Description

Cleaning device, floor washing machine and floor sweeping machine

Technical Field

The utility model relates to the technical field of automatic cleaning, in particular to a cleaning device, a floor washing machine and a floor sweeping machine.

Background

The bottom of automatic cleaning equipment such as floor cleaning machines, mopping machines, floor wiping machines and some floor sweeping machines in the existing market is provided with the rag, the rag be used for wet mopping ground, the rag on most of automatic equipment all can become dirty and can not obtain timely clearance after cleaning ground, along with automatic equipment's operation, dirty rag continues wet mopping ground, then the dust on the rag can be left subaerial along with sewage together, makes and leaves the trace on the ground, and ground is still very dirty, and cleaning performance is not good.

In order to solve the problem of dirt in the rag, some research is done in the industry:

for example, in some of the caterpillar type cleaning cloths, as described in chinese patent CN201510054983.1, the cleaning cloth advances in caterpillar type during wet mopping, when the cleaning cloth rotates to contact with the ground, the cleaning cloth is wiped by a special cleaning cloth cleaning component after the cleaning cloth rotates to be out of contact with the ground, which seems to solve the self-cleaning problem of the cleaning cloth. Because the crawler-type cleaning cloth can be separated from the surface to be cleaned only by a certain walking length, the contact length of any point on the crawler-type cleaning cloth with the ground is long, the dust is more, and the cleaning cloth cannot be cleaned before the point leaves the ground, so that when the point leaves the ground, solid dirt such as sewage, dust and the like on the cleaning cloth easily falls on the ground again due to gravity, the ground cannot be cleaned, and the cleaning capability of the crawler-type cleaning cloth is not as good as that of a reciprocating cleaning cloth or a rotating disc type cleaning cloth.

For another example, in the case of providing a cleaning base station, as disclosed in chinese patent CN201210543651.6, the used cleaning cloth needs to return to the base station, the cleaning mechanism on the base station cleans the cleaning cloth, and then the cleaning cloth runs back to the work stop point to continue working, so that the cleaning cloth can be thoroughly cleaned. However, the cleaning cloth still cannot be cleaned in time after being used for mopping the floor, the dirty cleaning cloth still leaves marks on the floor after being used for mopping the floor, and if the time interval for returning the cleaning cloth to the base station for cleaning is shortened to improve the floor cleaning effect, the working efficiency of the host machine is greatly reduced.

The applicant is a deep plougher in the field of cleaning products, and has no good way to solve the problems, so that long-term intensive research is carried out, a large amount of time and energy are invested, and the thought limitation can be expected to appear, so that a new technical scheme is provided to solve the problems, the cleaning cloth can be cleaned in time on the premise of not influencing the working efficiency of a host, and meanwhile, the dirt generated by cleaning can be treated in time.
