Back-Cleansing Unit

Abstract

An automatic back-cleansing apparatus for fixing to a vertical bath or shower surface includes a main housing section having a rotating head receiving section with gear teeth for engaging rotating heads on a rotating disk section adjacent the main housing section. The rotating disk section includes a drive shaft attached to a first drive gear and each rotating head includes a second drive gear engaging the gear teeth. Each of the rotating heads includes an interchangeable brush configured for removable fixation on a mushroom shaped projection torsionally coupled to the second drive gear, and a reservoir disposed in the main housing section dispenses a liquid soap onto at least one of the rotating heads.

What is claimed is: 
     
         1 . An automatic back-cleansing apparatus for fixation on a vertical surface, the apparatus comprising:
 a main housing section;   a rotating head receiving section on the main housing section;   wall mounting means on the main housing section; and   a power producing means, wherein the rotating head receiving section comprises gear teeth engaging a plurality of rotating heads, each of the plurality of rotating heads disposed on a rotating disk section adjacent the main housing section.   
     
     
         2 . The apparatus of  claim 1  wherein the rotating disk section comprises a drive shaft attached to a first drive gear. 
     
     
         3 . The apparatus of  claim 1  wherein the main housing section is of unitary molded construction and wherein the gear teeth engage at least one second drive gear on the plurality of rotating heads. 
     
     
         4 . The apparatus of  claim 1  wherein the gear teeth are molded separately from the main housing section and are installed therein. 
     
     
         5 . The apparatus of  claim 1  wherein the rotating disk section rotates in a clockwise direction and the plurality of rotating heads rotates in a clockwise direction. 
     
     
         6 . The apparatus of  claim 1  wherein the rotating disk section is configured to rotate in a clockwise direction and the plurality of rotating heads is configured to rotate in a counterclockwise direction. 
     
     
         7 . The apparatus of  claim 1  wherein the plurality of rotating heads are interchangeable, comprising a feature selected from the list of rotating brushes, exfoliation heads, massage heads and applicator heads. 
     
     
         8 . The apparatus of  claim 1  wherein the plurality of rotating heads comprises six interchangeable rotating heads in each rotating disk section. 
     
     
         9 . The apparatus of  claim 1  further comprising an elastic interchangeable brush configured to stretch over a first central mushroom shaped projection attached to a first plate section, the first plate section engaging one of the plurality of the rotating heads. 
     
     
         10 . The apparatus of  claim 1  wherein each of the plurality of rotating heads comprises a brush carrier section, the brush carrier section comprising a second mushroom shaped projection, a carrier plate engaging one of the plurality of the rotating head. 
     
     
         11 . The apparatus of  claim 1  wherein the power producing means comprises a drive motor with integrated gearbox mounted on the main housing section. 
     
     
         12 . The apparatus of  claim 11  wherein the integrated gearbox reduces the speed of the plurality of rotating heads. 
     
     
         14 . The apparatus of  claim 1  wherein the power producing means comprises a drive motor selected from the list of electric motor, hydraulic motor, pneumatic motor and wind-up spring mechanism. 
     
     
         15 . The apparatus of  claim 1  wherein the power producing means comprises an electric drive motor powered by a battery located in a watertight compartment in a lower part of the main housing section. 
     
     
         16 . The apparatus of  claim 1  further comprising a user control mounted on the main housing to control the power producing means. 
     
     
         17 . The apparatus of  claim 1  further comprising an adjustable gear ratio configured to set the speed of the rotating disk sections and the plurality of rotating heads. 
     
     
         18 . The apparatus of  claim 1  further comprising a reservoir disposed in the main housing section configured to dispense a liquid soap onto at least one of the plurality of rotating heads. 
     
     
         19 . The apparatus of  claim 1  further comprising a reservoir in the main housing section configured to dispense liquid soap through at least one of the plurality of rotating heads. 
     
     
         20 . The apparatus of  claim 1  wherein the wall mounting means comprises suction cups for attaching the main housing section to the vertical surface.
