Description

Floor brush module for cleaning machine and cleaning machine

Technical Field

The utility model relates to the field of household cleaning tools, in particular to a floor brush module for a cleaning machine and the cleaning machine.

Background

A cleaning machine is a relatively common household portable cleaning device, which is originally in the form of a dust collector and can only be used in a dry environment, and in order to meet the use requirements in more environments, products such as a floor cleaning machine and the like are developed especially for coping with wet environments. Most of the existing floor washing machines adopt a front-mounted rolling brush structure, and the rolling brush capable of rotating relative to the machine shell is arranged on the front side of the machine shell, so that the area covered by the rolling brush in rotation can be cleaned by sweeping, the floor washing machine is quite convenient, and when the floor washing machine runs in a wet environment, the water scraping strips arranged front and back of the rolling brush can play a good role in scraping water, and water stain residues are avoided.

The existing wiper strip mostly adopts a fixed connection mode, the setting angle of the wiper strip cannot be changed, so that although the wiper can be realized, the wiper strip can prevent larger particles or hairs from being collected when the floor brush module advances, so that a part of sundries and dust are always free outside a shell of the floor brush module, and the floor brush module needs to be cleaned manually and independently, so that the floor brush module is quite inconvenient.

Therefore, the chinese patent No. CN201520816165.6 discloses a floor brush and a dust collector thereof, in which a front side is provided with a rotatable scraping bar, but since the scraping bar has no external driving power, the scraping bar can only overturn with the friction force generated by the floor when the floor brush module advances or retreats, the overturning form is very dependent on the flatness of the floor, after long-term use, not only many conditions can cause failure of opening the scraping bar, hardening of the scraping bar and reduction of the precision of the overturning mechanism, but also insufficient adhesion degree of the scraping bar and the surface to be cleaned can be possibly caused, thereby causing water leakage and other situations.
