An electromagnetic field is generated to secure the male coupler in the female coupler.
Claims16
A blender comprising:
- a base,
- a motor within the base,
- a jar supported by and detachable from the base,
- a blade assembly within the jar,
- a male coupler coupled to the blade assembly, the male coupler being responsive to an electromagnetic field,
- a female coupler coupled to the motor, the female coupler being configured to receive the male coupler,
- a spring configured to urge the male coupler into contact with the female coupler, and
- means for generating an electromagnetic field that extends across the female coupler to secure the male coupler within the female coupler, the means for generating the electromagnetic field comprising a coil which surrounds the female coupler.
