Abstract

A gum massaging tool includes a handle portion which accommodates electric or mechanical members and in which a selector switch is provided in an exposed manner; a fixed shaft portion that is fixed to the handle portion so as to extend from one end of the handle portion and is heated according to an operation of the selector switch; a gum contact portion that is rotatable around a distal end portion of the fixed shaft portion and that includes a carbon body which receives heat from the fixed shaft portion and transfers the heat to a gum contacting surface; and a supporting portion that is rotatably engaged with and supports the gum contact portion and is detachably attached to the handle portion.

First claim

The invention claimed is:

1. A gum massaging tool comprising:
a handle portion which accommodates electrical or mechanical members and in which a selector switch is provided in an exposed manner;
a heating element that is heated by supplied power in response to an operation on the selector switch;
a gum contact portion that includes only one carbon body in which carbon crystal structures are condensed by baking and integrated with each other, the carbon body transfers heat from the heating element directly to gums by heat conduction and radiates an increasing amount of far-infrared rays with increasing temperature, so that the temperature of the gums is increased by a conduction heat and a radiation heat of the far-infrared rays;
a temperature detecting portion that detects a temperature so as to control the heating element; and
a supporting portion that is an elongated member and supports the gum contact portion and that is connected to the handle portion.

2. The gum massaging tool according to claim 1 , wherein:
the electrical or mechanical members include a motor; and
the gum contact portion is vibrated by a rotational movement of the motor by the supplied power in response to an operation of the selector switch.

3. The gum massaging tool according to claim 1 , wherein the gum contact portion includes a coating of diamond-like carbon (DLC) which is located on a surface of the carbon body.

4. The gum massaging tool according to claim 1 , wherein the gum massaging tool maintains a temperature of the gums at about 37° C.
