Title: Health promoting insole

Description:
BACKGROUND OF THE INVENTION 
     The present invention is related to a health-promoting insole, including an upper layer with hollow support rings densely arranged thereon, a bottom layer, and bamboo charcoal powder added at the upper and bottom layers therein respectively wherein the upper and bottom layers are mutually bound together via fastening agent and pressed into insoles of various sizes and shoe shapes; whereby, the insole thereof is equipped with strong absorbing and decomposing capabilities as well as anti-bacteria, humid-adjustment, and deodorization effects. 
     A conventional insole for shoes is not equipped with anti-bacteria or strong moisture absorbing and deodorizing capabilities. Though designed with an airy effect, the conventional insole is unable to adjust humidity and defeat bugs. Once shoes are taken off after a long time of wearing, the conventional insoles therein easily disperse a bad smell of feet. Therefore, such a conventional insole for shoes, which is rather poor in deodorization, is significantly reduced in the quality thereof. 
     SUMMARY OF THE PRESENT INVENTION 
     It is, therefore, the primary purpose of the present invention to provide a health-promoting insole, including an upper layer and a bottom layer with bamboo charcoal powder added therein respectively; whereby, via the bamboo charcoal powder added therein, the insole thereof is equipped with strong moisture absorbing capabilities as well as anti-bacteria, humid-adjustment, and deodorization effects. 
     It is, therefore, the second purpose of the present invention to provide a health-promoting insole wherein hollow support rings are densely arranged at the surface of the upper layer thereon to sustain the weight of sole pressed downwards onto the insole thereof and to generate a massage and airy effect thereby.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to  FIG. 1  showing a perspective flow graph of the present invention (accompanied by  FIG. 2  showing a flow chart of the present invention). The present invention is related to a health-promoting insole that is, in a preferred embodiment, is processed in the steps as follows;
     A. Bamboo charcoal powder  11  in a percentage of 5% is mixed with 95% of filament fibers  12  (especially oxford single filament) before the mixture thereof is closely knitted and drawn into an upper layer  10  with a plurality of hollow support rings  101  densely arranged at the upper surface thereon as shown in  FIG. 5 .   B. Bamboo vinegar liquid  21  and bamboo charcoal powder  22  in a ratio of 1 to 2 are mixed up and heated to dry in 48 hours.   C. Foaming material  23  (especially EVA or PU foaming material) in a percentage of 5 to 10% is added into the mixture of bamboo vinegar liquid  21  and bamboo charcoal powder  22  after heated to dry in 48 hours to be further processed into a bottom layer  20  of a proper thickness.   D. The upper and bottom layers  10 ,  20  with fastening agent applied onto the corresponding surfaces thereon are mutually bound together before pressed into insoles of various sizes and shoe shapes as shown in  FIG. 3 . When the finished insole thereof is located into the interior of shoes  30 , the hollow support rings  101  of the upper layer  10  are able to sustain the weight of a sole A pressed downwards onto the insole thereof, generating a massage and airy effect as shown in  FIG. 4 . Via the bamboo charcoal powder  11 ,  22  added at the upper and bottom layers  10  therein  20 , the insole thereof is equipped with strong absorbing capabilities as well as anti-bacteria, humid-adjustment, and deodorization effects.
