Abstract
The power toothbrush includes a brushhead arm () and a brush element () at a distal end thereof. A V-spring assembly () converts the movement of a power drive assembly in a back-and-forth movement. A mounting member () at the rear end of the V-spring assembly provides a base for a magnet (). The back end of the V-spring assembly is displaced in accordance with pressure applied to the brush member. A Hall effect sensor () is mounted within the changing magnetic field produced by the magnet as the rear end of the V-spring assembly is displaced due to pressure on the brushhead. A processor () is responsive to the output from the Hall sensor and provides an indication when the pressure exceeds a threshold value.
