<p>The present invention relates to a funnel for preventing liquid overflow capable of safely pouring liquid, when the fluid such as sesame oil is injected, by stopping supply of the fluid by automatically closing an outlet of the funnel with a stopper by a floating material, moving according to the level of fluid, when the fluid in a container reaches a full water level. The funnel for preventing liquid overflow of the present invention comprises: an injection unit having a trumpet shape having a wide upper part and a narrow lower part; an insertion unit extended from a lower part of the injection unit, inserted into the container, having a tubular shape to discharge the fluid injected into the injection unit to an inside of the container; a floating material generating buoyancy according to a level of fluid in the container; a seesaw switch installed in the insertion unit an having one side and the other side inversely rotating about a rotating axis according to a movement of the floating material; a first connection part connected between the floating material and the one side of the seesaw switch; a stopper installed in the injection unit and opening and closing the outlet of the injection unit by rotating about a hinge axis according to the movement of the floating material; a second connection part connected between the other side of the seesaw switch and the stopper; a neck unit formed between the injection unit and the insertion unit and having a diameter of an outer circumferential surface thereof having smaller than that of an upper part of the insertion unit; and a circular magnet ring installed on the outer circumferential surface to be vertically moved.</p> |
