Claims17
A dermabrasive device comprising:
- a portable housing, said portable housing is constructed of a lightweight, rigid material, said housing includes a barrel portion and a handle, said barrel portion and said handle are formed by a pair of abutting housing members, said barrel portion and said handle each includes an anterior end and a posterior end, wherein said posterior end of said barrel portion includes an inlet opening which is covered by a screen being suitably mounted over said inlet opening, said anterior end of said barrel portion includes an outlet opening;
- an electric drive motor, said electric drive motor is fixedly set along a central axis of said barrel portion;
- a drive shaft, said drive shaft integrally and axially extends from said electric drive motor, said drive shaft having an end mounted with a head receiving component, said electric drive motor is driven by electric power supplied from a plug socket through a power cord carrying a plug, wherein said power cord enters said posterior end of said handle through an opening, said power cord is provided with a strain relief suitably attached within an interior of said handle along said posterior end thereof, said power cord terminates in insulated lead wires which extend into a ground fault circuit interrupter,
- a plurality of heads, said plurality of heads are adapted for removable attachment to said head receiving component, said plurality of heads is rotatably driven by said electric drive motor;
- an On/Off switch, said On/Off switch is provided on a sidewall of said handle, said On/Off switch is adapted to actuate said electric drive motor;
- a controller switch, said controller switch is provided on said sidewall of said handle below said On/Off switch, wherein said controller switch includes a manual speed selector adapted to allow a user to manually control RPM speed of said electric drive motor, said manual speed selector comprises multiple settings selectable by the user to designate speed preference;
- and
- a layer of abrasive material, said layer of abrasive material is bonded to a forward face of each of said plurality of heads, said abrasive material extends downward a distance along a sidewall of each of said plurality of heads.
