Abstract

The utility model relates to an automatic sealing floor drain, which mainly consists of a preburied sleeve ring, a water guide tube and a sealing plate, wherein the preburied sleeve ring is preburied at an inlet of a water drain pipe for fixing the position of the water guide tube, the lower end of the water guide tube is provided with a half circle of projected step, the step has the effects of accumulating water and blocking the sealing plate for maintaining the horizontal position, the sealing plate is connected at the lower end of the water guide tube in a penetrated way by a shaft, the sealing plate can move around the shaft, the sealing plate is divided into two half circles by the shaft, a balance weight is added on the small half circle, preferably, the weight of the balance weight is a little greater than that of the large half circle, the balance weight has the effect that when the floor drain losses the water flushing force after the water drain, the small half circle end can downwards rotate around the shaft until the step at the lower end of the water guide tube blocks the rotation of the small half circle end, so the sealing plate always maintains at the horizontal position. At the time, the lower end edge of the small half circle is in horizontal contact with the projected step of the water guide tube, and the upper end edge of the large half circle is in horizontal contact with the lower port of the water guide tube. Because both the two contact modes are horizontal contact, the gap of the contact surfaces is very small, when the water flow is small, water can be absorbed and attached in the gap when flowing into the gap because of the water absorption characteristics, and a sealing surface is formed on the horizontal plane. Thereby, the goal of preventing odor from being leaked out can be reached.
