1. A condensation water trap device comprising:
a neutralizing unit including an inlet to introduce condensation water, an inner space to receive a neutralization agent for neutralizing the introduced condensation water, and a condensation water passage to allow condensation water, which is neutralized in the inner space by the neutralization agent, to flow out;
a discharging unit including a storage space to store the condensation water directly or indirectly introduced through the condensation water passage, an outlet open in a circular shape such that the stored condensation water is discharged, a ball having a spherical shape and seated on the outlet to close the outlet, and a packing having an annular shape to surround the outlet, while extending to be inclined upward toward a radial center of the outlet from a rim of the outlet, such that an outer circumferential surface of the ball makes contact with the packing when the ball is seated on the outlet, and
a packing seating part in the annular shape protruding in the vertical direction and formed at an area adjacent to the outlet such that the packing is seated on an inner circumferential surface of the packing seating part,
wherein the packing has a packing base part surrounding the outlet, and a protrusion part extending to be inclined upward toward the radial center of the outlet from the packing base part so that the protrusion part has a blade-like shape and makes contact with the ball, and
wherein the protrusion part is formed of a material having elasticity, and curved and deformed downward in a vertical direction by a weight of the ball, when the ball is seated.
