Description

Floor washing machine

Technical Field

The utility model relates to the technical field of cleaning equipment, in particular to a floor cleaning machine.

Background

The floor washing machine is a cleaning machine which is suitable for cleaning hard ground and sucking sewage at the same time, and can separate the sewage from the site, has the advantages of environmental protection, energy saving, high efficiency and the like, and comprises a roller assembly for cleaning ground garbage and a cleaning brush assembly for cleaning garbage adhered on the roller assembly.

In the existing floor washing machine products, the water tank is usually arranged on the handle (the parts outside the cleaning head of the floor washing machine are commonly called as the handle), so that the user bears the weight of the whole water tank on the handle when pushing or pulling the floor washing machine by hand, and the user can easily feel arm pain for a long time.

In the existing floor washing machine products, the roller component and the cleaning brush component are driven to work through different motors respectively, when the floor washing machine works, the roller and the brush component work synchronously, the double motors generate larger noise in the working state of synchronous high rotation speed, and meanwhile, the standby time of the floor washing machine is reduced because the double motors work.

In the above prior art, as disclosed in chinese patent CN111150337A, CN113876245A, CN114680747a, the water tanks are all provided on the handle, and users can be tired when pushing or pulling the floor washer by hand. As disclosed in chinese patent CN218009602U, the separate driving motor provides driving force to drive the gear set to rotate so as to drive the brush roller to rotate, and the cleaning roller is driven by another separate driving motor, so that the brush roller and the cleaning roller rotate in opposite directions, which is more beneficial for the brush roller to brush down the viscous garbage on the cleaning roller, but the separate motor for driving the brush roller consumes more electric quantity, and reduces the electric power endurance time of the floor scrubber; the cleaning machine disclosed in the chinese patent CN215605440U drives the whole cleaning machine to work through a driving assembly which drives the roller and the cleaning brush to rotate simultaneously, but the installation structure of the cleaning brush in the scheme is too complex, and the cleaning brush cannot be taken out from the cleaning machine easily to be cleaned thoroughly.

Therefore, the problem of arm ache caused by long-time use of the floor washing machine by a user is solved, and the problem of reducing the noise of the floor washing machine while prolonging the standby time of the floor washing machine is the technical problem to be solved at present.
