Hand held dental flossing device and method of operating the same

A method for operating the hand-held dental flossing device, comprising:

• rotating, by a user, a knurled disc of a first spool and a second spool for discharging a length of a dental floss from the first spool and guiding the dental floss to the second spool through a head for performing flossing of teeth;
• controlling, by the user, the tension of the dental floss by moving the floating platform towards the head against an elastic member when the user increasing and decreasing the tension of the dental floss by rotating the second spool and holding the first spool, and by rotating the first spool and holding the second spool, respectively;
• and
• enabling, by the hand-held dental flossing device, the user to control the tension of the dental floss at various modes by operating the first spool and the second spool, thereby maintaining equal tension of the dental floss and preventing the dental floss from tangling and shedding during flossing of teeth.

A hand-held dental flossing device, comprising:

• a body having a handle, wherein said handle having a split structure at one end and a palm rest at another end, which are configured for providing an ergonomic grip for a user to secure the hand-held dental flossing device through at least one hand during dental flossing operations;
• a head with a plurality of arms securely affixed to one end of said handle, wherein said plurality of arms comprises one or more closed loops, which is configured to facilitate the passage of a dental floss, which is used for flossing teeth during the dental flossing operations;
• a floating platform having a holding member configured to slidably position within said handle, wherein said floating platform comprises:
• a case member defining a chamber;
• a first spool with a dental floss rotatably mounted within said chamber, wherein said first spool comprises a primary worm gear profile, which is configured to engage with a worm, that is rotatably mounted on an axle shaft protruding outward through the handle and rotated manually by a user for winding and unwinding of the dental floss;
• a second spool configured to receive the used dental floss and having a secondary worm gear teeth profile, wherein said second spool is rotatably mounted within said chamber and adapted to engage with said worm for winding the used dental floss back onto the second spool;
• a pair of clutches mounted on the axle shaft aligned with the worm, wherein the pair of clutches comprises:
• a primary clutch connected to the first spool via the worm for enabling the unwinding of new dental floss when engaged;
• a secondary clutch connected to the second spool via the worm for enabling the winding of used dental floss when engaged;
• and
• plurality of bushing members located at either end of the worm, which is configured to facilitate a slidable movement of the worm to selectively engage and disengage the primary clutch and the secondary clutch by exerting pressure via a flexible spring, thereby facilitating the user to independently control the rotation of the first spool and the second spool upon rotating the worm,
• wherein said floating platform is adapted to move through said handle towards said head against an elastic member,
• wherein the elastic member is flexibly mounted within said handle when the user increases and decreases the tension of the dental floss at said head by rotating said worm at the second spool while holding the worm at said first spool, and by rotating the worm at said first spool while holding the worm at said second spool.

A method for operating the hand-held dental flossing device, comprising:

• rotating, by a user, a worm connected to a first spool and a second spool for dispensing a length of new dental floss from the first spool and guiding the dental floss through a head of the hand-held dental flossing device to the second spool for collecting used dental floss while performing dental flossing operations;
• engaging, by the user, a primary clutch via a bushing member to enable the unwinding of the dental floss from the first spool by rotating the worm while holding the second spool stationary;
• engaging, by the user, a secondary clutch via the bushing member to enable the winding of used dental floss onto the second spool by rotating the worm while holding the first spool stationary;
• rotating, by the user, the worm at the first spool in a clockwise direction to increase the tension while holding the second spool stationary, and rotating the worm at the second spool in a counterclockwise direction to decrease the tension while holding the first spool stationary for performing dental flossing operations;
• actuating, by the user, the secondary clutch in a unidirectional mode by rotating the worm at the second spool in at least one direction, thereby ensuring that used floss does not rewind onto the first spool during the dental flossing operations;
• and
• disengaging, by the user, the primary clutch and the secondary clutch to release tension and facilitate easy removal and replacement of the first spool for new dental floss and the second spool for used dental floss.
