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

The conventional movable cleaning equipment mostly adopts a rolling brush as a sweeping brush executing piece, and brush pieces or brush hair on the periphery of the rolling brush are contacted with a surface to be cleaned through rolling of the rolling brush, so that dirt attached to the surface to be cleaned is cleaned. And in order to ensure the cleaning effect, it is common to provide spouts on the housing and spray the cleaning liquid to the surface of the roll brush.

For example, chinese patent application No. CN202010568160.1 (publication No. CN111820816 a) discloses a "dry and wet sewage tank assembly for a water machine", in which a sewage inlet pipe is disposed at the bottom of the sewage tank, the filter assembly is disposed inside the sewage tank and is sleeved on the sewage inlet pipe, the tank cover assembly is mounted on the sewage tank, the mixed fluid remains in the sewage tank after passing through the sewage tank, the air flow continues to flow to the downstream negative pressure source, an air outlet is opened at the end of the air path of the floor washing machine, i.e., on the housing of the air machine module in the floor washing machine, and the air flow sucked by the negative pressure is finally discharged from the air outlet. The cleaning machine only depends on a negative pressure source as a main force of dust collection, cannot clean some stubborn stains well, is limited by the rotation form of the rolling brush, and water sprayed on the surface to be cleaned is sucked away by negative pressure after being used for one to two times, so that the cleaning effect is relatively limited.

For this reason, the applicant has made a certain improvement to the conventional rolling brush cleaning mode, and has proposed another cleaning mode, and in chinese application publication No. CN201911094051.4 (publication No. CN 112773255A), an integrated structure for cleaning object surface is disclosed, which is provided with a brush in a dust collection cylinder, the brush being rotatable in an inner axial direction of the dust collection cylinder, i.e., a rotation axis thereof is vertically extended unlike a horizontal arrangement of the conventional rolling brush. The brush arrangement form can enhance the flow field of the central area of the fluid by cleaning the ground with the brush hair when in work, and can reduce the dirt residue in the central area by matching with the cleaning liquid, thereby avoiding the situation that the water cleaning capacity is sucked away by negative pressure after being used for a small number of times in the rolling brush mode, and meeting the requirement of heavy cleaning in a wet environment. However, the cleaning liquid is sourced from the periphery of the brush, namely, is sprayed to the brush or the surface to be cleaned, and the cleaning liquid can be dispersed around along with the centrifugal action of rotation due to the special vertical arrangement of the brush, so that the part being washed is very limited in scouring, and the cleaning liquid still has a good cleaning effect on some stains with great cleaning difficulty.
