The present invention relates to a one-touch drain opening and closing device comprising: a body having a second screw thread in an outer peripheral surface, and an ascent and descent inducing groove in an inner peripheral surface; a vertically moving gear inserted into the body, having a first gear part in an upper part, an inserting groove in the inner side of an upper part, a third screw thread in the outer peripheral surface of a lower part; a rotation gear inserted into the inserting groove of the vertically moving gear, having a second gear part engaged with the fist gear part, and a second inserting groove in an upper part; an elastic member inserted into the second inserting groove; a water stopper combined with the upper part of the body, having a rubber ring inserted into an outer peripheral surface, and a first screw thread corresponding to the second screw thread in an inner peripheral surface; and a vortex generator combined with the lower part of the body, having a bump piece at an incline from the upper part to the lower part in an outer peripheral surface, and a forth screw thread corresponding to the third screw thread in an inner peripheral surface. The present invention has an effect for reducing manufacturing costs by reducing the number of process steps and main components of a product, and reducing costs of a raw material by replacing metal with plastic as the raw material of the product. Moreover, the one-touch drain opening and closing device can be used semi-permanently since a user is able to repair the device simply and directly when a main component is repaired due to damage to or failure in the main component. The present invention has an effect for preventing foreign materials from being precipitated due to the faster drainage rate of water since a vortex generator combined with a lower part generates a vortex in drainage. |
