The invention relates to a plugging device for a drainage port and aims to solve the problem that the drainage port wastes water and is needed to be supported by external force. The plugging device consists of a flexible pipe of which the upper end is fixedly connected with a toilet stool or the drainage port, and the lower end is extended into a drainage pipeline or a pit latrine, and a magnetic extruding and clamping device which is arranged at the lower end of the flexible pipe; according to the magnetic extruding and clamping device, pocket frames are arranged in the middles of two sides of the lower end of the flexible pipe, and at least one pair of magnetic suction clamp plates of which the width is equal to the width of a flattened flexible pipe or suction clamp plates equipped with permanent magnets are fixedly connected with the pocket frames in the horizontal direction. At least one end of each suction clamp plate is provided with at least one pair of the permanent magnets. The lower end of the flexible pipe is immersed in a water seal of the toilet stool, the drainage pipeline or the pit latrine. The permanent magnets are formed by superposing common ferrite magnets on neodymium ferrum boron strong magnets. The plugging device has the advantages that the drainage port can be plugged temporarily under the condition that external force and water are not used, or little water is used.

The invention described herein includes a latrine pan and collector system for use in an offset pit latrine. The system permits use of a latrine pan having a flapper in an offset leach pit context, and eliminated the necessity of large scale installation of a concrete collection box, which can collect unsanitary debris. The system of the invention includes (1) a pour-flush latrine pan and (2) a collector.
