Siphon draining device

Abstract

The siphon draining device of the present invention at least comprises a water collecting component and a drainage component. The water collecting component provides with a groove portion, and a reserved hole is provided in the groove portion to accommodate the drainage component. The groove portion is formed by four side walls and a bottom wall, and a small outward extension surface forms above the four side walls to be combined with the drainage hole of the drainage groove of a building. Said drainage component arranges inside the water collecting component. The drainage component provides with a guide element. The first guide plate of the guide element can block solid objects such as leaves and garbage, allowing rainwater to flow down to the second guide plate of the guide element and be smoothly guided. The guide element combines with a receiving element to form a guide hole, and then the lower receiving portion of the receiving element combines with the reserved hole of the water collecting component. Before the receiving element combines with the water collecting component, a first leak-stopping component is provided, a second leak-stopping component provides around the lower part of the reserved hole of the water collecting component, and an auxiliary combining element provides below the second leak-stopping component. Finally, a fastener assembly is used to fasten each component together from top to bottom, and the lower receiving portion of the receiving element can be combined with an external water pipe to allow rainwater to be discharged smoothly.
