Blender with removable spindle and monitored reservoir

Abstract

A blender includes a spindle support, a spindle motor secured to the spindle support, an inner spindle drive shaft permanently coupled to the spindle motor, and a spindle assembly removably coupled to the spindle support. The spindle assembly includes a quick release coupler, a tube, and a blending tool fixed to an end of the tube. The blending tool includes a plurality of blades. The inner spindle drive shaft extends into the tube and is drivably coupled to the tube to transmit rotational energy from the spindle motor to blending tool via the tube when the spindle assembly is coupled to the spindle support.
