Soap dispensing scrubber

Abstract

A cleaning attachment and rotary tool for cleaning are provided. A cleaning attachment includes a housing, a plurality of bristles, and a drive shaft extending from the housing in an axial direction, the drive shaft being coupled to the housing such that rotation of the drive shaft causes rotation of the housing. The housing includes a reservoir, a valve for dispensing the fluid from the reservoir, and at least one resilient element surrounding an axis defined by the drive shaft. Translation of the drive shaft along the axial direction causes compression of the resilient element, and compression of the resilient element causes the valve to open to dispense fluid from the reservoir. A rotary tool for cleaning includes the cleaning attachment and a rotary tool having a motor, power source, and a chuck configured to receive the drive shaft of the cleaning attachment.

What is claimed is: 
     
         1 . A cleaning attachment for a rotary tool, the cleaning attachment comprising:
 a housing,   a plurality of bristles coupled to the housing, and   a drive shaft extending from the housing in an axial direction, the drive shaft being coupled to the housing, whereby rotation of the drive shaft causes rotation of the housing;   the housing comprising:
 a reservoir configured to contain a fluid, 
 a valve for dispensing the fluid from the reservoir, and 
 at least one resilient element surrounding an axis defined by the drive shaft; 
   wherein translation of the drive shaft along the axial direction causes compression of the resilient element, and   wherein compression of the resilient element causes the valve to open to dispense fluid from the reservoir.   
     
     
         2 . The cleaning attachment of  claim 1 , the housing having a body and a cap assembly, the reservoir being formed between the body and the cap. 
     
     
         3 . The cleaning attachment of  claim 2 , wherein the at least one resilient element comprises a flex region forming at least a portion of the cap assembly. 
     
     
         4 . The cleaning attachment of  claim 3 , wherein the flex region comprises undulating profile having at least one peak and at least one valley. 
     
     
         5 . The cleaning attachment of  claim 3 , wherein the flex region comprises a convex profile. 
     
     
         6 . The cleaning attachment of  claim 2 , wherein the cap assembly comprises an O-ring seal. 
     
     
         7 . The cleaning attachment of  claim 2 , the cap comprising a collar and an overmolded portion; wherein the resilient element is formed from the overmolded portion. 
     
     
         8 . The cleaning attachment of  claim 2 , further comprising a bracket configured to couple the cap and the drive shaft. 
     
     
         9 . The cleaning attachment of  claim 8 , the at least one resilient element further including a spring between the bracket and cap assembly. 
     
     
         10 . The cleaning attachment of  claim 2 , the at least one resilient element including a spring between the cap and the housing. 
     
     
         11 . The cleaning attachment of  claim 2 , the cap assembly being removably coupled to the body. 
     
     
         12 . The cleaning attachment of  claim 2 , the cap assembly being irremovably coupled to the body, the cap assembly further comprising a port for filling the reservoir. 
     
     
         13 . The cleaning attachment of  claim 1 , wherein the at least one resilient element extends around a circumference of housing. 
     
     
         14 . The cleaning attachment of  claim 13 , wherein the at least one resilient element comprises an elastomeric material forming a sidewall of the housing. 
     
     
         15 . The cleaning attachment of  claim 1 , wherein the at least one resilient element is inside the reservoir. 
     
     
         16 . The cleaning attachment of  claim 15 , wherein the at least one resilient element comprises a coil spring. 
     
     
         17 . The cleaning attachment of  claim 15 , wherein the at least one resilient element is seated on an endwall of the reservoir at a bottom end of the reservoir opposite the shaft. 
     
     
         18 . The cleaning attachment of  claim 17 , wherein the at least one resilient element comprises a coil spring. 
     
     
         19 . The cleaning attachment of  claim 17 , wherein the at least one resilient element comprises a ring of compressible thermoplastic material. 
     
     
         20 . A rotary tool comprising:
 a motor,   a power source electrically coupled to the motor,   a chuck coupled to the motor and having a longitudinal bore therein, and   a cleaning attachment, the cleaning attachment comprising:
 a housing, 
 a plurality of bristles coupled to the housing, and 
 a drive shaft extending from the housing in an axial direction, the drive shaft being coupled to the housing, whereby rotation of the drive shaft causes rotation of the housing; 
 the housing comprising:
 a reservoir configured to contain a fluid, 
 a valve for dispensing the fluid from the reservoir, and 
 at least one resilient element surrounding an axis defined by the drive shaft; 
 
   wherein the drive shaft is disposed within the longitudinal bore of the chuck so that rotation of the chuck causes rotation of the housing.
