This application claims priority to Chinese Patent Application No. 202310742770.2, filed on Jun. 21, 2023, the contents of which are hereby incorporated by reference.
The disclosure relates to the technical field of environmental cleaning equipment, in particular to an integrated device for sweeping, mopping and cleaning.
A mopping device adopts two types of mopping methods: active and passive. A passive mopping device fixedly installs a rag at a bottom end of a robot to ensure an effective contact with the floor. When the robot moves forward, the rag is driven to passively wipe the floor and perform a dust pushing action. Because a water output is controlled in advance, there is not much water left on the floor after wiping, so it is no need to collect the remaining water. This method is simple to implement, but a cleaning effect is not good, and the rag is easy to get dirty. In order to maintain the cleaning effect, it is necessary to replace the rag manually and frequently.
Corresponding to passive mopping, active mopping is to install the rag on movable parts of the robot, such as a crawling mechanism and a rotating mechanism, and drive the rag to move relative to the floor actively through motor movements to simulate a reciprocating wiping process when a person is mopping the floor. This method has a better cleaning effect, but more driving parts are needed and a structure is more complicated.
In order to pursue the efficiency and simplicity of cleaning, some active mopping devices increase a water consumption on a basis of active mopping, and then use a suction motor and a suction tray to recover the sewage. This method is common in washing machines in major shopping malls. When the robot moves forward, it pours clean water on the floor, and then a disk brush moves to clean the floor. After cleaning, residual sewage on the floor is sucked up by a circular suction tray at a back of the robot and collected into a sewage tank. This cleaning method has a good effect, but the structure is large. Moreover, because of friction between the suction tray and the floor, the suction tray is easy to damage and leak water after a period of use, resulting in more sewage remaining on the floor, which reduces the cleaning effect.
In order to solve the above problems, the disclosure provides an integrated device for sweeping, mopping and cleaning.
In order to achieve the above objectives, the disclosure is realized by a following technical scheme.
An integrated device for sweeping, mopping and cleaning includes a sweeping structure and an automatic mopping and cleaning mechanism installed on an automatic cruise cleaning robotic vehicle.

The disclosure has advantages as follows. The sweeping structure is located in front of the automatic mopping and cleaning mechanism for sweeping first and then mopping and cleaning, so a cleaning mode is effective. The wet mopping rollers are located in front of the dry mopping rollers, and the automatic cleaning structure for the mopping roller is arranged for cleaning the rollers, that is, the rollers after mopping the floor are cleaned, and the cleaned rollers are used to mop the floor. Wet mopping first and then dry mopping, a suction tray rubbing against the floor does not need to be used, no sewage residue on the floor is realized, and the rollers mopping the floor are often cleaned, so that the floor cleaning effect is better.
