Abstract

The present relates to an improved structure of a multifunctional tooth-brush comprising a handle body, a bristles seat, an actuating rod, a teeth-polishing disc, a positioning peg and a spring. The bristles mounted on the bristles seat brushes the teeth when the tooth-brush is applied to the teeth in horizontal direction. The polishing disc mounted on the bristles seat polishes the teeth during the process of brushing the teeth.

Claims

1. A multifunctional toothbrush comprising

(a) a handle having an elongated top covering and a bottom covering enclosing a hollow space, the edge of the bottom covering being provided with a plurality of engaging dovetail joints in combination with a plurality of mounting holes on the edge of the top covering, the enclosed hollow space including an elongated slot, a curving slot and a spring chamber and a partition wall having a notch being formed in between the spring chamber and the curving slot, the surface of the top covering at the position corresponding to the spring chamber being provided with a plurality of water-discharging holes;

(b) a bristles seat, having a top housing seat and a bottom housing seat, the housing seats individually having a head portion, and an extension portion, a plurality of dovetail joints being provided on the top surface of the bottom housing seat to combine with a plurality of mounting holes on the bottom surface of the top housing seat, a plurality of fixed bristles being mounted on the top surface of the top housing seat along the edge thereof, a circular hole and a rectangular opening being provided adjacent to each other on the surface of the top housing seat, wherein the top end of the bottom housing seat is provided with a peg mounting hole in alignment with the circular hole at the head portion of the top housing seat, and a cylindrical recess is in alignment with the rectangular opening on the top housing seat, at one edge of the cylindrical recess, adjacent to the extension portion, a semi-circular slot is provided, and along the extension portion, an elongated semi-circular slot is extended until the end thereof;

(c) an actuating rod being an elongated rod having a small shaft having a protrusion mounted vertically to the small shaft, at the top end thereof, a cylindrical shaft of larger diameter being mounted vertically with a row of bristles, and a vertical cross-shaped member being provided onto the rod, close to the rear end of the actuating rod, and the rear end of the rod being provided with a circular blocking disc;

(d) a teeth-polishing disc having a plurality of tiny particle on the surface thereof, and the center, at the bottom surface of the disc being provided with a polygonal hole with a plurality of vertical slots at the external edge thereof;

(e) a positioning peg having the head portion being fabricated into a polygonal head; and

(f) a spring located within the spring chamber, thereby, while brushing the teeth, the hand holds the handle and when the handle is pushed towards the bristles seat, the cross-shaped member on the actuating rod moves along the curving slot, which causes the protrusion at the tip of the actuating rod to move simultaneous with the movement of the actuating rod and drives the polishing disc, and when the bristles seat and the actuating rod retract back into the handle until the blocking disc compresses the spring, the spring force of the spring cause the actuating rod and the cross-shaped member to move towards the bristles seat along the curving slot again, thus, the polishing disc rotates to polish the teeth.
