Abstract

A squeegee assembly which includes a laterally elongated cover body, one pair of flexible front and rear blades forwardly/backwardly spacedly arranged in parallel relation on the cover body, and a blower for applying a sucking function to an interval between the pair of blades so that a dirty liquid gathered by the one pair of flexible blades is sucked up from a floor surface for collection, wherein a lower side portion of the front side flexible blade is bent horizontally towards the rear side flexible blade thereby to form a contacting surface, a distal end side thereof is raised such that a small opposing space is formed between the rear side flexible blade and the front side flexible blade and secured to the cover body side, thereby defining a suction chamber, on which the sucking force of the blower is prevailed, at a lower side of the cover body, a plurality of concave or wedge-shaped guide grooves are formed in a bottom surface of the horizontally bent contacting surface, and a dirty liquid sucking cavity for intercommunicating the suction chamber and the opposing space is formed in a surface of the raised portion.

Claims

1. A squeegee assembly for a scrubber, said assembly comprising:

(a) an elongated cover body;

(b) a flexible front blade;

(c) a flexible rear blade, said front and rear blades being spacedly arranged in parallel relation on said cover body to define a space between said front and rear blades; and

(d) a blower for applying a sucking function to said space to suck up from within said space a dirty liquid gathered by said front and rear blades from a floor surface,

said front blade having (i) a lower side portion bent horizontally toward said rear blade to form a horizontally bent floor contacting surface and (ii) a distal end side which forms a raised portion to define an opposing space between said rear blade and said raised portion of said front blade, said raised portion being secured to said cover body, said front blade and a lower side of said cover body defining a suction chamber, said sucking function of said blower being applied to said suction chamber, said horizontally bent contacting surface having a bottom surface in which a plurality of guide grooves are formed, and said raised portion having formed therein a dirty liquid sucking cavity for intercommunicating said suction chamber and said opposing space.

2. A squeegee assembly for a scrubber as in claim 1, wherein said cover body has a portion including an air port on which said sucking function of said blower is applied, and said guide grooves are slanted toward a center line of said dirty liquid sucking cavity and include rearward end ports which are in communication with said dirty liquid sucking cavity.
