ABSTRACT:
Disclosed is a liquid dispensing apparatus capable of regulating a discharged amount of liquid. The apparatus comprises a main body having a liquid storing part formed therein and a protrusion part communicated with the liquid storing part at a side of the main body, downwardly protruded and having a threaded part formed therein, a support member having a liquid supply aperture formed thereto being provided to an inside of the protrusion part; a liquid discharge-operating member supported to be vertically movable on the support member provided to the protrusion part of the main body and controlling a liquid inflow into the protrusion member; a cover fixed on an upper part of the main body to which the liquid discharge-operating member is supported and having a hole through which a part of the liquid discharge-operating member is protruded and an opening into which a liquid supply receptacle is inserted and fixed; a liquid discharging member thread-engaged to be relatively movable to the threaded part of the protrusion part, capable of changing an inner space formed with the protrusion part and vertically moved as the liquid discharge-operating member is vertically moved, thereby discharging the liquid to an exterior; and a lever rotatably mounted to the main body and pressing the liquid discharge-operating member protruded through the hole of the cover to move the liquid discharge-operating member.
