SELF-PROPELLED CLEANING DEVICE

摘要

A self-propelled cleaning device includes a chassis with a protrusion, such that a side brush mechanism is proximate to the external periphery of the contour of the chassis, and an elastic element installed between a driving wheel set and the chassis for providing buffer and shock absorption. An interval is formed between the front edge of the chassis and a dust inlet for guiding dust into a dust collecting case in a chassis containing groove, and the containing groove has a first spacer apart from a control unit and a second spacer separating a carrying space from a negative pressure device. The second spacer has a passage interconnecting the containing groove and the carrying space, and the dust collecting case has separated first and second sides. The first side has a negative pressure outlet, and the negative pressure device has a negative pressure guide channel and a negative pressure inlet corresponding to the hollow passage in the second spacer of the chassis containing groove and a negative pressure outlet of the dust collecting case respectively to allow air to flow through.

1. A self-propelled cleaning device, comprising:
a chassis, including a side brush mechanism for executing a cleaning function, a driving wheel set for carrying and moving the chassis, a dust collecting case for collecting dust, a negative pressure device having a vent for discharging air to provide a negative pressure suction, and a control unit for executing a system control; wherein, the chassis has a protrusion protruded and extended from the external periphery of the contour of the chassis, and the side brush mechanism performs a rotational sweeping by a driven bristle, and the protrusion moves the installation position of the side brush mechanism closer to the external periphery of the contour of the chassis.
