Abstract: A dusting cloth structure for use with a duster includes a sleeve body whose outer surface is provided with a pile layer or a cloth strip layer and which has a receiving groove therein for receiving an external duster shank. One end of the sleeve body is formed with a sleeve opening. A portion of the sleeve body that is away from the sleeve opening is formed with a dividing portion extending toward the sleeve opening. The dividing portion defines two end grooves in the sleeve body, wherein the end grooves are divided from each other and communicate with the receiving groove. Moreover, the inner wall of the receiving groove is formed with a joint accommodating groove along the vertical direction of the surface of the sleeve body to prevent the sleeve body from coming off the shank.

Abstract: A structure for automatically rotating a spiral rod is provided. The structure allows a dusting cloth to be turned into a spiral shape along the spiral rod by rotating a rotating element, and, while the rotating element is being rotated, a torsion spring generates a restoring torque. Once the rotating element is no longer rotated, a pulling element pressing against the teeth inside the rotating element retains the rotating element and thus keeps the dusting cloth in the spiral shape. When the pulling element is subsequently pulled away from the teeth of the rotating element, the rotating element automatically rotates in the reverse direction due to the restoring torque of the torsion spring.

Abstract: A 3D dusting sheet comprising a base sheet, an electrostatic dusting sheet on the base sheet, and one or more linings disposed between the base sheet and the electrostatic dusting sheet, wherein the one or more linings bulge partially a main body of the electrostatic dusting sheet, such that a surface of the 3D dusting sheet becomes three-dimensional. Meanwhile, one or more three-dimensional spaces are formed on the surface of the 3D dusting sheet, whereby a large amount of dirt is gathered in the one or more three-dimensional spaces, and the effect of scraping and collecting the dust or dirt at the same time may be achieved by the 3D dusting sheet during cleaning.
