Abstract
A tooth bleaching device provided with: a production device that produces an active component for bleaching a tooth; a mouthpiece in which a supply opening, through which the active component produced by the production device is supplied inside the oral cavity, is formed; and a connecting part that connects the production device and the mouthpiece.
Claims18
A teeth whitening device comprising:
- a generator that generates a teeth whitening fluid which is a gas that contains electrically charged microparticle water;
- a mouthpiece having a shape configured to be held by one or more of teeth, gums, and lips of a user to keep the mouthpiece in the mouth of the user so that the user can use the teeth whitening device hands free;
- and
- a coupling portion that couples the generator and the mouthpiece to each other,
- wherein the mouthpiece includes a supply port that supplies the teeth whitening fluid generated by the generator into an oral cavity, an inlet-side passage, to which the coupling portion is connected, and an outlet-side passage, which does not include the supply port and guides gas flowing through the inlet-side passage to the supply port,
- wherein the generator is configured to generate condensed water by cooling and to atomize the condensed water by generating electric discharging so as to generate the electrically charged microparticle water, which includes radical species serving as teeth-whitening active ingredients, and
- wherein the teeth whitening device is configured to cause the gas that contains the electrically charged microparticle water flowing from the generator to the mouthpiece through the coupling portion.

A teeth whitening device comprising:
- a generator that generates a gaseous teeth whitening fluid when activated;
- and
- a mouthpiece connected to the generator in a fluid-communicable manner via a coupling portion that couples the generator and the mouthpiece to each other, the mouthpiece having a shape configured to be held by one or more of teeth, gums, and lips of a user to keep the mouthpiece in the mouth of the user so that the user can use the teeth whitening device hands free,
- wherein the mouthpiece includes a U-shaped outer curved element, a supply port that supplies the gaseous teeth whitening fluid, an inlet-side passage, to which the coupling portion is connected, and an outlet-side passage, which does not include the supply port and guides the gaseous teeth whitening fluid flowing through the inlet-side passage to the supply port,
- wherein the generator is configured to generate condensed water on an atomization electrode by cooling the atomization electrode and to atomize the condensed water by generating electric discharging through the atomization electrode so as to generate the electrically charged microparticle water, which includes radical species serving as teeth-whitening active ingredients, wherein the gaseous teeth whitening fluid includes the electrically charged microparticle water dispersed in air, and
- wherein the teeth whitening device is configured to cause the gaseous teeth whitening fluid flowing from the generator to the mouthpiece through the coupling portion.
