Abstract
The utility model discloses a back-overflow preventing floor drain which comprises an outer sleeve. A guide cylinder with big end up is clamped inside the outer sleeve, a filter screen is arranged on the upper mouth of the guide cylinder, and a water storage bowl is arranged below the guide cylinder. The water storage bowl is tightly pressed in the outer sleeve through the edge of the guide cylinder, and a seal ring is arranged between the water storage bowl edge and the guide cylinder edge. A water outlet is arranged on the upper portion of the water storage bowl, the lower port of the guide cylinder is positioned inside the water storage bowl, and a hollow ball-shaped plastic reversing valve capable of sealing the lower port of the guide cylinder is arranged in the water storage bowl. The back-overflow preventing floor drain is simple and reasonable in structure, can effectively prevent the backflow water from back overflowing, and also has the function of preventing odor, insects and rat. The plastic reversing valve floats upwards to maintain the sealed lower port of the guide cylinder always in a sealing status when water exists in the water storage bowl, and water flow strikes the plastic reversing valve in the water draining process, the lower port of the guide cylinder opens, sewage can be discharged into a pipe line through the water outlet of the water storage bowl, and due to the fact that the seal ring is arranged between the water storage bowl and the guide cylinder, the backward overflowing of the backwater through the clearance between the water storage bowl and the guide cylinder can be avoided.
