Abstract:
1. A cleaning device comprising: a frame body having a front surface and a rear surface defining a middle portion and a peripheral portion therebetween, a plurality of engagement ribs distantly formed on a peripheral edge of the peripheral portion, and a plurality of connecting holes provided in the peripheral portion and extended from the front surface through the rear surface, each connecting hole comprising an individual larger diameter cylindrical hole and an individual smaller diameter cylindrical hole coaxially connected with one another, wherein the individual smaller diameter cylindrical holes are separated from one another and are open on the front surface of the frame body, and the individual larger diameter cylindrical holes are separated from one another and are open on the rear surface of the frame body, wherein the middle portion is surrounded by the peripheral portion and indented from both the front and rear surfaces of the frame body, and wherein the peripheral edge of the peripheral portion has a round profile extending from the front surface to the rear surface of the frame body; and a plurality of bundles of cloth mop strips each twisted and folded to define a folding point between free ends of the cloth mop strips, wherein each bundle of cloth mop strips is disposed in a respective connecting hole of said frame body such that each folding point is protruded from the corresponding individual smaller diameter cylindrical hole into the corresponding individual larger diameter cylindrical hole of the respective connecting hole and accommodated within said individual larger diameter cylindrical hole of the respective connecting hole with said free ends extended outwards from said folding point through said smaller diameter cylindrical hole of the respective connecting hole and the front surface of said frame body; wherein an inner side wall of each individual larger diameter cylindrical hole exclusively contacts and compresses the folding point of a corresponding bundle of cloth mop strips to retain the folding point proximate to a corresponding individual smaller diameter cylindrical hole such that said folding point is completely accommodated within said corresponding individual larger diameter cylindrical hole of the respective connecting hole; and wherein the plurality of engagement ribs and the round profile of the peripheral edge of the peripheral portion are adapted for releasable engaging the frame body with a handle of the cleaning device.
