DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0019] Referring to FIGS. 1-3, which are respectively a perspective view showing a preferred embodiment of the present invention, a cross-sectional view of the preferred embodiment of the present invention, and another cross-sectional view of the preferred embodiment of the present invention, it can be clearly seen from these drawings that the present invention comprises:

[0020] a disc 1, wherein the disc 1 is configured with a flat section 11 and at least one slope section 12 located on an outer side of the flat section 11;

[0021] at least one coupling section 13 provided on the flat section 11, wherein the coupling section 13 comprises for example a piece of hook-and-loop fastener for coupling with at least one cleansing member 2, wherein the cleansing member 2 is for example a sponge; and

[0022] a coupling member 14 provided on a side of the disc 1 that is distant from the coupling section 13, wherein the coupling member 14 is formed with a through-hole section 141 and the through-hole section 141 is formed with at least one threaded section 142 for coupling with an electric motor 3, wherein the coupling member 14 is formed, on a side thereof that is distant from the through-hole section 141, with at least one fixing section 143.

[0023] Referring to FIGS. 1-4, which are respectively a perspective view showing a preferred embodiment of the present invention, a cross-sectional view of the preferred embodiment of the present invention, another cross-sectional view of the preferred embodiment of the present invention, and a schematic view illustrating an operation of use of the preferred embodiment of the present invention, it can be clearly seen from these drawings that with an attempt to wax or polish an automobile body 4, a user may couple the cleansing member 2 to the coupling section 13 and screw the coupling member 14, by means of the threaded section 142 formed in the through-hole section 141, to the electric motor 3 so as to couple the disc 1 and the electric motor 3 together. The fixing section 143 provided on the coupling member 14 allows the user to apply a wrench to easily couple or remove the coupling member 14 to or from the electric motor 3. Further, the user may attach wax to the cleansing member 2 and then activate the electric motor 3 to allow the electric motor 3 to drive the cleansing member 2 to rotate so that the cleansing member 2 may coat the wax uniformly on the automobile body 4. However, since, during the rotation of the disc 1, the slope section 12 that is spaced from a center of the disc 1 by a distance greater than a distance of a part or the entirety of the flat section 11 from the center the disc 1 provides a torque larger than that provided by the flat section and thus would apply a relatively large operation force to the automobile body 4. Thus, the operation of waxing or polishing for scratching removal of the automobile body 4 can be conducted in a more efficient way by means of the slope section 12. It is more important that the slope section 12 is arranged as being inclined with respect to the flat section 11 and can thus be positioned more closely and tightly on a curved part of the automobile body 4. Further, in use, the inclined arrangement of the slope section 12 allows an outer circumferential edge of the disc 1 not to easily contact the automobile body 4, so that undesired scratching on the automobile body 4 by the edge of the disc 1 can be prevented.

[0024] Further, the disc 1 is integrally formed as a unitary structure and thus possesses the advantages of efficient fabrication and cost saving.

[0025] Referring to FIG. 5, which is a cross-sectional view showing another embodiment of the present invention, it can be clearly seen from the drawing that a disc 1a is configured with a flat section 11a and at least one slope section 12a arranged at an outer side of the flat section 11a and the slope section 12a is provided with at least one coupling section 13a for coupling with a cleansing member 2a. The disc 1a is formed, on a side thereof that is distant from the coupling section 13a, with a coupling member 14a that is formed with a through-hole section 141a comprising a threaded section 142a for coupling the disc 1a to an electric motor. Further, the coupling member 14a is provided with a fixing section 143a that allows a user to use a wrench to easily couple or remove the coupling member 14a to or from the electric motor. A difference of the instant embodiment from the previous embodiment is that the coupling section 13a is provided on the slope section 12a, rather than the flat section 11a so that the cleansing member 2a can be more closely positioned on the slope section 12a to achieve the purpose of preventing a circumferential edge of the disc 1a from scratching the automobile body.

[0026] Referring to FIGS. 6 and 7, which are respectively a cross-sectional view showing a further embodiment of the present invention and a schematic view illustrating an operation of use of said further embodiment of the present invention, it can be clearly seen from the drawings that a disc 1b is configured with a flat section 11b and at least one slope section 12b arranged at an outer side of the flat section 11b, wherein the flat section 11b and the slope section 12b are provided with at least one coupling section 13b. The coupling section 13b is provided for coupling with at least one cleansing member 2b so that a user may use the electric motor 3b to drive a cleansing member 2b that is coupled to the disc 1b to conduct waxing or polishing for scratching removal on an automobile body 4b. A difference of the instant embodiment from the previous embodiments is that the coupling section 13b is provided on both the slope section 12b and the flat section 11b so that the cleansing member 2b can be more closely positioned on both the slope section 12b and the flat section 11b to prevent the cleansing member 2b from easily detaching from the disc 1b during a waxing operation and thus, achieving the purpose of preventing the disc 1b from scratching and damaging the automobile body 4b.

[0027] Reference is now made to all the drawings. The present invention, when put into use, provides the following advantages over the prior art devices:

[0028] (1) The arrangement of the slope section 12 allows for easy and efficient polishing and waxing an automobile body 4 without causing undesired scratching or damage to the automobile body 4.

[0029] (2) The arrangement of the coupling section 13 allows a cleansing member 2, such as sponge, to be coupled to the disc 1.

[0030] (3) The arrangement of the coupling member 14 allows coupling of the disc 1 to an electric motor 3 to be conducted with an effect of being efficient and effort saving.

[0031] (4) The arrangement of the fixing section 143 allows the user to use a wrench to easily couple or remove the coupling member 14 to or from an electric motor 3.

[0032] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

[0033] While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
