Abstract

An automatic motor-driven blender cup with a leakage-free stirring apparatus includes a blender cup, an internal chamber, a mounting frame, a stirring shaft, a magnetic disk and a motor with a dry battery; wherein, said mounting frame and stirring shaft are disposed at the central position of the inside base wall of said blender cup; said magnetic disk is correspondently fixed inside of the bottom space of said internal chamber with central axial line in alignment with that of said stirring shaft without any physical link or contact each other; the stirring propeller on said stirring shaft will be magnetically inducted by said corresponding magnetic disk to simultaneously rotate in said internal chamber when said magnetic disk is driven by the output shaft of said motor; thus, not only the stirring effect of liquid or fluid in said internal chamber can be achieved, but also said liquid or fluid can be prevented from leakage and seepage out of the base wall of said blender cup so as to insure said motor free from premature defectively damage due to moisture erosion.

Claims3

Dependent claims

An automatic motor-driven blender cup with a leakage-free stirring apparatus comprising:

a blender cup including an internal chamber formed upward with opening on the top side and a handle disposed on the peripheral surface together with a push button;
an internal chamber having a hollow container and a miniature bearing notch indented in the center of the inside bottom with some upstanding clasps arranged for jutted around said bearing notch of said internal chamber;
a mounting frame having a opening downward cannular frame with flange at the bottom rim such that being securely buckled by all said upstanding clasps on said internal chamber;
a stirring shaft is formed with a cone-shaped front tip downward and a rear pin end pivoted in the top center of said mounting frame as well as a pair of horizontal stirring propellers, which being made of metal in good magnetic induction, is near the front shaft tip against the base wall of said internal chamber;
a magnetic disk is horizontally fixed on said output shaft of a motor with central axial line in alignment with that of said stirring shaft, and having some distance against the inner wall of the base portion of said internal chamber;
on each blade of said magnetic disk, a magnetic element is inset in correspondence with said stirring propeller of said stirring shaft;
and
said motor and dry battery are disposed inside at the bottommost of said blender cup.
