High-speed automatic dental flosser

摘要

A high-speed automatic dental flosser (10) includes a detachably connected flossing attachment (12) having a pair of flossing tines (46) and (48) for supporting a movable floss span (47) to floss teeth, a floss supply spool (15) for continuously supplying fresh floss spans, and a floss take-up spool (17) includes a built-in floss gripper. A power driver (14) includes a dual-shaft geared motor (20) having an anterior drive shaft (22) drivingly connectable to the take-up spool and a posterior drive shaft (24) for drivingly rotating an eccentrically supported weight (40) to oscillate the floss span. An electric momentary switch (28) actuates the motor energized by a power cell (26). A built-in floss-cutter (29) is provided for cutting off used floss. An alternative flossing attachment (12B) includes an alternative floss gripper built into a take-up spool (39). Additional flossing attachments (12C) and (12D) are included.

主权项

1. A dental flosser attachment detachably connectable to a power driver, the attachment comprising:
a bifurcated member forming a pair of flossing tines for movably supporting a dental floss span between said tines for flossing teeth; a rotatably supported floss supply spool connected to said bifurcated member for replacing used floss spans with fresh floss spans; a rotatably supported floss take-up spool connected to said bifurcated member for being driven by said driver to wind used floss drawn from said tines; and a fluid-tight capsule enclosing said take-up spool for preventing escape of odorous gas from inside of said capsule while allowing entry and winding of used floss therein, wherein said take-up spool is at least partially submerged in an antiseptic fluid for inhibiting bacterial activity in said capsule.
