Document Type and Number:
WIPO Patent Application WO/2023/221906
Kind Code:
A1
Abstract:
A robot cleaner, which relates to the technical field of cleaning devices. The robot cleaner comprises a machine body (10) and an elastic hose (20). A liquid flow channel is formed in the elastic hose (20). An on-off component (30) is arranged on one side of the elastic hose (20), and the on-off component (30) may be moved between a closed position and an open position, and is used for controlling the elastic hose (20) to turn on and off. A cleaning assembly (40) is pivotally connected at the bottom of the machine body (10), such that the cleaning assembly (40) can move between a raised position close to the machine body (10) and a lowered position distant from the machine body (10). A driving device (50) is used for driving the on-off component (30) and the cleaning assembly (40) to move. The robot cleaner drives the on-off component (30) and the cleaning assembly (40) by means of the driving device (50) to move, so that the number of parts that must be mounted in a cleaning device is reduced. Therefore, the size of a mounting space required by the machine body (10) is reduced, a cleaning range that can be covered by the cleaning device is increased, and the overall weight of the device is reduced, thereby reducing the burden of a power system of the robot cleaner, saving energy, and improving the endurance capabilities of the device.
