Abstract

A light emitting tooth brush having whitening and sterilizing effects includes 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. 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. Thus, the light emitting tooth brush may achieve the sterilizing effect and may achieve the effect of cleaning and whitening the user'"'"'s teeth.

Claims

1. 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.

2. The light emitting tooth brush having whitening and sterilizing effects in accordance with claim 1, further comprising a support plate mounted on a top of the brush head to closely seal the brush head, so that the circuit board is closely mounted in the brush head by the support plate.

3. The light emitting tooth brush having whitening and sterilizing effects in accordance with claim 2, wherein the brush head is formed with a receiving space for receiving the circuit board, and the support plate is mounted on a top of the receiving space of the brush head to closely seal the circuit board in the brush head.

4. The light emitting tooth brush having whitening and sterilizing effects in accordance with claim 2, wherein the support plate is provided with multiple brushes.

5. The light emitting tooth brush having whitening and sterilizing effects in accordance with claim 1, wherein the circuit board is provided with and a plurality of resistors to adjust a light emitting strength of the light emitting member of the circuit board.

6. The light emitting tooth brush having whitening and sterilizing effects in accordance with claim 1, wherein the light emitting member of the circuit board may emit ultraviolet rays, viewable rays, and may emit infrared rays.

7. The light emitting tooth brush having whitening and sterilizing effects in accordance with claim 1, wherein the light emitting member of the circuit board is a light emitting diode.

8. The light emitting tooth brush having whitening and sterilizing effects in accordance with claim 1, wherein the light emitting member of the circuit board is a laser diode.
