Abstract
Disclosed herein is a toothbrush. The toothbrush (1) includes a head (2), and a through hole (3) formed vertically through the head. The through hole (3) is formed in one or more portions by a predetermined length at a predetermined portion around a front, back, left or right of the bristle body (5) to prevent the bristle body (5) from being separated from the head (2). The bristle body (5) and the head (2) are connected to each other by one or more connecting portions. This toothbrush enables the bristle body implanted with bristles to freely and flexibly move upwards, downwards, leftwards or rightwards in the through hole of the head, so that the bristle body flexibly moves so as to adapt to various shapes of the teeth when brushing the teeth, thereby maximizing the contact area between the teeth and the bristles as well as the brushing effect.
Claims6
A toothbrush, comprising:
- a head,
- wherein the head comprises:
- at least two through holes formed vertically through the head;
- at least one elastically movable bristle body substantially surrounded by the at least two through holes;
- a fixed portion disposed at a peripheral area of the at least one elastically movable bristle body;
- and
- at least two elastic connection portions unitarily connected to the fixed portion, thereby enabling the at least one elastically movable bristle body to move relative to the fixed portion when the toothbrush is used for brushing one's teeth with a compressive force applied to the at least one elastically movable bristle body;
- and
- a reinforcing member configured to reinforce an elastic operation of the at least one bristle body in the head of the toothbrush, wherein the at least one elastically movable bristle body is connected to the head by the reinforcing member and is selected from among a leaf spring, a double wire, a twisted wire, and a coil spring.
A toothbrush, comprising:
- a head,
- wherein the head comprises:
- at least two through holes formed vertically through the head;
- at least one elastically movable bristle body substantially surrounded by the at least two through holes;
- a fixed portion disposed at a peripheral area of the at least one elastically movable bristle body;
- at least two elastic connection portions unitarily connected to the fixed portion, thereby enabling the at least one elastically movable bristle body to move relative to the fixed portion when the toothbrush is used for brushing one's teeth with a compressive force applied to the at least one elastically movable bristle body, and
- wherein the at least one elastically movable bristle body comprises a plurality of individual bristle bodies, a plurality of gaps disposed therebetween, and a plurality of elastic connecting members placed between the plurality of individual bristle bodies, wherein each of said elastic connecting members is in a shape of a pin and made of a material selected from among soft synthetic resin, silicone, and synthetic rubber.
