Abstract
An electrical toothbrush includes an elongated handle body, a motor received in the handle body to drive a driving shaft to rotate, and a brush head including an elongated brush arm detachably mounted to the driving shaft and arranged when the driving shaft is driven to rotate, the brush arm is rotated correspondingly and a plurality of brushing bristles radially and outwardly extended from the brush arm for generating a rolling motion to substantially brush a user's teeth when the brush arm is driven to rotate, wherein the brush arm is arranged for locating at a position that the brushing bristles are tangentially rolling on the tooth surface to brush the tooth surface and are consequently brush the gumline at a predetermined angle to remove plaque from the areas between teeth and around the gums.
Claims20
An electrical toothbrush, comprising:
- an elongated handle body having a receiving cavity and a coupling end;
- a power unit comprising a motor received in said receiving cavity and a driving shaft which is outwardly extended from said coupling end of said handle body and is driven to rotate by said motor;
- and
- a brush head, which comprises:
- an elongated brush arm detachably mounted to said driving shaft and arranged when said driving shaft is driven to rotate, said brush arm is rotated correspondingly;
- and
- a plurality of brushing bristles radially and outwardly extended from said brush arm for generating a rolling motion to substantially brush a user's teeth when said brush arm is driven to rotate, wherein said brush arm is arranged for locating at a position that said brushing bristles are tangentially rolling on the tooth surface to brush the tooth surface and are consequently brush the gumline at a predetermined angle to remove plaque from the areas between the teeth and around the gums.
A brush head for detachably mounting to an electrical toothbrush having a driving shaft to generate a rotational power, comprising:
- an elongated brush arm adapted for detachably mounting to said driving shaft and arranged when said driving shaft is driven to rotate, said brush arm is rotated correspondingly;
- and
- a plurality of brushing bristles radially and outwardly extended from said brush arm for generating a rolling motion to substantially brush a user's teeth when said brush arm is driven to rotate, wherein said brush arm is arranged for locating at a position that said brushing bristles are tangentially rolling on the tooth surface to brush the tooth surface and are consequently brush the gumline at a predetermined angle to remove plaque from the areas between the teeth and around the gums.
