摘要： An improved bug-proof and odor-proof draining outlet structure is particularly adapted for use on floors and is equipped with a pair of symmetric semi-circular blockage flaps that are pivotally fixed at the bottom periphery of the draining outlet and are one-way openable. At one side of each flap is disposed a counterweight so that as water is discharged via the blockage flaps, the same will be pushed opened, permitting water to be expelled out, and then automatically closed due to gravity exerted on the counterweights. Water is directly discharged into a duct without moving against the wall of the duct so as to make the discharge of the water in a more smooth and effective manner. Besides, the bottom periphery of the draining outlet is provided with a pair of supporting lugs each having a slot-like opening so that a pivot pin fixed to the underside of each blockage flap can be in snap engagement with each supporting lug with ease.
