  The present invention relates to a brush device suitable for use in a floor cleaning machine, a floor cleaning machine, or a floor polishing machine for cleaning, cleaning or polishing various floors such as offices and airport lobbies. Specifically, the present invention relates to a brush device for a floor cleaning machine or the like that is devised so that cleaning and cleaning of a floor surface or polishing can be performed simultaneously with a brush and a pad.

  A conventional general floor cleaning machine uses a motor to rotate a cleaning brush at high speed to remove dirt on the floor with a brush. For example, the floor surface is made of ceramic tiles. If the cleaning brush is cleaned directly with this cleaning brush, the cleaning brush that rotates at a high speed cannot clean the pores formed on the surface of the ceramic tile. There was a problem that could not be washed.

  In other words, ceramic tiles have many fine holes in the surface where the air has escaped during firing, and the dust accumulated in these pores left the tile surface dark and dirty. In the conventional general floor cleaning machine that rotates the cleaning brush at a high speed, there is a problem that the dust in the pores cannot be cleaned cleanly, leaving dirt.

  Therefore, as a cleaning means for ceramic tiles, for example, “Polisher” described in Patent Document 1 and “Pad for Floor Cleaning Machine” described in Patent Document 2 have been developed. That is, the “Polisher” of Patent Document 1 is configured so that dirt on the ceramic tile can be cleaned only with water without using a detergent by fixing a melamine-based resin foam to the tip of the pad base that is rotationally driven. Has been.

Further, in claim 1 of Patent Document 2, there is a description of a doughnut-shaped melamine foam floor cleaning machine pad for removing dirt that has entered the pores of the ceramic tile. In the case of a floor cleaning machine, a foam support plate supported by an elastic member is installed at the center of the pad base, a donut-shaped melamine foam is attached to the foam support plate, and a brush is annularly arranged outside the foam support plate. The pad is described.
