Abstract
A hair cutting device is provided with a magnetic drive assembly. The hair cutting device includes a cutting blade, a stationary blade and a magnetic drive assembly including a drive shaft coupled to a magnet and a bracket or yoke attached to the cutting blade. The bracket includes one or more magnets positioned on opposing sides of the drive shaft. The one or more magnets of the bracket and the magnet coupled to the drive shaft create an attractive and/or repulsive force between the magnet and the bracket generating linear movement of the bracket.
Claims20
A haircutter, comprising:
- a housing extending along a longitudinal axis;
- a motor positioned within the housing;
- a power source, the power source configured to selectively distribute energy to the motor;
- a drive assembly, the drive assembly comprising:
- a drive shaft coupled to the motor;
- a bracket comprising:
- a body comprising:
- a first side wall;
- and
- a second side wall, the first side wall and the second side wall positioned on opposing sides of the drive shaft;
- a first magnet positioned on the first side wall;
- and
- a second magnet positioned on the second side wall;
- and
- a drive magnet coupled to the drive shaft, wherein the drive magnet generates a driving force;
- a blade assembly, the blade assembly comprising:
- a stationary lower blade;
- and
- an upper blade supported relative to the stationary lower blade, the upper blade coupled to the drive assembly, wherein the drive assembly uses the energy from the power source to move the drive magnet relative to the bracket such that the upper blade moves over the stationary lower blade.
A magnetic drive assembly for a haircutter, the magnetic drive assembly comprising:
- a drive shaft positioned along an axis of rotation;
- a bracket comprising:
- a body comprising:
- a first side wall;
- and
- a second side wall, the first side wall and the second side wall positioned on opposing sides of the drive shaft;
- a first magnet positioned on the first side wall;
- and
- a second magnet positioned on the second side wall;
- and
- a drive magnet coupled to the drive shaft, wherein the drive magnet generates a driving force to move the bracket.
A magnetic drive assembly for a haircutter, the magnetic drive assembly comprising:
