Abstract

The present invention discloses the present invention discloses a toothbrush head for engaging to an automatic toothbrush base having a motor shaft for actuating a vibration. The toothbrush head includes a tubular adapter for adapting the vibrating motor shaft the tubular adapter further engaging and transferring the vibration to a swing rod. The toothbrush head further includes an off center pin engaged to the swing rod. The toothbrush head further includes a pair of parallel pins for disposing the off center pin therein and the pair of parallel pins are fixed onto a bristle plate whereby the off center pin is moved along the pair of parallel pin for generating a corresponding vibration on the bristle plate.

Claims

1. A toothbrush head for engaging to an automatic toothbrush base having a motor shaft for actuating a vibration, said toothbrush head comprising:

a tubular adapter for adapting said vibrating motor shaft said tubular adapter further engaging and transferring said vibration to a swing rod;

an off center pin engaged to said swing rod;

a pair of parallel pins for disposing said off center pin therein and said pair of parallel pins are fixed onto a bristle plate whereby said off center pin is moved along said pair of parallel pin for generating a corresponding vibration on said bristle plate.

2. The toothbrush head of claim 1 further comprising:

a guiding connector disposed next to said swing rod for guiding said swinging rod.

3. The toothbrush head of claim 1 further comprising:

a driving shaft for engaging said motor shaft and said swinging rod for transferring said vibration from said motor shaft to said swinging rod.

4. The toothbrush head of claim 1 further comprising:

a color ring for distinguishing a user of said toothbrush head.

5. The toothbrush head of claim 1 further comprising:

a central shaft for mounting and supporting said bristle plate to enable a vibration movement along a rotational axis perpendicular to said bristle plate.

6. A toothbrush head for engaging to an automatic toothbrush base having a motor shaft for actuating a vibration, said toothbrush head comprising:

a tubular adapter for adapting said vibrating motor shaft said tubular adapter further engaging and transferring said vibration to a swing rod;

an off center pin engaged to said swing rod;

an inclined elliptical trough for disposing said off center pin therein and said elliptical trough are fixed onto a bristle plate whereby said off center pin is vibrated and moved in said inclined elliptical trough for generating a corresponding vibration on said bristle plate.

7. The toothbrush head of claim 6 further comprising:

a guiding connector disposed next to said swing rod for guiding said swinging rod.

8. The toothbrush head of claim 6 further comprising:

a driving shaft for engaging said motor shaft and said swinging rod for transferring said vibration from said motor shaft to said swinging rod.

9. The toothbrush head of claim 6 further comprising:

a color ring for distinguishing a user of said toothbrush head.

10. The toothbrush head of claim 6 further comprising:

a central shaft for mounting and supporting said bristle plate to enable a vibration movement along a rotational axis perpendicular to said bristle plate.
