Abstract
A toothpaste dispensing automatic toothbrush includes a head member mounted atop a body member with a brush head releasably coupled to the head member. A reservoir for containing toothpaste is positioned in the body member along with a pump assembly and first motor. The first motor is connected to a battery and drives the pump assembly when actuated by depression of a first switch whereby to urge toothpaste from the reservoir through a channel and onto bristles of the brush head. The brush head includes a rotor with rotor bristles that is operatively connected to a second motor. The second motor may be energized upon actuation of a second switch to cause movement of the rotor. A recharging base may be included for recharging a rechargeable toothbrush battery.
Claims19
A toothpaste dispensing automatic toothbrush, comprising:
- a body member having opposed first and second ends and defining an interior space;
- a head member having a lower end coupled to said first end of said body member and having an upper end;
- a brush head releasably coupled to said head member upper end and having a plurality of brush head bristles extending outwardly therefrom, said brush head having a hollow configuration and defining a plurality of apertures proximate said plurality of brush head bristles;
- a reservoir positioned in said interior space adjacent said first end for storing toothpaste, said reservoir having upper and lower walls;
- a channel interconnecting said reservoir and said plurality of apertures;
- a piston mounted in said reservoir for movement between said upper and lower walls, whereby a piston movement toward said upper wall urges said toothpaste through said channel to said plurality of apertures in said brush head;
- a battery positioned in said interior space;
- a first motor positioned in said interior space and operatively coupled to said piston for driving said piston;
- and
- a first switch mounted on said body member and electrically connected to said battery and to said first motor for selectively energizing said first motor, whereby to dispense said toothpaste through said brush head apertures and onto said brush head bristles the brush head includes a rotor having a plurality of rotor bristles extending outwardly therefrom, the toothbrush further comprising a second motor positioned in the head member and operatively connected to the rotor;
- and a second switch mounted on the body member and electrically connected to the battery and to the second motor for selectively energizing the second motor, whereby to selectively rotate the plurality of rotor bristles.
A toothpaste dispensing automatic toothbrush, comprising:
- a body member having opposed first and second ends and defining an interior space;
- a head member having a lower end coupled to said first end of said body member and having an upper end;
- a brush head releasably coupled to said head member upper end, said brush head having a hollow configuration and defining a plurality of apertures, said brush head further comprising:
- a plurality of brush head bristles extending outwardly therefrom and positioned proximate said plurality of apertures;
- a rotor having a plurality of rotor bristles extending outwardly therefrom;
- a reservoir positioned in said interior space adjacent said first end for storing toothpaste, said reservoir having upper and lower walls;
- a battery positioned in said interior space;
- a channel interconnecting said reservoir and said plurality of apertures;
- a pump assembly operatively coupled to said reservoir for selectively urging said toothpaste into said channel;
- a first motor coupled to said pump assembly for driving said pump assembly when energized;
- a first switch mounted on said body member and electrically connected to said battery and to said first motor for selectively energizing said first motor, whereby to dispense said toothpaste through said brush head apertures and onto said brush head bristles;
- a second motor positioned in said head member and operatively coupled to said rotor;
- and
- a second switch mounted on said body member and electrically connected to said battery and to said second motor for selectively energizing said second motor, whereby to selectively cause movement of said plurality of rotor bristles.
