Abstract:
A powered toothbrush apparatus with capacitive touch control is disclosed. The tooth brush includes a head portion having an oscillating tuft block driven by a motor, a handle portion, and an elastically deformable capacitive touch control panel mounted in the handle portion. In one embodiment, the control panel includes a plurality of capacitance sensor buttons each having movable sensor targets paired with a corresponding capacitance sensor electrically connected to a programmable microprocessor. Applying finger pressure on the control panel adjacent a sensor target changes capacitance of the sensor button. The microprocessor detects the change in capacitance, which controls the operating mode of the toothbrush including on/off, motor speed, brushing mode such as pulse, or other. A related operating method is disclosed.
Abstract:
A powered toothbrush head that, in one embodiment, includes a head portion including a first movable tuft block configured for holding tooth cleaning elements. The first movable tuft block is operably connected to a motor-driven drift shaft for movement. An eccentric cam formed on the shaft drives the first movable tuft block via engagement with a slot formed in the body of the first movable tuft block. The first movable tuft block is movable in a combination oscillating motion comprising vertical motion and lateral pivoting or tilting motion upon rotation of the drive shaft. A related method for oscillating the first movable tuft block is disclosed.

A powered toothbrush apparatus with capacitive touch control, which includes a head portion having an oscillating tuft block driven by a motor, a handle portion, and an elastically deformable capacitive touch control panel mounted in the handle portion. In one embodiment, the control panel includes movable sensor targets each paired with a corresponding capacitance sensor electrically connected to a programmable microprocessor. Applying finger pressure on the control panel adjacent a sensor target operates to change the capacitance of the respective sensor target-sensor pair. The microprocessor detects the change in capacitance, which may be used to control the motor speed for changing the oscillation rate of the tuft block. In one embodiment, a linear array of sensor targets-sensors is provided which is activated by a sliding finger or thumb motion across the array. A related operating method is disclosed.
