Blender

Abstract

A food-processing device for blending and mixing food comprises a mixing vessel, a blade holder, and a motor base. The motor is a high power motor. The device has various safety features designed for the high power motor. The blade holder comprises a safety mechanism that prevents the motor base from operating without the mixing vessel covering the blade. The mixing vessel also contains emitters that interact with detectors on the motor base that can allow a user to select an alternate blend speed according to the mixing vessel that is attached.

What is claimed is: 
     
         1 . A food processing device, comprising:
 a plurality of mixing vessels, said mixing vessels having:
 at least one open end; 
 a protrusion located proximately to said at least one open end, said protrusion having at least one emitter embedded in said protrusion; 
   a blade holder having at least one blade, said blade holder is capable of being removably affixed to said at least one open end of said mixing vessels,   a motor base capable of receiving said blade holder affixed to said mixing vessels, said motor base having:
 a motor for driving said at least one blade of said blade holder; 
 a top surface for receiving said blade holder, 
 a recess on said top surface for receiving said protrusion of said mixing vessels; 
 wherein said recess has at least one detector embedded in said recess for detecting a signal from said at least one emitter in said protrusion of said mixing vessels to power on the motor; and, 
   wherein said at least one emitter embedded in said protrusion is capable of emitting a signal to said at least one detector embedded in said recess to activate an alternative blend speed depending on the mixing vessel that is attached.   
     
     
         2 . The device of  claim 1 , wherein:
 The plurality of mixing vessels has at least two open ends;   Wherein said first open end of said mixing vessel is adapted to be affixed to said blade holder; and,   said second open end of said mixing vessel is adapted to be affixed to a removable lid.   
     
     
         3 . The device of  claim 1 , wherein:
 Said mixing vessel has a lip located proximately to said at least one open end and extending radially outward from an exterior surface of said mixing vessel, said lip having at least a second emitter embedded in said lip.   
     
     
         4 . The device of  claim 3 , wherein:
 Said motor base has at least a second detector embedded on the top surface of said motor base for detecting a signal from said at least one emitter in said lip of said mixing vessel;   Wherein the motor base differentiates said plurality of said mixing tables through the interaction between said second emitter and said second detector.   
     
     
         5 . The device of  claim 2 , wherein at least one alternative blending speed blends the container content at a rate such that contents in said mixing vessel can be heated. 
     
     
         6 . The device of  claim 1 , further comprising a user interface located on said motor base, said user interface capable of activating an alternative blend speed of said motor depending on said signal from said emitter in said protrusion in said mixing vessel to said detector in said recess of said motor base. 
     
     
         7 . The device of  claim 1 , wherein said at least one emitter is a magnet. 
     
     
         8 . The device of  claim 1 , wherein said at least one detector embedded in the motor base is a hall sensor. 
     
     
         9 . The device of  claim 4 , wherein said user interface displays the blending speed that is active. 
     
     
         10 . A food processing device, comprising:
 a plurality of mixing vessels, said mixing vessels having:
 at least one open end; 
 a protrusion located in proximity to said at least one open end, said protrusion having at least one emitter embedded in said protrusion; 
   a blade holder having at least one blade, said blade holder is capable of being removably affixed to said at least one open end of said mixing vessels,   a motor base capable of receiving said blade holder affixed to said mixing vessel, said motor base having:
 a motor for driving said at least one blade of said blade holder; 
 a top surface for receiving said blade holder, 
 a recess on said top surface for receiving said protrusion on said mixing vessel; 
 wherein said recess has at least one detector embedded in said recess for detecting a signal from said at least one emitter in said protrusion of said mixing vessel to power on the motor; and, 
 wherein said at least one emitter embedded in said protrusion is capable of emitting a signal to said at least one detector embedded in said recess to activate an alternative blend speed depending on the mixing vessel that is attached; and, 
 wherein the motor base further comprises a user interface capable of activating an alternative blend speed of said motor depending on said signal from said emitter in said protrusion in said mixing vessel to said detector in said recess of said motor base.
