Abstract:
A cleaning apparatus is provided to clean a sophisticated electric device. The apparatus has cleaning units and each of the cleaning units has a cambered top. Thus, coordinated with an actuating device, a sophisticated electric device can be cleaned by using the cleaning apparatus with cleaning units having cambered tops.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to cleaning a sophisticated electric device; more particularly, relates to obtaining a big surface contact area, a fast cleaning velocity and a high decontamination rate on using a cleaning apparatus with cleaning units having cambered tops to clean a surface of a sophisticated electric device with coordination of an actuating device. 
       DESCRIPTION OF THE RELATED ARTS 
       [0002]    A first prior art of a cleaning device is made of elastic polyvinyl alcohol (PVA) sponge with a number of outgrowths on a side surface, where tops of the outgrowths are smooth and the cleaning device is rotated to touch and clean a surface of an electric device with the tops of the outgrowths. Thus, coordinated with an actuating device, the electric device can be cleaned by using the first prior art with the outgrowths. 
         [0003]    A second prior art of a cleaning device comprises a base and a porous material, where the base has an inner surface and an outer surface; the porous material covers at least a part of the outer surface of the base to be combined with the base; the base has a number of protrusions; and the protrusions of the base are set correspondingly to the surface of the porous material. Thus, coordinated with an actuating device, the electric device can be cleaned by using the second prior art with the protrusions. 
         [0004]    The above prior arts can be used to clean the electric device. But, in the first prior art, each outgrowth has a very smooth top and the top is flat; and, in the second prior art, each protrusion also has a flat top. These prior arts do not effectively touch and clean the electric device which may have an unsmooth surface. Hence, the prior arts do not fulfill all users&#39; requests on actual use. 
       SUMMARY OF THE INVENTION 
       [0005]    The main purpose of the present invention is to obtain a big surface contact area, a fast cleaning velocity and a high decontamination rate on using a cleaning apparatus with cleaning units having cambered tops to clean a surface of a sophisticated electric device with coordination of an actuating device. 
         [0006]    To achieve the above purpose, the present invention is a cleaning apparatus for a sophisticated electric device, comprising a carrier, and a plurality of cleaning units, where the plurality of cleaning units is deposed on a surface of the carrier; each of the cleaning units has a cambered top on an end surface; and the cambered top has a curve ratio between 70 percents (%) and 99%. Accordingly, a novel cleaning apparatus for a sophisticated electric device is obtained.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0013]    The following descriptions of the preferred embodiments are provided to understand the features and the structures of the present invention. 
         [0014]    Please refer to  FIG. 1  and  FIG. 2 , which are a perspective view and a sectional view showing a first preferred embodiment according to the present invention. As shown in the figures, the present invention is a cleaning apparatus for a sophisticated electric device, comprising a carrier  1  and a plurality of cleaning units  2 , where the carrier  1  and the plurality of cleaning units  2  are made into a whole one and are made of a composite material, sponge, polyurethane (PU), polyvinyl alcohol (PVA) or a polymer material. 
         [0015]    The carrier  1  is a circular column and has a sheathing part  11  within at center. 
         [0016]    The plurality of cleaning units  2  is deposed on an outside surface of the carrier  1 , where the cleaning units  2  are circular columns or polygon columns; each of the cleaning units  2  has a cambered top  21  on an end surface; and the cambered top  21  has a curve ratio between 70 percents (%) and 99%. 
         [0017]    Please refer to  FIG. 3 , which is a view showing a state of use of the first preferred embodiment. As shown in the figure, on using the first preferred embodiment, an actuating device  3  is combined with a carrier  1  or a plurality of carriers  1  through each sheathing part  11  of the carrier  1 . The actuating device  3  rolls the carrier  1  to move to a position for cleaning a sophisticated electric device  4 , where each of the cleaning units  2  of the carrier  1  has a cambered top  21 ; and the cleaning units  2  are contacted with a surface of the sophisticated electric device  4  for required cleaning. Because the cambered top  21  has a curve ratio between 70% and 90%, the cleaning units  2  obtain a big surface contact area, a fast cleaning velocity and a high decontamination rate. 
         [0018]    Please refer to  FIG. 4  and  FIG. 5 , which are a perspective view showing a second preferred embodiment; and a view showing a state of use of the second preferred embodiment. As shown in the figures, a carrier  1  a of a second preferred embodiment is a disk, where a plurality of cleaning units  2  is deposed on a surface of the carrier  1  a; an assembling part  12   a  is set on another surface of the carrier  1   a;  and the cleaning units  2  are circular columns and/or polygon columns. 
         [0019]    On using the second preferred embodiment, an actuating device  3   a  is combined with the carrier  1   a  or a plurality of the carriers  1   a  through each assembling part  12   a  of the carrier  1   a.  The actuating device  3   a  rotates the carrier  1   a  or the plurality of the carriers  1   a  to move to position for cleaning a sophisticated electric device  4 , where the cleaning units  2  of each carrier  1  a are contacted with a surface of the sophisticated electric device  4  for required cleaning. 
         [0020]    To sum up, the present invention is a cleaning apparatus for a sophisticated electric device, where a big contact area, a fast cleaning velocity and a high decontamination rate are obtained by using cleaning units having cambered tops on cleaning a surface of a sophisticated electric device with coordination of an actuating device. 
         [0021]    The preferred embodiments herein disclosed are not intended to unnecessarily limit the scope of the invention. Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
