Technical Field

The invention relates to the technical field of sweeping robots, in particular to a self-cleaning sweeping and mopping integrated device and a self-cleaning sweeping and mopping integrated robot.

Background

The current sweeping and mopping integrated robot mainly has two forms:

the 1 st: a fixed water tank and a mop are added into a conventional sweeping robot, and sweeping and mopping are carried out simultaneously. During the moving process of the machine, the swept ground is wiped once by the mop cloth, the water tank continuously drips water on the mop cloth, and the mop cloth is cleaned by hand washing or can be replaced at one time.

The 2 nd: two rotary triangular mops are added into a conventional floor sweeping robot, a cleaning base station is added, the base station is provided with a clean water tank and a sewage tank, and a robot body is not provided with the water tank. The robot cleans the floor in a full house, and then cleans the floor, returns to the base station to clean the mop when working for a certain time, and then returns to the position where cleaning was stopped last time to continue cleaning.

The two traditional sweeping and mopping integrated robots mainly have the following defects:

the 1 st: the mop is wiped once by the robot, and each floor is actually wiped only once. The mops cannot be automatically cleaned, and the mops are increasingly dirty in one cleaning cycle. The volume of the water tank is small, the mop can not be wetted by dropping water, and only the water dropping hole can be wetted better. The mopping efficiency is low and the effect is poor.

The 2 nd: because the modes of sweeping first, then mopping and back-and-forth mopping are adopted, each work needs to manually install a mopping assembly after sweeping is finished; the mopping cycle between the two mop base station washes mops in the mopping process becomes more and more dirty, and the water on the mops becomes less and less. Not only the mopping speed is slow, but also the structure is complex and the cost is higher after the complex base station is added.
