20140137367 | AUTONOMOUS COVERAGE VACUUM CLEANER HAVING ROLLER BRUSH CAPABLE OF RESILIENT VERTICAL DISPLACEMENT AND ROLLER BRUSH FRAME UNIT FOR THE SAME - Provided are an autonomous coverage vacuum cleaner and a roller brush frame unit for use therewith. The autonomous coverage vacuum cleaner includes a body, the roller brush frame unit, and at least a roller brush. The roller brush frame unit includes a roller brush frame, a connection frame, and a resilient connection element. The connection frame is disposed at a bottom of the body. The resilient connection element is connected between the roller brush frame and the connection frame. The roller brush frame moves vertically relative to the connection frame and the body when subjected to an external force. The roller brush is rotatably disposed at the roller brush frame. The roller brush frame unit enables the roller brush of the autonomous coverage vacuum cleaner to lift and drop resiliently and automatically according to the condition of the floor. | 05-22-2014 |
20140130294 | AUTONOMOUS COVERAGE VACUUM CLEANER HAVING EDGE CLEANING HEAD EASY TO INSTALL AND UNINSTALL - An autonomous coverage vacuum cleaner includes a transmission element driven to rotate and disposed at the bottom of a body, and an edge cleaning head. The transmission element has a lower surface, a positioning recess denting upward from the lower surface and having a non-circular inner profile, and a fixing hole disposed in the positioning recess. The edge cleaning head includes a body, at least a brush extending from the body, a positioning block disposed on the body, and resilient elements extending upward from the positioning block. An outer profile of the positioning block corresponds in shape to the inner profile of the positioning recess. Under an applied force, the resilient elements deform resiliently, get closer to each other, and engage with the fixing holes. The positioning block engages with the positioning recess of the transmission element, such that the transmission elements drive the edge cleaning head to rotate. | 05-15-2014 |
