Referring to Fig. 1, the current trap body 11 is composed of the squatting pan interface 4, the water inlet end and the draining end. When the pipe part is separated, it will be dispersed at both ends, so that the dirt with certain viscosity will be deposited at the bottom, and there will be dead corners. Over time, the horizontal pipe will easily be blocked and it will not be easy to dredge. With the drainage system of this structure, the installation height of the toilet is 300mm, and the installation height of the squatting toilet is 450-550mm, which takes up a lot of floor space, increases the load of the building, and increases the construction cost of the building. Because most of the squatting toilets are originally equipped with water traps, relying on the water seal of the water traps in the pipes to achieve deodorization. Odor will come out, so the bathroom smells back, and when flushing, a resistance zone is formed at the front end of the tee and the drainage branch pipe, and a vacuum section is formed at the rear end, which has a certain containment effect on the sewage and affects the sewage discharge effect. cause clogging and leakage. Each use must increase the amount of flushing water, generally need more than 12-15 liters of water to rinse clean, greatly exceeding the 6 liters stipulated by the state, wasting water resources and wasting the resources of the people of the country. The flushing water leaks from the gap of the floor tiles or other pipe fittings into the settlement tank to form accumulated water, and the accumulated water is discharged into the main riser through the natural leakage of the accumulator, which completely solves the problem of saturated water in the settlement tank. Formation of stinky puddles or leakage to the next floor, overflow to other technical problems in this floor. In addition, there are technical problems such as squatting toilets, seat toilets, ordinary floor drains, and sanitary ware in the process of drainage (odor). There are positive and negative pressures between the branch pipe and the main pipe during the natural drainage process, and the main horizontal pipe reaches fullness. A vacuum section is formed between the water seal or the mechanical seal, which restricts and hinders the unobstructed drainage.
