Stirring device for increasing capacity of trash bin

Abstract

This invention discloses a stirring device for increasing the capacity of a trash bin. The lower portion of the trash bin has a stirring device that can stir shredded paper. The stirring device includes an actuator and a comoving element. The actuator is pivotally connected with the trash bin, with the pivotal point as the connecting position. The comoving element is fixed on the actuator and moves synchronously with it. When a force is imposed on the actuator, the comoving element performs a reciprocal motion using the pivotal axis as the supporting point. The comoving element stirs and flattens the shredded paper, thereby reducing the space between shredded paper and increasing the capacity of the trash bin.

1 . A stirring device disposed in a trash bin for stirring and flattening paper chips comprising:
 an actuator; and   a comoving element, which is pivotally connected with said actuator so as   to move synchronously with the actuator.   
   
   
       2 . The stirring device of  claim 1 , wherein said actuator is a pedal. 
   
   
       3 . The stirring device of  claim 1 , wherein said comoving element is a stirring element. 
   
   
       4 . The stirring device of  claim 3 , wherein said stirring element is a stirring rod. 
   
   
       5 . The stirring device of  claim 1 , wherein said comoving element performs an up-and-down reciprocal motion concurrently with said actuator using a pivotal axis as the pivot point. 
   
   
       6 . The stirring device of  claim 1 , wherein said comoving element is a link lever mechanism. 
   
   
       7 . The stirring device of  claim 6 , wherein said link lever mechanism includes a first link lever and a second link lever. 
   
   
       8 . The stirring device of  claim 7 , wherein the fixed end of said first link lever is connected with said actuator, the free end of said first link lever is connected with a stroke limiting groove of said second link lever via the pivotal axis, the fixed end of said second link lever is pivotally connected to the interior bottom of the trash bin, and the free end of said second link lever is connected with the stirring rod.
