On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0044] Reference Figures 1 to 3 As shown, in one embodiment of the present application, a quick-drainage toilet is proposed, comprising: a toilet body 1 and a sewage pipe 2, wherein at least one section and / or multiple sections of the sewage pipe 2 are designed to be a curved pipe structure that satisfies a quick-drainage curve model, wherein the quick-drainage curve model is determined based on the principle of the fastest descent curve.

[0045] Research has shown that the most rapid descent curve is a curve with the fastest falling speed. Therefore, the embodiment of the present application establishes a rapid drainage curve model based on the principle of the most rapid descent curve, and through mathematical derivation, rigid body dynamics simulation analysis, and fluid analysis in the pipeline, it is proved that the rapid drainage curve in the rapid drainage curve model is the curve with the fastest drainage speed in the sewage pipeline. Therefore, at least one section and / or multiple sections of the sewage pipeline are designed to be a curved pipe structure that meets the rapid drainage curve model, so that sewage can be discharged quickly along the pipeline curve, thereby enhancing the sewage discharge capacity of the toilet.

[0046] Specifically, the curve equation in the tachymetric curve model is x=a(θ-sinθ), y=a(1-cosθ), where θ represents any angle in the range of 0 to 2π, and a represents the magnification of the tachymetric curve; preferably, in the tachymetric curve model, the value range of the tachymetric curve magnification is 40 to 55.
