APPARATUS FOR INJECTING ANTISEPTIC SOLUTION WITHOUT SUPPLY OF ELECTRIC POWER

A device for injecting an antiseptic solution which automatically controls a supply amount of an antiseptic solution used in the sterilization process in proportion to a consumption amount of tap water, supplies the antiseptic solution without power, performs maintenance, management and repairing easily by constructing the device in a simple structure without electrical facilities, and reduces cost by preventing electric energy from being used in sterilization is provided. In an antiseptic solution supply device of water supply facilities having a water storage tank for storing raw water and an antiseptic solution tank for storing an antiseptic solution, a non-powered proportional control type device for injecting the antiseptic solution comprises: a housing(10) comprising an inflow port(11) formed at one side of the housing, a drain port(13) formed at the other side of the housing, and an inserting part(15) which is in communication with a pipeline for connecting the inflow port and the drain port; and an antiseptic solution transport means(20) which is inserted into the pipeline through the inserting part and discharges the antiseptic solution into the water storage tank by sucking an antiseptic solution from the antiseptic solution tank by water power of raw water flowing through the pipeline in such a way that a suction amount and a discharge amount of the antiseptic solution are proportionally controlled according to a flow amount of raw water passing through the pipeline.
