an outside wall of said back panel and sleeved onto said locating post;

said elastic member is mounted around said locating post and stopped between said dust collection box and said sleeve.
