Description:
BACKGROUND OF THE INVENTION  
       [0001]     (a) Technical Field of the Invention  
         [0002]     The present invention relates to an improved structure of a juice blender. An inner cup is provided within the cup body of the juice blender and accordingly the blender can be used for blending of dry and wet foods.  
         [0003]     (b) Description of the Prior Art  
         [0004]     The conventional juice blender comprises a base seat  11 , a motor  12 , a cup body  13 , a covering body  14 , which is shown in  FIG. 1 . In operation, an appropriate amount of water is added into the cup body via an opening at the upper end of the juice blender  1 . The power switch of the juice blender  1  is turned on and the speed of the blender  1  is selected via a speed selector provided on the blender  1 . The motor  12  which drives the blender  1  will not be damaged as the load of wet food stuff will not exceed its maximum load of the motor. However, when the blender  1  is used to blend dry food stuff, the resistance of the dry food stuff is higher and this will cause excessive load to the motor  12 . The motor  12  may not be able to function normally and the motor  12  may be damaged if it is operated for an extended time.  
         [0005]     In order to overcome the above problem, a smaller capacity cup body  13   a  is exploited so as to reduce the load of the motor  12 . This will cause an increase of cost to provide a cup for blending of dry food. Accordingly, it is an object of the present invention to provide an improved structure of a juice blender which has only one cup for dry and wet food blending, and thus, the cost of manufacturing the blender is greatly reduced.  
       SUMMARY OF THE INVENTION  
       [0006]     Accordingly, it is an object of the present invention is to provide a juice blender including a base seat mounted with a motor, a cup body disposed with a blade, an inner cup and a cup cover, characterized in that the upper portion of the inner cup is a funnel shape and the bottom portion of the inner cup is a circular container with an upper portion mounted with a securing rim, the outer end of the securing rim is provided with a plurality of recesses corresponding to protruded ribs within the cup body, the engagement of the recesses with the ribs stabilizes the inner cup within the cup body and the circular container portion of the inner cup defines the capacity of the cup and the effective capacity reduces the load of the motor of the juice blender.  
         [0007]     Yet another object of the present invention is to provide a juice blender, wherein the inner side of the circular tank portion of the inner cup is provided with a plurality of protruded ribs.  
         [0008]     The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0015]     The following descriptions are of 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.  
         [0016]     Referring to FIGS.  3  to  5 , there is shown a juice blender  2  comprising a base seat  21 , a motor  22 , a cup body  23 , an inner cup  24 , a blade  25  and a cup cover  26 .  
         [0017]     The base seat  21  is mounted with a motor  22  having an output shaft  221  passed through the upper end portion of the base seat  21 . The end head portion of the output shaft  221  is mounted with a reamer  222 . On one face of the base seat  21  is provided with a control switch module  211  having ON/OFF and speed selection. The upper end of the base seat  21  is provided with a seat platform  212  to hold the cup body  23 .  
         [0018]     The upper end of the cup body  23  is an open end container body. The bottom portion is disposed with a blade  25 . The axle  251  of the blade  25  is extended to the external side of the cup body  23 , and the axle  251  end is provided with a reamer  252  corresponding to the reamer  222  extended from the motor  22 . The rotation of the blade  25  is driven by the motor via the reamers  252 ,  222 . The bottom of the cup body  23  and the seat platform  212  of the seat base  21  are corresponding to each other. This will allow the cut to firmly place on the base seat  21 . The circumferential edge of the cup body  23  is provided with a plurality of ribs  231  to block food while food stuff is minced by the blade  25 . A handle  232  is provided to one side of the cup body  23  allowing the withdrawal of the cup.  
         [0019]     The inner cup  24  is a through container body having an upper end being a funnel shape mechanism  241 . The lower end portion is a tapered circular container portion  242 . The upper end is extended to form securing rim bodies  243  having a bottom end provided with a plurality of recesses  2431 , corresponding to the protruded ribs  231  of the cup body  23 . The engagement of the recesses  2431  and the ribs  231  can stable the cup body  23 , and circular tank portion  242  at the bottom portion of the inner cup  24  defines a cavity which is the effective capacity of the cup. The inner portion of the circular tank portion  242  is provided with a plurality of ribs  2421 . The ribs  2421  blocks the food stuff and allows effective mincing of the stuff. The height of the inner cup  24  is lower than the cup body  23 . This will facilitate the covering by a cup cover  26 .  
         [0020]     The cup cover  26  has a shape similar to the opening of the cup body  23 . When the juice blender  2  is in operation, the blended food stuff is prevented from coming out from the opening of the cup body.  
         [0021]     When the blender of the present invention is used to blend dry stuff, the inner cup  24  is placed into the cup body  23 . The recesses  2431  of the rim bodies  243  engages with the protruded ribs  231  of the cup body  23  so as to stable the inner cup  24  at the cup body  23 . Dry food stuff is placed through the funnel shape mechanism  241 . The cup body is cover with the cup cover  26 . The lower end of the cup cover  26  can press the upper end edge of the funnel mechanism  241 . This will further stable the cup body  23 . The circular tank portion  242  of the inner cup  24  defines the capacity, which is the capacity of the blended dry food stuff. This capacity is lower than the capacity of the original cup body  23 . When dry food stuff is blended, the load of the motor  22  will not be increased, and this will not cause damage to a motor  22 .  
         [0022]     The blender of the present invention provides an inner cup  24  within the cup body  23  which allows dry and wet blending of food stuff. Thus, the cost of manufacturing of the blender is greatly reduced.  
         [0023]     While the invention has been described with respect to preferred embodiments, it will be clear to those skilled in the art that modifications and improvements may be made to the invention without departing from the spirit and scope of the invention. Therefore, the invention is not to be limited by the specific illustrative embodiment, but only by the scope of the appended claims.  
         [0024]     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.  
         [0025]     While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, 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 spirit of the present invention.
