However, after research and practice, it has been found that the toilets in this prior art have the following disadvantages:

Due to the setting of the water storage tank, when the solid waste falls to the water storage tank, the water splashing phenomenon is liable to occur, causing unnecessary pollution; and the water consumption of the water storage tank itself and the water consumption for replacement are increased, which is not conducive to water saving. Especially in places where water is scarce, there is no way to set and maintain water storage, and solid waste is very likely to adhere to the toilet area, causing unnecessary burden on cleaning. Due to the limitation of installation space, etc., the water storage rafts of many toilets cannot completely cover the falling area, and the sluice area without water sluice still has the phenomenon of adhering to solid waste even if the surface is smooth. Therefore, the toilet area of the prior art toilet is easily contaminated and is not easily cleaned.
