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 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 sweeping and cleaning of the area covered by the rolling brush can be realized, and the floor washing machine is quite convenient. Meanwhile, in order to avoid water stains left on the ground after cleaning in a wet environment, the conventional floor cleaning machine is generally provided with a wiper strip, and the wiper strip is rubbed after contacting the ground by utilizing the driving force when the cleaning machine advances or retreats, so that the wiper strip plays a role in wiping and gathers water into a dust collection cavity so as to be sucked away together with sundries by negative pressure. The existing wiper strip is usually fixed at the bottom of the cleaner housing, and the floor is adapted by utilizing the deformation of the flexibility of the wiper strip, but the form of fixed connection has a certain disadvantage, after the wiper strip is used for a long time, the flexible material of the wiper strip usually has a certain degree of hardening, which leads to water stain residues after the wiper strip is used for a long time, the more serious the hardening degree is, the more water stain residues are, and the inconvenience is caused.

Therefore, a part of cleaning machines with scraping strips solve the water stain problem in a manner of swinging the scraping strips, for example, the Chinese patent application with the patent number of CN201710680218.X discloses a floor brush and a cleaning dust collector thereof, the scraping strips adopt a design form of swinging back and forth integrally, compared with local deformation, the integral swinging of the scraping strips can enlarge the effective use area participating in water scraping, so that the negative influence reduction brought by a hardening part is made up to a certain extent, but the negative influence reduction is not achieved, the decisive effect is not achieved, the residual of water stains after cleaning can not be effectively restrained, particularly, when the cleaning machine is stopped or retreated, the scraping strips are not abutted against the rear side of a shell at the position where the cleaning machine is located, water drops are easy to drip at the gap of the scraping strips, and the water stain residual is caused.
