[0023] During use: A water-sealed same-floor drainage floor drain provided in the first embodiment of the present utility model is connected to the bathroom sewer pipe and installed on the bathroom floor; with the development of the times, more and more old houses are facing renovation, and bathroom drainage is a very headache problem. The interlayer bathroom drainage system is pre-buried under the ground, and it is very inconvenient to break the ground. The same-floor drainage is more and more popular. For the sunken same-floor drainage system, since it is necessary to sink the floor by 200 mm - 350 mm, the old houses often do not adopt the structural floor sinking during the construction process. If the elevated renovation is adopted, it will occupy a small part of the height space of the bathroom, and the whole bathroom will appear relatively depressing. The same-floor drainage floor drain is a pipeline component pre-set in the bathroom floor, and its purpose is to block the odor during the use of the bathroom. However, this component needs to sink the floor or be elevated, which is not suitable for the renovation of old houses. Therefore, we need to reduce the height of the floor drain, but still need to include a water seal to block the odor. An ultra-low-height water-sealed same-floor drainage floor drain can not only not require floor sinking, but also block the odor through the water seal.
