Abstract
A teeth cleaning system, which provides improved coverage or brushing area. The system includes an actuated tray comprises brushing elements. The brushing elements may be positioned to engage the front, rear, and top surfaces of the upper and lower jaw teeth. The actuation may be configured to oscillate the tray in a lateral direction which may brush all the surfaces of teeth simultaneously. Some embodiments include a higher density of bristles which increases the effectiveness of brushing. In addition, aspects of the system reduce the time spent brushing teeth.
Claims21
(canceled)
A teeth cleaning system comprising:
- a tray assembly that is configured to receive teeth of an upper jaw in an upper channel and teeth of a lower jaw in a lower channel and that includes:
- a mating element that is accessible along an outer arcuate wall that defines an outer periphery of the tray assembly;
- and
- a handle assembly that includes:
- a shaft that is connectable to the mating element of the tray assembly,
- a motor with a drive shaft that rotates during operation,
- a cam to which a proximal end of the shaft and the drive shaft of the motor are coupled,
- wherein the cam is configured to drive the proximal end of the shaft in a lateral direction in response to being rotated by the drive shaft of the motor, and
- a casing in which the motor, the cam, and the proximal end of the shaft are housed, while a distal end of the shaft remains external to the casing for connecting to the mating element of the tray assembly.
A teeth cleaning system comprising:
- a tray assembly that is configured to receive teeth of an upper jaw in an upper channel and teeth of a lower jaw in a lower channel;
- and
- a handle assembly that includes:
- a casing with an opening defined therein,
- a shaft that extends through the opening in the casing, such that a first end of the shaft is internal to the casing while a second end of the shaft is external to the casing and engageable with the tray assembly, and
- a sleeve that extends outwardly from the casing, encircling the opening and protecting the second end of the shaft.
A handle assembly for a teeth cleaning system that includes a tray assembly, the handle assembly comprising:
- a casing with an opening defined therein;
- a shaft that extends through the opening in the casing, such that a first end of the shaft is internal to the casing while a second end of the shaft is external to the casing and engageable with the tray assembly;
- a sleeve that extends outwardly from the casing, encircling the opening and entirely shielding the second end of the shaft;
- a motor with a drive shaft that rotates during operation;
- and
- a cam to which the first end of the shaft and the drive shaft of the motor are coupled,
- wherein the cam is configured to drive the shaft in response to being rotated by the drive shaft of the motor.
