An autonomous cleaning device and a cleaning system

Abstract

Autonomous cleaning device, characterized in that the autonomous cleaning device comprises: a housing (100); a side brush module (200), wherein it is arranged on the housing (100) and comprises a side brush drive mechanism and side brushes (210), wherein the side brush drive mechanism serves to rotate the side brushes (210); and a center brush module (300), wherein it is arranged on the bottom of the housing (100) and comprises a brush roller drive mechanism and a brush roller (310), wherein the brush roller (310) is arranged in a vacuum chamber on the bottom of the housing (100) of the autonomous cleaning device and the brush roller drive mechanism serves to rotate the brush roller (310);a wiping module (400) wherein it is arranged in a receiving chamber (110) at the bottom of the housing (100), the wiping module (400) comprising a wiping cloth roller (410) and a wiping cloth drive mechanism for driving the rotation of the wiping cloth roller (410), wherein a water supply mechanism and a dirt removal mechanism are arranged in the direction of rotation of the wiping cloth roller (410);and a wiper module drive mechanism serving to move the wiper module (400) in the vertical direction of the housing (100), wherein the wiper module (400) can be moved between a raised height and a wiping height, wherein the wiper module (400) can come into contact with the surface to be cleaned at the wiping height and breaks contact with the surface to be cleaned at the raised height, and serving to move the wiper module (400) in the lateral direction of the housing (100) of the autonomous cleaning device, wherein the wiper module (400) is movable between a retracted position and an extended position and the wiper module (400) is located further away from the receiving chamber (110) in the extended position than in the retracted position;wherein the autonomous cleaning device has at least one single-sweeping operating state and one sweeping and mopping operating state, wherein in the single-sweeping operating state the mopping module (400) is in the raised height, the wiping cloth roller (410) stops its rotation, the brush roller (310) and / or the side brushes (210) rotate, wherein in the sweeping and mopping operating state the mopping module (400) is in the mopping height and in the retraction or extension position, wherein the wiping cloth roller (410) rotates;wherein the autonomous cleaning device can switch from the single-sweeping operating state to the sweeping and mopping operating state during the work process, wherein the mopping module drive mechanism drives the mopping module (400) to move to the mopping height during the switching process, the mopping cloth drive mechanism drives the mopping cloth roller (410) to move before the mopping module (400) reaches the mopping height, and drives the rotational speed of the mopping cloth roller (410) to a specific range.
