Background

At present, the products for mopping the floor in the market have two modes, one mode is a manual mop, the other mode is an electric mopping machine, the manual mop realizes the functions of cleaning and spin-drying the mop by driving the mop to rotate by using a hand-pressing mop rod, and the mop cleaning machine is simple and practical, but needs great strength and labor in the whole process. At present, an electric floor mopping machine generally adopts a constant-speed motor and a speed reducer and a reversing device, so as to drive a mop to rotate at a constant speed or reciprocate back and forth, and rub the ground to achieve the effect of cleaning the ground. Such an electric floor-mopping machine reduces the burden of manpower in mopping, but does not well solve the problems of automatic cleaning and spin-drying of the mop cloth. The dirty mop cloth needs to be manually detached for cleaning, and is wrung out or dried for reuse, and the mop cloth needs to be manually replaced and cleaned for several times to clean the floor when the floor is mopped by a common household, which is very inconvenient. In addition, when the floor is mopped, the water is sprayed to wet the floor through the water tank, the dryness and humidity of the floor are not easy to control, if the water is sprayed less, the floor can not be mopped cleanly, if the water is sprayed more, the floor can be very wet, and the mopping effect is not good.

Therefore, there is room for improvement in electric mops that are not capable of automatically cleaning and spin-drying mops.
