Abstract

A handheld skin exfoliating apparatus has handle and head portions with two drums having different abrasiveness mounted on opposite sides of the head portion. A drive motor and gears are mounted to the handle and/or head portions and operatives to rotate the drums for exfoliate skin when a respective outer surface of one drum contacts the skin.

Claims

1. A handheld skin exfoliating apparatus comprising:

a handle portion adapted to be held in a hand of a user;

a head portion connected to the handle portion and having opposite sides;

a first drum having a first outer surface, the first drum being mounted for rotation to the head portion with at least part of the first outer surface being exposed at one of the sides of the head portion;

a second drum having a second outer surface, the second drum being mounted for rotation to the head portion with at least part of the second outer surface being exposed at an opposite one of the sides of the head portion;

the first outer surface being abrasive to skin of the user and having a first level of abrasiveness;

the second outer surface being abrasive to the skin of the user and having a second level of abrasiveness that is different from the first level of abrasiveness; and

drive means mounted to at least one of the handle and head portions, the drive means operatively connected to each of the first and second drums for rotating each one of the drums at a rotation rate sufficient to exfoliate the skin when a respective one of the first and the second outer surface contacts the skin;

wherein the drive means comprises a motor having opposite sides and a shaft with a pair of ends, one of the pair of ends extending beyond one of the sides of the motor and the other one of the pair of ends extending beyond the other one of the sides of the motor, and a pair of gear trains, one of each of the pair of gear trains engaged between a respective one of the ends of the shaft and a respective one of the drums, each one of the gear trains comprising a shaft gear connected to a respective one of the ends of the shaft, a double gear having a large diameter portion meshed with the shaft gear and a small diameter portion, a single intermediate gear meshed with the small diameter portion of the double gear, and a drum gear attached on a respective one of the drums and meshed with the intermediate gear.

2. The apparatus of claim 1, wherein the head portion is curved in a plane transverse of a major axis of the handle portion so that the opposite sides of the head portion and the drums which are carried within the head portion are forward of a central part of the head portion to better expose the surfaces of the drums in use.

3. The apparatus of claim 1, wherein the motor is mounted in an area where the head and handle portion connect to each other.

4. The apparatus of claim 1, wherein the head portion is curved and the motor is located in the head portion.

5. A handheld skin exfoliating apparatus comprising:

a handle portion, head portion connected to the handle portion, two drums having different abrasiveness mounted on opposite sides of the head portion and a drive motor mounted to at least one of the handle and head portions and operatively connected to the drums to rotate the drums to exfoliate skin when a respective one of the outer surfaces of one of the drums contacts the skin;

wherein the drive motor comprises opposite sides and a shaft with a pair of ends, one of the pair of ends extending beyond one of the sides of the drive motor and the other one of the pair of ends extending beyond the other one of the sides of the drive motor, and a pair of gear trains, one of each of the pair of gear trains engaged between a respective one of the ends of the shaft and a respective one of the drums, each one of the gear trains comprising a shaft gear connected to a respective one of the ends of the shaft, a double gear having a large diameter portion meshed with the shaft gear and a small diameter portion, a single intermediate gear meshed with the small diameter portion of the double gear, and a drum gear attached on a respective one of the drums and meshed with the intermediate gear.

6. The apparatus of claim 5, wherein the head portion is curved in a plane transverse of a major axis of the handle portion so that the opposite sides of the head portion and the drums which are carried within the head portion are forward of a central part of the head portion to better expose the surfaces of the drums in use.

7. The apparatus of claim 5, wherein the drive motor is mounted in an area where the head and handle portion connect to each other.

8. The apparatus of claim 5, wherein the head portion is curved and the drive motor is located in the head portion.
