Double-roller floor washing robot and floor washing method thereof

Abstract

The invention discloses a double-roller floor washing robot and a floor washing method thereof. The double-roller floor washing robot comprises a robot body, wherein the robot body is provided with acleaning device; the cleaning device comprises a roller assembly and a water circulation system; the roller assembly comprises a first roller, a second roller and a roller driving device; the rotatingdirection of the first roller is consistent with the advancing or retreating direction of the double-roller floor washing robot, and the rotating direction of the second roller is opposite to the rotating direction of the first roller; and a water circulation system comprises a purified water tank, a roller gearbox, a sewage tank and a fan; the first roller and the second roller are located in the roller gearbox, the roller gearbox is provided with a water flow channel which has a plurality of water outlet holes, the purified water tank is communicated with the water flow channel, the rollergearbox is communicated with the sewage tank, the sewage tank is communicated with the fan, and the fan is communicated with an air outlet. The double-roller floor washing robot has the advantages that the rollers is cleaned while a floor is cleaned, the floor can be mopped while the floor is swept, and double-roller floor washing robot is simpler in structure, smaller in overall size and more convenient to use.

Problems solved by technology

[0003] Although this kind of sweeping robot also has a mopping roller, it has the following defects in the cleaning process: first, after cleaning the ground, the rag on the roller needs to be manually disassembled for cleaning, and disassembly and cleaning are not only cumbersome to operate , and the user needs to stop the operation, which brings great inconvenience to the user; second, when using the sweeper with this structure, it needs two steps to clean up the garbage and mop the floor, that is, to clean up the garbage It is carried out by using the structure of cleaning, and mopping the floor is carried out by the structure of the mopping roller. At present, all the sweepers on the market have this problem, that is, a single mopping roller cannot perform the functions of cleaning garbage and mopping the floor. In this way, the whole machine The larger the volume, the higher the cost
