ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a light emitting tooth brush having whitening and sterilizing effects, and more particularly to a light emitting tooth brush that may achieve the sterilizing effect and may achieve the effect of cleaning and whitening the user's teeth.
2. Description of the Related Art
A conventional tooth brush may co-operate with the tooth paste to brush the user's teeth. However, the conventional tooth brush cannot achieve the sterilizing effect and cannot achieve the effect of whitening the user's teeth, thereby decreasing the utility and versatility of the conventional tooth brush.
SUMMARY OF THE INVENTION
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional tooth brush.
The primary objective of the present invention is to provide a light emitting tooth brush having whitening and sterilizing effects, wherein the light emitting member of the circuit board may emit ultraviolet rays with shorter wavelengths (with a greater energy), thereby achieving a sterilizing effect.
Another objective of the present invention is to provide a light emitting tooth brush having whitening and sterilizing effects, wherein the light emitting tooth brush may promote the optical chemical reaction between the tooth paste and the surface of the user's teeth, so that the light emitting tooth brush may clean and whiten the surface of the user's teeth efficiently, thereby achieving the effect of cleaning and whitening the user's teeth.
In accordance with the present invention, there is provided a light emitting tooth brush having whitening and sterilizing effects, comprising a handle having one end provided with a light permeable brush head, a control switch mounted in the handle, and a circuit board mounted in the brush head, wherein: the circuit board is electrically connected to the control switch, and is provided with a light emitting member which may emit optical waves having a specified wavelength through the light permeable brush head.
