A faucet that includes a housing with a water supply assembly, a soap supply assembly, first and second sensing probe assemblies, and a controller provided in the housing, wherein a sensing region of the first sensing probe assembly is an upper portion of the housing, a sensing region of the second sensing probe assembly is a lower portion of the housing, an output terminal of each sensing probe assembly is electrically connected with an input terminal of the controller, and an output terminal of the controller is electrically connected with a control terminal of each of the water and soap supply assemblies. The controller controls the water supply assembly to start/stop water supply according to the sensing signal from the first or second sensing probe assembly, and controls the soap supply assembly to start/stop soap supply according to the sensing signal from the first or second sensing probe assembly.

Multifunction faucet

A plural material dispensing system () includes a pump () having a cylinder () mounted between a first bracket () and a second bracket (), a piston () disposed within the cylinder (), and a pump rod () extending from the piston () and out of the first bracket (). Material is provided to the cylinder () through a flow path extending through the pump rod (). The piston () drives material downstream out of the cylinder (), and the interface between the piston () and the inner surface of the cylinder () provides a dynamic seal during pumping. The flow of material into and out of the pump () is controlled by actively-controlled inlet and outlet valves.
