2. Description of the Related Art A double squeegee type floor cleaning machine having a sewage suction port (squeegee) provided before and after a rotary brush for cleaning a floor is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 2-17019.
As disclosed in Japanese Utility Model Laid-Open Publication No. 6-7645 and the like, rubber blades provided on the front and rear squeegees in accordance with the forward or backward movement of the floor cleaning machine are provided with friction resistance against the floor. The opening and closing between the rubber blade and the solid blade is achieved by the reverse bending, whereby the suction and cutoff of the front and rear squeegees are alternately switched.

[0004] Since the rubber blade itself for collecting sewage is a switching valve, if the rubber itself is abused due to long-term use, the elasticity such as flexibility and reversibility can be sufficiently maintained. As a result, the valve function is deteriorated due to the deterioration, and the switching between the suction and the cutoff is hindered. When dust or the like is caught between the rubber blade and the solid blade, the valve function is stopped, and streaks are left on the cleaned floor surface due to the caught dust and the like. Since the rubber blades on both the suction side and the side blocking the suction are always in contact with the floor, the resistance increases the operation of the floor cleaning machine.

Accordingly, a technical problem of the present invention is that the supply and cutoff of suction air to a sewage suction port provided before and after a rotary brush are automatically and alternately performed by using a dedicated switching valve without inverting and bending a rubber blade. It is to switch.
