1. A washable faucet lever with crank-activated detergent dispenser comprising:
a lever cartridge having a stem operably coupled to a hand lever configured to rotate in a lever axis of rotation and operably coupled to a two-bar linkage configured to rotate in a linkage axis of rotation parallel to and simultaneous with the lever axis of rotation;
a detergent reservoir member configured to house a liquid detergent therein, having an internal channel configured to receive the liquid detergent, and having a reservoir valve coupled to the detergent reservoir member and operably configured to selectively translate to open and permit flow of the liquid detergent through the internal channel and to close and restrict flow of the liquid detergent through the internal channel;
an encasement member defining an enclosed region therein, defining an outlet, having an outlet valve disposed within the enclosed region and operably configured to selectively translate to open and permit flow of the liquid detergent through the outlet, to close and restrict flow of the liquid detergent through the outlet, and biased with a spring retained by the encasement member; and
a piston disposed within the enclosed region, coupled to the two-bar linkage, and operably configured to translate within the enclosed region upon rotating the hand lever in the lever axis of rotation to selectively and simultaneously displace the reservoir valve and outlet valve to permit flow of the liquid detergent through the internal channel, into the enclosed region, and out through the outlet.
