1. A water/soap dispenser, comprising:
a substantially hollow housing adapted to be mounted to a faucet, the housing having a top, a bottom, an outlet for liquid to pass through, and a hollow chamber, the chamber adapted to hold a cleaning product therein; a pipe assembly including an elongate elbow pipe having a first end extending outside said housing, a leg section extending through said housing, the leg section including the first end, and a second end extending towards the outlet of said housing and communicating therewith, an intermediate pipe extending orthogonal to the leg section and opening in the top of said housing, the intermediate pipe being in fluid communication with the leg section, and an internal baffle disposed between the leg section and the second end of the elbow pipe, the baffle having a pass-through opening defined therein; the pipe assembly disposed inside the chamber, the pipe assembly defining a passage for flow of water from the faucet towards the outlet and dispensing of the cleaning product into the water flow; a water valve assembly coupled to the pipe assembly, the water valve assembly selectively opening and closing to control flow of the water from the faucet through the pipe assembly; a pump assembly coupled to the pipe assembly, the pump assembly selectively dispensing the cleaning product into the water flow; the pump assembly including: a pump outlet coupling having, an outlet pipe extending into the pump outlet coupling, and an intermediate reservoir extending out of the pump outlet coupling, the intermediate reservoir being coaxially aligned with the outlet pipe and communicating therewith, the intermediate reservoir being adapted to trap a quantity of the cleaning product therein to be dispensed through the outlet pipe during a pumping operation, the pump outlet coupling coupled to the second end of the elbow pipe; an elongate piston casing extending into the chamber from an interior side wall of the housing, the piston casing being spaced from and in coaxial alignment with the intermediate reservoir; an elongate piston reciprocally mounted within the piston casing, the piston being adapted to reciprocate between start and end positions, the elongate piston having a first end and an opposing second end, the first end of the piston extending outside the housing, an abutment flange disposed between the opposing ends of the piston, and a piston head disposed at the second end of the piston, the abutment flange limiting movement of the piston to be within the piston casing; and a biasing spring disposed inside the piston casing, the biasing spring normally biasing the piston into the start position; wherein selective reciprocation of the piston moves the piston head into and out of the intermediate reservoir to forcibly eject the cleaning product through the outlet pipe, the start position corresponding to a position outside the intermediate reservoir, the end position corresponding to a position inside the intermediate reservoir; and a universal actuator pivotally mounted to the valve assembly; wherein selective operation of the universal actuator substantially concurrently activates the valve assembly and the pump assembly to permit water flow through the pipe assembly and to dispense the cleaning product into the water flow. |
