Pump water soap dispensing mechanism

Abstract

A dispensing valve unit, adapted to be quickly filled with tap water, permitting the user to selectively rotate for dispensing selections, then pump to deliver soap and water or water only to an outlet. Composing a pair of partially interfitted tubular assemblies, forming there between an upper pump piston assembly and a lower soap valve cylinder assembly. The pump handle assembly is adapted to hold water and includes a piston and seal means and substantially right angle fill port. The cylinder assembly is operatively mounted to a mop base with cam means. The cylinder includes a locking collate and inner valve seat. Located within the cylinder is a pair of shiftable valve bodies. Upper body is a soap valve dispensing capsule, including a valve follower stem that protrudes of a ball end there of. The valve capsule is positioned to interactively engage cylinder valve seat cooperatively defining two different fluid passage way. The lower valve body includes a protruding tube cam means. First passage way: both valves are shifted up stream, lower valve pushes the ball stem end of upper valve away from cylinder seat, while holding soap valve closed. Pump water flows around past upper valve through lower valve and out tube for rinse water. Second passage way: both valves are shifted down stream, upper valve is against cylinder seat, lower valve is spaced back from upper valve. Pump water flows through upper valve, mixing with soap through lower valve out tube for soapy water.

I claim:  
     
         1 . A dispensing valve unit adapted to be quickly filled with tap water, permitting the user to selectively rotate the said dispensing valve unit to deliver soap and water, or water only to an outlet. 
 The said dispensing valve unit comprising: 
 a pair of partially interfitted tubular assemblies forming there between an upper pump assembly and a lower cylinder assembly. A said pump handle assembly is adapted to store water and includes piston means and substantially right angle fill port. A said lower cylinder assembly is operatively mounted for selectable rotation to a mop base fitted with cam means. Said lower cylinder assembly includes collet locking means and an inner valve seat; located within said cylinder is a pair of shiftable valve bodies:  
 the upper said valve body is a soap valve capsule adapted with a fill cap, and a soap reservoir, and soap dispensing valve including a stem valve follower that protrudes out through a ball end thereof; the said valve body is removable for refill. The said upper valve body is positioned, wherein the said ball end can interactively engage said cylinder valve seat cooperatively, defining two different passageways; the lower said valve body includes outwardly protruding tube that serves as a cam lobe against said cam means;  
   the first passageway: 
 both said valve bodies are shifted upstream wherein lower said valve body pushes the said stem ball end of upper said valve body away from said cylinder valve seat, while holding said soap valve closed; pumped water will flow down around upper said valve body out said to for rinse water delivery.  
   the second passageway: 
 both said valve bodies are shifted downstream wherein upper said valve body abuts said cylinder seat, and lower said valve body is spaced down away from said stem ball end; pumped water flows down through upper said valve body through said said soap valve and out tube to deliver soapy water.  
   
     
     
         2 . A dispensing valve unit of  claim 1  said fill port being substantially right angle from cylinder.  
     
     
         3 . A dispensing valve unit of  claim 1  wherein said cylinder assembly is operatively mounted for selectable rotation on a mop base.  
     
     
         4 . A dispensing valve unit of  claim 1  wherein complete valve unit structure is mounted to a mop base.  
     
     
         5 . A dispensing valve unit of  claim 1  said soap valve capsule adapted with fill cap and soap reservoir, and is removable to refill as needed.  
     
     
         6 . A dispensing valve unit of  claim 1  wherein ball valve end of said soap valve capsule interacts with said cylinder seat to cooperatively define two different fluid passages.  
     
     
         7 . A dispensing valve unit of  claim 1  wherein a said lower valve body is axially shifted by the rotation of cam means.  
     
     
         8 . A dispensing valve unit of  claim 1  wherein shifting up of said lower valve body against said valve stem holds said soap valve capsule away from said cylinder valve seat, while holding said inner soap valve closed.  
     
     
         9 . A dispensing valve unit of  claim 1  wherein said upper pump assembly can be removed to allow the removable of said soap valve assembly to refill with soap as needed.  
     
     
         10 . A dispensing valve unit of  claim 1  wherein said soap valve presents a flat resilient sealing surface surrounding soap metering stem, and sealing against a seat surface made up of two protruding radial sealing surfaces with at least one water port between, including a hole in the center for soap communication and to receive said metering stem.
