Abstract

A dust-collectable mobile robotic vacuum cleaner includes a base frame, a driving device mounted to the base frame, a control device mounted to the base frame and electrically connected with the driving device, a collision-detectable unit mounted to the base frame electrically connected with the control device, and a dust-collecting device mounted to the base frame. The dust-collecting device has dust-collecting box, a dust guider, a round brush, and a dust entrance formed at one side of the dust-collecting box. The dust guider is located at a lower edge of the dust entrance, having two opposite sides pivotably mounted to the dust-collecting box and lying against the ground at a predetermined angle respectively, for upward and downward pivoting movement. The round brush is rotatably located at a front end of the dust guider for sweeping dust particles.

Claims

1. A dust-collectable mobile robotic vacuum cleaner comprising:

a base frame;

a driving device mounted to said base frame for generating driving power;

a control device mounted to said base frame and electrically connected with said driving device for controlling said driving device and the moving direction of said base frame

a collision-detectable unit mounted to said base frame and electrically connected with said control device for generating a signal while said base frame in motion encounters a barrier; and

a dust-collecting device mounted to said base frame for collecting dust particles on the ground and having a dust-collecting box, a dust guider, and a round brush, said dust-collecting box having a dust entrance formed at a side thereof, said dust guider having two opposite sides, one of which is pivotably mounted to said dust-collecting box and located at a lower edge of said dust entrance and the other of which extends downward at a predetermined angle to lie against the ground, whereby said dust guider is pivotable on where said dust guider is pivotably mounted to said dust-collecting box to guide the dust particles into said dust entrance, said round brush being rotatably mounted to a front end of said dust guider for sweep the dust particles.

2. The dust-collectable mobile robotic vacuum cleaner as defined in claim 1, wherein said dust guider further comprises two bevels extending slopingly upward from bilateral edges of a bottom section of the dust-collecting plate respectively.

3. The dust-collectable mobile robotic vacuum cleaner as defined in claim 1, wherein said dust guider further comprises at least one guiding portion located at a front end thereof for enabling said dust guider to pivot upward and downward to move across the barrier while encountering the barrier.

4. The dust-collectable mobile robotic vacuum cleaner as defined in claim 1, wherein said dust-collecting device further comprises a side brush mounted to a side of said base frame for horizontally rotatably sweeping the dust particles toward said round brush.

5. The dust-collectable mobile robotic vacuum cleaner as defined in claim 1 or 6, wherein said dust-collecting device further comprises a motor for driving rotation of said round brush or said side brush.

6. The dust-collectable mobile robotic vacuum cleaner as defined in claim 1, wherein said dust-collecting device further comprises an exhaust blower fixed outside said dust-collecting box and a pumping port formed at the other side of said dust-collecting box, said exhaust blower corresponding to said pumping port for pumping the air out of said dust-collecting box and generating negative pressure inside said dust-collecting box.

7. The dust-collectable mobile robotic vacuum cleaner as defined in claim 8, wherein said dust-collecting device further comprises a ventilative dust-collecting plate mounted to said dust-collecting box and located at said pumping port for blocking the dust particles.
