Automatic dental flossing device
First Claim
1. A power-driven fully automatic dental flossing device, wherein a dental floss is automatically reciprocated or continually run in one direction, and said device comprising:
- (a) housing means containing an apparatus for automatically manipulating the dental floss, and formed with a frame comprising an openable and replaceable upper casing, a bottom casing, and a rear casing, and two tines attached to a forked arm extending from the upper casing;
(b) guide means formed on said upper casing for guiding the dental floss through a proper path to accomplish desired functions;
(c) reel means mounted in said upper casing of said housing means for supplying fresh dental floss and taking up used floss, for winding the dental floss in one direction at a time, and for reciprocating the floss back and forth;
(d) transmission means installed in the bottom casing for transmitting power and driving said reel means to accomplish automatic manipulation of the dental floss;
(e) operating switch means for switching on and off said device to reciprocate the dental floss, and for holding said dental floss;
(f) winding switch means for switching on and off said device to continually wind the dental floss in one direction at a time back and forth;
(g) power means installed in said rear casing to provide power for automatically manipulating the dental floss; and
(h) slotted tube conducting means on said tines of said forked arm for conducting the dental floss across said tines and integrating tips of said tines against cracking and wearing.

Abstract
A power-driven dental flossing device has an elongate housing of three casings with an extending housing arm forked at its front, which contains dental floss reels, a dividing gear system, dental floss operating and winding switches, and a powered motor with batteries and/or a transformer. Dental floss across two tines of the forked arm is wound on the two reels, one of which supplies fresh dental floss, the other takes up used floss. The dental floss can be automatically reciprocated between the tines and teeth by pulling an operating switch backward, and also can be manipulated manually by pushing the same operating switch forward. The floss can also be automatically wound in one direction at time to provide a fresh length of the floss, or to rewind it back at any time. The floss reels are driven by the gear system which comprises pinions installed on reel shafts, and a main dividing gear with partially geared circumference to drive each one of pinions alternately, therefore the dental floss can automatically complete reciprocating motion to accomplish teeth cleaning. The main gear can also be slid to an upper or lower position on its shaft where only one pinion could be driven by the main gear, therefore the dental floss will be continually wound only in one direction at a time.
